Title:
METHOD AND APPARATUS FOR DOWNLINK AND UPLINK CARRIER-PHASE REPORTING
Document Type and Number:
WIPO Patent Application WO/2023/211072
Kind Code:
A1
Abstract:
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Apparatuses and methods for an uplink carrier-phase reporting. A method of operating a user equipment (UE) includes receiving, from N antennas of a base station, N downlink (DL) positioning reference signals (PRSs), respectively, and measuring carrier phase differences of the received DL PRSs corresponding to adjacent pairs of the N antennas. The DL PRSs are received in orthogonal resources and N>1. The method further includes determining a first carrier phase difference to report based on the measured carrier phase differences and reporting the first carrier phase difference to a network.
