Description

A communication method and related equipment

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on February 6, 2024, with application number 202410171427.1 and invention name “A communication method and related equipment”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communications, and in particular to a communication method and related equipment. Background Art

[0003] Wireless communication can be the transmission of information between two or more communication nodes without using conductors or cables, or over the air. For example, communication nodes include network devices and terminal devices. Generally, terminal devices can access network devices and receive scheduling and instruction information from them to achieve wireless communication.

[0004] Terminal devices configured with a low-power wake-up signal (LP-WUS) utilize a combination of a main receiver (MR) and a low-power receiver (LR). The MR is in ultra-deep sleep before being awakened by the LP-WUS. The benefits of LP-WUS come from monitoring the physical downlink control channel (PDCCH), replacing traditional paging occasions (POs), thus saving power.

[0005] However, before monitoring PO, the terminal device must perform measurements and cell reselection. If it still uses traditional measurements based on the system synchronization block (SSB), the terminal must also enable or partially enable MR, which significantly affects the gain of WUS. Summary of the Invention

[0006] The present application provides a communication method and related equipment. By sending a neighboring cell WUS configuration to a terminal device, the terminal device can perform neighboring cell measurement through the first indication information in the LR state to achieve cell reselection, switching measurement and other operations, thereby reducing the WUS gain impact caused by turning on MR.

[0007] The first aspect of the present application provides a communication method, which is executed by a network device, or the method is executed by some components in the network device (such as a processor, chip or chip system, etc.), or the method can also be implemented by a logic module or software that can realize all or part of the network device functions. In the first aspect and its possible implementation, the method is described as being executed by a network device. In this method, the network device determines a first indication information, and the first indication information is used at least to indicate the time domain resources of the wake-up signal WUS of the neighboring area of ​​the terminal device, and the first indication information is used for the terminal device to perform neighboring area measurement; the network device sends the first indication information.

[0008] Based on the above solution, the network device configures the first indication information for the terminal device to indicate the WUS configuration of the neighboring cell, so that the terminal device can perform neighboring cell measurements through the neighboring cell WUS. The terminal device can then perform neighboring cell measurements using the first indication information in the LR state to implement operations such as cell reselection and handover measurement, thereby reducing the impact of WUS gain caused by turning on MR.

[0009] Optionally, in a possible implementation of the first aspect, the above steps also include: determining the level of the first receiver of the terminal device, different levels corresponding to different correction values; determining the first indication information, including: determining the first indication information based on the level.

[0010] In this possible implementation, the network device can also determine the correction value indicated by the first indication information based on the LR level of the terminal device, so that the neighboring cell WUS configuration can be performed for terminal devices of different LR levels in a more fine-grained manner, thereby improving the accuracy of subsequent WUS measurement values ​​adjusted in the LR state based on the correction value.

[0011] Optionally, in a possible implementation of the first aspect, before the above step: determining the level of the first receiver of the terminal device, the method also includes: receiving second indication information, the second indication information being used to indicate the level of the first receiver of the terminal device; and determining the level based on the second indication information.

[0012] In this possible implementation method, the network device can specifically configure a corresponding correction value for the terminal device through the LR level of the terminal device through the second indication information reported by the terminal device, which can not only improve the scheduling flexibility of the terminal device, but also improve the accuracy of the subsequent WUS measurement value adjusted in the LR state based on the correction value.

[0013] The second aspect of the present application provides a communication method, which is executed by a terminal device, or the method is executed by some components in the terminal device (such as a processor, chip or chip system, etc.), or the method can also be implemented by a logic module or software that can realize all or part of the terminal device functions.

In this method, the terminal device receives first indication information, and the first indication information includes at least: the time domain resources of the wake-up signal WUS of the neighboring area of ​​the terminal device; the terminal device performs neighboring area measurement based on the first indication information.

[0014] In this possible implementation, the terminal device can perform neighboring cell measurement using the first indication information. Furthermore, the terminal device can perform neighboring cell measurement using the first indication information in the LR state to implement operations such as cell reselection and handover measurement, thereby reducing the impact of WUS gain caused by turning on MR.

[0015] Optionally, in a possible implementation of the second aspect, the above steps also include: sending second indication information, the second indication information is used to indicate the level of the first receiver of the terminal device, different levels correspond to different correction values, and the second indication information is related to the first indication information.

[0016] In this possible implementation, the terminal device can report the level of the first receiver so that the network device can configure a correction value that is more suitable for the terminal device. This can not only improve the scheduling flexibility of the terminal device, but also improve the accuracy of subsequent WUS measurement values ​​adjusted in the LR state based on the correction value.

[0017] Optionally, in a possible implementation of the first aspect or the second aspect, the above-mentioned terminal device includes a first receiver and a second receiver, and the operating power of the first receiver is less than the operating power of the second receiver; the first indication information is also used to indicate a correction value, and the correction value is used to determine the second measurement value of the second receiver corresponding to the first measurement value of the first receiver, and the second measurement value is used for cell reselection or switching measurement of the terminal device.

[0018] In this possible implementation, the correction value is indicated by the first indication information, so that the terminal device can estimate the neighboring cell measurement result of the MR in the LR state, and can reduce the WUS gain impact caused by turning on the MR.

[0019] Optionally, in a possible implementation of the first aspect or the second aspect, the above-mentioned first indication information is also used to indicate the applicable scope of the correction value, and the applicable scope includes any one of the following: all neighboring areas of the terminal device and the same-frequency neighboring areas of the terminal device.

[0021] Optionally, in a possible implementation of the first aspect or the second aspect, different neighboring areas of the terminal device correspond to different correction values.

[0022] In this possible implementation, different neighboring cells correspond to different correction values, thereby facilitating flexible scheduling of terminal devices to perform WUS measurements in each neighboring cell.

[0023] Optionally, in a possible implementation of the first aspect or the second aspect, when the terminal device is in an idle state or an inactive state, the first indication information is used for the terminal device to perform cell reselection.

[0024] In this possible implementation, the terminal device may use the LR and the first indication information to implement cell reselection, so as to reduce the WUS gain impact caused by turning on the MR.

[0060] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0061] First, some of the terms used in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0062] 1. Radio resource control (RRC) status

[0063] In 4G and 5G cellular communication systems, the network provides services to terminals in cells. After selecting a cell, a terminal device resides in that cell, ready to initiate uplink services and receive downlink services at any time. From the perspective of the radio access network, a terminal device in a cell has three different RRC states: RRC connected (RRC_Connected), RRC idle (RRC_IDLE), and RRC inactive (RRC_INACTIVE).

[0064] RRC connected state: The terminal device has established an RRC connection with the network, enabling data transmission. The RRC connected state can also be referred to as the connected state. In this document, "connected state" and "RRC connected state" are the same concept and can be referred to interchangeably.

[0065] For example, the terminal device responds to network paging or actively initiates random access, establishes an RRC connection with the network device, and transmits services. For the network device and the core network device, the terminal device is visible.

[0066] RRC Idle State: The terminal device has not established an RRC connection with the network, and the network equipment has not stored the context of the terminal device. If the terminal device needs to enter the RRC Connected State from the RRC Idle State, it needs to initiate the RRC connection establishment process. The RRC Idle State can also be simply referred to as the Idle State. In this article, "Idle State" and "RRC Idle State" are the same concept and can be referred to interchangeably.

[0067] For example, a terminal device resides in a cell and has no ongoing services. It is invisible to network devices and core network devices. The terminal device monitors system broadcasts and paging.

[0068] System broadcast: Ensures that the latest system information is saved at all times to monitor paging (triggering cell access for uplink services) and initiate random access (active access to the network for uplink services) as needed.

[0069] Paging: includes network downlink service triggering, system message changes, multicast service start indication, etc.

[0070] RRC inactive state: The terminal device has previously entered the RRC connected state, and then the base station released the RRC connection, but the base station saved the context of the terminal device. If the terminal device needs to enter the RRC connected state again from the RRC inactive state, it is necessary to initiate an RRC recovery process (or called an RRC connection recovery process). Compared with the RRC establishment process, the RRC recovery process has a shorter delay and lower signaling overhead. However, the base station needs to save the context of the terminal device, which will occupy the storage overhead of the base station. The RRC inactive state can also be referred to as the inactive state. In this article, "deactivated state", "deactivated state", "inactive state", "RRC inactive state" and "RRC deactivated state" are the same concept, and these names can be interchanged.

[0071] For example, if a terminal device is stationed in a cell with no ongoing services, the network device typically configures the terminal device to enter the connected state when releasing the connected state. This state is invisible to the network device, but the core network device still considers the terminal device to be in the connected state. The terminal device behaves similarly to the idle state, primarily listening for paging and system messages. The main difference is that paging is primarily Radio Access Network (RAN) paging sent by the network device.

[0072] 2. Configuration and pre-configuration

[0073] In this application, configuration and pre-configuration are used simultaneously. Configuration refers to the network device / server sending some parameter configuration information or parameter values ​​to the terminal through messages or signaling, so that the terminal can determine the communication parameters or resources during transmission based on these values ​​or information. Pre-configuration is similar to configuration and can be parameter information or parameter values ​​pre-negotiated between the network device / server and the terminal device, parameter information or parameter values ​​used by the base station / network device or terminal device as specified in the standard protocol, or parameter information or parameter values ​​pre-stored in the base station / server or terminal device. This application does not limit this.

[0074] Furthermore, these values ​​and parameters can be changed or updated.

[0075] 3. In this application, "used for indication" can include direct indication and indirect indication. When describing that a certain indication information is used to indicate A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.

[0076] In this application, the information indicated by the indication information is referred to as the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated. For example, it can be implemented by direct indication, such as by indicating the information to be indicated itself or the index of the information to be indicated. It can also be implemented by indirectly indicating other information, wherein there is an association between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can also be achieved with the help of the arrangement order of each information agreed in advance (for example, stipulated in the protocol), thereby reducing the indication overhead to a certain extent.

[0077] The information to be indicated can be sent as a whole, or divided into multiple sub-information and sent separately, and the sending period and / or sending time of these sub-information can be the same or different. The specific sending method is not limited in this application. Among them, the sending period and / or sending time of these sub-information can be pre-defined, for example, pre-defined according to the protocol, or configured by the transmitting device by sending configuration information to the receiving device. Among them, the configuration information can, for example, but not limited to, include one or a combination of at least two of RRC signaling, medium access control (MAC) layer signaling and physical layer signaling. Among them, MAC layer signaling, for example, includes MAC CE; physical layer signaling, for example, includes downlink control information (DCI).

[0078] 4. "Sending" and "receiving" in the embodiments of this application indicate the direction of signal transmission. In this application, when entity A sends information to entity B, A may send it directly to B or indirectly to B through another entity. Similarly, when entity B receives information from entity A, entity B may directly receive the information sent by entity A or indirectly receive the information sent by entity A through another entity. Entities A and B herein may be RAN nodes or terminals, or modules within a RAN node or terminal. The sending and receiving of information may be information exchange between a RAN node and a terminal, for example, between a base station and a terminal; between two RAN nodes, for example, between a CU and a DU; or between different modules within a device, for example, between a terminal chip and other modules in the terminal, or between a base station chip and other modules within the base station. "Sending" may also be understood as the "output" of a chip interface, for example, the output from a baseband chip to a radio frequency chip, and "receiving" may also be understood as the "input" of a chip interface.

[0079] 5. The terms "system" and "network" in the embodiments of the present application can be used interchangeably. "At least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, "at least one of A, B and C" includes A, B, C, AB, AC, BC or ABC. And, unless otherwise specified, the ordinal numbers such as "first" and "second" mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the order, timing, priority or importance of multiple objects.

[0080] Please refer to Figure 1A, which is a schematic diagram of the architecture of a communication system 1000 used in an embodiment of the present application. As shown in Figure 1A, the communication system includes a radio access network (RAN) 100 and a core network 200. Optionally, the communication system 1000 may also include the Internet 300. The RAN 100 includes at least one RAN node (such as 110a and 110b in Figure 1A, collectively referred to as 110), and may also include at least one terminal (such as 120a-120j in Figure 1A, collectively referred to as 120). The RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 1A). The terminal 120 is connected to the RAN node 110 via a wireless connection, and the RAN node 110 is connected to the core network 200 via a wireless or wired connection. The core network equipment in the core network 200 and the RAN node 110 in the RAN 100 can be independent and different physical devices, or they can be the same physical device that integrates the logical functions of the core network equipment and the logical functions of the RAN node. Terminals and RAN nodes may be connected to each other via wired or wireless means.

[0081] The RAN 100 may be an Evolved Universal Terrestrial Radio Access (E-UTRA) system, a NR system, or a future radio access system defined in 3GPP. The RAN 100 may also include two or more of the aforementioned different radio access systems. The RAN 100 may also be an open RAN (O-RAN).

[0082] A RAN node, also known as a radio access network device, RAN entity, or access node, is used to help terminals access a communication system wirelessly. In one application scenario, a RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a fifth-generation (5G) mobile communication system, a next-generation base station in a sixth-generation (6G) mobile communication system, or a base station in a future mobile communication system. A RAN node can be a macro base station (such as 110a in Figure 1A), a micro base station, an indoor station (such as 110b in Figure 1A), a relay node, or a donor node.

[0083] In another application scenario, multiple RAN nodes can collaborate to help terminals achieve wireless access, with different RAN nodes implementing portions of the base station's functions. For example, a RAN node can be a centralized unit (CU), a distributed unit (DU), or a radio unit (RU). The CU implements the base station's radio resource control protocol and packet data convergence protocol (PDCP) functions, as well as the service data adaptation protocol (SDAP) functions. The DU implements the base station's radio link control layer and medium access control (MAC) layer functions, as well as some or all of the physical layer functions. For detailed descriptions of each of the above protocol layers, please refer to the relevant 3GPP technical specifications. The RU can be used to implement the transmission and reception of radio frequency signals. The CU and DU can be two independent RAN nodes, or they can be integrated into the same RAN node, such as in a baseband unit (BBU). The RU can be included in radio frequency equipment, such as a remote radio unit (RRU) or an active antenna unit (AAU). The CU can be further divided into two types of RAN nodes: CU-control plane and CU-user plane.

[0084] In different systems, RAN nodes may have different names. For example, in an O-RAN system, the CU may be called an open CU (O-CU), the DU may be called an open DU (O-DU), and the RU may be called an open RU (O-RU). The RAN nodes in the embodiments of the present application may be implemented by software modules, hardware modules, or a combination of software modules and hardware modules. For example, the RAN node may be a server loaded with the corresponding software module. The embodiments of the present application do not limit the specific technology and specific device form used by the RAN node.

[0085] In addition, a RAN node can also be referred to as a network device. A network device is a device deployed in a radio access network to provide wireless communication functions for terminal devices. Network devices may include various forms of macro base stations, micro base stations (also known as small stations), relay stations, access points, etc. In systems using different radio access technologies, the names of network devices may be different, such as eNB or eNodeB (evolutionary NodeB) in Long Term Evolution (LTE). A network device may also be a wireless controller in a cloud radio access network (CRAN) scenario. A network device may also be a base station device in a future 5G network or a network device in a future evolved PLMN network. A network device may also be a wearable device or an in-vehicle device. A network device may also be a transmission and reception point (TRP). In addition, in a network structure, a network device may include a centralized unit (CU) node, a distributed unit (DU) node, or a RAN device including a CU node and a DU node. For ease of description, the following description uses a base station as an example of a RAN node.

[0086] A terminal is a device with wireless transceiver capabilities that can send signals to a base station or receive signals from a base station. A terminal may also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, smart city, etc. A terminal can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, wearable device, vehicle, airplane, ship, robot, robotic arm, smart home device, etc. The embodiments of this application do not limit the specific technology and specific device form adopted by the terminal.

[0087] Base stations and terminals can be fixed or mobile. They can be deployed on land, indoors or outdoors, handheld or vehicle-mounted; on water; or on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of base stations and terminals.

[0088] The roles of base stations and terminals can be relative. For example, the helicopter or drone 120i in Figure 1A can be configured as a mobile base station. To terminals 120j accessing the wireless access network 100 via 120i, terminal 120i is a base station. However, to base station 110a, 120i is a terminal, meaning that communication between 110a and 120i occurs via a wireless air interface protocol. Of course, communication between 110a and 120i can also occur via a base station-to-base station interface protocol. In this case, 120i is also a base station relative to 110a. Therefore, base stations and terminals can be collectively referred to as communication devices. 110a and 110b in Figure 1A can be referred to as communication devices with base station functionality, while 120a-120j in Figure 1A can be referred to as communication devices with terminal functionality.

[0089] Communication between base stations and terminals, between base stations, and between terminals can be carried out through authorized spectrum, unauthorized spectrum, or both; communication can be carried out through spectrum below 6 gigahertz (GHz), spectrum above 6 GHz, or spectrum below 6 GHz and spectrum above 6 GHz. The embodiments of the present application do not limit the spectrum resources used for wireless communication.

[0090] In the embodiments of the present application, the functions of the base station may also be performed by a module (such as a chip) in the base station, or by a control subsystem that includes the base station functions. The control subsystem that includes the base station functions here may be a control center in the above-mentioned application scenarios such as smart grid, industrial control, smart transportation, and smart city. The functions of the terminal may also be performed by a module (such as a chip or modem) in the terminal, or by a device that includes the terminal functions.

[0091] It can be understood that the RAN 100 described above includes at least one RAN node (such as 110 a and 110 b in FIG. 1A , collectively referred to as 110 ), and may also include at least one terminal (such as 120 a - 120 j in FIG. 1A , collectively referred to as 120 ).

[0092] In one possible implementation, the communication system shown in FIG1A may also be as shown in FIG1B , that is, including a RAN node 110 and multiple terminals (such as 120A and 120B in FIG1B ). In this case, a single RAN node can transmit data or control signaling to a single terminal or multiple terminals.

[0093] In another possible implementation, the communication system shown in FIG1A may also be shown in FIG1C , that is, include multiple RAN nodes (such as 110A, 110B, and 110C in FIG1C ) 110 and a terminal 120. In this case, multiple RAN nodes may also simultaneously transmit data or control signaling for a single terminal.

[0094] Currently, terminal devices configured with LP-WUS use a combination of MR and LR. MR is in a deep sleep state before being awakened by LP-WUS. The benefits of LP-WUS come from PDCCH monitoring, which replaces traditional PO, saving power. However, before monitoring PO, terminal devices must perform measurements and cell reselection decisions. If traditional measurements based on SSB are still used, the terminal must also enable or partially enable MR, significantly impacting the benefits of WUS.

[0095] To address the above technical issues, embodiments of the present application provide a communication method and related devices. A network device configures a terminal device with first indication information indicating the WUS configuration of a neighboring cell, enabling the terminal device to perform neighboring cell measurements using the neighboring cell WUS. Furthermore, neighboring cell measurements can be performed using the first indication information in the LR state to implement operations such as cell reselection and handover measurements, thereby reducing the impact of WUS gain caused by enabling MR.

[0096] Please refer to Figure 2, which is a flow chart of a communication method provided in an embodiment of the present application. The method may include steps 201 to 203. Steps 201 to 203 can be performed by a communication device (network device and / or terminal device), or can be performed by some components in the communication device (such as a processor, chip or chip system, etc.), or can be implemented by a logic module or software that can realize all or part of the functions of the communication device. The following description is taken as an example of execution by a network device and a terminal device. The processing performed by a single execution subject in steps 201 to 203 can also be divided into executions by multiple execution subjects, and these execution subjects can be logically and / or physically separated. For example, in the case where the communication device is a network device, the processing performed by the communication device can be divided into executions by at least one of the CU, DU and RU. Steps 201 to 203 are described in detail below.

[0097] Step 201: The network device determines first indication information.

[0098] The network device determines first indication information, which is used to indicate the time domain resource of the wake-up signal WUS of the neighboring cell of the terminal device, and the first indication information is used by the terminal device to perform neighboring cell measurement. Alternatively, it can be understood that the WUS of the neighboring cell is used by the terminal device to perform neighboring cell measurement.

[0099] Among them, the first indication information can also be understood as being used to indicate the WUS configuration of the neighboring cell, mainly so that the terminal device can receive the WUS of the neighboring cell, so that the neighboring cell measurement can be performed based on the WUS of the neighboring cell.

[0100] A neighboring cell can also be understood as an adjacent cell, or as a cell adjacent to the cell where the terminal device is located. For example, as shown in Figure 3, the neighboring cells of the cell where the terminal device is located include neighboring cell 1 and neighboring cell 2. It will be understood that Figure 2 is only an example of neighboring cells, and in actual applications, the number of neighboring cells of the terminal device can be greater.

[0101] Neighboring cell measurement mainly refers to measuring one or more of the neighboring cell's Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), Received Signal Strength Indicator (RSSI), or Signal to Interference Noise Ratio (SINR).

[0102] Optionally, the first indication information is further used to indicate at least one of the following: frequency domain resources of the neighboring cell WUS, code domain resources of the neighboring cell WUS (for example, a sequence or sequence range used by the neighboring cell WUS), a correction value, etc. When the first indication information is also used to indicate the correction value, the first indication information can also be understood as being used to instruct the terminal device to use a lower-power LR for neighboring cell measurement.

[0103] The terminal device includes a first receiver and a second receiver, and the operating power of the first receiver is less than the operating power of the second receiver. The first receiver can also be called an auxiliary link receiver or LR, and the second receiver can also be called an MR or a high-power receiver. The correction value is used to determine the second measurement value of the second receiver corresponding to the first measurement value of the first receiver. Alternatively, it can be understood that the correction value is used to adjust the first measurement value to obtain the second measurement value. The second measurement value is used for cell reselection or handover measurement of the terminal device. The correction value can also be called an LR correction value, offset or offset coefficient, etc. Alternatively, it can be understood that the terminal device can obtain the MR measurement value through the LR measurement value and the correction value without turning on the MR, thereby reducing the power consumption of the terminal device when turning on the MR.

[0104] Optionally, in order to improve the correction effect, the configuration information may further indicate the applicable scope of the correction value. The applicable scope includes any one of the following: all neighboring areas of the terminal device, the same-frequency neighboring areas of the terminal device, the specific neighboring areas of the terminal device, etc. Different neighboring areas of the terminal device correspond to different correction values. Alternatively, it can be understood that the first indication information indicates that the LR correction value used by the terminal device when performing the neighboring area WUS measurement can be shared by all neighboring areas, shared by all same-frequency neighboring areas, or used separately by each cell.

[0105] Optionally, to schedule each terminal device at a finer granularity, the network device may further determine the level of the first receiver (or LR level) of each terminal device and determine the first indication information based on the level, with different levels corresponding to different correction values. Alternatively, the correction values ​​may be different for terminal devices of different LR levels.

[0106] Furthermore, the network device determines the LR level of each terminal device, which may be the LR level of each terminal device actively configured by the network device, or the LR level reported by each terminal device, etc., which is not limited here.

[0107] For example, the network device receives second indication information reported by the terminal device, where the second indication information is used to indicate the level of the first receiver of the terminal device.

[0108] It can be understood that the higher the LR level, the higher the correction value, or the higher the LR level, the lower the correction value, or the lower the LR level, the higher the correction value, or the lower the LR level, the lower the correction value, etc. It can be set according to actual needs and is not limited here.

[0109] For example, the relationship between the LR level and the correction value of each terminal device may be shown in Table 1:

[0110] Table 1

[0111] Among them, when the LR level is 1, the correction value is a; when the LR level is 2, the correction value is b; when the LR level is 3, the correction value is c; and when the LR level is 4, the correction value is d. It is understood that Table 1 is only an example of the relationship between LR levels and correction values. The specific relationship can be set according to actual needs and is not limited here.

[0112] The first indication information in the embodiment of the present application can also be understood as the configuration information of the terminal device, that is, this step can be understood as the process of the network device determining the configuration information for the terminal device.

[0113] In addition, the specific function of the first indication information may vary based on the different states of the terminal device. For example, when the terminal device is in an idle state or an inactive state, the first indication information may be used by the terminal device to perform cell reselection. For another example, when the terminal device is in a connected state, the first indication information may be used by the terminal device to perform handover measurements, etc. Specific limitations are not provided here.

[0114] For example, the first indication information is used in an idle state measurement scenario for cell reselection. Specifically, the network device configures the measurement range (cell, frequency, etc.) and trigger conditions (such as the serving cell signal quality falling below a threshold) in the broadcast. If the conditions are met, the terminal initiates neighboring cell measurement. The terminal does not need to report the measurement results, and the network device is unaware of them. Once the terminal selects a cell, it can switch to the neighboring cell.

[0115] For example, in a connected measurement scenario, the network device unicasts the configuration of the terminal's measurement range and trigger conditions. After the terminal triggers the measurement, it performs the required measurements and reports the results to the network device. Based on the results reported by the terminal, the network device decides whether to handover the terminal to another cell and which cell to handover to. The network device then sends a clear handover command to the terminal, including the target cell's identifier and configuration. The terminal then accesses the target cell.

[0116] Optionally, the indication information is carried on a control channel. Specifically, the indication information may be at least one of the following: RRC signaling, MAC layer signaling, or physical layer signaling. MAC layer signaling may include, for example, MAC CE; and physical layer signaling may include, for example, DCI.

[0117] Step 202: The network device sends first indication information to the terminal device.

[0118] After determining the first indication information, the network device sends the first indication information to the terminal device. Correspondingly, the terminal device receives the first indication information sent by the network device.

[0119] Step 203: The terminal device performs neighboring cell measurement based on the first indication information.

[0120] After the terminal device receives the first indication information sent by the network device, it can perform neighboring area measurement based on the first indication information.

[0121] Optionally, after the terminal device obtains the first indication information, it can receive the neighboring cell WUS based on the neighboring cell WUS configuration indicated by the indication information, so that the neighboring cell WUS can be used to perform neighboring cell measurements, etc.

[0122] Optionally, the configuration information also indicates a correction value and an applicable scope of the correction value. For example, the applicable scope of the correction value is all neighboring areas of the terminal device. The terminal device can use the same correction value to correct the WUS measurement results of all neighboring areas. For another example, the applicable scope of the correction value is the same-frequency neighboring area of ​​the terminal device. The terminal device can use the same correction value to correct the WUS measurement results of all same-frequency neighboring areas. For another example, the applicable scope of the correction value is a specific neighboring area of ​​the terminal device. The terminal device can use the correction value to correct the WUS measurement result of a specific neighboring area. The terminal device can use the corrected WUS measurement result to make decisions on cell reselection, switching measurements, etc.

[0123] In this case, the terminal device can use the WUS measurement result of the LR to estimate the WUS measurement result of the MR, thereby not using a high-power receiver (i.e., the MR) for measurement to reduce power consumption. That is, the terminal device uses the LR to perform a WUS measurement of the neighboring area to obtain a WUS measurement result (i.e., a first measurement value), and adjusts the WUS measurement result by a correction value (for example, adding the correction value, multiplying the correction value, or dividing the correction value) to estimate the WUS measurement result of the MR (i.e., a second measurement value).

[0124] For example, assuming that the first measurement value is recorded as a, the correction value is recorded as b, and the second measurement value is recorded as c, the terminal device obtains a by measuring the neighboring cell through LR, and obtains c by combining the correction value b indicated in the configuration information with a.

[0125] Similarly, the specific function of the first indication information may vary based on the different states of the terminal device. For example, when the terminal device is in an idle state or an inactive state, the terminal device may perform cell reselection based on the first indication information. For another example, when the terminal device is in a connected state, the terminal device may perform handover measurements based on the first indication information. Specific limitations are not set forth herein.

[0126] In an embodiment of the present application, the network device configures the terminal device with first indication information indicating the WUS configuration of the neighboring cell, so that the terminal device can perform neighboring cell measurement through the neighboring cell WUS. Furthermore, the neighboring cell measurement can be performed in the LR state through the first indication information to implement operations such as cell reselection and handover measurement, thereby reducing the WUS gain impact caused by turning on MR.
