Description

Communication method, communication apparatus, computer-readable storage medium, and computer program product

[0001] This application claims priority to the Chinese patent application No. 202411365423.3, filed on September 27, 2024, with the State Intellectual Property Office of China, and entitled "Communication method, communication apparatus, computer-readable storage medium, and computer program product", the entire content of which is incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to the field of communication, in particular to a communication method, a communication apparatus, a computer-readable storage medium, and a computer program product. BACKGROUND

[0003] In recent years, with the continuous development of the fifth generation (5G) communication system, the data transmission delay is continuously reduced, and the transmission capacity is increasingly large. The 5G communication system gradually penetrates into some multimedia services with strong real-time performance and large data capacity requirements, such as real-time video transmission, cloud gaming, and extended reality (XR), etc. Among them, XR includes virtual reality (VR) and augmented reality (AR).

[0004] With the rapid improvement of communication transmission rate, real-time video transmission service has gradually become one of the core services in the current network. With the continuous progress and improvement of extended reality technology, the related industry has also developed vigorously. Today, VR technology, as a kind of XR, has entered various fields closely related to people's production and life, such as education, entertainment, military, medical treatment, environmental protection, transportation, and public health. Compared with traditional video services, VR has the advantages of multi-view and strong interactivity, providing users with a completely new visual experience. VR combines computer graphics, multimedia and other technologies to simulate the functions of human sensory organs such as vision, hearing and touch, making people feel as if they are in a virtual world, and can communicate in real time through language and gestures, enhancing the sense of immersion. Through VR technology, people can experience the wonderful experience of entering a virtual world while feeling the realism of the real world. AR is to use computer technology to superimpose virtual information on the real world, which is displayed through mobile phones, tablets, glasses and other devices and perceived by people, so as to realize the integration of reality and virtuality, enrich the real world. In short, it is to give real objects more information, enhance the three-dimensional effect, and strengthen the visual effect and interactive experience.

[0005] Real-time video transmission services, XR services, and the like have high delay requirements. How to reduce the delay requirements of real-time video transmission services, XR services, and the like is a problem to be solved at present. SUMMARY

[0006] In a first aspect, an embodiment of 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 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), for example. In the method, the terminal receives downlink control information, which is carried on a physical downlink control channel (PDCCH). The downlink control information is used to schedule data transmission on a first component carrier (CC). First indication information in the downlink control information is used to indicate skipping of first radio resource management (RRM) measurement on the first CC. Based on the downlink control information, the first RRM measurement on the first CC is skipped. The time period in which the first RRM measurement is located is the first time period for RRM measurement after the last symbol of the PDCCH is offset by a first time offset. The terminal skipping the first RRM measurement on the first CC can be understood as the terminal not performing the first RRM measurement on the first CC. It can also be understood that the terminal regards the time period in which the first RRM measurement is located as a time period in which data transmission on the first CC is available. It can also be other expressions with the same or similar meanings.

[0007] With the above method, the terminal skips the first RRM measurement on the first CC based on the downlink control information. Thus, the RRM measurement of the terminal on the first CC does not cause scheduling restrictions on data transmission of the terminal on the first CC, and the delay of data transmission can be reduced.

[0008] In a second aspect, an embodiment of the present application provides another communication method, which can be applied to a terminal side, for example, a terminal or a communication module in the terminal, or a circuit or chip (for example, a modem chip, also known as a baseband chip, or a SoC chip or SIP chip containing a modem core) responsible for communication functions in the terminal. For example, in the method, the terminal receives downlink control information, the downlink control information is carried in a PDCCH, the downlink control information is used to schedule data transmission on a first CC, and first indication information in the downlink control information is used to indicate skipping of a first RRM measurement on the first CC. Based on the downlink control information, the terminal skips the first RRM measurement on the first CC, and the time period for the first RRM measurement is the first time period for RRM measurement after the last symbol of the PDCCH is offset by a first time offset. In addition, the terminal also skips a second RRM measurement on a third CC if at least a first condition is met.

[0009] By using the above method, the terminal skips the first RRM measurement on the first CC based on the downlink control information, and also skips the second RRM measurement on the third CC if at least the first condition is met. Thus, the RRM measurement of the terminal on each CC does not cause scheduling restrictions on data transmission of the terminal on the first CC, and the time delay of data transmission can be reduced. In addition, the terminal also skips the second RRM measurement on the third CC based on the downlink control information if at least the first condition is met, and does not have to indicate skipping of the second RRM measurement on the third CC through other DCI, which can save signaling overhead.

[0010] In a possible design, the first condition includes any of the following: a time period for the second RRM measurement overlaps with a time period for the first RRM measurement in the time domain, and a start time of the time period for the second RRM measurement and an end time of the time period for the first RRM measurement are separated by less than or equal to a first threshold. In the case where the first condition is met, the second RRM measurement on the third CC is also skipped, which can reduce the impact of the RRM measurement on the third CC on data transmission on the first CC.

[0011] In a third aspect, an embodiment of the present application provides another communication method, which can be applied to a terminal side, for example, a terminal or a communication module in the terminal, or a circuit or chip (for example, a modem chip, also known as a baseband chip, or a SoC chip or SIP chip containing a modem core) responsible for communication functions in the terminal. For example, in the method, the terminal receives downlink control information, the downlink control information is carried on a PDCCH, the downlink control information is used to schedule data transmission on a first CC, and first indication information in the downlink control information is used to indicate that skipping a first RRM measurement on the first CC is allowed. Based on the downlink control information, if a third condition is met, the first RRM measurement on the first CC is skipped; or if the third condition is not met, the first RRM measurement on the first CC is performed.

[0012] With the above method, based on the downlink control information, if the third condition is met, the first RRM measurement on the first CC is skipped, thereby reducing the scheduling restriction of the RRM measurement on the first CC of the terminal on the data transmission on the first CC of the terminal; or if the third condition is not met, the first RRM measurement on the first CC is performed, thereby reducing the influence of the RRM measurement skipping on the measurement performance.

[0013] In a possible design, the third condition includes any of the following: the time period required for the data transmission on the first CC scheduled by the downlink control information to occupy overlaps in time domain with the time period where the first RRM measurement is located, that is, the time domain resource allocated by the downlink control information for scheduling the data transmission on the first CC includes the time period where the first RRM measurement is located or a part of the time period where the first RRM measurement is located, and the interval between the start time of the time period where the first RRM measurement is located and the end time of the time period required for the data transmission on the first CC scheduled by the downlink control information to occupy is less than or equal to a second threshold. If the third condition is met, the first RRM measurement on the first CC is skipped, which can reduce the scheduling restriction of the RRM measurement on the first CC of the terminal on the data transmission on the first CC of the terminal, thereby reducing the time delay of the data transmission. If the third condition is not met, the first RRM measurement on the first CC is performed, which can reduce the influence of the RRM measurement skipping on the measurement performance.

[0014] In a fourth aspect, another method for communication 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 (e.g., a modem chip, also referred to as a baseband chip, or a SoC chip or a SIP chip including a modem core) responsible for communication functions in the terminal. In an example in which the method is applied to a terminal, in the method, the terminal receives downlink control information, the downlink control information is carried in a PDCCH, the downlink control information is used to schedule data transmission on a first CC, and first indication information in the downlink control information is used to indicate that skipping of a first RRM measurement on the first CC is allowed. Based on the downlink control information, in a case where a third condition is met, the first RRM measurement on the first CC is skipped, and in a case where at least a first condition is met, a second RRM measurement on a third CC is also skipped; or in a case where the third condition is not met, the first RRM measurement on the first CC is performed.

[0015] With the above method, in a case where the third condition is met, the first RRM measurement on the first CC is skipped, and in a case where at least the first condition is met, the second RRM measurement on the third CC is also skipped, thereby reducing the scheduling restriction of the RRM measurement on the first CC of the terminal on the data transmission on the first CC of the terminal and saving signaling overhead; or in a case where the third condition is not met, the first RRM measurement on the first CC is performed, thereby reducing the influence of the RRM measurement skipping on the measurement performance.

[0016] In a possible design, the third condition includes any of the following: a time period required to be occupied by the data transmission on the first CC scheduled by the downlink control information overlaps in time domain with a time period in which the first RRM measurement is located, i.e., time domain resources allocated by the downlink control information for scheduling the data transmission on the first CC include the time period in which the first RRM measurement is located or a part of the time period in which the first RRM measurement is located, and a time interval between a start time of the time period in which the first RRM measurement is located and an end time of the time period required to be occupied by the data transmission on the first CC scheduled by the downlink control information is less than or equal to a second threshold. In a case where the third condition is met, the first RRM measurement on the first CC is skipped, which can reduce the scheduling restriction of the RRM measurement on the first CC of the terminal on the data transmission on the first CC of the terminal, thereby reducing the latency of the data transmission. In a case where the third condition is not met, the first RRM measurement on the first CC is performed, which can reduce the influence of the RRM measurement skipping on the measurement performance.

[0017] In a possible design, the first condition includes any of the following: a time period in which the second RRM measurement is located overlaps with a time period in which the first RRM measurement is located in a time domain, or a start time of the time period in which the second RRM measurement is located is separated from an end time of the time period in which the first RRM measurement is located by less than or equal to a first threshold; in a case where the first condition is met, the second RRM measurement on the third CC is also skipped, and the impact of the RRM measurement on the third CC on the data transmission on the first CC can be reduced.

[0018] In a fifth aspect, an embodiment of the present application provides another communication method, which can be applied to a terminal side, for example, a terminal or a communication module in the terminal, or a circuit or chip (for example, a modem chip, also known as a baseband chip, or a SoC chip or SIP chip containing a modem core) responsible for a communication function in the terminal. Taking the case where the method is applied to the terminal as an example, in the method, the terminal receives downlink control information, the downlink control information is carried in a PDCCH, the downlink control information is used to schedule data transmission on multiple cells, and second indication information in the downlink control information is used to indicate skipping of fourth RRM measurement on the multiple cells; based on the downlink control information, the fourth RRM measurement on the multiple cells is skipped, and a time period in which the fourth RRM measurement on one of the multiple cells is located is a periodic time period for RRM measurement of the terminal on the cell, and a first time period for RRM measurement after a last symbol of the PDCCH is offset by a second time offset.

[0019] In the embodiment of the present application, the terminal skips the fourth RRM measurement on the multiple cells based on the downlink control information, so that the RRM measurement of the terminal on the multiple cells does not cause scheduling restriction on data transmission of the terminal on the multiple cells, and the time delay of the data transmission can be reduced.

[0020] In a sixth aspect, an embodiment of the present application provides another communication method, which can be applied to a terminal side, for example, a terminal or a communication module in the terminal, or a circuit or chip (for example, a modem chip, also known as a baseband chip, or a SoC chip or SIP chip containing a modem core) responsible for a communication function in the terminal. Taking the case where the method is applied to the terminal as an example, in the method, the terminal receives downlink control information, the downlink control information is carried in a PDCCH, the downlink control information is used to schedule data transmission on multiple cells, and second indication information in the downlink control information is used to indicate skipping of fourth RRM measurement on the multiple cells; based on the downlink control information, the fourth RRM measurement on one or more first cells is skipped, the fourth RRM measurement on the first cells meets a fourth condition; or the fourth RRM measurement on one or more second cells is performed, and the fourth RRM measurement on the second cells does not meet the fourth condition.

[0021] In the embodiments of the present application, the terminal skips the fourth RRM measurement on one or more first cells based on the downlink control information, the fourth RRM measurement on the first cell meets the fourth condition, thereby reducing the scheduling restriction of the RRM measurement of the terminal on the cell on the data transmission of the terminal on the cell; or, performing the fourth RRM measurement on one or more second cells, the fourth RRM measurement on the second cell does not meet the fourth condition, thereby reducing the influence of the RRM measurement skipping on the measurement performance.

[0022] In a possible design of any of the first aspect to the sixth aspect, the method further includes: the terminal sending first capability information, the first capability information being used to report the capability of skipping the RRM measurement in a terminal granularity; and receiving first configuration information, the first configuration information containing the RRM measurement configuration configured in a terminal granularity, thereby the terminal can skip the RRM measurement in a terminal granularity. The terminal skips the RRM measurement in a terminal granularity, and does not have to indicate the skipping of the RRM measurement on different CCs by different DCIs, which can save the signaling overhead of the DCI.

[0023] In a possible design of any of the first aspect to the sixth aspect, the method further includes: the terminal sending second capability information, the second capability information being used to report the capability of skipping the RRM measurement in a frequency granularity; and receiving second configuration information, the second configuration information containing the RRM measurement configuration configured in a frequency granularity, thereby the terminal can skip the RRM measurement in a frequency granularity. The terminal skips the RRM measurement in a frequency granularity, which can reduce the influence of the RRM measurement skipping on the measurement performance.

[0024] In the seventh aspect, the embodiments of the present application provide another communication method, which can be applied to the network side, for example, an access network device of the network side, a module (for example, a circuit, a chip or a chip system, etc.) in the access network device, or a logic node, a logic module or software capable of realizing all or part of the functions of the access network device. Taking the case that the method is applied to the access network device, in the method, the access network device generates downlink control information, the downlink control information is carried in a PDCCH, the downlink control information is used to schedule the data transmission on a first CC, first indication information in the downlink control information is used to indicate skipping a first RRM measurement on the first CC, a time period where the first RRM measurement is located is a first time period for RRM measurement after a last symbol of the PDCCH is offset backward by a first time offset; and the access network device sends the downlink control information.

[0025] By using the above method, the access network device sends the downlink control information, so that the terminal skips the first RRM measurement on the first CC based on the downlink control information, thereby the RRM measurement of the terminal on the first CC will not cause the scheduling restriction of the data transmission of the terminal on the first CC, and the time delay of the data transmission can be reduced.

[0026] In one possible design, the PDCCH is carried on a second CC, which is different from the first CC.

[0029] In one possible design of any of the first aspect to the seventh aspect, the first time offset is related to a sub-carrier spacing (SCS) of the first CC, so that the first time offset can be reasonably determined, and in turn, the first RRM measurement on the first CC is skipped to reduce latency of data transmission.

[0030] In one possible design of any of the first aspect to the seventh aspect, the PDCCH is carried on a second CC, and the first time offset is a larger one of a time offset corresponding to an SCS of the first CC and a time offset corresponding to an SCS of the second CC, so that the first time offset can be reasonably determined, and in turn, the first RRM measurement on the first CC is skipped to reduce latency of data transmission.

[0031] In one possible design of any of the first aspect to the seventh aspect, RRM measurement configurations of the first CC and the second CC are uniformly configured, so that the terminal can skip RRM measurement on the first CC and the second CC at the same time, and signaling overhead is saved.

[0072] The following introduces the system related to the embodiments of the present application.

[0073] Figure 1 shows a possible, non-limiting, schematic diagram of a system. As shown in Figure 1, the communication system 10 includes a radio access network (RAN) 100 and a core network (CN) 200. Optionally, the communication system 10 also includes the Internet 300. The RAN 100 includes at least one RAN node (e.g., 110a and 110b in Figure 1, collectively referred to as 110) and at least one terminal (e.g., 120a-120j in Figure 1, collectively referred to as 120). Other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 1), can also be included in the RAN 100. The terminals 120 are wirelessly connected to the RAN nodes 110. The RAN nodes 110 are connected to the core network 200 by wireline or wireless means.

The RAN 100 can also be an open RAN (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 integrates two or more of the above systems.

[0075] The RAN nodes 110, which can also be referred to as access network devices, RAN entities, or access nodes, form part of the communication system and help terminals to access the wireless access. The RAN nodes 110 in the communication system 10 can be the same type of nodes or different types of nodes. In some scenarios, the roles of the RAN nodes 110 and the terminals 120 are relative, e.g., the network element 120i in Figure 1 can be a helicopter or a drone, which can be configured as a mobile base station. For a terminal 120j that accesses 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 nodes 110 and the terminals 120 are sometimes referred to as communication apparatuses, e.g., the network elements 110a and 110b in Figure 1 can be understood as communication apparatuses with base station functions, and the network elements 120a-120j can be understood as communication apparatuses with terminal functions.

[0076] 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.

[0077] 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).

[0078] 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.

[0079] The access network device can be any kind of device with wireless transceiver function. It includes but is not limited to: the traditional macro base station (eNB) in universal mobile communication system (UMTS) / long term evolution (LTE), which can be a micro base station (eNB) in a heterogeneous network (HetNet) scenario, a baseband processing unit (BBU) and a remote radio unit (RRU) in a distributed base station scenario, a baseband pool (BBU pool) and a radio unit RRU in a cloud radio access network (CRAN) scenario, a gNB in a future wireless communication system, a 3GPP subsequent evolution base station, an access node in a WiFi system, a wireless relay node, a wireless backhaul node, etc. The base station can be: a macro base station, a micro base station, a pico base station, a small station, a relay station, or a balloon station, etc. The access network device can also be a server, a wearable device, or a vehicle-mounted device, etc. The embodiments of the present application do not limit the device form of the access network device. The communication module, circuit or chip for performing the corresponding communication function is usually arranged in the access network device. The access network device is also configured with program instructions for performing the corresponding communication function.

[0080] Terminal, which can be a device or module with corresponding communication functions and can access the above-mentioned communication system. The terminal can also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. The terminal can be widely used in various scenarios, such as device-to-device (D2D), 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 grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal can be a mobile phone, tablet computer, computer with wireless transceiver function, wearable device, vehicle, unmanned aerial vehicle, helicopter, airplane, ship, robot, mechanical arm, smart home device, transport vehicle with wireless communication function, communication module, etc. The terminal can also be a vehicle-mounted communication module or other embedded communication module, mobile phone, tablet computer, computer with wireless transceiver function, VR terminal device, AR terminal device, wireless terminal in industrial control, haptic terminal device, vehicle-mounted terminal device, wireless terminal in unmanned driving, wireless terminal in remote medical treatment, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, wearable terminal device, etc. The embodiments of the present application do not limit the device form of the terminal. The terminal is usually provided with a communication module, circuit or chip for executing corresponding communication functions. The terminal is also configured with program instructions for executing corresponding communication functions.

[0081] The following introduces the terms or technologies related to the embodiments of the present application.

[0082] 1. Extended reality (XR) service and video transmission service

[0083] With the rapid increase of communication transmission rate, real-time video transmission service has gradually become one of the core services in the current network. With the continuous progress and improvement of extended reality technology, the related industry has also developed vigorously. XR includes virtual reality (VR) and augmented reality (AR). For XR service (or XR transmission service) and video transmission service, the service model is usually periodic according to frame rate. FIG. 2 is a schematic diagram of periodic arrival of a video frame provided by the present application. As shown in FIG. 2, a video with a frame rate of 60 frames per second (FPS) arrives at a video frame (or picture frame) every 16.67 milliseconds in an ideal case.

[0084] XR service has strict delay requirements. For example, a typical downlink service of 30 Mbps @ 60 FPS has a packet delay budget (PDB) of 10 ms. FIG. 3 is a schematic diagram of the architecture of a communication network provided by the present application. As shown in FIG. 3, the end-to-end downlink transmission path of the XR service is server- fixed network / core network-radio access network (RAN)-user equipment (UE). Referring to FIG. 3, taking the downlink transmission as an example, the video frame of the XR service needs to be transmitted from the server to the UE within a certain time, and the end-to-end delay (from the server to the UE) of the XR service is 70 ms (an example), then the PDB of the RAN sending to the UE receiving is generally 10 ms. In the present application, UE and user can be replaced with each other, terminal and UE can be replaced with each other, terminal and user can be replaced with each other.

[0085] Cloud VR and cloud AR are the introduction of cloud computing and cloud rendering concepts and technologies into VR / AR service applications. Cloud VR and cloud AR transmit the encoded and compressed display output and sound output from the cloud to the UE through a high-speed and stable network, realize cloud computing and cloud rendering of VR / AR service content, and realize the lightweight and mobility requirements of VR / AR terminal devices. FIG. 4 is a schematic diagram of the architecture of a communication network provided by the present application. Referring to FIG. 4, UE1 and UE2 are connected to the network through a base station or an access point to obtain VR / AR service from the cloud. UE1 and UE2 are VR / AR terminal devices.

[0086] Cloud XR service (i.e., cloud VR service and cloud AR service) has strict latency requirement on network, the motion to photons (MTP) latency should be less than 20 ms, so as to provide partial immersive experience. In some possible solutions, cloud XR service is implemented by using asynchronous rendering technology, the end-to-end interaction latency can be relaxed to 70 ms, excluding the encoding and rendering latency on the server side and the decoding processing latency on the terminal, only 20 ms is left for network transmission, of which 10 ms for uplink transmission and 10 ms for downlink transmission. In recent years, with the evolution of XR service, including the maturity of haptic internet technology, the latency requirement on network is further strict, for example, in a remote control system, in order to improve the fidelity of haptics and remote operation, the sampling rate of haptic information should be no less than 1 kHz, and the transmission latency requirement of a sample is 5 ms, which brings great challenge to 5G system or future communication system.

[0087] 2. Intra-frequency measurement, inter-frequency measurement and measurement gap (MG)

[0088] In mobile cellular network, when a UE moves from one cell (e.g., a cell covered by base station #1) to another cell (e.g., a cell covered by base station #2), the UE needs to perform handover between cells. Before handover, the UE needs to measure the signal of the neighboring cell (also can be called neighbor cell or adjacent cell or neighboring cell) to determine when to perform handover. The UE needs to measure the signal of the neighboring cell is divided into intra-frequency measurement and inter-frequency measurement. Intra-frequency measurement refers to that the cell where the UE currently locates and the target cell to be measured are on the same carrier frequency point (center frequency point). In intra-frequency measurement, the UE can measure by using the reference signal inserted in data transmission, without affecting data transmission and reception. Inter-frequency measurement refers to that the cell where the UE currently locates and the target cell to be measured are not on the same carrier frequency point. In inter-frequency measurement, the UE can use measurement gap (MG) to measure the signal of the target cell. The measurement gap can also be called measurement interval. The duration that the UE suspends communication with the serving cell to measure the inter-frequency neighbor or other RAT neighbor is called MG. The UE uses MG to measure the inter-frequency measurement in the following way: a part of time is reserved, in the reserved time, the UE will not perform service data transmission in its serving cell, but will adjust the receiver to the frequency point of the target cell to perform inter-frequency measurement of the target cell. The reserved part of time is the MG time, and after the MG time ends, the receiver is adjusted to the current cell, i.e., the serving cell of the UE.

[0089] The configuration parameters of the MG are exemplarily described below. It should be noted that the specific values of the configuration parameters of the MG below are only examples, and the specific values of the configuration parameters of the MG are not limited in the present application.

[0090] Measurement gap repetition period (MGRP): The MGRP is used to determine the period of the MG, or in other words, the MGRP specifies the period of the MG. The MGRP can be 20 ms, 40 ms, 80 ms, 160 ms, etc. Exemplarily, as shown in FIG. 5, the MG repeats every 4 frames within 40 ms, and the MG is 40 ms. FIG. 5 is a schematic diagram of a MG configuration provided by an embodiment of the present application. As shown in FIG. 5, the MGRP is 40 ms, and the black-filled rectangular box represents the MG.

[0091] Measurement gap length (MGL): The MGL is used to determine the duration of the MG, or in other words, the MGRP specifies the duration of the MG. The MGL can be 1.5 ms, 3 ms, 3.5 ms, 4 ms, 5.5 ms, 6 ms, etc. Exemplarily, as shown in FIG. 5, the duration of the MG is 4 ms. Exemplarily, for services including positioning measurement, the MGL above can be 10 ms or 20 ms.

[0092] Gap offset: The gap offset is used to determine the starting position of the MG, and the gap offset can be configured by a high-level parameter. The value range of the gap offset is generally 0≤gapoffset≤MGRP-1. For example, if the MGRP is 20 ms, the range of the gap offset is 0≤gapoffset≤19. The gap offset can have about 160 values, but not all values are suitable for all MGRPs. Exemplarily, as shown in FIG. 5, the gap offset can be 24 ms. Exemplarily, the subframe number (SFN), the subframe position, and the gap offset of the starting position of the MG satisfy the following formulas: SFN mod T=FLOOR(gapOffset / 10) (1); subframe=gapOffset mod 10 (2);

[0093] Where T = MGRP / 10. FLOOR() is used to round a floating-point number down to the nearest integer less than or equal to the floating-point number. Mod is an operator that returns the remainder of two numbers. For example, A mod B represents the remainder of A divided by B. The SFN and subframe position of the starting position of the MG can be calculated by the above formulas (1)-(3). For example, as shown in FIG. 5, the SFN of the starting position of the MG is 22, and the first MG is subframe #4, subframe #5, subframe #6, and subframe #7 in the SFN 22. The 10 subframes in the radio frame are in time order subframe #0, subframe #1, subframe #2, …, subframe #9.

[0094] By predefining some measurement gap patterns (MG patterns), the UE can inform the access network device (such as a base station) of the supported MG patterns (supportedMGpattern) through UE capability reporting information. The MG pattern (MG pattern) can include the configuration parameters of the above-mentioned MG, and common MG patterns are shown in Table 1. The MG pattern can be written as gap pattern.

[0095] Table 1

[0096] Table 1 shows some examples of common MG patterns. Table 1 can contain more MG patterns, which are not described in detail here.

[0097] The UE can inform the access network device of the MG patterns supported by itself according to its own capabilities. Among them, the above-mentioned MGpattern0 and MGpattern1 are mandatory supported by the UE, and other MG patterns are optionally supported by the capabilities of the UE.

[0098] In some schemes, the UE will not transmit any other signals or data in the MG, except for some important signals (such as access procedure related signals), i.e., the MG has higher priority compared to data transmission and reception.

[0099] A UE can be configured with multiple MGs. The access network device can configure a priority for each MG, for example, represented by the high-level parameter gapPriority-r17. Each MG is configured separately, so there is a possibility that two MGs will conflict in the time domain, i.e., the duration of the two MGs overlaps in the time domain. At this time, the UE can select the MG with higher priority to perform measurement.

[0100] 3. Synchronization signal block (SSB) based measurement timing configuration (SMTC)

[0101] In a new radio (NR) or 5th generation (5G) system, cell switching of a UE is implemented based on SSB measurement. In the NR system, a synchronization signal block (SSB) is generally transmitted together with a main information block (MIB) on a physical broadcast channel (PBCH) to form an SS / PBCH block. The SSB described in the following embodiments of the present application can also refer to the SS / PBCH block. The synchronization signal (SS) can include a primary synchronization signal (PSS) and a secondary synchronization signal (SSS).

[0102] The size of the SSB is generally fixed, for example, occupying 4 consecutive symbols in the time domain and 20 resource blocks (RBs) in the frequency domain. The cell transmits the SSB in a periodic scanning manner, and all SSBs of the cell are transmitted in each scanning round. The SSB scanning period of the cell can be configured (the default is 20 ms), and each scanning round can be completed within a half frame (5 ms), and the time domain position of the SSB (the number of SSBs and the SSB symbol position) is related to the frequency of the SSB and the sub-carrier spacing (SCS).

[0103] In order for the UE to obtain the most accurate SSB measurement result, it is necessary to measure all SSBs of the cell as much as possible. At the same time, SSBs are not transmitted at all time sequences within one scanning period, and if the UE searches and measures SSBs at all time sequences, it will cause a great waste of power. In order to effectively indicate the time window for the UE to measure the SSB and reduce unnecessary power consumption of the UE for measurement, the NR introduces the concept of SMTC. The SMTC is a time window configured by the next generation node B (gNodeB) access network device (such as a gNodeB) for the UE to measure the SSB, and the UE only needs to measure the SSB within the SMTC window, and does not need to measure the SSB outside the window.

[0104] SMTC represents the timing configuration (or SMTC configuration) issued by the gNodeB to the UE when the UE performs SSB-based measurement on a certain cell, including SMTC period, SMTC offset, and SMTC duration. The SMTC configuration can be a frequency point level configuration, including SMTC1 configuration and SMTC2 configuration. The SMTC2 configuration is an optional configuration.

[0105] In a possible design, the SMTC period is greater than or equal to the SSB scanning period of the to-be-measured cell, the SMTC offset determines the starting offset of the SMTC, that is, at what time the measurement is started after the start of the SMTC period; and the SMTC duration is greater than or equal to the effective scanning time in each round of SSB scanning period of the to-be-measured cell. Exemplarily, the starting frame number of the SMTC and the starting subframe number of the SMTC satisfy the following formulas: SFN mod T = FLOOR(offset / 10) (3); subframe = offset mod 10 (4).

[0106] wherein T = periodicity / 10, periodicity represents the SMTC period, SFN is the starting frame number of the SMTC, and subframe is the starting subframe number of the SMTC.

[0107] SMTC1 configuration: The configuration information element corresponding to SMTC1 is SSB-MTC, which includes two sub-information elements, periodicityAndOffset and duration.

[0108] periodicityAndOffset: represents the SMTC period (periodicity, representing the repetition period of the measurement action) and the SMTC offset (offset, representing the starting subframe of the measurement action in the period).

[0109] duration: represents the SMTC duration (representing the duration of the measurement action after the start of the measurement action).

[0110] The SMTC period can be 5 ms, 10 ms, 20 ms, 40 ms, 80 ms, 160 ms, etc. The SMTC offset is valued in 1 ms granularity between 0 and SMTC period minus 1 ms. In other words, 0 ≤ SMTC offset ≤ (SMTC period - 1). The granularity of SMTC duration is also 1 ms, and the length can be 1 ms, 2 ms, 3 ms, 4 ms, 5 ms. For example, when the SMTC period is 5 ms, the SMTC offset can be valued at 0 ms, 1 ms, 2 ms, 3 ms, or 4 ms, and the SMTC duration can be valued at 1 ms, 2 ms, 3 ms, 4 ms, or 5 ms.

[0111] An example of SMTC1 configuration is as follows:

[0112] In the above example of SMTC1 configuration, the UE can select any of the following combinations of SMTC period and SMTC offset: the SMTC period is 5 ms, and the SMTC offset is valued in the range [0, 4] ms; the SMTC period is 10 ms, and the SMTC offset is valued in the range [0, 9] ms; the SMTC period is 20 ms, and the SMTC offset is valued in the range [0, 19] ms; the SMTC period is 4 ms, and the SMTC offset is valued in the range [0, 39] ms; the SMTC period is 80 ms, and the SMTC offset is valued in the range [0, 79] ms; the SMTC period is 160 ms, and the SMTC offset is valued in the range [0, 159] ms. The duration in the SMTC1 configuration can be any of 1 ms, 2 ms, 3 ms, 4 ms, 5 ms.

[0113] SMTC2 configuration (optional): The configuration information element corresponding to SMTC2 is SSB-MTC2. SMTC2 is used to flexibly configure differentiated SMTC periods for specified neighboring cells.

[0114] 4. Cross-carrier scheduling

[0115] Cross-carrier scheduling means that a physical downlink control channel (PDCCH) on one component carrier (CC) is allowed to schedule data transmission on another CC. A component carrier can also be referred to as a carrier component (CC). For convenience of description, in the embodiments of the present application, a component carrier or a carrier is uniformly referred to. For example, cross-carrier scheduling means that a PDCCH on one cell is allowed to schedule radio resources on another cell for uplink or downlink transmission. FIG. 6 is a schematic diagram of a cross-carrier scheduling scenario provided by an embodiment of the present application. In the cross-carrier scheduling scenario shown in FIG. 6, a macro cell and a small cell share two downlink CCs, i.e., CC1 and CC2. The two CCs of the small cell operate at low transmission power, the CC1 of the macro cell operates at high transmission power, and the CC2 of the macro cell operates at low transmission power. Transmission of the macro cell on the CC1 has great interference on transmission of the small cell on the CC1. Therefore, on the small cell, it is beneficial to use a PDCCH on the CC2 to cross-carrier schedule data transmission on the CC1. FIG. 6 shows an example in which the macro cell uses a PDCCH on the CC1 to cross-carrier schedule data transmission carried by a physical downlink shared channel (PDSCH) on the CC2, and an example in which the small cell uses a PDCCH on the CC2 to cross-carrier schedule data transmission carried by a PDSCH on the CC1.

[0116] Currently, the DCI formats supporting cross-carrier scheduling are DCI format 0_1 / 1_1 and DCI format 0_2 / 1_2. DCI format 0_1 is used for the scheduling of one or more PUSCH within a serving cell, or for indicating configured grant downlink feedback information (CG-DFI) to a UE. DCI format 1_1 is used for the scheduling of PDSCH within a cell. DCI format 0_2 is used for the scheduling of PUSCH within a serving cell. DCI format 1_2 is used for the scheduling of PDSCH within a cell. Different formats of DCI contain different contents of fields. Take DCI format 0_1 as an example, there is a carrier indicator field in the bit field of DCI, which indicates which carrier the DCI is for when the UE uses carrier aggregation and cross-carrier scheduling. The carrier indicator field allows the UE to know which component carrier the DCI is for that it monitors. The carrier indicator field is optional in DCI, and only appears when the UE is configured with multiple carriers and the network needs to specify explicitly which carrier the DCI is for.

[0117] When DCI format 0_1 is carried by PDCCH on the primary cell and the UE is configured for scheduling on the primary cell from an SCell, the carrier indicator field is reserved, with the same number of bits as that in this format carried by PDCCH on the SCell for scheduling on the primary cell.

[0118] 5. One DCI schedules multiple cells

[0119] Some DCI formats support the feature of one DCI scheduling data of multiple cells, and the DCI formats supporting this feature are DCI format 0_3 / 1_3. DCI format 0_3 is used for the scheduling of one PUSCH in one cell, or multiple PUSCHs in multiple cells with one PUSCH per cell. The scheduled cells indicator field in DCI format 0_3 / 1_3 is used to indicate in a carrier aggregation (CA) scenario which cells the UE should schedule uplink transmission on. The scheduled cells indicator field allows the base station (for example, eNodeB) to specify a group of cells for the UE, which are used for uplink transmission together, thereby improving the reliability and efficiency of uplink transmission. The specific length and value of the scheduled cells indicator field are determined by the network side configuration, and will be pre-configured in the radio resource control (RRC) signaling. The introduction of the scheduled cells indicator field is to support more flexible uplink scheduling, especially in the scenario of multi-cell cooperative transmission.

[0120] As described in the background section, real-time video transmission services, XR services, etc. have the characteristics of high delay requirements. How to improve the delay performance of real-time video transmission services, XR services, etc. is a problem to be solved at present. The present application provides a technical solution that can reduce the delay of real-time video transmission services, XR services, etc. In the following, the present application takes XR services as an example to introduce the technical solution of the present application in detail. It should also be understood that all services applicable to the technical solution of the present application are included in the protection scope of the present application.

[0121] The applicant finds that one of the reasons for the long delay of XR services in the existing solutions is that the XR service data transmission of the UE conflicts with the radio resource management (RRM) measurement behavior of the UE. In XR services, the arrival period of XR service data is non-integer, for example, 30 frames per second (FPS), 60 FPS, and 90 FPS XR video, and the frame arrival period is 1 / 30 s, 1 / 60 s (i.e., 16.67 ms), and 1 / 90 s, respectively. The RRM measurement period (such as MGRP or SMTC period) is an integer, for example, 5 ms, 10 ms, 20 ms, 40 ms, 80 ms, and 160 ms. It can be seen that the RRM measurement period cannot match the arrival period of XR service data, that is, the time period for the UE to transmit XR service data overlaps with the time period for the UE to perform RRM measurement, as shown in FIG. 7. The priority of RRM measurement is higher than that of XR service data transmission. When the time period for the UE to transmit XR service data overlaps with the time period for the UE to perform RRM measurement, the UE performs RRM measurement first, that is, there is a scheduling restriction. FIG. 7 is a schematic diagram of the arrival period of XR service data and MG conflict provided by an embodiment of the present application. As shown in FIG. 7, the UE transmits 60 FPS XR video frames, the arrival period of XR service data is 16.67 ms, PDB = 10 ms, and MGRP is 40 ms, that is, the UE uses pattern 0 in Table 1. The transmission time period of two XR video frames overlaps with the MG time, and the black rectangular box represents the overlapping part of the transmission time period of the XR video frame and the MG time, that is, the time period without data transmission in the transmission time period of the XR video frame.

[0122] The scheduling restriction caused by RRM measurement has a greater impact on services with high delay requirements, such as XR services and real-time video services. Therefore, the present application provides a technical solution that can reduce the delay of real-time video transmission services, XR services, and other services. The technical solution of the present application is applicable to the scenario where the access network device sends DCI to schedule uplink data transmission, and is also applicable to the cross-carrier scheduling scenario and the scenario where one DCI schedules multiple cells.

[0123] The communication method and device provided by the present application are further described below with reference to the accompanying drawings. It can be understood that the access network device and the terminal are taken as an example to illustrate 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 logic node, a logic module or software capable of realizing all or part of the function of the access network device; the method executed by the terminal in the present application can also be implemented by a communication module in the terminal 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.

[0124] The method provided by the embodiment of the present application is described below.

[0125] FIG. 8 is a flowchart of a communication method provided by an embodiment of the present application. The description of the access network device and the terminal involved in FIG. 8 can be referred to the above, and will not be described in detail here. As shown in FIG. 8, the method comprises the following steps.

[0126] 801. The access network device sends downlink control information to the terminal.

[0127] Correspondingly, the terminal receives downlink control information from the access network device. The downlink control information is carried on the PDCCH. The downlink control information is used to schedule data transmission on the first CC. The first indication information in the downlink control information is used to indicate skipping the first RRM measurement. The time period in which the first RRM measurement is located is the first time period for RRM measurement corresponding (or associated) to the first CC, and the first time period for RRM measurement is the first time period for RRM measurement after the last symbol of the PDCCH is offset backward by the first time offset. Or, the time period in which the first RRM measurement is located is the first time period for RRM measurement on the first CC, and the first time period for RRM measurement is the first time period for RRM measurement after the last symbol of the PDCCH is offset backward by the first time offset. In this application, the time period is a short form of time period. Or, the first indication information in the downlink control information is used to indicate skipping the first RRM measurement on the first CC, and the first RRM measurement is the first RRM measurement in the periodic RRM measurement on the first CC, and the start time of the first RRM measurement is offset from the last symbol of the PDCCH by a time greater than or equal to the first time offset. Or, the first indication information in the downlink control information is used to indicate skipping the first RRM measurement on the first CC, and the first RRM measurement is the first RRM measurement in the periodic RRM measurement on the first CC, and the time offset between the last symbol of the PDCCH and the first RRM measurement is greater than or equal to the first time offset. Or, the first indication information in the downlink control information is used to indicate skipping the first RRM measurement on the first CC, and the first RRM measurement is the first RRM measurement satisfying the second condition in the periodic RRM measurement on the first CC, and the second condition includes that the time offset between the last symbol of the PDCCH and the first RRM measurement is greater than or equal to the first time offset. In this application, the RRM measurement can be an inter-frequency measurement or a positioning measurement within an MG (a time window), or an SSB measurement within an SMTC (a time window). The time period in which the RRM measurement is located is the MG or the SMTC.

[0128] In a possible design, the first indication information is 1 bit, and when the value of the first indication information is 1, it indicates skipping the first RRM measurement; and when the value of the first indication information is 0, it indicates not skipping the first RRM measurement. In another possible design, the first indication information is 1 bit, and when the value of the first indication information is 0, it indicates skipping the first RRM measurement; and when the value of the first indication information is 1, it indicates not skipping the first RRM measurement.

[0129] FIG. 9A and FIG. 9B are schematic diagrams of the first RRM measurement on the first CC according to the embodiments of the present application. As shown in FIG. 9A, the periodic RRM measurement on the first CC is in the order of RRM measurement 1, RRM measurement 2, RRM measurement 3, and so on, wherein the rectangular box containing the RRM measurement 1 represents the time period (or time window) in which the RRM measurement 1 is located, the rectangular box containing the RRM measurement 2 represents the time period in which the RRM measurement 2 is located, and the rectangular box containing the RRM measurement 3 represents the time period in which the RRM measurement 3 is located; the time indicated by the downward arrow is the time point corresponding to the last symbol of the PDCCH, the time period in which the RRM measurement 1 is located, the time period in which the RRM measurement 2 is located, and the time period in which the RRM measurement 3 is located are all after the time point, the time offset between the start time of the time period in which the RRM measurement 1 is located and the time point is greater than the first time offset, and the time period in which the RRM measurement 1 is located is the first time period for RRM measurement after the last symbol of the PDCCH is offset by the first time offset. The RRM measurement 1 in FIG. 9A is an example of the first RRM measurement. As shown in FIG. 9B, the periodic RRM measurement on the first CC is in the order of RRM measurement 1, RRM measurement 2, RRM measurement 3, and so on, wherein the rectangular box containing the RRM measurement 1 represents the time period (or time window) in which the RRM measurement 1 is located, the rectangular box containing the RRM measurement 2 represents the time period in which the RRM measurement 2 is located, and the rectangular box containing the RRM measurement 3 represents the time period in which the RRM measurement 3 is located; the time indicated by the downward arrow is the time point corresponding to the last symbol of the PDCCH, the time period in which the RRM measurement 1 is located, the time period in which the RRM measurement 2 is located, and the time period in which the RRM measurement 3 is located are all after the time point, the time offset between the start time of the time period in which the RRM measurement 1 is located and the time point is less than the first time offset, the time offset between the start time of the time period in which the RRM measurement 2 is located and the time point is greater than the first time offset, the time offset between the start time of the time period in which the RRM measurement 3 is located and the time point is greater than the first time offset, and the time period in which the RRM measurement 2 is located is the first time period for RRM measurement after the last symbol of the PDCCH is offset by the first time offset. The RRM measurement 2 in FIG. 9B is another example of the first RRM measurement.

[0130] The first time offset is related to the SCS of the first CC. In a possible design, the PDCCH is carried on the first CC, or in other words, the downlink control information is transmitted by the network device using the PDCCH on the first CC, and the first time offset is a time offset corresponding to the SCS of the first CC. Optionally, the terminal stores or is configured with a time offset corresponding to the SCS of the first CC; after receiving the downlink control information, the terminal takes the time offset corresponding to the SCS of the first CC as the first time offset. The network device can configure the terminal with a time offset corresponding to the SCS of the first CC. As an example, the network device sends offset configuration information to the terminal, where the offset configuration information is used to configure time offsets corresponding to F SCSs, F being an integer greater than 0; the terminal configures the time offsets corresponding to the F SCSs according to the offset configuration information, and the SCS of the first CC is any one of the F SCSs. The terminal can be preconfigured or stored with time offsets corresponding to F SCSs, and the SCS of the first CC is any one of the F SCSs. As an example, the SCS of the first CC is 15 kHz, and the time offset corresponding to the SCS of the first CC is 10 orthogonal frequency division multiplexing (OFDM) symbols; or the SCS of the first CC is 30 kHz, and the time offset corresponding to the SCS of the first CC is 12 OFDM symbols; or the SCS of the first CC is 60 kHz, and the time offset corresponding to the SCS of the first CC is 23 OFDM symbols; or the SCS of the first CC is 120 kHz, and the time offset corresponding to the SCS of the first CC is 36 OFDM symbols. The time offset corresponding to the SCS of the first CC is only an example. The specific value of the time offset corresponding to the SCS can be in units of slots, milliseconds, or the like, which is not limited in the application. Optionally, the terminal determines the time offset corresponding to the SCS of the first CC, and takes the time offset as the first time offset. After receiving the downlink control information, the terminal determines the time offset corresponding to the SCS of the first CC that carries the downlink control information, and takes the time offset corresponding to the SCS of the first CC as the first time offset. The terminal determines the time offset corresponding to the SCS of the first CC in any manner, which is not limited in the application. As an example, the time offset corresponding to the SCS can be pre-defined by a protocol, configured by a base station, reported by a terminal, or the like, which is not limited in the application.

[0131] In another possible design, the PDCCH is carried on the second CC, and the first time offset is the larger one of the time offset corresponding to the SCS of the first CC and the time offset corresponding to the SCS of the second CC. The downlink control information can be any one of DCI format 0_1, DCI format 1_1, DCI format 0_2, and DCI format 0_2 / 1_2. The carrier indicator field in the downlink control information indicates that the downlink control information is for the first CC. Optionally, the terminal stores or is configured with the time offset corresponding to the SCS of the first CC and the time offset corresponding to the SCS of the second CC, and after receiving the downlink control information, the terminal takes the larger one of the time offset corresponding to the SCS of the first CC and the time offset corresponding to the SCS of the second CC as the first time offset. The access network device can configure the terminal with the time offset corresponding to the SCS of the first CC and the time offset corresponding to the SCS of the second CC. As an example, the access network device sends offset configuration information to the terminal, where the offset configuration information is used to configure time offsets corresponding to H SCSs, and H is an integer greater than 1; and the terminal configures the time offsets corresponding to the H SCSs according to the offset configuration information, and the SCS of the first CC and the SCS of the second CC are any two of the H SCSs. The terminal can be pre-configured or stored with the time offsets corresponding to the H SCSs, and the SCS of the first CC and the SCS of the second CC are any two of the H SCSs. As an example, the SCS of the first CC is 15 kHz, the time offset corresponding to the SCS of the first CC is 1 / 15000, the SCS of the second CC is 30 kHz, and the time offset corresponding to the SCS of the second CC is 1 / 30000; or the SCS of the first CC is 30 kHz, the time offset corresponding to the SCS of the first CC is 1 / 30000, the SCS of the second CC is 60 kHz, and the time offset corresponding to the SCS of the second CC is 1 / 60000; or the SCS of the first CC is 60 kHz, the time offset corresponding to the SCS of the first CC is 1 / 60000, the SCS of the second CC is 120 kHz, and the time offset corresponding to the SCS of the second CC is 1 / 120000. Optionally, after receiving the downlink control information, the terminal determines the time offset corresponding to the SCS of the first CC and the time offset corresponding to the SCS of the second CC, and then takes the larger one of the time offset corresponding to the SCS of the first CC and the time offset corresponding to the SCS of the second CC as the first time offset. The terminal can determine the time offsets corresponding to the SCSs of different CCs in the same manner.

[0132] FIG. 9C is a schematic diagram of time offsets corresponding to SCSs of the first CC and time offsets corresponding to SCSs of the second CC according to an embodiment of the present application. As shown in FIG. 9C, the DCI carried on the second CC schedules data transmission on the first CC, the time indicated by the downward arrow is the time point corresponding to the last symbol of the PDCCH, the time offset #10 corresponding to the SCS of the second CC, the time offset #20 corresponding to the SCS of the first CC, the time offset #20 is greater than the time offset #10, the dashed box represents the period of time that the scheduled data transmission on the first CC needs to occupy, the solid box 10 represents the period of time in which the RRM measurement on the second CC is performed, and the solid box 20 represents the period of time in which the RRM measurement on the first CC is performed. In the schematic diagram of FIG. 9C, the first time offset is the time offset #20, and the terminal skips the RRM measurement on the first CC.

[0133] In a possible implementation, the RRM measurement configuration of the first CC and the RRM measurement configuration of the second CC are the same. The RRM measurement configuration of the first CC and the RRM measurement configuration of the second CC can be uniformly configured. As an example, the RRM measurement configuration of the first CC and the RRM measurement configuration of the second CC are configured in a terminal granularity, or in other words, the RRM measurement configuration of the first CC and the RRM measurement configuration of the second CC are configured per UE. In this example, the RRM measurement configuration of the terminal on all CCs is the same. The RRM measurement configuration of the first CC and the RRM measurement configuration of the second CC can be separately configured. As an example, the RRM measurement configuration of the first CC and the RRM measurement configuration of the second CC are configured in a frequency granularity, which can be any one of a frequency band (or in other words, per band configuration), a frequency point (or in other words, per frequency point configuration), a frequency range (or in other words, per FR configuration), a bandwidth part (or in other words, per BWP configuration), or a band combination (or in other words, per band combination configuration). The following takes the frequency band granularity configuration and the frequency range granularity configuration as examples for illustration. The frequency band granularity configuration can be to separately configure the RRM measurement configuration corresponding to each frequency band, the RRM measurement configuration of the first CC is the RRM measurement configuration corresponding to the frequency band to which the first CC belongs, and the RRM measurement configuration of the second CC is the RRM measurement configuration corresponding to the frequency band to which the second CC belongs. The frequency range granularity configuration can be to separately configure the RRM measurement configuration corresponding to each frequency range, the RRM measurement configuration of the first CC is the RRM measurement configuration corresponding to the frequency range to which the first CC belongs, and the RRM measurement configuration of the second CC is the RRM measurement configuration corresponding to the frequency range to which the second CC belongs.

[0134] In another possible implementation, the RRM measurement configuration of the first CC and the RRM measurement configuration of the second CC are different. The RRM measurement configuration of the first CC and the RRM measurement configuration of the second CC can be configured respectively. As an example, the RRM measurement configuration of the first CC and the RRM measurement configuration of the second CC are configured with a frequency granularity, which can be any one of configured with a frequency band granularity, configured with a frequency point granularity, configured with a FR granularity, configured with a BWP granularity, or configured with a frequency band combination granularity.

[0135] 802、The terminal skips the first RRM measurement on the first CC based on the downlink control information, the time period in which the first RRM measurement is located being the first time period for RRM measurement after the last symbol of the PDCCH is offset backward by the first time offset.

[0136] Alternatively, the terminal performs data transmission on the first CC based on the downlink control information, wherein the time period in which the first RRM measurement is located is available for data transmission on the first CC, i.e., the time period in which the first RRM measurement is located is available for data transmission on the first CC. The terminal can perform data transmission on the first CC in the time period in which the first RRM measurement is located. Alternatively, the terminal performs data transmission on the first CC based on the downlink control information, wherein the time period in which the terminal performs data transmission on the first CC can include the time period in which the first RRM measurement is located or a part of the time period in which the first RRM measurement is located, or can not include any part of the time period in which the first RRM measurement is located. The terminal skipping the first RRM measurement on the first CC can mean that the terminal does not perform RRM measurement on the first CC in the time period in which the first RRM measurement is located.

[0137] In a possible implementation, the terminal performs data transmission on the first CC based on the downlink control information, wherein the terminal has a requirement of performing data transmission on the first CC in a time period in which the first RRM measurement is performed, and the time period in which the terminal performs data transmission on the first CC includes the time period in which the first RRM measurement is performed or a part of the time period in which the first RRM measurement is performed. The requirement of the terminal of performing data transmission on the first CC in the time period in which the first RRM measurement is performed can be that the time domain resource allocated by the downlink control information for scheduling data transmission on the first CC includes the time period in which the first RRM measurement is performed or a part of the time period in which the first RRM measurement is performed, or in other words, the time period required to be occupied by the data transmission on the first CC scheduled by the downlink control information includes the time period in which the first RRM measurement is performed or a part of the time period in which the first RRM measurement is performed. FIG. 10A is a schematic diagram of the terminal skipping the first RRM measurement on the first CC according to an embodiment of the present application. As shown in FIG. 10A, the DCI (i.e., the downlink control information) is carried on the first CC, the time indicated by the downward arrow is the time point corresponding to the last symbol of the PDCCH, the dashed rectangular box represents the time period (or time window) required to be occupied by the data transmission on the first CC scheduled by the downlink control information, the solid rectangular box represents the time period in which the periodic RRM measurement on the first CC is performed, and the rectangular box indicated by 101A represents the time period in which the first RRM measurement skipped according to the first indication information in the downlink control information. The time period required to be occupied by the data transmission on the first CC scheduled by the downlink control information partially overlaps with the time period in which the first RRM measurement is performed, the terminal skips the first RRM measurement, the time period in which the terminal performs data transmission on the first CC is the time period required to be occupied by the data transmission on the first CC scheduled by the downlink control information, and the time period in which the terminal performs data transmission on the first CC includes a part of the time period in which the first RRM measurement is performed, i.e., the part of the time period in which the first RRM measurement is performed that overlaps with the time period required to be occupied by the data transmission on the first CC. It should be understood that if the time period in which the first RRM measurement is performed is entirely included in the time period required to be occupied by the data transmission on the first CC, the time period in which the terminal performs data transmission on the first CC includes the time period in which the first RRM measurement is performed. In the schematic diagram shown in FIG. 10A, the terminal skips the first RRM measurement, and the RRM measurement on the first CC does not cause scheduling restriction to the data transmission on the first CC by the terminal, i.e., the data transmission on the first CC by the terminal is not affected by the RRM measurement.

[0138] Figure 10B is a schematic diagram illustrating a terminal skipping a first RRM measurement on a first CC according to an embodiment of the present application. As shown in Figure 10B, the DCI (i.e. downlink control information) is carried on a second CC, the time indicated by the downward arrow is the time point corresponding to the last symbol of the PDCCH, the dashed rectangular box represents the time period occupied by the data transmission on the first CC scheduled by the downlink control information, the solid rectangular box represents the time period in which the periodic RRM measurement on the first CC is located, the rectangular box indicated by 101B represents the time period in which the first RRM measurement indicated by the first indication information in the downlink control information is skipped, there is an overlap between the time period occupied by the data transmission on the first CC scheduled by the downlink control information and the time period in which the first RRM measurement is located, the terminal skips the first RRM measurement, and the time period in which the terminal performs data transmission on the first CC is the time period occupied by the data transmission on the first CC scheduled by the downlink control information, and the time period in which the terminal performs data transmission on the first CC includes the time period in which the first RRM measurement is located or a part of the time period in which the first RRM measurement is located. In the schematic diagram shown in Figure 10B, the terminal skips the first RRM measurement, and the RRM measurement on the first CC by the terminal does not cause scheduling restriction to the data transmission on the first CC by the terminal.

[0139] In another possible implementation, the terminal performs data transmission on the first CC based on the downlink control information, wherein the terminal has no need to perform data transmission on the first CC in the time period in which the first RRM measurement is performed, and the time period in which the terminal performs data transmission on the first CC does not include any part of the time period in which the first RRM measurement is performed. The terminal has no need to perform data transmission on the first CC in the time period in which the first RRM measurement is performed can be that the time domain resource allocated by the downlink control information for scheduling data transmission on the first CC does not include any part of the time period in which the first RRM measurement is performed, or in other words, the time period required to be occupied by the data transmission on the first CC scheduled by the downlink control information does not include any part of the time period in which the first RRM measurement is performed. FIG. 11A is a schematic diagram of the terminal skipping the first RRM measurement on the first CC according to an embodiment of the present application. As shown in FIG. 11A, the DCI (i.e., the downlink control information) is carried on the first CC, the time indicated by the downward arrow is the time point corresponding to the last symbol of the PDCCH, the dashed rectangular box represents the time period required to be occupied by the data transmission on the first CC scheduled by the downlink control information, the solid rectangular box represents the time period in which the periodic RRM measurement on the first CC is performed, the rectangular box indicated by 111A represents the time period in which the first RRM measurement is performed, the time period required to be occupied by the data transmission on the first CC scheduled by the downlink control information does not overlap with the time period in which the first RRM measurement is performed, the terminal skips the first RRM measurement, and the time period in which the terminal performs data transmission on the first CC is the time period required to be occupied by the data transmission on the first CC scheduled by the downlink control information. In the schematic diagram shown in FIG. 11A, the terminal skips the first RRM measurement, the RRM measurement on the first CC performed by the terminal does not cause scheduling restriction to the data transmission on the first CC performed by the terminal, that is, the data transmission on the first CC performed by the terminal is not affected by the RRM measurement.

[0140] FIG. 11B is a schematic diagram of skipping, by a terminal, a first RRM measurement on a first CC according to an embodiment of the present application. As shown in FIG. 11B, DCI (i.e., downlink control information) is carried on a second CC, the time indicated by the downward arrow corresponds to a time point of a last symbol of a PDCCH, the dashed rectangular box represents a time period occupied by data transmission on the first CC scheduled by the downlink control information, the solid rectangular box represents a time period in which a periodic RRM measurement on the first CC is located, the rectangular box indicated by 111B represents a time period in which the first RRM measurement is located, the time period occupied by the data transmission on the first CC scheduled by the downlink control information does not overlap with the time period in which the first RRM measurement is located, the terminal skips the first RRM measurement, and the time period in which the terminal performs data transmission on the first CC is the time period occupied by the data transmission on the first CC scheduled by the downlink control information, and the time period in which the terminal performs data transmission on the first CC does not include any part of the time period in which the first RRM measurement is located. In the schematic diagram shown in FIG. 11B, the terminal skips the first RRM measurement, and the RRM measurement on the first CC by the terminal does not cause scheduling restriction to data transmission on the first CC by the terminal.

[0141] In the embodiments of the present application, the terminal skips the first RRM measurement on the first CC based on the downlink control information, so that the RRM measurement on the first CC by the terminal does not cause scheduling restriction to data transmission on the first CC by the terminal, and the latency of data transmission can be reduced.

[0142] FIG. 12 is a flowchart of another communication method according to an embodiment of the present application. The communication method of FIG. 12 describes a process of skipping, with terminal granularity, RRM measurement on multiple CCs. The communication method of FIG. 12 is a possible example of the communication method of FIG. 8. As shown in FIG. 12, the method includes the following steps.

[0143] 1201. The terminal sends first capability information to the access network device.

[0144] Correspondingly, the access network device receives the first capability information from the terminal. The first capability information is used to report that the terminal has the capability of skipping RRM measurement with terminal granularity. Alternatively, the first capability information is used to report that the terminal has the capability of supporting DCI indicating the terminal to skip RRM measurement with terminal granularity. The first capability information can include identification information of the terminal. The skipping of RRM measurement with terminal granularity can be that the RRM measurement configuration of the terminal on all CCs is the same, and the terminal simultaneously skips RRM measurement on all CCs. The first capability information can be carried in high-layer signaling, such as RRC signaling.

[0145] 1202. In response to the first capability information, the access network device sends first configuration information to the terminal.

[0146] Correspondingly, the terminal receives first configuration information from the access network device. The first configuration information contains RRM measurement configuration configured in terminal granularity. In other words, the first configuration information contains configuration parameters of RRM measurement configured in terminal granularity. The first configuration information sent by the access network device matches the first capability information. In other words, the granularity of RRM measurement configured by the first configuration information sent by the access network device is the same as the granularity of skipped RRM measurement reported by the first capability information sent by the terminal. The first configuration information can be carried in RRC signaling. The RRM measurement configuration can be the configuration of the MG or the configuration of the SMTC. As an example, the RRM measurement configuration is the configuration of the MG, and the first configuration information includes the MGRP, the MGL, and the gap offset. As another example, the RRM measurement configuration is the configuration of the SMTC, and the first configuration information includes the SMTC periodicity, the SMTC offset, and the SMTC duration.

[0147] 1203. The terminal configures the configuration parameters of the RRM measurement based on the first configuration information.

[0148] As an example, the RRM measurement configuration is the configuration of the MG, and the configuration parameters of the RRM measurement include the MGRP, the MGL, and the gap offset. As another example, the RRM measurement configuration is the configuration of the SMTC, and the configuration parameters of the RRM measurement include the SMTC periodicity, the SMTC offset, and the SMTC duration. After the terminal configures the configuration parameters of the RRM measurement based on the first configuration information, the terminal can perform RRM measurement according to the configuration parameters.

[0149] Steps 1201 to 1203 are steps in which the access network device configures the configuration parameters of the RRM measurement for the terminal. Steps 1201 to 1203 are optional. As an example, after the terminal configures the configuration parameters of the RRM measurement, the terminal does not have to perform steps 1201 to 1203 subsequently.

[0150] 1204. The access network device sends downlink control information to the terminal.

[0151] Correspondingly, the terminal receives the downlink control information from the access network device. Step 1204 can refer to step 801 in FIG. 8.

[0152] 1205. The terminal skips the first RRM measurement on the first CC and the RRM measurements on other CCs that are in the same period as the first RRM measurement based on the downlink control information.

[0153] The terminal performs RRM measurement on the first CC and performs RRM measurement on other CCs at the same time. For example, the terminal performs RRM measurement on a plurality of CCs including the first CC, and the other CCs refer to all CCs in the plurality of CCs except the first CC.

[0154] In the embodiment of the application, the terminal receives the first configuration information, the RRM measurement configuration configured in the terminal granularity in the first configuration information matches the capability of the terminal to skip RRM measurement in the terminal granularity, so that the terminal can skip RRM measurement in the terminal granularity. The terminal skips RRM measurement in the terminal granularity, and does not have to indicate to skip RRM measurement on different CCs through different DCIs, which can save the signaling overhead of DCI.

[0155] FIG. 13 is a flowchart of another communication method provided by an embodiment of the application. The communication method of FIG. 13 describes a process in which a terminal skips RRM measurement on a CC in a frequency granularity. The communication method of FIG. 13 is another possible example of the communication method of FIG. 8. As shown in FIG. 13, the method includes the following steps.

[0156] 1301. The terminal sends second capability information to the access network device.

[0157] Correspondingly, the access network device receives the second capability information from the terminal. The second capability information is used to report the capability of the terminal to skip RRM measurement in a frequency granularity. Alternatively, the second capability information is used to report the capability of the terminal to support DCI indicating the terminal to skip RRM measurement in a frequency granularity. The capability of skipping RRM measurement in a frequency granularity can include one or more of the following: the capability of skipping RRM measurement in a frequency band granularity, the capability of skipping RRM measurement in a frequency point granularity, the capability of skipping RRM measurement in a FR granularity, the capability of skipping RRM measurement in a BWP granularity, or the capability of skipping RRM measurement in a frequency band combination granularity. Optionally, the second capability information is also used to report the capability of the terminal to skip RRM measurement in a terminal granularity. The second capability information can include the identification information of the terminal. As an example of skipping RRM measurement in a frequency granularity, the RRM measurement configuration of the terminal on different CCs is different, and the terminal performs RRM measurement on each CC respectively (independently). As an example, the first indication information in the downlink control information sent by the access network device is used to indicate to skip the first RRM measurement on the first CC, and the terminal only skips the first RRM measurement on the first CC, without skipping RRM measurement on other CCs. The second capability information can be carried in high-layer signaling, such as RRC signaling.

[0158] 1302. In response to the second capability information, the access network device sends second configuration information to the terminal.

[0159] Correspondingly, the terminal receives second configuration information from the access network device. The second configuration information contains RRM measurement configuration configured in frequency granularity. Alternatively, the second configuration information contains configuration parameters of RRM measurement configured in frequency granularity. The second configuration information sent by the access network device matches the second capability information described above. Optionally, if the terminal does not have the capability of skipping RRM measurement in a certain granularity, the second configuration information does not contain the configuration parameters of RRM measurement configured in the granularity. The second configuration information can be carried in RRC signaling. The RRM measurement configuration can be the configuration of the MG described above, or the configuration of the SMTC. As an example, the RRM measurement configuration is the configuration of the MG, and the second configuration information includes the MGRP, the MGL and the gap offset corresponding to a plurality of frequency points respectively. As another example, the RRM measurement configuration is the configuration of the MG, and the second configuration information includes the MGRP, the MGL and the gap offset corresponding to a plurality of FRs respectively. As another example, the RRM measurement configuration is the configuration of the SMTC, and the second configuration information includes the SMTC period, the SMTC offset and the SMTC duration corresponding to a plurality of frequency points respectively. As another example, the RRM measurement configuration is the configuration of the SMTC, and the second configuration information includes the SMTC period, the SMTC offset and the SMTC duration corresponding to a plurality of FRs respectively.

[0160] 1303、The terminal configures the configuration parameters of RRM measurement based on the second configuration information.

[0161] As an example, the RRM measurement configuration is the configuration of the MG, and the configuration parameters of the RRM measurement comprise the MGRP, the MGL and the gap offset corresponding to the plurality of frequency points respectively. As an example, the RRM measurement configuration is the configuration of the MG, and the configuration parameters of the RRM measurement comprise the MGRP, the MGL and the gap offset corresponding to the plurality of FRs respectively. As another example, the RRM measurement configuration is the configuration of the SMTC, and the configuration parameters of the RRM measurement comprise the SMTC period, the SMTC offset and the SMTC duration corresponding to the plurality of frequency points respectively. As another example, the RRM measurement configuration is the configuration of the SMTC, and the configuration parameters of the RRM measurement comprise the SMTC period, the SMTC offset and the SMTC duration corresponding to the plurality of FRs respectively. Based on the second configuration information, the terminal can determine the configuration parameters of the RRM measurement on each CC available to the terminal. As an example, the configuration parameters of the RRM measurement comprise the MGRP, the MGL and the gap offset corresponding to the plurality of frequency points respectively, and the RRM measurement configuration of the first CC is the RRM measurement configuration corresponding to the frequency point where the first CC is located. As an example, the configuration parameters of the RRM measurement comprise the MGRP, the MGL and the gap offset corresponding to the plurality of FRs respectively, and the RRM measurement configuration of the first CC is the RRM measurement configuration corresponding to the FR to which the first CC belongs. After the terminal configures the configuration parameters of the RRM measurement based on the second configuration information, the terminal can perform the RRM measurement according to the configuration parameters.

[0162] Steps 1301 to 1303 are steps in which the access network device configures the terminal with the configuration parameters of the RRM measurement. Steps 1301 to 1303 are optional. As an example, after the terminal configures the configuration parameters of the RRM measurement, the terminal does not have to perform steps 1301 to 1303 subsequently.

[0163] 1304. The access network device sends downlink control information to the terminal.

[0164] Correspondingly, the terminal receives the downlink control information from the access network device. Step 1304 can refer to step 801 in FIG. 8.

[0165] 1305. The terminal skips the first RRM measurement on the first CC based on the downlink control information.

[0166] Step 1305 can refer to step 802 in FIG. 8.

[0167] In the embodiments of the present application, the terminal receives the second configuration information, the RRM measurement configuration included in the second configuration information is configured with frequency granularity and matches the capability of the terminal to skip the RRM measurement with frequency granularity, so that the terminal can skip the RRM measurement with frequency granularity. The terminal skips the RRM measurement with frequency granularity, which can reduce the influence of the RRM measurement skipping on the measurement performance.

[0168] FIG. 14 is a flow diagram of another method of communication provided by the embodiments of the present application. The method of communication of FIG. 14 is similar to the method of communication of FIG. 8, except that the terminal can skip RRM measurement on multiple CCs based on the downlink control information. As shown in FIG. 14, the method can include the following steps.

[0169] 1401. The access network device sends downlink control information to the terminal.

[0170] Correspondingly, the terminal receives the downlink control information from the access network device. The downlink control information is carried in a PDCCH. The downlink control information is used to schedule data transmission on a first CC. First indication information in the downlink control information is used to indicate skipping of a first RRM measurement. The description of the downlink control information can refer to the description of the downlink control information in step 801 above, which will not be repeated here.

[0171] The first time offset is related to the SCS of the first CC. In one possible design, the PDCCH is carried in the first CC, or in other words, the downlink control information is sent by the access network device using the PDCCH on the first CC, and the first time offset is a time offset corresponding to the SCS of the first CC. Optionally, the terminal stores or is configured with time offsets corresponding to the SCSs of the first CC; after receiving the downlink control information, the terminal takes the time offset corresponding to the SCS of the first CC carrying the downlink control information as the first time offset. The access network device can configure the terminal with the time offset corresponding to the SCS of the first CC. As an example, the access network device sends offset configuration information to the terminal, the offset configuration information being used to configure time offsets corresponding to F SCSs, F being an integer greater than 0; the terminal configures the time offsets corresponding to the F SCSs according to the offset configuration information, the SCS of the first CC being any one of the F SCSs. The terminal can be preconfigured or stored with time offsets corresponding to the F SCSs, the SCS of the first CC being any one of the F SCSs. Optionally, the terminal determines the time offset corresponding to the SCS of the first CC, and takes the time offset as the first time offset. After receiving the downlink control information, the terminal determines the time offset corresponding to the SCS of the first CC carrying the downlink control information, and takes the time offset corresponding to the SCS of the first CC as the first time offset. The terminal determines the time offset corresponding to the SCS of the first CC in any manner.

[0172] In another possible design, the PDCCH is carried on the second CC, and the first time offset is the larger one of the time offset corresponding to the SCS of the first CC and the time offset corresponding to the SCS of the second CC. Optionally, the terminal stores or is configured with the time offset corresponding to the SCS of the first CC and the time offset corresponding to the SCS of the second CC, and after receiving the downlink control information, the terminal takes the larger one of the time offset corresponding to the SCS of the first CC and the time offset corresponding to the SCS of the second CC as the first time offset. The access network device can configure the terminal with the time offset corresponding to the SCS of the first CC and the time offset corresponding to the SCS of the second CC. As an example, the access network device sends offset configuration information to the terminal, where the offset configuration information is used to configure time offsets corresponding to H SCs, and H is an integer greater than 1; and the terminal configures the time offsets corresponding to the H SCs according to the offset configuration information, and the SCS of the first CC and the SCS of the second CC are any two of the H SCs. The terminal can be pre-configured or stored with the time offsets corresponding to the H SCs, and the SCS of the first CC and the SCS of the second CC are any two of the H SCs. Optionally, after receiving the downlink control information, the terminal determines the time offset corresponding to the SCS of the first CC and the time offset corresponding to the SCS of the second CC, and then takes the larger one of the time offset corresponding to the SCS of the first CC and the time offset corresponding to the SCS of the second CC as the first time offset.

[0173] In a possible implementation, the RRM measurement configuration of the first CC and the RRM measurement configuration of the second CC are the same. The RRM measurement configuration of the first CC and the RRM measurement configuration of the second CC can be uniformly configured. As an example, the RRM measurement configuration of the first CC and the RRM measurement configuration of the second CC are configured in a terminal granularity, or in other words, the RRM measurement configuration of the first CC and the RRM measurement configuration of the second CC are configured per UE. In this example, the RRM measurement configuration of the terminal on all CCs is the same. The RRM measurement configuration of the first CC and the RRM measurement configuration of the second CC can be separately configured. As an example, the RRM measurement configuration of the first CC and the RRM measurement configuration of the second CC are configured in a frequency granularity.

[0174] In another possible implementation, the RRM measurement configuration of the first CC and the RRM measurement configuration of the second CC are different. The RRM measurement configuration of the first CC and the RRM measurement configuration of the second CC can be separately configured. As an example, the RRM measurement configuration of the first CC and the RRM measurement configuration of the second CC are configured in a frequency granularity. The configuration in a frequency granularity can be any one of configuration in a frequency band granularity, configuration in a frequency point granularity, configuration in a FR granularity, configuration in a BWP granularity, or configuration in a frequency band combination granularity.

[0175] 1402、The terminal skips the first RRM measurement on the first CC based on the downlink control information, and also skips the second RRM measurement on the third CC in a case where at least the first condition is satisfied, a time period where the first RRM measurement is located being a first time period for RRM measurement after a last symbol of PDCCH is offset backward by a first time offset.

[0176] Alternatively, the terminal performs data transmission on the first CC based on the downlink control information, wherein the time period where the first RRM measurement is located and the time period where the second RRM measurement on the third CC are both available for data transmission on the first CC, i.e., the time period where the first RRM measurement is located and the time period where the second RRM measurement on the third CC are available for data transmission on the first CC. The terminal can perform data transmission on the first CC in the time period where the first RRM measurement is located and the time period where the second RRM measurement on the third CC is located. Alternatively, the terminal performs data transmission on the first CC based on the downlink control information, wherein a time period where the terminal performs data transmission on the first CC can include one or more of the following: the time period where the first RRM measurement is located, a part of the time period where the first RRM measurement is located, the time period where the second RRM measurement on the third CC is located, and a part of the time period where the second RRM measurement on the third CC is located. The terminal skipping the first RRM measurement on the first CC can mean that the terminal does not perform RRM measurement on the first CC in the time period where the first RRM measurement is located. The terminal skipping the second RRM measurement on the third CC can mean that the terminal does not perform RRM measurement on the third CC in the time period where the second RRM measurement is located. The specific implementation of skipping the first RRM measurement on the first CC and skipping the second RRM measurement on the third CC can refer to the description of skipping the first RRM measurement on the first CC in the method flow of FIG. 8, which will not be repeated here.

[0177] The first condition includes any of the following: a time period in which the second RRM measurement is performed overlaps in time domain with a time period in which the first RRM measurement is performed, or a start time of the time period in which the second RRM measurement is performed is separated from an end time of the time period in which the first RRM measurement is performed by less than or equal to a first threshold. The first threshold can be set according to actual needs, which is not limited here. For example, the first threshold is 100 us, 200 us, 500 us, 1 ms, 2 ms, etc. In this application, overlap includes partial overlap and complete overlap. The time period in which the second RRM measurement is performed overlaps in time domain with the time period in which the first RRM measurement is performed can be understood as part or all of the time period in which the second RRM measurement is performed is contained in the time period in which the first RRM measurement is performed. The above first condition is for RRM measurement on the third CC. The terminal can determine whether to skip the RRM measurement to be performed on each CC in a similar or same manner. As an example, if the above first condition further includes: a time period in which the third RRM measurement on the fourth CC is performed overlaps in time domain with the time period in which the first RRM measurement is performed, or a start time of the time period in which the third RRM measurement is performed is separated from an end time of the time period in which the first RRM measurement is performed by less than or equal to the first threshold; the terminal also skips the third RRM measurement on the fourth CC based on the downlink control information.

[0178] In a possible design, when a certain RRM measurement to be performed by the terminal on an arbitrary CC meets a target condition, the terminal also skips the RRM measurement on the arbitrary CC based on the downlink control information; where the target condition is that a time period in which the RRM measurement is performed overlaps in time domain with a time period in which the first RRM measurement is performed, or a start time of the time period in which the RRM measurement is performed is separated from an end time of the time period in which the first RRM measurement is performed by less than or equal to a first threshold. As an example, after the terminal receives the downlink control information, the terminal determines the RRM measurements to be performed on each CC that meet the target condition respectively; then, the first RRM measurement on the first CC is skipped, and the RRM measurements to be performed on each CC that meet the target condition are skipped. Skipping the RRM measurement to be performed on the third CC that meets the target condition can be described as: in the case of at least meeting the first condition, the second RRM measurement on the third CC is skipped, and the first condition and the target condition are the same for the third CC.

[0179] In the embodiments of the present application, the terminal skips the first RRM measurement on the first CC based on the downlink control information, and also skips the second RRM measurement on the third CC in the case that at least the first condition is met; thus, the RRM measurement of the terminal on each CC does not cause scheduling restriction on data transmission of the terminal on the first CC, and the latency of data transmission can be reduced. In addition, the terminal skips the second RRM measurement on the third CC based on the downlink control information in the case that at least the first condition is met, and does not have to indicate skipping the second RRM measurement on the third CC through other DCI, which can save signaling overhead.

[0180] FIG. 15 is a flow diagram of another communication method provided in the embodiments of the present application. The communication method of FIG. 15 describes a process of skipping RRM measurement on a CC with frequency granularity. The communication method of FIG. 15 is a possible example of the communication method of FIG. 14. As shown in FIG. 15, the method includes:

[0181] 1501. The terminal sends second capability information to the access network device.

[0182] Correspondingly, the access network device receives the second capability information from the terminal. Steps 1501 to 1503 can refer to steps 1301 to 1303 in FIG. 13.

[0183] 1502. The access network device sends second configuration information to the terminal in response to the second capability information.

[0184] Correspondingly, the terminal receives the second configuration information from the access network device.

[0185] 1503. The terminal configures the configuration parameter of RRM measurement based on the second configuration information.

[0186] Steps 1501 to 1503 are steps of the access network device configuring the configuration parameter of RRM measurement for the terminal. Steps 1501 to 1503 are optional. As an example, the terminal does not have to perform steps 1501 to 1503 subsequently after configuring the configuration parameter of RRM measurement.

[0187] 1504. The access network device sends downlink control information to the terminal.

[0188] Correspondingly, the terminal receives the downlink control information from the access network device. Step 1504 can refer to step 1401 in FIG. 14.

[0189] 1505、The terminal skips the first RRM measurement on the first CC based on the downlink control information, and also skips the second RRM measurement on the third CC in the case that at least the first condition is satisfied, the time period in which the first RRM measurement is located being the first time period for RRM measurement after the last symbol of the PDCCH is offset backward by the first time offset.

[0190] In the embodiments of the present application, the terminal receives the second configuration information, the RRM measurement configuration configured with the frequency granularity in the second configuration information matches the capability of the terminal to skip the RRM measurement with the frequency granularity, so that the terminal can skip the RRM measurement with the frequency granularity. The terminal skips the RRM measurement with the frequency granularity, which can reduce the influence of the RRM measurement skipping on the measurement performance. The terminal skips the first RRM measurement on the first CC based on the downlink control information, and also skips the second RRM measurement on the third CC in the case that at least the first condition is satisfied, so that the RRM measurement of the terminal on each CC does not cause scheduling restriction on the data transmission of the terminal on the first CC, which can reduce the latency of the data transmission and save the signaling overhead.

[0191] FIG. 16 is a flow diagram of another communication method provided by the embodiments of the present application. The communication method of FIG. 16 is different from the communication method of FIG. 8 in that the first indication information in the downlink control information has different functions. In the communication method of FIG. 16, the first indication information in the downlink control information is used to indicate that the terminal is allowed to skip the first RRM measurement. As shown in FIG. 16, the method includes:

[0192] 1601、The access network device sends the downlink control information to the terminal.

[0193] Correspondingly, the terminal receives the downlink control information from the access network device. The downlink control information is carried in the PDCCH. The downlink control information is used to schedule the data transmission on the first CC. The first indication information in the downlink control information is used to indicate that the first RRM measurement is allowed to be skipped. For example, the downlink control information contains the identification information of the terminal, and the first indication information is used to indicate that the terminal is allowed to skip the first RRM measurement. The terminal can decide by itself whether to skip the first RRM measurement. That is, the terminal can skip the first RRM measurement based on the downlink control information, or not skip the first RRM measurement, that is, perform the first RRM measurement. Optionally, the communication method of FIG. 16 can also include the steps 1301 to 1303 in FIG. 13.

[0194] The time period in which the first RRM measurement is located is the first time period for RRM measurement in the periodic time period corresponding (or associated) to the first CC, and the last symbol of the PDCCH is offset to the first time period for RRM measurement after the first time offset. Or, the time period in which the first RRM measurement is located is the first time period for RRM measurement in the periodic time period on the first CC, and the last symbol of the PDCCH is offset to the first time period for RRM measurement after the first time offset. Or, the first indication information in the downlink control information is used to indicate that the first RRM measurement on the first CC is allowed to be skipped, and the first RRM measurement is the first RRM measurement in the periodic RRM measurement on the first CC, and the starting time of the first RRM measurement is greater than or equal to the first time offset from the last symbol of the PDCCH. Or, the first indication information in the downlink control information is used to indicate that the first RRM measurement on the first CC is allowed to be skipped, and the first RRM measurement is the first RRM measurement in the periodic RRM measurement on the first CC, and the time offset between the last symbol of the PDCCH and the first RRM measurement is greater than or equal to the first time offset. Please refer to the description of FIG. 9A and FIG. 9B above, the RRM measurement 1 in FIG. 9A is an example of the first RRM measurement, and the RRM measurement 2 in FIG. 9B is another example of the first RRM measurement.

[0195] In a possible design, the first indication information is 1 bit, and when the value of the first indication information is 1, it indicates that the first RRM measurement is allowed to be skipped; and when the value of the first indication information is 0, it indicates that the first RRM measurement is not allowed to be skipped. In another possible design, the first indication information is 1 bit, and when the value of the first indication information is 0, it indicates that the first RRM measurement is allowed to be skipped; and when the value of the first indication information is 1, it indicates that the first RRM measurement is not allowed to be skipped.

[0196] The first time offset is related to the SCS of the first CC. In a possible design, the PDCCH is carried on the first CC, or the downlink control information is sent by the access network device using the PDCCH on the first CC, and the first time offset is a time offset corresponding to the SCS of the first CC. In another possible design, the PDCCH is carried on the second CC, and the first time offset is the larger one of a time offset corresponding to the SCS of the first CC and a time offset corresponding to the SCS of the second CC.

[0197] 1602. The terminal skips the first RRM measurement on the first CC based on the downlink control information when the third condition is met, or performs the first RRM measurement on the first CC when the third condition is not met.

[0198] The third condition includes any one of the following: a time period required for the data transmission on the first CC scheduled by the downlink control information overlaps in time domain with the time period of the first RRM measurement, i.e., the time domain resource allocated by the downlink control information for scheduling the data transmission on the first CC includes the time period of the first RRM measurement or a part of the time period of the first RRM measurement, and the interval between the start time of the time period of the first RRM measurement and the end time of the time period required for the data transmission on the first CC scheduled by the downlink control information is less than or equal to a second threshold. The first threshold can be set according to actual needs, which is not limited here. For example, the first threshold is 100us, 200us, 500us, 1ms, 2ms, etc. For ease of description, the third condition is described below as an example that the time period required for the data transmission on the first CC scheduled by the downlink control information overlaps in time domain with the time period of the first RRM measurement.

[0199] Step 1602 can be replaced by: the terminal performs data transmission on the first CC based on the downlink control information, wherein the time period of the first RRM measurement is available for the data transmission on the first CC, i.e., the time period of the first RRM measurement is available for the data transmission on the first CC; in the case where the third condition is met, the terminal skips the first RRM measurement on the first CC, and the time period in which the terminal performs data transmission on the first CC includes the time period of the first RRM measurement or a part of the time period of the first RRM measurement; in the case where the third condition is not met, the terminal performs the first RRM measurement on the first CC.

[0200] Multiplexing Figure 11A, the DCI (i.e., the downlink control information) is carried on the first CC, the solid rectangular frame represents the time period required for the data transmission on the first CC scheduled by the downlink control information, the dashed rectangular frame represents the time period of the periodic RRM measurement on the first CC, and the rectangular frame pointed to by 111A represents the time period of the above-mentioned first RRM measurement. There is an overlap between the time period required for the data transmission on the first CC scheduled by the downlink control information and the time period of the first RRM measurement, i.e., the third condition is met, the terminal skips the first RRM measurement, and the time period in which the terminal performs data transmission on the first CC is the time period required for the data transmission on the first CC scheduled by the downlink control information. In the schematic diagram shown in Figure 11A, the terminal skips the first RRM measurement, and the RRM measurement of the terminal on the first CC does not cause scheduling restriction to the data transmission of the terminal on the first CC, i.e., the data transmission of the terminal on the first CC is not affected by the RRM measurement.

[0201] Figure 11B is a schematic diagram of multiplexing of DCI (i.e. downlink control information) carried on the second CC, the solid rectangular block represents a time period occupied by the data transmission on the first CC scheduled by the downlink control information, the dashed rectangular block represents a time period in which the periodic RRM measurement on the first CC is performed, the rectangular block indicated by 111B represents the time period in which the first RRM measurement is performed, the time period occupied by the data transmission on the first CC scheduled by the downlink control information does not overlap with the time period in which the first RRM measurement is performed, i.e. the third condition is not satisfied, the terminal does not skip the first RRM measurement, the time period in which the terminal performs the data transmission on the first CC is the time period occupied by the data transmission on the first CC scheduled by the downlink control information, and the time period in which the terminal performs the data transmission on the first CC does not include any part of the time period in which the first RRM measurement is performed. In the schematic diagram shown in Figure 11B, the terminal does not skip the first RRM measurement, the terminal performs the first RRM measurement, and no scheduling restriction is caused to the data transmission of the terminal on the first CC.

[0202] In the embodiments of the present application, the terminal skips the first RRM measurement on the first CC based on the downlink control information when the third condition is satisfied, thereby reducing the scheduling restriction caused by the RRM measurement on the first CC to the data transmission of the terminal on the first CC, or performs the first RRM measurement on the first CC when the third condition is not satisfied, thereby reducing the influence of the RRM measurement skipping on the measurement performance.

[0203] Figure 17 is a flowchart of another communication method provided by the embodiments of the present application. The communication method of Figure 17 is different from the communication method of Figure 16 in that the terminal can skip the first RRM measurement and other RRM measurements based on the downlink control information. As shown in Figure 17, the method comprises:

[0204] 1701. The access network device sends downlink control information to the terminal.

[0205] Correspondingly, the terminal receives the downlink control information from the access network device. The downlink control information is carried on the PDCCH. The downlink control information is used to schedule the data transmission on the first CC. The first indication information in the downlink control information is used to indicate that the first RRM measurement is allowed to be skipped. Step 1701 can refer to step 1601.

[0206] 1702. The terminal skips the first RRM measurement on the first CC based on the downlink control information when the third condition is satisfied, and skips the second RRM measurement on the third CC when at least the first condition is satisfied; or performs the first RRM measurement on the first CC when the third condition is not satisfied.

[0207] The third condition includes any of the following: the time period that the data transmission on the first CC scheduled by the downlink control information needs to occupy overlaps with the time period where the first RRM measurement is located in the time domain, i.e., the time domain resource allocated by the downlink control information for scheduling the data transmission on the first CC includes the time period where the first RRM measurement is located or a part of the time period where the first RRM measurement is located, and the interval between the start time of the time period where the first RRM measurement is located and the end time of the time period that the data transmission on the first CC scheduled by the downlink control information needs to occupy is less than or equal to a second threshold. The first threshold can be set according to actual needs, which is not limited here. For example, the first threshold is 100 us, 200 us, 500 us, 1 ms, 2 ms, etc. For ease of description, the third condition is described below as an example that the time period that the data transmission on the first CC scheduled by the downlink control information needs to occupy overlaps with the time period where the first RRM measurement is located in the time domain.

[0208] The first condition includes any of the following: the time period where the second RRM measurement is located overlaps with the time period where the first RRM measurement is located in the time domain, and the interval between the start time of the time period where the second RRM measurement is located and the end time of the time period where the first RRM measurement is located is less than or equal to the first threshold. The above first condition is for the RRM measurement on the third CC. The terminal can determine whether to skip the RRM measurement to be performed on each CC in a similar or same manner. As an example, if the above first condition further includes: the time period where the third RRM measurement on the fourth CC is located overlaps with the time period where the first RRM measurement is located in the time domain, or the interval between the start time of the time period where the third RRM measurement is located and the end time of the time period where the first RRM measurement is located is less than or equal to the first threshold; the terminal also skips the third RRM measurement on the fourth CC based on the downlink control information. In a possible design, when the terminal has a certain RRM measurement to be performed on any CC that meets a target condition, the terminal also skips the RRM measurement on the arbitrary CC based on the downlink control information; wherein the target condition is that the time period where the RRM measurement is located overlaps with the time period where the first RRM measurement is located in the time domain, or the interval between the start time of the time period where the RRM measurement is located and the end time of the time period where the first RRM measurement is located is less than or equal to the first threshold. As an example, after the terminal receives the downlink control information, it determines the RRM measurement to be performed on each CC that meets the target condition, respectively; then, the first RRM measurement on the first CC is skipped, and the RRM measurement to be performed on each CC that meets the target condition is skipped. Skipping the RRM measurement to be performed on the third CC that meets the target condition can be described as: in the case of at least meeting the first condition, the second RRM measurement on the third CC is skipped, and the first condition and the target condition are the same for the third CC.

[0209] Step 1702 can be replaced by: the terminal performs data transmission on the first CC based on the downlink control information, wherein the time period in which the first RRM measurement is located is available for data transmission on the first CC; in the case where the third condition is met, the terminal skips the first RRM measurement on the first CC and also skips the second RRM measurement on the third CC at least in the case where the first condition is met, the time period in which the terminal performs data transmission on the first CC includes the time period in which the first RRM measurement is located or a part of the time period in which the first RRM measurement is located; in the case where the third condition is not met, the terminal performs the first RRM measurement on the first CC.

[0210] Multiplexing Figure 11A, DCI (i.e. downlink control information) is carried on the first CC, the solid rectangular box represents the time period that needs to be occupied by the data transmission on the first CC scheduled by the downlink control information, the dashed rectangular box represents the time period in which the periodic RRM measurement on the first CC is located, the rectangular box pointed to by 111A represents the time period in which the above-mentioned first RRM measurement is located, there is an overlap between the time period that needs to be occupied by the data transmission on the first CC scheduled by the downlink control information and the time period in which the first RRM measurement is located, i.e. the third condition is met, the terminal skips the first RRM measurement, and the time period in which the terminal performs data transmission on the first CC is the time period that needs to be occupied by the data transmission on the first CC scheduled by the downlink control information. In the schematic diagram shown in Figure 11A, the terminal skips the first RRM measurement, and the RRM measurement on the first CC by the terminal does not cause scheduling restriction to the data transmission on the first CC by the terminal, i.e. the data transmission on the first CC by the terminal is not affected by the RRM measurement.

[0211] Multiplexing Figure 11B, DCI (i.e. downlink control information) is carried on the second CC, the solid rectangular box represents the time period that needs to be occupied by the data transmission on the first CC scheduled by the downlink control information, the dashed rectangular box represents the time period in which the periodic RRM measurement on the first CC is located, the rectangular box pointed to by 111B represents the time period in which the above-mentioned first RRM measurement is located, there is no overlap between the time period that needs to be occupied by the data transmission on the first CC scheduled by the downlink control information and the time period in which the first RRM measurement is located, i.e. the third condition is not met, the terminal does not skip the first RRM measurement, and the time period in which the terminal performs data transmission on the first CC is the time period that needs to be occupied by the data transmission on the first CC scheduled by the downlink control information, the time period in which the terminal performs data transmission on the first CC does not include any part of the time period in which the first RRM measurement is located. In the schematic diagram shown in Figure 11B, the terminal does not skip the first RRM measurement, and the terminal performs the first RRM measurement, which does not cause scheduling restriction to the data transmission on the first CC by the terminal.

[0212] In the embodiments of the present application, the terminal skips the first RRM measurement on the first CC based on the downlink control information, and skips the second RRM measurement on the third CC at least when the first condition is met, thereby reducing the scheduling restriction of the data transmission on the first CC caused by the RRM measurement on the first CC, and saving signaling overhead; or performs the first RRM measurement on the first CC when the third condition is not met, thereby reducing the influence of the RRM measurement skipping on the measurement performance.

[0213] FIG. 18 is a flow diagram of another communication method provided by the embodiments of the present application. In the communication method of FIG. 18, one DCI schedules the data transmission of multiple cells, and in the foregoing communication method, the DCI schedules the data transmission on one CC. As shown in FIG. 18, the method includes:

[0214] 1801. The access network device sends downlink control information to the terminal.

[0215] Correspondingly, the terminal receives the downlink control information from the access network device. The downlink control information is carried in the PDCCH. The downlink control information is used to schedule the data transmission on multiple cells. For example, the downlink control information can be DCI format 0_3 / 1_3, and the scheduled cells indicator field in the downlink control information indicates which cells the terminal should schedule the uplink transmission on. The second indication information in the downlink control information is used to indicate skipping the fourth RRM measurement on the multiple cells. For example, the second indication information in the downlink control information is used to indicate skipping the fourth RRM measurement on each of the multiple cells. Illustratively, one cell corresponds to one frequency point, and the terminal can perform RRM measurement on the cell at the frequency point corresponding to the cell. The time period of the fourth RRM measurement of the terminal on a certain cell (any cell) is the first time period for RRM measurement after the last symbol of the PDCCH is offset by the second time offset in the periodic time period for RRM measurement on the cell. Or, the fourth RRM measurement of the terminal on a certain cell is the first RRM measurement after the time offset between the start time and the last symbol of the PDCCH is greater than or equal to the second time offset in the periodic RRM measurement on the cell. Or, the fourth RRM measurement of the terminal on a certain cell is the first RRM measurement after the time offset between the last symbol of the PDCCH and the last symbol of the PDCCH is greater than or equal to the second time offset in the periodic RRM measurement on the cell. Optionally, the communication method of FIG. 18 can further include the steps 1201 to 1203 in FIG. 12 or the steps 1301 to 1303 in FIG. 13.

[0216] The second time offset is related to the SCS of the carrier used by the terminal to perform the RRM measurement on the above-mentioned multiple cells. The second time offset can be the maximum of multiple time offsets, each of which corresponds to a carrier used by the terminal to perform the RRM measurement on the above-mentioned multiple cells. As an example, the downlink control information is used to schedule data transmission on cell #1, cell #2, and cell #3, the carrier used by the terminal to perform the RRM measurement on cell #1 corresponds to time offset #1, the carrier used by the terminal to perform the RRM measurement on cell #2 corresponds to time offset #2, the carrier used by the terminal to perform the RRM measurement on cell #3 corresponds to time offset #3, and the second time offset is the maximum of time offset #1, time offset #2, and time offset #3.

[0217] In a possible design, the second indication information is 1 bit, when the value of the second indication information is 1, it indicates skipping the fourth RRM measurement on the multiple cells; and when the value of the second indication information is 0, it indicates not skipping the fourth RRM measurement on the multiple cells. In another possible design, the second indication information is 1 bit, when the value of the second indication information is 0, it indicates skipping the fourth RRM measurement on the multiple cells; and when the value of the second indication information is 1, it indicates not skipping the fourth RRM measurement on the multiple cells.

[0218] 1802. The terminal skips the fourth RRM measurement on the above-mentioned multiple cells based on the downlink control information, and the time period in which the fourth RRM measurement is performed by the terminal on a cell is the first time period for RRM measurement after the last symbol of the PDCCH is offset by the second time offset in the time period for periodic RRM measurement on the cell.

[0219] In other words, the terminal performs data transmission on the above-mentioned multiple cells based on the downlink control information, wherein the time period in which the fourth RRM measurement is performed on any cell is available for data transmission on the cell, and the terminal can perform data transmission on the cell in the time period in which the fourth RRM measurement is performed on the cell. In other words, the terminal performs data transmission on the above-mentioned multiple cells based on the downlink control information, wherein the time period in which the terminal performs data transmission on any cell can include the time period in which the fourth RRM measurement is performed on the cell or a part of the time period in which the fourth RRM measurement is performed on the cell, or can not include any part of the time period in which the fourth RRM measurement is performed on the cell. The terminal skips the fourth RRM measurement on any cell can mean that the terminal does not perform RRM measurement on the cell in the time period in which the fourth RRM measurement is performed on the cell.

[0220] In the embodiments of the present application, the terminal skips the fourth RRM measurement on multiple cells based on the downlink control information, so that the RRM measurement of the terminal on the multiple cells does not cause scheduling restriction on data transmission of the terminal on the multiple cells, and the time delay of data transmission can be reduced.

[0221] FIG. 19 is a flow diagram of another communication method provided by the embodiments of the present application. The communication method of FIG. 19 is different from the communication method of FIG. 18 in that the second indication information in the downlink control information has different functions. In the communication method of FIG. 19, the second indication information in the downlink control information is used to indicate that the terminal is allowed to skip the fourth RRM measurement on multiple cells. As shown in FIG. 19, the method includes the following steps.

[0222] 1901. The access network device sends downlink control information to the terminal.

[0223] Correspondingly, the terminal receives the downlink control information from the access network device. The downlink control information is carried in the PDCCH. The downlink control information is used to schedule data transmission on multiple cells. For example, the downlink control information can be DCI format 0_3 / 1_3, and the scheduled cells indicator field in the downlink control information indicates on which cells the terminal should schedule uplink transmission. The second indication information in the downlink control information is used to indicate that the terminal is allowed to skip the fourth RRM measurement on the multiple cells. For example, one cell corresponds to one frequency point, and the terminal can perform RRM measurement on the cell at the frequency point corresponding to the cell. The time period for the fourth RRM measurement of the terminal on any cell is the first time period for RRM measurement after the last symbol of the PDCCH is offset by the second time offset in the periodic time period for RRM measurement on the cell. Optionally, the communication method of FIG. 19 can further include the steps 1201 to 1203 in FIG. 12 or the steps 1301 to 1303 in FIG. 13.

[0224] The second time offset is related to the SCS of the carrier used by the terminal to perform RRM measurement on the multiple cells. The second time offset can be the maximum value of multiple time offsets, and the multiple time offsets are respectively corresponding to the carriers used by the terminal to perform RRM measurement on the multiple cells. As an example, the downlink control information is used to schedule data transmission on cell #1, cell #2 and cell #3, the carrier used by the terminal to perform RRM measurement on cell #1 corresponds to time offset #1, the carrier used by the terminal to perform RRM measurement on cell #2 corresponds to time offset #2, the carrier used by the terminal to perform RRM measurement on cell #3 corresponds to time offset #3, and the second time offset is the maximum value of time offset #1, time offset #2 and time offset #3.

[0225] In a possible design, the second indication information is 1 bit, and when the value of the second indication information is 1, it indicates that the fourth RRM measurement on the plurality of cells is allowed to be skipped; and when the value of the second indication information is 0, it indicates that the fourth RRM measurement on the plurality of cells is not allowed to be skipped. In another possible design, the second indication information is 1 bit, and when the value of the second indication information is 0, it indicates that the fourth RRM measurement on the plurality of cells is allowed to be skipped; and when the value of the second indication information is 1, it indicates that the fourth RRM measurement on the plurality of cells is not allowed to be skipped.

[0226] 1902. The terminal skips the fourth RRM measurement on one or more first cells based on the downlink control information, the fourth RRM measurement on the first cells satisfying a fourth condition; or performs the fourth RRM measurement on one or more second cells, the fourth RRM measurement on the second cells not satisfying the fourth condition.

[0227] The one or more first cells are included in the plurality of cells scheduled by the downlink control information. The one or more second cells are included in the plurality of cells scheduled by the downlink control information. The fourth condition includes any of the following: a time period in which the fourth RRM measurement on a cell overlaps, in a time domain, a time period in which data transmission on the cell scheduled by the downlink control information needs to occupy; and a time interval between a start time of the time period in which the fourth RRM measurement on the cell is performed and an end time of the time period in which the data transmission on the cell scheduled by the downlink control information needs to occupy is less than or equal to a third threshold. The third threshold can be set according to actual needs, which are not limited herein. For example, the third threshold is 100 us, 200 us, 500 us, 1 ms, 2 ms, etc.

[0228] In embodiments of this application, the terminal skips the fourth RRM measurement on one or more first cells based on the downlink control information, the fourth RRM measurement on the first cells satisfying a fourth condition, thereby reducing the scheduling restriction on data transmission on the cell caused by the RRM measurement of the terminal on the cell; or performs the fourth RRM measurement on one or more second cells, the fourth RRM measurement on the second cells not satisfying the fourth condition, thereby reducing the influence of the RRM measurement skipping on the measurement performance.
