Abstract:
1. A computer implemented method for coordinating beamformed data transmissions in a wireless communication system, the method comprising: providing first and second base stations being associated with first and second mobile stations, respectively, at a given time period; scheduling a first data package in a first wireless resource with a first phase adjustment at the first base station in coordination with an associated second phase adjustment of a second wireless resource at the second base station; transmitting the first data package as a first beamformed signal to the first mobile station by the first base station, the first beamformed signal being transmitted with the first phase adjustment; and transmitting a second data package as a second beamformed signal to the second mobile device by the second base station, the second beamformed signal being transmitted with the second phase adjustment, the second data package being different than the first data package, wherein the first mobile station receives the first beamformed signal as communication from the first base station and the second beamformed signal as interference from the second base station, and wherein the first phase adjustment and the second phase adjustment are associated via a first phase adjustment map associated with the first base station and a second phase adjustment map associated with the second base station, the first phase adjustment map and the second phase adjustment map aligning the first wireless resource and the first phase adjustment with the second wireless resource and the second phase adjustment.
