Summary of Agreements by Topic

Mechanisms to Support Group Scheduling for RRC_CONNECTED UEs

1. FDMed Unicast and Group-Common PDSCH Capability:

2. Collision Handling Between SPS and Dynamic Scheduling:
• Agreed on handling collisions between SPS and dynamic scheduling PDSCHs for multicast.
3. Broadcast PDCCH Monitoring:
• Defined monitoring occasions for broadcast PDCCH in active DL BWP.
4. Rate Matching Pattern for Broadcast:
• Clarified the number of rate matching patterns for MBS broadcast reception.
5. Joint Release of Multiple Multicast SPS:
• Multicast DCI cannot be used for joint SPS unicast and SPS multicast release or joint SPS unicast release.
