For two-way relaying systems and methods beamforming

The present invention provides a two-way relaying system and method for beamforming. A method for a relay station operation including estimating a relay station and coupled to a number of communication channels between the communication device of the relay station, storing data contained in the transmission, storage, data contained in the transmission, the precoding matrix comprises stored data transmission of a subset of precoding and precoding transmission off. Based on the estimated transmission made by the communication device in the subset of the communication device, and the precoding matrix based on the estimated communication channel.
