Apparatus and method for transmitting/receiving high speed shared control channel in wideband wireless communication system

摘要

Provided is an apparatus and method for transmitting/receiving an HS-SCCH in a wideband wireless communication system. In a method for transmitting control information in an HARQ wireless communication system, an ACK/NACK fed back from a receiver is monitored to determine if an ACK/NACK repetition factor needs to be adjusted. If the adjustment is needed, the ACK/NACK repetition factor is determined. Control information corresponding to the ACK/NACK repetition factor is transmitted to the receiver over a predetermined control channel. A Node B capable of directly detecting the uplink channel conditions, adjusts the ACK/NACK repetition factor and the adjusted ACK/NACK repetition factor is rapidly transmitted to a UE.
