Abstract

Aspects of the methods and apparatus include determining that a time-to-trigger (TTT) timer has expired, and determining that a serving radio access technology (RAT) received signal characteristic is less than a signal characteristic threshold when the TTT timer has expired. Further, the aspects include determining, in response to the serving RAT received signal characteristic being less than the signal characteristic threshold, that a target RAT frequency measurement associated with a Measurement Report Message (MRM) for performing an inter-RAT (IRAT) handover cannot be completed within a time limit according to a current measurement gap configuration. Also, the aspects include calculating a measurement gap duration sufficient to complete the target RAT frequency measurement associated with the MRM for performing the IRAT handover, and configuring a new measurement gap prior to the time limit, wherein the new measurement gap comprises the calculated measurement gap duration.
