Positioning assisted initial beamforming

Abstract

The devices, systems, and methods described herein are directed towards a base station determining an initial beam, based on a location of a user equipment (UE) device, over which to transmit a Synchronization Signal Block (SSB) signal. In some examples, the base station determines, based on the location of the UE device, an initial estimate of at least one characteristic of a multiple-input, single-output (MISO) channel, where the MISO channel is characterized by a vector between the base station and the UE device. The base station applies a precoder, which is based on the initial estimate of the at least one characteristic of the MISO channel, to an SSB signal to determine the initial beam on which to transmit the SSB signal. The base station transmits the SSB signal to the UE device via the initial beam and can subsequently refine the beamforming process based on UE device feedback.
