Title:
METHOD AND DEVICE FOR CPE-BASED SIDELINK COMMUNICATION IN UNLICENSED SPECTRUM
Document Type and Number:
WIPO Patent Application WO/2024/076187
Kind Code:
A1
Abstract:
Provided are a method for a first device to communicate wirelessly and a device for supporting same. The method may comprise the steps of: acquiring information related to a plurality of cyclic prefix extension (CPE) starting candidate positions; selecting a CPE starting position from among the plurality of CPE starting candidate positions on the basis of the priority of sidelink (SL) transmission; and transmitting SL on the basis of the CPE starting position.
