设备到设备（D2 D）通信是通过共享蜂窝网络的频谱资源来提高系统容量的优秀技术。组播业务被认为是未来移动的社交业务的有效传输方式。因此，基于D2 D技术的多播可以有效地提高频谱资源的利用率。如何应用D2 D技术支持组播业务是一个新的课题。为了提高系统性能，提出了一种基于认知无线电（CR）的D2 D多播通信资源分配方案（CR-DUM）。在认知蜂窝系统中，作为采用多播服务的次级用户的D2 D用户形成一个组，并且重用蜂窝资源来完成多播传输。所提出的方案包括两个步骤。首先，提出了一种旨在减少蜂窝网络对D2 D多播组中的接收机的干扰的信道分配规则。接下来，为了在干扰和噪声损害的条件下最大化总系统吞吐量，我们制定了蜂窝和D2 D多播通信的最优传输功率分配。在信道分配的基础上，以封闭形式从有限集合中搜索最优功率解，协调蜂窝和D2 D多播通信之间的干扰。仿真结果表明，该方法在保证服务质量（QoS）的同时，提高了系统吞吐量。
Device-to-device (D2D) communication is an excellent technology to improve the system capacity by sharing the spectrum resources of cellular networks. Multicast service is considered as an effective transmission mode for the future mobile social contact services. Therefore, multicast based on D2D technology can exactly improve the spectrum resource efficiency. How to apply D2D technology to support multicast service is a new issue. In this paper, a resource allocation scheme based on cognitive radio (CR) for D2D underlay multicast communication (CR-DUM) is proposed to improve system performance. In the cognitive cellular system, the D2D users as secondary users employing multicast service form a group and reuse the cellular resources to accomplish a multicast transmission. The proposed scheme includes two steps. First, a channel allocation rule aiming to reduce the interference from cellular networks to receivers in D2D multicast group is proposed. Next, to maximize the total system throughput under the condition of interference and noise impairment, we formulate an optimal transmission power allocation jointly for the cellular and D2D multicast communications. Based on the channel allocation, optimal power solution is in a closed form and achieved by searching from a finite set and the interference between cellular and D2D multicast communication is coordinated. The simulation results show that the proposed method can not only ensure the quality of services (QoS), but also improve the system throughput.
