1. A method in a Wireless Local Area Network (WLAN) system, the method comprising:
receiving, by a receiving station (STA), an Aggregated-Physical Protocol Data Unit (A-PPDU) from a transmitting STA; and
decoding, by the receiving STA, the A-PPDU,
wherein the A-PPDU includes a first PPDU for a primary 80 MHz channel and a second PPDU for a secondary 80 MHz channel,
wherein the first PPDU includes a first Legacy-Signal (L-SIG), and a first Repeated Legacy-Signal (RL-SIG), a High Efficiency-Signal-A (HE-SIG-A), a HE-SIG-B and a first data,
wherein the second PPDU includes the first L-SIG, the first RL-SIG, the HE-SIG-A, the HE-SIG-B, a second L-SIG, a second RL-SIG, a Universal-Signal (U-SIG), an Extremely High Throughput-Signal (EHT-SIG) and a second data,
wherein the HE-SIG-A includes an indicator of the A-PPDU,
wherein the first PPDU is a PPDU supporting a HE WLAN system, and
wherein the second PPDU is a PPDU supporting an EHT WLAN system.
