[0129] In the related art, inter-cell beam management supports configuring the SSB of non-serving cells as beam measurement reference signals, and the terminal can report the L1-RSRP measurement results of the SSB of non-serving cells. Figure 1 As shown, the terminal can receive the beam of the non-service cell, and the serving cell can select the beam of the non-service cell to serve the terminal.

[0130] The inter-cell beam management mechanism includes the following processes:

[0131] 1. The network side configures the beam measurement reference signal associated with the channel state information (CSI) reporting, the time and frequency resources used for CSI reporting, and other information;

[0132] 2. The terminal side measures the reference signal according to the configuration of the network side, and reports the indexes and L1-RSRP of K reference signals, where K is configured by the network side, and the K reference signals may include the reference signal of the serving cell and the reference signal of the non-serving cell.

[0133] In the above process, the terminal performs L1 measurement on the configured reference signal according to the configuration of the network side, and then directly reports the indexes and L1-RSRP of K reference signals according to the reporting configuration. In other words, the terminal needs to report K measurement results in any case. However, in some scenarios, for example, the candidate cell included in the measurement configuration cannot be measured, or the signal quality of the candidate cell is poor, which will cause unnecessary beam measurement and measurement reporting, wasting the signaling overhead of the terminal.

[0134] Based on this, in various embodiments of the present application, the CU of the first network device sends first information to the DU of the first network device, and the DU of the first network device sends first information to the terminal, wherein the first information represents the L1 measurement configuration, including at least one of the following: a first condition, the first condition represents the condition for triggering L1 measurement; a second condition, the second condition represents the condition for triggering L1 measurement reporting or prohibiting L1 measurement reporting; second information, the second information represents the L1 measurement configuration. In the above scheme, the network device can configure the conditions for triggering L1 measurement, as well as the conditions for triggering L1 measurement reporting or prohibiting L1 measurement reporting, which can reduce unnecessary L1 measurements and measurement reports, thereby saving energy consumption and signaling overhead of the terminal.

[0135] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0136] The present application embodiment provides a measurement method, which is applicable to a terminal, which may include a mobile phone, a tablet computer, a wearable device, a laptop computer, etc. Figure 2 As shown, the method includes:

[0137] Step 201: Receive first information sent by a first network device.

[0138] The first information represents a layer 1 L1 measurement configuration, including at least one of the following:

[0139] A first condition, wherein the first condition represents a condition for triggering L1 measurement;

[0140] A second condition, wherein the second condition represents a condition for triggering L1 measurement reporting or prohibiting L1 measurement reporting;

[0141] The second information represents an L1 measurement configuration.

[0142] Here, the first network device is a network device that provides services for the terminal, which can be understood as a service base station. Specifically, the first information can be sent by the DU of the first network device, and the first information at least includes the first condition; a network device can be composed of a CU and one or more DUs; CU and DU are both logical units; a CU can control or connect multiple DUs; a DU has one or more cells, and a cell is only carried by one DU.

[0143] The condition (Criterion) triggering the L1 measurement can also be understood as an event triggering the L1 measurement, or understood as an L1 measurement event.

[0144] The L1 measurement configuration may include at least one of the following: reference signal configuration, channel state information reference signal (CSI-RS, Channel State Information-Reference Signal) configuration and transmission configuration indication (TCI, Transmission Configuration Indicator) related configuration. Among them, the reference signal configuration is used to configure the reference signal of the serving cell and / or configure the reference signal of the candidate cell. The reference signal may include SSB and / or CSI-RS.

[0145] It should be noted that the first information is used for the terminal to autonomously decide whether to perform L1 measurement and / or L1 measurement reporting. Since the first network device does not know the specific signal reception situation of the terminal, the terminal autonomously decides whether to perform L1 measurement based on the first information, which can avoid the terminal performing meaningless L1 measurement (unnecessary L1 measurement) or starting measurement too late, which may cause a handover failure.

[0146] In order to reduce unnecessary L1 measurements, in one embodiment, the second information includes at least one of the following:

[0147] Measurement object;

[0148] Reference signal configuration;

[0149] Transmission configuration indication TCI related configuration;

[0150] A first index, wherein the first index includes at least one of the following: an index of a cell, an index of a beam, and an index of an LTM configuration;

[0151] The cell or cell group to be tested.

[0152] Here, the measurement object refers to the object for L1 measurement performed by the terminal, and specifically may be the subcarrier spacing and / or time domain position and / or frequency domain position of the reference signal.

[0153] The reference signal configuration is used to configure the reference signal of the serving cell and / or the reference signal of the candidate cell. The reference signal may include SSB and / or CSI-RS.

[0154] The cells to be tested include serving cells and / or candidate cells; the cell group to be tested may include at least one candidate cell.

[0155] Considering that continuous LTM faces the situation that the configured candidate cell may not necessarily be able to measure the reference signal, or the signal of the configured candidate cell is poor, resulting in too much overhead for the terminal to continuously measure, in order to reduce unnecessary L1 measurements, reduce L1 measurement overhead and power consumption, in one embodiment, the first condition includes at least one of the following:

[0156] The signal quality of the serving cell is less than or equal to a first set threshold;

[0157] The L1 measurement result indicates that the decrease value of the signal quality of the serving cell is greater than or equal to the second set threshold;

[0158] Arrive at the first time;

[0159] The first timer times out;

[0160] The L3 measurement result of the neighboring cell is greater than the third set threshold;

[0161] The L3 measurement result of the serving cell is less than a fourth set threshold;

[0162] L3 measurement results meet the reporting event requirements;

[0163] The moving distance of the terminal is greater than the set distance;

[0164] The terminal changes the cell group or changes the CU.

[0165] Here, in the case where the first condition includes at least two of the above items, if all conditions included in the first condition are currently met, then L1 measurement is triggered.

[0166] The signal quality of the serving cell is less than or equal to the first set threshold, which can be understood as the value of the signal quality parameter of the serving cell is less than or equal to the first set threshold. The threshold is also called a threshold value (THRES) or (threshold); the signal quality parameter includes at least one of the following: RSRP, reference signal reception quality (RSRQ, Reference Signal ReceivingQuality), signal to interference plus noise ratio (SINR, Signal to Interference plus Noise Ratio). The signal quality of the serving cell is less than or equal to the first set threshold, including: the signal quality of the serving cell in at least N L1 measurement results is less than or equal to the first set threshold, and / or, the signal quality of the serving cell within the first set time is less than or equal to the first set threshold; N is a positive integer. For example, the RSRP of the serving cell in at least N L1 measurement results is less than or equal to the first set threshold, or, the RSRP of the serving cell within the first set time is less than or equal to the first set threshold.

[0167] The reduction value of the signal quality of the serving cell is greater than or equal to the second set threshold, which can also be understood as a sudden drop in the signal quality of the serving cell. The reduction value can also be called a reduction amount, a drop amount or a drop value. Among them, the reduction value can be understood as the difference between the first value of the signal quality parameter and the second value of the signal quality parameter, the second value is obtained before the first value, and the first value is greater than the second data. The sudden drop in the signal quality of the serving cell includes: the signal quality of the serving cell drops suddenly within a preconfigured time, or, in M ​​L1 measurements, the signal quality of the serving cell drops suddenly; the preconfigured time can be an integer multiple of the measurement period, and M is the preconfigured number of measurements. For example, within the preconfigured time, the difference between the first RSRP and the second RSRP of the serving cell is greater than or equal to the second set threshold, or, in M ​​L1 measurements, the difference between the first RSRP and the second RSRP of the serving cell is greater than or equal to the second set threshold. The second RSRP and the first RSRP are measured based on the same reference signal, and the second RSRP is obtained before the first RSRP, and the first RSRP is greater than the first RSRP.

[0168] The first time may be an absolute time, or a moment when the first information is received.

[0169] The timeout of the first timer can be understood as the expiration of the first timer. When the first time is an absolute time, the first timer is started at the first time. When the first timer times out, it indicates that the first condition is met, triggering L1 measurement. When the first time is the moment of receiving the first information, the first timer is started when the first information is received, and the first timer starts timing. When the first timer times out, it indicates that the first condition is met. By configuring the first time and / or the first timer, ping-pong switching caused by L1 measurement jitter can be avoided when the terminal is still in the cell center after just completing the cell switching.

[0170] It should be noted that, when the first condition includes that the signal quality of the serving cell is less than or equal to the first set threshold and the first timer times out, the terminal starts the first timer when completing random access, and does not trigger L1 measurement and reporting if the first timer has not timed out; when the first timer times out, if the signal quality of the serving cell in at least N L1 measurement results is less than or equal to the first set threshold, the terminal performs L1 measurement, and when it is determined according to the L1 measurement results that the L1 measurement reporting conditions are currently met, the terminal performs L1 measurement reporting.

[0171] The L3 measurement result of the neighboring cell is greater than the third set threshold, which can be understood as the value of the signal quality parameter represented by the L3 measurement result of the neighboring cell is greater than the third set threshold. The L3 measurement result of the neighboring cell is greater than the third set threshold including: the L3 measurement result of the neighboring cell is always greater than the third set threshold within the second set time, or the L3 measurement results of the neighboring cell corresponding to K consecutive times within the second set time are all greater than the third set threshold, or the L3 measurement results of the most recent K neighboring cells are all greater than the third set threshold, and K is a positive integer.

[0172] The L3 measurement result of the serving cell is less than the fourth set threshold, which can be understood as the value of the signal quality parameter represented by the L3 measurement result of the serving cell is less than the fourth set threshold. Among them, the layer 3 measurement result of the serving cell is less than the fourth set threshold includes: the L3 measurement result of the serving cell is always less than the fourth set threshold within the third set time, or the L3 measurement result of the serving cell is less than the fourth set threshold for H consecutive times within the third set time, or the L3 measurement result of the serving cell for the most recent H times is less than the fourth set threshold, and H is a positive integer.

[0173] The L3 measurement result satisfies the reporting event, which can be understood as the L3 measurement result satisfies any reporting event of A1 to A6, B1, and B2. In actual application, the L3 measurement result satisfies any reporting event of A3, A4, A5, A6, B1, and B2. For example, if the signal quality of the neighboring cell satisfying A3 is higher than the signal quality of the serving cell by a certain threshold (Neighbour becomes offsetbetter than SpCell), the relevant L1 measurement of the neighboring cell or the neighboring cell satisfying the A3 event is triggered. In an embodiment of the present application, the first condition includes the relevant conditions satisfied by the L3 measurement result, which can ensure the consistency of the effects of the L1 measurement and the L3 measurement.

[0174] If the moving distance of the terminal is greater than the set distance, it indicates that the terminal has moved far and needs to perform L1 measurement, so as to determine whether to perform cell change according to the L1 measurement result. The set distance can be determined based on the distance between the coverage areas of adjacent cells.

[0175] The first condition includes that when the terminal changes the cell group or changes the CU, the cell group may be a preconfigured or protocol-specified cell group. The cell group may be determined based on at least one of the following: geographically adjacent cells, multiple cells that the terminal will pass through due to terrain restrictions, and cells that the terminal passes through in a set route. The set route may include at least one of a high-speed rail route, a subway route, a light rail route, and a pedestrian street route.

[0176] It should be noted that, when the L1 measurement configuration represented by the second information includes a cell index or cell list or CU index or CU ID, the cell index or cell identifier associated with the same CU is in the same list, and one CU corresponds to one CU index. If the first condition includes that the terminal changes the CU, and the terminal switches to the new CU, then the terminal measures the cells in the cell list corresponding to the new CU, or measures the cells associated with the new CU. If the terminal does not switch the CU, the terminal performs one of the following: measures the cells in the cell list corresponding to the serving CU, measures the cells associated with the serving CU, does not measure the cells in the cell list corresponding to the CU, and does not measure the cells associated with other CUs.

[0177] It should be noted that, in the embodiment of the present application, the signal quality of the above-mentioned serving cell may be the maximum value of the signal quality parameter of the reference signal of the serving cell in the L1 measurement, for example, the maximum RSRP of the serving cell in the L1 measurement. The L3 measurement result of the neighboring cell may be the best L3 measurement result of the corresponding neighboring cell, for example, the maximum RSRP of the neighboring cell in the L3 measurement. Thus, unnecessary L1 measurements can be further reduced.

[0178] In order to reduce unnecessary L1 measurement reporting to reduce the measurement overhead and power consumption of the terminal, in one embodiment, the second condition includes at least one of the following:

[0179] The signal quality of the neighboring cell is higher than the signal quality of the serving cell by a fifth set threshold;

[0180] The signal quality of the neighboring cell is greater than or equal to the sixth set threshold;

[0181] The reduction value of the signal quality of the serving cell is greater than or equal to a seventh set threshold.

[0182] Here, the signal quality of the neighboring cell is higher than the signal quality of the serving cell by a fifth set threshold, which can be understood as: the difference between the value of the signal quality parameter of the neighboring cell and the value of the signal quality parameter of the serving cell is greater than the fifth set threshold. The signal quality of the neighboring cell is higher than the signal quality of the serving cell by a fifth set threshold including:

[0183] Within the fourth set time, the signal quality of the neighboring cell is always higher than the signal quality of the serving cell by a fifth set threshold, or the signal quality of the neighboring cell has been higher than the signal quality of the serving cell by the fifth set threshold for the most recent J times, where J is a positive integer.

[0184] The signal quality of the neighboring cell is greater than or equal to the sixth set threshold, which can be understood as the value of the signal quality parameter of the neighboring cell is greater than or equal to the sixth set threshold. Among them, the signal quality of the neighboring cell is greater than or equal to the sixth set threshold includes: the signal quality of the most recent G neighboring cells is greater than or equal to the sixth set threshold, and / or, the signal quality of the neighboring cell within the fifth set time is greater than or equal to the sixth set threshold; G is a positive integer. For example, in the most recent G measurement results, the RSRP of the neighboring cell is always greater than or equal to the first set threshold, or, within the fifth set time, the RSRP of the neighboring cell is greater than or equal to the first set threshold.

[0185] The decrease in the signal quality of the serving cell is greater than or equal to the seventh set threshold, which can be understood as a sudden drop in the signal quality of the serving cell in the L1 measurement or the L3 measurement. For example, the difference between the first RSRP of the serving cell and the second RSRP of the serving cell is greater than or equal to the seventh set threshold, the first RSRP is greater than the second RSRP, and the first RSRP is obtained after the second RSRP.

[0186] It should be noted that the signal quality of the neighboring cell in the second condition can be obtained by L1 measurement or L3 measurement, and the signal quality of the serving cell in the second condition can be obtained by L1 measurement or L3 measurement. The signal quality of the neighboring cell can be the maximum value of the signal quality parameter of the reference signal of the neighboring cell, and the signal quality of the serving cell can be the maximum value of the signal quality parameter of the reference signal of the serving cell, thereby further reducing unnecessary L1 measurements.

[0187] In order to reduce unnecessary L1 measurements, the network device may also instruct the terminal to start performing L1 measurements.

[0188] Based on this, in one embodiment, the method further includes:

[0189] Receive third information sent by the first network device, wherein the third information is used to instruct the terminal to start L1 measurement.

[0190] Here, the third information can be understood as indication information for starting L1 measurement. The third information can be carried in downlink control information (DCI), in a media access control layer (MAC) control element (CE), or in a physical downlink control channel (PDCCH) order for timing advance (TA) measurement.

For example, when the second information includes the index of the cell, the index of the beam, the cell or cell group to be measured, some or all cells carried by the DU can be determined by the second information. When the second information does not include the index of the cell, the index of the beam, the cell or cell group to be measured, L1 measurement can be performed on all cells carried by the DU.

[0207] Determining whether the L1 measurement result satisfies the second condition;

[0208] When the second condition is met, the L1 measurement report is reported to the first network device or not reported.

[0209] Here, the terminal can determine whether the second condition is currently met based on the value of the signal quality parameter included in the L1 measurement result; when the second condition is currently met and the second condition is a condition for triggering L1 measurement reporting, the terminal reports the L1 measurement report to the first network device based on the L1 measurement result that meets the second condition; when the second condition is currently met and the second condition is a condition for prohibiting L1 measurement reporting, the terminal does not report the L1 measurement report.

[0306] Step 3: The CU of the first network device sends an LTM switching request to the DU of the second network device.

[0307] Here, when the CU of the first network device decides to trigger the LTM, an LTM switching request is sent to the DU of the second network device.

[0308] The second network device can be understood as the network device to which the candidate cell belongs. The LTM handover request can be a terminal context modification request (UE CONTEXT MODIFICATION REQUEST).

[0310] Here, the DU of the second network device determines the L1 measurement configuration and / or the LTM configuration based on the LTM switching request, and returns an LTM switching response to the CU of the first network device.

[0311] The LTM switching response may be a terminal context modification response (UE CONTEXT MODIFICATION RESPONSE), which may carry L1 measurement configuration and / or LTM configuration; the LTM configuration may include LTM candidate cell configuration, and the LTM candidate cell configuration may be understood as the LTM configuration of the candidate cell.

[0312] Step 5: The CU of the first network device sends first information to the DU of the first network device.

[0313] Here, the first information may be carried in an RRC reconfiguration message, and the RRC reconfiguration message is included in a downlink RRC message transmission (DL RRC MESSAGE TRANSFER) message. The first information includes at least one of the following:

[0326] Arrive at the first time;

[0327] The first timer times out;

[0328] The L3 measurement result of the neighboring cell is greater than the third set threshold;

[0330] L3 measurement results meet the reporting event requirements;

[0331] The moving distance of the terminal is greater than the set distance;

[0332] The terminal changes the cell group or changes the CU.

[0333] In one embodiment, the second condition includes at least one of the following:

[0334] The signal quality of the neighboring cell is higher than the signal quality of the serving cell by a fifth set threshold;

[0335] The signal quality of the neighboring cell is greater than or equal to the sixth set threshold;

[0336] The reduction value of the signal quality of the serving cell is greater than or equal to a seventh set threshold.

[0337] Step 6: The DU of the first network device sends first information to the terminal.

[0338] Step 7: The terminal performs L1 measurement based on the first information to obtain an L1 measurement result.

[0339] Wherein, when the first condition is not met, the terminal does not perform L1 measurement.

[0340] Step 8: The terminal determines whether the L1 measurement result satisfies the second condition included in the first information.

[0341] Step 9: When the second condition is met, the terminal reports the L1 measurement report to the DU of the first network device.

[0342] Here, the L1 measurement report includes at least one of the following:

[0343] An index or index list of a first cell or a first cell group satisfying a second condition;

[0344] an index or a list of indices of relevant reference signals satisfying a second condition;

[0345] an index or a list of indices of relevant beams satisfying a second condition;

[0346] L1 measurement results;

[0347] The index of the LTM configuration.

[0348] Step 10: The DU of the first network device receives the L1 measurement report reported by the terminal, and sends seventh information to the CU of the first network device based on the L1 measurement report.

[0349] Here, the seventh information includes at least one of the following:

[0350] An index or index list of a first cell or a first cell group satisfying a second condition;

[0351] an index or a list of indices of relevant reference signals satisfying a second condition;

[0352] L1 measurement results;

[0353] Index of LTM configuration;

[0354] Information of the second DU, where the second DU represents the DU deploying the first cell or the first cell group.

[0355] Step 11: The CU of the first network device receives the first information, and sends a first message to the DU of the second network device based on the seventh information.

[0356] Here, the first message may be a UE CONTEXT MODIFICATION REQUEST, which is used to trigger or instruct the DU of the second network device to update related configurations. The first message carries at least one of the following:

[0357] Information about the second DU;

[0358] Information of the terminal performing L1 measurement;

[0359] An index or index list of a first cell or a first cell group that meets the second condition;

[0360] an index or an index list of relevant reference signals satisfying the second condition;

[0361] L1 measurement results;

[0362] The index of the LTM configuration.

[0363] The L1 measurement result may be the L1 measurement result of the first cell or the first cell group carried by the second DU of the second network device, or may be all L1 measurement results received by the CU of the first network device.

[0364] Step 12: The DU of the second network device returns a second message to the CU of the first network device based on the first message.

[0365] Here, upon receiving the first message, the DU of the second network device updates relevant configurations based on the information carried in the first message, for example, updating the LTM configuration, updating the terminal context, updating the preamble, updating the TCI status, updating the BWP ID, etc.

[0366] When the DU of the second network device updates the relevant configuration, it can return a second message to the CU of the first network device. The second message can be understood as a response to the first message. For example, the second message can be a UE CONTEXT MODIFICATION RESPONSE message. The second message is used to indicate that the DU of the second network device has updated the relevant configuration.

[0367] Step 13: The CU of the first network device sends an LTM cell switch command to the terminal through the DU of the first network device.

[0368] Step 14: The terminal receives the LTM switching command and executes LTM cell switching.

[0369] In this embodiment, since the first network device does not know the specific signal reception status of the terminal, the terminal independently decides whether to perform L1 measurement based on the first information, which can avoid the terminal performing unnecessary L1 measurement or starting measurement too late, which may cause handover failure.

[0370] Application Example 2: The first network device instructs the terminal to start L1 measurement

[0371] like Figure 6 As shown, Figure 6 The measurement method shown is relative to Figure 5 The measurement methods shown differ in that: Figure 6 Step 7 is added, and in step 8, the terminal can also perform L1 measurement based on the third information.

[0372] Step 7: The DU of the first network device sends third information to the terminal.

[0373] Here, when the DU of the first network device sends the third information to the terminal, the first information may not include the first condition.

[0374] The third information may include at least one of the following:

[0375] The fourth information includes at least one of the following: an index of a cell, an index list of a cell, an index of a cell group, an index of a beam, and an index of an LTM configuration;

[0376] fifth information, the fifth information including information of the first DU;

[0377] The sixth information represents information of the first CU.

[0378] Step 8: The terminal performs L1 measurement based on the third information, or performs L1 measurement based on the first information and the third information, to obtain an L1 measurement result.

[0379] Here, when the third information does not include the fourth information, or the third information does not include the fourth information, the fifth information, and the sixth information, the terminal performs L1 measurement on the cell or cell group to be measured contained in the first information. When the third information includes the fourth information, the terminal only needs to perform L1 measurement on the first cell, the first cell group, and the beam indicated by the third information, or perform L1 measurement according to the LTM configuration indicated by the third information.

[0380] In this embodiment, the first network device can determine the candidate cells or cell groups that need to perform L1 measurement, and send third information to the terminal to indicate that the terminal only needs to perform L1 measurement on the candidate cells or cell groups indicated by the third information, which can further reduce unnecessary L1 measurements and reduce the power consumption and measurement overhead of the terminal.
