Abstract
Certain aspects relate to techniques for estimating and compensating for antenna array rotation of a wireless node. For example, the antenna array of the wireless node may rotate about one or more of an x-axis, a y-axis, and a z-axis, which may misalign the antenna array relative to another antenna array of another wireless node, causing degradation of communications between the two nodes. In some examples, the wireless node may obtain, from a first antenna array of the other wireless node via a second antenna array of the first wireless node, a first pilot signal and a second pilot signal via a first beam. In some examples, the first wireless node may perform a first alignment compensation based on a phase difference between the first pilot signal and the second pilot signal.
