Communication device incorporating beamforming handshaking

A communication device comprises:

• a wireless transmitter;
• a wireless receiver;
• and
• a processing module operably coupled to the wireless transmitter and the wireless receiver, wherein at least one of the wireless transmitter, the wireless receiver, and the processing module is operably coupled to facilitate:
• transmission of a plurality of control-level wireless signals in different sectors of a transmission radiation pattern;
• a determination of whether a response wireless signal is received regarding at least one of the plurality of control-level wireless signals from another communication device;
• when the response signal is received:
• a handshake communication with the other communication device to determine adjustments of at least one of transmit beamforming parameters and receive beamforming parameters to produce at least one of adjusted transmit beamforming parameters and adjusted receive beamforming parameters;
• and
• a normal-level communication with the other communication device using the at least one of the adjusted transmit beamforming parameters and the adjusted receive beamforming parameters.

A communication device comprises:

• a wireless transmitter;
• a wireless receiver;
• and
• a processing module operably coupled to the wireless transmitter and the wireless receiver, wherein at least one of the wireless transmitter, the wireless receiver, and the processing module is operably coupled to facilitate a beamforming adjustment handshake that includes:
• the processing module generating a request frame that includes a beamforming refine control field;
• the wireless transmitter:
• converting the request frame into an outbound wireless signal;
• and
• transmitting the outbound wireless signal;
• the wireless receiver:
• receiving an inbound wireless signal;
• and
• converting the inbound wireless signal into a response frame that identifies the other communication device and a response message;
• and
• the processing module processing the response frame to determine adjustments of at least one of receive beamforming parameters and transmit beamforming parameters.
