Title:
SHORT-DISTANCE HIGH-PRECISION POSITIONING METHOD AND POSITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/082163
Kind Code:
A1
Abstract:
A short-distance high-precision positioning method, comprising the following steps: a first mobile terminal acquiring a first position of an object (101); a second mobile terminal acquiring a second position of the object (102); the first mobile terminal obtaining, from a base station, a set of resources used for performing D2D communication (103); the second mobile terminal obtaining, from the base station, the set of resources used for performing D2D communication (104); a central mobile terminal obtaining, from the base station, the set of resources used for performing D2D communication (105); the central mobile terminal broadcasting a synchronization signal on a subset of the set of resources used for performing D2D communication (106); the first mobile terminal capturing the synchronization signal and the second mobile terminal capturing the synchronization signal (107); and in response to capturing the synchronization signal, the first mobile terminal obtaining a data channel of the central mobile terminal and a control channel of the central mobile terminal, and the second mobile terminal obtaining the data channel of the central mobile terminal and the control channel of the central mobile terminal (108). The method solves the problem of the positioning precision being significantly reduced once a wireless network is congested.
