Abstract: An inter-node interference reduction method, node and system, wherein the method includes: a first node obtaining link state information fed back by a terminal within the coverage range of the first node; the first node calculating joint information reflecting the interference of a second node with the terminal based on the link state information, and sending the joint information to the second node; the second node scheduling a terminal within its own coverage range based on the joint information, wherein the joint information includes a codebook limit cluster and further includes one or more of a power level limit cluster, a priority indication information cluster and an interference level indication information cluster, and a correspondence exists between constituent elements of any piece(s) of information within the joint information and constituent elements of other information except the any piece(s) of information within the joint information
