In the future, we plan to further analyse the performance of the macro-assisted energy savings schemes introduced in this paper by allowing parameters, such as the load of the macro cell dedicated to legacy UEs, the time before small cell disconnection, or the bandwidth difference between small cell and macro cell, to vary.
The first category, which is known as cross-tier interference, is the interference between small cells and macro cells.
A mathematical model to study the relationship between achievable energy savings by sleep mode BSs and the impact of delays on user QoS is provided in [30], but this analysis assumes independent operation of small cells and macro cells.
In terms of analysis level, it is distinguished between micro, meso and macro levels.
The signaling overhead between a small cell and the macro cell is 2α N L+K(β L+N L+γ(L+1)) bits.
However, the conduction of RBEBPC relies on the backhaul link ability between the small cell and the macro cell.
So in the extreme case, the backhaul link between the small cell and the macro cell should satisfy the data rate max{α N L,β L,N L+γ(L+1)} kbps.
AI blurs the lines between micro- and macro-level use-cases.

In sum, our decision is based on the distribution, i.e. on the gaps between the groups of small and large differences, especially the large gap between the TEs higher on the NFS, the observed migration of the flies between the slopes in "Evolution Canyon", which doesn't allow drift to be an explanation, and on all the differences between micro- and macro- studies.
