  • Patent number: 9992741
    Abstract: Devices and methods of limiting wideband STA communication are generally described. The STA receives, over a primary channel, a wakeup frame containing an indication of a SP or CBAP to acquire a wideband TXOP over a wide bandwidth channel including the primary channel and a secondary channel and a control trailer having an indication of the wide bandwidth channel. Prior to the SP/CBAP, the STA opens reception from the primary channel to the wide bandwidth channel. The STA then communicates with another STA over the wide bandwidth channel and subsequently reduces reception from the wide bandwidth channel to the primary channel. The wakeup frame originates from an AP/PCP or the other STA, and contains fields indicating the wakeup frame length and SP or a sensing time length prior to the CBAP.

  • Publication number: 20180091281
    Abstract: In Down Link MU-MIMO, an AP transmits to several STAs concurrently. In the mmWave band, directional transmissions are used so it is necessary for both the AP and the STAs to set their antenna arrays (by setting their antenna weight vectors—AWVs) in the best way to receive the transmissions directed to them by the AP and to avoid interference from transmissions directed to other devices. An exemplary embodiment discloses a beamforming training protocol that is capable of generating a set of antenna weight vectors for MU-MIMO operation that at least improves performance of subsequent communications.
