[0007] By using the cell measurement method provided by the embodiments of the present application, the terminal device measures and reports the measurement result of the at least one candidate cell based on the first indication information of the network device, and measures the first candidate cell a first number of times within a first time period based on the second indication information of the network device, which can flexibly control the number of measurement objects and the number of measurements of the terminal device, and is beneficial to reduce the energy consumption of the terminal device.

[0008] It should be noted that the serving cell is a cell currently serving the terminal device, i.e., a source cell.

[0009] In a possible implementation, the first indication information can be a radio resource control (RRC) message or can be carried in an RRC message.

[0010] Optionally, the first indication information can be a medium access control control element (MAC CE) or downlink control information (DCI).

[0011] In a possible implementation, the first indication information can include at least one measurement identifier, the at least one measurement identifier corresponding to the at least one candidate cell in a one-to-one manner, and each measurement identifier being used to indicate whether measurement on the candidate cell corresponding to the measurement identifier is needed.

[0012] Optionally, before the terminal device sends the report message 2 to the network device, the terminal device performs measurement on the at least one candidate cell based on the first indication information to obtain measurement results of the at least one candidate cell.

[0013] In a possible implementation, the cell measurement in the embodiments of the present application can include measurement of quality of a cell.

[0014] Optionally, before the terminal device sends the first report message 2 to the network device, the method can further include: the terminal device performs measurement on the at least one candidate cell based on the first indication information to obtain measurement results of the at least one candidate cell.

[0023] Optionally, the second number can be greater than or equal to 0.

[0024] In a possible implementation, when the number of the at least one candidate cell is greater than 1, if the second number is equal to 0, it can be understood that, within the first time period, the terminal device only needs to perform the first number of measurements on the candidate cell with good quality in the at least one candidate cell, and does not need to perform measurements on the candidate cell with poor quality in the at least one candidate cell. In this way, the number of measurement objects can be reduced, thereby reducing the energy consumption of the terminal device.

[0030] That is, the terminal device can determine by itself whether to start the measurement GAP. In this way, the interaction between the network device and the terminal device can be reduced, and thus the energy consumption of the terminal device can be reduced.

[0031] In a possible implementation, the second indication information further indicates to start the measurement GAP, and before the measurement of the first candidate cell for the first number of times within the first time period based on the second indication information, the method further includes: starting the measurement GAP based on the second indication information.

[0032] That is, the terminal device can start the measurement GAP based on the indication of the network. In this way, the calculation amount of the terminal device can be reduced, and thus the energy consumption of the terminal device can be reduced.

[0033] In a second aspect, an embodiment of the present application provides a cell measurement method, which can include: sending first indication information to a terminal device, the first indication information being used to indicate that at least one candidate cell needs to be measured; receiving a first report message from the terminal device, the first report message being used to indicate a measurement result of the at least one candidate cell; and sending second indication information to the terminal device based on the first report message, the second indication information being used to indicate that a first candidate cell is measured for a first number of times within a first time period, the at least one candidate cell including the first candidate cell, and a quality of the first candidate cell in the measurement result of the at least one candidate cell being greater than or equal to a first threshold value.

[0034] By using the cell measurement method provided in the embodiment of the present application, the network device indicates the terminal device to measure and report the measurement result of the at least one candidate cell through the first indication information, and sends the second indication information to the terminal device based on the first report message sent by the terminal device, to indicate the terminal device to measure the first candidate cell for the first number of times within the first time period, so that the number of measurement objects and the number of measurements of the terminal device can be flexibly controlled, and the energy consumption of the terminal device can be reduced.

[0035] In a possible implementation, the second indication information includes first number information and time information, the first number information being used to indicate the first number, and the time information being used to indicate the first time period.

[0036] In a possible implementation, the at least one candidate cell further includes a second candidate cell, and the second indication information is further used to indicate that the second candidate cell is measured a second number of times within the first time period, the first number of times is greater than the second number of times, and a quality of the second candidate cell in the measurement result of the at least one candidate cell is less than the first threshold value.

[0037] In a possible implementation, the second indication information further includes second number information, and the second number information is used to indicate the second number of times.

[0038] In a possible implementation, the second indication information is a media access control (MAC) control element (CE) or downlink control information (DCI).

[0040] It should be noted that parts not described in detail in the second aspect can refer to the descriptions of the corresponding parts in the first aspect, and details are not described here to avoid repetition.

[0041] In a third aspect, an embodiment of the present application provides a cell measurement method, which can include: performing measurement on at least one candidate cell; and based on a measurement result of the at least one candidate cell, performing measurement on a first candidate cell a first number of times within a first time period, the at least one candidate cell including the first candidate cell, and a quality of the first candidate cell in the measurement result of the at least one candidate cell being greater than or equal to a first threshold value.

[0042] By using the cell measurement method provided in the embodiment of the present application, the terminal device can perform measurement on a first candidate cell a first number of times within a first time period based on a measurement result of at least one candidate cell, which can flexibly control the number of measurement objects and the number of measurements of the terminal device, and is beneficial to reducing the energy consumption of the terminal device.

[0043] In a possible implementation, the terminal device can perform measurement on the at least one candidate cell once.

[0044] For example, the measurement result can include at least one of a reference signal received power (RSRP), a reference signal received quality (RSRQ), or a signal to interference plus noise ratio (SINR).

[0045] In a possible implementation, before the measurement on the first candidate cell a first number of times within the first time period based on the measurement result of the at least one candidate cell, the method further includes: sending a second reporting message to a network device, the second reporting message being used to indicate that measurement on the first candidate cell is needed.

[0046] Optionally, before the first terminal device performs the first number of measurements on the first candidate cell within the first time period based on the measurement results of the at least one candidate cell, the first terminal device can further report to the network device that the third candidate cell also needs to be measured.

[0048] Optionally, the first terminal device can report that the first candidate cell and the third candidate cell need to be measured in various ways.

[0049] In a possible implementation, the first terminal device can report that the first candidate cell and the third candidate cell need to be measured through one report message after measuring the at least one candidate cell.

[0050] For example, the second report message is further used to indicate that the third candidate cell needs to be measured.

[0051] In another possible implementation, the first terminal device can report that the first candidate cell needs to be measured through one report message after measuring that the quality of the first candidate cell is greater than or equal to the first threshold value, and report that the third candidate cell needs to be measured through another report message after measuring that the quality of the third candidate cell is greater than or equal to the first threshold value.

[0053] In a possible implementation, the at least one candidate cell further includes a second candidate cell, and the method further includes: based on the measurement results of the at least one candidate cell, performing a second number of measurements on the second candidate cell within the first time period, the quality of the second candidate cell in the measurement results of the at least one candidate cell is less than the first threshold value, and the first number is greater than the second number.

[0054] Optionally, the second number can be greater than or equal to 0.

[0055] In a possible implementation, when the number of the at least one candidate cell is greater than 1, if the second number of times is equal to 0, it can be understood that, in the first time period, the terminal device only needs to perform measurement on the candidate cell with good quality in the at least one candidate cell, and does not need to perform measurement on the candidate cell with poor quality in the at least one candidate cell. In this way, the number of measurement objects can be reduced, and thus the energy consumption of the terminal device is reduced.

In this way, the total number of cell measurements can be reduced, and thus the energy consumption of the terminal device is reduced.

[0058] Optionally, in the embodiment of the application, in the first time period, the terminal device performs the measurement with the high number of times on the candidate cell with good quality in the at least one candidate cell can be replaced by that the terminal device performs the measurement with a small period (i.e., high frequency measurement) on the candidate cell with good quality in the at least one candidate cell; or the terminal device performs the measurement with the low number of times on the candidate cell with poor quality in the at least one candidate cell can be replaced by that the terminal device performs the measurement with a large period (i.e., low frequency measurement) on the candidate cell with poor quality in the at least one candidate cell.

[0059] In a possible implementation, the first time period and / or the first threshold value are preconfigured. In this way, the interaction between the network device and the terminal device can be reduced, and thus the energy consumption of the terminal device is reduced.

[0061] That is, the terminal device can determine whether to start the measurement GAP by itself. In this way, the interaction between the network device and the terminal device can be reduced, and thus the energy consumption of the terminal device is reduced.

[0123] The technical solutions in the present application will be described below with reference to the drawings.

[0124] In the embodiments of the present application, the same items or similar items with basically the same functions and effects are distinguished by using "first", "second", etc. For example, the first chip and the second chip are merely used to distinguish different chips, and do not limit the sequence. Those skilled in the art can understand that "first", "second", etc. do not limit the quantity and execution sequence, and "first", "second", etc. also do not necessarily mean different.

[0125] It should be noted that in the embodiments of the present application, the words "exemplarily" or "for example" are used to represent an example, illustration or explanation. Any embodiment or design scheme described as "exemplarily" or "for example" in the present application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. Rather, the words "exemplarily" or "for example" are used to present the relevant concept in a specific manner.

[0126] In the embodiments of the present application, "at least one" means one or more, and "multiple" means two or more. The "and / or" describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the front and rear associated objects. "At least one of the following" or similar expressions means any combination of these items, including any combination of single or multiple items. For example, at least one of a, b, or c can represent a, b, c, a-b, a-c, b-c, or a-b-c, where a, b, and c can be single or multiple.

[0127] In order to clearly describe the technical solutions of the embodiments of the present application, first, some terms and technologies related to the embodiments of the present application are briefly introduced:

[0128] 1. Cell: A cell is described from the perspective of resource management or mobility management or service unit by a higher layer. The coverage of each network device can be divided into one or more cells, and each cell can correspond to one or more frequency points, or in other words, each cell can be regarded as an area formed by the coverage of one or more frequency points.

[0129] It should be noted that a cell can be an area where the coverage of the wireless network of a network device is located. In the embodiments of the present application, different cells can correspond to the same or different network devices. For example, the network device to which cell #1 belongs and the network device of cell #2 can be different network devices, such as base stations. That is, cell #1 and cell #2 can be managed by different base stations. Or, for example, the network device managing cell #1 and the network device managing cell #2 can also be different radio frequency processing units of the same base station, such as radio remote units (RRUs). That is, cell #1 and cell #2 can be managed by the same base station, have the same baseband processing unit and intermediate frequency processing unit, but have different video processing units. Or, for example, the network device to which cell #1 belongs and the network device to which cell #2 belongs can be the same network device, such as a base station. That is, cell #1 and cell #2 can be managed by the same base station, which can be referred to as cell #1 and cell #2 co-sited, and the embodiments of the present application do not particularly limit this.

[0130] By way of example, a base station can include a central unit (CU) and / or one or more distributed units (DUs) in some possible deployments. Under such a deployment, cell 1# and cell 2# can be managed by the same CU and the same DU, i.e., co-CU and co-DU; or, cell 1# and cell 2# can be managed by the same CU and different DUs, i.e., co-CU but not co-DU; or, cell 1# and cell 2# can also be managed by different CUs and different DUs, i.e., not co-CU and not co-DU.

[0131] 2. Reference signal

[0132] In a wireless communication system, a reference signal (RS) is a special signal used for channel measurement and calibration, usually transmitted in a predetermined manner and time interval in the communication link. The reference signal helps the receiving end to perform channel estimation, synchronization, power control and other key functions, so as to ensure the accuracy and stability of data transmission.

[0133] The reference signal is used to measure channel state information (CSI), so as to help the receiving end to estimate the channel characteristics, such as path loss, multipath effect, etc. It can also be used for time synchronization and frequency synchronization to ensure that the transmitting end and the receiving end communicate at the same time and frequency; measure the strength of the received signal, so as to perform power control to ensure that the signal is transmitted at the appropriate power level. The reference signal can also be used for cell selection and handover, and the user equipment (UE) uses the quality of the reference signal to select the best cell to connect to and perform inter-cell handover during movement. In a multi-cell environment, the reference signal helps to coordinate and reduce inter-cell interference, improving the overall performance of the network.

[0134] For example, taking the 5G NR system as an example, common reference signals include: a demodulation reference signal (DM-RS), used for data demodulation of downlink and uplink, transmitted during data transmission; a phase tracking reference signal (PT-RS), used for phase noise correction, especially at high frequencies; a synchronization signal and physical broadcast channel block (SS / PBCH Block), including a synchronization signal (SS) and a physical broadcast channel (PBCH), used for initial synchronization and broadcast system information; a channel state information reference signal (CSI RS), used for channel state information measurement of downlink, helping to perform beamforming and multiple-input multiple-output (MIMO) operation; a sounding reference signal (SRS), used for uplink channel measurement.

[0135] 3. Handover

[0136] In a wireless communication system, when a terminal device moves / closes to another cell from a cell, in order to maintain the communication of the terminal device, handover needs to be performed. In the embodiments of the present application, the source cell represents the cell that provides services for the terminal device before handover, and the target cell represents the cell that provides services for the terminal device after handover. The related information of the target cell (such as the physical cell identifier of the target cell, frequency information, random access resource information required for handover to the target cell, etc.) can be indicated by a handover message sent by the network device to which the source cell belongs (i.e. the source network device) to the terminal device.

[0137] The handover can be an intra-station handover or an inter-station handover. The intra-station handover can refer to that the source cell and the target cell belong to the same network device (such as a base station), wherein the source cell and the target cell can be the same cell or different cells. The inter-station handover refers to that the source cell and the target cell belong to different network devices (such as base stations). The present application does not limit this.

[0138] For example, the source cell corresponds to a source network device (for example, a source base station), and the target cell corresponds to a target network device (for example, a target base station), wherein the source base station and the target base station can be the same or different.

[0139] 4. L1 / L2 layer triggered mobility (L1 / L2LTM) handover

[0140] L1 / L2LTM handover, also called L1 / L2 handover. Wherein L1 refers to the physical layer, L2 refers to the medium access control (MAC) layer / radio link control (RLC) layer / packet data convergence protocol (PDCP) / service data adaptation protocol (SDAP) layer.

[0141] For example, in the L1 / L2 handover process, L2 mainly refers to the MAC layer.

[0142] For example, under the architecture of CU-DU separation of the base station, the L1 / L2LTM process is as follows: the terminal device sends the L1 measurement result to the base station through physical layer control signaling (carried on the physical uplink control channel (PUCCH)), the physical layer of the base station reads the L1 measurement result, and according to the measurement result, the handover decision made by the base station is sent to the terminal device through L1 / L2 signaling, which can be a message carried on the physical downlink control channel (PDCCH) or a MAC control element (MAC CE).

[0143] 5. LTM event

[0144] LTM2 event (Event LTM2): the quality of the serving cell and / or reference signal is less than threshold 1;

[0145] LTM3 event (Event LTM3): the quality of the candidate cell and / or reference signal is greater than or equal to the quality of the serving cell;

[0146] LTM4 event (Event LTM4): the quality of the candidate cell and / or reference signal is greater than or equal to threshold 2;

[0147] LTM5 event (Event LTM5): the quality of the serving cell and / or reference signal is less than or equal to threshold 3, and the quality of the candidate cell and / or reference signal is greater than or equal to threshold 4.

[0148] 6. Measurement GAP

[0149] The measurement GAP is used when the terminal device receiver bandwidth is insufficient to cover the service cell frequency point and the frequency point where the to-be-measured cell is located at the same time. The terminal device will measure the to-be-measured cell with a certain GAP. In the case of single radio frequency, for inter-frequency and inter-system, the terminal device needs the assistance of the measurement GAP to effectively measure.

[0150] The technical solutions of the embodiments of the present application can be applied to various communication systems. For example, global system for mobile communications (GSM), long term evolution (LTE) system, universal mobile telecommunications system (UMTS), 4th generation (4G) mobile communication system, 4.5th generation (4.5G) mobile communication system, Worldwide Interoperability for Microwave Access (WiMAX) communication system, 5th generation (5G) mobile communication system or new radio Access Technology (NR), and as the communication technology continues to develop, the technical solutions of the embodiments of the present application can also be applied to subsequent evolved communication systems, such as 6th generation (6G) mobile communication system, 7th generation (7G) mobile communication system, etc. The technical solutions of the embodiments of the present application can also be applied to universal mobile telecommunications system (UMTS), code division multiple access (CDMA) system, wireless local area network (WLAN), etc. The technical solutions of the embodiments of the present application can also be applied to vehicle-to-X (V2X), wherein V2X can include vehicle to network (V2N), vehicle to vehicle (V2V), vehicle to infrastructure (V2I), vehicle to pedestrian (V2P), Long Term Evolution-Vehicle (LTE-V), Internet of Vehicles, machine type communication (MTC), Internet of Things (IoT), Long Term Evolution-Machine (LTE-M), Machine to Machine (M2M), etc.

For example, the terminal device is simultaneously located in the coverage of a cell managed by a network device #1, a cell managed by a network device #2 and a cell managed by a network device #3. The network device #1 can be a macro evolutional Node B (macro eNB or macro e-NodeB) for example, and the network device #2 and the network device #3 can be small eNBs (small e-NodeBs) for example.

Therefore, the network device and the terminal device can communicate with each other through antenna technology.

[0157] Optionally, the communication system 100 can further include other network entities such as a network controller, a mobility management entity, or a core network network element, and the embodiments of the present application are not limited thereto.

The embodiments of the present application do not limit the foregoing.

[0159] In the embodiments of the present application, the network device can be an access network device, which is a radio access network (RAN) node (or device) for accessing a terminal device to a wireless network. The network device includes but is not limited to: a base station (BS), a radio network controller (RNC), a base station controller (BSC), a network device transceiver station (BTS), a home base station (for example, a home evolved Node B, or a home Node B, HNB), a baseband unit (BBU), a wireless fidelity (Wifi) access point (AP), a wireless relay node, a wireless backhaul node, a transmission and reception point (TRP; or, a transmission point, TP). Among them, the base station is a device deployed in a wireless access network that can provide wireless communication functions, which can also be referred to as a base station device, for example, an evolved Node B (eNB or e-NodeB) in the LTE system, a Node B (NB), a base station (gNodeB or gNB) in the 5G system, a base station in the 6G system, etc. The base station can include a BBU and a remote radio unit (RRU). The BBU and the RRU can be placed in different places, for example: RRU pullout, placed in a high traffic area, BBU placed in a central machine room. The BBU and the RRU can also be placed in the same machine room. The BBU and the RRU can also be different components under one rack. The base station can be in the following forms: macro base station, micro base station (also known as small station), pico base station, relay station, access point, balloon station, etc.

[0160] Optionally, in some deployments of the network device, the network device can adopt a central unit (CU)-distributed unit (DU) separation architecture, that is, the network device can include a CU and / or a DU. The protocol layers in the communication protocol stack of the network device are respectively deployed in the CU and / or the DU, that is, the functions of part of the protocol layers are controlled by the CU, and the functions of the remaining part or all of the protocol layers are controlled by the CU.

[0161] Optionally, the CU and the DU can be physically arranged together or physically separated, and the embodiments of the present application do not limit this.

[0162] Optionally, in some deployments of the network device, the CU can also be divided into a CU-control plane (CP) and a CU-user plane (UP), etc.

[0163] Optionally, in some other deployments of the network device, the network device can also be an open radio access network (ORAN) architecture, etc. The specific deployment of the network device is not limited in the present application.

[0164] For example, FIG. 2 shows a CU-DU separation architecture of the network device provided by the embodiments of the present application. As shown in FIG. 2, the network device can include a CU and at least one DU, and each DU can be connected with the CU through an F1 interface. The information interaction between different DUs can be completed through the forwarding of the CU.

[0165] For example, the DU can support the functions of radio link control (RLC), media access control (MAC) and physical layer (PHY), and the CU can support the functions of the radio resource control layer (RRC), the packet data convergence layer protocol (PDCP) and the service data adaptation protocol (SDAP) layer.

[0166] It should be noted that the above enumeration of the protocol layers deployed in the CU and the DU is only exemplary and should not constitute any limitation on the present application. The protocol layers deployed in the CU and / or the DU can also be existing protocols (for example, other protocol layers defined in the long term evolution (LTE) protocol or future protocols, which are not limited in the embodiments of the present application.

[0167] It should also be noted that the functions of each protocol layer mentioned in the embodiments of the present application can change, which is not limited in the embodiments of the present application.

[0168] It should be noted that only cell measurement is taken as an example to describe the technical solutions of the present application in the embodiments of the present application, but the embodiments of the present application are not limited to be used for measuring cells, and the ideas and method processes of the cell measurement method and device provided by the embodiments of the present application can be similarly used for the measurement method and device of the reference signal.

[0169] Optionally, the cell measurement method and device provided in the embodiments of the present application are applicable to various application scenarios requiring cell measurement.

[0170] For example, the cell measurement in the embodiments of the present application can include measuring the quality of a cell.

[0171] For example, FIG. 3 shows an application scenario diagram provided in the embodiments of the present application. As shown in FIG. 3, cell 1 is a serving cell currently providing services for a terminal device, i.e., a source cell, and cells 2 to 6 are candidate cells available or detectable to the terminal device. The terminal device can measure the quality of the candidate cells by using the cell measurement method provided in the embodiments of the present application, and report the measurement results to a network device. The network device can determine whether the terminal device needs to be switched from the current serving cell (i.e., the source cell) to a candidate cell (i.e., a target cell) based on the measurement results.

[0172] In the prior art, the network device sends a measurement configuration to the terminal device, and the terminal device measures the cells that can be detected based on the measurement configuration. The measurement objects and the number of measurements are large, and therefore, the energy consumption of the terminal device is large.

[0173] The embodiments of the present application provide a cell measurement method and device. The network device sends first indication information to the terminal device, where the first indication information is used to indicate measurement on at least one candidate cell. The terminal device sends a first reporting message to the network device, where the first reporting message is used to indicate the measurement results of the at least one candidate cell. The network device sends second indication information to the terminal device based on the first reporting message, where the second indication information is used to indicate measurement on a first candidate cell for a first number of times within a first time period, the at least one candidate cell includes the first candidate cell, and the quality of the first candidate cell in the measurement results of the at least one candidate cell is greater than or equal to a first threshold value. The terminal device measures the first candidate cell based on the second indication information.

[0174] That is, the terminal device measures and reports the measurement results of at least one candidate cell based on the first indication information of the network device, and measures the first candidate cell for a first number of times within a first time period based on the second indication information of the network device. The number of measurement objects and the number of measurements of the terminal device can be flexibly controlled, which is beneficial to reducing the energy consumption of the terminal device.

[0175] The embodiment of the present application further provides another method and device for cell measurement. A terminal device measures at least one candidate cell; and based on the measurement results of the at least one candidate cell, the terminal device measures a first candidate cell a first number of times within a first time period, the at least one candidate cell including the first candidate cell, and the quality of the first candidate cell in the measurement results of the at least one candidate cell being greater than or equal to a first threshold value.

[0176] That is, the terminal device can measure a first candidate cell a first number of times within a first time period based on the measurement results of the at least one candidate cell, which can flexibly control the number of measurement objects and the number of measurements of the terminal device, and is beneficial to reduce the energy consumption of the terminal device.

[0177] It should be understood that the following is only for the convenience of understanding and illustration, and the method provided by the embodiment of the present application is described in detail taking the interaction between the terminal device and the network device as an example. However, this should not constitute any limitation on the execution subject of the method provided by the present application. For example, the terminal device shown in the following embodiment can be replaced by a component (such as a chip or a circuit) configured in the terminal device. The network device shown in the following embodiment can also be replaced by a component (such as a chip or a circuit) configured in the network device.

[0178] The following embodiments shown do not particularly limit the specific structure of the execution subject of the method provided by the embodiment of the present application, as long as the execution subject can communicate according to the method provided by the embodiment of the present application by running the program in which the code of the method provided by the embodiment of the present application is recorded. For example, the execution subject of the method provided by the embodiment of the present application can be a terminal device or a network device, or a functional module in the terminal device or the network device that can call and execute the program.

[0179] FIG. 4 is a schematic flowchart of the cell measurement method 200 provided by the embodiment of the present application from the perspective of device interaction. As shown in FIG. 4, the method 200 can include S201 to S209. The following describes each step of the method 200 in detail.

[0180] S201. The terminal device measures a serving cell.

[0181] It should be noted that the serving cell is a cell currently providing services for the terminal device, i.e., a source cell.

[0182] In one possible implementation, the cell measurement in the embodiment of the present application can include measuring the quality of the cell.

[0183] Optionally, the measurement result of the cell measurement (i.e., the measurement result of the cell quality measurement) can include one or more of the following parameters: reference signal received power (RSRP), reference signal received quality (RSRQ), or signal to interference plus noise ratio (SINR).

[0184] S202. If the quality of the serving cell is lower than the threshold value 1, the terminal device sends a reporting message 1 to the network device, where the reporting message 1 is used to report that the quality of the serving cell is lower than the threshold value 1. Correspondingly, the network device receives the reporting message 1 from the terminal device.

[0185] That is, if the terminal device determines that the triggering condition of the LTM2 event is met, the terminal device reports the LTM2 event to the network device.

[0186] Optionally, the terminal device can obtain the threshold value 1 in multiple ways.

[0187] In a possible implementation, the threshold value 1 can be pre-configured.

[0188] For example, the threshold value 1 can be pre-configured by the network device through an RRC message.

[0189] In another possible implementation, the terminal device can receive the threshold value 1 sent by other devices (such as other terminal devices).

[0190] For example, the terminal device A can receive the threshold value 1 sent by the terminal device B.

[0191] S203. The network device sends first indication information to the terminal device based on the reporting message 1, where the first indication information is used to indicate that at least one candidate cell needs to be measured. Correspondingly, the terminal device receives the first indication information from the network device.

[0192] In a possible implementation, the first indication information can be a radio resource control (RRC) message, or can be carried in an RRC message.

[0193] Optionally, the first indication information can be a medium access control (MAC) control element (CE) or downlink control information (DCI).

[0194] In a possible implementation, the first indication information can include at least one measurement identifier, the at least one measurement identifier corresponding to the at least one candidate cell in a one-to-one manner, and each measurement identifier being used to indicate whether measurement on the candidate cell corresponding to the measurement identifier is needed.

[0195] For example, the first indication information can include at least one bit, the at least one bit corresponding to the at least one candidate cell in a one-to-one manner, and the value of each bit in the at least one bit being used to represent the measurement identifier of the candidate cell corresponding to the bit.

[0196] For example, taking the first indication information as a MAC CE1, FIG. 5 shows a format diagram of the MAC CE1 according to an embodiment of the present application. As shown in FIG. 5, the MAC CE1 includes 8 bits C1-C8, wherein C1 corresponds to candidate cell 1 (i.e., the first candidate cell), C2 corresponds to candidate cell 2, …, and C8 corresponds to candidate cell 8. The value of C1 (i.e., the measurement identifier of candidate cell 1) is "1", indicating that measurement on candidate cell 1 is needed, the value of C2 is "1", indicating that measurement on candidate cell 2 is needed, …, and the value of C8 is "1", indicating that measurement on candidate cell 8 is needed.

[0197] It should be noted that FIG. 5 only schematically shows that the MAC CE1 includes 8 bits, and the values of the 8 bits are all "1", but the embodiments of the present application are not limited thereto. Optionally, the MAC CE1 can also include other numbers of bits, and the value of each bit can be "0" or "1", wherein the value of a bit being "0" indicates that measurement on the candidate cell corresponding to the bit is not needed, and the embodiments of the present application are not limited thereto.

[0198] S204. The terminal device sends a reporting message 2 (i.e., a first reporting message) to the network device, the reporting message 2 being used to indicate the measurement result of the at least one candidate cell. Correspondingly, the network device receives the reporting message 2 from the terminal device.

[0199] Optionally, before sending the reporting message 2 to the network device, the method 200 can further include: based on the first indication information, the terminal device performs measurement on the at least one candidate cell once to obtain the measurement result of the at least one candidate cell.

[0200] Optionally, the measurement result can include at least one of RSRP, RSRQ or SINR.

[0201] S205. The network device sends, based on the reporting message 2, second indication information to the terminal device, the second indication information being used to indicate that the first candidate cell is measured for the first number of times within the first time period, the at least one candidate cell including the first candidate cell, and the quality of the first candidate cell in the measurement result of the at least one candidate cell being greater than or equal to a threshold value 2 (i.e. a first threshold value). Correspondingly, the terminal device receives the reporting message 2 from the network device.

[0202] Optionally, the network device can acquire the threshold value 2 in multiple ways.

[0203] In a possible implementation, the threshold value 2 can be pre-set.

[0204] In another possible implementation, the network device can receive the threshold value 2 sent by other devices (such as other network devices).

[0205] For example, the network device A can receive the threshold value 2 sent by the network device B.

[0206] In a possible implementation, the second indication information can be MAC CE or DCI.

[0207] In a possible implementation, the second indication information can include first number information and time information, the first number information being used to indicate the first number of times, and the time information being used to indicate the first time period.

[0208] In a possible implementation, the second indication information can further include at least one measurement identifier.

[0209] For example, the second indication information can include at least one bit of measurement identifier, N bits of time information and M bits of first number information corresponding to the first candidate cell, M and N both being greater than 0.

[0210] For example, taking the second indication information as the MAC CE2 for example, FIG. 6 shows a format diagram of the MAC CE2 provided by the embodiment of the present application. As shown in FIG. 6, the MAC CE2 includes 8 bits of measurement identifiers, which are C1-C8 respectively, wherein C1 corresponds to the candidate cell 1 (i.e. the first candidate cell), C2 corresponds to the candidate cell 2, …, and C8 corresponds to the candidate cell 8. The value of C1 (i.e. the measurement identifier of the candidate cell 1) is "1", which indicates that the measurement of the candidate cell 1 is needed, the value of C2 is "1", which indicates that the measurement of the candidate cell 2 is needed, …, and the value of C8 is "1", which indicates that the measurement of the candidate cell 8 is needed. The MAC CE2 further includes 4 bits of first number information corresponding to C1. The 4 bits of the first number information have the value of "1111", which indicates that the first number (e.g. N C1 in FIG. 6) is 15. The MAC CE2 further includes 8 bits of time information. The 8 bits of the time information have the value of "01100100", which indicates that the first time period is 100 ms.

[0211] It should be further noted that FIG. 6 only takes the first number information corresponding to C1 (i.e. the candidate cell 1) in the MAC CE2 (used to indicate N C1 ) as an example for introduction, but the embodiment of the present application does not make any limitation in this regard. Alternatively, the MAC CE2 can further include the number information (used to indicate at least one of N C2 -N C8 ) corresponding to at least one bit of C2-C8 (i.e. at least one of the candidate cell 2 to the candidate cell 8), and the embodiment of the present application does not make any limitation in this regard.

[0212] Alternatively, the at least one candidate cell can further include a second candidate cell, and the second indication information is further used to indicate that the measurement of the second number is performed on the second candidate cell within the first time period, the first number is greater than the second number, and the quality of the second candidate cell in the measurement result of the at least one candidate cell is less than the first threshold value.

[0213] Alternatively, the second indication information further includes the second number information, and the second number information is used to indicate the second number.

[0214] For example, the second indication information can include at least one bit of measurement identifier, N bits of time information, M bits of first number information corresponding to the first candidate cell, and M bits of second number information corresponding to the second candidate cell, wherein M and N are both greater than 0.

[0215] For example, taking the second indication information as the MAC CE2 for example, FIG. 7 shows another format of the MAC CE2 provided by the embodiment of the present application. As shown in FIG. 7, the MAC CE2 includes 8 bits of measurement identifiers, which are C1-C8 respectively, wherein C1 corresponds to the candidate cell 1 (i.e. the first candidate cell), C2 corresponds to the candidate cell 2, and C8 corresponds to the candidate cell 8. The value of C1 (i.e. the measurement identifier of the candidate cell 1) is "1", which indicates that the measurement of the candidate cell 1 is needed, the value of C2 is "1", which indicates that the measurement of the candidate cell 2 is needed, and the value of C8 is "1", which indicates that the measurement of the candidate cell 8 is needed. The MAC CE2 further includes 4 bits of first frequency information corresponding to C1, and the 4 bits of the first frequency information have the value of "1111", which indicates that the first frequency (i.e. N C1 in FIG. 7) is 15. The MAC CE2 further includes 4 bits of second frequency information corresponding to C2, and the 4 bits of the second frequency information have the value of "0010", which indicates that the second frequency (i.e. N C2 in FIG. 7) is 2. The MAC CE2 further includes 8 bits of time information, and the 8 bits of the time information have the value of "01100100", which indicates that the first time period is 100 ms.

[0216] It should be noted that FIG. 6 and FIG. 7 only schematically show that the MAC CE2 includes 8 bits of measurement identifiers, and the values of the 8 bits are all "1", but the embodiment of the present application is not limited thereto. Alternatively, the MAC CE2 can further include other number of measurement identifiers, and the value of each bit can be "0" or "1". Wherein the value of the bit is "0", which indicates that the measurement of the candidate cell corresponding to the bit is not needed, and accordingly, the frequency information corresponding to the measurement identifier with the value of "0" in the MAC CE2 can be 0, or the 4 bits of frequency information corresponding to the measurement identifier with the value of "0" can not be carried, and the embodiment of the present application does not limit this.

[0217] It should be further noted that FIG. 6 and FIG. 7 only schematically show that the MAC CE2 includes 8 bits of time information and 4 bits of frequency information (such as the first frequency information or the second frequency information), but the embodiment of the present application is not limited thereto. Alternatively, the MAC CE2 can further include other number of time information and / or frequency information, and the embodiment of the present application does not limit this.

[0218] It should be further noted that FIG. 7 only takes the MAC CE2 to include the first frequency information corresponding to C1 (i.e. the candidate cell 1) (used to indicate the first frequency N C1 ) and the second frequency information corresponding to C2 (i.e. the candidate cell 2) (used to indicate the second frequency N C2) is introduced as an example, but embodiments of the present application do not limit this. Optionally, the MAC CE2 can further include: the number information (used for indicating N C3 ~N C8 at least one of C3~C8), and embodiments of the present application do not limit this.

[0219] S206. The terminal device performs the measurement of the first number of times on the first candidate cell within the first time period based on the indication information 2.

[0220] Optionally, the method 200 can further include: the terminal device performs the measurement of the second number of times on the second candidate cell within the first time period based on the indication information 2.

[0221] Optionally, the second number of times can be greater than or equal to 0.

[0222] In a possible implementation, when the number of the at least one candidate cell is greater than 1, if the second number of times is equal to 0, it can be understood that: within the first time period, the terminal device only needs to perform the measurement of the first number of times on the candidate cell with good quality in the at least one candidate cell, and does not need to perform the measurement on the candidate cell with poor quality in the at least one candidate cell. In this way, the number of measurement objects can be reduced, thereby reducing the energy consumption of the terminal device.

[0223] Optionally, in embodiments of the present application, within the first time period, the terminal device performs the measurement of a high number of times on the candidate cell with good quality in the at least one candidate cell, which can be replaced by that the terminal device performs the measurement of a first period on the candidate cell with good quality in the at least one candidate cell.

[0224] In another possible implementation, when the number of the at least one candidate cell is greater than 1, if the second number of times is greater than 0, and the first number of times is greater than the second number of times, it can be understood that: within the first time period, the terminal device performs the measurement of a high number of times on the candidate cell with good quality in the at least one candidate cell, and performs the measurement of a low number of times on the candidate cell with poor quality in the at least one candidate cell. In this way, the total number of cell measurements can be reduced, thereby reducing the energy consumption of the terminal device.

[0225] Optionally, in the embodiments of the present application, in the first time period, the terminal device performs the measurement of the candidate cell with good quality in the at least one candidate cell for a high number of times, which can be replaced by that the terminal device performs the measurement of the candidate cell with good quality in the at least one candidate cell for a small period (i.e. high frequency measurement); or the terminal device performs the measurement of the candidate cell with poor quality in the at least one candidate cell for a low number of times, which can be replaced by that the terminal device performs the measurement of the candidate cell with poor quality in the at least one candidate cell for a large period (i.e. low frequency measurement).

[0226] Optionally, before S206, the terminal device can determine that the measurement GAP needs to be started in various manners.

[0227] In a possible implementation, the terminal device determines that the first candidate cell and the serving cell belong to inter-frequency cells or inter-system cells, and starts the measurement GAP. That is, the terminal device can determine by itself whether the measurement GAP needs to be started.

[0228] In another possible implementation, the second indication information further indicates to start the measurement GAP, and the terminal device starts the measurement GAP based on the second indication information. That is, the network device determines that the first candidate cell and the serving cell belong to inter-frequency cells or inter-system cells, and the terminal device can start the measurement GAP based on the indication of the network device.

[0229] Optionally, the second indication information can further include Q-bit GAP indication information, where Q is greater than 0, and the GAP indication information is used to indicate whether the measurement GAP needs to be started.

[0230] For example, taking the second indication information as the MAC CE2, FIG. 8 shows another schematic diagram of the MAC CE2 provided by the embodiments of the present application. As shown in FIG. 8, the MAC CE2 includes 8 bits of measurement identifiers, which are C1-C8, where C1 corresponds to the candidate cell 1 (i.e. the first candidate cell), C2 corresponds to the candidate cell 2,..., and C8 corresponds to the candidate cell 8. The value of C1 (i.e. the measurement identifier of the candidate cell 1) is "1", which indicates that the measurement of the candidate cell 1 needs to be performed, the value of C2 is "1", which indicates that the measurement of the candidate cell 2 needs to be performed,..., and the value of C8 is "1", which indicates that the measurement of the candidate cell 8 needs to be performed. The MAC CE2 further includes 4 bits of first number information corresponding to C1, and the 4 bits of the first number information have the value of "1111", which indicates that the first number (N C1 in FIG. 8) is 15. The MAC CE2 further includes 4 bits of second number information corresponding to C2, and the 4 bits of the second number information have the value of "0010", which indicates that the second number (N C2) is 2. The MAC CE 2 further includes 7-bit time information, and the 7-bit time information has a value of "1100100", indicating that the first time period is 100 ms. The MAC CE 2 further includes 1-bit GAP indication information, and the 1-bit GAP indication information has a value of "1", indicating that a measurement GAP needs to be started.

[0231] It should be noted that FIG. 8 only schematically shows that the MAC CE 2 includes 8-bit measurement identifiers, and the 8-bit measurement identifiers all have a value of "1", but the embodiments of the present application are not limited thereto. Alternatively, the MAC CE 2 can further include other numbers of measurement identifiers, and each bit can have a value of "0" or "1". The value of "0" of a bit indicates that measurement of a candidate cell corresponding to the bit is not needed, and accordingly, the 4-bit time information corresponding to the measurement identifier with the value of "0" in the MAC CE 2 can be 0, or the 4-bit time information corresponding to the measurement identifier with the value of "0" can not be carried, and the embodiments of the present application are not limited thereto.

[0232] It should be further noted that FIG. 8 only schematically shows that the MAC CE 2 includes 8-bit time information and 4-bit time information (such as the first time information or the second time information), but the embodiments of the present application are not limited thereto. Alternatively, the MAC CE 2 can further include other numbers of time information and / or time information, and the embodiments of the present application are not limited thereto.

[0233] It should be further noted that FIG. 8 only takes the first time information (used for indicating the first number N C1 ) corresponding to C1 (i.e., candidate cell 1) and the second time information (used for indicating the second number N C2 ) corresponding to C2 (i.e., candidate cell 2) in the MAC CE 2 as examples for introduction, but the embodiments of the present application are not limited thereto. Alternatively, the MAC CE 2 can further include time information (used for indicating at least one of N C3 ~ N C8 ) corresponding to at least one bit of C3~C8 (i.e., at least one of candidate cell 3~candidate cell 8), and the embodiments of the present application are not limited thereto.

[0234] It should be further noted that FIG. 8 only schematically shows that the MAC CE 2 includes 7-bit time information and 1-bit GAP indication information, but the embodiments of the present application are not limited thereto. Alternatively, the MAC CE 2 can further include other numbers of time information and / or GAP indication information, and the embodiments of the present application are not limited thereto.

[0235] S207. The terminal device sends a reporting message 3 to the network device, where the reporting message 3 is used to report the measurement result of the first candidate cell. Correspondingly, the network device receives the reporting message 3 from the terminal device.

[0236] S206 and S207 are repeatedly performed until the network device initiates a handover command to the terminal device or the terminal device receives the handover command from the network device.

[0237] S208. If the quality of the first candidate cell is measured to be better than the quality of the serving cell within the first time period, the terminal device sends a reporting message 4 to the network device, where the reporting message 4 is used to report that the quality of the first candidate cell is better than the quality of the serving cell. Correspondingly, the network device receives the reporting message 4 from the terminal device.

[0238] That is, if the terminal device determines that the triggering condition of the reporting LTM3 event is met, the terminal device reports the LTM3 event to the network device.

[0239] S209. If the quality of the first candidate cell is measured to be greater than or equal to a threshold value 3 and the quality of the serving cell is measured to be less than or equal to a threshold value 4 within the first time period, the terminal device sends a reporting message 5 to the network device, where the reporting message 5 is used to report that the quality of the first candidate cell is greater than or equal to the threshold value 3 and the quality of the serving cell is less than or equal to the threshold value 4. Correspondingly, the network device receives the reporting message 5 from the terminal device.

[0240] That is, if the terminal device determines that the triggering condition of the reporting LTM5 event is met, the terminal device reports the LTM5 event to the network device.

[0241] Optionally, the terminal device can obtain the threshold value 3 or the threshold value 4 in multiple ways.

[0242] In a possible implementation, the threshold value 3 or the threshold value 4 can be preconfigured.

[0243] For example, the threshold value 3 or the threshold value 4 can be preconfigured by the network device through an RRC message.

[0244] In another possible implementation, the terminal device can receive the threshold value 3 or the threshold value 4 sent by other devices (such as other terminal devices).

[0245] For example, the terminal device A can receive the threshold value 3 or the threshold value 4 sent by the terminal device B.

[0246] FIG. 9 is a schematic flow chart of a cell measurement method 300 provided by the embodiments of the present application, shown from the perspective of device interaction. As shown in FIG. 9, the method 300 can include S301-S306. The individual steps of the method 300 are described in detail below.

[0247] S301. The terminal device measures at least one candidate cell.

[0248] In a possible implementation, the terminal device performs one measurement on the at least one candidate cell in S301.

[0249] By way of example, the measurement result can include at least one of reference signal received power (RSRP), reference signal received quality (RSRQ), or signal to interference plus noise ratio (SINR).

[0250] S302. The terminal device sends a second reporting message to the network device, the second reporting message being used to indicate that measurement on a first candidate cell is needed, the at least one candidate cell including the first candidate cell, and the quality of the first candidate cell in the measurement result of the at least one candidate cell being greater than or equal to a first threshold value. Correspondingly, the network device receives the second reporting message from the terminal device.

[0251] Optionally, the terminal device can acquire the first threshold value in multiple ways.

[0252] In a possible implementation, the first threshold value can be preconfigured.

[0253] By way of example, the first threshold value can be preconfigured by the network device through an RRC message.

[0254] In another possible implementation, the terminal device can receive the first threshold value sent by other devices (such as other terminal devices).

[0255] By way of example, the terminal device A can receive the first threshold value sent by the terminal device B.

[0256] Optionally, the number of candidate cells whose quality in the measurement result of the at least one candidate cell is greater than or equal to the first threshold value can be multiple, such as including the first candidate cell and a third candidate cell, i.e., the terminal device reports that measurement on the first candidate cell and the third candidate cell is needed.

[0257] Optionally, the terminal device can report that measurement on the first candidate cell and the third candidate cell is needed in multiple ways.

[0258] In a possible implementation, the terminal device can report, through a reporting message, that measurement on the first candidate cell and the third candidate cell is required after the measurement on the at least one candidate cell is completed.

[0259] For example, the second reporting message is further used to indicate that measurement on the third candidate cell is required.

[0260] In another possible implementation, the terminal device can report, through a reporting message, that measurement on the first candidate cell is required after the measurement result of the first candidate cell is greater than or equal to the first threshold value, and report, through another reporting message, that measurement on the third candidate cell is required after the measurement result of the third candidate cell is greater than or equal to the first threshold value.

[0261] For example, S302 can include: when the measurement result of the first candidate cell in the at least one candidate cell is greater than or equal to the first threshold value, the terminal device sends the second reporting message to the network device; the method 300 can further include: when the measurement result of the third candidate cell in the at least one candidate cell is greater than or equal to the first threshold value, the terminal device sends a third reporting message to the network device, the third reporting message is used to indicate that measurement on the third candidate cell is required. Correspondingly, the network device receives the third reporting message from the terminal device.

[0262] Optionally, the first time period and / or the first threshold value are preconfigured.

[0263] S303. The terminal device performs measurement on the first candidate cell for a first number of times within a first time period based on the measurement result of the at least one candidate cell.

[0264] Optionally, the at least one candidate cell further includes a second candidate cell, and the method 300 can further include: the terminal device performs measurement on the second candidate cell for a second number of times within the first time period based on the measurement result of the at least one candidate cell, the quality of the second candidate cell in the measurement result of the at least one candidate cell is less than the first threshold value, and the first number of times is greater than the second number of times.

[0265] Optionally, the second number of times can be greater than or equal to 0.

[0266] In a possible implementation, when the number of the at least one candidate cell is greater than 1, if the second number of times is equal to 0, it can be understood that, within the first time period, the terminal device only needs to perform measurement on the candidate cell with good quality in the at least one candidate cell, and does not need to perform measurement on the candidate cell with poor quality in the at least one candidate cell. In this way, the number of measurement objects can be reduced, thereby reducing the energy consumption of the terminal device.

[0267] Optionally, in the embodiments of the present application, the terminal device can perform the high-frequency measurement on the candidate cell with good quality in the at least one candidate cell in the first time period. Alternatively, the terminal device can perform the measurement with a small cycle (i.e., high frequency) on the candidate cell with good quality in the at least one candidate cell in the first time period.

[0268] In another possible implementation, when the number of the at least one candidate cell is greater than 1, if the second frequency is greater than 0 and the first frequency is greater than the second frequency, it can be understood that the terminal device needs to perform the high-frequency measurement on the candidate cell with good quality in the at least one candidate cell and perform the low-frequency measurement on the candidate cell with poor quality in the at least one candidate cell in the first time period. In this way, the total number of cell measurements can be reduced, thereby reducing the energy consumption of the terminal device.

[0269] Optionally, in the embodiments of the present application, the terminal device can perform the high-frequency measurement on the candidate cell with good quality in the at least one candidate cell in the first time period. Alternatively, the terminal device can perform the measurement with a small cycle (i.e., high frequency) on the candidate cell with good quality in the at least one candidate cell in the first time period; or the terminal device can perform the low-frequency measurement on the candidate cell with poor quality in the at least one candidate cell, which can be replaced by the measurement with a large cycle (i.e., low frequency) on the candidate cell with poor quality in the at least one candidate cell.

[0270] Optionally, the method 300 can further include: if the terminal device determines that the first candidate cell and the serving cell belong to inter-frequency cells or inter-system cells, starting the measurement GAP. That is, the terminal device can determine whether to start the measurement GAP by itself.

[0271] S304. The terminal device sends a fourth reporting message to the network device, where the fourth reporting message is used to report the measurement result of the first candidate cell. Correspondingly, the network device receives the fourth reporting message from the terminal device.

[0272] S303 and S304 are repeatedly executed until the network device initiates a handover command to the terminal device or the terminal device receives the handover command from the network device.

[0273] S305. If the quality of the first candidate cell is better than that of the current serving cell in the first time period, the terminal device sends a fifth reporting message to the network device, where the fifth reporting message is used to report that the quality of the first candidate cell is better than that of the serving cell. Correspondingly, the network device receives the fifth reporting message from the terminal device.

[0274] That is, if the terminal device determines that the trigger condition of reporting the LTM3 event is met, the terminal device reports the LTM3 event to the network device.

[0275] S306. If the quality of the first candidate cell is greater than or equal to the threshold value 3 and the quality of the serving cell is less than or equal to the threshold value 4 in the first time period, the terminal device sends a sixth reporting message to the network device, where the sixth reporting message is used to report that the quality of the first candidate cell is greater than or equal to the threshold value 3 and the quality of the serving cell is less than or equal to the threshold value 4. Correspondingly, the network device receives the sixth reporting message from the terminal device.

[0276] That is, if the terminal device determines that the trigger condition of reporting the LTM5 event is met, the terminal device reports the LTM5 event to the network device.

[0277] Optionally, the terminal device can obtain the threshold value 3 or the threshold value 4 in multiple ways.

[0278] In a possible implementation, the threshold value 3 or the threshold value 4 can be preconfigured.

[0279] For example, the threshold value 3 or the threshold value 4 can be preconfigured by the network device through an RRC message.

[0280] In another possible implementation, the terminal device can receive the threshold value 3 or the threshold value 4 sent by other devices (such as other terminal devices).

[0281] For example, the terminal device A can receive the threshold value 3 or the threshold value 4 sent by the terminal device B.

[0282] Optionally, after receiving the cell measurement result reported by the terminal device (such as the reporting message 3 in the method 200 or the fourth reporting message in the method 300), the network device can further determine whether the terminal device needs to switch cells (i.e., switch from the current serving cell to a candidate cell), and if so, the network device sends a handover command to the terminal device.

[0283] Optionally, in the case of the CU-DU separation architecture of the network device, the handover command can be generated by the CU or the DU.

[0284] In a possible implementation, the DU determines and generates the handover command, i.e., the intra-DU cell handover (the source cell and the target cell belong to the same DU).

[0285] For example, the DU receives an LTM3 event or an LTM5 event reported by the terminal device, and determines whether to trigger a handover command based on the reported LTM3 event or LTM5 event.

[0286] In another possible implementation, a CU determines and generates a handover command, i.e., a cross-DU cell handover (the source cell and the target cell belong to different DUs under the same CU), and communication between the CU and the terminal device needs to be forwarded via the DU.

[0287] For example, the DU receives an LTM3 event or an LTM5 event reported by the terminal device, and sends report information to the CU, the report information including the quality of the serving cell and the quality of the candidate cell measured by the terminal device in a first time period; and the CU determines whether to trigger a handover command based on the report information.

[0288] FIG. 10 is a schematic flowchart of a cell measurement method 400 provided by the embodiments of the present application from the perspective of device interaction. As shown in FIG. 10, the method 400 can include S401 to S403. The following describes each step of the method 400 in detail.

[0289] S401. The network device sends first indication information to the terminal device, the first indication information being used to indicate that at least one candidate cell needs to be measured. Correspondingly, the terminal device receives the first indication information from the network device.

[0290] S402. The terminal device sends a first report message to the network device, the first report message being used to indicate the measurement result of the at least one candidate cell. Correspondingly, the network device receives the first report message from the terminal device.

[0291] S403. The network device sends second indication information to the terminal device based on the first report message, the second indication information being used to indicate that the first candidate cell needs to be measured for a first number of times in a first time period, the at least one candidate cell including the first candidate cell, and the quality of the first candidate cell in the measurement result of the at least one candidate cell being greater than or equal to a first threshold value. Correspondingly, the terminal device receives the second indication information from the network device.

[0292] In a possible implementation, the second indication information includes first number information and time information, the first number information being used to indicate the first number of times, and the time information being used to indicate the first time period.

[0293] In a possible implementation, the second indication information can further include at least one measurement identifier.

[0294] Optionally, the at least one candidate cell further comprises a second candidate cell, and the second indication information is further used to indicate that the second candidate cell is measured a second number of times within the first time period, the first number of times is greater than the second number of times, and a quality of the second candidate cell in the measurement result of the at least one candidate cell is less than the first threshold value.

[0295] In a possible implementation, the second indication information further comprises second number of times information, and the second number of times information is used to indicate the second number of times.

[0296] Optionally, the second indication information can be a MAC CE or DCI.

[0297] Optionally, the method 400 further comprises: the terminal device performs the first number of times of measurement on the first candidate cell within the first time period based on the second indication information.

[0298] Optionally, the method 400 further comprises: the terminal device performs the second number of times of measurement on the second candidate cell within the first time period based on the second indication information.

[0299] Optionally, the second number of times can be greater than or equal to 0.

[0300] In a possible implementation, when the number of the at least one candidate cell is greater than 1, if the second number of times is equal to 0, it can be understood that, within the first time period, the terminal device only needs to perform the first number of times of measurement on the candidate cell with good quality in the at least one candidate cell, and does not need to perform measurement on the candidate cell with poor quality in the at least one candidate cell. In this way, the number of measurement objects can be reduced, and thus the energy consumption of the terminal device is reduced.

[0301] Optionally, in the embodiment of the application, within the first time period, the terminal device performs the high number of times of measurement on the candidate cell with good quality in the at least one candidate cell can be replaced by that the terminal device performs the first period of measurement on the candidate cell with good quality in the at least one candidate cell.

[0302] In another possible implementation, when the number of the at least one candidate cell is greater than 1, if the second number of times is greater than 0, and the first number of times is greater than the second number of times, it can be understood that, within the first time period, the terminal device performs the high number of times of measurement on the candidate cell with good quality in the at least one candidate cell, and performs the low number of times of measurement on the candidate cell with poor quality in the at least one candidate cell. In this way, the total number of cell measurements can be reduced, and thus the energy consumption of the terminal device is reduced.

[0303] Optionally, in the embodiments of the present application, the terminal device performs the measurement of the candidate cell with good quality in the at least one candidate cell for a high number of times in the first time period, which can be replaced by the terminal device performing the measurement of the candidate cell with good quality in the at least one candidate cell for a small period (i.e., high frequency measurement); or the terminal device performs the measurement of the candidate cell with poor quality in the at least one candidate cell for a low number of times, which can be replaced by the terminal device performing the measurement of the candidate cell with poor quality in the at least one candidate cell for a large period (i.e., low frequency measurement).

[0304] Optionally, before the terminal device performs the measurement of the first candidate cell for the first number of times in the first time period, the terminal device can determine that the measurement GAP needs to be started in various ways.

[0305] In a possible implementation, the terminal device determines that the first candidate cell and the serving cell belong to inter-frequency cells or inter-system cells; and starts the measurement GAP. That is, the terminal device can determine by itself whether the measurement GAP needs to be started.

[0306] In another possible implementation, the second indication information is further used to indicate that the measurement GAP is started, and the terminal device starts the measurement GAP based on the second indication information. That is, the network device determines that the first candidate cell and the serving cell belong to inter-frequency cells or inter-system cells, and the terminal device can start the measurement GAP based on the indication of the network device.

[0307] Optionally, the method 400 can further include that the terminal device sends a reporting message 3 to the network device, and the reporting message 3 is used to report the measurement result of the first candidate cell. Correspondingly, the network device receives the reporting message 3 from the terminal device.

[0308] Optionally, the method 400 can further include that if the quality of the first candidate cell is better than the quality of the serving cell in the first time period, the terminal device sends a reporting message 4 to the network device, and the reporting message 4 is used to report that the quality of the first candidate cell is better than the quality of the serving cell. Correspondingly, the network device receives the reporting message 4 from the terminal device.

[0309] Optionally, the method 400 can further include that if the quality of the first candidate cell is greater than or equal to a threshold value 3 and the quality of the serving cell is less than or equal to a threshold value 4 in the first time period, the terminal device sends a reporting message 5 to the network device, and the reporting message 5 is used to report that the quality of the first candidate cell is greater than or equal to the threshold value 3 and the quality of the serving cell is less than or equal to the threshold value 4. Correspondingly, the network device receives the reporting message 5 from the terminal device.

[0310] It should be noted that the description of each step in the above method 400 can refer to the description of the corresponding step in the method 200, and details are not repeated here.

[0311] FIG. 11 is a schematic flowchart of a cell measurement method 500 provided by the embodiments of the present application from the perspective of device interaction. As shown in FIG. 11, the method 500 can include S501-S502. The details of each step of the method 500 are described below.
