Question: What initializes the pseudo-random sequence generator for reference-signal sequences in E-UTRA?
Option 1: Slot number within a radio frame
Option 2: OFDM symbol number within the slot
Option 3: c_init, which is computed at the start of each OFDM symbol
Option 4: Radio frame number
Explanation: The pseudo-random sequence generator for reference-signal sequences in E-UTRA is initialized with c_init, which is computed at the start of each OFDM symbol. This ensures that the pseudo-random sequence is generated consistently and predictably, allowing for accurate synchronization and channel estimation in wireless communication systems.
