Abstract: Systems and methods provide for assignment of wireless devices to a secondary node based on a characteristic of the wireless device and properties of the secondary node. The method may be triggered when noise reaches a predetermined threshold. HPUEs may be assigned to secondary nodes having a high reverse noise and channels having a high spectral efficiency and LPUEs may be assigned to secondary nodes having a lower reverse noise and a lower spectral efficiency.

Abstract: Subcarrier spacing is selected based on a change in an antenna configuration of an access node, wherein a spectral efficiency of the access node is reduced by the change in the antenna configuration. For example, the change in the antenna configuration is based on the access node deploying additional radio air interfaces using a limited quantity of antenna elements. The subcarrier spacing for at least one radio air interface is increased based on the reduction in spectral efficiency.

Abstract: Load balancing based on pairing efficiency includes monitoring a pairing efficiency metric of each carrier deployed by an access node, the access node being configured to utilize 5G EN-DC, and offloading wireless devices from a first carrier having a lower pairing efficiency to a second carrier having a higher pairing efficiency. Offloading includes adjusting reference signals associated with 4G and 5G carriers.

Abstract: Methods, systems, and processing nodes for ensuring uplink service for wireless devices capable of uplink split mode in EN-DC using both 4G LTE and 5G NR RATs, by selecting serving access nodes that are also capable of uplink split mode and/or coupled to large quantities of antenna elements relative to other potential serving access nodes. In particular, such serving access nodes are selected for wireless devices that exhibit one or more of a low power headroom, a high uplink buffer, or a high mobility.

Abstract: Systems, methods, and processing nodes are configured to manage wireless devices in a wireless network, such as a network that employs MIMO techniques, by receiving a request from a new wireless device for access to a wireless network using a first communication protocol, the wireless network using at least two communication protocols simultaneously, determining that a number of wireless devices in the wireless network using the first communication protocol of the at least two communication protocols meets a threshold number of wireless device, and adjusting an operating parameter of a multi-element antenna for communicating signals between an access node and the wireless devices in the wireless network using the first communication protocol when it is determined that the number of wireless devices in the wireless network using the first communication protocol meets the threshold number of wireless devices.

Abstract: Dedicating antenna elements to specific wireless devices by identifying specific wireless devices that meet a set of criteria, such as wireless devices using a certain application type that is associated with a bandwidth, and respectively dedicating a separate portion of antenna elements for communicating with each specific wireless device. The separate portion of antenna elements is selected based on being configured to utilize a bandwidth that meets a threshold bandwidth or matches the bandwidth associated with the application type.

Abstract: Monitoring a MIMO pairing efficiency of a sector to determine whether or not to enable/disable inter-band carrier aggregation. If the pairing efficiency (whether predicted or actual) is high, inter-band carrier aggregation is disabled, and if the pairing efficiency is low, then inter-band carrier aggregation is enabled. The inter-band carrier aggregation utilizes a low-frequency carrier as a primary component carrier and a high-frequency carrier as a secondary component carrier. The MIMO mode of operation utilizes the high-frequency carrier for control transmissions.

Abstract: Ensuring a quality of service for a wireless device attached to an access node by receiving a data packet at a routing node communicably coupled to the access node, wherein the data packet is transmitted by the wireless device to the access node using a bearer that is associated with a first priority level, determining that the data packet is marked with a first quality of service indicator that is associated with a second priority level that is lower than the first priority level, and marking the data packet with a second quality of service indicator that is associated with the first priority level prior to forwarding the data packet to a destination node. The routing node comprises a cell site router configured to receive the data packet from the access node, and the priority levels include QoS parameters such as DSCP and QCI values.

Abstract: Methods, systems, and processing nodes for allocating resources to a control channel based on a number of wireless devices determined to be near a cell edge of an access node. An exemplary method for allocating resources to a control channel includes determining a number of wireless devices that are located near an edge of a coverage area of an access node, and adjusting an amount of resources scheduled in the control channel based on the determined number of wireless devices.

Abstract: Exemplary embodiments described herein include systems, methods, and nodes for selecting a donor for a relay wireless device. Candidate signal arcs of a predetermined angle for a relay wireless device that do not meet an interference criteria are determined. Signals levels are scanned for the relay wireless device for signals received from a plurality of donor access nodes, the scanning iterating over the determined candidate signal arcs that do not meet the interference criteria. Candidate donor access nodes with a received signal level at the relay wireless device that meets a signal level criteria for each candidate signal arc based on the scanning are determined. And a donor access node is selected for the relay wireless device based on the determined candidate donor access nodes.
