Abstract: The present invention relates to a method for operating a wireless communication system. The wireless communication system comprises a base station and a terminal. The terminal comprises a plurality of antenna elements and provides at least two antenna array configurations comprising a first antenna array configuration comprising at least two antenna elements having same radio transmission characteristics and a second antenna array configuration comprising at least two antenna elements having different radio transmission characteristics. According to the method, a selection process for selecting and an antenna array configuration of the at least two antenna array configurations is triggered and for each of the at least two antenna array configurations a corresponding figure of merit is determined. The corresponding figure of merit is determined based on corresponding pilot signals received from the base station via the corresponding antenna array configuration.

Abstract: A method for beam sweeping in a wireless communication system is described. Beam sweeping includes performing a reduced beam sweep corresponding to a reduced set of beams that are a subset of a full set of beams available for transmitting and/or receiving from an antenna module, without sweeping beams that are not members of the reduced set of beams. The method includes selecting a beam out of the reduced set of beams for transmitting and/or receiving from the antenna module based on the reduced beam sweep without sweeping beams that are not members of the reduced set of beams. Related devices are disclosed.
