Information reporting method, information receiving method, device, and storage medium

An information receiving method, applied to a second communication node, wherein the method comprises:

• transmitting first configuration information and second configuration information to a first communication node, so as to enable the first communication node to determine to-be-reported channel state information according to the first configuration information and the second configuration information;
• and
• receiving channel state information reported by the first communication node;
• wherein the channel state information comprises a precoding matrix indicator;
• a precoding matrix corresponding to the precoding matrix indicator is determined by a first group of vectors, or by a first group of vectors and a second group of vectors;
• wherein the first group of vectors comprises L vectors, the second group of vectors comprises Mv vectors;
• wherein L and Mv are both positive integers;
• a vector in the first group of vectors corresponds to a channel state information reference signal port;
• an element in a vector in the second group of vectors corresponds to a precoding matrix;
• wherein the second communication node indicates a value of Mv and a value of N by the second configuration information;
• wherein N candidate vectors are indicated by the value of N, the N candidate vectors are vectors with continuous index numbers;
• the Mv vectors are determined from the N candidate vectors;
• wherein determine the to-be-reported channel state information according to the first configuration information and the second configuration information, comprises:
• determining a reporting case of a vector in the second group of vectors by the first communication node, according to the value of Mv and the value of N;
• wherein determining the reporting case of a vector in the second group of vectors by the first communication node, according to the value of Mv and the value of N, comprises:
• corresponding to Mv being equal to N, not reporting, by the first communication node, a vector in the second group of vectors to the second communication node;
• and
• corresponding to Mv being not equal to N, reporting, by the first communication node, a vector in the second group of vectors to the second communication node.

A communication device, comprising a communication module, a memory, and one or more processors;

• wherein the communication module is configured to perform communication interaction between a first communication node and a second communication node;
• the memory is configured to store one or more programs;
• the one or more programs, upon being executed by the one or more processors, cause the one or more processors to implement;
• receiving first configuration information and second configuration information of a second communication node;
• receiving a channel state information reference signal transmitted by the second communication node, in accordance with the first configuration information;
• and
• reporting channel state information according to the channel state information reference signal and the second configuration information;
• wherein the channel state information comprises a precoding matrix indicator;
• a precoding matrix corresponding to the precoding matrix indicator is determined by a first group of vectors, or by a first group of vectors and a second group of vectors;
• wherein the first group of vectors comprises L vectors, the second group of vectors comprises Mv vectors;
• wherein L and Mv are both positive integers;
• a vector in the first group of vectors corresponds to a channel state information reference signal port;
• an element in a vector in the second group of vectors corresponds to a precoding matrix;
• wherein the second communication node indicates a value of Mv and a value of N by the second configuration information;
• wherein N candidate vectors are indicated by the value of N, the N candidate vectors are vectors with continuous index numbers;
• the Mv vectors are determined from the N candidate vectors;
• wherein reporting the channel state information according to the channel state information reference signal and the second configuration information, comprises:
• determining a reporting case of a vector in the second group of vectors by the first communication node, according to the value of Mv and the value of N;
• wherein determining the reporting case of a vector in the second group of vectors by the first communication node, according to the value of Mv and the value of N, comprises:
• corresponding to Mv being equal to N, not reporting, by the first communication node, a vector in the second group of vectors to the second communication node;
• and
• corresponding to Mv being not equal to N, reporting, by the first communication node, a vector in the second group of vectors to the second communication node.
