Channel information reporting method and apparatus

A communication apparatus, comprising:

• at least one processor configured with processor-executable instructions to perform operations comprising measuring a plurality of reference signals based on a plurality of reference signal resources;
• determining first delay information and first channel information based on the plurality of reference signals, wherein the first delay information comprises delay information corresponding to some or all reference signal resources in the plurality of reference signal resources, and the first channel information comprises channel information of each of the plurality of reference signal resources;
• performing delay difference compensation on the first channel information based on the first delay information, to determine second channel information;
• and
• determining a precoding matrix indicator (PMI) based on the second channel information, wherein the PMI indicates the second channel information;
• and
• reporting the first delay information and the PMI.

A non-transitory computer-readable storage medium storing computer instructions, that when executed by at least one processor, cause the at least one processor to perform operations comprising:

• measuring a plurality of reference signals based on a plurality of reference signal resources;
• determining first delay information and first channel information based on the plurality of reference signals, wherein the first delay information comprises delay information corresponding to some or all reference signal resources in the plurality of reference signal resources, and the first channel information comprises channel information of each of the plurality of reference signal resources;
• performing delay difference compensation on the first channel information based on the first delay information, to determine second channel information;
• and
• determining a precoding matrix indicator (PMI) based on the second channel information, wherein the PMI indicates the second channel information;
• and
• reporting the first delay information and the PMI.
