Title:
METHOD AND DEVICE FOR APPLYING SEQUENCE AND PREAMBLE PUNCTURING TO A-PPDU IN WIRELESS LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/059055
Kind Code:
A1
Abstract:
The present specification (disclosure) proposes a method and device for applying a sequence and preamble puncturing to an A-PPDU in a wireless LAN system. Specifically, a reception STA receives an A-PPDU from a transmission STA. The reception STA decodes the A-PPDU. The A-PPDU includes a first PPDU for a primary 160 MHz channel and a second PPDU for a secondary 160 MHz channel. The reception STA is allocated to the secondary 160 MHz channel by SST. The first PPDU is transmitted on the basis of a first sequence for 160 MHz and a first preamble puncturing pattern for 160 MHz. The second PPDU is transmitted on the basis of a second sequence for 160 MHz and a second preamble puncturing pattern for 160 MHz.
