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.

Embodiments described herein provide efficient beam pattern feedback from a user equipment (UE) to a receiving device to help reduce overhead of providing beam pattern information for position determination while maintaining high position determination accuracy. Embodiments include providing beam weights and template elemental game patterns, an elemental gain formula and parameters, and/or template beam patterns with boresight to a remote device, enabling the remote device to determine beam shape.

A system having a locator device and a plurality of tag devices is disclosed. The locator device comprises an antenna array allowing it to determine an angle of arrival for incoming signals from each of the plurality of tag devices. The system also defines a sequence of time slots, where each time slot has a specific function. The sequence may start with a locator time slot, where the locator device transmits a packet that informs all of the tag devices that this is the start of the sequence. A sync slot follows the locator time slot, where new tag devices may transmit a sync request to the locator device. Upon receipt of a sync request, the locator device assigns the new tag device a tag slot. Following the sync slot are a plurality of tag slots, where each tag device transmits an AoA packet during its assigned tag slot.
