INTER-POINT DATA EXCHANGE IN UL COMP

摘要

A data exchange method in a CoMP system, an assistant point and a converging point. The method comprises steps of selecting a predetermined number of subbands with the best channel quality, and exchanging user data of the selected subbands. Only part of the user data received at the assistant point is transmitted to the converging point. The requirement on the transport network capacity is thus loosened. By transmitting data with the best channel quality, a good enough gain is guaranteed.
