Abstract
An apparatus and method for operating a Codebook Subset Pattern (CSP) of a Base Station (BS) in a Multiple Input Multiple Output (MIMO) system are provided. The method includes determining whether there is a CSP-updated BS among the BS and adjacent BSs, exchanging the updated CSP between cells if it is determined that there is a CSP-updated BS, and broadcasting the CSP of each cell acquired through the exchange thereby reducing an inter-cell interference in the MIMO system.
