An embodiment of the present disclosure provides a method of measuring a reference signal. Figure 2 is a flow chart of a method of measuring a reference signal according to an exemplary embodiment. As shown in Figure 2, the method includes steps S201 to S203. specific:

Step S201: The network device sends configuration information to the user equipment, where the configuration information is used to configure the candidate turn-off reference signal and the turn-off period corresponding to the candidate turn-off reference signal.

After receiving the configuration information, the user equipment can learn that the reference signal is configured as a candidate for turning off and the corresponding turning off period, and that the network device does not send the corresponding reference signal during the turning off period.

Step S202: In response to the reference signal to be tested, at least one of the candidate turnable reference signals configured for the network device is determined according to the first measurement window of the reference signal to be tested and the turn-off period of the reference signal to be tested. signal measurement results.

In this method, when the reference signal to be tested is a candidate switchable reference signal configured by the network device, the shutdown period of the reference signal to be tested is taken into consideration when selecting the measurement sampling point, so as to avoid the shutdown period of the reference signal to be tested. Inaccurate measurement data affects the final measurement results. .

Embodiments of the present disclosure provide a method for measuring a reference signal, which is executed by user equipment. Figure 3 is a flow chart of a method for measuring a reference signal according to an exemplary embodiment. As shown in Figure 3, the method includes Steps S301~S302, specifically:

Step S301: In response to the reference signal to be tested being at least one of the candidate turnable reference signals configured for the network device, a measurement sampling point is determined based on the first measurement window of the reference signal to be measured and the turn-off period of the reference signal to be measured.

In some possible implementations, a method for determining a measurement sampling point based on a first measurement window of a reference signal to be measured and a shutdown period of the reference signal to be measured includes: determining that the measurement sampling point is: Measurement sampling points covered by the first measurement window of the reference signal and not covered by the shutdown period. Therefore, when selecting the measurement sampling points, the measurement sampling points in the off period of the reference signal to be measured are excluded, so as to avoid inaccurate measurement data in the off period of the reference signal to be measured and affecting the final measurement result.

Step S302: Determine the measurement result of the reference signal to be measured according to the determined measurement sampling point.

In a possible implementation, there are no measurement sampling points covered by the first measurement window of the reference signal to be measured and not covered by the closing period. The corresponding situation is: the first measurement window is closed by the period. Complete coverage means that the period of the first measurement window completely coincides with the closing period, or the period of the first measurement window is part of the closing period. This means that there is no need to measure the measurement sampling points in the first measurement window, and therefore it is not necessary to obtain the measurement results of the reference signal to be measured in the first measurement window.

In response to the reference signal to be measured including at least one of a first type reference signal, a second type reference signal and a third type reference signal, and there is no measurement window covered by the first measurement window of the reference signal to be measured. And the measurement sampling points that are not covered by the shutdown period are determined not to obtain or consider the measurement results of the reference signal to be measured within the first measurement window, so that the reporting timing corresponding to the first measurement window is No measurement results will be reported during this period.

In response to the reference signal to be measured being a fourth type reference signal, and there being no measurement sampling points covered by the first measurement window of the reference signal to be measured and not covered by the off period, determining the The measurement result of the reference signal to be measured within the first measurement window is the lowest quantized value of L1-RSRP or L1-SINR.

In an example, the lowest quantized value of L1-RSRP is -140dBm, and the lowest quantized value of L1-SINR is -23dB.

Figure 4 is a flow chart of a method for measuring a reference signal according to an exemplary embodiment. As shown in Figure 4, the method includes Step S401, specifically:

Step S401: In response to the reference signal to be tested, at least one of the candidate turnable reference signals configured for the network device is determined according to the first measurement window of the reference signal to be tested and the turn-off period of the reference signal to be tested. signal measurement results.

In some possible implementations, step S401 includes:

S401-1, in response to the reference signal to be measured including at least one of the first type of reference signal, the second type of reference signal, the third type of reference signal or the fourth type of reference signal, and there is simultaneously the third type of reference signal. A measurement window and a measurement sampling point covered by the closing period are determined to determine the measurement results of the measurement sampling points covered by both the first measurement window and the closing period as the set value.

S401-2: According to the set value and the measurement results of the measurement sampling points covered by the first measurement window of the reference signal to be measured and not covered by the off period, determine whether the reference signal to be measured is measurement results.

In an example, the setting value is determined according to the type of the reference signal to be measured, including the following two situations:

First, in response to the reference signal to be measured being a first type reference signal, a second type reference signal or a third type reference signal, the setting value is a value of a setting parameter configured by the network device.

When the reference signal to be measured is a first-type reference signal or a second-type reference signal, the setting value is the value of the setting parameter configured by the network device, that is, the value of BLER-in in the rlmInSyncOutOfSyncThreshold parameter, to indicate that the user equipment considers it to be The measurement sampling points covered by the first measurement window and the closing period can meet the requirements of in-sync.

When the reference signal to be measured is the third type of reference signal, the setting value is the value of the setting parameter configured by the network device, that is, the value of the rsrp-thresholdSSB parameter, to indicate that the user equipment considers it to be covered by the first measurement window and the shutdown period at the same time. The measurement sampling points can meet the in-sync requirements.

Second, in response to the reference signal to be measured being the fourth type of reference signal, the set value is the measurement average value in historical reporting opportunities of the reporting opportunities corresponding to the first measurement window.

Step S501: In response to the reference signal to be tested being at least one of the candidate closeable reference signals configured by the network device, determine the second measurement window of the reference signal to be tested according to the first measurement window of the reference signal to be tested;

Step S502: Determine the measurement result of the reference signal to be measured according to the second measurement window and the shutdown period.

In some possible implementations, it is determined that the second measurement window is composed of the first measurement window plus a set time length; wherein the first measurement window is when the reference signal to be measured is not configured as a candidate closeable reference signal. corresponding measurement window.

In an example, the first measurement window is marked as T1, the second measurement window is marked as T2, and the linear scaling parameter is 0.5, then T2=0.5T1. Among them, the linear proportional parameter is configured by the network device or agreed by the protocol.

In an example, the maximum off duration of the beam is T-off, then the second measurement window T2 is: T2=T-off.

In some possible implementations, determining the measurement result of the reference signal under test based on the second measurement window of the reference signal under test and the off period of the reference signal under test includes:

In a possible implementation, there are no measurement sampling points covered by the second measurement window of the reference signal to be measured and not covered by the closing period. The corresponding situation is: the second measurement window is closed by the period. Complete coverage means that the period of the second measurement window completely coincides with the closing period, or the period of the second measurement window is part of the closing period. This means that there is no need to measure the measurement sampling points in the second measurement window, and therefore it is not necessary to obtain the measurement results of the reference signal to be measured in the second measurement window.

In response to the reference signal to be measured including at least one of a first type reference signal, a second type reference signal and a third type reference signal, and there is no second measurement window covered by the reference signal to be measured. And the measurement sampling points that are not covered by the closed period are determined not to obtain the measurement results of the reference signal to be measured in the second measurement window, so that they are not reported within the reporting opportunity corresponding to the second measurement window. any measurement results.

In response to the reference signal to be measured being a fourth type reference signal, and there being no measurement sampling points covered by the second measurement window of the reference signal to be measured and not covered by the off period, determining the The measurement result of the reference signal to be measured within the second measurement window is the lowest quantized value of L1-RSRP or L1-SINR.

In the embodiment of the present disclosure, when the reference signal to be measured is at least one of the candidate turnable reference signals configured by the network device, the length of the corresponding measurement window is expanded so that there are as many unused signals as possible within the expanded measurement period. The measurement sampling points covered by the shutdown period prevent the measurement from being affected by the shutdown period.
