Abstract: This specification describes a method comprising responding to a detection of a variation in at least one measured characteristic of a reference signal transmitted from an access point to a portable device by triggering participation by the portable device in vehicle-to-portable device communications. In some examples, the triggering of the participation in the vehicle-to-portable device communications in response to the detection of the variation in the at least one measured characteristic of the reference signal may be performed only if it has been determined that a location of the portable device satisfies a predetermined condition.

Abstract: This specification describes a method comprising detecting presence of a portable device in a vicinity of a first vehicle based on an identifier of the portable device which is detected at first user equipment, UE, located at the first vehicle, and further comprising causing transmission, from the first UE to a second UE located at a second vehicle in the vicinity of the first vehicle, of the identifier of the portable device and measurement data relating to the portable device and collected at the first vehicle, the measurement data being for use at the second vehicle to determine the location of the portable device relative to the second vehicle.
