Patent number: 11871367Abstract: Disclosed herein are related to systems and methods for a multiple-input multiple-output (MIMO) communication. In one aspect, during a first time period, a master access point transmits, to a slave access point, information for a joint transmission by the master access point and the slave access point. In one aspect, the slave access point estimates synchronization information for the joint transmission, according to the information for the joint transmission. In one aspect, during a second time period after the first time period, the master access point transmits a portion of a null data packet to a station device. In one aspect, during the second time period, the slave access point transmits the portion of the null data packet to the station device, based on the synchronization information for the joint transmission. In one aspect, the station device determines steering information for the MIMO communication, according to the null data packet.Type: GrantFiled: May 20, 2022Date of Patent: January 9, 2024Assignee: Avago Technologies International Sales Pte. LimitedInventors: Ron Porat, Srinath Puducheri Sundaravaradhan, Karim Nassiri Toussi, Jun Zheng

Publication number: 20230239743Abstract: Systems, devices, methods, and computer-readable storage media of channel switching. One device for channel switching includes a memory and at least one processor. The at least one processor is configured to communicatively couple with one or more client devices, using one of a primary bandwidth channel or a secondary bandwidth channel and transmit a first trigger on at least the primary bandwidth channel to at least a first client device of the one or more client devices based on at least one of (i) a bandwidth availability (ii) a quality of service parameter, or (iii) a secondary bandwidth switching capability, wherein the first client device switches from the primary bandwidth channel to the secondary bandwidth channel in response to the first trigger.Type: ApplicationFiled: January 19, 2023Publication date: July 27, 2023Applicant: Avago Technologies Intemational Sales Pte.
