Figure 1 Fig.10 Provide descriptions of various proposed options.

[0029] 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 act 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 standards) to associate with a basic service set (BSS). According to various proposals described below, each STA 110 and STA 120 may be configured to communicate with each other by utilizing the design of multi-RU broadband PPDU in the next generation WLAN.

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.

[0030] According to various proposed schemes of the present disclosure, for broadbands greater than 80 MHz (e.g., 240 MHz, 480 MHz, and 640 MHz), a small-size MRU, for example, MRU (52+26) and MRU (106+26) may be used in each 80 MHz frequency sub-block of an orthogonal frequency division multiple access (OFDMA) 240 MHz, 480 MHz, or 640 MHz PPDU. In the proposed scheme, a small-size MRU combination defined in each 80 MHz frequency sub-block in the IEEE 802.11be specification may be reused in each 80 MHz frequency sub-block of a BW240 / BW480 / BW640 PPDU.

Similarly, in the proposed scheme, additional large size MRUs (MRU (996+484) and MRU (996+484+242)) can be used in each 160MHz frequency sub-block of the OFDMA 240MHz, 480MHz or 640MHz PPDU. In the proposed scheme, the large size MRU (996+484) and MRU (996+484+242) combinations defined in the 160MHz PPDU in the IEEE802.11be specification can be reused in each 160MHz frequency sub-block of the BW240 / BW480 / BW640 PPDU. In addition, other large-size MRUs, such as MRU (2x996+484), MRU (3x996), and MRU (3x996+484) can be used in each 320MHz frequency sub-block of OFDMA 480MHz PPDU or 640MHz PPDU. In the proposed scheme, the large-size MRU (2x996+484), MRU (3x996), and MRU (3x996+484) combinations defined in the 320MHz PPDU in the IEEE 802.11be specification can be reused in each 320MHz frequency sub-block of BW480 / BW640 PPDU.In addition, other MRUs may be used for OFDMA or non-OFDMA transmissions, which may include but are not limited to: MRU(2x996+484) and MRU(2x996) for BW240, MRU(5x996), MRU(4x996) and MRU(3x996) for BW480, and MRU(7x996), MRU(6x996), MRU(5x996) and MRU(4x996) for BW640.

[0067] Additional Notes

[0068] The subject matter described in this application sometimes shows different components contained in or connected to different other components.It is to be understood that the architecture depicted in this way is only an example, and many other architectures can actually be implemented, which realize the same function.In a conceptual sense, any component arrangement that realizes the same function is effectively "associated" so that the desired function is realized.Therefore, any two components combined here to realize a specific function can be regarded as "associated" with each other so that the desired function is realized, regardless of the architecture or intermediate components.Similarly, any two components so associated can also be regarded as "operably connected" or "operably coupled" to each other to realize the desired function, and any two components that can be so associated can also be regarded as "operably" coupled to each other to realize the desired function.The specific example of operable coupling includes but is not limited to physically pairable and / or physically interacting components and / or wirelessly interactive and / or wirelessly interactive components and / or logically interacting and / or logically interactive components.

[0069] In addition, with respect to any plural and / or singular number used in this application, a person skilled in the art can convert from the plural to the singular and / or from the singular to the plural according to the context and / or application. For the sake of clarity only, it is described here as singular / plural.

[0070] In addition, those with ordinary knowledge in the art will understand that, in general, the terms used in this application, especially in the appended claims, such as the bodies of the appended claims, are generally intended to be "open" terms, for example, the verb term "including" should be interpreted as "including but not limited to", the term "having" should be interpreted as "having at least", and the plural term "including" should be interpreted as "including but not limited to", and those with ordinary knowledge in the art will further understand that if it is intended to introduce a specific number into the recitation of the claims, such an intention will be explicitly stated in the claims, and in the absence of such a recitation, there is no such intention. For example, to aid understanding, the following appended claims may contain the introductory phrases "at least one" and "one or more" to introduce the recitation of the claims. However, the use of these phrases should not be interpreted as implying that a claim recitation introduced by the indefinite article "a" or "an" is limited to the implementation that any particular claim contains only one such recitation, even if the same claim includes the introductory phrases "one or more" or "at least one", and indefinite articles such as "a" or "an", for example, "a" and / or "an" should be interpreted as "at least" one "or" one or more; this interpretation also applies to the use of definite articles to introduce claim recitations. In addition, even if a specific number of introductory claim recitations is explicitly cited, a person of ordinary skill in the art will recognize that such recitation should be interpreted as meaning at least the cited number, for example, the simple recitation "two recitations", without other modifiers, means at least two recitations, or two or more recitations. Furthermore, in those cases where the phrases “at least one of A, B, and C, etc.” are used, such construction is generally intended to be in the sense that one of ordinary skill in the art would understand the convention, for example, “a system having at least one of A, B, and C” includes but is not limited to having only A alone, B alone, C alone, A and B together, A and C together, B and C together, and A, B, and C together, etc., and in those cases where the phrases “at least one of A, B, or C, etc.” are used, such construction is generally intended to be in the sense that one of ordinary skill in the art would understand the convention, for example, “a system having at least one of A, B, or C” would include but is not limited to having only A alone, B alone, C alone, A and B together, A and C together, B and C together, and A, B, and C together, etc. One of ordinary skill in the art would further understand that virtually any word and / or phrase presenting the character of two or more alternative terms, whether appearing in the specification, claims, or drawings, should be understood to be contemplated to include one of the terms, either of the terms, or both of the terms. For example, the phrase "A or B" will be understood to include the possibilities of "A" or "B" or "A and B."

[0071] It can be understood from the foregoing that the present application has described various implementations of the present disclosure for illustrative purposes, and various modifications can be made without departing from the scope and spirit of the present disclosure. Therefore, the various implementations disclosed in the present application are not intended to be limited to the true scope and spirit indicated by the appended claims.
