Cooperative radio resource allocation in a wireless communication network and methods for use therewith

Abstract

A cooperative radio resource manager operates by: obtaining constraint data indicating a plurality of radio network constraints and channel state information (CSI) corresponding to wireless communications between a plurality of client devices and a plurality of remote radio heads; performing a first sub-problem optimization, subject to the plurality of radio network constraints, to generate an remote radio head (RRH) to client device association that associates a corresponding one of the plurality of remote radio heads to each of the plurality of client devices and further to generate a physical resource block (PRB) allocation that allocates PRBs of each RRH among the plurality of client devices. The cooperative radio resource manager can also operate by performing a second sub-problem optimization, subject to a subset of the plurality of radio network constraints, to generate a power allocation (PA) that allocates power for uplink and downlink transmissions between the plurality of remote radio heads and the plurality of client devices, based on the RRH to client device association and the PRB allocation generated via the first sub-problem optimization, for example. In either case, the cooperative radio resource manager can facilitate fronthaul communications via a radio network interface to control the wireless communications between the plurality of remote radio heads and the plurality of client devices via the RRH to client device association, the PRB allocation and/or the PA.
