Abstract

The application discloses a physical uplink shared channel data transmission method and device. The method comprises: a terminal adjusts or schedules, according to detected downlink control channel data utilizing an uplink DCI format and/or PHICH data in a subframe n, PUSCH data to be transmitted in a special subframe (n+k), wherein k is a predefined value. A base station transmits the downlink control channel data utilizing the uplink DCI format and/or the PHICH data in the subframe n, to adjust or schedule the terminal to transmit the PUSCH data in the special subframe (n+k), wherein k is a predefined value. The application provides a schedule timing definition for transmitting PUSCH data in a special subframe, thereby ensuring normal transmission of the PUSCH data in the special subframe.
