Abstract
A method and apparatus of transmitting a PPDU in a wireless communication system is provided. The method includes selecting a subchannel among a plurality of subchannels, wherein a PLCP preamble and a PLCP header in each PPDU are independently generated in each of the plurality of subchannels, and transmitting a PPDU in the selected subchannel.

A method of transmitting a physical layer protocol data unit (PPDU) in a wireless communication system, the method performed by a wireless device and comprising:
- for a first data stream associated with a first PPDU to be transmitted via a first channel, including a first data block, a first header, and a first physical layer service data unit (PSDU) in the first data stream, wherein the first data block is followed by the first header which is followed by the first PSDU, and the first header indicates a modulation and coding scheme (MCS) of the first PSDU;
- for a second data stream associated with a second PPDU to be transmitted via a second channel, including a second data block, a second header, and a second PSDU in the second data stream, wherein the second data block is followed by the second header which is followed by the second PSDU, and the second header indicates an MCS of the second PSDU;
- performing a padding procedure on at least one of the first data stream and the second data stream so that a time duration during which the first data stream is transmitted and a time duration during which the second data stream is transmitted have an equal time duration;
- and
- transmitting the first data stream and the second data stream by using the first PPDU and the second PPDU, respectively.
A wireless device for transmitting a physical layer protocol data unit (PPDU) in a wireless communication system, the method performed by a wireless device, comprising:
- a processor configured to:
- for a first data stream associated with a first PPDU to be transmitted via a first channel, include a first data block, a first header, and a first physical layer service data unit (PSDU) in the first data stream, wherein the first data block is followed by the first header which is followed by the first PSDU, and the first header indicates a modulation and coding scheme (MCS) of the first PSDU,
- for a second data stream associated with a second PPDU to be transmitted via a second channel, include a second data block, a second header, and a second PSDU in the second data stream, wherein the second data block is followed by the second header which is followed by the second PSDU, and the second header indicates an MCS of the second PSDU, and
- perform a padding procedure on at least one of the first data stream and the second data stream so that a time duration during which the first data stream is transmitted and a time duration during which the second data stream is transmitted have an equal time duration;
- and
- a transmitter configured to transmit the first data stream and the second data stream by using the first PPDU and the second PPDU, respectively.
