Sum-rate balancing in wireless multicell and multicarrier system

摘要

A method in a communication node of a wireless communications system that provides at least two communication links each having at least two frequency channels. The communication node is configured to communicate with a receiving communication node over a link under influence of interference from surrounding transmitter(s) using said frequency channels. The method includes determining a target for said link for the sum of the data rates and allocating power on the frequency channels to reach said target while minimizing the sum of the power on said link.
