Abstract
Official abstract text for this publication.
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 (I PRB — 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 (n DMRS ) and Orthogonal Code Cover (OCC) index.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of determining a physical hybrid-ARQ indicator channel (PHICH) resource in a multi-antenna system, the method comprising: transmitting uplink data through a plurality of antennas on a physical uplink shared channel (PUSCH); and determining a PHICH resource respectively corresponding to the uplink data, wherein the PHICH resource is determined based on a lowest physical resource block (PRB) index I PRB — RA lowest — index among…
