Abstract: This disclosure describes techniques that can be used for dynamic link adaptation in wireless telecommunications networks. Some implementations relate to determine signal to interference and noise (SINR) back off values, which can be used to determine adjustments to transmission characteristics such as transmission power for improving throughout. In some implementations, block error rates are used to determine adjustments to transmission power. In some implementations, slot-specific adjustments are determined. Reinforcement learning can be used to determine adjustments in real time or nearly real time.

Abstract: A method can include receiving atmospheric data comprising atmospheric parameters. A method can include receiving current cell site configuration data of one or more cell sites of a wireless telecommunications network. A method can include applying a machine learning model to the atmospheric data and the current cell site configuration data to predict a tropospheric ducting event, wherein the model is trained using supervised learning performed using historical atmospheric and cell site configuration data as inputs and historical tropospheric ducting events as outputs. A method can include determining a likelihood of a tropospheric ducting event affecting a cell site among the one or more cell sites in a geographic area. A method can include determining a mitigation action to perform at the cell site, wherein implementing the mitigation action at the cell site effectuates reduction in an impact of the predicted tropospheric ducting event at the cell site.

Abstract: A method and system for dynamically controlling connectivity of a user equipment device (UE) in a wireless communication system. An example method includes (i) while the UE has dual connectivity with a first access node and a second access node, determining that power headroom of the UE on an air-interface connection between the UE and the second access node is threshold low, and (ii) responsive to at least the determining, transitioning the UE from having the dual connectivity with the first access node and the second access node to instead having standalone connectivity with the second access node. Transitioning the UE to having standalone connectivity with the second access node as to which the UE had threshold low power headroom may help to improve quality of communication between the UE and the second access node.
