Abstract

The present application provides a method and related equipment for sending channel state information, the method comprising: receiving L reference signals, where L is a positive integer greater than or equal to 1; sending channel state information, the channel state information including the L reference signals The resource indexes of the M reference signals, K antenna panel status information and M groups of channel quality information, the K antenna panel status information indicates the status of the antenna panel, the K antenna panel status information and the M groups of channel quality information Correlation, the M groups of channel quality information are in one-to-one correspondence with the resource indexes of the M reference signals. Based on the above technical solution, the terminal device notifies the network device of the number and length of the sent channel quality information. In this way, the implementation complexity for the network device to acquire channel quality information can be reduced, and the burden on the network device can be reduced.

Description

technical field [0001] The present application relates to the technical field of communications, and more specifically, to a method and related equipment for sending channel state information. Background technique [0002] During the communication process between the terminal device and the network device, the network device will send a reference signal to the terminal device. The terminal device can measure the reference signal to obtain channel quality information and send the channel quality information to the network device. [0003] One terminal device may have multiple antenna panels (panels). An antenna panel can correspond to one or more beams. The multiple antenna panels in the terminal device may not all be active. In other words, the number of active antenna panels in the terminal device is not fixed. This results in that the length of the feedback information sent by the terminal device to the network device for feeding back the channel quality information is...
