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.
