본 논문에서는 패킷 데이터 서비스를 지원하기 위해 DS/CDMA 시스템의 다운링크를 통한 두 가지 패킷 스케줄링 방식을 조사합니다. 이러한 방식에는 CDX(Code Division Multiplexing) 기반 패킷 스케줄링과 TDX(Time Division Multiplexing) 기반 패킷 스케줄링이 있습니다. 각 방식을 보다 효과적으로 평가하기 위해 전력 제약 방정식을 기반으로 한 성능 측정값으로 다운링크의 처리량 이득을 도출합니다. 또한, 동시 데이터 사용자의 패킷 길이가 지수 분포에 따라 독립적이고 동일하게 분포될 때 각 방식의 패킷 전송 지연을 도출하여 서로 비교한다. 다운링크 용량은 직교성 요소와 밀접한 관련이 있으므로, 우리의 분석 결과는 처리량 이득과 전송 지연이 이 요소에 크게 의존한다는 것을 보여줍니다. 또한, CDMA 다운링크에서 TDX 스케줄링 기법은 직교성 인자가 약 1인 경우를 제외하고는 CDX 스케줄링 기법보다 더 나은 성능을 제공하는 것으로 나타났습니다.

Abstract: In this paper, we investigate two packet scheduling schemes over the downlink of DS/CDMA systems to support packet data service. These schemes are the code division multiplexing (CDX)-based packet scheduling and the time division multiplexing (TDX)-based packet scheduling. To evaluate each scheme more effectively, we derive the throughput gain of the downlink as a performance measure based on the power constraint equation. In addition, the packet transmission delay of each scheme is derived and compared each other when the packet lengths of the concurrent data users are independently and identically distributed according to the exponential distribution. As the downlink capacity is quite related to the orthogonality factor, our analysis shows from the results that the throughput gain and the transmission delay are highly dependent on this factor. Furthermore, it is shown that the TDX scheduling scheme in CDMA downlink affords better performances than the CDX scheduling scheme, except when the orthogonality factor is around 1.
