AI Technical Summary

Technical Problem

Network devices need to use different spatial parameter information indication mechanisms to indicate beam information for different uplink channels and uplink signals, resulting in high implementation complexity.

Method used

By sending the first indication information to configure the candidate spatial parameter information set, and using the same spatial parameter information indication mechanism to indicate different types of uplink channels and uplink signals, the indication information is carried using existing MAC CE or downlink control information, reducing signaling overhead and indication complexity.

Benefits of technology

It reduces the implementation complexity between network devices and terminal devices, improves indication efficiency, and enables rapid beam switching, especially in mobile scenarios, to avoid link interruption.

Abstract

This application provides a communication method, apparatus, system, and storage medium. The method includes: sending first indication information, which is used to configure a set of candidate spatial parameter information for a first uplink channel; and sending second indication information, which indicates at least one first spatial parameter information in the set of candidate spatial parameter information, wherein the at least one first spatial parameter information is used for transmission of a second uplink channel and / or an uplink signal, and the first uplink channel and the second uplink channel are of different types. The communication method, apparatus, system, and storage medium provided in this application, by indicating the spatial parameter information in the set of spatial parameters configured for the first uplink channel to the second uplink channel and / or uplink signal, allows the same spatial parameter information indication mechanism to be used to indicate spatial parameter information, reducing the implementation complexity between network devices and terminal devices.
