Claims (9)
- TDD(Time Division Duplex) 무선 통신 시스템에서의 제어 정보의 전송 방법에 있어서,ACK/NACK(acknowledgement/non-acknowledgement) 신호를 나르는 데이터 심벌들과 상기 ACK/NACK 신호와 동일한 ACK/NACK 신호를 나르는 미드앰블(midamble)을 포함하는 버스트(burst)를 구성하고,상기 버스트를 HS-DSCH(high speed downlink shared channel)를 위한 공통 정보 채널인 HS-SICH(high speed shared inforamtion channel)을 통해 전송하는 것을 포함하는 제어 정보의 전송 방법.
- 제 1 항에 있어서,상기 미드앰블은 상기 데이터 심벌들 상으로 날라지는 ACK/NACK 신호가 ACK 신호인지 NACK 신호인지에 따라 서로 다른 위상으로 변조되는 것을 특징으로 하는 제어 정보의 전송 방법.
- 제 2 항에 있어서,상기 데이터 심벌들 상으로 ACK 신호가 날라지는 경우, 상기 미드앰블은 위상 0에 의하여 QPSK(quadrature phase shift keying) 변조되고,상기 데이터 심벌들 상으로 NACK 신호가 날라지는 경우, 상기 미드앰블은 위상 π/4에 의하여 QPSK 변조되는 것을 특징으로 하는 제어 정보의 전송 방법.
- 제 1 항에 있어서,상기 미드앰블은 상기 데이터 심벌들 상으로 날라지는 ACK/NACK 신호가 ACK 신호인지 NACK 신호인지에 따라 서로 다르게 순환 쉬프트(cyclic shift) 되는 것을 특징으로 하는 제어 정보의 전송 방법.
- 제 1 항에 있어서,상기 미드앰블은 상기 데이터 심벌들 상으로 날라지는 ACK/NACK 신호가 ACK 신호인지 NACK 신호인지에 따라 서로 다르게 구성되는 것을 특징으로 하는 제어 정보의 전송 방법.
- 제 5 항에 있어서,상기 데이터 심벌들 상으로 ACK 신호가 날라지는 경우, 상기 버스트 내에 제1 미드앰블이 할당되며,상기 데이터 심벌들 상으로 NACK 신호가 날라지는 경우, 상기 버스트 내에 제2 미드앰블이 할당되는 것을 특징으로 하는 제어 정보의 전송 방법.
- 무선 통신 시스템에서 HARQ(hybrid automatic repeat request)를 수행하는 방법에 있어서,하향링크 데이터를 수신하고,상기 하향링크 데이터에 대한 ACK/NACK(acknowledgement/non-acknowledgement) 신호를 버스트(burst)를 통해 전송하는 것을 포함하되,상기 버스트는 ACK/NACK(acknowledgement/non-acknowledgement) 신호를 나르는 데이터 심벌들과 상기 ACK/NACK 신호와 동일한 ACK/NACK 신호를 나르는 미드앰블(midamble)을 포함하고,상기 버스트는 HS-DSCH(high speed downlink shared channel)를 위한 공통 정보 채널인 HS-SICH(high speed shared inforamtion channel)을 통해 전송되는 것을 특징으로 하는 방법.
- 제 7 항에 있어서,상기 미드앰블은 상기 데이터 심벌들 상으로 날라지는 ACK/NACK 신호가 ACK 신호인지 NACK 신호인지에 따라 서로 다른 위상으로 변조되는 것을 특징으로 하는 방법.
- 제 7 항에 있어서,상기 미드앰블은 상기 데이터 심벌들 상으로 날라지는 ACK/NACK 신호가 ACK 신호인지 NACK 신호인지에 따라 서로 다르게 순환 쉬프트(cyclic shift) 되는 것을 특징으로 하는 방법.
