Section: 5.7.7 PDU Set QoS Parameters 5.7.7.1 General
Content: PDU Set QoS Parameters are used to support PDU Set based QoS handling in the NG-RAN. At least one PDU Set QoS Parameter shall be sent to the NG-RAN to enable PDU Set based QoS handling. The following PDU Set QoS Parameters are specified: 1. PDU Set Delay Budget (PSDB). 2. PDU Set Error Rate (PSER). 3. PDU Set Integrated Handling Information (PSIHI). For a given QoS Flow, the values of PSDB, PSER and PSIHI can be different for UL and DL. The QoS Profile may include the PDU Set QoS Parameters described in this clause (see clause 5.7.1.2) for UL and/or DL direction. The PCF determines the PDU Set QoS Parameters based on information provided by AF and/or local configuration. The PDU Set QoS parameters are sent to the SMF as part of PCC rule. The SMF sends them to NG-RAN as part of the QoS Profile. If the NG-RAN receives PDU Set QoS Parameters, it enables the PDU Set based QoS handling and applies PDU Set QoS Parameters as described in TS 38.300[ NR; NR and NG-RAN Overall description; Stage-2 ]  [27], TS 38.413[ NG-RAN; NG Application Protocol (NGAP) ]  [34] and TS 38.331[ NR; Radio Resource Control (RRC); Protocol specification ]  [51].
