Joint Uplink Scheduling and Interference Mitigation in Multicell LTE Networks

Uplink resource allocation with intercell interference mitigation in LTE networks is investigated. A non-cooperative probabilistic interference avoidance scheme and a pricing-based cooperative power control scheme are proposed. A scheduling algorithm is presented and used with the proposed interference mitigation schemes. In the absence of power control, scheduling with the probabilistic interference avoidance scheme is shown to lead to considerable enhancements over classical reuse schemes. When cooperative power control is added, the proposed approach is shown to outperform the standard LTE power control approach.
