In some aspects, a network controller of a wireless communication system may receive a time-sensitive network (TSN) traffic configuration that indicates a duration of a gate open state for a TSN traffic flow and a periodicity with which the gate open state occurs; configure one or more quality of service (QoS) parameters, associated with the wireless communication system, for a QoS flow that is to carry the TSN traffic flow, wherein the one or more QoS parameters are configured based at least in part on one or more TSN capability parameters associated with the network controller and at least one of the duration of the gate open state or the periodicity; and transmit the one or more QoS parameters to a base station of the wireless communication system. Numerous other aspects are provided.
