Title:
METHOD AND APPARATUS FOR ROUND-TRIP CARRIER-PHASE OPERATION IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/019515
Kind Code:
A1
Abstract:
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Methods and apparatuses for round-trip carrier-phase operation in a wireless communication system. A method of operating a user equipment (UE) includes receiving, from a first transmit receive point (TRP), a first downlink (DL) position reference signal (PRS) and measuring a first carrier phase associated with a center frequency of the first DL PRS. The method further includes including, in a measurement report, (i) a carrier phase measurement based on the measurement of the first carrier phase and (ii) a DL reference signal time difference (RSTD) measurement or a UE receive-transmit time difference measurement and transmitting the measurement report.
