Method and apparatus for transmitting ACK/NACK information in wireless communication system

摘要

A method and apparatus for transmitting ACK/NACK information in a wireless communication system are disclosed. In accordance with a method for transmitting ACK/NACK information, an ACK/NACK signal of downlink transmission in a downlink subframe set is transmitted in a single uplink subframe. In this case, if a first physical uplink control channel (PUCCH) format is established by a higher layer for a downlink receiver, and if one physical downlink shared channel (PDSCH) is transmitted in a downlink subframe set, the ACK/NACK information can be transmitted using a second PUCCH format on PUCCH resources established by a higher layer for the second PUCCH format.

1. A method for transmitting ACK/NACK information by a relay node (RN) in a wireless communication system, the method comprising:
determining a physical uplink control channel (PUCCH) format and resource which are used for transmitting ACK/NACK information in response to a backhaul downlink transmission within a downlink subframe set, wherein the downlink subframe set includes M downlink subframes where M≧1, and the M downlink subframes are configured as Multicast Broadcast Single Frequency Network (MBSFN) subframes by the RN; and transmitting the ACK/NACK information through a backhaul uplink using the PUCCH format and resource in a single uplink subframe, wherein, when the RN is configured with a PUCCH format 3 and when one physical downlink shared channel (PDSCH) is transmitted within the downlink subframe set, the ACK/NACK information is transmitted using a PUCCH format 1a/1b on a PUCCH resource configured by a higher layer for the PUCCH format 1a/1b.
