Title:
EFFICIENT POSITIONING REFERECE SIGNAL DETECTION FOR SIDELINK POSITIONING IN UNLICENSED SPECTRUM
Document Type and Number:
WIPO Patent Application WO/2024/031408
Kind Code:
A1
Abstract:
Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable media supporting efficient positioning reference signal detection for sidelink positioning in an unlicensed spectrum. A first terminal device in a radio access network may be configured to initiate a first listen before talk procedure before transmitting a sidelink positioning reference signal to a second terminal device in the radio access network in an unlicensed spectrum during a sidelink positioning session, transmit positioning related control information to the second terminal device in a licensed spectrum, and transmit the sidelink positioning reference signal in the unlicensed spectrum in response to the first listen before talk procedure ending successfully. The positioning related control information comprises an indication for the second terminal device to receive a notification of whether the first listen before talk procedure is successful or to perform a second listen before talk procedure.
