Apparatus and method for transceiving data by user terminal
First Claim
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.

Abstract
The present invention is a method for transmitting a data packet by a user terminal in a mobile communication system. The method enters a power saving mode for transmitting the data packet only if a channel state satisfies a transmission threshold value, compares the index indicating the channel state and the transmission threshold value upon occurrence of a data packet to be transmitted, starts transmission of the data packet if the index indicating the channel state is greater than the transmission threshold value, and proceeds with the transmission of the data packet until the time set by the timer that starts at the same time as the transmission of the data packet expires.
