    Abstract: Techniques are provided to initiate signal transmissions for possible opportunistic reception by a mobile device, and/or to initiate opportunistic reception of signal transmissions for use in mobile device position location estimation. For example, a mobile device may use assistance data to identify a first signal to be transmitted over a first frequency band and a second signal to be transmitted over a second frequency band during a specific period of time. At least a portion of the second frequency band may be outside of the first frequency band. The mobile device subsequently attempts to opportunistically receive at least the first signal and the second signal via a receiver tuned to a reception frequency band that encompasses at least the first frequency band and the second frequency band. The mobile device may then process the opportunistically received signals to obtain measurements corresponding to at least the first and second signals.

    Abstract: A user equipment (UE) may receive Vehicle-to-Everything (V2X) information from a V2X entity, such as a vehicle, road side unit, or other UE carried by a pedestrian. The V2X information may be transmitted to a location server by the UE to obtain positioning assistance data. The location server may determine a coarse position of the UE using the V2X information and generate corresponding positioning assistance data including Positioning Reference Signal (PRS) information for neighbor base stations, which is transmitted to the UE. The UE may detect PRS signals from the neighbor base stations and perform position determination using the PRS signals. The V2X entity or a different V2X entity may also transmit PRS signals that are received by the UE and used along with the PRS signal from the neighbor base stations to perform position determination.

    Abstract: In one aspect, an apparatus and method for detecting conflicts between events is provided. In one example, a potential event from content of an active ongoing conversation associated with a user and one or more existing events associated with the user may be identified and compared to determine if a conflict exists between the potential event and at least one of the one or more existing events.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support selection of positioning reference signal (PRS) occasions. For example, a UE may identify a first pair of PRS occasions for monitoring a PRS at a first frequency and a second pair of PRS occasions for monitoring a PRS at a second frequency and occurring after the first pair of PRS occasions. The UE may measure a first PRS of the first pair of PRS occasions at the first frequency, and then measure a first PRS of the second pair of PRS occasions at the second frequency. The UE may then measure a second PRS of the first pair of PRS occasions at the first frequency after measuring the first PRS of the second pair of PRS occasions at the second frequency.
