1. A method for discontinuously transmitting and/or receiving packet data to reduce power consumption of a terminal in a cellular
establishing discontinuous reception and/or transmission (DRX/DTX) parameters including DRX/DTX cycle information for terminals
in an active state in which the terminals are capable of transmitting or receiving data; and
performing DRX/DTX based on the DRX/DTX parameters for the terminals operating the DRX/DTX in the active state,
wherein the terminals operate in the active state or an idle state.
