technical field
[0001]
This application relates to the field of communications.
Background technique
[0002]
Currently, in an NR (New Radio, new radio) system, only a primary cell (PCell) or a primary and secondary cell (PSCell) is supported to initiate a beam failure recovery procedure (beam failure recovery procedure). If a beam failure occurs on the secondary cell (SCell), the terminal device cannot timely notify the network device to make corresponding adjustments. However, since the SCell may carry a large amount of data services, the lack of beam failure resolution of the SCell will cause a sharp drop in system performance. Therefore, it is necessary to introduce a mechanism for solving the SCell beam failure, that is, the SCell beam failure procedure.
[0003]
In addition, the NR system will be further enhanced to enable simultaneous transmission of different types of services. In order to avoid conflicts between different services, a very important method is to indicate the corresponding priority to the signal, that is, the behavior of the terminal device when two signals collide can be judged by the priority corresponding to the corresponding signal.
[0004]

It should not be assumed that the above-mentioned technical solutions are known to those skilled in the art simply because these solutions are described in the background section of this application.

The cell corresponding to the BFR configuration or process, for example, the cell may be an SCell or a SpCell, and the cell may belong to the same cell group as the above-mentioned first uplink signal, which the present application is not limited to. Since the above-mentioned first uplink signal is associated with the above-mentioned cell, the indication information acting on the above-mentioned cell can help the terminal device to determine the priority of the first uplink signal. In addition, it can also be understood that if the indication information does not act on the cell, it is irrelevant to the priority of the first uplink signal. Thus, the terminal device can determine the priority of the first uplink signal according to the associated indication information.
[0061]
In this embodiment of the present application, the indication information in the foregoing indication information set may act on the activated bandwidth unit (BWP). Since the above-mentioned first uplink signal is associated with the above-mentioned BWP, the indication information acting on the above-mentioned BWP can help the terminal device to determine the priority of the first uplink signal.

[0068]
In at least one embodiment, if there is an activated UL CG, the terminal device may determine the priority of the first uplink signal at least according to the priority corresponding to the PUSCH transmission of the activated CG.

[0073]
For another example, DCI format 0_0/0_1/1_0/1_1 corresponds to the first priority; DCI format A corresponds to the second priority; wherein the second priority is higher than the first priority, then the DCI is associated with the highest priority The priority is the second priority.
[0074]
For another example, if DCI can only indicate one priority, then DCI format 0_0/0_1/1_0/1_1 corresponds to the first priority; if DCI can only indicate one priority, then DCI format A corresponds to the second priority ; wherein the second priority is higher than the first priority, then the highest priority associated with the DCI is the second priority.
[0075]

[0077]
In the above example, "the DCI can only indicate one priority" means that the DCI does not have a field for indicating the priority, or the DCI does not use the scrambled RNTI corresponding to the CRC to distinguish priorities, or the DCI The CORESET corresponding to the corresponding search space (SS) is not used for prioritization.
[0078]
