Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a method, an apparatus, a base station, and a terminal for transmitting MTC system information.

Background

MTC (Machine Type Communication) refers to Communication between machines without human intervention, and is widely used in smart cities, such as meter reading; intelligent agriculture, such as acquisition of information of temperature and humidity; intelligent transportation such as sharing a single vehicle. The conventional MTC physical downlink control channel PDCCH is deployed in a 4G LTE (Long Term evolution) spectrum, and shares frequency resources and partial channels with LTE users.

In the related art, the MTC system attaches to a 4G LTE system to deploy resources, and does not map PBCH resources of a physical broadcast channel of the MTC system at a physical resource position occupied by a control channel region of a preset subframe, i.e., a region corresponding to 3 OFDM symbols before a subframe and a CRS (cell reference signal) within a time period of broadcast system Information of the LTE system, e.g., a master Information block mib (master Information block), e.g., 40 ms.

With the development of communication technology, the mobile communication network gradually evolves to a 5G NR (New Radio) network, and the LTE system will gradually exit from the mobile cellular network, at which time the spectrum resources of the LTE system will be replanished as 5G NR spectrum resources. Since the life cycle of the MTC system is long, which may be up to ten years, the MTC system may still exist after the LTE system exits the mobile cellular network, and thus PBCH resources of the MTC system need to be deployed independently to carry system information, such as MIB, of the MTC system. If the PBCH resource of the MTC system is still deployed according to the related technology, the control channel resource of the original LTE system will be left unused, resulting in resource waste.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

It is to be understood that although the terms first, second, third, etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.

The execution body to which the present disclosure relates includes: the base station and the terminal in the 5G network, wherein the base station can be a base station provided with a large-scale antenna array, a sub-base station and the like. The terminal may be a device for transmitting machine type communication services, referred to as MTC device for short, such as an intelligent electric meter, a shared bicycle, or the like. In the specific implementation process, the base station and the terminal are independent and are simultaneously associated with each other, and the technical scheme provided by the disclosure is implemented together.

The application scenario of the present disclosure is: the MTC system is independently deployed without being attached to the original 4G LTE system, for example, the spectrum resources of the original 4G LTE system are replanted to the spectrum resources of the 5G NR system.

In the original 4G LTE system, the MTC device needs to share spectrum resources and channels with LTE users, that is, the MTC system is attached to the original 4G LTE system. Due to the narrow-band transmission characteristic of the MTC service, when the base station performs resource mapping for the MTC system, physical resources are mapped for the MTC system not in the existing Control Region (Control Region), i.e., the time-frequency Region corresponding to the first 3 OFDM symbols of a subframe, but in the Data Region (Data Region) of the subframe, i.e., the time-frequency Region corresponding to the last 11 OFDM symbols.

Correspondingly, when the base station performs physical broadcast channel PBCH resource mapping in a preset subframe for the MTC system, the base station also does not map MPBCH resources in the control region of the preset subframe. The preset subframe includes: subframe number 0 and subframe number 9 in an MTC FDD (Frequency Division duplex) system; and subframe No. 0 and subframe No. 5 in an MTC TDD (Time Division duplex) system. The MPBCH resource is used to carry basic system Information of the MTC system, such as a master Information block mib (master Information block).

For example, refer to fig. 1-1 for a schematic diagram of mapping of MPBCH resources in MTC FDD normal CP mode in LTE system. In an MTC system attached to an original LTE system, when the system adopts an MTC FDD normal CP mode to transmit information, a base station repeatedly broadcasts preset MTC system information such as MIB information in a broadcast period with the duration of 40ms through MPBCH resources deployed in a No. 0 subframe and a No. 9 subframe, wherein R0 in the figure represents the first broadcast in the broadcast period; r1, R2, R3, R4 respectively represent the first, second, third, fourth repeat broadcasts. PSS/SSS respectively represent Primary and secondary Synchronization signals, and PSS is called Primary Synchronization Signal, namely a Primary Synchronization Signal; the SSS is called a Secondary Synchronization Signal, i.e., a Secondary Synchronization Signal.

After the LTE system exits the mobile cellular network, the control region of the preset subframe in the original LTE system, i.e., the time-frequency region corresponding to the first 3 OFDM symbols, is vacated to become a blank resource. As in the above example, after the LTE system exits the mobile cellular network, the control regions of the subframe No. 0 and the subframe No. 9 shown in fig. 1-1 will be vacated as blank resources, as shown in fig. 1-2.

Based on this, the present disclosure provides a method for transmitting MTC system information, which can transmit preset system information of the MTC system, such as MIB information, by using control region resources of preset subframes in an original LTE system when a base station independently deploys MPBCH resources for the MTC system, thereby improving transmission efficiency of the MTC system information.

Referring to fig. 2, a flowchart of a method for transmitting MTC system information according to an exemplary embodiment is shown, where the method is applied in a base station, and the method may include the following steps:

in step 11, determining the information detection capability of the MTC equipment in the cell;

the information detection capability of one MTC device is used to indicate whether the MTC device supports searching for preset MTC system information, such as MIB information, from a target resource region.

The time-frequency range of the target resource region is as follows: a time zone corresponding to a control zone of a preset subframe of the original LTE system is equal in time domain; and the frequency domain is equal to a frequency resource region occupied by preset MTC system information in the original LTE system. Wherein, the preset MTC system information includes: information required for the MTC device to access the base station cell, such as MIB information. And the MTC equipment can access the cell covered by the base station after receiving the preset MTC system information issued by the base station.

Accordingly, the frequency region of the target resource region may be the frequency resource region occupied by the MPBCH resource mapping region in the original LTE system.

Still taking the MTC FDD normal CP mode as an example, the mapping region of the MPBCH resource in the original LTE system is a time-frequency region occupied by data regions of preset 6 PRB pairs of subframes No. 0 and No. 9; the data region of one subframe refers to a time-frequency region corresponding to the last 11 OFDM symbols of one subframe. The time-frequency range of one PRB (physical resource block) is: a slot, namely 0.5ms, is formed in the time domain, wherein one slot includes 7 OFDM symbols symbol; the frequency domain includes 12 consecutive subcarriers, and if the frequency interval of one subcarrier is 15KHz, the frequency range of one PRB is 180 KHz. One PRB pair occupies 2 slots, i.e. 1ms, in the time domain; and includes 12 subcarriers in the frequency domain.

The present disclosure relates to two types of MTC devices, wherein one type of MTC device does not support searching for preset MTC system information from a target resource region, and may be referred to as a first type of MTC device in the present disclosure. The first MTC device may be an MTC device following an original LTE system transmission protocol, such as an existing rel.13-rel.15 terminal. Another type of MTC device may support searching for preset MTC system information from a target resource region, and may be referred to as a second type of MTC device in this disclosure.

Regarding how the base station determines the information detection capability of the MTC devices, in an embodiment, the base station may determine the information detection capability of each MTC device in the current cell according to the deployment information of the operator.

For example, the base station learns that only release 13 MTC devices are deployed by the operator in the cell according to pre-acquired operator deployment information, and may determine that the MTC devices in the current cell all belong to the first class of MTC devices.

In another embodiment of the present disclosure, after the MTC device accesses the base station cell, the base station may further determine the information detection capability of each MTC device according to the device capability information reported by the MTC device.

Referring to fig. 3, which is a flowchart illustrating another method for transmitting MTC system information according to an exemplary embodiment, step 11 may include:

in step 111, acquiring device capability information reported by each MTC device;

in this disclosure, after the MTC device accesses the cell, for example, after the MTC device accesses the cell network for the first time, the base station may request the MTC device accessing the cell network to report the device capability information, that is, the MTC device passively reports the device capability information. Or the MTC device actively reports the device capability information to the base station under a preset trigger condition, for example, when accessing a cell network covered by the base station. The device capability information includes at least: and information representing the information detection capability of the MTC equipment.

In step 112, the information detection capability of the MTC device is determined according to the device capability information.

In an embodiment of the present disclosure, the device capability information may include: and the preset indication value is used for indicating the information detection capability. Then step 112 is specifically: and determining the information detection capability of the MTC equipment according to the preset indicated value.

In an embodiment, the MTC device may be represented as belonging to a first class of MTC devices with a first indication value; and adopting a second indication value to indicate that the MTC equipment belongs to the second MTC equipment.

Assume that the protocol specifies: and using a bit in a designated field carrying the equipment capability information to represent the information detection capability of the MTC equipment. For example, the first indication value is 0, and the second indication value is 1.

The implementation process of the step 112 is as follows: if the base station detects that the preset bit position is set to 0 in the device capability information reported by one MTC device, such as UE1, it is determined that UE1 does not support searching for preset MTC system information from the target resource region, that is, it is determined that UE1 belongs to the first class of MTC devices. On the contrary, if the preset bit position is set to 1, it is determined that the UE1 supports searching for preset MTC system information from the target resource region, that is, it is determined that the UE1 belongs to the second type of MTC device.

In step 12, according to the information detection capability and a preset resource mapping mode, mapping a target physical resource in a time-frequency region corresponding to the preset subframe, where the target physical resource is used for bearing the preset MTC system information;

in this disclosure, the target physical resource is a resource for carrying preset MTC system information, and if the preset MTC system information is MIB information of an MTC system, the target physical resource is a PBCH resource of the MTC system, which is abbreviated as MPBCH resource. The following example describes the target physical resource as an MPBCH resource in detail.

According to different information detection capabilities of the MTC devices in the cell, the base station can map MPBCH resources in a time-frequency region corresponding to a preset subframe by adopting the following two mapping modes:

the first mapping mode is consistent with the original LTE system, and MPBCH resources are mapped in the original MPBCH resource mapping area. The original MPBCH resource mapping area can be seen in FIGS. 1-1.

A second mapping manner, which maps the MPBCH resource in an effective region of a preset subframe, wherein the effective region is a region excluding CRS (cell reference signal) resources in the preset subframe, and the effective region includes: time-frequency regions corresponding to the first 3 OFDM symbols of the original LTE system and the original MPBCH resource mapping region are, as shown in fig. 1-2, mapped with MPBCH resources in the blank space shown in fig. 1-2.

In the present disclosure, the base station may map CRS resources in a preset subframe with reference to the original LTE system, see the deployment of CRS APs0/1 and CRS APs 2/3 in fig. 1-2.

Regarding the mapping of the target physical resource, depending on whether the device types of the respective MTC devices in the cell are consistent, the implementation of step 12 may include two cases:

in a first case, at least one MTC device in the cell does not support searching for the predetermined MTC system information from the target resource region, that is, at least one first type MTC device is located in the cell.

In this case, the base station maps the MPBCH resource in the data area of the preset subframe according to the first mapping manner. The time region of the data region corresponds to the time region except the control region in the preset subframe, and the frequency region of the data region corresponds to the frequency resource region occupied by the preset MTC system information in the original LTE system.

Referring to FIG. 4-1, a diagram of an MPBCH resource mapping area of a preset subframe according to an exemplary embodiment is shown, the MPBCH resource mapping area of the preset subframe includes: in a time-frequency region corresponding to a preset subframe, a time-frequency region corresponding to the last 11 OFDM symbols of the 6 PRB pairs, that is, an original MPBCH resource mapping region, is preset.

In case two, the MTC devices in the cell support searching for preset MTC system information from a target resource region, that is, the MTC devices in the cell all belong to the second type of MTC devices.

In this case, the base station may default to use the second mapping method to map the MPBCH resource in the preset subframe, or the base station autonomously determines which mapping method to use to map the MPBCH resource in the preset subframe.

For the case that the base station autonomously determines the mapping manner, referring to fig. 5, a flowchart of another method for transmitting MTC system information according to an exemplary embodiment is shown, where step 12 may include:

in step 1201, determining a target resource mapping mode of the target physical resource;

in the embodiment of the present disclosure, if the base station determines that the MTC devices in the cell all belong to the second type of MTC device, it may autonomously determine to map the MPBCH resource in the preset subframe by using the first mapping manner or the second mapping manner according to the requirements such as configuration flexibility.

In step 1202, broadcast configuration information is generated according to the target resource mapping manner, where the broadcast configuration information is used to inform the MTC device of a mapping range of the target physical resource in the preset subframe;

in the embodiment of the present disclosure, after the base station autonomously determines the target resource mapping manner, broadcast configuration information may also be generated according to the target resource mapping manner, so as to inform MTC devices in a cell of the mapping range of the MPBCH resource.

In an embodiment, the broadcast configuration information may include: the target resource mapping means, such as the first mapping means.

In another embodiment of the present disclosure, the broadcast configuration information may also include: a specific mapping range of the MPBCH resource, such as the last 11 OFDM symbols.

In step 1203, the broadcast configuration information is sent to the MTC device through a broadcast signaling;

in the disclosure, the base station may broadcast the broadcast configuration information to each MTC device in the cell through a broadcast signaling, so that each MTC device may accurately locate a target search area when acquiring preset MTC system information.

In an embodiment, the broadcast configuration information may be carried by 1 bit arranged in a master information block MIB, for example, when the 1 bit is set to 0, a first mapping manner is indicated; otherwise, when the 1 bit is set to 1, the second mapping mode is represented.

In another embodiment of the present disclosure, after the MTC device accesses the cell network, the base station may also carry the broadcast configuration Information through 1 bit in an SIB (System Information Block), and broadcast the broadcast configuration Information to know the MTC device.

In the embodiment of the present disclosure, for the second case, that is, the case that each MTC device in the cell of the base station supports searching for preset MTC system information from a target resource region, the base station may autonomously determine which resource mapping method to use for MPBCH resource mapping according to the flexibility requirement; and generating broadcast configuration information to be broadcast to each MTC device, so that when the MTC device detects preset MTC system information, a target search area can be accurately positioned according to the broadcast configuration information, the detection efficiency of the MTC device on the preset MTC system information such as MIB is improved, and the efficiency of accessing the MTC device to a base station cell is improved.

In step 1204, the target physical resource is mapped in the preset subframe according to the target resource mapping manner.

According to the different mapping manners of the target resource, the implementation of the step 1204 may include:

in the first way, the target physical resource mapping is performed according to the first mapping way, which is the same as the above case, and is not described here again.

And secondly, mapping the target physical resources in a time-frequency region corresponding to the preset subframe according to a second mapping mode.

When the base station maps the MPBCH resources in a preset subframe according to the second mapping mode, the available effective mapping area comprises: a target resource region and an original MPBCH resource mapping region, such as a time-frequency region occupied by 6 PRB pairs in a preset subframe shown in FIG. 4-2.

In this disclosure, for the case that the base station maps the MPBCH resource according to the second mapping manner, the base station may determine how to map the target physical resource based on different MTC transmission modes and different types of MPBCH unit resources that need to be deployed in the original MPBCH resource mapping area.

In the related art, the MTC system may use the following four MTC transmission modes for information transmission, which are respectively: a Normal CP mode of machine type communication Frequency Division Duplex (FDD) conventional cyclic prefix (MTC FDD); a machine type communication frequency division duplex enhanced cyclic prefix MTC FDD Extended CP mode; a machine type communication Time Division Duplex (TDD) Normal CP mode with a conventional cyclic prefix (MTC); machine type communication time division duplex enhanced cyclic prefix MTC TDD Extended CP mode.

In each MTC transmission mode, a base station deploys four PBCH unit resources in an original MPBCH resource mapping region of a preset subframe, which are: PBCH symbol1, PBCH symbol 2, PBCH symbol3, PBCH symbol 4. The mapping manners of the four PBCH unit resources are also different in different MTC transmission modes, as shown in fig. 6-1, fig. 7, fig. 8, and fig. 9.

Based on this, referring to fig. 10, which is a flowchart illustrating another method for transmitting MTC system information according to an exemplary embodiment, step 12 may include:

in step 121, determining a target mapping sub-mode of the target resource region according to a preset MTC transmission mode;

the target mapping sub-pattern is used to indicate how to map target physical resources, such as MPBCH resources, in the target resource region.

In the present disclosure, step 121 can be implemented in at least the following two ways:

in a first embodiment, the target mapping sub-mode is determined according to protocol specification

In the present disclosure, the 5G NR protocol may preset a corresponding mapping sub-mode for each preset MTC transmission mode, and after the base station determines the MTC transmission mode adopted by the current cell, the corresponding target mapping sub-mode may be determined.

In an embodiment, the base station may query a preset resource mapping list according to the MTC transmission mode of the current cell, and determine a target mapping sub-mode corresponding to the MTC transmission mode. Wherein the preset resource mapping list comprises: a correspondence between the MTC transmission mode and a preset mapping sub-mode, the preset mapping sub-mode being used to indicate how to map PBCH symbols in the target resource region. For example, the preset resource mapping list may be as shown in table one:

watch 1

In the present disclosure, one target resource region includes three sub-regions. Each sub-region is equal to the duration of a symbol in the time domain; which is equal to the frequency range occupied by 72 consecutive subcarriers in the frequency domain, i.e. the frequency range occupied by 6 PRB pairs. The three sub-regions may be denoted as S0, S1, S2, respectively, corresponding to the three symbols in the target resource region.

Assuming that the base station determines that the MTC transmission mode of the current cell is the MTC FDD Normal CP mode, the look-up table one shows that the corresponding target mapping sub-mode is: sequentially mapping in the time-frequency regions corresponding to the first 3 OFDM symbols of the #0 subframe, namely the sub-regions S0, S1 and S2: PBCH symbol1, PBCH symbol 2, PBCH symbol 3; in sub-regions S0, S1, S2 of the #9 subframe, sequentially mapping: PBCH symbol1, PBCH symbol 2, PBCH symbol4, and the target mapping sub-pattern can be simply expressed as: (# 0: 1, 2, 3; # 9: 1, 2, 4).

By adopting the method, under the condition that the MTC equipment determines the MTC transmission mode and the second mapping mode adopted by the base station, the deployment condition of the base station on the MPBCH symbol in the target resource region can be determined according to the protocol specification, the base station does not need to inform the target mapping sub-mode through special signaling, and the signaling overhead is saved.

In a second embodiment, the base station may dynamically determine the target mapping sub-mode for a preset MTC transmission mode, that is, for the same MTC transmission mode, the target mapping sub-modes determined by the base station at different times may be different.

Referring to fig. 11, which is a flowchart illustrating another method for transmitting MTC system information according to an exemplary embodiment, step 121 may include:

in step 1211, determining the target mapping sub-mode according to the cell reference signal resource type mapped in the target resource region in the preset MTC transmission mode;

in the disclosure, for any MTC transmission mode, a base station may map CRS resources in a target resource region of a preset subframe according to the related technology of the original LTE system; and determining a mapping mode of the target physical resource in the effective area of the target resource area according to the CRS resource type mapped in the target resource area and the relationship between the PBCH symbol type and the CRS resource type in the original MPBCH resource mapping area. The effective region of the target resource region is a region excluding CRS resources in the target resource region. The types of CRS resources include: CRS APs0/1 and CRS APs 2/3. In the downlink, Antenna ports correspond to cell reference signals CRS one to one.

Before mapping the target physical resource, according to whether a CRS resource is set in a sub-region of the target resource region, the three sub-regions may be divided into: a first sub-region and a second sub-region. Wherein, be provided with the CRS resource in the first subregion, include: subregions S0, S1; CRS resources, i.e., a sub-region S2, are not set in the second sub-region, as shown in fig. 4-2.

In this disclosure, how to determine the MPBCH resource mapping manner of one sub-region may include:

determining the type of the sub-region to be mapped;

if the sub-region to be mapped belongs to the first sub-region, determining the MPBCH resource type to be mapped according to the CRS resource type mapped in the sub-region and the resource mapping condition of a target sub-region in an original MPBCH resource mapping region, wherein the CRS resources in the same type are deployed in the target sub-region.

As shown in fig. 6-1, the CRS resource types mapped in sub-region S0 of subframe No. 9 are: CRS APs 0/1; the type of the MPBCH resource to be mapped may refer to the MPBCH symbol mapped in the sub-region where the #4 symbol of the first slot, the #0 symbol of the second slot, and the #4 symbol of the second slot are located, and includes: PBCH symbol 2, PBCH symbol 1.

If the sub-region to be currently mapped belongs to the second sub-region, i.e., S2, any type of MPBCH symbol may be mapped within the sub-region.

According to the above rules and referring to fig. 6-1, fig. 7, fig. 8, and fig. 9, the resource mapping sub-modes corresponding to the four MTC transmission modes may be as shown in table two:

watch two

The base station can determine any mapping sub-mode as a target mapping sub-mode according to the second table.

For example, assuming that the MTC transmission mode of the current cell is the MTC FDD Normal CP mode, it can be known from the above table two that the mapping sub-modes that the base station can use include 16, as shown in table three:

watch III

The base station may determine any of the above modes as a target mapping sub-mode, such as mode two (1, 2, 3), (1, 2, 4).

In step 1212, generating mode configuration information according to the target mapping sub-mode;

after the base station determines the target sub-mapping mode, mode configuration information may be generated according to information of the target sub-mapping mode, so as to inform the MTC devices of the target sub-mapping mode.

In this disclosure, the mode configuration information may include a specific MPBCH symbol type, and for example, assuming that the target mapping sub-mode is the second mode, the mode configuration information may include: (1, 2, 3), (1, 2, 4).

In another embodiment of the present disclosure, a preset number of bits may also be used to represent the target mapping sub-mode. As in the above example, 4 bits may be used to represent the 16 mapping sub-mode corresponding to the MTC FDD Normal CP mode, for example, when the 4 bits are set to 0000, the mode one in the table three is represented. The mode configuration information may include: a bit value representing a target mapping sub-pattern. The bitmap mode is adopted to represent the target mapping sub-mode, so that the signaling overhead can be saved.

In step 1213, the mode configuration information is broadcasted through a preset broadcast signaling, so that the MTC device determines a mapping manner of the target physical resource in the target resource region according to the mode configuration information.

In the same way, the base station may carry the mode configuration information through broadcast signaling, and broadcast the mode configuration information to the MTC devices.

In the present disclosure, the base station may dynamically determine, according to the flexibility requirement, a mapping manner of the MPBCH resource in the target resource region in the preset subframe at different times, and broadcast the mode configuration information to the MTC device before the MTC device searches for MTC system information, thereby ensuring that the MTC device can accurately demodulate preset MTC system information, such as MIB information, from the preset subframe.

In step 122, mapping the target physical resource in the target resource region according to the target mapping sub-mode;

for example, still taking the MTC FDD Normal CP mode as an example, if the target mapping sub-mode determined in step 121 is the mode one in table three, the base station maps PBCH symbol1, PBCH symbol 2, and PBCH symbol3 in the target resource regions corresponding to the sub-frames 0 and 9 respectively in sub-regions S0, S1, and S2, and refer to fig. 6-2, which shows that the base station maps the target physical resources according to the second mapping manner.

Similarly, fig. 6-3 shows a schematic diagram of the MPBCH resource mapping in the target resource region when the target mapping sub-mode is the second mode. As shown, in sub-regions S0, S1, S2 of sub-frame No. 0, respectively: PBCH symbol1, PBCH symbol 2, and PBCH symbol3 map in sub-regions S0, S1, and S2 of sub-frame No. 9, respectively: PBCH symbol1, PBCH symbol 2, PBCH symbol 4.

FIG. 6-4 is a schematic diagram illustrating MPBCH resource mapping in the target resource region when the target mapping sub-mode is the third mode. As shown, in sub-regions S0, S1, S2 of sub-frame No. 0, respectively: PBCH symbol1, PBCH symbol 2, and PBCH symbol4 are mapped in sub-regions S0, S1, and S2 of sub-frame No. 9, respectively: PBCH symbol1, PBCH symbol 2, PBCH symbol 3.

FIG. 6-5 is a schematic diagram illustrating MPBCH resource mapping in the target resource region when the target mapping sub-mode is the fourth mode. As shown, in sub-regions S0, S1, S2 of sub-frame No. 0, respectively: PBCH symbol1, PBCH symbol 2, and PBCH symbol4 are mapped in sub-regions S0, S1, and S2 of sub-frame No. 9, respectively: PBCH symbol1, PBCH symbol 2, PBCH symbol 4.

In this disclosure, when mapping target physical resources for a second sub-region, that is, sub-region S2, if a to-be-mapped resource type indicated by the target mapping sub-mode is provided with preset CRS resources in an original MPBCH resource mapping region in a matching manner, when performing resource mapping on the second sub-region according to the target mapping sub-mode, the base station needs to map CRS resources of the same type in addition to mapping the to-be-mapped MPBCH symbol.

Still taking the MTC FDD Normal CP mode as an example, if the target mapping sub-mode determined in step 121 is sixteen as the mode in table three, it can be seen that the resource types to be mapped of the sub-region S2 of the sub-frame 0 and the sub-frame 9 are: PBCH symbol 2, PBCH symbol 1. Both of them have corresponding CRS resources in the original MPBCH resource mapping region, as shown in fig. 6-1. For example, in the original MPBCH resource mapping region of the subframe No. 0, PBCH symbol 2 is bound and mapped with CRS APs0/1 or CRS APs 2/3. In an original MPBCH resource mapping area of the subframe No. 9, PBCH symbol1 is bound and mapped with CRS APs 0/1; then the base station needs to deploy CRS resources of the same type when performing resource mapping in the sub-region S2 of the target resource region according to the above-mentioned pattern sixteen.

For example, referring to fig. 6-6, a schematic diagram of MPBCH resource mapping in the target resource region when the target mapping sub-mode is the above-mentioned mode sixteen is shown. As shown, in sub-regions S0, S1, S2 of sub-frame No. 0, respectively: PBCH symbol1, PBCH symbol 2, and CRS APs0/1 are also mapped in sub-region S2; similarly, in the sub-regions S0, S1, and S2 of the sub-frame No. 9, respectively: PBCH symbol1, PBCH symbol 2, PBCH symbol1, and CRS APs0/1 are also mapped in sub-region S2.

It should be noted that, in another embodiment of the present disclosure, CRS APs 2/3 matched with PBCH symbol 2 may be further mapped in the sub-region S2 of the sub-frame No. 0.

Similarly, the resource mapping manner of the target region in other MTC transmission modes is similar to that in the MTC FDD Normal CP mode, which is referred to above, and is not described herein again.

In step 123, the target physical resource is mapped in the data area of the preset subframe according to a target physical resource mapping manner of the original LTE system.

The resource deployment of the base station in the original MPBCH resource mapping area in the present disclosure can be the same as that of the original LTE system. It should be noted that, the step 123 and the step 122 are not in sequence, and may be performed simultaneously. For example, referring to fig. 6-7, the resource mapping of subframes No. 0 and No. 9 in MTC FDD Normal CP mode is shown in correspondence with fig. 6-2.

In step 13, the preset MTC system information is broadcast through the target physical resource.

After the base station maps the target physical resource, the MTC system information such as MIB information can be loaded into the target physical resource and broadcasted to the MTC equipment in the cell, so that the MTC equipment obtains the preset MTC system information from the preset subframe and accesses the cell network according to the preset MTC system information.

In summary, with the method for transmitting MTC system information provided by the present disclosure, in an application scenario where a system deploys a physical broadcast channel resource independently for MTC devices, if the MTC devices support detection of preset MTC system information, such as MIB, from a target resource region of a preset subframe, that is, a control region of a preset subframe of an original LTE system, when a base station performs physical broadcast resource mapping, a target physical resource, that is, a PBCH resource, for carrying the preset MTC system information may be mapped in the target resource region of the preset subframe, so as to enhance a mapping range of the PBCH resource, improve a utilization rate of the system resource, and further improve transmission efficiency of the MTC system information.

Correspondingly, the disclosure also provides a method for transmitting the MTC system information, which is applied to the second MTC device, namely the MTC device supporting the searching of the preset MTC system information from the target resource region. The time zone of the target resource zone is a time zone of a control zone of a preset sub in the original LTE system, and is a time zone corresponding to the first 3 OFDM symbols of a preset sub-frame, as shown in fig. 1-1; the frequency region is a frequency resource region occupied by preset MTC system information such as MIB information in the original LTE system.

Referring to fig. 12, a flowchart of a method for transmitting MTC system information is shown according to an example embodiment, the method may include:

in step 21, acquiring preset MTC system information for accessing a cell network from a data region of the preset subframe, and accessing the cell network, wherein a time region of the data region is a time region excluding the control region from the preset subframe, and a frequency region of the data region corresponds to a frequency resource region occupied by the preset MTC system information in the original LTE system;

in the present disclosure, when an MTC device initially accesses a cell network, it still obtains preset MTC system information, such as MIB information, according to the related art, and accesses the MTC network system of the cell.

In step 22, broadcast configuration information issued by a base station is obtained, where the broadcast configuration information is used to inform the MTC devices of a mapping range of a target physical resource in the preset subframe, and the target physical resource is used to carry the preset MTC system information;

in an application scenario where the MTC device has accessed the cell network and needs to acquire the preset MTC system information again, for example, when the MTC device needs to update a system, or when the MTC device changes from an idle state to an active state, broadcast configuration information broadcasted by the base station may be received to determine a mapping range of a target physical resource, such as an MPBCH resource, as described in step 1202 and step 1203 above.

In step 23, preset MTC system information is detected in the preset subframe according to the broadcast configuration information.

Corresponding to the above steps 1202 and 1203, the implementation of the above step 23 includes two cases:

in case one, if the broadcast configuration information indicates that the mapping manner of the target physical resource is the first mapping manner, the MTC device still detects preset MTC system information in an original MPBCH resource mapping area corresponding to a preset subframe according to the related art, as shown in fig. 4-1.

In case that the broadcast configuration information indicates that the mapping scheme of the target physical resource is the second mapping scheme, the step 23 specifically includes: the MTC device detects the preset MTC system information in the valid mapping region of the preset subframe, as shown in fig. 4-2.

For the second case, the MTC device may detect the preset MTC system information in the effective mapping region of the preset subframe by using any one of the following methods:

referring to fig. 13, which is a flowchart illustrating a method for transmitting MTC system information according to an exemplary embodiment, step 23 may include:

in step 231, if the broadcast configuration information indicates that the mapping mode of the target physical resource is the second mapping mode, determining a target mapping sub-mode of the target resource region according to the MTC transmission mode of the current cell;

that is, if the broadcast configuration information indicates that the base station maps the target physical resource in the target resource region according to the second mapping manner, the MTC device needs to first determine the resource mapping manner, i.e., the target mapping sub-mode, of each sub-region in the target resource region.

In this disclosure, the MTC device may determine the target mapping sub-mode according to any one of the following manners:

first, the MTC device detects MTC system information according to a resource mapping mode specified by a system protocol, which corresponds to the first embodiment of step 121.

Namely, the step 231 is specifically: inquiring a preset resource mapping list according to the MTC transmission mode of the current cell, and determining a target mapping sub-mode corresponding to the MTC transmission mode, wherein the preset resource mapping list comprises: a correspondence between an MTC transmission mode and a preset mapping sub-mode, wherein the preset mapping sub-mode is used for indicating how the base station maps a Physical Broadcast Channel (PBCH) symbol in the target resource region;

the preset resource mapping list is shown in the table one.

In this disclosure, after determining the MTC transmission mode adopted by the base station, the MTC device may determine, according to the preset resource mapping list, a target mapping sub-mode adopted by the base station when deploying the MPBCH symbol in the target resource region.

In a second implementation manner, corresponding to the second implementation manner of step 121, the MTC device determines the target mapping sub-mode according to the mode configuration information issued by the base station.

Referring to fig. 14, which is a flowchart illustrating a method for transmitting MTC system information according to an exemplary embodiment, the step 231 may include:

in step 2311, receiving mode configuration information broadcast by the base station;

in step 2312, the target mapping sub-mode of the target resource region is determined according to the mode configuration information.

In the embodiment of the disclosure, the MTC device may determine, according to the mode configuration information broadcasted by the base station, which mapping manner is used to deploy the MPBCH symbol in the target resource region of the preset subframe, so that the subsequent MTC device may accurately analyze the preset MTC system information.

In step 232, the preset MTC system information is detected in the effective mapping region of the preset subframe according to the target mapping sub-mode.

After the MTC equipment determines a target mapping sub-mode, in a target resource region of the effective mapping region, demodulating part of preset MTC system information according to the target mapping sub-mode; and demodulating another part of preset MTC system information in the original MPBCH resource mapping area of the effective mapping area according to the related technology, thereby quickly analyzing the preset MTC system information.

Referring to fig. 15, which is a flowchart illustrating a method for transmitting MTC system information according to an exemplary embodiment, before step 22, the method may further include:

in step 20, reporting device capability information to the base station, where the device capability information is used to indicate whether the MTC device has a capability of searching for preset MTC system information from the target resource region, so that the base station determines the information detection capability of the MTC device.

In the embodiment of the present disclosure, after the MTC device accesses the cell network, the capability information of the MTC device may also be reported to the base station, so that the base station determines the information detection capability of the MTC device, which corresponds to the embodiment shown in fig. 3, and is not described herein again.

When the MTC device demodulates the preset MTC system information carried by the MPBCH resource, power accumulation needs to be performed on each symbol of the PBCH for a long time, and demodulation is attempted. Therefore, within a fixed time, the more MPBCH resources are deployed and transmitted, the more PBCH received power can be accumulated by the MTC device, and the probability of successfully demodulating the preset MTC system information is also higher. Therefore, by using the method for transmitting the MTC system information provided by the disclosure, when the base station maps the target physical resource in the preset subframe by using the second mapping mode, the system resource can be effectively utilized, and the demodulation efficiency of the preset MTC system information is improved.
