Description

Communication method, device and system

[0001] This application claims priority to the Chinese patent application with application number 202410246296.9 filed with the State Intellectual Property Office of China on March 4, 2024, and priority to the Chinese patent application with the invention name “Communication Method, Device and System”, all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of wireless communication technology, and in particular to a communication method, device, and system. Background Art

[0003] The European Telecommunications Standards Institute (ETSI) has issued regulations for the 6 GHz spectrum, limiting the maximum transmit power to 23 dBm (decibel-milliwatts) and the maximum power spectral density to 10 dBm / MHz (decibel-milliwatts / megahertz). The US Federal Communications Commission has also issued regulations for the 6 GHz spectrum, defining a low-power indoor (LPI) communication mode with strict limits on maximum transmit power and maximum frequency spectral density. For access points (APs), the maximum transmit power is limited to 30 dBm and the maximum power spectral density is 5 dBm / MHz. For stations (STAs), the maximum transmit power is limited to 24 dBm and the maximum power spectral density is -1 dBm / MHz. A device's transmit power is subject to both maximum power and maximum power spectral density limits: the transmit power cannot exceed the maximum power value, and the transmit power spectral density (PSD) cannot exceed the maximum power spectral density. Compared to maximum power, maximum power spectral density (PSD) limits are more stringent, and the maximum transmit power is generally more restricted by PSD. For a station, the transmit power reaches the specified maximum power limit only when the bandwidth is 320 MHz. When the bandwidth is less than 320 MHz, the station can only transmit at a lower power (here, lower than the specified maximum power) due to the PSD limit.

[0004] Based on this, distributed resource unit (DRU) technology was proposed to improve transmit power. The basic idea of ​​DRU is to disperse the consecutive subcarriers within a resource unit (RU) over the widest possible bandwidth, reducing the number of subcarriers within 1MHz. This increases the transmit power of each subcarrier and, in turn, the total transmit power.

[0005] Therefore, how to design a specific subcarrier plan (toneplan) has become an urgent problem to be solved. Summary of the Invention

[0666] In the embodiment of the present application, by satisfying the above conditions, the 996-tone DRU can achieve a larger power amplification factor, thereby improving the transmission power of the communication device, and can also ensure that the two 996-tone DRUs achieve an overall translation relationship, which is beneficial to the storage of indexes and the simplification of sequence design.

[0930] To facilitate understanding of the technical solution of the present application, the present application will be further described below with reference to the accompanying drawings.

[0931] The terms "first" and "second" in the specification, claims, and drawings of this application are used only to distinguish different objects and are not used to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to the process, method, product, or device.

[0932] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it refer to independent or alternative embodiments that are mutually exclusive of other embodiments. It will be understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0933] In this application, "at least one (item)" means one or more, "more than one" means two or more, "at least two (items)" means two or three and more than three, and "and / or" is used to describe the association relationship of associated objects, indicating that three relationships can exist. For example, "A and / or B" can mean: only A exists, only B exists, and A and B exist at the same time, where A and B can be singular or plural. "Or" means that two relationships can exist, such as only A exists, only B exists; when A and B are not mutually exclusive, it can also mean that three relationships exist, such as only A exists, only B exists, and A and B exist at the same time. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items. For example, at least one 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".

[0934] In this application, "sending" and "receiving" indicate the direction of signal transmission. For example, "sending information to XX" can be understood as the destination of the information is XX, which can include direct sending through the air interface, and also include indirect sending through the air interface by other units or modules. "Receiving information from YY" can be understood as the source of the information is YY, which can include direct receiving from YY through the air interface, and also include indirect receiving from YY through the air interface from other units or modules. "Sending" can also be understood as the "output" of the chip interface, and "receiving" can also be understood as the "input" of the chip interface. In other words, sending and receiving can be carried out between devices, for example, between network devices and terminal devices, or can be carried out within a device, for example, sending or receiving between components, modules, chips, software modules or hardware modules within the device through a bus, trace or interface.

[0935] The embodiments of the present application provide a communication method, device and system, which improve the subcarrier planning corresponding to 160MHz, and each DRU under the subcarrier planning can achieve a larger power amplification factor.

[0936] The following introduces the system involved in the embodiments of the present application.

[0937] The technical solutions provided in the embodiments of the present application can be applied to wireless local area network (WLAN) systems, such as Wi-Fi, etc. The technical solutions provided in the embodiments of the present application can be applied to the Institute of Electrical and Electronics Engineers IEEE 802.11 series protocols (or standards), such as the 802.11be protocol, the 802.11bn protocol (or Wi-Fi 8, also known as ultra high reliability (UHR) or ultra high reliability and throughput (UHRT), etc.) or the next generation of the 802.11bn protocol or the protocol that supports ambient power (AMP), etc., which are not listed one by one. The technical solutions provided in the embodiments of the present application can also be applied to wireless personal area networks (WPAN) based on millimeter wave (MMW) and ultra wideband (UWB) technologies, etc. The technical solutions provided in the embodiments of the present application can be applied to the IEEE802.15 series of protocols, such as the 802.15.4a protocol, the 802.15.4z protocol or the 802.15.4ab protocol, or a future generation of UWB WPAN protocols, etc., which are not listed one by one. The technical solutions provided in the embodiments of the present application can also be applied to the spark link or nearlink standard protocol. The technical solutions provided in the embodiments of the present application can also be applied to the following communication systems, for example, the Internet of Things (IoT) system, vehicle-to-everything (V2X, X can represent anything), device-to-device (D2D), narrowband Internet of Things (NB-IoT) system, long term evolution (LTE) system, fifth-generation (5G) communication system, and new communication systems emerging in future communication development. For example, the V2X may include: vehicle to vehicle (V2V), vehicle to infrastructure (V2I), vehicle to pedestrian (V2P) or vehicle to network (V2N) communication, etc.

[0938] WLAN systems can provide high-speed and 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, corporate offices, sports stadiums and exhibition halls, concert halls, hotel rooms, dormitories, wards, classrooms, supermarkets, squares, streets, production workshops and warehouses, etc. Of course, devices that support WLAN communication or perception (such as access points or stations) can be sensor nodes in smart cities (such as smart water meters, smart electricity meters, and smart air detection nodes), smart devices in smart homes (such as smart cameras, projectors, displays, TVs, speakers, refrigerators, washing machines, etc.), nodes in the Internet of Things, entertainment terminals (such as wearable devices such as augmented reality (AR) and virtual reality (VR)), smart devices in smart offices (such as printers, projectors, loudspeakers, speakers, etc.), Internet of Vehicles devices, infrastructure in daily life scenarios (such as vending machines, self-service navigation counters in supermarkets, self-service checkout equipment, self-service ordering machines, etc.), and equipment in large sports and music venues.

[0939] Although the embodiments of the present application primarily use WLAN as an example, particularly networks based on the IEEE 802.11 standard, the various aspects of the embodiments of the present application can be extended to other networks based on various standards or protocols, such as Bluetooth, high-performance wireless LAN (HIPERLAN) (a wireless standard similar to the IEEE 802.11 standard), wide area network (WAN), or other networks now known or developed in the future.

[0940] In one possible implementation, the method provided in the embodiment of the present application may be implemented by a communication device in a communication system. For example, the communication device may be an access point (AP) or a station (STA).

[0941] An AP is a device with wireless communication capabilities that supports communication, perception, or energy transmission using WLAN protocols. It has the ability to communicate, perceive, or transmit energy with other devices in a WLAN network (such as non-access point stations (non-AP STAs) or other access points). Of course, it can also have the ability to communicate, perceive, or transmit energy with other devices. Alternatively, an access point is equivalent to a bridge connecting a wired network and a wireless network. Its main function is 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). The device with wireless communication capabilities can be a complete device, or it can be a chip, processing system, or functional module installed in the complete device. The device in which these chips, processing systems, or functional modules are installed can implement the methods and functions of the embodiments of the present application under the control of the chips, processing systems, or functional modules. The AP in the embodiments of the present application is a device that provides services for non-AP STAs and can support 802.11 series protocols or subsequent protocols. For example, an access point can be an access point for a terminal (such as a mobile phone) to enter a wired (or wireless) network. It is mainly deployed in homes, buildings, and campuses, with a typical coverage radius of tens to hundreds of meters. Of course, it can also be deployed outdoors. For another example, an AP can be a communication entity such as a communication server, router, switch, or bridge; an AP can include various forms of macro base stations, micro base stations, and relay stations. Of course, an AP can also be a chip, processing system, or module in any of the above-mentioned devices, thereby implementing the methods and functions of the embodiments of the present application.

[0942] A STA is a device with wireless communication capabilities that supports communication, sensing, or energy transmission using the WLAN protocol and has the ability to communicate, sense, or transmit energy with other non-AP STAs or access points in the WLAN network. In a WLAN system, a station can be referred to as a non-access point station (non-AP STA). For example, a STA is any user communication device that allows a user to communicate, sense, or transmit energy with an AP and thereby communicate with the WLAN. The device with wireless communication capabilities can be a complete device, or a chip, processing system, or functional module installed in the complete device. Devices equipped with these chips, processing systems, or functional modules can implement the methods and functions of the embodiments of the present application under the control of the chip, processing system, or functional module. For example, a STA can be a wireless communication chip, a wireless sensor, or a wireless communication terminal, and can also be referred to as a user. For another example, a STA can be a mobile phone that supports Wi-Fi communication capabilities, a tablet that supports Wi-Fi communication capabilities, a set-top box that supports Wi-Fi communication capabilities, a smart TV that supports Wi-Fi communication capabilities, a smart wearable device that supports Wi-Fi communication capabilities, an in-vehicle communication device that supports Wi-Fi communication capabilities, and a computer that supports Wi-Fi communication capabilities. Of course, STA can also be a chip, processing system, or module in the various forms of devices mentioned above, so as to implement the methods and functions of the embodiments of the present application.

[0943] Exemplarily, the communication system to which the method provided in the embodiment of the present application can be applied may include access points and stations. For example, the embodiment of the present application may be applicable to scenarios of communication or perception between AP and STA, between AP and AP, or between STA and STA in a WLAN, and the embodiment of the present application is not limited to this. Optionally, the AP may communicate or perceive with a single STA, or the AP may communicate or perceive with multiple STAs at the same time. Specifically, the communication or perception between the AP and multiple STAs can be divided into downlink transmission in which the AP sends signals to multiple STAs at the same time, and uplink transmission in which multiple STAs send signals to the AP. Among them, the WLAN communication protocol can be supported between the AP and the STA, between the AP and the AP, and between the STA and the STA. The communication protocol may include a protocol of the IEEE802.11 series, such as the 802.11bn protocol, and of course, it is also applicable to protocols after 802.11bn.

[0949] The following introduces the terms or nouns involved in the embodiments of this application.

[0950] 1. Resource unit (RU)-based subcarrier planning (toneplan)

[0951] As an example, when the bandwidth is 20 MHz, the entire bandwidth (i.e., 20 MHz) can be composed of a 242-tone RU, or various combinations of 26-tone RUs, 52-tone RUs, and 106-tone RUs. Figure 2a is a schematic diagram of the 20 MHz subcarrier distribution and RU distribution provided in an embodiment of the present application. As shown in Figure 2a, 20 MHz can include 9 26-tone RUs, or 4 52-tone RUs, or 2 106-tone RUs, or 1 242-tone RU.

[0952] 26-tone-RU is an RU including 26 subcarriers, 52-tone RU is an RU including 52 subcarriers, 106-tone RU is an RU including 106 subcarriers, 242-tone RU is an RU including 242 subcarriers, and so on. Each RU may include data subcarriers and pilot subcarriers. For example, the data subcarrier can be used to carry data information, and the pilot subcarrier can be used for estimating phase deviation and / or frequency deviation, etc. In addition to RU, the above-mentioned 20MHz bandwidth may also include at least one of the following: one or more guard subcarriers, one or more null subcarriers, and one or more direct current (DC) subcarriers. For the subcarrier range included in each RU, please refer to the relevant standards or protocols, which will not be described in detail here. The description of RU or subcarrier here also applies to the other bandwidths shown below, which will not be repeated here. The description of subcarrier here also applies to the description of DRU below, which will not be described in detail below.

[0953] As another example, when the bandwidth is 40 MHz, the entire bandwidth (i.e., 40 MHz) can consist of a single 484-tone RU, or various combinations of 26-tone RUs, 52-tone RUs, 106-tone RUs, and 242-tone RUs. The entire bandwidth is roughly equivalent to a replication of the 20 MHz subcarrier plan. As shown in Figure 2b, 40 MHz can include 18 26-tone RUs, or 8 52-tone RUs, or 4 106-tone RUs, or 2 242-tone RUs, or 1 484-tone RU.

[0954] As another example, when the bandwidth is 80 MHz, the entire bandwidth (i.e., 80 MHz) can consist of a full 996-tone RU, or various combinations of 26-tone RUs, 52-tone RUs, 106-tone RUs, 242-tone RUs, and 484-tone RUs. As shown in Figure 2c, 80 MHz can include 36 26-tone RUs, 16 52-tone RUs, 8 106-tone RUs, 4 242-tone RUs, 2 484-tone RUs, or 1 996-tone RU. 484L and 484R represent the left and right halves of a 484-tone RU, respectively containing 242 subcarriers, and are another representation of 484+5DC. For example, if the subcarrier range of a 484-tone RU is [-500:-12], "484L" is the low-frequency portion relative to the frequency center of the 484-tone RU, that is, [-500:-259], and "484R" is the high-frequency portion relative to the frequency center of the 484-tone RU, that is, [-253:-12]. Similarly, if the subcarrier range of a 484-tone RU is [12:500], "484L" is [12:253], and "484R" is [259:500]. These are not listed here.

[0955] In this application, [a:b] can refer to all integers from a to b (a and b are also integers), that is, a, (a+1), (a+2), (a+3), ..., b; this will not be repeated below. For example, [259:500] means 259, 260, 261, 262, ..., 498, 499, 500. For another example, [-500:-259] means -500, -499, -498, -497, ..., -260, -259.

[0956] As another example, when the bandwidth is 160 MHz, the entire bandwidth can be viewed as a replication of two 80 MHz subcarrier distributions. For example, the entire bandwidth can consist of a 2*996-tone RU, or various combinations of 26-tone RU, 52-tone RU, 106-tone RU, 242-tone RU, 484-tone RU, and 996-tone RU. When the bandwidth is 320 MHz, the entire bandwidth can be viewed as a replication of four 80 MHz subcarrier distributions. These examples are not listed here.

[0957] In the above subcarrier planning, with 242-tone RU (i.e. 20MHz) as the unit, the leftmost of Figure 2a to Figure 2c can be the lowest frequency, and the rightmost of Figure 2a to Figure 2c can be the highest frequency. From left to right, the 242-tone RU can be numbered: the first (1st), the second (2 nd ),…, the sixteenth (16 th Taking a 320MHz bandwidth as an example, the data field in a radio frame can occupy up to 16 242-tone RUs. That is, in the data field, there can be a maximum of 16 242-tone RUs corresponding to 16 20MHz channels in ascending frequency order.

[0958] Generally speaking, a STA can be allocated multiple RUs, meaning that multiple RUs can be combined and allocated to a single STA. Therefore, the 802.11be standard supports multiple resource units (MRUs). In other words, in addition to the types of RUs mentioned above, the 802.11be standard also includes several MRUs. For example, a 52-tone RU and a 26-tone RU form a 52+26-tone MRU. Another example is a 106-tone RU and a 26-tone RU form a 106+26-tone MRU. Another example is a 996-tone RU and a 484-tone RU form a 996+484-tone MRU. Another example is two 996-tone RUs and a 484-tone RU form a 2*996+484-tone MRU. Another example is three 996-tone RUs form a 3*996-tone MRU. For another example, three 996-tone RUs and one 484-tone RU form a 3*996+484-tone MRU. The symbol "*" in this application means "multiply" or "multiply by".

[0959] At the bandwidth level, when the subcarrier spacing is 78.125 kHz, a 26-tone RU corresponds to approximately 2 MHz (i.e., 26 * 78.125 kHz = 2031.25 kHz ≈ 2 MHz), a 52-tone RU corresponds to approximately 4 MHz, a 106-tone RU corresponds to approximately 8 MHz, and a 242-tone RU corresponds to approximately 20 MHz. Other RU sizes can be inferred by addition or multiplication, and this application will not elaborate on them.

[0960] The above RU can be called a regular RU (rRU). This regular RU has a smaller bandwidth and lower transmit power than a distributed RU. The "lower" shown here is relative to the distributed RU. For example, the transmit power of a distributed RU can be further increased compared to a regular RU.

[0961] 2. Uplink multi-user transmission

[0962] Uplink multi-user transmission is an important technology. See Figure 3a, which is a schematic diagram of the uplink multi-user transmission process provided by an embodiment of the present application. As shown in Figure 3a, the uplink multi-user transmission process may include: the AP sends a trigger frame to trigger uplink multi-user transmission, and the trigger frame carries the identifier information and resource allocation information of one or more sites; after receiving the trigger frame, each site uses a trigger-based physical layer protocol data unit (TB PPDU) to send an uplink data frame on the allocated resource unit (RU), and receives an acknowledgment (block acknowledgement, BA) frame sent by the AP after a short inter-frame space (SIFS).

[0963] In one possible implementation, the trigger frame may include but is not limited to a common information field and a user information list field. The common information field may contain common information that all STAs scheduled by the trigger frame need to read. In 802.11be, the user information list field of the trigger frame may include but is not limited to one or more EHT variant user information fields (EHTvariant User Info field). An EHT variant user information field may contain information that an EHT STA needs to read. Referring to Figure 3b, Figure 3b is a schematic diagram of the frame format of the EHT variant user information field provided in an embodiment of the present application. As shown in Figure 3b, the EHT variant user information field includes but is not limited to a resource unit allocation subfield (RU Allocation subfield) and a master-slave 160 subfield (PS160 subfield).

[0964] Generally speaking, the RU or MRU allocated to a STA can be indicated by the following subfields: the RU Allocation subfield, the Master-Slave 160 subfield (PS160 subfield), the Uplink Bandwidth subfield (UL BW subfield) in the Common Information Field, or the Uplink Bandwidth Extension subfield (UL BW extension subfield) in the Special User Information Field. In the Common Information Field, B55 indicates whether a Special User Information field is present in the User Information Field. For an EHT TB PPDU, its bandwidth is determined by both the UL BW subfield and the UL BW Extension subfield in the Special User Information Field.

[0965] Table 1 shows the mapping between bit B0 in the RU Allocation subfield, bits B7 to B1 in the RU Allocation subfield, the PS160 subfield, and the RU and MRU. The bandwidth is determined by the UL BW subfield and the UL BW Extension subfield. Table 1 shows the interpretation of the RU Allocation subfield and the PS160 subfield in the 802.11be trigger frame.

[0966] Table 1

[0967] In one possible implementation, N in Table 1 can be obtained by the formula N=2*X1+X0. The values ​​of X1 and X0 can be found in Table 2 below, which shows a lookup table for X1 and N.

[0968] Table 2

[0969] In the above Table 2, P80 represents a primary 80 MHz channel, S80 represents a secondary 80 MHz channel, and S160 represents a secondary 160 MHz channel.

[0970] The configurations in Table 2 above refer to the order of P80, S80, and S160 in absolute frequency, representing the order from low to high frequency from left to right. For example, [P80 S80] indicates that the primary 80 MHz channel is the first 80 MHz channel in ascending order, and the secondary 80 MHz channel is the second 80 MHz channel in ascending order. Alternatively, [P80 S80] indicates that the primary 80 MHz channel is the lower 80 MHz channel, and the secondary 80 MHz channel is the upper 80 MHz channel. For another example, [S80 P80 S160] indicates that the secondary 80 MHz channel is the lower 80 MHz channel within the lower 160 MHz channels, the primary 80 MHz channel is the upper 80 MHz channel within the lower 160 MHz channels, and the secondary 160 MHz channel is the upper 160 MHz channel.

[0971] 3. Distributed resource units

[0972] Recently, the US Federal Communications Commission (FCC) issued regulations regarding the 6 GHz spectrum, defining a low-power indoor (LPI) communication mode with strict limits on maximum transmit power and maximum frequency spectral density. For example, for stations (STAs), the maximum power is 24 dBm, and the maximum power spectral density is -1 dBm / MHz. A device's transmit power is subject to both maximum power and maximum power spectral density limits. First, the transmit power cannot exceed the maximum power value, and the transmitted power spectral density cannot exceed the maximum power spectral density. Compared to maximum power, the maximum power spectral density limit is more stringent, and the maximum allowable transmit power is generally more limited by the power spectral density. For stations, the regulatory maximum power limit is only reached when the bandwidth reaches the maximum of 320 MHz. Below this bandwidth, lower transmit powers are required due to the maximum power spectral density limit. On June 30, 2021, Europe also issued regulations for the 6 GHz spectrum, targeting LPI communication modes, such as a maximum power of 23 dBm and a maximum power spectral density of 10 dBm / MHz. When the bandwidth does not exceed 20 MHz, the transmit power of the AP / STA is mainly limited by the power spectral density. When the bandwidth is greater than 20 MHz, the transmit power of the AP / STA is mainly limited by the maximum power.

[0973] Due to limited power spectral density, the limited number of subcarriers (such as a 26-tone RU) can be dispersed across a wider bandwidth, that is, across more subcarriers (such as the odd-numbered subcarriers of two 26-tone RUs), to increase transmit power. This is known as discrete RU, or distributed RU. This is commonly used in uplink multi-user transmission. By interleaving discrete RUs across multiple users, the transmit power of each user can be increased within a certain bandwidth. It should be noted that the maximum power spectral density is limited to a transmit power of no more than x mW per 1 MHz. Considering a carrier spacing of 78.125 kHz, 1 MHz contains 12.8 (approximately 13) subcarriers. Since the average power of each subcarrier is the same during a transmission, the maximum number of subcarriers carrying a signal over any 13 consecutive subcarriers determines the average power per subcarrier, and thus the transmit power. For example, with a 20 MHz bandwidth (242 subcarriers in total), of the 13 consecutive subcarriers, at most 5 subcarriers carry signals. Therefore, the average power per subcarrier is x(mw) / 5. Considering that there are 26 subcarriers carrying signals, the total transmit power is x(mw) / 5*26.

[0974] The meta-DRU in the present application includes multiple subcarriers that are discrete in the frequency domain, or multiple subcarriers with discrete indexes (or index values), or multiple subcarriers with non-continuous indexes. The multiple discrete subcarriers can be partially discrete or completely discrete. For example, the multiple discrete subcarriers can include a part of subcarriers that are continuous in frequency, and a part of subcarriers that are discontinuous in frequency. For another example, the multiple discrete subcarriers can also be completely discontinuous in frequency. The "continuous in frequency" shown above can also be referred to as the subcarrier indexes being continuous, and "discontinuous in frequency" can also be referred to as the subcarrier indexes being discontinuous. In the present application, "distributed RU" and "DRU" or "discrete RU" can be used interchangeably. It should also be understood that the DRU mentioned in the present application refers to an RU with discrete subcarriers in the frequency domain, that is, the RU with this feature is referred to as a distributed RU or discrete RU in the present application, but in practice, the RU with this feature can also have other names, which are not limited in the present application.

[0975] In this application, a continuous RU refers to an RU consisting of multiple continuous subcarriers, or a continuous RU consists of two groups of continuous subcarrier groups, where the multiple subcarriers included in each group of continuous subcarrier groups are continuous, and the two groups of continuous subcarrier groups are separated only by protected subcarriers, null subcarriers, or DC subcarriers. Of course, the continuous RU can also be called by other names, such as regular RU (rRU). "Continuous RU" and "regular RU" can be used interchangeably, and this application does not limit the name of the continuous RU.

[0976] The following describes the method provided in the embodiments of the present application.

[0977] FIG4 is a flow chart of a communication method provided in an embodiment of the present application. The description of the first communication device and the second communication device involved in FIG4 can be referred to above and will not be described in detail here. As shown in FIG4, the method includes:

[0978] 401. A first communication device generates an OFDM symbol.

[0979] 402. The first communication device sends OFDM symbols according to subcarrier planning corresponding to the first bandwidth.

[0980] Correspondingly, the second communication device receives the above-mentioned OFDM symbols according to the subcarrier planning corresponding to the first bandwidth.

[0981] 403. The second communication device parses the OFDM symbol.

[0982] The first bandwidth is 160 MHz, and the subcarrier planning corresponding to the first bandwidth includes 996-tone DRU 1 and 996-tone DRU 2, or includes 484-tone DRU 1 to 484-tone DRU 4, or includes 242-tone DRU 1 to 242-tone DRU 8, or includes 106-tone DRU 1 to 106-tone DRU 16.

[0983] Among them, 996-tone DRU indicates a DRU including 996 subcarriers, 484-tone DRU indicates a DRU including 484 subcarriers, 242-tone DRU indicates a DRU including 242 subcarriers, and 106-tone DRU indicates a DRU including 106 subcarriers.

[0984] A 996-tone DRU can be divided into two 484-tone DRUs, a 484-tone DRU can be divided into two 242-tone DRUs, and a 242-tone DRU can be divided into two 106-tone DRUs.

[0985] For example, for different DRU sizes under the same bandwidth, the indexes of the DRUs may have the following relationship:

[0986] 242-tone DRU 1 may include 106-tone DRU 1 + 106-tone DRU 2, 242-tone DRU 2 may include 106-tone DRU 3 + 106-tone DRU 4, 242-tone DRU 3 may include 106-tone DRU 5 + 106-tone DRU 6, and so on. 242-tone DRU 7 may include 106-tone DRU 13 + 106-tone DRU 14, and 242-tone DRU 8 may include 106-tone DRU 15 + 106-tone DRU 16.

[0987] 484-tone DRU 1 can include 242-tone DRU 1 + 242-tone DRU 2, 484-tone DRU 2 can include 242-tone DRU 3 + 242-tone DRU 4, 484-tone DRU 3 can include 242-tone DRU 5 + 242-tone DRU 6, and 484-tone DRU 4 can include 242-tone DRU 7 + 242-tone DRU 8;

[0988] 996-tone DRU 1 can include 484-tone DRU 1 + 484-tone DRU 2, and 996-tone DRU 2 can include 484-tone DRU 3 + 484-tone DRU 4.

[0989] The description of the subcarrier planning corresponding to the first bandwidth can be referred to below and will not be described in detail here. The numbers in this application are for distinguishing different DRUs and do not limit this application.

[0990] Generally speaking, the subcarrier index range (subcarrier index range) can be used to represent the position of the subcarrier in the subcarrier planning corresponding to the first bandwidth in the frequency domain. For the index range, the middle index can be 0, the right side of 0 can be +1, and the left side of 0 can be -1. As for the number of subcarriers included on the left side of 0 (which can also be understood as the index range), and the number of subcarriers included on the right side of 0 (which can also be understood as the index range), it can be determined by the total number of subcarriers. When the total number of subcarriers is an odd number greater than 1, the number of subcarriers included on the left side of 0 and the number of subcarriers included on the right side of 0 can be the same. When the total number of subcarriers is an even number greater than 2, the number of subcarriers included on the left side of 0 and the number of subcarriers included on the right side of 0 will be different. Generally speaking, the number of subcarriers included on the right side of 0 can be less than the number of subcarriers included on the left side of 0. However, the present application is not limited to this.

[0991] The index range involved in the subcarrier planning corresponding to the first bandwidth can be determined based on the first bandwidth and the subcarrier spacing. Taking the subcarrier spacing of 78.125KHz as an example, 160MHz can have 2048 (i.e., 160MHz / 78.125KHz=2048) subcarriers. Taking the example that the number of subcarriers included to the left of 0 is greater than the number of subcarriers included to the right of 0, the index range of these 2048 subcarriers can be [-1024:1023]. In other words, from low to high frequency, the index of these 2048 subcarriers can be [-1024:1023]. Of course, as the standard progresses, the subcarrier spacing may also change. When the subcarrier spacing changes, the number of subcarriers in this application and the subcarrier index of each DRU may also change accordingly. Regardless of how the subcarrier spacing changes, as long as the method for determining the index of each DRU is the same as below, it falls within the protection scope of the embodiment of this application.

[0992] In the embodiment of the present application, the subcarrier planning corresponding to 160MHz is designed in detail. Each DRU under the subcarrier planning can achieve a larger power amplification factor, thereby improving the transmission power of the communication device.

[0993] The following introduces the subcarrier planning involved in the embodiments of the present application.

[0994] The following provides four subcarrier plans for 160MHz. In specific implementations, the standard may define one of the subcarrier plans, or may define two of them, etc., and the embodiments of this application do not limit this. For any of the subcarrier plans, at 160MHz, the standard can directly define the indexes of two 996-tone DRUs, four 484-tone DRUs, eight 242-tone DRUs, and 106-tone DRUs. Alternatively, the standard can also give index expressions for different DRUs, etc., and this application does not limit the specific method of the standard.

[0995] First subcarrier planning:

[0996] In one possible implementation, the subcarrier planning corresponding to the first bandwidth may include a first protection area, a first data pilot area, a first DC area, a second data pilot area, a second DC area, a third data pilot area, a third DC area, a fourth data pilot area and a second protection area.

[0997] The subcarriers in the first protection area and the second protection area may be protection subcarriers, and the subcarriers in the first DC area and the third DC area may be DC subcarriers. Generally speaking, the subcarriers in the second DC area may be DC subcarriers, but this application is not limited to this. The first data pilot area, the second data pilot area, the third data pilot area, and the fourth data pilot area may include data subcarriers and pilot subcarriers. Optionally, the four data pilot areas may include null subcarriers. The names of the above-mentioned areas are only examples and should not be understood as limitations on the embodiments of the present application.

[0998] The first data pilot area can be located between the first protection area and the first DC area, the second data pilot area can be located between the first DC area and the second DC area, the third data pilot area can be located between the second DC area and the third DC area, and the fourth data pilot area can be located between the third DC area and the second protection area. Figure 5a is a schematic diagram of the area division provided in an embodiment of the present application. Figure 5a exemplarily shows the frequency domain positions of the above-mentioned areas.

[0999] The embodiment of the present application will design DRUs of different sizes in the first data pilot area, the second data pilot area, the third data pilot area, and the fourth data pilot area. For example, for the above four data pilot areas, the embodiment of the present application respectively designs two 996-tone DRUs (such as 996-tone DRU 1 and 996-tone DRU 2), four 484-tone DRUs (such as 484-tone DRU 1, 484-tone DRU 2, 484-tone DRU 3, and 484-tone DRU 4), ​​eight 242-tone DRUs (such as 242-tone DRU 1 to 242-tone DRU 8), and sixteen 106-tone DRUs (such as 106-tone DRU 1 to 106-tone DRU 16). DRUs of different sizes can be separate embodiments, or DRUs of different sizes can be combined into one embodiment, which is not limited by the present application. The following is a detailed description:

[1000] 1A, 996-tone DRU

[1001] 996-tone DRU 1 can meet the following conditions:

[1002] Condition 1: 996-tone DRU 1 is distributed in the first data pilot region, the second data pilot region, the third data pilot region, and the fourth data pilot region. 996-tone DRU 1 includes even-indexed subcarriers in the first data pilot region, the second data pilot region, the third data pilot region, and the fourth data pilot region.

[1003] 996-tone DRU 1 can meet the following conditions:

[1004] Condition 2: 996-tone DRU 2 is distributed in the first data pilot region, the second data pilot region, the third data pilot region, and the fourth data pilot region. 996-tone DRU 2 includes subcarriers with odd indexes in the first data pilot region, the second data pilot region, the third data pilot region, and the fourth data pilot region.

[1005] As an example, the first to fourth data pilot regions may not include null subcarriers. For example, the total number of subcarriers in these four data pilot regions is 996*2=1992. In other words, the total number of subcarriers in the first guard region, the second DC region, the second guard region, the first DC region, and the third DC region is 2048-1992=56.

[1006] As another example, the first to fourth data pilot regions may include null subcarriers. For example, the total number of subcarriers remaining in these four data pilot regions, excluding the null subcarriers, may be 1992. In other words, the total number of subcarriers in the first guard region, the second DC region, the second guard region, the first DC region, and the third DC region may be less than 56.

[1007] The description of each area here also applies to the following 1B to 1D and will not be repeated below.

[1008] In this application, for the convenience of subsequent reference, when it comes to the conditions that DRUs meet, different conditions that different DRUs meet are distinguished by different numbers, but this should not be understood as a limitation on the embodiments of this application.

[1009] 996-tone DRU 1 can meet the following conditions:

[1010] Condition 3: The difference between the index of the last subcarrier of 996-tone DRU 1 in the first data pilot region and the index of its first subcarrier in the second data pilot region is an integer multiple of 2, the difference between the index of the last subcarrier in the second data pilot region and the index of its first subcarrier in the third data pilot region is an integer multiple of 2, and the difference between the index of the last subcarrier in the third data pilot region and the index of the first subcarrier in the fourth data pilot region is an integer multiple of 2.

[1011] In other words, the difference between the index of the last subcarrier of 996-tone DRU 1 in the first data pilot area and the index of its first subcarrier in the second data pilot area is an integer multiple of the index difference of adjacent subcarriers in the same data pilot area, the difference between the index of the last subcarrier in the second data pilot area and the index of its first subcarrier in the third data pilot area is an integer multiple of the index difference of adjacent subcarriers in the same data pilot area, and the difference between the index of the last subcarrier in the third data pilot area and the index of the first subcarrier in the fourth data pilot area is an integer multiple of the index difference of adjacent subcarriers in the same data pilot area.

[1012] For example, the difference between the index of the last subcarrier in the first data pilot area (i.e., the end index in the first data pilot area) of 996-tone DRU 1 and the index of the first subcarrier in the second data pilot area (i.e., the start index in the second data pilot area) can be 2, 4, 6, 8, 10, 12, 14, 16, 18 or 20, etc., which are not listed here one by one.

[1013] The difference between the index of the last subcarrier of the above-mentioned 9996-tone DRU 1 in the first data pilot area and the index of its first subcarrier in the second data pilot area, the difference between the index of the last subcarrier in the second data pilot area and the index of its first subcarrier in the third data pilot area, and the difference between the index of the last subcarrier in the third data pilot area and the index of its first subcarrier in the fourth data pilot area is 2. Whether the above-mentioned differences are the same is not limited in this embodiment of the present application.

[1014] 996-tone DRU 2 can satisfy the following relationship:

[1015] Condition 4: The difference between the index of the last subcarrier of 996-tone DRU 2 in the first data pilot region and the index of its first subcarrier in the second data pilot region is an integer multiple of 2, the difference between the index of the last subcarrier in the second data pilot region and the index of its first subcarrier in the third data pilot region is an integer multiple of 2, and the difference between the index of the last subcarrier in the third data pilot region and the index of the first subcarrier in the fourth data pilot region is an integer multiple of 2.

[1016] For the description of condition 4, please refer to condition 3 and will not be elaborated here.

[1017] In the embodiment of the present application, by satisfying the above conditions in the data pilot area, the peak to average power ratio (PAPR) of the 996-tone DRU 1 or 996-tone DRU 2 can be ensured to be low.

[1018] When the conditions are met, the index of 996-tone DRU can be designed within the four data pilot areas in the subcarrier planning, which can not only improve the power gain but also ensure a low PAPR.

[1019] As a possible implementation manner 1, the index of the first data pilot area is [-1012:-515], the index of the second data pilot area is [-509:-12], the index of the third data pilot area is [12:509], and the index of the fourth data pilot area is [515:1012].

[1020] Since the index of the first subcarrier in the first data pilot region is an even number, the index of the first subcarrier in the second data pilot region is an odd number, the index of the first subcarrier in the third data pilot region is an even number, and the index of the first subcarrier in the fourth data pilot region is an odd number, the above 996-tone DRU 1 includes subcarriers with even indexes in the first data pilot region, the second data pilot region, the third data pilot region, and the fourth data pilot region, which can also be replaced by: 996-tone DRU 1 includes the odd-numbered subcarriers in the first data pilot region, the even-numbered subcarriers in the second data pilot region, the odd-numbered subcarriers in the third data pilot region, and the even-numbered subcarriers in the fourth data pilot region. Similarly, 996-tone DRU 2 includes the even-numbered subcarriers in the first data pilot region, the odd-numbered subcarriers in the second data pilot region, the even-numbered subcarriers in the third data pilot region, and the odd-numbered subcarriers in the fourth data pilot region.

[1021] The first guard region may be indexed as [-1024:-1013], and the second guard region may be indexed as [1013:1023]. That is, from low to high frequency, the 1st to 12th subcarriers of the 2048 subcarriers are guard subcarriers, and the 2038th to 2048th subcarriers are guard subcarriers.

[1022] The first DC sub-region may be indexed as [-514:-510], the second DC sub-region as [-11:11], and the third DC sub-region as [510:514]. That is, from low to high frequency, the 511th to 515th sub-carriers among the 2048 sub-carriers are DC sub-carriers, the 1014th to 1036th sub-carriers are DC sub-carriers (or guard sub-carriers), and the 1535th to 1539th sub-carriers are DC sub-carriers.

[1023] In an embodiment of the present application, the above-mentioned division method is used to divide each area, so that each of the four data pilot areas can include 498 subcarriers, and the number of subcarriers in the four data pilot areas of 996-tone DRU 1 or 996-tone DRU 2 can be 249, so that the 498 subcarriers in each data pilot area can be used to design a 996-tone DRU, thereby improving the utilization efficiency of subcarriers.

[1024] Of course, the index ranges of the various areas listed in the above implementation method 1 are only examples. For example, in a specific implementation, the index range of at least one of the first protection area, the second DC area, the second protection area, the first DC area, or the third DC area may be smaller, and the embodiment of the present application is not limited thereto. When the index range of at least one of the first protection area, the second protection area, the first DC area, the second DC area, or the third DC area is smaller, the index range of the first data pilot area to the fourth data pilot area may be larger. At this time, these four data pilot areas may include empty subcarriers.

[1025] In this application, in order to facilitate subsequent references, different implementations are distinguished by numbering, but this should not be understood as a limitation to the embodiments of this application.

[1026] In combination with the above-mentioned condition 1 or condition 3 satisfied by the 996-tone DRU 1 and the indexes of the various areas shown in implementation method 1, the embodiment of the present application further provides an index of the 996-tone DRU 1, as shown below:

[1027] The subcarrier indexes of 996-tone DRU 1 are [-1012:2:-516,-508:2:-12,12:2:508,516:2:1012]. That is, the subcarrier indexes of 996-tone DRU 1 are [-1012,-1010,-1008,…,-518,-516,-508,-506,…,-14,-12,12,14,16…,506,508,516,518,…,1010,1012].

[1028] In this application, [a:x:b] can represent integers from a to b with x as the increment, that is, a, (a+x), (a+2x), (a+3x), ..., b. For example, [-1012:2:-516] represents -1012, (-1012+2=-1010), (-1012+2*2=-1008), ..., -518, -516.

[1029] In combination with the above-mentioned condition 2 or condition 4 satisfied by the 996-tone DRU 2 and the indexes of the various areas shown in implementation method 1, the embodiment of the present application further provides an index of the 996-tone DRU 2, as shown below:

[1030] The subcarrier indexes of 996-tone DRU 2 are [-1011:2:-515,-509:2:-13,13:2:509,515:2:1011]. In other words, the subcarrier indexes of 996-tone DRU 2 are [-1011,-1009,-1007,...-517,-515,-509,-507,...,-15,-13,13,15,17,...,507,509,515,517,...,1009,1011].

[1031] As can be seen from the above indexes, for 996-tone DRU 1, the index of the last subcarrier in the first data pilot region is -516, and the index of the first subcarrier in the second data pilot region is -508, where -508-(-516)=8, meaning the index difference is 8. The index of the last subcarrier in the second data pilot region is -12, and the index of the first subcarrier in the third data pilot region is 12, resulting in an index difference of 24 (12-(-12)=8). The index of the last subcarrier in the third data pilot region is 508, and the index of the first subcarrier in the fourth data pilot region is 516, resulting in an index difference of 8 (516-508=8). At the same time, for 996-tone DRU 1, the difference between the indices of adjacent subcarriers in each data pilot region is 2. In other words, the indexes of the above 996-tone DRU meet the above conditions 1 and 3. Similarly, 996-tone DRU 2 meets the above conditions 2 and 4.

[1032] In this embodiment, 996-tone DRU 1 or 996-tone DRU 2 are evenly distributed across the four data pilot areas, facilitating channel smoothing. Furthermore, by satisfying Condition 3 or Condition 4, a low PAPR can be achieved. In this embodiment, the 996-tone DRU achieves a power gain of 2.69 dB. For more detailed calculation methods, please refer to the terminology regarding distributed resource units above.

[1033] 1B, 484-tone DRU

[1034] 484-tone DRU 1, 484-tone DRU 2, 484-tone DRU 3, and 484-tone DRU 4 are all distributed in the first, second, third, and fourth data pilot areas. That is, 484-tone DRU 1 is distributed in the four aforementioned data pilot areas, 484-tone DRU 2 is distributed in the four aforementioned data pilot areas, 484-tone DRU 3 is distributed in the four aforementioned data pilot areas, and 484-tone DRU 4 is distributed in the four aforementioned data pilot areas.

[1035] 484-tone DRU 1 to 484-tone DRU 4 meet at least one of the following conditions:

[1036] Condition 1: The index difference of adjacent subcarriers of any 484-tone DRU 1 to 484-tone DRU 4 distributed in the first data pilot area is 4, the index difference of adjacent subcarriers of any 484-tone DRU distributed in the second data pilot area is 4, the index difference of adjacent subcarriers of any 484-tone DRU distributed in the third data pilot area is 4, and the index difference of adjacent subcarriers of any 484-tone DRU distributed in the fourth data pilot area is 4.

[1037] In other words, for any 484-tone DRU among 484-tone DRU 1 to 484-tone DRU 4, the index difference between adjacent subcarriers distributed in each data pilot region is 4.

[1038] For example, if the subcarrier indices are 1, 5, 9, and 13, then 1 and 5 can be called adjacent subcarriers, or 5 and 9 can also be called adjacent subcarriers, or 9 and 13 can also be called adjacent subcarriers. The subcarrier indices shown here are only examples and do not represent the subcarriers in the 484-tone DRU shown in the embodiments of the present application.

[1039] In the embodiment of the present application, the 484-tone DRU can achieve a larger power amplification factor, such as 5.12dB, by satisfying condition 1.

[1040] Condition 2: The p-th subcarrier in 484-tone DRU 1, the p-th subcarrier in 484-tone DRU 2, the p-th subcarrier in 484-tone DRU 3, and the p-th subcarrier in 484-tone DRU 4 are continuous.

[1041] For example, the p-th subcarrier in 484-tone DRU 1, the p-th subcarrier in 484-tone DRU 3, the p-th subcarrier in 484-tone DRU 2, and the p-th subcarrier in 484-tone DRU 4 are sequentially arranged. Of course, the order shown here is only an example. As the number of the 484-tone DRUs changes, the order shown here will also change, and this application does not limit this.

[1042] Among them, p can be a positive integer less than or equal to 484. That is, the value of p can be the same as the number of subcarriers in the DRU. When the subcarrier with the lowest frequency is called the 0th subcarrier in order from low to high frequency, the value of p can be an integer greater than or equal to 0 and less than 484. This application does not limit the specific value range of p. The description of p here also applies to the following text and will not be repeated below.

[1043] In this embodiment of the present application, by satisfying the aforementioned condition 2, the four 484-tone DRUs can ensure that they form an integral translation relationship, which facilitates index storage and retrieval. Furthermore, for the same LTF sequence, the four 484-tone DRUs have the same PAPR. Therefore, the four 484-tone DRUs can share the same sequence, simplifying sequence design.

[1044] For example, the 484-tone DRU may also satisfy the following condition 3:

[1045] Any 484-tone DRU includes 120 subcarriers or 122 subcarriers in the first data pilot region;

[1046] Any 484-tone DRU includes 120 subcarriers or 122 subcarriers in the second data pilot region;

[1047] Any 484-tone DRU includes 120 subcarriers or 122 subcarriers in the third data pilot region;

[1048] Any 484-tone DRU includes 120 subcarriers or 122 subcarriers in the fourth data pilot region.

[1049] Since 120*2+122*2=484, any 484-tone DRU may include 120 subcarriers (or 122 subcarriers) in any two of the four data pilot areas, and 122 subcarriers (or 120 subcarriers) in the remaining two data pilot areas. For example, for different 484-tone DRUs, the number of subcarriers in the same data pilot area may be the same.

[1050] As an example 1, any 484-tone DRU may include 120 subcarriers in the first data pilot region and the second data pilot region, and 122 subcarriers in the third data pilot region and the fourth data pilot region. The example numbers shown in this application are for convenience of reference below and should not be construed as limiting the embodiments of this application.

[1051] As another example 2, any 484-tone DRU may include 120 subcarriers in the first data pilot region and the third data pilot region, and may include 122 subcarriers in the second data pilot region and the fourth data pilot region.

[1052] As yet another example 3, any 484-tone DRU may include 120 subcarriers in the first data pilot region and the fourth data pilot region, and may include 122 subcarriers in the second data pilot region and the third data pilot region.

[1053] As yet another example 4, any 484-tone DRU may include 122 subcarriers in the first data pilot region and the second data pilot region, and include 120 subcarriers in the third data pilot region and the fourth data pilot region.

[1054] As yet another example 5, any 484-tone DRU may include 122 subcarriers in the first data pilot region and the third data pilot region, and may include 120 subcarriers in the second data pilot region and the fourth data pilot region.

[1055] As yet another example 6, any 484-tone DRU may include 122 subcarriers in the first data pilot region and the fourth data pilot region, and may include 120 subcarriers in the second data pilot region and the third data pilot region.

[1056] In the embodiment of the present application, by satisfying the above condition 3, when designing a 242-tone DRU based on the 484-tone DRU, the p-th subcarrier of each 242-tone DRU corresponding to the 484-tone DRU can be continuous, p∈[1,242], so that each 242-tone DRU forms an overall translation relationship, which is beneficial to the storage and reading of the index.

[1057] For example, the 484-tone DRU may also satisfy the following condition 4:

[1058] For any 484-tone DRU, the difference between the index of the last subcarrier in the first data pilot region and the index of the first subcarrier in the second data pilot region is an integer multiple of 4, the difference between the index of the last subcarrier in the second data pilot region and the index of the first subcarrier in the third data pilot region is an integer multiple of 4, and the difference between the index of the last subcarrier in the third data pilot region and the index of the first subcarrier in the fourth data pilot region is an integer multiple of 4.

[1059] In other words, for any 484-tone DRU, the difference between the index of the last subcarrier in the first data pilot region and the index of the first subcarrier in the second data pilot region is an integer multiple of the index difference between the adjacent subcarriers in the same data pilot region (i.e., 4), the difference between the index of the last subcarrier in the second data pilot region and the index of the first subcarrier in the third data pilot region is an integer multiple of the index difference between the adjacent subcarriers in the same data pilot region, and the difference between the index of the last subcarrier in the third data pilot region and the index of the first subcarrier in the fourth data pilot region is an integer multiple of the index difference between the adjacent subcarriers in the same data pilot region.

[1060] For example, for any 484-tone DRU, the difference between the index of the last subcarrier in the first data pilot area and the index of the first subcarrier in the second data pilot area can be 4, 8, 12, 16, 20, 24, 28 or 32, etc., which are not listed here one by one.

[1061] For any 484-tone DRU, the difference between the index of the last subcarrier in the first data pilot area and the index of the first subcarrier in the second data pilot area, the difference between the index of the last subcarrier in the second data pilot area and the index of the first subcarrier in the third data pilot area, and the difference between the index of the last subcarrier in the third data pilot area and the index of the first subcarrier in the fourth data pilot area, as to whether the above differences are the same, is not limited in this embodiment of the present application.

[1062] In the embodiment of the present application, the 484-tone DRU can ensure a low PAPR by satisfying the above condition 4.

[1063] For example, the 484-tone DRU may also satisfy the following condition 5:

[1064] For any 484-tone DRU, its 120 subcarriers or 122 subcarriers in the first data pilot region can be shifted within the first data pilot region, or its 120 subcarriers or 122 subcarriers in the second data pilot region can be shifted within the second data pilot region, or its 120 subcarriers or 122 subcarriers in the third data pilot region can be shifted within the third data pilot region, or its 120 subcarriers or 122 subcarriers in the fourth data pilot region can be shifted within the fourth data pilot region.

[1065] For the description of translation, please refer to the various index expressions shown below. For example, the 484-tone DRU can meet the above condition 5 when the above conditions 1 to 4 are met. In a specific implementation, the 484-tone DRU can determine an index from the multiple different indexes of the four 484-tone DRUs when the above condition 5 is met. For example, the standard can define an index as the index of the 484-tone DRU, or the index expression shown below can be defined, which is not limited in the embodiments of the present application.

[1066] In the embodiment of the present application, when the above conditions 1 to 4 are met, the index of the 484-tone DRU can be designed in the four data pilot areas.

[1067] As a possible implementation, the index of the first data pilot area is [-1012:-515], the index of the second data pilot area is [-509:-12], the index of the third data pilot area is [12:509], and the index of the fourth data pilot area is [515:1012].

[1068] For the index description of the first protection area, the second DC area, the second protection area, the first DC area and the third DC area, please refer to the above implementation method 1 and will not be repeated here.

[1069] In the above four data pilot areas, four 484-tone DRUs can be designed if the above conditions 1 to 4 or conditions 1 to 5 are met. As an example, in the above four data pilot areas, four 484-tone DRUs can be designed independently. As another example, in the above four data pilot areas, four 484-tone DRUs can be designed in combination with the index of the 996-tone DRU shown above. The following will illustrate the index of the 484-tone DRU in combination with the two 996-tone DRUs shown above. For the relationship between the 484-tone DRU and the 996-tone DRU, please refer to the description of Figure 4 and will not be described in detail here.

[1070] The following describes various possibilities for indexing each 484-tone DRU.

[1071] For the first data pilot area:

[1072] In the case where any 484-tone DRU includes 120 subcarriers in the first data pilot region, the index can be expressed as:

[1073] The indices of the 120 subcarriers in the first data pilot region of the 484-tone DRU 1 are

[1074] The indices of the 120 subcarriers in the first data pilot region of the 484-tone DRU 2 are

[1075] The indices of the 120 subcarriers in the first data pilot region of the 484-tone DRU 3 are

[1076] The indices of the 120 subcarriers in the first data pilot region of the 484-tone DRU 4 are

[1077] in, or 18.

[1078] In the embodiment of this application, It can be called a shift value (or offset value or offset amount, etc.), which can be an integer. For example, when the starting index in the expression shown in the present application is the starting index of a data pilot area, the minimum value can be 0, and the maximum value can be determined based on the index of the last subcarrier of the aforementioned data pilot area. When a 484-tone DRU is designed based on a 996-tone DRU, the 484-tone DRU can be shifted within the index range of the 996-tone DRU. For example, when 484-tone DRU 1 and 484-tone DRU 2 are designed in combination with 996-tone DRU 1, the range in which the 484-tone DRU 1 can be shifted, and the range in which the 484-tone DRU 2 can be shifted are both less than or equal to the index range of 996-tone DRU 1. For example, the maximum value of the shift value of the above-mentioned 484-tone DRU 1 (or 484-tone DRU 2) can be determined based on the end index of 996-tone DRU 1. Furthermore, the shift value of the 484-tone DRU 1 in the first data pilot region can be determined based on the above conditions 1 to 4 and the index of the last subcarrier of the 996-tone DRU 1 in the first data pilot region. All can be integers. For example, the minimum value can be 0, and the maximum value can also be determined based on the index of the last subcarrier of the 996-tone DRU in the corresponding data pilot area. The methods for determining the maximum value (or minimum value) of each shift value in the second subcarrier planning, the third subcarrier planning, and the fourth subcarrier planning below are similar and will not be repeated here. The various expressions shown in the embodiments of the present application are only examples and should not be understood as limitations on the embodiments of the present application. For example, in some other expressions, the shift value can also be a negative number, which will not be listed here.

[1079] For example, in the case of designing indexes by combining DRUs of different sizes, such as designing a 242-tone DRU by combining a 484-tone DRU, designing a 242-tone DRU by combining a 996-tone DRU, designing a 106-tone DRU by combining a 242-tone DRU, and designing a 106-tone DRU by combining a 484-tone DRU. In the case of DRU (not listed here one by one), the various shift values ​​in this application need to meet at least one of the following conditions: (1) For any size of DRU, the difference between the index of the last subcarrier in the first data pilot area and the index of the first subcarrier in the second data pilot area is an integer multiple of the index difference of its adjacent subcarriers, the difference between the index of the last subcarrier in the second data pilot area and the index of the first subcarrier in the third data pilot area is an integer multiple of the index difference of its adjacent subcarriers, and the difference between the index of the last subcarrier in the third data pilot area and the index of the first subcarrier in the fourth data pilot area is an integer multiple of the index difference of its adjacent subcarriers; (2) The shift value of 484-tone DRU is equal to the shift value of 242-tone DRU; (3) The shift value of 106-tone DRU is equal to the shift value of 484-tone DRU 8k, where k is a positive integer. In addition to the above conditions, each shift value also needs to meet the conditions met by the corresponding DRU.

[1080] In this application, This value may correspond to the first data pilot region and 120 subcarriers. That is, the "1" or "2" in the subscript may distinguish 120 or 122, and the "1" to "4" in the superscript may indicate the region number. This description applies to all embodiments of the present application.

[1081] In the case where any 484-tone DRU includes 122 subcarriers in the first data pilot region, the index can be expressed as:

[1082] The indices of the 122 subcarriers in the first data pilot region of the 484-tone DRU 1 are

[1083] The indices of the 122 subcarriers in the first data pilot region of the 484-tone DRU 2 are

[1084] The indices of the 122 subcarriers in the first data pilot region of the 484-tone DRU 3 are

[1085] The indices of the 122 subcarriers in the first data pilot region of the 484-tone DRU 4 are

[1086] in, or 10.

[1087] For the second data pilot area:

[1088] In the case where any 484-tone DRU includes 120 subcarriers in the second data pilot region, the index can be expressed as:

[1089] The indices of the 120 subcarriers in the second data pilot region of the 484-tone DRU 1 are

[1090] The indices of the 120 subcarriers in the second data pilot region of the 484-tone DRU 2 are

[1091] The indices of the 120 subcarriers in the second data pilot region of the 484-tone DRU 3 are

[1092] The indices of the 120 subcarriers in the second data pilot region of the 484-tone DRU 4 are

[1093] in, or 16.

[1094] In the case where any 484-tone DRU includes 122 subcarriers in the second data pilot region, the index can be expressed as:

[1095] The indices of the 122 subcarriers in the second data pilot region of the 484-tone DRU 1 are

[1127] The following exemplifies the index of each 484-tone DRU.

[1128] The following This section uses an example to describe the index of a 484-tone DRU.

[1134] Taking Example 2 above as an example, the number of subcarriers in the four data pilot areas of any 484-tone DRU is 120, 122, 120, and 122 respectively:

[1135] The index of 484-tone DRU 1 is [-1012:4:-536,-508:4:-24,12:4:488,516:4:1000],

[1138] The index of 484-tone DRU 4 is [-1009:4:-533,-505:4:-21,15:4:491,519:4:1003].

[1139] Taking Example 3 above as an example, the number of subcarriers in the four data pilot areas of any 484-tone DRU is 120, 122, 122, and 120, respectively:

[1140] The index of 484-tone DRU 1 is [-1012:4:-536,-508:4:-24,12:4:496,516:4:992],

[1144] The indexes corresponding to Examples 4 to 6 above, or other values ​​of the translation value, are not listed here one by one.

[1145] In the embodiment of the present application, other indexes of the 484-tone DRU can also be obtained based on the above content, but they are not listed here one by one due to limited space.

[1146] 1C, 242-tone DRU

[1147] 242-tone DRU 1, 242-tone DRU 2, 242-tone DRU 3, 242-tone DRU 4, 242-tone DRU 5, 242-tone DRU 6, 242-tone DRU 7, and 242-tone DRU 8 are all distributed in the first data pilot region, the second data pilot region, the third data pilot region, and the fourth data pilot region. In other words, 242-tone DRU 1 is distributed in the first data pilot area, the second data pilot area, the third data pilot area, and the fourth data pilot area; 242-tone DRU 2 is distributed in the first data pilot area, the second data pilot area, the third data pilot area, and the fourth data pilot area; 242-tone DRU 3 is distributed in the first data pilot area, the second data pilot area, the third data pilot area, and the fourth data pilot area; 242-tone DRU 4 is distributed in the first data pilot area, the second data pilot area, the third data pilot area, and the fourth data pilot area; 242-tone DRU 5 is distributed in the first data pilot area, the second data pilot area, the third data pilot area, and the fourth data pilot area; 242-tone DRU 6 is distributed in the first data pilot area, the second data pilot area, the third data pilot area, and the fourth data pilot area; 242-tone DRU 7 are distributed in the first data pilot area, the second data pilot area, the third data pilot area and the fourth data pilot area, and the 242-tone DRU 8 are distributed in the first data pilot area, the second data pilot area, the third data pilot area and the fourth data pilot area.

[1148] 242-tone DRU 1 to 242-tone DRU 8 meet at least one of the following conditions:

[1149] Condition 1: The index difference of adjacent subcarriers of any 242-tone DRU 1 to 242-tone DRU 8 distributed in the first data pilot area is 8, the index difference of adjacent subcarriers of any 242-tone DRU distributed in the second data pilot area is 8, the index difference of adjacent subcarriers of any 242-tone DRU distributed in the third data pilot area is 8, and the index difference of adjacent subcarriers of any 242-tone DRU distributed in the fourth data pilot area is 8.

[1150] In other words, for any 242-tone DRU among 242-tone DRU 1 to 242-tone DRU 8, the index difference of adjacent subcarriers distributed in each data pilot region is 8. For the description of adjacent subcarriers, please refer to 1B above and will not be described in detail here.

[1151] In the embodiment of the present application, the 242-tone DRU can achieve a larger power amplification factor, such as 8.13dB, by satisfying the above condition 1.

[1152] Condition 2: The p-th subcarrier in 242-tone DRU 1, the p-th subcarrier in 242-tone DRU 2, the p-th subcarrier in 242-tone DRU 3, the p-th subcarrier in 242-tone DRU 4, the p-th subcarrier in 242-tone DRU 5, the p-th subcarrier in 242-tone DRU 6, the p-th subcarrier in 242-tone DRU 7, and the p-th subcarrier in 242-tone DRU 8 are continuous.

[1153] For example, the p-th subcarrier in 242-tone DRU 1, the p-th subcarrier in 242-tone DRU 5, the p-th subcarrier in 242-tone DRU 3, the p-th subcarrier in 242-tone DRU 7, the p-th subcarrier in 242-tone DRU 2, the p-th subcarrier in 242-tone DRU 6, the p-th subcarrier in 242-tone DRU 4, and the p-th subcarrier in 242-tone DRU 8 are sequentially arranged. Of course, the order shown here is only an example. As the numbering of the 242-tone DRUs changes, the order shown here will also change, and this application does not limit this.

[1154] Here, p can be a positive integer less than or equal to 242.

[1155] In the embodiment of the present application, the 242-tone DRU can ensure that the eight 242-tone DRUs form an overall translation relationship by satisfying the above condition 2, which is beneficial to the simplification of index storage and sequence design.

[1156] For example, the 242-tone DRU may also satisfy the following condition 3:

[1157] Any 242-tone DRU includes 60 subcarriers or 61 subcarriers in the first data pilot region;

[1158] Any 242-tone DRU includes 60 subcarriers or 61 subcarriers in the second data pilot region;

[1159] Any 242-tone DRU includes 60 subcarriers or 61 subcarriers in the third data pilot region;

[1160] Any 242-tone DRU includes 60 subcarriers or 61 subcarriers in the fourth data pilot region.

[1161] Since 60*2+61*2=242, any 242-tone DRU may include 60 subcarriers (or 61 subcarriers) in any two of the four data pilot areas, and 61 subcarriers (or 60 subcarriers) in the remaining two data pilot areas. For example, for different 242-tone DRUs, the number of subcarriers in the same data pilot area may be the same.

[1162] As an example 1, any 242-tone DRU may include 60 subcarriers in the first data pilot region and the second data pilot region, and include 61 subcarriers in the third data pilot region and the fourth data pilot region.

[1163] As another example 2, any 242-tone DRU may include 60 subcarriers in the first data pilot region and the third data pilot region, and may include 61 subcarriers in the second data pilot region and the fourth data pilot region.

[1164] As yet another example 3, any 242-tone DRU may include 60 subcarriers in the first data pilot region and the fourth data pilot region, and may include 61 subcarriers in the second data pilot region and the third data pilot region.

[1165] As yet another example 4, any 242-tone DRU may include 61 subcarriers in the first data pilot region and the second data pilot region, and include 60 subcarriers in the third data pilot region and the fourth data pilot region.

[1166] As yet another example 5, any 242-tone DRU may include 61 subcarriers in the first data pilot region and the third data pilot region, and may include 60 subcarriers in the second data pilot region and the fourth data pilot region.

[1167] As yet another example 6, any 242-tone DRU may include 61 subcarriers in the first data pilot region and the fourth data pilot region, and may include 60 subcarriers in the second data pilot region and the third data pilot region.

[1168] For example, the 242-tone DRU may also satisfy the following condition 4:

[1169] For any 242-tone DRU, the difference between the index of the last subcarrier in the first data pilot region and the index of the first subcarrier in the second data pilot region is an integer multiple of 8, the difference between the index of the last subcarrier in the second data pilot region and the index of the first subcarrier in the third data pilot region is an integer multiple of 8, and the difference between the index of the last subcarrier in the third data pilot region and the index of the first subcarrier in the fourth data pilot region is an integer multiple of 8.

[1170] In other words, for any 242-tone DRU, the difference between the index of the last subcarrier in the first data pilot region and the index of the first subcarrier in the second data pilot region is an integer multiple of the index difference between the adjacent subcarriers in the same data pilot region (i.e., 8), the difference between the index of the last subcarrier in the second data pilot region and the index of the first subcarrier in the third data pilot region is an integer multiple of the index difference between the adjacent subcarriers in the same data pilot region, and the difference between the index of the last subcarrier in the third data pilot region and the index of the first subcarrier in the fourth data pilot region is an integer multiple of the index difference between the adjacent subcarriers in the same data pilot region.

[1171] For example, for any 242-tone DRU, the difference between the index of the last subcarrier in the first data pilot region and the index of the first subcarrier in the second data pilot region can be 8, 16, 24, 32 or 40, etc., which are not listed here one by one.

[1172] For any 242-tone DRU, the difference between the index of the last subcarrier in the first data pilot area and the index of the first subcarrier in the second data pilot area, the difference between the index of the last subcarrier in the second data pilot area and the index of the first subcarrier in the third data pilot area, and the difference between the index of the last subcarrier in the third data pilot area and the index of the first subcarrier in the fourth data pilot area, whether the above differences are the same, is not limited in this embodiment of the present application.

[1173] In the embodiment of the present application, the 242-tone DRU can ensure a low PAPR by satisfying the above condition 4.

[1174] For example, the 242-tone DRU may also satisfy the following condition 5:

[1175] For any 242-tone DRU, its 60 subcarriers or 61 subcarriers in the first data pilot region can be shifted within the first data pilot region, or its 60 subcarriers or 61 subcarriers in the second data pilot region can be shifted within the second data pilot region, or its 60 subcarriers or 61 subcarriers in the third data pilot region can be shifted within the third data pilot region, or its 60 subcarriers or 61 subcarriers in the fourth data pilot region can be shifted within the fourth data pilot region.

[1176] For the description of translation, please refer to the various index expressions shown below. For example, the 242-tone DRU can meet the above condition 5 when the above conditions 1 to 4 are met. In a specific implementation, the 242-tone DRU can determine an index from the multiple different indexes of the four 242-tone DRUs when the above condition 5 is met. For example, the standard can define an index as the index of the 242-tone DRU, or the index expression shown below can be defined, and this application does not limit this.

[1177] In the embodiment of the present application, when the above conditions 1 to 4 are met, the index of the 242-tone DRU can be designed in the four data pilot areas.

[1178] As a possible implementation, the index of the first data pilot area is [-1012:-515], the index of the second data pilot area is [-509:-12], the index of the third data pilot area is [12:509], and the index of the fourth data pilot area is [515:1012].

[1179] For the index description of the first protection area, the second DC area, the second protection area, the first DC area and the third DC area, please refer to the above implementation method 1 and will not be repeated here.

[1180] Eight 242-tone DRUs can be designed within the four data pilot areas. As an example, eight 242-tone DRUs can be independently designed within the four data pilot areas. As another example, eight 242-tone DRUs can be designed within the four data pilot areas in combination with the 996-tone DRU described above. As yet another example, eight 242-tone DRUs can be designed within the four data pilot areas in combination with the 484-tone DRU described above. The relationship between the 242-tone DRU, 484-tone DRU, and 996-tone DRU can be described in Figure 4 and will not be further described here. When designing a 242-tone DRU in combination with the 484-tone DRU or 996-tone DRU shown above, the index range of the 242-tone DRU cannot exceed the index range of the 484-tone DRU or the index range of the 996-tone DRU. The same description of the combined design applies below.

[1286] Take Example 3 above as an example, that is, the number of subcarriers in the four data pilot areas of any 242-tone DRU is 60, 61, 61, and 60 respectively:

[1295] The indexes corresponding to Examples 4 to 6 above, or other values ​​of the translation value, are not listed here one by one.

[1296] In the embodiment of the present application, other indexes of the 242-tone DRU can also be obtained based on the above content, which will not be listed here one by one due to limited space.

[1297] When the 242-tone DRU is obtained based on the 484-tone DRU, as shown in FIG1B above, the odd-numbered subcarriers of each 484-tone DRU may constitute a 242-tone DRU, and the even-numbered subcarriers thereof may constitute another 242-tone DRU.

In this method, the index of each 242-tone DRU can be determined based on the index of the 484-tone DRU, which is not listed here.

[1298] 1D, 106-tone DRU

[1299] 106-tone DRU 1, 106-tone DRU 2, 106-tone DRU 3, 106-tone DRU 4, 106-tone DRU 5, 106-tone DRU 6, 106-tone DRU 7, 106-tone DRU 8, 106-tone DRU 9, 106-tone DRU 10, 106-tone DRU 11, 106-tone DRU 12, 106-tone DRU 13, 106-tone DRU 14, 106-tone DRU 15, and 106-tone DRU 16 are all distributed in the first data pilot region, the second data pilot region, the third data pilot region, and the fourth data pilot region.

[1301] 106-tone DRU 1 to 106-tone DRU 16 meet at least one of the following conditions:

[1302] Condition 1: The index difference of adjacent subcarriers of any 106-tone DRU 1 to 106-tone DRU 16 distributed in the first data pilot area is 16, the index difference of adjacent subcarriers of any 106-tone DRU distributed in the second data pilot area is 16, the index difference of adjacent subcarriers of any 106-tone DRU distributed in the third data pilot area is 8, and the index difference of adjacent subcarriers of any 106-tone DRU distributed in the fourth data pilot area is 16.

[1303] In other words, for any 106-tone DRU among 106-tone DRU 1 to 106-tone DRU 16, the index difference of adjacent subcarriers distributed in each data pilot region is 16. For the description of adjacent subcarriers, please refer to 1B above and will not be described in detail here.

[1304] In the embodiment of the present application, the 106-tone DRU can achieve a larger power amplification factor, such as 11.14 dB, by satisfying the above condition 1.

[1305] Condition 2: The p-th subcarrier in 106-tone DRU 1, the p-th subcarrier in 106-tone DRU 2, the p-th subcarrier in 106-tone DRU 3, the p-th subcarrier in 106-tone DRU 4, the p-th subcarrier in 106-tone DRU 5, the p-th subcarrier in 106-tone DRU 6, the p-th subcarrier in 106-tone DRU 7, the p-th subcarrier in 106-tone DRU 8, the p-th subcarrier in 106-tone DRU 9, the p-th subcarrier in 106-tone DRU 10, the p-th subcarrier in 106-tone DRU 11, the p-th subcarrier in 106-tone DRU 12, the p-th subcarrier in 106-tone DRU 13, the p-th subcarrier in 106-tone DRU 14, the p-th subcarrier in 106-tone DRU The p-th subcarrier in 15 and the p-th subcarrier in 106-tone DRU 16 are continuous. Of course, the order shown here is only an example, and as the number of the 106-tone DRU changes, the order shown here will also change, and this application does not limit this.

[1306] Here, p can be a positive integer less than or equal to 106.

[1307] In the embodiment of the present application, the 106-tone DRU can ensure that the 16 242-tone DRUs form an overall translation relationship by satisfying the above condition 2, which is beneficial to the storage of the index and the simplification of the sequence design.

[1308] For example, the 106-tone DRU may also satisfy the following condition 3:

[1309] Any 106-tone DRU includes 26 subcarriers or 27 subcarriers in the first data pilot region;

[1310] Any 106-tone DRU includes 26 subcarriers or 27 subcarriers in the second data pilot region;

[1311] Any 106-tone DRU includes 26 subcarriers or 27 subcarriers in the third data pilot region;

[1312] Any 106-tone DRU includes 26 subcarriers or 27 subcarriers in the fourth data pilot region.

[1313] For any 106-tone DRU, any two of the four data pilot regions may include 26 subcarriers (or 27 subcarriers), and the remaining two data pilot regions may include 27 subcarriers (or 26 subcarriers). For example, for different 106-tone DRUs, the number of subcarriers in the same data pilot region belonging to different 106-tone DRUs may be the same.

[1314] As an example 1, any 106-tone DRU may include 26 subcarriers in the first data pilot region and the second data pilot region, and include 27 subcarriers in the third data pilot region and the fourth data pilot region.

[1315] As another example 2, any 106-tone DRU may include 26 subcarriers in the first data pilot region and the third data pilot region, and may include 27 subcarriers in the second data pilot region and the fourth data pilot region.

[1316] As yet another example 3, any 106-tone DRU may include 26 subcarriers in the first data pilot region and the fourth data pilot region, and may include 27 subcarriers in the second data pilot region and the third data pilot region.

[1317] As yet another example 4, any 106-tone DRU may include 27 subcarriers in the first data pilot region and the second data pilot region, and include 26 subcarriers in the third data pilot region and the fourth data pilot region.

[1318] As yet another example 5, any 106-tone DRU may include 27 subcarriers in the first data pilot region and the third data pilot region, and may include 26 subcarriers in the second data pilot region and the fourth data pilot region.

[1319] As yet another example 6, any 106-tone DRU may include 27 subcarriers in the first data pilot region and the fourth data pilot region, and may include 26 subcarriers in the second data pilot region and the third data pilot region.

[1320] For example, the 106-tone DRU may also satisfy the following condition 4:

[1321] For any 106-tone DRU, the difference between the index of the last subcarrier in the first data pilot region and the index of the first subcarrier in the second data pilot region is an integer multiple of 16, the difference between the index of the last subcarrier in the second data pilot region and the index of the first subcarrier in the third data pilot region is an integer multiple of 16, and the difference between the index of the last subcarrier in the third data pilot region and the index of the first subcarrier in the fourth data pilot region is an integer multiple of 16.

[1322] In other words, for any 106-tone DRU, the difference between the index of the last subcarrier in the first data pilot region and the index of the first subcarrier in the second data pilot region is an integer multiple of the index difference between the adjacent subcarriers in the same data pilot region (i.e., 16), the difference between the index of the last subcarrier in the second data pilot region and the index of the first subcarrier in the third data pilot region is an integer multiple of the index difference between the adjacent subcarriers in the same data pilot region, and the difference between the index of the last subcarrier in the third data pilot region and the index of the first subcarrier in the fourth data pilot region is an integer multiple of the index difference between the adjacent subcarriers in the same data pilot region.

[1323] For example, for any 106-tone DRU, the difference between the index of the last subcarrier in the first data pilot region and the index of the first subcarrier in the second data pilot region may be 16 or 32, etc., which are not listed here one by one.

[1324] For any 106-tone DRU, the difference between the index of the last subcarrier in the first data pilot area and the index of the first subcarrier in the second data pilot area, the difference between the index of the last subcarrier in the second data pilot area and the index of the first subcarrier in the third data pilot area, and the difference between the index of the last subcarrier in the third data pilot area and the index of the first subcarrier in the fourth data pilot area, whether the above differences are the same, is not limited in this embodiment of the present application.

[1325] In the embodiment of the present application, the 106-tone DRU can ensure a low PAPR by satisfying the above condition 4.

[1326] For example, the 106-tone DRU may also satisfy the following condition 5:

[1327] For any 106-tone DRU, its 26 subcarriers or 27 subcarriers in the first data pilot region can be shifted within the first data pilot region, or its 26 subcarriers or 27 subcarriers in the second data pilot region can be shifted within the second data pilot region, or its 26 subcarriers or 27 subcarriers in the third data pilot region can be shifted within the third data pilot region, or its 26 subcarriers or 27 subcarriers in the fourth data pilot region can be shifted within the fourth data pilot region.

[1328] For explanations on translation, please refer to the various index expressions shown below. For example, a 106-tone DRU can satisfy the above condition 5 when the above conditions 1 to 4 are satisfied. In a specific implementation, the 106-tone DRU can determine an index from a variety of different indexes of four 106-tone DRUs when the above condition 5 is satisfied. For example, the standard can define an index as the index of the 106-tone DRU, or the index expression shown below can be defined, but this application does not limit this.

[1329] In the embodiment of the present application, when the above conditions 1 to 4 are met, the index of the 106-tone DRU can be designed in the four data pilot areas.

[1330] As a possible implementation, the index of the first data pilot area is [-1012:-515], the index of the second data pilot area is [-509:-12], the index of the third data pilot area is [12:509], and the index of the fourth data pilot area is [515:1012].

[1331] For the index description of the first protection area, the second DC area, the second protection area, the first DC area and the third DC area, please refer to the above implementation method 1 and will not be repeated here.

[1332] Sixteen 106-tone DRUs can be designed within the four data pilot areas. As an example, sixteen 106-tone DRUs can be independently designed within the four data pilot areas. As another example, sixteen 106-tone DRUs can be designed within the four data pilot areas in combination with the 996-tone DRU described above. As yet another example, eight 106-tone DRUs can be designed within the four data pilot areas in combination with the 484-tone DRU described above. As yet another example, sixteen 106-tone DRUs can be designed within the four data pilot areas in combination with the 242-tone DRU described above. The relationship between the 106-tone DRU, 242-tone DRU, 484-tone DRU, and 996-tone DRU can be found in the description of Figure 4 and will not be detailed here. When designing a 106-tone DRU by combining the 242-tone DRU, 484-tone DRU, or 996-tone DRU shown above, the index range of the 106-tone DRU cannot exceed the index range of the 242-tone DRU, the index range of the 484-tone DRU, or the index range of the 996-tone DRU. The instructions for combining designs here also apply below.

[1333] The following describes various possible indexes for each 106-tone DRU. For an explanation of the shift value, please refer to 1B above and will not be repeated here.

[1561] 996-tone DRU 2 can satisfy the following relationship:

[1563] For the description of 996-tone DRU 1 and 996-tone DRU 2, please refer to 1A above and will not be described in detail here.

[1564] In the embodiment of the present application, by satisfying the above conditions in the data pilot area, the peak to average power ratio (PAPR) of the 996-tone DRU 1 or 996-tone DRU 2 can be ensured to be low.

[1565] When the conditions are met, the index of 996-tone DRU can be designed within the four data pilot areas, which can not only improve the power amplification factor but also ensure a low PAPR.

[1566] In a possible implementation, the index of the first data pilot area is [-1012:-515], the index of the second data pilot area is [-509:-12], the index of the third data pilot area is [12:509], and the index of the fourth data pilot area is [515:1012].

[1567] Since the index of the first subcarrier in the first data pilot region is an even number, the index of the first subcarrier in the second data pilot region is an odd number, the index of the first subcarrier in the third data pilot region is an even number, and the index of the first subcarrier in the fourth data pilot region is an odd number, the above 996-tone DRU 1 includes the first data pilot region, the second data pilot region, the third data pilot region, and the odd-numbered subcarriers in the fourth data pilot region, and can also be replaced by: 996-tone DRU 1 includes subcarriers indexed as even numbers in the first data pilot region, subcarriers indexed as odd numbers in the second data pilot region, subcarriers indexed as even numbers in the third data pilot region, and subcarriers indexed as odd numbers in the fourth data pilot region. Similarly, 996-tone DRU 2 includes the first data pilot area, the second data pilot area, the third data pilot area, and the even-numbered subcarriers in the fourth data pilot area, which can be replaced by: 996-tone DRU 1 includes the odd-numbered subcarriers indexed in the first data pilot area, the even-numbered subcarriers indexed in the second data pilot area, the odd-numbered subcarriers indexed in the third data pilot area, and the even-numbered subcarriers indexed in the fourth data pilot area.

[1571] The subcarrier indexes of 996-tone DRU 2 are [-1011:2:-515,-508:2:-12,13:2:509,516:2:1012].

[1572] In the embodiment of the present application, 996-tone DRU 1 or 996-tone DRU 2 is evenly distributed in the four data pilot areas, which is more conducive to channel smoothing and can ensure low PAPR.
