Title:
METHODS AND APPARATUS FOR ROUND-TRIP-TIME MEASUREMENT ON A SL INTERFACE CROSS-REFERENCE TO RELATED APPLICATIONS AND CLAIM OF PRIORITY
Document Type and Number:
WIPO Patent Application WO/2023/211257
Kind Code:
A1
Abstract:
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method of operating a user equipment (UE) is provided. The method includes receiving, from a second UE, a first sidelink (SL) positioning reference signal (PRS) in slot m; measuring a receive (Rx) timing of the first SL PRS in the slot m; and determining a reference transmit (Tx) timing of the slot m. The method further includes determining a first SL Rx - Tx time difference as a difference between the Rx timing of the first SL PRS in the slot m and the reference Tx timing of the slot m and determine information for a first report based on the first SL Rx - Tx time difference.
