A BDS Based Positioning Framework with CoMP over LTE-A Networks

Jizhe Zhou and Yueying Zhang

Abstract: Recently, the Chinese BeiDou Navigation Satellite System (BDS) was officially announced to provide operational services around China and its neighborhood. It has been demonstrated to be very promising for precise navigation and positioning, which is importance ensure of information build develop for smart city. In this study, motivated by the proliferation of BDS devices, and the increasing maturity of wireless communication in long term evolution-advance (LTE-A) networks, we propose a BDS-based location estimate framework to improve the positioning accuracy via Coordinated Multi-Points (CoMP) technique. The evolved Node B (eNB) in LTE-A was defined to play a dual role, ordinary base station as well as reference station. In particular, according to different application scenarios, two modes of the framework are presented, i.e. network-centric mode and user-centric mode, respectively. Finally, to confirm the feasibility of the proposed framework, we also develop a pseudorange based positioning algorithm as an implementation. It also strengthens the extensibility, reconfiguration and portability of the system.
