Abstract
Coordinated transmission of sounding messages between base stations and feeder stations in a wireless backhaul network is provided to facilitate accurate observations by each base station of signals from its serving feeder station and from other feeder stations in order to generate interference nulling beamforming weights for transmission to and/or reception from its serving feeder station. Likewise, these techniques facilitate accurate observations by each feeder station of signals from the base station(s) it serves and from other base stations in order to generate interfering nulling beamforming weights for transmission to and/or reception from the base station(s) it serves.
