Abstract: A method is provided for dynamically modifying a buffer in a network deploying multiple carriers, wherein multiple wireless devices communicate over the network. The wireless devices run applications, each application belonging to an application category. The method includes identifying the application category for a selected wireless device communicating over the network, wherein a first application category requires at least one of high throughput and low latency. The method additionally includes reducing a size of the buffer when the application category is the first application category, thereby initiating carrier aggregation for the selected wireless device.

Abstract: Limiting dual connectivity in a wireless sector served by at least two wireless air interfaces includes monitoring a pairing efficiency metric of wireless devices in the wireless sector. When the pairing efficiency metric rises above a threshold, a maximum number of wireless devices able to attach to one of the at least two wireless air interfaces is increased, and when the pairing efficiency metric falls below the threshold, the maximum number of wireless devices able to attach to one of the at least two wireless air interfaces is decreased. The wireless air interface for which dual connectivity is limited can be a 5G interface, and load is alleviated by limiting dual connectivity thereto.

Abstract: Beamforming in massive MIMO networks includes monitoring beamforming feedback from one or more wireless devices attached to an access node, when the beamforming feedback degrades, increasing a subcarrier spacing of the access node, and when the beamforming feedback stops degrading, maintaining or reducing the subcarrier spacing of the access node.

Abstract: Mitigating interference caused by external networks includes identifying air interface resources within a wireless air interface that are subject to interference from the external network, scheduling resources for a first one or more wireless devices reporting channel conditions that meet a threshold or being a threshold distance from a serving access node to avoid using the identified air interface resources, and instructing a second one or more wireless devices reporting channel conditions that do not meet the threshold or within a threshold distance from the serving access node to use the identified air interface resources.

Abstract: Systems, methods, and processing nodes are configured to perform scheduling in a wireless network utilizing a multi-user multiple-input multiple-output (MU-MIMO) operating mode, by determining that a throughput indicator of a sector meets a threshold, and adjusting a time window during which a first one or more wireless devices are removed from a MU-MIMO group and a second one or more wireless devices are added to the MU-MIMO group. The first one or more wireless devices comprise any wireless device that has a throughput below a threshold, and the second one or more wireless devices comprise any wireless device that has not been in the MU-MIMO group for a predefined time period.

Abstract: Systems, methods, and processing nodes for performing carrier aggregation in a wireless network including obtaining, at a relay access node, a control channel load level of a first carrier deployed by a donor access node, determining, at the relay access node, that the control channel load level is within an acceptable load level, and aggregating the first carrier with a second carrier deployed by the relay access node to communicate with a wireless device attached to the relay access node.

Abstract: Systems and methods are described for assigning a mobility parameter to a wireless device. One or more measurement reports may be collected at an access node from the wireless device. A pathloss change for the wireless device may be calculated based on the collected measurement reports. When the calculated pathloss change exceeds a threshold, the wireless device may be instructed to report surplus transmit power at the access node. The reported surplus transmit power may be correlated to preset location environments and a position of the wireless device classified based on the correlation. A mobility parameter may be assigned for the wireless device.

Abstract: Mitigating interference between access nodes in a wireless network includes determining interference caused to uplink signals received at a first access node by downlink signals transmitted from a second access node, and adjusting a guard period of a special subframe utilized by one or both of access nodes based on determining the interference, by switching special subframe formats to include a longer guard period. Overall interference is mitigated based on mutually-experienced propagation delay, and channel reciprocity. Adjustments are associated with known distances between access nodes.

Abstract: Devices, systems, and methods for scheduling resources in a wireless network are configured to perform operations including identifying one or more resources that are available for low-priority transmissions from an internet-of-things (IoT) device, determining that the available resources are non-contiguous, rescheduling scheduled resources until the available resources are contiguous, and scheduling the low-priority transmissions using the available resources.

Abstract: Beamforming in massive MIMO networks includes monitoring a signal condition such as pathloss of wireless devices and, based thereon, selecting a type of reference signal for the wireless devices, the type selected from among a non-precoded reference signal, a beamformed reference signal, or a standard reference signal. Further, an MCS of the wireless devices is monitored and, based thereon, the type of reference signal is adjusted.
