1. A network node configured to communicate with a wireless device via an access network, the network node comprising:
processing circuitry configured to:
receive at least one parameter from a core network node, the at least one parameter indicating a level of synchronization accuracy that is required for a time sensitive network, TSN, clock in a TSN; and
implement one of a plurality of methods in the access network for distributing access network clock information to the wireless device and for determining downlink propagation delay information based on the level of synchronization accuracy for the TSN clock, each one of the plurality of methods being associated with a different level of synchronization accuracy for an access network clock, the TSN clock being based on the access network clock.
