Abstract
According to a first aspect, it is provided a method for estimating angular spread of a wireless channel between a first node and a second node, wherein the first node is a radio network node and the second node is a user equipment, UE, or vice versa. The method is performed in a spread estimator. The method comprises the steps of: obtaining a wide-beam signal strength for a signal over the wireless channel using a selected wide-beam configuration of an antenna of the first node; obtaining a narrow-beam signal strength for a signal over the wireless channel using a selected narrow-beam configuration of the antenna of the first node; determining a difference between the wide-beam signal strength and the narrow-beam signal strength; and estimating angular spread of the wireless channel based on the difference.
