METHOD AND APPARATUS FOR TRANSMITTING DOWNLINK HYBRID AUTOMATIC REPEAT REQUEST INFORMATION IN WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a method and an apparatus for transmitting downlink hybrid automatic repeat request information in a wireless communication system, and the method for transmitting the downlink hybrid automatic repeat request information comprises the steps of: setting at least one physical resource block (PRB) for transmitting a physical HARQ indicator channel (PHICH) from all of the PRBs which comprise a usable frequency band; selecting a PHICH resource within the at least one PRB that is set; and transmitting the PHICH signal using the PHICH resource that is selected.
