First, the technical terms related to the present application will be briefly described.
1. Multimedia Broadcast Multicast Service (MBMS) or Broadcast Multicast Service (MBS)
In the LTE system, MBMS/MBS services can be transmitted in the following two ways:
MBMS/MBS service transmission mode 1: the MBMS service information is transmitted through a Physical Multicast Channel (PMCH) in an MBMS Single Frequency Network (MBSFN) subframe. The Control information is transmitted through system information (such as SIB13) and a broadcast Control Channel (MCCH), and the data is transmitted through a broadcast Traffic Channel (MTCH).
MBMS/MBS service transmission mode 2: and a Physical Downlink Shared Channel (PDSCH) Channel scheduled by a PDCCH (Physical Downlink Control Channel). The Control information is sent through system information (e.g., SIB20) and a Single Cell Multicast Control Channel (SC-MCCH), and the data is sent through a Single Cell Multicast Traffic Channel (SC-MTCH). The SC-MCCH is transmitted through a PDSCH scheduled by a Single Cell Radio Network Temporary Identity (SC-RNTI) PDCCH, and the SC-MTCH is transmitted through a PDSCH scheduled by a G-RNTI (group RNTI) PDCCH.
The MBS service is transmitted through a specific MBMS Radio Bearer (MRB).

2. Centralized Control Unit (CU) and Distributed Unit (DU)

For example, Radio Resource Control (RRC) and Packet Data Convergence Protocol (PDCP) are placed on the CU, and Radio Link Control (RLC) and Media Access Control (MAC)/Physical Layer (PHY) are placed on the DU. The CU and the DU have certain management authority of radio resources. For example, a CU may perform management of its downlink connected cell through an RRC message, and a DU may perform management of its downlink connected cell through a MAC CE (control unit) message. The DUs are connected to 1 CU, and the CUs are connected to the core network and to other CUs.
