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

A base station comprising:

• at least one processor;
• and
• at least one memory including computer program code, where the at least one memory and the computer program code are configured, with the at least one processor, to cause the base station to at least:
• configure a communication between the base station, a first user equipment to operate with a first system bandwidth and a second user equipment 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,
• provide first common channels or signals within the first system bandwidth and provide second common channels or signals within the second system bandwidth;
• configure part of the first common channels or signals and part of the second common channels or signals to share at least one common symbol and reduce at least a control channel overhead of the cellular network system, wherein the configured part of the first common channels or signals and the configured part of the second common channels or signals are superpositioned on top of each other on the shared at least one common symbol to be used by the first user equipment and the second user equipment;
• configure at least one of the common channels or signals of the part of the first common channels or signals to be used for the communication by the first user equipment and the second user equipment;
• and
• allow transmission on the second common channels or signals within a predefined duty cycle, wherein the predefined duty cycle allows transmission of the communication in only a predefined subset of all subframes of the communication.
