Abstract
A source wireless access node serves User Equipment (UEs) over a Three-Dimensional (3D) Multiple Input Multiple Output (MIMO) antenna array and over a Two-Dimensional (2D) MIMO antenna array. The source wireless access node wirelessly exchanges user data with the UEs over the 3D MIMO antenna array. The source wireless access node detects a loss-of-synchronization. The source wireless access node detects an interference condition at neighbor wireless access nodes. When the interference condition at the neighbor wireless access nodes and the loss-of-synchronization at the source wireless access node occur simultaneously, the source wireless access node network disables the 3D MIMO antenna array and wirelessly exchanges additional user data with the UEs over the 2D MIMO antenna array. When the neighbor interference condition or the loss-of-synchronization terminate, the source wireless access node enables and uses the 3D MIMO antenna array.
