Claims (4)
- 통신 단말에서, 제어 채널을 통해 전송된 코드워드(codeword)의 부분을 수신하는 단계(30)로서, 상기 코드워드는 공유 채널(shared channel) 상의 전송을 수신하기 위해 스케줄링된 단말의 신원(identity)을 나타내는 정보를 포함하는, 수신 단계(30);상기 통신 단말이 상기 스케줄링된 단말인지의 여부를 상기 코드워드 부분으로부터 추론하는 단계(40,50); 및상기 통신 단말이 상기 스케줄링된 단말이면, 상기 전송을 수신하기 시작하는 단계(60)를 포함하는, 방법.
- 제 1 항에 있어서, 상기 추론하는 단계는 후보 코드워드들의 콜렉션(collection)과 상기 코드워드 부분을 상관시킴으로써 확신 측정치(confidence measure)를 계산하는 단계(40) 및 상기 확신 측정치가 임계치를 초과하면 상기 통신 단말이 상기 스케줄링된 단말이라고 추론하는 단계(50)를 포함하는, 방법.
- 제 2 항에 있어서, 각각의 상관은 상기 코드워드 부분과 상기 후보 코드워드들 각각 사이에서 계산되고, 상기 확신 측정치는 상기 계산된 상관들 중 가장 큰 상관인, 방법.
- 제 1 항에 있어서, 상기 코드워드(10)는 3개의 시간슬롯들(11,12,13)을 차지하고(occupy), 상기 코드워드 부분은 상기 3개의 시간슬롯들 중 제 1 시간슬롯에서 수신되는, 방법.
