Abstract

본 연구에서는 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE)와 같은 이동통신 네트워크에서 역방향 전송이 전용회선 방식이 아닌 패킷 전송으로 이루어지는 환경에서의 고신뢰성 역방향 패킷 스케줄링 기법을 제안하고, 기존 방안과 성능을 비교하여 장단점을 분석한다. 제안하는 고신뢰성 역방향 패킷 스케줄링 기법은 전송속도 혹은 처리용량의 극대화를 추구하는 기존 방식과 다르게 현재 차세대 이동통신의 핵심 연구 분야로 고려되는 Machine Type Communication (MTC) 분야에서, 단말의 위치 및 단말의 무선링크 상태에 독립적으로, 반드시 단말이 생성한 정보가 네트워크로 전송되어야 하는 요구사항을 만족하도록 제안되었으며, 성능 평가를 통하여 제안방안이 기존 방안 대비 우수한 신뢰성을 제공하는 것을 확인하였다. In this paper, we propose the reliability constrained resource allocation scheduling algorithm in cellular network for uplink transmission, where uplink transmission is supported via packet switching schemes without the dedicated uplink circuit links. We evaluate the performance of the proposed algorithm, and compared with the conventional works to identify the pros and cons. The proposed uplink scheduling algorithm is to satisfy the constraints requirements of the MTC services which is considered as the core technology for future mobile wireless networks. It is different to conventional works which target to maximize the link capacity. The proposed algorithm provides reliable uplink transmission independent to the location and the quality of the wireless link of the mobile terminal. Based on the performance evaluation results, we conclude that the proposed method provides enhanced reliability performance than conventional works.
