The first stage is the outer-loop power control (OLPC), where a central network controller (CNC) operates on a larger timescale and allocates power budgets to base stations or access points. OLPC aims at controlling the inter-cell interference (ICI) in average. The individual bandwidth and power of each user are allocated on frame-level during the second stage of the resource allocation. We solve the OLPC-problem using a max-min SINR-balancing approach. Further, we introduce different strategies for reducing the feedback between BSs and the CNC and investigate the influence of the reduced feedback on the system outage performance.en621conference paper
