Abstract
A method and a device for transmitting/receiving a PPDU in a wireless LAN system are disclosed. The method, performed by a first STA, according to an embodiment of the present disclosure may comprise the steps of: generating a physical protocol data unit (PPDU) to be transmitted within a frequency bandwidth of 160 MHz; and transmitting the PPDU to a second STA.
Claims15
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 160 MHz frequency bandwidth;
- and
- transmitting the PPDU to a second STA,
- wherein a plurality of first type resource units (RUS) within the 160 MHz frequency bandwidth are composed of subcarriers excluding one or more DC subcarriers, one or more guard subcarriers, and/or one or more null subcarriers,
- wherein each of the plurality of first type RUs is composed of discontinuous subcarriers at a predetermined interval in a frequency domain, and
- wherein a location for one or more first type RUs of the PPDU is indicated by an RU allocation subfield in an ascending order of the plurality of first type RUs based on a lowest subcarrier of each of the plurality of first type RUs in a frequency domain.
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 160 MHz frequency bandwidth;
- and
- transmit the PPDU to a second STA,
- wherein a plurality of first type resource units (RUS) within the 160 MHz frequency bandwidth are composed of subcarriers excluding one or more DC subcarriers, one or more guard subcarriers, and/or one or more null subcarriers,
- wherein each of the plurality of first type RUs is composed of discontinuous subcarriers at a predetermined interval in a frequency domain, and
- wherein a location for one or more first type RUs of the PPDU is indicated by an RU allocation subfield in an ascending order of the plurality of first type RUs based on a lowest subcarrier of each of the plurality of first type RUs in a frequency domain.
(canceled)
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 160 MHz frequency bandwidth;
- and
- process the PPDU,
- wherein a plurality of first type resource units (RUs) within the 160 MHz frequency bandwidth are composed of subcarriers excluding one or more DC subcarriers, one or more guard subcarriers, and/or one or more null subcarriers,
- wherein each of the plurality of first type RUs is composed of discontinuous subcarriers at a predetermined interval in a frequency domain, and
- wherein a location for one or more first type RUs of the PPDU is indicated by an RU allocation subfield in an ascending order of the plurality of first type RUs based on a lowest subcarrier of each of the plurality of first type RUs in a frequency domain.
