Doppler shift or doppler spread as input for beam-switching or node-switching in wireless networks

摘要

Techniques in a node of a wireless communications network, where one or more wireless devices are served via beams transmitted by network nodes. An example method comprises estimating (910), for a wireless device operating in the wireless communications network, a Doppler shift associated with movement of the wireless device, or a Doppler spread associated with movement of the wireless device, or both. The method further comprises, based on said estimating, evaluating (920) a change in estimated Doppler shift associated with the wireless device or evaluating the estimated Doppler spread associated with the wireless device, or both, and adjusting (930) at least one mobility-related parameter, based on said evaluating of the change in estimated Doppler or the evaluating of the estimated Doppler spread, or both. The method further comprises carrying (940) out one or more mobility procedures for the wireless device, based on the adjusted at least one mobility-related parameter.
