1. A method for positioning co-located user equipment in a vehicle-to-everything (V2X) environment, comprising:
determining a first distance to a first wireless node;
sending an indication of a co-located state to a second wireless node based at least in part on the first distance to the first wireless node, wherein the indication of the co-located state is an information element comprising a flag indicating a true state;
receiving a first position estimate based at least in part on radio frequency signal exchanges between the first wireless node and the second wireless node;
determining a second distance to the first wireless node;
sending an indication of a non-co-located state to the second wireless node based at least in part on the second distance to the first wireless node, wherein the indication of the non-co-located state is an information element comprising a flag indicating a false state; and
determining a second position estimate based at least in part on radio frequency signal exchanges with the second wireless node.
