Abstract :
In a wireless system, the relay station (RS) is introduced to increase the data rate of a mobile station (MS) in a shadowing area or a cell edge. RS is stationary of non-stationary and takes charge of relaying between a base station (BS) and an MS. However, the adoption of several RSs causes inefficient time-slot. In this paper we propose a novel algorithm for utilizing RSs and provide an appropriate frame structure. We divide the zone into two, inner and outer zone for a sectorized cell structure. RSs are stationary at inner zone edge in each sector and connect an MS at outer zone with a BS. And a special time-slot is shared by all RSs existing in the same sector. The proposed algorithm will increase the opportunity of connection between a BS and an MS out of RS coverage. Simulation result shows that throughout increases about three times in inner and outer zone.
