Abstract: A method for reducing power consumption of a terminal that communicates with a base station in a mobile communication system using a multi-carrier structure composed of a primary component carrier and at least one secondary component carrier comprises: receiving a discontinuous reception (DRX) parameter group for multi carriers from the base station; and setting the multi carriers to the same parameter value, by using the received parameter group. The method for reducing power consumption of the terminal further comprises: performing a downlink control channel receive operation on each carrier according to a DRX cycle. As the base station in the mobile communication system using the multi-carrier structure simplifies the DRX process for reducing power consumption of a terminal by reducing signaling load for the multi-carrier control of the terminal, it becomes possible to reduce power consumption of the terminal.

Abstract: 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.

Abstract: Disclosed are operation methods of communication node supporting direct communications in network. The operation method may comprise generating control information which includes parameters used for transmitting and receiving data; transmitting, to a second UE, the control information through a physical sidelink control channel (PSCCH); and transmitting, to the second UE, the data through a physical sidelink shared channel (PSSCH) based on the parameters. Therefore, a performance of the network can be enhanced.
