Abstract: Systems, methods, and processing nodes for obtaining radio network characteristics associated with network traffic, determining a type of network traffic and/or network session, allocating resources towards a network traffic session based on the type thereof (or type of network traffic), and performing additional network optimization operations based thereon, including but not limited to metering, billing, and service adjustments such as reallocation of resources. Consequently, resource usage patterns of different data types can be made predictable to a network operator, enabling optimal allocation of network resources, adjustments of latency, and thus providing an optimal user experience.

Abstract: Selecting a donor access node for a relay node includes identifying operating frequencies for carriers deployed by the relay node, and determining backhaul frequencies that minimize interference with the operating frequencies, including identifying frequency bands that are separated from the one or more operating frequencies by at least a threshold amount. Primary and secondary carriers can be identified and communicated with potential donor access nodes.

Abstract: Systems, methods, and processing nodes for performing carrier aggregation in a wireless network include associating a primary usage type of an application running on a wireless device with a characteristic of a first carrier based on at least a first frequency band utilized by the first carrier, associating a secondary usage type of the application with a characteristic of a second carrier based on at least a second frequency band utilized by the second carrier, assigning the first carrier as a primary carrier for the wireless device when operating in a carrier aggregation mode, and assigning the second carrier as a secondary carrier for the wireless device when operating in the carrier aggregation mode.

Abstract: Device-to-device (D2D) transmissions by a wireless device may interfere with base station reception of other signals. To mitigate this interference, the wireless device estimates the path loss between itself and the base station. The path loss and the current D2D transmission power level are used to estimate the amount of interference the base station is experiencing as a result of the D2D transmissions from the wireless device. Based on the estimated interference experienced by the base station, the wireless device increases the robustness of the MCS being used and decreases the transmission power level by a corresponding amount. By decreasing the D2D transmission power level, less interference will be experienced by the base station. By increasing the robustness of the MCS, the impact of the reduced D2D transmission power level is mitigated.

Abstract: Using a scheduler, communication may be scheduled between an access node and a plurality of wireless devices, wherein the plurality of wireless devices comprise one or more relay wireless devices or device to device (D2D) wireless devices. Using the scheduler, at least one relay wireless device or D2D wireless device may be scheduled using a semi-persistent scheduler comprising an adjusted periodicity, wherein a default periodicity used by the semi-persistent scheduler for end-user wireless devices is different from the adjusted periodicity. Data may be communicated between the access node and the at least one relay wireless device or D2D wireless device using the adjusted periodicity.

Abstract: Systems, methods, and processing nodes for communicating with a wireless device via at least two access nodes include communicating with a wireless device via at least two access nodes includes receiving, at a relay access node coupled to a donor access node, downlink data intended to be transmitted to an end-user wireless device attached to the relay access node; determining that a signal condition at the relay access node meets a criteria; and in response to determining that the signal condition meets the criteria, forwarding the downlink data to the donor access node. The donor access node transmits the downlink data to the end-user wireless device, and the relay access node maintains a control channel with the end-user wireless device.

Abstract: Systems and methods are described for managing conflicts between a load balancing protocol and a neighbor relations protocol. Network characteristics for an access node in communication with a plurality of wireless devices may be determined. The plurality of wireless devices may be classified into a high priority class and a low priority class based on a traffic requirement for each of the wireless devices. The determined network conditions my then be compared to a criteria. Based on the comparison, the high priority class of wireless devices may be instructed to perform one of a neighbor relations protocol and a load balancing protocol.

Abstract: An interference level is determined in an uplink portion of a wireless communication link between a wireless device and an access node. A traffic class of data is identified in a first portion of the uplink portion, and resource blocks in a second portion of the uplink portion are selected based on the determined interference level and the identified traffic class. The wireless device is sent an allocation of the selected resource blocks in the second portion of the uplink portion, and control channel information is received from the wireless device in the uplink portion in the selected resource blocks.
