Table 3 Computation of the threshold frontier for switching on/off one carrier assuming with two traffics

1:

Define λ _TH =∅.

2:

Compute the mean power required by the two configurations (one and two carriers) for all possible traffic rates (λ _0v ,λ _0d ), P _1Ca(λ _0v ,λ _0d ) and P _2Ca(λ _0v ,λ _0d ).

3:

For a given λ _0v let \(\lambda ^{m}_{0d}\) be the maximum data traffic rate that can be supported with one carrier fulfilling the maximum blocking probability constraint.

Let \(\lambda = (\lambda _{0v},\lambda ^{m}_{0d})\). If P _1Ca(λ)<P _2Ca(λ), then λ _TH ←λ _TH ∪λ.

Otherwise, λ _0d is the data traffic value for which P _1Ca(λ)=P _2Ca(λ).

Then, λ _TH ←λ _TH ∪(λ _0v ,λ _0d ). Repeat for all possible λ _0v .

4:

At a given time instant where the traffic loads are (λ _0v [m],λ _0d [m]), one of the carriers will be switched off if there exists a point in the threshold frontier, (λ _0v,T ,λ _0d,T )∈λ _TH , such that λ _0v,T ≥λ _0v [m] and λ _0d,T ≥λ _0d [m].
