Title:
METHOD AND APPARATUS FOR PERFORMING DCI BASED SIDELINK COMMUNICATION IN NR V2X
Document Type and Number:
WIPO Patent Application WO/2021/101329
Kind Code:
A1
Abstract:
According to one embodiment of the present disclosure, provided is a method by which a first device performs sidelink communication. The method comprises the steps of: receiving a first DCI including information on a resource for LTE sidelink communication of the first device through a PDCCH from an NR base station; transmitting an SCI to a second device through a PSCCH on the basis of the resource; and transmitting data to the second device through a PSSCH related to the PSCCH, wherein the size of the first DCI can be adjusted from the size of a second DCI to the size of the first DCI, on the basis of the size of the first DCI that is obtained by the NR base station through at least one second DCI different from the first DCI.
