Embodiment Construction

[0129] The present invention will be further described in detail with reference to the embodiments, and related technologies will be described first.

[0130] The following first describes the DL PRS configuration in the related art;

[0131] DL PRS is defined in R16 to support air interface positioning for UE. Since the new air interface (NR) has the multi-beam capability, the DL PRS defined in R16 can be sent by beam scanning by configuring multiple DL PRS resources (resources) in a resource configuration set. When the sending direction of the signal is directed to the terminal, the terminal can detect the arrival time of this direct line of sight path, which can effectively improve the accuracy of the terminal's estimation of the arrival time of the reference signal.

[0132] The configuration period supported by the DL PRS resource in R16 is 2μ{4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320, 640, 1280, 2560, 5120, 10240}, where μ=0,1, 2 and 3 represent that the sub-carrie...

Abstract

The invention discloses a positioning reference signal configuration method and device, a configuration triggering method and device, communication equipment and a storage medium. The method comprises the following steps: configuring on-demand DL PRS configuration information based on a location-based service request; the location service request positioning demand comprises at least one of the following: a time delay demand, a precision demand, recommended on-demand DL PRS configuration information, and a recommended on-demand DL PRS resource set; and sending the on-demand DL PRS configuration information to a target device.

Description

technical field [0001] The present invention relates to the field of wireless communication, and in particular, to a positioning reference signal (PRS, Positioning Reference Signal) configuration method, configuration triggering method, apparatus, communication device and storage medium. Background technique [0002] Communication protocol requirement 16 (R16, Release16) Downlink (DL, Downlink) PRS only supports periodic configuration, considering communication protocol requirement 17 (R17, Release17) positioning will be enhanced for indoor factory scenarios to achieve higher accuracy and higher Low-latency positioning capability and only supporting periodic DL PRS configuration will significantly increase the configuration overhead on the network side. In order to improve positioning accuracy, finer beam transmission needs to be used to improve the detection signal-to-noise ratio and beam granularity. Then, the positioning server needs to configure more DL PRS resources to ...
