The position of a mobile device is estimated using angle based positioning measurements. The angle based positioning measurements are generated using transmit (Tx) beams or receive (Rx) beams from one or more base stations that generate the beams over an ultra-wide bandwidth, which produces frequency and spatial distortions and impairments in an array gain response. The array gain distribution variation as a function of angle and frequency for the set of beam weights used in beamforming is conveyed to indicate the frequency and spatial distortions. The array gain distribution variation may be provided to the mobile device in assistance data for a sub-band that is only a portion of the allocated bandwidth for the base stations, or as an aggregation of the array gain distribution variation for a plurality of sub-bands of the allocated bandwidth to reduce the overhead in signaling.

A system and method for estimating a geolocation The method includes subdividing the camping cell into grid points where each grid point of the grid points has an associated relative offset from a camping beam center; illuminating the camping cell with a camping beam and each of the adjacent cells with adjacent beams; receiving a camping beam signal strength and adjacent beams signal strengths for each grid point of the grid points; profiling, at each grid point of the grid points, ratios of the camping beam signal strength to each one of the adjacent beams signal strengths; mapping the ratios and the associated relative offset of each grid point of the grid points; and estimating a relative geolocation of a User Terminal (UT) from the camping beam center based on a UT camping beam signal strength and UT adjacent beams signal strengths.

This disclosure provides methods, devices, and systems for multi-level configuration and reporting for positioning in new radio (NR) wireless communications systems. In some wireless communications systems, a network entity may determine a position or location of a supported user equipment (UE) using radio access network information. The information may be associated with UE-assisted positioning techniques, such as a positioning reference signal (PRS) transmission by the base station and reporting of radio signaling measurements by the UE. The UE may support a multi-level configuration for reporting the radio signaling measurements, including determined report quantities on one or more of a resource level, a set level, or a setting level for the PRS transmission, or generally for the network entity. The described techniques may improve robustness associated with the reporting and, in some examples, reduce signaling overhead associated with determining a positioning and location of the UE.

A system comprising: a transmitting device configured to transmit, in at least one plane, a plurality of directional signals each covering an angular sector, wherein every adjacent pair of said angular sectors overlaps partially to create a logical sector, and wherein each of said plurality of directional signals encodes at least an indication regarding each said logical sector associated therewith; and a client device comprising program instructions executable by at least one hardware processor to: cause the client device to receive at least some of said plurality of directional signals, calculate a signal strength level (RSL) value for each of said received directional signals, and determine that said client device is located within a said logical sector, when two highest said RSL values (i) are related to two said directional signals associated with said logical sector, and (ii) are within a specified value range of each other.
