Abstract
Disclosed are a method and device for transmission or reception on a channel with respect to a wide bandwidth in a wireless LAN system. The method performed by a first station (STA) in a wireless LAN system according to an embodiment of the present disclosure may include the steps of: generating a PPDU within a bandwidth belonging to a predefined frequency band; and transmitting the PPDU on a predetermined channel corresponding to a channel width smaller than the bandwidth.
Claims18
A method comprising:
- generating, by a first station (STA), a physical layer protocol data unit (PPDU) within a bandwidth located in a predefined frequency band;
- and
- transmitting, by the first STA, the PPDU on a predetermined channel corresponding to a channel width smaller than the bandwidth,
- wherein the PPDU includes one or more fields including allocation information for one or more resource units (RUs) on the predetermined channel,
- wherein the predetermined channel is configured by puncturing a channel having a specific size for the bandwidth, and
- wherein a location at which the channel having the specific size is punctured within the bandwidth is based on whether the bandwidth is located at a higher frequency or a lower frequency within the predefined frequency band.
3 more elements
An apparatus comprising:
- at least one transceiver;
- and
- at least one processor connected to the at least one transceiver,
- wherein the at least one processor is configured to:
- generate a physical layer protocol data unit (PPDU) within a bandwidth located in a predefined frequency band;
- and
- transmit, through the at least one transceiver, the PPDU on a predetermined channel corresponding to a channel width smaller than the bandwidth,
- wherein the PPDU includes one or more fields including allocation information for one or more resource units (RUs) on the predetermined channel,
- wherein the predetermined channel is configured by puncturing a channel having a specific size for the bandwidth, and
- wherein a location at which the channel having the specific size is punctured within the bandwidth is based on whether the bandwidth is located at a higher frequency or a lower frequency within the predefined frequency band.

An apparatus comprising:
- at least one transceiver;
- and
- at least one processor connected to the at least one transceiver,
- wherein the at least one processor is configured to:
- receive, through the at least one transceiver, a PPDU (physical layer protocol data unit) on a predetermined channel corresponding to a channel width smaller than a bandwidth located in a predefined frequency band;
- and
- process the PPDU based on allocation information for one or more resource units (RUS) on the predetermined channel included in one or more fields of the PPDU, wherein the predetermined channel is configured by puncturing a channel having a specific size for the bandwidth, and
- wherein a location at which the channel having the specific size is punctured within the bandwidth is based on whether the bandwidth is located at a higher frequency or a lower frequency within the predefined frequency band.
