More Information
Summary:An operation method of a terminal in a non-terrestrial network may comprise when a transmission operation of downlink data is started in an on-duration according to a discontinuous reception (DRX) cycle, starting a first timer indicating a first time interval required for a retransmission operation of the downlink data; starting a second timer when the first timer expires; performing a downlink monitoring operation in a second time interval according to the second timer; and when control information for the retransmission operation is received from a non-terrestrial node in the second time interval, receiving the downlink data from the non-terrestrial node in a downlink resource indicated by the control information, wherein the first timer is configured in consideration of a transmission delay between the non-terrestrial node and the terminal.
