[0034] It should be understood that all or part of the functions of the communication device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).

[0035] For ease of understanding, the communication process involved in the embodiments of the present application is introduced below.

[0036] Radio resource control (RRC) state and mobility management

[0037] Currently, the protocol defines three RRC states of terminal devices: RRC connected (RRC_connected) state, RRC idle (RRC-idle) state and RRC inactive (RRC-inactive) state.

[0038] The RRC connection state may refer to the state in which the terminal device is in when the RRC release is not performed after the random access process is completed. An RRC connection exists between the terminal device and a network device (e.g., an access network device). In the RRC connection state, the terminal device can transmit data with the network device, such as downlink data transmission and / or uplink data transmission. Alternatively, the terminal device can also transmit terminal device-specific data channels and / or control channels with the network device to transmit specific information or unicast information of the terminal device.

[0039] In the RRC connected state, the network device can determine the cell-level location information of the terminal device, that is, the network device can determine the cell to which the terminal device belongs. In the RRC connected state, after the terminal device moves, such as from one cell to another, the network device can control the terminal device to perform cell handover. Therefore, it can be seen that the mobility management of the terminal device in the RRC connected state may include cell handover. In addition, the mobility management of the terminal device in the RRC connected state can be controlled by the network device. Accordingly, the terminal device can switch to a designated cell according to the instructions issued by the network device.

[0040] The RRC idle state refers to the state of the terminal device when it is resident in a cell but is not performing random access. The terminal device usually enters the RRC idle state after being powered on or after RRC is released. In the RRC idle state, there is no RRC connection between the terminal device and the network device (such as the resident network device), the network device does not store the context of the terminal device, and no connection is established between the network device and the core network for the terminal device. If the terminal device needs to enter the RRC connected state from the RRC idle state, it is necessary to initiate the RRC connection establishment process.

[0041] In the RRC idle state, the core network (CN) can send a paging message to the terminal device, that is, the paging process can be triggered by the CN. Optionally, the paging area can also be configured by the CN. In some cases, for a terminal device in the RRC idle state, when the terminal device moves (for example, from one cell to another), the terminal device can initiate a cell reselection process. In other cases, for a terminal device in the RRC idle state, when the terminal device needs to access a cell, the terminal device can initiate a cell selection process. That is, the mobility management of the terminal device in the RRC idle state may include cell reselection and / or cell selection.

[0042] The RRC inactive state is defined to reduce air interface signaling, quickly restore wireless connections, and quickly resume data services. The RRC inactive state is a state between the connected and idle states. A terminal device previously entered the RRC connected state and then released the RRC connection with the network device, but the network device retained the terminal device's context. Furthermore, the connection established between the network device and the core network for the terminal device is not released. This means that the user plane and control plane bearers between the RAN and CN are still maintained, indicating a CN-NR connection.

[0043] In the RRC inactive state, the RAN can send a paging message to the terminal device, that is, the paging process can be triggered by the RAN. The RAN-based paging area is managed by the RAN, and the network equipment can know the location of the terminal device based on the RAN paging area level.

[0044] In some cases, for a terminal device in an RRC inactive state, when the terminal device moves (for example, from one cell to another), the terminal device may initiate a cell reselection process. In other cases, for a terminal device in an RRC inactive state, when the terminal device needs to access a cell, the terminal device may initiate a cell selection process. In other words, the mobility management of a terminal device in an RRC inactive state may include cell reselection and / or cell selection.

[0045] Whether cell selection, cell handover, or cell reselection, all can be performed based on the RRM measurement results. For example, when the RRM measurement result is greater than the RRM measurement threshold, the terminal device can perform cell selection, cell handover, or cell reselection. The following mainly introduces RRM measurement.

[0046] RRM measurements

[0047] RRM measurement is a type of mobility measurement. As mentioned above, whether it is cell selection, cell switching or cell reselection, it can be performed based on the RRM measurement results. Therefore, mobility measurement can be understood as the basis of mobility management. In other words, the purpose of RRM measurement is to achieve wireless resource management, where wireless resource management may include the mobility management mentioned above and / or the RRM measurement relaxation mechanism involved below. In some implementations, the terminal device may perform RRM measurements on the SSB and / or CSI-RS sent by the network device to obtain RRM measurement results.

[0048] RRM measurements include intra-frequency measurements and inter-frequency / inter-RAT measurements. Intra-frequency measurements involve measuring other frequencies within the same frequency band as the current serving cell and neighboring cell frequencies that share the same center frequency as the serving cell's supported frequency band. Inter-frequency / inter-RAT measurements involve measuring neighboring cell frequencies that differ from the serving cell's supported frequency band center frequency or that are not in the same system as the serving cell.

[0049] When the terminal device is in the RRC idle state or the RRC inactive state, there is no RRC connection between the terminal device and the network device. When the RRM measurement result of the cell where the terminal device resides (also called the service cell) is lower than a certain threshold (i.e., the RRM measurement threshold mentioned above), the terminal device can perform RRM measurements on the service cell and the cells adjacent to the service cell (also called neighboring cells) according to the same-frequency, different-frequency and / or different-system neighboring cell information configured by the network device in the system message, and determine whether the RRM measurement of the neighboring cell meets the cell reselection condition. If the RRM measurement result of the neighboring cell meets the cell reselection condition, the terminal device resides in the neighboring cell. When the terminal device is in the RRC connected state, there is an RRC connection between the terminal device and the network device, and the network device configures the terminal device to perform same-frequency, different-frequency and / or different-system neighboring cell measurements through RRC signaling. The terminal device reports the RRM measurements of the service cell and the neighboring cell to the network device through RRC signaling, so that the network device can switch the terminal device to a cell with better RRM measurement results based on the measurement results when the terminal device is in.

[0050] It should be noted that the above-mentioned RRM measurement results are used to indicate the communication quality of the terminal device. In some implementations, the above-mentioned RRM measurement results may include one or more of the following measurement quantities: signal amplitude (Srxlev), signal strength (Squal), reference signal received power (reference signal received power, RSRP), reference signal received quality (reference signal received quality, RSRQ), signal to noise ratio (SNR), signal to interference plus noise ratio (SINR), received signal strength indication (RSSI), etc.

[0051] In some implementations, the S criterion is defined as: Srxlev>0 and Squal>0 are satisfied simultaneously. Srxlev=Q rxlevmeas –(Q rxlevmin +Q rxlevminoffset )–P compensation -Qoffset temp ; Squal = Q qualmeas –(Q qualmin +Q qualminoffset )-Qoffset tempAmong them, Srxlev and Squal are the RSRP and RSRQ of the UE in the cell respectively; Qrxlevmeas and Qqualmeas are the RSRP and RSRQ measurement values ​​of the UE in the cell respectively; Qrxlevmin and Qqualmin are the minimum RSRP and minimum RSRQ required by the cell respectively, and this parameter is configured by the network through broadcast.

[0052] In addition, the above-mentioned RRM measurement threshold may include an intra-frequency measurement threshold (Sintrasearch) and an inter-frequency / inter-system measurement threshold (Snonintrasearch).

[0053] In some implementations, the intra-frequency measurement thresholds may include: an intra-frequency measurement signal amplitude threshold (SintrasearchP) and an intra-frequency measurement signal strength threshold (SintrasearchQ). SintrasearchP indicates the signal amplitude threshold for intra-frequency measurement, and SintrasearchQ indicates the signal strength threshold for intra-frequency measurement.

[0054] In other implementations, the inter-frequency / inter-system measurement thresholds may include: an inter-frequency / inter-system measurement signal amplitude threshold (SnonintrasearchP) and an inter-frequency / inter-system measurement signal strength threshold (SnonintrasearchQ). SnonintrasearchP indicates the signal amplitude threshold for inter-frequency / inter-system measurement. SnonintrasearchQ indicates the signal strength threshold for inter-frequency / inter-system measurement.

[0055] It should be noted that the “first RRM measurement threshold” and / or “second RRM measurement threshold” mentioned in the embodiments of the present application may be of the same type as the measurement threshold included in the above-mentioned first RRM measurement threshold.

[0056] After the terminal device obtains the RRM measurement result, the terminal device may further perform a first operation based on the RRM measurement result. The first operation may include one or more of the cell switching, cell reselection, cell selection described above, RRM measurement relaxation described below, supplementary uplink (SUL) carrier switching, and switching between a 2-step random access procedure and a 4-step random access procedure.

[0057] Some protocols require terminal devices to perform RRM measurements periodically, which results in high energy consumption. Frequent RRM measurements are unnecessary in certain measurement scenarios, such as when the terminal device is stationary or moving at a low speed. Therefore, to reduce terminal device energy consumption, RRM measurement power saving mechanisms and RRM measurement relax mechanisms have been introduced.

[0058] Power saving mechanism for RRM measurements

[0059] The following describes the RRM measurement rules followed by terminal devices in the RRC connected state when performing intra-frequency measurements and inter-frequency / inter-system measurements.

[0060] In the same-frequency measurement scenario, if the RRM measurement result of the serving cell satisfies: Srxlev>SIntraSearchP and Squal>SIntraSearchQ, the terminal device may choose not to perform the same-frequency measurement; otherwise, the terminal device needs to perform the same-frequency measurement.

[0061] In the scenario of inter-frequency / inter-system measurement, if the RRM measurement result of the serving cell satisfies: Srxlev>SnonIntraSearchP and Squal>SnonIntraSearchQ, the terminal device can choose not to perform inter-frequency / inter-system measurement, otherwise, the terminal device needs to perform inter-frequency / inter-system measurement.

[0062] The above describes the RRM measurement rules followed by terminal devices in the RRC connected state. The following describes the RRM measurement rules followed by terminal devices in the RRC idle state or the RRC non-connected state.

[0063] A terminal device in an RRC connected state can perform RRM measurement based on the S-measurement criterion, wherein, if the RRM measurement result obtained by the terminal device performing the RRM measurement is greater than the RRM measurement threshold, the terminal device only needs to perform RRM measurement of the serving cell and does not perform RRM measurement outside the serving cell; otherwise, if the RRM measurement result obtained by the terminal device performing the RRM measurement is less than or equal to the RRM measurement threshold, the terminal device performs RRM measurement according to the configuration of the measurement object (MO).

[0064] In some implementations, in the S-measure criterion, the terminal device can perform RRM measurements based on the synchronization / physical broadcast channel block (SSB) and / or the channel state information reference signal (CSI-RS).

[0065] RRM measurement relaxation mechanism

[0066] RRM measurement relaxation may also be referred to as neighboring cell measurement relaxation, or neighboring cell RRM measurement relaxation. There are various ways to implement RRM measurement relaxation. For example, the terminal device may implement RRM measurement relaxation by increasing the RRM measurement period (i.e., reducing the number of RRM measurements). For another example, the terminal device may implement RRM measurement relaxation by reducing the number of measured neighboring cells. For another example, the terminal device may implement RRM measurement relaxation by reducing the number of measured frequencies.

[0067] For the relaxation of RRM measurements of terminal devices in RRC idle state and RRC inactive state, the protocol defines two criteria, namely the non-cell edge (not-cell-edge) criterion and the low-mobility (low-mobility) criterion. The terminal device can determine whether it meets the not-cell-edge criterion and / or the low-mobility criterion based on the RRM measurement results. If the terminal device meets the not-cell-edge criterion and / or the low-mobility criterion, the terminal device can relax the RRM measurement.

[0068] The not-cell-edge criterion is used to determine whether a terminal device is located at the edge of a serving cell. If the terminal device is located at a non-edge cell of a serving cell, cell reselection is not necessary, and RRM measurements can be relaxed to achieve energy conservation. If the terminal device is located at the edge of a serving cell, cell reselection is more necessary, and RRM measurements can be omitted.

[0069] The not-cell-edge criterion primarily defines the RRM measurement threshold. By comparing the RRM measurement result with the RRM measurement threshold, it can be determined whether the terminal device is located in a non-edge cell location. For example, if the RRM measurement result is greater than the RRM measurement threshold, it indicates that the terminal device is located in a non-edge cell location of the serving cell; if the RRM measurement result is less than or equal to the RRM measurement threshold, it indicates that the terminal device is located in an edge cell location of the serving cell.

[0070] The following takes the RRM measurement results of RSRP and RSRQ as an example to introduce the not-cell-edge criterion. The network device can define the two threshold values ​​s-SearchThresholdP and s-SearchThresholdQ of the not-cell-edge criterion by configuring the cell edge evaluation (cellEdgeEvaluation) parameter to the terminal device. Among them, s-SearchThresholdP is the measurement threshold value of RSRP, and s-SearchThresholdQ is the measurement threshold value of RSRQ. The terminal device can measure the RSRP and RSRQ of the serving cell to obtain the measurement value of RSRP and the measurement value of RSRQ of the serving cell. When the measurement value of RSRP of the serving cell is greater than s-SearchThresholdP, and the measurement value of RSRQ is greater than s-SearchThresholdQ, the terminal device meets the not-cell-edge criterion, and the terminal device can relax the RRM measurement.

[0071] It should be noted that, in some implementations, the s-SearchThresholdP configured on the network device is usually smaller than SIntraSearchP and SnonIntraSearchP. In other implementations, the s-SearchThresholdQ configured on the network device may be smaller than SIntraSearchQ and SnonIntraSearchQ.

[0072] Of course, the network device may also configure only one parameter of s-SearchThresholdP and s-SearchThresholdQ. For example, the network device may configure only s-SearchThresholdP, but not s-SearchThresholdQ. In this case, the terminal device may only measure the RSRP of the serving cell. When the measured value of the RSRP of the serving cell is greater than s-SearchThresholdP, the terminal device satisfies the not-cell-edge criterion, and the terminal device may relax the RRM measurement. For another example, the network device may only configure s-SearchThresholdQ, but not s-SearchThresholdP. In this case, the terminal device may only measure the RSRQ of the serving cell. When the measured value of the RSRQ of the serving cell is greater than s-SearchThresholdQ, the terminal device satisfies the not-cell-edge criterion, and the terminal device may relax the RRM measurement.

[0073] The low-mobility criterion is mainly used to determine whether the terminal device is in a low-mobility state. If the terminal device is in a low-mobility state, that is, the location of the terminal device is relatively fixed, then the terminal device has little need for cell reselection, and the terminal device can perform relaxed RRM measurements. If the terminal device is in a high-mobility state, that is, the location of the terminal device changes greatly, then the terminal device has a greater need for cell reselection, and the terminal device may not perform relaxed RRM measurements.

[0074] Whether the terminal device is in a low-mobility state can be judged based on the RRM measurement results of the serving cell. For example, the terminal device can measure the RRM measurement results of the serving cell at different times. If the RRM measurement results of the serving cell change little at different times, that is, the signal quality of the serving cell is relatively stable, it indicates that the terminal device is in a low-mobility state.

[0075] Taking the RRM measurement result as RSRP as an example, the terminal device can measure the RSRP of the serving cell. If the RSRP of the serving cell changes little, it indicates that the terminal device is in a low-mobility state, and the terminal device can perform relaxed RRM measurements.

[0076] For the low-mobility criterion, the terminal device can determine whether it meets the low-mobility criterion by judging whether it meets the low-mobility criterion parameters. Currently, two low-mobility criterion parameters are defined in the protocol: the evaluation duration t-SearchDeltaP and the RRM measurement threshold s-SearchDeltaP. If the RRM measurement result of the serving cell is less than the RRM measurement threshold s-SearchDeltaP within the time t-SearchDeltaP, it indicates that the terminal device meets the low-mobility criterion, and the terminal device can perform relaxed RRM measurements.

[0077] In one implementation, when the terminal device meets the low-mobility criterion, the terminal device uses a longer measurement interval when performing RRM measurements on neighboring cells. For example, a fixed scaling factor K can be used to increase the measurement interval.

[0078] In another implementation, the above low-mobility criterion can be expressed as (SrxlevRef – Srxlev) < s-SearchDeltaP is satisfied within the time t-SearchDeltaP, where SrxlevRef represents the signal amplitude reference value of the serving cell. Generally, the use of SrxlevRef can follow the following rules.

[0079] Rule 1: When the terminal device performs cell selection or cell reselection and the serving cell changes, the terminal device needs to set the signal reference value to the current measured value of the signal amplitude of the serving cell (ie, Srxlev).

[0080] Rule 2: If the signal amplitude of the serving cell is greater than the signal amplitude reference value, that is, (Srxlev-SrxlevRef)>0, the terminal device needs to set the signal reference value to the current measured value of the signal amplitude of the serving cell.

[0081] Rule 3: If the measurement relaxation criteria are not met within the t-SearchDelta time (if the measurement relaxation requirements are not met, the reference value is updated to the current measurement value), the terminal device needs to set the signal reference value to the current measurement value of the signal amplitude of the serving cell.

[0082] If the terminal device is configured with both the not-cell-edge criterion and the low-mobility criterion, the network device may also notify the terminal device of the triggering conditions for RRM measurement relaxation, and the terminal device may perform RRM measurement relaxation when the triggering conditions are met. The triggering condition may be satisfying the not-cell-edge criterion and / or the low-mobility criterion. For example, the network device may indicate the relationship between the not-cell-edge criterion and the low-mobility criterion to the terminal device, such as the network device may indicate whether the two are in an "and" relationship or an "or" relationship. If the two are in an "and" relationship, it means that the terminal device needs to satisfy both the not-cell-edge criterion and the low-mobility criterion at the same time before it can perform RRM measurement relaxation. If the two are in an "or" relationship, it means that the terminal device can perform RRM measurement relaxation as long as it satisfies any one of the criteria (such as the not-cell-edge criterion or the low-mobility criterion).

[0083] Building on the low mobility and not cell edge criteria, Release 17 further explores RRM measurement relaxations for stationary devices, introducing the R17 stationary and R17 not cell edge criteria. The R17 stationary criterion reuses the R16 low mobility criterion, while the R17 not cell edge criterion reuses the R16 not cell edge criterion. In some implementations, network devices can configure different RRM measurement thresholds for the R16 and R17 criteria.

[0084] Low capacity (RedCap) terminals

[0085] Currently, RedCap terminals are introduced in communication protocols (e.g., NR R17). For ease of understanding, the following describes three applicable scenarios for RedCap terminals in conjunction with scenarios 1 to 3. Of course, in the embodiments of the present application, the above-mentioned RedCap terminals can also be terminal devices for other scenarios, and the embodiments of the present application do not limit this.

[0086] In Scenario 1, the RedCap terminals can be industrial wireless sensors. Industrial wireless sensors typically have relatively low requirements for transmission latency and reliability. For example, compared to the transmission latency and reliability requirements of URLLC services, the transmission latency and reliability requirements of industrial wireless sensor services are lower. Furthermore, the cost and power consumption of industrial wireless sensors are lower than those of URLLC devices and / or eMBB devices.

[0087] In Scenario 2, the RedCap terminal can be a video surveillance device. It can be used in smart cities, industrial factories, and other environments. For example, video surveillance equipment used in smart cities can collect and process smart city-related data to more effectively monitor and control urban resources within the smart city, providing more effective services to residents.

[0088] In scenario 3, the RedCap terminal may be a wearable device, such as a smart watch, a smart ring, an electronic health device, a medical monitoring device, etc. Generally, such devices are relatively small in size.

[0089] Some protocols (e.g., R17) limit the bandwidth supported by RedCap terminals. For example, for FR1, the maximum bandwidth supported by RedCap terminals is 20 MHz. For another example, for FR2, the maximum bandwidth supported by RedCap terminals is 100 MHz. This maximum bandwidth can include both the radio frequency (RF) bandwidth and the baseband (BB) bandwidth.

[0090] In some protocols (for example, the communication protocol of R18), further low-complexity and low-cost designs are introduced for RedCap terminals supporting the FR1 frequency band (also known as "enhanced RedCap, eRedCap) enhanced low-capability terminals"). For example, consider reducing the baseband bandwidth of the RedCap terminal to 5MHz. Among them, the 5MHz baseband bandwidth can be only for the physical downlink shared channel (PDSCH) and the physical uplink shared channel (PUSCH) channels. For the RF bandwidth of the RedCap terminal and the baseband bandwidth of other physical layer channels / signals except PDSCH and PUSCH, 20MHz can be maintained unchanged.

[0091] Based on current RAN1 evaluation results, when the bandwidth of PDSCH (such as paging PDSCH, system information block (SIB) 1 PDSCH, other system information (OSI) PDSCH, message 2 (Mg2) PDSCH, and message 4 (Mg4) PDSCH) transmitted by a network device exceeds 5MHz, for terminal devices that support a lower maximum bandwidth (for example, eRedCap terminals that only support 5MHz baseband bandwidth), the terminal device may only be able to receive data with a partial bandwidth. In this case, compared with ordinary terminal devices (also known as "legacy terminals"), under the same signal to interference plus noise ratio (SINR) conditions, the data received by the terminal device with a lower maximum bandwidth may have a higher block error rate (BLER). In other words, under the same BLER, a terminal device supporting a lower maximum bandwidth requires a higher SINR than a terminal device supporting a higher maximum bandwidth (for example, a terminal device with a baseband bandwidth capability of 20 MHz). Therefore, there will be a certain downlink coverage loss for terminal devices supporting a lower maximum bandwidth.

[0092] Based on the previous introduction to RRM measurement, it can be seen that for terminal devices that support a lower maximum bandwidth and terminal devices that support a larger maximum bandwidth, the parameters associated with RRM measurement (for example, the RRM measurement threshold) are the same. This parameter setting method does not take into account the differences in downlink coverage of terminal devices, resulting in an unreasonable setting method for the parameters associated with RRM measurement.

[0093] Taking RRM measurement as an example, including whether to enable neighbor cell measurement, for eRedCap terminals and ordinary terminals, if both correspond to the same RRM measurement threshold, the RRM measurement threshold setting may be relatively large. In other words, when the eRedCap terminal determines to enable neighbor cell measurement based on RRM measurement, the communication quality between the eRedCap terminal and the network device may be very poor or even impossible.

[0094] Therefore, an embodiment of the present application provides a method for wireless communication. By associating a first parameter for RRM measurement with a terminal type, that is, determining the parameter for RRM measurement based on the terminal type, this helps improve the rationality of configuring the first parameter. For ease of understanding, the method for wireless communication according to an embodiment of the present application is described below in conjunction with Figure 2.

[0095] FIG2 is a schematic flow chart of a method for wireless communication according to an embodiment of the present application. The method shown in FIG2 includes step S210.

[0096] In step S210 , the first terminal device determines a first parameter for RRM measurement.

[0097] In some implementations, the first parameter may be associated with a terminal type of the first terminal device, or in other words, the first parameter corresponds to the terminal device type of the first terminal device.

[0098] In some implementations, the terminal type is used to indicate the maximum bandwidth supported by the associated terminal device, or in other words, the terminal type is determined based on the maximum bandwidth supported by the terminal device.

[0099] In some implementations, the maximum bandwidth supported by the terminal device may include the maximum baseband bandwidth supported by the terminal device. In other implementations, the maximum bandwidth supported by the terminal device may include the maximum radio frequency bandwidth supported by the terminal device. Of course, in the embodiments of the present application, the maximum bandwidth supported by the terminal device may include both the maximum radio frequency bandwidth and the maximum baseband bandwidth supported by the terminal device.

[0100] In some implementations, the maximum bandwidth supported by the terminal device may be the maximum bandwidth for a certain channel. For example, taking the maximum bandwidth as the maximum baseband bandwidth, the maximum baseband bandwidth supported by the terminal device may be for PDSCH and / or PUSCH. Of course, in the embodiment of the present application, the maximum bandwidth supported by the terminal device may be the maximum bandwidth for all channels, and the embodiment of the present application is not limited to this.

[0101] In some implementations, the terminal type may include one or more of an eRedCap terminal, a RedCap terminal, and an ordinary terminal (also known as a "legacy terminal"), which is not limited in the embodiments of the present application.

[0102] In the embodiment of the present application, different terminal types within the plurality of terminal types may be associated with different parameters for RRM measurement, or in other words, one parameter for RRM measurement may be associated with one of the plurality of terminal types. Of course, in the embodiment of the present application, some different terminal types within the plurality of terminal types may correspond to different parameters for RRM measurement, or in other words, one parameter for RRM measurement may be associated with multiple different terminal types. The embodiment of the present application does not specifically limit the above-mentioned association relationship.

[0103] In some implementations, a first parameter may be associated with the terminal type of the first terminal device. A second parameter for RRM measurement (e.g., a second RRM measurement threshold hereinafter) may be associated with the terminal type of the second terminal device, where the maximum baseband bandwidth supported by the first terminal device is less than the maximum baseband bandwidth supported by the second terminal device.

[0104] For example, the terminal type of the first terminal device may be an eRedCap terminal, that is, the maximum baseband bandwidth supported by the first terminal device for transmitting PDSCH and / or PUSCH is 5 MHz. Accordingly, the terminal type of the second terminal device may be an ordinary terminal. Of course, in an embodiment of the present application, the terminal type of the first terminal device may be a RedCap terminal, and accordingly, the terminal type of the second terminal device may be an ordinary terminal. Alternatively, the terminal type of the first terminal device may be an eRedCap terminal, and accordingly, the terminal type of the second terminal device may be a RedCap terminal.

[0105] It should be noted that, in the embodiment of the present application, the second parameter associated with the terminal type of the second terminal device may continue to use the value of the parameter in the traditional RRM measurement. For example, when the second terminal device is an ordinary terminal device, the second parameter associated with the terminal type of the second terminal device may continue to use the value of the parameter in the traditional RRM measurement. Of course, in the embodiment of the present application, the second parameter associated with the terminal type of the second terminal device may be obtained after adjustment based on the value of the parameter in the traditional RRM measurement. The adjustment may, for example, include increasing or decreasing the parameter in the traditional RRM measurement. For example, when the second terminal device is a RedCap terminal, the second parameter associated with the terminal type of the second terminal device may be obtained after adjustment based on the value of the parameter in the traditional RRM measurement.

[0106] The above describes the terminal type in the embodiment of the present application, and the following describes the first parameter in the embodiment of the present application. In some implementations, the first parameter may include a first RRM measurement threshold or a first adjustment parameter.

[0107] Taking the example that the first parameter includes the first RRM measurement threshold, the embodiment of the present application does not limit the type of the above-mentioned first RRM measurement threshold. The above-mentioned first RRM measurement threshold includes one or more of the RSRP threshold, RSRQ threshold, and SINR threshold.

[0108] In addition, the embodiment of the present application does not limit the function of the first RRM measurement threshold. In some implementations, the function of the first RRM measurement threshold may be similar to the function of the RRM measurement threshold in the known RRM measurement process. For example, the first RRM measurement threshold includes one or more of the following: an RRM measurement threshold in the S criterion associated with RRM measurement; an RRM measurement threshold associated with the start of neighboring cell measurement; an RRM measurement threshold associated with the relaxation criterion of neighboring cell RRM measurement; and an RRM measurement threshold associated with the cell measurement result obtained by merging L1 SSB measurement results. Of course, in the embodiment of the present application, the function of the first RRM measurement threshold may also be the function of other RRM measurement thresholds introduced in future communication systems.

[0109] Taking the example that the first RRM measurement threshold includes the RRM measurement threshold in the S criterion associated with the RRM measurement, the first RRM measurement threshold may include Q rxlevmin_type1 and / or Q qualmin_type1 , where Q rxlevmin_type1 Indicates the minimum RSRP required by the terminal type cell for the first terminal device, Q qualmin_type1 Indicates the minimum RSRQ required by the terminal type cell for the first terminal device.

[0110] Taking the first RRM measurement threshold including the RRM measurement threshold associated with the neighboring cell measurement start as an example, in some implementations, the first RRM measurement threshold may include an RRM threshold for starting the same-frequency measurement for the terminal type of the first terminal device, for example, the same-frequency measurement signal amplitude threshold (SintrasearchP _type1 ) and the same-frequency measurement signal strength threshold (SintrasearchQ _type1 ). Among them, SintrasearchP _type1 Used to indicate the signal amplitude threshold for starting the same-frequency measurement for the terminal type of the first terminal device. _type1 Used to indicate the signal strength threshold for starting same-frequency measurement for the terminal type of the first terminal device.

[0111] In some other implementations, the first RRM measurement threshold may include an RRM measurement threshold for starting inter-frequency / inter-system measurement for the terminal type of the first terminal device. For example, an inter-frequency / inter-system measurement signal amplitude threshold (SnonintrasearchP _type1 ) and the signal strength threshold for heterogeneous frequency / system measurement (SnonintrasearchQ _type1 ). Among them, SnonintrasearchP _type1 Used to indicate the signal amplitude threshold for starting inter-frequency / inter-system measurement for the terminal type of the first terminal device. _type1 Used to indicate the signal strength threshold for starting hetero-frequency / hetero-system measurement for the terminal type of the first terminal device.

[0112] Taking the first RRM measurement threshold including the RRM measurement threshold associated with the neighboring cell RRM measurement relaxation criterion as an example, in some scenarios, if the RRM measurement relaxation criterion includes the not-cell-edge criterion, the first RRM measurement threshold may include s-SearchThresholdP _type1 and s-SearchThresholdQ _type1 , where s-SearchThresholdP _type1 is the measurement threshold value of RSRP of the terminal type for the first terminal device, s-SearchThresholdQ _type1 is the measurement threshold value of the RSRQ of the terminal type for the first terminal device.

[0113] In some scenarios, if the RRM measurement relaxation criteria include a low-mobility criterion, the first RRM measurement threshold may include s-SearchDeltaP _type1 Threshold, s-SearchDeltaP _type1 The threshold is a threshold for the terminal type of the first terminal device.

[0114] In some scenarios, if the RRM measurement relaxation criterion includes the stationary criterion, the first RRM measurement threshold may include s-SearchDeltaP -Stationary_type1 Threshold, s-SearchDeltaP -Stationary_type1 The threshold is a threshold for the terminal type of the first terminal device.

[0115] It should be noted that, for other RRM measurement relaxation criteria, the meaning of the first RRM measurement threshold is similar to that described above and will not be repeated here for the sake of brevity.

[0116] Taking the first RRM measurement threshold including the RRM measurement threshold associated with the cell measurement result obtained by combining the L1 SSB measurement result as an example, the first RRM measurement threshold may include "absThreshSS-BlocksConsolidation _type1 ", represents the RRM measurement threshold associated with the cell measurement result obtained by combining the L1 SSB measurement results for the terminal type of the first terminal device.

[0117] It should be noted that in the embodiment of the present application, the RRM measurement threshold associated with the cell measurement result obtained based on the L1 SSB measurement result merging can be understood as a threshold for merging the layer 1 measurement results for each RS index. In some scenarios, it can be used as the minimum threshold for evaluating whether each beam in the ranked cell is a good beam during cell reselection. In other scenarios, it can also be the minimum threshold for beam selection.

[0118] The first adjustment parameter may be used to adjust the second RRM measurement threshold to obtain the first RRM measurement threshold, wherein the second RRM measurement threshold may be associated with the terminal type of the second terminal device introduced above.

[0119] In the embodiment of the present application, the second RRM measurement threshold is not limited. The type and / or function of the second RRM measurement threshold can refer to the introduction of the first RRM measurement threshold above.

[0120] In addition, the embodiments of the present application do not limit the relationship between the first RRM measurement threshold and the second RRM measurement threshold. In some implementations, the type of the first RRM measurement threshold may be the same as the type of the second RRM measurement threshold. In other implementations, the function of the first RRM measurement threshold may be the same as the function of the second RRM measurement threshold. In other implementations, the function and type of the first RRM measurement threshold may be the same as the function and type of the second RRM measurement threshold. Of course, in the embodiments of the present application, the first RRM measurement threshold may be different from the second RRM measurement threshold.

[0121] It should be noted that, in some scenarios, the network device also needs to determine the first parameter, wherein the meaning of the first parameter can be found in the above introduction, and for the sake of brevity, it will not be repeated here.

[0122] The above describes the meaning of the first parameter in the embodiment of the present application. The following describes the method for obtaining the first RRM measurement threshold based on the first parameter in the embodiment of the present application in combination with acquisition method 1 and acquisition method 2.

[0123] Acquisition method 1: obtaining a first RRM measurement threshold based on the first adjustment parameter adjustment.

[0124] That is, the above method further includes: the first terminal device adjusts the second RRM measurement threshold based on the first adjustment parameter to obtain the first RRM measurement threshold associated with the terminal type of the first terminal device.

[0125] It should be noted that, in the embodiment of the present application, the above adjustment may include an increase. For example, the first terminal device may increase the second RRM measurement threshold based on the first adjustment parameter to obtain the first RRM measurement threshold. Of course, in the embodiment of the present application, the above adjustment may also include a decrease, which is not limited in the embodiment of the present application.

[0126] In some implementations, the first adjustment parameter includes a first offset value. Accordingly, the first RRM measurement threshold is obtained by adjusting the first offset value based on the second RRM measurement threshold. For example, the first RRM measurement threshold may be obtained by increasing the first offset value based on the second RRM measurement threshold. For another example, the first RRM measurement threshold may be obtained by decreasing the first offset value based on the second RRM measurement threshold.

[0127] It should be noted that in the embodiment of the present application, the first offset value may be a positive number, or a negative number. Alternatively, the first offset value may be an integer, or a fraction, which is not limited in the embodiment of the present application.

[0128] Furthermore, in the embodiments of the present application, there is no limitation on the manner in which the first adjustment parameter is obtained. In some implementations, the first adjustment parameter may be preconfigured or predefined. For example, the first adjustment parameter may be predefined by a communication protocol. Of course, in the embodiments of the present application, the first adjustment parameter may be configured by a network device, for example, by broadcasting configuration information.

[0129] For example, assuming that the second RRM measurement threshold includes Q rxlevmin , the first offset value is denoted as Q rxlevminoffset_type1 , then Srxlev=Q rxlevmeas –(Q rxlevmin +Q rxlevminoffset +Q rxlevminoffset_type1 )–P compensation -Qoffset temp .

[0130] For another example, assuming that the second RRM measurement threshold includes Q qualmin , the first offset value is denoted as Q qualminoffset_type1 , then Squal=Q qualmeas –(Q qualmin +Q qualminoffset +Q qualminoffset_type1)-Qoffset temp .

[0131] For another example, assuming that the second RRM measurement threshold includes Q rxlevmin , the first offset value is denoted as Q rxlevminoffset_type1 , then Srxlev=Q rxlevmeas –(Q rxlevmin +Q rxlevminoffset )–P compensation -Qoffset temp -Q rxlevoffset_type1 .

[0132] For another example, assuming that the second RRM measurement threshold includes Q qualmin , the first offset value is denoted as Q qualminoffset_type1 , then Squal=Q qualmeas –(Q qualmin +Q qualminoffset )-Qoffset temp -Q qualoffset_type1 .

[0133] It should be noted that the adjustment method for other RRM measurement thresholds is the same as that for Q rxlevmin and Q qualmin The adjustment method is similar, which will be introduced in Example 1 and Example 2 below. For the sake of brevity, it will not be repeated here.

[0134] Acquisition method 2: directly configure the first RRM measurement threshold.

[0135] That is to say, a separate RRM measurement threshold may be directly configured for the terminal device type of the first terminal device.

[0136] In addition, in the embodiments of the present application, there is no limitation on the method for obtaining the first RRM measurement threshold. In some implementations, the first RRM measurement threshold may be preconfigured or predefined. For example, the first RRM measurement threshold may be predefined by a communication protocol. Of course, in the embodiments of the present application, the first RRM measurement threshold may be configured by a network device. For example, the network device may configure the first RRM measurement threshold by broadcasting configuration information.

[0137] For example, a separate RRM measurement threshold is introduced for the terminal type of the first terminal device: Q rxlevmin_type1 and Q qualmin_type1 . Accordingly, Srxlev = Q rxlevmeas –(Q rxlevmin_type1 +Q rxlevminoffset )–P compensation -Qoffset temp , Squal=Q qualmeas –(Qqualmin_type1 +Q qualminoffset )-Qoffset temp .

[0138] It should be noted that for other types of RRM measurement thresholds, the method of setting a separate RRM threshold is the same as the Q rxlevmin_type1 and Q qualmin_type1 The setting method is similar, which will be introduced below in combination with Example 1 and Example 2. For the sake of brevity, it will not be repeated here.

[0139] For ease of understanding, the following describes the solution of the embodiment of the present application in conjunction with Figures 3 and 4. It should be noted that the solution of the embodiment of the present application is not limited to the following two embodiments.

[0140] In Example 1, it is assumed that for a terminal device 1 in an RRC IDLE / INACTIVE state, in the neighboring area measurement start criterion and the neighboring area measurement relaxation criterion, a separate RSRP measurement threshold (also called a first RSRP measurement threshold) and an RSRQ measurement threshold (also called a first RSRQ measurement threshold) are introduced for the terminal type corresponding to the terminal device 1. The terminal device 1 can be used as an example of the first terminal device introduced above.

[0141] For ease of understanding, the following describes a method for wireless communication according to an embodiment of the present application in conjunction with Figure 3. The method shown in Figure 3 includes steps S310 to S340.

[0142] In step S310 , the network device sends configuration information 2 related to RRC IDLE / INACTIVE state RRM measurement to the terminal device 2 .

[0143] In some implementations, the configuration information 2 may include one or more of the following: RRM measurement threshold 2 for evaluating whether to start neighbor cell measurement: a second RSRP threshold 1, and a second RSRQ threshold 2; RRM measurement threshold 2 for evaluating whether to perform relaxed measurement for the neighbor cell: a second RSRP threshold 3 and a second RSRQ threshold 4.

[0144] In some implementations, the terminal device 2 may be understood as an ordinary terminal device. Accordingly, the value of the RRM measurement threshold 2 may be understood as the value of the RRM measurement threshold in a known protocol.

[0145] It should be noted that the above RRM measurement threshold 2 can be understood as an RRM measurement threshold corresponding to one or more RRM measurement criteria of the not at cell edge criterion, the low mobility criterion, and the stationary criterion.

[0146] In step S320 , the terminal device 1 determines an RRM measurement threshold 1 for the RRC IDLE / INACTIVE state.

[0147] In some implementations, the RRM measurement threshold 1 is associated with the terminal type of the terminal device 1. The RRM measurement threshold 1 includes: an RRM measurement threshold 1 for evaluating whether to initiate neighbor cell measurement: a first RSRP threshold 1, and a first RSRQ threshold 2; and an RRM measurement threshold 1 for evaluating whether to perform relaxed measurement for a neighbor cell: a first RSRP threshold 3, and a first RSRQ threshold 4.

[0148] It should be noted that the above RRM measurement threshold 1 can be understood as an RRM measurement threshold corresponding to one or more RRM measurement criteria of the not at cell edge criterion, the low mobility criterion, and the stationary criterion.

[0149] In some implementations, the above step S320 may include step S321 and / or step S322.

[0150] In step S321 , the network device sends configuration information 1 to terminal device 1 , where the configuration information 1 is used to configure RRM measurement threshold 1 .

[0151] It should be noted that the configuration information 1 and the configuration information 2 may be the same configuration information, and accordingly, the network device may send the configuration information in a broadcast manner. Of course, the configuration information may also be different configuration information, and this embodiment of the application does not limit this.

[0152] In step S322 , terminal device 1 determines offset value 1 (denoted by “offset1”), and adjusts RRM measurement threshold 2 based on offset value 1 to obtain RRM measurement threshold 1 .

[0153] For example, RRM measurement threshold 1=RRM measurement threshold 2+offset 1, where offset 1 may be determined by network configuration or in a protocol predefined manner.

[0154] In step S330, terminal device 1 performs RRM measurement based on RRM measurement threshold 1 and obtains RRM measurement result 1. Correspondingly, terminal device 2 performs RRM measurement based on RRM measurement threshold 2 and obtains RRM measurement result 2.

[0155] In step S340 , terminal device 1 performs RRM measurement-related evaluation based on RRM measurement result 1 . Correspondingly, terminal device 2 performs RRM measurement-related evaluation based on RRM measurement result 2 .

[0156] In some implementations, the RRM measurement-related evaluation may include one or more of the following: evaluating whether to start neighbor cell measurement; and evaluating whether to perform relaxed RRM measurement on neighbor cells.

[0157] The relaxed RRM measurement performed on the neighboring cell may include one or more evaluations of a not at cell edge criterion, a low mobility criterion, and a stationary criterion.

[0158] In embodiment 2, for the terminal type of terminal device 1 in RRC IDLE / INACTIVE state, a separate absThreshSS-BlocksConsolidation threshold (hereinafter referred to as the "first absThreshSS-BlocksConsolidation threshold") is introduced. Terminal device 1 can be used as an example of the first terminal device introduced above.

[0159] For ease of understanding, the following describes a method for wireless communication according to another embodiment of the present application in conjunction with Figure 4. The method shown in Figure 4 includes steps S410 to S440.

[0160] In step S410 , the network device sends configuration information 2 related to RRC IDLE / INACTIVE state RRM measurement to the terminal device 2 .

[0161] In some implementations, the configuration information 2 may include a second absThreshSS-BlocksConsolidation threshold.

[0162] In some implementations, the terminal device 2 may be understood as an ordinary terminal device. Accordingly, the value of the second absThreshSS-BlocksConsolidation threshold may be understood as being determined according to the value of the absThreshSS-BlocksConsolidation threshold in a known protocol.

[0163] In step S420, the terminal device 1 determines a first absThreshSS-BlocksConsolidation threshold for use in RRC IDLE / INACTIVE state RRM measurement.

[0164] In some implementations, the first absThreshSS-BlocksConsolidation threshold is associated with the terminal type of the terminal device 1 .

[0165] In some implementations, the above step S420 may include step S421 and / or step S422.

[0166] In step S421 , the network device sends configuration information 1 to terminal device 1 , where the configuration information 1 is used to configure a first absThreshSS-BlocksConsolidation threshold.

[0167] It should be noted that the configuration information 2 and the configuration information 1 can be the same configuration information, and accordingly, the network device can send the configuration information in a broadcast manner. Of course, the configuration information can also be different information, and this embodiment of the application does not limit this.

[0168] In step S422 , the terminal device 1 determines a first absThreshSS-BlocksConsolidation threshold.

[0169] In some implementations, terminal device 1 determines an offset value 2 (denoted by "offset2") and adjusts the second absThreshSS-BlocksConsolidation threshold based on offset value 2 to obtain the first absThreshSS-BlocksConsolidation threshold. For example, the first absThreshSS-BlocksConsolidation threshold = the second absThreshSS-BlocksConsolidation threshold + offset2, where the value of offset2 can be configured by the network or predefined by the protocol.

[0170] It should be noted that when the absThreshSS-BlocksConsolidation threshold (e.g., the first absThreshSS-BlocksConsolidation threshold and / or the second absThreshSS-BlocksConsolidation threshold) is a different type of threshold, the above offset values ​​may be the same or different. The absThreshSS-BlocksConsolidation threshold (e.g., the first absThreshSS-BlocksConsolidation threshold and / or the second absThreshSS-BlocksConsolidation threshold) may include one or more of an RSRP threshold, an RSRQ threshold, and an SINR threshold.

[0171] In step S430, terminal device 1 performs RRM measurement based on the first absThreshSS-BlocksConsolidation threshold to obtain RRM measurement result 1. Correspondingly, terminal device 2 performs RRM measurement based on the second absThreshSS-BlocksConsolidation threshold to obtain RRM measurement result 2.

[0172] In step S440 , terminal device 1 performs RRM measurement-related evaluation based on RRM measurement result 1 . Correspondingly, terminal device 2 performs RRM measurement-related evaluation based on RRM measurement result 2 .

[0173] It should be noted that in the embodiments of the present application, the role of the first adjustment parameter is not limited. For example, the first adjustment parameter can also be used to adjust the RRM measurement result obtained by the first terminal device. For example, the adjustment can be made based on the original RRM measurement result obtained by the first terminal device, that is, the adjustment can be increased or decreased based on the original RRM measurement result obtained by the first terminal device to obtain an adjusted RRM measurement result. The above-mentioned original RRM measurement result can be, for example, an RRM measurement result obtained based on a known RRM measurement method.

[0174] The method embodiment of the present application is described in detail above in conjunction with Figures 1 to 4 . The device embodiment of the present application is described in detail below in conjunction with Figures 5 to 7 . It should be understood that the description of the method embodiment corresponds to the description of the device embodiment. Therefore, for parts not described in detail, reference can be made to the above method embodiment.
