We are bachelor Network Engineering Students and our graduation research project is about 5G mmWave in-door Localization for mobile devices.

The research is concerned to identify the in-door x,y,z location of a device using D2D Communication and to find the location by the RSSI using Localization techniques.

Is that possible to be done on ns3? If yes, what module should I use?

Regards, Thanks..

  • I have experience with D2D communication in NS-3, but I'm not aware of models for 5G. If you can case you can use WiFi (or other available protocol), please elaborate more your question and I can help – thenewjames Oct 17 '19 at 19:27
  • Yes it is possible. In mmWave module, you can find examples containing buildings which fulfills your first concern of indoor localization. As far as the location is concerned, you need a mobility model to extract the location however your question is unclear. When and where do you need the location of device? Because the method of getting the location at mac layer is different than getting it in the main() function after deployment. – a4arshad Nov 21 '19 at 02:04

Dedicated 5G indoor positioning measurements and procedures are focus area of 3GPP Release 16. Industrial scenarios with enhancements will be introduced with Release 17.

Location management function (LMF) sits in the center of 5G positioning architecture. The LMF receives measurements and assistance information from NG-RAN and the UE via AMF over the NLs interface to compute the position

New NR positioning protocol A (NRPPa) defined to convey information between NG-RAN and LMF over NG-C. LMF configures UE using the LTE positioning protocol (LPP) via AMF. The NG RAN configures the UE using radio resource control (RRC) protocol over LTE-Uu and NR-Uu.

NR Positioning reference signal (NR PRS) in the downlink and the sounding reference signal (SRS) for positioning in the uplink were added to NR specifications.

Since private 5G networks as 5G Edge will be deployed to big buildings, production zones same 5G positioning architecture will be applicable to 5G indoor positioning.
