Abstract
A system and method for passive coordination of base stations in a closed-loop multiple-input multiple-output wireless communication system, includes a first stepof allocating a subframe zone to be used by a serving base station and a neighboring base station to provide synchronized communications. A next stepincludes defining at least one beam combination for the base stations, the beam combination to be used over at least one resource block of the allocated zone. A next stepincludes reporting feedback on measured channel conditions for the zone at a first time for the at least one beam combination and associated resource block of the zone. A next stepincludes providing synchronized communications using the feedback by the base stations over the zone at a second time by repeating the same associated at least one beam combination and associated resource block of the zone.
