Abstract
A radio network node () is configured to serve a wireless device () in a wireless communication system (). The radio network node () in this regard is configured to determine that the wireless device () is onboard a public transit vehicle (). Based on that determination, the radio network node () is configured to predict a position of the public transit vehicle (), e.g., based on a route schedule () of the public transit vehicle () and/or positioning measurements () received from the public transit vehicle (). The radio network node () is further configured to control beamforming for the wireless device () based on the predicted position of the public transit vehicle (). In some embodiments, this controlling comprises performing dynamic beam direction adjustment, as needed to track the vehicle ()'s movement. Alternatively or additionally, the controlling comprises performing beam selection from among a subset of candidate beams with coverage in a vicinity of the vehicle ()'s predicted position.
