Abstract
A network interface device generates a packet that includes a beacon frame for transmission in a superframe. The beacon frame is used to announce the presence of a network and also is formatted as a beamforming training (BFT) frame to permit other communication devices to perform beamforming training with the packet. The beacon frame is generated to include (i) a frame control field, (ii) a duration field, (iii) a timestamp field, (iv) information indicative of a time of a subsequent association beamforming training (A-BFT) time slot, and (v) beamforming training information, which includes a countdown field. The network interface device transmits the packet during a beacon timeslot of the superframe, which is separate from an association beamforming training (A-BFT) timeslot of the superframe.
