Abstract

Combating interference is one of the most outstanding challenges in wireless communication networks, especially for cellular networks with frequency reuse one. This issue becomes even more significant in heterogeneous networks where lower power nodes (such as pico-cell and/or femto-cell) are deployed within a macro-cell’s coverage. In this paper, we investigate interference coordination techniques in different scenarios. For homogeneous networks, we study single-cell multiuser MIMO for the purpose of intra-cell interference coordination and coordinated multi-point (CoMP) transmission for the purpose of inter-cell interference mitigation. For multi-user MIMO systems, we will discuss multi-user MIMO proportional-fair scheduling as well as multi-user precoding schemes. For CoMP transmission, we will focus on CoMP joint transmission and discuss the situations where CoMP could provide performance gains over single-cell operations. For heterogeneous networks, we investigate two specific inter-cell interference coordination techniques: time-domain solutions and power setting schemes. Furthermore, the potential extension of various CoMP schemes to heterogeneous networks will also be discussed.

抗干扰是无线通信网络中最突出的挑战之一，特别是对于频率复用的蜂窝网络。在异构网络中，低功率节点(如微蜂窝和/或飞蜂窝)部署在宏蜂窝的覆盖范围内，这个问题变得更加重要。本文研究了不同场景下的干扰协调技术。对于同构网络，我们研究了用于小区内干扰协调的单小区多用户MIMO和用于小区间干扰缓解的协调多点(CoMP)传输。对于多用户MIMO系统，我们将讨论多用户MIMO比例公平调度以及多用户预编码方案。对于CoMP传输，我们将重点讨论CoMP联合传输，并讨论在哪些情况下CoMP可以提供优于单单元操作的性能提升。对于异构网络，我们研究了两种特定的细胞间干扰协调技术:时域解决方案和功率设置方案。此外，还将讨论各种CoMP方案对异构网络的潜在扩展。
