Abstract: Methods, processing nodes, and systems are provided for managing relay nodes in a wireless network. A number of relay nodes attached to a donor access node can be determined. A number of latency sensitive wireless devices attached to the relay nodes can be determined. A latency sensitive wireless device can be a wireless device running a latency sensitive application. A latency sensitive relay node can be a relay node attached to the donor access node having an attached latency sensitive wireless device. A maximum number of relay nodes attached to the donor access node can be set, for example, based on the number of latency sensitive wireless devices attached to latency sensitive relay nodes.

Abstract: A frame configuration is assigned in a relay enabled communication network. A macro coverage latency is determined. The macro coverage latency is a latency of a communication between the wireless device and a network node when the wireless device is not communicating through the relay node. A relay coverage latency is determined. The relay coverage latency is a latency of a communication between the wireless device and the network node when the wireless device is communicating through the relay node. Based on a comparison of the macro coverage latency and the relay coverage latency, a frame configuration is selected for a communication through the relay node.

Abstract: Methods and systems for adjusting reference signal reporting based on path loss and fading and cell edge conditions experienced by wireless devices in 5G EN-DC networks. As the path loss increases, a period between reference signal reports (or a frequency of reference signal reports) can be increased. This ensures continued quality of service for the wireless devices. Reference signals can include SRS, DMRS, PTRS, etc.

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: 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: 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 a power headroom (PHR) value at a particular wireless device and adjust the CSI reporting frequency when the PHR satisfies a predetermined threshold. The method changes the CSI reporting frequency for the wireless device to enable more frequent CSI reporting over a primary path to the access node to facilitate reallocation of resources.

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.
