Wireless resource management measurement method and communication apparatus

[0001] The present application claims priority to the Chinese patent application No. 202411082834.1, filed on August 7, 2024, and entitled "Wireless resource management measurement method and communication apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] Embodiments of the present application relate to the field of communications, and in particular to a wireless resource management measurement method and a communication apparatus. BACKGROUND

[0003] With the continuous development of communication systems, communication systems gradually penetrate some multimedia services with strong real-time performance and large data capacity requirements, such as extended reality (XR) services and the like.

[0004] The XR service usually has a high requirement for latency, and the data transmission time of the XR service may conflict with the time of radio resource management (RRM) measurement performed by the terminal device, so that the data scheduling of the XR service is limited by the RRM measurement, resulting in a relatively large impact on the performance of the XR service. SUMMARY

[0005] The present application provides a communication method and a communication apparatus to improve the performance of the XR service.

[0006] In a first aspect, embodiments of the present application provide a communication method, which can be applied to the terminal side, such as a terminal or a communication module in the terminal, or a circuit or chip responsible for communication functions in the terminal (such as a modem chip, also known as a baseband chip, or a system on chip (SoC) chip or system in package (SIP) chip containing a modem core). In the present application, a terminal device is taken as an example for description.

[0007] The communication method comprises: receiving first information; and based on the first information, skipping radio resource management (RRM) measurement on N measurement periods in the order from front to back of the measurement periods.

[0008] The first information can be considered as information for indicating skipping RRM measurement on N measurement periods, or the first information can be considered as information for indicating canceling RRM measurement on N measurement periods, or the first information can be considered as information for indicating not performing RRM measurement on N measurement periods.

[0009] Or, alternatively, the first information is described as any one of the following: the first information is used to indicate skipping RRM measurement on N measurement periods, the first information is used to indicate canceling RRM measurement on N measurement periods, and the first information is used to indicate not performing RRM measurement on N measurement periods.

[0010] For example, when the RRM measurement on N measurement periods is skipped in the order of the measurement periods from early to late, the terminal device skips the RRM measurement on N measurement periods in the order of the start time of the measurement period from early to late.

[0011] The technical solution clearly indicates that the terminal device skips the RRM measurement on N measurement periods in the order of the measurement period from early to late. In this way, it helps to reduce the case that the time for data transmission of the XR service is not enough to transmit the data of the XR service due to the behavior of the RRM measurement being given priority. That is, under the technical solution, the network side can prioritize the data transmission of the XR service to improve the performance of the XR service.

[0012] In a possible design, the RRM measurement on N measurement periods is skipped in the order of the start time of the measurement period from early to late, including: skipping the RRM measurement on N measurement periods in the order of the start time of the measurement period from early to late, and in the order of the length of the measurement period from long to short for the measurement periods with the same start time.

[0013] Since the RRM measurement on the measurement period with a longer length has a greater impact on the performance of the XR service, under this implementation manner, when the start times of the measurement periods are the same, the terminal device can skip the RRM measurement on the measurement period that has a greater impact on the performance of the XR service, and correspondingly, the network side has a longer time to transmit the data of the XR service to improve the performance of the XR service.

[0014] In a possible design, the RRM measurement on N measurement periods is skipped in the order of the start time of the measurement period from early to late, including: skipping the RRM measurement on N measurement periods in the order of the start time of the measurement period from early to late, and in the order of the overlap length of the measurement period and the data transmission period from long to short for the measurement periods with the same start time.

[0015] Since the RRM measurement on the measurement period with a longer overlap length of the data transmission period has a greater impact on the performance of the XR service, under this implementation manner, when the start times of the measurement periods are the same, the terminal device can skip the RRM measurement on the measurement period that has a greater impact on the performance of the XR service, and correspondingly, the network side has a longer time to transmit the data of the XR service to improve the performance of the XR service.

[0016] In a possible design, the skipping of the RRM measurement on the N measurement time periods in the order from early to late according to the starting time of the measurement time period comprises: skipping the RRM measurement on the N measurement time periods in the order from early to late according to the starting time of the measurement time period, and in the order from high to low according to the priority of the RRM measurement type for the measurement time periods with the same starting time.

[0017] In this implementation, when the terminal device cannot determine the RRM measurement on the N measurement time periods to be skipped in the order from early to late according to the starting time of the measurement time period, the terminal device can determine the RRM measurement on the N measurement time periods to be skipped according to the priority of the RRM measurement type. In this way, the RRM measurement of different RRM measurement types can be designed based on the size of the impact on the XR service, so that the terminal device can preferentially skip the RRM measurement on the measurement time period that has a greater impact on the performance of the XR service, to improve the performance of the XR service.

[0018] In a second aspect, a communication method is provided. The method can be applied to a terminal side, for example, a terminal or a communication module in the terminal, or a circuit or chip (such as a modem chip, also known as a baseband chip, or a system on chip (SoC) chip or system in package (SIP) chip containing a modem core) responsible for communication functions in the terminal. In this application, a terminal device is taken as an example for description.

[0019] The communication method comprises: receiving second information; and skipping, based on the second information, a radio resource management (RRM) measurement on N measurement time periods in an order from long to short according to a target duration corresponding to the measurement time period.

[0020] The second information can be considered as information for indicating the skipping of the RRM measurement on the N measurement time periods, or the second information can be considered as information for indicating the cancellation of the RRM measurement on the N measurement time periods, or the second information can be considered as information for indicating that no RRM measurement is performed on the N measurement time periods.

[0021] Alternatively, the second information can be described as any of the following: the second information is used to indicate the skipping of the RRM measurement on the N measurement time periods, the second information is used to indicate the cancellation of the RRM measurement on the N measurement time periods, or the second information is used to indicate that no RRM measurement is performed on the N measurement time periods.

[0022] For example, the target duration corresponding to the measurement time period is the duration of the measurement time period; or the target duration corresponding to the measurement time period is the overlapping duration of the measurement time period and a data transmission time period.

[0023] The technical solution clearly defines that the terminal device skips RRM measurement on N measurement periods in the order of the target duration corresponding to the measurement period from long to short. Since the RRM measurement on the measurement period with a longer target duration has a greater impact on the XR service, the terminal device can preferentially skip the RRM measurement on the measurement period with a greater impact on the XR service through the technical solution, and the network side can have a longer time to transmit data of the XR service, thereby improving the performance of the XR service.

[0024] In a possible design, skipping RRM measurement on N measurement periods in the order of the target duration corresponding to the measurement period includes: skipping RRM measurement on N measurement periods in the order of the target duration corresponding to the measurement period from long to short, and in the order of the measurement period from front to back for the measurement period with the same target duration.

[0025] The implementation manner enables the network side to preferentially schedule data transmission of the XR service for the measurement period with the same target duration by skipping RRM measurement on the measurement period earlier, so as to improve the performance of the XR service.

[0026] Optionally, skipping RRM measurement on N measurement periods in the order of the target duration corresponding to the measurement period from long to short, and in the order of the measurement period from front to back for the measurement period with the same target duration includes: skipping RRM measurement on N measurement periods in the order of the target duration corresponding to the measurement period from long to short, and in the order of the starting time of the measurement period from front to back for the measurement period with the same target duration.

[0027] In a possible design, skipping RRM measurement on N measurement periods in the order of the target duration corresponding to the measurement period from long to short includes: skipping RRM measurement on N measurement periods in the order of the target duration corresponding to the measurement period from long to short, and in the order of the priority of the RRM measurement type from high to low for the measurement period with the same target duration.

[0028] The implementation manner enables the terminal device to determine the skipped RRM measurement on N measurement periods through the priority of the RRM measurement type when the terminal device cannot determine the skipped RRM measurement on N measurement periods in the order of the target duration corresponding to the measurement period from long to short. In this way, the RRM measurement of different RRM measurement types can be designed based on the size of the impact on the XR service, so that the RRM measurement on the measurement period with a greater impact on the performance of the XR service can be preferentially skipped, thereby improving the performance of the XR service.

[0029] In a third aspect, the present application provides a communication method, which can be applied to a terminal side, such as a terminal or a communication module in the terminal, or a circuit or chip (such as a modem chip, also known as a baseband chip, or a system on chip (SoC) chip or a system in package (SIP) chip containing a modem core) responsible for communication functions in the terminal. In the present application, the terminal device is taken as an example for description.

[0030] The communication method comprises: receiving third information; and skipping RRM measurement on N measurement periods in a descending order of priority of RRM measurement types based on the third information.

[0031] The third information can be considered as information for indicating skipping RRM measurement on N measurement periods, or the third information can be considered as information for indicating canceling RRM measurement on N measurement periods, or the third information can be considered as information for indicating not performing RRM measurement on N measurement periods.

[0032] Alternatively, the third information can be described as any of the following: the third information is used to indicate skipping RRM measurement on N measurement periods, the third information is used to indicate canceling RRM measurement on N measurement periods, and the third information is used to indicate not performing RRM measurement on N measurement periods.

[0033] The technical solution clearly indicates that the terminal device skips RRM measurement on N measurement periods in a descending order of priority of RRM measurement types, so that RRM measurement of different RRM measurement types can be designed based on the size of the impact on XR services, so as to prioritize skipping RRM measurement on measurement periods with greater impact on XR service performance, thereby improving the performance of XR services.

[0034] In a possible design, skipping RRM measurement on N measurement periods in a descending order of priority of RRM measurement types comprises: skipping RRM measurement on N measurement periods in a descending order of priority of RRM measurement types and in a descending order of measurement periods from front to back for measurement periods of RRM measurement types with the same priority.

[0035] Through this implementation manner, for measurement periods of RRM measurement types with the same priority, the terminal device can skip RRM measurement on earlier measurement periods, and correspondingly, the network side can prioritize scheduling data transmission of XR services, thereby improving the performance of XR services.

[0036] Optionally, the skipping the RRM measurement on the N measurement periods according to the order from high to low of the priority of the RRM measurement type and the order from front to back of the start time of the measurement period of the RRM measurement type with the same priority comprises: skipping the RRM measurement on the N measurement periods according to the order from high to low of the priority of the RRM measurement type and the order from front to back of the length of the measurement period of the RRM measurement type with the same priority.

[0037] In a possible design, the skipping the RRM measurement on the N measurement periods according to the order from high to low of the priority of the RRM measurement type comprises: skipping the RRM measurement on the N measurement periods according to the order from high to low of the priority of the RRM measurement type and the order from long to short of the length of the measurement period of the RRM measurement type with the same priority.

[0038] Since the RRM measurement on the measurement period with the longer length has a greater impact on the XR service performance, with this implementation manner, for the measurement periods of the RRM measurement types with the same priority, the terminal device can skip the RRM measurement on the measurement period with a greater impact on the XR service performance, and correspondingly, the network side has a longer time to transmit the data of the XR service, so as to improve the performance of the XR service.

[0039] In a possible design, the skipping the RRM measurement on the N measurement periods according to the order from high to low of the priority of the RRM measurement type comprises: skipping the RRM measurement on the N measurement periods according to the order from high to low of the priority of the RRM measurement type and the order from long to short of the length of the measurement period of the RRM measurement type with the same priority.

[0040] Since the RRM measurement on the measurement period with the longer length has a greater impact on the XR service performance, with this implementation manner, for the measurement periods of the RRM measurement types with the same priority, the terminal device can skip the RRM measurement on the measurement period with a greater impact on the XR service performance, and correspondingly, the network side has a longer time to transmit the data of the XR service, so as to improve the performance of the XR service.

[0041] In a fourth aspect, a communication method is provided. The method can be applied to a terminal side, such as a terminal or a communication module in the terminal, or a circuit or chip responsible for communication functions in the terminal (such as a modem chip, also known as a baseband chip, or a system on chip (SoC) chip or system in package (SIP) chip containing a modem core), which is not limited in the present application. In the present application, a terminal device is taken as an example for description.

[0042] The communication method comprises: receiving fourth information, the fourth information indicating to skip RRM measurement on M measurement periods of a first RRM measurement type; and based on the fourth information, skipping the RRM measurement on the M measurement periods.

[0043] According to the technical solution, the terminal device is indicated to skip the RRM measurement on the M measurement periods of the first RRM measurement type, so that even if there are multiple RRM measurement types, the terminal device can determine which N measurement periods of RRM measurement should be skipped, thereby improving the performance of the XR service. The multiple RRM measurement types are not described in detail.

[0044] On the other hand, in implementation, the technical solution can determine the RRM measurement type that has a greater impact on the XR service transmission performance as the first RRM measurement type, so that the fourth information indicates the terminal device to skip the RRM measurement on the M measurement periods corresponding to the RRM measurement type that has a greater impact on the XR service transmission performance, thereby achieving the performance of the RRM measurement that has a smaller impact on the XR service transmission, and achieving the compromise effect of the XR service and the terminal device performing RRM measurement.

[0045] In a possible implementation, the fourth information further indicates to skip RRM measurement on P measurement periods of a second RRM measurement type; and the method further comprises: based on the fourth information, skipping the RRM measurement on the P measurement periods of the second RRM measurement type.

[0085] FIG. 1 is a schematic diagram of a communication system 10 according to an embodiment of the present application. It can be understood that the system architecture described in the embodiments of the present application is for more clearly illustrating the technical solutions of the embodiments of the present application, and does not constitute a limitation on the technical solutions provided by the embodiments of the present application.

[0086] As shown in FIG. 1, the communication system 10 includes a radio access network (RAN) 100 and a core network (CN) 200. The RAN 100 includes at least one RAN node (e.g., 110a and 110b in FIG. 1, collectively referred to as 110) and at least one terminal (e.g., 120a-120j in FIG. 1, collectively referred to as 120). Other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in FIG. 1), etc., can also be included in the RAN 100. The terminal 120 is connected to the RAN node 110 in a wireless manner. The RAN node 110 is connected to the core network 200 in a wireless or wired manner. The core network device in the core network 200 and the RAN node 110 in the RAN 100 can be different physical devices respectively, or can be the same physical device integrated with the logical functions of the core network and the logical functions of the radio access network.

[0087] The RAN 100 can be a 3rd generation partnership project (3GPP) related cellular system, such as a 4G, 5G mobile communication system, or a future-oriented evolved system. The RAN 100 can also be an open radio access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (WiFi) system. The RAN 100 can also be a communication system that combines two or more of the above systems.

[0088] The RAN node 110, which can also be referred to as an access network device, a RAN entity, or an access node, etc., constitutes a part of the communication system to help the terminal to implement wireless access. The RAN nodes 110 in the communication system 10 can be nodes of the same type or nodes of different types. In some scenarios, the roles of the RAN node 110 and the terminal 120 are relative, for example, the network element 120i in FIG. 1 can be a helicopter or a drone, which can be configured as a mobile base station. For those terminals 120j that access the RAN 100 through the network element 120i, the network element 120i is a base station; but for the base station 110a, the network element 120i is a terminal. The RAN node 110 and the terminal 120 are sometimes referred to as communication apparatuses, for example, the network elements 110a and 110b in FIG. 1 can be understood as communication apparatuses with base station functions, and the network elements 120a-120j in FIG. 1 can be understood as communication apparatuses with terminal functions.

[0089] In a possible scenario, the RAN node can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a base station in a future mobile communication system, or an access node in a WiFi system, etc. The RAN node can be a macro base station (such as 110a in FIG. 1), a micro base station or an indoor station (such as 110b in FIG. 1), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the RAN node can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, the access network device in vehicle to everything (V2X) technology can be a road side unit (RSU). All or part of the functions of the RAN node in this application can also be implemented by software functions running on hardware, or by virtualized functions instantiated on a platform (such as a cloud platform). The RAN node can also be provided with a communication module, circuit or chip for performing corresponding communication functions, and program instructions for performing corresponding communication functions. The RAN node in this application can also be a logical node, a logical module or software that can implement all or part of the functions of the RAN node.

[0090] In another possible scenario, multiple RAN nodes cooperate to assist a terminal to implement wireless access, and different RAN nodes respectively implement part of the functions of a base station. For example, the RAN node can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately arranged, or can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna processing unit (AAU), or a remote radio head (RRH).

[0091] In different systems, the CU (or CU-CP and CU-UP), DU or RU can also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, the CU can also be referred to as O-CU (open CU), the DU can also be referred to as O-DU, the CU-CP can also be referred to as O-CU-CP, the CU-UP can also be referred to as O-CU-UP, and the RU can also be referred to as O-RU. For the convenience of description, the CU, CU-CP, CU-UP, DU and RU are taken as examples for description in this application. Any one of the CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0092] A terminal can be a device or module with corresponding communication functions and can access the above communication system. The terminal can also be referred to as a terminal device, a user equipment (UE), a mobile station, a mobile terminal, etc. The terminal can be widely used in various scenarios, such as device-to-device (D2D) communication, vehicle-to-everything (V2X) communication, machine-type communication (MTC), internet of things (IOT), virtual reality, augmented reality, industrial control, autonomous driving, remote medical treatment, smart power grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a mechanical arm, a smart home device, a wireless communication module, etc. Embodiments of the present application do not limit the device form of the terminal. The terminal usually has a communication module, circuit or chip for executing corresponding communication functions. The terminal also has program instructions for executing corresponding communication functions.

[0093] In this application, "sending information" can be understood as a device sending information to another device, or also can be understood as a logical module in a device sending information to another logical module. For example, "the access network device sending information" can be understood as the access network device sending information to another device (such as a terminal), or can be understood as a logical module 1 in the access network device sending information to a logical module 2 in the access network device.

[0094] In the present application, "receiving information" can be understood as a device receiving information from another device, or can also be understood as a logical module in a device receiving information from another logical module. For example, "terminal receiving information" can be understood as the terminal receiving information from another device (such as a terminal), or can be understood as a logical module 1 in the terminal receiving information from a logical module 2 in the terminal.

[0095] In the present application, "sending information to (for example, a terminal)" or related illustrations in the drawings can be understood as that the destination of the information is the terminal. It can include directly or indirectly sending information to the terminal. "Receiving information from (for example, a terminal)" or "receiving information from (for example, a terminal)" or "receiving information sent by (for example, a terminal)", or related illustrations in the drawings can be understood as that the source of the information is the terminal, which can include directly or indirectly receiving information from the terminal. The information can be processed as necessary between the source and the destination of the information transmission, such as format change, etc., but the destination can understand the valid information from the source. Similar expressions in the present application can be similarly understood, and will not be repeated here.

[0096] In order to better understand the technical solutions of the embodiments of the present application, some concepts used in the embodiments of the present application are introduced first.

[0097] 1. XR technology

[0098] With the continuous development of communication systems, especially the development of 5G mobile communication systems, the data transmission delay is continuously reduced, and the transmission capacity is getting larger and larger. 5G communication systems gradually penetrate some multimedia services with strong real-time performance and large data capacity requirements, such as video transmission, cloud gaming (CG) and XR, etc. Among them, XR includes virtual reality (VR) and augmented reality (AR).

[0099] XR services have strict delay requirements on the network. For example, in a remote control system, in order to ensure the high fidelity of haptics and remote operation, the sampling rate of haptics information should not be less than 1kHz, and the transmission delay requirement of one sample is 5ms, which brings great challenges to the 5G system.

[0100] 2. RRM measurement based on measurement gap (MG)

[0101] In a mobile cellular network, when a terminal device moves from one cell (base station coverage) to another cell, it needs to be handed over between cells. Before handover, the terminal device needs to perform RRM measurement (also referred to simply as measurement) on the signal of the adjacent cell to determine when it should be handed over. RRM measurement is divided into intra-frequency measurement and inter-frequency measurement.

[0102] Intra-frequency measurement refers to the case where the cell where the terminal device is currently located and the target cell to be measured are on the same carrier frequency point (center frequency point). Inter-frequency measurement refers to the case where the cell where the terminal device is currently located and the target cell are not on the same carrier frequency point.

[0103] In intra-frequency measurement, the terminal device can perform measurement through the reference signal inserted during data transmission, without affecting data transmission and reception. If the terminal device needs to perform inter-frequency measurement, a simple way is to install two types of radio frequency receivers in the terminal device to measure the frequency points of the current cell and the target cell, respectively, but this will cause an increase in cost and mutual interference between different frequency points. Therefore, a measurement gap (also referred to as measurement GAP) is proposed, that is, a part of time is reserved, during which the terminal device will not transmit any other signals or data (can be considered to suspend communication with the serving cell) except for some important signals (for example, signals related to the access process), but will instead tune the receiver to the target cell frequency point to perform inter-frequency measurement, and after the end of this period of time, it will return to the current cell. The duration for which the terminal device suspends communication with the serving cell to measure the inter-frequency neighbor cell or other radio access technology (RAT) neighbor cell is referred to as measurement gap (MG).

[0104] The network device can indicate the terminal device to perform RRM measurement by issuing the configuration information of the measurement gap. The configuration information of the measurement gap includes gapOffset, measurement gap repetition period (MGRP), and measurement gap length (MGL).

[0105] MGRP: represents the period of MG, that is, it can be interpreted as how long there is a MG. For example, the value of MGRP can be 20, 40, 80, 160 ms. For example, if MGRP is 40 ms, it means that there is a MG every 40 ms.

[0106] gapoffset: indicates the offset of the MG, configured by higher layer parameters. The gapoffset points to the starting subframe within the period, with a value ranging from 0 to MGRP-1. For example, if the period is 20 ms, the offset ranges from 0 to 19.

[0107] MGL: specifies the duration of the gap, in milliseconds. The value of MGL can be, for example, 1.5, 3, 3.5, 4, 5.5, and 6 ms. For positioning measurements, 10 and 20 ms are applicable.

[0108] Correspondingly, the terminal device can determine the system frame number (SFN) and the location of the corresponding subframe in which the MG is located based on the configuration information, and then obtain the starting position of the MG to perform MG measurement.

[0109] For example, the SFN and subframe determined by the terminal device satisfy:

[0110] SFN mod T = FLOOR(gapOffset / 10);

[0111] subframe = gapOffset mod 10;

[0112] with T = MGRP / 10.

[0113] Where FLOOR represents rounding down, and mod represents modulo. The meanings of gapOffset and MGRP are as described above and will not be repeated.

[0114] For example, FIG. 2 shows a schematic diagram of the MG when gapOffset is equal to 24, MGRP is equal to 40 milliseconds (msec), and MGL is equal to 4 msec. As shown in FIG. 2, the terminal device can perform a measurement every 40 milliseconds, and each measurement can last for 4 milliseconds.

[0115] 3. Synchronization signal block

[0116] The SSB can also be referred to as a synchronization signal and PBCH block (SS / PBCH block). Specifically, the SSB is composed of three parts: a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcasting channel block (PBCH). When a terminal device moves in a communication system, it continuously performs cell search and measurement based on the SSB, selects a suitable SSB beam, and realizes initial access and mobility management of the terminal device.

[0117] For example, FIG. 3 shows a schematic diagram of subcarrier positions occupied by the PSS, SSS, and PBCH in one SSB. As shown in FIG. 3, one SSB occupies 4 orthogonal frequency division multiplexing (OFDM) symbols in the time domain and 20 resource blocks (RBs) (i.e., 240 subcarriers) in the frequency domain. The first symbol of the SSB is the PSS, and the third symbol is the SSS. Both the PSS and the SSS occupy 127 subcarriers. The PBCH is distributed in the second to fourth symbols of the SSB, and the PBCH occupies 240 subcarriers in the second and fourth symbols. In addition, as shown in FIG. 3, there are some resource elements (REs) that are not used on both sides of the SSS in the third symbol.

[0118] In NR, the SSB is transmitted in the form of beam sweeping. That is, the base station can transmit a beam direction at a certain time, and cover the required directions of the entire cell by transmitting different beams at multiple times.

[0119] 4. RRM measurement based on SSB-based measurement timing configuration (SMTC)

[0120] The cell can transmit the SSB in a periodic scanning manner, and one round of scanning transmits all SSBs in the cell. The SSB scanning period of the cell can be configured (default is 20 ms), and one round of scanning is completed within a half frame (5 ms). The time domain position of the specific SSB (SSB number, SSB symbol position) is related to the SSB frequency and the SCS (Sub-Carrier Spacing).

[0121] In NR, the handover of a terminal device can be based on RRM measurement on SSB. The RRM measurement on SSB is also referred to as SSB measurement. In order to reduce unnecessary measurement power consumption of the terminal device, the concept of SMTC is introduced in NR. The concept of SMTC is as follows:

[0122] The base station can indicate a time window for the terminal device to search for SSB through SMTC configuration. The time window for searching for SSB can be referred to as SMTC window, or also referred to as SMTC time window. The terminal device can perform SSB measurement within the SMTC window, and does not need to perform SSB measurement outside the SMTC window, thereby reducing unnecessary measurement power consumption of the terminal device.

[0123] That is, the SMTC configuration indicates the timing configuration issued by the base station to the terminal device when the terminal device performs SSB-based measurement on a cell. For example, the SMTC configuration includes SMTC period, SMTC duration and SMTC offset. The SMTC period can be considered to indicate how often the terminal device performs SSB measurement, and the SMTC duration can be considered to indicate the duration of performing SSB measurement once.

[0124] XR service usually has a high requirement on latency. However, data transmission of the XR service can conflict with RRM measurement performed by the terminal device, so that data scheduling of the XR service is limited by the RRM measurement, which greatly affects the performance of the XR service.

[0125] The specific type of RRM measurement performed by the terminal device is not limited in the present application. For example, it includes but is not limited to: RRM measurement based on MG, RRM measurement on SSB based on SMTC, RRM measurement on channel state information reference signal (CSI-RS).

[0126] Taking the terminal device-based MG RRM measurement as an example, assuming that the data transmission of the XR service arrives at 60 frames per second (FPS), the MG is configured as Pattern 0 in Table 1 (the period of the configured MG is 40 ms, and the MGL is 6 ms), that is, the frame arrival period of the XR service is 16.67 ms, the terminal device performs RRM measurement once every 40 ms, and the duration of one RRM measurement is 6 ms, then as shown in FIG. 4, in the fourth 16.67 ms duration and the sixth 16.67 ms duration, because the terminal device needs to perform inter-frequency measurement, the base station will not schedule the XR service data for the terminal device in the time period during which the terminal device performs inter-frequency measurement, so that the data received by the terminal device in the fourth 16.67 ms duration and the sixth 16.67 ms duration is affected, resulting in a significant decrease in XR capacity and a great impact on the performance of the XR service.

[0127] To cancel the above-mentioned scheduling restriction caused by RRM measurement, one implementation is that the base station sends downlink control information (DCI) to the terminal device to indicate skipping RRM measurement on the next N measurement periods, where N is a positive integer greater than or equal to 1.

[0128] However, through analysis, it is found that if there are multiple types of RRM measurement of the terminal device, when the base station sends DCI to the terminal device to indicate skipping RRM measurement on the next N measurement periods, there may be a situation that the terminal device cannot determine which N measurement periods of RRM measurement to skip next.

[0129] For example, the terminal device needs to perform three types of RRM measurement, which are MG-based RRM measurement, SMTC-based RRM measurement, and CSI-RS-based RRM measurement. In a certain time period, the time relationship between the data transmission of the XR service and the three types of RRM measurement performed by the terminal device is shown in (a) of FIG. 5. At this time, if the base station sends DCI to indicate skipping RRM measurement on the next 4 measurement periods at the position shown in (a) of FIG. 5, the terminal device cannot determine whether it should skip the RMM measurement on the 4 measurement periods shown in (b) of FIG. 5, or skip the RMM measurement on the 4 measurement periods shown in (c) of FIG. 5, or skip the RMM measurement on the 4 measurement periods shown in (d) of FIG. 5.

[0130] Therefore, the present application provides a communication method and a communication device, so that the terminal device can determine the N measurement periods of RRM measurement to skip.

[0131] The communication method provided by the embodiments of the present application is described below in combination with the drawings. It can be understood that the access network device and the terminal device are taken as examples of the execution subject of the interaction in the present application, but the present application does not limit the execution subject of the interaction. For example, the method executed by the access network device in the present application can also be implemented by a module (such as a circuit, a chip or a chip system, etc.) in the access network device, or a logical node, a logical module or software capable of implementing all or part of the functions of the access network device; the method executed by the terminal device in the present application can also be implemented by a communication module in the terminal device or a circuit or a chip (such as a modem chip (also known as a baseband chip), or a SoC chip containing a modem core, or a SIP chip) responsible for the communication function in the terminal.

[0132] FIG. 6 is a schematic flowchart of the communication method provided by the present application. As shown in FIG. 6, the method comprises:

[0133] S610, the access network device sends first information; correspondingly, the terminal device receives the first information.

[0134] In the present embodiment, the first information can be considered as information for indicating skipping RRM measurement on N measurement periods, or the first information can be considered as information for indicating canceling RRM measurement on N measurement periods, or the first information can be considered as information for indicating not performing RRM measurement on N measurement periods.

[0135] Alternatively, from another perspective, the first information can be described as any of the following: the first information is used for indicating skipping RRM measurement on N measurement periods, the first information is used for indicating canceling RRM measurement on N measurement periods, and the first information is used for indicating not performing RRM measurement on N measurement periods.

[0136] It is explained herein that the present embodiment does not limit the implementation manner of how the first information specifically indicates skipping RRM measurement on N measurement periods.

[0137] For example, in one implementation manner, the first information can be 1 bit, and the 1 bit indicates skipping RRM measurement on 1 measurement period by default, that is, at this time, N can be considered to be equal to 1.

[0138] For example, in another implementation manner, the first information can be 1 bit, and the 1 bit indicates skipping RRM measurement on N measurement periods, where N is configured by the access network device through an RRC message.

[0139] For example, in yet another implementation manner, the first information can be a bitmap, and the bitmap indicates skipping RRM measurement on N measurement periods.

[0140] For example, in yet another implementation, the first information can be to indicate skipping RRM measurement over N measurement periods in a log2(N) bit manner. For example, 2 bits are used to indicate skipping RRM measurement over 4 measurement periods, and 3 bits are used to indicate skipping RRM measurement over 8 measurement periods.

[0141] At S620, the terminal device skips RRM measurement over N measurement periods in a front-to-back order of the measurement periods based on the first information.

[0142] It is explained herein that the embodiment does not limit the specific type of RRM measurement performed by the terminal device. The type of RRM measurement performed by the terminal device is also referred to as RRM measurement type. For example, the RRM measurement type includes but is not limited to: RRM measurement based on MG, RRM measurement on SSB based on SMTC, RRM measurement on CSI-RS.

[0143] For example, before the access network device sends the first information to the terminal device, the access network device sends configuration information of RRM measurement to be performed by the terminal device to the terminal device, and correspondingly, the terminal device determines the measurement period, measurement period, and measurement period of the RRM measurement to be performed based on the configuration information.

[0144] In the embodiment, the measurement period can also be referred to as measurement window, measurement time window, measurement time window, and mainly indicates the period of performing RRM measurement. Correspondingly, the measurement period can also be referred to as the period of the measurement window, the period of the measurement time window, and the period of the measurement time window, and mainly indicates how long to perform measurement. The duration of the measurement period can also be referred to as the duration of the measurement window, or the duration of the measurement time window, or the duration of the measurement time window, and mainly indicates the duration of performing RRM measurement by the terminal device.

[0145] For example, the type of RRM measurement to be performed by the terminal device includes MG-based RRM measurement (also referred to as MG measurement), SMTC-based RRM measurement (also referred to as SMTC measurement), the access network device configures the configuration information of MG measurement and the configuration information of SMTC measurement to the terminal device, and then the terminal device determines the measurement window, measurement window period, and duration of the measurement window period based on the configuration information of the MG measurement when performing the MG measurement, and determines the measurement window, measurement window period, and duration of the measurement window period based on the configuration information of the SMTC measurement when performing the SMTC measurement.

[0146] In this embodiment, after receiving the first information, the terminal device skips RRM measurement on N measurement periods in the order from the front to the back of the measurement periods. Alternatively, it can also be explained as any one of the following: the terminal device cancels RRM measurement on N measurement periods in the order from the front to the back of the measurement periods, or the terminal device does not perform RRM measurement on the first N measurement periods in the order from the front to the back of the measurement periods. That is, in this embodiment, when determining the N measurement periods that should be skipped, the terminal device is determined based on the order from the front to the back of the measurement periods.

[0147] Optionally, after receiving the first information, the terminal device skips RRM measurement on N measurement periods in the order from the front to the back of the measurement periods within the first period. For example, the first period can be predefined by a protocol, or the first period can also be configured to the terminal device by the network device. Optionally, the value of the first period is the packet delay budget (PDB) of the XR service.

[0148] For example, the terminal device skips RRM measurement on N measurement periods based on the order from the front to the back of the starting time of the measurement periods. That is, the terminal device determines the order of the measurement periods based on the starting time of the measurement periods. It can be understood that determining the order of the measurement periods based on the starting time of the measurement periods is only an example, but does not constitute a limitation of this embodiment. For example, the terminal device can also determine the order of the measurement periods based on other times of the measurement periods.

[0149] For example, in an implementation manner, the starting time can also be replaced by the middle time of the measurement period. Correspondingly, the terminal device skips RRM measurement on N measurement periods in the order from the front to the back of the starting time of the measurement periods, which is replaced by: the terminal device skips RRM measurement on N measurement periods in the order from the front to the back of the middle time of the measurement periods.

[0150] For example, in another implementation manner, the starting time can also be replaced by the end time of the measurement period. Correspondingly, the terminal device skips RRM measurement on N measurement periods in the order from the front to the back of the starting time of the measurement periods, which is replaced by: the terminal device skips RRM measurement on N measurement periods in the order from the front to the back of the end time of the measurement periods.

[0151] Exemplarily, assuming that data transmission of the XR service arrives at the terminal device at 60 FPS, i.e., the frame arrival period of the XR service is 16.67 ms, the packet delay budget (PDB) of the XR service is 10 ms, the RRM measurement types performed by the terminal device include MG-based RRM measurement, SMTC-based RRM measurement, and CSI-RS-based RRM measurement, and in a certain period of time, the various RRM measurements performed by the terminal device and the data transmission of the XR service are schematically shown in FIG. 7. In this scenario:

[0152] 1) If the access network device sends the first information to indicate skipping RRM measurement on 2 measurement periods at the position shown in FIG. 7, the terminal device will skip RRM measurement on the two measurement periods of measurement period 7 and measurement period 4;

[0153] 2) If the access network device sends the first information to indicate skipping RRM measurement on 3 measurement periods at the position shown in FIG. 7, the terminal device will skip RRM measurement on the three measurement periods of measurement period 7, measurement period 4, and measurement period 8.

[0154] It can be understood that, by the technical solution provided in this embodiment, since the terminal device skips RRM measurement on N measurement periods in the order from front to back of the measurement periods, the network device can perform data transmission of the XR service on the N measurement periods skipped by the terminal device, and under this technical solution, it is helpful to reduce the problem that the remaining time after the measurement time is removed within the delay requirement when the RRM measurement behavior is given priority, and the remaining time is not enough to guarantee the transmission of the XR service, and thus the performance of the XR service can be improved.

[0155] In addition, under this technical solution, since it is specified that the terminal device skips RRM measurement on N measurement periods in the order from front to back of the measurement periods, even if there are multiple RRM measurement types of RRM measurement, it is helpful for the terminal device to determine which N measurement periods of RRM measurement should be skipped.

[0156] As an optional embodiment, when the terminal device skips RRM measurement on N measurement periods in the order from front to back of the starting time of the measurement periods, it includes: the terminal device skips RRM measurement on N measurement periods in the order from front to back of the starting time of the measurement periods, and in the order from long to short of the time length of the measurement periods for the measurement periods with the same starting time. That is, after receiving the first information, the terminal device takes the order from front to back of the starting time of the measurement periods as the principle, and then determines the RRM measurement on N measurement periods that should be skipped in the order from long to short of the time length (i.e., the duration of the measurement period) of the measurement periods for the measurement periods with the same starting time.

[0157] Similarly, it can be understood that the starting time herein can also be replaced by other time. For example, the starting time can be replaced by the middle time. That is, the terminal device skips the RRM measurement on the N measurement periods in the order of the starting time of the measurement period from early to late, and in the order of the length of the measurement period from long to short for the measurement periods with the same starting time. For another example, the starting time can be replaced by the end time. That is, the terminal device skips the RRM measurement on the N measurement periods in the order of the end time of the measurement period from early to late, and in the order of the length of the measurement period from long to short for the measurement periods with the same end time.

[0158] Exemplarily, it is assumed that the data transmission of the XR service arrives at the terminal device at 60 FPS, that is, the frame arrival period of the XR service is 16.67 ms, the PDB of the XR service is 10 ms, the RRM measurement types performed by the terminal device include the MG-based RRM measurement, the SMTC-based RRM measurement, and the CSI-RS-based RRM measurement, and the schematic diagram of the time of various RRM measurements performed by the terminal device and the data transmission of the XR service in a period is as shown in FIG. 8. In this scenario:

[0159] 1) If the access network device sends the first information indicating skipping the RRM measurement on 2 measurement periods at the position shown in FIG. 8, then the terminal device will skip the RRM measurement on the measurement period 7 and the measurement period 4 in the order of the starting time of the measurement period from early to late, and in the order of the duration of the measurement period from long to short for the measurement periods with the same starting time.

[0160] 2) If the access network device sends the first information indicating skipping the RRM measurement on 3 measurement periods at the position shown in FIG. 8, then the terminal device will skip the RRM measurement on the measurement period 7, the measurement period 4, and the measurement period 1 in the order of the starting time of the measurement period from early to late, and in the order of the duration of the measurement period from long to short for the measurement periods with the same starting time. As shown in FIG. 8, the starting time of the measurement period 8 included in the CSI-RS-based RRM measurement and the measurement period 1 included in the MG-based RRM measurement is the same, but the duration of the measurement period 1 is longer than that of the measurement period 1, so the terminal device skips the RRM measurement on the measurement period 1.

[0161] As an optional embodiment, when the terminal device skips the RRM measurement on the N measurement time periods in the order from early to late of the starting time of the measurement time period, it comprises: the terminal device skips the RRM measurement on the N measurement time periods in the order from early to late of the starting time of the measurement time period, and in the order from long to short of the overlapping duration of the measurement time period and the data transmission time period for the measurement time periods with the same starting time.

[0162] Optionally, when the terminal device skips the RRM measurement on the N measurement time periods in the order from early to late of the starting time of the measurement time period, it comprises: the terminal device skips the RRM measurement on the N measurement time periods in the order from early to late of the starting time of the measurement time period, and in the order from long to short of the overlapping duration of the measurement time period and the data transmission time period for the measurement time periods with the same starting time. That is, after receiving the first information, the terminal device takes the order from early to late of the starting time of the measurement time period as the principle, and then determines the RRM measurement on the N measurement time periods that should be skipped in the order from long to short of the overlapping duration of the measurement time period and the data transmission time period for the measurement time periods with the same starting time.

[0163] It should be noted that the data transmission time period refers to the time window of data transmission, for example, the time window of 10ms PDB as shown in FIGS. 7-8.

[0164] Similarly, it can be understood that the starting time here can be replaced by other time. For example, the starting time can be replaced by the middle time, that is, the terminal device skips the RRM measurement on the N measurement time periods in the order from early to late of the middle time of the measurement time period, and in the order from long to short of the overlapping duration of the measurement time period and the data transmission time period for the measurement time periods with the same middle time. For another example, the starting time can be replaced by the end time. That is, the terminal device skips the RRM measurement on the N measurement time periods in the order from early to late of the end time of the measurement time period, and in the order from long to short of the overlapping duration of the measurement time period and the data transmission time period for the measurement time periods with the same end time.

[0165] Still taking the various RRM measurements and data transmission of XR service performed by the terminal device shown in FIG. 8 as an example, if the access network device sends the first information indicating to skip the RRM measurements on 3 measurement periods at the positions shown in FIG. 8, the terminal device will skip the RRM measurements on the 3 measurement periods of measurement period 7, measurement period 4 and measurement period 1. As shown in FIG. 8, the starting time of the measurement period 8 included in the CSI-RS based RRM measurement and the measurement period 1 included in the MG based RRM measurement are the same, but the length of the overlapping part of the measurement period 1 and the time period for transmitting the XR service is longer than the length of the overlapping part of the measurement period 8 and the time period for transmitting the XR service, so the terminal device skips the RRM measurement on the measurement period 1.

[0166] As an optional embodiment, when the terminal device skips the RRM measurements on N measurement periods in the order of the starting time of the measurement periods from early to late, it includes: the terminal device skips the RRM measurements on N measurement periods in the order of the starting time of the measurement periods from early to late, and for the measurement periods with the same starting time, in the order of the length of the measurement periods from long to short, and for the measurement periods with the same starting time and the same overlapping length, in the order of the priority of the measurement types from high to low. Similarly, it can be understood that the starting time here can be replaced by other time. For example, the starting time can be replaced by the middle time. Details are omitted.

[0167] Optionally, the terminal device skips the RRM measurements on N measurement periods in the order of the starting time of the measurement periods from early to late, including: the terminal device skips the RRM measurements on N measurement periods in the order of the starting time of the measurement periods from early to late, and for the measurement periods with the same starting time, in the order of the priority of the RRM measurement types from high to low.

[0168] That is, after receiving the first information, the terminal device takes the order of the starting time of the measurement periods from early to late as the principle, and then determines the N measurement periods on which the RRM measurements should be skipped for the measurement periods with the same starting time in the order of the priority of the RRM measurement types from high to low.

[0169] Similarly, it can be understood that the starting time here can be replaced by other time. For example, the starting time can be replaced by the middle time. That is, the terminal device skips the RRM measurements on N measurement periods in the order of the middle time of the measurement periods from early to late, and for the measurement periods with the same middle time, in the order of the priority of the RRM measurement types from high to low. For another example, the starting time can be replaced by the end time. That is, the terminal device skips the RRM measurements on N measurement periods in the order of the end time of the measurement periods from early to late, and for the measurement periods with the same end time, in the order of the priority of the RRM measurement types from high to low.

[0170] For example, assuming that the data transmission of the XR service reaches the terminal device at 60 FPS, i.e., the frame arrival period of the XR service is 16.67 ms, the PDB of the XR service is 10 ms, the RRM measurement types performed by the terminal device include MG-based RRM measurement, SMTC-based RRM measurement, and CSI-RS-based RRM measurement, and the time diagram of the various RRM measurements performed by the terminal device and the data transmission of the XR service in a certain period of time is as shown in FIG. 8. In this scenario:

[0171] 1) If the RRM measurement priorities of the MG-based RRM measurement, the SMTC-based RRM measurement, and the CSI-RS-based RRM measurement are from high to low, when the access network device sends the first information indicating skipping RRM measurement in the three measurement periods as shown in FIG. 8, the terminal device will skip the RRM measurement in the three measurement periods of measurement period 7, measurement period 4, and measurement period 1. Understandably, the starting time of measurement period 8 included in the CSI-RS-based RRM measurement and measurement period 1 included in the MG-based RRM measurement is the same, but the priority of the RRM measurement type corresponding to measurement period 1 is higher than the priority of the RRM measurement type corresponding to measurement period 8, so the terminal device skips the RRM measurement in measurement period 1.

[0172] 2) If the RRM measurement priorities of the MG-based RRM measurement, the SMTC-based RRM measurement, and the CSI-RS-based RRM measurement are from low to high, the terminal device will determine to skip the RRM measurement in the three measurement periods of measurement period 7, measurement period 4, and measurement period 8 shown in FIG. 8. Understandably, the starting time of measurement period 8 included in the CSI-RS-based RRM measurement and measurement period 1 included in the MG-based RRM measurement is the same, but the priority of the RRM measurement type corresponding to measurement period 8 is higher than the priority of the RRM measurement type corresponding to measurement period 1, so the terminal device skips the RRM measurement in measurement period 8.

[0173] As an optional embodiment, when the terminal device skips the RRM measurement in N measurement periods in the order of the starting time of the measurement periods from front to back, it includes: the terminal device skips the RRM measurement in N measurement periods in the order of the starting time of the measurement periods from front to back, and in the order of the priority of the RRM measurement type from high to low for the measurement periods with the same starting time, and in the order of the length of the measurement periods from long to short for the measurement periods with the same starting time and the same priority of the RRM measurement type. Alternatively,

[0174] When the terminal device skips RRM measurement on N measurement time periods in the order from early to late according to the starting time of the measurement time period, the method comprises: the terminal device skips RRM measurement on N measurement time periods in the order from early to late according to the starting time of the measurement time period, and in the order from high to low according to the priority of the RRM measurement type for the measurement time periods with the same starting time, and in the order from long to short according to the overlapping length of the measurement time period and the period of data transmission for the measurement time periods with the same starting time and the same priority of the RRM measurement type.

[0175] For example, it is assumed that the data transmission of the XR service reaches the terminal device at 60 FPS, that is, the frame arrival period of the XR service is 16.67 ms, the PDB of the XR service is 10 ms, the RRM measurement types performed by the terminal device include MG-based RRM measurement, SMTC-based RRM measurement, and CSI-RS-based RRM measurement, and the schematic diagram of the time of various RRM measurements performed by the terminal device and the data transmission of the XR service in a period of time is shown in FIG. 8. In this scenario:

[0176] If the RRM measurement priorities of the MG-based RRM measurement and the CSI-RS-based RRM measurement are the same, when the access network device sends the first information to indicate skipping RRM measurement on 3 measurement time periods at the position shown in FIG. 8, if the terminal device skips RRM measurement on the measurement time periods in the order from early to late according to the starting time of the measurement time period, in the order from high to low according to the priority of the RRM measurement type for the measurement time periods with the same starting time, and in the order from long to short according to the length of the measurement time period for the measurement time periods with the same starting time and the same priority of the RRM measurement type, the terminal device will skip RRM measurement on the measurement time period 7, the measurement time period 4, and the measurement time period 1. It can be understood that the starting time of the measurement time period 1 and the measurement time period 8 and the corresponding RRM measurement priorities are the same, but the duration of the measurement time period 1 is longer than the duration of the measurement time period 8, so the terminal device skips RRM measurement on the measurement time period 1.

[0177] The above describes the implementation method of how the terminal device skips RRM measurement on N measurement time periods in the order from early to late according to the measurement time period.

[0178] Next, another communication method provided by the present application is described in combination with FIG. 9. As shown in FIG. 9, the method comprises:

[0179] S910, the access network device sends second information.

[0180] The second information in this embodiment is the first information in the embodiment shown in FIG. 6, that is, the second information can be replaced by the first information. The description of the first information can refer to the description in the embodiment of FIG. 6, which is not described here.

[0181] S920, the terminal device skips RRM measurement on N measurement periods in a sequence from long to short of target durations corresponding to the measurement periods based on the second information.

[0182] It is explained that the embodiment does not limit the specific type of RRM measurement performed by the terminal device. The type of RRM measurement is also referred to as RRM measurement type. For example, the RRM measurement type includes but is not limited to: RRM measurement based on MG, RRM measurement on SSB based on SMTC, RRM measurement on CSI-RS. For example, before the access network device sends the second information to the terminal device, the access network device sends configuration information of RRM measurement to be performed by the terminal device to the terminal device, and correspondingly, the terminal device determines the measurement period, measurement period, and the like. information such as the duration of the measurement period of the RRM measurement to be performed according to the configuration information. The detailed description of this part can be referred to the description in S620 in the embodiment of FIG. 6, which will not be repeated here.

[0183] In the embodiment, after receiving the second information, the terminal device skips RRM measurement on N measurement periods in a sequence from long to short of target durations corresponding to the measurement periods. Or it can also be explained as any one of the following: the terminal device cancels RRM measurement on the first N measurement periods in a sequence from long to short of target durations corresponding to the measurement periods, and the terminal device does not perform RRM measurement on the first N measurement periods in a sequence from long to short of target durations corresponding to the measurement periods.

[0184] That is, in the embodiment, the terminal device determines the N measurement periods that should be skipped based on a sequence from long to short of target durations corresponding to the measurement periods.

[0185] Optionally, after receiving the second information, the terminal device skips RRM measurement on N measurement periods in a sequence from front to back of the measurement periods within the first period within the first period. The concept of the first period can be referred to the description in the embodiment of FIG. 6, which will not be repeated here.

[0186] In one implementation, the target duration corresponding to the measurement period is the duration of the measurement period, that is, the target duration corresponding to the measurement period is the duration of the measurement time window or the duration of the measurement time window.

[0187] In another implementation, the target duration corresponding to the measurement period is the overlap duration of the measurement period and the data transmission period. The data transmission period is a time window for transmitting service data.

[0188] For example, if a certain measurement period is 6ms, and the overlap part with a certain data transmission period occupies 3ms, then for the certain measurement period, the corresponding target duration is 6ms or 3ms.

[0189] For example, it is assumed that the data transmission of the XR service reaches the terminal device at 60 FPS, i.e., the frame arrival period of the XR service is 16.67 ms, the PDB of the XR service is 10 ms, the RRM measurement types performed by the terminal device include MG-based RRM measurement, SMTC-based RRM measurement, and CSI-RS-based RRM measurement, the MG-based RRM measurement includes a measurement period with a duration of 6 ms, the SMTC-based RRM measurement includes a measurement period with a duration of 2 ms, and the CSI-RS-based RRM measurement includes a measurement period with a duration of 1 ms. In a certain period of time, the time diagram of various RRM measurements performed by the terminal device and the data transmission of the XR service is shown in FIG. 10. In this scenario:

[0190] If the access network device sends the second information to indicate skipping RRM measurement in the two measurement periods shown in FIG. 10, if the terminal device skips RRM measurement in the two measurement periods of measurement period 1 and measurement period 4 within 10 ms based on the order of the duration of the measurement period from long to short or based on the order of the overlapping duration from long to short.

[0191] It can be understood that, by the technical solution provided in this embodiment, because the terminal device skips RRM measurement in N measurement periods according to the order of the target duration of the measurement period from long to short, the network device can perform data transmission of the XR service in the N measurement periods skipped by the terminal device, so the reliability of the XR service can be preferentially guaranteed, and the problem that the remaining time after removing the measurement time within the delay requirement may not be sufficient to guarantee the transmission of the XR service when the service transmission is performed after the measurement time due to the priority of the RRM measurement behavior. In addition, under this technical solution, because it is specified that the terminal device skips RRM measurement in N measurement periods according to the order of the target duration of the measurement period from long to short, even if there are multiple RRM measurement types of RRM measurement, it is also helpful for the terminal device to determine which N measurement periods of RRM measurement should be skipped.

[0192] As an optional embodiment, the terminal device skips RRM measurement in N measurement periods according to the order of the target duration of the measurement period from long to short, including: the terminal device skips RRM measurement in N measurement periods according to the order of the target duration of the measurement period from long to short, and the order of the measurement period from front to back for the measurement periods with the same target duration. That is, after receiving the second information, the terminal device takes the order of the target duration of the measurement period from long to short as the principle, and then determines the RRM measurement in N measurement periods that should be skipped according to the order of the measurement period from front to back for the measurement periods with the same target duration.

[0193] wherein, for the measurement periods with the same target duration, the order is from the front to the back of the measurement periods, e.g., including the order of the starting time of the measurement periods for the measurement periods with the same target duration from the front to the back of the measurement periods.

[0194] For example, after receiving the second information, the terminal device determines the RRM measurement on the N measurement periods that should be skipped in the order of the duration of the measurement periods from long to short, and then in the order of the measurement periods from the front to the back of the measurement periods for the measurement periods with the same duration.

[0195] For example, after receiving the second information, the terminal device determines the RRM measurement on the N measurement periods that should be skipped in the order of the overlap duration of the measurement periods from long to short, and then in the order of the measurement periods from the front to the back of the measurement periods for the measurement periods with the same overlap duration.

[0196] For example, assuming that the data transmission of the XR service arrives at the terminal device at 60 FPS, i.e., the frame arrival period of the XR service is 16.67 ms, the PDB of the XR service is 10 ms, the RRM measurement types performed by the terminal device include MG-based RRM measurement, SMTC-based RRM measurement, and CSI-RS-based RRM measurement, and the time diagram of the various RRM measurements performed by the terminal device and the data transmission of the XR service in a certain period of time is as shown in FIG. 7. In this scenario, if the duration of the measurement period included in the MG-based RRM measurement is 6 ms, the duration of the measurement period included in the SMTC-based RRM measurement and the duration of the measurement period included in the CSI-RS-based RRM measurement are the same and less than 6 ms. Then:

[0197] 1) When the access network device sends the second information indicating skipping of RRM measurement on 2 measurement periods at the position shown in FIG. 7, if the terminal device determines the RRM measurement on the measurement periods in the order of the duration of the measurement periods, and in the order of the starting time of the measurement periods from the front to the back of the measurement periods for the measurement periods with the same duration, the terminal device will skip the RRM measurement on the measurement period 1 and the measurement period 7.

[0198] 2) When the access network device sends the second information indicating skipping of RRM measurement on 3 measurement periods at the position shown in FIG. 7, if the terminal device determines the RRM measurement on the measurement periods in the order of the duration of the measurement periods, and in the order of the starting time of the measurement periods from the front to the back of the measurement periods for the measurement periods with the same duration, the terminal device will skip the RRM measurement on the measurement period 1, the measurement period 7, and the measurement period 4.

[0199] As an optional embodiment, when the terminal device skips RRM measurement on N measurement periods in the order of the target duration corresponding to the measurement period from long to short, it includes: the terminal device skips RRM measurement on N measurement periods in the order of the target duration corresponding to the measurement period from long to short, and in the order of the starting time from early to late for the measurement period with the same target duration, and in the order of the priority of the measurement type from high to low for the measurement period with the same target duration and the same starting time. Optionally, the starting time here can also be replaced by the middle time or other time, etc.

[0200] As an optional embodiment, when the terminal device skips RRM measurement on N measurement periods in the order of the target duration corresponding to the measurement period from long to short, it includes: the terminal device skips RRM measurement on N measurement periods in the order of the target duration corresponding to the measurement period from long to short, and in the order of the priority of the RRM measurement type from high to low for the measurement period with the same target duration. That is, after receiving the second information, the terminal device takes the order of the target duration corresponding to the measurement period from long to short as the principle, and then determines the RRM measurement on N measurement periods that should be skipped in the order of the priority of the RRM measurement type from high to low for the measurement period with the same target duration.

[0201] For example, after receiving the second information, the terminal device takes the order of the duration of the measurement period from long to short as the principle, and then determines the RRM measurement on N measurement periods that should be skipped in the order of the priority of the RRM measurement type from high to low for the measurement period with the same duration.

[0202] For example, after receiving the second information, the terminal device takes the order of the overlap duration corresponding to the measurement period from long to short as the principle, and then determines the RRM measurement on N measurement periods that should be skipped in the order of the priority of the RRM measurement type from high to low for the measurement period with the same overlap duration.

[0203] For example, after receiving the second information, the terminal device takes the order of the overlap duration corresponding to the measurement period from long to short as the principle, and then determines the RRM measurement on N measurement periods that should be skipped in the order of the priority of the RRM measurement type from high to low for the measurement period with the same overlap duration.

[0204] 1) If the RRM measurement priority of the RRM measurement based on MG, the RRM measurement based on SMTC and the RRM measurement based on CSI-RS is from high to low, when the access network device sends the first information indicating skipping the RRM measurement on two measurement periods in the position shown in FIG. 7, if the terminal device takes the duration of the measurement period as the principle from long to short, and then for the measurement periods with the same duration, takes the priority of the RRM measurement type from high to low, then the terminal device will determine to skip the RRM measurement on the measurement period 1 and the measurement period 4.

[0205] 2) If the RRM measurement priority of the RRM measurement based on MG, the RRM measurement based on SMTC and the RRM measurement based on CSI-RS is from low to high, when the access network device sends the first information indicating skipping the RRM measurement on two measurement periods in the position shown in FIG. 7, if the terminal device takes the duration of the measurement period as the principle from long to short, and then for the measurement periods with the same duration, takes the priority of the RRM measurement type from high to low, then the terminal device will determine to skip the RRM measurement on the measurement period 1 and the measurement period 7. When the access network device sends the first information indicating skipping the RRM measurement on three measurement periods in the position shown in FIG. 7, then the terminal device will determine to skip the RRM measurement on the measurement period 1, the measurement period 7 and the measurement period 8.

[0206] As an optional embodiment, the terminal device skips the RRM measurement on N measurement periods according to the target duration corresponding to the measurement period from long to short, including: the terminal device skips the RRM measurement on N measurement periods according to the target duration corresponding to the measurement period from long to short, and for the measurement periods with the same target duration, according to the priority of the RRM measurement type from high to low, and for the measurement periods with the same target duration and the same priority of the RRM measurement type, according to the starting time of the measurement period from front to back. Optionally, the starting time here can be replaced by the middle time or other time, etc.

[0207] Exemplarily, it is assumed that the data transmission of the XR service arrives at the terminal device at 60 FPS, i.e., the frame arrival period of the XR service is 16.67 ms, the PDB of the XR service is 10 ms, the RRM measurement types performed by the terminal device include MG-based RRM measurement, SMTC-based RRM measurement, and CSI-RS-based RRM measurement, and the time diagram of the various RRM measurements performed by the terminal device and the data transmission of the XR service in a certain period of time is as shown in FIG. 7. In this scenario, the duration of the measurement period included in the MG-based RRM measurement is 6 ms, and the duration of the measurement period included in the SMTC-based RRM measurement and the duration of the measurement period included in the CSI-RS-based RRM measurement are the same and less than 6 ms. Then:

[0208] If the priority of the MG-based RRM measurement is the highest, and the RRM measurement priorities of the SMTC-based RRM measurement and the CSI-RS-based RRM measurement are the same, when the access network device sends the first information to indicate skipping RRM measurement in 2 measurement periods at the position shown in FIG. 7, if the terminal device follows the order from long to short of the target duration corresponding to the measurement period, and the order from high to low of the priority of the RRM measurement type for the measurement periods with the same target duration, and the order from front to back of the starting time of the measurement period for the measurement periods with the same target duration and the same priority of the RRM measurement type, the terminal device will determine to skip RRM measurement in measurement period 1 and measurement period 7.

[0209] In the above, the implementation method in which the terminal device skips RRM measurement in N measurement periods according to the order from long to short of the target duration corresponding to the measurement period is introduced in combination with FIG. 9.

[0210] Next, the schematic flowchart of another communication method of the present application is introduced in combination with FIG. 11. As shown in FIG. 11, the method includes:

[0211] S1110, the access network device sends third information.

[0212] The third information in this embodiment is the first information in the embodiment shown in FIG. 6, i.e., the third information can be replaced by the first information. The description of the first information can refer to the description in the embodiment of FIG. 6, which is not described here.

[0213] S1120, the terminal device skips RRM measurement in N measurement periods according to the order from high to low of the priority of the RRM measurement type based on the third information.

[0214] It is explained that the embodiment does not limit the specific type of RRM measurement performed by the terminal device. The type of RRM measurement is also referred to as the RRM measurement type. For example, the RRM measurement type includes but is not limited to: RRM measurement based on MG, RRM measurement of SSB based on SMTC, and RRM measurement of CSI-RS. For example, before the access network device sends the third information to the terminal device, the access network device sends configuration information of RRM measurement that the terminal device needs to perform to the terminal device, and correspondingly, the terminal device determines the measurement period, the measurement period, and the length of the measurement period according to the configuration information. The detailed description of this part can be referred to the description in S620 in the embodiment of FIG. 6, which will not be repeated here.

[0215] In the embodiment, after the terminal device receives the third information, the terminal device skips the RRM measurement on the N measurement periods in the order of the priority of the RRM measurement type from high to low. Or it can also be explained as any one of the following: the terminal device cancels the RRM measurement on the N measurement periods in the order of the priority of the RRM measurement type from high to low, and the terminal device does not perform the RRM measurement on the first N measurement periods in the order of the priority of the RRM measurement type from high to low.

[0216] That is, in the embodiment, the terminal device determines the N measurement periods that should be skipped based on the order of the priority of the RRM measurement type from high to low.

[0217] Optionally, after the terminal device receives the third information, the terminal device skips the RRM measurement on the N measurement periods in the first period in the order of the measurement period from front to back. The concept of the first period can be referred to the description in the embodiment of FIG. 6, which will not be repeated here.

[0218] Exemplarily, it is assumed that the data transmission of the XR service reaches the terminal device at 60FPS, that is, the frame arrival period of the XR service is 16.67ms, the PDB of the XR service is 10ms, the RRM measurement type performed by the terminal device includes RRM measurement based on MG, RRM measurement based on SMTC, and RRM measurement based on CSI-RS, and in a certain period, the time diagram of various RRM measurements performed by the terminal device and the data transmission of the XR service is shown in FIG. 7. In this scenario:

[0219] 1) If the access network device sends the first information to indicate skipping the RRM measurement on 2 measurement periods at the position shown in FIG. 7, if the first period is the period of the PDB window, if the priority of the RRM measurement based on MG, the RRM measurement based on SMTC, and the RRM measurement based on CSI-RS is from high to low, the terminal device will skip the RRM measurement on the measurement period 1 and the measurement period 4.

[0220] 2) If the access network device sends the first information indicating skipping RRM measurement on 3 measurement periods at the position shown in FIG. 7, if the first period is the period of the PDB window, the priority of the MG-based RRM measurement, the SMTC-based RRM measurement, and the CSI-RS-based RRM measurement is from low to high, and the terminal device skips the RRM measurement on the 3 measurement periods of measurement period 7, measurement period 8, and measurement period 4.

[0221] It can be understood that, by the technical solution provided in this embodiment, since the terminal device skips the RRM measurement on the N measurement periods in the order of the priority of the RRM measurement types from high to low, the network device can perform data transmission of the XR service on the N measurement periods skipped by the terminal device, so that the reliability of the XR service can be preferentially ensured, and the problem that the remaining time after the measurement time is removed within the delay requirement for the service transmission is not enough to ensure the transmission of the XR service can be reduced. In addition, under the technical solution, since it is specified that the terminal device skips the RRM measurement on the N measurement periods in the order of the priority of the RRM measurement types from high to low, even if there are multiple RRM measurement types of RRM measurement, it is also helpful for the terminal device to determine which N measurement periods of RRM measurement should be skipped.

[0222] As an optional embodiment, the terminal device skips the RRM measurement on the N measurement periods in the order of the priority of the RRM measurement types from high to low, including: the terminal device skips the RRM measurement on the N measurement periods in the order of the priority of the RRM measurement types from high to low, and in the order of the measurement periods from front to back for the measurement periods of the RRM measurement types with the same priority. That is, after receiving the third information, the terminal device determines the RRM measurement on the N measurement periods to be skipped in the order of the priority of the RRM measurement types from high to low, and then in the order of the measurement periods from front to back for the measurement periods of the RRM measurement types with the same priority.

[0223] For example, the order of the measurement periods from front to back for the measurement periods of the RRM measurement types with the same priority includes the order of the start time of the measurement periods from front to back for the measurement periods of the RRM measurement types with the same priority.

[0224] Exemplarily, assuming that data transmission of the XR service arrives at the terminal device at 60 FPS, i.e., the frame arrival period of the XR service is 16.67 ms, the PDB of the XR service is 10 ms, the RRM measurement types performed by the terminal device include the MG-based RRM measurement, the SMTC-based RRM measurement, and the CSI-RS-based RRM measurement, and the time diagram of various RRM measurements performed by the terminal device and data transmission of the XR service in a period is as shown in FIG. 7. In this scenario:

[0225] 1) If the priority of the MG-based RRM measurement is the highest, the priorities of the SMTC-based RRM measurement and the CSI-RS-based RRM measurement are the same and lower than that of the MG-based RRM measurement. At this time, if the access network device indicates skipping RRM measurement in 3 measurement periods as shown in FIG. 7, the terminal device skips RRM measurement in the 3 measurement periods according to the order from high to low of the priority of the RRM measurement type, and the order from front to back of the start time of the measurement period of the RRM measurement type with the same priority. At this time, the terminal device skips RRM measurement in measurement period 1, measurement period 7, and measurement period 4.

[0226] 2) If the priority of the SMTC-based RRM measurement is the highest, the priorities of the MG-based RRM measurement and the CSI-RS-based RRM measurement are the same and lower than that of the SMTC-based RRM measurement. At this time, if the access network device indicates skipping RRM measurement in 3 measurement periods as shown in FIG. 7, the terminal device skips RRM measurement in the 3 measurement periods according to the order from high to low of the priority of the RRM measurement type, and the order from front to back of the start time of the measurement period of the RRM measurement type with the same priority. At this time, the terminal device skips RRM measurement in measurement period 4, measurement period 7, and measurement period 8.

[0227] Optionally, the terminal device skips RRM measurement in N measurement periods according to the order from high to low of the priority of the RRM measurement type, including that the terminal device skips RRM measurement in N measurement periods according to the order from high to low of the priority of the RRM measurement type, the order from front to back of the measurement period with the same priority, the order from long to short of the target time length corresponding to the measurement period with the same priority and the same start time of the RRM measurement type.

[0228] Exemplarily, assuming that the data transmission of the XR service arrives at the terminal device at 60 FPS, i.e., the frame arrival period of the XR service is 16.67 ms, the PDB of the XR service is 10 ms, the RRM measurement types performed by the terminal device include the MG-based RRM measurement, the SMTC-based RRM measurement, and the CSI-RS-based RRM measurement, and the schematic diagram of the time of the various RRM measurements performed by the terminal device and the data transmission of the XR service in a period is as shown in FIG. 8. In this scenario: if the priority of the MG-based RRM measurement and the priority of the CSI-RS-based RRM measurement are the same, the priority of the SMTC-based RRM measurement is the highest, at this time, if the access network device indicates to skip the RRM measurement in the measurement periods of 3 in the position shown in FIG. 8, then the terminal device will skip the RRM measurement in the measurement periods of 4, 7, and 1 in the order of the priority of the RRM measurement type from high to low, the order of the measurement period from front to back for the measurement periods of the RRM measurement types with the same priority, and the order of the duration of the measurement period from long to short for the measurement periods of the RRM measurement types with the same priority and the same starting time.

[0229] As an optional embodiment, the terminal device skips the RRM measurement in N measurement periods in the order of the priority of the RRM measurement type from high to low, including: skipping the RRM measurement in N measurement periods in the order of the priority of the RRM measurement type from high to low, and in the order of the duration of the measurement period from long to short for the measurement periods of the RRM measurement types with the same priority. That is, after receiving the third information, the terminal device takes the order of the priority of the RRM measurement type from high to low as the principle, and then determines the RRM measurement to be skipped in N measurement periods in the order of the duration of the measurement period from long to short for the measurement periods of the RRM measurement types with the same priority.

[0230] Exemplarily, assuming that the data transmission of the XR service arrives at the terminal device at 60 FPS, i.e., the frame arrival period of the XR service is 16.67 ms, the PDB of the XR service is 10 ms, the RRM measurement types performed by the terminal device include the MG-based RRM measurement, the SMTC-based RRM measurement, and the CSI-RS-based RRM measurement, and the schematic diagram of the time of the various RRM measurements performed by the terminal device and the data transmission of the XR service in a period is as shown in FIG. 10. In this scenario:

[0231] 1) If the priority of the MG-based RRM measurement is the highest, the priority of the SMTC-based RRM measurement and the priority of the CSI-RS-based RRM measurement are the same and lower than the priority of the MG-based RRM measurement, at this time, if the access network device indicates to skip the RRM measurement on 2 measurement periods in the position shown in FIG. 10, then the terminal device will skip the RRM measurement on the 2 measurement periods of measurement period 1 and measurement period 4 in the order of the priority of the RRM measurement type from high to low, and the order of the measurement period of the RRM measurement type with the same priority from long to short.

[0232] 2) If the priority of the SMTC-based RRM measurement is the highest, the priority of the MG-based RRM measurement and the priority of the CSI-RS-based RRM measurement are the same and lower than the priority of the SMTC-based RRM measurement, at this time, if the access network device indicates to skip the RRM measurement on 2 measurement periods in the position shown in FIG. 10, then the terminal device will skip the RRM measurement on the 2 measurement periods of measurement period 4 and measurement period 1 in the order of the priority of the RRM measurement type from high to low, and the order of the measurement period of the RRM measurement type with the same priority from long to short.

[0233] Optionally, the terminal device skips the RRM measurement on N measurement periods in the order of the priority of the RRM measurement type from high to low, including: skipping the RRM measurement on N measurement periods in the order of the priority of the RRM measurement type from high to low, and the order of the measurement period of the RRM measurement type with the same priority from long to short, and the order of the measurement period of the RRM measurement type with the same priority and the same duration from front to back. It can be understood that the start time here can be replaced by other times, such as middle time or end time, which will not be described here.

[0234] As an example, assuming that the data transmission of the XR service reaches the terminal device at 60FPS, i.e., the frame arrival period of the XR service is 16.67ms, the PDB of the XR service is 10ms, the RRM measurement types performed by the terminal device include the MG-based RRM measurement, the SMTC-based RRM measurement, and the CSI-RS-based RRM measurement, and in a certain period, the time diagram of various RRM measurements performed by the terminal device and the data transmission of the XR service is shown in FIG. 7. In this scenario:

[0235] 1) If the duration of the measurement period included in the MG-based RRM measurement is 6 ms, the duration of the measurement period included in the SMTC-based RRM measurement and the duration of the measurement period included in the CSI-RS-based RRM measurement are the same and less than 6 ms, the priority of the MG-based RRM measurement is the highest, the priorities of the SMTC-based RRM measurement and the CSI-RS-based RRM measurement are the same and lower than the priority of the MG-based RRM measurement, and the access network device indicates to skip the RRM measurement on 2 measurement periods in the position shown in FIG. 7, then the RRM measurement types are skipped on the measurement period 1 and the measurement period 7 in the order of the priority of the RRM measurement types from high to low, the order of the measurement periods with the same priority of the RRM measurement types from long to short according to the duration of the measurement period, and the order of the measurement periods with the same priority of the RRM measurement types and the same duration from front to back according to the starting time of the measurement period.

[0236] As an optional embodiment, the terminal device skips the RRM measurement on N measurement periods in the order of the priority of the RRM measurement types from high to low, including: skipping the RRM measurement on N measurement periods in the order of the priority of the RRM measurement types from high to low, and in the order of the overlapping duration of the measurement period and the data transmission period from long to short according to the measurement period for the RRM measurement types with the same priority. That is, after receiving the third information, the terminal device determines the RRM measurement to be skipped on N measurement periods in the order of the priority of the RRM measurement types from high to low, and then in the order of the overlapping duration of the measurement period and the data transmission period from long to short according to the measurement period for the RRM measurement types with the same priority.

[0237] Optionally, the terminal device skips the RRM measurement on N measurement periods in the order of the priority of the RRM measurement types from high to low, including: skipping the RRM measurement on N measurement periods in the order of the priority of the RRM measurement types from high to low, in the order of the overlapping duration of the measurement period from long to short according to the measurement period for the RRM measurement types with the same priority, and in the order of the starting time of the measurement period from front to back for the measurement periods with the same priority of the RRM measurement types and the same overlapping duration. Understandably, the starting time here can be replaced by other time, such as the middle time or the end time, which is not described here.

[0238] The above describes how the terminal device skips the RRM measurement on N measurement periods in the order of the priority of the RRM measurement types from high to low.

[0239] Next, the schematic flow chart of another communication method of the present application is introduced in combination with FIG. 12. As shown in FIG. 12, the method includes:

[0240] S1210, the access network device sends fourth information to the terminal device, and the terminal device receives the fourth information. The fourth information indicates to skip RRM measurement on M measurement periods of a first RRM measurement type.

[0241] That is, in this embodiment, the access network device indicates to the terminal device to skip RRM measurement of which RRM measurement type through the fourth information.

[0242] In a possible implementation, the fourth information is 1 bit. When the 1 bit takes different values, the first RRM measurement type indicated is different.

[0243] For example, when the 1 bit takes a value of 1, it indicates to skip RRM measurement on a measurement period based on MG measurement. At this time, the first measurement type can be considered as RRM measurement based on MG. When the 1 bit takes a value of 0, it indicates to skip RRM measurement of all RRM measurement types. At this time, the first measurement type is all RRM measurement types performed by the terminal device. Alternatively, when the 1 bit takes a value of 0, it indicates to the terminal device to skip RRM measurement based on SMTC. At this time, the first measurement type can be considered as RRM measurement based on SMTC.

[0244] In another possible implementation, the fourth information includes multiple bits. When the multiple bits take different values, the first RRM measurement type indicated is different.

[0245] For example, the fourth information is 2 bits. 00 indicates to skip RRM measurement based on MG, 01 indicates to skip RRM measurement based on SMTC, 10 indicates to skip RRM measurement based on CSI-RS, and 11 indicates to perform RRM measurement of all RRM measurement types performed by the terminal device.

[0246] S1220, the terminal device skips RRM measurement on M measurement periods of the first RRM measurement type based on the fourth information.

[0247] In this embodiment, after receiving the fourth information, the terminal device skips RRM measurement on M measurement periods of the first RRM measurement type indicated by the fourth information based on the indication of the fourth information.

[0248] Optionally, in this embodiment, the fourth information further indicates to skip RRM measurement on P measurement periods of a second RRM measurement type. Correspondingly, the terminal device skips RRM measurement on P measurement periods of the second RRM measurement type based on the fourth information.

[0249] By the technical solution, the terminal device is indicated to skip the RRM measurement on the M measurement periods of the first RRM measurement type, so that even if there are multiple RRM measurement types of RRM measurement, the terminal device can definitely determine which N measurement periods of RRM measurement should be skipped. The multiple RRM measurement types are not described. On the other hand, in implementation, the RRM measurement type that has a greater impact on the XR service transmission performance can be determined as the first RRM measurement type here, so it can be considered that the fourth information indicates the terminal device to skip the RRM measurement on the M measurement periods corresponding to the RRM measurement type that has a greater impact on the XR service transmission performance, thereby ensuring the performance of the RRM measurement that has a smaller impact on the XR service transmission, and achieving a compromise effect of the XR service and the terminal device performing RRM measurement.

[0275] In the downlink or sidelink direction, the radio frequency processing system 1020 receives radio frequency signals through the antenna 1010, and sends the signals after radio frequency processing to the processor system 1030 for further processing. In the uplink or sidelink direction, the processor system 1030 performs signal processing on the information at the terminal side, and sends the signal to the radio frequency processing system 1020, which performs radio frequency processing on the signal and transmits it through the antenna 1010.
