Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure is part of a non-provisional patent application claiming priority to U.S. Provisional Patent Application No. 63 / 350,707, filed on June 9, 2022, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates generally to wireless communications and, more particularly, to wide bandwidth resource unit (RU) tone planning design for next generation wireless local area networks (WLANs). Background Art

[0004] Unless otherwise indicated herein, the approaches described in this section are not prior art to the claims listed below and are not admitted to be prior art by inclusion in this section.

[0005] In wireless communications such as Wi-Fi (or WiFi) according to the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, wider bandwidth is often an effective way to achieve higher throughput for next generation WLANs. However, currently, there is no defined design for RU tone planning for wider bandwidths such as 240 MHz, 480 MHz, 560 MHz, and 640 MHz. Therefore, a solution for wide bandwidth RU tone planning design for next generation WLANs is needed. Summary of the invention

[0006] 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 the concepts, key points, benefits, and advantages of the novel and non-obvious technologies described herein. Selected implementations are further described in the detailed description below. Therefore, the following summary is not intended to identify essential features of the claimed subject matter, nor is it intended to be used to determine the scope of the claimed subject matter.

[0007] The purpose of the present disclosure is to provide solutions, concepts, designs, techniques, methods and devices related to wide bandwidth RU tone planning and design for next generation WLANs.

[0008] In one aspect, a method may involve generating subcarrier indices for RU tone planning for a wide bandwidth greater than 80 MHz with a subcarrier spacing (SCS) of 78.125 kHz by using a formula. The method may also include communicating wirelessly in the wide bandwidth.

[0009] In another aspect, a method may involve generating subcarrier indices for RU tone planning of a wide bandwidth greater than 80 MHz with a subcarrier spacing (SCS) of 78.125 kHz by using a formula. The method may also include communicating wirelessly in the wide bandwidth. In the case where the RU tone planning involves a 240 MHz bandwidth, the RU tone planning may involve truncating a continuous 80 MHz bandwidth from a 320 MHz bandwidth. In the case where the RU tone planning involves a 480 MHz bandwidth, the RU tone planning may involve truncating a continuous 160 MHz bandwidth from a 640 MHz bandwidth.

[0010] In yet another aspect, an apparatus may include a transceiver configured to perform wireless communication and a processor coupled to the transceiver. The processor may generate a subcarrier index for a RU tone plan for a wide bandwidth greater than 80 MHz with an SCS of 78.125 kHz by using a formula. The processor may communicate wirelessly in the wide bandwidth via the transceiver.

Figures 1 to 15 The following descriptions of various suggested approaches are provided.

[0034] Reference Figure 1, the network environment 100 may include at least a station (STA) 110 and a STA 120 for wireless communication. Either of the STA 110 and the STA 120 may be a non-access point (non-AP) STA, or alternatively, either of the STA 110 and the STA 120 may be used as an access point (AP) STA. In some cases, the STA 110 and the STA 120 may be associated with a Basic Service Set (BSS) according to one or more IEEE 802.11 standards (e.g., IEEE 802.11be and future developed standards). Each of the STA 110 and the STA 120 may be configured to communicate with each other by utilizing a wide bandwidth RU tone planning design of a next generation WLAN according to various proposed schemes described below. That is, either or both of the STA 110 and the STA 120 may act as a "user" in the proposed scheme and the examples described below. It is worth noting that, although various proposed schemes may be described separately or independently below, in actual implementation, some or all of the proposed schemes may be utilized or otherwise jointly implemented. Of course, each of the proposed schemes may be used or otherwise implemented separately or independently.

[0035] Under various proposed schemes according to the present disclosure, the RU tone plan of BW80 in IEEE 802.11be can be used as a basic building block to generate RU tone plans for wider bandwidths such as BW240, BW480, and BW640. The design can maintain the RU hierarchy as in IEEE802.11ax / be. Under the proposed scheme, RU bw80 Representing the RU tone plan in BW80 in IEEE 802.11be, the RU tone plan for a wide bandwidth greater than 80 MHz with a subcarrier spacing (SCS) = 78.125 kHz can be generated as follows: RU bw80 +512+n*1024. Here, for BW160, n=-1, 0; for BW240, n=-1.5, -0.5, 0.5; for BW320, n=-2, -1, 0, 1; for BW480, n=-3, -2, -1, 0, 1, 2; for BW640, n=-4, -3, -2, -1, 0, 1, 2, 3. That is, by assuming SCS=78.125kHz, for a wide bandwidth greater than 80MHz, the RU subcarrier index for a given RU type can be generated as follows:

[0036] RU wbw，i =RU bw80，j +512+n*1024

[0037] Here, i=1, 2, 3, 4, ..., N ru，bw , represents the RU index for wider bandwidth; j = mod(i-1, N ru，bw80 )+1, indicating the RU index for BW80; RU bw80，j Indicates that it is used for Figure 2 The subcarrier index of a given RU size / type in BW80 with RU index j as defined in Table 200 shown; and N ru，bw Indicates the number of RUs for a given RU type in a given bandwidth. Figure 3 Table 300 in FIG. 3 shows N for different RU types and different bandwidths. ru，bw For any given wider bandwidth, the RU subcarrier index can be generated by using the above formula-based method under the proposed scheme (as in the style of IEEE 802.11be).

[0184] The subject matter described herein sometimes shows different components contained in or connected to different other components.It should be understood that the described architecture is only an example, and many other architectures of the same function can actually be realized.In the sense of conception, any setting of the components realizing the same function is effectively "associated" so as to realize the desired function.Therefore, any two components combined to realize a specific function herein can be regarded as "associated" with each other so as to realize the desired function, regardless of the architecture or intermediate components.Similarly, any two components so associated can also be regarded as "operably connected" or "operably coupled" to realize the desired functionality, and any two components that can be so associated can also be regarded as "operably coupled" to realize the desired functionality.Specific examples of operable coupling include but are not limited to physically matchable and / or physically interactive components and / or wirelessly interactive and / or wirelessly interactive components and / or logically interactive and / or logically interactive components.

[0185] In addition, with respect to the use of substantially any plural and / or singular terms herein, those skilled in the art may translate from the plural to the singular and / or from the singular to the plural as appropriate, depending on the context and / or application. For clarity, various singular / plural arrangements may be expressly set forth herein.

[0186] Furthermore, those skilled in the art will appreciate that, in general, the terms used herein, and particularly in the appended claims, such as the 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," and the term "comprising" should be interpreted as "including but not limited to." Those skilled in the art will further appreciate that if a specific number of introduced claim recitations is intended, such an intent will be explicitly recited in the claim, and in the absence of such a recitation, no such intent is present. For example, to aid understanding, the following appended claims may contain the use of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be interpreted as implying that a claim recitation introduced by the indefinite article "a" or "an" will limit 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., "one" and / or "an" should be interpreted as meaning "at least one" or "one or more"; the same applies to the use of explicit articles introducing claim recitations. Furthermore, even if a specific number of an introduced claim recitation is explicitly recited, one skilled in the art will recognize that such a recitation should be interpreted as meaning at least the recited number, e.g., a bare recitation of "two recitations" without other modifiers means at least two recitations, or two or more recitations. Again, in those cases, the convention is similar to "at least one of A, B, and C, etc." In general, such constructions are used in the sense that one skilled in the art understands the convention, e.g., "a system having at least one of A, B, and C" will include but is not limited to systems having 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 cases where the convention is similar to "at least one of A, B, or C". In general, such constructions are intended to be used in the sense that one skilled in the art understands the convention, e.g., "a system having at least one of A, B, or C" will include but is not limited to systems having 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. One skilled in the art will further understand that any disjunctive words and / or phrases that actually present two or more alternative terms, whether in the specification, claims, or drawings, should be understood to encompass the possibility of including 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 possibility of "A" or "B" or "A and B".

[0187] From the above, it will be appreciated that various embodiments of the present invention have been described herein for illustrative purposes, and various modifications may be made without departing from the scope and spirit of the present invention. Therefore, the various implementations disclosed herein are not intended to be limiting, and their true scope and spirit are indicated by the appended claims.
