Abstract: A network node (18) identifies radio beams (50) that are affected by periodic fading at a User Equipment (UE) (12) and penalizes the identified beams (50) with respect to a serving-beam selection procedure that is used to select a serving radio beam (60) for the UE (12). For example, among a set (52) of radio beams (50) that are candidates for serving the UE (12), the serving-beam selection procedure selects one or more of the candidate beams (50) according to rankings determined from radio-signal measurements reported by the UE (12) or from measurements on Sounding Reference Signals (SRS) transmitted by the UE (12). In this context, penalizing a beam (50) means discounting its ranking for purposes of considering it within the beam-selection procedure.
