Abstract: A system for updating a preferred nodes list for a wireless device in a wireless network includes a server in communication with a plurality of nodes each configured to deploy a radio air interface to provide wireless services to wireless devices. The server includes a processor configured to instruct, in response to a trigger, a first node to send a message to a wireless device connected to the first node. The message instructs the wireless device to contact the server for an updated preferred nodes list. The processor receives a request for the updated preferred nodes list from the wireless device and provides the updated preferred nodes list to the wireless device. The updated preferred nodes list enables the wireless device to change from connecting to the first node included in the preferred nodes list to connecting to a second node included in the updated preferred nodes list.

Abstract: Responsive to determining that a current channel condition of a communication channel improves from an initial channel condition, scheduling data information in a control transmission portion of the communication channel, and responsive to determining that the current channel condition of the communication channel degrades, scheduling control information in the control transmission portion of the communication channel. The scheduling of the data information and the control information is indicated to the wireless device via a reserve bit transmitted on a resource element, versus RRC signaling.

Abstract: Systems and methods are provided for dynamically changing a channel state information (CSI) reporting protocol by adjusting CSI reporting frequency for a wireless device communicating with an access node within a wireless network. The methods and systems identify undesirable signal performance parameters at a particular wireless device and adjust the CSI reporting frequency when the undesirable signal performance parameters meet a predetermined threshold. The method changes the CSI reporting frequency for the wireless device to enable more frequent CSI reporting to the access node to facilitate reallocation of resources.

Abstract: Systems, methods and processing nodes are provided for prioritization of relay data packets. A processor determines one or more of a buffer status for the relay node and a load within the sector, compares the buffer status and/or the load to threshold values, and applies an updated QoS profile to the relay node when the comparisons satisfy particular criteria.

Abstract: Systems, methods, and processing nodes for scheduling resources for relay nodes in a wireless network include identifying a relay node attached to an access node in the wireless network, determining a transmit power associated with the relay node, and prioritizing resources allocated towards the relay node based on the transmit power. The transmit power includes a transmit power of a radio air interface deployed by the relay node.

Abstract: Methods and systems for preventing or delaying handovers to target access nodes that are not configured to provide uplink split mode, include determining that an uplink usage requirement or a power headroom of a wireless device meets a threshold, and preventing handovers of the wireless device to access nodes that are not capable of utilizing uplink split mode. Access nodes capable of utilizing uplink split mode are configured to receive uplink data via at least two different radio access technologies simultaneously, including 4G LTE and 5G NR.

Abstract: Prioritizing resource allocation for relay nodes that have higher bandwidth capabilities, such as 5G EN-DC, versus other relay nodes that do not have such capabilities. The bandwidth capability can be based on a channel bandwidth allocation for different relay nodes, with the assumption that 5G or higher relay nodes will be able to utilize higher bandwidth channels.

Abstract: A method of initiating handover of a wireless device includes determining one or more of a low battery condition, a low power headroom, and a high buffer status of a wireless device. The wireless device can be attached to a first access node deploying multiple radio access technologies over a first coverage area. The method further includes identifying a second access node deploying a single radio access technology over a second coverage area encompassing a location of the wireless device, and initiating handover of the wireless device from the first access node to the second access node based at least in part on the one or more of the low battery condition, low power headroom, and high buffer status of the wireless device. Systems and devices relate to initiating handover of a wireless device.

Abstract: Systems and methods are provided for dynamically triggering a handover of a wireless device based on a throughput measurement of a source node and a target node on a primary path. The method includes comparing the first throughput measurement at the source access node for the primary path to the second throughput measurement at the target access node or comparing both throughput measurements to predetermined criteria and making a handover determination for the wireless device based on the comparison.
