摘要： Embodiments of the present invention provide a method and an apparatus for transmitting a physical uplink shared channel (PUSCH). The method comprises: determining a time-domain position for transmitting the PUSCH according to a downlink transmission time interval (TTI) for receiving a scheduling grant; and transmitting the PUSCH at the determined time-domain position, the scheduling grant comprising at least one of the following pieces of information: information indicating whether to transmit a demodulation reference signal (DMRS); information related to a first time-domain position for transmitting the DMRS; information related to a second time-domain position for transmitting data; information on a frequency-domain density of the DMRS; and information of a frequency-domain offset of the DMRS. By means of the embodiments of the present invention, a resource for transmitting a PUSCH can be effectively determined.
