A base station retransmits data to a user equipment (UE) using a fast beam selection process before the retransmission. The UE transmits an uplink feedback in a beam sweep manner to facilitate fast beam selection in retransmission. The base station can measure the beam sweep patterns from the UE to decide the best beam for retransmission. The UE can send a negative acknowledgment (NACK) or a reference signal in a beam sweep manner to facilitate beam selection at the base station for retransmission.

Provided are an uplink transmission method and device, a communication node and a storage medium. The uplink transmission method includes: cancelling a transmission of part or all of time domain symbols in a first uplink transmission in a case where the first uplink transmission overlaps with a second uplink transmission in a time domain, where the first uplink transmission corresponds to a first priority, the second uplink transmission corresponds to a second priority, and the first priority is lower than the second priority; and transmitting a third uplink transmission through time domain symbols of which the transmission is cancelled in the first uplink transmission in a case where a set condition is satisfied.

Described are embodiments for uplink beam reporting. A wireless device determines an overlap in time between: a first uplink channel resource of a permissible exposure report for a cell and a second uplink channel resource of a channel state information (CSI) report for the cell. Based on the determined overlap in time, the wireless device drops the CSI report scheduled for transmission via the second uplink channel resource, and transmits the permissible exposure report via the first uplink channel resource.
