Title:
INFORMATION TRANSMISSION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/104025
Kind Code:
A1
Abstract:
Disclosed are an information transmission method and device, for determining positioning reference signal resource configuration information and a positioning technical scheme by means of a negotiation process between a positioning server and other nodes, so as to avoid that neighboring base stations may send positioning reference signals on the same time and frequency resources, causing the positioning reference signals of neighboring base stations to interfere with each other, resulting in the degradation of downlink positioning measurement performance, and to enable each base station to optimize the configuration of the positioning reference signal according to the positioning performance requirements of a terminal, thereby improving the positioning performance. The information transmission method provided by the present application comprises: determining positioning reference signal resource configuration information and a positioning technical scheme by means of a negotiation process between a positioning server and other nodes; and notifying the other nodes of the positioning reference signal resource configuration information and the positioning technical scheme.
