Question: In a 5G New Radio (NR) environment, during an intra-frequency handover for a 2 Rx Reduced Capability (RedCap) User Equipment (UE), what is the maximum allowed time for the UE to start transmitting the Physical Random Access Channel (PRACH) to the target cell (Cell 2) after the specified trigger?
Option 1: Less than 50 ms from the beginning of the handover process
Option 2: Exactly 72 ms from the start of the handover initiation
Option 3: More than 100 ms after the handover command is received
Option 4: Less than 72 ms from the beginning of time period T3
Explanation: This answer reflects the timing requirement for intra-frequency handovers involving RedCap UEs, ensuring timely PRACH transmission to the target cell for efficient handover execution and service continuity. This constraint balances handover success rates with swift resource reallocation.
