摘要：
In one embodiment, a mobile device determines channel coefficient matrices for radio transmission from antennas at a plurality of locations, generates a power scaling vector based on the channel coefficient matrices, and selects one or more pre-coding matrices based on at least in part the power scaling vector. The antennas are operably connected to one or more base stations. The mobile device transmits the selected pre-coding matrices and the power scaling vector to the base stations, causing the base stations to transmit further data to the mobile device based on the selected pre-coding matrices and the power scaling vector.
