Abstract: Features are provided for the asynchronous transmission of media files that are part of, or otherwise associated with, user-created content posts. The media file transmissions are asynchronous in nature because the media files are transmitted in parallel background processes while users continue creating content posts or performing other computing tasks. The client devices on which the media file transmissions are initiated can manage the establishment of connections to a network-accessible content management system, and also manage the continued transmission of the media files to the content management system while the users perform other tasks using the client devices.

Abstract: An apparatus is provided. The apparatus comprises a controller configured to operate in an access point (AP) mode. The apparatus also includes a processing device. The processing device is configured to transmit a signal to one or more stations (STAs) to prevent the one or more STAs from using a frequency band. The frequency band is shared by the one or more STAs and a radio. The processing device is also configured to detect that the frequency band is available for use by at least one STA of the one or more STAs to transmit uplink signals to the controller without interfering with the radio; and in response, transmit a trigger frame to the at least one STA to schedule the at least one STA to transmit the uplink signals to the controller using the frequency band.
Abstract: Disclosed are methods and systems for delaying packet transmissions over a wireless communication channel until a more favorable channel condition is detected. A device may measure a channel metric when it receives periodic beacon signals. The device may compare the channel metric against a programmed metric threshold. If the channel metric is less than the metric threshold, the device may delay the transmission of a packet until a later transmission window or transmit opportunity (TXOP) when the channel metric rises above the metric threshold, indicating the presence of a more favorable condition for transmission, or until a preconfigured timeout period elapses before the more favorable condition is found.
Abstract: Embodiments can include a method in which a transmission duration for data frames to a plurality of different receiving devices is determined by a transmitting device.

Abstract: Features are provided for proactively grouping content for personalized content feeds based on the expected relevance of the content to groups or classes of users. Such proactive grouping can allow personalized (or semi-personalized) content feeds to be delivered with low user-perceived latency. The proactive grouping may be used in conjunction with a more computationally-intensive and higher-latency process for generating personalized feeds. A user's content feed may be provided using a two-phase delivery process in which an initial set of content for the feed is provided from the proactively grouped content collection with which the user is associated. While the user is viewing the initial set of content, the second phase of the delivery process may be performed in which additional content is selected specifically for the user.
