Abstract

Embodiments provide apparatuses, methods and a computer programs for a base station transceiver and a mobile transceiver. An apparatus ( 10 ) operable in a base station transceiver ( 100 ) of a mobile communication system comprises a transceiver module ( 12 ), which comprises interfaces to a plurality ( 18 ) of antennas, and which is operable to transmit radio signals using combinations of time and frequency radio resources. The transceiver module ( 12 ) is further operable to form a first set of beam patterns ( 16 ) using the plurality of antennas. The first set of beam patterns ( 16 ) comprises two or more spatially differing beam patterns. The base station transceiver apparatus(10) comprises a control module ( 14 ), which is operable to control the transceiver module and to transmit a common control signal for a plurality of mobile transceivers ( 200 ) using the beam patterns of the set of first beam patterns ( 16 ) on the same time and frequency radio resource. An apparatus ( 20 ) operable in a mobile transceiver ( 200 ) of a mobile communication system comprises a transceiver module ( 22 ), which is operable to receive radio signals using combinations of time and frequency radio resources. The mobile transceiver apparatus ( 20 ) comprises a control module ( 24 ) operable to control the transceiver module ( 22 ). The control module ( 24 ) is operable to receive a common control signal from a base station transceiver ( 100 ) using different time and frequency resources, to determine a time and frequency resource, which provides the common control signal with a highest quality, and to determine information related to at least one beam pattern used on the time and frequency resource providing the common control signal with the highest quality. The control module ( 24 ) is operable to transmit a signal comprising the information related to the at least one beam pattern to the base station transceiver ( 100 ).
