Hybrid interference alignment for mixed macro-FEMTO base station downlink

摘要

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus is a first BS. The apparatus determines a first channel between a second BS and a first UE served by a third BS, determines a second channel between the first base station and the first UE, and determines a first direction vector to be used by the second base station for sending a data transmission. The apparatus transmits a set of resource blocks to a second UE served by the first base station with a second direction vector determined based on the first channel, the second channel, and the first direction vector to be used by the second base station.
