Numerology-dependent downlink control channel mapping

A method implemented in a base station, BS, comprising:

• transmitting system information indicating a current numerology of a control region with configurable numerology;
• generating a signal using a channel mapping selected from channel mappings;
• and
• transmitting the generated signal in the control region,
• wherein the channel mapping is selected on the basis of the current numerology of the control region or vice versa.

A user equipment comprising:

• a processor;
• a communication interface;
• and
• a computer program product storing instructions that, when executed by the processor, cause the UE to:
• receive system information indicating a current numerology of a control region with configurable numerology;
• and
• decode the control region in accordance with a channel mapping which is selected channel mappings on the basis of the current numerology.
