Title:
ENHANCED FINGERPRINT POSITIONING
Document Type and Number:
WIPO Patent Application WO/2022/126373
Kind Code:
A1
Abstract:
Embodiments of the present disclosure relate to fingerprint positioning in a wireless communication network. A method for establishing a positioning model comprises: obtaining, at a first device, a set of training data comprising historical measurements and historical regions, a historical measurement being associated with a second device, the second device being within one of the historical regions when the historical measurement is obtained; and training the positioning model by using the historical measurements as input of the positioning model and the historical regions as output of the positioning model to obtain parameter sets of Gaussian distributions of the positioning model, the Gaussian distributions indicating probabilities that a third device is positioned in the historical regions, and the parameter sets corresponding to respective non-light of sight levels of the historical regions. In this way, the positioning accuracy of fingerprint positioning method can be greatly improved.
