1. A method, comprising:
obtaining a transmission opportunity (TXOP) in a wideband operating bandwidth comprising a primary channel and a plurality of non-primary channels;
initiating a frame exchange to reserve the TXOP for TXOP sharing;
performing a data transmission within the TXOP on one or more of the plurality of non-primary channels; and
sharing the primary channel with an overlapping basic service set (OBSS) after the frame exchange,
wherein the primary channel is shared by a basic service set (BSS) and the OBSS to initiate the frame exchange to reserve the TXOP for sharing, and
wherein the frame exchange sets or updates an intra-BSS timer of a 3rd-party device associated with the BSS but does not set or update an inter-BSS timer of a 3rd-party device associated with the OBSS.
