Systems/methods of dual polarization transmission in cellular communications

A method of using a first device to transmit/receive information to/from a second device;

• the method comprising:
• transmitting to the second device a first signal on a first polarization;
• and
• transmitting to the second device a second signal on a second polarization;
• wherein said transmitting to the second device a second signal on a second polarization comprises transmitting co-frequency, and concurrently in time, with said transmitting to the second device a first signal on a first polarization;
• wherein the first signal comprises a plurality of first signals that are transmitted by a respective plurality of antennas over the first polarization;
• the plurality of first signals comprising a respective plurality of first amplitudes and phases so as to direct a total power being radiated substantially towards an antenna of the second device while reducing power being radiated toward locations other than that associated with the antenna of the second device;
• wherein said respective plurality of first amplitudes and phases are based on information, comprising an identity, received at the first device from the second device;
• and wherein the first signal further comprises a component of the second signal;
• and
• wherein the second signal comprises a plurality of second signals that are transmitted by a respective plurality of antennas over the second polarization;
• the plurality of second signals comprising a respective plurality of second amplitudes and phases so as to direct a total power being radiated substantially towards the antenna of the second device while reducing power being radiated toward locations other than that associated with the antenna of the second device;
• wherein said respective plurality of second amplitudes and phases are based on information, comprising an identity, received at the first device from the second device;
• and wherein the second signal further comprises a component of the first signal.
