Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to a communication method and related equipment. Background Art

[0002] Wireless communication can be a transmission communication between two or more communication nodes that is not transmitted through conductors or cables or is transmitted through air interfaces. For example, the communication nodes include network devices and terminal devices. Generally, the terminal device can access the network device and receive scheduling and instruction information from the network device to achieve wireless communication.

[0003] The terminal device under the low power wake up signal (LP-WUS) configuration adopts the main link receiver (MR) and low power receiver (LR) combined mode. MR is in ultra-deep sleep state before being awakened by LP-WUS. The gain of LP-WUS comes from the monitoring of the physical downlink control channel (PDCCH) instead of the traditional paging occasion (PO), saving power consumption.

[0004] However, before monitoring PO, the terminal device still needs to perform measurement, cell reselection and other operations. If it is still based on the traditional measurement of system synchronization block (SSB), the terminal also needs to turn on or partially turn on MR, which has a great impact on the gain of WUS. Summary of the invention

[0005] 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 the MR.

[0006] In a first aspect, 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, a chip or a 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 the method, the network device determines first indication information, and the first indication information is at least used 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.

[0007] 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 area, so that the terminal device can perform neighboring area measurement through the neighboring area WUS. Then, the terminal device can perform neighboring area measurement through the first indication information in the LR state to implement operations such as cell reselection and switching measurement, thereby reducing the WUS gain impact caused by turning on MR.

[0008] Optionally, in a possible implementation of the first aspect, the above steps also include: determining a 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.

[0009] 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.

[0010] 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.

[0011] In this possible implementation, 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.

In this method, the terminal device receives first indication information, and the first indication information includes at least: the time domain resource 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.

[0013] In this possible implementation, the terminal device can perform neighboring cell measurement through the first indication information. Then, the terminal device can perform neighboring cell measurement through the first indication information in the LR state to implement operations such as cell reselection and handover measurement, thereby reducing the WUS gain impact caused by turning on MR.

[0015] 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 adjustments to the WUS measurement value in the LR state based on the correction value.

[0018] 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.

[0022] Optionally, in a possible implementation manner 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.

[0059] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0060] First, some terms in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0061] 1. Radio resource control (RRC) status

[0062] In 4G and 5G cellular communication systems, the network provides services to terminals in cells. After the terminal device selects a cell, it stays in the cell and can initiate uplink services at any time and is ready to receive downlink services from the network at any time. From the perspective of the wireless access network, the terminal device has three different RRC states in a cell: RRC connected state (RRC_Connected), RRC idle state (RRC_IDLE), and RRC inactive state (RRC_INACTIVE).

[0063] RRC connection state: The terminal device has established an RRC connection with the network and can transmit data. The RRC connection state can also be referred to as the connection state. In this article, "connection state" and "RRC connection state" are the same concept and the two names can be interchanged.

[0064] 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.

[0065] RRC idle state: The terminal device has not established an RRC connection with the network, and the network device 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 referred to as the idle state. In this article, "idle state" and "RRC idle state" are the same concept and the two names can be interchanged.

[0066] For example, when a terminal device resides in a cell and has no ongoing services, the terminal device is invisible to network devices and core network devices. The terminal device monitors system broadcasts and paging.

[0067] System broadcast: ensure that the latest system information is always saved in order to monitor paging (triggering cell access for uplink services) and initiate random access (active access to the network for uplink services) as needed at any time

[0068] Paging: includes network downlink service triggering, or system message changes, multicast service start indication, etc.

[0069] 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 the RRC recovery process (or called the RRC connection recovery process). Compared with the RRC establishment process, the RRC recovery process has a shorter delay and less 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.

[0070] For example, when a terminal device resides in a cell and has no ongoing services, the network device usually configures the terminal device to enter the connected state when releasing the connected state. This is invisible to the network device, and the core network device still considers the terminal device to be in the connected state. The behavior of the terminal device is similar to that in the idle state, mainly monitoring paging and system messages. The main difference is that the paging is mainly the Radio Access Network (RAN) paging sent by the network device.

[0071] 2. Configuration and pre-configuration

[0072] In this application, configuration and pre-configuration are used at the same time. 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, or parameter information or parameter values ​​used by the base station / network device or terminal device specified by 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.

[0073] Furthermore, these values ​​and parameters can be changed or updated.

[0074] 3. In this application, "used for indication" may include being used for direct indication and being used for 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.

[0075] 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, specified by the protocol), thereby reducing the indication overhead to a certain extent.

[0076] 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 can be configured by the transmitting device by sending configuration information to the receiving device. Among them, the configuration information can include, for example, but not limited to, 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).

[0077] 4. "Send" and "receive" in the embodiments of the present application indicate the direction of signal transmission. In the present application, entity A sends information to entity B, which may be A directly sending to B, or A indirectly sending to B through other entities. Similarly, entity B receives information from entity A, which may be entity B directly receiving information sent by entity A, or entity B indirectly receiving information sent by entity A through other entities. Entities A and B here may be RAN nodes or terminals, or modules inside RAN nodes or terminals. The sending and receiving of information may be information interaction between a RAN node and a terminal, for example, information interaction between a base station and a terminal; the sending and receiving of information may also be information interaction between two RAN nodes, for example, information interaction between a CU and a DU; the sending and receiving of information may also be information interaction between different modules inside a device, for example, information interaction between a terminal chip and other modules of the terminal, or information interaction between a base station chip and other modules in the base station. "Send" may also be understood as the "output" of a chip interface, for example, the output of a baseband chip to a radio frequency chip, and "receive" may also be understood as the "input" of a chip interface.

[0078] 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 represent: the existence of A alone, the existence of A and B at the same time, and the existence of B alone, where A and B can be singular or plural. The character " / " generally indicates that the objects associated with each other 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 items 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.

[0079] See also Figure 1A , is a schematic diagram of the architecture of a communication system 1000 used in an embodiment of the present application. Figure 1A As shown, 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 Figure 1A 110a and 110b in the figure, collectively referred to as 110), and may also include at least one terminal (such as Figure 1A RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment ( Figure 1A (not shown in the figure). The terminal 120 is connected to the RAN node 110 by wireless means, and the RAN node 110 is connected to the core network 200 by wireless or wired means. The core network device in the core network 200 and the RAN node 110 in the RAN 100 may be independent and different physical devices, or may be the same physical device that integrates the logical functions of the core network device and the logical functions of the RAN node. Terminals and terminals and RAN nodes and RAN nodes may be connected to each other by wired or wireless means.

[0080] RAN 100 may be an evolved universal terrestrial radio access (E-UTRA) system, an NR system, or a future radio access system defined in 3GPP. RAN 100 may also include two or more of the above different radio access systems. RAN 100 may also be an open RAN (O-RAN).

[0081] RAN node, also known as radio access network equipment, RAN entity or access node, is used to help terminals access the communication system wirelessly. In one application scenario, the RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB) in the fifth generation (5G) mobile communication system, a next generation NodeB in the sixth generation (6G) mobile communication system, or a base station in a future mobile communication system. RAN nodes can be macro base stations (such as Figure 1A 110a), or a micro base station or an indoor station (such as Figure 1A 110b) in the figure, it can also be a relay node or a donor node.

[0082] In another application scenario, the cooperation of multiple RAN nodes can be used to help the terminal achieve wireless access, and different RAN nodes respectively implement part of the functions of the base station. For example, the RAN node can be a centralized unit (CU), a distributed unit (DU) or a radio unit (RU). The CU here completes the functions of the radio resource control protocol and the packet data convergence protocol (PDCP) of the base station, and can also complete the function of the service data adaptation protocol (SDAP); the DU completes the functions of the radio link control layer and the medium access control (MAC) layer of the base station, and can also complete the functions of part of the physical layer or all of the physical layer. For the specific description of the above-mentioned various protocol layers, please refer to the relevant technical specifications of 3GPP. RU can be used to implement the transceiver function of radio frequency signals. CU and DU can be two independent RAN nodes, or they can be integrated in the same RAN node, such as integrated in a baseband unit (BBU). RU can be included in a radio frequency device, 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.

[0083] In different systems, RAN nodes may have different names. For example, in an O-RAN system, CU may be called an open CU (open CU, O-CU), DU may be called an open DU (open DU, O-DU), and RU may be called an open RU (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 corresponding software modules. The embodiments of the present application do not limit the specific technology and specific device form adopted by the RAN node.

[0084] In addition, a RAN node may also be referred to as a network device, which is a device deployed in a wireless 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 wireless access technologies, the names of network devices may be different, such as eNB or eNodeB (evolutional NodeB) in Long Term Evolution (LTE). The network device may also be a wireless controller in a cloud radio access network (CRAN) scenario. The network device may also be a base station device in a future 5G network or a network device in a future evolved PLMN network. The network device may also be a wearable device or a vehicle-mounted device. The network device may also be a transmission and reception point (TRP). In addition, in a network structure, the 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, a base station is used as an example of a RAN node for description below.

[0085] A terminal is a device with wireless transceiver function, which can send signals to a base station or receive signals from a base station. A terminal can also be called a terminal device, user equipment (UE), a mobile station, a mobile terminal, etc. The terminal can be widely used in various scenarios, for example, device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, automatic driving, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, an airplane, a ship, a robot, a mechanical arm, a smart home device, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal.

[0086] Base stations and terminals can be fixed or movable. Base stations and terminals can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on the water surface; they can also be deployed on airplanes, balloons, and artificial satellites. The embodiments of this application do not limit the application scenarios of base stations and terminals.

[0087] The roles of the base station and the terminal can be relative, for example, Figure 1A The helicopter or drone 120i in the figure can be configured as a mobile base station. For the terminal 120j that accesses the wireless access network 100 through 120i, the terminal 120i is a base station; but for the base station 110a, 120i is a terminal, that is, 110a and 120i communicate through the wireless air interface protocol. Of course, 110a and 120i can also communicate through the interface protocol between base stations. In this case, relative to 110a, 120i is also a base station. Therefore, base stations and terminals can be collectively referred to as communication devices. Figure 1A 110a and 110b in the figure may be referred to as communication devices having base station functions. Figure 1A 120a-120j in the figure can be called communication devices with terminal functions.

[0088] Base stations and terminals, base stations and base stations, and terminals and terminals can communicate through authorized spectrum, unauthorized spectrum, or both; they can communicate 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.

[0089] 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 including the base station function. The control subsystem including the base station function 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 a modem) in the terminal, or by a device including the terminal function.

[0090] It can be understood that the RAN 100 has been described above as including at least one RAN node (such as Figure 1A 110a and 110b in the figure, collectively referred to as 110), and may also include at least one terminal (such as Figure 1A 120a-120j in the figure are collectively referred to as 120).

[0091] In one possible implementation, Figure 1A The communication system shown can also be Figure 1B As shown, it includes a RAN node 110 and multiple terminals (such as Figure 1B In this case, a single RAN node may transmit data or control signaling to a single terminal or multiple terminals.

[0092] In another possible implementation, Figure 1A The communication system shown can also be Figure 1C As shown, it includes multiple RAN nodes (such as Figure 1C 110A, 110B and 110C in FIG. 110 and a terminal 120. In this case, multiple RAN nodes may also transmit data or control signaling for a single terminal at the same time.

[0093] At present, the terminal equipment under LP-WUS configuration adopts the MR and LR combination mode. MR is in deep sleep before being awakened by LP-WUS. The gain of LP-WUS comes from PDCCH monitoring instead of traditional PO, which saves power consumption. However, before monitoring PO, the terminal equipment still has to perform measurement, cell reselection judgment and other operations. If it is still based on traditional SSB measurement, the terminal also needs to turn on or partially turn on MR, which has a great impact on the gain of WUS.

[0094] In order to solve the above technical problems, the embodiments of the present application provide a communication method and related devices, wherein the network device configures the first indication information for the terminal device to indicate the WUS configuration of the neighboring area, so that the terminal device can perform neighboring area measurement through the neighboring area WUS. Furthermore, the neighboring area measurement can be performed through the first indication information in the LR state to implement operations such as cell reselection and switching measurement, thereby reducing the WUS gain impact caused by turning on the MR.

[0095] See also Figure 2 , 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 may be performed by a communication device (network device and / or terminal device), or may be performed by some components in the communication device (such as a processor, a chip or a chip system, etc.), or may be implemented by a logic module or software that can implement 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 may also be divided into executions by multiple execution subjects, and these execution subjects may 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 may be divided into executions by at least one of a CU, a DU and a RU. Steps 201 to 203 are described in detail below.

[0096] Step 201: The network device determines first indication information.

[0097] The network device determines the first indication information, which is used to indicate the time domain resource of the wake-up signal WUS of the neighboring area of ​​the terminal device, and the first indication information is used by the terminal device to perform neighboring area measurement. Alternatively, it can be understood that the WUS of the neighboring area is used by the terminal device to perform neighboring area measurement.

[0098] 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 according to the WUS of the neighboring cell.

[0099] The neighboring cell can also be understood as an adjacent cell, or as an adjacent cell of the cell where the terminal device is located. For example, Figure 3As shown, the neighboring cells of the cell where the terminal device is located include neighboring cell 1 and neighboring cell 2. It can be understood that Figure 2 This is just an example of neighboring cells. In actual applications, the number of neighboring cells of a terminal device can be even greater.

[0100] 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).

[0101] Optionally, the first indication information is also used to indicate at least one of the following: frequency domain resources of a neighboring WUS, code domain resources of a neighboring WUS (for example, a sequence or sequence range used by a neighboring 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.

[0102] Among them, the terminal device includes a first receiver and a second receiver, and the working power of the first receiver is less than the working 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. Or 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 switching measurement of the terminal device. The correction value can also be called an LR correction value, an offset or an offset coefficient, etc. Or it can be understood that the terminal device can obtain the measurement value of MR through the LR measurement value and the correction value without turning on MR, thereby reducing the power consumption of the terminal device turning on MR.

[0103] Optionally, in order to improve the correction effect, the configuration information may also 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, and specific neighboring areas of the terminal device. 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 neighboring area WUS measurement can be shared by all neighboring areas, shared by all same-frequency neighboring areas, or used separately by each cell.

[0104] Optionally, in order to schedule each terminal device in a more fine-grained manner, the network device may first determine the level (or LR level) of the first receiver of each terminal device, and determine the first indication information based on the level, and different levels correspond to different correction values. Alternatively, it can be understood that the correction values ​​of terminal devices of different LR levels are different.

[0105] 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.

[0106] 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.

[0107] It can be understood that the higher the LR level, the higher the correction value. The higher the LR level, the lower the correction value. The lower the LR level, the higher the correction value. The lower the LR level, the lower the correction value, etc. It can be set according to actual needs and is not limited here.

[0108] Exemplarily, the relationship between the LR level and the correction value of each terminal device may be shown in Table 1:

[0109] Table 1

[0110] LR Level Correction value 1 a 2 b 3 c 4 d

[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; when the LR level is 4, the correction value is d. It can be understood that Table 1 is only an example of the relationship between the LR level and the correction value, which 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, based on different states of the terminal device, the specific role of the first indication information may be different. For example, when the terminal device is in an idle state or an inactive state, the first indication information can be used by the terminal device to reselect a cell. For another example, when the terminal device is in a connected state, the first indication information can be used by the terminal device to perform switching measurements, etc. The specifics are not limited here.

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

[0115] For another example, in the measurement scenario of the first indication information in the connected state, the network device will unicast the measurement range and trigger conditions of the terminal. After the terminal triggers the measurement, it measures as required and then reports the result to the network device. The network device decides whether to switch the terminal to another cell and which cell to switch to based on the result reported by the terminal. Then, the network device sends a clear switching command to the terminal, including the identification and configuration of the target cell, etc. The terminal then accesses the target cell.

[0116] Optionally, the indication information is carried in a control channel. Specifically, the indication information may be at least one of the following: RRC signaling, MAC layer signaling, or physical layer signaling. The MAC layer signaling includes, for example, MAC CE; the physical layer signaling includes, 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 measurement, 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 results of a specific neighboring area. The terminal device can use the corrected WUS measurement results 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, so as not to use a high-power receiver (ie, MR) for measurement to reduce power consumption. That is, the terminal device uses the LR to perform a neighboring WUS measurement to obtain a WUS measurement result (ie, a first measurement value), and adjusts the WUS measurement result by a correction value (eg, adding a correction value, multiplying by a correction value, or dividing by a correction value, etc.) to estimate the WUS measurement result of the MR (ie, a second measurement value).

[0124] Exemplarily, 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 using the correction value b indicated by the configuration information and a.

[0125] Similarly, based on the different states of the terminal device, the specific role of the first indication information may be different. For example, when the terminal device is in an idle state or an inactive state, the terminal device can reselect a cell based on the first indication information. For another example, when the terminal device is in a connected state, the terminal device can perform switching measurements based on the first indication information. This is not specifically limited here.

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