Abstract
An improved base station sharing in a radio communication system is disclosed. A logical base station is arranged to share a physical base station in the radio communication system with at least one further logical base station. According to an embodiment of the invention, the logical base station is associated with a control node and with an operation and maintenance node in the radio communication system, wherein the control node and the operation and maintenance node are separate from at least one further control node and at least one further operation and maintenance node being associated with the at least one further logical base station.
