Abstract: Disclosed is a method comprising transmitting a beam switch request from a first distributed unit to a second distributed unit. The first distributed unit then receives a beam switch acknowledgment from the second distributed unit. The first distributed unit transmits a beam switch notification to a central unit, wherein the first distributed unit and the second distributed unit are at least partly controlled by the central unit. The first distributed unit further transmits a beam switch command to a terminal device.
