Line-of-sight multiple-input multiple-output (los-mimo) communications using focusing elements

A first wireless communication device, comprising:

• a plurality of antenna elements;
• a transceiver coupled to the plurality of antenna elements, the transceiver configured to receive, from a second wireless communication device, a multiple-input-multiple-output (MIMO) signal, wherein the transceiver configured to receive the MIMO signal is configured to:
• receive, from the second wireless communication device via a first antenna element of the plurality of antenna elements, a first communication signal from a first direction, and
• receive, from the second wireless communication device via a second antenna element of the plurality of antenna elements, a second communication signal from a second direction different from the first direction;
• and
• a focusing element positioned in a receiving path of at least the first and second antenna elements, the focusing element configured to:
• direct the first communication signal in the first direction, and
• direct the second communication signal in the second direction.

A first wireless communication device, comprising:

• means for transmitting, to a second wireless communication device, a multiple-input-multiple-output (MIMO) signal, wherein the means for transmitting the MIMO signal comprises:
