Dynamic resource allocation with inter-cell interference coordination for 3GPP LTE

Abstract

In this paper, we propose distributed dynamic resource allocation schemes for future cellular networks to enable efficient utilization of the whole available frequency spectrum. Our algorithms are simple, so that fast resource allocation decisions can be made at the base stations. To enable coordination between base stations, our schemes require inter-base-station signaling of system state information every update interval; we consider different update intervals ranging from milliseconds to seconds. When the load is not too high, our schemes yield gains in average user throughput and the 10% quantile of the user rate distribution compared to an uncoordinated full frequency reuse system. While our schemes are applicable to any OFDMA or TDMA wireless access technology, we focus on their applications to LTE.
