Abstract
An apparatus and a method for beamforming in a wireless communication using a Base Station (BS) cooperative scheme are provided. The beamforming method includes exchanging channel status information with at least one cooperative BS which provides a BS cooperative service, generating a beamforming weight based on the channel status information, determining channel variation caused by a time delay in the channel status information exchange with the cooperative BS, updating the generated beamforming weight based on the channel variation, and precoding a transmit signal based on the updated beamforming weight.
