Various aspects of the disclosure relate to a request-response mechanism for sharing sensor information. For example, sensor devices and/or the like in objects (e.g., in vehicles, machines, fixed structures, etc.) may share information acquired by one or more sensors. The disclosure relates, in some aspects, to techniques for determining that sensor information may be beneficial for one or more regions (e.g., spaces, or areas) that may be occluded to one or more types of sensing, and based at least in part on such determination(s), pro-actively sharing, or requesting sharing, of applicable sensor information, e.g., between objects comprising a user equipment (UE) and one or more sensors.
