==METHOD AND DEVICE FOR RECEIVING PPDU THROUGH BROADBAND IN WIRELESS LAN SYSTEM - A simplified explanation of the abstract==


This abstract first appeared for US patent application 17754727 titled 'METHOD AND DEVICE FOR RECEIVING PPDU THROUGH BROADBAND IN WIRELESS LAN SYSTEM

==Simplified Explanation==

The patent application describes a method and device for receiving a PPDU in a wireless LAN system, where a reception STA decodes the PPDU received from a transmission STA through a broadband, which can be a 320 MHz band or a 160+160 MHz band. The PPDU includes an STF signal generated based on a first STF sequence for the broadband, which is a sequence derived from a second STF sequence for an 80 MHz band in an 802.11ax wireless LAN system.

* Reception STA decodes PPDU from transmission STA in a wireless LAN system.

==Original Abstract Submitted==

A method and a device for receiving a PPDU in a wireless LAN system are presented. Specifically, a reception STA receives a PPDU from a transmission STA through a broadband and decodes the PPDU. The broadband is a 320 MHz band or a 160+160 MHz band. The PPDU includes an STF signal. The STF signal is generated on the basis of a first STF sequence for a broadband. The first STF sequence is a sequence of which a phase rotation is applied to a sequence in which a second STF sequence is repeated. The second STF sequence is an STF sequence for a 80 MHz band defined in an 802.11ax wireless LAN system. If the broadband is a 320 MHz band, the first SFT sequence is a sequence in which preset sequence M is repeated, and is defined to be the same as {M 1 −M 0 −M 1 −M 0 M 1 −M 0 −M 1 −M 0 −M −1 M 0 M −1 M 0 −M −1 M 0 M −1 M}*(1+j)/sqrt(2)).
