In some aspects, an access node may synchronize a clock of the access node which is associated with communication on a local area network to a frame structure of a time-synchronized wireless network. The access node may receive configuration information relating to a quality of service profile and a first set of time intervals for the clock of the access node. The access node may map the first set of time intervals for the clock of the access node to a second set of time intervals of the frame structure of the time-synchronized wireless network. The access node may communicate on the time-synchronized wireless network during one or more of the second set of time intervals. Numerous other aspects are provided. ## Claims ### Claim 1 A method of wireless communication performed by an access node, comprising: synchronizing a clock of the access node to a frame structure of a time-synchronized wireless network, wherein the clock is associated with communication on a local area network that implements a Time Sensitive Networking (TSN) protocol;
