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.

Abstract: A multi-subscriber identity module (SIM) multi-standby user equipment (UE) improves recovery of an original operation of a first radio access technology (RAT) when the UE tunes away from the first RAT. In some instances, the UE communicates with the first RAT on a transmit chain and a receive chain and then tunes to a second RAT on the receive chain to monitor downlink communications or activities of the second RAT. The UE transmits on the first RAT over the transmit chain, while tuned to the second RAT. Thus, the UE continues to perform uplink transmission when the UE tunes away, which allows a base station of the first RAT to track the UE for downlink beam-forming.

Abstract translation: 当多用户识别模块（SIM）多待机用户设备（UE）远离第一RAT时，提高了第一无线电接入技术（RAT）的原始操作的恢复。 在一些情况下，UE在发射链和接收链上与第一RAT通信，然后调谐到接收链上的第二RAT，以监视第二RAT的下行链路通信或活动。 当UE在调谐到第二RAT时，通过发送链在第一RAT上进行发送。 因此，当UE调谐离开时，UE继续执行上行链路传输，这允许第一RAT的基站跟踪UE以进行下行链路波束形成。

Abstract: A method of wireless communication includes determining whether a serving cell signal strength is below a first threshold. The method also includes determining whether an inter/intra frequency neighbor cell signal strength is below a second threshold. The method further includes determining whether a number of idle traffic time slots for inter-radio access technology IRAT measurements is less than a third threshold. Finally, a frequency of IRAT measurements in time slot zero (TS0), a downlink pilot time slot (DwPTS), an uplink pilot time slot (UpPTS), and a gap (GP) is increased. The increase is based on the determined serving cell signal strength, the determined inter/intra frequency neighbor cell signal strength, and the determined number of idle traffic time slots.
