IEEE802.16j 기반의 2-홉 셀룰러 중계시스템에서 하향링크 접근영역과 중계영역에 대한 최적 무선자원 할당방법 연구 = A Study on the Optimal Wireless Resource Allocation for the Access and Relay Zones of Downlink in a 2-hop Cellular Relay System based on IEEE802.16j

다국어 초록 (Multilingual Abstract)

In this paper, we evaluate the system throughput and the method of optimal wireless resource allocation for the access zone (AZ) and relay zone (RZ) in downlink when the cell coverage is extended using the non-transparent Relay Station (RS) in a 2-hop cellular relay system based on IEEE802.16j, which uses the OFDMA-TDD structure. For the analyses, we first introduce the MAC (Media Access Control) frame structure in the non-transparent mode, then we investigate the interfering elements in both AZ and RZ for the network devices such as the Mobile Station (MS) and RS. Through computer simulation, we analyze the cell coverage extension and system throughput in terms of the distance between Base Station (BS) and RS, then we present the amount of the optimal allocation of wireless resource for the AZ and RZ in downlink using our results.
