  • Patent number: 10628228
    Abstract: Systems for processing requests to use virtual computing resources in communicatively isolated computing environments apply a multi-tier framework for limiting the amount of virtual computing resources that can be allocated to a user in a computing environment. A bottom tier is associated with a user account that has not been analyzed for security risks, a top tier is associated with a user account that has been validated to use a corresponding computing environment; an intermediate tier, having limits between the bottom and top tiers, is applied to computing environments where the user has not requested resources. Initially, all computing environments are on the bottom tier. In response to a valid request for resources, validated computing environments are moved to the top tier and all other computing environments are moved to the intermediate tier. Requests in an intermediate-tier computing environment trigger validity review; the computing environment can move to top tier.

The HEW station may determine transmission activity during a first portion of a channel sensing period, and may select a sub-channel on which transmission activity is not determined. The HEW station may transmit an announcement signal on the selected sub-channel during a second portion of the channel sensing period. The announcement signal transmission may indicate, to other contending HEW stations, an intention by the HEW station to transmit on the same selected sub-channel during a subsequent access period.

  • Patent number: 9838902
    Abstract: Rather than using a large number of transceivers (transmitter/receiver pairs) operating in parallel, Access Points with multiple channels are used to aggregate, or stack, transmitted response communications, e.g., transmitting multiple acknowledgements (ACKs) in a single packet to one or more sources of received packets. The method includes sending on a plurality of channels, by each of a plurality of respective first nodes, a communication to a second node, receiving on the plurality of channels, by the second node, the communication from each of the plurality of first nodes and sending, by the second node, a transmission that contains a response to each communication that was successfully received from each of the plurality of first nodes. The response to each of the plurality of first nodes is part of a single message sent by the second node.

  • Patent number: 9730125
    Abstract: A technique for providing per station control of multiple stations in a wireless network across multiple access points. A look-up table that assigns a station connected to the access point and at least one communication parameter to each of a plurality of persistent, uniquely-assigned BSSIDs (Basic Service Set Identifiers) is stored. An access point responds to messages addressed one of the plurality of persistent, uniquely-assigned BSSIDs and ignores messages addressed to other BSSIDs. Persistence of the BSSID allows the controller to maintain individual control over each station after moving to a second access point of the plurality of access points. A frame comprising the plurality of BSSIDs corresponding to each connected station aggregated into the frame is generated. The frame is transmitted to the plurality of stations.

  • Patent number: 9680683
    Abstract: A radio receiver apparatus that can effectively utilize GI to improve the reception quality. In this apparatus, a data extracting part extracts a data portion of a direct wave from a signal subjected to a radio reception process by a received RF part. A GI extracting part extracts, from the signal subjected to the radio reception process by the received RF part, GI having a length determined by an extracted GI length deciding part. The extracted GI is adjusted by a data position adjusting part such that its rear end coincides with the read end of the extracted data portion. A combining part combines the extracted data portion with the GI the data position of which has been adjusted. The combined signal is then supplied to a frequency axis equalizing part, which equalizes the signal distortions of the combined signal on the frequency axis.
