碩士 === 國立成功大學 === 電腦與通信工程研究所 === 102 === 4G LTE is widespread in the world, recent years. Except having a higher transmitting speed than 3rd-generation(3G), also include more efficient resource allocation. However, there always exists an issue of power consumption of mobility equipment. Accordingly, we will introduce a technology called “Device-to-Device communication” undelaying LTE, which connect each equipment without Base Station (BS) and only need to make a link between two devices. Due to this way, the purpose of reducing power consumption can be realized. In the case of how much power should transmitter transmit, we will introduce an algorithm named “Alternating Direction Method of Multiplier”. We put these two methods jointly to find out the optimal solution of minimum power consumption.
