    Abstract: A dual-polarized multiple-input-multiple-output (MIMO) mobile device is provided that includes a first array of antennas and a second array of antennas. Based upon a blockage of at least one of the array of antennas being less than a blockage threshold, the mobile device operates in a default configuration in which a default polarization selection from the second array is used in combination with a fixed polarization selection from the first array to form a first MIMO layer signal and a second MIMO layer signal. Should the blockage exceed the blockage threshold and an optional performance threshold be satisfied, the mobile device may operate in a dynamic configuration in which a dynamic polarization selection from the second array is reversed as compared to the default polarization selection.
