In a wireless communication system, user equipment (UE) has autonomy provided by one or more set of rules to handle processing during a measurement gap. UE can ignore or use only a portion of the whole measurement gap if not needed. Thereby, an urgent need for remaining tuned to source carrier frequency can be supported, such as utilizing Random Access Channel (RACH) procedure. UE can also choose to tune to a target carrier frequency supporting timely handovers. Depending on the type of processing required (download shared channel (DL-SCH, UL-SCH, TTI bundling, RACH or SR), the UE may store requests and process the measurements during the gap or ignore the gap measurement as if there were no gaps.
