The profile is obtained by including, for any two neighboring frequencies of the selected subbands, an estimated CQI of a middle frequency between the two neighboring frequencies. After translating the CQIs of the two neighboring frequencies into corresponding linear CQI values, a linear estimated-CQI value for the middle frequency is determined by subtracting an offset from an average of said corresponding linear CQI values. The offset is determined according to a frequency separation between the two neighboring frequencies. Preferably, the offset is linearly proportional to the frequency separation. Interpolation, preferably linear interpolation, is used to obtain linear CQI values of other frequencies."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Channel-quality estimation for a wireless channel","description":"This invention provides a method for a first communication device, such as a base station, to estimate a channel-quality profile of a channel when a second communication device, e.g., a user equipment","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9722758","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
