1. A method to transmit a data packet by a user equipment (UE) in a wireless communication system, the method comprising:

  • entering a low power mode, the low power mode being configured to enable data transmission or reception by the UE when the UE determines a user inactive state and when a channel state of a wireless channel exceeds a transmission threshold, the UE in the low power mode being in a radio resource control (RRC) connected state but not in an idle state;

    comparing an index indicating the channel state with the transmission threshold upon occurrence of a data packet to be transmitted to a base station;

    initiating a transmission of the data packet on the wireless channel when the index indicating the channel state exceeds the transmission threshold; and

    continuing the transmission of the data packet in the user inactive state until an on-duration timer that starts from a point of the initiation of the transmission of the data packet expires.
