Abstract

See full text

Methods, systems, and devices for wireless communications are described. A device may receive a directional positioning reference signal over one or more beams from another device. The device may transmit a broadcast positioning reference signal in response to receipt of the directional positioning reference signal. The device may receive, from the other device, a report including timing and directionality associated with transmission of the directional positioning reference signal. The report may also include timing and directionality associated with receipt of the broadcast positioning reference signal at the other device. Responsive to receipt of the report, the device may transmit beam specific measurement information associated with the one or more beams to the other device. The device may communicate with the other device using a beam of the one or more beams based at least on the report and the beam specific measurement information.
