UE-centric clustering and efficient scheduling for CoMP

Abstract:

Certain aspects of the present disclosure provide techniques for user equipment (UE)-centric clustering and efficient scheduling for coordinated multipoint (CoMP). A method for UE-centric clustering and central scheduling includes determining a UE conflict graph. Vertices in the UE conflict graph are UEs for which there is a transmission and edges between vertices are UEs that have a scheduling conflict. The method includes transmitting signaling to schedule the UEs with resources for the transmission based on the UE conflict graph. A method for UE-centric clustering and cluster scheduling includes determining a cluster graph. Vertices in the cluster graph are CoMP clusters for one or more UEs for which there is a transmission and edges between vertices are CoMP clusters that have a scheduling conflict. The method includes transmitting signaling to assign resources to the CoMP clusters based on the cluster graph.
