Abstract
Proposed are a method and a device for receiving an A-PPDU in a wireless LAN system. Specifically, a reception STA receives an A-PPDU from a transmission STA and decodes the A-PPDU. The A-PPDU includes a first PPDU for a primary 80 MHz channel and a second PPDU for a secondary 80 MHz channel. The first PPDU includes a first L-STF, a first L-LTF, a first L-SIG, a first RL-SIG, HE-SIG-A, HE-SIG-B, and first data. The second PPDU includes a pre-padding field, a second L-STF, a second L-LTF, a second L-SIG, a second RL-SIG, U- SIG, EHT-SIG, and second data. The pre-padding field consists of a sequence having no cross- correlation with the first L-STF and the first L-LTF.
