Performing the CCA procedure includes: for first signals having the first BSS identifier or having one or more second BSS identifiers corresponding to other virtual APs implemented by the physical AP, comparing energy of the signals to a first threshold; and for first signals determined by the communication device to have one or more third BSS identifiers, wherein the one or more third BSS identifiers correspond to other physical APs, comparing energy of the signals to a second threshold lower than the first threshold."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for uplink orthogonal frequency division multiple access communication in a WLAN","description":"A communication device performs a clear channel assessment (CCA) procedure to determine whether the communication device can transmit in a shared wireless communication medium, wherein the communicati","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10524290","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.
