Abstract:
1. For use in a wireless communication network, a first base station configured to perform a coordinated multipoint transmission to a plurality of subscriber stations, the first base station comprising: a plurality of antennas configured to transmit data and control information; a transmitter coupled to the plurality of antennas, the transmitter configured to transmit a plurality of symbols in a sub-frame; and a controller comprising processing circuitry configured to use a scrambling sequence for a physical downlink shared channel (PDSCH) that is the same as used by a second base station functioning as an anchor cell and performing coordinated multipoint transmission with the first base station, and to synchronize the transmission of the plurality of symbols by puncturing PDSCH symbols assigned to a first portion of a PDSCH of the first base station, the first portion corresponding to a second portion of a PDSCH of the second base station, the second portion overlapping with a control region of the first base station when the first base station has a control region size greater than a control region size in the second base station.
