FIELD
[002] [002] Certain aspects of the present disclosure relate, in general, to wireless communication and, more particularly, to methods and devices for communication through 320 MHz sub-bands. BACKGROUND
[003] [003] In many telecommunication systems, communication networks are used to exchange messages between several spatially separate interaction devices. Networks can be classified according to geographic scope, which could be, for example, a metropolitan area, a local area or a personal area. Such networks could be designated respectively as a wide area network (WAN), metropolitan area network (MAN), local area network (LAN), or personal network (PAN). Networks also differ according to the switching / routing technique used to interconnect the various network nodes and devices (for example, circuit switching vs. packet switching), the type of physical media used for transmission (for example, wired vs. wireless), and the set of communication protocols used (for example, set of Internet protocols, SONET (Synchronous Optical Network), Ethernet, etc.).
[004] [004] Wireless networks can be preferred when network elements can be mobile and thus have dynamic connectivity needs, or if the network architecture is formed in a topology for this purpose, instead of being posted. Wireless networks employ intangible physical media in an unguided propagation mode using electromagnetic waves in the radio, microwave, infrared, optical frequency bands, etc. Wireless networks advantageously facilitate user mobility and fast field installation when compared to attached wired networks.
[005] [005] The devices on a wireless network can transmit / receive information among themselves. Device transmissions can interfere with each other, and certain transmissions can selectively block other transmissions. When many devices can be on a communication network, congestion and inefficient use of the link can result. Thus, non-temporary computer-readable systems, methods and means may be necessary to improve the efficiency of communication in wireless networks. SUMMARY

[0054] [0054] Various aspects of innovative systems, devices and methods are described more fully later in this document with reference to the attached drawings. This disclosure can, however, be incorporated in many different ways and should not be construed as limited to any specific structure or function presented throughout this disclosure. Instead, these aspects are provided so that this disclosure is meticulous and complete and will completely convey the scope of the disclosure to those skilled in the art. Based on the indications in this document, the person skilled in the art should assess that the scope of the disclosure is intended to cover any aspect of the innovative systems, apparatus and methods disclosed in this document, whether implemented independently, or combined with any other aspect of the invention. For example, an apparatus can be implemented or a method can be practiced using any number of aspects presented in this document. In addition, the scope of the invention is intended to cover such an apparatus or method that is practiced using another structure, functionality or structure and functionality in addition to or different from the various aspects of the invention presented in this document. It should be understood that any aspect disclosed in this document may be incorporated by one or more elements of a claim.
[0055] [0055] Although particular aspects can be described in this document, many variations and permutations of these aspects are included within the scope of the disclosure. While some benefits and advantages of the preferred aspects may be mentioned, the scope of the disclosure is not intended to be limited to particular benefits, uses or purposes. Instead, aspects of the disclosure may be intended to be widely applicable to different wireless technologies, system configurations, networks and transmission protocols, some of which can be illustrated by way of example in the figures and in the following description of preferred aspects . The detailed description and drawings can be merely illustrative of the disclosure rather than limiting, the scope of the disclosure being defined by the appended claims and equivalents thereof. Implementation devices
[0056] [0056] Wireless network technologies can include various types of wireless local area networks (WLANs). A WLAN can be used to interconnect nearby devices together, employing widely used network protocols. The various aspects described in this document can be applied to any communication standard, such as Wi-Fi or, more generally, any member of the Institute of Electrical and Electronics Engineers (IEEE) 802.11 family of wireless protocols (for example, extremely high throughput) (EHT) also called ultra-high yield (UHT) in this document).
[0057] [0057] In some respects, wireless signals can be transmitted according to a highly effective 802.11 protocol using orthogonal frequency division multiplexing (OFDM) and direct sequence spreading spectrum (DSSS) communications, a combination of OFDM and DSSS communications or other schemes.
[0058] [0058] In some deployments, a WLAN includes several devices that can be the components that access the wireless network. For example, there can be two types of devices: access points ("APs") and clients (also referred to as stations or "STAs"). In general, an AP serves as a hub or base station for the WLAN and an STA serves as a WLAN user. For example,
[0059] [0059] The techniques described in this document can be used for various wireless broadband communication systems, including communication systems that can be based on an orthogonal multiplexing scheme. Examples of such communication systems include Space Division Multiple Access (SDMA), Time Division Multiple Access (TDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access systems (SC-FDMA), and so on. An SDMA system can use directions sufficiently different to simultaneously transmit data belonging to multiple user terminals. A TDMA system can allow multiple user terminals to share the same frequency channel by dividing the transmission signal into different time slots, each time slot being assigned to a different user terminal. A TDMA system can implement a global mobile communication system (GSM) or some other standards known in the art. An OFDMA system uses orthogonal frequency division multiplexing (OFDM), which is a modulation technique that divides the total bandwidth into multiple orthogonal subcarriers. These subcarriers can also be called tones, bins, etc. with OFDM, each subcarrier can be independently modulated with data. An OFDM system can implement IEEE
[0060] [0060] The techniques in this document can be incorporated (for example, implemented or performed) in a variety of wired or wireless devices (for example, nodes). In some respects, a wireless node implemented in accordance with the instructions in this document may comprise an access point or an access terminal.
[0061] [0061] An access point ("AP") may comprise, be implemented as, or known as NodeB, Radio Network Controller ("RNC"), eNodeB, Base Station Controller ("BSC"), Transceiver Base ("BTS"), Base Station ("BS"), Transceiver Function ("TF"), Radio Router, Radio Transceiver, Basic Service Set ("BSS"), Service Set
[0062] [0062] A station ("STA") can also comprise, be deployed as or be known as a user terminal, an access terminal ("AT"), a subscriber station, a subscriber unit, a mobile station, a remote station, a remote terminal, a user agent, a user device, user equipment or some other terminology. In some deployments, an access terminal may comprise a cell phone, a cordless phone, a Session Initiation Protocol ("SIP") phone, a local wireless circuit station ("WLL"), a personal digital assistant ("PDA"), a portable device that has wireless capability or some other suitable processing device connected to a wireless modem. Consequently, one or more aspects presented in this document can be incorporated into a telephone (for example, a cell phone or smartphone), a computer (for example, a portable computer), a portable communication device, a headset, a portable computing (for example, a personal data assistant), an entertainment device (for example, a music or video device or a satellite radio), a gaming device or system, a global positioning system device, or any other suitable device configured for wireless communication.
[0063] [0063] Figure 1 illustrates an example of a wireless communication system 100 in which aspects of the present disclosure can be employed. The wireless communication system 100 can operate according to a wireless standard, for example, the 802.11ax standard. The wireless communication system 100 may include an AP 104, which communicates with STAs 106.
[0064] [0064] A variety of processes and methods can be used for transmissions on the wireless communication system 100 between AP 104 and STAs 106. For example, signals can be transmitted and received between AP 104 and STAs 106 according to with OFDM / OFDMA techniques. If so, wireless communication system 100 can be referred to as an OFDM / OFDMA system. Alternatively, signals can be transmitted and received between AP 104 and STAs 106 according to code division multiple access (CDMA) techniques. If so, wireless communication system 100 can be referred to as a CDMA system.
[0065] [0065] A communication link that facilitates transmission from AP 104 to one or more of STAs 106 can be referred to as a downlink (DL) 108, and a communication link that facilitates transmission from one or more from STAs 106 to AP 104 can be referred to as an uplink (UL) 110. Alternatively, a downlink 108 can be called a direct link or a direct channel, and an uplink 110 can be called a reverse link or a reverse channel.
[0066] [0066] AP 104 can provide wireless communication coverage in a basic service area (BSA)
[0067] [0067] Figure 2 illustrates various components that can be used in a wireless device 202 that can be employed within wireless communication system 100. Wireless device 202 is an example of a device that can be configured to implement the various methods described in this document. For example, wireless device 202 may comprise AP 104 or one of STAs 106.
[0068] [0068] Wireless device 202 may include a processor 204 that controls the operation of wireless device 202. Processor 204 may also be called a central processing unit (CPU). A memory 206, which can include both read memory (ROM) and random access memory (RAM), provides instructions and data to processor 204. A portion of memory 206 can also include non-volatile random access memory (NVRAM). Processor 204 typically performs logical and arithmetic operations based on program instructions stored within memory 206. Instructions in memory 206 can be executable to implement the methods described in this document.
[0069] [0069] Processor 204 may comprise or be a component of a processing system implemented with one or more processors. The one or more processors can be implemented with any combination of general purpose microprocessors, microcontrollers, digital signal processors (DSPs), field programmable ports (FPGAs), programmable logic devices (PLDs), controllers, state machines, closed logic, discrete hardware components, finite state machines of dedicated hardware or any other suitable entities that can perform calculations or other information manipulation.
[0070] [0070] The processing system may also include machine-readable means for storing software. The software must be interpreted widely to mean any kind of instructions, whether it is called software, firmware, middleware, microcode, hardware description language, or otherwise. Instructions can include code (for example, in source code format, binary code format, executable code format, or any other suitable code format). The instructions, when executed by one or more processors, cause the processing system to perform the various functions described in this document.
[0071] [0071] The wireless device 202 may also include an enclosure 208 which may include a transmitter 210 and a receiver 212 to allow the transmission and reception of data between the wireless device 202 and a remote location. Transmitter 210 and receiver 212 can be combined to form a transceiver 214. An antenna 216 can be attached to cabinet 208 and electrically coupled to the transceiver
[0072] [0072] The wireless device 202 may also include a signal detector 218 which can be used in an attempt to detect and quantify the level of signals received by transceiver 214. The signal detector 218 can detect such signals as total energy, energy per subcarrier per symbol, spectral power density and other signals. Wireless device 202 may also include a digital signal processor (PSD) 220 for use in signal processing. The DSP 220 can be configured to generate a data unit for transmission. In some aspects, the data unit may comprise a physical layer data unit (PPDU). In some ways, the PPDU is called a package.
[0073] [0073] The wireless device 202 may additionally comprise a user interface 222 in some respects. User interface 222 may comprise a numeric keypad, microphone, speaker and / or screen. User interface 222 can include any element or component that transmits information to a user of wireless device 202 and / or receives user input.
[0074] [0074] The various components of wireless device 202 may be coupled by a 226 bus system. The 226 bus system may include a data bus, for example, as well as a power bus, a control signal bus and a bus of status signals in addition to the data bus.
[0075] [0075] Although several separate components can be illustrated in Figure 2, those skilled in the art will recognize that one or more components can be combined or commonly implemented. For example, processor 204 can be used to implement not only the functionality described above in relation to processor 204, but also to implement the functionality described above in relation to signal detector 218 and / or DSP 220. In addition, each of the components illustrated in Figure 2 can be implemented using a plurality of separate elements.
[0076] [0076] As discussed above, wireless device 202 may comprise an AP 104 or an STA 106, and may be used to transmit and / or receive communication. Communication shared between devices on a wireless network can include data units that can comprise packets or frames. In some respects, data units may include data frames, control frames and / or management frames. Data frames can be used to transmit data from an AP and / or an STA to other APs and / or STAs. Control boards can be used in conjunction with data boards to perform various operations and to send data reliably (for example, confirming data recognition, polling APs, area clearing operations, channel acquisition, maintenance functions). carrier detection, etc.). Management boards can be used for various supervisory functions (for example, to enter and leave wireless networks, etc.).
[0077] [0077] Certain aspects of the present disclosure support allowing APs 104 to allocate transmissions from STAs 106 in optimized ways to improve efficiency. High efficiency wireless (HEW) stations, which can also be called HE STAs, stations using an 802.11 high efficiency protocol (such as 802.11ax), and stations using older or legacy 802.11 protocols (such as 802.11 b), can compete or coordinate with each other to access a wireless medium. In some embodiments, the 802.11 high throughput protocol described in this document may allow HEW and legacy stations to interoperate according to various OFDMA tone planes (which can also be called tone maps). In some modalities, HEW stations can access the wireless medium more efficiently, such as using multiple access techniques in OFDMA. Consequently, in the case of densely populated apartment buildings or public spaces, APs and / or STAs using the high-efficiency 802.11 protocol may experience reduced latency and increased network throughput even though the number of active wireless devices increase, thereby improving the user experience.
[0078] [0078] In some embodiments, APs 104 can transmit wirelessly according to various tone plans from DL to HEW STAs. For example, with reference to Figure 1, STAs 106A to 106D can be STAs of
[0079] [0079] Figure 3 shows an example of a 2N tones plane 300, according to a modality. In one embodiment, the tone plane 300 corresponds to OFDM tones, in the frequency domain, generated using a fast Fourier transformation (FFT) of 2N points. The tone plane 300 includes 2N OFDM tones indexed -N to N-1. The tone plane 300 includes two sets of edge or guard tones 310, two sets of data / pilot tones 320, and one set of direct current (CC) tones 330. In various embodiments, the edge or guard tones 310 and DC 330 tones can be null. In various embodiments, the tone plane 300 includes another suitable number of pilot tones and / or includes pilot tones in other suitable tone locations.
[0080] [0080] In some respects, OFDMA tone plans can be provided for transmission using a 4x symbol duration, compared to several IEEE 802.11 protocols. For example, the 4x symbol duration can use multiple symbols that can each have a duration of 12.8 (while the symbols in some other IEEE protocols
[0081] [0081] In some respects, OFDMA tone plans can be provided for transmission using a 2x symbol duration, compared to several IEEE 802.11 protocols. For example, the 2x symbol duration can use multiple symbols that can each have a duration of 6.4 (while the symbols in some other IEEE protocols
[0082] [0082] In some respects, the data / pilot tones 320 of a transmission 300 can be divided among several different users. For example, data / pilot tones 320 can be divided between one and eight users. To split the data / pilot tones 320, an AP 104 or other device can signal to multiple devices, indicating which devices can transmit or receive which tones (of the data / pilot tones 320) in a specific transmission. Consequently, systems and methods for dividing data / pilot tones 320 may be desired, and that division may be based on a tone plane.
[0083] [0083] A tone plane can be selected based on several different characteristics. For example, it can be beneficial to have a simple tone plan, which can be compatible with most or all bandwidths. For example, an OFDMA transmission can be transmitted over 20, 40, 80, 160 or 320 MHz (or a combination thereof), and it may be desirable to use a tone plane that can be used for any of these bandwidths . Furthermore, a tone plan can be simple in that it uses a smaller number of building block sizes. For example, a tone plane can contain a unit that can be called a resource unit (RU). This unit can be used to assign a specific amount of wireless resources (for example, specific bandwidth and / or tones) to a specific user. For example, a user can be assigned a bandwidth such as several RUs, and the data / pilot tones 320 of a transmission can be divided into several RUs.
[0084] [0084] A tone plane can also be selected based on efficiency. For example, transmissions of different bandwidths (for example, 20, 40, 80, 160 or 320 MHz, or a combination of them) may have different tone numbers. Reducing the number of remaining tones can be beneficial. In addition, it can be beneficial that a tone plane is configured to preserve limits of 20, 40, 80, 160 and / or 320 MHz, when necessary. For example, it may be desirable to have a tone plane that allows each 20, 40, 80, 160 or 320 MHz portion to be decoded separately, instead of having allocations that may be on the limit between two 20, 40, 80 portions , 160 or 320 MHz different from the bandwidth. For example, it may be beneficial for the interference patterns to be aligned with 20, 40, 80, 160 or 320 MHz channels. In addition, it may be beneficial to have a channel link, which may also be known as preamble puncturing, so that when a 20 MHz transmission and a 40 MHz transmission can be transmitted, to create a 20 MHz “space” in the transmission when transmitted in 80 MHz, 160 MHz or 320 MHz. This may allow, for example, that an inherited packet be transmitted in that unused portion of the bandwidth. This puncturing can be applied to any transmission (for example, 20, 40, 80, 160 or 320 MHz, etc.) and can create "spaces" of at least 20 MHz in the transmission regardless of the channel or bandwidth being used . Finally, it may also be advantageous to use a tone plan that provides fixed pilot tone locations on several different broadcasts, such as different bandwidths.
[0085] [0085] As data transmission rate demands increase with additional devices connecting to networks or additional data for transmission over networks, larger channel bandwidths can be introduced, for example, for multiple access transmissions by orthogonal frequency division (OFDMA). In one example, tone plans for a total channel bandwidth of 320 MHz can be introduced to help increase peak system transmission data rates to use available channels more efficiently. For example, since new frequencies are available for use (for example, 6 GHz vs. 5 Ghz earlier), these new tone plans for the larger total channel bandwidths can use the newly available channels more efficiently. In addition, an increased total bandwidth that can be provided by these new tone plans can allow for better rate vs. range tradeoff. In this case, the same or similar baud rate can be used to provide greater coverage if a larger total bandwidth is used. In addition, the larger total channel bandwidths can also increase the efficiency of the tone plane (for example, for a specific BW, how many tones could be used for data transmission) and can also increase several guard bands. As with any total channel bandwidth that is used, different modes may be available depending on the availability of the channel. For example, the current 80 MHz channel bandwidths can be separated in 20 MHz, 40 MHz or 80 MHz modes.
[0086] [0086] Figure 4A is an illustration of the different 400a-400g modes available for a 240 or 320 MHz transmission. As shown in Figure 4A, 240 or 320 MHz transmissions can be transmitted in at least nine different modes as shown in 400-400g. Each of the 400a-400g modes can represent a different combination of channel bandwidth (BW) and frequency bands that can be used, depending on channel availability (for example, on 2.4, 5 and / or networks 6 GHz). In a first 400a mode, the 320 MHz transmission can be transmitted over a single 320 MHz contiguous frequency band. In a second 400b mode, the 320 MHz transmission can be transmitted over two disjoint 160 MHz frequency bands, in that each of the disjoint 160 MHz frequency bands consists of contiguous frequency bands. As shown, each of the frequency bands is separated by unused subbands (SBs). In a third 400c mode, the 320 MHz transmission can be transmitted over three disjoint frequency bands, where one of the disjoint frequency bands is a 160 MHz contiguous frequency band and the other two disjoint frequency bands are bands. contiguous frequency bands of 80 MHz.
[0087] [0087] Thus, each of the 400-400g modes can have one or more options to create the 320 MHz transmission. The 400a mode can include (1) a first option of having a single 320 MHz tone plane; (2) a second option to duplicate two 160 MHz tone planes, one in each of the two 160 MHz PHY SBs and separated by an unused SB; and (3) a third option to duplicate four 80 MHz tone planes, one in each of the four 80 MHz PHY SBs separated by unused SBs. The 400b mode can include (1) a first option to use two 160 MHz tone planes, each on a 160 MHz SB PHY and (2) a second option to duplicate four 80 MHz tone planes, one on each one of the four 80 MHz PHY SBs and separated by unused SBs.
[0088] [0088] Based on these modes and options, different tone plans can be designed or generated for the 80, 160, 240 or 320 MHz BWs. The tone plan designs for 80 MHz, 160 Mhz and 320 MHz for 3 options symbol duration are the building blocks. In some embodiments, the 240 MHz tone plan designs for 3 symbol duration options may be included in the building blocks. In some embodiments, different frequency bands may use different symbol durations. For example, for the second option of the 240 MHz frequency band, the 160 MHz frequency band can use a first symbol duration while the 80 MHz frequency band can use a second symbol duration other than the first symbol duration . In some embodiments, the tone plans for the 240 MHz bandwidth can be generated or designed based on the building blocks (for example, the 80 and 160 MHz transmissions discussed in this document).
[0089] [0089] Figure 4B is an illustration of a table of several RUs available for each of a 20 MHz channel, a 40 MHz channel, an 80 MHz channel, an 80 + 80 MHz mode or a 160 mode MHz for a 160 MHz channel and 80x4 MHz mode, 160 + 80x2 MHz mode, 160x2 MHz mode or 320 MHz mode for a 320 MHz channel. As shown in Figure 4B, each transmission can be formed from from a combination of one or more RUs of 26, 52, 106, 242, 484 or 996 tones. In general, as shown in Figure 4B, a 20 MHz channel BW can include 9 26-tone RUs, 4 52-tone RUs, 2 106-tone RUs and 1 242-tone RU. The 20 MHz channel BW may not be able to support 484 or 996 tone Rus. A 40 MHz channel BW can include 18 RUs of 26 tones, 8 RUs of 52 tones, 4 RUs of 106 tones, 2 RUs of 242 tones and 1 RU of 484 tones. The 40 MHz channel BW may not be able to support the 996-ton RU. An 80 MHz channel BW can include 37 RUs of 26 tons, 16 RUs of 52 tons, 8 RUs of 106 tons, 4 RUs of 242 tons, 2 RUs of 484 tons and 1 RU of 996 tons. The 80 MHz channel BW may not be able to support 2x996 or 4x996 tone RUs. An 80 + 80 MHz or 160 MHz channel BW can include 74 RUs of 26 tones, 32 RUs of 52 tones, 16 RUs of 106 tones, 8 RUs of 242 tones, 4 RUs of 484 tones, 2 RUs of 996 tones, and 1 RU of 2x996 tons. The 80 + 8- MHz or 160 MHz channel BW may not be able to support the 4x996 ton RU. An 80x4 MHz, 160 + 80x2 MHz, 160x2 MHz, or 320 MHz channel BW can include 148 26-tone RUs, 64 52-tone RUs, 32 106-tone RUs, 16 242-tone RUs, 8 484-tone RUs , 4 RUs of 996 tons, 2 RUs of 2x996 tons and 1 RU of 4x996 tons.
[0090] [0090] The different modes described in this document for the 240 or 320 MHz channel BW may be different options for symbol durations and pitch spacing, depending on the mode used.
[0091] [0091] Figures 5A-5B show examples of tone spacing and index ranges for different FFT sizes and symbol durations in each of the 80, 160 and 320 MHz transmissions, according to one modality. Various 802.11 protocols can use 1x symbol durations (for example, 802.1 la to 802.1 lac). 1x symbol durations can have a tone spacing of 312.5 kHz. Other 802.11 protocols can use 4x symbol lengths
[0092] [0092] Consequently, the tone index ranges for each of these options are shown in Figure 5B, which shows that 256 tones have a range of [-128, 127], 512 tones have a range of [-256, 255] , 1024 tones have a range of [-512, 511], 2048 tones have a range of [-
[0093] [0093] Figure 5C shows examples of tone planes that can be used with various FFT sizes and symbol durations in each of the 80, 160 and 320 MHz transmissions, according to a modality. As shown in Figure 5C, option 1, 1x symbol duration, can provide an 80 MHz 11ac tone plane (1x symbol duration), and alternatively, a 20 MHz 11ax tone plane (4x symbol duration) ) accelerated by 4 for the 256-tone FFT size, a 160 MHz 11ac tone plane (with 1x symbol duration), and alternatively, a 40 MHz 11ax tone plane (with 4x symbol duration) accelerated by 4 for the FFT size of 512 tones, and an 80 MHz 11ax tone plan (4x symbol duration) accelerated by 4 and, alternatively, duplicate two 160 MHz 11ac tone planes (1x symbol duration) for the size 1024 FFT. Option 2, 2x symbol duration, can provide a 160 MHz 11ac tone plane (1x symbol duration) decelerated by 2, and alternatively, a 40 MHz 11ax tone plane (symbol duration 4x) accelerated by 2 for the 512-ton FFT size, an 80 MHz 11ax tone plane (4x symbol duration) accelerated by 2 for the size 1024-ton FFT and, alternatively, a 160 MHz 11ax tone plane (4x symbol duration) accelerated by 2 and, alternatively, new 2048-point tone plane designs for FFT 2048 size. 3, 4x symbol duration, can provide an 80 MHz 11ax tone plan (4x symbol duration) for the 1024-tone FFT size, a 160 MHz 11ax tone plan (4x symbol duration), and alternatively, new 2048-point tone plan designs for the 2048-ton FFT size, and duplicate two 160 MHz 11ax tone planes (4x symbol duration), and alternatively, new 4096-point tone plan designs for FFT size 4096. Additional tone planes that may exist are not shown in Figure 5C. The 2048 point tone planes including the 11ax 160 MHz tone plan can include at least 12 left and 11 right guard tones. However, 2048 different tone planes can be generated, where the 2048 different tone planes share only at least 12 left and 11 right guard tones. For example, some 2048-point tone plans may include more than 12 left guard tones and more than 11 right ones. Consequently, the 2048-point tone plane can have a block of 2025 center tones (2048-12-11). The concept of "block of 2025 central tones" is used in this document for the sake of simplicity in representing the figure.
[0094] [0094] Options (for example, different symbol durations) can provide benefits and / or disadvantages of the various 400a-400g modes. For example, option 1 (the 1x symbol duration) may not support OFDMA (for example, 1x symbol duration tone planes
[0095] [0095] The various tone planes shown and described in relation to Figure 5C may include different settings for guard tones and direct current (CC). For example, the 80 MHz tone plane can use 6 left and 5 right guard tones and 3 CC tones in a 1x symbol duration tone plane. The 20 MHz tone planes at a 4x symbol duration can use at least 6 left and 5 right guard tones. The 40 and 80 MHz tone planes in the 4x symbol duration can use a maximum of 12 left and 11 right guard tones. The 20, 40 and 80 MHz tone planes at 4x symbol duration can use at least 3 DC tones (20 MHz tone planes) and a maximum of 5 DC tones (40 and 80 MHz tone planes) for communication of a single user (SU) and 5 or 7 DC tones for multiple user OFDMA. Therefore, the 2x symbol duration can use at least 12 left and 11 right guard tones and 5 or 7 CC tones for the 2048 and 4096 point tone planes. In some cases, tone plans for SU communication can also be used for communication without OFDMA as MIMO communication for multiple users. Overview
[0096] [0096] The 2048 point tone plane described here can be used as a 160 MHz 4x tone plane or a 320 MHz 2x tone plane. The 2048 point tone plane described in this document (for example, in in relation to Figure 5C) can use at least 12 left and 11 right guard tones and 5 CC tones for communication by a single user. Such a configuration can provide up to 2020 data and pilot tones in the 2048-point tone plane. For multi-user OFDMA, the 2048 point tone plan can be configured to use at least 12 left and 11 right guard tones and 7 CC tones, providing up to 2018 data and pilot tones in the 2048 point tone plan. The 4096-point tone plane described in this document (for example, in relation to Figure 5C) can use at least 12 left and 11 right guard tones and 5 CC tones for communication by a single user. Such a configuration can provide up to 4068 data and pilot tones in the 4096-point tone plane. For multi-user OFDMA, the 4096-point tone plane can be configured to use at least 12 left and 11 right guard tones and 7 CC tones, providing up to 4066 data and pilot tones in the 4096-point tone plane.
[0097] [0097] If a single radio frequency filter is used for 160 or 320 MHz BWs, additional guard tones can be used (for example, in addition to the 12 left or 11 right in this document) for the respective tone planes.
[0098] [0098] The 2048 point tone plan can use several configurations that provide different benefits and disadvantages. For example, in a first configuration, the 160 MHz tone plane can duplicate two 80 MHz tone planes. In such a configuration, the total 160 MHz tone plane can have an efficiency that corresponds to the 80 MHz tone planes because, due to the duplicated 80 MHz tone planes, the number of guard tones for the entire 160 MHz tone plan is doubled (that is, a set of guard tones for each 80 MHz tone plan) and subband CC tones can be wasted as they do not contain data or pilots (for example, they are not data tones or pilot tones). In this first configuration, the guard band size for the 160 MHz tone plane may be the same as the guard band size for the 80 MHz tone plane. This means that the guard band may need to be increased if the front end radio stations use a radio frequency (RF) filter designed for a larger bandwidth, for example, 160 or 320 MHz.
[0099] [0099] In a second configuration, a single user use case can use 12 left guard tones and 11 right guard tones and 5 CC tones. Such a simplistic design for the 2048-point tone plan can allocate up to 2020 filled tones (for example, data and pilot tones) for communication. In the case of using a single user, approximately 32 pilot tones (for example, 16 x 2) can leave up to 1988 tones of data for communication. The remaining tones can be CC tones or additional null tones. With 1988 data tones, the data tone factors are 1, 2, 4, 7, 14, 28, 71, 142, 284, 497, 994 and
[00100] [00100] In the second configuration, an OFDMA use case (ie multiple users) can shift all RUs in the lower half to the left (lower frequency) and shift all RUs in the upper half to the right (lower frequency) high). With this, 5 subband CC tones (essentially null tones) in the middle of each 512 point tone plane half can be eliminated, leaving only 7 CC tones in the center of the 2048 point tone plane index ( for example, [-3, 3]), instead of the original 23 CC tones in the center. For example, when the RUs were 996-tone RUs, the 996-tone RUs may have indexes of [-1012, -17], [17, 1012]). In addition to the 7 DC tones in the center of the index, 26 tones can be added to the center of the tone plane in [-16, -4] and [4, 16]. These 26 tones originate from the original 23 CC tones in the center and the 5 subband CC tones 2 times in each 512-point half tone plane minus the new 7 CC tones arranged in [-3, 3] ( 23 + 2x5-7 = 26). As described in this document, the second configuration (for example, as shown in Figure 6D in this document and further described below) can provide improved efficiencies over at least the first configuration.
[00101] [00101] In the third configuration, larger guard bands are created at the edges of the tone plane. For example, RUs can be moved to the center of the tone plane. The center of the tone plane can have 23 CC tones or null (for example, 12 + 11) that reduce CC t to y tones. The y number of CC tones can be odd and can be greater than or equal to 5 and less than or equal to 23 (that is, 5 <y <23) so that there are (23-y) / 2 more guard tones in each side of the tone plane. As described in this document, the third configuration (for example, as shown in Figure 6E in this document and further described below) can provide improved efficiencies over at least the first configuration. For example, if y = 7 CC tones, there could be (23-y) / 2 = 8 additional guard tones per side, producing 20 left guard tones and 19 right guard tones on the 2048 point tone plane.
[00102] [00102] The 4096 point tone plane described here can be used as a 320 MHz 4x tone plane. The 4096 point tone plane can use various configurations that provide different benefits and disadvantages. For example, in a first configuration (for example, as shown in Figure 6F in this document and further described below), the 320 MHz tone plane can be formed from duplicate tone planes. A first alternative of the first configuration may comprise two 160 MHz tone planes. A second alternative of the first configuration may comprise four duplicate 80 MHz tone planes (1024 point tone planes) to form the 320 MHz tone plan ( 4096 point tone plane).
[00103] [00103] In a second configuration, a single user use case can use 12 left guard tones and 11 right guard tones and 5 CC tones. Such a simplistic design for the 4096-point tone plan can allocate up to 4068 filled tones (for example, data and pilot tones) for communication. In the case of using a single user, approximately 64 pilot tones (for example, 16 x 4) can leave up to 4004 tones of data for communication. The remaining tones can be CC tones or additional null tones. With 4004 tones of data, the factors of the tones of data are 1, 2, 4, 7, 11, 13, 14, 22, 26, 28, 44, 52, 77,
[00104] [00104] In the second configuration, an OFDMA use case (ie, multiple users) can duplicate two 2048-point tone planes in each half of the 4096-point tone plan. Each half of 2048 points can have at least 5 to 7 tones that are null tones (for example, unfilled tones). At the center of the 4096-point tone plane, there are 23 unfilled tones (for example, 12 + 11 tones). All RUs in the bottom half are shifted to the left (lowest frequency) and all RUs in the top half are shifted to the right (highest frequency). With this, 5 subband CC tones in the middle of each 2048 point halftone plane can be eliminated, leaving only 7 CC tones in the center of the 4096 point tone plane index (for example, [-3 , 3]), instead of the original 23 CC tones in the center. For example, when RUs are 2020 tones RUs, 2020 tones RUs can have indexes of [-2036, -17], [17, 2036]). 26 tones (12 + 11 + 5 + 5-7 tones) can be added to the center of the tone plane in [-16, -4] and [4, 16]. As described in this document, the second configuration (for example, as shown in Figure 6G in this document and further described below) can provide improved efficiencies over at least the first 4096-point tone plane configuration.
[00105] [00105] In the third configuration of the 4096-point tone plane, larger guard bands are created at the edges of the tone plane. This third 4096-point tone plane configuration can be based on the duplication of two 160 MHz tone planes to four 80 MHz tone planes. For example, RUs can be shifted towards the center of the tone plane to reduce to z the CC tones in the center of the tone plane. The z number of CC tones can be odd and can be greater than or equal to 5 and less than or equal to 23 (that is, 5 <z <23) so that there are (23-z) / 2 more guard tones in each side of the tone plane. As described in this document, the third configuration (for example, as shown in Figure 6H in this document) can provide improved efficiencies over at least the first configuration. For example, if z = 7 CC tones, there could be (23-z) / 2 = 8 additional guard tones per side, producing at least 20 left and 19 right guard tones in the 4096-point tone plane.
[00106] [00106] The 80 MHz 4x symbol duration tone plane for 80 MHz disjoint SBs can be based on single user 80 802.11ax and / or OFDMA tone plans. The 160 Mhz tone plane of 4x symbol duration for contiguous 160 MHz SBs that are disjoint from other
[00107] [00107] A 320 MHz plane of 4x symbol duration for contiguous 320 MHz SBs can use one of several options. As a first option, two single user 160 MHz tone planes or 4x symbol duration OFDMA are duplicated on each 160 MHz SB of the 320 MHz SB. In such an option (Option 1a), four tone planes of 80 MHz of a single user or OFDMA of 4x 802.11ax symbol duration are duplicated in each 80 MHz SB of the 320 MHz SB. Alternatively (Option 1b), in such an option, two 160 MHz tone planes of a single user or OFDMA with expanded guard bands on the left and right edge can be duplicated on each 160 MHz SB from 320 MHz SB with reduced CC tones in the center of the tone plane (for example, reduced to y CC tones). As a second option, single-user or OFDMA tone plans with expanded left and right edge guard bands can be implemented. In such an option (Option 2a), four single-user 80 MHz tone planes or 4x 802.11ax symbol duration OFDMA can be duplicated on each 80 MHz SB of the 320 MHz SB with reduced DC tones in the center of the plan of tone (for example, reduced to z CC tones) or, alternatively (Option 2b), two single user 160 MHz tone plans or OFDMA with expanded guard bands on the left and right edge can be duplicated on each SB of 160 MHz of 320 MHz SB with reduced DC tones in the center of the tone plane (for example, reduced to z DC tones).
[00108] [00108] Figures 6A-6H show examples of transmissions of 20 MHz, 40 MHz, 80 MHz, 160 MHz and 320 MHz using allocations of 26, 52, 106, 242, 484, 996 tones and / or others, according to various modalities. Certain Modalities
[00109] [00109] In particular, Figure 6A shows examples of 20 MHz 600A transmissions, having 6 left edge tones, 7 CC tones and 5 right edge tones, and a total of 238 usable tones for OFDMA or 242 usable tones for a single user. Although Figure 6A shows examples of four 600A transmissions using various combinations of 26, 52, 106 and 242 tone blocks, allocations within any given transmission can include multiple tone blocks of different sizes, having different layouts, in various modalities.
[00110] [00110] Figure 6B shows examples of 40 MHz 600B transmissions, having 12 left edge tones, 5 CC tones and 11 right edge tones, and a total of 484 usable tones. Although Figure 6B shows examples of four 600B transmissions using various combinations of 26, 52, 106 and 242 tone blocks, allocations within any given transmission can include multiple tone blocks of different sizes, having different arrangements, in various modalities. In the illustrated embodiment, each 40 MHz 600B transmission is a duplicate of two 20 MHz 650B transmissions, which in various modalities may be the 20 MHz 600A transmissions of Figure 6A or any other 20 MHz transmission discussed in this document.
[00111] [00111] Figure 6C shows examples of 80 MHz 600C transmissions, having 12 left edge tones, 7 CC tones and 11 right edge tones, and a total of 994 usable tones for OFDMA and a total of 996 usable tones for the allocation of the entire bandwidth (BW) with the reduced number of DC tones being 5. Although Figure 6C shows examples of five 600C transmissions using various combinations of blocks of 26, 52, 106 and 996 tones, allocations within any given transmission can include multiple blocks of tone of different sizes, having different arrangements, in various modalities.
[00112] [00112] The fifth of the 600C illustrated transmissions includes a single user tone plan that has 5 CC tones in various modes. Consequently, the SU tone plane can include 996 usable tones.
[00113] [00113] Figure 6D shows examples of 2048 point tone plans for single user and OFDMA applications. As described in this document, the single user tone plan for the 2048 point tone plan can include the 12 left edge guard tones, 5 CC tones in the center, and a 2020 UK tone in which all 1010 shades are in each half, and the 11 right edge guard shades. The application of OFDMA can provide at least four variations for the 2048 point contiguous tone plane. In the first variation, the 2048-point tone plane includes the 12 left border or guard tones, a 996-tone, 13-tone UK (for example, a first part of a 26-tone central UK division) between the UK of 996 tones and the 7 tones of CC, 13 tones (for example, a second part of the division of central RU of 26 tones), a second RU of 996 tones, and the 11 tones of border or right guard. In the second variation, the 2048-point tone plane includes the 12 left border or guard tones, a 996-tone, 13-tone UK (for example, a first part of a 26-tone central UK division) between the UK of 996 tones and the 7 tones of CC, 13 tones (for example, a second part of the division of central RU of 26 tones), a block of 994 tones for RUs of OFDMA with 2 tones of CC, and the 11 tones of edge or has rights. In the third variation, the 2048-point tone plane includes the 12 left edge or guard tones, a 994-tone block for OFDMA RUs with 2 sub-band CC tones, 13 tones (for example, a first part of a division of central RU of 26 tones), the 7 tones of CC, 13 tones (for example, a second part of the division of central RU of 26 tones), a RU of 996 tones, and the 11 tones of right border or guard . In the fourth variation, the 2048-point tone plan includes the 12 left edge or guard tones, a block of 994 tones for OFDMA RUs with 2 additional CC tones, 13 tones (for example, a first part of a division of 26-tone central UK), the 7-tone CC, 13-tone (for example, a second part of the 26-tone central UK division), a 994-tone block for OFDMA RUs with 2 sub-band CC tones additional, and the 11 right border or guard tones.
[00114] [00114] Figure 6E shows examples of 2048 point tone planes for single user and OFDMA applications. As described in this document, the single user tone plan of the 2048 point tone plan in Figure 6E can include a larger guard band at the edges of the 2048 point tone planes compared to the 2048 tone planes in Figure 6D .
[00115] [00115] Figure 6F shows an example of a 4096-point tone plane. As described in this document, the 4096 point 320 MHz contiguous tone plane in Figure 6F can include 12 left edge guard tones, a 2025 point first center tone block, 12 + 11 CC tones in the center of the plane of tone, a second central tone block of 2025 points, and 11 right edge guard tones. The 4096-point tone plane shown can apply single user and OFDMA communication. Note that the detailed tone plan design in the 2025 point center tone block depends on the 2048 point tone plan design.
[00116] [00116] Figure 6G shows another example of a 4096 point tone plane. As described in this document, the 4096 point 320 MHz contiguous tone plane in Figure 6G can include 12 left edge guard tones, a first 2025 point center tone block with 5 unfilled middle tones removed (which becomes essentially a 2020 dot tone block), 13 tones (first half of the 26-tone central UK division), 7 CC tones in the center of the tone plane, 13 tones (second half of the 26-tone central UK division) , a second 2025-point center tone block with 5 filled middle tones removed (which essentially becomes a 2020-point tone block), and 11 right edge guard tones. The 4096-point tone plane shown can apply single-user and OFDMA communication, depending on the detailed tone plane in the 2025-point center tone block.
[00117] [00117] Figure 6H shows another example of a 4096 point tone plane. As described in this document, the 4096-point 320 MHz contiguous tone plane of Figure 6H may have expanded guard bands that may include (23.5-z) / 2 left edge guard tones, a first tone block 2025-point center tone, z CC tones in the center of the tone plane, a second 2025-point center tone block, and (22.5-z) / 2 right edge guard tones. The 4096-point tone plane shown can apply single user and OFDMA communication. Non-contiguous and fractional bandwidth
[00118] [00118] As discussed above, AP 104 can allocate one or more RUs to each STA 106A-106D. In some embodiments, such allocations may be contiguous within the bandwidth of each transmission. In other modalities, allocations may be non-contiguous. In some embodiments, one or more sub-bands (SBs) can be selected for, or determined to contain, interfering wireless transmissions. Such SBs may be called null subbands, and may contain one or more unallocated RUs.
[00119] [00119] Although several transmissions may be referred to in this document as sub-bands, the person skilled in the art will understand that, in some modalities, the sub-bands
[00120] [00120] Fractional or non-contiguous channel allocation is available on a variety of BSS BWs including 80, 160, 80 + 80 MHz, 320 MHz, 160 + 160 MHz (or 2x160 MHz), 160 + 80 + 80 MHz ( or 160 + 2x80 MHz) or 80 + 80 + 80 + 80 MHz (or 4x80 MHz). The entire PPDU BW tone plane may not be suitable in the channel bonding cases discussed above. For example, null SBs may not be aligned with the physical limits of 20 MHz and the UK limits on unmodified tone planes may result in insufficient mitigation of interference between channels.
[00121] [00121] Again with reference to Figure 6C,
[00122] [00122] As shown in Figure 6C, the first block of 242 tones 685 is shifted 2 tones from a limit 680 of a first physical SB of 20 MHz 681. The second block of 242 tones 686 includes 2 tones that cross the limit of 20 680 MHz. Consequently, in modes where the first 20 MHz 681 physical SB is a null SB and 3 additional left guard tones are specified, the 2 overlapping tones plus 3 left guard tones are equal to 5 total 691 tones, which can be called impacted tones. Such impacted tones may overlap with a null SB, or a guard band from it. Similarly, due to the fact that the second block of 242 tones 686 includes impacted tones, it can be called an impacted RU. In addition, when the second 20 MHz SB 682 is a null SB, the second entire block of 242 tones 686 can be impacted (240 overlapping tones, plus 2 right edge tones).
[00123] [00123] The 7 tones of CC can be divided into 3 + 4 tones in a limit of 20 MHz and can serve as guard bands for the limit of 20 MHz in some modalities. The third block of 242 tones 687 includes 3 tones that cross a limit of 20 MHz 690, assuming that 2 right guard tones contain a total of 5 impacted tones 692 when the fourth 20 MHz physical SB 684 is null. The fourth block of 242 tones 688 is 3 tones away from the 20 MHz 690 limit. Although the previous description refers to blocks of 242 tones 685-689, blocks of 26, 56 and 106 tones can be impacted in the same way (and different tones of the same RU can be impacted in relation to different 20 MHz PHY SBs). For example, the 106 tone block 695 (and others) can include at least 4 impacted tones 693 in relation to the first 20 MHz physical SB 681 and all tones can be impacted in relation to the second 20 MHz physical SB 682, and so on. In addition, in modalities where the number of guard tones is less or greater, more or less total tones can be impacted, respectively. Independent encoding and merge considerations
[00124] [00124] As long as multiple RUs are assigned to a user, independent coding and interleaving within each RU can be used. Alternatively, jointly encoding all information can be done before analyzing the information in different RUs using an analyzer. Consequently, independent interleaving in each UK can be used. Alternatively, joint coding and interleaving in all tones in the assigned RUs can be used. Independent PPDUs for Non-Contiguous Channels
[00125] [00125] Figure 7 shows an example of UK subcarrier indices, according to one modality. The UK subcarrier indices as shown in Figure 7 may correspond to the 160 MHz and 320 MHz tone planes of 4x symbol duration described in this document (also marked with reference to Options 1, 2, 1a, 1b, 2a and 2b ). For example, the 160 MHz tone plane described in relation to Option 1 can have RU sizes of 26, 52, 106, 242, 484 and 996 tones.
[00126] [00126] The 320 MHz tone plane described in relation to Option 1a can also have RU sizes of 26, 52, 106, 242, 484 and 996 tones. The subcarrier rates on the lowest 80 MHz SB can be reduced in 1536, while the subcarrier rates on the second lowest 80 MHz SB are reduced by 512. The subcarrier rates on the second highest 80 MHz SB can be increased in 512, while the sub-carrier rates of the highest 80 MHz SB can be increased in 1536. The 320 MHz tone plane described in relation to Option 1b can also have RU sizes of 26, 52, 106, 242, 484 and 996 tones. Subcarrier rates on the lowest 80 MHz SB can be reduced by 1524.5 + y / 2, while subcarrier rates on the second lowest 80 MHz SB are reduced by 523.5-y / 2. The subcarrier rates on the second highest 80 MHz SB can be increased by 523.5-y / 2 while the subcarrier rates on the highest 80 MHz SB can be increased by 1524.5.5 + y / 2, on that y is odd and greater than or equal to 5 and less than or equal to 23. Consequently, Option 1b may be duplicating two 160 MHz tone planes to form a 320 MHz tone plan.
[00127] [00127] The 320 MHz tone plane described in relation to Option 2a can also have RU sizes of 26, 52, 106, 242, 484 and 996 tones. Subcarrier indices in the
[00128] [00128] In some embodiments, the 4x symbol duration tone plans for the 320 MHz BW can have several minimum size RUs. For example, the minimum size RU could be 26 tones, indicating that the 4096 pt tone plane for the 320 MHz BW can include 148 RUs of 26 tones. When the minimum size RU has 52 tones, 64 RUs of 52 tones may be included in the 320 MHz BW. However, the overhead associated with such small RUs can create inefficiencies in the 320 MHz BW that outweigh the benefit provided. In some modalities, the minimum size of RU can be limited to 52 tones or 106 tones.
[00129] [00129] In some modalities, when the minimum size of RU is limited to 52 tones, the displacement of RUs to align the limits of RU within the alignment of SB PHY limits may not be performed in relation to RUs of 26 tones (for example, each 80 MHz SB). With a space of at least 26 tones, by displacing RUs, the RU limits can be aligned within the PHY subband limits (for example, 20 MHz). When all RUs are 242-tone RUs, there can be a space of 26 tones. When smaller RUs are used (for example, 106-tone RUs), more space may be available.
[00130] [00130] In some embodiments, preamble puncturing, as described in this document, can be implemented. For example, for each 20 MHz SB PHY, 3 left and 2 right guard tones can be used for adjacent channel rejection. Thus, the RUs in the first and fourth PHY SBs of 20 MHz are within the PHY limits of 20 MHz with 12 left guard tones + 2 right and 3 left + 11 right. RUs in the second 20 MHz PHY can have 2 tones entering the first 20 MHz PHY and RUs in the third 20 MHz PHY can have 3 tones entering the fourth 20 MHz PHY.
[00131] [00131] In some modalities, when the minimum RU size is 52 tones, 26 tone RUs may not be used. Consequently, the 160 MHz tone plane described in relation to Option 1 and the 320 MHz tone plane described in relation to Option 1a can be modified according to the 80 MHz SB tone plane for boundary alignment. In such a modification, the RUs, null tones, data tones and pilot tones in the first and fourth 20 MHz PHY SBs may not need to be adjusted or moved. The RUs, null tones, data tones and pilot tones in the second 20 MHz PHY can be shifted to the right by A tones, where A is greater than or equal to 5 and less than or equal to 13 (that is, subcarrier indexes + A). RUs, null tones, data tones and pilot tones in the third 20 MHz PHY can be shifted to the left by A tones, where A is greater than or equal to 5 and less than or equal to 13 (that is, subcarrier indices - A).
[00132] [00132] Figure 8A shows an example of modifying an 80 MHz SB tone plane to an 80 MHz SB tone plane 800b for boundary alignment, according to an embodiment. In the 80 MHz SB tone planes shown, the 26-tone RUs in white and the 26-tone central RU split (for example, the two 13-tone blocks on each side of the CC tones) are unused. Each of the 80 MHz SB tone planes 800a and 800b of Figure 8A is divided into four 20 MHz PHY SBs 802a-802d. As generally shown in Figure 8A, the first 20 MHz PHY SB 802a can include 256 tones in an index range of [-512, -257] that includes the 12 left edge or guard tones and the 244 adjacent tones in the RUs shown (for example, the first 242-tone UK and two-tone from the second 242-tone UK adjacent to the first 242-tone UK). The second PHY SB of 20 MHz 802b can include 256 tones in an index range of [-256, -1] that includes the remaining 240 tones of the second 242-tone UK, the first 13 unused tones adjacent to the second UK 242 tones (the first block of 13 tones can be a first part of a 26 tones UK division), and 3 tones of the 7 tones of CC. The third PHY SB of 20 MHz 802c can include 256 tones in an index range of [0, 255] that includes the remaining 4 tones of the 7 CC tones, the second 13 unused tones adjacent to the 7 CC tones ( the second block of 13 tones can be a second part of a division of RU of 26 tones), and 239 tones of the third RU of 242 tones adjacent to the second 13 unused tones. The fourth 20 MHz 802d PHY SB can include 256 tones in an index range of [256, 511] that includes the remaining 3 tones of the third 242-tone UK, the fourth entire 242-tone UK unit adjacent to the third unit of 242 tones RU, and the 11 tones of edge or guard right. As shown in Figure 8A, when the 80 MHz SB tone plane can be adjusted or modified for threshold alignment, the RUs on the first and fourth 20 MHz PHY SBs (for example, 802a and 802d) cannot move , but the RUs on the second 20 MHz 802 PHY SB may shift to the right by A tones (subcarrier indices for these RU limits, null tones and pilot tones are increased by A) and the RUs on the third PHY SB 20 MHz 802c can shift to the left by A tones (subcarrier indices for these UK limits, null tones and pilot tones are reduced by A). This can be seen by inserting A unused tones for [-258, - 259+ A] and inserting A unused tones for [259-A, 258]. As noted above, A is greater than or equal to 5 and less than or equal to 13.
[00133] [00133] After the shown limit alignment, the first 20 MHz 802 PHY SB can include the 12 left edge tones, the first 242 tone UK and 2 tones of the first unused A tones. The second PHY SB of 20 MHz 802b can include the remaining tones (A-2) of the first unused A tones, the second RU of 242 tones and at least 3 tones of the 7 CC tones (assuming A = 13, in that the zero-tone RUs do not exist). The third PHY SB of 20 MHz 802c can include the remaining 4 DC tones, the third RU of 242 tones and 10 tones of the second unused tones. The fourth 20 MHz 802d PHY SB may include the remaining 3 tones of the second A-tone UK, the fourth 242-ton UK and the 11 right edge or guard tones.
[00134] [00134] In some modalities, when the minimum RU size is 52 tones, 26 tone RUs may not be used. Figure 8B shows another example of a modified 80 MHz SB tone plane 850 for boundary alignment, according to another embodiment. Consequently, the 160 MHz tone plan described in relation to Option 2 and the 320 MHz tone plan described in relation to Options 1b, 2a and 2b can be modified according to the 80 MHz SB tone plan for alignment. limit.
[00135] [00135] The 80 MHz 850 SB tone plane of Figure 8B is divided into four 20 MHz PHY SBs 852 to 852d. In such a modification, as shown in Figure 8B, when the 80 MHz 850 SB tone plane is adjusted or modified for threshold alignment, the RUs, null tones, data tones and pilot tones in the second 20 MHz PHY 852b can be shifted to the right by A tones, where A is greater than or equal to 5 and less than or equal to 13 (that is, subcarrier indexes + A). The RUs, null tones, data tones and pilot tones on the third 20 MHz PHY 852c can be shifted to the left by A tones, where A is greater than or equal to 5 and less than or equal to 13 (that is, sub-carrier - A), similar to the modification described in relation to Figure 8A in this document. However, contrary to the modification described in relation to Figure 8A, if the first and fourth 20 MHz PHY SBs (for example, 852a and 852d) are located at the edge of the 160 or 320 MHz BW, then the first and fourth RUs 52-tone and the first 106-tone RU in the first 20 MHz PHY SB 852a move to the right by B tones, where B is greater than or equal to 0 tone and less than or equal to 26 tones, to create a band greater guard on the left edge. In such a modification, 242 tones may not be used in such a first 20 MHz PHY SB. Instead, 52 or 106 tone RUs may be used. The last two 52-tone RUs and the fourth 106-tone RUs on the fourth 20 MHz PHY SB 852d shift to the left by B tones, where B is greater than or equal to 0 tone and less than or equal to 26 tones, to create a larger guard band on the right edge. As noted above, in such a modification, 242 tones may not be used in such a fourth 20 MHz PHY SB. Instead, 52 or 106 tone RUs may be used.
[00136] [00136] Figure 9A shows an example of a proposed 320 Mhz 4x tone plane using duplicates of 2 HE 160 or duplicates of 4 HE80 tone planes, according to one modality.
[00137] [00137] Figure 9B shows an example of a proposed 320 MHz tone plan in which the minimum size of RU is limited to at least 52 tones as described in this document, according to an embodiment.
[00138] [00138] In some respects, the selected 4x tone plane can be selected independently of a hardware implementation and regardless of bandwidth mode (for example, 320 MHz vs. 4x80 MHz or 160 + 80 MHz vs. 3x80 MHz) .
[00139] [00139] Figures 10A-10D show examples of RU sub-carrier indices, according to a modality. There can be two options for 2x symbol length tone planes. For example, in the first option (2x Option 1), the 2x symbol duration tone planes can be derived from 1x 802.11ac symbol duration tone planes. For OFDMA communication, the 2x symbol tone tone planes for the ultra-high yield (UHT) 320 MHz bandwidth (eg UHT320) are formed by slowing down the very high yield tone planes (VHT) 20 / 40/80 (for example, the 802.11ac 20/40/80 tone planes), respectively, by 2 in the PHY 10/20/40 subband, depending on OFDMA allocations. In some respects, the RU sizes of 56, 114, 242, 484 (which is formed by 242x2), 968 (which is formed by 242x4) and / or 1936 (which is formed by 242x8) can be used for the planes of tone. Such tone planes can have several properties, including the least granularity of 8.75 MHz OFDMA for the 56 tone UK. In addition, the new 56 and 114 tone Rus provide greater communication efficiencies compared to the 52 and 106 tone HE RUs. However, the 968-ton RU provides less efficient communication compared to 996-ton HE RUs. Additionally, such 2x by 2x Option 2 tone planes can leverage hardware and 20 MHz PHY limit alignment for preamble puncturing. In some respects, 56-tone RUs can cause settings of 4 left guard tones + 3 right or 6 left and + 5 right to be insufficient for DL communication, which can result in disabling edge RUs. For non-OFDMA communication (for example, SU communication), all allocations are used.
[00140] [00140] Figure 10A shows tone plans for 56 tone, 114 tone and 242 tone RUs for the UHT320 (2x Option 1). The 56-tone RU tone plane is based on the VHT20 decelerated by 2 and resulting in 8.75 MHz OFDMA granularity. As shown, the 56-tone RUs are separated by 7 null tones with a 4 guard tone setting left + 3 right. Each 56-tone RU also includes a 1-tone CC subband (for example, the "56 + 1" shown). The 114-tone RU tone plane is based on the VHT40 decelerated by two and resulting in OFDMA granularity of 17.5 MHz. As shown, 114-tone RUs are separated by 11 null tones with a 6 guard tone configuration left + 5 right. Each 114-tone RU also includes a 3-tone CC sub-band (for example, the "114 + 3" shown). The 242-tone RU tone plane is based on the VHT80 decelerated by two and resulting in 37.8 MHz OFDMA granularity. As shown, the 242-tone RUs are separated by 11 null tones with a 6 guard tone configuration left + 5 right. Each 242-tone RU also includes a 3-tone CC subband (for example, the "242 + 3" shown).
[00141] [00141] In the second option (2x Option 2), the 2x symbol duration tone planes can be derived from 4x 802.11ax symbol duration tone planes.
[00142] [00142] Figure 10B shows tone plans for 26-tone, 52-tone, 106-tone and 242-tone RUs for the UHT80 (Option 2 2x). The 26-tone RU tone plane has a 4.1 MHz granularity. As shown, the 26-tone RUs are separated by various amounts of null tones (for example, 1 null tone and / or 2 null tones) with a configuration of 12 left guard tones + 11 right and a 5 tone CC. The 52-tone RU tone plane has an 8.1 MHz granularity. As shown, 52-tone RUs are separated by varying amounts of null tones (for example, 1 and / or 2 null tones) with a setting of 12 left guard tones + 11 right guard tones and a 5 tone CC. The 106-tone RU tone plane has a granularity of -16.6 MHz. As shown, 106-tone RUs are separated by 1 null tones with a configuration of 12 left guard tones + 11 right and a CC of 5 tones. The 1 null tone can separate 106-tone RUs from edge tones, 26-tone RUs, and 5-tone CC. The 242-tone RU tone plane has a granularity of -37.8 MHz. As shown, the 242-tone RUs have a configuration of 12 left guard tones + 11 right and a 5-tone CC. In such respects, the minimum frequency part of preamble puncturing for these tone planes is 20 MHz PHY. As noted in this document, since the 5th and 14th 26-tone RUs cross the 20 MHz PHY limit, these RUs can be disabled if preamble puncturing is used.
[00143] [00143] The UHT 160 tone plane and the UHT320 tone plane can be based on the HE80 and HE160 tone planes, respectively, each accelerated by 2 (Option 2A 2x). Figure 10C shows 26-tone, 52-tone, 106-tone, 242-tone, 484-tone and 996-tone RU tone plans for 2x UHT160 / 320 by HE80 / HE160 acceleration by 2 (2x Option 2A). The 26-tone RU tone plane has a granularity of -4.1 MHz. As shown, the 26-tone RUs are separated by 1 and / or 2 null tones with a configuration of 12 left guard tones + 11 right and a 7-tone CC with 13-tone RUs on each side of the 7-tone CC. The UK tone plane of

[00145] [00145] Figures 11A-11G show examples of RU sub-carrier indices, according to various modalities. These general options may exist for 1x symbol duration tone planes. For example, in the first option (Option 1 1x), 1x symbol duration tone planes can be derived from 1x 802.11ac symbol duration tone planes. For OFDMA communication, 1x symbol duration tone planes for UHT320 are formed based on the VHT20 / 40/80 tone planes (for example, the 802.11ac 20/40/80 tone planes) in the PHY 20 subband / 40/80, depending on OFDMA allocations. In some respects, the RU sizes of 56, 114, 242, 484 (which is formed by 242x2) and 968 (which is formed by 242x4) can be used for the tone planes. Such tone planes can have several properties, including the lowest granularity of 17.5 MHz OFDMA for the 56 tone UK. In addition, the new 56 and 114-tone RUs provide greater communication efficiencies compared to the 52 and 106-tone HE RUs, but the SU may have lower efficiency. In addition, such 1x tone plans per Option 1 1x can leverage hardware and 20 MHz PHY limit alignment for preamble puncturing. In some ways, the setting of 4 left guard tones + 3 right guard tones may be insufficient when 56 tone RUs were used at the edges.
[00146] [00146] Figure 11A shows tone planes.
[00147] [00147] In the second option (Option 2 2x), the 1x symbol duration tone planes can be derived from 4x 802.11ax symbol duration tone planes. Consequently, the UHT80 tone plane uses the HE20 SU / OFDMA high efficiency (HE) tone planes accelerated by 4. In some respects, the RU sizes of 26, 52, 106 and 242 can be used for the tone planes . Such tone planes can have several properties, including the lowest granularity of 8.125 MHz OFDMA for the 26 tone UK. In addition, the 52 and 106 tone RUs provide lower communication efficiencies compared to the Option 1 1x 56 and 114 tone RUs. In addition, such 1x tone plans by Option 2 1x can leverage the hardware although they are not conducive to preamble puncturing with 20 MHz PHY frequency parts. For example, the 3rd 26-tone RU and the 2nd 52-RU tones can cross the PHY limit of 20 MHz together with the 7th RU of 26 tones and the 3rd RU of 52 tones.
[00148] [00148] Figure 11B shows tone plans for 26-tone, 52-tone, 106-tone and 242-tone RUs for the UHT80 1x derived from HE20 accelerated by 4 (Option 2 1x). The 26-tone RU tone plane has an 8.1 MHz granularity. As shown, the 26-tone RUs have a configuration of 6 left guard tones + 5 right with a 7-tone CC and 13-tone RUs in each side of the 7-tone CC. 1 null tone separates the 1st RU of 26 tones from the left edge, the 2nd RU of 26 tones from the 3rd RU of 26 tones, the 6th RU of 26 tones from the 7th RU of 26 tones and the 9th RU of 26 tones from the right edge. The 52-tone RU tone plane has a granularity of -16.3 MHz. As shown, 52-tone RUs have a configuration of 6 left guard tones + 5 rights and a 7-tone CC and 13-tone RUs on each side of the 7-tone CC. 1 null tone separates the 1st 52-tone RU from the left edge, the 1st 52-tone RU from the 2nd 52-tone UK, the 3rd 52-tone UK from the 4th 52-tone UK and the 4th 26-tone UK from the right edge. The 106-tone RU tone plane has a granularity of -33.1 MHz. As shown, 106-tone RUs have a configuration of 6 left guard tones + 5 right and a 7-tone CC and 13-tone RUs on each side of the 7-tone CC. As shown, the 242-tone RU has a configuration of 6 left guard tones + 5 right guard tones. Each 242-tone RU also includes a 3-tone CC subband (for example, the "242 + 3" shown).
[00149] [00149] UHT160 and UHT320 tone planes can use duplications of 2/4 UHT80 tone planes, respectively (Option 2A 1x). Figure 11C shows 26-tone, 52-tone, 106-tone and 242-tone RU tone plans for UHT160 1x using duplicates of two UHT80 tone planes (Option 2A 1x). The 26-tone RU tone plane has a granularity of -8.1 MHz. As shown, the 26-tone RUs have a configuration of 6 left guard tones + 5 right with an 11 tone CC and 1 null tone in each side of the 11-tone CC. 1 null tone separates the 1st RU of 26 tones from the left edge, the 2nd RU of 26 tones from the 3rd RU of 26 tones, the 6th RU of 26 tones from the 7th RU of 26 tones and the 10th RU of 26 tones from the 11th RU of 26 tones, the 14th RU of 26 tones from the 15th RU of 26 tones and the 16th RU of 26 tones from the right edge. 7 null tones are connected by RUs of 13 tones on each side separating the 4th RU of 26 tones from the 5th RU of 26 tones and the 12th RU of 26 tones from the 13th RU of 26 tones. The 52-tone RU tone plane has a granularity of -16.3 MHz. As shown, 52-tone RUs have a configuration of 6 left guard + 5 right guard tones with an 11 tone CC and 1 null tone in each side of the 11-tone CC. 1 null tone separates the 1st 52-tone UK from the left edge, the 1st 52-tone UK from the 2nd 52-tone UK, the 3rd 52-tone UK from the 4th 52-tone UK, the 5th 52-tone UK from the 6th UK 52 tones, and the 7th 52-ton UK from the 8th 52-ton UK. 7 null tones connected by 13 tone RUs on each side separate the 2nd 52 tone RU from the 3rd 52 tone RU and the 6th 52 tone RU from the 7th 52 tone RU. The 106-tone RU tone plane has a granularity of -33.1 MHz. As shown, 106-tone RUs have a configuration of 6 left guard tones + 5 right and an 11 tone CC. 7 null tones connected by 13-tone RUs on each side separate the 1st 106-tone RU from the 2nd 106-tone RU and the 3rd 106-tone RU from the 4th 102-tone RU. The 242-tone UK tone plane has a granularity of 75.6 MHz. As shown, the 242-tone UK has a configuration of 6 left guard + 5 right guard tones and an 11-tone CC. As discussed, Option 2A 1x is not conducive to preamble puncturing when 20 MHz PHY parts are used. Each 242-tone RU also includes a 3-tone CC subband (for example, the "242 + 3" shown).
[00150] [00150] Alternatively, the UHT160 and UHT320 tone planes can use HE40 and HT80 tone planes accelerated by 4, respectively (Option 2B 1x). Figure 11D shows 26-tone, 52-tone, 106-tone and 242-tone RU tone plans for UHT160 1x based on HE40 accelerated by 4 tone planes (Option 2B 1x). The 26-tone RU tone plane has a granularity of -8.1 MHz. As shown, the 26-tone RUs have a configuration of 12 left guard tones + 11 right with a 5-tone CC and 1 null tone in each side of the 5-tone CC. 1 and / or 2 null tones separate the 26 tone RUs from each other and from the edges. The 52-tone RU tone plane has a granularity of - 16.3 MHz. As shown, 52-tone RUs have a configuration of 12 left guard tones + 11 right with a 5-tone CC and 1 null tone in each side of the 5-tone CC. 1 and / or 2 null tones separate the 52 tone RUs from each other and from the edges. The 106-tone RU tone plane has a -33.1 MHz granularity. As shown, 106-tone RUs have a configuration of 12 left guard tones + 11 right and a 5 tone CC with 1 null tone in each side of the 5-tone CC. 1 and / or 2 null tones separate the 106 tone RUs from each other and from the edges. The 242-tone UK tone plane has a granularity of 75.6 MHz. As shown, the 242-tone UK has a configuration of 12 left guard tones + 11 right and a 5-tone CC. As discussed, Option 2A 1x is not conducive to preamble puncturing when 20 MHz PHY parts are used. For example, with parts of PHY of 20 MHz, several tones of the tone plane cross the 20 MHz limits, including the 2nd RU of 26 tones, the 1st RU of 52 tones, the 5th RU of 26 tones, the 7th RU of 26 tones, the 3rd RU of 52 tones, the 12th RU of 26 tones, the 6th RU of 52 tones and the 14th RU of 26 tones. Each of these RUs can have different numbers of tones that cross the respective 20 MHz limits. The 17th 26-tone RU and the 8th 52-tone RU may not have enough guard bands with 20 MHz PHY parts.
[00151] [00151] Figure 11E shows RU tone plans of 26 tones, 52 tones, 106 tones, 242 tones and 996 tones for the UHT320 1x tone plan based on the duplication of four HE80 tone planes (Option 2A 1x). As shown, the 26-tone RUs have a configuration of 6 left guard + 5 right guard tones with an 11-tone CC and 1 null tone on each side of the 11-tone CC. 1 and / or 7 null tones can separate the 26 tone RUs from each other and from the edges. As shown, 52-tone RUs have a configuration of 6 left guard + 5 right guard tones with an 11-tone CC and 1 null tone on each side of the 11-tone CC. 1 and / or 7 null tones can separate the 52 tone RUs from each other and from the edges. As shown, 106-tone RUs have a configuration of 6 left guard + 5 right guard tones and an 11-tone CC with 1 null tone on each side of the 11-tone CC. RUs of varying sizes or null tones can separate 106 TU RUs from each other and from the edges. As shown, the 242-tone RU has a configuration of 6 left guard + 5 right guard tones and an 11-tone CC. Each 242-tone RU also includes a 3-tone subband CC (for example, the "242 + 3" shown). As shown, the 996-tone RU has a configuration of 12 left guard tones + 11 right guard tones. Each 996-tone RU also includes a 5-tone CC subband (for example, the "996 + 5" shown). As discussed, Option 2A 1x is not conducive to preamble puncturing when 20 MHz PHY parts are used.
[00152] [00152] Figure 11F shows tone plans for 26-tone, 52-tone, 106-tone, 242-tone, 482-tone and 996-tone RUs for HE UHT32 1x based on 4 tone planes (Option 2B 1x). As shown, the 26-tone RUs have a configuration of 12 left + 11 right guard tones with a 7-tone CC and 13-tone RUs on each side of the 7-tone CC. RUs of varying sizes separate the 26-tone RUs from each other and from the edges. As shown, 52-tone RUs have a configuration of 12 left guard + 11 right guard tones with a 7-tone CC and 13-tone RUs on each side of the 7-tone CC. RUs of varying sizes separate the 52-tone RUs from each other and from the edges. As shown, 106-tone RUs have a configuration of 12 left + 11 right guard tones and a 7-tone CC with 13-tone RUs on each side of the 7-tone CC. RUs of varying sizes separate 106-tone RUs from each other and from the edges. As shown, the 242-tone RU has a configuration of 12 left guard tones + 11 right and a 7-tone CC with 13-tone RUs on each side of the 7-tone CC. As shown, the 484-tone RU has a configuration of 12 left guard tones + 11 right and a 7-tone CC with 13-tone RUs on each side of the 7-tone CC. As shown, the 996-tone RU has a configuration of 12 left guard tones + 11 right guard tones. Each 996-tone RU also includes a 5-tone CC subband (for example, the "996 + 5" shown). As discussed, Option 2B 1x is not conducive to preamble puncturing when parts of 20 MHz PHY are used. The 1x symbol duration tone plane shown also cannot be favorable to preamble puncturing when 40 MHz PHY parts are used. For example, several RUs may have different numbers of tones that cross their respective 20 MHz or 40 MHz limits. And certain other RUs may not have enough guard bands with 20 MHz or 40 MHz PHY parts.
[00153] [00153] In the third option (Option 3 1x), the 1x symbol duration tone planes can be modified from 4x 11ax tone planes. UHT40 is duplicated from 2 UHT20 tone planes. UHT80 is duplicated from 2 UHT40 tone planes. UHT160 is duplicated from 2 UHT80 tone planes. UHT320 is duplicated from 2 UHT160 tone planes. In some respects, the RU sizes of 26, 52, 106, 242, 484 (which is formed by 242x2) and 968 (which is formed by 242x4) can be used for the tone planes. Such tone planes can have several properties. For example, 52- and 106-ton RUs provide lower communication efficiencies compared to 56 and 114-tone RUs in Option 1 1x, but SU has greater efficiencies. The least granularity of OFDMA is 8.125 MHz for the 26-tone UK. In addition, the tone planes may also be able to use preamble puncturing in parts of 20 MHz and pilot tone locations cannot be aligned.
[00154] [00154] Figure 11G shows tone plans for 26-tone, 52-tone, 106-tone, 242-tone and 996-tone RUs for 1x Option 3. As shown, 26-tone RUs have a 6-left guard tone setting + 5 rights. RUs of varying sizes separate the 26-tone RUs from each other and from the edges with 11 spaced null tones. As shown, 52-tone RUs have a configuration of 6 left guard + 5 right guard tones with an 11 tone CC. 11 null tones are spaced between 52 tone RUs. Each 52-tone RU also includes a 1-tone CC subband (for example, the "52 + 1" shown). As shown, 106 tone RUs have a configuration of 10 left guard tones + 9 right and a 19 tone CC. 19 null tones are spaced between 106 tone RUs. Each 106-tone RU also includes a 3-tone CC subband (for example, the "106 + 3" shown). As shown, 242-tone RUs have a configuration of 6 left guard + 5 right guard tones and an 11-tone CC. 11 null tones are spaced between the 242 tones RUs. Each 242-tone RU also includes a 3-tone CC subband (for example, the "242 + 3" shown). As shown, the 996-tone RU has a configuration of 12 left guard tones + 11 right guard tones.
[00155] [00155] Figure 12 shows examples of tone planes that can be used with various FFT sizes and symbol durations in each of the 80, 160 and 320 MHz subband transmissions, according to a modality. As shown in Figure 12, the 1x symbol duration will have different tone plane designs based on VHT or HE. Similarly, the 2x symbol duration has different tone plane designs based on VHT or HE.
[00156] [00156] In some respects, the 80 MHz tone plane based on 1x VHT can be based on VHT80 tone plans or recently derived from VHT20 / 40/80 tone plans. In some respects, the 160 MHz tone plan based on 1x VHT can be based on VHT 160 tone plans or recently derived from VHT20 / 40/80 tone plans. In some respects, the 320 MHz tone plan based on 1x VHT can be formed by VHT20 / 40/80 on PHY 20/40/80, depending on OFDMA allocations.
[00157] [00157] In some respects, the 80 MHz tone plane based on 1x HE can use a HE20 tone plane accelerated by 4 or can be modified based on a HE20 tone plane accelerated by 4. In some aspects, the plane 160 MHz tone based on 1x HE can duplicate two HE20 tone planes accelerated by 4, use a HE40 tone plan accelerated by 4, or can be modified based on the HE40 tone plan accelerated by 4. In some respects, the 320 MHz tone plane based on 1x HE can duplicate four HE20 tone planes accelerated by 4, can use a HE80 tone plane accelerated by 4, or can be modified based on the HE80 tone plane accelerated by 4.
[00158] [00158] In some respects, the 80 MHz 4x tone plane may use a HE80 tone plane. In some respects, the 160 MHz 4x tone plane can use a HE160 tone plane or can modify the HE160 tone plane. In some respects, the 160 MHz 4x tone plane can duplicate two HE160 tone planes or can modify the HE 160 tone planes.
[00159] [00159] In some respects, the 80 MHz tone plane based on 2x VHT can use the VHT160 tone planes decelerated by 2 or can use a new tone plane derived from VHT40 / 80 tone planes. In some respects, the 160 MHz tone plan based on 2x VHT can duplicate two VHT 160 tone planes decelerated by 2 or recently derive the VHT40 / 80 tone plan. In some respects, the 320 MHz tone plane based on 2x VHT can duplicate four tone planes 160 decelerated by 2 or the tone planes by VHT20 / 40/80 decelerated by 2 in PHY10 / 20/40, depending on allocations of OFDMA.
[00160] [00160] In some respects, the 80 MHz tone plane based on 2x HE can use a HE40 tone plane accelerated by 2 or can derive the tone plane from VHT40 / 80. In some respects, the 160 MHz tone plan based on 2x HE can use HE80 accelerated by 2 or can duplicate two HE40 tone planes accelerated by 2. In some aspects, the 320 MHz tone plan based on 2x HE can use HE160 accelerated by 2 or can duplicate four HE40 tone planes accelerated by 2.
[00161] [00161] In some respects, the UHT80 / 160/320 tone planes can be used for the sub-bands of
[00162] [00162] Figure 13A shows examples of tone planes that can be used for a 1x symbol duration tone plan design with various FFT sizes, according to one modality. As shown in Figure 13A, the 1x symbol duration will have different tone plane designs based on VHT or HE. Figure 13B shows examples of tone planes that can be used for a 2x symbol length tone plan design with various sizes of FFT, according to one embodiment. As shown in Figure 13B, the 2x symbol duration will have different tone plane designs based on VHT or HE.
