摘要:
A system and method for spatial multiplexing for coordinated multi-point transmission are provided. A method for communications device operations includes receiving transmissions from at least two access points, measuring channels between the communications device and each of the at least two access points based on the received transmissions, computing beamforming weights based on the measured channels, and transmitting the beamforming weights to the at least two access points. The computing is based on attempting to maximize a capacity of a communications system containing the communications device and the at least two access points with the beamforming weights, and the beamforming weights are used at the at least two access points to beamform transmissions to the communications device using coordinated multi-point transmission.
