The first device (30) is of a type which receives, on a downlink over a radio interface from a second device, precoded information (29). In an example mode the first device 28 generates a multi-part feedback signal (22) which is configured to affect content of a precoder matrix (40) utilized by the second device (28). On an uplink over the radio interface to the second device, at least two different parts of the multi-part feedback signal are transmitted with two respective different transmission granularities in time and/or frequency."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-granular feedback reporting and feedback processing for precoding in telecommunications","description":"A communications system comprises a second device (28) and a first device (30).
