1. A method performed by a first node for mapping Time-Sensitive Networking, TSN, streams, to one or more 5G Quality of Service, QoS, flows, the method comprising:
receiving traffic class specific information for one or more TSN streams; and
determining a set of the one or more 5G QoS flows to support a traffic class based on the received traffic class specific information;
the method further comprising:
establishing a set of 5G QoS Identifier, 5QI, table entries for which different values are determined independent of knowing which TSN streams will map to any given traffic class; and
upon receiving the TSN traffic class specific information, mapping corresponding TSN streams into subgroups where each subgroup is supported by a common 5G QoS flow having values indicated by its corresponding 5QI table entry;
wherein each 5G QoS flow used to support each subgroup is selected such that it ensures a PDB requirement and the maximum payload volume per transmission instance of the corresponding subgroup are satisfied.
