System and Method for Two-way Relaying with Beamforming

A method comprising:

• transmitting, by a relay, transmission parameters to a subset of communications devices coupled to the relay;
• receiving, by the relay, precoding vectors from communications devices in the subset of communications devices;
• determining, by the relay, a precoding matrix from the precoding vectors;
• providing, by the relay, the precoding matrix to communications devices coupled to the relay;
• storing, by the relay, a portion of transmissions from the subset of communications devices;
• and
• transmitting, by the relay, a transmission comprising a combination of at least a subset of the stored portion of the transmissions, wherein the transmission is precoded with the precoding matrix.
