- Those services with the same QoS requirements of BLER (Block Error Rate) (e.g., having the same modulation coding scheme) can be multiplexed into one MAC PDU (Media Access Control - Protocol Data Unit). This is called statistical multiplexing. All services multiplexed into one MAC PDU are defined as a service group.

- MCE can determine MCS information and MSAP information. The subframes scheduled for the MBMS service or the MBMS service group will not exceed the subframe range allocated by the MBSFN subframe indicated by the MSAP information.
- the MSAP information is used to limit the range of subframes for MBSFN transmissions for each MBMS service or group of services. For example, if there are three subframes defined for one MBMS service in the MSAP of one scheduling period, this means that for this MBMS service, the subsequent dynamic scheduling will not exceed three subframes.
- the determined semi-static MBMS scheduling information is notified by the MCE to each base station in the MBSFN area and the corresponding mobile station controlled by each base station.
- Figure 2 is a timing diagram of the process of notifying semi-static MBMS scheduling information from the MCE to the base station and the corresponding mobile station controlled by the base station via the M2 interface and the Uu interface.
- the semi-persistent scheduling information is transmitted from the MCE to each base station in the MBSFN area via the M2 interface between the MCE and the eNB, for example, via MBMS scheduling information.

- each 6NB MAC layer will perform dynamic scheduling according to the actual processing data of each MBMS service or service group waiting for the current scheduling period.
- Subframes for each MBMS service or service group in the MSAP are based on QoS requirements, but the actual service data can be bursty, The amount of processing per cycle will also be variable.

- the total number of MBSFN subframes in a scheduling period is 12, as shown in Figure 5.
- the MSAP for these services is determined by the MCE.
- the MCE also determines the transmission order of these services or service groups based on their QoS requirements such as priority, delay, and so on. For example, the transmission order here is ⁇ S3, Sl, S5 ⁇ , S4, S2, where the service group is treated as a service, but in the service group, these MBMS services have their own internal order.

- the eNB then transmits the semi-static MBMS scheduling information to the UE through the Liu interface using RRC signaling (including MBMS modification service information, MBMS unmodified service information, and current cell PTM RB information).
- the eNB performs dynamic scheduling of the MAC layer according to the actual amount of data processed in the scheduling period. For example, for the MBMS service group, S3 occupies 2.5 subframes, S 1 occupies 1.3 subframes, and S5 occupies 2.5 subframes; for MBMS service, S4 occupies 1.6 subframes; and S2 occupies 2 subframes frame.

- the actual dynamic scheduling result for these five services will be the end position index of the MBSFN subframe for each MBMS service, 3 for S3, 4 for S1, 6 for S5, and 9 for S4. 12 for S2.
