Systems/methods of 5G advancements using a plurality of polarizations

A communications method comprising using a first device that is associated with a cellular system and is configured to communicate with a second device that is also associated with the cellular system while being subjected to a time-varying, dispersive, multipath fading environment;

• the first device comprising an antenna system that comprises a first polarization and a second polarization that differ from one another;
• wherein the first device is further configured to reduce an interference between the first polarization and the second polarization caused by said time-varying, dispersive, multipath fading environment while using the first polarization and the second polarization to increase a transmission throughput of information and/or a reception throughput of information;
• the communications method comprising:
• receiving a first signal on said first polarization comprising a first dependency on a first waveform and on a second waveform that have been transmitted by an antenna system of said second device;
• while co-frequency and concurrently in time with said receiving a first signal, receiving a second signal on said second polarization comprising a second dependency on the first waveform and on the second waveform that have been transmitted by the antenna system of said second device;
• performing a first operation and a second operation on the first signal and second signal, respectively, using a first receive channel coefficient, a second receive channel coefficient, a third receive channel coefficient and a fourth receive channel coefficient;
• and
• forming a first processed signal and a second processed signal;
• wherein the first processed signal comprises a reduced level of the second waveform compared to a level of the second waveform that is included in the first signal;
• wherein the second processed signal comprises a reduced level of the first waveform compared to a level of the first waveform that is included in the second signal;
• wherein said first receive channel coefficient relates to propagation of said first waveform from the antenna system of said another device to said first polarization;
• wherein the second receive channel coefficient relates to propagation of said first waveform from the antenna system of said another device to said second polarization;
• wherein the third receive channel coefficient relates to propagation of said second waveform from the antenna system of said another device to said first polarization;
• and
• wherein the fourth receive channel coefficient relates to propagation of said second waveform from the antenna system of said another device to said second polarization.
