Abstract
An apparatus and method for transmitting/receiving an HS-SCCH in an HSDPA communication system including an HS-DSCH shared among a plurality of UEs and spread with a plurality of channelization codes, and the HS-SCCH for transmitting control information related with the HS-DSCH to enable the UEs to receive the shared channel. In the HS-SCCH transmitting apparatus, the control information is prioritized according to its processing urgency degree. High-priority control information and low-priority control information are generated and encoded in different encoding methods. Then the high-priority control information and the low-priority control information are multiplexed to a control channel signal such that the high-priority control information precedes the low-priority control information.
