Abstract: Systems and methods are disclosed for providing base station localization. In one embodiment the system includes a network including a base station such as a 5G gNodeB (gNB); a Hetnet Gateway (HNG) in communication with the gNB, wherein the HNG includes a location server and wherein the HNG virtualizes and abstracts a collection of base stations and provides a complex network under its purview as a simple base station to a mobile packet core network; a plurality of Hyper Sync Network (HSN) nodes in communication with the gNB and the HNG, wherein the plurality of HSN nodes listen to User Equipments (UEs) to locate the UEs and to synchronize clocks on the gNB with the collection of HSN nodes or other gNBs; and an Evolved Serving Mobile Location Center (E-SMLC) server in communication with the HNG and for reporting the location of a UE.

Abstract: Systems, methods and computer software are disclosed for providing an energy efficient base station with synchronization. In one embodiment, a method is disclosed, comprising: performing traffic analysis to determine off-peak hours duration when traffic is light; updating downlink and uplink schedulers to transmit a minimum required signaling and control information; and wherein updating downlink and uplink scheduler for minimum required signaling and control information further comprises scheduling, in a downlink direction, at least one of transmitting only reference symbols over selected OFDM symbols, PDCCH on up to a first three OFDM symbols, PSS and SSS on a central six PRB s and PBCH.

Abstract: Systems, methods and computer software are disclosed for providing high resolution timing advance estimation based on Physical Random Access Channel (PRACH). An example method includes receiving a preamble signal r(n); performing signal conditioning on r(n); down sampling the signal and performing antialiasing filtering to provide a y(n) signal; correlating y(n) with a reference preamble with a reference preamble sequence c(n) to provide correlation output Ryc; using a peak value P of the correlation output Ryc to detect a preamble ID and a timing advance; constructing a sequence s(n) by segmenting r_centered(n) for length L around an index P*24; performing time domain interpolation of c(n) around index P to obtain a sequence c_interpolated(n); performing time domain interpolation between sequences s(n) and c_interpolated(n); detecting a peak position Q of the correlation; and deriving TA as P*24−L/2+q in terms of Ts.
