Abstract
Description
Claims (1)
- 무선통신시스템의 단말에서 전력 제어 방법에 있어서,전송신호의 전력을 증폭하는데 소요되는 지연 시간을 확인하는 과정과,사운딩 기준 신호 영역의 앞과 뒤에 위치하는 데이터 심볼의 데이터 할당 정보를 확인하는 과정과,상기 지연 시간과 상기 데이터 할당 정보를 고려하여 사운딩 기준 신호에 대한 전력 설정 시작 시점과 다음 TTI(Transmission Time Interval)에 포함되는 데이터 심볼에 대한 전력 설정 시작 시점을 결정하는 과정을 포함하는 것을 특징으로 하는 방법.
