Wireless communication apparatus for beam failure recovery
A wireless communication method and apparatus and a communication system. The wireless communication method includes: a terminal equipment receives an indication information set; and the terminal equipment determines a priority of a first uplink signal according to the indication information set, the first uplink signal being an uplink signal used for beam failure recovery.
1. A wireless communication apparatus, configured in a terminal equipment, the apparatus comprising:
a receiver configured to receive an indication information set;
processor circuitry configured to determine a priority of a first uplink signal according to the indication information set, the first uplink signal being an uplink signal used in performing beam failure recovery; and
a transmitter configured to transmit a third uplink signal, wherein information carried by the third uplink signal comprises information carried by the first uplink signal and information carried by a second uplink signal, and wherein a resource used in transmitting the first uplink signal overlaps a resource used in transmitting the second uplink signal, and the priority of the first uplink signal is identical to a priority of the second uplink signal.
2. The apparatus according to claim 1 , wherein the indication information set at least comprises indication information, the indication information indicating the priority of the first uplink signal, and the processor circuitry determines the priority of the first uplink signal according to the indication information.
3. The apparatus according to claim 1 , wherein the indication information set at least comprises indication information, the indication information indicating a priority of a beam failure recovery process and/or a configuration to which the first uplink signal corresponds, and the processor circuitry determines the priority of the first uplink signal according to the indication information.
4. The apparatus according to claim 1 , wherein the indication information set at least comprises indication information, the indication information indicating, or being used in determining at least one of the following priorities:
a priority to which activated Semi-Persistent Scheduling Physical Downlink Shared Channel (SPS PDSCH) reception corresponds;
a priority to which activated Configured Grant Physical Uplink Shared Channel (CG PUSCH) transmission corresponds; and
a priority associated with downlink control information;
and the processor circuitry determines the priority of the first uplink signal according to the indication information.
5. The apparatus according to claim 4 , wherein the processor circuitry determines the priority of the first uplink signal according to a highest priority in priorities to which the indication information corresponds.
6. The apparatus according to claim 4 , wherein the priority to which activated SPS PDSCH reception corresponds refers to a priority to which an SPS configuration corresponds, the activated SPS PDSCH reception corresponding to the SPS configuration.
7. The apparatus according to claim 4 , wherein the priority to which activated CG PUSCH transmission corresponds refers to a priority to which a CG configuration corresponds, the activated CG PUSCH transmission corresponding to the CG configuration.

a highest priority indicated by a field of the downlink control information indicating priorities;
a highest priority to which a scrambling ID corresponds, the scrambling ID scrambling CRS to which the downlink control information corresponds;
a highest priority to which a control resource set corresponds, a search space monitoring the downlink control information corresponding to the control resource set; and
a priority to which a format of the downlink control information corresponds.
9. The apparatus according to claim 1 , wherein indication information in the indication information set is applied to at least one cell corresponding to the first uplink signal.
10. The apparatus according to claim 1 , wherein:
the transmitter is further configured to transmit the first uplink signal, wherein the resource used in transmitting the first uplink signal overlaps the resource used in transmitting the second uplink signal, and the priority of the first uplink signal is identical to the priority of the second uplink signal.
