Abstract

The embodiment of the invention relates to the technical field of wireless communication, and discloses a reference signal transmission method, user equipment, network equipment and electronic equipment, and the reference signal transmission method comprises the steps: receiving the configuration information, transmitted by first network equipment, of a positioning purpose reference signal; and then, according to the configuration information, transmitting the positioning purpose reference signal for a first time with the second network equipment in one time slot, wherein the first time is aninteger greater than 1. According to the method provided by the embodiment of the invention, the positioning purpose reference signal can be sent for multiple times in one time slot, and the sending of the positioning purpose reference signal based on the micro time slot is realized, so that the positioning precision is improved, the positioning time delay is reduced, and the requirement of an NRsystem on a positioning technology is met.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of wireless communication technologies, and specifically, the present disclosure relates to a reference signal transmission method, user equipment, network equipment, and electronic equipment. Background technique [0002] In the NR (New Radio, new wireless technology) system, the downlink positioning reference signal PRS (Positioning Reference Signal, positioning reference signal) and the uplink positioning reference signal SRS (Sounding Reference Signal, sounding reference signal) are newly defined. . However, scenarios such as the Industrial Internet of Things need to be considered in the future. Industrial Internet of Things scenarios have higher requirements for positioning technology accuracy and delay, for example, the accuracy is less than 1m (meter), and the delay is less than 100ms (milliseconds) or even 10ms. However, the current design of PRS and SRS and related positioning technolo...
