The time between a determination by a station to enter a power saving mode and entering network sleep mode by the station may be reduced through a transmission, by an AP, of an MPDU to the station successive to an SIFS after transmission of an acknowledgement to the station of a PS-Poll frame from the station. The time to enter a power saving mode by a station may also be reduced through transmission of A-MPDUs in which a last MPDU of the A-MPDU has an indicator bit cleared to indicate no additional data is to be transmitted. An AP may prevent a retransmission of an MPDU to the station in the absence of an acknowledgement from the station, to further enhance efficiency. | 11-20-2014 |
20140341099 | ACCESS POINT RESPONSE TO PS-POLL - Methods, systems, and devices are described for power conservation in a wireless communications system through efficient transmissions and acknowledgements of information between an AP and a station. The time between a determination by a station to enter a power saving mode and entering network sleep mode by the station may be reduced through a transmission, by an AP, of an MPDU to the station successive to an SIFS after transmission of an acknowledgement to the station of a PS-Poll frame from the station. The time to enter a power saving mode by a station may also be reduced through transmission of A-MPDUs in which a last MPDU of the A-MPDU has an indicator bit cleared to indicate no additional data is to be transmitted. An AP may prevent a retransmission of an MPDU to the station in the absence of an acknowledgement from the station, to further enhance efficiency. | 11-20-2014 |
20140344490 | MEDIA TIME BASED USB FRAME COUNTER SYNCHRONIZATION FOR WI-FI SERIAL BUS - A method of transmitting universal serial bus (USB) frames over a communications channel is disclosed. A USB device receives one or more USB frames from a host device via a network, wherein the one or more USB frames are encapsulated in one or more data packets based on a communications protocol associated with the network. The USB device further synchronizes a local clock signal with a clock signal of the host device using a clock synchronization mechanism of the communications protocol. The USB device then determines a number of USB frames transmitted by the host device and processes the one or more USB frames based, at least in part, on the synchronized local clock signal. For some embodiments, the USB device may receive a frame count value and a corresponding media time value from the host device. | 11-20-2014 |
20150063208 | SYSTEMS AND METHODS FOR SERVICE IDENTIFICATION IN NEIGHBORHOOD AWARE NETWORKS - Systems and methods in accordance with various embodiments provide for robust service IDs for utilization in wireless devices in neighbor aware networks. In certain embodiments, a service ID is generated as a hash value from a diversified input string. One aspect of the subject matter described in the disclosure provides a method of transmitting service information in a wireless neighborhood aware network. The method includes generating, via a wireless device, a message including a hash value of a data string, the data string including both a name of a service and information identifying a type of the message. The message further includes a matching filter field including matching filter information that characterizes the service named in the data string. The method further includes transmitting the message. | 03-05-2015 |
20150071084 | SYSTEM AND METHOD FOR INFORMATION VERIFICATION BASED ON CHANNEL AWARENESS - This disclosure describes techniques for operating a client device to communicate with a wireless access point to validate data within a frame by comparing channel quality metrics and duration metrics to thresholds. Information received within a validity window may be treated as correctly received even if the frame fails a subsequent verification process or if reception of the frame is terminated prior to the end of the frame. | 03-12-2015 |
20150072641 | System and Method for Providing User Notifications - A method performed by an end user device associated with a service plan having a limit on usage of a network service, the method comprising storing one or more notification actions corresponding to one or more notification requests; performing a device action that reflects a past or intended use of the network service; receiving one of the one or more notification requests from a network element in response to the device action; performing one of the one or more notification actions in response to the notification request, the notification action causing the end user device to retrieve at least a portion of a notification message associated with a status of the use, the at least a portion of the notification message being separate from the one of the one or more notification requests; and presenting the notification message on a user interface of the end user device. | 03-12-2015 |
