Information feedback method and apparatus, information receiving method and apparatus, device, and storage medium

An information feedback method, applied to a first node, comprising:

• receiving a report configuration sent by a second node;
• determining channel state information according to the report configuration, wherein the channel state information comprises a reference signal, and the reference signal satisfies a grouping criterion associated with the report configuration;
• and
• feeding the channel state information back to the second node through a report instance;
• wherein the channel state information further comprises at least one of grouping information, a reference signal receiving power (RSRP), or a signal to interference plus noise ratio (SINR);
• wherein in a case where the report configuration comprises a feedback using the RSRP and an antenna grouping criterion, a method for determining the channel state information comprises:
• creating N groups and setting a parameter i to 0;
• determining a best reference signal and best grouping information from an RSRP set;
• determining reference signals having top S RSRPs under the best grouping information;
• determining the reference signals having the top S RSRPs to be a reference signal set Ki for an ith group, and determining the best grouping information to be grouping information li for the ith group;
• in a case where the parameter i is less than N−1, removing an element in the RSRP set that is associated with the best grouping information to obtain an updated RSRP set;
• setting i to i+1, and returning to execution of determining the best reference signal and the best grouping information from the RSRP set;
• and
• in a case where the parameter i is equal to N−1, outputting the N groups.

A device comprising one or more processors and a memory configured to store programs that, upon execution by the one or more processors, cause the device to implement a method, comprising:

• receiving a report configuration sent by a second node;
• determining channel state information according to the report configuration, wherein the channel state information comprises a reference signal, and the reference signal satisfies a grouping criterion associated with the report configuration;
• and
• feeding the channel state information back to the second node through a report instance;
• wherein a method for determining the channel state information comprises:
• creating N groups and setting a parameter i to 0;
• determining, from a channel state set, at least one of following information under an ith group:
• a reference signal set Ki, grouping information li, or an antenna panel set Li;
• in a case where the parameter i is less than N−1, removing an element in the channel state set that is associated with the grouping information li or with the antenna panel set Li to obtain an updated channel state set;
• setting i to i+1, and returning to execution of determining the at least one of the following information under the ith group from the channel state set:
• the reference signal set Ki, the grouping information li, or the antenna panel set Li;
• and
• in a case where the parameter i is equal to N−1, outputting the N groups.
