Channel bandwidth configuration method and device

An apparatus, comprising:

• at least one processor;
• and
• at least one memory that stores computer instructions, which when executed by the at least one processor, cause the apparatus to:
• receive an extremely high throughput (EHT) operation element, wherein the EHT operation element comprises a channel bandwidth field, a first channel center frequency field, and a second channel center frequency field, wherein the channel bandwidth field indicates a channel bandwidth of a basic service set (BSS), the first channel center frequency field and the second channel center frequency field indicate channel location information of the BSS, wherein the channel bandwidth field indicates a preset value equal to 4, the preset value equal to 4 indicates that the channel bandwidth of the BSS is 320 MHz, the first channel center frequency field indicates a center frequency of a primary 160 MHz channel in the 320 MHz channel bandwidth of the BSS, the second channel center frequency field indicates a center frequency of the 320 MHz channel bandwidth of the BSS, and a difference between a value of the first channel center frequency field and a value of the second channel center frequency field is equal to 16;
• and
• obtain bandwidth configuration information of the BSS based on the EHT operation element, wherein the bandwidth configuration information of the BSS comprises the channel bandwidth and the channel location information.
