Abstract： Research on energy efficiency optimization of simultaneous wireless information and power transfer in heterogeneous small cellular networks. In order to maximize the energy efficiency of the downlink cellular system by jointly designing transmit beamforming vector and receive power splitting ratio under both small cellular users' communication quality and the collected energy, and the transmission power of the small cell base station constraints. The problem belongs to the nonconvex optimization problem, and the equivalent problem is transformed by the variable substitution, and then the subgradient iteration algorithm based on the Lagrange multiplier is used to solve the problem. The results of computer simulation show that the joint optimization algorithm is simple and effective.
