Provided are a PUSCH method, user equipment and base station, the method comprising: receiving control signaling transmitted by a base station in a current sub-frame, the control signaling being used to instruct transmission of a PUSCH; according to the location of the current sub-frame, determining uplink resources used for transmitting the PUSCH, the uplink resources comprising UpPTS; transmitting the PUSCH over the uplink resources. In an embodiment of the present invention, the UpPTS is used for PUSCH transmission, equivalent to increasing the data volume in uplink transmission in unit time, thus increasing the uplink throughput of a TDD system.
