WIRELESS COMMUNICATIONS SYSTEM, BASE STATION, MOBILE STATION AND WIRELESS COMMUNICATIONS METHOD

摘要

The purpose of the invention is to provide a wireless communications system which, while achieving a reduction in intercellular interference to a downlink control channel of an interfered cell, is capable of decoding a downlink shared channel of an interfering cell. The wireless communications system controls the respective transmission timings of a first base station and a second base station such that the control channel transmitted by the first base station and the shared channel transmitted by the second base station temporally overlap. The second base station has a muting control unit (22) and a muting processing unit (29) which transmit a null symbol in a time block of the shared channel that overlaps with a time block of the control channel, on the basis of number of code blocks of a data signal component for each mobile station corresponding to the time block of the shared channel that overlaps with the time block of the control channel.
