Abstract

This paper shows the performance comparisons of several different rate scheduling schemes for non-real time data service over the uplink of burst switching-based direct sequencecode division multiple access (DS/CDMA) system to support the integrated voice/data service. The closed-form solution of optimal scheduling formulation, which minimizes average transmission delay when all of the active data users are transmitting simultaneously, is presented and mathematical analyses with other rate scheduling schemes, which provide efficiency criterion of transmission delay for rate scheduling schemes, are performed. Numerical results show the analyses explicitly.

본 논문에서는 패킷 데이터 서비스를 지원하는 DS/CDMA 시스템에서 역방향 링크의 대기 패킷 버스트들이 겪는 평균 전송 시간을 최소화하기 위한 여러 가지 패킷 스캐줄링 방식을 비교 분석하였다. 모든 활성화된 데이터 사용자들이 동시에 전송을 하는 경우의 최적의 스케줄링 방식에 대하여 논하고 기존의 여러 가지 다른 전송률 스케줄링 방식들과의 수학적인 비교 분석을 통하여 평균 전송 지연을 고려한 전송률 스케줄링 방식의 효율적인 지표를 제시하였다.
