Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Out-of-Band Radiation requirement (OOB Radiation): when a terminal device transmits a signal, it needs to satisfy a power requirement on a transmission channel 10, and also needs to satisfy a corresponding out-of-band radiation requirement to avoid interference to other communication devices, as shown in fig. 1. Out-of-band emissions requirements include: general out-of-band emission requirements and additional out-of-band emission requirements.

General out-of-band emission requirements: the method is a basic out-of-band radiation requirement which needs to be met by terminal equipment during design, and is suitable for most frequency bands.

Additional Out-of-Band Radiation requirements (additional Out-of-Band Radiation or additional Spectrum Emission): the method is based on the general out-of-band radiation requirement of a country or a region, and aims at the extra formulated out-of-band radiation requirement of a specified frequency band, and the additional out-of-band radiation requirement is generally more severe than the general out-of-band radiation requirement.

That is, the out-of-band radiated signal may interfere with other communication devices under the current communication system, and may also interfere with other adjacent spectrum communication systems (e.g., navigation, satellite, private network, etc.). To avoid this potential interference, different countries or regions define a multi-network coexistence scenario in which interference may exist, and make additional out-of-band emission requirements based on the general out-of-band emission requirements.

As shown in fig. 2, in a multi-network coexistence scenario, this additional out-of-band emissions require the terminal device 14 to be informed by the current network 12 by way of system broadcast or dedicated signaling. When the terminal device 14 can meet the requirement of additional out-of-band radiation, it can transmit signals and access the corresponding cell; when the terminal device 14 does not meet the requirement of additional out-of-band radiation, the cell is considered as a bar (bar) forbidden state in the multi-network coexistence scenario, and the cell is not accessed.

The above-mentioned multi-network coexistence scenario and the corresponding additional out-of-band emission requirements are defined according to frequency bands in the Third Generation Partnership Project (3 GPP), as shown in the following table one, a bitmap with 8 bits is provided, and each bit represents different out-of-band leakage indicator requirements under the corresponding frequency band.

Watch 1

For example, additional out-of-band emission requirements such as NS _05, NS _05U, NS _100, etc. are defined for the band n1, where each Network Signaling (NS) value represents the corresponding additional out-of-band emission requirement. It is mandatory for the terminal to be satisfied. However, with the deployment of different systems in different countries or regions, new multi-network interference coexistence scenarios are discovered from time to time, and corresponding additional out-of-band emission requirements need to be defined, and then 3GPP is added as a mandatory requirement to be supported by the terminal.

The technical problem that above-mentioned technical scheme exists lies in: given the new introduction of a new additional out-of-band emission requirement NS _ X for the above-mentioned n1 band, it does not recognize this newly defined additional out-of-band emission requirement NS _ X for terminal devices that have been on the market before. If the base station allocates a cell of the n1 frequency band to the terminal device and the base station broadcasts the additional out-of-band emission requirement NS _ X, the terminal device considers that the cell is in the access prohibited state because the terminal device does not support the additional out-of-band emission requirement NS _ X, and thus a cell allocation failure occurs.

The embodiment of the application provides a technical scheme for avoiding the problems, namely the technical problem that the cell access may fail under the condition that the terminal equipment does not support some additional out-of-band radiation requirements.

Fig. 3 shows a block diagram of a communication system provided by an exemplary embodiment of the present application, which may include: access network 12 and terminal equipment 14.

Several network devices 120 are included in access network 12. Network device 120 may be a base station, which is a device deployed in an access network to provide wireless communication functionality for terminal devices. The base stations may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems using different radio access technologies, the names of devices with base station functionality may differ, for example in LTE systems, called eNodeB or eNB; in a 5G (5th Generation Mobile Communication Technology, fifth Generation Mobile Communication Technology) NR-U (New Radio in Unlicensed Spectrum) system, it is called a gbnodeb or a gNB. The description of "base station" may change as communication technology evolves. For convenience of this embodiment, the above-mentioned apparatuses providing wireless communication function for the terminal device 14 are collectively referred to as a network device.

Terminal devices 14 may include a variety of handheld devices, vehicle mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem with wireless communication capabilities, as well as various forms of user equipment, Mobile Stations (MSs), terminal devices (terminal devices), and so forth. For convenience of description, the above-mentioned devices are collectively referred to as terminal devices. The network device 120 and the terminal device 14 communicate with each other through some air interface technology, for example, a Uu interface.

The technical scheme of the embodiment of the application can be applied to various communication systems, for example: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS) System, a Long Term Evolution (Long Term Evolution, LTE) System, a Frequency Division Duplex (FDD) System, a Time Division Duplex (TDD) System, an Advanced Long Term Evolution (Advanced Long Term Evolution, LTE-A) System, a New wireless (New Radio, NR) System, an Evolution System of an NR System, an LTE-based System of an unlicensed band, a Universal Mobile telecommunications System (UMTS-Universal Mobile telecommunications System, a UMTS-based System, WiMAX) communication system, Wireless Local Area Network (WLAN), Wireless Fidelity (WiFi), next generation communication system, or other communication system.

Generally, the conventional Communication system supports a limited number of connections and is easy to implement, however, with the development of Communication technology, the mobile Communication system will support not only conventional Communication but also, for example, Device-to-Device (D2D) Communication, Machine-to-Machine (M2M) Communication, Machine Type Communication (MTC), Vehicle-to-Vehicle (V2V) Communication, and Vehicle networking (V2X) system, etc. The embodiments of the present application can also be applied to these communication systems.

Fig. 4 shows a flowchart of an information indication method provided by an exemplary embodiment of the present application. The method may be applied in the communication system shown in fig. 3. The method comprises the following steps:

step 402, the terminal device sends indication information to the network device, where the indication information is used to indicate an additional out-of-band emission requirement supported by the terminal device.

In step 404, the network device receives indication information from the terminal device.

Optionally, the network device determines one or more additional out-of-band emission requirements supported by the terminal device according to the indication information. The network device configures the terminal device with cells available for access according to one or more additional out-of-band emission requirements supported by the terminal device.

In summary, in the method provided in this embodiment, the terminal device sends the indication information to the network device, so that the network device can determine the additional out-of-band radiation requirement supported by the terminal device, thereby configuring a reasonable cell to the terminal device, and avoiding the problem of cell access failure when the terminal device does not support the additional out-of-band radiation requirement.

There are at least three different implementations of the above embodiments:

in the first mode, the terminal device actively reports the indication information to the network device.

And in the second mode, the network equipment sends an inquiry request to the terminal equipment, and the terminal equipment sends inquiry feedback to the network equipment, wherein the inquiry feedback carries the indication information.

And thirdly, when the cell access fails, the terminal equipment reports the indication information in the failure reason value.

Aiming at the first mode:

fig. 5 shows a flowchart of an information indication method provided by another exemplary embodiment of the present application. The method may be applied in the communication system shown in fig. 3. The method comprises the following steps:

step 502, the terminal device sends first indication information to the network device, where the first indication information includes a bitmap, and the bitmap is used for indicating an additional out-of-band emission requirement supported by the terminal device.

Optionally, the bitmap includes n bits, each bit corresponding to an additional out-of-band emission requirement. That is, n bits correspond one-to-one to n additional out-of-band emission requirements. When the bit value is the first value, the representative terminal device supports the additional out-of-band radiation requirement corresponding to the bit; and when the bit value is the second value, the terminal equipment does not support the additional out-of-band radiation requirement corresponding to the bit.

Illustratively, the first value is 1 and the second value is 0. Alternatively, the first value is 0 and the second value is 1.

Illustratively, the reporting format may be as shown in table two below (taking 8 bits as an example), and Network Signaling (NS) values supported by the terminal device on the frequency band a are indicated by a bitmap. If the terminal equipment supports the additional out-of-band radiation requirement of the current type, the corresponding bit is set to be 1, otherwise, the corresponding bit is set to be 0. The network signaling value represented by each bit and the corresponding additional out-of-band emission requirement can be specified in a predefined manner or directly corresponding to a specific table in the 3GPP standard.

For example, if the terminal device 1 is a terminal device before the network signaling value NS _ X is introduced into the 3GPP standard and does not support NS _ X, then its network signaling capability reported in the frequency band a is 11110000. And for the terminal device 2 to be a terminal after the network signaling value NS _ X is introduced into the 3GPP standard, the network signaling capability reported by the terminal device 2 in the frequency band a is 11111000.

Watch two

Optionally, the first indication information is carried in Radio Resource Control (RRC) signaling.

In step 504, the network device receives the first indication information from the terminal device.

Optionally, the network device receives an RRC signaling from the terminal device, where the RRC signaling carries first indication information, where the first indication information includes a bitmap, and the bitmap is used to indicate an additional out-of-band emission requirement supported by the terminal device.

Optionally, the network device determines one or more additional out-of-band emission requirements supported by the terminal device according to the first indication information. The network device configures the terminal device with cells available for access according to one or more additional out-of-band emission requirements supported by the terminal device.

In summary, in the method provided in this embodiment, the bitmap is used to indicate the additional out-of-band radiation requirement supported by the terminal device, and the number of bits required by the bitmap is small, so that overhead of air interface resources can be saved.

Fig. 6 shows a flowchart of an information indication method provided by another exemplary embodiment of the present application. The method may be applied in the communication system shown in fig. 3. The method comprises the following steps:

step 602, the terminal device sends second indication information to the network device, where the second indication information includes a document number and a full version number of the communication protocol, and the document number and the full version number of the communication protocol are used to indicate an additional out-of-band emission requirement supported by the terminal device.

Optionally, the terminal device reports the base station of the additional out-of-band radiation requirement that the terminal device can meet by reporting the document number and the full version number of the communication protocol supported by the terminal device.

Since the 3GPP protocol version that the terminal device can support after the terminal device is designed and manufactured is clear, such as 38.101-1v15.7.0 protocol version, the terminal device will meet the corresponding additional out-of-band radiation requirement in the protocol version. Wherein 38.101 is the document number and v15.7.0 is the full version number. The document number comprises 5 digits, the first 2 digits (38) are document series numbers, and the last 3 digits (101) are tail numbers. The full version number includes a three-level version number of frozen (Release), V15 is a first-level version number, 7 is a second-level version number, and 0 is a third-level version number.

In the related art, the terminal device only reports the document number and the first-level version number supported by the terminal device to the network device, for example, the 3GPP v15 version, and the network device cannot know whether the terminal device supports v15.7.0 or v15.8.0, that is, cannot know the sub-level version number supported by the terminal device. The additional out-of-band emission requirement may be introduced in a 3GPP standard version of a certain sub-level version number, for example, the additional out-of-band emission requirement NS _ X is introduced in the v15.8.0 version, and for the v15.7.0 version, the additional out-of-band emission requirement NS _ X is not supported. The terminal device follows the design of version v15.7.0 and cannot meet the additional out-of-band emission requirement NS _ X. If the network device configures the terminal device with frequency band a and broadcasts the relevant NS _ X network device signaling in the cell, the terminal device cannot access the cell.

Therefore, the terminal device may also implicitly notify the network device of the out-of-band emission requirement added to each frequency band that the terminal device can support by reporting the document number and the full version number that the terminal device supports, such as the version numbers of 38.101-1, 38.101-2, and 38.101-3. Since the additional out-of-band emission requirements to be met in the respective frequency bands are explicitly listed in these communication protocols. After receiving the document number and the complete version number of the communication protocol that the terminal device satisfies, the network device may know whether a cell needs to be configured for the terminal device, where the cell is located in the frequency band a and broadcasts the additional out-of-band radiation requirement NS _ X.

Optionally, the second indication information is carried in RRC signaling. The RRC signaling may be RRC for reporting radio access capability of the terminal. And the terminal equipment carries the second indication information in the wireless access capability.

In one example, AccessStratumRFFR1Release is used to represent the 38.101-1 specification version number, AccessStratumRFFR2Release is used to represent the 38.101-2 specification version number, and AccessStratumRFENDCRelease is used to represent the 38.101-3 specification version number. Of course, it is also possible to report several "document number + full version number" in one signaling. If other needs exist, other 'document number + complete version number' can be reported to the network equipment together. The corresponding RRC signaling content is as follows:

UE-NR-Capability::＝SEQUENCE{

……

accessStratumRFRelease AccessStratumRFRelease,OPTIONAL

……

}

＝>

AccessStratumRFRelease::＝SEQUENCE{

……

AccessStratumRFFR1Release AccessStratumRFFR1Release,OPTIONALAccessStratumRFFR2Release AccessStratumRFFR2Release,OPTIONALAccessStratumRFENDCRelease AccessStratumRFENDCRelease,OPTIONAL

……

}

step 604, the network device receives the second indication information from the terminal device.

Optionally, the network device receives an RRC signaling from the terminal device, where the RRC signaling carries a radio access capability of the terminal, the radio access capability carries second indication information, the second indication information includes a document number and a full version number of a communication protocol supported by the terminal device, and the document number and the full version number of the communication protocol are used to indicate an additional out-of-band radiation requirement supported by the terminal device.

Optionally, the network device determines one or more additional out-of-band emission requirements supported by the terminal device according to the second indication information. The network device configures the terminal device with cells available for access according to one or more additional out-of-band emission requirements supported by the terminal device.

In summary, in the method provided in this embodiment, the document number and the full version number are used to implicitly indicate the additional out-of-band radiation requirement supported by the terminal device, and since one document number and one full version number can indicate multiple additional out-of-band radiation requirements supported by the terminal device at the same time, the required number of bits is small, so that overhead of air interface resources can be saved.

And secondly, because the document number and the full version number are carried in the wireless access capability, a new RRC signaling does not need to be additionally designed, and the system design of the communication system can be simplified.

Fig. 7 shows a flowchart of an information indication method provided by another exemplary embodiment of the present application. The method may be applied in the communication system shown in fig. 3. The method comprises the following steps:

step 702, the terminal device sends third indication information to the network device, where the third indication information has k multiplexed bits, where the k bits are bits used to indicate an additional out-of-band emission requirement supported by the terminal device, and k is a positive integer.

In a communication protocol that has been frozen, some bits of signaling information are defined. These information bits have a known indication meaning or a reserved bit meaning, but the usage rate of these information bits is low. The "reserved bit meaning" means that no specific indication meaning is defined for the bit in the communication protocol that has been frozen, and a specific indication meaning will be defined for the bit in a future communication protocol.

In this embodiment, k bits in the third indication information are multiplexed, where the k bits are bits for indicating an additional out-of-band emission requirement supported by the terminal device, and k is a positive integer.

Where the third indication information is signaling with a known meaning and the k bits are bits with a known meaning (indicating some information or reserved bits). But since these k bits are rarely used, they are multiplexed in this embodiment to indicate the additional out-of-band emission requirements supported by the terminal device.

Optionally, the third indication information is signaling for reporting the capability of the terminal, for example, the third indication information includes a modified Maximum Power Reduction (MPR) behavior (modified MPR-behavviour), and 8 bits of the modified MPR behavior are rarely used for capability reporting. Thus, the 8 bits in the modified MPR behavior are multiplexed, extending its meaning to indicate the supported network signaling value or the supported "document number + full version number" of the terminal, informing the network device of the out-of-band leakage requirement supported by the terminal device.

Optionally, the multiplexed k bits in the third indication information include:

a first bit in the modified MPR behavior signaling, the first bit being a bit in the modified MPR behavior signaling to indicate modified MPR behavior;

or, all or part of reserved bits in the modified MPR behavior signaling, the reserved bits being bits other than the first bit in the modified MPR behavior signaling;

or, a first bit in the modified maximum power reduction, MPR, behavior signaling, and all or part of the reserved bits.

Illustratively, the modified MPR behavior signaling is reported on a frequency band basis. Namely:

for the n41 frequency band, the modified MPR behavior signaling defines the meaning of the lowest 2 bit positions 0 or 1, i.e. the lowest 2 bits are the first bits and the remaining 6 bits are reserved bits.

For the n71 frequency band, the modified MPR behavior signaling defines the meaning of the lowest 1 bit position 0 or 1, i.e. the lowest 1 bit is the first bit and the remaining 7 bits are reserved bits. While other frequency bands are not defined, 8 bits are reserved bits.

In one example, the reporting mode shown in table three below is adopted for reporting:

watch III

Optionally, taking the frequency band n71 as an example, the other bits except the 1 st bit (the first bit) in table three are reserved bits, and 7 reserved bits are adopted for indicating the additional out-of-band radiation requirement supported by the terminal. When the bit value of the reserved bit is the first value, the terminal equipment supports the additional out-of-band radiation requirement corresponding to the bit; and when the bit value of the reserved bit is the second value, the terminal equipment does not support the additional out-of-band radiation requirement corresponding to the bit.

Illustratively, the first value is 1 and the second value is 0. Alternatively, the first value is 0 and the second value is 1.

In another example, the 8 th bit in the modified MPR behavior signaling is used to indicate the type of indication of the current modified MPR behavior signaling. When the value of the 8 th bit is 1 (belonging to the multiplexing indication type), bits 1-7 in the modified MPR behavior signaling are used for indicating the additional out-of-band radiation requirement supported by the terminal; when the value of the 8 th bit is 0 (not belonging to the multiplexing indication type), the 1 st bit in the modified MPR behavior signaling is used for indicating the modified MPR behavior, and the remaining 2 nd to 6 th bits are reserved bits.

In another example, the 8 th bit in the modified MPR behavior signaling is used to indicate the type of indication of the current modified MPR behavior signaling. When the value of the 8 th bit is 1 (belonging to the multiplexing indication type), bits 1-7 in the modified MPR behavior signaling are used for indicating the additional out-of-band radiation requirement supported by the terminal; when the value of the 8 th bit is 0 (not belonging to the multiplexing indication type), the 1 st bit in the modified MPR behavior signaling is used to indicate the modified MPR behavior, and the remaining 2 nd to 6 th bits are used to indicate the additional out-of-band radiation requirement supported by the terminal.

That is, the k bits multiplexed in the third indication information may be all or part of the first bit and the reserved bit in the modified MPR behavior signaling, which is not limited in this embodiment of the application.

Optionally, the modified MPR behavior is carried within RRC signaling, which is part of the UE radio access capability. The modified MPR behavior is contained in RRC signaling in an information element IE named Radio Frequency-Parameter (RF-Parameter) (The IE RF-Parameters used to dependent RF-capabilities for NR operation): RF-Parameters- > BandNR- > modifiedMPR-Behavviour.

In step 704, the network device receives the third indication information from the terminal device.

Optionally, the network device receives third indication information from the terminal device, where there are k multiplexed bits in the third indication information, where the k bits are bits for indicating an additional out-of-band emission requirement supported by the terminal device, and k is a positive integer. Optionally, the network device receives an RRC signaling from the terminal device, where the RRC signaling carries the third indication information.

Optionally, the multiplexed k bits in the third indication information include:

a first bit in the modified MPR behavior signaling, the first bit being a bit in the modified MPR behavior signaling to indicate modified MPR behavior;

or, all or part of reserved bits in the modified MPR behavior signaling, the reserved bits being bits other than the first bit in the modified MPR behavior signaling;

or, a first bit in the modified maximum power reduction, MPR, behavior signaling, and all or part of the reserved bits.

Optionally, the network device determines one or more additional out-of-band emission requirements supported by the terminal device according to the third indication information. The network device configures the terminal device with cells available for access according to one or more additional out-of-band emission requirements supported by the terminal device.

In summary, the method provided in this embodiment indicates the additional out-of-band radiation requirement supported by the terminal device by multiplexing k bits in the already-defined signaling, and does not need to additionally design a new RRC signaling, thereby simplifying the system design of the communication system.

In view of the second embodiment:

fig. 8 shows a flowchart of an information indication method provided by another exemplary embodiment of the present application. The method may be applied in the communication system shown in fig. 3. The method comprises the following steps:

step 802, the network device sends an inquiry request to the terminal device, wherein the inquiry request is used for inquiring an additional out-of-band radiation requirement supported by the terminal device;

optionally, the network device sends an inquiry request to the terminal device before configuring the carrier or the cell to the terminal device.

Step 804, the terminal device receives an inquiry request from the network device;

step 806, the terminal device sends inquiry feedback to the network device, wherein the inquiry feedback comprises indication information;

in one design, the interrogation request carries n first network signaling values, each first network signaling value indicating an additional out-of-band emission requirement; the inquiry feedback carries n feedback information corresponding to the n first network signaling values, and the feedback information is acknowledgement feedback or negative acknowledgement feedback.

As shown in fig. 9, the network device inquires whether the terminal device supports all the first NS signaling values (NS _ a, NS _ b, NS _ c, NS _ d, NS _ X) on the frequency band a, and the terminal device feeds back acknowledgement feedback or negative acknowledgement feedback corresponding to each first NS signaling value to the network device. Illustratively, the acknowledgement feedback is a bit with a value of 1, and the negative acknowledgement feedback is a bit with a value of 0.

In another design, the query request does not carry a second network signaling value, the query feedback carries m second network signaling values, and each second network signaling value is used to indicate an additional out-of-band emission requirement supported by the terminal device.

As shown in fig. 10, the network device inquires of all NS signaling values supported by the terminal device on the frequency band a, and the terminal device feeds back m second NS signaling values supported on the frequency band a, such as (NS _ a, NS _ b, NS _ c, NS _ d, NS _ X), to the network device.

Step 808, the network device receives the query feedback from the terminal device.

Optionally, the network device receives query feedback from the terminal device.

Optionally, the network device determines one or more additional out-of-band emission requirements supported by the terminal device based on the query feedback. The network device configures the terminal device with cells available for access according to one or more additional out-of-band emission requirements supported by the terminal device.

That is, if the terminal device supports the corresponding frequency band and the network signaling value, the network device may continue to perform the configuration of the corresponding carrier; and if not, the network equipment does not carry out the configuration of the corresponding carrier.

In summary, in the method provided in this embodiment, the network device may actively inquire the terminal device about the additional out-of-band radiation requirement supported by the network device, and the terminal device that does not need to configure a carrier or a cell does not need to report, so that the number of signaling that the network device needs to receive is reduced, and air interface resources are saved.

Aiming at the third mode:

fig. 11 shows a flowchart of an information indication method provided by an exemplary embodiment of the present application. The method may be applied in the communication system shown in fig. 3. The method comprises the following steps:

step 1120, when the access of the terminal equipment in the cell fails, the terminal equipment sends failure reason indication information to the network equipment;

in the third method, the network device does not report the network signaling value capability supported by the network device during initial access, and the network device does not query the terminal capability before configuring the secondary cell, so that the situations of failure of secondary cell configuration and the like can potentially occur.

For example, the network device broadcasts an additional outband emission indication NS _ a, NS _ b, NS _ c, NS _ d, NS _ X to the system configuring band a to the terminal, which belongs to the cell of band a. The terminal equipment does not support the NS _ X signaling value broadcasted on the frequency band A, thereby regarding the cell as the access prohibition state.

And the terminal equipment reports a failure reason value which cannot access the cell to the base station, namely, the terminal equipment does not support the additional out-of-band radiation indication NS _ X.

Wherein the failure reason indication information includes a failure reason value, and the failure reason value is used for indicating an additional out-of-band emission requirement which is not supported by the terminal equipment.

Step 1140, the network device receives failure reason indication information from the terminal device;

optionally, the network device receives failure cause indication information from the terminal device.

Optionally, the network device determines one or more additional out-of-band emission requirements that are not supported by the terminal device according to the failure cause value in the failure cause indication information. The network device configures the terminal device with cells for access based on one or more additional out-of-band emission requirements not supported by the terminal device.

In summary, in the method provided in this embodiment, only when the cell access fails, the terminal device reports the failure cause value to the network device, so that the terminal device that does not have the cell access failure does not need to report, the number of signaling that the network device needs to receive is reduced, and the air interface resource is saved.
