In this paper, an effective LTE-V2V (long-term-evolution vehicle-to-vehicle) communication system is studied, where the uplink channel of the cellular user equipment (CUE) is reused by the multiple V2V links. Considering the co-channel interference caused by channel reusing between CUE and V2V links, a pricing framework of interference management for V2V links and CUE is proposed. In the LTE-V2V communication networks, the base station (BS) protects the serving CUE by pricing the cross-tier interference caused by V2V links. A Stackelberg game is presented to model the interaction between the BS and V2V links. In order to ensure the communication quality of CUE, the total interference generated by V2V links has to be lower than the interference threshold. Specifically, the BS prices the tolerable interference to maximize its revenue. For the given prices, the V2V links competitively adapt their power allocation strategies to maximize the individual utility. Two pricing iterative algorithms, uniform pricing scheme and the non-uniform pricing scheme, are proposed to incorporate with the theory of noncooperative game, in order to analyze the competition between V2V links. In addition, the time-varying characteristics of vehicle communication are considered due to the high-speed mobility of the V2V users. The imperfect channel state information (CSI) fading model is constructed with the large-scale fading and small-scale fading jointly. Numerical simulation results validate the reliability and effectiveness of the proposed algorithms.

本文研究了有效的LTE-V2V（长期演进的车对车）通信系统，其中，蜂窝用户设备（CUE）的上行链路信道被多个V2V链路复用。考虑到CUE和V2V链路之间的信道重用引起的同信道干扰，提出了V2V链路和CUE干扰管理的定价框架。在LTE-V2V通信网络中，基站（BS）通过对由V2V链路引起的跨层干扰定价来保护服务CUE。提出了Stackelberg游戏，以对BS和V2V链接之间的交互进行建模。为了确保CUE的通信质量，V2V链路产生的总干扰必须低于干扰阈值。具体地说，BS为可承受的干扰定价，以最大化其收入。对于给定的价格，V2V链路竞争性地调整其功率分配策略，以最大限度地提高单个公用事业。结合非合作博弈理论，提出了两种定价迭代算法：统一定价方案和非统一定价方案，以分析V2V链路之间的竞争。另外，由于V2V用户的高速移动性，考虑了车辆通信的时变特性。非理想信道状态信息（CSI）衰落模型是通过大规模衰落和小型衰落共同构建的。数值仿真结果验证了所提算法的可靠性和有效性。提出了统一定价方案和非统一定价方案，并结合非合作博弈理论，分析了V2V环节之间的竞争。另外，由于V2V用户的高速移动性，考虑了车辆通信的时变特性。非理想信道状态信息（CSI）衰落模型是通过大规模衰落和小型衰落共同构建的。数值仿真结果验证了所提算法的可靠性和有效性。提出了统一定价方案和非统一定价方案，并结合非合作博弈理论，分析了V2V环节之间的竞争。另外，由于V2V用户的高速移动性，考虑了车辆通信的时变特性。非理想信道状态信息（CSI）衰落模型是通过大规模衰落和小型衰落共同构建的。数值仿真结果验证了所提算法的可靠性和有效性。由于V2V用户的高速移动性，因此考虑了车辆通信的时变特性。非理想信道状态信息（CSI）衰落模型是通过大规模衰落和小型衰落共同构建的。数值仿真结果验证了所提算法的可靠性和有效性。由于V2V用户的高速移动性，因此考虑了车辆通信的时变特性。非理想信道状态信息（CSI）衰落模型是通过大规模衰落和小型衰落共同构建的。数值仿真结果验证了所提算法的可靠性和有效性。
