Method for transmission control and user equipment

A method for transmission control and user equipment, the method comprises: in a time division duplex system, when uplink component carrier aggregation and downlink component carrier aggregation are present on a subframe, the user equipment selects the subframe type of the subframe according to a predefined rule, and sends uplink information on the uplink component carrier of the subframe or receives downlink information on the downlink component carrier of the subframe according to the selected subframe type, wherein the subframe type comprises uplink subframe or downlink subframe, and the uplink information comprises uplink channel and/or uplink signal, the downlink information comprises downlink channel and/or downlink signal. By using the above technical solution, the mixed subframe is determined to be the uplink subframe or the downlink subframe, data is sent or received on the corresponding uplink component carrier or the downlink component carrier, consequently the aim of improving spectrum efficiency is achieved.
