Apparatus and method for transmitting and receiving control information in a wireless communication system

摘要

Disclosed are an apparatus and a method for transmitting/receiving control information in a wireless communication system. In a repeater according to the present invention, a receiving antenna can receive control information for a hybrid automatic repeat reQuest ACKnowledgement (HARQ ACK) feedback on the data transmission of a base station from the base station through higher layer signaling. On the basis of the control information, a processor can determine a resource in an upper link control channel to be used for the transmission of the HARQ feedback. A transmitting antenna can transmit the HARQ feedback to the base station through the resource that has been determined.

1. A method for transmitting uplink control information at a relay node (RN) in a wireless communication system, the method comprising:
receiving, a resource index (nPUCCH(1,p)) related to a transmission of a physical uplink control channel (PUCCH) format 1a or 1b for an antenna port p, from an eNode B (eNB) through higher layer signaling; receiving, a relay physical downlink control channel (R-PDCCH) including a physical downlink shared channel (PDSCH) assignment information for the RN, from the eNB; receiving a PDSCH for the RN based on the R-PDCCH from the eNB; identifying a resource for the transmission of the PUCCH format 1a or 1b for the antenna port p based on the resource index (nPUCCH(1,p)), the PUCCH format 1a or 1b for the antenna port p including a hybrid automatic repeat request (HARQ) feedback associated with the PDSCH for the RN; and transmitting the PUCCH format 1a or 1b for the antenna port p using the resource to the eNB.
