Apparatuses, methods, and computer programs for a mobile transceiver and for a base station transceiver

An apparatus for a base station transceiver of a mobile communication system, the mobile communication system comprising the base station transceiver for communicating with a mobile transceiver, the apparatus comprising:

• a processor configured to generate a first configuration message, the first configuration message comprising information on a control region for the mobile transceiver, the control region indicating radio resources used by the base station transceiver to transmit a control message to the mobile transceiver on a control channel;
• wherein the processor is operable to generate a second configuration message, the second configuration message comprising information on a search space, the search space indicating a subset of radio resources of the control region, wherein the search space comprises a spatial radio resource;
• and
• a transmitter configured to transmit the first and the second configuration messages to the mobile transceiver.

A method for a mobile transceiver of a mobile communication system, the mobile communication system comprising a base station transceiver for communicating with the mobile transceiver, the mobile transceiver operating a plurality of antennas, the method comprising:

• receiving a first configuration message from the base station transceiver, the first configuration message comprising information on a control region for the mobile transceiver, the control region indicating radio resources used by the base station transceiver to transmit a control message to the mobile transceiver on a control channel;
• receiving a second configuration message from the base station transceiver, the second configuration message comprising information on a search space, the search space indicating a subset of radio resources of the control region, wherein the search space comprises a spatial radio resource;
• and
• controlling a reception of the control message on the control channel based on the information on the search space and the spatial resource using the plurality of antennas.
