Patent number: 11516756Abstract: Systems and methods are provided for optimizing the scheduling of Orthogonal Frequency-Division Multiple Access (OFDMA) transmissions in the downlink (DL) direction. A two-stage mechanism can be implemented when effectuating DL OFDMA transmission involving multiple modulation and coding schemes (MCS) in a single transmit burst. A first stage of the two-stage mechanism may use radio frequency (RF) boosting/de-boosting of Resource Units (RUs) such that the average input power to an AP power amplifier (PA) may remain under a saturated PA output power to ensure PA linearity. If RF boosting/de-boosting is not supported, an alternative mechanism for OFDMA grouping (to rigid grouping) can be employed to skip higher MCS.Type: GrantFiled: March 29, 2021Date of Patent: November 29, 2022Assignee: Hewlett Packard Enterprise Development LPInventors: Farhan Hasnain, Mohd Shahnawaz Siraj, Eldad Perahia, Deven Patel, Sachin Ganu

Publication number: 20220330136Abstract: Systems and methods are provided for multiple basic service set identifier (MBSSID) beaconing (from an access point (AP) standpoint) and MBSSID/virtual AP (VAP) scanning (from a client device perspective). To facilitate easier discovery of mesh APs/VAPs, BSSIDs associated with mesh VAPs can be advertised more frequently, e.g., being broadcast as a transmitted or non-transmitted BSSID in each MBSSID beacon. Additionally, information regarding mesh VAPs, such as mesh capability information, can be provided via intermediate discovery beacons or frames such that out-of-band scanning mechanisms can discover mesh VAPs faster. Additionally still, the existence of mesh VAPs can be advertised in a dedicated field of an MBSSID beacon.Type: ApplicationFiled: April 9, 2021Publication date: October 13, 2022Inventors: MOHD SHAHNAWAZ SIRAJ, QIANG ZHOU, ANDRE BEAUDIN

Patent number: 11375451Abstract: The full efficiency gains of the Target Wake Time (TWT) mechanism specified in the 802.11ax standard may not be realized when stations associated to an access point (AP) are spread across multiple Base Station Service Identifiers (BSSIDs). In such a scenario, TWT as conventionally utilized/specified in the 802.11ax standard, cannot properly coordinate sleep/wake schedules for stations due to associating to different BSSIDs. Accordingly, various embodiments are directed to grouping stations associated to multiple BSSIDs of an AP to allow for the synchronization (or staggering) of TWT, and facilitate multi-user transmissions, both in the uplink and downlink directions.Type: GrantFiled: October 2, 2020Date of Patent: June 28, 2022Assignee: Hewlett Packard Enterprise Development LPInventors: Abhiruchi Dakshinkar, Gaurav Patwardhan, Mohd Shahnawaz Siraj, Sachin Ganu, Eldad Perahia, Nitin Changlani
