TRAFFIC LOAD DEPENDENT POWER ALLOCATION IN MULTI USER WIRELESS COMMUNICATION NETWORK WITH PROPORTIONAL FAIR SCHEDULING IN TIME AND FREQUENCY DOMAIN

摘要

A method of allocating resources in a wireless multi-user network is disclosed, comprising the following steps: - performing a proportional fair scheduling in time and frequency domain based on the bitrate for each user and the channel quality measurements for each chunk per user; and - performing a power allocation in the following way: o if the traffic load is above a threshold: allocating the uniform power to all subcarriers o if the traffic load is below the threshold, adapting a channel-dependent power allocation scheme.
