[0004] In wireless communications, such as Wi-Fi (or WiFi) in wireless local area network (WLAN) systems in accordance with the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standards, the use of DRUs is proposed for next-generation Wi-Fi to boost transmission power, for example, for 6GHz low-power indoor (LPI) channels. DRU tone plan may preserve the same hierarchical structure as that of regular RUs (RRUs) . For a Ultra-High-Reliability (UHR) trigger-based (TB) physical-layer protocol data unit (PPDU) transmission, the same signaling method of trigger frame for RRUs may be used for DRUs. However, at the time of the present disclosure, details of the RU Allocation subfield in the PPDU have yet to be defined. Therefore, there is a need for a solution of RU allocation subfield designs for DRUs in wireless communications.SUMMARY

[0023] Implementations in accordance with the present disclosure relate to various techniques, methods, schemes and / or solutions pertaining to RU allocation subfield designs for DRUs in wireless communications. According to the present disclosure, a number of possible solutions may be implemented separately or jointly. That is, although these possible solutions may be described below separately, two or more of these possible solutions may be implemented in one combination or another.
[0024] FIG. 1 illustrates an example network environment 100 in which various solutions and schemes in accordance with the present disclosure may be implemented. FIG. 2 ~ FIG. 11 illustrate examples of implementation of various proposed schemes in network environment 100 in accordance with the present disclosure. The following description of various proposed schemes is provided with reference to FIG. 1 ~ FIG. 11.
[0025] Referring to FIG. 1, network environment 100 may involve at least a station (STA) 110 communicating wirelessly with a STA 120. Either of STA 110 and STA 120 may function as an access point (AP) STA or, alternatively, a non-AP STA. In some cases, STA 110 and STA 120 may be associated with a basic service set (BSS) in accordance with one or more IEEE 802.11 standards (e.g., IEEE 802.11bn and future-developed standards) . Each of STA 110 and STA 120 may be configured to communicate with each other by utilizing the RU allocation subfield designs for DRUs in wireless communications in accordance with various proposed schemes described below. It is noteworthy that, while the various proposed schemes may be individually or separately described below, in actual implementations some or all of the proposed schemes may be utilized or otherwise implemented jointly. Of course, each of the proposed schemes may be utilized or otherwise implemented individually or separately.
[0026] FIG. 2 illustrates an example design 200 under a proposed scheme in accordance with the present disclosure. Design 200 may pertain to a User Info field of a UHR trigger frame for DRUs (e.g., according to IEEE 802.11bn or Wi-Fi 8 specification (s) for UHR) . Referring to FIG. 2, under the proposed scheme, the User Info field of a UHR trigger frame may be defined as shown when a DRU is transmitted.

As shown in FIG. 6, the one bit of the PS160 subfield and one of the 8 bits of the RU Allocation subfield (e.g., bit B0) may together indicate the 80MHz frequency subblock where the DRU is located.

Additional Notes
[0065] The herein-described subject matter sometimes illustrates different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely examples, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively "associated" such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as "associated with" each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being "operably connected" , or "operably coupled" , to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being "operably couplable" , to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and / or physically interacting components and / or wirelessly interactable and / or wirelessly interacting components and / or logically interacting and / or logically interactable components.
[0066] Further, with respect to the use of substantially any plural and / or singular terms herein, those having skill in the art can translate from the plural to the singular and / or from the singular to the plural as is appropriate to the context and / or application. The various singular / plural permutations may be expressly set forth herein for sake of clarity.
[0067] Moreover, it will be understood by those skilled in the art that, in general, terms used herein, and especially in the appended claims, e.g., bodies of the appended claims, are generally intended as “open” terms, e.g., the term “including” should be interpreted as “including but not limited to, ” the term “having” should be interpreted as “having at least, ” the term “includes” should be interpreted as “includes but is not limited to, ” etc. It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to implementations containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an, " e.g., “a” and / or “an” should be interpreted to mean “at least one” or “one or more; ” the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number, e.g., the bare recitation of "two recitations, " without other modifiers, means at least two recitations, or two or more recitations. Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc. ” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention, e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and / or A, B, and C together, etc. In those instances where a convention analogous to “at least one of A, B, or C, etc. ” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention, e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and / or A, B, and C together, etc. It will be further understood by those within the art that virtually any disjunctive word and / or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B. ”
