Communication devices and methods with beamforming training

A communication method for radio frequency (RF)-based communication by a communication device with another communication device, the communication method comprising:

• controlling, by beamforming circuitry of the communication device, antenna circuitry of the communication device to transmit and receive RF signals;
• and
• performing, by the beamforming circuitry, a beam transmission phase by controlling the antenna circuitry to:
• listen using a third receive beam while the another communication device transmits a first identifier of the another communication device subsequently using different first directive transmit beams;
• and
• set, once the first identifier has been received, a first directive transmit beam used for transmitting the first identifier as a second directive transmit beam indicated by first transmit beam information.

A communication device for radio frequency (RF)-based communication with another communication device, the communication device comprising:

• processing circuitry configured to:
• listen using a third receive beam while the another communication device transmits a first identifier of the another communication device subsequently using different first directive transmit beams;
• and
• set, once the first identifier has been received, a first directive transmit beam used for transmitting the first identifier as a second directive transmit beam indicated by first transmit beam information.
