Abstract

Embodiments provide beamforming 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) comprising interfaces to a plurality (15) of antennas. The transceiver module (12) is operable to subdivide the plurality (15) of antennas in a plurality of subgroups using the interfaces, and to form a first beam pattern (16) using one or more antennas of a subgroup. The apparatus (10) further comprises a control module (14), which is operable to transmit a synchronization signal using the transceiver module (12) and the first beam pattern (16). The control module (14) is further operable to receive a response signal after transmission of the synchronization signal from a mobile transceiver (200) using the transceiver module (12), to determine a second beam pattern (18) based on the response signal from the mobile transceiver (200). The second beam pattern (18) has a higher antenna gain than the first beam pattern (16), and to transmit a signal to the mobile transceiver (200) using the second beam pattern (18) and the t…
