Abstract
Description
Claims (3)
- 이동 통신 단말기의 수신단을 통해 기지국으로부터 수신한 파일롯 신호에 대한 Ec/Io(수신 대역에서 총전력 스펙트럼 밀도에 대한 하나의 PN칩 기간동안 누적된 파일롯 에너지 비율) 값을 측정하는 과정과;상기 측정된 Ec/Io 값이 기설정된 기준 Ec/Io 값보다 큰 지를 판단하는 과정과;상기 판단결과 상기 측정된 Ec/Io 값이 상기 기준 Ec/Io 값보다 작은 경우에는, LNA 제어를 담당하는 LNA 제어부로 상기 측정된 Ec/Io 값이 상기 기준 Ec/Io 값보다 작다는 사실을 통보하는 과정과;상기 LNA 제어부에서 상기 측정된 Ec/Io 값이 상기 기준 Ec/Io 값보다 작다는 통보에 따라 LNA가 고이득 모드로 동작되도록 제어하는 과정을 포함하여 이루어지는 이동 통신 단말기의 엘엔에이 제어 방법.
- 제 1항에 있어서, 상기 판단결과 상기 측정된 Ec/Io 값이 상기 기준 Ec/Io 값보다 큰 경우에는, 상기 수신 파일롯 신호에 대한 신호 세기를 측정하여 상기 LNA 제어부 전달하는 과정과;상기 LNA 제어부에서 상기 전달받은 신호 세기가 기설정된 기준 신호 세기보다 큰 지를 판단하는 과정과;상기 판단결과 상기 전달받은 신호 세기가 기설정된 기준 신호 세기보다 작 은 경우에는, 상기 LNA가 고이득 모드로 동작되도록 제어하는 과정을 더 포함하여 이루어지는 것을 특징으로 하는 이동 통신 단말기의 엘엔에이 제어 방법.
- 제 2항에 있어서, 상기 판단결과 상기 전달받은 신호 세기가 기설정된 기준 신호 세기보다 큰 경우에는, 상기 LNA가 중간 이득 모드와 저이득 모드 중에서 어느 하나로 동작되도록 제어하는 과정을 더 포함하여 이루어지는 것을 특징으로 하는 이동 통신 단말기의 엘엔에이 제어 방법.
