Title:
METHOD AND DEVICE FOR RECEIVING PPDU HAVING BEEN SUBJECTED TO LDPC TONE MAPPING IN BROADBAND TONE PLAN IN WIRELESS LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/006494
Kind Code:
A1
Abstract:
Proposed are a method and a device for receiving a PPDU having been subjected to LDPC tone mapping in a broadband tone plan in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA through broadband and decodes the PPDU. A data tone included in a data field is subjected to LDPC tone mapping on the basis of a first parameter. A tone plan for the 240 MHz band is 3x996 tone RUs, and a tone plan for the 320 MHz band is 4x996 tone RUs. The first parameter is 20.
