Latest Patents
One of his latest patents is titled "Sounding for trigger-based ranging." This patent provides methods, components, devices, and systems for sounding in trigger-based ranging. It involves a first wireless device that divides a frequency bandwidth available for ranging procedures into multiple subbands using orthogonal frequency-division multiple access (OFDMA) techniques. The first wireless device transmits a trigger frame that assigns a subband to each neighboring wireless device, allowing for simultaneous transmission of sounding signals. This innovation supports sounding procedures for larger quantities of neighbor wireless devices by utilizing combined multiple input multiple output (MIMO) and OFDMA techniques.
Another notable patent is "Uplink flow control." This patent describes methods, systems, and devices for wireless communications that improve the management of uplink communications. In this system, an access point (AP) monitors a buffer to determine if the quantity of buffered uplink traffic from a station exceeds a set buffer quota. The AP can then modify the uplink communication scheme to reduce the quantity of uplink traffic, ensuring efficient communication with the station.
