How to create a grid of squares and attribute a color to the squares like in a contour plot?

Hello,

I want to reproduce the plots from a paper called "Fundamentals for Energy-Efficient Massive MIMO" where the author creates a 8x16 grid and gives temperature values for the contours like you can see here. The only "required" plot is (a), but it should be easy to reproduce (b) once (a) is done.

The problem is where to start with this. Can someone please point me directions?

Here is the idea

clc,clear

t = linspace(0,360,5)+45;       % create angles
t = [t-2 t+2];                  % add shifted angles
t1 = sort(t);                   % sorting
[x,y] = pol2cart(t1*pi/180,1);  % convert to cartesian
x(x>0) = x(x>0) + 1;            % move right part to right
x(x<0) = x(x<0) - 1;            % move left part to left
    % create surface
X = [x/10; x];                              
Y = [y/10; y];
Z = [x*0+1; x*0];

contour3(X,Y,Z,0:0.2:1)
surface(X,Y,Z)
