Abstract
The present disclosure provides a PUSCH transmission method, a PUSCH reception method, a UE and a base station. The PUSCH transmission method includes: determining indication information about an HARQ-ACK, the indication information about the HARQ-ACK being at least used to indicate whether there is HARQ-ACK information on a target PUSCH; and transmitting the indication information on the target PUSCH. According to the present disclosure, the indication information about the HARQ-ACK is additionally transmitted by the UE on the PUSCH, and the indication information is at least used to indicate whether there is the HARQ-ACK information on the target PUSCH.
