Section: 6.2.5.1.1.3 Derived QoS rules
Content: Derived QoS rules are applicable only for PDU session of IPv4, IPv6, IPv4v6 or Ethernet PDU session type. The reflective QoS in the UE creates derived QoS rules associated with a PDU session based on DL user data packets received via the PDU session. Each derived QoS rule contains: a) a QoS flow identifier (QFI); b) a packet filter for UL direction; and c) a precedence value of 80 (decimal). NOTE: On the network side, the corresponding QoS rule can be associated with a different precedence value in the range from 70 to 99 (decimal). Within a PDU session: a) there can be zero, one or more derived QoS rules associated with a given QFI; and b) there can be up to one derived QoS rule associated with a given packet filter for UL direction. In the UE, a timer T3583 runs for each derived QoS rule. Reflective QoS is not supported in NB-N1 mode. Reflective QoS is not applicable for a PDU session with control plane only indication.
