Title:
APPARATUSES AND METHODS OF MEASURING AND REPORTING CARRIER PHASE OF MULTI-PATH CHANNELS
Document Type and Number:
WIPO Patent Application WO/2024/055938
Kind Code:
A1
Abstract:
A method of measuring and reporting carrier phase of multi-path channels includes measuring, by a user equipment (UE), carrier phases of multiple paths of a downlink positioning reference signal (DL PRS) and reporting, by the UE, a carrier phase measurement of the multiple paths of the DL PRS. Another method of measuring and reporting carrier phase of multi-path channels includes measuring, by a transmission/reception point (TRP), carrier phases of multiple paths of a sounding reference signal (SRS) and reporting, by the TRP, a carrier phase measurement of the multiple paths of the SRS.
