Method and System for Frequency Reuse in Wireless Relay Scenario
First Claim
1. A method for frequency reuse in a wireless relay scenario, comprising:
- pre-allocating a center frequency spectrum, an edge frequency spectrum and a random access frequency spectrum to a cell according to a scenario parameter in the cell;
calculating load conditions of all mobile stations (MSs) covered by each relay station (RS) in the cell and reporting the load conditions to a base station (BS);
the BS allocating the random access frequency spectrum to an RS according to load conditions of all RSs and scheduling an MS.

Abstract
The disclosure provides a method for frequency reuse in a wireless relay scenario, wherein a center frequency spectrum, an edge frequency spectrum and a random access frequency spectrum are pre-allocated to a cell according to a scenario parameter in the cell; load conditions of all mobile stations (MSs) covered by each relay station (RS) in the cell is calculated and reported to a base station (BS); the BS allocates the random access frequency spectrum to an RS according to load conditions of all RSs and schedules MSs. The disclosure also provides a system for frequency reuse in a wireless relay scenario. With the method and system above, the frequency spectrum planning is configurable, the random access frequency spectrum is introduced, and both the load balancing and user fairness are taken into consideration, which improves the throughput at the edge of the cell, especially can increase the throughput for the users whose throughput ranks poorly.
