METHOD AND ARRANGEMENT IN A WIRELESS COMMUNICATION SYSTEM

摘要

The present invention concerns power allocation for a multi-carrier system encompassing multiple interfering links. Hence, in embodiments of the present invention the powers used on the different spectrum resources/bands/subcarriers are adjusted such that each user meets a target sum-rate, i.e. the sum of the rates over the available channels on one or more links (carriers). In this way, a power and rate control is achieved that incorporates the aspect of multiple bands and/or subcarriers.

主权项

1. A method in a communication node of a wireless communications system providing at least two communication links each having at least two frequency channels, wherein 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 comprises the steps of:
determining (201) a target for said link for the sum of the data rates; and allocating (202) power on the frequency channels to reach said target while minimizing the sum of the power on said link.
