Description

Cell measurement method, message sending method, device, equipment and storage medium

technical field

The present application relates to the field of mobile communication, and in particular to a cell measurement method, a message sending method, a device, a device and a storage medium.

Background technique

A terminal device in an idle (IDLE) state and an inactive (INACTIVE) state will, if necessary, measure the signal quality of the neighboring cell of its serving cell, so that the terminal device will always stay in the network signal in a better neighborhood. However, the signal quality measurement for neighboring cells will lead to high energy consumption of the terminal equipment.

In the fifth generation mobile communication technology (5th Generation Mobile Communication Technology, 5G), an energy-saving technology for terminal equipment is proposed. Specifically, a non-cell-edge (not-cell-edge) criterion and a low-mobility (low-mobility) criterion are defined. The terminal device performs measurement relaxation of radio resource management (Radio Resource Management, RRM) of neighboring cells by judging whether it satisfies the non-cell edge criterion and/or the low mobility criterion, so as to realize energy saving. Wherein, the non-cell-edge criterion corresponds to a non-cell-edge criterion parameter, that is, a non-cell-edge criterion threshold. The terminal device can judge whether it satisfies the non-cell-edge criterion according to the signal quality measurement result of its serving cell and the non-cell-edge criterion threshold. Satisfying the low mobility criterion means that when the signal quality measurement result of the serving cell of the terminal device changes little, it means that the terminal device does not need to perform cell reselection, so the RRM measurement relaxation of neighboring cells can be performed.

The network device broadcasts a set of non-cell-edge criterion parameters to the terminal device, so that the terminal device judges whether to perform RRM measurement relaxation of neighboring cells. However, different terminal devices have different uplink coverage capabilities. For the setting of non-cell edge criterion parameters, further discussion and research are needed.

Depending on the context, the word "if" as used herein may be interpreted as "at" or "when" or "in response to a determination."

First, the relevant technical background involved in the embodiment of the present application is introduced:

Introduce the radio resource control state:

With the continuous improvement of the speed, delay, high-speed mobility, and energy efficiency of mobile communication networks, as well as the diversity and complexity of services in future life, the 3rd Generation Partnership Project (3GPP) international standards organization Started the research and development of 5G. The main application scenarios of 5G include: Enhanced Mobile Broadband (eMBB), Ultra Reliable Low Latency Communications (URLLC), and massive Machine Type of Communication (mMTC).

New air interface (New Radio, NR) can be deployed independently. In the 5G network environment, in order to achieve the purpose of reducing air interface signaling, quickly restoring wireless connections, and quickly restoring data services, a new Radio Resource Control (RRC) state is defined, specifically RRC_INACTIVE state, which is different from the RRC idle (RRC_IDLE) state and the RRC active (RRC_ACTIVE) state. Wherein, each RRC state can reflect a network connection state, and describes how the network device and the terminal handle terminal movement, paging message and system information broadcast.

RRC_IDLE: Mobility in the RRC_IDLE state refers to terminal-based cell selection reselection. The paging is initiated by the core network (Core Network, CN) device, and the paging area is configured by the CN device. The base station does not have a terminal access stratum (Access Stratum, AS) context. There is no RRC connection.

RRC_CONNECTED: There is an RRC connection in the RRC_IDLE state, and the base station and the terminal have a terminal AS context. The location of the terminal determined by the network device is at the cell level. Mobility refers to mobility controlled by network devices. Unicast data can be transmitted between the terminal and the base station.

RRC_INACTIVE: Mobility in the RRC_IDLE state refers to cell selection and reselection based on the terminal, there is a connection between CN and NR, the terminal AS context exists on a base station, and paging is triggered by the radio access network (Random Access Network, RAN) , the RAN-based paging area is managed by the RAN, and the location of the terminal determined by the network device is based on the paging area level of the RAN.

Introduce the supplementary uplink carrier:

A supplementary uplink carrier (Supplementary Uplink, SUL) may also be called a supplementary uplink. Usually, a cell (Cell) generally includes an uplink carrier (Uplink Carrier) and a downlink carrier (Downlink Carrier), and the uplink carrier and the downlink carrier are in the same frequency band (Frequency Band). However, in the 5G system, the frequency points of the frequency bands used are relatively high, such as millimeter waves. The higher the frequency band, the greater the signal transmission loss. Since the transmit power of the terminal equipment is limited, this will lead to the limitation of the uplink coverage of the terminal equipment. Therefore, the 5G system introduces SUL technology to ensure the uplink coverage of terminal equipment by providing a supplementary uplink, which is generally in a low frequency band, such as the Long Term Evolution (LTE) frequency band. The normal uplink of the terminal equipment is called uplink (Uplink, UL) or normal uplink (Normal Uplink, NUL) NUL. SUL adopts lower frequency bands and lower frequency points, so the signal loss is small, which can ensure the coverage of UL. It should be noted that the downlink (Downlink, DL), UL and SUL belong to the same cell, and the terminal device can dynamically select the transmission link between UL and SUL, but at a time of use, the terminal device can only select one of them. One transmission, cannot transmit uplink on two uplinks at the same time.

Introduce the uplink coverage enhancement of NR:

The coverage of the mobile communication network is one of the main network performances concerned by operators. Compared with LTE, 5G works in a higher frequency band. For example: for frequency range 1 (Frequency Rang 1, FR1), the working frequency band is 3.5GHz; for frequency range 2 (Frequency Rang 2, FR2), the working frequency band may be as high as 28GHz or 39GHz. The higher the operating frequency band, the greater the path loss experienced by the signal, resulting in reduced network coverage. Usually, the transmission power of the network equipment is much greater than that of the terminal equipment, so the uplink coverage of the network faces a more serious coverage limitation problem. Uplink coverage enhancement is currently being standardized in NR. One of the aspects is to introduce repetition (repetition) transmission for the Physical Uplink Shared Channel (PUSCH) transmission of Message 3 (Message 3, Msg3) in the random access process to achieve Purpose of enhanced Msg3 coverage. The terminal device can judge whether to perform repeated transmission according to the downlink coverage situation. For example, when the measured value of Reference Signal Receiving Power (RSRP) is lower than a pre-configured threshold, the terminal device can pass Message 1 (Message 1, Msg1) requests the repeated transmission of PUSCH of Msg3. After the network device receives the specific Msg1, it can allocate an uplink grant (UL grant) to the terminal device through the uplink grant (UL grant) in the Random Access Response (Random Access Response, RAR) in Message 2 (Message 2, Msg2). Enhanced Msg3 resource for repeated transmissions.

Introducing neighborhood reselection:

Cell Reselection means that the terminal device selects and accesses a signal by monitoring the currently accessed cell (also called the serving cell) and the signal quality of the adjacent cell of the currently accessed cell in idle mode. The best neighborhood in the process.

When the signal quality and level of the adjacent cell meet the S(Srxlev) criterion and a certain reselection decision criterion (R criterion), the terminal device will access the adjacent cell to camp on. The reselection decision criteria include that in the process of cell selection and reselection, the terminal device will use a cell reselection strategy based on frequency point priority (the priority of the frequency point corresponding to the cell) in order to meet the load balance in idle mode. District re-election.

After the terminal equipment camps in a certain cell, it will continue to measure the cell. The radio resource control (Radio Resource Control, RRC) layer will calculate the S value according to the measurement result of the reference signal received power RSRP, and compare it with the same frequency measurement start threshold (Sintrasearch) and the different frequency/different system measurement start threshold (Snonintrasearch ) for comparison, as a criterion for determining whether the terminal equipment starts the signal quality measurement of the adjacent cell. Among them, the S value is the S criterion in the cell selection, the formula: Srxlev=Qrxlevmeas–(qRxLevMin+qRxLevMinOffset)–pCompensation, the S criterion=the RSRP value of the measured cell–{the lowest receiving level (usually 0-128dbm)+the lowest Receive level offset (usually 0)} - power offset (usually 0).

Afterwards, the relevant content of the cell reselection process is introduced:

·Measurement configuration

The network device will configure the radio resource management (Radio Resource Management) measurement timing configuration based on the synchronization signal block (Synchronization Signal Block) of each frequency point (per frequency) for the intra-frequency (Intra-frequency) and inter-frequency (Inter-frequency). (SSB-based RRM Measurement Timing Configuration, SMTC), to assist terminal equipment to perform signal measurement, to achieve the purpose of terminal equipment power saving.

· Cell signal quality acquisition

The system broadcasts the parameter N and threshold of per frequency to select the best beam (beam);

The terminal device will linearly average the signal quality of the best top N beams that meet the threshold;

If the parameter N and the threshold of the per frequency are not broadcast, the signal quality of the best beam in the cell is the cell signal quality.

·Target cell selection (R criterion)

The candidate cell is controlled by the optimal cell range (rangeToBestCell). Specifically, among all the candidate cells within the rangeToBestCell range in which the signal quality of the best cell (the best signal quality) is different from that of the best cell (the best signal quality), the terminal device selects the one with the most beams that meet the threshold. cell as the target cell.

·Frequency priority

In order to achieve the load balancing purpose of different frequency points, the priority of different frequency points can be set on the network side. Terminal equipment preferentially resides on high-priority frequency points. The frequency point priority can be obtained from system broadcasts, or from dedicated signaling, such as RRC release (RRRelease) messages, or inherited from other radio access technologies (Radio Access Technology, RAT).

·Priority configuration

At the same time, the cell reselection priority (Cell Reselection Priority) and the sub-priority (sub-priority) are used to jointly indicate the frequency priority of the final cell reselection. Among them, the value of Cell Reselection Priority is 0 to 7, and the value of sub-priority is {0.2, 0.4, 0.6, 0.8}, which can indicate 40 frequency priorities in total. Among them, sub-priority is only used for NR frequency and LTE frequency.

· Dedicated priority configuration release conditions

Including state transition of terminal equipment, public land mobile communication network (Pub1ic Land Mobile Network, PLMN) selection, timer timeout triggering special priority configuration.

·Priority use

If the terminal device has a dedicated configuration, it will not use the broadcast configuration;

When the terminal device is in any cell state, use broadcast configuration;

If no priority is configured, the default is the lowest;

Frequencies between RATs will not be configured with the same frequency priority.

The adjacent cell measurement of the terminal equipment in the IDLE and INACTIVE states starts

All relevant parameters of measurement behavior constraints of terminal equipment in IDLE and INACTIVE states come from system broadcast messages. The following assumes that all relevant parameters are configured. If there is no configuration, the associated constraints do not exist.

(1) For the start of intra-frequency measurement, when Srxlev>S _IntraSearchP of the serving cell, and Squal>S _IntraSearchQ of the serving cell, the terminal device does not start the same-frequency adjacent cell measurement, otherwise it starts the same-frequency adjacent cell measurement.

(2) For the inter-frequency measurement of the same priority or low priority, when the Srxlev of the serving cell>S _IntraSearchP , and the Squal>S _IntraSearchQ of the serving cell, the terminal device does not start the inter-frequency measurement of the same priority or low priority measured, otherwise activated.

(3) For high-priority inter-frequency measurement, the terminal device always starts its measurement.

· Cell reselection behavior based on the measurement results of neighboring cells

(1) For cells with the same frequency and different frequencies with the same priority to perform cell reselection, the R criterion (sorted according to RSRP) needs to be met, the signal quality of the new cell is better than that of the current cell and lasts for a specified period of time, and the terminal equipment stays on The time in the original cell shall not be shorter than 1s.

(2) For reselection of a high-priority cell, the signal quality of the high-priority cell needs to be higher than a certain threshold and last for a specified period of time, and the terminal device stays in the original cell for no less than 1 second.

(3) For low-priority cells to perform reselection, it is necessary to have no high priority, cells with the same priority meet the requirements, the signal quality of the original cell is lower than a certain threshold, and the signal quality of low-priority cells is higher than a certain threshold and lasts for a certain period of time length, the terminal equipment stays in the original cell for no less than 1s.

Introduce neighborhood measure relaxation:

The 5G system introduces energy-saving technology, in which two criteria are defined for the RRM measurement of terminal equipment in the IDLE state and INACTIVE state, namely the not-cell-edge criterion and the low-mobility criterion. When two criteria are configured at the same time, the network device further instructs the terminal device whether the two criteria are "and" or "or". The not-cell-edge criterion mainly defines the RSRP/Reference Signal Receiving Quality (RSRQ) threshold. Specifically, the network device defines two thresholds s-SearchThresholdP and s-SearchThresholdQ of the not-cell-edge criterion by configuring CellEdgeEvaluation (s-SearchThresholdQ is optional configuration), when the RSRP measurement of the serving cell When the value is greater than s-SearchThresholdP and the RSRQ measurement value is greater than s-SearchThresholdQ (in the case of network equipment configured with s-SearchThresholdQ), the terminal device meets the not-cell-edge criterion, and the RRM measurement of neighboring cells can be relaxed. The Low-mobility criterion means that when the RSRP of the serving cell changes little, it means that the terminal has little need for cell reselection, so the neighbor cell measurement can be relaxed to achieve the purpose of energy saving of the terminal equipment.

In the related art, in order to control the terminal equipment to relax the measurement of neighboring cells, the network equipment will configure a set of not-cell-edge criteria, that is, a set of s-SearchThresholdP and s-SearchThresholdQ parameters. Since the uplink coverage of SUL and NUL is different, the network coverage of uplink and downlink connections and service transmission that can be performed by terminal equipment supporting SUL and NUL is different. In order to take into account the terminal equipment that only supports NUL, the threshold value of s-SearchThresholdP needs to be configured larger, which brings negative impact on the terminal equipment that supports SUL. Because for SUL terminal equipment, the network coverage is large, and the measurement of neighboring cells can only be relaxed when the RSRP value of the serving cell is large, which will not be conducive to energy saving of terminal equipment. If the threshold value of s-SearchThresholdP is set to be small, it can meet the energy saving requirements of SUL terminal equipment, but for terminal equipment that only supports NUL, it will cause the terminal equipment to still perform the measurement of neighboring cells when it is close to the edge of the cell. , which will lead to too late discovery of neighboring cells, and may not be able to find the target cell for cell reselection in time, resulting in no available cell access for such terminal equipment for a period of time. The problems faced by terminals supporting uplink coverage enhancement (Coverage Enhancement, CE) capabilities are similar to those of terminal devices supporting SUL capabilities. Therefore, for the setting of the not-cell-edge criterion parameters, further research is needed.

Fig. 1 shows a schematic diagram of a system architecture of a communication system provided by an embodiment of the present application. The system architecture may include: a terminal device 10 , an access network device 20 and a core network device 30 .

For convenience of description, the devices mentioned above are collectively referred to as terminal devices. The number of terminal devices 10 is generally multiple, and one or more terminal devices 10 may be distributed in a cell managed by each access network device 20 .

The access network device 20 is a device deployed in an access network to provide a wireless communication function for the terminal device 10 . The access network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, and so on. In systems using different wireless access technologies, the names of devices with access network device functions may be different. For example, in 5G NR systems, they are called gNodeB or gNB. With the evolution of communication technology, the name "access network equipment" may change. For the convenience of description, in the embodiment of the present application, the above-mentioned devices that provide the wireless communication function for the terminal device 10 are collectively referred to as access network devices. Optionally, a communication relationship may be established between the terminal device 10 and the core network device 30 through the access network device 20 . Exemplarily, in the LTE system, the access network device 20 may be EUTRAN (Evolved Universal Terrestrial Radio Access Network, Evolved Universal Terrestrial Radio Network) or one or more eNodeBs in EUTRAN; in the 5G NR system, the access The network device 20 may be the RAN or one or more gNBs in the RAN.

The functions of the core network device 30 are mainly to provide user connections, manage users, and carry out services, and provide an interface to external networks as a bearer network.

The access network device 20 and the core network device 30 may be collectively referred to as network devices.

The access network device 20 and the terminal device 10 communicate with each other through a certain air technology, such as a Uu interface.

Fig. 2 shows a flowchart of a cell measurement method provided by an embodiment of the present application. FIG. 2 illustrates an example in which the method is applied to a terminal device in the communication system shown in FIG. 1 . The method includes:

Step 202: Receive at least two sets of non-cell edge criterion parameters configured by the network device.

The non-cell-edge (not-cell-edge) criterion parameter is used for the terminal equipment to determine whether to perform RRM measurement relaxation of neighboring cells. Optionally, each set of non-cell-edge criterion parameters includes one non-cell-edge criterion threshold, or two non-cell-edge criterion thresholds. In the case where a set of non-cell-edge criterion parameters includes two non-cell-edge criterion thresholds, one threshold is used by the terminal device to compare it with the RSRP of the signal quality measurement result of the serving cell, and the other threshold is used by the terminal device to compare It is compared with the RSRQ of the signal quality measurement result of the serving cell, so that the terminal device can judge whether to perform RRM measurement relaxation of the neighboring cell. For example, the non-cell edge criterion parameters include threshold s-SearchThresholdP and threshold s-SearchThresholdQ. Among them, s-SearchThresholdP is used to compare with RSRP, and s-SearchThresholdQ is used to compare with RSRQ. s-SearchThresholdQ is an optional threshold. The network device broadcasts the system message to the terminal device, so that the terminal device acquires the at least two sets of non-cell edge criterion parameters.

Different terminal devices can support the same or different device capabilities. Optionally, the device capability refers to the capability of the terminal device to support uplink coverage, and the device capability includes at least one of the following:

NUL;

SUL;

· Normal uplink coverage;

·Enhanced uplink coverage.

The terminal device can improve the uplink coverage of the mobile communication network by supporting at least one of SUL and enhanced uplink coverage. Wherein, the terminal device supporting SUL means that the terminal device supports a supplementary uplink carrier (supplementary uplink), and the supplementary uplink carrier is different from NUL (or UL), and is set separately. For example, the supplementary uplink carrier is an uplink carrier configured based on the LTE frequency band. Since the SUL uses a lower frequency band and a lower frequency point, the signal loss is small, which can ensure the coverage of the uplink carrier. The enhanced uplink coverage of the terminal device means that the terminal device supports the repeated transmission of the PUSCH of the Msg3 requested by the terminal device through the Msg1, so as to realize the repeated transmission of the Msg3 to improve the uplink coverage of the mobile communication network. For different terminal devices, the supported device capabilities are different. For example, the terminal device can only support one of SUL and enhanced uplink coverage but not the other, or support both SUL to enhance uplink coverage, or not support SUL and enhanced uplink coverage.

Optionally, for different device capabilities supported by the terminal device, the network device may send different non-cell edge criterion parameters to it. For example, the at least two sets of non-cell-edge criterion parameters include at least two of the following parameters:

· The first non-cell-edge criterion threshold related to NUL;

A second non-cell-edge criterion threshold related to SUL;

The third non-cell-edge criterion threshold related to normal uplink coverage;

The fourth non-cell edge criterion threshold related to enhanced uplink coverage;

The fifth non-cell edge criterion threshold related to the uplink coverage on the NUL;

• The sixth non-cell-edge criterion threshold related to the uplink coverage on the SUL.

Optionally, the first non-cell-edge criterion threshold is set for terminal devices that only support NUL. The second non-cell edge criterion threshold is set for the terminal equipment supporting SUL. The third non-cell edge criterion threshold is set for terminal devices that only support normal uplink coverage. Only supporting normal uplink coverage means that the terminal device does not support repeated transmission of Msg3 during the random access process, and only supports single Msg3 transfers. The fourth non-cell edge criterion threshold is set for a terminal device that supports enhanced uplink coverage (supports repeated transmission of Msg3). The fifth non-cell edge criterion threshold is set for a terminal device that supports NUL but supports or does not support enhanced uplink coverage. The sixth non-cell edge criterion threshold is set for a terminal device that supports SUL but supports or does not support enhanced uplink coverage.

Optionally, the fifth non-cell-edge criterion threshold can also include the seventh non-cell-edge criterion threshold related to normal uplink coverage on NUL, and the eighth non-cell-edge criterion threshold related to enhanced uplink coverage on NUL. at least one. The sixth non-cell-edge criterion threshold can also include at least one of the ninth non-cell-edge criterion threshold related to normal uplink coverage on the SUL and the tenth non-cell-edge criterion threshold related to enhanced uplink coverage on the SUL.

It should be noted that the first non-cell-edge criterion threshold is greater than the second non-cell-edge criterion threshold. The third non-cell-edge criterion threshold is greater than the fourth non-cell-edge criterion threshold. The seventh non-cell-edge criterion threshold is greater than the eighth non-cell-edge criterion threshold. The ninth non-cell-edge criterion threshold is greater than the tenth non-cell-edge criterion threshold.

For terminal devices supporting different device capabilities, the network device will send the same or different non-cell edge criterion parameters to them. For example, all the above non-cell edge criterion parameters are sent to the terminal device. Alternatively, a part is selected from the above non-cell edge criterion parameters and sent to the terminal device. Or, send the non-cell-edge criterion parameter to the terminal device according to the device capability supported by the terminal device.

Step 204: Determine whether to perform RRM measurement relaxation of neighboring cells based on the device capability supported by the terminal device and the non-cell-edge criterion parameter.

When the terminal device receives the non-cell-edge criterion parameter and needs to determine whether to perform the RRM measurement relaxation of the neighboring cell, since the non-cell-edge criterion parameters corresponding to at least two device capabilities are different, the terminal device will base on the device capability supported by the terminal device, Target non-cell-edge criterion parameters are determined among at least two sets of non-cell-edge criterion parameters. For example, the terminal device determines the target non-cell edge criterion parameter according to whether it supports SUL, whether it supports enhanced uplink coverage, and whether it supports SUL and whether it supports enhanced uplink coverage. Afterwards, based on the target non-cell-edge criterion parameters, combined with the signal quality measurement results of the serving cell, it can be judged whether to perform RRM measurement relaxation of the neighboring cell. During this process, in response to the terminal device meeting the requirements of the target non-cell-edge criterion parameter, the terminal device will perform RRM measurement relaxation of neighboring cells. In response to the terminal device not meeting the requirements of the target non-cell-edge criterion parameter, the terminal device does not perform RRM measurement relaxation of the neighbor cell.

Exemplarily, if the target non-cell edge criterion parameters used by the terminal device include the threshold set for RSRP and the threshold set for RSRQ, the RSRP of the signal quality measurement result of the serving cell needs to be greater than the corresponding threshold, and the signal quality of the serving cell Only when the RSRQ of the measurement result is greater than its corresponding threshold, the terminal device will determine to perform RRM measurement relaxation of the neighboring cell. If the non-cell-edge criterion parameters used by the terminal device only include a threshold set for RSRP, and the RSRP of the signal quality measurement result of the serving cell is greater than the threshold, the terminal device will determine to perform RRM measurement relaxation of neighboring cells.

If the terminal device determines that it does not perform the RRM measurement relaxation of the neighboring cell, the terminal device will perform the RRM measurement of the neighboring cell in a normal measurement manner. The normal measurement mode is a measurement mode in which the RRM measurement of the neighbor cell is not performed in a relaxed measurement mode.

To sum up, in the method provided by this embodiment, the network device sends at least two sets of non-cell-edge criterion parameters to the terminal equipment, and at least two sets of non-cell-edge criterion parameters can be set independently for terminal equipment that supports different device capabilities. The non-cell edge criterion parameter of . Targeted and accurate setting of non-cell edge criterion parameters can be achieved, so that terminal devices supporting different device capabilities can realize energy saving based on measurement relaxation during the process of neighbor cell measurement, and can also avoid the occurrence of adjacent cell The measurement is not timely, which leads to the problem that the neighboring cells are found too late.

The network device can send different non-cell-edge criterion thresholds to the terminal device, so that the terminal device can determine the non-cell-edge criterion threshold it uses according to its supported device capabilities, so as to determine whether to perform RRM measurement relaxation of neighboring cells. Specifically include the following three situations:

The first type: for the case of whether the terminal equipment supports SUL.

Fig. 4 shows a flowchart of a cell measurement method provided by an embodiment of the present application. FIG. 4 exemplifies the application of the method to the communication system shown in FIG. 1 . The method includes:

Step 402: The network device sends the first non-cell-edge criterion threshold and the second non-cell-edge criterion threshold to the terminal device.

The network device broadcasts at least two sets of non-cell edge criterion parameters to the terminal device based on the system message. The at least two sets of non-cell-edge criterion parameters include a first non-cell-edge criterion threshold and a second non-cell-edge criterion threshold. Wherein, the first non-cell-edge criterion threshold is a non-cell-edge criterion threshold related to NUL, and the second non-cell-edge criterion threshold is a non-cell-edge criterion threshold related to SUL. The first non-cell-edge criterion threshold is greater than the second non-cell-edge criterion threshold.

Exemplarily, the first non-cell-edge criterion threshold includes at least a first received power search threshold (s-SearchThresholdP), and the first non-cell-edge criterion threshold can further include a reception quality search threshold (s-SearchThresholdQ). The second non-cell-edge criterion threshold includes at least a second received power search threshold (s-SearchThresholdPSUL), and the second non-cell-edge criterion threshold can further include s-SearchThresholdQ. Among them, s-SearchThresholdP and s-SearchThresholdPSUL are used to compare with the RSRP of the serving cell, and s-SearchThresholdQ is used to compare with the RSRQ of the serving cell. The threshold of the first non-cell-edge criterion is greater than the threshold of the second non-cell-edge criterion means: the threshold used for comparison with RSRP in the first non-cell-edge criterion threshold is greater than the threshold used for comparison with RSRP in the threshold of the second non-cell-edge criterion , that is, s-SearchThresholdP>s-SearchThresholdPSUL.

Step 404: The terminal device determines whether to perform RRM measurement relaxation of neighboring cells based on the first non-cell-edge criterion threshold and the second non-cell-edge criterion threshold.

Based on its own support for SUL, the terminal device can evaluate whether it satisfies the non-cell-edge criterion by combining the above-mentioned first non-cell-edge criterion threshold and the second non-cell-edge criterion threshold, so as to determine whether it performs RRM measurement relaxation of neighboring cells.

For the case where the terminal device does not support SUL/only supports NUL:

In the case that the terminal device does not support the SUL, the terminal device determines to use the first non-cell-edge criterion threshold in the non-cell-edge criterion threshold sent by the network device. In response to the signal quality measurement result of the serving cell of the terminal device being greater than the first non-cell-edge criterion threshold, the terminal device performs RRM measurement relaxation of neighboring cells.

In the case that the terminal device does not support the SUL, the terminal device determines to use the first non-cell-edge criterion threshold in the non-cell-edge criterion threshold sent by the network device. In response to the signal quality measurement result of the serving cell of the terminal device being not greater than the first non-cell-edge criterion threshold, the terminal device does not perform RRM measurement relaxation of neighboring cells.

Exemplarily, when the RSRP measurement value Srxlev of the serving cell of the terminal device>s-SearchThresholdP, and the RSRQ measurement value Squal>s-SearchThresholdQ of the serving cell of the terminal device (in the case where the first non-cell edge criterion threshold includes s-SearchThresholdQ The terminal device will perform this judgment, otherwise, when only judging s-SearchThresholdP), the terminal device will perform the RRM measurement relaxation of the neighboring cell, otherwise, the terminal device will perform the RRM measurement of the neighboring cell according to the normal measurement method.

For terminal equipment supporting SUL:

In the case that the terminal device supports SUL, the terminal device will determine to use the second non-cell-edge criterion threshold in the non-cell-edge criterion threshold sent by the network device. In response to the signal quality measurement result of the serving cell of the terminal device being greater than the second non-cell-edge criterion threshold, the terminal device performs RRM measurement relaxation of neighboring cells.

In the case that the terminal device supports SUL, the terminal device will determine to use the second non-cell-edge criterion threshold in the non-cell-edge criterion threshold sent by the network device. In response to the signal quality measurement result of the serving cell of the terminal device being not greater than the second non-cell-edge criterion threshold, the terminal device does not perform RRM measurement relaxation of neighboring cells.

Exemplarily, when the RSRP measurement value Srxlev of the serving cell of the terminal device>s-SearchThresholdPSUL, and the RSRQ measurement value Squal>s-SearchThresholdQ of the serving cell of the terminal device (in the case where the second non-cell edge criterion threshold includes s-SearchThresholdQ The terminal device will perform this judgment, otherwise, when only judging s-SearchThresholdPSUL), the terminal device will perform the RRM measurement relaxation of the neighboring cell, otherwise, the terminal device will perform the RRM measurement of the neighboring cell according to the normal measurement method.

Optionally, the above-mentioned terminal equipment that supports or does not support SUL can also support or not support enhanced uplink coverage.

Exemplarily, Fig. 5 is a schematic diagram of cell coverage provided by an exemplary embodiment of the present application. As shown in FIG. 5 , for the same base station, the cell coverage 504 formed by DL and SUL is larger than the cell coverage 502 formed by DL and NUL. When a terminal device in this cell only supports NUL, within the range 501 determined according to the first received power search threshold (s-SearchThresholdP), the terminal device can perform RRM measurement relaxation of neighboring cells. Outside the range 501 determined according to the first received power search threshold (s-SearchThresholdP), the terminal device will perform RRM measurement of neighboring cells in a normal measurement manner. When a terminal device in the cell supports SUL, within the range 503 determined according to the second received power search threshold (s-SearchThresholdPSUL), the terminal device can perform RRM measurement relaxation of neighboring cells. Outside the range 503 determined according to the second received power search threshold (s-SearchThresholdPSUL), the terminal device will perform RRM measurement of neighboring cells in a normal measurement manner. Wherein, the range 503 determined according to s-SearchThresholdPSUL is larger than the range 501 determined according to s-SearchThresholdP, so a terminal device supporting SUL can perform RRM measurement relaxation of neighboring cells in a larger range than a terminal device not supporting SUL . Based on s-SearchThresholdP and s-SearchThresholdPSUL, it can be realized that for terminal equipment that supports or does not support SUL, the RRM measurement relaxation of neighboring cells can be performed within an appropriate range. At the same time, for terminal equipment that supports or does not support SUL, energy saving based on measurement relaxation can be achieved, and at the same time, the problem of untimely measurement of adjacent cells and the late discovery of adjacent cells can be avoided.

In summary, in the method provided in this embodiment, the network device sends the first non-cell-edge criterion threshold and the second non-cell-edge criterion threshold to the terminal device, and the first non-cell-edge criterion threshold and the second non-cell-edge criterion threshold can be Realize separately setting the non-cell edge criterion parameters used by the terminal equipment supporting or not supporting SUL. Targeted and accurate non-cell edge criterion parameters can be set, so that the terminal equipment that supports or does not support SUL can realize energy saving based on measurement relaxation and avoid neighbor The measurement of the cell is not timely, which leads to the problem that the adjacent cells are found too late.

Among them, s-SearchThresholdP and s-SearchThresholdPCE are used to compare with the RSRP of the serving cell, and s-SearchThresholdQ is used to compare with the RSRQ of the serving cell. The threshold of the third non-cell-edge criterion is greater than the threshold of the fourth non-cell-edge criterion means: the threshold used for comparing with RSRP in the threshold of the third non-cell-edge criterion is greater than the threshold used for comparing with RSRP in the threshold of the fourth non-cell-edge criterion , that is, s-SearchThresholdP>s-SearchThresholdPCE.

For the case where the terminal device does not support enhanced uplink coverage/only supports normal uplink coverage:

In the case that the terminal device does not support enhanced uplink coverage, the terminal device determines to use the third non-cell-edge criterion threshold in the non-cell-edge criterion threshold sent by the network device. In response to the signal quality measurement result of the serving cell of the terminal device being greater than the third non-cell-edge criterion threshold, the terminal device performs RRM measurement relaxation of neighboring cells.

In the case that the terminal device does not support enhanced uplink coverage, the terminal device determines to use the third non-cell-edge criterion threshold in the non-cell-edge criterion threshold sent by the network device. In response to the signal quality measurement result of the serving cell of the terminal device being not greater than the third non-cell-edge criterion threshold, the terminal device does not perform RRM measurement relaxation of neighboring cells.

Exemplarily, when the RSRP measurement value of the serving cell of the terminal device Srxlev>s-SearchThresholdP, and the RSRQ measurement value of the serving cell of the terminal device Squal>s-SearchThresholdQ (in the case where the third non-cell edge criterion threshold includes s-SearchThresholdQ The terminal device will perform this judgment, otherwise, when only judging s-SearchThresholdP), the terminal device will perform the RRM measurement relaxation of the neighboring cell, otherwise, the terminal device will perform the RRM measurement of the neighboring cell according to the normal measurement method.

For the case where the terminal device supports enhanced uplink coverage:

In response to the signal quality measurement result of the serving cell of the terminal device being not greater than the fourth non-cell-edge criterion threshold, the terminal device does not perform RRM measurement relaxation of neighboring cells.

Exemplarily, when the RSRP measurement value Srxlev of the serving cell of the terminal device>s-SearchThresholdPCE, and the RSRQ measurement value Squal>s-SearchThresholdQ of the serving cell of the terminal device (in the case where the fourth non-cell edge criterion threshold includes s-SearchThresholdQ The terminal device will perform this judgment, otherwise, when only judging s-SearchThresholdPCE), the terminal device will perform the RRM measurement relaxation of the neighboring cell, otherwise, the terminal device will perform the RRM measurement of the neighboring cell according to the normal measurement method.

Optionally, the above-mentioned terminal device that supports or does not support enhanced uplink coverage can also support or not support SUL.

As shown in FIG. 7 , for the same base station, the cell coverage 704 formed by DL and enhanced uplink coverage is larger than the cell coverage 702 formed by DL and normal uplink coverage. When a terminal device in this cell only supports normal uplink coverage, within the range 701 determined according to the first received power search threshold (s-SearchThresholdP), the terminal device can perform RRM measurement relaxation of neighboring cells. Outside the range 701 determined according to the first received power search threshold (s-SearchThresholdP), the terminal device will perform RRM measurement of neighboring cells in a normal measurement manner. When a terminal device in the cell supports enhanced uplink coverage, within the range 703 determined according to the third received power search threshold (s-SearchThresholdPCE), the terminal device can perform RRM measurement relaxation of neighboring cells. Outside the range 703 determined according to the third received power search threshold (s-SearchThresholdPCE), the terminal device performs RRM measurement of neighboring cells in a normal measurement manner. Wherein, the range 703 determined according to s-SearchThresholdPCE is larger than the range 701 determined according to s-SearchThresholdP, so a terminal device that supports enhanced uplink coverage can perform neighbor cell search in a larger range than a terminal device that does not support enhanced uplink coverage.

As shown in FIG. 9 , for the same base station, the cell coverage 908 formed by DL, SUL and enhanced uplink coverage is larger than the cell coverage 906 formed by DL, SUL and normal uplink coverage. The cell coverage 906 formed by DL, SUL and normal uplink coverage is larger than the cell coverage 904 formed by DL, NUL and enhanced uplink coverage. The cell coverage 904 formed by DL, NUL and enhanced uplink coverage is larger than the cell coverage 902 formed by DL, NUL and normal uplink coverage.
