Section: 7.7.2.3 Support of resource efficiency for RAN Sharing with multiple cell-ID broadcast
Content: gNB-DUs sharing the same physical cell resources receive via F1-C information enabling identifying broadcast MBS sessions providing identical content. The identification is based on Associated Session ID, for location dependent MBS services, the MBS Service Area is also taken into account. Applying resource efficiency for RAN Sharing with multiple cell-ID broadcast - resolve different QoS requirements received from the participating 5GCs in an implementation specific way. - F1-U resources are established towards either all involved gNB-CUs or only some of them which is decided by the entity controlling the involved gNB-DUs sharing the same physical cell resources. The gNB-DU is able to trigger the gNB-CU to establish F1-U resources. - the gNB-CU-CP takes into account the decision F1-U resources have been established or not to decide whether to establish NG-U resources.
