    Abstract: Provided are a capability information feedback method and apparatus, and a channel state information feedback method and apparatus. The capability information feedback method comprises: transmitting, by a first communication node, capability information to a second communication node, where the capability information is used for indicating a capability of the first communication node; and receiving, by the first communication node, parameter signaling which is transmitted by the second communication node and corresponds to the capability of the first communication node. Through the method, the first communication node feeds the capability information supported by the first communication node back to the second communication node so that the second communication node can perform scheduling based on the capability of the first communication node, thereby reducing the system overhead and improving the system performance.
