Method and apparatus for receiving ppdu on which bcc interleaving has been performed in multi-ru in wireless lan system

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

• a memory;
• a transceiver;
• and
• a processor operatively coupled to the memory and the transceiver,
• wherein the processor is configured to:
• generate a Physical Protocol Data Unit (PPDU) including a data field;
• and
• transmit the PPDU to a receiving STA,
• wherein the data field is transmitted with binary convolutional code (BCC) encoding on a multiple-resource unit (MRU),
• wherein BCC encoded bits of the data field are processed based on interleaver parameters including NCOL, NROW and NROT,
• wherein based on Dual Carrier Modulation (DCM) not used and a size of the MRU being 52+26 tone MRU, the NCOL is 18, the NROW is 4×NBPSCS, and the NROT is 18,
• wherein based on the DCM not used and the size of the MRU being 106+26 tone MRU, the NCOL is 21, the NROW is 6×NBPSCS, and the NROT is 31,
• wherein the NROW is a size of rows of a BCC interleaver block,
• wherein the NCOL is a size of columns of the BCC interleaver block,
• wherein the NBPSCS is a number of coded bits per subcarrier per spatial stream, and
• wherein the NROT is a parameter for frequency rotation.
