摘 要
随着移动通信技术的飞速发展，功率控制策略在移动通信系统中扮演着至关重要的角色。功率控制不仅关乎系统的容量、服务质量和用户体验，还直接影响着移动设备的电池寿命和能耗。因此，对移动通信中的功率控制策略进行深入研究，对于提升移动通信系统的整体性能具有重要意义。功率控制策略的核心目标是在满足用户通信需求的同时，尽可能降低发射功率，以减少对其他用户的干扰，提高频谱利用率，并延长移动设备的电池寿命。在实际应用中，功率控制策略的设计需要综合考虑多种因素，如无线信号的传播特性、信道条件、用户分布等。针对移动通信系统中的功率控制策略，研究者们提出了多种不同的方法。例如，基于距离的功率控制策略，它根据用户设备与基站之间的距离来调整发射功率，以补偿信号传输过程中的衰减。此外，还有基于信噪比的功率控制策略，它根据接收信号的信噪比来动态调整发射功率，以确保通信质量。这些策略各有优缺点，适用于不同的应用场景。

Abstract
With the rapid development of mobile communication technology, power control strategy plays a crucial role in mobile communication system. Power control is not only about the capacity of the system, quality of service and user experience, but also directly affects the battery life and energy consumption of mobile devices. Therefore, the in-depth study of power control strategy in mobile communication is of great significance to improve the overall performance of mobile communication system. The core goal of the power control strategy is to reduce the transmit power as much as possible while meeting the communication needs of users to reduce interference to other users, improve spectrum utilization, and extend the battery life of mobile devices. In practical applications, the design of power control strategy needs to consider many factors, such as wireless signal propagation characteristics, channel conditions, user distribution and so on. Aiming at the power control strategy in mobile communication system, researchers have proposed a variety of different methods. For example, a distance-based power control strategy adjusts the transmitted power according to the distance between the user device and the base station to compensate for attenuation during signal transmission. In addition, there is a power control strategy based on signal-to-noise ratio, which dynamically adjusts the transmitted power according to the signal-to-noise ratio of the received signal to ensure communication quality. These strategies have their own advantages and disadvantages and are applicable to different application scenarios.
