Abstract: Disclosed are techniques for wireless communication. In an aspect, a first wireless device transmits a request to participate in a coordination and detection procedure to determine whether a human is present in an environment of the first wireless device, receives an acknowledgment from at least a second wireless device, transmits a first set of at least two consecutive wireless signals to the second wireless device, receives a second set of at least two consecutive wireless signals from the second wireless device, determines whether the human is present in the environment based at least in part on a first time of flight (ToF) and a second ToF between the first wireless device and the second wireless device, and sets a transmit power of the first wireless device based on the determination of whether the human is present in the environment.

Abstract: Techniques are provided which may be implemented using various methods and/or apparatuses in a mobile device to crowd source mobile terrestrial transceiver identifiers associated with mobile terrestrial transports. In an embodiment, transceiver identifiers associated with mobile terrestrial transports may be identified and tracked through the detection and measurement of signals transmitted by mobile terrestrial transceivers received either by mobile devices located on the mobile terrestrial transport or through the detection and measurement of transient signals transmitted by passing mobile terrestrial transceivers received by stationary or near stationary mobile devices. The identity of detected mobile terrestrial transceivers and their locations and time observed may be uploaded to a server. The crowdsourced location and schedule information for the mobile terrestrial transports may be downloaded to mobile devices to provide transportation information such as arrival times, departure alerts, targeted stop alerts and other transport related functionality.

Abstract: Methods, systems, computer-readable media, and apparatuses for autonomous lane detection are presented. One example method includes the steps of receiving a signal from a first device; responsive to a comparison of a measured received frequency of the signal to a source frequency of the signal and to one or more thresholds, determining a distance to the first device; and determining a lane in which the vehicle is operating based on the distance and a lane map. Another example method further includes the steps of determining a location and a heading of the first vehicle; and outputting, to a crowdsourcing server, the location, the heading, and the distance to the first device.

Abstract: Methods, systems, computer-readable media, and apparatuses for automated lane assignment for vehicles are presented. One example method includes the steps of accessing vehicle information of at least one vehicle, the vehicle information including a priority level of a plurality of priority levels associated with each of the at least one vehicle; accessing lane information associated with a road, the lane information comprising information corresponding to at least two lanes of travel in a direction; and assigning at least one of the at least one vehicle to a lane of travel on the road based at least in part on the vehicle information and the lane information. Another example method further includes the step of accessing second vehicle information of a second vehicle, wherein assigning the first vehicle to the lane of travel is further based on the second vehicle information.
