Specifically, the terminal may determine whether a second event occurs based on the number of received first events and/or the frequency of occurrence, and the like. The third condition may be related to the number and/or frequency at which the first event occurred. If the third condition is satisfied, the link quality corresponding to the signal in the first signal set is poor.

For example, if the number of consecutive first occurrences (which may occur continuously in a particular time) exceeds a certain value, then a second event may occur, that is, a beam failure may be said to have occurred.

Optionally, after determining that the second event occurs, the terminal may start a timer and perform a link reconfiguration procedure within a duration of the timer.

Less than or equal to can be understood as the following three cases: less than, equal to, and less than or equal to.

The following description will be combined with a few examples.

First, suppose q0 is a signal set containing one or more signals (which may be CSI-RS signals or SS/PBCH blocks). The terminal can measure the quality of the signals in the signal set to determine whether beam will occur. Failure instance (where the judgment threshold can be a Hypothetical Block Error Ratio (BLER). If the performance of all signals in q0 is worse than the threshold, then one beam failure instance is considered.

The terminal measures the link quality corresponding to the signal in q0 at the lower layer, and notifies the upper layer if the link quality is worse than the corresponding threshold. The upper layer determines, according to the lower layer notification, that if beam failure is sent (for example, N notifications are continuously received, the link quality is notified to be lower than the corresponding threshold); the upper layer continues the subsequent process:

Turning on a timer for controlling a beam failure recovery procedure (also referred to as a path reconfiguration procedure);

Notifying the lower layer to report one or more signals in the q1 that meet the threshold;

Sending a beam failure request to the network side;

Detecting the response of the network side feedback in the specified window

At the same time, the lower layer continues to measure and report the signal in q0, and the upper layer continues to judge according to the reported notification information. If it is judged that the current link re-enters a good state, the terminal cancels the continuation of the above process.

How to judge the current link re-entering a good state, a few examples are given below.

Example 1:

After the terminal determines that the beam failure occurs (that is, it determines that the current link quality is poor), the terminal works according to the process of beam failure judgment within a time range, and makes X judgments of the occurrence of beam failure, if X is less than or less than or equal to a certain The threshold (this threshold may be preset on the terminal or configured by the network), the terminal determines that the current link re-enters a good state.

The implementation of the foregoing time range may be implemented by using a timer or by other methods. The time range may be preset on the terminal or configured by the network.

Example 2:

There is only one time range in the first embodiment. In the example 2, on the basis of the example 1, in the continuous K time ranges, if the X is less than or equal to a certain threshold, the terminal judges that the current link re-enters. Better state.

Example 3:

After the terminal determines that the beam failure occurs (that is, the current link quality is poor), the total number of beam failure instances X is less than or equal to a certain threshold within a time range (this threshold may be a protocol, or a network configuration). Then, the UE judges that the current link re-enters a good state. This threshold can be zero.

The implementation of the foregoing time range may use a timer, or may be implemented by other methods; the time range may be preset on the terminal, or network configuration.

Example 4:

In the third embodiment, there is only one time range. In the example 4, on the basis of the example 3, in consecutive K time ranges, if X is less than or equal to a certain threshold, the UE determines that the current link re-enters. Better state.

Example 5:

After the terminal determines that the beam failure occurs (that is, determines that the current link quality is poor), the ratio between the total number of received beam failure instances and the non-beam failure instance is less than or equal to a certain threshold within a time range (this threshold) The terminal may be preset on the terminal, or the network configuration, and the terminal determines that the current link re-enters a good state. According to the received ratio of the total number of occurrences of the beam failure instance and the occurrence of the beam failure instance being greater than or equal to a certain threshold (this threshold may be preset on the terminal, or network configuration), the terminal determines the current link re-review Enter a better state.

The implementation of the foregoing time range may use a timer, or may be implemented by other methods. The time range may be preset on the terminal or network configuration.

Example 6

In the embodiment 5, there is only one time range. In the example 6, on the basis of the example 5, in the continuous K time ranges, if the ratio satisfies the corresponding condition, the terminal judges that the current link re-enters better. status.

Example 7:

After the UE determines that the beam failure occurs (that is, it determines that the current link quality is poor), it determines whether the beam failure is performed according to the low-level report in a time range; if no beam failure occurs in the consecutive K time ranges, the UE determines the current link. Re-enter the better state. K can be preset on the terminal, or network configuration. Each time range can be implemented using a timer, which can be preset on the terminal or configured by the network.

Optionally, in a case where it is determined that the quality of the signal in the first signal set is superior to the second condition, the terminal suspends the link reconfiguration procedure triggered by the previous second event, and/or stops the link. The timer that reconfigures the program.

Optionally, if it is determined that the quality of the signal in the first signal set is not superior to the second condition, the terminal continues to perform the link reconfiguration procedure triggered by the previous second event, and/or continues The timer of the link reconfiguration procedure.

Optionally, if it is determined that the quality of the signal in the first signal set is superior to the second condition, the terminal continues to perform detection of the PDCCH on the first control resource set, where the first control resource set is A resource set for detecting a PDCCH before the second event occurs.

If it is determined that the link quality corresponding to the signal in the first signal set is superior to the second condition, the terminal continues to perform PDCCH detection on the first control resource set, meaning that the terminal may have stopped before this. The PDCCH is detected on the first control resource set, or the PDCCH is always detected on the first control resource set.

The network side transmits the PDCCH by using a transmit beam of a signal in the first signal set reported by the terminal on the first control resource set.

Optionally, the terminal continues to perform detection of the PDCCH on the first control resource set before the first time, and/or stops detecting the PDCCH performed on the first control resource set after the first time;

Or, when the first protocol layer reports a signal to the second protocol layer, the signal is that the quality of the signal in the second signal set is superior to the signal satisfying the fourth condition;

Or, the moment of transmitting the first message to the network side, where the first message is used to indicate the selected at least one signal;

Or, starting to monitor the time when the network side responds to the second message sent by the first message; or,

Optionally, the conflict between the first control resource set and the detection of the second control resource set means that the terminal needs to detect the two resource sets at the same time, and the terminal is caused by the processing capability of the terminal or the direction of the receiving beam is different. These two resource sets are detected simultaneously.

Therefore, in the embodiment of the present application, in the case that it is determined that the second event occurs based on the occurrence of the first event, the terminal continues to determine the signal quality of the first signal set, and determines the signal in the first signal set. Whether the quality is excellent enough to satisfy the second condition, thereby improving the performance of beam failure recovery.
