Abstract
A network may transmit either beam deployment information or beam number information to a user equipment (UE) carried on a train and configured for operation in the millimeter wave band. The deployment information may include deployment related distance parameters or azimuth angle spread parameters. The beam number information may indicate a number of network beams associated with a current cell. The UE may determine a number of UE receive beams based on deployment information or the network-indicated number of network beams. The UE may transmit feedback to the network, indicating the number of UE receive beams. Alternatively, the network may send a configuration message indicating a first number of UE receive beams to the UE, which the UE may treat as an upper bound or lower bound in its determination of a desired number of UE receive beams. The UE may transmit the desired number to the network.
