Abstract

Methods, apparatuses, and computer readable media for basic service set (BSS) channel operation are disclosed. Apparatuses of a station (STA) are disclosed, where the apparatuses comprise processing circuitry configured to decode a first frame, the first frame comprising an extremely-high throughput (EHT) operation information field, the EHT operation information field comprising a channel width subfield and a channel center frequency segment, the channel width subfield indicating a basic service set (BSS) contiguous channel width, and the channel center frequency segment indicating a channel center frequency for the BSS channel width on which the BSS operates in 6 GHz. The processing circuitry further configured to encode for transmission a second frame for transmission on a primary channel within the BSS channel width.
