Abstract
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.
