Question: What action is taken by the User Equipment (UE) when the maximum number of preamble transmission counter is reached for a random access procedure on a target cell?
Option 1: The UE automatically selects a new target cell for the random access procedure.
Option 2: The UE indicates a Random Access problem to its upper layers.
Option 3: The UE adjusts the NPRACH transmission power and retries the preamble transmission.
Option 4: The UE initiates a handover to a different Radio Access Technology (RAT).
Explanation: When the maximum number of preamble transmissions is reached without success, the UE notifies higher layers of this issue. This allows for potential reconfiguration or alternative actions to resolve the Random Access problem, ensuring efficient resource use and maintaining connectivity.
