Title:
METHOD AND DEVICE FOR RECEIVING EHT SOUNDING NDP FRAME IN WIRELESS LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/101363
Kind Code:
A1
Abstract:
A method and a device for receiving an EHT sounding NDP frame in a wireless LAN system are presented. Particularly, a reception STA receives an EHT MU PPDU from a transmission STA, and decodes the EHT MU PPDU. The EHT MU PPDU includes a U-SIG field. The U-SIG field includes a UL/DL field, a PPDU type and compression mode field, and a punctured channel information field. The punctured channel information field includes information about a preamble puncturing pattern of a band in which the EHT MU PPDU is transmitted. If the value of the PPDU type and compression mode field is 3, the EHT MU PPDU is an EHT sounding NDP frame regardless of the value of the UL/DL field, and the preamble puncturing pattern is set as an OFDMA puncturing pattern.
