Title:
REFERENCE SIGNAL TRANSMISSION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/047797
Kind Code:
A1
Abstract:
Disclosed are a reference signal transmission method and apparatus, applicable to the field of automated driving, intelligent driving or short range communication, and capable of ensuring that all services have reference signal resources to implement channel phase tracking. The method comprises: a first node maps, on a first transmission resource, a reference signal and sending same. The first transmission resource is comprised in a second transmission resource for the first node to send data, and the second transmission resource comprises a first symbol and at least one subcarrier corresponding to the first symbol. The first transmission resource comprises the Mth subcarrier from the top and/or the Nth subcarrier from the bottom in the at least one subcarrier corresponding to the first symbol, and M and N are preset or protocol-specified or configured. The reference signal is used for determining phase information of a channel. The method improves the advanced driver assistance system (ADAS) capability of a terminal in automated driving or assisted driving, and can be applied to the Internet of vehicles, such as vehicle-to-everything (V2X), long-term evolution-vehicle (LTE-V), and vehicle-to-vehicle (V2V).
