Question: How many SC-FDMA symbols are used to transmit the primary sidelink synchronization signal?
Option 1: One SC-FDMA symbol
Option 2: Two adjacent SC-FDMA symbols
Option 3: Four SC-FDMA symbols
Option 4: Eight SC-FDMA symbols
Explanation: The primary sidelink synchronization signal is transmitted in two adjacent SC-FDMA symbols, which allows for efficient use of resources and enables reliable detection by the receiving device.
