Claim:
1. A method for coordinating one or more downlink transmissions in a wireless communication system comprising a cluster of base station clients in communication with a base station cluster coordinator, the method comprising: receiving at the base station cluster coordinator from each one of the cluster of base station clients, a User Equipment (UE) parameter set for each UE served by the respective one of the cluster of base station clients; determining a plurality of cluster parameter sets in respect of respective ones of a plurality of transmission modes at the base station cluster coordinator, based on the UE parameter sets; evaluating the cluster parameter sets at the base station cluster coordinator, in order to select at least one of the transmission modes for the cluster of base station clients; generating at the base station cluster coordinator at least one output according to the at least one transmission mode; and transmitting each output to at least one of the base station clients to control the at least one base station client to perform the one or more downlink transmissions, wherein a first one of the plurality of transmission modes is a transmission mode where only one of the cluster of base station clients performs a downlink transmission, wherein a second one of the plurality of transmission modes is a Coordinated Multi-Point (CoMP) transmission mode where each one of a set of the cluster of base station clients performs a downlink transmission, and wherein the CoMP transmission mode is selected from the group consisting of: a CoMP Coordinated Scheduling (CS) transmission mode where each one of the set of base station clients performs a downlink transmission to a respective one of a plurality of different UEs; a CoMP Joint Processing (JP) transmission mode where each one of the set of base station clients performs a downlink transmission to the same UE; and a CoMP hybrid transmission mode where each one of a first set of the cluster of base station clients performs a downlink transmission to the same UE, and each one of a second set of the cluster of base station clients performs a downlink transmission to a respective one of a plurality of different UEs.
