[0110] In this disclosure, "at least one" means one or more, and "multiple" means two or more.

[0111] The term "connection" in this disclosure refers to various connection methods, such as direct connection or indirect connection, to achieve communication between devices. This disclosure does not limit the scope of the term.

[0112] First, the terminology used in the embodiments of this disclosure will be explained:

[0113] gNB-Central Unit (CU): A logical node used to carry gNB's RRC, Service Data Adaptation Protocol (SDAP), and Packet Data Convergence Protocol (PDCP) protocols, or to carry the RRC and PDCP protocols of an evolved (en) gNB. The gNB-CU can be used to control the operation of one or more gNB-Distributed Units (DUs). The gNB-CU terminates the F1 interface connected to the gNB-DU.

[0114] gNB-DU: A logical node used to carry the Radio Link Control (RLC), Medium Access Control (MAC), and Physical Layer (PHY) layers of a gNB or en-gNB. Its operation is controlled by the gNB-CU. One gNB-DU can support one or more cells. A cell is supported by only one gNB-DU. The gNB-DU terminates the F1 interface connected to the gNB-CU.

[0115] In related technologies, terminal devices can perform measurement processing based on measurement configuration information sent by network devices and send the measurement results back to the network devices. However, in current related technologies, the measurement objects corresponding to multiple measurement configuration information may overlap, causing the terminal device to repeatedly measure these overlapping measurement objects, resulting in excessive measurement overhead for the terminal device.

[0116] For ease of understanding, the application scenarios applicable to the embodiments of this disclosure will be described below with reference to Figure 1A.

[0117] Figure 1A is a schematic diagram of an application scenario provided by an embodiment of this disclosure. Referring to Figure 1A, it includes a terminal device 101 and a network device 102. The terminal device 101 can be a mobile phone, tablet computer, computer, etc. The network device 102 can be a base station. In NR, in response to the terminal device 101 being in RRC connected state, during the process of the terminal device 101 moving from one cell to another, the terminal device 101 can send a measurement report to the network device 102. The network device 102 can determine whether to perform cell handover for the terminal device based on the measurement report sent by the terminal device 101.

[0118] Figure 1B is a schematic diagram of a cell handover process provided in an embodiment of this disclosure. Referring to Figure 1B, the cell handover process may include the following steps:

[0119] S101b: The network device sends measurement configuration information to the terminal device.

[0120] Measurement configuration information can be used to instruct terminal equipment how to measure a target object, which can be a reference signal and / or a cell.

[0121] It should be noted that in some embodiments, the terms "measurement target" and "measurement object" can be used interchangeably.

[0122] A communication network architecture can include three layers: Layer 1 (L1), which is the physical layer; Layer 2 (L2), which is the data link layer; and Layer 3 (L3), which is the network layer. In mobility management, L1 / L2 can be beam-based measurement management, typically managed through physical layer signaling or MAC signaling; while L3 can be cell-level mobility management, primarily managed through RRC signaling. Terminal equipment measurements typically include both L1 and L3 measurements. For example, L1 measurements may include signal strength measurement, signal-to-noise ratio (SNR), and bit error rate (BER) measurement; L3 measurements may include neighbor cell or serving cell measurements for cell reselection and handover, etc. L3 measurements can filter the obtained L1 beam-based measurement results to obtain cell-level measurement results.

[0123] In some embodiments, the network device can configure measurement configuration (MeasConfig) information for L3 measurement for the terminal device. The MeasConfig information may include: measurement object (MeasObject); measurement reporting configuration information; and measurement identification information (measurement id).

[0124] Network devices can configure measurement objects based on frequency points. The measurement objects can include measurement reference information configured on a certain frequency point. The measurement reference information can include at least one of the following: at least one Synchronization Signal Block (SSB), Channel State Information-Reference Signal (CSI-RS) information, Offset information, SSB-based RRM measurement timing configuration (SMTC), and a list of cells that are allowed or not allowed to be measured.

[0125] Measurement reporting configuration information can be used to indicate the conditions that trigger the terminal device to send a measurement report. Measurement reporting configuration information may include at least one of the following: event-triggered reporting configuration information; period-triggered reporting configuration information.

[0126] Event-triggered reporting configuration information may include: event identifier (ID), event threshold, quality (quantity), and number of reports.

[0127] Measurement identification information (measurement id) can be used to associate measurement objects and measurement reporting configuration information.

[0128] S102b: The terminal device sends a measurement report to the network device.

[0129] In some embodiments, the terminal device can determine an L3 measurement event based on measurement configuration information. This L3 measurement event can be used to trigger the terminal device to perform L3 measurement and send an L3 measurement report to the network device.

[0130] L3 measurement events may include at least one of the following:

[0131] Event A1: The signal quality of the serving cell is higher than the specified signal quality threshold.

[0132] Event A2: The signal quality of the serving cell is lower than the specified signal quality threshold.

[0139] Conditional event A3: The signal quality of the candidate cell for conditional reconfiguration is higher than that of the primary cell / primary / secondary cell by a specified offset.

[0140] Conditional event A4: The signal quality of the candidate cell for conditional reconfiguration is higher than the specified signal quality threshold.

[0141] Conditional event A5: The signal quality of PCell / PSCell is lower than the specified signal quality threshold 1, and the signal quality of the conditional reconfiguration candidate cell is higher than the specified signal quality threshold 2.

[0142] Conditional event D1: The distance between the UE and reference location 1 is greater than the configured reference distance threshold 1, and the distance between the UE and reference location 2 of the conditional reconfiguration candidate cell is less than the configured reference distance threshold 1.

[0143] Conditional event D2: The distance between the serving unit's mobile reference location, determined by the mobile reference location broadcast in SIB19 and its corresponding satellite ephemeris and epoch time, and the UE is greater than the configured reference distance threshold 1; and the distance between the mobile reference location, determined by the candidate cell's reference location and its corresponding satellite ephemeris and epoch time, provided in the associated measurement object (MeasObjectNR), and the UE is less than the configured reference distance threshold 2.

[0146] Event X2: The signal quality of the L2 U2N relay UE in the serving cell is lower than the specified signal quality threshold.

[0147] For event I1, the measurement report event is based on the measurement results of Channel State Information Reference Signal Received Power (CLI), which can be determined based on Sounding Reference Signal-Reference Signal Received Power (SRS-RSRP) or Channel State Information-Received Signal Strength Indicator (CLI-RSSI).

[0148] Event I1: Interference exceeds the specified threshold.

[0149] Reporting events related to the altitude of an airborne UE are labeled HN, where N can take values ​​of 1 and 2.

[0158] S103b: Based on the measurement report, the network equipment determines whether to perform cell handover for the terminal equipment.

[0159] In response to determining that a cell handover should be performed on the terminal device, the network device may also execute step S104b:

[0160] S104b: The network device sends a handover command to the terminal device.

[0161] The handover command can be used to instruct a terminal device to hand over from the current cell to the target cell.

[0162] In some embodiments, L1 / L2-triggered mobility (LTM) can be based on L1 measurement results and use L2 signaling to perform a handover procedure, which may include a Medium Access Control (MAC) control element (CE).

[0163] Figure 1C is a schematic diagram of an LTM process provided in an embodiment of this disclosure. Referring to Figure 1C, the LTM process may include the following stages: LTM preparation stage, pre-synchronization stage, LTM execution stage, and LTM completion stage, wherein:

[0164] The LTM preparation phase may include the following steps S101c to S104c:

[0165] S101c: The terminal device sends a measurement report to the network device.

[0166] In response to the terminal device being in RRC connection state, the terminal device can execute step S101c.

[0167] S102c, the network device determines the configuration information of LTM candidate cells based on the measurement report.

[0168] S103c: The network device sends an RRC reconfiguration message to the terminal device.

[0169] The RRC reconfiguration message may include configuration information for LTM candidate cells, which is used to configure the LTM candidate cells of the terminal device.

[0170] S104c: The terminal device sends an RRC reconfiguration complete message to the network device.

[0171] The terminal device can perform an RRC reconfiguration operation based on the configuration information of the LTM candidate cell, and send an RRC reconfiguration completion message to the network device after the reconfiguration is completed.

[0172] Before performing cell handover, network devices may request terminal devices to continue pre-synchronization with one or more candidate cells. The network device may trigger the pre-synchronization operation via a Physical Downlink Control Channel (PDCCH) order. The pre-synchronization phase may include the following steps S105c and S106c:

[0173] S105c: The network device sends the PDCCH command to the terminal device.

[0174] S106c: The terminal device performs a pre-synchronization operation according to the PDCCH instruction.

[0175] Early synchronization operations can include uplink synchronization with candidate cells and downlink synchronization with candidate cells.

[0176] The PDCCH command can include non-contention-based preamble information of the target candidate cell. The terminal device can send the preamble to the target candidate cell without waiting to receive a Random Access Response (RAR). The network device obtains the timing advance (TA) of the terminal device by receiving the preamble. This TA value can be notified to the terminal device's current serving cell by the target candidate cell.

[0177] The LTM execution phase may include the following steps S107c~S110c:

[0178] S107c: The terminal device sends the L1 measurement results to the network device.

[0179] Network devices (gNB-DU) can instruct terminal devices to periodically report L1 measurement results, or instruct terminal devices to report L1 measurement results at a certain time.

[0180] S108c, the network device, determines the target cell for handover based on the L1 measurement results.

[0181] S109c: The network device sends a cell handover command to the terminal device.

[0182] Cell handover commands can be carried in MAC CE.

[0183] Cell handover instructions may include a target configuration identifier, as well as: TA information, Transmission Configuration Indicator (TCI) state ID, and Uplink (UL) TCI state ID (selected SSB).

[0184] S110c: The terminal device performs a cell handover operation to switch from the current cell to the target cell.

[0185] In response to the cell handover command including TA information, the terminal device does not need to perform Random Access Channel (RACH) operation in the target cell; that is, the terminal device does not need to perform the RACH-less procedure, but instead waits for the target cell to dynamically schedule the terminal device to send a completion message via PDCCH. Alternatively, the terminal device can determine the CG resource associated with the beam indication received in the cell handover command from the pre-configured grant (CG) resources, and send uplink information based on the CG resource. This uplink information may include the transmission data sent by the terminal device to the network device. After determining that the network device has received the first transmission data, the terminal device can consider the LTM handover successful.

[0186] In response to the fact that the cell handover command does not include TA information, the terminal device needs to perform a RACH process in the target cell to complete the synchronization with the target cell and obtain the TA and beam information of the target cell.

[0187] The LTM completion phase may include step S111c:

[0188] S111c: The terminal device sends an LTM handover completion message to the network device.

[0189] In some embodiments, the LTM handover completion message can be called an RRC reconfiguration complete message (RRCReconfigurationComplete), used to indicate that the LTM handover of the terminal device is complete. For RACH-less procedures, the terminal device can send the first transmission data to the network device, which can be the LTM handover completion message. After determining that the network device has received the first transmission data, the LTM handover can be considered successful. For procedures requiring RACH, the terminal device can consider the LTM handover successful after determining that the RACH procedure has been completed. For RACH-less handover processes, the terminal device cannot execute the random access procedure before determining that the LTM handover is successful.

[0190] In the LTM process, the terminal device can periodically report L1 measurement results to the network device, or the network device can send an indication message to the terminal device to trigger the terminal device to report L1 measurement results to the network device. To avoid wasting reporting resources by the terminal device repeatedly reporting L1 measurement results when the handover conditions are not met, the network device can configure an L1 measurement event for the terminal device, which is used to trigger the terminal device to report L1 measurement results.

[0191] In some embodiments, an L1 measurement event may include at least one of the following:

[0192] Event LTM2: The serving cell’s beam quality is below the specified signal quality threshold.

[0193] Event LTM3: The beam quality of the candidate cell is higher than that of the serving cell by a specified offset.

[0194] Event LTM4: The beam quality of the candidate cell is higher than the specified signal quality threshold.

[0195] Event LTM5: The serving cell’s beam quality is below the signal quality threshold 1, and the candidate cell’s beam quality is above the signal quality threshold 2.

[0196] LTM within a single CU (intra-CU) and LTM between CUs (inter-CU) can be configured uniformly through common CSI resource configuration information. This common CSI resource configuration can be configured based on the CSI reporting mechanism. Here, "intra-CU" refers to LTMs within the same CU, and "inter-CU" refers to LTMs between different CUs. Optionally, the common CSI resource configuration may include LTM-CSI-ResourceConfig, which may include LTM-SSB-ResourceConfig. This LTM-SSB-ResourceConfig may include an SSB index and an LTM candidate cell identifier. The LTM candidate cell identifier is used to identify LTM candidate cells, and the SSB index is used to determine the LTM-SSB-configuration information. Optionally, the LTM-CSI-ResourceConfig may also include a CSI-RS index, which is used to determine the LTM-CSIRS-configuration information.

[0197] Compared to the configuration method of L3 measurement objects in L3 measurement, L1 measurement objects in LTM can be configured through LTM-CSI-ResourceConfig. L1 measurement objects can include: SSB or CSI-RS reference signal information of candidate cells. The SSB of the candidate cell can be an SSB or an SSB resource set, which can include multiple different SSB resources. The CSI-RS reference signal information can include CSI-RS resource sets, which can include multiple different CSI-RS resources.

[0198] The CSI measurement configuration information (CSI-MeasConfig) of the serving cell can be configured with LTM-CSI-ReprotingConfig, which includes report configuration information, a report configuration information identifier (Report Config ID), and an LTM-CSI-ResourceConfig ID. The Report Config ID identifies the report configuration information and can include the reporting method for measurement reports, which can be either periodic reporting or event-triggered reporting. This report configuration information can also include resources used for measurement report reporting, such as the Physical Uplink Control Channel (PUCCH) and the Physical Uplink Shared Channel (PUSCH). The LTM-CSI-ResourceConfig ID identifies the LTM-CSI-SSB-Resource Configuration information, i.e., the resource information used for this report configuration.

[0199] LTM supports subsequent handovers, meaning that after a handover, the LTM configuration information on the network device does not need to be deleted or reconfigured. The network device can continue to determine whether to initiate a handover based on the candidate cell information in the previously configured LTM configuration. Because the common CSI resource configuration in the LTM configuration remains unchanged, the measurement objects of the terminal device are the same regardless of which serving cell it hands over to. However, as the serving cell of the terminal device changes, the measurement objects that the terminal device needs to measure may differ. If the candidate cell information in the previously configured LTM configuration is continued to be used, the terminal device may still perform measurements on some objects that do not need to be measured after the serving cell handover, leading to increased power consumption for measurement.

[0200] In some scenarios (e.g., 5G NR), the Layer 3 measurement reporting mechanism and the CSI measurement reporting mechanism for RRM measurements are configured separately. However, Layer 3 measurements and CSI measurements may have overlapping measurement objects, which may include reference signals and / or cells. This causes network devices to repeatedly configure the measurement configuration information for these measurement objects and send this information to terminal devices, resulting in excessive configuration signaling overhead. Furthermore, terminal devices may repeatedly perform measurements and reports on these overlapping measurement objects, leading to excessive measurement overhead for the terminal devices. Therefore, in the design of future new systems (e.g., 6G), a unified measurement reporting and handover mechanism needs to be considered to reduce measurement overhead.

[0201] In this embodiment, the terminal device can perform measurements on the first measurement group based on indication information or in response to the fulfillment of a first preset condition. The indication information can be used to instruct the measurement of the first measurement group, and the first preset condition can be a condition for performing the measurement of the first measurement group. In this way, when the terminal device needs to measure the first measurement group, it does not need to receive different measurement configuration information, avoiding repeated measurements and reporting of at least one reference signal and / or at least one cell in the first measurement group based on different measurement configuration information. This helps reduce the measurement and reporting overhead of the terminal device and saves its resources. Simultaneously, the network device can flexibly and quickly perform unified measurement configuration for at least one reference signal and / or at least one cell in the first measurement group, without needing to configure separate measurement reporting and handover mechanisms for the same measurement object (reference signal and / or cell). This facilitates a unified measurement reporting and handover mechanism and reduces measurement overhead.

[0202] The method disclosed herein will now be described through specific embodiments. It should be noted that the following embodiments may exist independently or in combination with each other; identical or similar content will not be repeated in different embodiments.

[0203] Figure 2 is a schematic flowchart of one of the measurement methods provided in this disclosure. Referring to Figure 2, the method may include:

[0204] S201. The network device sends instruction information to the terminal device.

[0205] The terminal device receives instruction information, which can be used to instruct the first measurement group to be measured.

[0206] In some embodiments, the indication information may be carried in the MAC CE or the Downlink Control Information (DCI). In other words, the indication information may be included in the MAC CE, or the indication information may be included in the DCI. Alternatively, the indication information may also be carried in Layer 1 or Layer 2 signaling.

[0207] By carrying the instruction information in MAC CE or DCI, network devices can send instruction information more easily, flexibly, and quickly.

[0208] It should be noted that in some embodiments, the instruction information may also be referred to as an activation command.

[0209] Optionally, the indication information may include the identifier of the measurement group (groupId), and may also include information about the measurement object, which may be at least one reference signal and / or at least one cell. The information about the measurement object may include at least one of the following: the resource configuration information identifier (resourceConfigId) associated with the measurement object, the cell identifier (cell id), the physical cell identity (PCI), and the configuration information identifier (configId) of the candidate cell.

[0210] The first measurement group may include at least one reference signal identifier and / or at least one cell identifier.

[0211] At least one reference signal may include at least one of the following: SSB, CSI-RS, Sounding Reference Signal (SRS), or reference signal. It is understood that at least one reference signal may also include other reference signals used for measurement by the terminal device; embodiments of this disclosure do not limit the number and type of reference signals.

[0212] At least one cell may include at least one of the following: the terminal device’s current serving cell, neighboring cell, candidate cell, PCell, PSCell, SCell, or SpCell.

[0213] In some embodiments, the reference signals and / or cells in the first measurement group may satisfy at least one of the following: they correspond to the same measurement purpose; they have the same energy-saving information; and they correspond to the same candidate cell information.

[0214] In this embodiment, the network device can divide at least one reference signal and / or at least one cell into a first measurement group according to measurement requirements (or measurement scenarios). The measurement requirements (or measurement scenarios) may include one or more of the following: measurement purpose, energy-saving information, or candidate cell information. In this way, the network device can quickly and flexibly configure at least one reference signal and / or at least one cell for the terminal device based on the terminal device's actual measurement requirements or measurement scenarios by instructing the measurement group, without needing to configure each reference signal and / or each cell for the terminal device by configuring multiple measurement configuration information. This helps reduce the overhead of measurement configuration and measurement configuration information transmission for the network device.

[0215] Measurement objectives may include at least one of the following: synchronization with the target cell; radio resource management (RRM) measurement of the target cell; CSI measurement of the target cell; radio link management (RLM) measurement of the target cell; beam management. It is understood that measurement objectives may also include other purposes for terminal device measurements, and this disclosure does not limit the measurement objectives.

[0216] The target cell may include at least one of the following: the terminal device's current serving cell, neighboring cell, candidate cell, PCell, PSCell, SCell, or SpCell.

[0217] RRM measurements may include, but are not limited to, L1 or L3 measurements.

[0218] RLM measurements can be used to determine the communication quality of a wireless link. For example, RRM and RLM measurements may include at least one of the following: Reference Signal Received Power (RSRP) measurement, Reference Signal Received Quality (RSRQ) measurement, Signal-to-Interference Plus Noise Ratio (SINR) measurement, etc. Specifically, RSRP measurement is used by the terminal device to measure the power intensity of the reference signal received from the network device; RSRQ measurement is used by the terminal device to measure the signal quality of the reference signal received from the network device; and SINR measurement is used by the terminal device to measure the SINR.

[0219] Beam management can include beam selection, beam switching, beam measurement and reporting, or beam optimization.

[0220] In this embodiment of the disclosure, multiple measurement objectives can be provided so that the network device can flexibly configure the corresponding measurement objectives for each measurement group according to the measurement needs (or measurement scenarios) of each measurement group.

[0221] Energy-saving information may include at least one of the following: energy-saving status, or non-energy-saving status; the measurement period corresponding to the energy-saving status, or the measurement period corresponding to the non-energy-saving status.

[0222] Understandably, fewer cells can be activated at night than during the day. In this case, the number of measurement targets configured during the day and night can differ. For example, at night, to save energy, fewer measurement targets can be configured for the terminal device. In this case, the terminal device is in energy-saving mode, and the measurement period corresponding to energy-saving mode is 0:00 to 6:00. During the day, to achieve more accurate measurements, more measurement targets can be configured for the terminal device. In this case, the terminal device is in non-energy-saving mode, and the measurement period corresponding to non-energy-saving mode is 6:01 to 24:00.

[0223] In this embodiment of the disclosure, the energy-saving information corresponding to the first measurement group can be flexibly indicated by the energy-saving state and / or the measurement period corresponding to the energy-saving state, and the non-energy-saving state and / or the measurement period corresponding to the non-energy-saving state, so that the energy-saving information can be applied to various configuration scenarios.

[0224] The candidate cell information may include at least one of the following: the identifier of the candidate cell; the candidate cell meeting the second preset condition.

[0225] The identifier for a candidate cell can be the name or index of the candidate cell.

[0226] In this embodiment of the disclosure, the information of the cell to be measured or the information of the auxiliary cell to be measured can be flexibly configured by the identifier of the candidate cell and / or the candidate cell meeting the second preset condition, so as to flexibly adjust the candidate cell information as the candidate cell changes, so as to be suitable for various measurement configuration scenarios.

[0227] The second preset condition may include at least one of the following: advance synchronization condition; measurement reporting condition; switching trigger condition.

[0228] The advance synchronization conditions can be the conditions under which the terminal device synchronizes with the candidate cell in advance. The advance synchronization conditions can include uplink synchronization conditions for uplink synchronization processing with the candidate cell, and downlink synchronization conditions for downlink synchronization processing with the candidate cell.

[0229] The measurement reporting conditions can be the conditions for the terminal device to report measurements to the candidate cell. The measurement reporting conditions can include L3 measurement events and L1 measurement events. It should be noted that the content of the L3 measurement event can refer to the content of the L3 measurement event in step S102b, and the L1 measurement event can include the L1 measurement event in S111c, which will not be elaborated here.

[0230] The handover trigger condition can be the condition that triggers the terminal device to hand over to the candidate cell.

[0231] In this embodiment of the disclosure, a variety of second preset conditions can be selected so that the network device can flexibly configure corresponding candidate cell information for each measurement group according to the measurement needs (or measurement scenarios) of each measurement group.

[0232] In this embodiment of the disclosure, the network device may group multiple reference signals and / or multiple cells according to at least one of the following: measurement purpose, energy saving information or candidate cell information, to obtain at least one measurement group, wherein the at least one measurement group may include a first measurement group.

[0233] It is understood that, for any one of the measurement groups in at least one measurement group, the reference signals and / or cells in that measurement group satisfy at least one of the following: the corresponding measurement objectives are the same; the energy-saving information is the same; and the corresponding candidate cell information is the same.

[0234] S202. The terminal device performs measurements on the first measurement group according to the instruction information or in response to the fulfillment of the first preset condition.

[0235] The first preset condition can be the condition for measuring the first measurement group.

[0236] The network device can configure corresponding preset conditions for each measurement group, which are used to trigger the terminal device to perform measurements on the measurement group. For example, the network device can configure a corresponding first preset condition for the first measurement group.

[0237] In some embodiments, the terminal device can obtain configuration information sent by the network device and determine the first measurement group and the first preset conditions based on the configuration information. It should be noted that the process of the terminal device obtaining the configuration information will be described in detail in the embodiment shown in Figure 3.

[0238] It is understandable that, in response to the first preset condition corresponding to the first measurement group being met, the terminal device may perform a measurement on the first measurement group; in response to the first preset condition corresponding to the first measurement group not being met and no indication information being obtained, the terminal device may temporarily not perform a measurement on the first measurement group.

[0239] In some embodiments, the terminal device may also send the measurement results of the first measurement group to the network device so that the network device can determine whether to perform a handover process based on the measurement results.

[0240] In some embodiments, the indication information may include an identifier of a first measurement group. The terminal device can determine the first measurement group based on the identifier and configuration information of the first measurement group in the indication information, perform measurements on the first measurement group, and send a measurement report of the first measurement group to the network device.

[0241] In some embodiments, the indication information may further indicate the measurement requirements corresponding to the first measurement group, which may include at least one of the following: measurement purpose, energy-saving indication information, or candidate cell information. The terminal device can find the first measurement group corresponding to the measurement requirements indicated in the indication information in the configuration information and perform measurements on the first measurement group.

[0242] For example, the indication information may include energy-saving indication information, which can be used to instruct the terminal device to measure the measurement group in energy-saving state (or non-energy-saving state). In response to the state of the first measurement group in at least one measurement group being energy-saving state (or non-energy-saving state), the terminal device can measure and report the first measurement group according to the energy-saving indication information.

[0243] For example, the indication information may include candidate cell identifiers. The terminal device can determine the corresponding measurement group in the configuration information based on the candidate cell identifiers in the indication information, and then perform measurements on the measurement group.

[0244] For example, the indication information can be used to indicate that the measurement conditions for the first measurement group are that the candidate cell meets the second preset condition. Based on this indication information, the terminal device, in response to determining that the candidate cell meets the second preset condition, performs measurements on the measurement group corresponding to the candidate cell.

[0245] Optionally, in addition to including the identifier of the first measurement group and / or the measurement requirements corresponding to the first measurement group in the indication information, the indication information may also carry a measurementid. This measurementid can be used to associate a measurement object with measurement reporting configuration information. The measurement object can be a measurement object in a public resource configuration or a measurement object in a resource group configuration. After receiving the indication information, the terminal device can determine the first measurement group based on the identifier of the first measurement group and / or the measurement requirements corresponding to the first measurement group. The first measurement group may include at least one measurement object, which can be a reference signal and / or a cell. The terminal device can further filter the measurement objects in the first measurement group based on the measurementid to find the measurement object associated with that measurementid, and determine the measurement reporting configuration information of the measurement object associated with that measurementid as the configuration information for this measurement report. In this way, the measurement object and the corresponding measurement reporting configuration information can be determined more accurately.

[0246] In some embodiments, the terminal device can determine a measurement group or resource set for measurement based on indication information. The measurement group or resource set may include different measurement quantities or reference signal types; for example, the measurement type may be SSB or CSI-RS. After determining the measurement group or resource set, the terminal device can further filter the measurement objects within that measurement group or resource set based on the measurement type or reference signal type consistent with the current serving cell to more accurately select the measurement objects. It should be noted that the measurement type or reference signal type consistent with the current serving cell can be pre-agreed upon by the network device and the terminal device, or it can be pre-configured by the network device for the terminal device.

[0247] In some embodiments, the terminal device may further determine whether its own conditions meet the first preset conditions, and in response to determining that the first preset conditions are met, automatically perform measurements on the first measurement group and send a measurement report of the first measurement group to the network device.

[0248] For example, the first preset condition could be that the measurement purpose of the terminal device is the same as the measurement purpose of the first measurement group, where the measurement purpose of the first measurement group is "to perform RRM measurement on the target cell". When the terminal device is performing a handover procedure, it needs to perform RRM measurement on the target cell. In this case, the measurement purpose of the terminal device is the same as the measurement purpose of the first measurement group, and the terminal device can trigger a measurement reporting operation for the first measurement group. It should be noted that RRM measurement can be either L1 or L3 measurement, which can be further determined based on network instructions, measurement reporting configuration, or the ongoing mobility procedure.

[0249] For example, the first preset condition can be that the energy-saving information of the terminal device is the same as the energy-saving information corresponding to the first measurement group. The energy-saving information of the first measurement group can include: the measurement state is energy-saving state, and / or the measurement time period corresponding to the energy-saving state is 0:00 to 6:00. In response to the terminal device's measurement state being energy-saving state, and / or in response to the terminal device's measurement time being between 0:00 and 6:00, the energy-saving information of the terminal device is the same as the energy-saving information of the first measurement group, and the terminal device can report the measurement of the first measurement group.

[0250] For example, the first preset condition may be that the candidate cell information of the terminal device is the same as the candidate cell information corresponding to the first measurement group. The candidate cell information corresponding to the first measurement group may include: candidate cell 1, and / or, the candidate cell meets the second preset condition. The second preset condition may include at least one of the following: advance synchronization condition; measurement reporting condition; handover triggering condition. In response to at least one of the following: handover to candidate cell 1; meeting the advance synchronization condition for candidate cell 1; meeting the measurement reporting condition for candidate cell 1; meeting the handover triggering condition for candidate cell 1; the candidate cell information of the terminal device is the same as the candidate cell information corresponding to the first measurement group, the terminal device may perform measurement reporting for the first measurement group. It should be noted that the first measurement group here may be one other cell or a group of other cells corresponding to the candidate cell, and a group of other cells may include two or more other cells.

[0251] For example, the first preset condition may include: the measurement purpose of the terminal device is the same as the measurement purpose corresponding to the first measurement group, and the candidate cell information of the terminal device is the same as the candidate cell information corresponding to the first measurement group. In response to the measurement purpose of the first measurement group being "to perform RRM measurement on the target cell," the candidate cell information corresponding to the first measurement group may include: candidate cell 1. When the terminal device needs to perform RRM measurement on candidate cell 1, the terminal device can report the measurement to the first measurement group.

[0252] Furthermore, the first preset condition may also include: the measurement purpose of the terminal device is the same as the measurement purpose corresponding to the first measurement group; the energy-saving information of the terminal device is the same as the energy-saving information corresponding to the first measurement group; and the candidate cell information of the terminal device is the same as the candidate cell information corresponding to the first measurement group. Responding to the measurement purpose of the first measurement group being "to perform RRM measurement on the target cell," the energy-saving information of the first measurement group may include: energy-saving status, and the candidate cell information corresponding to the first measurement group may include: candidate cell 1. When the terminal device needs to perform RRM measurement on candidate cell 1 at 5:00, and 5:00 falls within the measurement period corresponding to the energy-saving status (0:00~6:00), in this case, the terminal device meets the first preset condition, and the terminal device can report the measurement to the first measurement group.

[0253] The measurement method provided in this disclosure allows a terminal device to perform measurements on a first measurement group based on indication information or in response to the fulfillment of a first preset condition. This eliminates the need for the terminal device to receive different measurement configuration information when measurements of the first measurement group are required. It avoids the terminal device repeatedly measuring and reporting at least one reference signal and / or at least one cell in the first measurement group based on different measurement configuration information, thereby reducing the measurement and reporting overhead of the terminal device and saving its resources.

[0254] Figure 3 is a second schematic flowchart of the measurement method provided in this embodiment. Referring to Figure 3, the method may include:

[0255] S301. The network device sends configuration information to the terminal device.

[0256] In some embodiments, network devices can configure LTM for PCells and PSCells, enabling terminal devices to perform L1-based measurement reporting and handover for PSCells. However, under Carrier Aggregation (CA) configuration, as the target cell changes, the Scell ​​cell group performing CA operations with the target cell also changes, which changes the measurement object. Since LTM currently does not support flexible configuration of measurement objects, it does not support pre-measurement or CSI activation of Scells, thus not supporting L1-based measurement reporting and handover for SSCells by terminal devices.

[0257] In this embodiment, the network device can divide multiple reference signals and / or multiple cells into at least one measurement group according to the measurement requirements (or measurement scenarios) of the terminal device. Each measurement group may include at least one reference signal and / or at least one cell, and the at least one reference signal and / or at least one cell in each measurement group may correspond to the same measurement requirements (or measurement scenarios). By configuring at least one reference signal and / or at least one cell with the same measurement requirements (or measurement scenarios) into a measurement group, the network device can flexibly and easily instruct the terminal device to perform measurements on the measurement group corresponding to the current measurement requirements (or current measurement scenarios) according to the current measurement requirements (or current measurement scenarios) of the terminal device, without having to configure each reference signal and / or each cell to the terminal device by configuring multiple measurement configuration information. This helps to reduce the overhead of measurement configuration and measurement configuration information transmission for the network device. Furthermore, this method enables LTM to support flexible configuration of measurement objects (reference signals and / or cells), thereby enabling the terminal device to support L1-based measurement reporting and handover of SCells, and to flexibly adjust the target secondary cells or cell groups to be measured as the primary cell changes, making the measurement configuration of secondary cells or cell groups by the terminal device more flexible.

[0258] After dividing at least one measurement group, the network device can generate configuration information, which may include: the identifier of at least one measurement group, and at least one reference signal identifier and / or at least one cell identifier included in the measurement group.

[0259] The identifier for a measurement group can be used to identify the corresponding measurement group. The identifier for a measurement group can be the name or index of the measurement group.

[0260] A reference signal identifier can be used to identify a reference signal, which can be the name or index of the reference signal.

[0261] A cell identifier can be used to identify a cell; the cell identifier can be the cell's name or index.

[0262] In some embodiments, the configuration information may further include: preset conditions corresponding to the measurement group.

[0263] Preset conditions can be used to trigger the terminal device to perform measurements on the measurement group. These preset conditions may include at least one of the following: the measurement purpose of the terminal device is the same as the measurement purpose corresponding to the first measurement group; the energy-saving information of the terminal device is the same as the energy-saving information corresponding to the first measurement group; the candidate cell information of the terminal device is the same as the candidate cell information corresponding to the first measurement group.

[0264] It should be noted that the specific content of the measurement purpose, energy-saving information and candidate cell information in this step can be referred to the specific content of the measurement purpose, energy-saving information and candidate cell information in step S201, and will not be repeated here.

[0265] S302. The network device sends instruction information to the terminal device.

[0266] It should be noted that the content of the instruction information in this step can be referred to the content of the instruction information in step S201, and will not be repeated here.

[0267] In some embodiments, the network device may periodically send indication information to the terminal device; or, in response to determining that the terminal device meets a first preset condition, the network device may send indication information to the terminal device; or, in response to needing to instruct the terminal device to perform measurements on the first measurement group, the network device may send indication information to the terminal device.

[0268] S303. The terminal device performs measurements on the first measurement group according to the instruction information or in response to the fulfillment of the first preset condition.

[0269] It should be noted that the specific execution process of step S303 can be referred to the specific execution process of step S202, and will not be repeated here.

[0270] The measurement method provided in this disclosure allows a network device to configure a terminal device with at least one measurement group identifier, at least one reference signal identifier and / or at least one cell identifier included in the measurement group, and preset conditions corresponding to the measurement group, facilitating subsequent measurement configuration of the terminal device. The network device can also send instruction information to the terminal device to instruct it to measure the first measurement group in at least one measurement, simplifying the configuration of measurement reporting for the terminal device. The terminal device can perform measurements on the first measurement group based on the instruction information or in response to meeting the first preset conditions corresponding to the first measurement group. This eliminates the need for the terminal device to receive different measurement configuration information when measuring the first measurement group, avoiding repeated measurements and reporting of at least one reference signal and / or at least one cell in the first measurement group based on different measurement configuration information. This reduces measurement and reporting overhead and saves terminal device resources.

[0271] Figure 4 is a third schematic flowchart of the measurement method provided in this embodiment of the present disclosure. Referring to Figure 4, the method may include:

[0272] S401. The network device sends configuration information to the terminal device.

[0273] The configuration information may include indication information; wherein, the indication information may be used to indicate that the state of the first measurement group is active, and the active state may be used to indicate that the first measurement group is measured.

[0274] In some embodiments, the configuration information may further include: an identifier for at least one measurement group, and an identifier for at least one reference signal and / or at least one cell identifier included in the measurement group.

[0275] In some embodiments, the configuration information may also include preset conditions corresponding to the measurement group.

[0276] It is understandable that in the case of multiple measurement groups, the first measurement group is included among the multiple measurement groups. Apart from the first measurement group, the other measurement groups in the multiple measurement groups can be in an inactive state. This inactive state can be used to indicate that the measurement group is not measured.

[0277] It should be noted that the specific contents of the measurement group identifier, reference signal identifier, cell identifier, and preset conditions in this step can be referred to the specific contents of the measurement group identifier, reference signal identifier, cell identifier, and preset conditions in step S301, and will not be repeated here.

[0278] S402. The terminal device performs measurements on the first measurement group according to the configuration information or in response to the fulfillment of the first preset condition.

[0279] The terminal device can perform measurements on the first measurement group according to the instructions in the configuration information.

[0280] It should be noted that the specific execution process of step S402 can be referred to the specific execution process of step S202, and will not be repeated here.

[0281] It should be noted that network devices can send configuration information to terminal devices multiple times. Newly sent configuration information can be used to modify, add to, or delete previously sent configuration information.

[0282] The measurement method provided in this disclosure allows network devices to carry indication information through configuration information, eliminating the need for network devices to send indication information to terminal devices. This reduces the number of interactions between network devices and terminal devices, saving resources. Terminal devices can perform measurements on the first measurement group based on the indication information or in response to meeting a first preset condition. Thus, when measuring the first measurement group, the terminal device does not need to receive different measurement configuration information, avoiding repeated measurements and reporting of at least one reference signal and / or at least one cell in the first measurement group based on different measurement configuration information. This reduces the measurement and reporting overhead of the terminal device and saves its resources.

[0283] Figure 5 is a schematic diagram of one of the structures of the measuring device provided in this embodiment. The measuring device 10 can be a terminal device, or a chip or chip module in the terminal device. Referring to Figure 5, the measuring device 10 may include:

[0284] Processing module 11 is used to measure a first measurement group according to an instruction or in response to a first preset condition, wherein the first measurement group includes at least one reference signal and / or at least one cell.

[0285] The indication information is used to instruct the first measurement group to be measured, and the first preset condition is the condition corresponding to the first measurement group.
