Description

TECHNICAL FIELD

[0001] The present disclosure relates generally to wireless communications, and more specifically to design simplification of distributed-tone resource units (dRUs) in 6 GHz low-power indoor (LPI) systems. BACKGROUND

[0002] Unless otherwise indicated herein, the methods described in this section are not prior art to the claims listed below and cannot be admitted to be prior art merely by inclusion in this section.

[0003] According to the existing regulations of the Federal Communications Commission (FCC) on wireless communications in the 2.4 GHz and 5 GHz bands, the equivalent isotropically radiated power (EIRP) upper limit for 2 MHz transmission power spectral density (PSD) is 20 dBm, and the transmission (Tx) power limit upper limit is 30 dBm. Assuming a reasonable Tx power, the FCC requirement will not limit the Tx power of narrow bandwidth transmission. On the other hand, the FCC requirements for 6 GHz low-power indoor (LPI) applications are much more stringent than the PSD requirements for the 2.4 GHz and 5 GHz bands. For example, the EIRP limit for an access point (AP) in 6 GHz LPI is 5 dBm / MHz, while the EIRP limit for an AP in the 5 GHz band is 17 dBm / MHz. Likewise, the EIRP limit for a non-AP in 6 GHz LPI is -1 dBm / MHz, while the EIRP limit for an AP in the 5 GHz band is 11 dBm / MHz. Therefore, in order to increase the Tx power and improve the coverage of the 6 GHz LPI system, a solution is needed to design the tone-distributed RU in the 6 GHz LPI system. SUMMARY

[0004] The following summary is illustrative only and is not intended to be limiting in any way. That is, the following summary is provided to introduce some of the concepts, highlights, benefits, and advantages of the novel and non-obvious technology described herein. Selected implementations are described further in the detailed description of the specific embodiments below. As such, the following summary is not intended to determine key or essential features of the claimed subject matter nor does it limit the scope of the claimed subject matter.

[0005] It is an object of the present disclosure to provide solutions, concepts, designs, techniques, methods, and apparatuses related to design simplification of tone-distributed RUs in 6GHz LPI systems. Under one proposed solution according to the present disclosure, a tone-distributed RU can be generated using a shift from a "base tone set." Under another proposed solution according to the present disclosure, a tone-distributed RU can be generated using a uniform formula using parameters given by logical RU size and distribution bandwidth. Under yet another proposed solution according to the present disclosure, the logical RU size for tone distribution can be limited. Under yet another proposed solution according to the present disclosure, the bandwidth over which tone distribution is applied can be limited. It is believed that the above problems can be addressed by implementing one or more of the various solutions proposed herein.

[0006] In one aspect, a method can involve performing tone distribution of RUs having a logical RU size and / or Multi-RUs (MRUs) having a MRU size over a bandwidth to generate tone-distributed RUs and / or tone-distributed MRUs. The method can also involve using the tone-distributed RUs and the tone-distributed MRUs for wireless communication in a 6GHz LPI system.

[0007] In another aspect, an apparatus can include a transceiver configured for wireless communication and a processor coupled to the transceiver. The processor can perform tone distribution of RUs having a logical RU size and / or Multi-RUs (MRUs) having a MRU size over a bandwidth to generate tone-distributed RUs and / or tone-distributed MRUs. The processor can also communicate, via the transceiver, using the tone-distributed RUs and the tone-distributed MRUs in a 6GHz LPI system.

[0008] It is worth noting that while the description provided herein can be in the context of certain radio access technologies, networks, and network topologies (e.g., Wi-Fi), the proposed concepts, solutions, and any variants / derivatives thereof can be implemented in, used for, or by other types of radio access technologies, networks, and network topologies, such as, but not limited to, Bluetooth, ZigBee, Fifth Generation (5G) / New Radio (NR), Long-Term Evolution (LTE), LTE-Advanced, LTE-Advanced Pro, Internet-of-Thing (IoT), Industrial IoT (IIoT), and narrowband IoT (NB-IoT). Thus, the scope of the present invention is not limited to the examples described herein.

[0009] The present invention can use tone dispersed RUs and / or tone dispersed MRUs for wireless communication. The present invention can increase the transmission power of an LPI system, and thus enhance the coverage of the LPI system, by using tone dispersed RUs and / or tone dispersed MRUs for wireless communication.

[0029] Detailed embodiments and implementations of claimed subject matter are disclosed herein. It should be understood, however, that the disclosed embodiments and implementations are merely examples of the claimed subject matter. The invention can be embodied in many different forms and should not be construed as limited to the exemplary embodiments and implementations set forth herein. These exemplary embodiments and implementations are provided so that this disclosure will be thorough and complete, and fully convey the scope of the invention to those skilled in the art. In the following description, details of well-known features and techniques can be omitted to avoid unnecessarily obscuring the presented embodiments and implementations.

[0030] Embodiments according to the present application relate to various techniques, methods, schemes and / or solutions related to design simplification of tone dispersed RUs in 6GHz LPI systems. According to the present application, a variety of possible solutions can be implemented individually or jointly. That is, while the following can describe these possible solutions separately, two or more of these possible solutions can be implemented in one combination or another.

[0031] It is worth noting that in the present application, a regular RU of 26 tones can be interchangeably denoted as RU26, a regular RU of 52 tones can be interchangeably denoted as RU52, a regular RU of 106 tones can be interchangeably denoted as RU106, a regular RU of 242 tones can be interchangeably denoted as RU242, and so on. In addition, a regular MRU of aggregated (26+52) tones can be interchangeably denoted as MRU78, a regular MRU of aggregated (26+106) tones can be interchangeably denoted as MRU132, and so on. Furthermore, in the present application, a tone dispersed RU of 26 tones can be interchangeably denoted as dRU26, a tone dispersed RU of 52 tones can be interchangeably denoted as dRU52, a tone dispersed RU of 106 tones can be interchangeably denoted as dRU106, a tone dispersed RU of 242 tones can be interchangeably denoted as dRU242, and so on. In addition, a tone dispersed MRU of aggregated (26+52) tones can be interchangeably denoted as dMRU78, a tone dispersed MRU of aggregated (26+106) tones can be interchangeably denoted as dMRU132, and so on. Since the above examples are merely illustrative examples and not an exhaustive list of all possibilities, this is equally applicable to regular RUs, tone dispersed RUs, MRUs and tone dispersed MRUs of different sizes (or different number of tones). It is also worth noting that in the present application, a bandwidth of 20MHz can be interchangeably denoted as BW20, a bandwidth of 40MHz can be interchangeably denoted as BW40, a bandwidth of 80MHz can be interchangeably denoted as BW80, a bandwidth of 160MHz can be interchangeably denoted as BW160, a bandwidth of 240MHz can be interchangeably denoted as BW240, and a bandwidth of 320MHz can be interchangeably denoted as BW320. The present application provides a communication method, comprising: performing tone distribution of a regular RU having a logical resource unit RU size and / or a multiple resource unit MRU having a MRU size over a bandwidth to generate a tone dispersed RU and / or a tone dispersed MRU; and using the tone dispersed RU and / or the tone dispersed MRU for wireless communication in a 6GHz low power indoor LPI system. The method is capable of using the tone dispersed RU and the tone dispersed MRU for wireless communication. By using the tone dispersed RU and the tone dispersed MRU for wireless communication, the transmission power of the LPI system can be increased, thereby enhancing the coverage of the LPI system.

[0032] Figure 1 An example network environment 100 is shown in which various solutions and schemes according to the present application can be implemented. Figures 2-15 Example implementations of various proposed schemes in the network environment 100 according to the present application are shown. With reference to Figures 1-15 , various proposed schemes described later are provided.

[0033] With reference to Figure 1 , the network environment 100 can involve a communication entity 110 and a communication entity 120 for wireless communication (e.g., in a WLAN according to one or more IEEE 802.11 standards). For example, the communication entity 110 can be a first STA and the communication entity 120 can be a second STA, where each of the first and second STAs functions as an access point (AP) or a non-AP STA. Under various proposed schemes according to the present application, the communication entity 110 and the communication entity 120 can be configured to wirelessly communicate in a 6GHz LPI system in a distributed-tone RU with a simplified design, as described herein.

[0034] Under the proposed schemes according to the present application, a tone-distributed RU (herein interchangeably referred to as an interleaved RU and / or an interlaced RU) can be simply generated from a corresponding “base tone set” by shifting, given a distribution bandwidth and a logical RU size, which can be represented as follows:

[0035] K td = k td_base (k) + k shift (r)

[0036] Herein, r denotes a logical RU index, r = 1, 2, 3, …, N ru ; k denotes a subcarrier index, k = 0, 1, 2, … N st ; N ru denotes a number of logical RUs of a given logical RU size in a given bandwidth (e.g., in BW20, N ru = 9 for RU26, N ru = 4 for RU52); N st denotes a total number of subcarriers (including data tones and pilot tones) corresponding to a logical RU size (e.g., N st = 26 for RU26, N st = 52 for RU52, and N st = 106 for RU106); ktd_base denotes a basic tone set (vector) corresponding to a given bandwidth and logical RU size; k shift denotes an offset value (vector); and K td denotes subcarrier indices after tone distribution. Accordingly, adjacent tones of a logical RU (e.g., RU 26 over 2MHz) can be spread or otherwise distributed over a wider bandwidth (e.g., 20MHz, 40MHz, or 80MHz). Beneficially, multiple tones (e.g., 26 tones of RU 26) can be distributed so that there is at least one tone per 1MHz bandwidth in the distributed bandwidth.

[0037] In some examples, a basic tone set k td_base may be generated by (1) first applying a logical RU index r to a tone-distributed RU mapping to obtain a tone-distributed RU index output i = π(r), and (2) generating subcarrier indices of the tone-distributed RU according to i. For example, for BW20, i = (13(r - 1)) mod 9 + 1, where r = 1, 2,..., 9, and π() denotes a mapping or permutation function.

[0038] Under the proposed scheme, for a tone distribution of a basic set of 26-tone tone-distributed RU (dRU26) over BW20, k td_base = [0:9:225], k shift = [0 5 1 6 4 7 2 8 3], r = 1, 2,..., 9, where in one implementation, 0 denotes a starting tone, 225 denotes an ending tone, and 9 denotes a step size, and the tones of dRU26 include tone indices 0, 9, 18,... when k shift = 0; the tones of dRU26 include tone indices 5, 14, 23,... when k shift = 5.

[0043] Figure 2 An example table 200 summarizing various scenarios under the proposed scheme according to the present application is shown. Reference is made to Figure 2Each number shown in Table 200 represents the number of tones in a 1 MHz sliding window for a logical RU distributed over a given bandwidth (referred to herein as "distributed bandwidth" or "distribution bandwidth" or "dispersed bandwidth"). In the proposed scheme, a distributed-tone RU can be generated or operated in one of the various scenarios summarized in Table 200. In a first scenario, both distributed-tone RUs (dRUs) and distributed-tone MRUs (dMRUs) are supported, with the operating regions highlighted or shaded in Table 200. In a second scenario, the applicable logical RUs can be limited to RUs 26, 52, and 106 for a distribution bandwidth BW20, to RUs 26, 52, 106, and 242 for a distribution bandwidth BW40, and to RUs 26, 52, 106, 242, and 484 for a distribution bandwidth BW80.

In a sixth scenario, the applicable logical RUs can be limited to RUs 52, 106, 242, and 484, with tone distribution applicable to BW80 (or RU996) but not to other bandwidths.

[0044] Figure 3 An example table 300 summarizing various scenarios under the proposed scheme according to the present application is shown. Referring to Figure 3 Each number shown in Table 300 represents the number of tones in a 1 MHz sliding window for a logical RU distributed over a distribution bandwidth. In the proposed scheme, a distributed-tone RU can be operated in one of the various scenarios summarized in Table 300. In a first scenario, the operating regions are highlighted or shaded in Table 300. In a second scenario, all logical RUs up to RU996 can be applicable, with no limit on the distribution bandwidth, which can be up to BW320 (or RU4*996).

[0045] Under the proposed scheme according to the present application, the RU with tone dispersion can be generated from the following equation given the distributed bandwidth and logical RU size:

[0046] K td (k) = RU start (r) + l i + j*N p

[0047] where N p denotes the period; l i denotes the tone distribution pattern within the period; i = 0, 1, 2,..., L - 1; k = 0, 1, 2,..., N st_ru - 1; r = 1, 2,..., N ru , where r is the logical RU index. In addition, l i ∈ Ω ru = {l0, l1,..., l L-1}; L = |Ω ru |; for RU26, RU52, RU106, RU242, RU484, RU996, N st_ru are 26, 52, 106, 242, 484, 996, respectively. Under the proposed scheme, RU start (r) denotes the first or starting tone index of dRUr; l i denotes the tone within a repetition distance or a repetition period; N p denotes the repetition distance or the repetition period; L denotes the number of tones within a repetition distance or a repetition period; N st_ru denotes the number of subcarriers for dRU; and N ru denotes the number of RUs for a given RU size in a given bandwidth. Figure 4 An example table 400 showing the number of RUs for various RU sizes under the proposed scheme according to the present application with respect to various bandwidths is shown.

[0048] Under the proposed scheme according to the present application, two design options can be taken. The first option (Option A) can be a simple design which can achieve perfect uniform tone distribution and also suboptimal or optimal power boosting performance, but with some limitations. The second option (Option B) can provide the best scheduling flexibility and can achieve optimal power boosting performance.

[0049] Under the proposed scheme, for BW20, the first option can need to support RUs 26, 52, and 106 without supporting other (e.g., larger) RUs or MRUs, with tones uniformly distributed to achieve optimal or suboptimal performance. For BW40, the first option can need to support RUs 26, 52, 106, and 242 without supporting other (e.g., larger) RUs or MRUs, with tones uniformly distributed to achieve optimal or suboptimal performance. For BW80, the first option can need to support RUs 26, 52, 106, 242, and 484 without supporting other (e.g., larger) RUs or MRUs, with tones uniformly distributed to achieve optimal performance. For BW160, the first option can need to support RUs 52, 106, 242, 484, and 996 without supporting other RUs or MRUs, with tones uniformly distributed to achieve optimal performance. For BW320, the first option can need to support RUs 106, 242, 484, and 996 without supporting other (e.g., smaller) RUs or MRUs, with tones uniformly distributed to achieve optimal performance.

Figure 7 (B) of FIG. 3 shows a summary of tone distribution design parameters for the first option under BW320.

[0051] Under the proposed scheme, for BW20, the second option can need to support all RUs and small MRUs to achieve optimal performance. For BW40, the second option can need to support all RUs and small MRUs to achieve optimal performance. For BW80, the second option can need to support all RUs and small MRUs to achieve optimal performance. For BW160, the second option can need to support all RUs and small MRUs to achieve optimal performance. For BW320, the second option can need to support all RUs and small MRUs to achieve optimal performance. The MRUs of tone-spreading can be generated from the corresponding RUs of tone-spreading.

Figure 10A , Figure 10B , Figure 10C and Figure 10D Each of alternative example scenarios 1000A, 1000B, 1000C and 1000D under the proposed scheme is shown, respectively. Specifically, Figure 10A , Figure 10B , Figure 10C and Figure 10D Each shows a respective parameter summary of tone distribution design under the second option for BW80.

Figure 12 An example scenario 1200 under the proposed scheme is shown. Specifically, Figure 12 A parameter summary of tone distribution design under the second option for BW320 is shown.

[0053] Under the proposed scheme according to the present invention, alternative design methods and / or equations can be utilized to generate tone distributions. Under the first option (Option A) of the proposed scheme, assuming tone distributions are applied to BW80, instead of other bandwidths, for RUs 52, 106, 242 and 484, then the tone distributions can be further simplified to achieve perfect and uniform distribution of tones based on alternative formulas (shown below):

[0054] K td = RU start (r) + j*D td

[0055] Here, j = 0, 1, 2,..., N st - 1, r = 1, 2, 3,..., N ru . Also, D td represents the tone spacing distance, D td = 16 for RU 52, D td = 8 for RU 242, and D td = 4 for RU 484. Also, RU start can be the same as shown in Figure 6 .

[0056] Similarly, under the first option of the proposed scheme, the alternative formulas shown above can also be used to generate the tone distribution if, for RU 106, RU 242, RU 484, and RU 996, the tone distribution is assumed to apply to BW 160 instead of other bandwidths, or for RU 242, RU 484, and RU 996, the tone distribution is assumed to apply to BW 320 instead of other bandwidths. Specifically, for BW 160, D td = 16 for RU 106, D td = 8 for RU 242, D td = 4 for RU 484, and D td = 2 for RU 996. Also, for BW 320, D td = 16 for RU 242, D td = 8 for RU 484, and D td = 4 for RU 996. Also, RU start can be the same as shown in Figure 7 .

[0057] Under the first option of the proposed scheme, if extra small RUs are supported on larger bandwidths (e.g., RU 26 on BW 80, RU 26 or RU 52 on BW 160), two approaches can be applied. In the first approach, larger D td can be used for the alternative formulas shown above. For example, D td = 32 can be used for distributing RU 26 on BW 80, but is limited to at most 32 RU 26. Similarly, D td = 32 can be used for distributing RU 52 on BW 160 and distributing RU 106 on BW 320, but is not limited thereto. In the second approach, smaller D td (e.g., Dtd = 16) can be used for small RUs (e.g., RU26, RU52, and RU106) on larger bandwidths. In this case, small RUs can be distributed within a “segment” using the following formula:

[0058]

[0059] Here, N seg denotes the segment size, which is defined using the number of tones, N seg = 484 or 996. Under the second option (Option B) of the proposed scheme, another alternative method can be utilized to generate the scattered tone RUs by using the following formula:

[0060]

[0061] Here, j = 0, 1, 2,..., N st - 1, r = 1, 2, 3,..., N ru , N psf denotes the period of the tone shift, and N tsf denotes the number of tones per shift. Figure 13 An example scenario 1300 under the proposed scheme is shown. Specifically, Figure 13 A summary of parameters for the tone distribution design under the second option for BW20, BW40, and BW80 is shown.

[0098] 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 intermediate 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 connected", or "operably coupled", to each other to achieve the desired functionality. Specific examples of operably coupled include but are not limited to physical

[0099] 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 can be explicitly set forth herein for sake of clarity.

[0100] Furthermore, those skilled in the art will understand that the terms generally used herein, particularly those used in the appended claims, such as the body of the appended claims, are generally intended as “open-ended” terms. For example, the term “comprising” should be interpreted as “including but not limited to,” the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” and so on. Those skilled in the art will further understand that if a specific number of introduced claim elements are intended, such intent will be explicitly stated in the claim, and in the absence of such a statement, such intent does not exist. For example, to aid understanding, the appended claims may contain the use of the introductory phrases “at least one” and “one or more” to introduce claim elements. However, the use of such phrases should not be construed as implying that the claim element introduced by the indefinite article “a” or “an” limits any particular claim containing such an introduced claim element to containing only one such element, even when the same claim contains the introductory phrase “one or more” or “at least one” and the indefinite article such as “a” or “an,” for example, “a” and / or “an” should be interpreted as referring to “at least one” or “one or more,” and the same applies to the use of definite articles used to introduce claim elements. Furthermore, even when a specific number of the introduced claim elements are explicitly stated, those skilled in the art will recognize that such a statement should be interpreted as meaning at least the number listed. For example, the statement "two elements" without other modifiers means at least two elements or two or more elements. Additionally, in the use of phrases like "at least one of A, B, and C," for its purpose, such a structure is generally understood by those skilled in the art to be conventional. For example, "the system has at least one of A, B, and C" will include, but is not limited to, the system having a single A, a single B, a single C, A and B together, A and C together, B and C together, and / or A, B, and C together, etc. Similarly, in the use of phrases like "at least one of A, B, or C," for its purpose, such a structure is generally understood by those skilled in the art to be conventional. For example, "the system has at least one of A, B, or C" will include, but is not limited to, the system having a single A, a single B, a single C, A and B together, A and C together, B and C together, and / or A, B, and C together, etc. Those skilled in the art will further understand that any transitional words and / or phrases that actually represent two or more options, whether in the specification, claims, or drawings, should be understood to include the possibility of including one of a plurality of terms, any one of a plurality of terms, or two terms. For example, the phrase “A or B” will be understood to include the possibility of “A” or “B” or “A and B”.
