Abstract: The location network deployment scheme and positioning technology deployment of 5G new radio (NR) in different scenarios are put forward. Positioning network deployment includes the overall architecture of core network and local deployment. 5G positioning technology deployment in different scenarios includes outdoor single station round trip time (RTT) + angle of arrival (AOA) scheme deployment, outdoor multi-RTT scheme deployment, indoor distributed environment up-link time difference of arrival (UL-TDOA) deployment, indoor distributed + integrated positioning Qcell + X wireless positioning. These technologies and solutions can bring great reference value for the positioning development of 5G era.
