Summary:Methods and apparatus relate to cellular communications and in particular to a frequency spectrum shared by two cellular networks. An object is flexible utilization of the spectrum. This is achieved by a method where a first of the networks occupies part of the shared spectrum in relation to the traffic load in the first network. The first network informs a second of the networks on the extent the shared spectrum is occupied, for the second network to be free to use the shared spectrum outside the occupied part. A radio resource management unit, a base station controller, and a radio base station are also disclosed. An advantage is that spectrum can be lent from an old system when a new system is introduced.
