SYSTEMS AND METHODS TO FACILITATE LOCATION DETERMINATION BY BEAMFORMING OF A POSITIONING REFERENCE SIGNAL - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240023059 titled 'SYSTEMS AND METHODS TO FACILITATE LOCATION DETERMINATION BY BEAMFORMING OF A POSITIONING REFERENCE SIGNAL
Simplified Explanation
The patent application describes techniques for positioning a mobile device in a wireless network using directional positioning reference signals (PRS) or beamforming. The method involves generating multiple directional PRS for at least one cell of a base station, where each PRS has unique signal characteristics and transmission direction. These directional PRS are then transmitted within the cell in their respective transmission directions. A mobile device can acquire and measure these directional PRS, which can be identified using their associated signal characteristics. The measurements can be used to assist in position methods such as OTDOA and ECID, as well as to mitigate multipath.

Original Abstract Submitted
techniques are provided for positioning of a mobile device in a wireless network using directional positioning reference signals (prs), also referred to as prs beamforming. in an example method, a plurality of directional prss are generated for at least one cell for a base station, such that each of the plurality of directional prss comprises at least one signal characteristic and a direction of transmission, either or both of which may be distinct or unique. the plurality of directional prss is transmitted within the at least one cell, such that each of the plurality of directional prss is transmitted in the direction of transmission. a mobile device may acquire and measure at least one of the directional prss which may be identified using the associated signal characteristic. the measurement may be used to assist position methods such as otdoa and ecid and to mitigate multipath.
