1. An uplink transmission apparatus, configured in a terminal equipment, the apparatus including:
a memory that stores a plurality of instructions,
a receiver coupled to the memory and configured to receive first indication information indicating an uplink resource, and receive second indication information indicating the terminal equipment to transmit an uplink transmission when all bandwidth units of an uplink bandwidth part (UL BWP) are detected as being idle;
processor circuitry coupled to the memory and configured to perform channel detection on all bandwidth units of an uplink bandwidth part (UL BWP) including the uplink resource; and
a transmitter coupled to the memory and configured to transmit an uplink transmission on the uplink resource in the UL BWP when all bandwidth units of the UL BWP are detected as being idle,
wherein after a first bandwidth unit is selected, by the terminal equipment, from the bandwidth units in the UL BWP, channel detection based on random back-off is performed on the first bandwidth unit.
