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.
