Abstract:
1. A control channel transmitting apparatus in a communication system including a shared channel and a control channel, the shared channel being shared among a plurality of UEs (User Equipments) and spread with a plurality of channelization codes, and the control channel transmitting control information related to the shared channel to enable the UEs to receive the shared channel, the apparatus comprising: a controller for prioritizing the control information according to a processing urgency degree of the control information; a first control information generator for generating high-priority control information which includes information about a channelization code to spread the shared channel with, and a modulation scheme applied to the shared channel; a second control information generator for generating low-priority control information; a first encoder for encoding the high-priority control information in a predetermined first encoding method; a second encoder for encoding the low-priority control information in a predetermined second encoding method different from the first encoding method; and a multiplexer (MUX) for multiplexing the high-priority control information and the low-priority control information to a control channel signal such that the high-priority control information precedes the low-priority control information.
