Abstract:
1. A method for setting a Coordinated Multi-Point (CoMP) set of a serving enhanced Node B (eNB) in a wireless communication system, the method comprising: receiving first associated information between neighbor eNBs and User Equipments (UEs) from the UEs; selecting one or more neighbor eNBs from among the neighbor eNBs as a CoMP set based on the first associated information; receiving precoding matrix indices corresponding respectively to the selected neighbor eNBs from the UEs; receiving second associated information between the selected neighbor eNBs and the UEs from the UEs at irregular intervals; selecting one or more precoding matrix indices from among the received precoding matrix indices according to a preset condition and generating a precoding matrix index list including the selected precoding matrix indices and obtaining an average value of the first associated information and the second associated information of a corresponding neighbor eNB, wherein the preset condition indicates that reception frequencies are equal to or greater than a threshold; and
