Title:
METHOD AND DEVICE FOR APERIODIC DATA TRANSMISSION IN SIDELINK COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2021/029530
Kind Code:
A1
Abstract:
A method and a device for aperiodic data transmission in sidelink communication are disclosed. An operating method of a first terminal comprises the steps of: transmitting, to a base station, a request message requesting the allocation of sidelink resources for aperiodic data; receiving, from the base station, first CG configuration information that includes first resource allocation information indicating the sidelink resources; checking the sidelink resources indicated by the first resource allocation information; and, when the aperiodic data is generated, transmitting, to a second terminal, the aperiodic data in a first transmission period comprising the sidelink resources. Therefore, the performance of a communication system can be improved.
