Techniques using a first band of communication to synchronize beamforming for a second band of communication

At least one non-transitory computer-readable storage medium comprising instructions that when executed cause processing circuitry to:

• send an indication in a first frequency band of communication, the indication to indicate a capability to communicate in a second frequency band of communication;
• send beamforming information for the second frequency band of communication in the first frequency band of communication;
• send a synchronization packet in the first frequency band of communication, the synchronization packet comprising a preamble, a header, and data;
• and
• perform a beamforming operation for the second frequency band of communication using the beamforming information communicated in the first frequency band of communication, the beamforming operation comprising sending a training sequence of a training packet on the second frequency band after a delay time, wherein the delay time is time between conclusion of the preamble of the synchronization packet and start of the training sequence of the training packet, and wherein the first frequency band of communication comprising a lower band of communication in at least one of a 2.4 gigahertz (GHz) band and a 5 GHz band, and the second frequency band of communication comprising a higher band of communication in a 60 GHz band.

An apparatus, comprising:

• one or more transceivers;
• circuitry coupled to the one or more transceiver, the circuitry to:
• send, via one of the one or more transceivers, an indication in a first frequency band of communication, the indication sent in a probe request and to indicate a capability to communicate in a second frequency band of communication,
• send, via one of the one or more transceivers, beamforming information for the second frequency band of communication in the first frequency band of communication, the beamforming information comprising information based on beamforming for the first frequency band of communication,
• send a synchronization packet in the first frequency band of communication, the synchronization packet comprising a preamble, a header, and data, and
• perform a beamforming operation for the second frequency band of communication using the beamforming information communicated in the first frequency band of communication, the beamforming operation comprising sending a training sequence of a training packet on the second frequency band after a delay time, wherein the delay time is time between conclusion of the preamble of the synchronization packet and start of the training sequence of the training packet, and wherein the first frequency band of communication comprising a lower band of communication in at least one of a 2.4 gigahertz (GHz) band and a 5 GHz band, and the second frequency band of communication comprising a higher band of communication in a 60 GHz band.
