Figures 1 to 14 The following description of various proposed approaches is provided.

[0032] Reference Figure 1 , the network environment 100 may include at least a station (STA) 110 and a STA 120 for wireless communication. Either of STA 110 and STA 120 may be a non-access point (non-AP) STA, or alternatively, either of STA 110 and STA 120 may be used as an access point (AP) STA. In some cases, STA 110 and STA 120 may be associated with a Basic Service Set (BSS) according to one or more IEEE 802.11 standards (e.g., IEEE 802.11be and future standards). Each of STA 110 and STA 120 may be configured to communicate with each other by utilizing a tone scheme design for a wide bandwidth RU for a next-generation WLAN according to various proposed schemes described below. That is, either or both of STA 110 and STA 120 may act as a "user" in the proposed scheme and the examples described below. It is worth noting that, although various proposed solutions are described separately or independently below, in actual implementation, some or all of the proposed solutions may be utilized or otherwise jointly implemented. Of course, each of the proposed solutions may be used or otherwise implemented separately or independently.
