[0021] The technical solution in this application will be described below with reference to the accompanying drawings.

[0022] Communication System

[0023] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as wireless local area networks (WLAN), wireless fidelity (WiFi), high performance radio local area networks (HIPELAN), wide area networks (WAN), cellular networks, or other communication systems. For another example, the technical solutions provided in the embodiments of the present application can be applied to communication systems that adopt the 802.11 standard. For example, the 802.11 standard includes but is not limited to the 802.11ax standard, the 802.11be standard, and the next generation 802.11 standard.

[0024] FIG1 is a schematic diagram of a communication system applicable to embodiments of the present application. Referring to FIG1 , the communication devices in the communication system 100 may include access points (APs) 111 and 112, and stations (STAs) 121 and 122. STA 121 may access the network through AP 111, and STA 122 may access the network through AP 112.

[0025] In some implementations, a STA may establish an association with one or more APs, after which the associated STAs and APs may communicate. For example, as shown in FIG1 , AP 111 and STA 121 may communicate after establishing an association, and AP 112 and STA 122 may communicate after establishing an association.

[0026] In some implementations, the communication in the communication system 100 may be communication between an AP and a non-AP STA, communication between a non-AP STA and a non-AP STA, or communication between a STA and a peer STA, where a peer STA may refer to a device that communicates with the STA peer, for example, the peer STA may be an AP or a non-AP STA.

[0027] It should be understood that FIG1 exemplarily shows two AP STAs and two non-AP STAs, and the communication system 100 may also include a larger number of AP STAs, or the communication system 100 may include other numbers of non-AP STAs, which is not limited in the embodiments of the present application.

[0028] In addition, the above communication system can be applied to scenarios of multi-device collaboration, such as multi-AP (multiple access points, multi-AP) collaboration, or multi-site collaboration.

[0029] In the embodiments of this application, the names of AP and / or STA are not limited. In some scenarios, AP can also be called AP STA, that is, in a sense, AP is also a type of STA. In other scenarios, STA can also be called non-AP STA.

[0030] In some scenarios, the aforementioned communication device may also be a "multi-link device (MLD)," i.e., a device that can communicate via multiple communication links, where the multiple communication links may include communication links in different frequency bands, such as millimeter wave bands and / or low-frequency bands. Generally, if the multi-link device is an AP, the AP may also be referred to as a "multi-link AP." If the multi-link device is a STA, the STA may also be referred to as a "multi-link STA."

[0031] In the embodiment of the present application, the AP can be a device in a wireless network. The AP can be a communication entity such as a communication server, a router, a switch, a bridge, or the AP can include various forms of macro base stations, micro base stations, relay stations, etc. Of course, the AP can also be a chip or circuit or processing system in these various forms of devices, thereby realizing the method and function of the embodiment of the present application. The AP can be applied to a variety of scenarios, such as sensor nodes in smart cities (such as smart water meters, smart electricity meters, 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 AR and VR), smart devices in smart offices (such as printers, projectors, etc.), Internet of Vehicles devices in the Internet of Vehicles, and some infrastructure in daily life scenarios (such as vending machines, self-service navigation counters in supermarkets, self-service checkout devices, self-service ordering machines), etc.

[0032] In some implementations, the role of a STA in a communication system is not absolute; in some scenarios, a STA can function as an AP. For example, when a mobile phone is connected to a router, it can be a non-AP STA, while when it is acting as a hotspot for other phones, it functions as an AP.

[0033] In the embodiments of the present application, a STA in the embodiments of the present application may be a device with wireless transceiver capabilities, such as a device that supports the 802.11 series of protocols and can communicate with an AP or other STAs. For example, a STA is any user communication device that allows a user to communicate with an AP and, in turn, with a WLAN. Examples of STAs include user equipment (UE), mobile station (MS), mobile terminal (MT), access terminal, subscriber unit, subscriber station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device.

[0034] The STA in the embodiment of the present application may also be a device that provides voice / data connectivity to users, such as a handheld device or vehicle-mounted device with wireless connection function. Examples include: mobile phones, tablet computers, laptop computers, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices or other processing devices connected to wireless modems, in-vehicle devices, wearable devices, terminal devices in 5G networks or future-evolved public land mobile communication networks. The terminal equipment in the network (PLMN), etc., is not limited to this in the embodiments of the present application.

[0035] By way of example and not limitation, in the embodiments of this application, the STA may also be a wearable device. Wearable devices, also known as wearable smart devices, are a general term for wearable devices that utilize wearable technology to intelligently design and develop wearable devices for everyday wear, such as glasses, gloves, watches, clothing, and shoes. Examples include smart watches or smart glasses, as well as devices that focus on a specific application function and require integration with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0036] In addition, in the embodiments of the present application, a STA can also be a terminal device in the Internet of Things (IoT) system. The IoT is an important component of the future development of information technology. Its main technical feature is to connect objects to the network through communication technology, thereby realizing an intelligent network that interconnects people and machines and things. In the embodiments of the present application, IoT technology can achieve massive connections, deep coverage, and terminal power saving through narrowband (NB) technology, for example.

[0037] Furthermore, in the embodiments of the present application, a STA may be a device in a connected vehicle system. The communication methods in a connected vehicle system are collectively referred to as V2X (where X represents everything). For example, V2X communication includes vehicle-to-vehicle (V2V) communication, vehicle-to-infrastructure (V2I) communication, vehicle-to-pedestrian (V2P) communication, and vehicle-to-network (V2N) communication.

[0038] In addition, in the embodiment of the present application, STA may also include sensors such as smart printers, train detectors, gas stations, etc., whose main functions include collecting data (part of the terminal equipment), receiving AP control information and downlink data, and sending electromagnetic waves to transmit data to the AP.

[0039] In addition, the AP in the embodiment of the present application may be a device for communicating with a STA. The AP may be a network device in a wireless local area network. The AP may be used to communicate with the STA through the wireless local area network.

[0040] From the perspective of the communication standards supported by the AP, in some implementations, the AP can be a device that supports the 802.11be standard. The AP can also be a device that supports various current and future 802.11 family WLAN standards, such as 802.11ax, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a.

[0041] From the perspective of STA-supported communication standards, in some implementations, non-AP STAs can support the 802.11be standard. Non-AP STAs can also support various current and future 802.11 family wireless local area network (WLAN) standards, including 802.11ax, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a.

[0042] In the embodiments of the present application, there is no limitation on the frequency bands supported by WLAN technology. In some implementations, the frequency bands supported by WLAN technology may include, but are not limited to, low frequency bands (e.g., 2.4 GHz, 5 GHz, 6 GHz) and high frequency bands (e.g., 45 GHz, 60 GHz).

[0043] It should be understood that the specific forms of STA and AP in the embodiments of the present application are not particularly limited and are merely illustrative.

[0044] DRU

[0045] With the development of technology, power spectral density (PSD) limits are becoming increasingly stringent. For example, in the 6 GHz band, for non-AP STAs in the low-power indoor band, the PSD limit is -1 dBm / MHz.

[0046] The RRU has contiguous subcarriers. The RRU transmits low power per subcarrier. This is because the PSD limit is defined per MHz and per STA, and the subcarriers in the RRU are contiguous. Therefore, there are more subcarriers per MHz, and according to the PSD limit, the transmit power per subcarrier is low.

[0047] The DRU has discontinuous subcarriers. In the case of the DRU, there are fewer subcarriers per MHz, or even only one subcarrier per MHz. Therefore, the subcarriers in the DRU can be transmitted at a higher power compared to the RRU. For example, for a 52-tone DRU distributed over 80MHz, there may be only one subcarrier per MHz. However, for a 52-tone RRU, there are approximately 13 subcarriers per MHz. In the 6GHz low-power indoor band, the PSD limit is -1dBm / MHz. Therefore, for a 52-tone RU (approximately 4MHz), the maximum transmission power allowed using an RRU is only about 6dBm, while using a DRU can increase the transmission power by 11dB. This significant increase in transmission power can achieve a higher MCS or achieve a longer transmission distance.

[0048] As shown in Figure 2, STA1, STA2, and STA3 can all use DRUs to increase their transmit power. Compared to using RRUs of the same size, all subcarriers receive higher transmit power, significantly improving overall spectrum efficiency.

[0049] It should be noted that an MRU can also have discontinuous subcarriers, as well as a DMRU. The pre-DRU related technical solutions provided in this application can also be applied to DMRUs. For ease of description, the following description only uses the DRU as an example. If you need to apply the embodiments described below to a DMRU, replace "DRU" with "DMRU."

[0050] DRU subcarrier planning (tone plan)

[0051] A DRU tone plan can be built based on a base RU. For example, a 26-tone RRU can be used as the base RU, and RUs can be distributed across 20MHz, 40MHz, 80MHz, 160MHz, and 320MHz to form a 26-tone DRU. A 52-tone DRU can be constructed from two 26-tone DRUs. A 106-tone DRU can be constructed from four 26-tone DRUs and two subcarriers. A 242-tone DRU can be constructed from nine 26-tone DRUs and eight subcarriers. A 484-tone DRU can be constructed from 18 26-tone DRUs and 16 subcarriers. A 996-tone DRU can be constructed from 37 26-tone DRUs and 34 subcarriers. A 2x996-tone DRU can be constructed from 74 26-tone DRUs and 68 subcarriers.

[0052] Table 1 shows an example of a 20MHz UHR PPDU DRU tone plan.

[0054] It should be noted that some of the contents in Table 1 can be implemented independently. In addition, Table 1 may also include other rows or columns.

[0055] Table 2 is an example of a 40MHz UHR PPDU DRU tone plan.

[0056] Table 2

[0057] It should be noted that some of the contents in Table 2 can be implemented independently. In addition, Table 2 may also include other rows or columns.

[0058] Channel puncturing

[0059] Channel puncturing is also known as preamble puncturing. After a channel is punctured, the punctured portion of the channel cannot transmit signals. In other words, within the PPDU bandwidth, at least one subchannel has no PPDU transmission. The subchannel bandwidth can be 20 MHz. For example, if an 80 MHz PPDU is punctured, one or more 20 MHz subchannels within the 80 MHz bandwidth may not have any signals transmitted.

[0060] Optionally, when a 20 MHz sub-bandwidth in the 80 MHz bandwidth is punctured, one or more RUs can be transmitted on the remaining 60 MHz.

[0061] In some embodiments, 20 MHz / 40 MHz PPDUs do not need to support puncturing.

[0062] The related art and the DRU tone plan described above are for the case of no puncturing. This application proposes a subcarrier index in the DRU tone plan under the case of channel puncturing.

[0063] The embodiment provided in this application is described below by taking the first channel being punctured as an example.

[0064] The first channel may be a channel for transmitting the first PPDU. The bandwidth of the first channel may be the bandwidth of the first PPDU. This application does not limit the bandwidth of the first channel. For example, the bandwidth of the first channel may be an integer multiple of 80 MHz. Exemplarily, the bandwidth of the first channel may be 80 MHz, 160 MHz, 320 MHz, etc.

[0065] The first channel may include one or more first bandwidths. The first bandwidth may be, for example, 80 MHz. Based on this, the DRU tone plan provided in the embodiment of the present application may be completed within each 80 MHz.

[0066] The first channel may be punctured. In other words, one or more sub-channels within the bandwidth of the first PPDU may be punctured. That is, the one or more punctured sub-channels may not transmit signals of the first PPDU.

[0067] One or more first bandwidths in the first channel may be punctured. For example, if the bandwidth of the first channel is 320 MHz or 80 MHz, the first 80 MHz bandwidth in the first channel may be punctured, and / or the second 80 MHz bandwidth in the first channel may be punctured.

[0068] The bandwidth of the punctured sub-channel may be 20 MHz. Taking the first bandwidth as 80 MHz as an example, if 20 MHz of the 80 MHz is punctured, one or more DRUs may transmit on the 60 MHz of the punctured sub-channel.

[0069] This application proposes a DRU tone plan for a first bandwidth. Based on the DRU tone plan for the first bandwidth, a DRU tone plan for a first channel can be obtained.

[0070] In some embodiments, the subcarrier index of the DRU tone plan of the first bandwidth may include a first subcarrier index. The first subcarrier index may be determined based on a second subcarrier index. The second subcarrier index may belong to a subcarrier index of the DRU tone plan of the second bandwidth. The second bandwidth may correspond to a non-punctured channel.

[0071] The second bandwidth may be smaller than the first bandwidth. For example, if the first bandwidth is 80 MHz, the second bandwidth may be 20 MHz or 40 MHz.

[0072] The DRU tone plan of the second bandwidth may include a non-punctured DRU tone plan. The non-punctured DRU tone plan may be a tone plan defined in the relevant art. For example, the DRU tone plan of the second bandwidth may include the tone plans shown in Table 1 and Table 2 mentioned above.

[0073] It should be noted that, in this application, DRU 20MHz It can represent the DRU of non-puncturing mode 20MHz PPDU. 40MHz It can represent the DRU of non-punctured mode 40MHz PPDU.

[0074] Therefore, it can be seen that the subcarrier index in the punctured DRU tone plan proposed in this application can be defined based on the subcarrier index in the non-punctured DRU tone plan. Therefore, this application can simplify the design complexity of the subcarriers of the punctured DRU tone plan.

[0075] In some embodiments, the unpunctured bandwidth of the first bandwidth may include one or more second bandwidths. For example, the one or more second bandwidths may include: one or more 20 MHz and / or one or more 40 MHz. Taking the first bandwidth as 80 MHz as an example, if 20 MHz of the 80 MHz is punctured, one RU or a group of RUs can transmit on the 20 MHz, and another RU or a group of RUs can transmit on the remaining 40 MHz.

[0076] By splitting the unpunctured portion of the first bandwidth into 20MHz and / or 40MHz sections, the subcarrier indices in the punctured DRU tone plan can be designed based on the 20MHz / 40MHz tone plan in the related art, avoiding the design of a 60MHz tone plan that is not available in the related art, thereby simplifying the tone plan design complexity. Furthermore, by splitting the remaining bandwidth after puncturing, the flexibility and gain of the punctured DRU tone plan can be balanced.

[0077] Assuming the first bandwidth is 80MHz, after the 1st, 2nd, 3rd and 4th 20MHz sub-bandwidths in the first bandwidth are punctured, the 80MHz PPDU can be represented by puncturing patterns 0111, 1011, 1101 and 1110, respectively. 1 can represent an unpunctured 20MHz subchannel, and 0 can represent a punctured 20MHz subchannel. The unpunctured bandwidth in the first bandwidth may include 1 20MHz bandwidth and 1 40MHz bandwidth. The position of 1 40MHz bandwidth may correspond to the position of two consecutive 1s; the position of 1 20MHz bandwidth may correspond to the position of the remaining 1. Alternatively, the unpunctured bandwidth in the first bandwidth may include 3 20MHz bandwidths. The positions of 3 20MHz bandwidths may correspond to the positions of 3 1s.

[0078] It should be noted that the sub-bandwidths in the first bandwidth may be arranged in order of frequency from low to high. That is, the frequencies of the first, second, third, and fourth sub-bandwidths in the first bandwidth may be arranged in order of frequency from low to high.

[0079] In some embodiments, the first subcarrier index and the second subcarrier index correspond to the same DRU size, and the first subcarrier index is obtained by shifting or operating the second subcarrier index.

[0080] For example, the shift may include a left shift or a right shift. Exemplarily, the second subcarrier index may be shifted left or right to obtain the first subcarrier index. For another example, the operation may include addition. Exemplarily, the second subcarrier index may be added with a positive or negative number to obtain the first subcarrier index.

[0081] It should be noted that the DRU size may include 26-tone, 52-tone, 106-tone or 242-tone, etc.

[0082] As described above, the first subcarrier index corresponds to the first bandwidth, and the second subcarrier index corresponds to the second bandwidth. By shifting or calculating, the range of the subcarrier index of the second bandwidth can be converted to the range of the subcarrier index of the first bandwidth, so that the first subcarrier index meets the range requirement of the subcarrier index of the first bandwidth.

[0083] As described above, the first bandwidth can be 80 MHz and the second bandwidth can be 20 MHz, that is, the subcarrier index in the 80 MHz punctured DRU tone plan can be determined by the subcarrier index in the 20 MHz non-punctured DRU tone plan. The first case is used as an example for illustration. The first case includes: the first bandwidth is 80 MHz, the second bandwidth is 20 MHz, and the first subcarrier index and the second subcarrier index both correspond to 26 channels.

[0084] Optionally, in the first case, when the first subcarrier index belongs to the first 13 subcarrier indexes of any DRU from DRU10 to DRU18, and the second subcarrier index belongs to the first 13 subcarrier indexes of any DRU from DRU1 to DRU9, the first subcarrier index is obtained based on the second subcarrier index + a1. Where a1 can be an integer. a1 can be greater than 0. Alternatively, a1 can be less than 0.

[0085] Optionally, in the first case, when the first subcarrier index belongs to the last 13 subcarrier indexes of any DRU from DRU10 to DRU18, and the second subcarrier index belongs to the last 13 subcarrier indexes of any DRU from DRU1 to DRU9, the first subcarrier index can be obtained based on the second subcarrier index + a2. Where a2 can be an integer. a2 can be greater than 0. Alternatively, a2 can be less than 0.

[0086] For example, for the case where the puncturing pattern is 0111, the 26-tone DRU 80MHz,0111 The 10-18 tone plan can be supported by the 26-tone DRU in the 20MHz UHR PPDU DRU tone plan. 20MHz The tone indexes 1 to 9 are obtained through certain shifts or operations to form each 26-tone DRU. 80MHz,0111 The first 13 tone indices from 10 to 18. For example, each 26-tone DRU 20MHz The first 13 tone indices from 1 to 9 can be added with a1. Among them, a1 can satisfy a1 = -131. Each 26-tone DRU 20MHzThe last 13 tone indices from 1 to 9 plus a2 form each 26-tone DRU 80MHz,0111 The last 13 tone indexes from 10 to 18. Among them, a2 can satisfy: a2 = -134,

[0087] Optionally, in the first case, when the first subcarrier index belongs to the first 13 subcarrier indices of any DRU from DRU1 to DRU9, and the second subcarrier index belongs to the first 13 subcarrier indices of any DRU from DRU1 to DRU9, the first subcarrier index can be obtained based on the second subcarrier index + b1. Wherein, b1 can be an integer. b1 can be greater than 0. Alternatively, b1 can be less than 0.

[0088] Optionally, in the first case, when the first subcarrier index belongs to the last 13 subcarrier indexes of any DRU from DRU1 to DRU9, and the second subcarrier index belongs to the last 13 subcarrier indexes of any DRU from DRU1 to DRU9, the first subcarrier index can be obtained based on the second subcarrier index + b2. Where b2 can be an integer. b2 can be greater than 0. Alternatively, b2 can be less than 0.

[0089] For example, when the puncturing pattern is 1011, each 26-tone DRU 20MHz The first 13 tone indices from 1 to 9 can be added with b1 to form each 26-tone DRU 80MHz,1011 The first 13 tone indices from 1 to 9. Among them, b1 can satisfy: b1 = -378. For example, each 26-tone DRU 20MHz The last 13 tone indices from 1 to 9 can be added with b2 to form each 26-tone DRU 80MHz,1011 The last 13 tone indices from 1 to 9. Among them, b2 can satisfy: b2 = -381.

[0090] Optionally, in the first case, when the first subcarrier index belongs to the first 13 subcarrier indices of any DRU from DRU29 to DRU37, and the second subcarrier index belongs to the first 13 subcarrier indices of any DRU from DRU1 to DRU9, the first subcarrier index can be obtained based on the second subcarrier index + c2. Wherein, c2 can be an integer. c2 can be greater than 0. Alternatively, c2 can be less than 0.

[0091] Optionally, in the first case, when the first subcarrier index belongs to the last 13 subcarrier indexes of any DRU from DRU29 to DRU37, and the second subcarrier index belongs to the last 13 subcarrier indexes of any DRU from DRU1 to DRU9, the first subcarrier index can be obtained based on the second subcarrier index + c3. Wherein, c3 can be an integer. c3 can be greater than 0. Alternatively, c3 can be less than 0.

[0092] For example, when the puncturing pattern is 1101, each 26-tone DRU 20MHz The first 13 tone indices from 1 to 9 can be added with c2 to form each 26-tone DRU 80MHz,1101 The first 13 tone indices from 29 to 37. Among them, c2 can satisfy: c2 = 381. Each 26-tone DRU 20MHz The last 13 tone indices from 1 to 9 can be added with c3 to form each 26-tone DRU 80MHz,1101 The last 13 tone indices from 29 to 37, where c3 can satisfy c3 = 378, are shown in Table 11.

[0093] Optionally, in the first case, when the first subcarrier index belongs to the first 13 subcarrier indexes of any DRU from DRU20 to DRU28, and the second subcarrier index belongs to the first 13 subcarrier indexes of any DRU from DRU1 to DRU9, the first subcarrier index can be obtained based on the second subcarrier index + d1. d1 can be an integer. d1 can be greater than 0. Alternatively, d1 can be less than 0.

[0094] Optionally, in the first case, when the first subcarrier index belongs to the last 13 subcarrier indexes of any DRU from DRU20 to DRU28, and the second subcarrier index belongs to the last 13 subcarrier indexes of any DRU from DRU1 to DRU9, the first subcarrier index can be obtained based on the second subcarrier index + d2. d2 can be an integer. d2 can be greater than 0. Alternatively, d2 can be less than 0.

[0095] For example, when the puncture pattern is 1110, each 26-tone DRU 20MHz The first 13 tone indices from 1 to 9 can be added with d1 to form each 26-tone DRU 80MHz,1110 The first 13 tone indices from 20 to 28. Among them, d1 can satisfy: d1 = 134. For example, each 26-tone DRU 20MHzThe last 13 tone indices from 1 to 9 can be added with d2 to form each 26-tone DRU 80MHz,1110 The last 13 tone indices from 20 to 28. Among them, d2 can satisfy: d2 = 131. As shown in Table 15.

[0096] It should be noted that this application does not limit the values ​​of one or more of a1, a2, b1, b2, c2, c3, d1, and d2. For example, one or more of the following may be satisfied: a1 = -131; a1 = -133; a2 = -134; a2 = -132; b1 = -378; b1 = -380; b2 = -381; b2 = -379; c2 = 381; c2 = 379; c3 = 378; c3 = 380; d1 = 134; d1 = 132; d2 = 131; d2 = 133.

[0097] As described above, the first bandwidth can be 80 MHz and the second bandwidth can be 40 MHz. That is, the subcarrier index in the 80 MHz punctured DRU tone plan can be determined by the subcarrier index in the 40 MHz non-punctured DRU tone plan. The second case is used as an example for illustration. The second case includes: the first bandwidth is 80 MHz, the second bandwidth is 40 MHz, and the first subcarrier index and the second subcarrier index both correspond to 26 channels.

[0098] Optionally, in the second case, when the first subcarrier index belongs to the subcarrier index of any DRU from DRU1 to DRU18, and the second subcarrier index belongs to the subcarrier index of any DRU from DRU1 to DRU18, the first subcarrier index can be obtained based on the second subcarrier index + c1. Where c1 can be an integer. c1 can be greater than 0. Alternatively, c1 can be less than 0.

[0099] For example, when the puncturing pattern is 1101 or 1110, the DRU tone plan of each 40MHz UHR PPDU has a 26-tone DRU. 40MHz Tone indexes 1 to 18 can be added to c1 to form each 26-tone DRU 80MHz,1101 Tone index from 1 to 18. Where c1 can satisfy: c1 = -256.

[0100] Optionally, in the second case, when the first subcarrier index belongs to the subcarrier index of any DRU from DRU20 to DRU37, and the second subcarrier index belongs to the subcarrier index of any DRU from DRU1 to DRU18, the first subcarrier index can be obtained based on the second subcarrier index + a3. Wherein, a3 can be an integer. a3 can be greater than 0. Alternatively, a3 can be less than 0.

[0101] For example, when the puncturing pattern is 0111 or 1011, the DRU tone plan of each 40MHz UHR PPDU has 26-tone DRUs. 40MHz Add a3 to the tone index from 1 to 18 to form each 26-tone DRU 80MHz,0111 Tone index 20 to 37. Among them, a3 can satisfy a3 = 256.

[0102] It should be noted that a1, a2, a3, b1, b2, c1, c2, c3, d1, and d2 can all be referred to as shift parameters. This application does not limit the values ​​of one or more of a1, a2, a3, b1, b2, c1, c2, c3, d1, and d2. That is, this application does not limit the values ​​of the shift parameters. For example, one or more of the following may satisfy: a1 = -131; a1 = -133; a2 = -134; a2 = -132; b1 = -378; b1 = -380; b2 = -381; b2 = -379; c2 = 381; c2 = 379; c3 = 378; c3 = 380; d1 = 134; d1 = 132; d2 = 131; d2 = 133. For another example, a3=256; and / or c1=-256.

[0103] The values ​​of one or more of a1, a2, a3, b1, b2, c1, c2, c3, d1 and d2 can be determined based on the range of subcarrier indices of the first bandwidth and / or the range of subcarrier indices of the second bandwidth.

[0104] For example, for a 26-tone DRU, DRU 20MHz The 13 tones on the left can be aligned to the left of the 20MHz unpunctured portion of the 80MHz bandwidth; 20MHz The 13 tones on the right side of the image can be aligned to the right of the unpunctured 20 MHz subcarrier in the 80 MHz bandwidth.

[0105] For example, for the 0111 puncturing pattern, if the subcarrier index range of the second 20 MHz in the 80 MHz band is [-253:-12], and the subcarrier index range of the 20 MHz DRU tone plan is [-122:122], then a1 = -131, a2 = -134. That is, -122 + (-131) = -253; 122 + (-134) = -12. If the subcarrier index range of the second 20 MHz in the 80 MHz band is [-253:-12], and the subcarrier index range of the 20 MHz DRU tone plan is [-120:120], then a1 = -133, a2 = -132. That is, -120 + (-133) = -253; 120 + (-132) = -12.

[0106] For example, for the 1011 puncturing pattern, if the subcarrier index range of the first 20 MHz in 80 MHz is [-500:-259], and the subcarrier index range of the 20 MHz DRU tone plan is [-122:122], then b1 = -378, b2 = -381. That is, -122 + (-378) = -500; 122 + (-381) = -259. If the subcarrier index range of the first 20 MHz in 80 MHz is [-500:-259], and the subcarrier index range of the 20 MHz DRU tone plan is [-120, 120], then b1 = -380, b2 = -379. That is, -120 + (-380) = -500; 120 + (-379) = -259.

[0107] For example, for the 1101 puncturing pattern, if the subcarrier index of the fourth 20 MHz band in the 80 MHz band is in the range [259:500], and the subcarrier index of the 20 MHz DRU tone plan is in the range [-122:122], then c2 = 381 and c3 = 378. That is, -122 + (381) = 259; 122 + (378) = 500. If the subcarrier index of the fourth 20 MHz band in the 80 MHz band is in the range [259:500], and the subcarrier index of the 20 MHz DRU tone plan is in the range [-120:120], then c2 = 379 and c3 = 380. That is, -120 + (379) = 259; 120 + (380) = 500.

[0108] For example, for the 1110 puncturing pattern, if the range of the third 20 MHz subcarrier index in 80 MHz is [12:253], and the subcarrier index range of the 20 MHz DRU tone plan is [-122:122], then d1 = 134, d2 = 131. That is, -122 + (134) = 12; 122 + (131) = 253. If the range of the third 20 MHz subcarrier index in 80 MHz is [12:253], and the subcarrier index range of the 20 MHz DRU tone plan is [-120:120], then d1 = 132, d2 = 133. That is, -120 + (132) = 12; 120 + (133) = 253.

[0109] For example, for the 0111 puncturing pattern or the 1011 puncturing pattern, if the second 40 MHz subcarrier index in the 80 MHz band is in the range of [12:253,259:500], and the subcarrier index range of the 40 MHz DRU tone plan is [-244:-3,3:244], then a3 = 256. That is, -244 + (256) = 12; 244 + (256) = 500.

[0110] For example, for the 1101 puncturing mode or the 1110 puncturing mode, if the first 40 MHz subcarrier index range in the 80 MHz band is [-500:-259,-253:-12], and the subcarrier index range of the 40 MHz DRU tone plan is [-244:-3,3:244], then c1 = -256. That is, -244 + (-256) = -500; 244 + (-256) = -12.

[0111] In some embodiments, the first subcarrier may belong to a subcarrier index of a first DRU size. The subcarrier index of the first DRU size of the first bandwidth may be determined by: a subcarrier index of a second DRU size of the first bandwidth. Alternatively, the subcarrier index of the first DRU size of the first bandwidth may be determined by: a subcarrier index of the second DRU size of the first bandwidth, and one or more additional subcarrier indexes, wherein the additional subcarrier index may include the second subcarrier index.

[0112] The first DRU size can be larger than the second DRU size. In other words, the subcarrier index of the large-size DRU can be determined by the subcarrier index of the small-size DRU. In other words, the subcarrier index of the large-size DRU can be determined based on the small-size DRU. For example, the first DRU size can be 52 channels, and the second DRU size can include 26 channels. For another example, the first DRU size can be 106 channels, and the second DRU size can include 52 channels. For another example, the first DRU size can be 242 channels, and the second DRU size can include 106 channels or 26 channels.

[0113] It should be noted that the subcarrier index of the second DRU size of the first bandwidth may belong to the subcarrier index of the punctured DRU tone plan.

[0114] In some embodiments, the subcarrier index of the first DRU size of the first bandwidth may include: a plurality of subcarrier indexes of the second DRU size corresponding to the first bandwidth

[0115] For example, an 80 MHz 52-tone subcarrier index can be composed of two 80 MHz 26-tone subcarrier indexes.

[0116] For example, in the case of the puncturing pattern 0111, the 52-tone DRU 80MHz,0111 5-tone plan can be composed of 26-tone DRU 80MHz,0111 10~11 composition. 52-tone DRU 80MHz,0111 6 possible tone plans by 26-tone DRU 80MHz,0111 12~13 composition. 52-tone DRU 80MHz,0111 7-tone plan can be composed of 26-tone DRU 80MHz,0111 15~16 composition. 52-tone DRU 80MHz,0111 8-tone plan can be composed of 26-tone DRU 80MHz,0111 17~18 composition. 52-tone DRU 80MHz,0111 9-tone plan can be composed of 26-tone DRU 80MHz,0111 20~21 composition. 52-tone DRU 80MHz,0111 10-tone plan can be composed of 26-tone DRU 80MHz,0111 22~23 composition. 52-tone DRU 80MHz,0111 11 tone plan can be composed of 26-tone DRU 80MHz,0111 25~26 composition. 52-tone DRU 80MHz,011112-tone plan can be composed of 26-tone DRU 80MHz,0111 27~28 composition. 52-tone DRU 80MHz,0111 13 tone plan can be composed of 26-tone DRU 80MHz,0111 29~30 composition. 52-tone DRU 80MHz,0111 14-tone plan can be composed of 26-tone DRU 80MHz,0111 31~32 composition. 52-tone DRU 80MHz,0111 15-tone plan can be composed of 26-tone DRU 80MHz,0111 34~35 composition. 52-tone DRU 80MHz,0111 A 16-tone plan can be composed of a 26-tone DRU 80MHz,0111 Consists of 36 to 37.

[0117] For example, in the case of punching mode 1011, 52-tone DRU 80MHz,1011 1 tone plan can be composed of 26-tone DRU 80MHz,1011 1~2 composition. 52-tone DRU 80MHz,1011 2 tone plan can be composed of 26-tone DRU 80MHz,1011 3~4 composition. 52-tone DRU 80MHz,1011 3 tone plan can be composed of 26-tone DRU 80MHz,1011 6~7 composition. 52-tone DRU 80MHz,1011 4-tone plan can be composed of 26-tone DRU 80MHz,1011 8~9 composition. 52-tone DRU 80MHz,1011 9-16 tone plan and 106-tone DRU with punch pattern 0111 80MHz,0111 The tone plan for 9 to 16 is the same.

[0118] For example, in the case of punching mode 1101, 52-tone DRU 80MHz,1101 1 tone plan can be composed of 26-tone DRU 80MHz,1101 1~2 composition. 52-tone DRU 80MHz,1101 2 tone plan can be composed of 26-tone DRU 80MHz,1101 3~4 composition. 52-tone DRU 80MHz,1101 3 tone plan can be composed of 26-tone DRU80MHz,1101 6~7 composition. 52-tone DRU 80MHz,1101 4-tone plan can be composed of 26-tone DRU 80MHz,1101 8~9 composition. 52-tone DRU 80MHz,1101 5-tone plan can be composed of 26-tone DRU 80MHz,1101 10~11 composition. 52-tone DRU 80MHz,1101 6-tone plan can be composed of 26-tone DRU 80MHz,1101 12~13 composition. 52-tone DRU 80MHz,1101 7-tone plan can be composed of 26-tone DRU 80MHz,1101 15~16 composition. 52-tone DRU 80MHz,1101 8-tone plan can be composed of 26-tone DRU 80MHz,1101 17~18 composition. 52-tone DRU 80MHz,1101 13 tone plan can be composed of 26-tone DRU 80MHz,1101 29~30 composition. 52-tone DRU 80MHz,1101 14-tone plan can be composed of 26-tone DRU 80MHz,1101 31~32 composition. 52-tone DRU 80MHz,1101 15-tone plan can be composed of 26-tone DRU 80MHz,1101 34~35 composition. 52-tone DRU 80MHz,1101 A 16-tone plan can be composed of a 26-tone DRU 80MHz,1101 Consists of 36 to 37.

[0119] For example, in the case of punching mode 1110, 52-tone DRU 80MHz,1110 1 to 8 tone plan and 52-tone DRU with punch pattern 1101 80MHz,1101 The tone plans 1 to 8 are the same. 52-tone DRU 80MHz,1110 9-tone plan can be composed of 26-tone DRU 80MHz,1110 20~21 composition. 52-tone DRU 80MHz,1110 10-tone plan can be composed of 26-tone DRU 80MHz,1110 22~23 composition. 52-tone DRU 80MHz,1110 11 tone plan can be composed of 26-tone DRU80MHz,1110 25~26 composition. 52-tone DRU 80MHz,1110 12-tone plan can be composed of 26-tone DRU 80MHz,1110 27-28 composition.

[0120] In some embodiments, the subcarrier index of the first DRU size of the first bandwidth may include: multiple subcarrier indices of the second DRU size corresponding to the first bandwidth, and one or more third subcarrier indices. The first subcarrier index may belong to one or more third subcarrier indices. The bandwidth and / or DRU size of the third subcarrier index may be different from the subcarrier index of the second DRU size of the first bandwidth. Therefore, compared with the subcarrier index of the second DRU size of the first bandwidth, the third subcarrier index may also be referred to as an "additional subcarrier index."

[0121] For example, the first bandwidth is 80MHz, the second bandwidth is 20MHz, and when the first DRU size is 106 channels and the second DRU size is 52 channels, the subcarrier index of the first DRU size of the first bandwidth includes: multiple indices of subcarriers of the second DRU size of the first bandwidth and two third subcarrier indices; if the first subcarrier index is the index with the lower frequency among the two third subcarrier indices, the first subcarrier is obtained based on the second subcarrier + e1; if the first subcarrier index is the index with the higher frequency among the two third subcarrier indices, the first subcarrier is obtained based on the second subcarrier + e2; wherein the values ​​of e1 and e2 are different. Exemplarily, e1 = a1, and / or, e2 = a2. For example, e1 can satisfy: e1 = -131; or e1 = -133. For another example, e1 can satisfy: e2 = -134; or e2 = -132.

[0122] For example, in the case of puncturing pattern 0111, 106-tone DRU 80MHz,0111 3 tone plan can be composed of 52-tone DRU 80MHz,0111 5-6 and 2 additional tones. 106-tone DRU 80MHz,0111 4-tone plan can be composed of 52-tone DRU 80MHz,0111 7~8 and an additional 2 tones. Each 106-tone DRU 80MHz,0111 The additional 2 tones in 3 and 4 can be used to form a 106-tone DRU by each of the DRU tone plans of the 20MHz UHR PPDU. 20MHz The extra two tone indices in 1 to 2 can be obtained by some shift or operation. For example, in each 106-tone DRU 20MHzFor the additional two tones in 1-2, the smaller tone index is added with a1, and the larger tone index is added with a2, forming each 106-tone DRU 80MHz,0111 The additional two tones in 3 and 4, where a1 and a2 can be the same as described above, are shown in Table 5. 106-tone DRU 80MHz,0111 5-tone plan can be composed of 52-tone DRU 80MHz,0111 9~10 and 2 additional tones. 106-tone DRU 80MHz,0111 6-tone plan can be composed of 52-tone DRU 80MHz,0111 11~12 and 2 additional tones. 106-tone DRU 80MHz,0111 7 tone plan can be composed of 52-tone DRU 80MHz,0111 13~14 and 2 additional tones. 106-tone DRU 80MHz,0111 8-tone plan can be composed of 52-tone DRU 80MHz,0111 15 to 26 and an additional 2 tones.

For example, each 106-tone DRU 40MHz The tone index of the additional two tones 1 to 4 is added to a3 to form each 106-tone DRU 80MHz,0111 The additional two tones from 5 to 8. The value of a3 can be as described above.

[0123] For example, in the case of puncturing pattern 0111, 242-tone DRU 80MHz,0111 3 tone plan can be composed of 106-tone DRU 80MHz,0111 5-6, 26-tone DRU 80MHz,0111 24 and an additional 4 tones. 242-tone DRU 80MHz,0111 4 tone plan can be composed of 106-tone DRU 80MHz,0111 7~8、26-tone DRU 80MHz,0111 33 and an additional 4 tones. Each 242-tone DRU 80MHz,0111The additional 4 tones in 3-4 can be provided by each 242-tone DRU in the DRU tone plan of the 40MHz UHR PPDU. 40MHz The extra 4 tone indices in 1 to 2 are obtained through certain shifts or operations. For example, in each 242-tone DRU 40MHz The tone index of the additional 4 tones in 1-2 plus a3 constitutes each 242-tone DRU 80MHz,0111 The additional 4 tones from 3 to 4. The value of a3 can be as described above.

[0124] For example, in the case of punching mode 1011, 106-tone DRU 80MHz,1011 1 tone plan can be composed of 52-tone DRU 80MHz,1011 1~2 and an additional 2 tones. 106-tone DRU 80MHz,1011 2 tone plan can be composed of 52-tone DRU 80MHz,1011 3~4 and an additional 2 tones. Each 106-tone DRU 80MHz,1011 The additional two tones in 1 and 2 can be provided by each 106-tone DRU in the DRU tone plan of the 20MHz UHR PPDU. 20MHz The extra two tone indices in 1 to 2 are obtained by a certain shift or operation. For example, in each 106-tone DRU 20MHz For the additional two tones in 1-2, the smaller tone index is added with b1, and the larger tone index is added with b2, forming each 106-tone DRU 80MHz,1011 The additional two tones in 1 and 2. The values ​​of b1 and b2 can be as described above. See Table 9. 106-tone DRU 80MHz,1011 106-tone DRU with 5-8 tone plan and punch pattern 0111 80MHz,0111 The tone plans for 5 to 8 are the same.

[0126] For example, in the case of punching mode 1101, 106-tone DRU 80MHz,1101 1 tone plan can be composed of 52-tone DRU 80MHz,1101 1~2 and an additional 2 tones. 106-tone DRU 80MHz,1101 2 tone plan can be composed of 52-tone DRU 80MHz,1101 3~4 and 2 additional tones. 106-tone DRU 80MHz,1101 3 tone plan can be composed of 52-tone DRU 80MHz,1101 5-6 and 2 additional tones. 106-tone DRU 80MHz,1101 4-tone plan can be composed of 52-tone DRU 80MHz,1101 7~8 and an additional 2 tones. Each 106-tone DRU 80MHz,1101 The additional 2 tones 1 to 4 can be provided by each 106-tone DRU in the DRU tone plan of the 40MHz UHR PPDU. 40MHz The extra two tone indices in 1 to 4 are obtained through a certain shift or operation. For example, each 106-tone DRU 40MHz The tone index of the additional two tones in 1 to 4 plus c1 constitutes each 106-tone DRU 80MHz,1101 The additional two tones 1 to 4. The value of c1 can be as described above. See Table 12. 106-tone DRU 80MHz,1101 7 tone plan can be composed of 52-tone DRU 80MHz,1101 13~14 and 2 additional tones. 106-tone DRU 80MHz,1101 8-tone plan can be composed of 52-tone DRU 80MHz,1101 15~16 and an additional 2 tones. Each 106-tone DRU 80MHz,1101 The additional 2 tones 7 and 8 can be provided by each 106-tone DRU in the DRU tone plan of the 20MHz UHR PPDU. 20MHz The extra two tone indices in 1 to 2 are obtained by a certain shift or operation. For example, in each 106-tone DRU 20MHzFor the additional two tones in 1-2, the smaller tone index is added to c2, and the larger tone index is added to c3, for example, c3 = 378, forming each 106-tone DRU 80MHz,1101 The additional two tones in 7 and 8. The value of c2 can be as described above, as shown in Table 13.

[0127] For example, in the case of punching mode 1101, 242-tone DRU 80MHz,1101 1 tone plan can be composed of 106-tone DRU 80MHz,1101 1~2, 26-tone DRU 80MHz,1101 5 and an additional 4 tones. 242-tone DRU 80MHz,1101 2 tone plan can be composed of 106-tone DRU 80MHz,1101 3~4, 26-tone DRU 80MHz,1101 14 and an additional 4 tones. Each 242-tone DRU 80MHz,1101 The additional 4 tones in 1 and 2 can be provided by each 242-tone DRU in the DRU tone plan of the 40MHz UHR PPDU. 40MHz The extra 4 tone indices in 1 to 2 are obtained through certain shifts or operations. For example, in each 242-tone DRU 40MHz The tone indices of the additional 4 tones in 1-2 plus c1 form each 242-tone DRU 80MHz,1101 The additional 4 tones in 1 and 2. The value of c1 can be as described above, as shown in Table 14.

[0128] For example, in the case of punching mode 1110, 106-tone DRU 80MHz,1110 Tone plans 1 to 4 can be used with the 106-tone DRU of punch pattern 1101. 80MHz,1101 Tone plans 1 to 4 are the same, as shown in Table 12. 106-tone DRU 80MHz,1110 5-tone plan can be composed of 52-tone DRU 80MHz,1110 9~10 and 2 additional tones. 106-tone DRU 80MHz,1110 6-tone plan can be composed of 52-tone DRU 80MHz,1110 11~12 and an additional 2 tones. Each 106-tone DRU 80MHz,1110The additional 2 tones 5 and 6 can be provided by each 106-tone DRU in the DRU tone plan of the 20MHz UHR PPDU. 20MHz The extra two tone indices in 1 to 2 are obtained through a certain shift or operation. For example, in each 106-tone DRU 20MHz For the additional two tones in 1-2, the smaller tone index is added with d1, and the larger tone index is added with d2, forming each 106-tone DRU 80MHz,1110 The additional two tones in 5 and 6. The values ​​of d1 and d2 can be as described above.

[0129] For example, in the case of punching mode 1110, 242-tone DRU 80MHz,1110 242-tone DRU with 1-2 tone plan and punch pattern 1101 80MHz,1101 The tone plans 1 and 2 are the same.

[0130] As described above, based on the DRU tone plan of the first bandwidth, the DRU tone plan of the first channel may be determined.

[0131] In some embodiments, when the bandwidth of the first channel is equal to the first bandwidth (for example, both are 80 MHz), the subcarrier index of the DRU subcarrier planning of the first channel may include the first subcarrier index. That is, when the bandwidth of the first channel is equal to the first bandwidth, the first subcarrier index determined by the technical solution described above can be used as a subcarrier index in the DRU subcarrier planning of the first channel. That is, the tone plan of the first channel can be the tone plan of the first bandwidth.

[0132] In some embodiments, when the bandwidth of the first channel is greater than the first bandwidth, the subcarrier index of the DRU subcarrier planning of the first channel can be determined by shifting or calculating the subcarrier index of the DRU subcarrier planning of the first bandwidth.

[0133] Optionally, when the bandwidth of the first channel is 160MHz and the first bandwidth is 80MHz, the first channel may include a first 80MHz subblock and a second 80MHz subblock. The frequency of the first 80MHz subblock may be lower than the frequency of the second 80MHz subblock. When the first 80MHz subblock is punctured, the subcarrier index of the DRU subcarrier planning of the first 80MHz subblock may be determined by: the subcarrier index of the DRU subcarrier planning of the first bandwidth + f1; when the second 80MHz subblock is punctured, the subcarrier index of the DRU subcarrier planning of the second 80MHz subblock may be determined by: the subcarrier index of the DRU subcarrier planning of the first bandwidth + f2. Wherein, f1 and f2 are both integers.

[0134] It should be noted that this application does not limit the values ​​of f1 and f2. The values ​​of f1 and f2 can be determined according to the range of the 160MHz subcarrier index. For example, f1 = -512. For another example, f2 = 512.

[0135] It should be noted that this application does not limit whether the non-punctured 80 MHz sub-block is transmitted through the DRU. For example, the non-punctured 80 MHz sub-block can be transmitted through the DRU or the RRU.

[0136] For example, when a 160MHz UHR PPDU is transmitted using a mixture of DRU and RRU, from low to high frequency, if the first 80MHz subblock is transmitted using DRU and there is a 20MHz puncture in the 80MHz subblock, the tone index in the DRU tone plan of the first 80MHz subblock can be the tone index of the first bandwidth tone plan proposed above minus 512. If the second 80MHz subblock is transmitted using DRU and there is a 20MHz puncture in the 80MHz subblock, the tone index in the DRU tone plan of the second 80MHz subblock can be the tone index of the first bandwidth tone plan proposed above plus 512.

[0137] In some embodiments, when the bandwidth of the first channel is 320 MHz and the first bandwidth is 80 MHz, the first channel includes a first 80 MHz sub-block, a second 80 MHz sub-block, a third 80 MHz sub-block and a fourth 80 MHz sub-block, and the frequency of the first 80 MHz sub-block, the frequency of the second 80 MHz sub-block, the frequency of the third 80 MHz sub-block and the frequency of the fourth 80 MHz sub-block are arranged from low to high, and one or more of the following are satisfied: when the first 80 MHz sub-block is punctured, the subcarrier index of the DRU subcarrier planning of the first 80 MHz sub-block is determined by: the subcarrier index of the DRU subcarrier planning of the first bandwidth The subcarrier index of the DRU subcarrier planning of the second 80MHz subblock is determined by the following: the subcarrier index of the DRU subcarrier planning of the first bandwidth + g2; if the third 80MHz subblock is punctured, the subcarrier index of the DRU subcarrier planning of the third 80MHz subblock is determined by the following: the subcarrier index of the DRU subcarrier planning of the first bandwidth + g3; if the fourth 80MHz subblock is punctured, the subcarrier index of the DRU subcarrier planning of the fourth 80MHz subblock is determined by the following: the subcarrier index of the DRU subcarrier planning of the first bandwidth + g4. Wherein, g1, g2, g3 and g4 are all integers.

[0138] It should be noted that this application does not limit the values ​​of g1, g2, g3, and g4. The values ​​of g1, g2, g3, and g4 can be determined based on the range of the 320 MHz subcarrier index. For example, g1 = -1536. For another example, g2 = -512. For another example, g3 = 512. For another example, g4 = 1536.

[0139] It should be noted that this application does not limit whether the non-punctured 80 MHz sub-block is transmitted through the DRU. For example, the non-punctured 80 MHz sub-block can be transmitted through the DRU or the RRU.

[0140] When a 320MHz UHR PPDU is transmitted using a mixture of DRUs and RRUs, from low to high frequency, if the first 80MHz subblock uses a DRU and there is a 20MHz puncture in the 80MHz subblock, the tone index in the DRU tone plan of the first 80MHz subblock can be the tone index of the first bandwidth tone plan mentioned above minus 1536. If the second 80MHz subblock uses a DRU and there is a 20MHz puncture in the 80MHz subblock, the tone index in the DRU tone plan of the second 80MHz subblock can be the tone index of the first bandwidth tone plan mentioned above minus 512. If the third 80MHz subblock uses a DRU and there is a 20MHz puncture in the 80MHz subblock, the tone index in the DRU tone plan of the third 80MHz subblock can be the tone index of the first bandwidth tone plan mentioned above plus 512. If the fourth 80MHz subblock uses a DRU and there is a 20MHz preamble puncturing in the 80MHz subblock, the tone index in the DRU tone plan of the fourth 80MHz subblock can be the tone index of the first bandwidth tone plan mentioned above plus 1536.

[0141] It should be noted that the DRU tone plan for the first bandwidth after puncturing can also be obtained through redesign, but the implementation complexity is higher. For example, the 80MHz DRU tone plan after puncturing can be redesigned to combine the subcarriers in the 20MHz and 40MHz subchannels into 60MHz and perform DRU subcarrier mapping.

[0142] It should be noted that the 80MHz DRU tone plan with punctured channels proposed in this application may not define a 26-tone DRU to maintain consistency with the non-punctured 80MHz DRU tone plan. This is because, in a non-punctured 80MHz channel, both a 26-tone DRU and a 52-tone DRU can achieve 1 tone / MHz, but the power of a 52-tone DRU is 3dB higher than that of a 26-tone DRU.

[0143] It should be noted that the first PPDU can be transmitted through the DRU on the first channel. Alternatively, the first PPDU can be transmitted through a mixture of DRU and RRU on the first channel. For example, when the first channel is 80MHz, when a 20MHz sub-channel in the 80MHz channel is punctured, the remaining 1 non-punctured 20MHz channel can be transmitted using the DRU or RRU, and the remaining 1 non-punctured 40MHz channel can be transmitted using the DRU or RRU. For another example, as mentioned above, when the first channel is 320MHz or 160MHz, the PPDU can be transmitted through a mixture of DRU and RRU.

[0144] The present application is described in detail below through Examples 1 to 4. For an 80MHz PPDU, when the punctured sub-channels are 1, 2, 3, and 4 respectively, Examples 1 to 4 provide tone plans.

[0145] Example 1

[0146] Example 1 proposes a corresponding DRU tone plan for the puncturing pattern 0111.

[0147] Puncturing mode 0111 may refer to a scenario where the first 20 MHz sub-channel within the 80 MHz PPDU transmission bandwidth is punctured. 80MHz,0111 Indicates the DRU corresponding to the puncturing pattern 0111.

[0151] Optionally, 26-tone DRU 80MHz,0111 The 10-18 tone plan can be supported by the 26-tone DRU in the 20MHz UHR PPDU DRU tone plan. 20MHz The tone indexes 1 to 9 are obtained through certain shifts or operations to form each 26-tone DRU. 80MHz,0111 The first 13 tone indices from 10 to 18. For example, each 26-tone DRU 20MHzThe first 13 tone indices from 1 to 9 can be added with a1. Among them, a1 can satisfy a1 = -131. Each 26-tone DRU 20MHz The last 13 tone indices from 1 to 9 plus a2, for example a2 = -134, constitute each 26-tone DRU 80MHz,0111 The last 13 tone indices from 10 to 18 are shown in Table 3.

For example, the DRU tone plan of each 40MHz UHR PPDU is 26-tone DRU. 40MHz The tone index from 1 to 18 plus a3, for example a3 = 256, constitutes each 26-tone DRU 80MHz,0111 Tone index 20 to 37.
