Method for sending channel state information and related device

A method for sending channel state information, wherein the method comprises:

• sending L reference signals, wherein L is a positive integer greater than or equal to 1;
• receiving channel state information, wherein the channel state information comprises resource indexes of M reference signals, K pieces of antenna panel state information, and M sets of channel quality information;
• and
• determining the M sets of channel quality information based on the K pieces of antenna panel state information, wherein:
• the M reference signals belong to the L reference signals;
• the K pieces of antenna panel state information indicate states of antenna panels;
• the K pieces of antenna panel state information are related to the M sets of channel quality information, wherein a piece of antenna panel state information in the K pieces of antenna panel state information indicates states of a plurality of antenna panels;
• the M sets of channel quality information are in a one-to-one correspondence with the resource indexes of the M reference signals;
• and
• M is a positive integer greater than or equal to 1 and less than or equal to L, and K is a positive integer greater than or equal to 1 and less than or equal to M.

A communications apparatus, comprises:

• one or more processors;
• and
• a memory, wherein the memory stores a computer program, and when executing the computer program stored in the memory, the one or more processors execute operations comprising:
• receiving L reference signals, wherein L is a positive integer greater than or equal to 1;
• and
• sending channel state information, wherein the channel state information comprises resource indexes of M reference signals, K pieces of antenna panel state information, and M sets of channel quality information, wherein:
• the M reference signals belong to the L reference signals;
• the K pieces of antenna panel state information indicate states of antenna panels;
• the K pieces of antenna panel state information are related to the M sets of channel quality information, wherein a piece of antenna panel state information in the K pieces of antenna panel state information indicates states of a plurality of antenna panels;
• the M sets of channel quality information are in a one-to-one correspondence with the resource indexes of the M reference signals;
• and
• M is a positive integer greater than or equal to 1 and less than or equal to L, and K is a positive integer greater than or equal to 1 and less than or equal to M.
