Abstract

A method for indicating an uplink resource is provided, including that: when a base station side transmits an uplink resource indication signaling in a downlink subframe, an uplink subframe indication signaling corresponding to the uplink resource indication signaling being transmitted together; and the uplink subframe indication signaling is used for indicating an uplink subframe used by a user side to transmit data according to the uplink resource indication signaling. A system for implementing the method is also provided, which can distinguish a resource indication signaling corresponding to different uplink subframes in the same downlink subframe, and avoid that all the users of different uplink subframes transmit the data in the same resource of the same uplink frame, thereby avoiding mutual interference between the users of the uplink subframes, ensuring system performance and resulting in less signaling overhead.
