CDMA 셀룰러 시스템에서는 통신 품질을 목표 수준으로 유지하기 위해 신호 대 간섭비(SIR) 기반 전송 전력 제어 방법이 개발되었습니다. 그러나 이러한 전력 제어 방법은 전력 수준만 제어하기 때문에 트래픽의 지리적 편차가 큰 경우 시스템 효율성을 반드시 향상시키지는 않습니다. 셀 경계의 이동은 셀 간의 트래픽 균형을 제어할 수 있습니다. 본 논문에서는 트래픽이 균일하지 않은 상황에서 단말이 상향링크와 하향링크 각각에 대해 기지국(BS)을 적응적으로 선택할 때 셀 경계의 최적 위치와 전력 레벨을 평가한다. 업링크와 다운링크 사이의 시스템 구조의 비대칭성으로 인해 최적의 셀 경계가 두 링크 모두에 대해 항상 일치하는 것은 아닙니다. 셀 경계의 위치는 다운링크의 직교성 손실에 따라 이동하는 것으로 나타났습니다.

Abstract: In order to maintain the communications quality at a target level, signal-to-interference ratio (SIR)-based transmission power control methods have been developed in CDMA cellular systems. These power control methods, however, do not necessarily improve system efficiency when there is a large geographic deviation in traffic because they only control power levels. A shift in the cell boundary can control traffic balance between cells. In this paper, we evaluate the optimum location of the cell boundary and the power levels when a mobile station adaptively selects a base station (BS) for each of uplink and downlink under non-uniform traffic. Because of the asymmetry in system structure between uplink and downlink, the optimum cell boundaries are not always coincident for both the two links; the location of the cell boundary is found to migrate according to the loss in orthogonality in the downlink.
