This is pattern FKOQR 1-1-1-4. It is a 4-shape tessellation, though I have combined two of the shapes into one, twice. I shaded the design in three colors.
Color and arrange four patches to make two 4-patch blocks as shown below.
Alternate the two 4-patch blocks like a checkerboard to make the pattern.
