Abstract:
Apparatuses, systems, and methods that enable native MAC support of beamforming are contemplated. An embodiment may comprise a mobile computing device, such as a laptop, with wireless communications capabilities, such as an integrated wireless networking card. The networking card of the laptop may transmit and receive various types of frame data using one or more beamforming techniques. Upon establishing a link with another wireless device, the laptop may sense that the link quality is degrading. Instead of having to reestablish a new link using dedicated BF frames and the conventional BF protocol, embodiments described herein may instead transmit beamforming information in various types of frames which enable the wireless communication devices to adjust the beamforming parameters in a more efficient manner. For example, the devices may include beamforming information in control frames and data frames and transmit the frames in a sweeping sector fashion.
