Processing measurement gaps in a wireless communication system
First Claim
1. A method for processing a measurement gap, comprising:
- receiving a radio resource control (RRC) assignment on a downlink for a measurement gap for tuning from a source carrier frequency to a target carrier frequency;
determining a scheduling conflict arising from a beginning portion of a transmission time interval (TTI) bundle colliding with the measurement gap, an end portion of a TTI bundle colliding with the measurement gap, or an entire TTI bundle colliding with the measurement gap; and
performing a medium access control (MAC) process in accordance with a protocol predefined for the scheduling conflict by transmitting a portion of the TTI bundle that does not overlap with the measurement gap and canceling the colliding portion.

Abstract
In a wireless communication system, user equipment (UE) is provided, one or more set of rules are provided for the UE to handle the processing during a measurement gap. In some aspects, the gap measurement may be ignored. In some aspects, the processing is stored and handled at a later in time and gap measurements are performed. Depending on the system, the measurements performed during the gaps may be UE implementation dependent, wherein the UE determines whether to perform the measurement for a given gap. In some instances, the UE may not perform measurements during the gap, thereby giving priority to other processing, such as RACH processing. Depending on the type of processing required (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.
