一般异构网络中的盲干扰对齐

Blind Interference Alignment in General Heterogeneous Networks

Vaia Kalokidou, Oliver Johnson, Robert Piechocki

摘要:

异构网络在未来移动通信网络的设计中具有关键作用,因为在宏小区周围采用小小区提高了网络的效率并降低了复杂性和功率需求。此外,对盲干扰对准(BIA)的研究已经表明,在某些网络架构中可以实现最佳自由度(DoF),而不需要发射机处的信道状态信息(CSI)。我们的贡献是一个广义模型的BIA在一个异构网络中的一个宏小区与K个用户和K个毫微微蜂窝每个用户,通过使用克罗内克(张量)产品表示。我们介绍了一种解决方案,如何改变波束成形向量下的功率约束,以最大限度地提高网络的总速率,以及如何最佳的自由度可以实现超过K+1时隙。

英文摘要:

Heterogeneous networks have a key role in the design of future mobile communication networks, since the employment of small cells around a macrocell enhances the network's efficiency and decreases complexity and power demand. Moreover, research on Blind Interference Alignment (BIA) has shown that optimal Degrees of Freedom (DoF) can be achieved in certain network architectures, with no requirement of Channel State Information (CSI) at the transmitters. Our contribution is a generalised model of BIA in a heterogeneous network with one macrocell with K users and K femtocells each with one user, by using Kronecker (Tensor) Product representation. We introduce a solution on how to vary beamforming vectors under power constraints to maximize the sum rate of the network and how optimal DoF can be achieved over K+1 time slots.
