Abstract

A communication device for RF-based communication with another communication device. The communication device comprising antenna circuitry configured to transmit and receive RF signals and beamforming circuitry configured to perform beamforming and to control the antenna circuitry in a beamforming training phase to transmit and/or receive RF signals using one or more selected directive beams. The beamforming circuitry is configured to perform beamforming training by controlling the antenna circuitry i) to transmit data using at least one first directive transmit beam, wherein the other communication device is configured to listen using a first directive receive beam, said data including a second transmit beam information, and ii) to subsequently listen using a predetermined second directive receive beam for a response from the other communication device.
