Technical Field

[0002] This application relates to the field of wireless technology, and more particularly to a communication method and apparatus. Background Technology

[0003] Wireless local area networks (WLANs) have evolved through several generations of standards, including 802.11a / b / g, 802.11n, 802.11ac, 802.11ax, 802.11be, and 802.11bn. Among these, 802.11n is known as high throughput (HT), 802.11ac as very high throughput (VHT), 802.11ax as high efficient (HE), 802.11be as extremely high throughput (EHT), and 802.11bn as ultra-high reliability (UHR).

[0004] Currently, a low-power indoor (LPI) communication method is defined, with strict limitations on the maximum transmitted power and maximum power spectral density. For example, for an access point (AP), the maximum power can be 36 dBm, and the maximum power spectral density can be 5 dBm / MHz. For a station (STA), the maximum power can be 24 dBm, and the maximum power spectral density can be -1 dBm / MHz. The device's transmit power is limited by both the maximum power and the maximum power spectral density. First, the transmit power cannot exceed the maximum power, and second, the transmit power spectral density cannot exceed the maximum power spectral density. Compared to the maximum power, the limitation on the maximum power spectral density is more stringent; the maximum transmit power is usually more heavily constrained by the maximum power spectral density. For a station, the maximum power limit stipulated by regulations is only reached when the bandwidth is at its maximum of 320 MHz. Below this bandwidth, due to the limitation on the maximum power spectral density, signals can only be transmitted at lower power. Since the power spectral density is limited, the transmission power can be improved by discretizing a finite number of subcarriers onto a wider bandwidth, i.e., more subcarriers. This is called a Discrete Resource Unit (DRU) or Distributed RU.

[0005] Therefore, how to design the subcarrier planning for DRU urgently needs to be addressed. Summary of the Invention

[0006] This application provides a communication method and apparatus that can effectively improve the transmission power of each subcarrier.

[0007] In a first aspect, embodiments of this application provide a communication method, the method being applied to a first device. The method includes:

[0008] Generate some or all fields of a Physical Layer Protocol Data Unit (PPDU); transmit some or all fields of the PPDU on a Distributed Resource Unit (DRU); the DRU is one of the subcarrier plans corresponding to a 60MHz distributed bandwidth (DBW), the 60MHz corresponding subcarrier plan (toneplan) (or subcarrier distribution) includes 12 52-tone DRUs, the index difference between two adjacent subcarriers in the 52-tone DRU is an integer multiple of 13, and the subcarrier indices of any two 52-tone DRUs in the 12 52-tone DRUs satisfy a translation relationship.

[0009] In a 52-tone DRU, the index difference between two adjacent subcarriers is 13, 26, or 39, etc. For example, the index difference between two adjacent subcarriers in a 52-tone DRU is always 13. Another example is a 52-tone DRU where the index difference between two adjacent subcarriers in the first part is 13, while the index difference between two adjacent subcarriers in the second part is 26 or 39. Yet another example is a 52-tone DRU where the index difference between two adjacent subcarriers in the first part is 13, the index difference between two adjacent subcarriers in the second part is 26, and the index difference between two adjacent subcarriers in the third part is 39.

[0010] For two 52-tone DRUs that satisfy the translation relationship, the index of the subcarriers after all subcarriers of one 52-tone DRU are the same as the index of the subcarriers of the other 52-tone DRU.

[0011] In this embodiment, the index difference between two adjacent subcarriers in the 52-tone DRU is an integer multiple of 13. This not only ensures that there is only one subcarrier within each 1MHz, increasing the transmit power of each subcarrier and achieving maximum power gain, but also, when the index difference between two adjacent subcarriers is an integer multiple of 13, their corresponding peak-to-average power ratio (PAPR) is equivalent to the PAPR corresponding to the data after 13 times downsampling. The shorter the data, the lower the average PAPR, thus effectively reducing PAPR. Furthermore, the subcarrier indices of any two 52-tone DRUs satisfy a shift relationship. For different 52-tone DRUs, the second device can use the same frequency domain channel smoothing, effectively reducing the complexity of smoothing processing and implementation.

[0012] Secondly, embodiments of this application provide a communication method applied to a second device. The method includes:

[0013] Receive some or all fields of the PPDU on the DRU; parse some or all fields of the PPDU; the DRU is one of the subcarrier plans corresponding to a discrete bandwidth of 60MHz. The subcarrier plan corresponding to 60MHz includes 12 52-tone DRUs. The index difference between two adjacent subcarriers in the 52-tone DRU is 13. The subcarrier indices of any two 52-tone DRUs in the 12 52-tone DRUs satisfy a translation relationship.

[0014] For an explanation of the second aspect, please refer to the first aspect; it will not be elaborated upon here.

[0015] In conjunction with the first or second aspect, in one possible implementation, the index difference between two adjacent subcarriers in a 52-tone DRU with an index less than 0 is 13, and the index difference between two adjacent subcarriers in a 52-tone DRU with an index greater than 0 is 13.

[0016] This effectively discretizes each subcarrier in the 52-tone DRU, making the subcarrier distribution as uniform as possible and effectively reducing PAPR.

[0017] In one possible implementation, combining the first or second aspect, the discrete bandwidth of 60MHz is the 60MHz of 80MHz that is not punched.

[0018] As an example, the highest 20MHz frequency in the 80MHz range is punched with a hole. That is, the fourth 20MHz in the 80MHz range is punched with a hole, in ascending order of frequency. As another example, the lowest 20MHz frequency in the 80MHz range is punched with a hole. That is, the first 20MHz in the 80MHz range is punched with a hole, in ascending order of frequency.

[0019] In conjunction with the first or second aspect, in one possible implementation, the index of the 60MHz subcarrier is [-500:-3, 3:253].

[0020] Combining the first or second aspect, in one possible implementation, the difference between the maximum index of the negative half-frequency and the minimum index of the positive half-frequency in a 52-tone DRU is 39. Alternatively, the index difference between two adjacent subcarriers on either side of the DC subcarrier in a 52-tone DRU is 39.

[0021] Therefore, the two subcarriers mentioned above are kept as far away as possible from the subcarrier with index 0, so as to reserve sufficient protection interval for the DC subcarrier.

[0022] In conjunction with the first or second aspect, in one possible implementation, the 12 52-tone DRUs are 52-tone DRU 1, 52-tone DRU 2, 52-tone DRU 3, 52-tone DRU 4, 52-tone DRU 5, 52-tone DRU 6, 52-tone DRU 7, 52-tone DRU 8, 52-tone DRU 9, 52-tone DRU 10, 52-tone DRU 11, and 52-tone DRU 12;

[0023] The shift value between 52-tone DRU 1 and 52-tone DRU 2 is 7;

[0024] The shift value between 52-tone DRU 3 and 52-tone DRU 4 is 7;

[0025] The shift value between 52-tone DRU 5 and 52-tone DRU 6 is 7;

[0026] The shift value between 52-tone DRU 7 and 52-tone DRU 8 is 7;

[0027] The shift value between 52-tone DRU 9 and 52-tone DRU 10 is 7;

[0028] The shift value between 52-tone DRU 11 and 52-tone DRU 12 is 7;

[0029] or,

[0030] The shift value between 52-tone DRU 1 and 52-tone DRU 2 is 6;

[0031] The shift value between 52-tone DRU 3 and 52-tone DRU 4 is 6;

[0032] The shift value between 52-tone DRU 5 and 52-tone DRU 6 is 6;

[0033] The shift value between 52-tone DRU 7 and 52-tone DRU 8 is 6;

[0034] The shift value between 52-tone DRU 9 and 52-tone DRU 10 is 6;

[0035] The shift value between 52-tone DRU 11 and 52-tone DRU 12 is 6.

[0036] Alternatively, the index difference between the nth subcarrier in 52-tone DRU i and the nth subcarrier in 52-tone DRU i+1 is 7 or 6, where i = 1, 3, 5, 7, 9, 11, and n = 1, 2, 3, ..., 52. For example, the index obtained by shifting all subcarriers in 52-tone DRU 1 7 subcarriers to the right is the same as the index of the subcarriers in 52-tone DRU 2. Or, the index difference between the nth subcarrier in 52-tone DRU 1 and the nth subcarrier in 52-tone DRU 2 is 7.

[0037] In conjunction with the first or second aspect, in one possible implementation, one of the twelve 52-tone DRUs corresponds to one of the twelve subcarrier groups, and any two 52-tone DRUs correspond to different subcarrier groups. The twelve subcarrier groups are twelve of the following thirteen subcarrier groups:

[0038] [-494:13:-13,13:13:247];

[0039] [-493:13:-12,14:13:248];

[0040] [-492:13:-11,15:13:249];

[0041] [-491:13:-10,3:13:250];

[0042] [-490:13:-9,4:13:251];

[0043] [-489:13:-8,5:13:252];

[0044] [-488:13:-7,6:13:253];

[0045] [-500:13:-6,7:13:241];

[0046] [-499:13:-5,8:13:242];

[0047] [-498:13:-4,9:13:243];

[0048] [-497:13:-3,10:13:244];

[0049] [-496:13:-15,11:13:245];

[0050] [-495:13:-14,12:13:246].

[0051] One 52-tone DRU corresponds to one subcarrier group, meaning that the subcarrier indices of this 52-tone DRU are contained within this subcarrier group. The number of subcarriers in a 52-tone DRU is less than the number of subcarriers in a subcarrier group. Each of the 12 52-tone DRUs corresponds to one subcarrier group.

[0052] In this embodiment, the index difference between two adjacent subcarriers in each subcarrier group is 13, and 60MHz is divided into 13 subcarrier groups. This not only ensures that all subcarriers are distributed as evenly as possible, but also ensures that the 52-toneDRU has only one subcarrier in each 1MHz, thereby improving the transmission power and power gain of each subcarrier.

[0053] In conjunction with the first or second aspect, in one possible implementation, the subcarrier planning corresponding to 60MHz also includes 6 106-tone DRUs;

[0054] The subcarriers of 106-tone DRU 1 include the subcarriers of 52-tone DRU 1 and 52-tone DRU 2;

[0055] The subcarriers of 106-tone DRU 2 include the subcarriers of 52-tone DRU 3 and 52-tone DRU 4;

[0056] The subcarriers of 106-tone DRU 3 include the subcarriers of 52-tone DRU 5 and 52-tone DRU 6;

[0057] The subcarriers of 106-tone DRU 4 include the subcarriers of 52-tone DRU 7 and 52-tone DRU 8;

[0058] The subcarriers of 106-tone DRU 5 include the subcarriers of 52-tone DRU 9 and 52-tone DRU 10;

[0059] The subcarriers of 106-tone DRU 6 include the subcarriers of 52-tone DRU 11 and 52-tone DRU 12.

[0060] In this embodiment, a subcarrier of a 106-tone DRU includes two subcarriers of a 52-tone DRU, which effectively simplifies resource allocation instructions.

[0061] In combination with the first or second aspect, in one possible implementation, the subcarrier indices of any two of the six 106-tone DRUs satisfy a translation relationship.

[0062] In conjunction with the first or second aspect, in one possible implementation, the subcarriers of the 106-tone DRU include two 52-tone DRU subcarriers corresponding to a shift value of 7; or, the subcarriers of the 106-tone DRU include two 52-tone DRU subcarriers corresponding to a shift value of 6.

[0063] Therefore, the subcarrier indices of any two 106-tone DRUs satisfy a translation relationship. For different 106-tone DRUs, the second device can reuse the same module for frequency domain smoothing, reducing implementation complexity.

[0064] In conjunction with the first or second aspect, in one possible implementation, the subcarrier planning corresponding to 60MHz also includes three 242-tone DRUs;

[0065] The subcarriers of 242-tone DRU 1 include the subcarriers of 106-tone DRU 1 and 106-tone DRU 2;

[0066] The subcarriers of 242-tone DRU 2 include the subcarriers of 106-tone DRU 3 and 106-tone DRU 4;

[0067] The subcarriers of 242-tone DRU 3 include the subcarriers of 106-tone DRU 5 and 106-tone DRU 6.

[0068] In this embodiment, a subcarrier of a 106-tone DRU includes two subcarriers of a 52-tone DRU, which effectively simplifies resource allocation instructions.

[0069] In one possible implementation, combining the first or second aspect,

[0070] The subcarriers of 242-tone DRU 1 also include some subcarriers in the four subcarrier groups corresponding to 106-tone DRU 1 and 106-tone DRU 2, as well as some subcarriers in one subcarrier group other than the 12 subcarrier groups out of the 13 subcarrier groups;

[0071] The subcarriers of 242-tone DRU 2 also include some subcarriers in the four subcarrier groups corresponding to 106-tone DRU 3 and 106-tone DRU 4, as well as some subcarriers in one subcarrier group other than 12 subcarrier groups out of the 13 subcarrier groups;

[0072] The subcarriers of 242-tone DRU 3 also include some subcarriers from the four subcarrier groups corresponding to 106-tone DRU 5 and 106-tone DRU 6, as well as some subcarriers from one of the 13 subcarrier groups excluding the 12 subcarrier groups.

[0073] The subcarrier indices of the 52-tone DRU, the 106-tone DRU, and the 242-tone DRU mentioned in the first or second aspect are referred to in specific embodiments and will not be repeated here.

[0635] To facilitate understanding of the technical solution of this application, the application will be further described below with reference to the accompanying drawings.

[0636] The terms "first" and "second," etc., used in the specification, claims, and drawings of this application are used only to distinguish different objects and not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0637] The term "embodiment" as used herein means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0638] In this application, "at least one (item)" refers to one or more, "more than one" refers to two or more, "at least two (items)" refers to two or three or more, and "and / or" is used to describe the relationship between related objects, indicating that there can be three relationships. For example, "A and / or B" can mean: only A exists, only B exists, and both A and B exist simultaneously, where A and B can be singular or plural. "Or" indicates that there can be two relationships, such as only A exists and only B exists; when A and B are not mutually exclusive, it can also mean that there are three relationships, such as only A exists, only B exists, and both A and B exist simultaneously. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one (item) of the following" or similar expressions refer to any combination of these items. For example, at least one (item) of a, b, or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c".

[0639] In this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which can include direct transmission via the air interface or indirect transmission via the air interface from other units or modules. "Receive information from YY" can be understood as the source of the information being YY, which can include direct reception from YY via the air interface or indirect reception from YY via the air interface from other units or modules. "Send" can also be understood as the "output" of a chip interface, and "receive" can also be understood as the "input" of a chip interface. In other words, sending and receiving can occur between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via buses, traces, or interfaces.

[0640] In this application, the dashed lines in the accompanying drawings indicate that they are optional.

[0641] The following describes the communication system involved in this application.

[0642] The technical solutions provided in this application can be applied to wireless local area network (WLAN) systems, such as Wi-Fi. For example, the methods provided in this application can be applied to the IEEE 802.11 series protocols, such as 802.11a / b / g, 802.11bf, 802.11az, 802.11bk, 802.11n, 802.11ac, 802.11ax, 802.11be, 802.11bn, or next-generation protocols, and even more specifically, 802.11ad, 802.11ay, 802.11bq, or next-generation protocols, etc., which will not be listed here. The technical solutions provided in this application can also be applied to wireless personal area networks (WPANs) based on ultra-wideband (UWB) technology. The technical solutions provided in this application can also be applied to millimeter wave (MMW) technology, including integrated millimeter wave (IMMW). For example, the methods provided in this application can be applied to IEEE 802.15 series protocols, such as 802.15.4a, 802.15.4z, or 802.15.4ab, or a future generation of UWB WPAN protocol, or StarFlash, etc., and will not be listed exhaustively. The technical solutions provided in this application can also be applied to the following communication systems, such as Internet of Things (IoT) systems, vehicle-to-everything (V2X) systems, narrowband Internet of Things (NB-IoT) systems, long term evolution (LTE) systems, 5th generation (5G) communication systems, and new communication systems emerging in future communication development.

[0643] WLAN systems can provide high-speed, low-latency transmission. As WLAN application scenarios continue to evolve, WLAN systems will be applied to more scenarios or industries, such as the Internet of Things industry, the Internet of Vehicles industry, the banking industry, enterprise offices, stadiums and exhibition halls, concert halls, hotel rooms, dormitories, hospital wards, classrooms, shopping malls, squares, streets, production workshops and warehouses, etc. Of course, devices that support WLAN communication or sensing (such as access points or sites) can be sensor nodes in smart cities (such as smart water meters, smart electricity meters, and smart air monitoring nodes), smart devices in smart homes (such as smart cameras, projectors, displays, televisions, speakers, refrigerators, and washing machines), nodes in the Internet of Things (IoT), entertainment terminals (such as wearable devices for augmented reality (AR) and virtual reality (VR), smart devices in smart offices (such as printers, projectors, loudspeakers, and speakers), vehicle-to-everything (V2X) devices, infrastructure in daily life scenarios (such as vending machines, self-service navigation kiosks in supermarkets, self-service checkout machines, and self-service ordering machines), and equipment in large sports and music venues.

[0644] Although the embodiments of this application primarily use WLAN as an example, especially networks applied to the IEEE 802.11 series of standards, the various aspects involved in the embodiments of this application can be extended to other networks employing various standards or protocols. For example, Bluetooth, high-performance radio LAN (HIPERLAN) (a wireless standard similar to the IEEE 802.11 standard, mainly used in Europe), and wide area networks (WANs) or other networks now known or to be developed in the future.

[0645] In one possible implementation, the method provided in this application embodiment can be implemented by a communication device in a communication system. That is, the communication device is used to implement the method provided in this application embodiment. The communication device includes a first device or a second device. This application embodiment describes the method provided in this application embodiment using a first device and a second device. However, during the transmission of the PPDU, the first device and the second device can also forward the PPDU through other devices, such as forwarding the PPDU between the first device and the second device through a forwarding device. This application embodiment does not limit the use of other devices besides the first device and the second device.

[0646] As an example, the first device is an access point (AP), and the second device is a non-access point station (non-AP STA). Alternatively, the first device is a non-AP STA, and the second device is an AP. As another example, the first device is a management node (G node), and the second device is a terminal (T) node. G nodes and T nodes are nodes involved in the StarScan standard. For example, a T node can be a barcode scanner, radio frequency identification (RFID), a sensor, a global positioning system (GPS), LiDAR, a battery cell, a mobile phone with positioning capabilities, a wearable device, a personal digital assistant (PDA), a positioning card, or a positioning terminal, etc. Alternatively, the first device is a T node, and the second device is a G node. As yet another example, the first device is a network device, and the second device is a terminal device. Alternatively, the first device is a terminal device, and the second device is a network device. The specific types of the first and second devices are not listed here.

[0647] An access point is a device with wireless communication capabilities, supporting communication or sensing using WLAN protocols. It has the function of communicating or sensing with other devices in the WLAN network (such as non-AP STAs or other access points), and can also have the function of communicating or sensing with other devices. Alternatively, an access point acts as a bridge connecting wired and wireless networks, its main function being to connect various wireless network clients together and then connect the wireless network to the Ethernet. In a WLAN system, an access point can be called an Access Point Station (AP STA). This wireless communication device can be a complete device, or it can be a chip, processing system, or functional module installed in a complete device. The device with these chips, processing systems, or functional modules can implement the methods and functions of the embodiments of this application under the control of the chips, processing systems, or functional modules. The AP in the embodiments of this application is a device that provides services to non-AP STAs and can support 802.11 series protocols or subsequent protocols. For example, an access point can be an access point for terminals (such as mobile phones) to enter a wired (or wireless) network, mainly deployed in homes, buildings, and parks, with a typical coverage radius of tens to hundreds of meters; of course, it can also be deployed outdoors. For example, an AP can be a communication server, router, switch, bridge, mobile phone, or computer; APs can include various forms of macro base stations, micro base stations, and repeater stations. Of course, an AP can also be an AP belonging to a multi-link device (MLD), or a co-located AP, etc.

[0648] A non-AP STA is a device with wireless communication capabilities that supports communication or sensing using WLAN protocols and has the ability to communicate or sense with other non-AP STAs or access points in a WLAN network. For example, a non-AP STA is any user communication device that allows a user to communicate or sense with an AP and thus communicate with the WLAN. This device with wireless communication capabilities can be a complete device, or it can be a chip, processing system, or functional module installed in a complete device. Devices with these chips, processing systems, or functional modules can implement the methods and functions of the embodiments of this application under the control of the chips, processing systems, or functional modules. For example, a non-AP STA can be a wireless communication chip, a wireless sensor, or a wireless communication terminal, and can also be referred to as a user. Another example is a non-AP STA that supports Wi-Fi communication, such as a mobile phone, a tablet computer, a set-top box, a smart TV, a smart wearable device, an in-vehicle communication device, or a computer. Of course, a non-AP STA can also be a non-AP STA belonging to an MLD or a co-located STA.

[0649] A multi-link device comprises multiple affiliated sites, which can be physical or logical sites. Each site can operate on a link, a frequency band, or a channel, etc. The affiliated sites shown here can be APs or non-AP STAs.

[0650] Figure 1 is a schematic diagram of an architecture of a communication system provided in an embodiment of this application. The communication system includes at least one AP / AP MLD and at least one non-AP STA / non-AP STA MLD. Figure 1 exemplarily shows one AP and two non-AP STAs, such as non-AP STA1 and non-AP STA2.

[0651] Figure 1 uses a non-AP STA as a mobile phone and an AP as a router as an example, and does not imply any limitation on the AP and non-AP STA types in the embodiments of this application.

[0652] The following describes the terms used in the embodiments of this application.

[0653] 1. PAPR

[0654] In the time domain, the amplitude of a wireless signal is constantly changing, therefore its transmit power is not constant. PAPR (Peak Power Ratio) refers to the ratio of the signal's peak power to its average power over a period of time. Since an Orthogonal Frequency Division Multiplexing (OFDM) symbol is composed of multiple independently modulated subcarrier signals superimposed, when the signals on each subcarrier are in the same or similar phase, the superimposed signal will be modulated by the same initial phase signal, resulting in a large instantaneous power peak, which in turn leads to a high PAPR. Because the dynamic range of a typical power amplifier is limited, OFDM symbols with a high PAPR are prone to entering the nonlinear region of the power amplifier, causing nonlinear distortion, significant spectral spread interference, and in-band signal distortion, resulting in a severe degradation of the overall system performance.

[0655] Since PAPR is the ratio of peak power to average signal power, PAPR can be effectively reduced when subcarriers in a DRU are uniformly distributed within the DRU's discrete bandwidth. In other words, the PAPR of the fields transmitted through the DRU can be effectively reduced.

[0656] 2. Multiple Resource Unit (MRU)

[0657] In terms of bandwidth configuration, the following bandwidth configurations are supported: 20MHz, 40MHz, 80MHz, 160MHz, 80+80MHz, and 320MHz. The difference between 160MHz and 80+80MHz is that the former is a continuous frequency band, while the latter's two 80MHz bands can be separated.

[0658] In terms of bandwidth configuration, it can also support situations where at least one 20MHz band of 80MHz or higher is unavailable. Optionally, a sub-channel has a bandwidth of 20MHz, therefore 20MHz is also referred to as a 20MHz sub-channel.

[0659] Figure 2a is a schematic diagram of the distribution of 484+242-tone MRUs in 80MHz. As shown in Figure 2a, when a 20MHz subchannel in 80MHz is unavailable, the bandwidth can be divided into 484+242-tone MRUs (i.e., continuous resource units containing 484 subcarriers and continuous resource units containing 242 subcarriers). 484+242-tone MRU1 represents the first 20MHz subchannel being unavailable, 484+242-tone MRU2 represents the second 20MHz subchannel being unavailable, 484+242-tone MRU3 represents the third 20MHz subchannel being unavailable, and 484+242-tone MRU4 represents the fourth 20MHz subchannel being unavailable.

[0660] Figure 2b is a schematic diagram of the subcarrier planning and RU distribution for 80MHz. As shown in Figure 2b, a 484-tone RU subcarrier includes two 242-tone RU subcarriers, a 242-tone RU subcarrier includes two 106-tone RU subcarriers and one 26-tone RU subcarrier, a 106-tone RU subcarrier includes two 52-tone RU subcarriers, and a 52-tone RU subcarrier includes two 26-tone RU subcarriers. In other words, a 484-tone RU can be split into two 242-tone RUs, a 242-tone RU can be split into two 106-tone RUs and one 26-tone RU, a 106-tone RU can be split into two 52-tone RUs, and a 52-tone RU can be split into two 26-tone RUs. In Figure 2b, 484L and 484R represent the left and right halves of the 484-tone RU, respectively, each containing 242 subcarriers. This is another way of representing 484+5DC.

[0661] Taking a subcarrier spacing of 78.125 kHz as an example, there are 1024 subcarriers in an 80 MHz frequency band. The indices of these 1024 subcarriers are -512, -511, ..., -1, 0, 1, 2, ..., 510, 511. Alternatively, the index range of these 1024 subcarriers is [-512:511]. Subcarriers with indices greater than 0 are located in the positive half-frequency band, and subcarriers with indices less than 0 are located in the negative half-frequency band.

[0662] In this application, [a:b:c] can refer to all integers from a to c (where a and c are also integers), with a step size of b. That is: a, (a+b), (a+2b), (a+3b), ..., c. Whether the last value c can be obtained depends on whether ca is exactly an integer multiple of b; if not, element c is not included. When b equals 1, [a:c] can usually be used to represent [a:1:c].

[0663] Table 1 provides an example of the RU numbers and subcarrier ranges within an 80MHz band. RU i represents the RU number, and [a:c] indicates that the subcarrier range of the RU is from a to c, including a and c themselves. The RU number can also be referred to as the RU index.

[0664] Table 1

[0665] Table 2 exemplarily illustrates the subcarrier allocation in an 80MHz region where a non-contiguous 20MHz bandwidth is unavailable. The available 60MHz within the 80MHz region comprises a total of 782 subcarriers. In Table 2, 484-tone RU1 is RU1 in the 484-tone RU list of Table 1, and 484-tone RU2 is RU2 in the 484-tone RU list of Table 1. Similarly, 242-tone RU1, 242-tone RU2, 242-tone RU3, and 242-tone RU4 represent RU1, RU2, RU3, and RU4 in the 242-tone RU list of Table 1, respectively.

[0666] Table 2

[0667] The aforementioned RUs are all continuous. For smaller RUs, in scenarios with limited power spectral density, the transmit power is limited by the RU bandwidth, the maximum transmit power is relatively small, and the transmission rate and distance are greatly limited.

[0668] 3. Distributed Resource Unit (DRU)

[0669] To improve the maximum transmit power of each RU during LPI uplink transmission, the concept of DRU was proposed. This concept increases the maximum transmit power allowed in LPI mode by discretely distributing the subcarriers contained in each RU across the entire or larger bandwidth.

[0670] Table 3 illustrates, for example, the relationship between maximum transmit power and bandwidth in an LPI scenario.

[0671] Table 3

[0672] As shown in Table 1, the maximum transmission power of the device increases with the increase in transmission bandwidth. Therefore, DRU can be used to distribute the subcarriers of the original contiguous resource units over a larger bandwidth range, thereby improving the transmission power.

[0673] 4. Maximum power spectral density

[0674] Maximum power spectral density (MPD) refers to the maximum transmit power within 1 MHz. In other words, MPD is limited by a transmit power of no more than x dBm (dBm = 10lg(mW), where lg represents the logarithm to base 10). For example, 1 MHz / 78.125 kHz = 12.8 ≈ 13. That is, there are approximately 13 subcarriers within 1 MHz. According to the MPD constraint, the more discrete the subcarriers in the DRU, the greater the transmit power of each subcarrier. For example, if there is only one subcarrier within 1 MHz, then the power within that 1 MHz equals the power of that single subcarrier, allowing that subcarrier to achieve maximum power gain. Therefore, under MPD constraints, the fewer subcarriers in each 1 MHz of the DRU, the more discrete the subcarriers within the DRU, thus effectively increasing the transmit power of the subcarriers.

[0675] 5. Smoothing

[0676] During channel estimation, the receiver can perform frequency-domain channel smoothing (such as weighted averaging) on ​​the channel estimation results of adjacent subcarriers, thereby improving the accuracy of channel estimation. When any two 52-tone DRUs satisfy a shift relationship, the receiver can still use the same smoothing method for channel estimation, even for different 52-tone DRUs, reducing implementation complexity. Conversely, when any two 52-tone DRUs do not satisfy a shift relationship, the receiver needs to use different smoothing methods for channel estimation for different 52-tone DRUs, resulting in higher complexity.

[0677] The following describes the methods involved in the embodiments of this application.

[0678] This application provides a communication method and apparatus that can effectively improve the transmission power of subcarriers. The designed 52-tone DRU ensures that there is only one subcarrier within each 1MHz band, achieving maximum power gain. Furthermore, any two 52-tone DRUs satisfy a shift relationship, reducing the complexity of smoothing processing and overall implementation.

[0679] Figure 3 is a flowchart illustrating the communication method provided in an embodiment of this application. The descriptions of the first and second devices involved in this method are as above and will not be detailed here. As shown in Figure 3, the method includes:

[0680] In one possible implementation, the method shown in Figure 3 includes step 301.

[0681] 301. The first device generates some or all of the fields of the PPDU.

[0682] In one possible implementation, the first device is a non-AP STA, and the second device is an AP. Before the first device generates the PPDU, the method shown in Figure 3 further includes: the AP sending a trigger frame, which is received by the non-AP STA. The trigger frame includes an RU allocation subfield and a user information subfield. The RU allocation subfield is used to indicate the location and size of the RU, and the user information subfield is used to indicate the first device. The RU allocation subfield and the user information subfield jointly indicate the RU allocated to the first device. The RU shown here includes a DRU. This DRU is the DRU involved in step 302 below.

[0683] In one possible implementation, the first device is an AP, and the second device is a non-AP STA. The DRU allocation information can be included in the signaling (SIG) field of the PPDU. This is exemplified by the DRU discussed in step 302 below. If the PPDU is a UHR PPDU, the SIG field is UHR-SIG. Similarly, if the PPDU is an EHT PPDU, the SIG field is EHT-SIG. And if the PPDU is an IMMW PPDU, the SIG field is IMMW-SIG. The types of PPDUs listed here are merely examples; as standards evolve, other types of PPDUs may emerge, which will not be listed here. Transmitting some or all fields of the PPDU on the DRU can increase the frequency domain diversity gain of downlink transmission and improve transmission performance.

[0684] 302. The first device transmits some or all fields of the PPDU on the DRU. Correspondingly, the second device receives some or all fields of the PPDU on the DRU.

[0685] A DRU is one of the subcarrier plans corresponding to a discrete bandwidth of 60MHz. For example, this DRU is a 52-tone DRU in the 60MHz subcarrier plan. Another example is a 106-tone DRU in the 60MHz subcarrier plan. Yet another example is a 242-tone DRU in the 60MHz subcarrier plan. And yet another example is a 26-tone DRU in the 60MHz subcarrier plan.

[0686] The discrete bandwidth of 60MHz is the 60MHz of 80MHz that is not punched.

[0687] As an example, the highest frequency 20MHz in the 80MHz band is punctured. That is, the fourth 20MHz band in the 80MHz band is punctured in ascending order of frequency. For example, with a subcarrier spacing of 78.125kHz, there are a total of 1024 subcarriers in the 80MHz bandwidth, with subcarrier indices of -512, ..., 0, ..., 511. These 1024 subcarriers include 23 guard subcarriers. The 12 subcarriers with indices [-512:-501] and the 11 subcarriers with indices [501:511] are within the guard interval and cannot be used. The 5 subcarriers with indices [-2:2] are near the DC subcarriers and also cannot be used. In the case of a 20MHz preamble puncture, 242 of the 1024 subcarriers are unusable. Therefore, the number of usable subcarriers out of the 1024 subcarriers is 782. With the last 20MHz in the 80MHz range being punctured, the index of the 60MHz subcarrier is [-500:-3,3:253].

[0688] As another example, the lowest 20MHz frequency in the 80MHz range is punched. That is, the first 20MHz in the 80MHz range is punched in ascending order of frequency. For example, the index of the 60MHz subcarrier is [-253:-3,3:500].

[0689] The characteristics required for subcarrier planning corresponding to 60MHz are described below, but will not be detailed here.

[0690] Transmitting part or all of the fields of the PPDU on the DRU indicates that these fields are formed by performing an inverse fourier transform on the values ​​carried on the subcarriers of the DRU. The values ​​carried on the subcarriers of the DRU are processed through an inverse fourier transform and other processing operations to form the fields. It should be understood that the inverse fourier transform and other processing operations here refer to the general processing of converting frequency domain signals to time domain signals, and this application embodiment does not limit this. The inverse fourier transform includes the inverse fast fourier transform (IFFT).

[0691] As one possible implementation, some or all of the fields in a PPDU may include data fields.

[0692] Figures 4a and 4b are schematic diagrams illustrating the data field transmission process provided in the embodiments of this application. Figure 4a illustrates low-density parity check (LDPC) encoding as an example, and Figure 4b illustrates binary convolutional code (BCC) encoding as an example.

[0693] As shown in Figure 4a, the data to be transmitted can pass through the following modules: forward error correction (FEC) pre-FEC padding, scrambler, LDPC encoder, FEC post-FEC padding, stream parser, constellation mapper, LDPC tone mapper, cyclic shift diversity per spatial stream (CSD per SS), spatial and frequency mapping, IDFT, guard interval (GI) insertion and windowing, and analog and radio frequency (RF).

[0694] As shown in Figure 4b, the data to be transmitted can pass through the following modules: forward error correction (FEC) pre-FEC padding, scrambler, BCC encoder, FEC post-FEC padding, BCC interleaver, constellation mapper, stream parser, CSD per SS, spatial and frequency mapping, IDFT, insert guard interval and window, and analog and RF.

[0695] The stream parser can be used to allocate bitstreams to different spatial streams, and further process each stream accordingly. The constellation mapper can be used to map to BPSK, BPSK-dual carrier modulation (DCM), QPSK, 16-quadrature amplitude modulation (QAM), 64-QAM, 256-QAM, 1024-QAM, or 4096-QAM constellation points. Spatial and frequency mapping can be used to map data from different users to different spatial streams and different subcarriers. That is, spatial and frequency mapping can be used to map data from different users to data subcarriers in the DRU, and to map pilot values ​​to pilot subcarriers. The mapping process for pilot subcarriers is not shown in Figures 4a and 4b. For descriptions of the other modules shown in Figures 4a and 4b, please refer to relevant standards; they will not be detailed here.

[0696] The description of the second device receiving data fields on the DRU can be found in Figure 4a or Figure 4b. The process of receiving data fields is the reverse process of sending data fields.

[0697] As another possible implementation, some or all fields of the PPDU include a long training field (LTF). The LTF transmission process may include at least one of the following:

[0698] (a) Sequence generation: Generate LTF sequences in the frequency domain over the bandwidth.

[0699] (b) Matrix mapping: Apply the P matrix to the data subcarriers of the LTF sequence and the R matrix to the pilot subcarriers of the EHT-LTF sequence.

[0700] (c) Cyclic shift diversity (CSD): Apply CSD to each spatial stream.

[0701] (d) Spatial mapping: applying the Q matrix.

[0702] (e) Inverse Discrete Fourier Transform (IDFT): Calculate the inverse discrete Fourier transform.

[0703] (f) Insert GI and apply windowing: Preset GI and apply windowing.

[0704] (g) Analog and Radio Frequency (RF): Based on the center frequency of the desired channel, the complex baseband waveforms associated with each transmit chain are converted into RF signals and transmitted.

[0705] For specific explanations of (a) to (g), please refer to the relevant standards, which will not be elaborated here.

[0706] The second device receives the LTF on the DRU. Refer to (a) to (g) above for an explanation. The process of receiving the LTF is the reverse process of sending the LTF.

[0707] The fields sent on the DRU may also include other fields, which will not be listed here.

[0708] 303. The second device parses some or all of the fields of the PPDU.

[0709] Since the parsing process can be considered the reverse of the generation process, the explanation of the second device parsing some or all fields of the PPDU can be found in the description in step 302, and will not be elaborated here.

[0710] The following describes the features satisfied by the subcarrier planning corresponding to 60MHz involved in the embodiments of this application.

[0711] (1) 52-tone DRU

[0712] The subcarrier planning corresponding to 60MHz includes 12 52-tone DRUs. The index difference between any two adjacent subcarriers in these 52-tone DRUs is an integer multiple of 13. The subcarrier indices of any two 52-tone DRUs in these 12 52-tone DRUs satisfy a translation relationship. The integer multiple of 13 can include, but is not limited to, 13, 26, or 39.

[0713] As an example, in a 52-tone DRU, the index difference between any two adjacent subcarriers is 13. For instance, the index difference between the nth subcarrier and the (n+1)th subcarrier in a 52-tone DRU is 13. n = 1, 2, 3, ..., 51. This example uses the lowest frequency subcarrier in the 52-tone DRU as the first subcarrier. When the lowest frequency subcarrier in the 52-tone DRU is the 0th subcarrier, n = 0, 1, 2, ..., 50. For ease of description, the following examples will use the lowest frequency subcarrier as the first subcarrier.

[0714] As another example, the index difference between two adjacent subcarriers in the first part of a 52-tone DRU is 13, and the index difference between two adjacent subcarriers in the second part of the 52-tone DRU is 26 or 39.

[0715] For example, in a 52-tone DRU, the index difference between two adjacent subcarriers with an index less than 0 is 13, and the index difference between two adjacent subcarriers with an index greater than 0 is also 13. As another example, in a 52-tone DRU, the index difference between two adjacent subcarriers located on opposite sides of a DC subcarrier is 26 or 39; or, in other words, the index difference between the subcarrier with the smallest index in the positive half-frequency and the subcarrier with the largest index in the negative half-frequency is 26 or 39.

[0716] Figure 5a is a schematic diagram of the distribution of a 52-tone DRU provided in an embodiment of this application. As shown in Figure 5a, the index difference between some adjacent subcarriers in the 52-tone DRU is 13, and the index difference between some adjacent subcarriers is 26 or 39. The longer lines in Figure 5a represent the subcarriers included in the 52-tone DRU, and the ellipsis indicates the subcarriers omitted.

[0717] For example, in a 52-tone DRU, the index difference between two subcarriers with larger indices in the negative half-frequency is 26 or 39, and the index difference between two subcarriers with smaller indices in the positive half-frequency is also 26 or 39. For example, in a 52-tone DRU, the index difference between two adjacent subcarriers among multiple subcarriers with smaller indices in the negative half-frequency is 26 or 39. For example, in a 52-tone DRU, the index difference between two adjacent subcarriers among multiple subcarriers with larger indices in the positive half-frequency is 26 or 39. The terms "larger" or "smaller" here are relative to the positive or negative half-frequency.

[0718] As another example, the index difference between two adjacent subcarriers in the first part of the 52-tone DRU is 13, the index difference between two adjacent subcarriers in the second part of the 52-tone DRU is 26, and the index difference between two adjacent subcarriers in the third part of the 52-tone DRU is 39.

[0719] Figure 5b is a schematic diagram of the distribution of a 52-tone DRU provided in an embodiment of this application. As shown in Figure 5b, the index difference between two adjacent subcarriers located on either side of the DC subcarrier in the 52-tone DRU is 39; the index difference between two subcarriers with smaller indices located in the negative half-frequency is 26; the index difference between two subcarriers with larger indices located in the positive half-frequency is 26; and the index difference between two adjacent subcarriers in the remaining portion is 13. Examples of index differences are not listed here.

[0720] For two 52-tone DRUs that satisfy a translation relationship, the subcarrier indices of one 52-tone DRU after all subcarriers are translated by the same translation value are the same as the subcarrier indices of the other 52-tone DRU. Translation includes rightward or leftward translation.

[0721] In other words, the index obtained by shifting the nth subcarrier in one 52-tone DRU by m indices is the same as the index of the nth subcarrier in another 52-tone DRU.

[0722] Alternatively, the index of the nth subcarrier in one 52-tone DRU + m = the index of the nth subcarrier in another 52-tone DRU. m is an integer.

[0723] Figure 6 is a translation diagram provided in an embodiment of this application. As shown in Figure 6, any two of the twelve 52-tone DRUs are the first DRU and the second DRU. The second DRU can be obtained by shifting each subcarrier in the first DRU to the right by m indices. Or, in other words, the index of the nth subcarrier in the first DRU + m = the index of the nth subcarrier in the second DRU.

[0724] For example, if the subcarrier index of the first DRU is [-494:13:-26,13:13:195] and m=7, then the subcarrier index of the second DRU can be [-487:13:-19,20:13:202].

[0725] For example, if the subcarrier index of the first DRU is [-494:13:-26,13:13:195] and m=6, then the subcarrier index of the second DRU can be [-488:13:-20,19:13:201].

[0726] For example, if the subcarrier index of the first DRU is [-491:13:-23,16:13:198] and m=7, then the subcarrier index of the second DRU is [-484:13:-16,23:13:205]. If m=-9, then the subcarrier index of the second DRU is [-493:13:-25,14:13:196].

[0727] In one possible implementation, the index difference between the two 52-tone DRUs that constitute each 106-tone DRU is the same. Alternatively, the translation values ​​corresponding to the two 52-tone DRUs that constitute each 106-tone DRU are the same. This ensures that any two 106-tone DRUs also satisfy the translation relationship.

[0728] In other words, the following translation values ​​are all the same: the translation values ​​of the two 52-tone DRUs corresponding to 106-tone DRU 1, the translation values ​​of the two 52-tone DRUs corresponding to 106-tone DRU 2, the translation values ​​of the two 52-tone DRUs corresponding to 106-tone DRU 3, the translation values ​​of the two 52-tone DRUs corresponding to 106-tone DRU 4, the translation values ​​of the two 52-tone DRUs corresponding to 106-tone DRU 5, and the translation values ​​of the two 52-tone DRUs corresponding to 106-tone DRU 6.

[0729] For example, the index difference between the nth subcarrier in 52-tone DRU i and the nth subcarrier in 52-tone DRU i+1 is 7 or 6. i = 1, 3, 5, 7, 9, 11. n = 1, 2, 3, ..., 52. Alternatively, the index obtained by shifting all subcarriers in 52-tone DRU i to the right by 7 (or 6) indices is the same as the index of the subcarriers in 52-tone DRU i+1.

[0730] In other words, the translation value between 52-tone DRU 1 and 52-tone DRU 2 is 7, the translation value between 52-tone DRU 3 and 52-tone DRU 4 is 7, the translation value between 52-tone DRU 5 and 52-tone DRU 6 is 7, the translation value between 52-tone DRU 7 and 52-tone DRU 8 is 7, the translation value between 52-tone DRU 9 and 52-tone DRU 10 is 7, and the translation value between 52-tone DRU 11 and 52-tone DRU 12 is 7. Alternatively, the translation value between 52-tone DRU 1 and 52-tone DRU 2 is 6, the translation value between 52-tone DRU 3 and 52-tone DRU 4 is 6, the translation value between 52-tone DRU 5 and 52-tone DRU 6 is 6, the translation value between 52-tone DRU 7 and 52-tone DRU 8 is 6, the translation value between 52-tone DRU 9 and 52-tone DRU 10 is 6, and the translation value between 52-tone DRU 11 and 52-tone DRU 12 is 6.

[0731] In one possible implementation, one 52-tone DRU corresponds to one subcarrier group, and different 52-tone DRUs correspond to different subcarrier groups. The number of subcarriers in this subcarrier group is greater than 52. One 52-tone DRU corresponding to one subcarrier means that the subcarriers of this 52-tone DRU are contained within this subcarrier group. Each of the 12 52-tone DRUs corresponds to one subcarrier group, and the 12 52-tone DRUs correspond to a total of 12 subcarrier groups. These 12 subcarrier groups are 12 of the following 13 subcarrier groups:

[0732] The index of the subcarriers in the first subcarrier group is [-494:13:-13,13:13:247];

[0733] The index of the subcarriers in the second subcarrier group is [-493:13:-12,14:13:248];

[0734] The index of the subcarriers in the third subcarrier group is [-492:13:-11,15:13:249];

[0735] The index of the subcarriers in the 4th subcarrier group is [-491:13:-10,3:13:250];

[0736] The index of the subcarrier in the 5th subcarrier group is [-490:13:-9,4:13:251];

[0737] The index of the subcarrier in the 6th subcarrier group is [-489:13:-8,5:13:252];

[0738] The index of the subcarrier in the 7th subcarrier group is [-488:13:-7,6:13:253];

[0739] The index of the subcarrier in the 8th subcarrier group is [-500:13:-6,7:13:241];

[0740] The index of the subcarrier in the 9th subcarrier group is [-499:13:-5,8:13:242];

[0741] The index of the subcarrier in the 10th subcarrier group is [-498:13:-4,9:13:243];

[0742] The index of the subcarriers in the 11th subcarrier group is [-497:13:-3,10:13:244];

[0743] The index of the subcarriers in the 12th subcarrier group is [-496:13:-15,11:13:245];

[0744] The index of the subcarriers in the 13th subcarrier group is [-495:13:-14,12:13:246].

[0745] Any one of the 13 subcarrier groups mentioned above can guarantee that there is only one subcarrier within each 1MHz bandwidth, and all subcarriers are approximately uniformly distributed. Therefore, 52 subcarriers can be selected from any of the above subcarrier groups to form a 52-tone DRU.

[0746] As one possible implementation, combining the features satisfied by the 52-tone DRU described above, it is possible to construct 12 subcarriers of the 52-tone DRU in the subcarrier index corresponding to 60MHz. The subcarriers of the 52-tone DRU constructed in this way fall within the protection scope of the embodiments of this application.

[0747] As another possible implementation, by combining the features of the 52-tone DRU described above, and any 12 subcarrier groups from the 13 subcarrier groups described above, the subcarriers of the 52-tone DRU can be constructed. The subcarriers of the 52-tone DRU constructed in this way fall within the protection scope of the embodiments of this application. For example, by combining the features of the 52-tone DRU described above, and the 1st to 6th subcarrier groups, and the 8th to 13th subcarrier groups from the 13 subcarrier groups described above, as a possible implementation, the subcarriers of the 52-tone DRU are shown in Tables 4 and 5. Furthermore, by combining the features of the 52-tone DRU described above, and the 2nd to 13th subcarrier groups from the 13 subcarrier groups described above, as a possible implementation, the subcarriers of the 52-tone DRU are shown in Tables 6 and 7. As another possible implementation, the subcarriers of the 52-tone DRU are shown in Table 8. It should be understood that the subcarriers of the 52-tone DRU shown in Tables 4 to 8 are only examples. In combination with the features of the 52-tone DRU introduced above, and the 13 subcarrier groups, different subcarriers can be designed, which will not be listed here.

[0748] As another possible implementation, combining any 12 subcarrier groups from the 13 subcarrier groups described above, 52 subcarriers can be randomly selected from each subcarrier group to construct a 52-tone DRU. Different selection methods will result in different subcarriers for the final 52-tone DRU. The subcarriers of the 52-tone DRU constructed in this way fall within the protection scope of the embodiments of this application.

[0749] Optionally, the subcarrier planning corresponding to 60MHz does not include 26-tone DRUs.

[0750] Optionally, the subcarrier planning corresponding to 60MHz includes 26-tone DRUs. The subcarriers of the 26-tone DRUs are described in reference to Table 4, and will not be detailed here.

[0751] In this embodiment, the index difference between two adjacent subcarriers in the 52-tone DRU is an integer multiple of 13. This not only ensures that there is only one subcarrier within each 1MHz, increasing the transmit power of each subcarrier and achieving maximum power gain, but also effectively reduces PAPR. Furthermore, the subcarrier indices of any two 52-tone DRUs satisfy a shift relationship. For different 52-tone DRUs, the second device can employ the same smoothing method, effectively reducing the complexity of the smoothing process and thus the overall implementation complexity.

[0752] (2) 106-tone DRU

[0753] The subcarrier plan corresponding to 60MHz includes six 106-tone DRUs, and each 106-tone DRU subcarrier includes two 52-tone DRU subcarriers. The six 106-tone DRU subcarriers include twelve 52-tone DRU subcarriers.

[0754] Optionally, a subcarrier of a 106-tone DRU may also include two subcarriers from the two subcarrier groups corresponding to the two 52-tone DRUs. Optionally, a subcarrier of a 106-tone DRU may also include two subcarriers from one of the 13 subcarrier groups, excluding the 12 subcarrier groups corresponding to the 52-tone DRU. Optionally, a subcarrier of a 106-tone DRU may also include two subcarriers; the specific details of these two subcarriers are not limited in this embodiment. The subcarriers of the 52-tone DRU are described above and will not be repeated here. The description of subcarrier groups is also described above and will not be repeated here.

[0755] In one possible implementation, the subcarriers of 106-tone DRU 1 include the subcarriers of 52-tone DRU 1 and 52-tone DRU 2.

[0756] Optionally, the subcarriers of the 106-tone DRU 1 also include two subcarriers from the subcarrier group corresponding to the 52-tone DRU 1, excluding the 52 subcarriers in the 52-tone DRU 1. For example, the subcarrier group corresponding to the 52-tone DRU 1 is the first subcarrier group, and the subcarriers of this first subcarrier group are [-494:13:-13,13:13:247]. This first subcarrier group contains 5 subcarriers in addition to the 52 subcarriers in the 52-tone DRU 1. Therefore, the subcarriers of the 106-tone DRU 1 include the subcarriers of the 52-tone DRU 1, the subcarriers of the 52-tone DRU 2, and 2 of the aforementioned 5 subcarriers.

[0757] Optionally, the subcarriers of 106-tone DRU 1 also include two subcarriers from the subcarrier group corresponding to 52-tone DRU 2, excluding the 52 subcarriers in 52-tone DRU 2. For example, the subcarrier group corresponding to 52-tone DRU 2 is the 8th subcarrier group, and the subcarriers of this 8th subcarrier group are [-500:13:-6,7:13:241]. This 8th subcarrier group contains 6 subcarriers in addition to the 52 subcarriers in 52-tone DRU 2. Therefore, the subcarriers of 106-tone DRU 1 include the subcarriers of 52-tone DRU 1, the subcarriers of 52-tone DRU 2, and 2 of the aforementioned 6 subcarriers.

[0758] Optionally, the subcarrier of the 106-tone DRU 1 may also include one subcarrier from the subcarrier group corresponding to the 52-tone DRU 1, excluding the 52 subcarriers in the 52-tone DRU 1, and the subcarrier of the 106-tone DRU 1 may also include one subcarrier from the subcarrier group corresponding to the 52-tone DRU 2, excluding the 52 subcarriers in the 52-tone DRU 2. For example, the subcarrier of the 106-tone DRU 1 may include the subcarriers of the 52-tone DRU 1, the subcarriers of the 52-tone DRU 2, one of the aforementioned five subcarriers (e.g., index 208), and one of the aforementioned six subcarriers (e.g., index 215).

[0759] In one possible implementation, the subcarriers of 106-tone DRU 2 include the subcarriers of 52-tone DRU 3 and 52-tone DRU 4.

[0760] Optionally, the subcarriers of the 106-tone DRU 2 also include two subcarriers in the subcarrier group corresponding to the 52-tone DRU 3, excluding the 52 subcarriers in the 52-tone DRU 3. Optionally, the subcarriers of the 106-tone DRU 2 also include two subcarriers in the subcarrier group corresponding to the 52-tone DRU 4, excluding the 52 subcarriers in the 52-tone DRU 4. Optionally, the subcarriers of the 106-tone DRU 2 also include one subcarrier (e.g., index 211) in the subcarrier group corresponding to the 52-tone DRU 3, excluding the 52 subcarriers in the 52-tone DRU 3, and one subcarrier (e.g., index 218) in the subcarrier group corresponding to the 52-tone DRU 4, excluding the 52 subcarriers in the 52-tone DRU 4. The descriptions of the two subcarriers in the 106-tone DRU, excluding the two 52-tone DRUs, will not be listed here.

[0761] In one possible implementation, the subcarriers of 106-tone DRU 3 include the subcarriers of 52-tone DRU 5 and 52-tone DRU 6.

[0762] Optionally, the subcarriers of the 106-tone DRU 3 also include two subcarriers in the subcarrier group corresponding to the 52-tone DRU 5, excluding the 52 subcarriers in the 52-tone DRU 5. Optionally, the subcarriers of the 106-tone DRU 3 also include two subcarriers in the subcarrier group corresponding to the 52-tone DRU 6, excluding the 52 subcarriers in the 52-tone DRU 6. Optionally, the subcarriers of the 106-tone DRU 3 also include one subcarrier (e.g., index 209) in the subcarrier group corresponding to the 52-tone DRU 5, excluding the 52 subcarriers in the 52-tone DRU 5, and the subcarriers of the 106-tone DRU 3 also include one subcarrier (e.g., index 216) in the subcarrier group corresponding to the 52-tone DRU 6, excluding the 52 subcarriers in the 52-tone DRU 6. The descriptions of the two subcarriers in the 106-tone DRU, excluding the two 52-tone DRUs, will not be listed here.

[0763] In one possible implementation, the subcarriers of 106-tone DRU 4 include the subcarriers of 52-tone DRU 7 and 52-tone DRU 8.

[0764] Optionally, the subcarriers of the 106-tone DRU 4 also include two subcarriers in the subcarrier group corresponding to the 52-tone DRU 7, excluding the 52 subcarriers in the 52-tone DRU 7. Optionally, the subcarriers of the 106-tone DRU 4 also include two subcarriers in the subcarrier group corresponding to the 52-tone DRU 8, excluding the 52 subcarriers in the 52-tone DRU 8. Optionally, the subcarriers of the 106-tone DRU 4 also include one subcarrier (e.g., index 212) in the subcarrier group corresponding to the 52-tone DRU 7, excluding the 52 subcarriers in the 52-tone DRU 7, and the subcarriers of the 106-tone DRU 4 also include one subcarrier (e.g., index 219) in the subcarrier group corresponding to the 52-tone DRU 8, excluding the 52 subcarriers in the 52-tone DRU 8. The descriptions of the two subcarriers in the 106-tone DRU, excluding the two 52-tone DRUs, will not be listed here.

[0765] In one possible implementation, the subcarriers of 106-tone DRU 5 include the subcarriers of 52-tone DRU 9 and 52-tone DRU 10.

[0766] Optionally, the subcarriers of the 106-tone DRU 5 also include two subcarriers in the subcarrier group corresponding to the 52-tone DRU 9, excluding the 52 subcarriers in the 52-tone DRU 9. Optionally, the subcarriers of the 106-tone DRU 5 also include two subcarriers in the subcarrier group corresponding to the 52-tone DRU 10, excluding the 52 subcarriers in the 52-tone DRU 10. Optionally, the subcarriers of the 106-tone DRU 5 also include one subcarrier (e.g., index 210) in the subcarrier group corresponding to the 52-tone DRU 9, excluding the 52 subcarriers in the 52-tone DRU 9, and the subcarriers of the 106-tone DRU 5 also include one subcarrier (e.g., index 217) in the subcarrier group corresponding to the 52-tone DRU 10, excluding the 52 subcarriers in the 52-tone DRU 10. The descriptions of the two subcarriers in the 106-tone DRU, excluding the two 52-tone DRUs, will not be listed here.

[0767] In one possible implementation, the subcarriers of 106-tone DRU 6 include the subcarriers of 52-tone DRU 11 and 52-tone DRU 12.

[0768] Optionally, the subcarriers of the 106-tone DRU 6 also include two subcarriers in the subcarrier group corresponding to the 52-tone DRU 11, excluding the 52 subcarriers in the 52-tone DRU 11. Optionally, the subcarriers of the 106-tone DRU 6 also include two subcarriers in the subcarrier group corresponding to the 52-tone DRU 12, excluding the 52 subcarriers in the 52-tone DRU 12. Optionally, the subcarriers of the 106-tone DRU 6 also include one subcarrier in the subcarrier group corresponding to the 52-tone DRU 11 (e.g., index 213), excluding the 52 subcarriers in the 52-tone DRU 11, and one subcarrier in the subcarrier group corresponding to the 52-tone DRU 12 (e.g., index 220). The descriptions of the two subcarriers in the 106-tone DRU, excluding the two 52-tone DRUs, will not be listed here.

[0769] In one possible implementation, any two of the six 106-tone DRUs satisfy a translation relationship. For example, the index of the nth subcarrier in one 106-tone DRU after shifting it by x indices is the same as the index of the nth subcarrier in another 106-tone DRU. Alternatively, the index of the nth subcarrier in one 106-tone DRU + x equals the index of the nth subcarrier in another 106-tone DRU. n = 1, 2, 3, ..., 106. x is an integer. Translation includes rightward or leftward translation.

[0770] As an example, the following translation values ​​are all the same: the translation values ​​of the two 52-tone DRUs corresponding to 106-tone DRU 1, the translation values ​​of the two 52-tone DRUs corresponding to 106-tone DRU 2, the translation values ​​of the two 52-tone DRUs corresponding to 106-tone DRU 3, the translation values ​​of the two 52-tone DRUs corresponding to 106-tone DRU 4, the translation values ​​of the two 52-tone DRUs corresponding to 106-tone DRU 5, and the translation values ​​of the two 52-tone DRUs corresponding to 106-tone DRU 6.

[0771] For example, the translation value between 52-tone DRU 1 and 52-tone DRU 2 is 7, the translation value between 52-tone DRU 3 and 52-tone DRU 4 is 7, the translation value between 52-tone DRU 5 and 52-tone DRU 6 is 7, the translation value between 52-tone DRU 7 and 52-tone DRU 8 is 7, the translation value between 52-tone DRU 9 and 52-tone DRU 10 is 7, and the translation value between 52-tone DRU 11 and 52-tone DRU 12 is 7. Alternatively, the translation value between 52-tone DRU 1 and 52-tone DRU 2 is 6, the translation value between 52-tone DRU 3 and 52-tone DRU 4 is 6, the translation value between 52-tone DRU 5 and 52-tone DRU 6 is 6, the translation value between 52-tone DRU 7 and 52-tone DRU 8 is 6, the translation value between 52-tone DRU 9 and 52-tone DRU 10 is 6, and the translation value between 52-tone DRU 11 and 52-tone DRU 12 is 6.

[0772] For further explanation regarding the shift values ​​of the two 52-tone DRUs, please refer to the above text; they will not be elaborated upon here.

[0773] As one possible implementation, combining the characteristics satisfied by the 106-tone DRU described above, six subcarriers of the 106-tone DRU in the subcarrier planning corresponding to 60MHz can be constructed. The subcarriers of the 106-tone DRU constructed in this way fall within the protection scope of the embodiments of this application.

[0774] As another possible implementation, by combining the features satisfied by the 12 52-tone DRUs described above, and the features satisfied by the 6 106-tone DRUs described above, subcarriers for the 60MHz subcarrier planning can be constructed. The subcarriers for the 106-tone DRUs constructed in this way fall within the protection scope of the embodiments of this application.

[0775] As another possible implementation, by combining the 12 features satisfied by the 52-tone DRU, the 13 subcarrier groups, and the 6 features satisfied by the 106-tone DRU described above, the subcarrier range of the 106-tone DRU can be constructed. For example, the subcarriers of the 106-tone DRU are shown in Tables 4 to 8. It should be understood that the subcarriers of the 106-tone DRU shown in Tables 4 to 8 are only examples. Different subcarriers can be designed by combining the features of the 52-tone DRU, the 13 subcarrier groups, and the features satisfied by the 106-tone DRU described above, which will not be listed here.

[0776] In this embodiment, a subcarrier of a 106-tone DRU includes two subcarriers of 52-tone DRUs, effectively simplifying resource allocation instructions. Simultaneously, the indices of any two 106-tone DRU subcarriers satisfy a shift relationship; for different 106-tone DRUs, the second device can reuse the same module for frequency domain smoothing, reducing implementation complexity.

[0777] (3)242-tone DRU

[0778] The subcarrier plan corresponding to 60MHz also includes three 242-tone DRUs. One 242-tone DRU includes two 106-tone DRUs. The subcarriers of the three 242-tone DRUs include six 106-tone DRU subcarriers.

[0779] Optionally, a 242-tone DRU may also include some subcarriers from the four subcarrier groups corresponding to the two 106-tone DRUs mentioned above. As shown above, a 52-tone DRU corresponds to one subcarrier group, and the subcarriers of a 106-tone DRU include the subcarriers of two 52-tone DRUs; therefore, two 106-tone DRUs correspond to four subcarrier groups. Optionally, a 242-tone DRU may also include some subcarriers from one of the 13 subcarrier groups, excluding the 12 subcarrier groups. The aforementioned 12 subcarrier groups refer to the 12 subcarrier groups corresponding to the 12 52-tone DRUs. Optionally, a 242-tone DRU may also include 30 subcarriers; the embodiments of this application do not limit the number of these 30 subcarriers.

[0780] In one possible implementation, the subcarriers of 242-tone DRU 1 include the subcarriers of 106-tone DRU 1 and 106-tone DRU 2.

[0781] Optionally, the subcarriers of the 242-tone DRU 1 also include some subcarriers from the four subcarrier groups corresponding to the 106-tone DRU 1 and 106-tone DRU 2. That is, in addition to the 212 subcarriers of the 106-tone DRU 1 and 106-tone DRU 2, the remaining 30 subcarriers of the 242-tone DRU 1 are contained in the four subcarrier groups corresponding to the two 106-tone DRUs.

[0782] Optionally, the subcarriers of the 242-tone DRU 1 also include some subcarriers from one of the 13 subcarrier groups, excluding the 12 subcarrier groups. That is, besides the 212 subcarriers of the 106-tone DRU 1 and 106-tone DRU 2, the remaining 30 subcarriers of the 242-tone DRU 1 are contained in one of the 13 subcarrier groups, excluding the 12 subcarrier groups. The aforementioned 12 subcarrier groups refer to the 12 subcarrier groups corresponding to the 12 52-tone DRUs.

[0783] Optionally, in addition to the 212 subcarriers of 106-tone DRU 1 and 106-tone DRU 2, the remaining 30 subcarriers of the 242-tone DRU 1 are partially contained in the four subcarrier groups corresponding to the two 106-tone DRUs, and the remaining 30 subcarriers are contained in one of the 13 subcarrier groups excluding the 12 subcarrier groups. The aforementioned 12 subcarrier groups refer to the 12 subcarrier groups corresponding to the 12 52-tone DRUs. For example, the subcarrier indices of 106-tone DRU 1 are [-494:13:-26,13:13:208,-487:13:-19,20:13:215], and the subcarrier indices of 106-tone DRU 2 are [-491:13:-23,16:13:211,-484:13:-16,23:13:218]. The two subcarrier groups corresponding to 106-tone DRU 1 are the first subcarrier group (e.g., [-494:13:-13,13:13:247]) and the eighth subcarrier group (e.g., [-500:13:-6,7:13:241]). The two subcarrier groups corresponding to 106-tone DRU 2 are the 4th subcarrier group (e.g., [-491:13:-10, 3:13:250]) and the 11th subcarrier group ([-497:13:-3, 10:13:244]). Of the 13 subcarrier groups, the one excluding the 12 subcarrier groups corresponding to the 12 52-tone DRUs is the 7th subcarrier group (e.g., [-488:13:-7, 6:13:253]). Therefore, the subcarriers of 242-tone DRU 1 include subcarriers with the following indices: [-494:13:-26,13:13:208,-487:13:-19,20:13:215], [-491:13:-23,16:13:211,-484:13:-16,23:13:218]. The remaining 30 subcarriers of 242-tone DRU 1 can be 30 subcarriers with the following indices: [-13,221,234,247,-500,-6,7,228,241], [-10,3,224,237,250,-497,-3,10,231,244], [-488:13:-7,6:13:253].

[0784] In one possible implementation, the subcarriers of 242-tone DRU 2 include the subcarriers of 106-tone DRU 3 and 106-tone DRU 4.

[0785] Optionally, the subcarriers of the 242-tone DRU 2 may also include some subcarriers from the four subcarrier groups corresponding to the 106-tone DRU 3 and 106-tone DRU 4. Optionally, the subcarriers of the 242-tone DRU 2 may also include some subcarriers from one of the 13 subcarrier groups, excluding the 12 subcarrier groups. Optionally, besides the 212 subcarriers of the 106-tone DRU 3 and 106-tone DRU 4, a portion of the remaining 30 subcarriers of the 242-tone DRU 2 are contained in the four subcarrier groups corresponding to these two 106-tone DRUs, and the remaining portion of the remaining 30 subcarriers is contained in one of the 13 subcarrier groups, excluding the 12 subcarrier groups. The aforementioned 12 subcarrier groups refer to the 12 subcarrier groups corresponding to the 12 52-tone DRUs.

[0786] In one possible implementation, the subcarriers of 242-tone DRU 3 include the subcarriers of 106-tone DRU 5 and 106-tone DRU 6.

[0787] Optionally, the subcarriers of 242-tone DRU 3 also include some subcarriers from the four subcarrier groups corresponding to 106-tone DRU 5 and 106-tone DRU 6. Optionally, the subcarriers of 242-tone DRU 3 also include some subcarriers from one of the 13 subcarrier groups, excluding the 12 subcarrier groups. Optionally, besides the 212 subcarriers of 106-tone DRU 5 and 106-tone DRU 6, a portion of the remaining 30 subcarriers of 242-tone DRU 3 are contained in the four subcarrier groups corresponding to these two 106-tone DRUs, and the remaining portion of the remaining 30 subcarriers is contained in one of the 13 subcarrier groups, excluding the 12 subcarrier groups. The aforementioned 12 subcarrier groups refer to the 12 subcarrier groups corresponding to the 12 52-tone DRUs.

[0788] As one possible implementation, by combining the features satisfied by the 106-tone DRU and the features satisfied by the 242-tone DRU described above, three subcarriers of the 242-tone DRU in the subcarrier planning corresponding to 60MHz can be constructed. The subcarriers of the 242-tone DRU constructed in this way fall within the protection scope of the embodiments of this application.

[0789] As another possible implementation, combining the features satisfied by the 106-tone DRU, the 13 subcarrier groups, and the features satisfied by the 242-tone DRU described above, three subcarriers of the 242-tone DRU in the 60MHz subcarrier planning can be constructed. The subcarriers of the 242-tone DRU constructed in this way fall within the protection scope of the embodiments of this application.

[0790] As another possible implementation, combining the features satisfied by the 12 52-tone DRUs, the 13 subcarrier groups, the features satisfied by the 106-tone DRUs, and the features satisfied by the 242-tone DRUs described above, we can construct the three subcarriers of the 242-tone DRUs in the subcarrier planning for 60MHz. As one possible implementation, the subcarriers of the 242-tone DRUs are shown in Tables 4 to 8. It should be understood that the subcarriers of the 242-tone DRUs shown in Tables 4 to 8 are merely examples. Different subcarriers can be designed by combining the features of the 52-tone DRUs, the 13 subcarrier groups, the features satisfied by the 106-tone DRUs, and the features satisfied by the 242-tone DRUs described above; these will not be listed here.

[0791] For any other implementation method or example not described in detail in (1) to (3) above, please refer to other implementation methods or examples.

[0792] This application provides a subcarrier planning (or subcarrier distribution) corresponding to 60MHz. In this subcarrier planning, the subcarriers in each DRU are as uniformly discrete as possible, and the subcarriers of each DRU cover as large a bandwidth range as possible. This not only effectively reduces the PAPR of the field transmitted using the DRU, but also improves the transmit power of each subcarrier. Simultaneously, the greater common divisor of at least two distances is as large as possible; the larger the sampling multiple, the shorter the downsampled data, and the smaller the PAPR, thereby further reducing the PAPR. These distances include the distance between adjacent subcarriers in a 52-tone DRU, the distance between adjacent subcarriers in a 106-tone DRU, or the distance between adjacent subcarriers in a 242-tone DRU.

[0793] This application also provides a communication method, which includes:

[0794] The first device generates some or all of the fields of the PPDU and transmits some or all of the fields of the PPDU on the DRU. Correspondingly, the second device receives some or all of the fields of the PPDU on the DRU and parses some or all of the fields of the PPDU. The details are similar to those above and will not be repeated here.

[0795] The aforementioned DRU is one of the subcarrier plans corresponding to a discrete bandwidth of 60MHz. Refer to Tables 4 to 8 for details on the subcarrier plans corresponding to 60MHz. The following is a detailed explanation.

[0796] As one possible implementation, Table 4 shows the DRU numbers and subcarriers within a discrete bandwidth of 60MHz provided in the embodiments of this application. RU i represents the RU number, and [a:c] indicates that the subcarriers of the RU are from a to c, including a and c themselves.

[0797] Table 4 shows that the subcarriers of 106-tone DRU 1 include the subcarriers of 52-tone DRU 1 and 52-tone DRU 2. For example, the subcarrier indices of 52-tone DRU 1 are [-494, -494+13, -494+13*2, -494+13*3, ..., -494+13*36, 13, 13+13, 13+13*2, ..., 13+13*14], and the subcarrier indices of 52-tone DRU 2 are [-487, -487+13, -487+13*2, -487+13*3, ..., -487+13*36, 20, 20+13, 20+13*2, ..., 20+13*14]. Therefore, the 106-tone DRU... The subcarrier indices of 1 are [-494,-494+13,-494+13*2,-494+13*3,……,-494+13*36,13,13+13,13+13*2,……,13+13*14] and [-487,-487+13,-487+13*2,-487+13*3,……,-487+13*36,20,20+13,20+13*2,……,20+13*14]. The subcarriers of this 106-tone DRU 1 also include [208,215].

[0798] The subcarriers of 106-tone DRU 2 include subcarriers of 52-tone DRU 3 and 52-tone DRU 4. The subcarriers of 106-tone DRU 2 also include [211, 218].

The subcarriers of 106-tone DRU 6 include the subcarriers of 52-tone DRU 11 and 52-tone DRU 12. The subcarriers of 106-tone DRU 6 also include [213, 220].

[0799] In Table 4, the subcarriers of 242-tone DRU 1 include the subcarriers of 106-tone DRU 1 and 106-tone DRU 2. The subcarriers of 242-tone DRU 2 include the subcarriers of 106-tone DRU 3 and 106-tone DRU 4. The subcarriers of 242-tone DRU 3 include the subcarriers of 106-tone DRU 5 and 106-tone DRU 6.

[0800] Therefore, the designed DRU can satisfy the inheritance structure (as shown above, a 106-tone DRU subcarrier includes two 52-tone DRU subcarriers, and a 242-tone DRU subcarrier includes two 106-tone DRU subcarriers), simplifying resource allocation instructions.

[0801] Table 4

[0802] The DRU numbers of the same type in Table 4 can be interchanged, and the subcarrier planning after the interchange is also within the protection scope of the embodiments of this application.

[0803] Optionally, the subcarrier planning corresponding to 60MHz does not include 26-tone DRUs.

[0804] Optionally, the subcarrier planning corresponding to 60MHz includes 26-tone DRUs. In this case, a 52-tone DRU's subcarrier comprises two 26-tone DRU subcarriers. The subcarrier of 52-tone DRU 1 comprises a subcarrier of 26-tone DRU 1 and a subcarrier of 26-tone DRU 2.

The subcarriers of 52-tone DRU 9 include subcarriers of 26-tone DRU 20 and 26-tone DRU 21. The subcarriers of 52-tone DRU 10 include subcarriers of 26-tone DRU 22 and 26-tone DRU 23. The subcarriers of 52-tone DRU 11 include subcarriers of 26-tone DRU 25 and 26-tone DRU 26. The subcarriers of 52-tone DRU 12 include the subcarriers of 26-tone DRU 27 and 26-tone DRU 28. For example, the subcarriers in a 52-tone DRU can be divided into odd-numbered and even-numbered subcarriers. In the two 26-tone DRUs included in this 52-tone DRU, one 26-tone DRU has an odd-numbered subcarrier, and the other 26-tone DRU has an even-numbered subcarrier. The numbering and subcarrier ranges of the 26-tone DRUs are not listed here.

[0805] As another possible implementation, Table 5 shows the DRU numbers and subcarrier ranges within a discrete bandwidth of 60MHz provided in the embodiments of this application. Further details regarding Table 5 are given in Table 4 and will not be elaborated upon here.

[0807] As another possible implementation, Table 6 shows the numbering and subcarrier range of each DRU within a discrete bandwidth of 60MHz provided in the embodiments of this application.

[0808] In Table 6, the subcarriers of 106-tone DRU 1 include subcarriers of 52-tone DRU 1 and 52-tone DRU 2. The subcarriers of 106-tone DRU 1 also include [209, 215].

[0809] For further explanation of Table 6, please refer to Table 4, which will not be elaborated here.

[0810] Table 6

[0811] As another possible implementation, Table 7 shows the DRU numbers and subcarrier ranges within a discrete bandwidth of 60MHz provided in the embodiments of this application. Further explanations regarding Table 7 can be found in Table 4 or Table 6, etc., and will not be detailed here.

[0812] Table 7

[0813] Optionally, the indices of the 60MHz subcarriers in Tables 4 to 7 are [-500:-3,3:253]. The subcarrier plans shown in Tables 4 to 7 are merely examples. Different subcarrier plans can be constructed based on the features satisfied by the 52-tone DRU, 106-tone DRU, and 242-tone DRU described above. The constructed subcarrier plans also fall within the protection scope of the embodiments of this application, and will not be listed here one by one.

[0814] The following example uses a 60MHz subcarrier range of [-253:-3,3:500] to illustrate the subcarrier planning corresponding to 60MHz in the embodiments of this application.

[0815] Since the indices of [-253:-3,3:500] and [-500:-3,3:253] are opposites, the opposite indices of the subcarrier indices of each DRU in the 60MHz subcarrier planning listed above also fall within the protection scope of this application's embodiments. In other words, the inverted indices of the subcarrier indices of each DRU in the 60MHz subcarrier planning listed above also fall within the protection scope of this application's embodiments. Examples are given below.

[0816] As one possible implementation, Table 8 shows the DRU numbers and subcarrier ranges within a discrete bandwidth of 60MHz provided in this embodiment. Further details regarding Table 8 are given above and will not be repeated here. Table 8 is obtained by inverting the indices in Table 4.

[0817] Table 8

[0818] The opposites of the indices in Tables 5 to 7 will not be listed here.

[0819] In a practical implementation, some or all fields of the PPDU can be transmitted on each of the DRUs shown above. Alternatively, some or all fields of the PPDU can be transmitted on some of the DRUs shown above, meaning that only some of the DRUs mentioned above can be used, and it is not necessary to use every type of DRU.

[0820] This application's embodiments design subcarrier planning corresponding to a discrete bandwidth of 60MHz. The subcarriers within each DRU are discontinuous, and can be discretized across a larger bandwidth. By rationally designing the positions of the subcarriers within each DRU, the transmit power of each subcarrier is effectively improved, enabling the transmitter to transmit at a higher power. Furthermore, the discretized subcarriers within each DRU are approximately uniformly distributed, ensuring that the PAPR of some or all fields of the PPDU is relatively small. Simultaneously, for 52-tone DRUs and 106-tone DRUs, which have the same structure (i.e., DRUs of the same type), they can be obtained by shifting another DRU, thus simplifying implementation complexity and facilitating the design of channel estimation sequences.

[0821] For information on the numbering of each DRU and the indexing of the subcarriers within a discrete bandwidth of 60MHz, please refer to Tables 10 to 12 below.

[0839] As another possible implementation, the subcarrier index of the DRU is referenced in Tables 10 to 12, which show the subcarrier index of one of the three 242-tone DRUs.

[0840] The features satisfied by the 52-tone DRU, the 106-tone DRU, or the 242-tone DRU mentioned above are individual embodiments, or they can be combined with each other to form an embodiment.

[0841] The subcarrier indices of the 52-tone DRU, 106-tone DRU, or 242-tone DRU mentioned above are separate embodiments, or they can be combined into one embodiment.

[0842] Figures 7a and 7c are schematic diagrams of simulation results provided in the embodiments of this application. Figure 7a compares the simulation results for a 52-tone DRU, Figure 7b compares the simulation results for a 106-tone DRU, and Figure 7c compares the simulation results for a 242-tone DRU. To facilitate comparison of the impact of different DRU designs on PAPR, 100,000 sets of random BPSK and QPSK data were randomly generated for each DRU size, and the PAPR distribution was statistically analyzed. The cumulative distribution function (CDF) under different schemes was also compared. The cumulative distribution function F(x) is a continuous function, representing the sum of the probabilities of all values ​​greater than x, i.e., F(x) = P(x <= x).

[0843] Figures 7a and 7c show the PAPR of the data field in the PPDU under different types of DRU.

[0844] The subcarrier planning for the comparative schemes in Figures 7a to 7c is shown in Table 9.

[0845] Table 9

[0846] Based on the simulation comparison results, the solution provided in this application embodiment has a smaller average PAPR in both 52-tone DRU and 106-tone DRU, and a similar PAPR in 242-tone DRU.

[0847] This application also provides another subcarrier planning for 60MHz.

[0848] As shown above, the subcarrier planning corresponding to 60MHz includes 12 52-tone DRUs. For a description of these 12 52-tone DRUs, please refer to the above text; details will not be repeated here.

[0849] The 12 subcarrier groups corresponding to the 12 52-tone DRUs are 12 of the following 14 subcarrier groups:

[0850] The index of the subcarriers in the first subcarrier group is [-500:14:-10,4:14:242];

[0851] The index of the subcarriers in the second subcarrier group is [-499:14:-9,5:14:243];

[0852] The index of the subcarriers in the third subcarrier group is [-498:14:-8,6:14:244];

[0853] The index of the subcarriers in the 4th subcarrier group is [-497:14:-7,7:14:245];

[0854] The index of the subcarriers in the 5th subcarrier group is [-496:14:-6,8:14:246];

[0855] The index of the subcarrier in the 6th subcarrier group is [-495:14:-5,9:14:247];

[0856] The index of the subcarrier in the 7th subcarrier group is [-494:14:-4,10:14:248];

[0857] The index of the subcarriers in the 8th subcarrier group is [-493:14:-3,11:14:249];

[0858] The index of the subcarriers in the 9th subcarrier group is [-492:14:-16,12:14:250];

[0859] The index of the subcarriers in the 10th subcarrier group is [-491:14:-15,13:14:251];

[0860] The index of the subcarriers in the 11th subcarrier group is [-490:14:-14,14:14:252];

[0861] The index of the subcarriers in the 12th subcarrier group is [-489:14:-13,15:14:253];

[0862] The index of the subcarriers in the 13th subcarrier group is [-488:14:-12,16:14:240];

[0863] The index of the subcarriers in the 14th subcarrier group is [-487:14:-11,3:14:241].

[0864] As shown above, with the last 20MHz in the 80MHz range being punctured, the subcarrier index for the 60MHz range is [-500:-3,3:253]. To ensure that there is at most one subcarrier within each 1MHz range and that the subcarrier distribution is as uniform as possible, one subcarrier is selected every 14 consecutive subcarriers, thus dividing the available subcarriers into the aforementioned 14 subcarrier groups.

[0865] Any one of the 14 subcarrier groups mentioned above can guarantee that there is only one subcarrier within each 1MHz. Each subcarrier group contains at least 52 subcarriers, and all subcarriers are approximately evenly distributed. Therefore, 52 subcarriers can be selected from any of the above subcarrier groups to form a 52-tone DRU.

[0866] As one possible implementation, by combining the features of the 52-tone DRU described above, and any 12 subcarrier groups from the 14 subcarrier groups described above, the subcarriers of the 52-tone DRU can be constructed. The subcarriers of the 52-tone DRU constructed in this way fall within the protection scope of the embodiments of this application. Optionally, when constructing the 52-tone DRU, 12 subcarrier groups other than the k-th and k+7-th subcarrier groups can be selected from the 14 subcarrier groups. k = 1, 2, 3, 4, 5, 6, or 7. This ensures that the subcarriers of the 106-tone DRU obtained by merging the 52-tone DRUs are distributed as evenly as possible.

[0867] As an example, combining the features of the 52-tone DRU described above, and the 1st to 6th, 8th to 13th subcarrier groups out of the 14 subcarrier groups described above, the subcarrier index of the 52-tone DRU is shown in Table 10 as one possible implementation.

[0868] As one possible implementation, by combining the 12 features satisfied by the 52-tone DRU described above, the 14 subcarrier groups, and the 6 features satisfied by the 106-tone DRU described above, subcarriers of the 106-tone DRU can be constructed. For example, the index of the subcarriers of the 106-tone DRU is shown in Table 10.

[0869] Optionally, as shown above, the subcarrier of the 106-tone DRU i also includes two subcarriers in the subcarrier group corresponding to the 52-tone DRU m, excluding the 52 subcarriers in the 52-tone DRU m. Optionally, the subcarrier of the 106-tone DRU i also includes two subcarriers in the subcarrier group corresponding to the 52-tone DRU n, excluding the 52 subcarriers in the 52-tone DRU n. Optionally, the subcarrier of the 106-tone DRU i also includes one subcarrier in the subcarrier group corresponding to the 52-tone DRU m, excluding the 52 subcarriers in the 52-tone DRU m, and the subcarrier of the 106-tone DRU i also includes one subcarrier in the subcarrier group corresponding to the 52-tone DRU n, excluding the 52 subcarriers in the 52-tone DRU n. The relationship between the 52-tone DRU and the 106-tone DRU is described above and will not be elaborated here.

[0870] In Table 10, each pair of different 52-tone DRUs among the above 12 52-tone DRUs is merged, and an additional subcarrier is selected in the subcarrier group corresponding to each 52-tone DRU, thereby forming 6 106-tone subcarriers.

[0871] Optionally, any two 106-tone DRUs can satisfy a translation relationship. For an explanation of the relationship between 52-tone DRUs and 106-tone DRUs, please refer to the above text; it will not be elaborated upon here.

[0872] As one possible implementation, by combining the three characteristics of a 242-tone DRU described above, subcarriers of a 242-tone DRU can be constructed. For example, the index of subcarriers of a 242-tone DRU is shown in Table 10.

[0873] Optionally, as shown above, the subcarriers of 242-tone DRU i also include some subcarriers from the four subcarrier groups corresponding to 106-tone DRU m and 106-tone DRU n. Optionally, the subcarriers of 242-tone DRU i also include some subcarriers from one of the 14 subcarrier groups, excluding the 12 subcarrier groups. Optionally, besides the 212 subcarriers of 106-tone DRU m and 106-tone DRU n, a portion of the remaining 30 subcarriers of 242-tone DRU i are contained in the four subcarrier groups corresponding to these two 106-tone DRUs, and the remaining portion of the remaining 30 subcarriers is contained in one of the 14 subcarrier groups, excluding the 12 subcarrier groups. The aforementioned 12 subcarrier groups refer to the 12 subcarrier groups corresponding to the 12 52-tone DRUs.

[0874] In Table 10, each pair of 106-tone DRUs is merged, and subcarriers are selected from two of the 14 subcarrier groups other than the 12 subcarrier groups corresponding to the 12 52-tone DRUs, thus forming the subcarriers of a 242-tone DRU. The relationship between 242-tone DRUs and 52-tone DRUs (or 106-tone DRUs) is explained above and will not be elaborated here.

[0875] Table 10 shows the DRU numbers and subcarrier indices within a discrete bandwidth of 60MHz provided in the embodiments of this application.

[0876] Table 10

[0877] For further explanation of Table 10, please refer to the above text; it will not be elaborated here.

[0878] As another example, combining the features of the 52-tone DRU described above, and the 2nd to 7th subcarrier groups, and the 9th to 14th subcarrier groups in the 14 subcarrier groups described above, the subcarrier index of the 52-tone DRU is shown in Table 11 as one possible implementation.

[0879] As one possible implementation, by combining the 12 features satisfied by the 52-tone DRU described above, and the 6 features satisfied by the 106-tone DRU described above, subcarriers of the 106-tone DRU can be constructed. For example, the index of the subcarriers of the 106-tone DRU is shown in Table 11.

[0880] As one possible implementation, by combining the three characteristics of a 242-tone DRU described above, subcarriers of a 242-tone DRU can be constructed. For example, the index of subcarriers of a 242-tone DRU is shown in Table 11.

[0881] Table 11 shows the DRU numbers and subcarrier indices within a discrete bandwidth of 60MHz provided in the embodiments of this application.

[0882] Table 11

[0883] For further explanation of Table 11, please refer to the above text, and it will not be elaborated here.

[0884] Figures 11a to 11c are schematic diagrams of simulation results provided in the embodiments of this application. Figure 11a shows a comparison of simulation results for a 52-tone DRU, Figure 11b shows a comparison of simulation results for a 106-tone DRU, and Figure 11c shows a comparison of simulation results for a 242-tone DRU. Further explanations regarding Figures 11a to 11c are provided in the descriptions of Figures 7a to 7c, and will not be detailed here.

[0885] Based on the simulation comparison results, the solution provided in this application embodiment has a smaller average PAPR in both 52-tone DRU and 106-tone DRU, and a similar PAPR in 242-tone DRU.

[0886] This application also provides another subcarrier planning method corresponding to 60MHz.

[0887] As shown above, the subcarrier planning corresponding to 60MHz includes 12 52-tone DRUs. For a description of these 12 52-tone DRUs, please refer to the above text; details will not be repeated here.

[0888] The 12 subcarrier groups corresponding to the 12 52-tone DRUs are:

[0889] [-500:12:-8,4:12:244];

[0890] [-499:12:-7,5:12:245];

[0891] [-498:12:-6,6:12:246];

[0892] [-497:12:-5,7:12:247];

[0893] [-496:12:-4,8:12:248];

[0894] [-495:12:-3,9:12:249];

[0895] [-494:12:-14,10:12:250];

[0896] [-493:12:-13,11:12:251];

[0897] [-492:12:-12,12:12:252];

[0898] [-491:12:-11,13:12:253];

[0899] [-490:12:-10,14:12:242];

[0900] [-489:12:-9,3:12:243].

[0901] As shown above, with the last 20MHz in the 80MHz range being punctured, the index of the 60MHz subcarrier is [-500:-3,3:253]. To ensure that different types of DRUs have low PAPR, the subcarriers contained in different types of DRUs need to be distributed as evenly as possible. Therefore, one subcarrier is selected every 12 consecutive subcarriers, thus dividing the available subcarriers into the aforementioned 12 subcarrier groups.

[0902] Each of the above subcarrier groups contains at least 52 subcarriers, and all subcarriers are approximately evenly distributed. Therefore, 52 subcarriers can be selected from any of the above subcarrier groups to form a 52-tone DRU.

[0903] To ensure sufficient DC subcarrier guard interval, subcarriers near subcarriers with index 0 are not selected, and boundary subcarriers are also avoided as much as possible. Furthermore, since a 52-tone DRU cannot achieve maximum power gain, each 52-tone DRU can be split into two 26-tone DRUs to consider maximum power gain. To ensure that the split 26-tone DRUs have uniformly distributed subcarrier indices, an even number of subcarriers with negative indices and an even number of subcarriers with positive indices can be selected from each subcarrier group. The distance between the largest negative subcarrier index and the smallest positive subcarrier index among the selected subcarrier indices must be an odd multiple of 12.

[0904] As one possible implementation, combining the features of the 52-tone DRU described above, and the 12 subcarrier groups described above, the subcarriers of the 52-tone DRU can be constructed. 52 subcarriers are selected from each subcarrier group to construct the 52-tone DRU. Different selection methods result in different subcarriers for the final 52-tone DRU, all of which are within the protection scope of this application's embodiments. For example, the 52-tone DRU may satisfy a translation relationship; the index difference between adjacent subcarriers may be an odd multiple of 12; or each 52-tone DRU may have an even number of subcarriers with positive indices and an even number of subcarriers with negative indices. Table 12 exemplarily shows the subcarrier indices of the 52-tone DRU.

[0905] As one possible implementation, the aforementioned 12 52-tone DRUs can be divided into 24 26-tone DRUs. As shown above, the subcarriers in a 52-tone DRU can be divided into odd-numbered subcarriers (i.e., the 1st, 3rd, 5th, 7th..., 51st subcarriers in the 52-tone DRU) and even-numbered subcarriers (i.e., the 2nd, 4th, 6th, 8th..., 52nd subcarriers in the 52-tone DRU). The subcarriers of one of the two 26-tone DRUs included in this 52-tone DRU are odd-numbered subcarriers, and the subcarriers of the other 26-tone DRU are even-numbered subcarriers.

[0906] Table 12 provides an example of the subcarrier indices for a 26-tone DRU. The DRU numbers shown in Table 12 are merely illustrative; further explanation of the numbering can be found above and will not be repeated here.

[0907] Optionally, the subcarrier planning corresponding to 60MHz includes a 26-tone DRU. Optionally, the subcarrier planning corresponding to 60MHz does not include a 26-tone DRU.

[0908] Table 12

[0909] Optionally, the index difference between adjacent subcarriers in a 52-tone DRU is an integer multiple of 12, which may prevent the 52-tone DRU from achieving its maximum power gain. Therefore, the 52-tone DRU can be split into two 26-tone DRUs, making the 26-tone DRUs usable.

[0910] As one possible implementation, by combining the 12 features satisfied by the 52-tone DRU described above, and the 6 features satisfied by the 106-tone DRU described above, subcarriers of the 106-tone DRU can be constructed. For example, the index of the subcarriers of the 106-tone DRU is shown in Table 12.

[0911] Optionally, as shown above, the subcarriers of the 106-tone DRU i also include two subcarriers in the subcarrier group corresponding to the 52-tone DRU m, excluding the 52 subcarriers in the 52-tone DRU m. Optionally, the subcarriers of the 106-tone DRU i also include two subcarriers in the subcarrier group corresponding to the 52-tone DRU n, excluding the 52 subcarriers in the 52-tone DRU n. The relationship between the 52-tone DRU and the 106-tone DRU is explained above and will not be detailed here.

[0912] As one possible implementation, by combining the three characteristics of a 242-tone DRU described above, subcarriers of a 242-tone DRU can be constructed. For example, the index of subcarriers of a 242-tone DRU is shown in Table 12.

[0913] Optionally, as shown above, the subcarriers of 242-tone DRU i also include subcarriers other than the 212 subcarriers included in the four subcarrier groups corresponding to 106-tone DRU m and 106-tone DRU n. For an explanation of the relationship between 242-tone DRU and 52-tone DRU (or 106-tone DRU), please refer to the above text; it will not be elaborated upon here.

[0914] Figures 12a to 12d are schematic diagrams of simulation results provided in the embodiments of this application. Figure 12a shows a comparison of simulation results for a 26-tone DRU, Figure 12b shows a comparison of simulation results for a 52-tone DRU, Figure 12c shows a comparison of simulation results for a 106-tone DRU, and Figure 12d shows a comparison of simulation results for a 242-tone DRU. Further explanations of Figures 12a to 12d are given in Figures 7a to 7c and will not be detailed here.

[0915] Based on the simulation comparison results, the solution provided in this application embodiment has a smaller average PAPR in both 52-tone DRU and 106-tone DRU, and a similar PAPR in 242-tone DRU.

In actual implementation, all or some modules can be integrated into one physical entity, or they can be distributed across different physical entities. Furthermore, the above-mentioned functional modules can be implemented in hardware, software, or a combination of both.

The connection methods between other components are merely illustrative and not intended to be limiting. The bus can be an address bus, data bus, control bus, etc. For ease of illustration, only one thick line is used in Figure 9, but this does not indicate that there is only one bus or one type of bus.

The memory 930 is primarily used for storing software programs and data. The transceiver 910 may include control circuitry and an antenna. The control circuitry is primarily used for converting baseband signals to radio frequency signals and processing radio frequency signals. The antenna is primarily used for transmitting and receiving radio frequency signals in the form of electromagnetic waves. Input / output devices, such as touchscreens, displays, and keyboards, are primarily used for receiving user input data and outputting data to the user.

[0942] When the communication device is powered on, the processor 920 can read the software program in the memory 930, interpret and execute the instructions of the software program, and process the data of the software program. When data needs to be transmitted wirelessly, the processor 920 performs baseband processing on the data to be transmitted and outputs the baseband signal to the radio frequency (RF) circuit. The RF circuit processes the baseband signal and transmits the RF signal outward in the form of electromagnetic waves through the antenna. When data is sent to the communication device, the RF circuit receives the RF signal through the antenna, converts the RF signal into a baseband signal, and outputs the baseband signal to the processor 920. The processor 920 converts the baseband signal into data and processes the data.

[0943] In another implementation, the radio frequency circuitry and antenna can be set up independently of the processor performing baseband processing. For example, in a distributed scenario, the radio frequency circuitry and antenna can be arranged remotely, independent of the communication device.
