METHOD AND DEVICE FOR PERFORMING HARQ IN A MULTIPLE ANTENNA SYSTEM
摘要
Disclosed are a method and a device for performing HARQ in a multiple antenna system. A terminal transmits uplink data via a plurality of antennas and through a Physical Uplink Shared Channel (PUSCH), and receives an ACK/NACK (Acknowledgement / Non-Acknowledgement) signal indicating whether or not the uplink data has been received, the signal being received via the plurality of antennas and through a PHICH (Physical Hybrid-ARQ Indicator Channel) which corresponds to the PUSCH. A downlink resource to which the PHICH is mapped is determined on the basis of the index (IPRB_RA lowest_index) of the smallest Physical Resource Block (PRB) among the PRBs to which the PUSCH is mapped, uplink DMRS (Demodulation Reference Signal) cyclic shift parameters (nDMRS) and Orthogonal Code Cover (OCC) index.
