A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a serving base station. The serving base station receives channel feedback from a plurality of UEs. The channel feedback is based on predetermined phase rotations used by the serving base station. The serving base station selects at least one UE of the UEs for a data transmission based on the received channel feedback. The serving base station maps at least one data stream to a set of resource blocks. The serving base station transmits the set of resource blocks to the at least one UE with a phase rotation determined based on the predetermined phase rotations.
