Claims (7)
- 무선 링크(20)를 통한 전송 방법으로서,상기 무선 링크를 통한 무선 전송에 대해 다수의 기대 ACK의 수와, 손실 ACK의 수와 수신 ACK의 수 중의 하나와 관련하여, 무선 전송기(12, 24)의 전송 파워를 조정하는 단계를 포함하되, 상기 다수의 기대 ACK의 수는 N개인무선 링크를 통한 전송 방법.
- 제 1 항에 있어서,상기 조정은 상기 무선 전송기(12, 24)에 의해 수행되며,상기 전송 방법은,전송된 무선 패킷에 대한 손실 ACK의 수를 모니터링하는 단계와,상기 손실된 ACK 수/기대 ACK 수가 제1 임계값보다 크면 상기 전송 파워를 증대시키는 단계와,상기 손실된 ACK 수/기대 ACK 수가 제2 임계값 보다 작으면 상기 전송 파워를 감소시키는 단계를 더 포함하는 무선 링크를 통한 전송 방법.
- 제 1 항에 있어서,상기 무선 링크(20)를 통해 수신된 신호의 측정치에 근거하여 상기 무선 전송기(12, 24)에 대한 초기 전송 파워를 결정하는 단계를 포함하는 무선 링크를 통한 전송 방법.
- 제 2 항에 있어서,상기 무선 링크(20)를 통해 상기 무선 전송기(12)가 기지국(22)에 전송한 상기 무선 패킷의 긍정 응답을 전송하는 상기 기지국(22)을 제공하는 단계를 포함하는 무선 링크를 통한 전송 방법.
- 제 2 항에 있어서,상기 무선 링크(20)를 통해 상기 무선 전송기(24)가 상기 무선 전송기(12)에 전송한 무선 패킷의 긍정 응답을 전송하는 무선 전송기(12)를 제공하는 단계를 포함하는 무선 링크를 통한 전송 방법.
- 제 1 항에 있어서,길이 N의 레지스터를 제공하는 단계와,상기 레지스터를 수신 ACK 비트로 채우는 단계와,무선 패킷을 전송하는 단계와,만일 ACK가 소정 주기의 시간 내에 수신되었으면, 수신 ACK 비트를 상기 레지스터에 삽입하는 단계와,만일 ACK가 상기 소정 주기의 시간 내에 수신되지 않았으면, 무 ACK 비트(no ACK BIT)를 상기 레지스터에 삽입하는 단계를 더 포함하는 무선 링크를 통한 전송 방법.
- 제 6 항에 있어서,상기 조정 단계는,만일 무 ACK 비트 수/N이 제1 임계값보다 작으면 상기 전송 파워를 감소시키는 단계와,만일 무 ACK 비트 수/N이 제2 임계값보다 크면 상기 전송 파워를 증대시키는 단계를 포함하는 무선 링크를 통한 전송 방법.
