Wherein, the target report is any one of the following: beam report, CSI report.

In related technologies, the UE can only report the RS measurement of the neighbor cell of the current serving cell on layer 3. Layer 3 reporting needs to perform layer 3 filtering on layer 1 measurement results, which has a large delay, and layer 3 reporting is a high-level behavior, and the delay itself is very long, resulting in a long delay for the UE to report measurement results.

However, in the embodiment of the present application, the UE can report the RS measurement of the neighbor cell of the current serving cell on layer 1, that is, the UE does not need to perform layer 3 filtering on the measurement result of layer 1, so that the delay can be reduced. In addition, layer 1 reporting is not a high-level behavior, so it can further reduce the time delay for the UE to report the measurement result.

In the measurement method provided in the embodiment of the present application, the UE can acquire measurement configuration information, perform layer 1 measurement on the RS of the target neighboring cell according to the measurement configuration information, and report the measurement result of the layer 1 measurement. When the UE obtains the measurement configuration information, it can directly perform layer 1 measurement on the RS of the target neighboring cell according to the measurement configuration information, so that the UE can directly report the measurement result of the layer 1 measurement, that is, directly report the measurement result of the layer 1 Report to the network-side device without filtering the measurement results of layer 1 at layer 3 and reporting at layer 3. Therefore, the delay in reporting the measurement results by the UE can be reduced. In this way, the time for the UE to perform cell handover can be reduced. delay.

The RSs of the target neighboring cells are all configured in the SMTC window;

The first information in the configuration information of the RS of the target neighboring cell is the same as the first information in the configuration information of the SMTC window by default;

The first information in the configuration information of the RS of the target neighboring cell matches the first information in the configuration information of the SMTC window;

The transmit powers of the RSs of the target neighboring cells are different, or are the same by default.

In this embodiment of the present application, the first information includes at least one of the following: a frequency domain position, a time domain position, and a period.

Further optionally, in the embodiment of the present application, the network side device may configure the RSs of the target neighboring cells in the SMTC window.

Further optionally, in this embodiment of the present application, the UE defaults that the first information in the RS configuration information of the target neighboring cell is the same as the first information in the SMTC window configuration information.

Further optionally, in this embodiment of the present application, the UE defaults that the first information in the RS configuration information of the target neighboring cell matches the first information in the SMTC window configuration information.

Further optionally, in this embodiment of the present application, the UE may set the transmit power of the RSs of the target neighboring cells to be the same by default.

Further optionally, in the embodiment of the present application, when the measurement configuration information includes the configuration information of the SMTC window, but does not include the relevant configuration information of the target neighboring cell, the UE determines the relevant configuration information of the target neighboring cell according to the preset default value , and search for and measure the default value of RS in the STMC window. Wherein, the period of the RS of the target neighboring cell is the period of the SMTC window, and the UE defaults that the transmit power of the RS of each neighboring cell in the target neighboring cell is the same.

Further optionally, in this embodiment of the present application, in the case where the measurement configuration information includes the configuration information of the target neighboring cell and the configuration information of the SMTC window, if the RSs of the target neighboring cell are all configured in the SMTC window, the UE may Relevant configuration information of the target neighboring cell is received and measured on the corresponding time-frequency resource. Wherein, the RSs of the target neighboring cell are all configured in the SMTC window means: the period of the RS of the target neighboring cell is an integer multiple of the period of the SMTC window, and the first symbol of each RS is later than the first symbol of the SMTC window. symbols, the last symbol of each RS is earlier than the last symbol of the SMTC window.

Further optionally, in this embodiment of the present application, in the case where the measurement configuration information includes related configuration information of the target neighboring cell and configuration information of the SMTC window, if the RSs of some neighboring cells of the target neighboring cell are outside the SMTC window, the UE may According to the relevant configuration information of the target neighboring cell, only the RS included in the SMTC is received and measured on the corresponding time-frequency resource.

Optionally, in this embodiment of the present application, if the first condition is met, the layer 1 measurement value of the RS is: the layer 1 measurement value processed according to the first preset rule.

Optionally, in this embodiment of the present application, the above first condition is: the target neighboring cell includes multiple neighboring cells, and RSs of different neighboring cells among the multiple neighboring cells have different transmit powers.

Further optionally, in the embodiment of the present application, the above-mentioned first preset rule may specifically be: a rule according to a specific value of the alignment target.

It can be understood that the UE may amplify or reduce the layer 1 measurement values of the RSs of multiple neighboring cells according to the rule of aligning target specific values.

Specifically, the above specific target value may specifically be: a preset specific value, or a specific value determined according to layer 1 measurement values of RSs of multiple neighboring cells.

Exemplarily, assuming that multiple neighboring cells include cells Cell#1, Cell#2, and Cell#3, the layer 1 measurement value of Cell#1 is 2, the layer 1 measurement value of Cell#2 is 3, and the layer 1 measurement value of Cell#3 is The measured value of layer 1 is 1, and the intermediate value 2 of the measured values of layer 1 of all Cells is taken as the target specific value, then the measured value of layer 1 of Cell#1 after processing is 2, and the measured value of layer 1 of Cell#2 after processing is 2/3, and the layer 1 measurement value of Cell#3 after processing is 2.

It can be seen that since the UE can process the layer 1 measurement value of the RS of the target neighboring cell when the first condition is satisfied, it can avoid the situation that the layer 1 measurement value is inaccurate due to the difference in the transmission power of the RS .

Optionally, in this embodiment of the present application, referring to FIG. 2 , as shown in FIG. 3 , the measurement method provided in this embodiment of the present application may also The following

steps

It can be understood that the execution sequence of step 201 is after the "measurement of layer 1 on the RS of the target neighboring cell" in step 102 and before the "report of the measurement result of layer 1 measurement" in step 102.

Further optionally, in this embodiment of the present application, the content reported above includes at least one of the following: an index of the first RS, a layer 1 measurement value of the first RS, and a PCI of a neighboring cell to which the first RS belongs.

Further optionally, in this embodiment of the present application, the at least one first RS may specifically be: an RS among RSs of a target neighboring cell.

Further optionally, in the embodiment of the present application, the above-mentioned second preset rule may specifically be: select the RS corresponding to the first a measured values sorted from large to small, and a is a positive integer.

Exemplarily, assuming that multiple adjacent cells include cells Cell#1, Cell#2, Cell#3, Cell#4, and Cell#5, the layer 1 measurement value of Cell#1 is 2, and the layer 1 measurement value of Cell#2 is The value is 3, the layer 1 measurement value of Cell#3 is 4, the layer 1 measurement value of Cell#4 is 5, and the layer 1 measurement value of Cell#5 is 1, then the UE can be sorted according to the selected measurement value from large to small The RSs corresponding to the previous a (for example, the first 3) measurement values determine at least one first RS, that is, three first RSs: the RS of Cell#4, the RS of Cell#4 and the RS of Cell#2.

In step 202, the UE reports the measurement result of layer 1 measurement.

In the embodiment of the present application, the above-mentioned measurement result of layer 1 measurement includes: related information of at least one first RS.

It can be understood that the measurement result of layer 1 measurement includes at least one of the index of the first RS, the layer 1 measurement value of the first RS, and the PCI of the neighboring cell to which the first RS belongs.

It can be seen that, since the UE can determine at least one first RS from the RSs of the target neighboring cell according to the second preset rule, and report the index of each first RS in the at least one first RS, at least one first RS The layer 1 measurement value of each first RS in the RS, the PCI of the neighboring cell to which each first RS in at least one first RS belongs, instead of reporting the RS of the target neighboring cell, so the reported data can be reduced quantity.
