Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message indicating multiple contention-based resource sets dedicated for the transmission of scheduling requests, where each contention-based resource set is associated with one or more respective contentions. The one or more respective conditions may be associated with a packet delay threshold, a buffer size threshold, or a probability function. The UE may transmit a scheduling request to request uplink resources for the UE using a resource of a contention-based resource set based on satisfaction of the one or more respective conditions of the contention-based resource set. In some examples, a remaining packet delay budget of an uplink message at the UE may satisfy the packet delay threshold of the contention-resource set. As such, the UE may randomly select the resource, from the contention-based resource set, to use for transmission of the scheduling request.
