METHOD AND APPARATUS FOR TRANSMITTING REVERSE ACK/NACK FOR FORWARD CONTROL CHANNEL IN MOBILE COMMUNICATION SYSTEM SUPPORTING HARQ

摘要

A method and apparatus for transmitting a reverse ACK/NACK for a forward control channel in a mobile communication system supporting HARQ are provided. Control information is received for decoding a packet from a base station over the forward control channel. The packet from the base station is received in an HARQ scheme over a forward data channel. An ACK/NACK for the control information is transmitted to the base station over a first reverse ACK channel, when an mth sub-packet corresponding to each retransmission of the packet is received from the base station. Here, m is a predetermined integer greater than or equal to two.
