摘要翻译：
Maddah-Ali和Niesen提出的编码缓存方案考虑通过确定性无差错网络将给定内容库中的文件传递给用户，在该网络中，公共组播消息以固定速率发送给所有用户，与用户数量无关。为了将这种模式应用到无线网络中，确保公共组播速率不会随着用户数的增加而消失是很重要的。本文重点研究了一种针对所谓的组合网络的编码缓存的变体，其中多播消息进一步由最大距离可分(MDS)码编码，并从不同的边缘节点（如基站或接入点）同时发送经MDS编码的块。每个用户配备有多个天线，并且可以选择解码所需数目的EN传输，同时根据它们的强度将其他的作为噪声处理的零位。该系统让人想起所谓的演进多媒体广播多播服务(eMBMS)，其基本的底层传输机制是多点多播，其中每个用户可以独立地和单独地（以用户为中心的方式）决定解码哪个EN，而不需要任何用户与ENS的明确关联。研究了当用户和ENs在平面上按齐次泊松点过程分布、传播受瑞利衰落和距离相关路径损失影响时，该系统的性能。我们的分析允许关于MDS编码速率的系统优化。此外，我们还证明了所提出的系统是完全可扩展的，即它可以支持任意数量的用户，同时保持不消失的每个用户的交付率。

英文摘要：
  The coded caching scheme proposed by Maddah-Ali and Niesen considers the delivery of files in a given content library to users through a deterministic error-free network where a common multicast message is sent to all users at a fixed rate, independent of the number of users. In order to apply this paradigm to a wireless network, it is important to make sure that the common multicast rate does not vanish as the number of users increases. This paper focuses on a variant of coded caching successively proposed for the so-called combination network, where the multicast message is further encoded by a Maximum Distance Separable (MDS) code and the MDS-coded blocks are simultaneously transmitted from different Edge Nodes (ENs) (e.g., base stations or access points). Each user is equipped with multiple antennas and can select to decode a desired number of EN transmissions, while either nulling of treating as noise the others, depending on their strength. The system is reminiscent of the so-called evolved Multimedia Broadcast Multicast Service (eMBMS), in the sense that the fundamental underlying transmission mechanism is multipoint multicasting, where each user can independently and individually (in a user-centric manner) decide which EN to decode, without any explicit association of users to ENs. We study the performance of the proposed system when users and ENs are distributed according to homogeneous Poisson Point Processes in the plane and the propagation is affected by Rayleigh fading and distance dependent pathloss. Our analysis allows the system optimization with respect to the MDS coding rate. Also, we show that the proposed system is fully scalable, in the sense that it can support an arbitrarily large number of users, while maintaining a non-vanishing per-user delivery rate.
