Massive MIMO has been identified as one of the promising disruptive air interface techniques to address the huge capacity requirement of 5G wireless communications. For practical deployment of such systems, the control message needs 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...
In massive MIMO systems, the control message needs to be broadcast to all users reliably in the cell using broadbeam with identical radiated power in all directions. In practice, rectangular array structure has been widely identified as a solution to deployment of massive MIMO systems. In this paper, we will show that there is no perfect broadbeam with rectangular array structure. Therefore, we develop...
