Data transmission method and equipment for carrier aggregation system

Abstract

The embodiment of the invention discloses a data transmission method and data transmission equipment for a carrier aggregation system, and relates to the technical field of wireless communication. The method and the equipment are used for solving the problem of how to transmit data in a sub-frame with an uncertain uplink/downlink transmission direction by user equipment (UE). The method comprises that: a terminal determines whether uplink scheduling signaling for the sub-frame with the uncertain uplink/downlink transmission direction is received from a base station or not; and the terminal transmits uplink data or receives downlink data by using the sub-frame with the uncertain uplink/downlink transmission direction according to a determination result. The terminal in the scheme can determine how to transmit the data in the sub-frame with the uncertain uplink/downlink transmission direction according to whether the uplink scheduling signaling is received or not, thereby solving the problem of how to transmit the data in the sub-frame with the uncertain uplink/downlink transmission direction by the UE not supporting synchronous uplink and downlink transmission.
