Abstract
Certain aspects relate to techniques for z-axis rotation estimation for compensating signaling transmitted between two or more nodes over a wireless channel where an antenna array of at least one of the nodes is misaligned about the z-axis relative to another node. For example, a transmitting node may transmit pilot signals defined by phase shifts to provide a receiving node with a basis for estimating the angle of rotation by which the antenna arrays are misaligned. The transmitting node may then take remedial action to address the misalignment based on the estimation.
