A device is configured to generate various orthogonal frequency division multiplexing (OFDM) and/or orthogonal frequency division multiple access (OFDMA) packets (e.g., frames, signals, etc.) that are based on any of a group of set of OFDM/A frame structures. Across the various OFDM/A frame structures, the ratio of pilot sub-carriers to data sub-carriers across resource units (RUs) of decreases as the total number of sub-carriers across the RUs increases. In addition, some of the OFDM/A frame structures include different total number of sub-carriers yet same number of pilot sub-carriers. The device is configured to perform adaptation among and between the various OFDM/A frame structures based on any one or more considerations."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data and pilot sub-carrier or tone design for OFDM/OFDMA in wireless communications","description":"A wireless communication device (alternatively, device) includes a communication interface and a processor, among other possible circuitries, components, elements, etc. to support communications with ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9634875","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.
