This paper uses the millimeter wave frequency band planned by the sixth-generation mobile communication system to conduct indoor communication quality research. It uses synchronous information and power transmission technology under high frequency conditions to simultaneously performs wireless charging and information transmission. In order to reduce the millimeter wave band attenuation of the channel path, this paper also uses beamforming technology, and deploys wireless nodes that only need wireless charging in the same environment at the same time. Considering both SWIPT nodes and WPT nodes, the algorithm is combined with the beamforming technology of array antennas to optimize the indoor communication quality and charging efficiency. This paper performs bit error rate and energy collection efficiency calculation to evaluate communication quality and charging efficiency respectively, and uses self-adaptive dynamic differential evolution method to set the error rate, SWIPT node and WPT node's basic requirements limit, so that it can consider the highest error rate and the minimum charging efficiency at the same time. The optimization for the three situations which the distance the between the transmitting antenna and individual SWIPT and the WPT node is closer、farther、similar when the two nodes are placed at any uniform indoor clear position. The results show that through the optimization of algorithms and multi-objective functions, both nodes can achieve the limited basic communication quality and the lowest energy collection efficiency. However, in order to further optimize the results, energy distribution mechanism in SWIPT node is added to the optimization and adjustment of the algorithm. Although there was only a slight improvement in both total and total distances when SWIPT was closer to TX than WPT was closer to TX, there was an 86.7% improvement in charging efficiency when SWIPT was closer to TX than WPT was closer to TX, and a 7.87% improvement when the total distance was longer. The overall system performance is improved, and the error rate can meet the conditions in all cases.
