Abstract: A system stores first and second images generated by first and second cameras; applies a segmentation model to the first image to generate a first segmentation mask identifying object instances; applies the segmentation model to the second image to generate a second segmentation mask identifying the object instances; projects the first segmentation mask to a viewpoint of the second camera to generate a first projected segmentation mask; converts the first projected segmentation mask and the second segmentation mask to first and second semantic masks, respectively; and computes a first similarity value based on the first and second semantic masks. This may be repeated exchanging the first and second images to compute a second similarity value. The system determines a loss value based on the first similarity value and the second similarity value and trains the segmentation model based on the loss value.

Abstract: 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).

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: 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.

Abstract: 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.
