Hello Lucas No, there are multiple QUIC connections (multipath!). Please see slide #5 in https://github.com/quicwg/wg-materials/blob/master/interim-20-10/Multipath%20in%203GPP%20ATSSS.pdf
Bulk data and low-latency are kept separate. Each QoS flow has its own connection.

Part of the is the type of PDU session, such as multiaccess-PDU with steering mode information (e.g. load balancing, active-standby, etc. see the presentation for more details). The MP-QUIC connection is established per IP flow (5 tuple). With this information the UE will steer the traffic to the corresponding multipath-quic connection. I don't follow, sorry. If a single IP flow carrying QUIC is used for multiplexing both low-latency and bulk data, how do you resolve this? Cheers Lucas
