[0038] Figure 1 An example network environment 100 is shown in which various solutions and schemes according to the present disclosure may be implemented. 1 shows an example of implementing various proposed solutions according to the present disclosure in a network environment 100. Provide descriptions of various proposed options.

[0039] refer to Figure 1, the network environment 100 may include at least a station (STA) 110 and a STA 120 for wireless communication. Any of STA 110 and STA 120 may be a non-access point (non-AP) STA, or any of STA 110 and STA 120 may function as an access point (AP) STA. In some cases, STA 110 and STA 120 may follow one or more IEEE 802.11 standards (e.g., IEEE 802.11be and future developed standards) to associate with a basic service set (BSS). According to various proposals described below, each of STA 110 and STA 120 may be configured to communicate with each other by utilizing the design of data and pilot subcarrier indexes for broadband RUs of next-generation WLANs. That is, any one or both of STA 110 and STA 120 may act as a "user" in the proposals and examples described below. It is worth noting that although various proposals may be described separately or separately below, in actual embodiments, some or all of all proposals may be used or implemented together. Of course, each proposal may be used or implemented separately or separately.

[0040] According to various proposed schemes of the present disclosure, the design of data and pilot subcarrier indices (or data and pilot tones) of RUs of different sizes transmitted on broadband (e.g., 240 MHz, 480 MHz, and 640 MHz) can be based on a subcarrier spacing (SCS) of 78.125 kHz. Such a design may help with backward compatibility because SCS=78.125 kHz has been defined in the IEEE 802.11be specification.

[0041] Figure 2 An example design 200 is shown according to a proposed scheme of the present disclosure. Design 200 involves data and pilot subcarrier indexing of RUs in a 240 MHz bandwidth (BW240). Figure 2 In design 200, data and pilot subcarrier indices may be generated based on existing 80MHz RU subcarrier indices (as defined in the IEEE 802.11be specification) with a constant offset relative to the center frequency. According to the proposed scheme, in order to symmetrically distribute the data and pilot subcarrier indices of multiple 80MHz RUs around the center frequency, the data and pilot subcarrier indices of the 80MHz RUs on both sides of the center frequency may be generated by a constant offset. For example, the data and pilot subcarrier indices of the 80MHz RU on the left side of the center frequency may be generated by an offset of -1024, and the data and pilot subcarrier indices of the 80MHz RU on the right side of the center frequency may be generated by an offset of +1024.

[0042] Figure 3An example design 300 according to a proposed scheme of the present disclosure is shown. Design 300 involves data and pilot subcarrier indexing of RUs in a 480 MHz bandwidth (BW480). According to the proposed scheme, there may be different options (Option-1, Option-2, and Option-3). Figure 3 In Option-1 shown in part (A), the data and pilot subcarrier indices of the RU in BW480 can be generated by generating a constant offset (compared to the center frequency) from the existing 80MHz RU subcarrier indices (as defined in the IEEE 802.11be specification). Figure 3 In Option-2 shown in Part (B), the data and pilot subcarrier indices of the RU in BW480 can be generated by generating a constant offset from the existing 160MHz RU subcarrier indices (as defined in the IEEE 802.11be specification). Figure 3 In Option-3 shown in Part (C), the data and pilot subcarrier indices of the RU in BW480 may be generated by generating a constant offset from the existing 240MHz RU subcarrier indices (as defined in the IEEE 802.11be specification).

[0043] In option -1, the data and pilot subcarrier indices of the 80MHz RU on both sides of the center frequency can be generated by constant offsets.

For example, the data and pilot subcarrier indices of the 160MHz RU on the left side of the center frequency can be generated by an offset of -2048, and the data and pilot subcarrier indices of the 160MHz RU on the right side of the center frequency can be generated by an offset of +2048.

[0045] In option-3, the data and pilot subcarrier indices of the 240MHz RU on both sides of the center frequency can be generated by a constant offset.

Figure 4 In Option-3 shown in part (C), the data and pilot subcarrier indices of the RU in BW640 may be generated by generating a constant offset from the existing 320MHz RU subcarrier indices (as defined in the IEEE 802.11be specification).

[0047] In option -1, the data and pilot subcarrier indices of the 80MHz RU on both sides of the center frequency can be generated by constant offsets. For example, the data and pilot subcarrier indices of the 80MHz RU on the left side of the center frequency can be generated by offsets of 3584, -2560, -1536, or -512, and the data and pilot subcarrier indices of the 80MHz RU on the right side of the center frequency can be generated by offsets of +512, +1536, +2560, or +3584.

[0048] In option-2, the data and pilot subcarrier indices of the 160MHz RU on both sides of the center frequency can be generated by constant offsets. For example, the data and pilot subcarrier indices of the 160MHz RU on the left side of the center frequency can be generated by offsets of -3072 or -1024, and the data and pilot subcarrier indices of the 160MHz RU on the right side of the center frequency can be generated by offsets of +1024 or +3072.

[0049] In option-3, the data and pilot subcarrier indices of the 320MHz RU on both sides of the center frequency can be generated by a constant offset. For example, the data and pilot subcarrier indices of the 320MHz RU on the left side of the center frequency can be generated by an offset of -2048, and the data and pilot subcarrier indices of the 320MHz RU on the right side of the center frequency can be generated by an offset of +2048.
