Problems solved by technology

At present, the same modulation and coding scheme (English: Modulation and Coding Scheme, abbreviation: MCS) is used for multiple repeated data transmissions, and the channel conditions will change with time, and the same MCS cannot be used for multiple repeated transmissions. To cope with the change of channel quality over time, the effect of repeated transmission on reliability improvement is weakened, that is, the reliability of data transmission is reduced

Abstract

The embodiment of the invention discloses a channel state indicating method, device and network equipment. Wherein, the method includes: the first network device acquires channel state information; the first network device generates channel state indication information, and the channel state indication information includes the absolute value of the channel state information, or the relative value of the channel state information Referring to the offset value of the channel state information; the first network device sends the channel state indication information to the second network device. Adopting the embodiment of the present invention helps to improve the reliability of data transmission.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a channel state indication method, device and network equipment. Background technique [0002] With the continuous development of communication technology, the requirements for services are getting higher and higher, such as high reliability and low latency. As a result, various technologies have emerged, such as the fifth generation mobile communication technology (English: The Fifth Generation Mobile Communication Technology, abbreviated: 5G) system compared with the fourth generation mobile communication technology (English: The Fourth Generation Mobile Communication Technology, abbreviated A major feature of the 4G) system is the addition of support for ultra-reliable and low-latency services (English: Ultra-reliable / low latency communication, abbreviation: URLLC). The URLLC technology can be applied in various fields, such as industrial control, industr...
