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. Depending on the figures of merit, an antenna array configuration is activated.

Abstract: At least one condition associated with radio communication of a radio device (10-A, 10-B-, 10-C, 100) with a further radio device (10-A, 10-B-, 10-C, 100) is monitored. In response to the at least one condition being met, full-duplex operation is activated for the radio communication of the radio device (10-A, 10-B-, 10-C, 100) with the further radio device (10-A, 10-B-, 10-C, 100). The full-duplex operation comprises transmission of a first signal on a carrier frequency from the radio device (10-A, 10-B-, 10-C, 100) to the further radio device (10-A, 10-B-, 10-C, 100) and simultaneous transmission of a second signal on the same carrier frequency from the further radio device (10-A, 10-B-, 10-C, 100) to the radio device (10-A, 10-B-, 10-C, 100).

Abstract: The present invention relates to a method for allocating radio resources in a wireless communication system (100). According to the method, at a base station (101), a first radio resource for a communication between the base station (101) and a relaying device (104) is determined. The relaying device (104) is configured to relay information between the base station (101) and at least one communication device (301) of the wireless communication system (100) located within a wireless communication range of the relaying device (104). Furthermore, a second radio resource for a communication between the relaying device (104) and the at least one communication device (301) is determined at the base station (101). A message (503) is transmitted from the base station (101) to the relaying device (104). The message (503) comprises information indicating the first radio resource and information indicating the second radio resource.
