METHOD OF TRANSMITTING CONTROL INFORMATION AND DEVICE FOR SAME

摘要

The present invention relates to a wireless communication system and, specifically, to a method for performing hybrid automatic repeat request (HARQ) retransmission using a communication device in a wireless communication system comprising the following steps of: initially transmitting a data block to a base station; trying physical downlink control channel (PDCCH) detection in a predetermined time section including multiple subframes after transmitting an uplink channel signal; retransmitting the data block in case the PDCCH signal ordering retransmission of the data block is detected in the predetermined time section; and skipping a physical hybrid ARQ indicator channel (PHICH) reception process corresponding to initial transmission of a data initial block.
