MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202548013581 A) filed by Qualcomm Incorporated on February 17, 2025, for Method And Apparatus For 5g Positioning Accuracy Improvement In Presence Of Phase Noise.
Inventors include Kumar, Mukesh; and Opshaug, Guttorm Ringstad.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: A mobile device and base station are enabled to support improved positioning accuracy in the presence of phase noise in high frequency radio network, such as in 5G New Radio network operating in mmWave. Phase Tracking Reference Signal (PTRS) may be transmitted with Positioning Reference Signals (PRS) and used for positioning and/or used to correct the phase offset between symbols in the PRS. A request may be made to transmit PTRS alone or with the PRS, or that the PRS is transmitted with a specific PRS frame structure, e.g., with a specific comb value, that minimizes the impact of phase noise. The PTRS or a phase ramp of the staggered symbols in the PRS may be used to estimate and correct the phase offset. Less than all of the symbols transmitted in the PRS may be used to generate positioning measurements to minimize the impact of phase noise.
