Detailed Description

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

Fig. 1 shows a block diagram of a communication system provided by an exemplary embodiment of the present disclosure, which may include: a core network 11, an access network 12 and a terminal 13.

The core network 11 includes a number of core network devices 110. The core network device 110 includes Access and Mobility Management Function (AMF), Session Management Function (SMF), and User Plane Management Function (UPF), where AMF is used to control Access authority and switching of the terminal, and SMF is used to provide server continuity and uninterrupted User experience of the server, such as: internet Protocol (IP) address and anchor point changes, etc.

Several access network devices 120 are included in access network 12. The access network equipment 120 may be a base station, which is a device deployed in an access network to provide wireless communication functions for terminals. 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, names of devices having a base station function may be different, for example, in a Long Term Evolution (LTE) system, the device is called eNodeB or eNB; in a 5G New Radio (NR) system, it is called a gNode B or a gNB. As communication technology evolves, the name "base station" may change. For convenience, in the embodiments of the present disclosure, the above-mentioned device for providing a wireless communication function for a terminal is collectively referred to as an access network device.

The terminal 13 may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem having wireless communication functions, as well as various forms of terminals (UE), Mobile Stations (MS), terminal (terminal device), and the like. For convenience of description, the above-mentioned devices are collectively referred to as a terminal. The access network device 120 and the terminal 13 communicate with each other through some air interface technology, for example, a Uu interface. Industrial sensors (Industrial sensors), video surveillance (video surveillance), wearable devices, and the like based on 5G do not need to support such a large bandwidth, and especially in the Industrial sensors, only several megabytes of transmission bandwidth are required. Such terminals may be classified as a new terminal type in the 5G successor enhancements and corresponding technical feature improvements are made.

Optionally, during the wireless communication between the terminal 13 and the access network device 120, the wireless communication may be performed through an authorized frequency band, or may be performed through an unauthorized frequency band.

In the idle state, the terminal needs to perform paging detection according to the paging occasion period. The following is a brief description of how the terminal implements paging detection:

the access network device configures a plurality of Paging Occasions (PO) and corresponding control Channel resource information in a period of a Synchronization Signal and Physical Broadcast Channel (PBCH) Block (SSB).

The terminal calculates its paging occasion position using information such as the terminal Identifier (ID) according to the formula of R1538.304. When the Paging occasion arrives, the terminal detects Paging Downlink Control Information (Paging DCI) according to the configured Control channel resource Information.

The terminal acquires the paging type according to the content of the DCI, and if the paging type is the paging message scheduling type, demodulates the corresponding Physical Downlink Shared Channel (PDSCH) message (the resource also has an indication in the DCI).

And after demodulating the PDSCH message, the terminal checks the ID of the terminal, and if the terminal does not have the ID of the terminal, the terminal continues waiting for the next paging occasion and repeats the process. However, the above paging detection process needs to consume more electric energy, which raises the power consumption of the terminal.

In the related art, in the Paging process of the UE, a change condition of a time-frequency synchronization Reference Signal (TRS) may be indicated by Paging Downlink Control Information (Paging DCI), or a change condition of the TRS may be indicated by a System message (SIB).

However, there are corresponding problems with both the Paging DCI indication and the SIB indication.

1. If the TRS on/off change frequency is low, the change condition of the TRS is indicated by using Paging DCI, the resource utilization rate of the DCI indication information is wasted, and the indication efficiency is low; however, the UE cannot determine whether to obtain the indication through the SIB, and if the high-level configuration is indicated only through the SIB, the SIB is indicated at a cell level, so that the change speed is slow, and the flexibility is insufficient.

2. If the frequency of TRS on/off change is high, when there is no Paging Message (Paging Message) corresponding to the UE in a certain PO, the base station further needs to send an additional Paging DCI for indication, and the priority of TRS on/off change is low, so that compared with the importance of sending a system information update/short Message (short Message) in the Paging DCI, sending an additional Paging DCI to indicate the TRS on/off change is definitely wasteful of system resources.

The communication system and the service scenario described in the embodiment of the present disclosure are for more clearly illustrating the technical solution of the embodiment of the present disclosure, and do not constitute a limitation to the technical solution provided in the embodiment of the present disclosure, and as a person having ordinary skill in the art knows that along with the evolution of the communication system and the appearance of a new service scenario, the technical solution provided in the embodiment of the present disclosure is also applicable to similar technical problems.

Fig. 2 is a flowchart of a power saving method according to an exemplary embodiment of the present disclosure, which is described by taking the method as an example when the method is applied to an access network device, and as shown in fig. 2, the method includes:

step 201, sending configuration information to the terminal, where the configuration information is used to configure the terminal with the relevant configuration of the time frequency synchronization reference signal TRS.

In some embodiments, the configuration information is sent to the terminal in an idle state.

The frequencies of the access network device and the physical crystal oscillator of the terminal have small deviation and cannot be completely consistent, so that the radio frequency carrier signal received by the terminal has deviation on phase, and the received modulation symbol deviates from a certain phase angle on a schematic diagram of the demodulation symbol of the received subcarrier, which is caused by the accumulation of frequency deviation on time. At this time, the TRS signal is required to track the rotational phase of the other data signals.

In some embodiments, the manner of acquiring the TRS validation information includes at least one of acquiring from a system message SIB, and reading from physical layer information. Since the system message SIB is a cell-level message, when the TRS validation information is configured in the SIB, the TRS validation information needs to be acquired and configured for all UEs in the cell, so that the SIB is sent to the UEs, and the updating speed is slow; the physical layer information indicates that the resources are limited, and the TRS effective information is transmitted through the physical layer information, so that the resources are wasted. When the SIB and the physical layer information simultaneously transmit the TRS validation information, the different TRS validation information indicated by the SIB and the physical layer information is likely to be caused due to the difference in time consumption of data processing, so that the TRS validation information cannot be accurately indicated.

The related configuration includes an acquisition mode of the TRS validation information corresponding to the terminal. Optionally, the configuration information is used to indicate, when the terminal is in an idle state, a manner in which the terminal acquires the TRS validation information.

In the embodiment of the present disclosure, the configuration information is used to indicate a manner for the terminal to obtain the TRS validation information, for example: acquiring TRS effective information through SIB; or, acquiring the TRS validation information through the physical layer information.

In some embodiments, the configuration information includes a first indication field, where the first indication field is used to indicate a manner in which the terminal acquires the TRS validation information.

Optionally, the first indication field occupies one bit; alternatively, the first indication field occupies a plurality (two or more) of bits; alternatively, the first indication field is formed by a combination of a plurality of bit code points.

And the access network equipment determines the value of the first indication field based on the change frequency of the TRS effective information corresponding to the terminal.

In some embodiments, in response to that the change frequency of the TRS validation information corresponding to the terminal is lower than (or equal to) the frequency threshold, determining that a first indication field corresponds to a first value, where the first value is used to indicate the terminal to read the TRS validation information from the physical layer information, that is, the first value corresponds to an acquisition mode of reading the TRS validation information from the physical layer information; and in response to that the change frequency of the TRS validation information corresponding to the terminal reaches (is greater than or equal to) the frequency threshold, determining a second value corresponding to the first indication field, where the second value is used to indicate the terminal to read the TRS validation information from the system message SIB, that is, the second value corresponds to an acquisition mode for reading the TRS validation information without reading the TRS validation information from the physical layer information, and the TRS validation mode is directly understood according to the TRS validation information configured by the SIB.

It should be noted that the first value corresponds to the physical layer information, and the second value corresponds to the SIB only by way of illustrative example, and the embodiment of the present disclosure may also be implemented such that the first value corresponds to the SIB and the second value corresponds to the physical layer information, which is not limited in the embodiment of the present disclosure.

Illustratively, in response to that the value corresponding to the first indication field is 1, the terminal is indicated to read the TRS valid information from the SIB; and in response to that the corresponding value of the first indication field is 0, indicating the terminal to read the TRS effective information from the physical layer information.

When the first indication field is formed by combining multi-bit code points, and when the multi-bit code points form a first combination mode, the first indication field is used for indicating the terminal to read TRS effective information from an SIB; the first indication field is used for indicating the terminal to read the TRS validation information from the physical layer information in response to the multi-bit code point constituting the second combined mode.

Illustratively, when the multi-bit code point corresponding to the first indication field constitutes 1011, the terminal is instructed to read the TRS validation information from the SIB, and when the multi-bit code point corresponding to the first indication field constitutes 0110, the terminal is instructed to read the TRS validation information from the physical layer information.

Optionally, the configuration information is implemented as a Paging Early Indication (PEI) sequence; or, the configuration information is implemented as PEI physical layer information indicated in advance by paging.

When the configuration information is realized as a PEI sequence, the information carried by the PEI sequence is limited, and the first indication field occupies 1 bit; when the configuration information is implemented as PEI physical layer information, such as: when the PEI DCI is configured, the first indication field may occupy 1 bit, may also occupy multiple bits, and may also be formed by combining multiple bit code points.

That is, in the embodiment of the present application, a switch is added to the PEI for indicating the TRS available information obtaining manner corresponding to the terminal. Illustratively, when the first indication field is 0, the switch is in an on state, and the TRS available information is correspondingly analyzed from the Paging DCI, and when the first indication field is 0, the switch is in an off state, and the terminal does not need to analyze the TRS available information from the Paging DCI, and directly understands the effective SIB configuration.

In some embodiments, when the configuration information is implemented as PEI physical layer information, a second indication field is further included in the configuration information, and the second indication field is used to indicate the configuration of the TRS validation information.

And after the access network equipment acquires the configuration information, the configuration information is sent to the UE, and the UE acquires the TRS effective information based on the configuration information.

To sum up, in the method provided in the embodiment of the present disclosure, by introducing the switch in the PEI, the manner in which the UE parses the TRS available information is indicated, so that resource waste caused by only indicating the TRS change condition through the Paging DCI is avoided, and the problem of low flexibility caused by only indicating the TRS change condition through the SIB is avoided, thereby improving the indication flexibility and resource utilization rate of the TRS valid information, and achieving the effect of saving power.

Fig. 3 is a flowchart of a power saving method according to an exemplary embodiment of the present disclosure, which is described by taking the method as an example for being applied to a terminal, and as shown in fig. 3, the method includes:

step 301, receiving configuration information sent by an access network device, where the configuration information is used to configure a relevant configuration of a time frequency synchronization reference signal TRS.

Optionally, the current terminal is a terminal in an idle state, that is, when the terminal is in the idle state, the configuration information sent by the access network device is received.

In the embodiment of the present disclosure, the configuration information is used to indicate a manner for the terminal to obtain the TRS validation information, for example: acquiring TRS effective information through SIB; or, acquiring the TRS validation information through the physical layer information.

In some embodiments, the configuration information includes a first indication field, where the first indication field is used to indicate a manner in which the terminal acquires the TRS validation information.

Optionally, the first indication field occupies one bit; alternatively, the first indication field occupies a plurality (two or more) of bits; alternatively, the first indication field is formed by a combination of a plurality of bit code points.

And the terminal reads the first indication field from the configuration information and determines a way of acquiring the TRS effective information according to the first indication field.

In some embodiments, in response to that the change frequency of the TRS validation information corresponding to the terminal is lower than (or equal to) a frequency threshold, determining that a first indication field corresponds to a first value, where the first value is used for indicating the terminal to read the TRS validation information from physical layer information; and in response to that the change frequency of the TRS effective information corresponding to the terminal reaches (is greater than or equal to) the frequency threshold, determining that the first indication field corresponds to a second value, wherein the second value is used for indicating the terminal to read the TRS effective information from the system message SIB.

That is, a first indication field is read from the configuration information, and the first indication field is used for indicating a manner of acquiring the TRS validation information.

Optionally, the configuration information is implemented as a PEI sequence; or, the configuration information is implemented as PEI physical layer information.

When the configuration information is realized as a PEI sequence, the information carried by the PEI sequence is limited, and the first indication field occupies 1 bit; when the configuration information is implemented as PEI physical layer information, such as: when the PEI DCI is configured, the first indication field may occupy 1 bit, may also occupy multiple bits, and may also be formed by combining multiple bit code points.

Step 302, acquiring TRS validation information based on the configuration information.

In some embodiments, the TRS validation information includes a validation location of the terminal corresponding to your TRS signal. That is, TRS available information corresponding to the terminal.

In some embodiments, after acquiring the TRS validation information, the terminal tracks the rotation phase of the data signal according to the TRS validation information, and performs time-frequency synchronization.

To sum up, in the method provided in the embodiment of the present disclosure, by introducing the switch in the PEI, the manner in which the UE parses the TRS available information is indicated, so that resource waste caused by only indicating the TRS change condition through the Paging DCI is avoided, and the problem of low flexibility caused by only indicating the TRS change condition through the SIB is avoided, thereby improving the indication flexibility and resource utilization rate of the TRS valid information, and achieving the effect of saving power.

Fig. 4 is a flowchart of a power saving method provided in another exemplary embodiment of the present disclosure, which is applied to a terminal and an access network device as an example, and includes:

step 401, the access network device sends configuration information to the terminal.

The configuration information is used for configuring the relevant configuration of the time frequency synchronization reference signal TRS to the terminal.

The related configuration includes an acquisition mode of the TRS validation information corresponding to the terminal.

In the embodiment of the present disclosure, the configuration information is used to indicate a manner for the terminal to obtain the TRS validation information, for example: acquiring TRS effective information through SIB; or, acquiring the TRS validation information through the physical layer information.

In some embodiments, the configuration information includes a first indication field, where the first indication field is used to indicate a manner in which the terminal acquires the TRS validation information.

Optionally, the first indication field occupies one bit; alternatively, the first indication field occupies a plurality (two or more) of bits; alternatively, the first indication field is formed by a combination of a plurality of bit code points.

And the access network equipment determines the value of the first indication field based on the change frequency of the TRS effective information corresponding to the terminal.

In some embodiments, in response to that the change frequency of the TRS validation information corresponding to the terminal is lower than (or equal to) the frequency threshold, determining that a first indication field corresponds to a first value, where the first value is used to indicate the terminal to read the TRS validation information from the physical layer information, that is, the first value corresponds to an acquisition mode of reading the TRS validation information from the physical layer information; and in response to that the change frequency of the TRS validation information corresponding to the terminal reaches (is greater than or equal to) the frequency threshold, determining a second value corresponding to the first indication field, where the second value is used to indicate the terminal to read the TRS validation information from the system message SIB, that is, the second value corresponds to an acquisition mode for reading the TRS validation information without reading the TRS validation information from the physical layer information, and the TRS validation mode is directly understood according to the TRS validation information configured by the SIB.

Optionally, the configuration information is implemented as a Paging Early Indication (PEI) sequence; or, the configuration information is implemented as PEI physical layer information indicated in advance by paging.

When the configuration information is realized as a PEI sequence, the information carried by the PEI sequence is limited, and the first indication field occupies 1 bit; when the configuration information is implemented as PEI physical layer information, such as: when the PEI DCI is configured, the first indication field may occupy 1 bit, may also occupy multiple bits, and may also be formed by combining multiple bit code points. In some embodiments, when the configuration information is implemented as PEI physical layer information, a second indication field is further included in the configuration information, and the second indication field is used to indicate the configuration of the TRS validation information.

Step 402, the terminal receives configuration information sent by the access network device.

Optionally, after receiving the configuration information sent by the access network device, the terminal reads the first indication field from the configuration information, and determines a corresponding manner of acquiring the TRS validation information according to a value of the first indication field.

And the terminal reads the first indication field according to the indication mode of the pre-configured indication field.

In step 403, the terminal acquires the TRS validation information based on the configuration information.

In some embodiments, the TRS validation information indicates a TRS validation location corresponding to the terminal in a paging cycle.

To sum up, in the method provided in the embodiment of the present disclosure, by introducing the switch in the PEI, the manner in which the UE parses the TRS available information is indicated, so that resource waste caused by only indicating the TRS change condition through the Paging DCI is avoided, and the problem of low flexibility caused by only indicating the TRS change condition through the SIB is avoided, thereby improving the indication flexibility and resource utilization rate of the TRS valid information, and achieving the effect of saving power.
