Abstract: A method and system for dynamically controlling random-access-request transmission in a cell provided by an access node, the access node supporting access attempts by user equipment devices (UEs). An example method includes (i) determining an extent to which the cell has experienced access blocks due to connection-request communication failure after successful random-access transmission and (ii) using the determined extent as a basis to dynamically set a physical random access channel (PRACH) format of the cell, wherein the PRACH format defines one or more configuration settings for random-access-request transmission by UEs in the cell and correlates with an effective radius of the cell.

Abstract: A method and system for controlling data split of a dual-connected 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. An example method includes (i) comparing an aggregate frequency bandwidth of the first air-interface connection with an aggregate frequency bandwidth of the second air-interface connection, (ii) based at least on the comparing, establishing a split ratio that defines a distribution of data flow of the UE between at least the first air-interface connection and the second air-interface connection, and (iii) based on the establishing, causing the established split ratio to be applied. Further the method could include using the comparison as a basis to set one of the UE's air-interface connections as the UE's primary uplink path.

Abstract: A method and system to help prevent legacy devices that do not support a service feature such as uplink-downlink subcarrier shifting from connecting with an access node on a carrier where the service feature should be applied. An example method involves use of Network Signaling (NS) values that are used for spectral emission control. Per the disclosure, the access node could broadcast an NS value that legacy device are not configured to understand but that newer devices are configured to understand as relating to both spectral emission limitation and also the service feature at issue. Responsive to the broadcast of that NS value, the legacy devices will therefore not connect with the access node, while the newer devices may connect with the access node and apply the service feature.

Abstract: 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.

Abstract: In a system where a first node provides a first area of TDD coverage on a first TDD carrier using a first TDD configuration and an adjacent second node provides a second area of TDD coverage on a second TDD carrier using a different second TDD configuration, the first node could additionally provide an area of FDD coverage on a first FDD carrier, including causing the area of FDD coverage to sit at least partially between the first and second areas of TDD coverage and therefore to define a spatial buffer between the first and second areas of TDD coverage. For instance, the first access node could restrict its service on the first TDD carrier to be for user equipment devices (UEs) that are relatively close to the first access node and could restrict its service on the first FDD carrier to be for UEs that are relatively far away from the first access node.

Abstract: A method and system for controlling wireless service of a user equipment device (UE) by an access node. The access node serves the UE with uplink carrier-aggregation over a connection encompassing multiple uplink channels including a primary uplink channel (uplink PCell) and a secondary uplink channel (uplink SCell). Further, the access node dynamically sets a channel-quality threshold applicable to control when to deconfigure the uplink SCell from service of the UE, with the dynamically setting of the channel-quality threshold including setting the channel-quality threshold to a value selected based on one or more operational circumstances of the UE, such as whether the UE is engaged in uplink heavy or rather uplink light communication. And the access node applies the dynamically set channel-quality threshold to control when to deconfigure the uplink SCell from service of the UE.

Abstract: A method and system for controlling how many carriers to aggregate together for carrier-aggregation service of a UE. A base station could take into account how many MIMO layers a UE would support respectively for each of various candidate quantities of carriers, and the base station could select the candidate quantity of carriers that would result in use of a highest aggregate total number of MIMO layers. Further, the selection could involve mapping UE-reported rank to a quantity of carriers, with the rank being inversely proportional to the selected quantity of carriers. The base station could then configure carrier-aggregation service of the UE with the selected quantity of carriers.

Abstract: A method and system for dynamically controlling connection-request transmission in a cell provided by an access node, the access node supporting access attempts by user equipment devices (UEs), each access attempt including the UE engaging in random access signaling with the access node and the UE then engaging in up to a maximum allowed number of connection-request transmissions to the access node in an effort to ensure successful receipt by the access node of a connection request from the UE, where an access block occurs if the access node does not successfully receive connection-request transmission from the UE through the maximum allowed number connection-request transmissions. An example method includes (i) determining an extent to which the cell has experienced such access blocks and (ii) using the determined extent as a basis to dynamically set a maximum allowed number of connection-request transmissions per access attempt in the cell.

Abstract: When a first radio of a UE has an air-interface connection with an access node on a first carrier and the UE encounters a trigger for the UE to scan for and report to the access node coverage on a second carrier, a second radio of the UE, rather than the first radio of the UE, will conduct the scanning, and the first radio of the UE will then report to access node over the air-interface connection on the first carrier a result of the scanning conducted by the second radio. Optimally, the first radio of the UE thus need not tune away from its air-interface connection with the access node in order for the UE to scan for target coverage on the second carrier. And the process could thereby help avoid the interruption of communication between the UE and the access node on the air-interface connection over the first carrier.

Abstract: A method and system for controlling air-interface connectivity of a user equipment device (UE). A computing system detects, when the UE has dual connectivity including a first air-interface connection with a first access node and a second air-interface connection with a second access node, and when the first air-interface connection is defined on a first carrier, that the UE is moving toward a geographic area where UEs that were served by the first access node on the first carrier as part of dual connectivity lost their dual connectivity due to their having insufficient aggregate dual-connectivity throughput. And based at least on the detecting, the computing system reconfigures the first air-interface connection of the UE's dual connectivity to be defined on a lower-frequency second carrier, to help avoid having the UE lose its dual connectivity.
