A method performed by a first station (STA) in a wireless local area network (WLAN) system, the method comprising:
- generating a PPDU (physical protocol data unit) to be transmitted within a 40 MHz frequency bandwidth;
- and
- transmitting the PPDU to a second STA,
- wherein each of a plurality of 26-tone distributed-tone resource units (DRUs) comprises distributed subcarriers with a specific gap in a frequency domain,
- wherein each 52-tone DRU of one or more 52-tone DRUs in the PPDU comprises two 26-tone DRUs of consecutive DRU indices, and
- wherein subcarrier indices of the two 26-tone DRUs in each 52-tone DRU are not contiguous.
A first station (STA) device in a wireless local area network (WLAN) system, the device comprising:
- at least one transceiver;
- and
- at least one processor connected to the at least one transceiver,
- wherein the at least one processor configured to:
- generate a PPDU (physical protocol data unit) to be transmitted within a 40 MHz frequency bandwidth;
- and
- transmit the PPDU to a second STA,
- wherein each of a plurality of 26-tone distributed-tone resource units (DRUs) comprises distributed subcarriers with a specific gap in a frequency domain,
- wherein each 52-tone DRU of one or more 52-tone DRUs in the PPDU comprises two 26-tone DRUs of consecutive DRU indices, and
- wherein subcarrier indices of the two 26-tone DRUs in each 52-tone DRU are not contiguous.
A second station (STA) device in a wireless local area network (WLAN) system, the device comprising:
- at least one transceiver;
- and
- at least one processor connected to the at least one transceiver,
- wherein the at least one processor configured to:
- receive a PPDU (physical protocol data unit) within a 40 MHz frequency bandwidth;
- and
- process the PPDU,
- wherein each of a plurality of 26-tone distributed-tone resource units (DRUs) comprises distributed subcarriers with a specific gap in a frequency domain,
- wherein each 52-tone DRU of one or more 52-tone DRUs in the PPDU comprises two 26-tone DRUs of consecutive DRU indices, and
- wherein subcarrier indices of the two 26-tone DRUs in each 52-tone DRU are not contiguous.
