사용자 간의 상호 간섭은 다른 셀의 간섭을 급격히 증가시켜 공존하는 WCDMA 및 HSDPA 시스템에 과부하 상황을 초래할 수 있습니다. 트래픽 과부하로 인해 시스템 성능이 저하될 수 있습니다. 본 논문에서는 WCDMA와 HSDPA 시스템의 공존 시 과부하로 인한 성능 저하를 줄이기 위한 새로운 DDLC(Dynamic Downlink Load Control) 알고리즘을 제안한다. 제안된 알고리즘은 두 가지 부하 제어 임계값으로 분류된 부하 상태에 따라 하향링크 부하를 제어하고, 하향링크 부하 및 채널 변화에 따라 사용자가 보고하는 CQI 값을 동적으로 조정하여 트래픽 과부하를 완화한다. 제안된 알고리즘을 시뮬레이션한 결과, DDLC 방식은 정전 확률, 전체 시스템 처리량 및 무선 자원 활용 측면에서 WCDMA 및 HSDPA 시스템의 성능을 향상시키는 것으로 나타났습니다.

Abstract: Mutual interference among users can abruptly increase othercell interference and cause overload situation in coexisting WCDMA and HSDPA systems. Traffic overloading can degrade the performance of the systems. This letter proposes a new dynamic downlink load control (DDLC) algorithm to reduce performance degradation due to overload in the coexistence of WCDMA and HSDPA systems. With the proposed algorithm, the downlink load is controlled according to load states classified by two load-control thresholds, and traffic overloading is alleviated by dynamically adjusting the CQI values reported by users, based on the downlink load as well as channel variations. The proposed algorithm is simulated and results show that the DDLC scheme improves the performance of both WCDMA and HSDPA systems in terms of outage probability, total system throughput, and radio resource utilization.
