The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: This disclosure provides methods, components, devices and systems for announcing opportunistic primary channel switching. Various aspects generally relate to a channel switch announcement (CSA) element that may announce an opportunistic primary (O-Primary) channel switch. Various aspects relate more specifically to an expanded channel switch mode field of a CSA element that may indicate whether a wireless station (STA) is permitted to transmit via the first O-Primary channel during the switch, whether a new operating class field is present in the CSA element, and an index associated with the switched O-Primary channel. In some aspects, the CSA element may be a separate information element, or an element defined within a non-primary channel access (NPCA) wrapper. The AP may transmit the CSA element via a beacon frame, a probe response frame, or a dedicated channel switch announcement frame.
