Question: What is the purpose of exchanging MBS FSA ID(s) between neighboring gNBs in NR MBS?
Option 1: To enable UE-based beamforming
Option 2: To facilitate handover procedures
Option 3: To optimize cell-specific scheduling
Option 4: To support MBS frequency layer prioritization for MBS broadcast sessions
Explanation: The exchange of MBS FSA ID(s) between neighboring gNBs is necessary to support MBS frequency layer prioritization, which enables the network to prioritize certain frequencies for MBS broadcast sessions. This information helps the gNBs to make informed decisions about frequency allocation and resource management, ultimately improving the overall performance and efficiency of the NR MBS service.
