Description

Measurement method, device and computer readable storage medium

[0001] The present application claims priority to the Chinese patent application No. 202410873677.X, filed on July 01, 2024, and entitled "Measurement method, device and computer readable storage medium", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, in particular to a measurement method, device and computer readable storage medium. BACKGROUND

[0003] Beamforming is a signal processing technology based on an antenna array. By adjusting the weight and / or phase of the antenna array, beamforming can form a directional beam, which can concentrate signal energy in a certain direction for transmission, thereby improving beam gain, effectively improving coverage, reducing interference to the surrounding, and improving communication performance.

[0004] In a wireless communication system, an access network device can configure a layer 3 (L3) measurement for a terminal device. When performing a millimeter wave L3 measurement, the terminal device usually needs to improve the receiving gain through beamforming technology, and perform beam scanning on different receiving beams to measure the signal quality corresponding to different receiving beams. SUMMARY

[0005] Embodiments of the present application disclose a measurement method, device and computer readable storage medium, which can meet the related rapid measurement requirements of the terminal device while keeping the power consumption of the terminal device from being too high.

[0006] A first aspect discloses a measurement method, which can be applied to a terminal device, a component (e.g., a processor, a chip, a chip system, a circuit or a functional module) in the terminal device, and a logic module or software capable of realizing all or part of the functions of the terminal device. The terminal device can include multiple antenna panels. The measurement method is described below by taking the terminal device as an example. The measurement method can include: in a case where a trigger condition of a multi-antenna panel measurement is met, performing measurement on a measurement object corresponding to a first measurement object (MO) through multiple antenna panels in parallel.

[0007] In the embodiments of the present application, a triggering condition of multi-antenna panel measurement can be defined, and the terminal device can start multi-antenna panel measurement / beam scanning only when the triggering condition of multi-antenna panel is met. In this way, the scenario in which the terminal device uses multiple antenna panels for parallel measurement can be controlled, and the terminal device can be triggered to start / activate multiple antenna panels for parallel measurement only in a scenario with fast measurement requirements, such as a scenario with potential cell switching requirements, secondary carrier addition requirements, and the like, thereby avoiding unnecessary multi-antenna panel parallel measurement and saving power consumption.

[0008] In combination with the first aspect, in a possible implementation, the measurement object corresponding to the first MO is measured by a single antenna panel in a case where an exit condition of multi-antenna panel measurement is met.

[0009] In the embodiments of the present application, an exit condition of multi-antenna panel measurement can also be defined, and the terminal device can switch from parallel measurement by multiple antenna panels to measurement / beam scanning by a single antenna panel when the exit condition of multi-antenna panel is met. In this way, the terminal device can avoid using multiple antenna panels for parallel measurement all the time, and the terminal device can fall back to single-panel measurement when there is no fast measurement requirement, thereby saving the power consumption of the terminal device.

[0010] In combination with the first aspect, in a possible implementation, the triggering condition of multi-antenna panel measurement includes one or more of the following: the signal quality of the serving cell of the terminal device is less than a first threshold, the absolute value of the change of the signal quality of the serving cell of the terminal device within a first time period is greater than a second threshold, the time from the last time the terminal device exits multi-antenna panel measurement is greater than a third threshold, the measurement object corresponding to the first MO is configured for multi-antenna panel measurement, the terminal device triggers out-of-sync, and the terminal device triggers beam failure.

[0011] In the embodiments of the present application, the triggering condition of the multi-antenna panel measurement has high flexibility, and can be set according to actual conditions, so that the terminal device related rapid measurement requirement can be met while the power consumption of the terminal device is not too high. Further, the conditions that the signal quality of the serving cell of the terminal device is less than the first threshold, the absolute value of the change of the signal quality of the serving cell of the terminal device in the first time period is greater than the second threshold, the terminal device triggers out-of-sync, and the terminal device triggers beam failure, usually indicate that the terminal device can soon change the mobility state, such as cell switching, deleting the current SCell, adding a new SCell, and the like. Therefore, the requirement of rapid measurement is more urgent in these cases, and the related measurement results can be obtained more quickly by performing measurement in parallel through multiple panels in these cases, so that the access network device can perform related processing, ensure the service quality of the terminal device, and avoid the terminal device from being in a no-signal state.

[0012] In combination with the first aspect, in a possible implementation, the triggering condition of the multi-antenna panel measurement includes one or more triggering conditions, and the triggering condition of the multi-antenna panel measurement is met when any one of the one or more triggering conditions is met. Each of the one or more triggering conditions includes one or more of the following: the signal quality of the serving cell of the terminal device is less than the first threshold, the absolute value of the change of the signal quality of the serving cell of the terminal device in the first time period is greater than the second threshold, the time from the last time when the terminal device exits the multi-antenna panel measurement is greater than the third threshold, the measurement object corresponding to the first MO is configured as the multi-antenna panel measurement, the terminal device triggers out-of-sync, and the terminal device triggers beam failure.

[0013] In the embodiments of the present application, one or more triggering conditions can be configured for the terminal device according to actual conditions, and the flexibility is high. When any one of the one or more configured triggering conditions is met, the terminal device can perform measurement in parallel through multiple panels.

[0014] In combination with the first aspect, in a possible implementation, the third threshold is positively correlated with the signal quality of the serving cell of the terminal device.

[0015] In the embodiments of the present application, the third threshold value can be positively correlated with the signal quality of the serving cell of the terminal device, that is, the worse the signal quality of the serving cell of the terminal device, the smaller the third threshold value can be, and the better the signal quality of the serving cell of the terminal device, the larger the third threshold value can be. In this way, the terminal device can reduce the time length of falling back to single-panel measurement when the signal quality of the serving cell is poor, so as to obtain relevant measurement results as soon as possible, facilitate the network device to process (such as cell switching) according to the relevant measurement results, and also can increase the time length of falling back to single-panel measurement when the signal quality of the serving cell is good, so as to save power consumption.

[0016] In combination with the first aspect, in a possible implementation, the exit condition of the multi-antenna panel measurement includes one or more of the following: the signal quality of the serving cell of the terminal device is greater than a fourth threshold value, the terminal device reports at least one measurement report that the signal quality of the measurement object corresponding to the first MO is greater than a fifth threshold value, the terminal device reports at least one measurement report that the signal quality of the measurement object corresponding to the second MO is greater than a sixth threshold value, the terminal device has performed multi-antenna panel measurement on the measurement object corresponding to the first MO for a first time length, and the terminal device triggers the first event to report; wherein the measurement object corresponding to the first MO is different from the measurement object corresponding to the second MO, and the first event is an event of discovering that the signal quality of the neighbor cell is improved.

[0017] In the embodiments of the present application, the exit condition of the multi-antenna panel measurement has high flexibility, which can be set according to actual conditions, so that the terminal device can meet the related fast measurement requirements while ensuring that the power consumption of the terminal device is not too high. Further, the conditions that the signal quality of the serving cell of the terminal device is greater than the fourth threshold value, the terminal device reports at least one measurement report that the signal quality of the measurement object corresponding to the first MO is greater than the fifth threshold value, the terminal device reports at least one measurement report that the signal quality of the measurement object corresponding to the second MO is greater than the sixth threshold value, and the terminal device triggers the first event to report, usually indicate that the terminal device can not have mobility state changes in a short time or the access network device already has candidate cells for cell switching, SCell addition and other operations, so the urgency of fast measurement in these cases is low, and measurement can be performed through a single antenna panel in these cases to save power consumption.

[0018] In a possible implementation of the first aspect, the exit conditions of the multi-panel measurement include one or more exit conditions, and the exit conditions of the multi-panel measurement are met when any one of the one or more exit conditions is met. Each of the one or more exit conditions includes one or more of the following: a signal quality of a serving cell of the terminal device is greater than a fourth threshold, the terminal device reports a measurement report of a signal quality of a measurement object corresponding to the first MO being greater than a fifth threshold at least once, the terminal device reports a measurement report of a signal quality of a measurement object corresponding to the second MO being greater than a sixth threshold at least once, the terminal device performs the multi-panel measurement on the measurement object corresponding to the first MO for a first time length, and the terminal device triggers a first event. The measurement object corresponding to the first MO is different from the measurement object corresponding to the second MO, and the first event is an event of finding a neighbor cell with a better signal quality.

[0019] In the embodiments of the present application, one or more exit conditions can be configured for the terminal device according to actual conditions, and the flexibility is high. When any one of the one or more configured exit conditions is met, the terminal device can perform measurement through a single panel.

[0020] In a possible implementation of the first aspect, the terminal device performs the multi-panel measurement on the measurement object corresponding to the first MO for a first time length includes that the terminal device performs the multi-panel measurement on the measurement object corresponding to the first MO for a first time length and does not find a neighbor cell with a signal quality greater than a seventh threshold, or the terminal device performs the multi-panel measurement on the measurement object corresponding to the first MO for a first time length and finds a neighbor cell with a signal quality greater than an eighth threshold.

[0021] In the embodiments of the present application, the terminal device having performed the multi-antenna panel measurement on the measurement object corresponding to the first MO for the first time length can also be combined with other conditions, for example, whether a neighbor cell meeting a condition (for example, the signal quality is greater than a certain threshold) is found. For example, the terminal device having performed the multi-antenna panel measurement on the measurement object corresponding to the first MO for the first time length and not finding a neighbor cell with signal quality greater than the seventh threshold value can indicate that the terminal device has performed the multi-panel fast measurement for a long time but has not found a neighbor cell meeting the condition, and the probability of subsequently continuing to perform the multi-panel fast measurement on the measurement object corresponding to the first MO to find a neighbor cell meeting the condition is low. Therefore, the terminal device can not continue to perform the multi-panel fast measurement, otherwise the power consumption will be increased. For another example, the terminal device having performed the multi-antenna panel measurement on the measurement object corresponding to the first MO for the first time length can specifically mean that the terminal device has performed the multi-antenna panel measurement on the measurement object corresponding to the first MO for the first time length and has found a neighbor cell with signal quality greater than the eighth threshold value. This can indicate that the terminal device has found one or more neighbor cells meeting the condition through the multi-panel fast measurement within the first time length, and it can be considered that the access network device already has a candidate cell for cell switching, SCell addition and the like. The terminal device can switch to single-panel measurement.

[0023] In combination with the first aspect, in a possible implementation, the method further includes: receiving first configuration information from the network device, the first configuration information being used to determine the triggering condition of the multi-antenna panel measurement and / or the exit condition of the multi-antenna panel measurement.

[0024] In the embodiments of the present application, the access network device can flexibly configure the related parameters (for example, the first threshold value, the second threshold value and the like) of the triggering condition of the multi-antenna panel measurement and / or the exit condition of the multi-antenna panel measurement for the terminal device, so that the related parameters are more appropriate, that is, more in line with the actual scene, thereby making the power consumption utilization efficiency of the terminal device higher.

[0075] Embodiments of the present application disclose a measurement method, apparatus and computer readable storage medium, which can meet the related fast measurement requirements of a terminal device while not causing high power consumption of the terminal device. The technical solutions in embodiments of the present application will be clearly and completely described below with reference to the drawings.

[0076] In order to better understand the embodiments of the present application, the related contents, terms or names involved in the present application are briefly introduced as follows.

[0077] I. Beamforming

[0078] Beamforming is a signal processing technology based on an antenna array. Beamforming can form a directional beam by adjusting the weight and / or phase of the antenna array, can concentrate signal energy in a certain direction for transmission, thereby improving beam gain, effectively improving coverage, and reducing interference to the surrounding, and improving the performance of communication.

[0079] For example, for a 5G system, the working frequency bands include frequency range (FR) 1 and frequency range 2 (FR2). The frequency used in the FR2 frequency band is relatively high, such as a millimeter wave frequency band, and the transmission path loss is large, so it is usually necessary to implement coverage through beamforming technology. For example, cell coverage can be achieved by deploying multiple beams, that is, multiple transmission beams (Tx beams) are deployed to implement cell coverage.

[0080] II. Beam scanning

[0081] In the case of deploying multiple beams (multiple transmission beams) in a cell, the cell / access network device can send reference signals (RS) in different directions (or different transmission beams), such as sending synchronization signals and PBCH blocks (SSB) in different directions, where PBCH refers to a physical broadcast channel (PBCH). The user equipment (UE) can measure the SSB sent by the access network device to obtain the measurement result of each SBB, such as obtaining the reference signal received power (RSRP) of each SBB. Based on the RSRP of each SBB, the best transmission beam for the UE can be determined. At the same time, in some cases, the UE can include multiple receive beams (Rx beams) for the UE. In this case, for the SSB sent by the access network device through one transmission beam, the UE can receive the SSB sent by the access network device through different receive beams to determine the best receive beam for one transmission beam. That is, if the access network device includes n transmission beams and the UE includes m receive beams, then a total of n*m beam combinations (transmission beam and receive beam pairs) can be included. In actual cases, beam scanning can be performed to determine a beam combination with higher beam gain for communication.

[0082] For example, as shown in FIG. 1, it is assumed that the access network device includes 5 transmission beams (e.g., Tx1-Tx5) and the UE includes 5 reception beams (e.g., Rx1-Rx5). The access network device can respectively transmit SSB0-SSB4 through the 5 transmission beams (Tx1-Tx5), and the UE can respectively receive the SSB0-SSB4 transmitted by the access network device through the 5 reception beams, and can determine the beam combination with the highest beam gain, for example, if the RSRP of SSB1 received by the UE through Rx4 is the highest compared with other beam combinations, it can be determined that Tx2 and Rx4 can be the best beam combination. In some cases, the UE can report the beam measurement result to the access network device, and the access network device can determine the best transmission beam for the UE based on the beam measurement result, or the UE can directly report the best transmission beam.

[0083] In some possible embodiments, the access network device can indicate the beam information through a transmission configuration indicator (TCI). The TCI can indicate a quasi co-located (QCL) relationship, for example, the QCL can be divided into the following 4 types:

[0084] QCL Type A (QCL-Type A): {doppler shift, doppler spread, average delay, delay spread};

[0085] QCL Type B (QCL-Type B): {doppler shift, doppler spread};

[0086] QCL Type C (QCL-Type C): {doppler shift, average delay};

[0087] QCL Type D (QCL-Type D): {spatial Rx parameter}.

[0088] QCL-Type A~C is QCL information related to time / frequency synchronization processing, and QCL-Type D is QCL information related to beams. For example, in the case of conveying beam information, QCL-Type D can be used, and QCL-Type D can indicate that the beam information is inherited from the reference signal. For example, the access network device can schedule the UE to receive a physical downlink shared channel (PDSCH), and the TCI configuration of the PDSCH is QCL-type D to SSB1, then the UE uses the receive beam of receiving SSB1 to receive the PDSCH.

[0089] Three, antenna panel

[0090] In the embodiments of the present application, the UE can include multiple antenna panels. Among them, the beam of each antenna panel in the multiple antenna panels can be independently adjusted, but at the same time, a single antenna panel can only form a beam pointing to one direction. That is, each antenna panel can independently form a receiving beam to receive an air interface signal. In some possible implementation manners, the multiple antenna panels included by the UE can be installed at different positions of the UE, so as to reduce the signal correlation received by different antenna panels and improve the receiving performance. The antenna panel can also be referred to as a panel, an antenna array, an antenna subarray, an antenna array unit, an antenna array block, etc., and the embodiments of the present application are not limited thereto.

[0091] It should be understood that the antenna panel can include radio frequency components that form a beam. For example, the antenna panel can include an antenna array / antenna subarray / multiple antenna elements / multiple array elements, and related radio frequency components.

[0092] In some embodiments, the UE activating multiple antenna panels can be referred to as multi-panel or multi-Rx, etc., and the embodiments of the present application are not limited thereto.

[0093] Four, beam failure

[0094] The access network device can configure a UE with a beam failure detection resource group for beam failure detection (BFD) and a candidate beam resource group for determining candidate beams. When performing beam failure detection, the UE can determine that a beam failure occurs when it detects that the signal quality of a resource (e.g., a serving beam) in the beam failure detection resource group is below a certain threshold. For example, when the physical layer detects that the measurement value of a reference signal in the serving beam satisfies a certain threshold (e.g., the BLER of the physical downlink control channel (PDCCH) exceeds 10%), a beam failure instance indication (BFI) can be triggered and sent to the MAC layer. After receiving the beam failure instance indication, the MAC layer can start a timer and can increment a counter by one each time a BFI is received. When the counter is greater than or equal to a beam failure maximum value (e.g., beamFailureInstanceMaxCount) before the timer expires, the MAC layer can trigger a beam failure. After a beam failure occurs, the UE can perform candidate beam detection (CBD) measurements on the resources in the candidate beam resource group to select a beam corresponding to a resource with better signal quality from the candidate beam resource group based on the candidate beam measurement results for beam failure recovery.

[0095] It should be understood that the above description of beam failure is only exemplary, and more detailed descriptions of beam failure can be found in the relevant descriptions in the standards.

[0096] Five, radio link monitoring (RLM)

[0097] RLM generally refers to a process in which a UE measures a relevant reference signal (e.g., an SSB or a channel state information reference signal (CSI-RS)) to monitor the downlink communication quality of a serving cell. RLM is mainly applied to PCell, PSCell, and other scenarios, and can measure the reference signal of a PCell, PSCell, or other cell to monitor the communication quality of the PCell, PSCell, or other cell.

[0098] For example, the UE can perform periodic L1 measurement according to an L1 measurement period to evaluate the radio link quality of the serving cell. When the UE determines, through the evaluation, that the radio link quality is lower than a corresponding threshold, the UE can trigger out-of-sync, in which case the L1 of the UE can trigger an out-of-sync signal to the layer 3 (L3) of the UE, i.e., the L1 of the UE can report the out-of-sync to the L3 of the UE. When the UE determines, through the evaluation, that the radio link quality is higher than a corresponding threshold, the UE can trigger in-of-sync, in which case the L1 of the UE can trigger an in-of-sync signal to the L3 of the UE, i.e., the L1 of the UE can report the in-of-sync to the L3 of the UE.

[0099] It should be understood that the above description of the related description of the radio link monitoring is only exemplary, and more detailed description of the radio link monitoring can be referred to the related description in the standard.

[0100] Six, L1 measurement and L3 measurement

[0101] Layer 1 (L1) can refer to a physical layer (PHY), and correspondingly, the L1 measurement can also be a physical layer measurement. For example, the UE can measure the reference signal of the serving cell based on the related configuration of the L1 measurement, and report the measurement result, such as RSRP, signal-to-interference plus noise ratio (SINR), etc., to the access network device. The access network device can perform beam management, etc., based on the L1 measurement result.

[0102] Layer 3 (L3) can refer to a radio resource control (RRC) layer, and correspondingly, the L3 measurement can also be an RRC layer measurement. The L3 measurement is mainly used for mobility management, which can also be referred to as mobility measurement. For example, from the perspective of the type of measured reference signal, the L3 measurement can be divided into SSB-based L3 measurement, CSI-RS-based L3 measurement, etc. From the perspective of the frequency point of the measured reference signal, the L3 measurement can be divided into intra-frequency measurement, inter-frequency measurement, etc.

[0103] The indicators measured by L3 measurement can be RSRP, reference signal received quality (RSRQ), signal-to-interference plus noise ratio (SINR), etc., and the embodiments of the present application do not limit this.

[0104] Generally, the access network device can configure one or more measurement objects (MOs) for the UE. Taking L3 measurement as SSB-based measurement as an example, the MO can include information of a target frequency point, SSB-based measurement timing configuration (SMTC), etc. Based on SMTC, the UE can search and measure SSBs on the target frequency point within the corresponding time.

[0105] For example, the access network device can send a plurality of SSBs (such as 4, 8, 16, etc.) in a fixed period (such as 5, 10, 20, 40, 80, 160 milliseconds (ms), etc.), and the plurality of SSBs can also be referred to as an SSB block / SSB burst set, and the plurality of SSBs can be sent through different transmission beams. The SMTC can configure an SMTC occasion, which is the duration of a measurement window, and a plurality of SSBs of a cell (such as a neighbor cell) on the target frequency point can be transmitted within the measurement window, and accordingly, the UE can measure the SSBs within the measurement window configured by the SMTC. It should be understood that the SMTC occasion can occur periodically, for example, the SMTC can configure the period of the SMTC occasion as 20 milliseconds (ms) and the duration as 5 ms, in this case, the UE can measure the SSBs of the cell (such as a neighbor cell) on the target frequency point for a duration of 5 ms in every 20 ms.

[0106] After the UE measures the frequency point indicated by the MO configured by the access network device and obtains the measurement result of the cell (such as a neighbor cell) on the frequency point, the UE can report the measurement result to the access network device, and the access network device can perform component carrier addition / deletion, cell switching, etc. based on the measurement result reported by the UE to ensure that the UE obtains better service quality.

[0107] The reporting mode of the measurement result includes periodic reporting and event reporting, which can be configured by the access network device, such as through reportconfig. Among them, the periodic reporting is that the UE periodically reports the measurement result according to a certain period, such as periodically reporting the measurement result according to the reporting period configured by the access network device. The event reporting is that the UE reports when the corresponding event occurs / triggered, and the event that the UE needs to report can be configured by the access network device, such as configured by the access network device through RRC signaling / message. For example, the following events can be defined:

[0108] Event A1 (eventA1): the signal quality of a serving cell (SC) is higher than an absolute threshold;

[0109] Event A2 (eventA2): the signal quality of the serving cell is lower than an absolute threshold;

[0110] Event A3 (eventA3): the signal quality of a neighbor cell is higher than the signal quality of a primary cell (PCell) / primary secondary cell (PSCell) by an offset;

[0111] Event A4 (eventA4): the signal quality of the neighbor cell is higher than an absolute threshold;

[0112] Event A5 (eventA5): the signal quality of the PCell / PSCell is lower than an absolute threshold (such as threshold 1) and the signal quality of a neighbor cell / secondary cell (SCell) is higher than an absolute threshold (such as threshold 2);

[0113] Event A6 (eventA6): the signal quality of the neighbor cell is higher than the signal quality of the SCell by an offset.

[0114] The above-mentioned serving cell can be a cell that provides service (communication service) for the UE, and the serving cell can be a PCell, a PSCell, or an SCell.

[0115] Exemplarily, the measurement object (MO) and the report configuration configured by the access network device can be associated by a measurement identifier (MeasID). For example, one MeasID can be assigned by the access network device for one measurement object and the report configuration. Assuming that the report configuration is A4 and the MO indicates one FR2 frequency point, when a neighbor better than an absolute threshold is found at the FR2 frequency point, the measurement result reporting is triggered. It should be understood that the above description of the related L3 measurement is only exemplary, and more detailed description of the L3 measurement can be referred to the description in the related standards.

[0116] When the UE performs measurement (such as L3 measurement), it needs to perform beam scanning on different directions (or different beams) through beamforming. Generally, when performing measurement, the UE can activate one antenna panel, that is, at one time, the UE can form a beam pointing to one direction, that is, it can support one receiving beam direction, so the UE can scan one beam (or receiving beam) in one direction in one SMTC period. Exemplarily, as shown in FIG. 2, assuming that the UE needs to perform beam scanning on 8 directions through beamforming, the UE needs 8 SMTC periods to complete one round of measurement, and one beam in one direction can be measured in each SMTC period. And in some cases, for one SSB (such as SSB1, SSB2, etc.), the UE needs multiple SSB samples to complete one measurement, such as taking the average of 5 SSB measurements. Taking 5 SSB samples as an example, a total of 5*8 SMTC periods are needed. Assuming that the SMTC period is 20 ms, a total of 800 ms is needed.

[0117] Currently, the use of multi-antenna panel features is mainly used to improve the throughput of the serving cell / UE, and the UE can turn on / activate multiple antenna panels to simultaneously receive data in multiple directions. There is no clear technical discussion or conclusion in the industry on how to accelerate measurement (such as L3 measurement) through multiple antenna panels, and the opening and closing conditions of multi-panel fast L3 measurement.

[0118] For example, in order to improve the measurement speed / beam scanning speed, multiple antenna panels can be configured for the UE, and the UE can perform measurement on multiple beam directions simultaneously through the multiple antenna panels. As shown in FIG. 3, it is assumed that the UE includes two antenna panels, and measurement on two beam directions can be performed simultaneously, in which case two beam directions can be measured in each SMTC period, and thus four SMTC periods can complete one round of measurement, and eight beam directions can be measured. If the UE needs to perform five SSB samples for one measurement, a total of five*4 SMTC periods are needed. Assuming that the SMTC period is 20 ms, a total of 400 ms is needed, and thus compared with the measurement process shown in FIG. 2, the time can be reduced by half.

[0119] It can be understood that although the UE opens multiple antenna panels to accelerate the measurement speed / beam scanning speed, the power consumption is also increased. Therefore, how to meet the requirement of fast measurement and reduce the power consumption is a problem that the related technicians are concerned about.

[0120] In the embodiments of the present application, in order to meet the requirement of fast measurement and balance the power consumption, the triggering condition and the exit condition of the multi-antenna panel measurement are defined, the UE can open the multi-antenna panel to perform measurement / beam scanning when the triggering condition of the multi-antenna panel is met, and the UE can open the single-antenna panel to perform measurement / beam scanning when the exit condition of the multi-antenna panel is met. In this way, the UE can perform measurement / beam scanning through the multi-antenna panel in a scenario requiring fast measurement, such as performing measurement / beam scanning through the multi-antenna panel in a scenario requiring handover based on the measurement result, so as to meet the related requirements (such as handover requirement, SCell addition requirement, etc.) as soon as possible. In this way, the UE can also perform measurement through the single-antenna panel in a scenario not requiring fast measurement, so as to reduce the overall power consumption of the UE.

[0121] In order to better understand the embodiments of the present application, the system architecture and the related information model of the embodiments of the present application will be described first.

[0122] Please refer to FIG. 4, which is a schematic diagram of a communication system provided by the embodiments of the present application. As shown in FIG. 4, the communication system can include one or more user equipment (one is shown in FIG. 4) and one or more access network devices (one is shown in FIG. 4). The user equipment and the access network device can communicate with each other, and the user equipment and the access network device will be introduced respectively.

[0123] The user equipment (UE), also known as terminal device, terminal, mobile station (MS), mobile terminal (MT), customer premise equipment (CPE), etc., is a device with wireless communication function, which can provide voice and / or data connectivity services for users. The terminal device can be a handheld terminal, a notebook computer, a road side unit (RSU), a subscriber unit, a cellular phone, a smart phone, a wireless data card, a personal digital assistant (PDA) computer, a tablet computer, a tag, a wireless modem, other processing devices connected to the wireless modem, a handheld device, a laptop computer, a cordless phone, or a wireless local loop (WLL) station, a machine type communication (MTC) terminal, a wearable device (such as a smart watch, a smart bracelet, a pedometer, etc.), a vehicle-mounted device (such as a car, a bicycle, an electric vehicle, an airplane, a ship, a train, a high-speed rail, etc.), a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a smart home device (such as a refrigerator, a television, an air conditioner, an electric meter, etc.), a smart robot, a workshop device, a wireless terminal in self driving, a wireless terminal in remote medical surgery, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, or a wireless terminal in smart home, a flight device (such as a smart robot, a hot air balloon, a drone, an airplane, etc.) or other devices that can access a network. The terminal device can be fixed or mobile, and can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; can also be deployed on the water surface (such as a ship, etc.); and can also be deployed in the air (such as an airplane, a balloon and a satellite, etc.).

[0124] In an embodiment of the present application, the terminal device can include multiple antenna panels, such as 2, 3 or more. Each of the multiple antenna panels included by the terminal device can be independently controlled, that is, the amplitude and / or phase and the like can be independently adjusted, so that the terminal device can form beams in different directions, so that the terminal device can send or receive signals in different directions.

[0125] The access network device can be a device that provides access / communication services for the terminal device, and can include a radio access network (RAN) device and an access node (AN) device. The RAN device can include various forms of base stations, such as macro base stations, micro base stations (also referred to as small stations), relay stations, access points, balloon stations, and the like. In systems that employ different wireless access technologies, the name of the radio access network device can be different. For example, the evolved NodeB (eNB or eNodeB) in long term evolution (LTE), the next generation NodeB (gNB) in the 5th generation (5G) mobile communication system, the ng-eNB (4G base station accessing the 5G core network). The radio access network device can also be a radio controller in a cloud radio access network (CRAN) scenario, a base station device in a future network (such as 6G, 7G, etc.), a radio access network device in a future evolved public land mobile network (PLMN) network, a wearable device, a vehicle-mounted device, a transmission and reception point (TRP), a radio network controller (RNC), a home base station (such as a home evolved NodeB, or a home NodeB, HNB), a baseband unit (BBU), an access node (AP) in a wireless fidelity (WiFi) system, and the like.

[0126] In some deployments, an access network device (e.g., gNB) can include a centralized unit (CU) and a distributed unit (DU), etc. The access network device can also include a radio unit (RU), which can be specifically referred to as FIG. 5. As shown in FIG. 5, the access network device can communicate with a core network (CN) through a backhaul, and communicate with a terminal device (UE) through an air interface (e.g., Uu interface). Specifically, a baseband unit (BBU) in the access network device can communicate with the core network through the backhaul, and a radio unit in the access network device can communicate with the terminal device through the air interface. Moreover, the BBU can communicate with the RU through a front-haul, and the BBU and the RU can be co-located or not. The BBU can include at least one centralized unit (CU) and at least one distributed unit (DU), and the CU and the DU can communicate through a mid-haul. For example, the CU can be connected with the DU through an F1 interface, and the interface between the DU and the RU can be a common public radio interface (CPRI) or an enhanced common public radio interface (eCPRI). Among them, the CU can implement part of the functions of the access network device, the DU can implement part of the functions of the access network device, and the CU can be used to control the operation of one or more DUs. For example, the CU can implement the functions of the radio resource control (RRC) and the packet data convergence protocol (PDCP) layer, and can also implement the function of the service data adaptation protocol (SDAP) layer, the DU can implement the functions of the radio link control (RLC) and the media access control (MAC) layer, and can also implement part of the physical (PHY) layer (such as the higher physical (Higher PHY) layer) or all the physical layer functions, and the RU can be used to implement part of the physical layer functions (such as the lower physical (Lower PHY) layer) and radio frequency functions. For specific descriptions of the above protocol layers, please refer to the relevant technical specifications of the 3rd generation partnership project (3GPP).It can be understood that, in some possible implementation, the access network device can be a CU node or a DU node or a device including a CU node and a DU node.

[0127] An architecture of an open wireless access network is introduced below.

[0128] Please refer to FIG. 6, which is a schematic diagram of an architecture of an open wireless access network disclosed in an embodiment of the present application. As shown in FIG. 6, the open wireless access network (open RAN, O-RAN) introduces a RAN intelligent controller (RIC), which can realize intelligent management, operation and maintenance, etc. The RIC can include a near-real time RIC (near-RT RIC) and a non-real time RIC (Non-RT RIC).

[0129] The near-real time RIC refers to a near-real time part, which is mainly responsible for processing services with less delay requirement, such as services less than 1 second (50ms-200ms), for example, wireless resource management, handover decision, connection control, load balancing, etc. Illustratively, the near-real time RIC can obtain information (such as network side information, terminal side information, etc.) from a RAN node (such as a CU, a CU-CP (control plane), a CU-UP (user plane), a DU, a RU, a SU, etc.), a terminal device, a non-real time RIC and other devices, and then can perform artificial intelligence (AI) model training based on the obtained information, or can input the obtained information into a trained AI model to obtain an inference result, which can be a network parameter, such as a RAN parameter (priority parameter, handover parameter), etc. Optionally, the near-real time RIC can send the inference result to the RAN node and / or the terminal device. Optionally, the inference result can be interacted between the CU and the DU, between the DU and the RU, etc. For example, the near-real time RIC can send the inference result to the DU, and the DU can send the inference result to the RU.

[0130] The non-real-time RIC refers to a non-real-time part, which is mainly responsible for processing services with relatively large latency requirements, such as services greater than 1 second, such as data analysis, AI model training, and the like. For example, the non-real-time RIC can obtain information (such as network side information, terminal side information, and the like) from a RAN node (such as a CU, a CU-CP, a CU-UP, a DU, a RU, a SU, and the like), a terminal device, a near-real-time RIC, and other devices, and then can perform AI model training based on the obtained information, or can input the obtained information into a trained AI model to obtain an inference result. The inference result can be a network parameter, such as a RAN parameter (a priority parameter, a handover parameter), and the like. The non-real-time RIC can send the inference result to the RAN node and / or the terminal. Alternatively, the non-real-time RIC can send the inference result to the RAN node, the terminal, the near-real-time RIC, and the like. Alternatively, the CU and the DU, the DU and the RU, and the like can interact with the inference result. For example, the non-real-time RIC can submit the inference result to the DU, which sends it to the RU.

[0131] In a possible implementation, the near-real-time RIC and the non-real-time RIC can be respectively set as a network element alone. In another possible implementation, the near-real-time RIC and the non-real-time RIC can also be part of other devices, for example, the near-real-time RIC can be set in a RAN node (such as a CU, a DU, a SU), and the non-real-time RIC can be set in an operation administration and maintenance (OAM), a cloud server, a core network device, or other network devices. For more details about the open radio access network (O-RAN), such as interfaces, refer to the description in the related standards, which will not be described here.

[0132] Please refer to FIG. 7, which is a network element function division and protocol layer structure diagram of an O-RAN device disclosed in an embodiment of the present application. The following will be described in combination with FIG. 7.

[0133] In some examples, the CU can be a logical node that carries radio resource control (RRC) layer, service data adaptation protocol (SDAP) layer, packet data convergence protocol (PDCP) layer, and other control functions of the access network device. The CU can be connected with network nodes such as core network through some interfaces, which can be E2 interface or the like. Optionally, the CU can have part of the functions of the core network. The CU (such as PDCP layer and higher layer) is connected with the DU (such as RLC layer and lower layer) through some interfaces, which can be F1 interface or the like. In some examples, these interfaces (such as F1 interface) can provide control plane (C-Plane / CP) and user plane (U-Plane / UP) functions (for example, interface management, system information management, UE context management, RRC message transmission, and the like). F1AP (application protocol) is the application protocol of F1 interface, which defines the signaling process of F1 in some examples. The F1 interface supports control plane F1-C and user plane F1-U.

[0134] In some examples, the CU can be split into a CU-CP and a CU-UP. The CU-CP can be a logical node carrying the RRC layer and the PDCP-C (control plane part of PDCP) layer, and is used to implement the control plane function of the CU. The CU-CP can interact with a network element in the core network for implementing the control plane function. For example, the network element in the 5G core network for implementing the control plane function can be an access and mobility management function (AMF). The AMF network element can be responsible for mobility management in the mobile network, such as location updating of the terminal device, registration of the terminal device to the network, handover of the terminal device, and the like. The CU-UP can be a logical node carrying the SDAP layer and the PDCP-U (user plane part of PDCP) layer, and is used to implement the user plane function of the CU. The CU-UP can interact with a network element in the core network for implementing the user plane function. For example, the network element in the 5G core network for implementing the user plane function can be a user plane function (UPF). The UPF network element can be responsible for forwarding and receiving data of the terminal device. It should be understood that the above configuration of the CU and the DU is only an example, and the CU and the DU can be configured to have other functions according to needs. For example, the CU or the DU can be configured to have more protocol layer functions, or the CU or the DU can be configured to have partial processing functions of the protocol layers. For example, part of the functions of the RLC layer and the functions of the protocol layers above the RLC layer can be arranged in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer can be arranged in the DU. For another example, the functions of the CU or the DU can be divided according to the service type or other system requirements. For example, according to the delay requirement, the functions that need to meet the delay requirement can be arranged in the DU, and the functions that do not need to meet the delay requirement can be arranged in the CU. In the embodiments of the present application, the CU can also be referred to as an O-CU (O-RAN CU), the CU-CP can also be referred to as an O-CU-CP, and the CU-UP can also be referred to as an O-CU-UP.

[0135] In some examples, a DU can be a logical node that hosts a radio link control (RLC) layer, a media access control (MAC) layer, part of a physical layer function (e.g., a higher physical (Higher PHY) layer), and other functions. In some examples, a DU can control at least one RU. The DU is connected to the RU(s) through some interfaces, which can be a front-haul interface. It should be understood that the higher physical layer can include part of the physical layer processing, e.g., the higher physical layer function can include one or more of: forward error correction (FEC) encoding / decoding, scrambling / descrambling, or modulation / demodulation. In embodiments of the present application, the DU can also be referred to as an O-DU (O-RAN DU).

[0136] In some examples, an RU can be a logical node that hosts part of a physical layer function (e.g., a lower physical (Lower PHY) layer) and radio frequency (RF) processing. In some examples, an RU can be a transmission reception point (TRP) or a remote radio head (RRH) or other similar functional entity. In some examples, the lower physical layer can include part of the physical layer processing, e.g., the lower physical layer function can include one or more of: fast fourier transform (FFT) transform, inverse fast fourier transformation (IFFT) transform, digital beamforming, extraction and filtering of a physical random access channel (PRACH), etc. It should be understood that the RU can communicate with one or more UEs through a wireless link (e.g., an air interface). In embodiments of the present application, the RU can also be referred to as an O-RU (O-RAN RU).

[0137] It should be noted that the DU and the RU can be co-located or not co-located. The DU and the RU can exchange control-plane information and user-plane information via a lower-layer split control user synchronization (LLS-CUS) interface over a fronthaul link. The LLS-CUS can include an LLS-C interface providing a control-plane and an LLS-U interface providing a user-plane. In some examples, the control-plane refers to real-time control between the DU and the RU. The LLS-CUS can further include an LLS-M interface of the fronthaul link, and the DU and the RU can exchange management information over the LLS-M interface. The management-plane refers to non-real-time management operation between the DU and the RU.

[0138] It can be understood that the DU and the RU can cooperate to jointly implement the functions of the PHY layer. One DU can be connected to one or more RUs. The functions of the DU and the RU can be configured in multiple ways according to design. For example, the DU is configured to implement baseband functions, and the RU is configured to implement intermediate radio frequency functions. For another example, the DU is configured to implement high-layer functions in the PHY layer, and the RU is configured to implement low-layer functions in the PHY layer or implement the low-layer functions and radio frequency functions. The high-layer functions in the PHY layer can include a part of functions of the PHY layer closer to the MAC layer, and the low-layer functions in the PHY layer can include another part of functions of the PHY layer closer to the intermediate radio frequency side.

[0139] In some embodiments, one or more AI modules can also be arranged in the above-mentioned network element nodes. For example, one or more AI modules can be arranged in the core network device, the RAN node (such as the CU, the DU, the RU, etc.), and the terminal device, to perform related processing based on the AI module. For example, the CU, the DU, the RU, and the terminal device can perform wireless-related data analysis and policy feedback based on the AI module (for example, the DU can perform resource allocation based on the AI module). The AI module in the above-mentioned network element nodes can be issued by a near-real-time RIC, a non-real-time RIC, or the like, or can be trained by the relevant network element nodes themselves.

[0140] It should be noted that although the L3 measurement scenario is mainly taken as an example for description in the embodiments of the present application, the embodiments of the present application are not limited to the measurement scenario, and the embodiments of the present application can be applied to all beam scanning scenarios. It should be further noted that the architecture shown in FIGS. 4-7 is only illustrative, and other devices / network elements can also be included in the architecture shown in FIGS. 4-7, which is not limited in the embodiments of the present application.

[0141] It can be understood that the above-mentioned access network device, terminal device and the like can be realized in the form of hardware, computer software or a combination of hardware and computer software. Illustratively, the above-mentioned access network device, terminal device and the like can be realized by one device, can also be realized by multiple devices together, and can also be realized by one functional module in one device, and the present application embodiment does not make specific limitation thereto.

[0144] In order to better understand the embodiments of the present application, the overall concept of the embodiments of the present application will be exemplarily described below.

[0145] From the above description, it can be seen that if the terminal device opens / activates multiple panels for parallel measurement, the measurement speed can be improved, but at the same time, the power consumption will also increase. Based on this, the embodiments of the present application can use a combination of multi-antenna panel measurement and single-antenna panel measurement, that is, a way of alternating multi-antenna panel measurement and single-antenna panel measurement, so as to meet the related fast measurement requirements while keeping the power consumption of the terminal device not too high. That is, compared with the traditional single-panel measurement, this way can increase a small amount of additional power consumption to improve other aspects of performance, such as improving the switching efficiency, auxiliary carrier addition / deletion efficiency, etc., so as to guarantee the service quality of the terminal device. It should be noted that in the embodiments of the present application, the way of opening / activating multiple panels for parallel measurement by the terminal device can be referred to as multi-antenna panel measurement, multi-panel measurement, multi-panel fast measurement, fast measurement, multi-panel fast L3 measurement, etc., and the present application embodiment does not make limitation thereto.

[0146] Further, the embodiment of the present application defines a triggering condition of multi-antenna panel measurement and / or an exiting condition of multi-antenna panel measurement, so that the terminal device can start / activate multi-panel parallel measurement in a scenario / case where there is a fast measurement requirement, such as a scenario / case where there is a potential handover requirement or a scenario / case where there is a requirement of SCell addition, and can start / activate single-panel measurement in a scenario / case where there is no fast measurement requirement.

[0147] The overall flow of the technical solution provided by the embodiment of the present application is described below. In order to facilitate understanding of the embodiment of the present application, the triggering condition of multi-antenna panel measurement and the process of triggering the terminal device to perform fast measurement by multi-antenna panel are introduced in Embodiment One, and the exiting condition of multi-antenna panel measurement and the process of triggering the terminal device to exit fast measurement by multi-antenna panel are introduced in Embodiment Two.

[0148]

Embodiment One

[0149] Embodiment One is a related processing flow of the triggering condition of multi-antenna panel measurement and the process of triggering the terminal device to perform fast measurement by multi-antenna panel. In Embodiment One, the network device can configure the triggering condition of multi-antenna panel measurement for the terminal device, and then the terminal device can monitor whether the triggering condition of multi-antenna panel measurement is met, and in the case where the triggering condition of multi-antenna panel measurement is met, the terminal device needs to perform measurement by multiple antenna panels in parallel. Specifically, please refer to FIG. 8, which is a flowchart of a measurement method disclosed by the embodiment of the present application. As shown in FIG. 8, the method can include but is not limited to the following steps:

[0150] 801. The network device determines first configuration information, and the first configuration information is used to determine the triggering condition of multi-antenna panel measurement.

[0151] In order to facilitate understanding of the first configuration information, the triggering condition of multi-antenna panel measurement is described below. The triggering condition of multi-antenna panel can be understood as a condition of triggering the terminal device to start / activate multi-antenna panel to perform parallel measurement.

[0152] In the embodiments of the present application, the triggering (or entering) condition of the multi-antenna panel measurement can include one or more of the following: the signal quality of the serving cell of the terminal device is less than a first threshold, the absolute value of the change of the signal quality of the serving cell of the terminal device in a first time period is greater than a second threshold, the time from the last time the terminal device exits the multi-antenna panel measurement is greater than a third threshold, the measurement object corresponding to the first measurement object (MO) is configured as the multi-antenna panel measurement, the terminal device triggers out-of-sync, and the terminal device triggers beam failure. That is, the above-mentioned items can be used as a triggering condition for triggering the multi-antenna panel measurement, either individually or in combination.

[0153] In some possible implementation manners, the triggering condition of the multi-antenna panel measurement can include one or more triggering conditions, and the terminal device can be triggered to perform the multi-antenna panel measurement when any one of the one or more triggering conditions is met. Each triggering condition can include one or more of the following: the signal quality of the serving cell of the terminal device is less than a first threshold, the absolute value of the change of the signal quality of the serving cell of the terminal device in a first time period is greater than a second threshold, the time from the last time the terminal device exits the multi-antenna panel measurement is greater than a third threshold, the measurement object corresponding to the first measurement object (MO) is configured as the multi-antenna panel measurement, the terminal device triggers out-of-sync, and the terminal device triggers beam failure.

[0154] As can be seen from the above description of the triggering condition of the multi-antenna panel measurement, the triggering condition of the multi-antenna panel measurement has high flexibility. In some possible implementation manners, the network device can send relevant configuration information / assistance information (such as first configuration information) to the terminal device to facilitate the terminal device to determine the triggering condition of the multi-antenna panel measurement. For example, the network device can determine (or generate) the first configuration information, and the first configuration information can be used to determine the triggering condition of the multi-antenna panel measurement. For example, the first configuration information can include parameters used to determine the triggering condition of the multi-antenna panel measurement.

[0155] In some possible implementation manners, the first configuration information can include one or more of the following: a measurement target for which multi-panel measurement is performed, a frequency point for which multi-panel measurement is performed, a cell for which multi-panel measurement is performed, an event (such as an A2 event) for which multi-panel measurement is performed, threshold information related to a triggering condition, and the like. The threshold information can include the first threshold, the second threshold, the third threshold, the first time period, and the like. It should be understood that the measurement target for which multi-panel measurement is performed can be understood as a measurement target for which multi-panel measurement needs to be / is supposed to be performed, such as a measurement target for which multi-panel measurement needs to be / is supposed to be performed by the terminal device. Similarly, the frequency point for which multi-panel measurement is performed can be understood as a frequency point for which multi-panel measurement needs to be / is supposed to be performed, the cell for which multi-panel measurement is performed can be understood as a cell for which multi-panel measurement needs to be / is supposed to be performed, and the event for which multi-panel measurement is performed can be understood as an event for which multi-panel measurement needs to be / is supposed to be performed.

[0156] For example, the frequency point (such as a frequency point index) for which multi-panel measurement is performed can be one or more. For example, the network device can determine which frequency points are more important for the mobility of the terminal device, such as determining which frequency points are more important for the mobility of the terminal device according to the deployment of the frequency points / cells, so that the network device can configure these frequency points as frequency points for which multi-panel measurement needs to be performed. The cell (such as a cell ID) for which multi-panel measurement is performed can be one or more. For example, the network device can determine which cells are more important for the mobility of the terminal device, such as determining which neighboring cells are more important for the mobility of the terminal device according to the location of the cell in which the terminal device is currently located, so that the network device can configure these cells as cells for which multi-panel measurement needs to be performed. The measurement target (such as a MeasID) for which multi-panel measurement is performed can be one or more. For example, the network device can determine which measurement targets are more important for the mobility of the terminal device, so that the network device can configure these measurement targets as measurement targets for which multi-panel measurement needs to be performed. In a possible implementation manner, the network device can determine which measurement targets correspond to frequency points or cells that are more important for the mobility of the terminal device, and can configure these measurement targets as measurement targets for which multi-panel measurement needs to be performed.

[0157] It should be noted that the first threshold, the second threshold, the third threshold, the first time period, etc. described above can be fixed values or variable values. For example, the network device can dynamically adjust the above-mentioned thresholds according to actual conditions. For example, the network device can dynamically adjust the above-mentioned thresholds according to the signal quality of the serving cell of the terminal device. For example, the third threshold can be positively correlated with the signal quality of the serving cell of the terminal device. That is, the worse the signal quality of the serving cell of the terminal device, the smaller the third threshold can be, and the better the signal quality of the serving cell of the terminal device, the larger the third threshold can be. For example, when the RSRP value of the serving cell (such as a PCell) of the terminal device is greater than a threshold 1, the third threshold can be 20 seconds, when the RSRP value of the serving cell of the terminal device is less than or equal to the threshold 1 and greater than a threshold 2, the third threshold can be 10 seconds, and when the RSRP value of the serving cell of the terminal device is less than or equal to the threshold 2 and greater than a threshold 3, the third threshold can be 5 seconds. In this case, the third threshold included in the first configuration information can be a threshold list, and the threshold list can include the values of the third threshold under different signal qualities of the serving cell of the terminal device.

[0158] In the embodiments of the present application, the terminal device can also report capability information to the network device, and the capability information can include related information of the antenna panel of the terminal device, such as the number of antenna panels included in the terminal device, and the frequency band, frequency point, cell, etc. supported by each antenna panel, that is, the frequency band, frequency point, cell, etc. supported by the terminal device for multi-antenna panel measurement. Correspondingly, the network device can determine the first configuration information for the terminal device based on the capability information of the terminal device.

[0159] It should be understood that the network device can be an access network device or other device, and the embodiments of the present application do not limit this.

[0160] 802. The network device sends the first configuration information to the terminal device.

[0161] After determining the first configuration information, the network device can send the first configuration information to the terminal device. Correspondingly, the terminal device can receive the first configuration information from the network device.

[0162] It can be understood that the network device can send the first configuration information to the terminal device in various ways, and the embodiments of the present application do not limit this. For example, the first configuration information can be carried in certain downlink control signaling / messages (such as RRC signaling / messages), such as in RRC signaling / messages. For example, assuming that a certain downlink control signaling / message can include a field 1, a field 2 and a field 3, the field 1 can be a specific first threshold, the field 2 can be a specific second threshold, and the field 3 can be a specific third threshold.

[0163] It should be noted that in the embodiments of the present application, the network device can configure the triggering condition of the multi-panel measurement in different granularity. For example, the network device can configure the triggering condition of the multi-panel measurement in the granularity of the terminal device, so that each terminal device can have a corresponding triggering condition of the multi-panel measurement, which can be applicable to all measurements of the corresponding terminal device, or can be applicable to all L3 measurements of the corresponding terminal device, etc. For another example, the network device can configure the triggering condition of the multi-panel measurement in the granularity of the MO, so that each MO can have a corresponding triggering condition of the multi-panel measurement, and the first configuration information can be used to determine the triggering condition of the multi-panel measurement corresponding to the first processing target. For another example, the network device can configure the triggering condition of the multi-panel measurement in the granularity of the cell, frequency point, frequency band, etc., which is not limited in the embodiments of the present application.

[0164] For example, in the case where the network device configures the triggering condition of the multi-panel measurement in the granularity of the MO, the first configuration information can be associated with the corresponding MO, such as being associated with the first MO. In this case, when the network device sends the first configuration information to the terminal device, the network device can carry the identification information of the first MO, such as the measurement identification (MeasID) corresponding to the first MO, to indicate that the first configuration information can be used to determine the triggering condition of the multi-panel measurement corresponding to the first MO.

[0165] It can be understood that the steps 801 and 802 are optional. For example, in some possible implementation, the triggering condition of the multi-panel measurement can be predefined, such as being specified by the protocol, including specifying specific thresholds (such as the first threshold, the second threshold, the third threshold, etc.) and the like. For another example, in some possible implementation, the triggering condition of the multi-panel measurement can be specified by the protocol, but the network device can dynamically configure the related parameters (such as the first threshold, the second threshold, the third threshold, etc.). For example, the protocol can specify that the triggering condition of the multi-panel measurement is that the signal quality of the serving cell of the terminal device is less than a certain threshold, but the specific threshold can be configured by the network device. For another example, in some possible implementation, the triggering condition of the multi-panel measurement can be specified by the protocol, and the protocol can specify the default threshold, but the network device can dynamically configure the related parameters (such as the first threshold, the second threshold, the third threshold, etc.). For example, the protocol can specify that the triggering condition of the multi-panel measurement is that the signal quality of the serving cell of the terminal device is less than a certain threshold, and the default value of the threshold can be 20 decibels (dB), but the network device can dynamically adjust the value of the threshold, such as adjusting to 15 dB.

[0166] 803. In the case where the triggering condition of the multi-panel measurement is met, the terminal device measures the measurement objects corresponding to the first measurement target in parallel through the multiple antenna panels.

[0167] For example, after receiving the first configuration information from the network device, the terminal device can determine the specific trigger condition of the multi-antenna panel measurement based on the first configuration information, and then monitor whether the trigger condition of the multi-antenna panel measurement is met. If the trigger condition of the multi-antenna panel measurement is met, the terminal device can perform measurement on the measurement object corresponding to the first measurement target through multiple antenna panels in parallel.

[0168] It should be understood that if the trigger condition of the multi-antenna panel measurement is configured in the granularity of MO, the terminal device needs to perform measurement on the measurement object corresponding to the related MO through multiple antenna panels in parallel if the trigger condition of the multi-antenna panel measurement is met. For example, if the trigger condition of the multi-antenna panel measurement corresponds to the first MO, the terminal device needs to perform measurement on the measurement object corresponding to the first MO through multiple antenna panels in parallel if the trigger condition of the multi-antenna panel measurement is met. If the trigger condition of the multi-antenna panel measurement is configured in the granularity of the terminal device, the terminal device needs to perform measurement on the measurement object corresponding to all MOs (such as the first MO, the second MO, etc.) configured through multiple antenna panels in parallel if the trigger condition of the multi-antenna panel measurement is met.

[0169] As can be known from the above description in step 801, the trigger condition of the multi-antenna panel measurement can include one or more trigger conditions, and the trigger condition of the multi-antenna panel measurement being met can mean that any one of the one or more trigger conditions is met. Each trigger condition can include one or more of the following: the signal quality of the serving cell of the terminal device is less than a first threshold value, the absolute value of the change of the signal quality of the serving cell of the terminal device within a first time period is greater than a second threshold value, the time from the last time when the terminal device exits the multi-antenna panel measurement is greater than a third threshold value, the measurement object corresponding to the first processing target (MO) is configured to be measured by the multi-antenna panel, the terminal device triggers out-of-sync, and the terminal device triggers beam failure. That is, each of the above six conditions can be used as a trigger condition alone, or two, three, or more conditions can be combined as a trigger condition. It can be understood that different trigger conditions can be parallel and do not have a containing relationship, that is, one trigger condition can not be a subset of another trigger condition. In actual scenarios, the trigger condition can be flexibly configured according to related requirements.

[0170] In order to facilitate understanding of the embodiments of the present application, the above each condition is exemplarily described as follows.

[0171] Condition 1, the signal quality of the serving cell of the terminal device is less than a first threshold. Wherein, the serving cell of the terminal device can be PCell, PSCell or SCell, etc., and the embodiments of the present application do not limit this. That is, the signal quality of the serving cell of the terminal device being less than the first threshold can include multiple cases. For example, it can be that the signal quality of the PCell of the terminal device is less than the first threshold, or the signal quality of the PSCell of the terminal device is less than the first threshold, or the signal quality of the SCell of the terminal device is less than the first threshold. It should be understood that the three cases can be used as separate trigger conditions, or can be combined with other conditions as trigger conditions, and the specific conditions can be configured by the network device or specified by the protocol, and the embodiments of the present application do not limit this. Further, the signal quality of the serving cell of the terminal device can be the RSRP, RSRQ, SINR or other indicators that can measure the signal quality of the serving cell, and the embodiments of the present application do not limit this. It can be understood that when the signal quality of the serving cell of the terminal device is less than the first threshold, it can be considered that the terminal device is located at the edge of the cell or the channel condition of the cell is poor, and the mobility state change such as cell handover, deleting the current SCell, adding a new SCell, etc. can occur soon, therefore, the necessity of fast measurement by multiple panels is improved in this case, and the terminal device can perform fast measurement by multiple panels to obtain measurement results as soon as possible to perform cell handover, delete the current SCell or add a new SCell, etc. to ensure the service quality of the terminal device. For example, taking the RSRP of the PCell of the terminal device being less than the first threshold as an example, when the measurement result (RSRP) of the PCell of the terminal device is less than the first threshold, it can be considered that the terminal device is located at the edge of the cell or the channel condition of the cell is poor, and the required communication quality cannot be provided, therefore, the terminal device can perform fast measurement by multiple antenna panels to find a suitable neighbor cell and report to the access network device, so as to facilitate the access network device to perform switching related procedures.

[0172] It can be understood that the A2 event is that the signal quality of the serving cell of the terminal device is lower than an absolute threshold, and thus the signal quality of the serving cell of the terminal device being less than the first threshold can be marked by triggering of the A2 event, that is, when the terminal device triggers the A2 event, it is equivalent to the signal quality of the serving cell of the terminal device being less than the first threshold. When the A2 event is used as a separate triggering condition, when the terminal device triggers the A2 event, the terminal device can perform measurement in parallel through multiple antenna panels. The A2 event can be an A2 event associated with a PCell, a PSCell or an SCell of the terminal device, and can be configured by the base station. For example, when the access network device configures the terminal device with the triggering condition A2 event, it can indicate a certain MeasID, and when the A2 event triggered by the MeasID, the terminal device can perform measurement in parallel through multiple antenna panels.

[0173] Condition 2: the absolute value of the change of the signal quality of the serving cell of the terminal device in the first time period is greater than a second threshold. The serving cell of the terminal device can be a PCell, a PSCell or an SCell, and the like. That is, the absolute value of the change of the signal quality of the serving cell of the terminal device in the first time period being greater than the second threshold can include multiple cases. For example, the absolute value of the change of the signal quality of the PCell of the terminal device in the first time period can be greater than the second threshold, the absolute value of the change of the signal quality of the PSCell of the terminal device in the first time period can be greater than the second threshold, and the absolute value of the change of the signal quality of the SCell of the terminal device in the first time period can be greater than the second threshold. It should be understood that the three cases can be used as separate triggering conditions, or can be combined with other conditions as triggering conditions. The specific case can be configured by the network device or specified by the protocol, and the embodiments of the present application do not limit this. Further, the signal quality of the serving cell of the terminal device can be the RSRP, RSRQ, SINR or other indicators that can measure the signal quality of the serving cell. It can be understood that when the absolute value of the change of the signal quality of the serving cell of the terminal device in the first time period (such as 1 second, 5 seconds, 10 seconds, etc.) is greater than the second threshold, it indicates that the quality of the serving cell changes too fast, and the terminal device can be considered to be in a fast moving state, and the mobility state can change soon, such as cell switching, deleting the current SCell, adding a new SCell, and the like. Therefore, in this case, fast measurement can be performed through multiple panels to obtain measurement results as soon as possible for cell switching, deleting the current SCell or adding a new SCell, and the like, so as to ensure the service quality of the terminal device. For example, when the RSRP of the PCell of the terminal device changes by more than 3dB in 2 seconds, it can be considered that the terminal device is in a fast moving state, and the terminal device can perform fast measurement through multiple antenna panels.

[0174] It can be understood that in some possible implementation, only the case that the signal quality of the serving cell of the terminal device deteriorates can be considered, and the case that the signal quality of the serving cell of the terminal device improves can not be considered. That is, the absolute value of the change of the signal quality of the serving cell of the terminal device in the first time period is greater than the second threshold (such as 3 dB) can be changed to the case that the signal quality of the serving cell of the terminal device deteriorates by more than the second threshold in the first time period. For example, taking the RSRP of the PCell of the terminal device as an example, when the RSRP of the PCell of the terminal device deteriorates by more than 3 dB in 2 seconds, it can be considered that the terminal device is in a fast-moving state, and the signal quality of the serving cell is getting worse and worse, and the terminal device can perform fast measurement through multiple antenna panels.

[0175] Condition 3, the time from the last time the terminal device exits the multi-antenna panel measurement is greater than a third threshold. The third threshold can be understood as the maximum time allowed to fall back to single-antenna panel measurement, or can be understood as the maximum time allowed to exit the multi-antenna panel measurement. In the embodiments of the present application, condition 3 is mainly to balance the power consumption while meeting the demand for fast measurement. For example, previously in a certain case (such as meeting the exit condition of multi-antenna panel measurement), in order to save the power consumption of the terminal device, the terminal device switches from multi-panel fast measurement to single-panel measurement, but in order to meet the demand for fast measurement, the terminal device can switch back to multi-panel fast measurement after a period of single-panel measurement (such as the third threshold).

[0176] For example, the worse the signal quality of the serving cell of the terminal device, the more the terminal device usually needs to perform fast measurement (such as L3 measurement). Therefore, the third threshold can be associated with the signal quality of the serving cell of the terminal device, the worse the signal quality of the serving cell of the terminal device, the smaller the third threshold can be, and the better the signal quality of the serving cell of the terminal device, the larger the third threshold can be.

[0177] Condition 4, the measurement object corresponding to the first measurement object (MO) is configured as a multi-antenna panel measurement. The measurement object corresponding to the first MO can be a frequency point, a cell, and the like. For example, the network device can configure the measurement object corresponding to the relevant MO as a multi-antenna panel measurement or a single-antenna panel measurement. For example, the first configuration information can include a measurement target for multi-panel measurement, a frequency point for multi-panel measurement, a cell for multi-panel measurement, and the like. When the measurement target for multi-panel measurement includes the first MO, it can be indicated that the measurement object corresponding to the first MO is configured as a multi-antenna panel measurement. When the frequency point for multi-panel measurement or the cell for multi-panel measurement includes the measurement object corresponding to the first MO, it can be indicated that the measurement object corresponding to the first MO is configured as a multi-antenna panel measurement. In some possible implementation, the measurement object corresponding to the first measurement target can be a neighbor cell of the terminal device or a non-serving cell.

[0178] Condition 5, the terminal device triggers out-of-sync. For example, when the terminal device triggers out-of-sync through RLM evaluation, it indicates that the signal quality of the serving cell of the terminal device is poor, such as the radio link quality being lower than a corresponding threshold, at this time, it can be considered that the terminal device needs to perform multi-panel fast measurement.

[0179] Condition 6, the terminal device triggers beam failure. For example, when the terminal device triggers beam failure through beam failure detection (BFD), it indicates that the signal quality of the serving cell of the terminal device is poor, such as the signal quality of the serving beam being lower than a certain threshold, at this time, it can be considered that the terminal device needs to perform multi-panel fast measurement.

[0180] It can be understood that the above six conditions are only illustrative, and the embodiments of the present application are not limited thereto. For example, in another embodiment of the present application, more conditions can be included, such as triggering radio link failure (RLF). In actual situations, each condition can be used flexibly. For example, the above six conditions can be used as six independent trigger conditions. For another example, a plurality of the six conditions can be combined as one trigger condition. For example, the above condition 4 can be combined with the other five conditions as trigger conditions, and five trigger conditions can be obtained, that is, trigger condition 1 (condition 1+condition 4), trigger condition 2 (condition 2+condition 4), trigger condition 3 (condition 3+condition 4), trigger condition 4 (condition 5+condition 4), and trigger condition 5 (condition 6+condition 4).

[0181] It should be understood that the terminal device measures the measurement objects corresponding to the measurement targets in parallel through multiple antenna panels, that is, the terminal device simultaneously activates / turns on multiple antenna panels, each of which can independently form different receiving beams to simultaneously measure multiple directions of the beams of the measurement objects corresponding to the measurement targets. That is, the terminal device can simultaneously measure corresponding reference signals (such as SSB, CSI-RS, etc.) through at least two receiving beams. Wherein, the terminal device can simultaneously process (parallel processing) or time-division processing (serial processing) the signals received by different antenna panels. It should be noted that the frequency point of the measurement in the embodiments of the present application is not limited, which can be a frequency point in FR1 or a frequency point in FR2. For example, the above first MO can indicate a frequency point in FR2.

[0182] It should be noted that in the case of meeting the triggering condition of the multi-antenna panel measurement, the terminal device may have multiple cases for measuring the measurement objects corresponding to the first measurement target in parallel through multiple antenna panels. One case is that the terminal device determines to meet the triggering condition of the multi-antenna panel measurement when it starts to measure the measurement objects corresponding to the first measurement target, and then the terminal device can directly measure the measurement objects corresponding to the first measurement target in parallel through multiple antenna panels. Another case is that the terminal device can measure the measurement objects corresponding to the first measurement target through a single antenna panel before (such as before the first time), but the terminal device determines to meet the triggering condition of the multi-antenna panel measurement at the current time (such as the first time), and then the terminal device needs to switch from measuring the measurement objects corresponding to the first measurement target through a single antenna panel to measuring the measurement objects corresponding to the first measurement target in parallel through multiple antenna panels. For example, the terminal device determines not to meet the triggering condition of the multi-antenna panel measurement when it starts to measure the measurement objects corresponding to the first measurement target, and then the terminal device can default to use a single antenna panel for measurement, and then when the terminal device determines to meet the triggering condition of the multi-antenna panel measurement, the terminal device needs to switch from measuring the measurement objects corresponding to the first measurement target through a single antenna panel to measuring the measurement objects corresponding to the first measurement target in parallel through multiple antenna panels. For example, as shown in FIG. 9, the terminal device can measure through a single antenna panel in SMTC1 and SMTC2, and after SMTC2, the terminal device can determine to meet the triggering condition of the multi-antenna panel measurement, such as meeting the triggering condition (RSRP of Pcell < threshold 1), therefore, the terminal device can switch to measure in parallel through multiple antenna panels after that, such as SMTC3 and SMTC4 can switch to measure in parallel through multiple antenna panels.

[0183] In the above process, in a case where the multi-antenna panel measurement trigger condition is met, the terminal device needs to perform rapid measurement, such as rapid L3 measurement, through multiple antenna panels. In addition, the multi-antenna panel measurement trigger condition is mainly set for a scenario in which rapid measurement is needed, such as a scenario in which there is a need for cell switching or a scenario in which there is a need for SCell addition, so as to ensure the service quality of the terminal device.

[0184] Embodiment Two

[0185] Embodiment Two is the exit condition of the multi-antenna panel measurement and the related process flow of triggering the terminal device to exit the multi-antenna panel rapid measurement. In Embodiment Two, the network device can configure the exit condition of the multi-antenna panel measurement for the terminal device, and then the terminal device can monitor whether the exit condition of the multi-antenna panel measurement is met. In a case where the exit condition of the multi-antenna panel measurement is met, the terminal device can perform measurement through a single antenna panel. Specifically, refer to FIG. 10, which is a flowchart of another measurement method disclosed in the embodiments of the present application. As shown in FIG. 10, the method can include but is not limited to the following steps:

[0186] 1001. The network device determines second configuration information, which is used to determine the exit condition of the multi-antenna panel measurement.

[0187] To facilitate understanding of the second configuration information, the exit condition of the multi-antenna panel measurement is first described by way of example. As the name implies, the exit condition of the multi-antenna panel can be understood as a condition for triggering the terminal device to exit the multi-antenna panel to perform parallel measurement, or can be understood as a condition for triggering the terminal device to start / activate a single antenna panel to perform measurement.

[0188] In the embodiments of the present application, the exit condition of the multi-antenna panel measurement can include that the signal quality of the serving cell of the terminal device is greater than a fourth threshold, the terminal device reports at least one measurement report in which the signal quality of the measurement object corresponding to the first MO is greater than a fifth threshold, the terminal device reports at least one measurement report in which the signal quality of the measurement object corresponding to the second MO is greater than a sixth threshold, the terminal device has performed multi-antenna panel measurement on the measurement object corresponding to the first MO for a first time length, and the terminal device triggers one or more of the first events. That is, the above-mentioned items can be used as an exit condition for triggering the exit of the multi-antenna panel measurement, or multiple items can be combined to serve as an exit condition for triggering the exit of the multi-antenna panel measurement.

[0189] In some possible implementation, the exit condition of the multi-antenna panel measurement can include one or more exit conditions, and the terminal device exits the multi-antenna panel measurement or performs the single-antenna panel measurement when any one of the one or more exit conditions is met. Each exit condition can include one or more of the following: the signal quality of the serving cell of the terminal device is greater than a fourth threshold, the terminal device reports a measurement report in which the signal quality of the measurement object corresponding to the first MO is greater than a fifth threshold at least once, the terminal device reports a measurement report in which the signal quality of the measurement object corresponding to the second MO is greater than a sixth threshold at least once, the terminal device has performed the multi-antenna panel measurement on the measurement object corresponding to the first MO for a first time length, and the terminal device triggers a first event.

[0190] In some possible implementation, the terminal device has performed the multi-antenna panel measurement on the measurement object corresponding to the first MO for a first time length can be combined with other conditions, for example, whether a neighbor cell meeting a condition is found. For example, the terminal device has performed the multi-antenna panel measurement on the measurement object corresponding to the first MO for a first time length can be that the terminal device has performed the multi-antenna panel measurement on the measurement object corresponding to the first MO for a first time length and has not found a neighbor cell with a signal quality greater than a seventh threshold, or the terminal device has performed the multi-antenna panel measurement on the measurement object corresponding to the first MO for a first time length and has found a neighbor cell with a signal quality greater than an eighth threshold.

[0191] As can be seen from the above description of the exit condition of the multi-antenna panel measurement, the exit condition of the multi-antenna panel measurement has high flexibility. In some possible implementation, the network device can send related configuration information / auxiliary information (such as second configuration information) to the terminal device to facilitate the terminal device to determine the exit condition of the multi-antenna panel measurement. For example, the network device can determine the second configuration information, and the second configuration information can be used to determine the exit condition of the multi-antenna panel measurement. For example, the second configuration information can include parameters used to determine the exit condition of the multi-antenna panel measurement.

[0192] In some possible implementation, the second configuration information can include one or more of the following: first event information (such as A3, A4, A5, A6, etc.), threshold information related to the exit condition, and the like. The threshold information can include the fourth threshold, the fifth threshold, the sixth threshold, the seventh threshold, the eighth threshold, the first time length, and the like.

[0193] Exemplarily, the first event information can indicate a related first event. The first event can include one or more events, such as one or more of A3, A4, A5, A6, etc. When the terminal device triggers the first event (such as triggers any one of A3, A4, A5, A6, etc.), the terminal device can be triggered to exit the multi-antenna panel measurement.

[0194] It should be noted that the fourth threshold, the fifth threshold, the sixth threshold, the seventh threshold, the eighth threshold, and the first time length described above can be fixed values or variable values. For example, the network device can dynamically adjust the above-mentioned thresholds according to actual conditions, such as the signal quality of the serving cell of the terminal device. In addition, the above-mentioned thresholds can be the same or different. For example, the fifth threshold and the sixth threshold described above can be the same or different.

[0195] In the embodiments of the present application, the terminal device can also report capability information to the network device. The capability information can include related information of the antenna panel of the terminal device, such as the number of antenna panels included by the terminal device, and the frequency band or frequency point supported by each antenna panel, etc.

[0196] It should be understood that the network device can be an access network device or other device, and the embodiments of the present application do not limit this.

[0197] 1002. The network device sends second configuration information to the terminal device.

[0198] After determining the second configuration information, the network device can send the second configuration information to the terminal device. Correspondingly, the terminal device can receive the second configuration information from the network device.

[0199] It can be understood that the manner in which the network device sends the second configuration information to the terminal device can include various manners, and the embodiments of the present application do not limit this. For example, the second configuration information can be carried in certain downlink control signaling / messages (such as RRC signaling / messages), such as in RRC signaling / messages. Exemplarily, assuming that a certain downlink control signaling / message can include field 1, field 2, and field 3, field 1 can be a specific fourth threshold, field 2 can be a specific fifth threshold, and field 3 can be a specific fifth threshold, etc.

[0200] It should be noted that in the embodiments of the present application, the network device can configure the exit condition of the multi-panel measurement in different granularity. For example, the network device can configure the exit condition of the multi-panel measurement in the granularity of the terminal device, so that each terminal device can have a corresponding exit condition of the multi-panel measurement, which can be applicable to all measurements of the corresponding terminal device, or can be applicable to all L3 measurements of the corresponding terminal device, etc. For another example, the network device can configure the exit condition of the multi-panel measurement in the granularity of the MO, so that each MO can have a corresponding exit condition of the multi-panel measurement, and the second configuration information can be used to determine the exit condition of the multi-panel measurement corresponding to the first processing target. For another example, the network device can configure the exit condition of the multi-panel measurement in the granularity of the cell, frequency point, frequency band, etc., which is not limited in the embodiments of the present application.

[0201] For example, in the case where the network device configures the exit condition of the multi-panel measurement in the granularity of the MO, the second configuration information can be associated with the corresponding MO, such as the first MO. In this case, when the network device sends the second configuration information to the terminal device, the network device can carry the identification information of the first MO, such as the measurement identification (MeasID) corresponding to the first MO, to indicate that the second configuration information can be used to determine the exit condition of the multi-panel measurement corresponding to the first MO.

[0202] It can be understood that the steps 1001 and 1002 are optional. For example, in some possible implementation, the exit condition of the multi-panel measurement can be predefined, such as can be specified by the protocol, including specifying a specific threshold (such as the fourth threshold, the fifth threshold, the sixth threshold, etc.) and the like. For another example, in some possible implementation, the exit condition of the multi-panel measurement can be specified by the protocol, but the network device can dynamically configure the related parameters (such as the fourth threshold, the fifth threshold, the sixth threshold, etc. described above). For example, the protocol can specify that the signal quality of the serving cell of the terminal device is greater than a certain threshold as the exit condition of the multi-panel measurement, but the specific threshold can be configured by the network device. For another example, in some possible implementation, the exit condition of the multi-panel measurement can be specified by the protocol, and the protocol can specify a default threshold, but the network device can dynamically configure the related parameters (such as the fourth threshold, the fifth threshold, the sixth threshold, etc. described above). For example, the protocol can specify that the signal quality of the serving cell of the terminal device is greater than a certain threshold as the exit condition of the multi-panel measurement, and the default value of the threshold can be 30 decibels (dB), but the network device can dynamically adjust the value of the threshold, such as adjusting to 35 dB.

[0203] 1003. In the case where the exit condition of the multi-panel measurement is met, the terminal device measures the measurement object corresponding to the first measurement target by using a single antenna panel.

[0204] For example, the terminal device can monitor whether the exit condition of the multi-antenna panel measurement is met, and in the case that the exit condition of the multi-antenna panel measurement is met, the terminal device can measure the measurement object corresponding to the first measurement target by using a single antenna panel, or the terminal device can exit / end the multi-antenna panel measurement. For example, after receiving the second configuration information from the network device, the terminal device can determine the exit condition of the specific multi-antenna panel measurement based on the second configuration information, and then the terminal device can monitor whether the exit condition of the multi-antenna panel measurement is met. In the case that the exit condition of the multi-antenna panel measurement is met, the terminal device can measure the measurement object corresponding to the first measurement target by using a single antenna panel.

[0205] It should be understood that if the exit condition of the multi-antenna panel measurement is configured in the granularity of MO, in the case that the exit condition of the multi-antenna panel measurement is met, the terminal device can measure the measurement object corresponding to the related MO by using a single antenna panel. For example, if the exit condition of the multi-antenna panel measurement is corresponding to the first MO, in the case that the exit condition of the multi-antenna panel measurement is met, the terminal device can measure the measurement object corresponding to the first MO by using a single antenna panel. If the exit condition of the multi-antenna panel measurement is configured in the granularity of the terminal device, in the case that the exit condition of the multi-antenna panel measurement is met, the terminal device can measure the measurement object corresponding to all MOs (such as the first MO, the second MO, etc.) configured by using a single antenna panel.

[0206] As can be known from the related description in the above step 1001, the exit condition of the multi-antenna panel measurement can include one or more exit conditions, and the exit condition of the multi-antenna panel measurement being met can mean that any one of the one or more exit conditions is met, and each exit condition can include one or more of the following: the signal quality of the serving cell of the terminal device is greater than a fourth threshold value, the terminal device reports at least one measurement report of the signal quality of the measurement object corresponding to the first MO being greater than a fifth threshold value, the terminal device reports at least one measurement report of the signal quality of the measurement object corresponding to the second MO being greater than a sixth threshold value, the terminal device has performed multi-antenna panel measurement on the measurement object corresponding to the first MO for a first time length, and the terminal device triggers the first event for reporting. That is, for the above five conditions, each can be used as an exit condition alone, or two, three or more conditions can be combined as an exit condition. It can be understood that different exit conditions can be parallel and do not have a containing relationship, that is, one exit condition can not be a subset of another exit condition. In actual scenarios, the exit condition can be flexibly configured according to related requirements.

[0207] For the convenience of understanding the embodiments of the present application, the above each condition is exemplarily described as follows.

[0208] Condition 1, the signal quality of the serving cell of the terminal device is greater than a fourth threshold. Wherein, the serving cell of the terminal device can be PCell, PSCell or SCell, etc., which is not limited in the embodiments of the present application. That is, the signal quality of the serving cell of the terminal device being greater than the fourth threshold can include multiple cases. For example, it can be that the signal quality of the PCell of the terminal device is greater than the fourth threshold, or the signal quality of the PSCell of the terminal device is greater than the fourth threshold, or the signal quality of the SCell of the terminal device is greater than the fourth threshold. It should be understood that the above three cases can be used as separate exit conditions, or can be combined with other conditions as exit conditions, and the specific conditions can be configured by the network device or specified by the protocol, which is not limited in the embodiments of the present application. Further, the signal quality of the serving cell of the terminal device can be the RSRP, RSRQ, SINR or other indicators that can measure the signal quality, which is also not limited in the embodiments of the present application. It can be understood that when the signal quality of the serving cell of the terminal device is greater than the fourth threshold, it can be considered that the terminal device is close to the cell center, and the mobility state change such as cell handover, deleting the current SCell, adding a new SCell, etc. can not occur in a short time, therefore, in this case, the fast measurement through multiple panels is not needed, and the measurement through a single panel can be performed. Exemplarily, taking the RSRP of the PCell of the terminal device being greater than the fourth threshold as an example, when the measurement result (RSRP) of the PCell of the terminal device is greater than the fourth threshold, it can be considered that the terminal device is close to the cell center, and therefore, the terminal device can perform the measurement through a single antenna panel.

[0209] Condition 2, the terminal device reports at least one measurement report of the signal quality of the measurement object corresponding to the first MO being greater than the fifth threshold value, or the terminal device completes at least one report of the measurement result of the signal quality of the measurement object corresponding to the first MO being greater than the fifth threshold value. For example, when the terminal device performs measurement on the measurement object corresponding to the first MO in parallel through multiple antenna panels, if at least one measurement report of the signal quality of the measurement object corresponding to the first MO being greater than the fifth threshold value is reported, it can be considered that the access network device already has a candidate cell for cell switching, SCell addition, and the like. Therefore, in this case, the necessity of the UE performing fast measurement through multiple panels is reduced, and the terminal device can exit the multiple-panel fast measurement to save power consumption. For example, the terminal device discovers and reports one or more neighbor cells with signal quality greater than the fifth threshold value at the frequency point corresponding to the first MO, and in this case, it can be considered that the terminal device does not need to perform multiple-panel fast measurement. It can be understood that the number of times that the terminal device reports the measurement report of the signal quality of the measurement object corresponding to the first MO being greater than the fifth threshold value can be one or multiple times, and the specific reporting times can be pre-defined by a protocol or indicated by the access network device. In some possible implementation manners, the measurement object corresponding to the first measurement target can be a neighbor cell or a non-serving cell of the terminal device.

[0210] Condition 3, the terminal device reports at least one measurement report of the signal quality of the measurement object corresponding to the second MO being greater than the sixth threshold value, or the terminal device completes at least one report of the measurement result of the signal quality of the measurement object corresponding to the second MO being greater than the sixth threshold value. For example, the terminal device can be configured with the first MO and the second MO, and during the process of measuring the measurement object corresponding to the first MO in parallel through multiple antenna panels, if at least one measurement report of the signal quality of the measurement object corresponding to the second MO being greater than the sixth threshold value is reported, it can be considered that the access network device already has a candidate cell for cell switching, SCell addition, and the like. Therefore, in this case, the terminal device can exit the multiple-panel fast measurement and measure the measurement object corresponding to the first MO through a single panel to save power consumption. For example, the terminal device discovers and reports one or more neighbor cells with signal quality greater than the fifth threshold value at the frequency point corresponding to the second MO, and in this case, it can be considered that the terminal device does not need to perform multiple-panel fast measurement. It can be understood that the number of times that the terminal device reports the measurement report of the signal quality of the measurement object corresponding to the second MO being greater than the sixth threshold value can be one or multiple times, and the specific reporting times can be pre-defined by a protocol or indicated by the access network device.

[0211] Condition 4: The terminal device has performed multi-antenna panel measurement on the measurement object corresponding to the first MO for a first time length. The first time length can be understood as the time during which the terminal device needs to perform multi-antenna panel measurement. In the embodiments of the present application, condition 4 is mainly to balance the power consumption while meeting the demand for fast measurement, so as to avoid the terminal device always measuring the measurement object corresponding to the first measurement target through multiple antenna panels in parallel. For example, the first time length can be 10 seconds. When the terminal device has performed 10 seconds of multi-panel fast measurement, the terminal device can fall back to single-panel measurement. When the multi-panel fast measurement is triggered again, the terminal device can perform 10 seconds of multi-panel fast measurement again, and then can fall back to single-panel measurement again.

[0212] For example, the first time length can be related to the search and measurement time of the measurement object (frequency point) corresponding to the first MO. For example, in the related standard, the total identification time (Tidentify_inter_without_index) of an FR2 cell can be the sum of the search time (Tsearch_inter) of the PSS (primary synchronization signal) / SSS (secondary synchronization signal) signal and the SSB measurement time (TSSB_measurement_period_inter). Wherein, Tsearch_inter is related to the SMTC period, DRX configuration, and MGRP configuration, and can be referred to the description in the related standard. TSSB_measurement_period_inter can also be referred to the calculation formula in the standard. The first time length can be N times of Tidentify_inter_without_index, and N can be a positive integer. That is, after the terminal device performs one or more multi-panel fast measurements on the measurement object (frequency point) corresponding to the first MO, the terminal device can exit the multi-panel fast measurement. PSS / SSS_sync_inter PSS / SSS_sync_inter The first time length can be N times of Tidentify_inter_without_index, and N can be a positive integer. That is, after the terminal device performs one or more multi-panel fast measurements on the measurement object (frequency point) corresponding to the first MO, the terminal device can exit the multi-panel fast measurement.

[0213] ​It is understandable that the fact that the terminal device has performed a first-duration multi-antenna panel measurement on the measurement object corresponding to the first MO can be combined with other conditions, such as whether a neighboring cell that meets the conditions has been found. For example, the fact that the terminal device has performed a first-duration multi-antenna panel measurement on the measurement object corresponding to the first MO can specifically mean that the terminal device has performed a first-duration multi-antenna panel measurement on the measurement object corresponding to the first MO and has not found a neighboring cell with a signal quality greater than the seventh threshold. This situation indicates that the terminal device has performed a relatively long multi-panel rapid measurement but has not found a neighboring cell that meets the conditions. The probability of finding a neighboring cell that meets the conditions by continuing to perform multi-panel rapid measurement on the measurement object corresponding to the first MO may be low. Therefore, the terminal device does not need to continue to perform multi-panel rapid measurement, otherwise it will increase power consumption unnecessarily. For another example, the terminal device has performed a multi-antenna panel measurement for a first duration on the measurement object corresponding to the first MO. Specifically, this means that the terminal device has performed a multi-antenna panel measurement for a first duration on the measurement object corresponding to the first MO and has found a neighboring cell with a signal quality greater than the eighth threshold. This situation indicates that the terminal device has found one or more neighboring cells that meet the conditions through multi-panel rapid measurement within the first duration. It can be considered that the access network device already has candidate cells for operations such as cell handover and SCell addition. The terminal device can switch to single-panel measurement.

[0214] In some possible implementations, the first duration may not be associated with the first MO. That is, condition 4 can be that the terminal device has performed a first duration of multi-antenna panel measurement. In this case, the total duration for which the terminal device performs parallel measurements on all the configured MOs (such as the first MO, the second MO, etc.) through multiple antenna panels can be counted. The maximum total duration for which the terminal device performs parallel measurements on all the configured MOs (such as the first MO, the second MO, etc.) through multiple antenna panels can be the first duration.

[0215] Condition 5, the terminal device triggers a first event report. Exemplarily, the first event can be an event of discovering a neighbor cell with good signal quality, such as A3, A4, A5, A6 events, etc. Therefore, when the terminal device triggers the first event report, it can be indicated that the terminal device discovers a neighbor cell with good quality, and it can be considered that the access network device already has a candidate cell for cell switching, SCell addition, etc. In this case, the terminal device can exit the multi-panel fast measurement and perform measurement on the measurement object corresponding to the first MO by using a single panel to save power consumption. The first event report can be a first event report associated with the first MO, or a first event report associated with another MO (such as a second MO). For example, when the terminal device triggers the first event report associated with the first MO, it can be indicated that the terminal device discovers a neighbor cell meeting the requirements in the measurement object (such as a frequency point) corresponding to the first MO. Accordingly, it can be considered that the access network device already has a candidate cell for cell switching, SCell addition, etc. Therefore, the terminal device can exit the multi-panel fast measurement and perform measurement on the measurement object corresponding to the first MO by using a single panel to save power consumption. For another example, when the terminal device triggers the first event report associated with another MO (such as a second MO), it can be indicated that the terminal device discovers a neighbor cell meeting the requirements in the measurement object (such as a frequency point) corresponding to the second MO. Accordingly, it can be considered that the access network device already has a candidate cell for cell switching, SCell addition, etc. Therefore, the terminal device can exit the multi-panel fast measurement and perform measurement on the measurement object corresponding to the first MO by using a single panel to save power consumption.

[0216] It can be understood that the first event can be configured by the access network device or predefined by a protocol. For example, when the access network device configures the terminal device with the exit condition A3 event corresponding to the first MO, it can indicate a certain MeasID. When the A3 event corresponding to the MeasID is triggered, the terminal device can exit the multi-panel fast measurement and perform measurement on the measurement object corresponding to the first MO by using a single panel.

[0217] It can be understood that the above five conditions are only exemplary, and embodiments of the present application are not limited thereto. For example, in another embodiment of the present application, more conditions can be included. In actual situations, each condition can be used flexibly, for example, the above five conditions can be used as five independent trigger conditions. For another example, multiple conditions among the five conditions can be combined as one trigger condition.

[0218] It should be noted that in the case of meeting the exit condition of multi-antenna panel measurement, the terminal device can measure the measurement object corresponding to the first measurement target through a single antenna panel in multiple cases. In one case, the terminal device determines to meet the exit condition of multi-antenna panel measurement when it starts to measure the measurement object corresponding to the first measurement target, and then the terminal device can directly measure the measurement object corresponding to the first measurement target through a single antenna panel. In another case, the terminal device can measure the measurement object corresponding to the first measurement target through multiple antenna panels in parallel before (for example, before the second time), but the terminal device determines to meet the exit condition of multi-antenna panel measurement at present (for example, at the second time), and then the terminal device can switch from measuring the measurement object corresponding to the first measurement target through multiple antenna panels in parallel to measuring the measurement object corresponding to the first measurement target through a single antenna panel, that is, the terminal device can exit / end the multi-antenna panel measurement. For example, the terminal device determines not to meet the exit condition of multi-antenna panel measurement when it starts to measure the measurement object corresponding to the first measurement target, and then the terminal device can measure by default through multiple antenna panels in parallel, and then when the terminal device determines to meet the exit condition of multi-antenna panel measurement, the terminal device needs to switch from measuring the measurement object corresponding to the first measurement target through multiple antenna panels in parallel to measuring the measurement object corresponding to the first measurement target through a single antenna panel. For example, as shown in FIG. 11, in SMTC1 and SMTC2, the terminal device can measure through multiple antenna panels in parallel, and after SMTC2, the terminal device can determine to meet the exit condition of multi-antenna panel measurement, for example, meet the exit condition (RSRP of Pcell>threshold 2), and therefore the terminal device can switch to measure through a single antenna panel after that, for example, SMTC3 and SMTC4 can switch to measure through a single antenna panel.

[0219] In the above process, in the case of meeting the exit condition of multi-antenna panel measurement, the terminal device can measure through a single antenna panel. Moreover, the above exit condition of multi-antenna panel measurement is mainly set for a scenario that does not need to perform fast measurement, for example, a scenario that does not exist cell switching demand, a scenario that does not exist SCell addition demand, etc., which can save power consumption while ensuring the quality of service of the terminal device.

[0220] It can be understood that the embodiment corresponding to FIG. 8 and the embodiment corresponding to FIG. 9 can be combined, that is, the triggering condition of the multi-antenna panel measurement, the exit condition of the multi-antenna panel measurement, the process of triggering the terminal device to perform the multi-antenna panel fast measurement, and the process of triggering the terminal device to exit the multi-antenna panel fast measurement can be combined. For example, the first configuration information and the second configuration information can be the same configuration information, which can be used to determine the triggering condition of the multi-antenna panel measurement and / or the exit condition of the multi-antenna panel measurement. For example, based on the triggering condition of the multi-antenna panel measurement and the exit condition of the multi-antenna panel measurement, the terminal device can alternately use the multi-antenna panel measurement and the single-antenna panel measurement. For example, when the triggering condition of the multi-antenna panel measurement is met, the terminal device can perform measurement through multiple antenna panels in parallel, and then when the exit condition of the multi-antenna panel measurement is met, the terminal device can switch from measurement through multiple antenna panels in parallel to measurement through a single antenna panel, and then when the triggering condition of the multi-antenna panel measurement is met, the terminal device can switch from measurement through a single antenna panel to measurement through multiple antenna panels in parallel, and so on.

[0221] It can also be understood that the technical solutions provided by the embodiments of the present application can be used in the architecture of an open access network. The operations performed by the network device / access network device can be performed by a CU, a DU, a CU-CP, a RIC (such as a near-RT RIC), and the like, and the information sent by the terminal device to the access network device can be sent to a CU, a DU, a CU-CP, or a RIC (such as a near-RT RIC), and the like, and the embodiments of the present application do not limit this. For example, the access network device can configure the measurement target of FR2, the related configuration information (such as the first configuration information and the second configuration information) and the like for the terminal device through the CU, the DU or the CU-CP, or can configure the measurement target of FR2, the related configuration information (such as the first configuration information and the second configuration information) and the like for the terminal device through the RIC. For another example, when the terminal device triggers a related event (such as an A2 event), the terminal device can report to the CU, the DU, the CU-CP or the RIC.

[0222] It should be noted that the related information (that is, the same information or similar information) and the related description in the above different embodiments can be mutually referred to.

[0223] The above mainly introduces the measurement method provided by the embodiments of the present application. It can be understood that the terminal device and the network device described above can contain the hardware structure and / or software module corresponding to the execution of each function in order to realize the corresponding functions described above. The units and steps of each example described in combination with the embodiments disclosed herein can be implemented in hardware or a combination of hardware and computer software. Whether a certain function is implemented in hardware or computer software driven hardware depends on the specific application of the technical solution and the design constraints. Professional technicians can use different methods for each specific application to implement the described functions, but such implementation should not be considered beyond the scope of the embodiments of the present application.

[0224] The embodiments of the present application can divide the functional modules of the terminal device and the network device according to the above method examples. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one module. The integrated module can be implemented in the form of hardware or software functional module. It should be noted that the division of the modules by the embodiments of the present application is illustrative, and is only a logical functional division. Actual implementation can have another division method.

[0225] In the case of dividing each functional module according to each function, Fig. 12 shows a possible structural schematic diagram of a communication device 1200. The communication device 1200 includes a processing unit 1201, and the communication device 1200 can also include a receiving unit 1202. In a possible design, the communication device 1200 can be the terminal device described above, or can be a chip in the terminal device, or can be a processing system, chip system, circuit or functional module in the terminal device, etc. The terminal device can include multiple antenna panels. Among them:

[0226] The processing unit 1201 is configured to perform measurement on a measurement object corresponding to a first measurement object MO in parallel through multiple antenna panels in a case where a trigger condition of multi-antenna panel measurement is met.

[0227] For example, the processing unit 1201 performs measurement on the measurement object corresponding to the first measurement object MO in parallel through multiple antenna panels. Specifically, the processing unit 1201 can receive signals in parallel through multiple antenna panels, and then the processing unit 1201 can perform correlation processing on the signals received by the multiple antenna panels to obtain measurement results.

[0228] In a possible implementation, the processing unit 1201 is further configured to perform measurement on the measurement object corresponding to the first MO through a single antenna panel in a case where an exit condition of multi-antenna panel measurement is met.

[0229] In a possible implementation, the trigger condition of the multi-antenna panel measurement includes one or more of the following: the signal quality of the serving cell of the terminal device is less than a first threshold, the absolute value of the change of the signal quality of the serving cell of the terminal device within a first time period is greater than a second threshold, the time from the last time when the terminal device exits the multi-antenna panel measurement is greater than a third threshold, the measurement object corresponding to the first MO is configured as the multi-antenna panel measurement, the terminal device triggers out-of-sync, and the terminal device triggers beam failure.

[0230] In a possible implementation, the trigger condition of the multi-antenna panel measurement includes one or more trigger conditions, and the trigger condition of the multi-antenna panel measurement is met when any one of the one or more trigger conditions is met. Each of the one or more trigger conditions includes one or more of the following: the signal quality of the serving cell of the terminal device is less than a first threshold, the absolute value of the change of the signal quality of the serving cell of the terminal device within a first time period is greater than a second threshold, the time from the last time when the terminal device exits the multi-antenna panel measurement is greater than a third threshold, the measurement object corresponding to the first MO is configured as the multi-antenna panel measurement, the terminal device triggers out-of-sync, and the terminal device triggers beam failure.
