Abstract: A method of operating a communication system includes communicating data between an access node and a wireless device using carrier aggregation. This carrier aggregation includes communicating using at least a primary carrier and a secondary carrier. The communication system determines that conditions for the secondary carrier meet a beamforming requirement criteria. The communication system determines an angle of arrival of the primary carrier. Based on the angle of arrival determined for the primary carrier, beamforming is applied to the secondary carrier.

Abstract: Systems and methods are described for determining a carrier for a wireless device. Data may be communicated between a wireless device and a wireless communication network over a first carrier. It may be determined whether the wireless communication network provides a fallback protocol for switching the wireless device from the first carrier to a second carrier. The wireless device may be instructed to communicate with the wireless communication network over the second carrier when it is determined that the wireless communication network does not provide the fallback protocol.

Abstract: Systems and methods are described for allocating resources using enhanced semi-persistent scheduling (SPS) in a wireless network. A plurality of wireless devices may be in wireless communication with an access node. Based on application requirements of the wireless devices, the access node may allocate dedicated resource slots on a persistent schedule for each wireless device requesting SPS services. The wireless devices having the SPS allocations of dedicated resource slots are monitored at intervals for changes in amount of resource usage above or below the size of the dedicated resource slot for each wireless device. If a data transmission for a wireless device exceeds the dedicated resource slot allocated to that wireless device, then the transmission may be truncated, with a first portion being transmitted in the dedicated resource slot and a second portion being transmitted in one or more non-dedicated resource slots.

Abstract: It is identified that an attempted handover of a wireless device from a first access node to a second access node meets a failure criteria, where the attempted handover uses a handover initiation timer and a signal level modifier. A first signal level of the first access node, and a second signal level of the second access node, received at the wireless device at a time when the attempted handover was initiated are determined. At least one of the handover initiation timer and the signal level modifier is adjusted based on the failure criteria, the determined first signal level, and the determined second signal level.

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: Systems and methods are described for scheduling transmissions from an access node. A location may be determined for a plurality of small cells within an access node signal area. Based on the determined locations, a scheduling algorithm may be selected for the access node, where the scheduling algorithm may comprise one of a low proportional fairness scheduling algorithm, a medium proportional fairness scheduling algorithm, and a high proportional fairness scheduling algorithm. Data may then be transmitted from the access node to a plurality of wireless devices based on the selected scheduling algorithm.

Abstract: A system and method of allocating communication resources to a wireless device in a wireless communication network are provided. A first subframe configuration can be assigned to a first carrier of a frequency band of an access node. A second subframe configuration different from the first subframe configuration can be assigned to a second carrier of the frequency band. The access node can receive a resource request associated with an application running on the wireless device. An application requirement of the application running on the wireless device can be determined. The wireless device can be instructed to establish communication with the access node over one of the first carrier and the second carrier during a communication session based on the determined application requirement.

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.
