摘要： An operation method of a first terminal in a communication system is provided. The method includes transmitting, to a base station, a configuration request message requesting configuration of a sidelink (SL) bandwidth part (BWP) used for sidelink communication between the first terminal and a second terminal. A configuration information message is received including configuration information of the SL BWP from the base station. The sidelink communication is performed with the second terminal using one or more SL BWPs indicated by the configuration information and in response to determining that reconfiguration of the one or more SL BWPs is necessary, a reconfiguration request message is transmitted to the base station.

摘要： Disclosed is a resource allocation method in sidelink communication. An operation method of a terminal includes the steps of: receiving a first message, including mobility conditions to be used for selecting a resource allocation mode for sidelink communication, from a base station; selecting the resource allocation mode to be applied to the terminal, the selection being made on the basis of the results of a comparison between the mobility of the terminal and the mobility conditions; determining a resource pool on the basis of the selected resource allocation mode; and performing the sidelink communication by using the determined resource pool. Accordingly, the performance of a communication system can be enhanced.

摘要： Disclosed are a method and a device for sidelink groupcast communication. A method for operating a transmitting terminal comprises the steps of: transmitting an SS/PBCH block for sidelink communication in all directions by using a beam sweeping method; receiving, from a plurality of receiving terminals, first feedback information about the SS/PBCH block; and transmitting a sidelink channel in a specific direction by using beams of the transmitting terminal that are determined on the basis of the first feedback information. Therefore, communication system performance can be improved.

摘要： A method and a device for handover in an EFB-based non-terrestrial network are provided. The method may be performed in a first cell of a first satellite. The method includes performing a connection configuration procedure with a UE. The method also includes, after performing the connection configuration procedure, decreasing a value of a cell service timer, that indicates the time at which a communication service can be provided in the first cell, according to a decrement interval. The method additionally includes, in response to determining that the cell service timer is below a threshold, triggering a handover procedure.

摘要： A method and a device for handover in an earth-moving beam (EMB)-based non-terrestrial network are disclosed. A method of a user equipment (UE) comprises the steps of: receiving, from a first cell of a satellite, first handover configuration information including information about a first cell service timer indicating the time at which a communication service can be provided in the first cell; reducing the first cell service timer according to a first reduction interval; and triggering an intra-satellite (intra-SAT) handover procedure if the first cell service timer has a first critical value or less.

摘要： A method and a device may perform resource sensing and selection for one or more links in a communication system supporting a DRX operation. A method for operation of a first terminal includes configuring a first link between the first terminal and a first communication node. The method also include configuring a second link between the first terminal and a second communication node. The method further includes identifying the overlapped interval between a first on-duration interval following a first DRX configuration in the first link and a second on-duration interval following a second DRX configuration in the second link. The method additionally includes performing a reception operation in the overlapped interval on the basis of one or more DRX configurations among the first DRX configuration and the second DRX configuration.
