Energy efficiency optimization transmitting power control method based on linear search and with service quality guarantee in D2D communication

An energy efficiency optimization transmitting power control method based on the linear search and with the service quality guarantee in D2D communication includes the following steps that firstly, through control over the transmitting power of a D2D communication user and a cellular network user, the purpose of D2D communication user energy efficiency optimization can be achieved on the premise that the service quality is guaranteed, and modeling is conducted for achieving the purpose; secondly, through a method that an auxiliary variable is introduced, an optimization problem P1 related to control over the transmitting power of the D2D communication user and the cellular network user is equivalently converted into an optimization problem P2 only related to the transmitting power of the D2D communication user; thirdly, through analysis, the optimization problem P2 is converted into an optimization problem P3 and the optimization problem P3 is solved through a linear search algorithm with the laying idea. The energy efficiency optimization transmitting power control method with the service quality guarantee in the D2D communication field can consider the basic circuit power consumption of a transmitter and optimize the user energy use efficiency.
