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: The present disclosure presents a method and an apparatus for network cognizant uplink transmissions during inter radio access technology (IRAT) handovers. For example, the method may include skipping inter radio access technology (IRAT) measurements during one or more dedicated channel (DCH) measurement occasion (DMO) or idle interval gaps of a transmission timing interval (TTI). The method further includes transmitting data on an uplink from a user equipment (UE) to a network entity during the entire duration of the TTI and determining whether the network entity is decoding the data transmitted on the uplink based on a response received from the network entity. As such, network cognizant uplink transmissions during inter radio access technology (IRAT) handovers may be achieved.

Abstract: In an aspect of the disclosure, a method of wireless communication is provided. The method may include starting a first timer for changing to a first network cell with a first radio access technology (RAT) and starting a second timer for changing to a second network cell with a second RAT. Further, the method may include changing to the first network cell when the first timer expires. The method may also include determining that the second network cell satisfies a cell change condition and continuing to run the second timer after the change to the first network cell in response to the second network cell satisfying the cell change condition. The method may further include changing to the second network cell after starting a third timer for a third network cell with the first RAT, a duration of the second timer being longer than a duration of the third timer.

Abstract: Aspects described herein relate to configuring a primary component carrier (PCC) and at least one secondary component carrier (SCC) for transmitting uplink communications to one or more nodes of a wireless network using carrier aggregation (CA) in a first subscription of the UE, and transmitting, to at least one of the one or more nodes, a manipulated power headroom report for the at least one SCC based on a migration from an idle state to an active state in a second subscription of the UE.
