Abstract

The application discloses a positioning reference signal transmission method and device. In this method, the base station maps the PRS sequence to the time-frequency resource used for sending the PRS according to the configuration information of the PRS; the base station sends the configuration information of the PRS to the terminal, and The mapped PRS is sent on the resource.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a positioning reference signal transmission method and device. Background technique [0002] Observed time difference of arrival (OTDOA) is a method introduced by 3GPP that utilizes the measured downlink reference signal time difference for positioning. In this method, a terminal (user equipment, UE, also called user equipment) measures reference signals from a serving cell and a neighboring cell to obtain a reference signal time difference measurement (reference signal time difference measurement, RSTD), and reports the RSTD to the network positioning server, The network location server determines the location of the terminal according to the RSTD and uses a multilateration algorithm or other algorithms. [0003] In principle, the terminal can use any downlink reference signal, for example, the primary synchronization signal (primary synchronization signa...
