Abstract
A method performed by a network node in a communication network is disclosed for controlling connectivity of a radio resource unit (RRU) to a baseband unit (BBU) in the communications network. The communication network comprises a plurality of RRUs and a plurality of BBUs, each RRU being connected to a BBU via a distribution network. The method comprises receiving information indicating that a connection of a first RRU to a first BBU is to be controlled and triggering a user equipment (UE) connected to the first RRU to perform measurements on signals from neighboring RRUs and to send a report of the performed measurements to the communications network. The method further comprises receiving the report of the performed measurements, and selecting a BBU, out of the plurality of BBUs, to which the first RRU is to be connected, based on the report of performed measurements and on information regarding to which of the plurality of BBUs the neighboring RRUs are connected.
