The method is performed in the UE. The method comprises acquiring channel estimates for one antenna port of a network node. The method further comprises determining a variation of acquired channel estimates representing subframes associated with a common precoder, the subframes comprising resource blocks scheduled to the UE. The method further comprises estimating the channel spread by using a pre-determined mapping from the determined variation to a channel spread value. A user equipment and a computer program are also provided."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Channel spread estimation","description":"There is provided a method of estimating channel spread at a receiver of a user equipment, UE, for one antenna port of a network node.
