Abstract
A method for beamforming training and a device using the same are provided. The device receives, from an access point (AP), a plurality of beacon frames for a sector sweep at a beacon transmission interval (BTI). At least one of the plurality of beacon frames includes an overload indicator indicating an overload state. The device determines whether to initiate a random backoff in an association beamforming training (A-BFT) following the BTI, on the basis of the overload indicator.
Claims13
A method for performing beamforming training in a wireless local area network, the method comprising:
- receiving, by a station (STA), a plurality of beacon frames for sector sweep in a beacon transmission interval (BTI) from an access point (AP), wherein at least one beacon frame of the plurality of beacon frames includes overload information which indicates an overload state;
- and
- determining, by the STA, whether to invoke a random backoff in an association-beamforming training (A-BFT) following the BTI based on the overload information.
A device for performing beamforming training in a wireless local area network, the device comprising:
- a transceiver configured to transmit and receive a radio signal;
- and
- a processor connected to the transceiver and configured to:
- receive a plurality of beacon frames for sector sweep in a beacon transmission interval (BTI) from an access point (AP), wherein at least one beacon frame of the plurality of beacon frames includes overload information which indicates an overload state;
- and
- determine whether to invoke a random backoff in an association-beamforming training (A-BFT) following the BTI based on the overload information.
