APPARATUS AND METHOD FOR DYNAMIC CHANNEL ALLOCATION IN MULTI-CELL DOWNLINK SYSTEM

摘要

A method for dynamically allocating channels in a multi-cell downlink system is provided to increase performance about throughput per unit area as compared to other channel allocation techniques by allocating a channel in consideration of a mobile terminal's interference range dependent on the distance between a base station and the mobile terminal. A base station, if a channel allocation request is detected, checks whether unassigned channels exist(600,602). If unassigned channels exist, the base station selects one of the unassigned channels(604). On the assumption that the selected channel is allocated, the base station judges whether the selected channel has influence on mobile terminals which belong to neighbor base stations(606). In case it is judged that any of the mobile terminals which belong to neighbor base stations is not influenced by the selected channel, the base station allocates the selected channel(610). Then the base station transmits downlink channel allocation information to the neighbor base stations, including allocated channel information(612).
