CONTENTION WINDOW UPDATES WITH INTEGRATED ACCESS AND BACKHAUL NODES FOR UNLICENSED OPERATIONS

Abstract:

Methods, systems, and devices for wireless communications are described. An integrated access and backhaul (IAB) system may perform contention window updates on an IAB node for different components of the IAB node. In some implementations, the IAB node may perform separate contention window updates in separate reference durations for the different components. Additionally or alternatively, the IAB node may perform a joint contention window update for the different components, where a single reference duration for updating contentions windows for the components may be defined for the IAB node that includes transmissions for both components. Additionally or alternatively, the IAB node may perform separate contention window updates for the different components based on the single reference duration that includes transmissions for both components, where feedback may be used separately to update corresponding contention windows.
