Question: In E-UTRAN, how is multiplexing of transport channels using MBSFN (Multicast-Broadcast Single Frequency Network) and non-MBSFN transmission achieved?
Option 1: On a per-sub-frame basis, allowing flexible allocation within a frame.
Option 2: Exclusively on dedicated MBSFN frames, separating MBSFN and non-MBSFN traffic entirely.
Option 3: Through static allocation, where MBSFN is always assigned to the first half of the frame.
Option 4: Dynamically based on UE (User Equipment) density in the cell.
Explanation: This correct answer reflects the flexibility in E-UTRAN's design for handling both MBSFN and non-MBSFN transmissions. By allowing multiplexing on a per-sub-frame basis, the network can efficiently manage resources, allocating subframes to either type of transmission as needed. This approach supports the scalable and dynamic nature of wireless communications, especially in scenarios where multicast/broadcast services (utilizing MBSFN) coexist with unicast traffic (non-MBSFN).
