Abstract
Description
Claims (3)
- 각 사용자에게 할당되는 전력을 Pt/N - 여기서, Pt는 주어진 전체 전력, N은 동시에 전송 가능한 최대 사용자수임 - 이라 가정하고 CQI(Channel Quality Indicator)를 계산하는 제 1 단계와;상기 제 1 단계 후 각 사용자에게 할당될 코드 수와 동시에 전송될 사용자의 수 n을 결정하는 제 2 단계와;상기 제 2 단계 후 사용자의 우선순위를 판별하는 제 3 단계와;상기 제 3 단계에서 판별된 우선순위에 따라 n<N일 경우 여분의 전력을 이용하여 동일한 코드 수를 가지는 MCS(Modulation and Coding Selection) 레벨 중 최대 처리량을 내는 MCS 레벨을 선택하도록 하는 제 4 단계를 포함하여 수행하는 것을 특징으로 하는 WCDMA 시스템에서의 전력 할당 방법.
- 제 1 항에 있어서, 상기 제 3 단계는,사용자의 우선 순위가 높은 사용자부터 상기 제 4 단계를 수행하도록 하는 것을 특징으로 하는 WCDMA 시스템에서의 전력 할당 방법.
- 제 1 항 또는 제 2 항에 있어서, 상기 WCDMA 시스템에서의 전력 할당 방법은,사용자의 수 n에 대해서까지 상기 제 4 단계를 수행한 후 남는 전력 자원이 있으면, n명의 사용자에게 균등 분배하여 스케줄링 하는 제 5 단계를 더욱 포함하여 수행하는 것을 특징으로 하는 WCDMA 시스템에서의 전력 할당 방법.
