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: 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: 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: Systems, methods, and processing nodes for minimizing interference caused by high-powered wireless devices to other wireless devices in the network by determining that a first wireless device assigned to a first power class is located in a potential interference zone of a coverage area of an access node, and deactivating a high-powered transmission mode of the first wireless device. The high-powered transmission mode utilizes a first transmission power level that is associated with the first power class. The potential interference zone is defined based on standard-powered uplink transmissions that have a high noise or low SINR.

Abstract: Systems and methods are described for selecting relay nodes for Single-User Multiple-Input-Multiple Output (SU-MIMO). A channel orthogonality and Signal-to-Interference-Plus-Noise Ratio (SINR) of a plurality of wireless devices located in a geographic area of an access node is determined. A relay-capable status of the plurality of wireless devices is determined. Non-relay capable wireless devices located in the geographic area are excluded from SU-MIMO. From the plurality of wireless devices, relay-capable wireless devices are selected for SU-MIMO. The selected relay-capable wireless devices are prioritized for SU-MIMO based on a channel orthogonality and SINR meeting a set threshold.
