A multiple-input multiple-output (MIMO) uplink subframe received from the subscriber station has a first subset of layers used for first codeword transmission and a second subset of layers used for second codeword transmission. Rank indication (RI) information is mapped onto both the first subset of layers and the second subset of layers. Channel quality information (CQI) is only mapped onto either the first subset of layers or the second subset of layers. If the first MCS value is different from the second MCS value, the CQI is mapped onto the subset of layers having a higher MCS value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for mapping uplink control information","description":"An uplink grant transmitted to a subscriber station indicates a first modulation and coding scheme (MCS) value for a first codeword transmission and a second MCS value for a second codeword transmissi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9680624","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.
