Abstract: Pulse signal transmission, such as radar pulses or the like are used in a high frequency mobile communication network as a means for determining or assisting in determining the likely presence of User Equipment (UE) and/or tracking UE in a predetermined area. As a result of determining the likely presence of UE and/or tracking UE, such information may be used to expedite either a handover or establish re-connection within the communication network. In this regard, more targeted beam sweeps or more frequent sweeps can be made in the direction where the UE has been determined to likely be present in order to hasten the establishment of the communication link between the targeted transmission point, such as a Base Station (BS) or the like, or reconnection to the existing transmission point.
