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.

Techniques for reducing resource usage for dual subscription dual active wireless communications

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.

Method and apparatus for network cognizant uplink transmissions during IRAT handovers

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.
