Abstract: Systems and methods are described for scheduling wireless transmissions from an access node based on service provider. Data may be communicated between an access node and a plurality of wireless devices, wherein each of the plurality of wireless devices uses one of a first service provider and a second service provider to communicate with an access node. Transmissions may then be scheduled from the access node to the plurality of wireless devices based on a provider priority for the service providers and a backhaul congestion for each of the service providers.

Abstract: Systems, methods, and processing nodes are related to improving service in a wireless network. The method includes determining a frame configuration and bandwidth for a plurality of communication bands available for communication with a wireless device. The method includes generating a reselection priority based on one or more of the frame configuration and bandwidth for each of the plurality of communication bands. The reselection priority of each of the plurality of communication bands is based on a suitability of one or more of the frame configuration and bandwidth to service uplink traffic. The method includes transmitting the reselection priority to the wireless device. The wireless device utilizes the reselection priority in communication band reselection based on uplink traffic generated by the wireless device.

Abstract: Systems and methods are described for cross scheduling transmissions from an access node. Data may be communicated between an access node and a wireless device over a first frequency band. A first application and a second application associated with the wireless device may be determined, where each of the applications comprises an application type. Based on the application type one of the first frequency band and a second frequency band may be selected for the first application and the second application, where the selected frequency bands are different. Transmissions associated with the first application may then be scheduled over the frequency band selected for the first application and transmissions associated with the second application may then be scheduled over the frequency band selected for the second application.

Abstract: Systems and methods are described for determining a subframe configuration for an access node based on coverage. An access node may communicate with wireless devices using a subframe configuration, however there may be a plurality of subframe configuration options. A utility function may be calculated for each of the plurality of subframe configurations based on, for example, a coverage for each subframe configuration and a number of wireless devices serviced by each subframe configuration. The utility function may provide an indication of a subframe configuration's value to the wireless system based on considerations such as coverage over wireless devices and signal quality for the covered wireless devices. The subframe configuration with the greatest utility function may then be selected to be used for communication between the access node and wireless devices.

Abstract: Video is multicast to a group of wireless devices as a series of video segment files containing the video frame data for a period of the video stream. After receiving a video segment file, the wireless devices report about the quality of their reception of the video segment. If a threshold percentage (or number) of wireless devices report they experienced poor reception of a video segment, the number of subframes (i.e., transmission time intervals) used in a frame to multicast the video is increased. In other words, if the number of wireless devices that report they experienced poor reception of a video segment is higher than some threshold, the number of subframes allocated to redundantly transmit the streaming video data is increased.

Abstract: Systems and methods are described for adjusting subframe transmissions based on uplink data rate. Data may be communicated between an access node and a plurality of wireless devices, wherein the data is scheduled for communication according to a first subframe configuration with a first mix of uplink and downlink subframes. An uplink data rate for at least one of the plurality of wireless devices over a first portion of a period of time may be compared to an uplink criteria. A scheduling for a set of subframes over a second portion of the period of time may be adjusted based on the comparison such that the set of subframes comprises a second mix of subframes, wherein the second mix comprises a greater proportion of uplink subframes than the first mix. And data may be communicated between the access node and the plurality of wireless devices according to the adjusted scheduling for the set of subframes, wherein the uplink data rate for the at least one wireless device is increased over the second portion of the period of time.
