A method and apparatus, a base station and user equipment for reducing interference in a wireless communication system are provide in the present invention. The wireless communication system comprises a first cell and a second cell, wherein uplink/downlink sub-frame configuration of the first cell and the second cell is asymmetry and may result in implementing a first type of sub-frame at the first cell while implementing a second type of sub-frame different from the first type of sub-frame at the second cell, thereby producing inter-cell interference. The method comprises: mapping a resource grid of at least one of the type of sub-frame and the second type of sub-frame to reserve at least one of a resource element in the first type of sub-frame and corresponding to a resource element in the second type of sub-frame and mapped for at least one of a reference signal and a common control channel, and a resource element in the second type of sub-frame and corresponding to a resource element in the first type of sub-frame and mapped for at least one of a reference signal and a common control channel, for not transmitting information; and transmitting a mapping result of the mapping step. |
