1. A method performed by one or more network nodes of a cellular communications system, the cellular communications system operating as a virtual Time-Sensitive Networking, TSN, bridge of a TSN network, the method comprising:
providing, to a controller associated with the TSN network, two or more parameters that relate to capabilities of the virtual TSN bridge, wherein the two or more parameters that relate to the capabilities of the virtual TSN bridge comprise:
a first parameter that defines a clock accuracy and a minimum value of periodicity of an entity in the cellular communications system that operates gating control for the virtual TSN bridge; and
a second parameter that informs whether the controller associated with the TSN network that the virtual TSN bridge or a particular egress port of the virtual TSN bridge is restricted to exclusive gating or is not restricted to exclusive gating, wherein exclusive gating means that only frames belonging to a single TSN traffic class are transmitted from egress ports of the virtual TSN bridge or the particular egress port of the virtual TSN bridge at a given time.
