1. A channel state information processing method, the method comprising:
receiving, by a second communication node, configuration information sent by a first communication node, wherein the configuration information comprises: a target frequency band used for indicating channel state information;
determining, by the second communication node, a first target frequency band according to the configuration information and generating, by the second communication node, first channel state information corresponding to the first target frequency band according to the configuration information, wherein the first channel state information is precoding matrix information, and the first target frequency band is a dedicated frequency band allocated to the precoding matrix information;
determining, by the second communication node, a second target frequency band according to the configuration information and generating, by the second communication node, second channel state information corresponding to the second target frequency band according to the configuration information, wherein the second channel state information is channel quality indication information; and
feeding back, by the second communication node, the channel state information to the first communication node, wherein the channel state information comprises the first channel state information and the second channel state information.
