Position-based power planning for fair resource allocation in LTE-A

This paper considers the use of predefined frequency-domain power profiles in downlink LTE-A aiming at making interference predictable across the Physical Resource Blocks, to be combined with fair resource allocation. In particular, the power profile structure is defined depending on the position of the users and fairness-oriented scheduling strategies are considered. Evaluations of the throughput and fairness achieved in the system depending on different scheduling algorithms are reported, as well as a comparison with scheduling strategies implementing power control techniques at similar complexity. Results show that, when resource allocation is SINR-based and focuses on cell-edge users, the highest sum rate and average per user rate is achieved without significant loss from the optimum fairness.
