    Abstract: Upon satisfying a first handover condition based on signal measurements, an identity of the one or more target access nodes is determined, the identity being associated with a latency, and a determination is made whether or not to execute the handover based on at least the identifier or the latency of the one or more target access nodes. As macrocell access nodes are known to have smaller latency than small access nodes, the macrocell access node is a preferred target, regardless of signal measurements of the small access node. In embodiments, the type or latency of the target access node is weighted higher than the signal measurement for the determination of a preferred target access node. Target access nodes may be assigned priorities based on their type, latency, and signal measurements, and highest-prioritized target access nodes may be preferred as handover targets.

    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: Systems and methods are described for performing carrier aggregation based on subframe configuration. It may be determined that conditions for a wireless device in communication with an access node meet a carrier aggregation criteria, wherein the access node and wireless device communicate using a first subframe configuration. Signal information may be received from the wireless device comprising received signal levels for a plurality of candidate secondary carriers. Subframe configurations used by the candidate secondary carriers to communicate with wireless devices may be retrieved. One or more of the plurality of candidate secondary carriers may be selected based on the received signal level information and the retrieved subframe configurations. And carrier aggregation may be activated such that the one or more selected secondary carriers are used to transmit downlink data to the wireless device.

    Abstract: A method and system for controlling an access node includes prioritizing a plurality of wireless devices. The method also includes monitoring a position of a relay-capable wireless device and positions of the prioritized wireless devices. The method also includes determining the position of the relay-capable wireless device meets a first distance criteria and the position of prioritized wireless devices meets a second distance criteria. The method also includes assigning the relay-capable wireless device to a carrier aggregation configuration or an antenna diversity configuration based on the position of the relay-capable device and the position of the prioritized wireless devices. The method also includes assigning the prioritized wireless devices to the diversity configuration or the carrier aggregation configuration based on the position of the prioritized wireless devices.

    Abstract: Systems, methods, and processing nodes are related to allocating bandwidth in a wireless network. A method includes identifying a plurality of small cell relay nodes connected to a relay node. The method further includes determining priority data indicative of resource utilization by each of the plurality of small cell relay nodes and types of services utilized by wireless devices connected to each of the plurality of small cell relay nodes. Additionally, the method includes determining a priority for each of the plurality of small cell relay nodes based at least partially the priority data. The method also includes allocating backhaul bandwidth of the relay node to each of the plurality of small cell relay nodes based at least partially on the priority for each of the plurality of small cell relay nodes.

    Abstract: Exemplary embodiments described herein include systems, methods, and nodes for distributing relay wireless devices across an access node. Network identification numbers associated with at least two wireless devices may be determined. At an access node, a traffic class identifier and frequency band may be assigned to the at least two wireless devices, wherein each frequency band available for communication at the access node is assigned at most a maximum number of wireless devices comprising a network identification number that meets the criteria. Data may then be communicated between the access node and the at least two wireless devices according to the assigned traffic class identifiers and frequency bands, wherein the wireless devices comprise relay wireless devices that relay data between the access node and one or more small cells.
