Abstract
The present invention relates to a system for gating a dedicated physical control channel in a mobile communication system. A UTRAN (UMTS Terrestrial Radio Access Network) transmits a gating start command or a gating end command to a UE (User Equipment) through a specific transport format combination indicator symbol according to whether there exists data transmitted over a downlink physical shared channel and a dedicated physical data channel, thereby to start or end gating the dedicated physical control channel.
