The first device receives common pilot signals and demodulation signals over the radio channel in transmissions from the second device. Then, the first device estimates the radio channel based on the common pilot signals and the demodulation pilot signals and determines the radio channel based on the common pilot signals and the demodulation pilot signals. A first device for estimating a radio channel between the first device and a second device in a telecommunications system is also described."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Channel estimation in a multi-antenna wireless communications system","description":"A method performed by a first device for estimating a radio channel between the first device and a second device in a telecommunications system is provided.
