Abstract: A system may include an access node to deploy a radio air interface to provide wireless services to one or more wireless devices. The access node may include processing circuitry. The processing circuitry of the access node may monitor an amount of packet drops at a shared network device of a dual connectivity access-node-pair. The processing circuitry of the access node may dynamically adjust one or more handover parameters based on the amount of packet drops at the shared network device. The handover parameters may be adjusted to inhibit handovers to the dual connectivity access-node-pair.

Abstract: Systems for mitigating interference in a massive MIMO wireless network include an access node, a plurality of antennae communicatively coupled to the access node, and a processor communicatively coupled to the access node. The processor can be configured to perform operations including communicating with one or more wireless devices within a wireless sector utilizing one or more antennae from the plurality of antennae, and monitoring an interference level within the wireless sector. Upon the interference level meeting a threshold, the processor may be configured to utilize fewer antennae to communicate with the one or more wireless devices. Conversely, upon the interference level not meeting the threshold, the processor may be configured to utilize more antennae to communicate with the one or more wireless devices.

Abstract: A pairing efficiency and/or a resource usage associated with wireless devices attached to a sector are monitored. Responsive to determining that the pairing efficiency is below a threshold and/or the resource usage is higher than a threshold, one or more pairing criteria are adjusted to increase MIMO pairing, thereby exploiting the benefits of massive MIMO in wireless networks.

Abstract: Systems, methods, and processing nodes are configured to manage transmission characteristics in a wireless network, such as a wireless network that employs MIMO techniques, by identifying an undesired signal, the undesired signal originating from a communication device external to the wireless network and determining that a signal parameter value of the undesired signal exceeds a threshold value. An operating parameter of a multi-element antenna for communicating signals in the wireless network is adjusted when it is determined that the signal parameter value exceeds a threshold value.

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: Exemplary embodiments described herein include systems, methods, and nodes for managing channel quality for a relay wireless device. Interference experienced in one or more sectors of an access node that include a relay wireless device may be monitored. It may be determined that the monitored interference in at least one sector of the access node meets a mitigation criteria. One or more potential interfering sectors from access nodes neighboring the access node that are performing reference signal power boosting may be identified such that the potential interfering sectors are adjacent to the one sector of the access node. One or more neighboring access nodes may be instructed to selectively reduce reference signal power boosting in the potential interfering sectors.
