Description

Method and communication apparatus for measurement

[0001] The present application claims priority from the Chinese patent application No. 202411360631.4 filed on September 27, 2024, and entitled "Method and communication apparatus for measurement", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, in particular to a method and communication apparatus for measurement. BACKGROUND

[0003] With the continuous development of the fifth generation (5th generation, 5G) communication system, the data transmission delay is continuously reduced, the transmission capacity is increasingly large, and the communication system gradually penetrates into some multimedia services with strong real-time performance and large data capacity requirements, such as video transmission, cloud gaming (cloud gaming, CG) and extended reality (extended reality, XR) and the like.

[0004] Exemplarily, the third generation partnership project (3rd generation partnership project, 3GPP) proposes a measurement gap (measurement gap, MG) mode, that is, a part of time (MG time) is reserved, and the terminal device adjusts the receiver to the target cell frequency point to perform signal measurement. In addition, in order to effectively instruct the terminal device to measure the synchronization signal block (synchronization signal and PBCH block, SSB), and reduce unnecessary measurement power consumption, the base station can configure a time window for the terminal device to measure the SSB, that is, the SSB-based radio resource management measurement timing configuration (SSB-based radio resource management measurement timing configuration, SMTC). However, in the actual radio resource management (radio resource management, RRM) measurement process, the scheduling restriction caused by MG or SMTC may cause the terminal device to be unable to perform data transmission and reception, and thus the service transmission performance and the measurement performance cannot be considered at the same time. SUMMARY

[0005] The present application provides a communication method and communication apparatus, so as to improve the service transmission reliability while considering the measurement performance.

[0006] In a first aspect, a communication method is provided. The method can be applied to a terminal side, for example, a terminal or a communication module in the terminal, or a circuit or chip (such as a modem chip, also known as a baseband chip, or a system on chip (SoC) chip or a system in package (SIP) chip containing a modem core) responsible for communication functions in the terminal. The method is described by taking the case of being applied to a terminal.

[0007] In the method, first information is received; in a case where at least a first condition is met, RRM measurement of a first system is skipped according to the first information, the RRM measurement being a first RRM measurement after a first time period in the first system, the first time period being after a time domain unit where the first information is located, and the first condition being that a time interval between a starting time of the RRM measurement of the first system and the time domain unit where the first information is located is greater than or equal to the first time period; and RRM measurement of a second system is performed, the first system and the second system being different systems.

[0008] Exemplarily, the implementation manner can be applied to a new radio (NR) system under a standalone networking scenario of a long term evolution (LTE) system with less RRM measurement. It can be understood that the implementation manner is mainly used to restrict RRM measurement of the first system, that is, whether to skip RRM measurement of the first system is determined by judging whether at least the first condition is met, and in comparison, it is not used to restrict RRM measurement of the second system, that is, the terminal determines to perform RRM measurement of the second system.

[0009] That is, the terminal supports the first system and the second system at the same time, and in a case where at least the first condition is met, the terminal skips RRM measurement of the first system according to the first information. For RRM measurement of the second system, the terminal will perform or not skip. In other words, as long as there is RRM measurement of the second system, the terminal will perform the RRM measurement of the second system to improve the RRM measurement performance of the second system. That is, by performing or not skipping RRM measurement of the second system, the RRM measurement performance of the second system can be improved. At the same time, reducing RRM measurement behavior of the first system can realize scheduling restriction caused by service data transmission and improve service data transmission performance.

[0010] With the above method, the terminal side skips the RRM measurement of the first system according to the first information in a case that a time interval between a starting moment of the RRM measurement of the first system and a time domain unit where the first information is located is greater than or equal to the first time period, that is, at least the first condition is met. In other words, the terminal performs the RRM measurement of the first system in a case that it is determined that the first condition is not met or at least the second condition is met. In addition, the terminal performs or does not skip the RRM measurement of the second system for the RRM measurement of the second system supported by the terminal. This implementation manner can reduce the scheduling restriction of service data caused by the RRM measurement of the first system, reduce the conflict between the service data transmission and the RRM measurement, improve the service data transmission reliability, and meanwhile, can take into account the measurement performance. In particular, in the inter-system scenario, the terminal skips the RRM measurement of the first system in a case that at least the first condition is met, which can improve the transmission performance of the service data and improve the overall service experience of the terminal. Meanwhile, since the terminal performs or does not skip the RRM measurement of the second system, the RRM measurement performance of the second system can be improved.

[0011] In a possible design, the method further includes: performing the RRM measurement of the first system in a case that at least the second condition is met. The second condition is that a time interval between a starting moment of the RRM measurement of the first system and a time domain unit where the first information is located is less than the first time period.

[0012] With the above method, in a case that the terminal side determines that the time interval between the starting moment of the RRM measurement of the first system and the time domain unit where the first information is located is less than the first time period, it indicates that the time interval between the first information and the RRM measurement of the first system is small, for example, the terminal can not skip the RRM measurement of the first system in time, and therefore, the terminal can determine to perform the RRM measurement of the first system, which can improve the RRM measurement performance of the first system.

[0013] In a possible design, the method further includes: receiving second information, the second information indicating a time length of the first time period.

[0014] In a possible design, the time length of the first time period can be predefined or preconfigured. The predefinition can include predefinition, for example, protocol definition, and the preconfiguration can be implemented by pre-saving corresponding codes, tables, functions, texts, strings or other information indicating manners on the terminal side and / or the network side, and the application does not limit the specific implementation manners.

[0015] It should be noted that if the time length of the first time period is predefined, it is usually fixed and cannot be changed; if the time length of the first time period is preconfigured, it is usually changeable.

[0016] By using the method, the terminal can determine the length of the first time period, and then determine whether the first condition is met by using the first time period, and then determine whether to perform the RRM measurement of the first system. If the length of the first time period is greater than the time interval between the starting time of the RRM measurement of the first system and the time domain unit where the first information is located, the terminal can perform the RRM measurement of the first system, thereby improving the RRM measurement performance of the first system. Otherwise, if the length of the first time period is less than or equal to the time interval between the starting time of the RRM measurement of the first system and the time domain unit where the first information is located, the terminal can skip or not perform the RRM measurement of the first system, thereby improving the transmission performance of service data.

[0017] In a second aspect, a communication method is provided. The method can be applied to a network side, for example, an access network device of the network side, 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. Taking the case where the method is applied to the access network device as an example for description.

[0018] In the method, the first information is sent; in a case where at least a first condition is met, data transmission is performed on a time unit occupied by an RRM measurement of a first system, the RRM measurement being a first RRM measurement after a first time period of the first system, the first time period being located after a time domain unit where the first information is located, the first condition being that a time interval between a starting time of the RRM measurement and the time domain unit where the first information is located is greater than or equal to the first time period; and data transmission is not performed on a time unit occupied by an RRM measurement of a second system.

[0019] By using the method, the network side indicates to skip the RRM measurement of the first system by sending the first information. Further, in a case where the time interval between the starting time of the RRM measurement of the first system and the time domain unit where the first information is located is greater than or equal to the first time period, i.e. in a case where at least the first condition is met, the network side can perform data transmission on the resource occupied by the RRM measurement of the first system, so as to improve the reliability of service data transmission. The implementation manner can reduce the scheduling restriction of service data caused by the RRM measurement of the first system, and reduce the conflict between service data transmission and the RRM measurement, thereby improving the reliability of service data transmission while taking into account the measurement performance, especially in the case of different systems.

[0020] In a possible design, the method further includes: in a case where at least a second condition is met, data transmission is not performed on a time unit occupied by the RRM measurement of the first system. The second condition is that the time interval between the starting time of the RRM measurement and the time domain unit where the first information is located is less than the first time period.

[0021] In a possible design, the method further includes: sending second information, where the second information indicates a length of the first time period.

[0022] The advantages of the second aspect and some implementation manners described above can be referred to the description of the first aspect and some implementation manners, which will not be repeated here.

[0023] In a third aspect, a communication method is provided. The method can be applied to a terminal side, for example, a terminal or a communication module in the terminal, or a circuit or chip 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 a system in package (SIP) chip containing a modem core). The method is described by taking the case where it is applied to a terminal.

[0024] In the method, third information is received; and in a case where at least a third condition is met, a RRM measurement is skipped according to the third information, the RRM measurement being a first RRM measurement after a second time period, the second time period being located after a time domain unit where the third information is located, a length of the second time period being a maximum value of A and B, A representing a reserved length required for skipping a RRM measurement of a first system, B representing a reserved length required for skipping a RRM measurement of a second system, the first system and the second system being different systems; and the third condition is that a time interval between a starting moment of the RRM measurement and the time domain unit where the third information is located is greater than or equal to the second time period.

[0025] Exemplarily, the implementation manner can be applied to a non-standalone networking scenario of an NR system with more RRM measurements of an LTE system. It can be understood that the implementation manner is used to simultaneously constrain the RRM measurement of the first system and the RRM measurement of the second system in a different system scenario, that is, whether to perform or skip the RRM measurement of the first system and whether to perform or skip the RRM measurement of the second system are determined by judging whether at least the third condition is met.

[0026] Optionally, the implementation manner can also simultaneously constrain the RRM measurements of other systems to achieve the purpose of greatly improving the performance of service data transmission.

[0027] With the above method, in a case that the terminal side determines that the time interval between the starting moment of the RRM measurement and the time domain unit where the third information is located is greater than or equal to the second time period, i.e., at least the third condition is met, the terminal skips the RRM measurement according to the third information, and in a case that it is determined that the third condition is not met, i.e., at least the fourth condition is met, the terminal performs the RRM measurement. This implementation can reduce the scheduling restriction caused by the RRM measurement as much as possible, greatly improving the reliability of service transmission. In particular, in the case that the terminal skips the RRM measurement at least when the third condition is met, the RRM measurement can be the RRM measurement of the first system, the RRM measurement of the second system, or the RRM measurement of another system, which can improve the transmission performance of service data as much as possible.

[0028] In a possible design, the method further includes: performing the RRM measurement in a case that at least the fourth condition is met. The fourth condition is that the time interval between the starting moment of the RRM measurement and the time domain unit where the third information is located is less than the second time period.

[0029] With the above method, in a case that the terminal side determines that the time interval between the starting moment of the RRM measurement and the time domain unit where the third information is located is less than the second time period, it indicates that the time interval between the third information and the RRM measurement is small, for example, the terminal can not skip the RRM measurement in time, and therefore the terminal can determine to perform the RRM measurement. This implementation can improve the reliability of service data transmission while also taking into account the RRM measurement performance.

[0030] In a possible design, the method further includes: receiving fourth information, where the fourth information indicates A and B.

[0031] Optionally, the values of A and B can also indicate, for example, that the access network device sends fifth information to the terminal, where the fifth information indicates the value of A, and the access network device sends fifth information to the terminal, where the fifth information indicates the value of B, which is not limited in this regard.

[0032] In a possible design, the length of the second time period is predefined or preconfigured. The predefinition can include predefinition, for example, protocol definition, and the preconfiguration can be implemented by pre-saving corresponding codes, tables, functions, texts, strings, or other information that can indicate relevant information on the terminal side and / or the network side. The specific implementation of the present application is not limited in this regard.

[0033] It should be noted that if the length of the second time period is predefined, it is usually fixed and cannot be changed later; if the length of the second time period is preconfigured, it is usually changeable.

[0034] By using the method, the terminal can determine the values of A and B, and thus determine the reserved time length required for skipping the RRM measurement of the first system and the reserved time length required for skipping the RRM measurement of the second system, and further determine the time length of the second time period. By judging whether the third condition is met, it can be determined whether to perform the RRM measurement. If the time length of the second time period is greater than the time interval between the starting time of the RRM measurement and the time domain unit in which the third information is located, the terminal can perform the RRM measurement, thereby improving the RRM measurement performance. Conversely, if the time length of the second time period is less than or equal to the time interval between the starting time of the RRM measurement and the time domain unit in which the third information is located, the terminal can skip or not perform the RRM measurement, thereby improving the transmission performance of service data.

[0035] In a fourth aspect, a communication method is provided. The method can be applied to a network side, such as an access network device of the network side, 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 functions of the access network device. Take the case where the method is applied to the access network device for description.

[0036] In the method, the third information is sent. In the case where at least the third condition is met, data transmission is performed on the time unit occupied by the RRM measurement, which is the first RRM measurement after the second time period. The second time period is located after the time domain unit in which the third information is located. The time length of the second time period is the maximum value of A and B. A represents the reserved time length required for skipping the RRM measurement of the first system. B represents the reserved time length required for skipping the RRM measurement of the second system. The first system and the second system are different systems. The third condition is that the time interval between the starting time of the RRM measurement and the time domain unit in which the third information is located is greater than or equal to the second time period.

[0037] By using the method, the network side indicates skipping the RRM measurement by sending the third information. Further, in the case where the time interval between the starting time of the RRM measurement and the time domain unit in which the third information is located is greater than or equal to the second time period, i.e. at least the third condition is met, the network side can perform data transmission on the resource occupied by the RRM measurement, so as to improve the reliability of service data transmission. This implementation manner can reduce the scheduling restriction of service data caused by the RRM measurement, reduce the conflict between service data transmission and the RRM measurement, and greatly improve the transmission reliability of service data, especially for the different system scenario.

[0038] In a possible design, the method further includes: in the case where at least the fourth condition is met, not performing data transmission on the time unit occupied by the RRM measurement. The fourth condition is that the time interval between the starting time of the RRM measurement and the time domain unit in which the third information is located is less than the second time period.

[0039] In a possible design, the method further includes: sending fourth information, where the fourth information indicates A and B.

[0094] FIG. 1 is a schematic diagram of a communication system provided by an embodiment of the present application. As shown in FIG. 1, the communication system 10 includes a radio access network (RAN) 100 and a core network (CN) 200. The RAN 100 includes at least one RAN node (such as 110a and 110b in FIG. 1, collectively referred to as 110) and at least one terminal (such as 120a-120j in FIG. 1, collectively referred to as 120). The RAN 100 can also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in FIG. 1), etc. The terminal 120 is connected to the RAN node 110 in a wireless manner. The RAN node 110 is connected to the CN 200 in a wireless or wired manner. The core network device in the CN 200 and the RAN node 110 in the RAN 100 can be different physical devices respectively, or can be the same physical device integrated with the logical functions of the core network and the logical functions of the radio access network.

[0095] The RAN 100 can be a 3GPP related cellular system, e.g., a fourth generation (4G) mobile communication system, a 5G mobile communication system, or a future evolvement system there of. The RAN 100 can also be an open radio access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (WiFi) system. The RAN 100 can also be a communication system in which two or more of the above systems are converged.

[0096] The RAN nodes 110, which can also be referred to as access network devices, RAN entities or access nodes, etc., form part of the communication system and are configured to facilitate wireless access to the communication system by terminals. The RAN nodes 110 in the communication system can be nodes of the same type or nodes of different types. In some scenarios, the roles of the RAN nodes 110 and the terminals 120 are relative, e.g., a net element 120i in Figure 1 can be a helicopter or a drone, which can be configured to be a mobile base station, for a terminal 120j accessing to the RAN 100 through the net element 120i, the net element 120i is a base station; but for the base station 110a, the net element 120i is a terminal. The RAN nodes 110 and the terminals 120 are sometimes referred to as communication apparatuses, e.g., the net elements 110a and 110b in Figure 1 can be understood as communication apparatuses with base station functionalities, and the net elements 120a-120j can be understood as communication apparatuses with terminal functionalities.

[0097] 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 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, an 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.

[0098] 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).

[0099] In different systems, the CU (including open CU-CP (O-CU-CP) and open CU-UP (O-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 an open central unit (O-CU), the DU can also be referred to as an open distributed unit (O-DU), and the RU can also be referred to as an open radio unit (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.

[0100] The terminal 120 can be a device or module with corresponding communication functions for accessing 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) communication, V2X communication, machine-type communication (MTC), internet of things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, remote medical treatment, smart power grid, smart home, 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 embodiments of the present application do not limit the device form of the terminal. The terminal usually has a communication module, circuit or chip for executing corresponding communication functions. The terminal also has program instructions for executing corresponding communication functions.

[0101] The RAN 100 and the terminal 120 can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface; can also be deployed on aircraft, balloons and satellites in the air. The embodiments of the present application do not limit the scenarios in which the RAN 100 and the terminal 120 are located.

[0102] The CN 200 can be a 5G core network or an evolved 5G core network. Taking the 5G core network as an example, the CN 200 includes an access and mobility management function (AMF) network element responsible for services such as mobility management and access management, a session management function (SMF) network element responsible for session management, a user plane function (UPF) network element responsible for user plane packet routing and forwarding and quality of service (QoS) control, a policy control function (PCF) network element, and the like. The above core network elements can work independently or can be combined together to implement certain control functions, for example, the AMF, the SMF, and the PCF can be combined together as a core network device.

[0103] It should be understood that the above naming is only defined for the purpose of distinguishing different functions and should not constitute any limitation on the present application. The present application does not exclude the possibility of using other names in the 5G network and future other networks. For example, in future networks, part or all of the above network elements can use the terms in 5G or other names.

[0104] FIG. 2 is a schematic diagram of another communication system provided by an embodiment of the present application, for example, a schematic diagram of a 5G networking architecture. As shown in FIG. 2, the 5G networking includes standalone (SA) and non-standalone (NSA) networking. In the SA mode, the 5G NR network does not depend on the 4G LTE network, can be independently deployed, has its own core network (for example, a 5G core network) and radio access network, and can provide complete 5G experience such as low latency and high data rate. The SA mode can support the characteristics of 5G including network slicing, ultra-reliable low-latency communication, and massive Internet of Things, is the long-term goal of the 5G network, and requires full deployment of a new 5G core network and radio access network. In the NSA mode, the 5G NR network can work cooperatively with the 4G LTE network, allows the terminal side to be connected to the 4G network and the 5G network at the same time, has the advantages of wide coverage of 4G and high speed of 5G, and the like. The NSA mode is suitable for the initial deployment of 5G, can quickly launch 5G services, and at the same time, utilizes the existing 4G infrastructure.

[0105] As shown in (a) of FIG. 2, the 5G core network in the SA mode can establish a communication connection with the 5G base station through the control plane interface NG-C and / or the user plane interface NG-U; as shown in (b) of FIG. 2, the 5G core network in the SA mode can establish a communication connection with the 4G base station through the NG-C and / or the NG-U; as shown in (c) of FIG. 2, the 4G core network in the NSA mode can establish a communication connection with the 4G base station and the 5G base station simultaneously, wherein the 4G base station is the primary station and the 5G base station is the secondary station, for example, the 4G core network can establish a communication connection with the 4G base station through the control plane interface S1-C and / or the user plane interface S1-U; as shown in (d) of FIG. 2, the 5G core network in the NSA mode can establish a communication connection with the 4G base station and the 5G base station simultaneously, wherein the 5G base station is the primary station and the 4G base station is the secondary station, for example, the 5G core network can establish a communication connection with the 5G base station through the NG-C and / or the NG-U; as shown in (e) of FIG. 2, the 5G core network in the NSA mode can establish a communication connection with the 4G base station and the 5G base station simultaneously, wherein the 4G base station is the primary station and the 5G base station is the secondary station, for example, the 5G core network can establish a communication connection with the 4G base station through the S1-C and / or the S1-U.

[0106] In the NSA mode and the SA mode, there is a heterogeneous system RRM measurement scenario, that is, the terminal side can perform RRM measurement on the NR system or the LTE system. In the NSA mode, the NR base station coexists with the LTE base station. In the SA mode, when the NR network coverage is discontinuous, the LTE network can be used for fallback to improve user experience. In addition, the terminal side can also select the LTE network to bear specific services.

[0107] It can be understood that the above-mentioned FIG. 1 or FIG. 2 is only an example given for understanding and does not constitute a limitation on the protection scope of the present application. The communication method provided by the embodiments of the present application can also involve network elements not shown in FIG. 1 or FIG. 2, and of course the communication method provided by the embodiments of the present application can also only include part of the network elements shown in FIG. 1 or FIG. 2.

[0108] 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. Among them, XR can refer to various environments generated by computing technology and wearable devices that combine reality and virtuality, as well as human-computer interaction, mainly including virtual reality (VR), augmented reality (AR) and other virtual and real interaction technologies. In order to improve the experience of human interaction with the virtual world, XR service has strict requirements on bandwidth and delay. In the downlink transmission process, the encoder of the server generates data content at a fixed frequency (for example, 60 hertz (Hz) or 120 Hz, etc.), and transmits it to the terminal device via the core network and RAN. In the uplink transmission process, the terminal device can collect the current scene image through the built-in camera and continuously upload it to the server at a specific frequency (for example, 60 Hz or 120 Hz, etc.). For example, XR service usually generates data periodically according to a certain frame rate. The service model of the downlink XR service is roughly as follows: AR / VR and cloud game. The AR / VR frame rate can be 60 frames per second (FPS), that is, 60 frames of video images are generated per second, and a video frame appears about every 16.67 ms. The AR / VR frame rate can also be 120 FPS, that is, 120 frames of video images are generated per second, and a video frame appears about every 8.33 ms. The cloud game frame rate can be 60 FPS or 120 FPS, that is, 60 frames of video images are generated per second or 120 frames of video images are generated per second.

[0109] In a mobile cellular network, when a terminal device moves from one cell (base station coverage) to another cell, it needs to be handed over between cells. Before handover, the terminal device needs to measure the signals of the adjacent cells to determine when to hand over. During the measurement period, the terminal device and the access network device preferentially transmit and receive measurement signals, and only a small amount of data signals are transmitted and received, so the data transmission rate during the measurement period is very low, and users using XR devices will perceive that there is a significant delay in data transmission.

[0110] Exemplarily, the measurement includes intra-frequency measurement and inter-frequency measurement. The intra-frequency measurement refers to that a cell where a terminal device currently locates and a target cell to be measured are on a same carrier frequency (center frequency point), for example, the terminal device can perform measurement through a reference signal inserted during data transmission, without affecting data transmission and reception. The inter-frequency measurement refers to that the cell where the terminal device currently locates and the target cell are not on a same carrier frequency, for example, two kinds of radio frequency receivers are installed in the terminal device, and the terminal device measures a frequency point of the current cell and a frequency point of the target cell, but this causes cost increase and interference between different frequency points.

[0111] In an implementation manner, terminal switching is performed based on terminal measurement of SSB, and the terminal implements time and frequency synchronization and acquires necessary system information by receiving and decoding the SSB. In order to obtain the most accurate SSB measurement result, all SSBs of a cell need to be measured as much as possible. Meanwhile, SSBs are not transmitted at all time sequences in a scanning period, and if the terminal searches and measures SSBs at all time sequences, a great power waste will be caused. In order to effectively indicate a time window for the terminal to measure SSB and reduce unnecessary power consumption of the terminal, the concept of SMTC is introduced. The SMTC is a time window configured by a base station for the terminal to measure SSB, and in the time window, the terminal can perform SSB measurement, such as reference signal received power (RSRP) and / or reference signal received quality (RSRQ), between cells, without causing conflict with normal uplink data transmission.

[0112] Exemplarily, the SMTC represents a timing configuration issued by a base station to a terminal through an RRC message when the terminal performs SSB-based measurement on a certain cell, including an SMTC period, an SMTC offset, and an SMTC duration. The protocol defines that the configuration of the SMTC is a frequency point level configuration, including SMTC1 configuration and SMTC2 configuration, and the SMTC2 configuration is an optional configuration. The SMTC1 configuration includes two sub-cells, namely, a periodicityAndOffset (periodicity represents a repetition period of a measurement action; offset represents a starting subframe of the measurement action in the period) and a duration (represents a duration of the measurement action after the measurement action starts). The SMTC period can be 5 ms, 10 ms, 20 ms, 40 ms, 80 ms, or 160 ms. The SMTC offset takes a value between 0 and SMTC period minus 1 ms with a granularity of 1 ms. The SMTC duration takes a value with a granularity of 1 ms, and the length can be 1 ms, 2 ms, 3 ms, 4 ms, or 5 ms. For example, when the SMTC period is 5 ms, the SMTC offset can take a value of 0 ms, 1 ms, 2 ms, 3 ms, or 4 ms, and the SMTC duration can take a value of 1 ms, 2 ms, 3 ms, 4 ms, or 5 ms.

[0113] FIG. 3 is a schematic diagram of a time configuration SMTC of an SSB-based wireless resource management strategy. As shown in FIG. 3, the length of a system frame number (SFN) corresponding to a radio frame can be 10 milliseconds (ms), and one radio frame can include 10 subframes (SF), that is, the length of one radio subframe can be 1 ms. The SFN is a serial number starting from 0 and used to identify a downlink transmission time interval (TTI), for example, the SFN takes a value of 4, 5, 6, or 7. The SMTC period is 2 frames, that is, 20 ms, and the shaded radio subframes represent the SMTC duration, that is, the length of the SSB measurement performed by the terminal, which is 4 ms, and the SMTC offset is 2 ms.

[0114] In another implementation manner, a measurement gap (MG) mode can be used for signal measurement, that is, a measurement gap MG period is reserved, in which the terminal does not send and receive any data, and the receiver is adjusted to the frequency point of the target cell to perform inter-frequency measurement, and then the terminal returns to the service cell communication after the MG period ends. The period in which the terminal suspends the communication with the service cell to measure the inter-frequency neighbor cell or other different radio access technology (RAT) cells is the MG period.

[0115] The MG is usually sent by the base station to the terminal through an RRC message, including: measurement gap repetition period (MGRP), gap offset, and measurement gap length (MGL). The MGRP is a specified gap period, that is, the interval length between the start time of the current MG period and the start time of the next MG period. The MGRP can be 20 ms, 40 ms, 80 ms, or 160 ms; the gap offset is the offset of the gap pattern, which can range from 0 to 159 and can be an integer, for a total of 160 offset values. The offset value points to the starting subframe in the period, and the value range is from 0 to MGRP-1. For example, if the period is 20 ms, the offset range is 0 to 19; the MGL can be 1.5 ms, 3 ms, 3.5 ms, 4 ms, 5.5 ms, or 6 ms.

[0116] The starting position of the MG configuration can satisfy: SF = gapoffset mod 10 (2) T = MGRP / 10 (3)

[0117] Wherein, mod is the remainder, is the floor function. The starting time of the MG period can satisfy the above formula (1), and the starting SF of the MG period in the SFN can satisfy the above formula (2).

[0118] During the MG activation period, the terminal will not transmit any other signals or data except for some important signals (for example, signals related to the access process), that is, the MG has a higher priority than data transmission and reception. A terminal can be configured with multiple MGs. The base station can configure a priority for each MG using the high-level parameter gapPriority-r17. Usually, the MG is configured separately, so there is a possibility that two MGs will conflict in the time domain, that is, the duration of the two MGs overlaps in the time domain. At this time, the terminal can select the MG with a higher priority for measurement.

[0119] FIG. 4 is a schematic diagram of a measurement gap MG. One SFN corresponds to a radio frame with a length of 10 ms, and one radio frame can include 10 radio subframes SF, that is, the length of one radio subframe can be 1 ms. As shown in FIG. 4, the MGRP is 2 frames, that is, 20 ms, and the shaded radio subframes represent the MGL, that is, the duration of the inter-frequency measurement of the target cell by the terminal, which is 6 ms, and the gapoffset is 13 ms.

[0120] FIG. 5 is a schematic diagram of a measurement gap MG colliding with a service data transmission period. In XR services, due to the non-integer data arrival period of XR, for example, for an XR video with a frame rate of 60 frames per second (FPS), the frame arrival period is 1 / 60 s, that is, 60 frames of video images are generated per second, and a video frame occurs approximately every 16.67 ms. Due to the mismatch between the XR service arrival period and the MG measurement period, the XR service data transmission can collide with the MG. As shown in FIG. 5, for an XR video with a frame rate of 60 FPS, when a mode 0 configuration is used, that is, a configuration with an MGL of 6 ms and an MGRP of 40 ms, the transmission of 2 frames out of every 6 frames is affected by the MG, for example, the 4th frame and the 6th frame. That is, in the time domain, the data transmission of the XR service collides with the MG, the XR capacity decreases significantly, and the reliability of the XR service is reduced.

[0121] To reduce the collision between the data transmission of the XR service and the MG scheduling limit or the SMTC scheduling limit in the time domain, the network side can indicate the terminal side to skip the MG scheduling limit or the SMTC scheduling limit by sending a DCI, so as to improve the transmission reliability of the XR service.

[0122] As an example, by adding bit information in the DCI, it is indicated whether the first scheduling limit after the last symbol of the physical downlink control channel (PDCCH) carrying the DCI and satisfying a minimum time offset is canceled. For example, the position relationship in the time domain of the PDCCH, the scheduling limit of the MG, and the scheduling limit of the SMTC generally satisfies at least one of the following:

[0123] (1) The start position of the symbol of the PDCCH can start at any symbol in a slot, and the symbol length is {1, 2, 3};

[0124] (2) The scheduling limit of the MG is in ms granularity;

[0125] (3) The scheduling limit of the SMTC includes the symbol of the SSB and each of the symbols before and after the SSB;

[0126] (4) The symbol position of the SSB includes two types: {2, 8}+14*n, or {4, 8, 16, 20}+28*n, where n represents the index of the slot in the period of sending the SSB.

[0127] Exemplarily, the minimum time offset needs to be predefined or preconfigured, and the value thereof is usually related to DCI processing time, RRM measurement cancellation preparation time, subcarrier spacing (SCS), and the like.

[0128] Based on this, the network side can indicate, by sending the DCI, whether the first RRM measurement after the last symbol of the PDCCH carrying the DCI and after satisfying the minimum time offset is cancelled (or skipped). It can be understood that skipping the first RRM measurement can reduce the scheduling restriction caused to the transmission of service data, but this will affect the RRM measurement performance, and may cause the accuracy of cell switching and the efficiency of resource management to decrease. The scenario or range to which the first RRM measurement applies is not clear, making the behavior of skipping the first RRM measurement ambiguous, resulting in that effective RRM measurement skipping optimization cannot be performed for the inter-system scenario, and further affecting the overall service experience of users. Therefore, in an actual communication system, there is an urgent need for an RRM measurement skipping scheme, for example, designing the condition of RRM measurement skipping, and optimizing the range to which the RRM measurement skipping applies, so as to improve the overall service experience of users.

[0129] In view of this, the present application provides a communication method and device, by judging whether the time interval between the starting time of the RRM measurement of the first system and the time domain unit where the first information is located is greater than or equal to the first time period, that is, in the case of determining that at least the first condition is met, the terminal side skips the RRM measurement of the first system according to the indication of the network side. In addition, the terminal side can perform the RRM measurement of the other system (for example, the second system). The implementation manner can not only reduce the scheduling restriction caused by the RRM measurement of the first system, improve the transmission reliability of service data, but also can take into account the RRM measurement performance of the second system, and improve the overall service experience of users for the inter-system scenario.

[0130] The communication method and device provided by the present application will be further introduced below in combination with the 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 performed by the access network device in the present application can also be implemented by a module (such as a circuit, a chip or a chip system, etc.) in the access network device, or a logical node, a logical module or software capable of implementing all or part of the network function; the method performed by the terminal in the present application can also be implemented by a communication module or a circuit or 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 communication function in the terminal.

[0131] FIG. 6 is a schematic flowchart of a method 600 for measurement provided by the present application. As shown in FIG. 6, the method comprises the following steps.

[0132] S610, the access network device sends first information to the terminal.

[0133] Correspondingly, the terminal receives the first information from the access network device.

[0134] The first information can indicate skipping RRM measurement of the first system.

[0135] It can be understood that the RRM measurement of the first system is the first RRM measurement after a first time period in the first system, and the first time period is after the time domain unit where the first information is located. In other words, the RRM measurement of the first system refers to the first RRM measurement (the first gap / restriction occasion) after the first time period in the first system and after the time domain unit where the first information is located.

[0136] Exemplarily, the first system can be an NR system, or an LTE system, or other systems, which are not limited.

[0137] Exemplarily, the RRM measurement can be MG measurement, or SMTC measurement, or other RRM measurements, which are not limited.

[0138] Exemplarily, the length of the first time period can be referred to as a minimum time offset. The first time period can be after the last symbol (or the last slot) occupied by the PDCCH carrying the first information, and before the starting time of the RRM measurement of the first system. For example, the starting time of the first time period can be the last symbol occupied by the PDCCH carrying the first information, or the first symbol after the last symbol occupied by the PDCCH carrying the first information, which is not limited.

[0139] In the present application, the size of the first time period in the first system can be predefined or preconfigured, or can also be configured by the network side through signaling, which is not limited.

[0140] The first time period can include one or more time domain units (or time units), which can include a radio frame (RF), a subframe, a frame, a half subframe, a half frame, a slot, a mini-slot, a partial slot, or an orthogonal frequency division multiplexing (OFDM) symbol, and the like.

[0141] The first time period (or the length of the first time period) can be determined in various manners.

[0142] In an implementation manner, the method 600 further includes: the access network device sends second information to the terminal, and the terminal receives the second information from the access network device, where the second information indicates the length of the first time period. For example, the length of the first time period can be carried in the second information, or the start time and the end time of the first time period can be carried in the second information.

[0143] The second information can be sent before or after the step S610, or before the step S620.

[0144] In another implementation manner, the length of the first time period is predefined or preconfigured. The predefinition can include predefinition, such as protocol definition, and the preconfiguration can be implemented by pre-storing corresponding codes, tables, functions, texts, strings, or other information indicating manners on the terminal side and / or the network side, and the specific implementation manner is not limited herein.

[0145] It should be noted that if the length of the first time period is predefined, it is usually fixed and cannot be changed later; if the length of the first time period is preconfigured, it is usually changeable.

[0146] The specific value and unit of the length of the first time period are not limited in the present application. For example, the length of the first time period can be 4 symbols, 5 symbols, or 6 symbols, or other values. For another example, the length of the first time period can be 1 slot, 2 slots, or 3 slots, or other values. It can be understood that different systems can correspond to different lengths of the first time period. For example, for an NR system, the length of the first time period can be 2 slots, for an LTE system, the length of the first time period can be 1 slot, and the like. The specific value can be determined according to the data transmission or channel measurement requirements, and the like.

[0147] Exemplarily, the first information can be carried in a downlink channel, for example, a PDCCH or a PDSCH. Specifically, the first information can be one bit information in DCI carried in the PDCCH, which can occupy the first 3 symbols of a slot.

[0148] Exemplarily, the first information can be DCI signaling, or can be medium access control-control element (MAC CE) signaling, or can also be RRC signaling, which is not limited.

[0149] The bit size occupied by the first information is not specifically limited. For example, the size of the first information can be 1 bit, and bit "1" indicates skipping the RRM measurement of the first system, and bit "0" indicates performing or not skipping the RRM measurement of the first system; or vice versa, bit "0" indicates skipping the RRM measurement of the first system, and bit "1" indicates performing or not skipping the RRM measurement of the first system. For another example, the size of the first information can also be 2 bits, 3 bits, or 4 bits, and the like, which is not limited.

[0150] Optionally, before step S610 is performed, the method 600 further includes: the access network device sends RRM measurement configuration information to the terminal through RRC signaling, and correspondingly, the terminal receives the RRM measurement configuration information from the access network device, and configures the starting position, period, measurement length, and the like of the related parameters corresponding to at least one RRM measurement (for example, MG measurement or SMTC measurement) according to the RRM measurement configuration information. The specific implementation mode and related interpretation can be referred to the related description of the above-mentioned FIG. 3 or FIG. 4, which is not described here for brevity.

[0151] S620, in the case of at least satisfying the first condition, the terminal skips the RRM measurement of the first system according to the first information.

[0152] The first condition is that a time interval between a starting moment of the RRM measurement of the first system and a time domain unit in which the first information is located is greater than or equal to a first time period.

[0153] It can be understood that the first condition can be that a time interval between a starting moment of the RRM measurement of the first system and a first time unit after the time domain unit in which the first information is located is greater than or equal to the first time period, or the first condition can be that a time interval between a starting moment of the RRM measurement of the first system and a last time unit in the time domain unit in which the first information is located is greater than or equal to the first time period, and the disclosure does not limit this.

[0154] As described above, the starting moment of the first time period can be a last symbol (for example, a last time unit in the time domain unit in which the first information is located) occupied by the PDCCH carrying the first information, or a first symbol (for example, a first time unit after the time domain unit in which the first information is located) after the last symbol occupied by the PDCCH carrying the first information. That is, the starting moment of the first time period and the time interval can be the same.

[0155] For example, the first information occupies symbols 0-2 of slot 1, and the starting moment of the RRM measurement of the first system is symbol 0 of slot 3. The first condition is that a time interval between symbol 3 of slot 1 and symbol 0 of slot 3 is greater than or equal to the first time period, or the first condition is that a time interval between symbol 2 of slot 1 and symbol 0 of slot 3 is greater than or equal to the first time period.

[0156] Optionally, the terminal side and the network side can perform data transmission on the time domain unit occupied by the RRM measurement of the first system, improve the transmission amount of service data, and improve the reliability of service transmission.

[0157] It should be noted that, in the case of at least satisfying the first condition, the terminal skips the RRM measurement of the first system according to the first information, which can be understood as: as long as the first condition is satisfied, it is determined to skip the RRM measurement of the first system. However, the technical solution of the present application does not exclude other schemes, that is, in the case of simultaneously satisfying the first condition and other condition #1, the terminal skips the RRM measurement of the first system according to the first information.

[0158] For example, the other condition #1 here can include at least one of the following:

[0159] (1) the length of the RRM measurement of the first system is greater than or equal to a first length;

[0160] Or, the duration of the RRM measurement of the first system is not less than a first length. It can be understood that if the measurement duration of the RRM measurement of the first system is too small, the RRM measurement of the first system has less impact on the transmission of service data, and it is also acceptable to not skip the RRM measurement of the first system.

[0161] The determination manner and specific value of the first length are not limited. For example, the first length can be predefined or preconfigured, or can also be indicated or configured by the network side through signaling. For example, the first length can be 4 symbols, or 6 symbols, or other unit length values.

[0162] (2) The type of the RRM measurement of the first system is a specific type #1.

[0163] It can be understood that the measurement duration of the specific type #1 is longer.

[0164] Exemplarily, the type of the RRM measurement of the first system can be MG measurement. The duration of the scheduling restriction caused by the MG measurement is longer, for example, can be 2 time slots.

[0165] The above is only an example given for the convenience of understanding, and other schemes are not excluded. The number of other conditions #1 and the specific condition content are not limited.

[0166] Optionally, the method 600 further includes: in a case where at least a second condition is met, performing, by the terminal, the RRM measurement of the first system. The second condition is that the time interval between the starting moment of the RRM measurement of the first system and the time domain unit where the first information is located is less than a first time period.

[0167] The specific implementation manner of the terminal performing the RRM measurement of the first system is not limited in the present application, and can be referred to the related description in the prior art. For the sake of brevity, no further description is given here.

[0168] It can be understood that the second condition can be that the time interval between the starting moment of the RRM measurement of the first system and the first time unit after the time domain unit where the first information is located is less than the first time period, or the second condition can be that the time interval between the starting moment of the RRM measurement of the first system and the last time unit in the time domain unit where the first information is located is less than the first time period, which is not limited.

[0169] For example, the first information occupies symbol 0-symbol 2 of time slot 1, and the starting moment of the RRM measurement of the first system is symbol 0 of time slot 3. The second condition is that the time interval between symbol 3 of time slot 1 and symbol 0 of time slot 3 is less than the first time period, or the second condition is that the time interval between symbol 2 of time slot 1 and symbol 0 of time slot 3 is less than the first time period.

[0170] It should be noted that in the case of at least satisfying the second condition, the terminal performs the RRM measurement of the first system, which can be understood as: as long as the second condition is satisfied, it is determined to perform the RRM measurement of the first system. However, the technical solution of the present application does not exclude other schemes, that is, in the case of simultaneously satisfying the second condition and other condition #2, the terminal performs the RRM measurement of the first system.

[0171] For example, the other condition #2 here can include at least one of the following:

[0172] (1) The duration of the RRM measurement of the first system is less than or equal to the first length;

[0173] That is, the duration of the RRM measurement of the first system is not greater than the first length. It can be understood that if the measurement duration of the RRM measurement of the first system is too large, the RRM measurement of the first system has a greater impact on the transmission of service data, and the terminal determines to skip the RRM measurement of the first system to improve the service transmission performance.

[0174] (2) The type of the RRM measurement of the first system is a specific type #2.

[0175] It can be understood that the measurement duration of the specific type #2 is shorter.

[0176] For example, the type of the RRM measurement of the first system can be SMTC measurement. The duration of the scheduling restriction caused by the SMTC measurement is relatively short, for example, it can be 4 symbols.

[0177] The above is only an example given for easy understanding for the other condition #2 that is satisfied for performing the RRM measurement of the first system, and does not exclude other schemes. The number of other conditions #2 and the specific condition content are not limited.

[0178] By using the method, the terminal can determine whether to skip the RRM measurement of the first system after judging the relationship between the time interval between the starting moment of the RRM measurement of the first system and the time domain unit where the first information is located and the size of the first time period, that is, in the case of at least meeting the first condition, the terminal can skip the RRM measurement of the first system according to the first information; in the case of at least meeting the second condition, the terminal can not skip the RRM measurement of the first system, or perform the RRM measurement of the first system. The method can reduce the scheduling restriction of the RRM measurement behavior on the service data, improve the service transmission performance, and take into account the measurement performance.

[0179] In S630, the terminal performs the RRM measurement of the second system.

[0180] The present application does not limit the specific implementation of the terminal performing the RRM measurement of the second system, and the related description can be referred to. For the sake of brevity, no further description is given here.

[0181] It should be noted that the terminal in the embodiments of the present application supports the first system and the second system at the same time, and supports the RRM measurement of the first system and the RRM measurement of the second system.

[0182] Exemplarily, the first system and the second system are different systems. For example, the second system can be an NR system, or an LTE system, or other systems, which are not limited. For example, if the first system is an NR system, the second system can be an LTE system or other systems; if the first system is an LTE system, the second system can be an NR system or other systems, which are not limited.

[0183] The present application does not limit whether the frequencies supported (or corresponding) by the first system and the second system are the same. For example, if the first system is an NR system, the frequency supported (or corresponding) by the first system is f1, the second system is an LTE system, and the frequency supported (or corresponding) by the second system is f2, then f1=f2 or f1≠f2. That is, the RRM measurement of the first system and the RRM measurement of the second system can be same-frequency measurement or different-frequency measurement, which is not limited.

[0184] That is, the terminal supports the first system and the second system simultaneously, and in a case where it is determined that the first condition is at least satisfied, the terminal skips RRM measurement of the first system according to the first information. For RRM measurement of the second system, the terminal performs the RRM measurement of the second system regardless of whether the first condition is satisfied or not, or in other words, as long as there is RRM measurement of the second system, the terminal performs the RRM measurement of the second system to improve the RRM measurement performance of the second system. That is, while improving the RRM measurement performance of the second system, the RRM measurement behavior of the first system is reduced to realize the scheduling restriction caused by the transmission of service data, or in other words, to improve the transmission performance of service data. Therefore, it can be understood that this implementation mainly serves to restrict the RRM measurement of the first system, that is, whether to skip the RRM measurement of the first system is determined by judging whether the first condition is at least satisfied, while the RRM measurement of the second system is not restricted, that is, the terminal determines to perform the RRM measurement of the second system.

[0185] Based on the above scheme, after receiving the first information, in a case where it is determined that the time interval between the starting moment of the RRM measurement of the first system and the time domain unit where the first information is located is greater than or equal to the first time period, that is, the first condition is at least satisfied, the terminal skips the RRM measurement of the first system according to the first information, and in a case where it is determined that the first condition is not satisfied, that is, the second condition is at least satisfied, the terminal performs the RRM measurement of the first system. In addition, for the RRM measurement of the second system supported by the terminal, the terminal performs the RRM measurement of the second system regardless of whether the first condition or the second condition is satisfied. This implementation can reduce the transmission conflict caused by the scheduling restriction of the RRM measurement of the first system, and can take into account the measurement performance while improving the reliability of service transmission. In particular, in the inter-system scenario, the terminal skips the RRM measurement of the first system in a case where the first condition is at least satisfied, which can improve the transmission performance of service data. At the same time, since the terminal performs or does not skip the RRM measurement of the second system, the RRM measurement performance of the second system can be improved. For example, this implementation can be applied to the independent networking scenario of the NR system with less RRM measurement of the LTE system.

[0186] Next, the implementation of whether the terminal skips the RRM measurement of the first system and the RRM measurement of the second system will be illustrated by combining FIG. 7 and FIG. 8. It should be pointed out that FIG. 7 is mainly applied to restrict the RRM measurement of the first system, for example, whether to skip the RRM measurement of the NR system is determined by judging whether the first condition is at least satisfied. In contrast, FIG. 8 is mainly applied to restrict the RRM measurement of the second system, for example, whether to skip the RRM measurement of the LTE system is determined by judging whether the first condition is at least satisfied.

[0187] FIG. 7 is a diagram of skipping RRM measurement according to an embodiment of the present application. As shown in FIG. 7, the horizontal axis represents time domain (for example, taking time slot as an example), and the vertical axis represents frequency domain (for example, taking resource block (RB) as an example). For example, it is assumed that the first system is NR system, and the second system is LTE system, for example, there are three RRM measurements (in time sequence from left to right: RRM measurement #1, RRM measurement #2 and RRM measurement #3), wherein the RRM measurement #1 is RRM measurement of the NR system, the RRM measurement #2 is RRM measurement of the LTE system, and the RRM measurement #3 is RRM measurement of the NR system or RRM measurement of the LTE system. The symbol of the PDCCH carrying the first information occupies the first three symbols of the time slot, the first time period occupies 2 time slots, and the starting time of the first time period is the first symbol after the symbol of the PDCCH carrying the first information. The first information is used to indicate skipping RRM measurement of the NR system.

[0188] Specifically, for the RRM measurement #1, since the time interval (for example, time interval #1) between the starting time of the first RRM measurement (i.e., RRM measurement #1) of the NR system after the symbol of the first information and the first symbol after the symbol of the first information is greater than the first time period, i.e., satisfying the first condition, the terminal determines to skip the RRM measurement of the NR system, i.e., skipping the RRM measurement #1. For the RRM measurement #2, since the RRM measurement #2 is RRM measurement of the LTE system, the terminal determines to perform the RRM measurement #2, or in other words, does not skip the RRM measurement #2. For the RRM measurement #3, if the RRM measurement #3 is RRM measurement of the LTE system, the terminal determines to perform the RRM measurement #3, or in other words, does not skip the RRM measurement #3. That is, whether the first condition is satisfied (for example, time interval #2 is greater than the first time period, or time interval #3 is less than the first time period), the terminal performs RRM measurement of the LTE system. If the RRM measurement #3 is RRM measurement of the NR system, since the time interval (for example, time interval #3) between the starting time of the first RRM measurement (i.e., RRM measurement #3) of the NR system after the symbol of the first information and the first symbol after the symbol of the first information is less than the first time period, i.e., not satisfying the first condition or satisfying the second condition, the terminal determines to skip the RRM measurement of the NR system, i.e., skipping the RRM measurement #3.

[0189] In this implementation, by judging whether the first condition is satisfied, the RRM measurement of the NR system is restricted, i.e., the RRM measurement of the NR system is reduced, the transmission performance of service data is improved, and the overall experience of the service of the terminal is improved. At the same time, the RRM measurement of the LTE system is not skipped, and the RRM measurement performance of the LTE system can be improved.

[0190] FIG. 8 is a diagram of skipping RRM measurement according to an embodiment of the present application. As shown in FIG. 8, the horizontal axis represents the time domain (for example, taking slots as an example), and the vertical axis represents the frequency domain (for example, taking resource blocks RB as an example). For example, it is assumed that the first system is an LTE system, and the second system is an NR system, for example, there are three RRM measurements (in time sequence from left to right: RRM measurement #1, RRM measurement #2, and RRM measurement #3), wherein RRM measurement #1 is an RRM measurement of the LTE system, RRM measurement #2 is an RRM measurement of the NR system, and RRM measurement #3 is an RRM measurement of the NR system or an RRM measurement of the LTE system. The symbol of the PDCCH carrying the first information occupies the first three symbols of the slot, the first time period occupies 2 slots, and the starting time of the first time period is the first symbol after the symbol of the PDCCH carrying the first information. The first information is used to indicate skipping the RRM measurement of the LTE system.

[0191] Specifically, for RRM measurement #1, since the time interval (for example, time interval #1) between the starting time of the first RRM measurement (i.e., RRM measurement #1) of the LTE system after the symbol of the first information and the first symbol after the symbol of the first information is greater than the first time period, i.e., the first condition is met, the terminal determines to skip the RRM measurement of the LTE system, i.e., to skip RRM measurement #1. For RRM measurement #2, since the RRM measurement #2 is an RRM measurement of the NR system, the terminal determines to perform RRM measurement #2, or in other words, does not skip RRM measurement #2. For RRM measurement #3, if the RRM measurement #3 is an RRM measurement of the NR system, the terminal determines to perform RRM measurement #3, or in other words, does not skip RRM measurement #3. That is, whether the first condition is met (for example, time interval #2 is greater than the first time period, or time interval #3 is less than the first time period), the terminal performs the RRM measurement of the NR system. If the RRM measurement #3 is an RRM measurement of the LTE system, since the time interval (for example, time interval #3) between the starting time of the first RRM measurement (i.e., RRM measurement #3) of the LTE system after the symbol of the first information and the first symbol after the symbol of the first information is less than the first time period, i.e., the first condition is not met or the second condition is met, the terminal determines to skip the RRM measurement of the LTE system, i.e., to skip RRM measurement #3.

[0192] In this implementation, the RRM measurement of the LTE system is constrained by judging whether the first condition is met, i.e., the RRM measurement of the LTE system is reduced, the transmission performance of service data is improved, and the overall experience of the service of the terminal is improved. At the same time, the RRM measurement of the NR system is not skipped, which can improve the RRM measurement performance of the NR system.

[0193] It should be noted that the above FIG. 7 and FIG. 8 are only example illustrations given for the convenience of understanding, and other solutions are not excluded.

[0194] It can be understood that the technical solutions of the above FIG. 6 to FIG. 8 are mainly used to restrict the RRM measurement of the first system in the inter-system scenario, that is, whether to perform or skip the RRM measurement of the first system is determined by judging whether the first condition is met. In contrast, for the RRM measurement of the second system, the terminal does not need to judge whether the first condition is met, that is, the terminal determines not to skip or perform the RRM measurement of the second system, which can improve the service transmission reliability under the premise of reducing the RRM measurement of the first system, and can also take into account the RRM measurement performance of the second system.

[0195] Next, another technical solution of the present application will be illustrated in conjunction with FIG. 9 and FIG. 10. It can be understood that this technical solution is used to simultaneously restrict the RRM measurement of the first system and the RRM measurement of the second system in the inter-system scenario, that is, whether to perform or skip the RRM measurement of the first system and whether to perform or skip the RRM measurement of the second system is determined by judging whether the third condition is met. This implementation mode reduces the scheduling restriction of the RRM measurement behavior on the service data transmission as much as possible, and improves the service transmission performance. Alternatively, this implementation mode can also simultaneously restrict the RRM measurement of other systems to achieve the purpose of greatly improving the service data transmission performance.

[0196] FIG. 9 is a schematic flowchart of a method 900 for measurement provided by the present application. As shown in FIG. 9, the method includes the following steps.

[0197] S910, the access network device sends third information to the terminal;

[0198] Correspondingly, the terminal receives the third information from the access network device.

[0199] The third information can indicate skipping the RRM measurement.

[0200] Exemplarily, the RRM measurement can be MG measurement, or SMTC measurement, or other RRM measurement, which is not limited.

[0201] Exemplarily, the RRM measurement can be the RRM measurement of the first system, or the RRM measurement of the second system, or the RRM measurement of other systems, which is not limited. The first system can be an NR system, or an LTE system, or other systems. The second system can be an NR system, or an LTE system, or other systems.

[0202] In the embodiments of the present application, the first system and the second system can be different systems. For example, if the first system is an NR system, the second system can be an LTE system or other system; if the first system is an LTE system, the second system can be an NR system or other system.

[0203] The present application does not limit whether the frequencies supported (or corresponding to) by the first system and the second system are the same, and specific descriptions can be referred to the related descriptions of the method 600.

[0204] It can be understood that the RRM measurement is the first RRM measurement after the second time period, and the second time period is located after the time domain unit of the third information. In other words, the RRM measurement refers to the first RRM measurement after the second time period located after the time domain unit of the third information.

[0205] For example, the length of the second time period can be referred to as a minimum time offset, and the second time period can be located after the last symbol (or the last time slot) occupied by the PDCCH carrying the first information and before the starting moment of the RRM measurement. For example, the starting moment of the second time period can be the last symbol occupied by the PDCCH carrying the first information, or the first symbol after the last symbol occupied by the PDCCH carrying the first information, which is not limited specifically.

[0206] As an example, the length of the second time period can be the maximum value of A and B. Wherein, A represents the reserved time length required for skipping the RRM measurement of the first system, and B represents the reserved time length required for skipping the RRM measurement of the second system. In other words, the reserved time length required for skipping the RRM measurement of the first system can be understood as the minimum time offset required for skipping the RRM measurement of the first system, and the reserved time length required for skipping the RRM measurement of the second system can be understood as the minimum time offset required for skipping the RRM measurement of the second system. For example, A represents a minimum time offset #1 corresponding to the RRM measurement of the first system, and B represents a minimum time offset #2 corresponding to the RRM measurement of the second system. The specific values of the minimum time offset #1 and the minimum time offset #2 can be referred to the related descriptions of the method 600.

[0207] In the present application, the size of the second time period can be predefined or preconfigured, or can also be configured by the network side through signaling, which is not limited.

[0208] The present application does not limit the form of the second time period, which can be referred to the related descriptions of the first time period in the method 600.

[0209] The application does not limit the determination manner of the second time period (or the length of the second time period).

[0210] In an implementation manner, the method 900 further includes: the access network device sends fourth information to the terminal, and the terminal receives the fourth information from the access network device, where the fourth information indicates the values of A and B. Optionally, the values of A and B can also be indicated respectively, for example, the access network device sends fifth information to the terminal, where the fifth information indicates the value of A, and the access network device sends fifth information to the terminal, where the fifth information indicates the value of B, and the application does not limit this.

[0211] The application does not limit the sending time of the fourth information. For example, the fourth information can be sent before the step S910 or after the step S910, and the application does not limit this. Or, the fourth information can be sent before the step S920.

[0212] In another implementation manner, the length of the second time period is predefined or preconfigured. The predefinition can include predefinition, such as protocol definition, and the preconfiguration can be implemented by pre-storing corresponding codes, tables, functions, texts, strings or other information indicating manners on the terminal side and / or the network side, and the application does not limit the specific implementation manner.

[0213] It should be noted that if the length of the second time period is predefined, it is usually fixed and cannot be changed subsequently; if the length of the second time period is preconfigured, it is usually changeable.

[0214] The application does not limit the specific value and unit of the length of the second time period, and the related description of the first time period in the above method 600 can be referred to.

[0215] Exemplarily, the third information can be carried in a downlink channel, such as a PDCCH or a PDSCH. For example, the third information can be one bit information in DCI carried in the PDCCH, and the PDCCH can occupy the first 3 symbols of a slot.

[0216] Exemplarily, the third information can be DCI signaling, or MAC CE signaling, or RRC signaling, and the application does not limit this.

[0217] The application does not limit the bit size occupied by the third information. For example, the size of the third information can be 1 bit, 2 bits, 3 bits, or 4 bits, and the specific implementation manner can be referred to the related description of the above method 600.

[0218] Optionally, before performing step S910, the method 900 further includes: the access network device sends RRM measurement configuration information to the terminal through RRC signaling, and correspondingly, the terminal receives the RRM measurement configuration information from the access network device, and configures the starting position, period, measurement length, and other related parameters corresponding to at least one RRM measurement according to the RRM measurement configuration information. For brevity, the specific implementation and related interpretation can refer to the related description of FIG. 3 or FIG. 4 above.

[0219] S920, in the case of at least satisfying the third condition, the terminal skips the RRM measurement according to the third information.

[0220] The third condition is that the time interval between the starting time of the RRM measurement and the time domain unit where the third information is located is greater than or equal to the second time period.

[0221] It can be understood that the third condition can be that the time interval between the starting time of the RRM measurement and the first time unit after the time domain unit where the third information is located is greater than or equal to the second time period, or the third condition can be that the time interval between the starting time of the RRM measurement and the last time unit in the time domain unit where the third information is located is greater than or equal to the second time period, which is not limited.

[0222] As shown above, the starting time of the second time period can be the last symbol occupied by the PDCCH carrying the first information (for example, the last time unit in the time domain unit where the first information is located), or the first symbol after the last symbol occupied by the PDCCH carrying the first information (for example, the first time unit after the time domain unit where the first information is located). That is, the starting time of the second time period and the time interval can be the same.

[0223] For example, the third information occupies symbols 0-2 of slot 0, and the starting time of the RRM measurement is symbol 0 of slot 4. The third condition is that the time interval between symbol 3 of slot 0 and symbol 0 of slot 4 is greater than or equal to the second time period, or the third condition is that the time interval between symbol 2 of slot 0 and symbol 0 of slot 4 is greater than or equal to the second time period.

[0224] Optionally, the terminal side and the network side can perform data transmission on the time domain unit occupied by the RRM measurement of the first system, improve the transmission amount of service data, and improve the reliability of service transmission.

[0225] It should be noted that, in the case of at least satisfying the third condition, the terminal skips the RRM measurement according to the third information, which can be understood as: as long as the first condition is satisfied, it is determined to skip the RRM measurement. However, the technical solution of the present application does not exclude other solutions, that is, in the case of simultaneously satisfying the first condition and other condition #3, the terminal skips the RRM measurement according to the third information.

[0226] For example, the other condition #3 here can include at least one of the following:

[0227] (1) The duration of the RRM measurement is greater than or equal to a second length;

[0228] That is, the duration of the RRM measurement is not less than the second length. It can be understood that if the measurement duration of the RRM measurement is too small, the RRM measurement has less impact on the transmission of service data, and it is also acceptable not to skip the RRM measurement.

[0229] The determination manner and specific value of the second length are not limited. For example, the second length can be predefined or preconfigured, or can also be indicated or configured by the network side through signaling. For example, the second length can be 2 symbols, or 3 symbols, or other unit length values.

[0230] (2) The type of the RRM measurement is a specific type #3.

[0231] It can be understood that the measurement duration of the specific type #3 is longer.

[0232] For example, the type of the RRM measurement can be MG measurement. The scheduling restriction caused by the MG measurement has a longer duration, for example, which can be 2 time slots.

[0233] The above is only an example given for easy understanding, and other solutions are not excluded. The number of other conditions #3 and the specific condition content are not limited.

[0234] Optionally, the method 900 further includes: in the case of at least satisfying a fourth condition, the terminal performs the RRM measurement. The fourth condition is that the time interval between the starting time of the RRM measurement and the time domain unit where the third information is located is less than a second time period.

[0235] The specific implementation manner of the terminal performing the RRM measurement is not limited in the present application, and can be referred to the related description in the prior art. For brevity, it is not described here.

[0236] It can be understood that the fourth condition can be that a time interval between the starting moment of the RRM measurement and a first time unit after the time domain unit in which the third information is located is less than the second time period; or the fourth condition can be that a time interval between the starting moment of the RRM measurement and a last time unit in the time domain unit in which the third information is located is less than the second time period, which is not limited.

[0237] For example, the third information occupies symbols 0-2 of a time slot 2, and the starting moment of the RRM measurement is symbol 0 of a time slot 4. The fourth condition is that a time interval between symbol 3 of the time slot 2 and symbol 0 of the time slot 4 is less than the second time period, or the fourth condition is that a time interval between symbol 2 of the time slot 2 and symbol 0 of the time slot 4 is less than the second time period.

[0238] It should be noted that in the case of at least meeting the fourth condition, the terminal performs the RRM measurement, which can be understood as: as long as the fourth condition is met, it is determined to perform the RRM measurement. However, the technical scheme of the present application does not exclude other schemes, that is, in the case of simultaneously meeting the fourth condition and other condition #4, the terminal performs the RRM measurement.

[0239] For example, the other condition #4 here can include at least one of the following:

[0240] (1) The duration of the RRM measurement is less than or equal to a second length;

[0241] That is, the duration of the RRM measurement is not greater than the second length. It can be understood that if the measurement duration of the RRM measurement is too large, the RRM measurement has a greater impact on the transmission of service data, and the terminal determines to skip the RRM measurement to improve the service transmission performance.

[0242] (2) The type of the RRM measurement is a specific type #4.

[0243] It can be understood that the measurement duration of the specific type #4 is relatively short.

[0244] For example, the type of the RRM measurement can be SMTC measurement. The duration of the scheduling restriction caused by the SMTC measurement is relatively short, for example, it can be 4 symbols.

[0245] The above other condition #4 that is met for performing the RRM measurement is only an example given for easy understanding, and other schemes are not excluded. The number of other condition #4 and the specific condition content are not limited.

[0246] By using the above method, after the terminal side determines the size relationship between the time interval between the starting moment of the RRM measurement and the time domain unit where the third information is located and the second time period, it can determine whether to skip the RRM measurement, that is, in the case of at least meeting the third condition, the terminal side can skip the RRM measurement according to the third information; in the case of at least meeting the fourth condition, the terminal side can not skip the RRM measurement, or in other words, perform the RRM measurement. The method can reduce the scheduling restriction brought by the RRM measurement as much as possible, reduce the conflict between service data transmission and RRM measurement in the time domain, not only improve the service transmission performance, but also take into account the measurement performance.

[0247] Based on the above scheme, after the terminal side receives the third information, in the case of determining that the time interval between the starting moment of the RRM measurement and the time domain unit where the third information is located is greater than or equal to the second time period, that is, at least meeting the third condition, the terminal skips the RRM measurement according to the third information, and in the case of determining that the third condition is not met or at least meeting the fourth condition, the terminal performs the RRM measurement. The implementation can reduce the scheduling restriction brought by the RRM measurement as much as possible, improve the service transmission reliability, and at the same time, take into account the measurement performance. In particular, in the case of at least meeting the third condition, the terminal skips the RRM measurement in the inter-system scenario. The RRM measurement can be the RRM measurement of the first system, the RRM measurement of the second system, or the RRM measurement of other systems, which can greatly improve the transmission performance of service data. For example, the implementation can be applied to the non-standalone networking scenario of the NR system with more RRM measurements of the LTE system.

[0248] FIG. 10 is a schematic diagram of skipping RRM measurement provided by an embodiment of the present application. As shown in FIG. 10, the horizontal axis represents the time domain (for example, taking slot as an example), and the vertical axis represents the frequency domain (for example, taking resource block RB as an example). Exemplarily, assuming that the network side indicates that the reserved time length required for skipping the RRM measurement of the first system is 1 slot, and the reserved time length required for skipping the RRM measurement of the second system is 2 slots, the terminal can determine that the time length of the second time period is 2 slots, and the starting moment of the second time period is the first symbol after the symbol of the PDCCH carrying the first information. For example, there are three RRM measurements (in the order from left to right in time sequence: RRM measurement #1, RRM measurement #2, and RRM measurement #3), wherein the RRM measurement #1 is the RRM measurement of the LTE system, the RRM measurement #2 is the RRM measurement of the NR system, and the RRM measurement #3 is the RRM measurement of the NR system or the RRM measurement of the LTE system. The symbol of the PDCCH carrying the first information occupies the first three symbols of the slot.

[0249] Specifically, for RRM measurement #1, since the starting time of the first RRM measurement (i.e., RRM measurement #1) of the LTE system after the symbol where the third information is located and the time interval (e.g., time interval #1) between the first symbol after the symbol where the third information is located are greater than the second time period, i.e., the third condition is met, the terminal determines to skip the RRM measurement of the LTE system, i.e., to skip RRM measurement #1. For RRM measurement #2, since the starting time of the first RRM measurement (i.e., RRM measurement #2) of the LTE system after the symbol where the third information is located and the time interval (e.g., time interval #2) between the first symbol after the symbol where the third information is located are greater than the second time period, i.e., the third condition is met, the terminal determines to skip the RRM measurement of the NR system, i.e., to skip RRM measurement #2. For RRM measurement #3, since the starting time of the first RRM measurement (i.e., RRM measurement #3) of the LTE system after the symbol where the third information is located and the time interval (e.g., time interval #3) between the first symbol after the symbol where the third information is located are less than the second time period, i.e., the third condition is not met or the fourth condition is met, the terminal determines to skip the RRM measurement #3. In other words, no matter whether the RRM measurement #3 is an RRM measurement of the NR system, an RRM measurement of the NR system, or an RRM measurement of another system, as long as the second condition is met or the third condition is not met, the terminal performs the RRM measurement #3.

[0250] In this implementation, the RRM measurement (e.g., an RRM measurement of the NR system, or an RRM measurement of the NR system, or an RRM measurement of another system) is constrained by judging whether the third condition is met, i.e., the RRM measurement is reduced as much as possible, which not only improves the transmission performance of service data and enhances the overall experience of the terminal in service, but also improves the RRM measurement performance.

[0274] Fig. 12 is a structural schematic diagram of a terminal 2000 according to an embodiment of the present application. The terminal 2000 can correspond to the terminal shown in Fig. 1, and is configured to implement the operations of the terminal in the above embodiments. As shown in Fig. 12(a), the terminal 2000 includes one or more antennas 2010, a radio frequency processing system 2020, and a processor system 2030.

[0275] In the downlink or sidelink direction, the radio frequency processing system 2020 receives radio frequency signals through the antenna 2010, and sends the signals processed by radio frequency to the processor system 2030 for further processing. In the uplink or sidelink direction, the processor system 2030 processes the information at the terminal side, and sends the signals to the radio frequency processing system 2020. The radio frequency processing system 2020 processes the signals by radio frequency, and transmits the signals through the antenna 2010.

[0276] In one example, the radio frequency processing system 2020, as a communication interface for the terminal to communicate with the outside, can include a radio frequency front end 2021 (RFFE) and a radio frequency transceiver 2022 (RF transceiver). The RFFE 2021 is mainly used for one or more of shaping, passband selection, or gain processing of RF signals received by the antenna or RF signals to be sent through the antenna, and can include one or more of radio frequency switches, duplexers, filters, power amplifiers, antenna tuning, and low-noise amplifiers. The RFFE 2021 can be a circuit system composed of a plurality of discrete devices, or can be integrated and packaged in one or more chips. The radio frequency transceiver 2022 is used to process the RF signals received by the RFFE into baseband / intermediate frequency signals for further processing by the processor system 2030, and to process the baseband / intermediate frequency signals provided by the processor system 2030 into RF signals for sending to the RFFE 2021. The baseband / intermediate frequency signals transmitted between the radio frequency transceiver 2022 and the processor system 2030 can be digital signals or analog signals. The radio frequency transceiver 2022 can be implemented by one or more chips, which are usually referred to as radio frequency chips.

[0277] In one example, the processor system 2030 can include one or more processors for processing signals and executing one or more communication protocols. Optionally, the processor system 2030 can further include a memory 2036. In one example, the one or more processors include at least one baseband processor 2031 (also referred to as a modem processor).

[0278] In one example, the processor system 2030 can be packaged as one processor chip, such as a SoC chip or a SIP chip. In one example, the processor system 2030 can be a system composed of multiple chips, for example, the baseband processor 2031 can be packaged as a separate chip, or packaged as a chip with part or all of the circuitry of the radio frequency processing system.

[0279] In one example, the memory 2036 can be an on-chip memory, i.e., located on the chip of the processor system 2030. In one example, the memory 2060 can be an off-chip memory, i.e., located off the chip of the processor system 2030.

[0280] In one example, as shown in Figure 12(b), the baseband processor 2031 in the terminal 2000 provided by the embodiments of the present application can include one or more processor cores 20311 and interface circuitry 20314. The one or more processor cores 20311 are configured to process signals and execute one or more communication protocols. Optionally, the baseband processor 2031 can further include a memory 20312 configured to store at least part of corresponding computer program instructions and / or data. In one example, the one or more processor cores 20311 implement the relevant operations in the above method embodiments by executing the computer program instructions stored in the memory 20312. In the present application, the memory 20312 configured to store corresponding computer program instructions and / or data can mean that the memory 20312 is configured to store all corresponding computer program instructions and / or data for execution by the processor core 20311; or can mean that the memory 20312 is configured to store part of corresponding computer program instructions and / or data, which includes computer program instructions and / or data currently needed for execution by the processor core 20311, and the memory 20312 can store different parts of computer program instructions and / or data for execution by the processor core 20311 multiple times to implement the relevant operations in the above method embodiments. The interface circuitry 20314 serves as a communication interface to enable communication with other components, such as transmitting signals with the radio frequency processing system 2020, communicating with other subsystems and related components of the processor system 2030 through a bus, such as transmitting data control signals with the application processor 2032, and transmitting data or computer program instructions with the memory 2036 or the memory 2060. Optionally, to reduce the load of the processor core, a baseband signal processing circuit 20313 can be further provided to implement at least part of the processing of baseband signals, including one or more of demodulation, modulation, encoding or decoding of signals.

[0281] In one example, the communication device provided by the present application can be a terminal 2000, which includes a processor system 2030 and a communication module of a radio frequency processing system 2020, the processor system 2030, or a baseband processor 2031.

During terminal operation, the corresponding computer program instructions can be partially or entirely loaded onto a memory with faster transmission speed than the processor, such as at least part of the memory 2036 and / or the memory 20312 described above (which can be one or more of RAM, SRAM, DRAM, PCM, RERAM, MRAM, FRAM, cache, or register), for execution by the processor to implement the steps in the above method embodiments.
