Abstract:
Briefly, in accordance with one or more embodiments, mobile station or user equipment receives pilot signals from two or more infrastructure nodes in a distributed antenna system, and calculates phase or timing information, or combinations thereof, from the pilot signals. The mobile station feeds back the phase or timing information, or combinations thereof, to the infrastructure nodes, and then receives one or more subsequent transmissions from the infrastructure nodes with phase shift or timing adjustments, or combinations thereof, calculated by the infrastructure nodes and applied to the spatial streams transmitted by the infrastructure nodes.
