Section: 7.7.1 Support of dynamic PTP and PTM switching
Content: For UEs in RRC_CONNECTED, NG-RAN supports dynamic switch between PTP and PTM for MBS as specified in TS 38.300[ NR; NR and NG-RAN Overall description; Stage-2 ]  [2]. In case of split gNB architecture, for a MRB with common PDCP involving both PTP (RLC leg) and PTM (RLC leg), upon receiving the MBS data from the gNB-CU via a shared F1-U tunnel, the gNB-DU makes decision of using PTP (RLC leg) or PTM (RLC leg) or both. For UEs in RRC_INACTIVE only PTM is supported as specified in TS 38.300[ NR; NR and NG-RAN Overall description; Stage-2 ]  [2].
