BACKGROUND
Unless otherwise indicated herein, approaches described in this section are not prior art to the claims listed below and are not admitted as prior art by inclusion in this section.
In wireless communications such as Wi-Fi (or WiFi) and wireless local area network (WLAN) systems in accordance with one or more Institute of Electrical and Electronics Engineers (IEEE) 802.11be standards (e.g., IEEE 802.11ax/be), wider bandwidths, herein referring to bandwidths wider than 320 MHz such as 480 MHz and 640 MHz, have been proposed for system throughput improvement. Associated with these new/wider bandwidths, some new multi-resource unit (MRU) combinations are also considered. In a wider bandwidth, a user may transmit or may be assigned with resources across different power mode regions. To utilize the spectrum efficiently, scheduling different modulation and coding schemes (MCSs) or quadrature amplitude modulation (QAM) levels for different spectral resources may improve overall system throughput and link reliability. Moreover, system throughput and reliability may also be improved by assigning unequal modulations (UEQM) on resource units (RUs) of a given MRU. Therefore, there is a need for a solution of proportional round robin segment parser designs for the new wider bandwidths and new MRU combinations with either equal modulation (EQM) or unequal modulation (UEQM).

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. 27 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. 27.
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 be an access point (AP) STA or, alternatively, either of STA 110 and STA 120 may function as 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 802.11be and future-developed standards). Each of STA 110 and STA 120 may be configured to communicate with each other by utilizing the proportional round robin segment parser designs for the wider bandwidths and corresponding MRU combinations with either EQM or UEQM 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.
In IEEE 802.11be, segment parsing may be performed for RUs and/or MRUs of sizes greater than a 996-tone RU (RU996), such as 2×996, 996+484, 996+484+242, 2×996+484, 3×996+484, and 4×996. The segment parser in wireless communications under IEEE 802.11be is operated for equal modulation across all the RUs in a given MRU, in that: s=max (1, Nbpscs,u/2) for user u, with the same s being used for all the RUs in a given MRU. Here, NBPSCS,u denotes a number of coded bits per subcarrier per spatial stream for user u, NBPSCS,I,u denotes a number of coded bits per subcarrier per spatial stream for frequency subblock index/for user u, and NCBPSS,I,u denotes a number of coded bits per orthogonal frequency-division multiplexing (OFDM) symbol per spatial stream for frequency subblock index/for user u. The segment parser outputs a bit sequence distribution that can be expressed by Expression 1 as follows:
If there are leftover bits, the leftover bits may be processed in a round robin fashion as shown in Expression 2 below (which may be reused for UEQM):
Under various proposed schemes in accordance with the present disclosure, the processing for EQM and UEQM for wider bandwidths (e.g., 480 MHz and 640 MHz) by a proportional round robin segment parser may be operated the same as the segment parser under IEEE 802.11be as described above. That is, the formulae/equations of segment parsing in IEEE 802.11be may be reused with minor modifications by replacing all instances of NBPSCS,u with NBPSCS,I,u for UEQM, where/denotes the frequency segment or subblock index. Under the proposed schemes, NBPSCS,I,u may be associated with different modulations in different RUs in different frequency segments/frequency subblocks.
FIG. 2 illustrates an example scenario 200 under a proposed scheme in accordance with the present disclosure. Scenario 200 may pertain to modifications of an IEEE 802.11be segment parser processing for UEQM. Under the proposed scheme, the segment parser processing for UEQM may be operated in a way that is the same as that under IEEE 802.11be. Thus, Expression 1 shown above of segment parser in IEEE 802.11be may be reused with minor modifications by replacing all NBPSCS,u with NBPSCS,I,u. Here, I denotes a frequency segment or subblock index and NBPSCS,I denotes a number of coded bits per subcarrier spacing for a respective frequency segment or subblock index for user u. Under the proposed scheme, NBPSCS,I,u may be associated with different modulations in different RUs/MRUs in different frequency segments or frequency subblocks. Similarly, Expression 2 shown above may be reused for processing leftover bits for UEQM. FIG. 2 shows the minor modifications made to an IEEE 802.11be segment parser for supporting UEQM. In FIG. 2, the term “DCM” refers to dual-carrier modulation.
FIG. 3 illustrates an example design 300 under a proposed scheme in accordance with the present disclosure. Design 300 may pertain to physical-layer parameters NCBPSS,I,u (number of coded bits per OFDM symbol per spatial stream) for a proportional round robin segment parser used for EQM. Here, L denotes a number of 80 MHz frequency segments or frequency subblocks utilized or otherwise occupied by RUs of the respective MRU, I denotes a frequency segment or subblock index (with/=0, 1, . . . 7), and NCBPSS,I,u denotes a number of coded bits per OFDM symbol per spatial stream for a respective frequency segment or subblock index/for user u.

Illustrative Processes
FIG. 27 illustrates an example process 2700 in accordance with an implementation of the present disclosure. Process 2700 may represent an aspect of implementing various proposed designs, concepts, schemes, systems and methods described above. More specifically, process 2700 may represent an aspect of the proposed concepts and schemes pertaining to proportional round robin segment parser designs for the wider bandwidths and corresponding MRU combinations with either EQM or UEQM in wireless communications in accordance with the present disclosure. Process 2700 may include one or more operations, actions, or functions as illustrated by one or more of blocks 2710 and 2720. Although illustrated as discrete blocks, various blocks of process 2700 may be divided into additional blocks, combined into fewer blocks, or eliminated, depending on the desired implementation. Moreover, the blocks/sub-blocks of process 2700 may be executed in the order shown in FIG. 27 or, alternatively, in a different order. Furthermore, one or more of the blocks/sub-blocks of process 2700 may be executed repeatedly or iteratively. Process 2700 may be implemented by or in apparatus 2610 and apparatus 2620 as well as any variations thereof. Solely for illustrative purposes and without limiting the scope, process 2700 is described below in the context of apparatus 2610 implemented in or as STA 110 and apparatus 2620 implemented in or as STA 120 of a wireless network such as a WLAN in network environment 100 in accordance with one or more of IEEE 802.11 standards. It is noteworthy that, although the description of process 2700 below is provided in the context of apparatus 2610 (implemented in or as a non-AP STA) performing various operations, the same may be applicable to apparatus 2620 (implemented in or as an AP STA). Process 2700 may begin at block 2710.
At 2710, process 2700 may involve processor 2612 of apparatus 2610 (e.g., STA 110) generating an MRU comprising an aggregate of a plurality of RUs. Process 2700 may proceed from 2710 to 2720.
At 2720, process 2700 may involve processor 2612 transmitting, via transceiver 2616, the MRU with EQM or with UEQM in a bandwidth of 480 MHz or greater.
In some implementations, in generating the MRU, process 2700 may involve processor 2612 segment parsing data tones of the plurality of RUs of the MRU in a proportional round robin fashion with the EQM. In some implementations, in transmitting the MRU, process 2700 may involve processor 2612 transmitting the MRU with the EQM by applying a same modulation to the plurality of RUs across a plurality of frequency segments or frequency subblocks in the bandwidth.
In some implementations, in generating the MRU, process 2700 may involve processor 2612 segment parsing data tones of the plurality of RUs of the MRU in a proportional round robin fashion with the UEQM. In some implementations, in transmitting the MRU, process 2700 may involve processor 2612 transmitting the MRU with the UEQM by applying two or more different modulations to two or more RUs of the plurality of RUs across a plurality of frequency segments or frequency subblocks in the bandwidth.
In some implementations, in generating the MRU, process 2700 may involve processor 2612 generating: (a) twelve 484-tone RUs of the MRU to be transmitted in a 480 MHz bandwidth; or (b) six 996-tone RUs of the MUR to be transmitted in the 480 MHz bandwidth; or (c) sixteen 484-tone RUs of the MRU to be transmitted in a 640 MHz bandwidth; or (d) eight 996-tone RUs of the MUR to be transmitted in the 640 MHz bandwidth.
In some implementations, in generating the MRU, process 2700 may involve processor 2612 generating the MRU with a one-hole puncture (e.g., one continuous puncture). In such cases, the MRU may include: (a) five 996-tone RUs plus one 484-tone RU to be transmitted in a 480 MHz bandwidth; or (b) five 996-tone RUs to be transmitted in the 480 MHz bandwidth; or (c) four 996-tone RUs to be transmitted in the 480 MHz bandwidth; or (d) four 996-tone RUs plus one 484-tone RU to be transmitted in the 480 MHz bandwidth; or (e) seven 996-tone RUs to be transmitted in a 640 MHz bandwidth; or (f) six 996-tone RUs to be transmitted in the 640 MHz bandwidth; or (g) five 996-tone RUs to be transmitted in the 640 MHz bandwidth; or (h) four 996-tone RUs to be transmitted in the 640 MHz bandwidth; or (j) seven 996-tone RUs plus one 484-tone RU to be transmitted in the 640 MHz bandwidth; or (k) six 996-tone RUs plus one 484-tone RU to be transmitted in the 640 MHz bandwidth.
In some implementations, in generating the MRU, process 2700 may involve processor 2612 generating the MRU with a two-hole puncture (e.g., two discontinuous punctures). In such cases, the MRU may include: (a) four 996-tone RUs plus one 484-tone RU to be transmitted in a 480 MHz bandwidth; or (b) six 996-tone RUs to be transmitted in a 640 MHz bandwidth; or (c) four 996-tone RUs to be transmitted in the 640 MHz bandwidth; or (d) six 996-tone RUs plus one 484-tone RU to be transmitted in the 640 MHz bandwidth.
Additional Notes
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.
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.
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.”
From the foregoing, it will be appreciated that various implementations of the present disclosure have been described herein for purposes of illustration, and that various modifications may be made without departing from the scope and spirit of the present disclosure. Accordingly, the various implementations disclosed herein are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
