A user equipment (UE) may monitor a channel for wireless communication associated with a first radio access technology (RAT) during one or more of a first active duration or a first inactive duration. The UE may operate in a first power mode during the first inactive duration. The UE may monitor the channel for wireless communication associated with a second RAT during one or more of a second active duration or a second inactive duration. The UE may operate during the second inactive duration in one or more of the first power mode or a second power. The UE may operate according to the first mode or the second mode based on the monitoring of the channel associated with the first RAT and the second RAT.

Techniques for managing a radio transceiver chain for multiple radio access technologies

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may operate in a dual-connectivity (DC) configuration, and may measure signals from more than one radio access technology (RAT). The UE may receive a first signal power for a first RAT and a second signal power for a second RAT. The UE may determine a common gain state for the first RAT and the second RAT based on the first signal power and the second signal power. The UE may then apply the common gain state to a first receiver chain within the UE for the first RAT and to a second receiver chain within the UE for the second RAT, where the first receiver chain and the second receiver chain share at least one shared low noise amplifier (LNA).

Common automatic gain control across multiple radio access technologies

Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may be scheduled to perform a first measurement or paging activity associated with a target cell operating according to a first target cell configuration that is different from a serving cell operating according to a first serving cell configuration of the UE. In some cases, the UE may determine that the UE has performed a previous measurement or paging activity associated with the target cell while being served by the serving cell, the cells operating according to previous cell configurations. The UE may compare at least one of the first and previous target cell configurations or the first and previous serving cell configurations, and may perform the first measurement or paging activity using a script, where the script is either reused or rebuilt based on comparing the cell configurations.

Script reuse during inter-frequency or inter-radio access technology measurements and paging

A user equipment (UE) with multiple receive chains and one or more subscriber identity modules improves radio access technology (RAT) measurements when one or more of the subscriber identity modules are active and valid measurement gaps or consecutive idle time slots are unavailable for the radio access technology measurements. The UE communicates with a first receive (RX) chain for a first subscriber identity module (SIM). The UE also performs the radio access technology (RAT) measurement with a second receive (RX) chain while maintaining communications with the first receive chain.

Inter radio access technology measurement with multiple receivers

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.
