PARTIALLY COHERENT TRANSMISSION FOR A MULTI-CARRIER COMMUNICATION SYSTEM

摘要

A method and apparatus for performing partially coherent Multiple Input Multiple Output (MIMO) transmissions within a multi-carrier communication system is provided herein. During operation similar information bits enter each base station (401, 402). The information bits are encoded (404) by each base station to produce a plurality of systematic bits and parity check bits. Each base station produces a set of similar systematic/parity bits and dissimilar systematic/parity bits. The similar bits are modulated and transmitted using the same resource elements. The remaining symbols are transmitted on any resource elements. Thus the transmissions from multiple base stations are received by the UE partially coherently. Since the same fractions of systematic bits are transmitted from each base station, the transmissions are homogeneous and hence can be received and decoded equally well in any cell area outside the handover region (i.e. closer to the base station).
