POSITIONING MEASUREMENT METHOD AND DEVICE

WIPO Patent Application WO/2019/127246

A1

Provided are a positioning measurement method and device for ensuring the positioning measurement accuracy of a terminal covered by a base station configured with a network-based CRS reduction technology. The method involves: a positioning server sending a first request message to a base station, wherein the base station supports a network-based cell reference signal (CRS) reduction technology, and the first request message is used for requesting that the base station sends a CRS by occupying a system bandwidth in a measurement time domain; and the positioning server sending a notification message to a terminal, wherein the terminal supports positioning measurement by means of detecting the CRS on the system bandwidth, and the notification message is used for notifying the terminal to perform positioning measurement in the measurement time domain.
