Pairing matrix A is in the example case of Figure 5-2 a 6x3 matrix with values χ n,m ∈ {0,1}. Value 0<br />
stands for link celln to MSm is not modelled and value 1 for link is modelled.<br />

A hando<strong>ver</strong> situation is characterized by a MS moving from the co<strong>ver</strong>age are of one BS to the<br />
co<strong>ver</strong>age area of another BS. Figure 5-3 illustrates this setup.<br />
