... for 67% of calls and 300 m for 95% of calls [5]. In turn, the minimum required accuracy for mobile- based position- ing solutions is 50 m for 67% of calls and 150 m for 95% of calls. Such accuracy ... UE. Thus, it may be advantageous first to force the UE to two-way SHO to per- form required RTT measurements. Then, release the added radio links and force the UE again to two-way SH...
