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:
predicting a future trajectory for the user device;
determining a reliability of the prediction; and
determining the candidate set of beams based on the predicted future trajectory and the determined reliability of the prediction,
wherein predicting the future trajectory comprises determining a speed of movement of the user device, and
wherein the method further comprises 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 the determined speed of movement of the user device.
