<p>Improvements to signaling procedures for use in physical random access channel (PRACH)-based proximity detection are disclosed. Signaling and signaling processes from a serving base station may trigger a more efficient and reliable transmission of PRACH from related user equipment (UE). At the dynamic power nodes (DPNs) monitoring for such PRACH-based proximity, features are disclosed which establish neighbor lists for more efficient management of detection and proximity activation.</p>
