Abstract: Systems and methods for providing timely location estimates when a user equipment initiates a call to an emergency number are disclosed. The system enables a user equipment to send the earliest available location that the user equipment can come up with, after detecting an emergency message (e.g., detecting a 911 digit string). This can be done by sending the current location of the user equipment via HTTPS protocol to a telecommunications service provider node (e.g., an end point in GMLC). In this manner, the system avoids a major overhaul of the existing 3GPP E911 location standard while allowing timely compliance of the NG911 mandate.

Abstract: In an aspect, a UE (e.g., PUE or VUE) performs one or more sidelink positioning measurements on a first sidelink positioning signal between PUE and a VUE. The UE transmits measurement data based on the one or more sidelink positioning measurements to a RSU. The RSU receives the measurement data and determines a positioning estimate for the PUE. The RSU transmits the positioning estimate to the PUE, at least one VUE, or a combination thereof.

Abstract: A responder user equipment (UE) in separate ranging sessions may determine whether there is a collision between the ranging signals assigned to broadcast in the separate ranging sessions. A collision in the ranging signals is detected when the ranging signals have the same frequencies and broadcast times, e.g., the broadcast time of one ranging signal is within a predetermined amount of time for the other ranging signal. When a collision in the ranging signals is detected, the responder UE sends a message to the initiator UE indicating the possibility of a collision. Available times for broadcasting the ranging signals may be determined, e.g., by the responder UE or the initiator UE. The initiator UE may initiate a new ranging session based on the available times for broadcasting the ranging signal or may proceed with the ranging session with the possibility that the responder UE will not participate.
