Abstract: Coordinate multi-point (CoMP) transmission is facilitated by resolving collisions between feedback reporting. Based upon the conditions within the network, collision resolution may be by dropping a channel report during a subframe, multiplexing channel reports from a plurality of user equipment, compressing channel reports from a plurality of user equipment, and combined reporting, either through joint reports or by using carrier aggregation, for conditions between a user equipment and a plurality of transmission points. New signaling and reporting formats facilitate selection of a collision resolution suitable for current network conditions.
