Method and apparatus for receiving PPDU on which BCC interleaving has been performed in Multi-RU in wireless LAN system

A receiving station (STA) in a wireless Local Area Network (LAN), the receiving STA comprising:

• a memory;
• a transceiver;
• and
• a processor operatively coupled to the memory and the transceiver,
• wherein the processor is configured to:
• receive a Physical Protocol Data Unit (PPDU) including a data field from a transmitting STA;
• and
• decode the data field,
• wherein the data field is received through a multiple-resource unit (Multi-RU) in which a first resource unit (RU) and a second RU are aggregated,
• wherein the data field is deinterleaved in a BCC deinterleaver block by entering in rows of the BCC deinterleaver block based on a first parameter and by reading out in columns of the BCC deinterleaver block based on a second parameter.

A method in a wireless Local Area Network (LAN), the method comprising:

• generating, by a transmitting station (STA), a Physical Protocol Data Unit (PPDU) including a data field;
• and
• transmitting, by the transmitting STA, the PPDU to a receiving STA,
• wherein the data field is transmitted through a multiple-resource unit (Multi-RU) in which a first resource unit (RU) and a second RU are aggregated,
• wherein the data field is interleaved in a BCC interleaver block by entering in rows of the BCC interleaver block based on a first parameter and by reading out in columns of the BCC interleaver block based on a second parameter.
