1. A method performed by a user equipment (UE) for transmitting location information, the method comprising:
receiving SPS (Satellite Positioning System) signals;
determining whether the received SPS signals are reliable;
determining a location estimate to be transmitted to other UEs, wherein a source of information used to determine the location estimate is the SPS signals if the received SPS signals are determined to be reliable and the source of information used to determine the location estimate is non-SPS information if the received SPS signals are determined to be not reliable; and
transmitting to one or more UEs, a wireless message that includes the location estimate for the UE and an indication of the source of information used to generate the location estimate, wherein the indication of the source of information comprises a variable indicating whether the source of information is the SPS signals or the non-SPS information, and wherein the non-SPS information indicating a wireless signal-based source of information comprising at least one of cellular signals, local area network (LAN) signals, sidelink signals, time difference of arrival (TDOA) positioning, angle of arrival (AoA) positioning, received signal strength (RSS) positioning, or any combinations thereof.
