Abstract: A communication device, e.g. an access point, for RF-based communication with another communication device, e.g. a station, comprises antenna circuitry configured to transmit and receive RF signals and beamforming circuitry configured to perform beamforming. The beamforming circuitry controls the antenna circuitry to transmit data, in a beacon transmission phase prior to the beamforming training phase, using a set of third directive transmit beams in subsequent time slots and to listen, in the beamforming training phase, using a set of first directive receive beams in subsequent time slots that is different from the set of third directive transmit beams.

Abstract: A communication device and method are presented that support the use of both uniform and non-uniform constellations and provide a reasonable solution for signaling. Capability information is transmitted, said capability information indicating if non-uniform transmission constellations are supported by the mapping circuitry on the transmitter side and/or if non-uniform reception constellations are supported by the demapping circuitry on the receiver side.
