Abstract

Abstract:

A distributed algorithm is proposed for resource allocation in self-organized home eNodeB (HeNB)networks. In this algorithm, each HeNB selects component carriers (CC) based on the network status. If a reselection request is received from neighboring cells, the HeNB will reselect the CC in the backup CC list, and release the CC requested by neighbors to enhance possibility of successful carrier selection. Each HeNB then adaptively performs power optimization in active CCs to reduce inter-cell interference and enhance the system capacity. Simulation results show that this resource and power allocation algorithm can enhance average user throughput and reduce the outage rate.

Key words: home eNodeB (HeNB), backup component carriers (CC) list, carrier reselection, inter-cell interference, power optimization
