METHOD AND APPARATUS FOR APPLYING PHASE ROTATION IN UNITS OF 10 MHZ BANDS IN WIRELESS LAN SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 17916751 titled 'METHOD AND APPARATUS FOR APPLYING PHASE ROTATION IN UNITS OF 10 MHZ BANDS IN WIRELESS LAN SYSTEM
Simplified Explanation
The patent application proposes a method and apparatus for receiving a PPDU (Physical Protocol Data Unit) in a wireless LAN system. The reception STA (Station) receives a PPDU from a transmission STA through a broadband and decodes it. The PPDU consists of a legacy preamble, and a first and a second signal field. These are generated based on a first phase rotation value.
- The first phase rotation value is [1, -1, -1, -1] when the first band is a 40 MHz band.
- Each element of the first phase rotation value is applied for each 10 MHz band in the first band.
Potential applications of this technology:
- Wireless LAN systems
- Broadband communication systems
Problems solved by this technology:
- Efficient reception of PPDU in wireless LAN systems
- Improved decoding of PPDU signals
Benefits of this technology:
- Enhanced performance and reliability of wireless LAN systems
- Improved data transmission and reception efficiency
Original Abstract Submitted
Proposed are a method and an apparatus for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA through a broadband and decodes the PPDU. The PPDU includes a legacy preamble, and a first and a second signal field. The legacy preamble and the first and the second signal field are generated on the basis of a first phase rotation value. When a first band is a 40 MHz band, the first phase rotation value is [1, −1, −1, −1]. Each element of the first phase rotation value is applied for each 10 MHz band in the first band.
