Extending association beamforming training

An apparatus of an enhanced directional multi-gigabit (EDMG) station comprising:

• memory;
• and processing circuitry coupled to the memory, the processing circuitry configured to:
• decode a directional multi-gigabit (DMG) beacon, the DMG beacon comprising an association beamforming training (A-BFT) length subfield and an A-BFT multiplier subfield, wherein the EMG beacon is received within a beacon transmission interval (BTI), and wherein a A-BFT access period follows the BTI;
• determine a number of SSW slots contained in the A-BFT access period as an A-BFT length indicated by the A-BFT length subfield times (×) (1+an A-BFT multiplier indicated by the A-BFT multiplier field);
• and
• configure the EDMG station to transmit a SSW frame within one of the number of SSW slots contained in the A-BFT access period.

A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors of an enhanced directional multi-gigabit (EDMG) station, the instructions to configure the one or more processors to:

• decode a directional multi-gigabit (DMG) beacon, the DMG beacon comprising an association beamforming training (A-BFT) length subfield and an A-BFT multiplier subfield, wherein the EMG beacon is received within a beacon transmission interval (BTI), and wherein a A-BFT access period follows the BTI;
• determine a number of SSW slots contained in the A-BFT access period as an A-BFT length indicated by the A-BFT length subfield times (×) (1+an A-BFT multiplier indicated by the A-BFT multiplier field);
• and
• configure the EDMG station to transmit a SSW frame within one of the number of SSW slots contained in the A-BFT access period.

An apparatus of an enhanced directional multi-gigabit (EDMG) access point comprising:

• memory;
• and processing circuitry coupled to the memory, the processing circuitry configured to:
• encode a directional multi-gigabit (DMG) beacon, the DMG beacon comprising a duration field, an association beamforming training (A-BFT) length subfield, and an A-BFT multiplier subfield, the A-BFT length subfield and the A-BFT multiplier subfield indicating a number of sector sweep (SSW) slots contained in an A-BFT;
• configure the EDMG access point to transmit the DMG beacon to an EDMG station;
• determine the number of SSW slots as an A-BFT length indicated by the A-BFT length subfield times (×) (1+an A-BFT multiplier indicated by the A-BFT multiplier field);
• and
• decode an SSW frame from the EDMG station within a SSW slot of the number of SSW slots.
