Subframe configuration method, base station and user equipment in time division duplex system

The embodiment of the invention discloses a subframe configuration method, base station and user equipment in a time division duplex system. The method comprises the following steps of: determining subframe numbers of flexible subframes in a radio frame by the base station; determining the attributes of the flexible subframes corresponding to the subframe numbers by the base station; representing that the flexible subframes are uplink subframes or downlink subframes through the attributes; and sending a first signal from the base station to the user equipment through a downlink control channel, wherein the first signal comprises the attributes of the flexible subframes corresponding to the subframe numbers. By adopting the method, the base station and the user equipment, disclosed by the embodiment of the invention, the purpose of notifying the user equipment of the situation that the certain flexible subframe is the uplink subframe or downlink subframe by the base station can be realized, and the user equipment can perform normal communication with the base station under the situation of knowing the attributes of the flexible subframes.
