METHOD AND APPARATUS FOR USER EQUIPMENT IN BATTERY SAVING MODE TRANSMITTING REVERSE DIRECTION CONTROL SIGNAL IN MOBILE COMMUNICATION SYSTEM

摘要

The present disclosure relates to a method and apparatus for a user equipment to transmit control signals to a base station in a wireless communication system supporting discontinuous reception (DRX). In particular, the method for a user equipment to transmit control signals to a base station includes: receiving a downlink control channel indicating new uplink or downlink transmission in a first period preset with reference to the last subframe of an active time; and selectively skipping transmission of a control signal in a preset second period starting from a subframe at which the downlink control channel is received. In addition, a user equipment transmitting control signals to a base station includes: a transceiver unit to send and receive signals to and from the base station; and a control unit determining, when a downlink control channel indicating new uplink or downlink transmission is received by the transceiver unit in a first period preset with reference to the last subframe of an active time, whether to selectively transmit a control signal in a preset second period starting from a subframe at which the downlink control channel is received.
