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.

Abstract: Methods, systems, and devices are described for storing and deleting received data packets over combined vehicular and wireless communications networks. In one example, an apparatus in a vehicular communication network may receive a data packet and may determine whether to store or delete the received data packet based on a ratio of distances between the data packet and its destination address as well as the data packet's source address and its destination address.

Abstract: Methods, systems, and devices are described for adapting access timing parameters when using DSRC spectrum. A multi-mode device may adapt at least one access timing parameter while operating within the DSRC spectrum. The at least one access timing parameter may be adapted to provide priority to transmissions of DSRC devices using the DSRC spectrum. The multi-mode device may increase a duration of a short inter-frame spacing (SIFS) to be at least equal to a duration of a SIFS used by a DSRC device.

Abstract: Methods, apparatuses, systems, and devices are described for wireless communication in an unlicensed spectrum. In one method, a clear-to-send (CTS) signal may be employed to manage or otherwise limit potential interference for communications in the unlicensed spectrum. For example, communications using long term evolution (LTE) may employ an unlicensed spectrum, particularly for small cell deployment. In such case, the LTE communications may be protected from interference due to communications by other networks, such as WiFi, using the unlicensed spectrum.
