Greedy and Progressive User Scheduling for CoMP Wireless Networks

In this paper, the authors propose Progressive User Scheduling (PUS) and distributed Successive Zero-Forcing (SZF) precoding for clustered Coordinated Multi-Point transmission/reception (CoMP) systems. With Joint Transmission (JT) across a cluster of cells, centralized processing of precoding and user scheduling requires significant bandwidth resources for information exchange among coordinated Base Stations (BTSs) and the central controller, and Channel State Information (CSI) feedback from all users in the cluster to the central controller. In this paper, they propose a greedy Progressive User Scheduling (PUS) and distributed SZF precoding to reduce CSI feedback and information exchange.
