Abstract: Attaching to additional access nodes and performing handovers responsive to path loss measurements and uplink transmit power levels meeting different thresholds. A wireless device attached to a first access node is experiencing one or more of a threshold path loss or a threshold uplink transmit power is instructed to enable dual connectivity, wherein the wireless device remains attached to the first access node. Embodiments include 5G EN-DC systems that are collocated or distributed.

Abstract: Performing inter-band carrier aggregation based on device capability includes monitoring a dominant type of wireless devices in a wireless sector based on whether or not they are capable of inter-band carrier aggregation, and enabling or disabling inter-band carrier aggregation in the sector based on the dominant type. Enabling/disabling inter-band carrier aggregation can include allowing or preventing usage of usage of a low-frequency carrier as a primary component carrier aggregated with a high-frequency carrier as a secondary component carrier. Carriers using FDD and TDD duplexing modes are included.

Abstract: Selecting combinations of antennae of a wireless device based on transmission type includes determining a transmission type of a transmission between the wireless device and an access node and, based on the transmission type, instructing the wireless device to utilize different antenna configurations, including 5G EN-DC, MIMO, mm-wave, and other combinations. The different antenna configurations comprise different combinations of antennae of the wireless device.

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: 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: Dynamically limiting uplink transmit power of wireless devices that are known to be within range of a dense cluster or quantity of access nodes. Wireless devices can report identifiers of nearby access nodes. Responsive to determining a large quantity of identifiers from a wireless device in a specific location, the maximum allowable transmit power of the wireless device (or other wireless devices in the same area) can be reduced Power can be reduced for HPUEs as well as LPUEs.

Abstract: Load balancing based on pairing efficiency and channel bandwidth includes comparing pairing efficiency metrics of wireless devices attached to different wireless air interfaces, comparing an aggregate channel bandwidth of carriers using each wireless air interface, and offloading wireless devices from one carrier to another carrier based on the comparisons of the pairing efficiency metrics and the aggregate channel bandwidth. In an embodiment, wireless devices are offloaded from a 5G NR wireless air interface to a 4G LTE wireless air interface having a higher pairing efficiency and aggregate channel bandwidth.

Abstract: Methods and systems for selecting donor access nodes for relay nodes capable of 5G EN-DC, based on conditions measured at a wireless backhaul between the relay nodes and donor access nodes, or a mobile backhaul between a cell site router and a core network. Mobile backhaul conditions can include a packet loss at a cell site router, and wireless backhaul conditions can include interference in a wireless air interface. The interference may be measured for specific portions of resources of the wireless air interface, and the specific portions may be correlated with radiofrequency (RF) channels deployed by each candidate donor access node.
