Abstract:
A range between a first wireless device and a second wireless device is estimated using a first mechanism based on messages transmitted over a first communication channel. The first communication channel is associated with a first radio access technology capability of the wireless devices. One or more metrics indicative of an accuracy of the range estimates provided by the first mechanism are obtained. A second mechanism to estimate a range between the first wireless device and the second wireless device may be implemented in favor of the first mechanism when the metric fails to satisfy a criterion. The second mechanism is based on unicast messages transmitted over a second communication channel. The second communication channel is associated with a second radio access technology capability of the wireless devices and may be the same as, or different from, the first communication channel.

Claim (Index 30):
A first wireless device for range estimation, the first wireless device comprising:\n a processing system configured to:\n estimate a range between the first wireless device and one or more second wireless devices using a dedicated short-range communications (DSRC) mechanism based on timestamps associated with broadcast messages exchanged between the first wireless device and the one or more second wireless devices over a first communication channel; \n determine one or more accuracy metrics estimated by the DSRC mechanism, the one or more accuracy metrics being based on an estimation error, a packet loss probability, a level of congestion in a communications network supporting the first communication channel, a safety threshold, or a combination thereof; \n compare each of the one or more accuracy metrics to a corresponding threshold, the corresponding threshold including a maximum level of error, a maximum probability value, a maximum level of congestion, a minimum safety threshold, or a combination thereof, respectively; and \n switching to a second mechanism to estimate a range between the first wireless device and the one or more second wireless devices over a second communication channel in response to at least one of the one or more accuracy metrics failing to meet the corresponding threshold, wherein the switching comprises providing a control signal for transmission over the first communication channel, the control signal indicating that the estimation is to switch to the second mechanism that uses round trip time (RTT) ranging.
