A mobile communication system (300) comprises one or more relay station transceivers (100) being configured, to provide wireless services to one or more mobile transceivers (200) of the mobile communication system (300) via a first radio channel. The one or more relay station transceivers (100) are configured to use wireless backhaul communication to communicate with a central, unit (400) of the mobile communication system (300) via a second radio channel. An apparatus (10) for determining information related to precoding in the mobile communication system (300) comprises one or more interfaces (12) configured to obtain, information related to the first radio channel or an. effective access channel, and to obtain information related to the second radio channel. The apparatus (10) further comprises a control module (14) configured to determine the information related to the precoding based on the information related to the first radio channel or the effective access channel, and based on the information related to the second radio channel.

    Abstract: Embodiments provide an apparatus, a method and a computer program for the transceiver of a mobile communication system. The apparatus (10) is operable in a first transceiver (100) of a mobile communication system. The apparatus (10) comprises a transceiver module (12) comprising interfaces to a plurality of transmit antennas (15). The transceiver module (12) is operable to subdivide the plurality of transmit antennas (15) in a plurality of subgroups using the interfaces, and to form a set of first beam patterns (16) using one or more transmit antennas of a subgroup. The apparatus (10) further comprises a control module (14) operable to determine information related to a quality of a radio link between the first transceiver (100) and the second transceiver (200). The control module (14) is further operable to determine a second beam pattern (18) for communicating with the second transceiver (200) using two or more beam patterns from the set of first beam patterns (16). A number of first beam patterns used to determine the second beam pattern (18) is based on the information related to the quality of the radio link between the first transceiver (100) and the second transceiver (200). The control module (14) is further operable to communicate with the second transceiver (200) using the second beam pattern (18) and the transceiver module (12).
