METHOD OF TRANSMITTING CONTROL INFORMATION AND DEVICE FOR SAME

摘要

The present invention relates to a wireless communication system. In more detail, a method of a communication device to perform Hybrid Automatic Repeat reQuest (HARQ) retransmission in a wireless communication system includes: initially transmitting a data block to a base station; attempting to detect a Physical Downlink Control Channel (PDCCH) in a predetermined time interval including a plurality of subframes after the uplink channel signal is transmitted; and retransmitting the data block when the PDCCH signal for a command to retransmit the data block is detected in the predetermined time interval. A method of skipping a Physical hybrid ARQ indicator Channel (PHICH) reception process corresponding to the initial transmission of the data initial block and a device for same are provided.
