Problems solved by technology

The biggest feature of data transmission in this type of scenario is competitive transmission, that is, different terminal devices may choose the same resource for data transmission, resulting in resource conflicts between terminal devices, and reference signals based on contention transmission cannot be used for corresponding data transmission to terminal devices Accurate channel estimation and identification will eventually lead to the inability of network equipment to accurately receive the corresponding data of terminal equipment, resulting in reduced reliability of data transmission and affecting normal communication

Abstract

The present application provides a method and device for transmitting a reference signal. The method includes: a terminal device determines transmission power of a reference signal, wherein the transmission power of the reference signal corresponds to a generated characteristic value used to generate the reference signal; the terminal device transmits the reference signal according to the transmission power. The technical solution provided by the present application can improve the reliability of channel estimation and identification of terminal equipment based on contention data channels.

Description

technical field [0001] The present application relates to the field of communication technologies, and more specifically, to a method and device for transmitting a reference signal. Background technique [0002] With the evolution of wireless communication technology and the gradual penetration of mobile broadband Internet into different vertical industries, more and more traditional terminal devices need to access the mobile Internet to achieve interconnection and provide more convenient and differentiated services for their respective vertical industries, thus forming The Internet of Things (IoT) was born. [0003] IoT is an important application scenario of the next-generation mobile communication network 5G network. There are a large number of IoT devices in various shapes, and the data transmission mode is also different from traditional mobile devices such as mobile phones. In the current Internet of Things field, the uplink transmission of terminal devices adopts th...
