METHOD AND SYSTEM FOR FREQUENCY REUSE IN WIRELESS RELAY SCENARIO

摘要

Disclosed is a method for frequency reuse in a wireless relay scenario. A central spectrum, an edge spectrum and a random access spectrum are pre-allocated to a cell according to scenario parameters in the cell; load conditions of all mobile stations (MSs) covered by each relay station (RS) in the cell are calculated, and reported to a base station (BS); and the BS allocates random access spectra to the RSs according to the load conditions of all the RSs and schedules the MSs. Also disclosed is a system for frequency reuse in a wireless relay scenario. Through the method and the system, spectrum planning is configurable, and random access spectra are introduced, while taking load balancing and user fairness into consideration, thereby improving the cell edge throughput, especially greatly improving the throughput of a user ranked low in throughput.
