Title:
METHODS AND APPARATUSES FOR TRANSMISSION OVER UNLICENSED SPECTRA
Document Type and Number:
WIPO Patent Application WO/2024/074043
Kind Code:
A1
Abstract:
Embodiments of the present disclosure relate to methods and apparatuses for transmission over unlicensed spectra. According to an embodiment of the present disclosure, a user equipment can include: a transceiver; and a processor coupled to the transceiver and configured to: determine an operation with respect to a sidelink synchronization signal block (S-SSB) occasion according to one of the followings: whether it can be determined that the S-SSB occasion overlaps with a channel occupancy time (COT) for an SL transmission; or whether there is other radio access technology in an unlicensed spectrum associated with the S-SSB occasion; and perform the operation with respect to the S-SSB occasion based on the determination.
