AI Technical Summary

Problems solved by technology

When the terminal is moving at a medium-high speed, if the period for the terminal to feed back CSI is too long, the CSI feedback delay will be large, resulting in poor accuracy of feedback CSI
However, if the cycle of feedbacking CSI is too short, the CSI feedback signaling overhead will be relatively large.

Abstract

The invention discloses an information reporting method and device, an information receiving method and device, equipment and a storage medium, and relates to the field of mobile communication. The method comprises the following steps: a terminal sends channel state information to network equipment, the channel state information comprises a time domain parameter and / or a Doppler domain parameter, the terminal reports the channel state information comprising the time domain parameter and / or the Doppler domain parameter to the network equipment, the time domain parameter and / or the Doppler domain parameter can indicate the coherence time of a channel, and the time domain parameter and / or the Doppler domain parameter can indicate the coherence time of the channel. Therefore, the time domain correlation of the channel is determined based on the determined channel coherence time, and the CSI feedback accuracy is improved while the signaling overhead is reduced.

Description

technical field [0001] The present application relates to the field of mobile communications, and in particular, to a method, apparatus, device and storage medium for information reporting and information receiving. Background technique [0002] In the mobile communication technology, the terminal will feed back CSI (Channel State Information, channel state information) to the network device, so as to inform the network device of the channel measurement result of the terminal. When the terminal is moving at a medium and high speed, if the period for which the terminal feeds back CSI is too long, the CSI feedback delay is large, resulting in poor accuracy of the feedback CSI. However, if the period for feeding back the CSI is too short, the CSI feedback signaling overhead is relatively large. SUMMARY OF THE INVENTION [0003] The embodiments of the present application provide an information reporting and information receiving method, apparatus, device, and storage medium, ...
