Question: In a Random Access procedure, what action does the User Equipment (UE) take upon reaching the maximum number of preambles allowed in a cycle during the preamble ramping process?
Option 1: The UE sends an ACK/NACK to the Base Station (BS) and terminates the procedure.
Option 2: The UE initiates a new connection setup, abandoning the current Random Access attempt.
Option 3: The UE pauses for a predetermined backoff period before reinitiating the preamble transmission.
Option 4: The UE repeats the ramping procedure until the maximum number of preamble ramping cycles are reached.
Explanation: Upon reaching the maximum preambles in a cycle, the UE continues by repeating the ramping procedure. This ensures the UE exhausts all attempts before potentially giving up or being instructed otherwise by the network, highlighting persistence in establishing connectivity under radio resource management constraints.
