| Summary: | 碩士 === 國立中山大學 === 通訊工程研究所 === 106 === In this thesis, we propose a double cell embedded macro cell (DCEMC) networks
architecture. We consider the coverage of small cells may overlap in a macro cell. The
movement of user equipment (UE) may cause the signal switch from macro cell to a
small cell. It is also possible to switch form one of the small cells to the macro cell.
Because the UE’s movement changes the transmission distance and thus leads to
change the total transmission power of the macro cell and the small cells within the
macro cell. In this thesis, we establish a mathematical model with state transitions by
using probability. We divide different states based on the location of UE and its
connection. The state transition rate is obtained according to the velocity of the UE and
the channel usage of the small cell. We can calculate the probability of each state from
the mathematical model. We multiply each state probability by the square of the
transmission radius to obtain the total transmission power of the macro cell and the
small cells within the macro cell. Given the path loss factor, we can derive the
relationship of the cell’s coverage and the lowest power consumption.
