Systems and methods for positioning mobile devices in a fifth generation wireless network
Abstract:
Techniques described herein are directed toward enabling location support for 5G New Radio (NR) wireless access by a user equipment (UE) by utilizing existing LTE location support. More specifically, LTE positioning protocol (LPP) messages may be communicated between a UE with NR wireless access and a location server (e.g. an LMF) in a 5G Core Network via an NG-RAN. The LPP messages may support RAT-independent and E-UTRA position methods by the UE such as A-GNSS or OTDOA for E-UTRA. The location server may obtain OTDOA related information from eNBs and ng-eNBs supporting LTE wireless access. A UE may request measurement gaps from a 5G base station (e.g. gNB) in order to obtain measurements for RAT-independent and E-UTRA position methods and may request an idle period in order to obtain LTE timing needed for E-UTRA measurements.
