    Abstract: Systems and methods are described for mitigating interference from neighbors. Interference may be monitored at a first access node, wherein the monitoring includes detecting an interference pattern over at least two monitored subframes. The interference pattern may be analyzed to identify one or more interference sources, wherein a first interference pattern indicates interference caused by a neighboring access node and a second interference pattern indicates interference caused by one or more wireless devices communicating with a neighboring access node. The identified interference sources may be instructed to adjust transmissions based on the monitored interference.

    Abstract: Methods and systems for balancing traffic in a wireless network by controlling DAS and an access node of a macro nodes to direct a wireless device to the system with the lowest latency, according to a priority of an application of a wireless device. The method includes receiving an indicator of an application type, or a bearer type, from a wireless device, determining a processing delay of a distributed antenna system, determining a priority of the received signal, and in response to the processing delay of the distributed antenna system meeting a first criteria and a quality of service indicator meeting a second criteria, directing the wireless device to an access node.

    Abstract: Performing carrier aggregation for high-powered wireless devices that may cause interference to other wireless devices includes determining that a wireless device attached to an access node is assigned to a high power class and capable of operating in a carrier aggregation mode, initiating the carrier aggregation mode for the wireless device, and instructing the access node to utilize a frequency-division-duplexing (FDD) carrier deployed by the access node as a primary carrier for the wireless device. A handover of the wireless device to the FDD carrier may be triggered by a threshold level of interference caused by uplink transmissions from the wireless device when operating in the high-powered transmission mode on a TDD carrier.

    Abstract: An access node can dynamically adjust a buffer allocation of a wireless device connected thereto, based on a packet loss or other signal degradation characteristic of a wireless link between the access node and the wireless device. The wireless device may be a relay node. The signal degradation may be indicated by a packet loss of data transmitted over the wireless link. Based on the detected signal degradation, the donor access node dynamically and in real-time adjusts a size of a buffer or sub-buffer allocated to the relay node. Threshold comparisons are used to determine when and by how much to adjust the buffer size. Operations are not limited to relay node buffers, and can be applied to buffers associated with standard wireless devices based upon signal characteristics thereof, an application requirement of the devices, or a historical trend of packets losses for the wireless links associated therewith.

    Abstract: Dual connectivity operations described herein include splitting a PDU into at least first and second portions of data addressed to or from first and/or second network addresses of a wireless device respectively, and modifying a source/destination address of the second portion of data from the first network address to the second network address in the downlink direction, and from the second network address to the first network address in the uplink direction. Uniquely-marked bearers set up between relay access nodes and donor access nodes (and gateways associated therewith) enable transmission of portions of data to and from the different network addresses.

    Abstract: Systems, methods, and processing nodes are related to preventing message overloading in a wireless network. The method includes establishing, by the access node, the wireless connection with the wireless device. The method also includes forwarding, from the access node to a controller node, a network connection message from the wireless device. The network connection message requests connection to network services of the wireless network. Additionally, the method includes receiving, at the access node from the controller node, a message indicating that the wireless device is denied access to the network services. Also, the method includes terminating, at the access node, the wireless connection with the wireless device in response to receiving the message. The method further includes limiting, at the access node, an establishment of future wireless connections with the wireless device in response to receiving the message.
