摘要

大规模MIMO已被确定为解决5G无线通信对巨大容量需求的有前途的颠覆性空中接口技术之一。为了实际部署此类系统，需要使用宽带将控制消息可靠地广播给小区内的所有用户。一个完美的宽频波束应该在所有方向上具有相同的辐射功率，以覆盖小区中任何地方的用户。在本文中，我们将证明完美宽频不存在非平凡解。因此，我们开发了一种方法来产生宽波束，它可以允许辐射功率的微小波动。总的来说，这可以作为大规模MIMO系统实际部署的一个组成部分。

On the design of broadbeam for massive MIMO systems

Massive MIMO has been identified as one of the promising disruptive air interface techniques to address the huge capacity requirement demanded by 5G wireless communications. For practical deployment of such systems, the control messages need to be broadcast to all users reliably in the cell using broadbeam. A perfect broadbeam is expected to have the same radiated power in all directions to cover users in any place in a cell. In this paper, we will show that there is no non-trivial solution for perfect broadbeam. Therefore, we develop a method for generating broadbeam that can allow tiny fluctuations in radiated power. Overall, this can serve as an ingredient for practical deployment of the massive MIMO systems.
