Distributed computation of precoding weights for coordinated multipoint transmission on the downlink

摘要

A method of coordinating multipoint transmissions in a mobile communication network having coordinated multipoint cells that overlap. Said method comprises: receiving, from serving cells in two or more coordinated multipoint cells, transmit power requirements for one or more transmit antennas shared by said two or more coordinated multipoint cells; determining power availability for each shared transmit antenna based on said received transmit power requirements; and reporting said power availability for each shared antenna to said serving cells.
