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 invention 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 transmission/reception (DTX/DRX) parameters including discontinuous DTX/DRX cycle information for terminals operating in a transmission suspension mode, which is a sub-state of an active state; and b) performing DTX/DRX based on the DTX/DRX parameters in the terminals operating in the transmission suspension mode.
