A method and system for dynamically controlling connectivity of a user equipment device (UE) when the UE has standalone connectivity with a first access node under a first radio access technology (RAT). An example method includes the UE detecting that the UE is within threshold strong coverage of a second access node under a second RAT, and the UE making a selection between (i) responsively handing over from the first access node to the second access node and (ii) having dual-connectivity with the first access node and the second access node. Further, the example method includes the UE informing the first access node of the UE's selection, perhaps together with an inter-RAT measurement report reporting that the UE is within threshold strong coverage of the second access node, and the first access node responsively taking action in accordance with the UE's selection.

UE-controlled selection between inter-RAT handover and inter-RAT dual connectivity

A method and system to control configuration of a narrowband carrier within frequency bandwidth of a wideband carrier, where the frequency bandwidth of the wideband carrier defines a plurality of frequency segments. An example method includes selecting one of the frequency segments of the frequency bandwidth of the wideband carrier on which to define the narrowband carrier, with the selecting being based on the one frequency segment having a lowest level of noise among the plurality of frequency segments. And the example method may then further include, based on the selecting, configuring the narrowband carrier on the selected frequency segment of the frequency bandwidth of the wideband carrier rather than on another frequency segment of the plurality of frequency segments.

Use of noise as a basis to control configuration of narrowband carrier within wideband carrier

A wireless communication device optimizes network communications for a user application. The wireless communication device generates network characteristics for multiple wireless communication networks based wireless signals received from the multiple wireless communication networks. The wireless communication device transfers the network characteristics for the multiple wireless communication networks to the user application. The wireless communication device receives a selection of one of the wireless communication networks from the user application based on the network characteristics. The wireless communication device communicates over a radio with the selected one of the multiple wireless communication networks responsive to the selection from the user application.

Wireless communication network optimization for user applications in wireless user equipment (UE)

A wireless communication system determines a first network slice and a second network slice to serve a user application. The wireless communication system identifies a performance level for the first network slice to serve the user application. The wireless communication system exchanges first user data using the first network slice to serve the user application. The wireless communication system determines actual performance of the first network slice to serve the user application. The wireless communication system compares the actual performance of the first network slice to the performance level for the first network slice, and in response, stops the exchange of the first user data to serve the user application using the first network slice and starts an exchange of second user data to serve the user application using the second network slice.

Network slicing in a wireless communication network

Systems and methods are provided for optimizing layer assignment to UEs that are currently on an LTE network, or that are experiencing EPS fallback and are moving from 5G to LTE. Instead of blindly assigning a UE an LTE layer or assigning the same layer to all UEs, aspects provided for an intelligent and dynamic selection of an LTE layer for each UE. The network may analyze one or both of layer compatibility information and historical data associated with the UEs. With this information, the network assigns an LTE layer to each UE.

Optimizing layer assignment during EPS fallback procedures

Methods and systems for preventing or delaying handovers to target access nodes that have limited carrier aggregation capabilities, in dual-connectivity (EN-DC) wireless networks, by adjusting handover thresholds to delay the handover of the wireless device to the target access node, for wireless devices reporting high uplink buffer sizes.

Delaying handovers in 5G EN-DC networks based on carrier aggregation capabilities

A wireless communication network handsover a wireless User Equipment (UE). The wireless communication network selects a network slice for the wireless UE. The wireless communication network selects handover criteria for the wireless UE based on the selected network slice. The wireless communication network serves the wireless UE over a source Radio Access Network (RAN) and the selected network slice. The selected network slice detects a UE handover from the source RAN to a target RAN based on the handover criteria, and in response, the wireless communication network serves the wireless UE over the target RAN and the selected network slice.

Systems and methods are provided for dynamically disabling beamforming for particular user devices. At a node that utilizes carrier aggregation, a node, such as an eNodeB or a gNodeB, communicates with a user device that is located at a cell edge, the communicating comprising transmitting data on at least two channels that utilize beamforming. Performance of the user device is determined to be below a predetermined threshold. When this occurs, beamforming capabilities are disabled for at least one of the at least two channels used to communicate with the user device.

Dynamically disabling beamforming capabilities

A system and method of managing network bandwidth is provided, in which one or more utilization thresholds are set for an access node, wherein the access node is configured to communicate using a band consisting of a first portion corresponding to communication in a first communication mode and a second communication mode and a second portion corresponding to communication in the first communication mode but not the second communication mode; and one or more utilization parameters are monitored and compared to the corresponding utilization threshold(s). Based on the comparison, the sizes of the portions may be modified and/or wireless devices seeking to join the network may be appropriately assigned.

Spectrum management for DSS-based networks

5G relay nodes attached to millimeter wave carriers (whether standalone or EN-DC) may suffer from poor quality of service due to intermodulation distortion at the donor access node. The relay node is instructed to attach to a lower-frequency carrier, or a different donor access node. The lower-frequency carrier can include another 5G carrier deployed by the same donor access node, or a 4G carrier or any other carrier.

Ensuring quality of service for relay nodes

Dynamically limiting MIMO transmission layers assigned to wireless devices to mitigate uplink noise levels measured at an access node (e.g. RSSI). The transmission layers can be adjusted based on a device capability or power class. For example, maximum MIMO transmission layers assigned to HPUEs can be reduced first.

Limiting uplink noise by adjusting MIMO transmission layers

A method and system to control transport block size (TBS) that a user equipment device (UE) served by an access node will use for uplink air-interface transmission from the UE to the access node, the TBS defining a quantity of data that the UE will provide in the uplink air-interface transmission. An example method includes (i) determining a rate of uplink backhaul packet loss of the backhaul interface and (ii) using the determined rate of uplink backhaul packet loss as a basis to control what TBS the UE will use for the uplink air-interface transmission.

Use of backhaul packet-drop rate as basis to control transport block size for air-interface communication

A method and system for controlling uplink-path switching of a user equipment device (UE) when the UE has at least two co-existing air-interface connections including a first air-interface connection with a first access node and a second air-interface connection with a second access node, and where one of the first and second air-interface connections defines a primary uplink path of the UE. An example method includes (i) predicting that the UE's second air-interface connection will be lost and (ii) responsive to at least the predicting that the UE's second air-interface connection will be lost, but before the predicted loss occurs, forgoing application of at least a portion of an uplink-path-switch control process for dynamically controlling whether to reconfigure the UE from having the first air-interface connection be set as the UE's primary uplink path to having the second air-interface connection be set as the UE's primary uplink path.

Prediction of connection loss as basis to control primary uplink path of dual-connected device

A method and system to dynamically reassign RF spectrum from a first access node to a second access node, where the first access node provides service on a first carrier having a carrier bandwidth. An example method includes (i) selecting a frequency portion of the carrier bandwidth to reassign, the selecting being based on the frequency portion having higher determined noise than one or more other frequency portions of the carrier bandwidth, and (ii) based on the selecting, reassigning the selected frequency portion from the first access node to the second access node to be used by the second access node as at least part of a second carrier on which to provide service. Upon reassigning of the selected frequency portion, the second access node could then provide service on the reassigned portion and the first access node could continue to provide service on a remainder of the first carrier.
