Abstract

다중 안테나 시스템에서 HARQ 수행 방법 및 장치가 제공된다. 단말은 PUSCH(Physical Uplink Shared Channel) 상으로 복수의 안테나를 통해 상향링크 데이터를 전송하고, 상기 PUSCH에 대응되는 PHICH(Physical Hybrid-ARQ Indicator Channel) 상으로 상기 복수의 안테나를 통해 상기 상향링크 데이터의 수신 여부를 지시하는 ACK/NACK(Acknowledgement/Non-Acknowledgement) 신호를 수신한다. 상기 PHICH가 맵핑되는 하향링크 자원은 상기 PUSCH가 맵핑된 PRB(Physical Resource Block) 중 가장 작은 PRB의 인덱스(IPRB_RA lowest_index), 상향링크 DMRS(Demodulation Reference Signal) 순환 쉬프트 파라미터(nDMRS) 및 OCC (Orthogonal Code Cover) 인덱스를 기반으로 결정된다.
