1. A method for wireless communication, wherein an access node is configured to transmit signals using beamforming to a user device, wherein transmitting signals using beamforming comprises transmitting signals using a selected beam of a plurality of available beams, and wherein beam tracking comprises measurements by the user device on a candidate set of beams of the plurality of available beams for beam selection, the method comprising:
acquiring at least one of an estimate of a distance from the access node to the user device and an estimate of a velocity parameter of the user device; and
adjusting one or more of a beam tracking measurement frequency, a beam tracking measurement periodicity, a beam tracking measurement period, and a beam tracking measurement interval based on at least one of the estimated distance from the access node to the user device and the estimated velocity parameter of the user device.
