Abstract: Systems and methods for fine ranging (FiRa) slot scheduling in ultra-wideband (UWB) enabled devices are disclosed. In particular, a control circuit may allocate slots within a UWB data phase based on required quality of service (QOS) parameters. More particularly, a control circuit may set up one or more connections based on connection requests that are accompanied by QoS indicators. The control circuit may then allocate slots according to the QoS indicator, where slots are initially allocated to connections with the highest QoS indicator and then allocated through connections with increasingly lower QoS indications. In this manner, the QoS guarantees are satisfied, improving the overall user experience.

Abstract: Systems and methods for fine ranging (FiRa) link layer control in ultra-wideband (UWB) enabled devices are disclosed. In one aspect, a link layer control plane acts as a black box to an application developer requiring minimal inputs therefrom, but allows connections to be created, paused, resumed, and/or deleted as needed or desired. Exemplary inputs include a qualify of service indicator, target bitrate, disorder metrics, maximum burst size and the like. By implementing aspects of the present disclosure, an application developer does not have to allocate UWB resources, simplifying the design process for the application developer. Further and more specifically, exemplary aspects of the present disclosure allow the link layer to establish, stop, or resume connections and high-level requests from an application may be translated into MAC or link layer parameters.
