Communication devices and methods for RF-based communication and position determination

A communication method for use by an initiator communication device for RF-based communication with a responder communication device, said communication method comprising:

• performing signaling to initiate a training phase, and
• controlling the initiator communication device to perform beamforming, in the training phase for determining an antenna weight vector (AWV) of a line of sight (LOS) path from the initiator communication device to the responder communication device by evaluating a time of flight of RF signals transmitted to the responder communication device.

A non-transitory, computer-readable storage medium for use by an initiator communication device for RF-based communication with a responder communication device, the non-transitory, computer-readable storage medium storing instructions that, when executed by circuitry of the initiator communication device, control the circuitry to perform a method comprising:

• performing signaling to initiate a training phase, and
• controlling the initiator communication device to perform beamforming in the training phase for determining an antenna weight vector (AWV) of a line of sight (LOS) path from the initiator communication device to the responder communication device by evaluating a time of flight of RF signals transmitted to the responder communication device.
