Question: What are the possible Spreading Factors for an Orthogonal Variable Spreading Factor (OVSF) code used as a Channelisation Code in TDD mode in UTRAN?
Option 1: 2, 4, 8
Option 2: 1, 3, 5, 7
Option 3: 1, 2, 4, 8, 16
Option 4: 4, 8, 16, 32
Explanation: In TDD mode within UTRAN, OVSF codes used as Channelisation Codes can have spreading factors of 1, 2, 4, 8, and 16. These values are crucial for understanding physical channel configuration and management in TDD operations, impacting network capacity and signal processing efficiency.
