The wireless communication system includes a terminal 11 and a network-side device 12.

The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings through some embodiments and application scenarios thereof.

As shown in fig. 2, a flowchart of a method 200 for beam failure detection provided in an exemplary embodiment of the present application is illustrated, where the method 200 may be, but is not limited to be, executed by a terminal, and in particular may be executed by hardware and/or software installed in the terminal. In this embodiment, the method 200 may include at least the following steps.

And S210, the terminal determines whether the BF event occurs or does not occur according to the first counter and/or the second counter.

In this embodiment, the terminal may measure a target reference signal used for beam failure detection in a physical layer, and determine whether a beam failure event occurs based on a measurement result, but considering that an unlicensed frequency band must meet regulatory regulations when being used to ensure that all devices may fairly share the resource, for example, a Listen Before Talk (LBT) Channel, a Maximum Channel Occupancy Time (MCOT), and the like. Taking LBT as an example, when a network side (such as a base station, etc.) needs to transmit information such as a target reference signal, LBT needs to be performed on a specified wireless channel first to perform Energy Detection (ED) on a surrounding wireless transmission environment, and when the Energy is higher than a certain threshold, it is determined that the transmission channel is busy and the network side cannot transmit. In this case, the channel quality measured by the terminal based on the target reference signal must not satisfy the transmission requirement, that is, the terminal may determine that the aforementioned designated wireless channel cannot provide reliable communication, and declare a beam failure. But no beam failure actually occurs at this time. In this regard, the first counter is introduced, and the beam failure is judged according to the first counter and/or the second counter, so that the accuracy of beam failure detection can be improved.

Based on this, in this embodiment, the first counter corresponds to a first threshold, and the first threshold is a threshold corresponding to LBT failure. Optionally, the first counter is a counter newly introduced in the present application, and is configured to count LBT failure times, in which case, the first counter may be disposed in a physical layer or a Medium Access Control (MAC) layer, that is, the first counter may be a physical layer counter or a MAC layer counter.

The second counter corresponds to a second threshold, and the second threshold is a threshold corresponding to the failure of beam reception; that is, the second counter is configured to count a beam failure instance (BFI, which may also be understood as beam failure information or beam failure indication), so that the terminal determines a beam failure event based on the second counter.

In one implementation, the first threshold may be greater than the second threshold, so that when the terminal performs counting on the first counter and/or the second counter based on the first threshold and the second threshold, the accuracy of the counting result may be improved, and thus the beam failure and the LBT failure may be more accurately distinguished.

It is to be understood that the first counter, the first threshold, the second counter, and the second threshold may be implemented by protocol convention, higher layer configuration, or network side configuration, and are not limited herein.

In this embodiment, the terminal determines that a BF event occurs or does not occur according to the first counter and/or the second counter, so that the problem of BFI false increase due to LBT failure can be effectively avoided, and the accuracy of beam failure detection is further improved.

As shown in fig. 3, a flowchart of a method 300 for beam failure detection provided in an exemplary embodiment of the present application is shown, where the method 300 may be, but is not limited to being, executed by a terminal, and in particular may be executed by hardware and/or software installed in the terminal. In this embodiment, the method 300 may include at least the following steps.

And S310, the terminal determines whether a BF event occurs or does not occur according to the first counter and/or the second counter.

The first counter corresponds to a first threshold, and the first threshold is a threshold corresponding to LBT failure; the second counter corresponds to a second threshold, and the second threshold is a threshold corresponding to a beam reception failure.

It is understood that the implementation of S310 has been described with reference to the method embodiment 200, and as a possible implementation manner, the manner in which the terminal determines that the BF event occurs or does not occur according to the first counter and/or the second counter may include at least one of the following (11) - (13).

(11) Determining that the BF event occurs in a case where a count value of the first counter is not less than a first predetermined value. That is, when the count value of the first counter reaches a first predetermined value, the terminal may default to a beam failure and start a flow of beam failure recovery.

For example, assuming that the count value of the first counter is a and the first predetermined value is a, if a > = a, it may be determined that the BF event has occurred.

Optionally, the counting process of the first counter includes: when the detected Block Error Rate (BLER) of the target reference signal is greater than the first threshold, the terminal increases the count value of the first counter, for example, the first counter increases by 1.

Wherein, the first counter is a MAC layer counter or a physical layer counter. That is, when the first counter is a MAC counter or a physical layer counter and the detected BLER of the target reference signal is greater than the first threshold, the count value of the first counter is incremented.

In addition, the target Reference Signal may include, but is not limited to, a Channel State Information Reference Signal (CSI-RS), a Synchronization Signal Block (SSB), or other BFD-RS, etc., and is not limited herein.

Optionally, the terminal reports an LBT failure indication to a MAC layer of the terminal when the detected BLER of the target reference signal is greater than the first threshold.

In one implementation, the terminal may determine that LBT fails, report an LBT failure indication to a MAC layer of the terminal, and increase a count value of the first counter when detecting that BLER of a target reference signal is greater than the first threshold.

(12) In a case where the sum of the count value of the first counter and the count value of the second counter is not less than a second predetermined value, it is determined that the BF event has occurred, and a flow of beam failure recovery may be started.

For example, assuming that the count value of the first counter is a, the count value of the second counter is B, and the second predetermined value is C, if a + B > = C, it may be determined that the BF event has occurred.

In this case, the counter of the first counter may refer to the relevant description in (11).

The counting process of the second counter may include at least one of the following (121) - (123).

(121) In case the detected BLER of the target reference signal is not greater than the first threshold but greater than the second threshold, the count value of the second counter is increased, e.g., the count value of the second counter is increased by 1.

(122) And when the first counter is a MAC layer counter and the count value of the first counter reaches a fifth preset value, the count value of the second counter is increased.

(123) And when the first counter is a physical layer counter and the count value of the first counter is not less than the fifth predetermined value, the count value of the second counter is increased.

(13) And under the condition that the count value of the first counter is not less than a third preset value and/or the count value of the second counter is not less than a fourth preset value, determining that the BF event occurs and starting the beam failure recovery process.

For example, assuming that the count value of the first counter is a, the count value of the second counter is B, the third predetermined value is a, and the fourth predetermined value is B, it may be determined that the BF event occurs if a > = a, or it may be determined that the BF event occurs if B > = B; alternatively, if a > = a, and B > = B, it may be determined that the BF event occurred.

It should be noted that the first predetermined value, the second predetermined value, the third predetermined value, the fourth predetermined value, the fifth predetermined value, etc. mentioned in this application may be implemented by protocol convention, higher layer configuration or network side configuration. In addition, the first predetermined value, the second predetermined value, the third predetermined value, the fourth predetermined value and the fifth predetermined value may be the same or different, and are not limited herein.

Of course, as a possible implementation manner, the terminal reports the beam failure instance BFI to the MAC layer and/or resets the first counter when determining that the BF event occurs.

For example, when the first counter is a physical layer counter and it is determined that a BF event occurs, the BFI is reported to the MAC layer, and the first counter is reset.

For another example, when the first counter is a MAC layer counter and it is determined that a BF event occurs, reporting of BFI to the MAC layer may be cancelled, but the first counter needs to be reset.

And S320, executing a preset operation.

Wherein the predetermined operation includes at least one of the following (21) - (24).

(21) The MAC layer of the terminal resets the first counter upon receiving an LBT failure indication.

(22) And the terminal resets the first counter under the condition that the first counter is overtime.

(23) And the MAC layer of the terminal resets the second counter under the condition of receiving BFI.

(24) And the terminal resets the second counter under the condition that the second counter is overtime.

It can be understood from the foregoing (21) - (24) that the first counter and the second counter may be independent counters or may be the same counter, which is not limited in this embodiment.

In addition, the term "reset" in the present embodiment may also be understood as restart, reset, recount, etc., and is not limited herein.

Based on the foregoing description of the method 200/300 for beam failure detection, the beam failure detection procedure given in this embodiment is further described below with reference to the following examples, which are as follows.

The terminal measures a target reference signal for beam failure detection in a physical layer, and judges whether a beam failure event occurs according to a measurement result of the target reference signal and the first counter and/or the second counter. Wherein the first counter corresponds to a first threshold, and the first threshold is a threshold corresponding to an LBT failure, and the second counter corresponds to a second threshold, and the second threshold is a threshold corresponding to a beam reception failure.

Based on this, if the BLER of the target reference signal measured by the terminal on the physical layer is greater than the first threshold, it may be determined that the BLER of the target reference signal measured by the terminal is greater than the first threshold due to LBT failure (that is, at a position where the target reference signal should be originally transmitted, since the monitored channel is busy, the network side does not transmit the target reference signal).

At this time, the terminal may start or reset the count value of the first counter. For example, when the first counter is a counter for the MAC layer at the MAC layer, the terminal may report an LBT indication to the MAC layer, and the count value of the first counter is incremented by 1; or, when the first counter counts in the physical layer, the count value of the first counter is increased by 1; when the LBTF _ Timer (a Timer indicated based on the LBT, corresponding to a beam Failure Recovery Timer) times out or is reconfigured, the first counter is reset to 0.

For another example, if the first COUNTER reaches a fifth predetermined value (the first COUNTER may be at the physical layer or the MAC layer), a BFI event occurs by default, and the second COUNTER (BFI _ COUNTER) +1 triggers a beam failure procedure when the second COUNTER reaches a certain value.

Alternatively, if the first counter reaches the first predetermined value, the beam failure is declared directly, the flow of beam failure recovery is triggered (normally declared at the MAC layer), and then the first counter is reset to 0.

Or, the terminal may combine the first COUNTER and the second COUNTER (BFI _ COUNTER), determine whether the beam fails, and trigger a beam failure recovery procedure. The aforementioned joint judgment may include at least one of the following (41) to (43).

(41) The sum of the two counters is equal to or larger than a certain value (such as A + B > = C).

(42) Both satisfy at the same time the respective fixed values (a > = a and (and) B > = B) or more.

(43) One of the two satisfies a predetermined value (A > = a or (or) B > = B) corresponding to the value (A > = a or (or) B >).

Finally, the first counter is reset to 0 in case it is determined that a beam failure occurred.

In this embodiment, a related process of determining a beam failure by the terminal in combination with the first counter and the second counter is further provided, so that the reliability of the beam failure detection result can be further improved.
