Description

Communication method and apparatus for RRM measurement

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on February 7, 2024, with application number 202410175836.9 and invention name “Communication Method and Device for RRM Measurement”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and more particularly, to a communication method and apparatus for RRM measurement. Background Art

[0003] With the continuous development of the fifth-generation (5G) communication system, data transmission latency continues to decrease and transmission capacity is increasing. 5G communication systems are gradually infiltrating some multimedia services with strong real-time requirements and large data capacity requirements, such as video transmission, cloud gaming (CG), and extended reality (XR). XR includes virtual reality (VR) and augmented reality (AR).

[0004] For example, the 3rd Generation Partnership Project (3GPP) proposed a measurement gap (MG) method, which reserves a portion of time (MG time) for the terminal device to tune the receiver to the target cell frequency for signal measurement. During this time, the UE cannot send or receive data. Similarly, during the radio resource management (RRM) measurement process, there are scheduling restrictions caused by MG or other measurement configurations, which prevent the terminal device from sending or receiving data. Therefore, it is impossible to take into account both RRM measurement performance and service transmission performance. Summary of the Invention

[0005] The present application provides a communication method and a communication device, which achieve flexible configuration by indicating the time of RRM measurement, while improving the reliability of service transmission and taking into account the performance of RRM measurement.

[0006] In a first aspect, a communication method is provided. This method can be applied to a terminal, such as a terminal or a communication module in a terminal, or a circuit or chip in the terminal responsible for communication functions (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). The following describes this method using the application of a terminal as an example.

[0007] In this method, a terminal device sends or receives first information, the first information includes first duration information, the first duration information indicates a first time period, the first time period is included in a second time period, and the first information is carried in a media access control control element (MAC CE); radio resource management RRM measurement is skipped in the first time period, and RRM measurement is performed on at least a part of the time period of the second time period except the first time period, or RRM measurement is performed on at least a part of the time period of the first time period, and RRM measurement is skipped on the time period of the second time period except the first time period.

[0008] By adopting the above method, the terminal device can inform the network device through MAC CE or the network device can instruct the first time period, and by skipping RRM measurement or performing RRM measurement within the first time period, the RRM measurement time can be flexibly configured according to requirements such as data transmission or channel measurement, so as to reduce the time domain conflict caused by the scheduling restriction of RRM measurement, while improving the reliability of service transmission and taking into account the RRM measurement performance.

[0009] In the present application, skipping RRM measurement in the first time period and performing RRM measurement in at least a part of the second time period except the first time period can be understood as: deactivating RRM measurement in the first time period, activating RRM measurement in the second time period except the first time period, and the terminal device can perform measurement as needed in the time period when RRM measurement is activated, that is, performing RRM measurement in at least a part of the second time period except the first time period, or not. At this time, the first information is used to deactivate the first time period in the RRM measurement configuration.

[0010] Performing RRM measurements on at least a portion of the first time period and skipping RRM measurements on the second time period other than the first time period can be understood as: activating RRM measurements on the first time period and deactivating RRM measurements on the second time period other than the first time period. The terminal device may perform measurements as needed on the time period when the RRM measurement is activated, that is, perform RRM measurements on at least a portion of the first time period, or may not perform measurements. At this time, the first information is used to activate the first time period in the RRM measurement configuration.

[0011] In one possible design, when RRM measurements are performed on at least a portion of a first time period and RRM measurements are skipped on a second time period other than the first time period, the method further includes: stopping RRM measurements in a third time period, wherein the third time period and the second time period belong to different RRM measurement configurations.

[0012] In the present application, stopping the RRM measurement in the third time period, performing RRM measurement on at least a portion of the time period in the first time period, and skipping the RRM measurement on the time period other than the first time period in the second time period can be understood as: switching the measurement configuration. Switching from the RRM measurement configuration corresponding to the third time period to the RRM measurement configuration corresponding to the second time period, so that RRM measurement is not performed in the RRM measurement configuration corresponding to the third time period, but RRM measurement is performed in the RRM measurement configuration corresponding to the second time period, that is, RRM measurement is performed on at least a portion of the time period in the first time period belonging to the second time period, and RRM measurement is skipped in the remaining time periods.

[0013] By adopting the above method, the terminal device can switch between multiple sets of RRM measurement configurations as needed, and the configuration is more flexible, thereby ensuring the reliability of the terminal device's communication. For example, when the signal quality of the service cell of the terminal device is good, it means that there is no need to frequently switch cells, and there is no need to frequently perform RRM measurements. Therefore, the terminal device can switch the RRM measurement configuration, such as increasing the interval of the RRM measurement period or reducing the duration of the RRM measurement period, thereby reducing the scheduling limit of the RRM measurement, ensuring the transmission capacity of the service data, improving the service transmission performance, and enhancing the user experience. For another example, when the signal quality of the service cell of the terminal device decreases, it means that frequent cell switching is required, and frequent RRM measurements are required. Therefore, the terminal device can switch the RRM measurement configuration, such as reducing the interval of the RRM measurement period or increasing the duration of the RRM measurement period, to improve the RRM measurement performance and enhance the user experience.

[0014] In the present application, a terminal device may be configured with multiple sets of RRM measurement configurations, such as multiple MG configurations or multiple radio resource management measurement time configurations (SMTCs). The third period and the second period belonging to different RRM measurement configurations may be understood as follows: the second period is a measurement period in one RRM measurement configuration, and the third period is a measurement period in another RRM measurement configuration. The second and third periods may have different durations or intervals.

[0015] In one possible design, the first duration information indicates M first time periods, and the M first time periods are respectively included in M ​​second time periods, where M is a positive integer.

[0016] With the above method, the first duration information indicates the first time period in multiple RRM measurement gaps, and the time for performing or not performing RRM measurement in each second time period is flexibly adjusted. The configuration method is more flexible and the communication reliability is improved.

[0017] In a possible implementation, the first duration information may indicate a first time period, and M may be preconfigured, so that the first duration information may indicate M first time periods within M consecutive second time periods.

[0018] In another possible implementation, the first duration information may include information of M first time periods, and the M first time periods may be the same or different, so that the first duration information can support M first time periods corresponding to M consecutive second time periods.

[0019] In one possible design, the first information also includes quantity information, the quantity information indicates a quantity M, the quantity information and the first duration information indicate M first time periods, the M first time periods are respectively included in M ​​second time periods, and M is a positive integer.

[0020] Using the above method, the first information also includes information indicating M, so that not only the time for performing or not performing RRM measurement in each second time period can be adjusted, but also the number of second time periods that need to be adjusted can be configured. The configuration method is more flexible and improves communication flexibility and reliability.

[0021] In one possible design, the first information also includes bitmap information, and the bitmap information and the first duration information indicate M first time periods, and the M first time periods are respectively included in M ​​second time periods, where M is a positive integer.

[0022] Using the above method, the bitmap information can indicate the positions of the M first time periods, and thus, combined with the first time period indicated by the first duration information, it is possible to determine the M first time periods in which RRM measurements need to be performed or not. The M second time periods can be discontinuous, and the configuration method is flexible, which improves communication flexibility and reliability.

[0023] In one possible implementation, the bitmap information is a bitmap including multiple bits, each bit corresponding to a second time period. For example, a bit "1" indicates that the first time period is included in the second time period, and a bit "0" indicates that the first time period is not included in the second time period; alternatively, a bit "1" indicates that the first time period is not included in the second time period, and a bit "0" indicates that the first time period is included in the second time period. Thus, M "1s" in the bitmap can indicate M first time periods, or M "0s" in the bitmap can indicate M first time periods. The M second time periods corresponding to the M first time periods can be discontinuous in the time domain.

[0024] In one possible design, the first duration information indicates the duration of the first time period.

[0025] In one possible design, the first duration information indicates the duration from the first time unit after the last symbol of the physical uplink shared channel (PUSCH) or physical downlink shared channel (PDSCH) carrying the MAC CE to the end of the first time period.

[0026] In one possible design, the RRM measurement includes measurement of at least one of the following: a synchronization signal block (SSB); and a channel state information reference signal (CSI-RS).

[0027] Based on the above solution, the terminal device can promptly indicate the time period when RRM measurement is required or not, thereby improving the transmission performance of service data while taking into account the signal measurement performance, improving the user experience and being more flexible.

This method can be applied to the network side, such as an access network device, a module (such as a circuit, chip, or chip system) in the access network device, or a logical node, logic module, or software that implements all or part of the access network device's functions.

[0077] The technical solution in this application will be described below with reference to the accompanying drawings.

[0078] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as: LTE system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD), fifth generation (5G) system or new radio (NR) and other evolved communication systems, vehicle-to-X (V2X), where V2X may include vehicle to network (V2N), vehicle to vehicle (V2V), vehicle to infrastructure (V2I), vehicle to pedestrian (V2P), etc., long-term evolution of vehicle communication (LTE-V), Internet of Vehicles, machine type communication (MTC), Internet of Things (IoT), long-term evolution of machine communication (LTE-M), machine to machine (M2M), device to device (D2D), etc.

[0079] FIG1 is a schematic diagram of a possible, non-limiting system suitable for embodiments of the present application.

[0080] As shown in Figure 1 , the communication system 10 includes a radio access network (RAN) 100 and a core network (CN) 200. 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). RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment (not shown in Figure 1 ). Terminal 120 is wirelessly connected to RAN node 110. RAN node 110 is wirelessly or wiredly connected to CN 200. The core network equipment in CN 200 and RAN node 110 in RAN 100 may be separate physical devices, or they may be a single physical device that integrates core network logical functions and radio access network logical functions.

[0081] The RAN 100 may be a cellular system related to the Third Generation Partnership Project (3GPP), such as a fourth generation (4G) mobile communication system, a fifth generation (5G) mobile communication system, or a future-oriented evolution system (e.g., a sixth generation (6G) mobile communication system). The RAN 100 may also be an open access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (WiFi) system. The RAN 100 may also be a communication system that integrates two or more of the above systems.

[0082] RAN nodes 110, sometimes also referred to as access network equipment, RAN entities, or access nodes, form part of a communication system and facilitate wireless access for terminals. Multiple RAN nodes 110 in the communication system can be of the same type or different types. In some scenarios, the roles of RAN nodes 110 and terminals 120 are relative. For example, network element 120i in Figure 1 can be a helicopter or drone, which can be configured as a mobile base station. For terminals 120j accessing the RAN 100 via network element 120i, network element 120i is a base station; however, for base station 110a, network element 120i is a terminal. RAN nodes 110 and terminals 120 are sometimes referred to as communication devices. For example, network elements 110a and 110b in Figure 1 can be understood as communication devices with base station functionality, and network elements 120a-120j can be understood as communication devices with terminal functionality.

[0083] In one possible scenario, a RAN node may be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a next generation base station in a sixth generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. A RAN node may be a macro base station (such as 110a in FIG1 ), a micro base station or an indoor station (such as 110b in FIG1 ), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, a RAN node may also be a server, a wearable device, a vehicle or an onboard device. For example, an access network device in vehicle to everything (V2X) technology may be a road side unit (RSU). All or part of the functions of the RAN node in this application may 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 may also be provided with a communication module, circuit, or chip that performs the corresponding communication functions. The RAN node may also be configured with program instructions for performing the corresponding communication functions and corresponding program instructions. The RAN node in this application may also be a logical node, logical module, or software that can implement all or part of the RAN node functions.

[0084] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, and different RAN nodes respectively implement part of the functions of the base station. For example, the RAN node can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set separately, or they 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 radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0085] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (Open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of 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.

[0086] Terminal 120 can be a device or module that accesses the aforementioned communication system and has corresponding communication functions. A terminal can also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), the Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, etc. A terminal can be a mobile phone, tablet computer, computer with wireless transceiver functions, wearable device, vehicle, drone, helicopter, airplane, ship, robot, robotic arm, smart home appliance, transport vehicle with wireless communication functions, communication module, etc. The embodiments of this application do not limit the device form of the terminal. The terminal is typically provided with a communication module, circuit, or chip that performs the corresponding communication functions. The terminal is also configured with program instructions for performing the corresponding communication functions.

[0087] The RAN 100 and terminal 120 can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; they can also be deployed in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the scenarios in which the RAN 100 and terminal 120 are located.

[0088] CN 200 can be a 6G core network, a 5G core network, or an evolved 5G core network. Taking the 5G core network as an example, CN 200 includes the access and mobility management function (AMF) network element responsible for services such as mobility management and access management, the session management function (SMF) network element responsible for session management, the user plane function (UPF) network element responsible for data packet routing and forwarding and quality of service (QoS) control on the user plane, and the policy control function (PCF) network element. The above core network elements can work independently or be combined to implement certain control functions. For example, the AMF, SMF, and PCF can be combined together to form a core network device.

[0089] The RAN node can also be expressed in different ways, such as base station or network equipment. Unless otherwise specified in this application, the network equipment is used to express it, where the network equipment is the original expression for the access network equipment (such as base station).

[0090] It should be understood that the above naming is defined only to facilitate the distinction between different functions and should not constitute any limitation to this application. This application does not exclude the possibility of adopting other naming in 5G networks and other future networks. For example, in a 6G network, some or all of the above network elements may continue to use the terminology used in 5G, or may adopt other names.

[0091] It should be understood that Figure 1 is merely an example and does not limit the scope of protection of this application. The communication method provided in the embodiments of this application may also involve network elements not shown in Figure 1. Of course, the communication method provided in the embodiments of this application may also include only some of the network elements shown in Figure 1. In addition, the embodiments of this application do not limit the number of terminal devices and network devices included in the communication system.

[0092] In an embodiment of the present application, a terminal device or a network device includes a hardware layer, an operating system layer running on the hardware layer, and an application layer running on the operating system layer. The hardware layer includes hardware such as a central processing unit (CPU), a memory management unit (MMU), and memory (also called main memory). The operating system can be any one or more computer operating systems that implement business processing through processes, such as a Linux operating system, a Unix operating system, an Android operating system, an iOS operating system, or a Windows operating system.

[0093] In addition, various aspects or features of the present application can be implemented as methods, apparatuses, or articles of manufacture using standard programming and / or engineering techniques. The term "article of manufacture" as used in this application covers computer programs that can be accessed from any computer-readable device, carrier, or medium. For example, computer-readable storage media may include, but are not limited to: magnetic storage devices (e.g., hard disks, floppy disks, or magnetic tapes, etc.), optical disks (e.g., compact discs (CDs), digital versatile discs (DVDs), etc.), smart cards, and flash memory devices (e.g., erasable programmable read-only memories (EPROMs), cards, sticks, or key drives, etc.).

[0094] With the rapid increase in communication transmission rates, real-time video transmission has gradually become one of the core services in current networks. The continuous advancement and improvement of extended reality technology has also led to the rapid development of related industries. Virtual reality (VR), a type of extended reality (XR), has entered various fields closely related to people's production and daily lives, including education, entertainment, military, healthcare, environmental protection, transportation, and public health. Compared with traditional video services, VR offers advantages such as multi-perspective and strong interactivity, providing users with a brand new visual experience. Cloud virtual reality (cloud VR) and augmented reality (cloud AR) introduce the concepts and technologies of cloud computing and cloud rendering into VR / AR service applications. Leveraging high-speed and stable networks, cloud-based display and audio output are encoded and compressed and transmitted to user devices, enabling VR / AR service content and rendering to be transferred to the cloud. VR / AR terminal devices can also meet the requirements of lightweight and mobile operation. VR / AR terminal devices connect to the network through network devices or other access points to access VR / AR services from the cloud.

[0095] To enhance the user experience of interacting with the virtual world, XR services have strict bandwidth and latency requirements. During downlink transmission, the server's encoder generates data at a fixed frequency (e.g., 60Hz or 120Hz) and transmits it to the terminal device via the core network and RAN. During uplink transmission, the terminal device uses its built-in camera to capture and continuously upload images of the current scene to the server at a specific frequency (e.g., 60Hz or 120Hz). For example, XR services typically generate data periodically at a specific frame rate. The service models for downlink XR services are generally: AR / VR and cloud gaming. AR / VR frame rates can be 60 frames per second (FPS), generating 60 frames per second, with one frame appearing approximately every 16.67ms. AR / VR frame rates can also be 120 FPS, generating 120 frames per second, with one frame appearing approximately every 8.33ms. Cloud gaming frame rates can be 60 FPS or 120 FPS, generating 60 or 120 frames per second, respectively.

[0096] During the measurement period, the terminal device and the network device prioritize sending and receiving measurement signals, and only send and receive a small amount of data signals. Therefore, the data transmission rate during the measurement period is very low, and users of XR devices will perceive a significant delay in data transmission.

[0097] Exemplarily, the measurement includes intra-frequency measurement and inter-frequency measurement. Intra-frequency measurement means that the cell where the terminal device is currently located and the target cell to be measured are on the same carrier frequency (center frequency). For example, the terminal device can perform measurement through the reference signal inserted during data transmission without affecting the transmission and reception of data. Inter-frequency measurement means that the cell where the terminal device is currently located and the target cell are not on the same carrier frequency. For example, two RF receivers are installed in the terminal device to measure the frequency of the cell and the frequency of the target cell respectively, but this will bring about the problem of increased cost and mutual interference between different frequencies.

[0098] In one implementation, terminal device handover is performed based on terminal measurements of synchronization signals and physical broadcast channel blocks (PBCH blocks, SSBs). The terminal device achieves time and frequency synchronization and obtains necessary system information by receiving and decoding SSBs. To obtain the most accurate SSB measurement results possible, it is necessary to measure all SSBs in the cell as much as possible. Furthermore, SSBs are not transmitted at all time sequences within a scanning cycle. If the terminal device searches for and measures SSBs at all time sequences, significant power waste will result. To effectively indicate the time window for terminal devices to measure SSBs and reduce unnecessary measurement power consumption by terminal devices, SSB-based radio resource management measurement timing configuration (SMTC) is introduced. SMTC is a time window configured by the network device for terminal devices to measure SSBs. Within this time window, the terminal device can perform inter-cell SSB measurements, such as reference signal received power (RSRP) and / or reference signal received quality (RSRQ), without conflicting with normal uplink data transmission.

[0099] Exemplarily, SMTC represents the timing configuration sent by the network device to the terminal through the radio resource control (RRC) message when the terminal device performs SSB-based measurement on a certain cell, including: SMTC period, SMTC offset and SMTC duration. The protocol defines that the configuration of SMTC is a frequency-level configuration, including SMTC1 configuration and SMTC2 configuration, and SMTC2 configuration is an optional configuration. Among them, the SMTC1 configuration contains two sub-elements periodicityAndOffset (periodicity, representing the repetition period of the measurement action; Offset, representing the starting subframe of the measurement action within the period) and duration (representing the duration of the measurement action after the measurement action starts). The SMTC period can be 5ms, 10ms, 20ms, 40ms, 80ms, or 160ms. The value of the SMTC offset is based on a granularity of 1ms and ranges from 0 to the SMTC period minus 1ms. The SMTC duration is set in 1ms granularity and can be 1ms, 2ms, 3ms, 4ms, or 5ms. For example, when the SMTC period is 5ms, the SMTC offset can be 0ms, 1ms, 2ms, 3ms, or 4ms, and the SMTC duration can be 1ms, 2ms, 3ms, 4ms, or 5ms. SMTC2 configuration is optional and is used to flexibly configure differentiated SMTC periods for specified neighboring cells. By configuring a list of available SMTC periods on a frequency band with SMTC2, network equipment can inform terminal devices which SMTC period each neighboring cell on that frequency band should use. If a cell does not explicitly indicate its SMTC period, it should use the longer SMTC period. SMTC2 is optional. Not configuring SMTC2 is equivalent to all neighboring cells using the SMTC period configured with SMTC1. If SMTC2 is configured, the SMTC period configured using it must be less than the periodicityAndOffset of SMTC1. Since the position of the SSB is related to the synchronization signal, different SMTC configurations must cover the position of the SSB signal. SMTC1 and SMTC2 only differ in their periods.

[0100] FIG2 is a schematic diagram of a radio resource management strategy time configuration SMTC based on SSB.

[0101] As shown in Figure 2, the length of a radio frame corresponding to a system frame number (SFN) can be 10ms. A radio frame can contain 10 radio subframes (SFs), meaning that the length of a radio subframe can be 1ms. SFN is a sequence number starting from 0 that identifies the downlink transmission time interval (TTI). For example, the SFN value can be 4, 5, 6, or 7. The SMTC period is 2 frames, or 20ms. The radio subframes in the shaded area represent the SMTC duration, which is 4ms, the duration for the terminal device to perform SSB measurements. The SMTC offset is 2ms.

[0102] In another implementation, signal measurements can be performed using measurement gaps. This involves reserving a measurement gap (MG) period during which the terminal device does not send or receive any data. Instead, the terminal device tunes its receiver to the target cell's frequency to perform inter-frequency measurements. After the MG period, the terminal device switches back to communicating with the serving cell. The MG period is the period during which the terminal device suspends communication with the serving cell to measure inter-frequency neighboring cells or other cells using different radio access technologies (RATs).

[0103] MG is usually sent by the base station to the terminal device through an RRC message, including: measurement gap repetition period (MGRP), MG offset (gapOffset) and measurement gap length (MGL). Among them, MGRP is the specified gap period, that is, the length of the interval from the start time of the current MG period to the start time of the next MG period. MGRP can be 20ms, 40ms, 80ms or 160ms; the gapoffset is the offset of the gap pattern, which can range from 0 to 159 and can be an integer, with a total of 160 offset values. The offset value points to the starting subframe within the period, and its value range is from 0 to MGRP-1. For example, if the period is 20ms, the offset range is 0 to 19; MGL can be 1.5ms, 3ms, 3.5ms, 4ms, 5.5ms or 6ms.

[0104] The starting position of the MG configuration can meet the following requirements: SF=gapoffset mod 10 (2) T=MGRP / 10 (3)

[0105] Among them, mod is the remainder, The radio frame number SFN where the start time of the MG period is located can satisfy the above formula (1), and the starting SF of the start time of the MG period in the SFN can satisfy the above formula (2).

[0106] The terminal device may notify the network device of the MG pattern supported by the terminal device by reporting information supportedGapPattern to the network device. Common MG patterns may be shown in Table 1. It should be noted that Table 1 is only an example given for ease of understanding and is not limited in this application.

[0107] Table 1. Measurement mode table

[0108] During MG activation, the terminal device does not transmit any other signals or data except for some important signals (for example, signals related to the access process). This means that the MG has a higher priority than data transmission and reception. A terminal device can be configured with multiple MGs. The base station can assign a priority to each MG, represented by the high-level parameter gapPriority-r17. Typically, MGs are configured separately, so it is possible for two MGs to conflict in the time domain, that is, the durations of the two MGs overlap in the time domain. In this case, the terminal device can select the MG with the higher priority for measurement.

[0109] Figure 3 is a schematic diagram of a measurement gap (MG). The length of a radio frame corresponding to an SFN can be 10 ms. A radio frame can contain 10 radio subframes (SF), meaning each radio subframe can be 1 ms long. As shown in Figure 3, the MGRP is 2 frames, or 20 ms. The shaded radio subframes represent the MGL, which is the duration of the terminal device's inter-frequency measurement of the target cell, or 6 ms. The gapOffset is 13 ms.

[0110] FIG4 is a schematic diagram showing a conflict between a measurement gap MG and a service data transmission period.

[0111] In XR services, the XR data arrival period is non-integer. For example, for XR video with a frame rate of 60 frames per second (FPS), the frame arrival period is 1 / 60s, which means 60 video frames are generated per second, with one video frame appearing approximately every 16.67ms. Because the XR service arrival period does not match the MG measurement period, XR service data transmission may conflict with the MG. As shown in Figure 4, for XR video with a frame rate of 60 FPS, when using Mode 0, that is, an MGL of 6ms and an MGRP of 40ms, the transmission of two out of every six frames is affected by the MG, such as frames 4 and 6. In other words, in the time domain, the XR service data transmission conflicts with the MG, significantly reducing XR capacity and making it difficult to ensure the reliability of the XR service.

[0112] In summary, during the data transmission process of the XR service, conflicts may occur with certain measurement configurations in the time domain, and it is impossible to take into account both the performance of RRM measurement and the performance of service transmission at the same time. Among them, some measurement configurations may be scenarios where inter-frequency measurement and same-frequency measurement have MG, or scenarios where inter-frequency measurement and same-frequency measurement are not configured with MG. This application does not limit this. In some other scenarios, the scheduling restrictions caused by the measurement configuration will also affect other communication performance of the terminal device, such as channel measurement.

[0113] Based on the above problems, the present application provides a communication method and a communication device, which can take into account both RRM measurement performance and service transmission performance, thereby improving the flexibility of communication configuration while improving service transmission reliability.

[0114] The communication method and device provided by the present application are further described below in conjunction with the accompanying drawings. It can be understood that the present application uses a network device and a terminal as an example to illustrate the execution subject of the interaction diagram, but the present application does not limit the execution subject of the interaction diagram. For example, the method executed by the network device in the present application can also be implemented by a module in the network device (such as a circuit, a chip or a chip system, etc.), or a logical node, a logical module or software that can implement all or part of the network function; 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 chip in the terminal responsible for the communication function (such as a modem chip (also known as a baseband chip), or a SoC chip containing a modem core, or a SIP chip).

[0115] Figure 5 is a flow chart of a communication method 500 provided in an embodiment of the present application. As shown in Figure 5 , the method includes the following steps.

[0116] Method 1: S511, the network device sends the first information, and the corresponding terminal device receives the first information.

[0117] It should be understood that, in a possible implementation, method 500 may also be implemented by:

[0118] Method 2: S512, the terminal device sends the first information, and the corresponding network device receives the first information.

[0119] It should be understood that in method one, the network device can dynamically send MAC CE signaling to indicate to the terminal device whether it needs to activate / deactivate RRM measurement within the first time period based on the data arrival time, delay budget and real-time channel status. At this time, the network device makes the decision and notifies the terminal device through the first information. In method two, the terminal device can dynamically send MAC CE to request the network device to activate / deactivate RRM measurement within a subsequent period of time based on its own cell signal quality or data packet delay. At this time, the terminal device makes the decision and sends a request to the network device through the first information. Optionally, after the terminal device sends the first information to make a request, the network device can also judge the request in combination with the data arrival time, delay budget and real-time channel status, so that the indication to the terminal device can be the first time period requested in the first information, or a new first time period further determined by the network device.

[0120] The first information includes first duration information, the first duration information indicates a first time period, the first time period is included in the second time period, and the first information is carried in a medium access control-control element MAC CE.

[0121] Exemplarily, the first information may be a newly added MAC CE or a reused existing field.

[0122] S521: Skip RRM measurement in a first time period, and perform RRM measurement in at least a portion of a second time period except the first time period.

[0123] Alternatively, in S522 , RRM measurement is performed during at least a portion of the first time period, and RRM measurement is skipped during the second time period except the first time period.

[0124] When the terminal device is configured or pre-configured with multiple sets of measurement configurations, RRM measurements are performed on at least a part of the first time period, and RRM measurements are skipped on the second time period except the first time period, the method 500 also includes: S530, stopping RRM measurements in the third time period.

[0125] The third period and the second period belong to different RRM measurement configurations.

[0126] In this application, performing RRM measurement can be understood as the terminal device performing RRM measurement, or it can be understood as the communication module of the terminal device or the circuit or chip responsible for the communication function in the terminal (such as a modem chip, or a SoC chip containing a modem core, or a SIP chip) performing operations related to RRM measurement.

[0127] In this application, skipping RRM measurement or stopping RRM measurement can be understood as the terminal device not performing RRM measurement, or it can be understood as the communication module of the terminal device or the circuit or chip responsible for the communication function in the terminal (such as a modem chip, or a SoC chip containing a modem core, or a SIP chip) not performing operations related to RRM measurement. At this time, the terminal device or the unit, module or chip inside the terminal device can perform other operations such as data transmission or channel measurement.

[0128] In the present application, skipping RRM measurement in the first time period and performing RRM measurement in at least a part of the second time period except the first time period can be understood as: deactivating RRM measurement in the first time period, activating RRM measurement in the second time period except the first time period, and the terminal device can perform measurement as needed in the time period when RRM measurement is activated, that is, perform RRM measurement in at least a part of the second time period except the first time period, or not measure. The terminal device skips RRM measurement in the first time period, monitors the physical downlink control channel (PDCCH) in the first time period, and receives and sends corresponding PDSCH, PUSCH and physical uplink control channel (PUCCH). At this time, the first information is used to deactivate the first time period in the RRM measurement configuration.

[0129] Performing RRM measurement on at least a part of the time period in the first time period, and skipping RRM measurement on the time period in the second time period except the first time period can be understood as: activating RRM measurement in the first time period, and deactivating RRM measurement on the time period in the second time period except the first time period. The terminal device can perform measurement as needed in the time period when RRM measurement is activated, that is, perform RRM measurement on at least a part of the time period in the first time period, or may not measure. The terminal device skips RRM measurement on the time period in the second time period except the first time period, and can monitor PDCCH on the time period in the second time period except the first time period, and can receive and send corresponding PDSCH, PUSCH and PUCCH. At this time, the first information is used to activate the first time period in the RRM measurement configuration.

[0130] In the following description, activation and deactivation can refer to the above understanding and will not be repeated.

[0131] The network device can dynamically send MAC CE signaling to indicate whether the terminal device needs to activate / deactivate RRM measurement in the first time period based on the data arrival time, delay budget and real-time channel status, or the terminal device can dynamically send MAC CE to request the network device to activate / deactivate RRM measurement in a subsequent period of time based on its own cell signal quality or data packet delay.

[0132] There are several implementation methods as follows depending on the different starting points of the duration indicated by the first duration information.

[0133] In a possible implementation manner, the first duration information indicates a duration from the first time unit after the last symbol of the PUSCH or PDSCH carrying the MAC CE to the end of the first time period.

[0134] As shown in Figure 6, the terminal device starts from the first time unit after sending a MAC CE or receiving the last symbol of a MAC CE, and activates or deactivates RRM measurement within the length of time indicated by the first duration information (the first time period, i.e., the shaded part in the figure).

[0135] It should be understood that the time unit may be a time slot or a subframe, or may be other time length units.

[0136] The terminal device skips RRM measurement in the first time period and performs RRM measurement in at least a portion of the second time period other than the first time period. That is, the terminal device can perform other services such as data transmission or channel measurement in the shaded time period, and can perform RRM measurement in the other time periods of the second time period other than the shaded time period. For example, the terminal device can monitor the PDCCH in the shaded time period and perform corresponding PDSCH, PUSCH and PUCCH reception and transmission.

[0137] Alternatively, the terminal device performs RRM measurement in at least a portion of the first time period, and skips RRM measurement in the second time period other than the first time period, that is, the terminal device may perform RRM measurement in at least a portion of the time period in the shaded portion, and may perform other services such as data transmission or channel measurement in the second time period other than the shaded portion. For example, the terminal device may monitor PDCCH in the second time period other than the shaded portion, and receive and transmit corresponding PDSCH, PUSCH, and PUCCH.

[0138] In another possible implementation, the first duration information indicates the duration of the first time period.

[0139] In a possible embodiment, as shown in Figure 7, the first RRM measurement period (i.e., the second time period) of the terminal device after sending a MAC CE or receiving the last symbol of a MAC CE may be a configured MG period or an SMTC period, and the RRM measurement is activated or deactivated within the time length indicated by the first duration information.

[0140] Optionally, the first duration information indicates M first time periods, the M first time periods are respectively included in M ​​second time periods, and M is a positive integer.

[0141] In another possible embodiment, as shown in Figure 8, the terminal device activates or deactivates RRM measurement within the time length indicated by the first duration information during the last M RRM measurement periods (i.e., M second time periods) after sending a MAC CE or receiving the last symbol of a MAC CE, which may be a configured MG period or an SMTC period.

[0142] There are also many different implementation methods for the signaling format of the first information.

[0143] For scenarios where the terminal device has only one set of measurement configurations, the MAC CE is used to indicate activation / deactivation of the corresponding measurement configuration.

[0144] The first information may also include an A / D field, which indicates whether to skip RRM measurements or perform RRM measurements during the first period. For example, setting this field to "1" indicates activation, while setting it to "0" indicates deactivation. For another example, setting this field to "0" indicates activation, while setting it to "1" indicates deactivation. This field is 1 bit long.

[0145] The first information may further include a reserved bit, which is set to 0 and reserved for other information.

[0146] In a possible implementation, the first duration information indicates the duration of the first time period.

[0147] For example, as shown in Figure 9, the first duration information includes a field called XR MG Timing, which can occupy K bits and indicates the duration of the first time period, where K is predefined or preconfigured. The duration can be an absolute time (in milliseconds), a number of subframes, or a predefined time table, where K is the index of the corresponding table.

[0148] In a possible embodiment, the first duration information may indicate M first time periods, where the M first time periods are respectively included in M ​​second time periods, and M is a positive integer.

[0149] For example, the first duration information may indicate a duration, and the lengths of the M first time periods are all the duration indicated by the first duration information, where M may be predefined or preconfigured. The M consecutive second time periods correspond to the M first time periods.

[0150] As another example, as shown in FIG10 , the first duration information may indicate M durations, i.e., include M duration information. For example, the first duration information may be a matrix including M durations. The lengths of the M first time periods are respectively the M durations indicated by the first duration information. The M durations may be the same or different. M consecutive second time periods correspond to the M first time periods.

[0151] In another possible embodiment, as shown in FIG11 , the first information further includes quantity information, the quantity information indicates a quantity M, the quantity information and the first duration information indicate M first time periods, the M first time periods are respectively included in M ​​second time periods, and M is a positive integer.

[0152] Exemplarily, a field in the first information, such as a reserved bit, is quantity information M, combined with a duration indicated by the first duration information, so that M first time periods can be obtained, and M consecutive second time periods correspond to the M first time periods.

[0153] It should be understood that the positional relationship of the different information or fields in the figure is only an example and can also be arranged in a different order. For example, the quantity information can be placed before the first duration information, and the A / D field can be placed after the first duration information. This application does not limit the location of the fields.

[0154] In another possible embodiment, the first information further includes bitmap information, and the bitmap information and the first duration information indicate M first time periods, and the M first time periods are respectively included in M ​​second time periods, where M is a positive integer.

[0155] Exemplarily, the first information may include a bitmap, wherein one bit in the bitmap corresponds to a configuration mode of M first time periods. For example, the configuration modes of the M first time periods may be arranged within M consecutive second time periods, or within M intermittent second time periods. This application does not limit the specific configuration modes of the M first time periods. Thus, bit "1" can be used to indicate that the configuration modes of the M first time periods are activated, and bit "0" can be used to indicate that the configuration modes of the M first time periods are deactivated; or, bit "1" can indicate that the configuration mode is deactivated, and bit "0" can be used to indicate that the configuration mode is activated.

[0156] As another example, the bitmap included in the first information may include K bits, and the K bits correspond one-to-one to the K measurement gaps after the first information is sent or received. Thus, a bit "1" may indicate that the corresponding measurement gap includes one of the M first time periods, and a bit "0" may indicate that the corresponding measurement gap does not include one of the M first time periods; alternatively, a bit "1" may indicate that the corresponding measurement gap does not include one of the M first time periods, and a bit "0" may indicate that the corresponding measurement gap includes one of the M first time periods. For example, when the bitmap information is 101, where "1" indicates that the corresponding measurement gap includes one of the M first time periods, and "0" indicates that the corresponding measurement gap includes one of the M first time periods, as shown in FIG12 , the bitmap information and the first duration information indicate two first time periods, which are respectively within the first measurement gap and the third measurement gap after the first information is sent or received. That is, the second time periods are within the first measurement gap and the third measurement gap. In this case, the M second time periods corresponding to the M first time periods may be discontinuous measurement gaps.

[0157] In another possible implementation, the duration of the first time period may be predefined.

[0158] As shown in FIG13 , if the duration of the first time period is not carried in the MAC CE but is predefined, the format of the MAC CE may not include the first duration information.

[0159] For scenarios where multiple measurement configurations are configured or pre-configured, the MAC CE is used to indicate activation / deactivation / switching of the corresponding measurement configurations.

[0160] The format description of the first duration information is the same as that in the scenario where the terminal device has only one set of measurement configurations. Please refer to the previous text and will not be repeated here.

[0161] As shown in Figure 14, the first information may include a field A / D / S, which indicates activation / deactivation / switching within the first time period. For example, if the field is set to 11, it indicates activation, 00 indicates deactivation, and 10 and / or indicates switching. The field length is 2 bits.

[0162] The first information also includes a configuration ID field XR MG ID, a pre-configured measurement GAP identifier maxNrofGapId-r17 is 8, and the field length is 3 bits. This field indicates whether the corresponding configured MG is activated / deactivated, or switched to the corresponding MG configuration.

[0163] The switching in this application may be understood as switching from one set of measurement configurations to another set of measurements.

[0164] When the first information indicates switching, the terminal device first stops RRM measurement in the third time period, then performs RRM measurement in at least a portion of the first time period, and skips RRM measurement in the second time period other than the first time period. The third time period and the second time period belong to different RRM measurement configurations.

[0165] When the RRM measurement in the third time period is switched to the second time period, the first time periods obtained according to the measurement configurations with different durations indicated by the first duration information are different.

[0166] Exemplarily, for a scenario in which MG is configured, when the signal quality of the service cell of the terminal device is good, the terminal device may instruct to switch from MG with a measurement period of 40ms (i.e., RRM measurement within the third time period) to MG with a measurement period of 80ms (i.e., RRM measurement within the second time period); or, when the signal quality of the service cell of the terminal device is poor, the terminal device may instruct to switch from MG with a measurement period of 80ms to MG with a measurement period of 40ms.

[0167] As another example, for a scenario configured with SMTC, when the signal quality of the service cell of the terminal device is good, the terminal can instruct to switch from a measurement configuration with an SMTC2 period of 20 subframes to a measurement configuration with an STMC1 period of 80 subframes; or, when the signal quality of the service cell of the terminal device is poor, it can instruct to switch from a measurement configuration with an SMTC1 period of 80 subframes to a measurement configuration with an STMC2 period of 20 subframes. It should be understood that the measurement gap in the above-mentioned MG scenario and the measurement time slot in the SMTC scenario are both used for signal measurement on the terminal side.

[0168] It should be noted that, in the above example, the measurement configuration corresponding to the third time period changes from an activated state to a deactivated state, and the measurement configuration corresponding to the second time period changes from a deactivated state to an activated state, which can be regarded as a switching of the measurement configuration.

[0169] In another possible implementation, the duration of the first time period may be predefined.

[0170] As shown in FIG15 , if the duration of the first time period is not carried in the MAC CE but is predefined, the format of the MAC CE may not include the first duration information.

[0171] It should be noted that the eLCID of the MAC subheader corresponding to the MAC CE of the activation / deactivation / handover request is different from that of the MAC CE of the activation / deactivation / handover command.

[0172] The communication method embodiment of the present application is described in detail above in conjunction with Figures 1 to 15 . The communication device embodiment of the present application will be described in detail below in conjunction with Figures 16 and 17 . It should be understood that the description of the device embodiment corresponds to the description of the method embodiment. Therefore, for portions not described in detail, reference can be made to the aforementioned method embodiment.

[0173] Figure 16 is a possible exemplary block diagram of a communication device involved in an embodiment of the present application. As shown in Figure 16, the communication device 1000 may include modules or units corresponding to the above-mentioned method embodiments.

As shown in Figure 17(a), the terminal 2000 includes: one or more antennas 2010, a radio frequency processing system 2020, and a processor system 2030.

[0199] In the downlink or sidelink direction, the RF processing system 2020 receives RF signals through the antenna 2010 and sends the processed signals to the processor system 2030 for further processing. In the uplink or sidelink direction, the processor system 2030 processes the terminal side information and sends it to the RF processing system 2020.

It may include one or more components such as an RF switch, a duplexer, a filter, a power amplifier, an antenna tuner, and a low-noise amplifier. RFFE 2021 may be a circuit system composed of multiple discrete components or may be integrated and packaged in one or more chips. RF transceiver 2022 is responsible for processing the RF signal received by the RFFE into a baseband / intermediate frequency (IF) signal for further processing by the processor system 2030, and for processing the baseband / IF signal provided by the processor system 2030 into an RF signal for transmission to RFFE 2021. The baseband / IF signal transmitted between the RF transceiver 2022 and the processor system 2030 may be a digital signal or an analog signal.
