US Patent 11356947: Wireless Communication Method and Wireless Communication Terminal, Which Use Discontinuous Channel

Current Status (as of 2026-04-26): Active, expires 2037-02-02.

A concise summary of US Patent 11356947 is provided below:

  • Title: Wireless communication method and wireless communication terminal, which use discontinuous channel
  • Assignee: Wilus Institute of Standards and Technology Inc. (Original Assignee: SK Telecom Co Ltd, Wilus Institute of Standards and Technology Inc.)
  • Inventors: Juhyung Son, Jinsam Kwak, Geonjung KO, Woojin AHN
  • Filing Date: 2020-05-07
  • Issue Date: 2022-06-07
  • Abstract: A wireless communication method and a wireless communication terminal, which use a non-contiguous channel, are disclosed. The wireless communication method of a wireless communication terminal includes receiving a wireless packet, obtaining non-contiguous channel allocation information of the received packet, and decoding the received packet based on the obtained non-contiguous channel allocation information.

Plain-Language Overview of Independent Claims:

  • Independent Claim 1: This claim describes a wireless communication method for a terminal. The method involves the terminal receiving a wireless packet, then identifying (obtaining) information about how non-contiguous channels are allocated within that packet. Finally, the terminal decodes the received packet by using this identified non-contiguous channel allocation information.

  • Independent Claim 13: This claim outlines a wireless communication terminal itself. The terminal includes a processor and a communication unit. The processor is configured to perform the actions described in Claim 1: receiving a wireless packet via the communication unit, obtaining non-contiguous channel allocation information from that packet, and then decoding the packet based on that allocation information.

  • Independent Claim 14: This claim details a wireless communication method executed by a base wireless communication terminal (e.g., an Access Point). The method involves the base terminal performing a Clear Channel Assessment (CCA) across multiple channels to prepare for transmitting a wideband packet. It then transmits the packet using at least one channel that is determined to be idle based on the CCA result. A key aspect is that if the packet is transmitted over non-contiguous channels, the base terminal signals this non-contiguous channel allocation information within a non-legacy preamble of the packet.

  • Independent Claim 19: This claim describes a base wireless communication terminal (e.g., an Access Point) that is capable of performing the method of Claim 14. It includes a processor and a communication unit. The processor performs the CCA of multiple channels for wideband packet transmission and transmits a packet through idle channels. When using non-contiguous channels, the processor signals the non-contiguous channel allocation information via a non-legacy preamble of the packet.


Note on CAFC 2026 Dockets: A search of CAFC 2026 dockets did not return specific litigation information for US11356947. The search results provided general information about the U.S. Court of Appeals for the Federal Circuit. However, the Google Patents information for US11356947 does indicate "Family has litigation" and points to a Darts-ip link for "Global patent litigation dataset". This suggests there is litigation activity related to the patent family, but direct CAFC dockets for 2026 specifically citing US11356947 were not found through this search.

Note on Abstract and Claims Retrieval: The provided plaintext document did not explicitly delineate "Abstract" and "Claims" sections with headings. The Abstract and the specific wording of the independent claims were retrieved from the Google Patents source (US11356947B2 - Wireless communication method and wireless communication terminal, which use discontinuous channel - Google Patents), which was the authoritative URL specified in the prompt.
