[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 over 20MHz, 40MHz and 80MHz distribution bandwidths has been proposed for next-generation Wi-Fi to boost the transmit power for transmissions in the 6GHz low-power indoor (LPI) channels. There may be some possible DRU operation modes and scenarios. For instance, DRU may be used in a punctured Ultra-High-Reliability (UHR) trigger-based (TB) orthogonal frequency-division multiple-access (OFDMA) transmission. Also, a hybrid mode with DRUs and regular resource units (RRUs) may be utilized in UHR uplink (UL) TB OFDMA transmission. Moreover, in a non-punctured 80MHz physical-layer (PHY) protocol data unit (PPDU) , distribution bandwidth with 20MHz + 20MHz + 40MHz or 40MHz + 20MHz + 20MHz may be allowed for DRU transmission, However, at the time of the present disclosure, details on how to enable transmission of DRUs on a distribution bandwidth of 60MHz on frequency subblocks of a wide-bandwidth PPDU have not yet been specified.

In the description below, details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the presented embodiments and implementations. Overview
[0022] Implementations in accordance with the present disclosure relate to various techniques, methods, schemes and / or solutions pertaining to transmission of 60MHz DRU on frequency subblocks of wider bandwidths 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.
[0023] 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. 10 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. 10.
[0024] 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 transmission of 60MHz DRU on frequency subblocks of wider bandwidths 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.
[0025] FIG. 2 illustrates an example scenario 200 under a proposed scheme in accordance with the present disclosure. Scenario 200 may pertain to a DRU with a 60MHz distribution bandwidth. In case that one of the four 20MHz subchannels of an 80MHz bandwidth is punctured from the 80MHz bandwidth, the subcarriers or tones of the DRU may be distributed over the remaining non-punctured 60MHz as a 60MHz DRU. Referring to part (A) of FIG. 2, one possible scenario of a 60MHz DRU is for the tones distributed over the lower (left) three continuous 20MHz subchannels (e.g., the lower 60MHz) with the highest (rightmost) 20MHz being unallocated (e.g., due to puncturing) . Part (B) of FIG. 2 shows other possible scenarios of a 60MHz DRU, in which the tones may be distributed over the upper (right) three continuous 20MHz subchannels, over the lowest (leftmost) 20MHz subchannel plus the two upper (right) continuous 20MHz subchannels, or over the two lower (left) continuous 20MHz subchannels plus the highest (rightmost) 20MHz subchannels.
[0026] FIG. 3 illustrates an example design 300 under a proposed scheme in accordance with the present disclosure. Design 300 may pertain to a DRU tone plan for a distribution bandwidth of 60MHz. More specifically, design 300 may pertain to a design of DRUs related to a 52-tone DRU (DRU52) , a 106-tone DRU (DRU160) and a 242-tone DRU (DRU242) in an 80MHz PPDU with a DRU distribution bandwidth of 60MHz. The table in FIG. 3 shows DRU indices and subcarrier (tone) ranges of twelve DRU52s, six DRU106s and three DRU242s, respectively.
[0027] Under a proposed scheme in accordance with the present disclosure, with respect to 60MHz DRUs on frequency subblocks of a wide-bandwidth PPDU, tones of a DRU of any size on a distribution bandwidth of 60MHz may be distributed onto a frequency subblock of 80MHz of a wider bandwidth such as 160MHz or 320MHz. Such a DRU may be generated according to the mathematical expression below: kDRU_j = kDRU_i+ Kshift (l)
[0028] In the expression, kDRU may denote DRU subcarrier indices from the DRU tone plan table of design 300, shown in FIG. 3, for a DRU distributed on a distribution bandwidth of 60MHz. Also, kDRU_j may denote DRU subcarrier indices of a PHY DRU index j on the lth frequency subblock, with l denoting a frequency subblock index of a frequency subblock of size of 80MHz on a 160MHz or 320MHz operating bandwidth. Moreover, kshift (l) may denote a constant shift value for the lth frequency subblock of frequency subblock size 80MHz, and kshift (l) = 500 or 499 + K1st for a frequency subblock of a size of 80MHz, with K1st denoting the starting tone index of a corresponding frequency subblock l of the frequency subblock of a size of 80MHz.
[0029] FIG. 4 illustrates an example scenario 400 under a proposed scheme in accordance with the present disclosure. Scenario 400 may pertain to two 80MHz frequency subblocks in a 160MHz bandwidth. Referring to FIG. 4, a first or lower (left) 80MHz frequency subblock may include two segments. The first segment may have a starting index of -1012 and an ending index of -515, and the second segment may have a starting index of -509 and an ending index of -12. Additionally, a second or higher (right) 80MHz frequency subblock may include two segments. The first segment may have a starting index of 12 and an ending index of 253, and the second segment may have a starting index of 509 and an ending index of 1012. Accordingly, tones of a 996-tone regular RU (RRU996) may be distributed over the lower (left) 80MHz frequency subblock, as RU1, with tone indices within [-1012: -515, -509: -12] . Similarly, tones of a RRU996 may be distributed over the higher (right) 80MHz frequency subblock, as RU2, with tone indices within [12: 509, 515: 1012] .
[0030] FIG. 5 illustrates an example scenario 500 under a proposed scheme in accordance with the present disclosure. Scenario 500 may pertain to distribution of tones of a DRU with a 60MHz distribution bandwidth on 80MHz frequency subblocks in a 160MHz bandwidth. Referring to FIG. 5, there may be two options. In a first option (Option-1) , an index -500 may be aligned to [-1012, 12]for the DRU with a 60MHz distribution bandwidth on a first and a second 80MHz frequency subblocks. In a second option (Opion-2) , an index -495 may be aligned to [-1012, 12] for the DRU with a 60MHz distribution bandwidth on the first and the second 80MHz frequency subblocks.
[0031] FIG. 6 illustrates an example scenario 600 under a proposed scheme in accordance with the present disclosure. Scenario 600 may pertain to four 80MHz frequency subblocks in a 320MHz bandwidth. Referring to FIG. 6, a first 80MHz frequency subblock may include two segments. The first segment may have a starting index of -2036 and an ending index of -1539, and the second segment may have a starting index of -1533 and an ending index of -1036. Additionally, a second 80MHz frequency subblock may include two segments. The first segment may have a starting index of -1012 and an ending index of -515, and the second segment may have a starting index of -509 and an ending index of -12. Moreover, a third 80MHz frequency subblock may include two segments. The first segment may have a starting index of 12 and an ending index of 509, and the second segment may have a starting index of 515 and an ending index of 1012. Furthermore, a fourth 80MHz frequency subblock may include two segments. The first segment may have a starting index of 1036 and an ending index of 1533, and the second segment may have a starting index of 1539 and an ending index of 2036. Accordingly, tones of a RRU996 may be distributed over the first 80MHz frequency subblock, as RU1, with tone indices within [-2036: -1539, -1533: -1036] . Similarly, tones of a RRU996 may be distributed over the second 80MHz frequency subblock, as RU2, with tone indices within [-1012: -515, -509: -12] . Moreover, tones of a RRU996 may be distributed over the third 80MHz frequency subblock, as RU3, with tone indices within [12: 509, 515: 1012] . Furthermore, tones of a RRU996 may be distributed over the fourth 80MHz frequency subblock, as RU4, with tone indices within [1036: 1533, 1539: 2036] .
[0032] FIG. 7 illustrates an example scenario 700 under a proposed scheme in accordance with the present disclosure. Scenario 700 may pertain to distribution of tones of a DRU with a 60MHz distribution bandwidth on 80MHz frequency subblocks in a 320MHz bandwidth. Referring to FIG. 7, there may be two options. In a first option (Option-1) , an index -500 may be aligned to [-2036, -1012, 12, 1036] for the DRU with a 60MHz distribution bandwidth on a first, a second, a third and a fourth 80MHz frequency subblocks. In a second option (Opion-2) , an index -495 may be aligned to [-2036, -1012, 12, 1036] for the DRU with a 60MHz distribution bandwidth on the first, the second, the third and the fourth 80MHz frequency subblocks.
[0033] FIG. 8 illustrates an example design 800 under a proposed scheme in accordance with the present disclosure. Design 800 may pertain to the constant shift value for a DRU with a 60MHz distribution bandwidth on frequency subblocks in a 160MHz or 320MHz bandwidth. Under the proposed scheme, tones of DRUs with a distribution bandwidth of 60MHz and distributed on frequency subblocks of a wide-bandwidth PPDU may be defined as DRUs on a PPDU with a 60MHz distribution bandwidth in a first option (Option-1) or a second option (Option-2) . In Option-1, for frequency subblocks in 160MHz, the constant shift values may be [-512, 512] (i.e., the constant shift value being -512 for the first 80MHz frequency subblock and 512 for the second 80MHz frequency subblock) ; and for frequency subblocks in 320MHz, the constant shift values may be [-1536, -512, 512, 1536] (e.g., the constant shift value being -1536 for the first 80MHz frequency subblock, -512 for the second 80MHz frequency subblock, 512 for the third 80MHz frequency subblock, and 1536 for the first 80MHz frequency subblock) .

More specifically, process 1000 may represent an aspect of the proposed concepts and schemes pertaining to transmission of 60MHz DRU on frequency subblocks of wider bandwidths in wireless communications in accordance with the present disclosure. Process 1000 may include one or more operations, actions, or functions as illustrated by one or more of blocks. Although illustrated as discrete blocks, various blocks of process 1000 may be divided into additional blocks, combined into fewer blocks, or eliminated, depending on the desired implementation. Moreover, the blocks / sub-blocks of process 1000 may be executed in the order shown in FIG. 10 or, alternatively, in a different order. Furthermore, one or more of the blocks / sub-blocks of process 1000 may be executed repeatedly or iteratively. Process 1000 may be implemented by or in apparatus 910 and apparatus 920 as well as any variations thereof. Solely for illustrative purposes and without limiting the scope, process 1000 is described below in the context of apparatus 910 implemented in or as STA 110 functioning as a non-AP STA or an AP STA and apparatus 920 implemented in or as STA 120 functioning as an AP STA or a non-AP STA of a wireless network such as a WLAN in network environment 100 in accordance with one or more of IEEE 802.11 standards. Process 1000 may begin at block 1010.
[0042] At 1010, process 1000 may involve processor 912 of apparatus 910, as STA 110, performing, via transceiver 916, a wireless transmission (e.g., with apparatus 920 as STA 120) . The wireless transmission may be represented by 1012 or 1014.
[0043] At 1012, process 1000 may involve processor 912 generating and transmitting a DRU of a PPDU with tones of the DRU distributed on a 60MHz distribution bandwidth of an 80MHz frequency subblock of two or more frequency subblocks of a wider bandwidth.
[0044] At 1014, process 1000 may involve processor 912 receiving and processing the DRU.
[0045] In some implementations, the 80MHz frequency subblock may include four 20MHz subchannels. Moreover, one of the four 20MHz subchannels may be punctured such that the tones of the DRU are distributed over remaining three of the four 20MHz subchannels.
[0046] In some implementations, the tones of the DRU may be distributed over lower three continuous 20MHz subchannels while a highest 20MHz subchannel of the four 20MHz subchannels is punctured.

[0049] In some implementations, distribution of the tones of the DRU may be expressed mathematically as: kDRU_j = kDRU_i+ Kshift (l) ,
[0050] In such cases, kDRU may denote DRU subcarrier indices from a DRU tone plan table for the DRU distributed on the distribution bandwidth of 60MHz. Also, kDRU_j may denote DRU subcarrier indices of a PHY DRU index j on a lth frequency subblock. Additionally, l may denote a frequency subblock index of a frequency subblock of a size of 80MHz on the wider bandwidth of 160MHz or 320MHz. Moreover, kshift (l) may denote a constant shift value, with kshift (l) = 500 or 499 + K1st for the frequency subblock of the size of 80MHz. Furthermore, K1st may denote a starting tone index of a corresponding frequency subblock l of the frequency subblock of the size of 80MHz.

[0055] 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.
[0056] 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.
[0057] 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. ”
