Question: In a TDD (Time Division Duplex) network, what is the primary factor influencing the cell re-selection delay, aside from the maximum time to read BCCH (Broadcast Control Channel) data from a GSM cell?
Option 1: Signal strength of neighboring cells
Option 2: Additional delay caused by the random access procedure
Option 3: Type of User Equipment (UE) used
Option 4: Number of concurrent handovers in the network
Explanation: The cell re-selection delay in a TDD network is significantly impacted by the additional delay caused by the random access procedure. This procedure introduces variability and overhead, affecting how quickly a device can complete the cell re-selection process. Understanding this is crucial for optimizing network performance and user experience, especially in scenarios requiring swift handovers.
