Abstract: The disclosed technology is directed towards dynamic spread spectrum (DSS) deployments, in which two cells such as an LTE cell and a new radio (NR) cell share available physical resource blocks during a given transmission time interval. The LTE cell and NR cell determine priority values for their user equipments to be scheduled, and both cells provide requested scheduling information including the priority values and requested resource blocks for user equipments in the upcoming transmission time interval. Based on the priority values, a real-time joint scheduler processes the combined scheduling information from both cells to determine how many physical resource blocks of the total available to allocate to the LTE cell and how many to allocate to the NR cell for the next transmission time interval. To avoid collisions, the LTE cell and NR cell modify their respective UE schedules based on their respective number of allocated physical resource blocks.

Abstract: In one example, a method and apparatus for web browsing on multihomed mobile devices having multiple communication interfaces are disclosed. In one example, the method establishes a primary multiple path transmission control protocol subflow for the transfer of a resource from a server to a user endpoint device. The method then determines a threshold of resource size. When the size of the resource is determined to exceed the threshold, the method establishes a secondary multipath transmission control protocol connection that cooperates with the primary multiple path transmission control protocol subflow for the transfer of the resource from the server to the user endpoint device.

Abstract: The described technology is generally directed towards wireless communications for vehicle collision response. Devices onboard vehicles can wirelessly exchange information in response to detecting a collision. Public encryption keys can be exchanged, and exchanged information can optionally be encrypted using a received public encryption key. Exchanged information can include vehicle identification information and collision information. The collision information can furthermore be certified using a vehicle's private encryption key.

Abstract: The described technology is generally directed towards a transport protocol for latency sensitive applications. The disclosed transport protocol is “semi-reliable” in that it allows for specification of an importance of data being transmitted, thereby allowing important data to be sent reliably, while other data can be dropped if necessary, e.g., under bad network conditions. A deadline can be specified for such other data, and if the other data cannot be sent prior to the deadline, it can be dropped. Furthermore, the disclosed transport protocol can allow for early discovery of network jitter. A client device can send regular acknowledgments which identify most recently received data packets as well as a number of “heartbeat transmissions” received at the client device. A server device can use the acknowledgments to discover and respond to jitter.

Abstract: A system can obtain a labelled data set, including historic video data and labelled events. The system can divide the labelled data set into historic training/testing data sets. The system can determine, using the historic training data set, a plurality of different parameter configurations to be used by a video encoder to encode a video that includes a plurality of video frames. Each parameter configuration can include a group of pictures (“GOP”) size and a scenecut threshold. The system can calculate an accuracy of event detection (“ACC”) and a filtering rate (“FR”) for each parameter configuration. The system can calculate, for each parameter configuration of the plurality of different parameter configurations, a harmonic mean between the ACC and the FR. The system can then select a best parameter configuration of the plurality of different parameter configurations based upon the parameter configuration that has the highest harmonic mean.
