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： 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.
