Patent number: 11902912Abstract: Optimal determination of transmit power level for MLDs in A Wireless Local Area Network (WLAN). An AP can establish synchronous downlink multi-link operations with another MLD. A first link and a second link between the AP and the MLD both operate in a same sub-band. The AP can then determine the same power level for both the first link and second link. After establishing the same power level, the AP can then determine a second power level for the first link and a third power level for the second link. The second power level is greater than the third power level. The AP can then provide the second power level for the first link and the third power level for the second link.Type: GrantFiled: December 30, 2022Date of Patent: February 13, 2024Assignee: Cisco Technology, Inc.Inventors: Sivadeep Reddy Kalavakuru, John Martin Blosco, Fred Jay Anderson, Ardalan Alizadeh, Gautam D.

Patent number: 11832197Abstract: Techniques for neighborhood management between WiFi and unlicensed spectrum radios. A wireless access point (AP), including a first radio, identifies a neighboring second radio operating using at least a portion of an unlicensed radio spectrum, based on a time that the AP receives a transmission from the second radio using a frequency within the unlicensed radio spectrum. Transmission between the first radio and the second radio is synchronized by identifying a clock offset between a first clock relating to the first radio and a second clock relating to the second radio.Type: GrantFiled: June 29, 2021Date of Patent: November 28, 2023Assignee: Cisco Technology, Inc.Inventors: Gautam D.

Patent number: 11777699Abstract: A wireless access point device is full-duplex capable and serves wireless communication for at least first and second wireless client devices. The wireless access point device sends to the first wireless client device a trigger frame that causes the first wireless client device to send an uplink transmission to the wireless access point after a first time interval. The wireless access point device waits a second time interval after the first wireless client is expected to begin sending the uplink transmission. The wireless access point device receives the uplink transmission from the first wireless client device. After the second time interval, and while receiving the uplink transmission from the first wireless client device, the wireless access point device sends to the second wireless client device a downlink transmission that overlaps at least partially in frequency and time with the uplink transmission from the first wireless client device.Type: GrantFiled: June 9, 2022Date of Patent: October 3, 2023Assignee: CISCO TECHNOLOGY, INC.Inventors: Pooya Monajemi, Brian Hart, Matthew Aaron Silverman, Gautam D.

Patent number: 11678205Abstract: Optimal determination of wireless antenna configurations may be provided. A computing device may direct an antenna array of an Access Point (AP) to generate a wide beamwidth, to locate a cluster of two or more stations. Upon locating the cluster, the AP can narrow the beamwidth, and, with the narrower beamwidth, receive a key performance indicator (KPI) from at least one of the two or more stations in the cluster. The computing device may then generate a statistical model, based on the KPI and an antenna vector of the antenna array. Based on the statistical model, the computing device can determine a second antenna vector to optimize the KPI for one or more of the client stations. The computing device can then modify the antenna state of the AP to generate the determined antenna vector.Type: GrantFiled: June 6, 2022Date of Patent: June 13, 2023Assignee: Cisco Technology, Inc.Inventors: Sivadeep Reddy Kalavakuru, Ardalan Alizadeh, John Martin Blosco, Matthew Aaron Silverman, Gautam D.
