Apparatus, system, and method of a transmit sector sweep (TXSS) procedure over a millimeterwave (mmWave) wireless communication channel

A product comprising one or more tangible computer-readable non-transitory storage media comprising instructions operable to, when executed by at least one processor, enable the at least one processor to cause an Access Point (AP) device to:

• transmit a trigger frame from a sub 10 Gigahertz (GHz) (sub-10 GHz) AP of the AP device over a sub-10 GHz wireless communication channel, the trigger frame configured to trigger a Transmit Sector Sweep (TXSS) procedure over a millimeterWave (mmWave) wireless communication channel, wherein the trigger frame comprises timing information to indicate a timing to initiate the TXSS procedure over the mmWave wireless communication channel;
• based on the trigger frame, transmit a sequence of sector sweep packets of the TXSS procedure from a mmWave AP of the AP device over the mmWave wireless communication channel;
• and
• process a feedback frame from a non-AP device to identify feedback information based on the sequence of sector sweep packets, the feedback frame received at the sub-10 GHz AP over the sub-10 GHz wireless communication channel after the TXSS procedure.

An apparatus comprising logic and circuitry configured to cause a non Access Point (AP) (non-AP) device to:

• process a trigger frame from an AP device, the trigger frame received at a sub 10 Gigahertz (GHz) (sub-10 GHz) non-AP STA of the non-AP device over a sub-10 GHz wireless communication channel, the trigger frame configured to trigger a Transmit Sector Sweep (TXSS) procedure over a millimeterWave (mmWave) wireless communication channel, wherein the trigger frame comprises timing information to indicate a timing to initiate the TXSS procedure over the mmWave wireless communication channel;
• based on the trigger frame, operate a mmWave non-AP STA of the non-AP device to receive from the AP device one or more sector sweep packets of a sequence of sector sweep packets of the TXSS procedure over the mmWave wireless communication channel;
• and
• transmit a feedback frame from the sub-10 GHz non-AP STA to the AP device over the sub-10 GHz wireless communication channel after the TXSS procedure, the feedback frame comprising feedback information based on the one or more sector sweep packets.

An apparatus comprising:

• means for processing, at a non Access Point (AP) (non-AP) device, a trigger frame from an AP device, the trigger frame received at a sub 10 Gigahertz (GHz) (sub-10 GHz) non-AP STA of the non-AP device over a sub-10 GHz wireless communication channel, the trigger frame configured to trigger a Transmit Sector Sweep (TXSS) procedure over a millimeterWave (mmWave) wireless communication channel, wherein the trigger frame comprises timing information to indicate a timing to initiate the TXSS procedure over the mmWave wireless communication channel;
• means for, based on the trigger frame, operating a mmWave non-AP STA of the non-AP device to receive from the AP device one or more sector sweep packets of a sequence of sector sweep packets of the TXSS procedure over the mmWave wireless communication channel;
• and
• means for causing the non-AP device to transmit a feedback frame from the sub-10 GHz non-AP STA to the AP device over the sub-10 GHz wireless communication channel after the TXSS procedure, the feedback frame comprising feedback information based on the one or more sector sweep packets.
