METHOD AND DEVICE FOR RECEIVING PPDU THROUGH BROADBAND IN WIRELESS LAN SYSTEM - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18215651 Titled 'METHOD AND DEVICE FOR RECEIVING PPDU THROUGH BROADBAND IN WIRELESS LAN SYSTEM'
Simplified Explanation
This abstract describes a method and device for receiving a PPDU (Physical Protocol Data Unit) in a wireless LAN system. The receiving STA (Station) receives the PPDU from a transmitting STA through a broadband connection and decodes it. The PPDU consists of a legacy preamble and first and second signal fields. These fields are generated based on a first phase rotation value, which is obtained from a first preamble puncturing pattern of the broadband. The first preamble puncturing pattern involves puncturing the 40 MHz or 80 MHz band in the 320 MHz broadband. The specific first phase rotation value is [1 −1 −1 −1 1 −1 −1 −1 −1 1 1 1 −1 1 1 1].
Original Abstract Submitted
Presented are a method and a device for receiving a PPDU in a wireless LAN system. Particularly, a receiving STA receives a PPDU from a transmitting STA through a broadband, and decodes the PPDU. The PPDU includes a legacy preamble and first and second signal fields. The legacy preamble and the first and second signal fields are generated on the basis of a first phase rotation value. The first phase rotation value is acquired on the basis of a first preamble puncturing pattern of the broadband. The first preamble puncturing pattern includes the pattern in which 40 MHz or 80 MHz band is punctured in the broadband, when the broadband is a 320 MHz band. The first phase rotation value is [1 −1 −1 −1 1 −1 −1 −1 −1 1 1 1 −1 1 1 1].
