Beam tracking for periodic user equipment movement
Abstract:
Methods, systems, and devices for wireless communications are described techniques provide for the identification of a sequence of beamforming parameters that are used for communications between a user equipment (UE) and a base station using a sequence of transmission beams. A UE may measure received reference signals that are transmitted in a series of downlink transmission beams from a base station, and report measurement parameters associated with the downlink transmission beams to the base station as part of a beam tracking and beam refinement procedure. The base station may provide transmission configuration indicator (TCI) states that are associated with each transmission beam. The TCI states may be recorded over a course of a periodic movement of the UE, and may be used deterministically to identify beamforming parameters for transmission and reception of a subsequent series of downlink transmission beams when the UE makes a subsequent same periodic movement.
