View Patent ↗The present disclosure provides a method executed by user equipment, the method comprising: receiving downlink control information (DCI), the DCI comprising a repetition number; determining a number of subframes required to transmit a physical uplink shared channel (PUSCH) (N) according to the repetition number, a number of allocated resource units, and time occupied by each resource unit; and transmitting the PUSCH in the determined N subframes. The time occupied by each resource unit is expressed by: a number of uplink slots occupied by each resource unit, or a number of uplink subframes occupied by each resource unit. In addition, the present disclosure further provides corresponding user equipment and a base station.
