Configuring a communication with user equipments operating with a different system bandwidth

A base station for configuring a communication between the base station, a first user equipment being adapted to operate with a first system bandwidth and a second user equipment being adapted to operate with a second system bandwidth, wherein the first system bandwidth is broader than the second system bandwidth and wherein the base station, the first user equipment and the second user equipment are located within a cellular network system,

• the base station comprising
• a control unit being adapted to provide first common channels or signals within the first system bandwidth and to provide second common channels or signals within the second system bandwidth, wherein a part of the first common channels or signals and a part of the second common channels or signals are superpositioned, and
• a configuration unit being adapted to configure at least one of the common channels or signals of the part of the first common channels or signals to be used by the first user equipment and the second user equipment.
