Abstract: In systems and methods of selecting access nodes for broadcast, signal strength metrics are received from a plurality of wireless devices, wherein the signal strength metrics are based on signals received by the plurality of wireless devices from a plurality of access nodes. A first signal strength criteria is determined for each of the wireless devices based on the received signal strength metrics, and wireless devices for which the first signal strength criteria meets a threshold are selected from among the plurality of wireless devices. A second signal strength criteria is determined for each of the plurality of access nodes. A minimum number of the access nodes is selected wherein the second signal strength criteria meets the threshold for each of the selected wireless devices, and a multicast transmission is transmitted from the selected access nodes to the selected wireless devices.

Abstract: A database is maintained that maps source cell regions to channel condition on the neighbor cell(s) coverage. The database also tracks whether the neighbor cell has better, weaker, or similar signal strength than the source cell. The channel condition and bitrate requirement of each wireless device being served by the source cell are also tracked. Once a particular neighbor cell has been selected for traffic offload (i.e., handover of one or more wireless devices), the source cell uses the database to select which wireless devices should send measurement reports. Those wireless devices with channel conditions that are mapped in the database to the target cell's coverage are designated for possible selection. Among these wireless devices, either the wireless devices with the highest or lowest bitrate requirements are selected to provide measurement reports for the target cell.

Abstract: A system and method of scheduling communication in a wireless communication network are provided. A scheduling scheme comprising a first subframe and a second subframe can be determined to communicate data between a first access node and first wireless devices, and a second access node and second wireless devices. A resource request can be received from one of the first wireless devices. An interference indication can be determined based on the resource request. The first access node can be instructed to communicate with the first wireless devices during the first subframe and the one of the first wireless devices can be instructed to transmit data to the first access node during the second subframe when the interference indication meets an interference criteria. The second access node can be instructed to transmit data addressed to at least one of the second wireless devices during the second subframe.

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: In systems and methods for reducing network traffic generated by a plurality of wireless devices operating over a communication network, an indication is received at an access node when a plurality of wireless devices assigned to a subscriber operate simultaneously as active wireless devices over a communication network. A priority list of the active wireless devices arranged according to the highest priority based on operating parameters of the active wireless devices is compiled. One of the active wireless devices is selected as a wireless host device based on the active wireless devices based upon the compiled priority list. Channel state data received from the active wireless devices at the access node is correlated to determine whether the active wireless devices and the wireless host device are in close proximity with each other. A wireless connection is established between the wireless host device and the active wireless devices, that are found to be in close proximity of wireless host device.

Abstract: Mitigating interference in such potential interference areas of a wireless communication network includes determining that a first sector associated with a first wireless air interface and configured with a first subcarrier spacing is facing a second sector associated with a second wireless air interface and configured with a second subcarrier spacing, wherein the first and second subcarrier spacings are different, and assigning resources towards the second sector in a different order than resources assigned to the first sector.
