Abstract

The present invention provides a positioning reference signal configuration, receiving method and device. The configuration method includes: based on the spatial quasi-co-location QCL relationship between the positioning reference signal PRS and a specific downlink signal, sending configuration information, the configuration information is used for Determine resources occupied by the PRS and the specific downlink signal. In the embodiment of the present invention, due to the configuration information sent by the network device for determining the resource occupied by the PRS and the specific downlink signal, the terminal device can clarify whether the PRS and the specific downlink signal have multiplexed downlink time domain resources, so as to correctly receive The PRS can further realize the positioning of the terminal device according to the received PRS, thereby improving the effectiveness of communication.

Description

Technical field [0001] The present invention relates to the field of communication technology, and more specifically to a positioning reference signal configuration and receiving method and equipment. Background technique [0002] In the Long Term Evolution (LTE) system, the positioning reference signal (Positioning Reference Signal, PRS) can only be transmitted in the resource block in the downlink subframe configured for the transmission of the positioning reference signal, and the PRS cannot be mapped to the allocation On the Resource Element (RE) of the Physical broadcast channel (PBCH), Primary Synchronization Signal (PSS) and Secondary Synchronization Signal (SSS), the PRS will not interact with any antenna. The cell-specific reference signals of the ports overlap. [0003] However, in the New Radio (NR) system, it is not clear how the network equipment configures the PRS, so that the terminal equipment (User Equipment, UE) cannot receive the PRS correctly, and thus cannot p...
