Title:
REFERENCE SIGNAL TRANSMISSION METHOD, USER EQUIPMENT, NETWORK DEVICE, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/237426
Kind Code:
A1
Abstract:
The embodiments of the present disclosure relate to the technical field of wireless communications. Disclosed are a reference signal transmission method, a user equipment, a network device, and an electronic device. The reference signal transmission method comprises: receiving configuration information of a positioning purpose reference signal sent by a first network device; and then performing, according to the configuration information, a first number of instances of positioning purpose reference signal transmission with a second network device within one slot, wherein the first number of instances is an integer greater than 1. By means of the method of the embodiments of the present disclosure, a positioning purpose reference signal can be sent multiple times within one slot, such that micro-slot-based sending of a positioning purpose reference signal is realized, thereby improving the positioning accuracy, reducing the positioning delay and meeting the requirements of an NR system for a positioning technology.
