    Abstract: In systems and methods of determining the availability of a radio access technology, a first message is received from a wireless device in communication with an access node using a first radio access technology, wherein the first message comprises a request of the availability of a second radio access technology at the access node. Based on the first message, an identifier of the wireless device and an identifier of the first access node are determined. Based on the access node identifier, it is identified whether the second radio access technology is available at the access node, and a second message is sent to the wireless device instructing the wireless device to scan for the second radio access technology when it is available.

    Abstract: A throughput of information received from an access node at an application running on a wireless device is determined, and a modulation and coding scheme assigned to the wireless device to communicate with the access node is identified. Based on the throughput and the modulation and coding scheme, a number of free physical resource blocks per frame of the access node is estimated, to enable a determination of access node capacity.

    Abstract: At least one retransmission request is received from each of a plurality of wireless devices receiving a multicast broadcast, and a number of retransmission requests received from each of the plurality of wireless devices is determined. A first group of wireless devices is selected from among the plurality of wireless devices, and a delay time is determined for each wireless device in the first group based on the respective number of retransmission requests from each wireless device. When a data packet is not received at the one or more wireless devices of the first group, a timer is started at each of the wireless devices of the first group using the respective delay times. When the shortest delay time expires, another retransmission request is received from the wireless device comprising the shortest delay time of the one or more wireless devices.

    Abstract: In an embodiment, a location, a type of application, and a probability of transition to a no-coverage area are determined for each of a plurality of wireless devices in communication with an access node, and a collaborative group of wireless devices which have requested a data stream are selected. A first portion of the data stream is sent to each wireless device to synchronize the requested data stream, and at least one additional portion of the data stream is sent to each wireless device, where a number of the at least one additional portions sent to each wireless device is based on a modulation and coding scheme assigned to each wireless device. A mapping table is broadcast to the collaborative group, and the wireless devices exchange the additional portions of the data stream according to the mapping table when the collaborative group transitions to the no-coverage area.
