The method is that: rate de-matching the front detection signal of each HS-SCCH part1 in the terminal HS-SCCH monitor set, obtaining the corresponding rate de-matched information; removing the user mask for the rate de-matched information of each HS-SCCH monitor channel; Viterbi decoding each rate de-matched information of which the user mask is removed, obtaining Viterbi-decoding 0 state accumulated metric of each HS-SCCH in HS-SCCH monitor set, and summing the absolute value of the soft information of each HS-SCCH monitor channel respectively, with the soft information being obtained by removing the user mask; according to the Viterbi 0 state accumulated metric of each HS-SCCH and the sum of absolute values of the corresponding soft information, obtaining determination variables of each HS-SCCH; selecting the maximum from the determination variables of HS-SCCH, comparing the maximum with the preset threshold, and determining whether the HS-SCCH of this user is detected."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Information detection method and apparatus for high speed downlink shared control channel","description":"An information detection method and apparatus for a High Speed Downlink Shared Control Channel (HS-SCCH) are provided by the present disclosure, implementing the detection of HS-SCCH part1 with low fa","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8526312","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.
