Claim 0:
1. In a cellular communications network comprising a plurality of transmitting sites that include a first transmitting site and a second transmitting site, a method of transmitting data to a target mobile terminal, comprising:
receiving, at the first transmitting site from the target mobile terminal, a first precoder, the first transmitting site comprising a first antenna array;
receiving, at the second transmitting site from the target mobile terminal, a second precoder and phase correction feedback based on one or more phase differences of signal frequencies detected by the target mobile terminal, the second transmitting site comprising a second antenna array;
transmitting, from the first transmitting site, a first data stream to the target mobile terminal using a first beam formed by the first antenna array; and
transmitting, from the second transmitting site, a second data stream to the target mobile terminal using a second beam formed by the second antenna array, wherein the second transmitting site performs a phase correction based on the phase correction feedback to result in constructive addition of the first and second beams upon arriving at the target mobile terminal, the phase correction being performed by applying random phase sequences to determine a best phase combination.
