US Patent 12150105 Summary

• Title: Wireless communication method and wireless communication terminal in basic service set overlapping with another basic service set
• Assignee: Wilus Institute of Standards and Technology Inc
• Inventors: Geonjung KO, Juhyung Son, Woojin AHN, Jinsam Kwak
• Filing Date: 2023-04-11
• Issue Date: 2024-11-19 (Publication of US12150105B2 and application granted on this date)
• Abstract: The patent describes a wireless communication method and a wireless communication terminal operating in an environment where basic service sets (BSSs) overlap. It aims to provide high-efficiency and high-performance wireless communication, particularly in high-density terminal environments, addressing issues like interference and contention procedures. The disclosed methods involve managing Basic Service Set (BSS) colors, setting Network Allocation Vectors (NAVs), and utilizing Spatial Reuse (SR) operations to optimize channel access and power saving, especially during BSS color collisions. The system uses a processor to transmit BSS colors and handle received Physical Layer Convergence Protocol (PLCP) Protocol Data Units (PPDUs) to determine appropriate channel access based on whether the PPDU originates from the same BSS (Intra-BSS) or another BSS (Inter-BSS).

Plain-Language Overview of Independent Claims:

• Independent Claim 1: This claim describes a wireless communication terminal that can wirelessly communicate. It includes a transceiver and a processor. The processor is set up to send out a "BSS color" which identifies the BSS (Basic Service Set) the terminal belongs to when it communicates with other terminals. If the terminal doesn't receive the information signaling the BSS color, it will send a specific, pre-determined value as its BSS color, which might be 0.
• Independent Claim 7: This claim also describes a wireless communication terminal with a transceiver and a processor. The processor is configured to receive a PPDU (PLCP Protocol Data Unit) through the transceiver. Based on whether this received PPDU is from its own BSS (Intra-BSS PPDU) or another BSS (Inter-BSS PPDU), the terminal will decide how to access the communication channel. An Intra-BSS PPDU means it's from the same BSS, while an Inter-BSS PPDU means it's from a different BSS.
• Independent Claim 10: This claim is for a wireless communication terminal including a transceiver and a processor. The processor receives a PPDU (PLCP Processing Data Unit) via the transceiver. If the BSS color indicated in that PPDU is a pre-determined value (e.g., a reserved value or zero), the processor will not perform an operation based on that BSS color. This could mean it won't perform a Spatial Reuse (SR) operation for that PPDU.
