Abstract: The present invention relates to a method for transmitting uplink control information in a mobile communication system; and, more particularly, to a method for effectively forming uplink control information transmitted through a downlink from a base station to a terminal in a mobile communication system for providing a packet service and transmitting the uplink control information with minimum radio resources occupied. The method includes the steps of generating uplink control information; allocating the uplink control information to a downlink-shared radio resource for packet data transmission based on downlink scheduling information; and transmitting the radio resource to a terminal. The present invention is applied to a mobile communication system.

Abstract: Provided is a method and apparatus for discontinuously transmitting/receiving packets for low-power consumption of a terminal in a cellular system for packet transmission. The present research provides a method and apparatus that can perform a low-power consuming operation when a terminal is in active state in a cellular system. The method for discontinuously transmitting/receiving packet data to reduce power consumption of a terminal in a cellular system, including the steps of: a) establishing discontinuous reception/transmission (DRX/DTX) parameters including discontinuous DRX/DTX cycle information for terminals operating in a transmission suspension mode, which is a sub-state of an active state; and b) performing DRX/DTX based on the DRX/DTX parameters in the terminals operating in the transmission suspension mode.
