On a User-Centric Base Station Cooperation Scheme for Reliable Communications

摘要

In this paper, we describe CoMP2flex, a user-centric base station (BS)cooperation scheme that provides improvements in reliability of both uplink(UL) and downlink (DL) communications of wireless cellular networks. CoMP2flexsupports not only cooperation of two BSs with same direction of traffic butalso cooperation of two BSs serving bidirectional traffic. The reliabilityperformance of CoMP2flex is shown with numerical simulations and analyticalexpressions. We quantify and numerically validate the performance of the greedyBS pairing algorithm by comparing maximum weight matching methods, implementedas the Edmonds matching algorithm for weighted graphs.
