DYNAMIC MULTI-CELL CLUSTERING FOR DOWNLINK COMP IN A WIRELESS COMMUNICATION NETWORK

摘要

A method for generating at least one downlink CoMP cooperating set for downlink CoMP processing at a first node of a plurality of nodes in a network is provided. Each of the plurality of nodes managing at least one cell. A plurality of multi-dimensional UE points is determined. Each dimension of a respective multi- dimensional UE point corresponds to a channel quality metric value associated with a downlink signal received by the UE from a corresponding cell. At least one k- dimensional UE constellation is determined. Each k-dimensional UE constellation includes a set of UEs receiving downlink signals from k cells. At least one k- dimensional UE group is determined based on the determined at least one k- dimensional UE constellation. Each k-dimensional UE group is associated with the same cells. At least one downlink CoMP coordinating set is generated based on the plurality of k-dimensional UE groups.
