Communication method and device, and computer-readable storage medium

Abstract

The embodiments of the present disclosure provide a communication method and a communication device, a storage medium, and a program product. According to the communication method of the present disclosure, a physical layer protocol data unit (PPDU) is transmitted or received based on a tone plan of a first bandwidth. The tone plan includes a physical resource unit (PRU), and the PRU includes discrete subcarriers. According to the embodiments of the present disclosure, an original nominal RU is processed to obtain a PRU including discrete subcarriers. The discretized subcarriers of the PRU can be evenly distributed to a larger bandwidth without changing the subcarrier division of the original nominal RU. If it is guaranteed that the discrete subcarriers do not cause a large PAPR in data transmission, the transmitting end can communicate with a high transmission power.

Description

[Technical Field]

[0001] TECHNICAL FIELD Embodiments of the present disclosure relate generally to the field of communications, and more particularly to tone plan methods and apparatus, storage media, and program products. [Background technology]

[0002] Wireless local area network (WLAN) technology has evolved through multiple generations, from 802.11a / g, 802.11n, 802.11ac, and 802.11ax standards to the 802.11be standard, where data throughput has continually increased. As such, the 802.11ax standard is sometimes referred to as a high-efficiency (HE) wireless standard, and the 802.11be standard is sometimes referred to as an extremely high-throughput (EHT) wireless standard.

[0003] Regarding bandwidth configurations, the 802.11ax standard currently supports the following bandwidth configurations: 20 MHz, 40 MHz, 80 MHz, 160 MHz, and 80 + 80 MHz. The difference between the 160 MHz and 80 + 80 MHz bandwidth configurations is that the 160 MHz bandwidth is a continuous frequency band, while two 80 MHz bandwidths may be separated. The 802.11be standard supports larger and more flexible bandwidth configurations, such as 240 MHz / 160 + 80 MHz and 320 MHz / 160 + 160 MHz. As the bandwidth increases, the maximum transmit power of communication devices also increases accordingly. The maximum transmit power and maximum power spectral density of communication devices are limited by relevant laws and regulations in various countries. Compared to the maximum transmit power, the maximum power spectral density is more strictly restricted. The maximum allowable transmit power is generally more limited by the power spectral density. For a particular bandwidth, a communication device can usually only communicate at a power lower than the maximum transmit power due to maximum power spectral density limitations. Summary of the Invention

[0239] Herein, a:b:c denotes subcarrier indexes from index a to index c by using b as the step.

[0240] Referring to the twenty-ninth implementation of the first aspect, the pilot subcarrier indices in the first PRU are {-980, -872, -758, -624, -494, -266, -152, -44, 86, 220, 334, 494, 598, 732, 846, 912}, and the pilot subcarrier indices in the second PRU are {-1006, -846, -732, -556, -426, -360, -178, -18, 112, 246, 266, 360, 556, 624, The pilot subcarrier indices in the first PRU are {-938, -804, -664, -530, -468, -400, -246, -112, 44, 178, 292, 426, 530, 690, 778, 872}, and the pilot subcarrier indices in the fourth PRU are {-912, -778, -690, -598, -334, -292, -220, -86, 18, 152, 400, 468, 664, 758, 980, 1006}.

[0241] In a thirtieth implementation of the first aspect, the PPDU is transmitted or received over a total bandwidth of 320 MHz. The total bandwidth includes a first portion of the bandwidth, a second portion of the bandwidth, a third portion of the bandwidth, and a fourth portion of the bandwidth, each of which is 80 MHz. Each of the first portion of the bandwidth, the second portion of the bandwidth, the third portion of the bandwidth, and the fourth portion of the bandwidth includes a PRU based on a tone plan corresponding to the first bandwidth.

[0242] In a thirty-first implementation of the first aspect, the PPDU is transmitted or received over a total bandwidth of 320 MHz.

[0243] According to the communication solution of the present disclosure, the subcarriers of the virtual resource unit (VRU) are distributed discretely over a larger bandwidth to form a PRU, thereby allowing the transmitting end device to transmit data with high transmission power. Furthermore, the discretized subcarriers are evenly distributed over the bandwidth for each segment, ensuring that the discrete subcarriers of the VRU do not cause a large PAPR increase in data transmission. In the above-described subcarrier division solution, the LTF (long training field) field corresponding to each user can have a low PAPR.

Therefore, it can be determined based on the indication information whether the PPDU uses a resource unit including contiguous subcarriers or a resource unit including discrete subcarriers.

[0258] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Although several embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments described herein. On the contrary, these embodiments are provided so that the present disclosure can be thoroughly and completely understood. It should be understood that the accompanying drawings and the embodiments of the present disclosure are merely used as examples and are not intended to limit the protection scope of the present disclosure.

[0259] The technical solutions in the embodiments of the present application may be applied to a wireless local area network (WLAN) system or to a communication system of another standard, such as a long-term evolution (LTE) system, a 5G system, or another future communication system. For example, in a WLAN system, a station (STA) and an access point (AP) are basic component devices of the WLAN system. An AP is an access point used by mobile users to access a wired network and is mainly deployed within homes, buildings, and campuses. A typical coverage radius ranges from tens of meters to hundreds of meters. Certainly, APs can also be deployed outdoors. An AP is equivalent to a bridge connecting a wired network and a wireless network. The main function of an AP is to connect wireless network clients together and then connect the wireless network to an Ethernet. Specifically, an AP may be a device having a Wi-Fi (Wireless Fidelity) chip, such as a terminal device or a network device having a Wi-Fi chip. Optionally, the AP may be a device supporting the 802.11ax standard. Optionally, the AP may alternatively be a device that supports multiple WLAN standards, such as 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a. Furthermore, the AP may alternatively be a device that supports the 802.11be WLAN standard and another future 802.11 standard. The types of standards supported by the AP are not limited in the embodiments of the present application.

[0260] A STA is generally a terminal device in a WLAN system. The STA may be mobile or fixed. The STA is the most basic component device of a wireless local area network. The STA may be a wireless communication chip, a wireless sensor, or a wireless communication terminal such as a mobile phone supporting Wi-Fi communication, a tablet computer supporting Wi-Fi communication, a set-top box supporting Wi-Fi communication, a smart television supporting Wi-Fi communication, a smart wearable device supporting Wi-Fi communication, an in-vehicle device supporting Wi-Fi communication, or a computer supporting Wi-Fi communication. Similarly, the STA may be a device supporting the 802.11ax standard, or a device supporting multiple WLAN standards, such as 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a. Alternatively, the STA may be a device supporting the 802.11be WLAN standard and another future 802.11 standard. In the embodiment of the present application, the types of standards supported by the STA are not limited.

[0261] As used herein, the term "include" and similar terms should be understood as an open inclusion, i.e., "include but not limited to." Unless otherwise specified, the term "or" means "and / or." The term "based on" means "at least partially based on." The terms "example embodiment" and "some embodiment" refer to "at least one example embodiment." Terms such as "first," "second," etc. may refer to different objects or the same object. Other explicit and implicit definitions may be further included below.

[0262] IEEE 802.11 is one of the mainstream wireless access standards and has been widely used in commercial applications for the past decade. Communication devices may transmit data over a specific bandwidth. Resources in the bandwidth may be allocated based on a pre-defined tone plan. For example, the 802.11be standard defines a contiguous resource unit (RU)-based tone plan. Figure 1A is a schematic diagram illustrating a contiguous RU-based tone plan for a 20 MHz bandwidth. As shown in Figure 1A, when the bandwidth is 20 MHz, the entire bandwidth may include one 242-tone RU or various combinations of smaller RUs, such as 26-tone RU, 52-tone RU, and 106-tone RU.

[0263] Figure 1B is a schematic diagram of a contiguous RU-based tone plan for a 40 MHz bandwidth. As shown in Figure 1B, when the bandwidth is 40 MHz, the entire bandwidth may include one 484-tone RU or various combinations of smaller RUs, such as 26-tone RUs, 52-tone RUs, 106-tone RUs, and 242-tone RUs. The 40 MHz bandwidth tone plan may be considered a duplicate of the 20 MHz bandwidth tone plan.

[0264] Figure 1C shows the 80MHz Bandwidth 1C is a schematic diagram showing a contiguous RU-based tone plan for 80 MHz WDM. As shown in FIG. 1C, when the bandwidth is 80 MHz, the entire bandwidth includes four RUs in units of 242-tone RUs. The entire bandwidth may include one 996-tone RU or various combinations of smaller RUs, such as 26-tone RUs, 52-tone RUs, 106-tone RUs, 242-tone RUs, and 484-tone RUs. In this specification, 484L and 484R represent the left and right half portions of a single 484-tone RU, respectively. Each portion includes 242 subcarriers.

[0265] Similar tone plans may be used for other bandwidth configurations. For example, if the bandwidth is 160 MHz or 80+80 MHz, the corresponding tone plan may be considered a duplicate of the tone plan for two 80 MHz bandwidths. Specifically, the entire bandwidth may include one 2×996-tone RU, or may include various combinations of smaller RUs, such as 26-tone RU, 52-tone RU, 106-tone RU, 242-tone RU, 484-tone RU, and 996-tone RU. If the bandwidth is 240 MHz or 160+80 MHz, the corresponding tone plan may be considered a duplicate of the tone plan for three 80 MHz bandwidths. Plan If the bandwidth is 320 MHz or 160+160 MHz, the corresponding tone plan can be considered as a duplicate of the tone plan for four 80 MHz bandwidths.

[0266] The tone plan described above is in units of 242-tone RUs. The left portion of the diagram corresponds to the lowest frequency, and the right portion corresponds to the highest frequency. From left to right, the 242-tone RUs are numbered as 1st RU, 2nd RU, 3rd RU, 4th RU, ..., and 16th RU. It should be noted that in the data field, there are up to 16 242-tone RUs, which correspond one-to-one to the 16 20 MHz channels in ascending frequency order.

[0267] In addition to the above-mentioned RUs, the following RUs are further introduced in the 802.11be standard: 52+26-tone RU formed by one conventional 52-tone RU and one conventional 26-tone RU, A 106+26-tone RU formed by one conventional 106-tone RU and one conventional 26-tone RU; A 484+242-tone RU formed by one conventional 484-tone RU and one conventional 242-tone RU; 996+484-tone RU formed by one conventional 996-tone RU and one conventional 484-tone RU; 2*996+484-tone RU formed by two conventional 996-tone RUs and one conventional 484-tone RU; 3*996-tone RU formed by three traditional 996-tone RUs, as well as 3*996+484-tone RU formed by three traditional 996-tone RUs and one traditional 484-tone RU.

[0268] In the above-described bandwidth configuration, a single RU includes contiguous subcarriers and is also referred to as a contiguous RU or nominal RU. In addition to the RU used for data transmission, a guard subcarrier, a null subcarrier, a direct current (DC) subcarrier, etc. are typically included. It should be understood that a resource unit is a relative concept, and the size of a resource unit depends on the number of subcarriers (tones) included. In terms of bandwidth, a 26-tone RU corresponds approximately to 2 MHz, a 52-tone RU corresponds approximately to 4 MHz, a 106-tone RU corresponds approximately to 8 MHz, and a 242-tone RU corresponds approximately to 20 MHz. Other RU sizes can be similarly obtained based on additive or multiplicative relationships. Details will not be described herein.

[0269] A conventional nominal RU includes data subcarriers and pilot subcarriers that are consecutively distributed in the frequency domain. The data subcarriers are used to carry data information from higher layers, and the pilot subcarriers transmit fixed values, allowing the receiving end device to perform phase estimation and phase correction. A nominal RU distributed over a 20 MHz bandwidth includes 256 subcarriers, with index values ​​ranging from [-128,...,0,...,127]. Table 1 shows the RU indexes and subcarrier ranges for various bandwidth configurations in 20 MHz. In this specification, RU# identifies the RU index, [a,b] represents the subcarrier range of the corresponding RU from index a to index b, including a and b, {x,y,...} represents the corresponding index representing the pilot subcarrier, and the number of elements in {} represents the number of pilot subcarriers.

[0270] [Table 1]

[0271] Similarly, Table 2 below shows the RU index and subcarrier range for various 40 MHz bandwidth configurations.

[0272] [Table 2]

[0273] It should be understood that in addition to contiguous RUs in the strict sense, 26-tone RUs containing two contiguous 13-tone tones, 484-tone RUs containing two contiguous 242 tones (484L and 484R), and 996-tone RUs containing two contiguous 498 tones (996L and 996R) may also be referred to as contiguous RUs in the broad sense. For the subcarrier range of an n x 996-tone RU, if the bandwidth is 80 MHz, the subcarrier range of the 996-tone RU is [-500:-3, 3:500]. If the bandwidth is larger, the subcarrier range of the n * 996-tone RU can be obtained by reusing the structure of the pilot subcarriers. For multiple RUs, the subcarrier range and pilot index of the multiple RUs are the collection of the subcarrier ranges and pilot indices of the RUs that form the multiple RUs.

[0274] When a communication device transmits data using WLAN technology, the communication device is limited by both the maximum transmission power and the maximum power spectral density. For example, the Federal Communications Commission of the United States recently issued relevant regulations on the 6 GHz spectrum, defining a communication method for indoor-only low-power (LPI). According to these regulations, the maximum power of an AP is limited to 36 dBm, and the maximum power spectral density is limited to 5 dBm / MHz. For a STA, the maximum power of the STA is limited to 24 dBm, and the maximum power spectral density is limited to -1 dBm / MHz. Compared to the maximum power, the maximum power spectral density is more restricted. The maximum allowed power is generally more affected than the power spectral density. As the transmission bandwidth increases, the maximum transmission power of the communication device increases accordingly. As shown in Table 3, when the bandwidth is 320 MHz, the transmission power reaches the maximum power specified in the above-mentioned regulations. When the bandwidth and RU are smaller, in a scenario where the power spectral density is limited, the communication device can usually transmit data only at a power much lower than the maximum power. This has a significant effect on the transmission speed and distance.

[0275] [Table 3]

[0276] To solve these problems, an improved solution is provided according to an example embodiment of the present disclosure. In this improved solution, a physical resource unit (PRU) formed by discrete subcarriers is used to transmit data over a larger bandwidth than a continuous RU. In this way, the transmitting end equipment can transmit data with a higher transmission power. Furthermore, the discrete subcarriers are evenly distributed across the entire bandwidth for each segment, ensuring that the discrete subcarriers of the VRU do not cause a large PAPR increase in data transmission. In the above-described subcarrier division solution, the LTF (long training field) field corresponding to each user can have a low PAPR. In the technical solution of the present disclosure, bandwidth resources can be fully utilized in this manner, thereby improving system efficiency.

[0277] Exemplary embodiments of the present disclosure are described in detail below with reference to FIGS.

[0278] FIG. 2 is a schematic diagram illustrating a communication environment 200 in which an embodiment of the present disclosure can be implemented. As shown in FIG. 2, the communication environment 200 includes an access point AP 210 and stations STAs 220-1 and 220-2 (sometimes collectively referred to as stations STA 220). The access point AP 210 accesses the Internet 230 via a wired or wireless manner. It should be understood that the communication environment 200 is used merely as an example and does not imply any limitation on the scope of the present application. Furthermore, embodiments of the present application may be embodied in other network environments or architectures. It should also be understood that the communication environment 200 may further include other components or entities for purposes such as communication connections, data transmission, and network security. For simplicity of explanation, these components or entities are not shown in FIG. 2, but this does not mean that embodiments of the present application do not include these elements or entities.

[0279] An access point (AP) may provide wireless network coverage to stations (STAs) within a specific area. For example, the access point (AP) 210 may be associated with stations (STAs) 220-1 and 220-2 and may perform uplink and downlink communications using a predetermined protocol (e.g., the IEEE 802.11 protocol) including point-to-multipoint and point-to-point transmissions. Packet data based on various frame structures, such as a physical layer protocol data unit (PPDU), may be transmitted between the access point (AP) 210 and the stations (STAs) 220.

[0280] The network environment 200 according to this embodiment of the present application may be a wireless network conforming to any currently known or future-developed protocol, including, but not limited to, standards-based WLANs such as 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a, Narrowband Internet of Things (NB-IoT) systems, Global System for Mobile Communications (GSM), Enhanced Data Rate GSM Evolution (EDGE) systems, Wideband Code Division Multiple Access (WCDMA) systems, Code Division Multiple Access 2000 (CDMA2000) systems, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, Long Term Evolution (LTE) systems, and 5G NR networks.

[0281] In some embodiments, the access point AP 210 may be, for example, a wireless router. The stations STA 220-1 and 220-2 may include wireless mobile devices. Examples of wireless mobile devices include, but are not limited to, smartphones, notebook computers, tablet computers, smart wearable devices, and in-vehicle mobile devices.

[0282] [First implementation of the present disclosure] According to the above description of the current bandwidth configuration and subcarrier resource division, for resource units RU of the same size, the relative positions of pilot subcarriers in the resource unit RU are not necessarily the same. If the nominal resource unit RU is directly and uniformly discretized on a larger bandwidth, some subcarriers may be mapped to the positions of the original pilot subcarriers, and some pilot subcarriers may be mapped to the positions of the original data subcarriers. Obviously, this does not promote communication quality and data transmission.

[0283] According to an example embodiment of the present disclosure, an improved communication mechanism is provided. In the improved communication mechanism, a PPDU is transmitted based on a specific tone plan by using a physical resource unit (PRU) including discrete subcarriers, and a mapping relationship exists between the PRU and the VRU. This mechanism may involve an access point 210 and a station STA 220 as shown in FIG. 2.

[0284] A schematic diagram of reconfiguring a physical resource unit PRU will be described below with reference to FIG.

[0285] As shown in Figure 3, an example in which the first bandwidth is 80 MHz is used. The first bandwidth may include virtual resource units VRUs, for example, four 242-tone VRUs 311-314. According to the tone plan, the pilot subcarriers of 242-tone VRUs 311 and 313 have the same location in each RU, and the pilot subcarriers of 242-tone VRUs 312 and 314 have the same location in each RU. In practice, the four 242-tone VRUs 311-314 are separately assigned to one or more users for simultaneous uplink orthogonal frequency division multiple access (OFDMA) transmissions.

[0286] In step 1, the subcarriers of some VRUs in the group of VRUs 311-314 are inverted in the frequency domain to obtain VRUs 311'-314'. For example, 242-tone RUs 311 and 313 may be inverted. Alternatively, in another example, 242-tone RUs 312 and 314 may be inverted. In the example of Figure 3, the subcarriers of 242-tone RUs 312 and 314 are inverted. After inversion, the pilot subcarriers of 242-tone VRUs 311'-314' have the same relative positions in each RU of the 242-tone VRUs 311'-314'.

[0287] In some example embodiments, after the inversion in step 1, inversion may be further performed for some consecutive subcarriers in VRUs 311'-314' in the frequency domain. For example, each of 242-tone VRUs 311'-314' includes two 106-tone VRUs, and the subcarriers of one 106-tone VRU in each of 242-tone VRUs 311'-314' are inverted, thereby more evenly distributing the pilot subcarriers in VRUs 311'-314'.

[0288] In step 2, the subcarriers in each of the 242-tone VRUs 311'-314' are indexed and divided into N RU segments, where N is the number of VRUs corresponding to the first bandwidth. In this specification, the first RU segment is {1, 5, 9,..., 241}, the second RU segment is {2, 6, 10,..., 242}, the third RU segment is {3, 7, 11,..., 239}, and the fourth RU segment is {4, 8, 12,..., 240}.

[0289] In step 3, N RU segments from different 242-tone VRUs 311'-314' form N reconstructed RUs. In other words, each reconstructed RU contains N segments from different VRUs 311'-314', and every Nth consecutive subcarrier corresponds to a different 242-tone VRU in the frequency domain 311'-314'. The reconstructed RUs formed based on step 3 have a structure similar to that of the data.

[0290] In embodiments where after step 1, inversion is performed for several consecutive subcarriers in VRU 311′-314′, inversion may be performed for the portion belonging to each reconstructed RU that corresponds to several consecutive subcarriers in VRU 311′-314′.

[0291] Step 4: Perform inversion on the reconstructed RUs corresponding to some inverted VRUs in VRUs 311 to 314 to obtain physical resource units PRUs 321 to 324. For example, if inversion is performed on the subcarriers of 242-tone VRUs 311 and 313 in step 1, then inversion is performed on the subcarriers of reconstructed RUs 321 and 323 in step 4. If inversion is performed on the subcarriers of 242-tone VRUs 312 and 314 in step 1, then inversion is performed on the subcarriers of reconstructed RUs 322 and 324 in step 4. In this way, the effect of the processing in step 1 on the original RU division can be restored.

[0292] The PRUs 321 to 324 obtained according to steps 1 to 4 are equally distributed separately in the first bandwidth of 80 MHz and occupy different subcarrier positions. Alternatively, the PRUs 321 to 324 are VRUs 3 1 1 to 3 1 4, each with the same subcarrier division as PRU3 1 1 to 3 1 Each of 4 and VRU3 1 1 to 3 1 There is a mapping relationship between each of the four.

[0293] Although the first implementation is described by using an example in which the first bandwidth is 80 MHz, this mechanism is also applicable to other bandwidths (e.g., 160 MHz or 320 MHz) and other sized VRUs. For example, if the first bandwidth is 160 MHz, the first bandwidth includes eight 242-tone VRUs. Correspondingly, in step 2, each VRU may be equally divided into eight RU segments, and then, in step 3, the eight reconstructed 242-tone RUs are formed in a manner similar to Sudoku. In another example, if the first bandwidth is 320 MHz, the first bandwidth includes 16 242-tone VRUs. Correspondingly, in step 2, each VRU may be equally divided into 16 RU segments, and then, in step 3, the 16 reconstructed 242-tone RUs are formed in a manner similar to Sudoku. (registered trademark) Furthermore, the 320 MHz bandwidth can be further divided into two 160 MHz bandwidths to perform similar operations, which will not be explained again here.

[0294] In some example embodiments, the size of a resource unit (RU) may differ from the size of a 242-tone RU. For example, a resource unit may be a 106-tone RU, a 484-tone RU, or a 996-tone RU. For example, if a group of 106-tone VRUs is discretized and reconstructed, operations may still be performed in units of 242 tones, and the user only uses the discretized results of the subcarriers corresponding to the 106-tone RU.

[0295] In some example embodiments, StepsWhen the operation of 3 is performed, multiple reconstruction solutions that fit the Sudoku structure can be obtained. A reconstruction solution that enables the LTF field corresponding to the user to have the smallest peak to average power ratio (PAPR) can be selected. Furthermore, the reconstruction solutions can be pre-configured on the transmitting end and the receiving end of the communication, and the PPDU is transmitted or received on the first bandwidth based on the reconstruction solution.

[0296] In some example embodiments, the PPDU may include indication information, or the transmitting end device may transmit indication information independently of the PPDU, to indicate whether the PRU used for the PPDU includes continuous or discrete subcarriers.

[0297] [Second implementation of the present disclosure] A second implementation of the present disclosure involves a process similar to the first implementation. A process 400 for generating PRUs containing discrete subcarriers is described below with reference to FIG.

[0298] As shown in FIG. 4, for a first bandwidth including N 242-tone VRUs, in block 401, the subcarriers of a first group of VRUs in the N 242-tone VRUs are reversed in the frequency domain to obtain modified VRUs. For example, the first group of VRUs may include VRUs in the N 242-tone VRUs whose RU indices are odd. Alternatively, in another example, the first group of VRUs may include VRUs in the N 242-tone VRUs whose RU indices are even. After the reversal and reordering are performed, the pilot subcarriers of the VRUs have the same relative positions in each RU.

[0299] Optionally, after block 401, at least some consecutive subcarriers in each VRU may be further inverted in the frequency domain. For example, the second 52-tone RU and the fourth 52-tone RU in each 242-tone VRU may be inverted. Alternatively, the first 52-tone RU and the third 52-tone RU may be inverted. In this way, the pilot subcarriers in each 242-tone VRU are more evenly distributed.

[0300] In block 402, the subcarriers in the N inverted VRUs are indexed, and each inverted VRU is divided into the following N RU segments: a first RU segment of {1, N+1, 2*N+1,...}, a second RU segment of {2, N+2, 2*N+2,...}, a third RU segment of {3, N+3, 2*N+3,...}, ..., and an Nth RU segment of {N, 2*N, 3*N,...}, where N is the number of VRUs corresponding to the first bandwidth.

[0301] In block 403, N RU segments from different VRUs are combined into a reconstructed RU to obtain a total of N reconstructed RUs. In other words, each reconstructed RU includes a first RU segment, a second RU segment, ..., and an Nth RU segment, each from a different VRU. Also, in the frequency domain, every Nth consecutive subcarrier corresponds to a different VRU. In other words, the reconstructed RU obtained in block 403 has a structure similar to that of data.

[0302] If after block 401, inversion is performed for at least some consecutive subcarriers in each VRU, after block 403, inversion is performed for the portion in each reconstructed RU that corresponds to at least some consecutive subcarriers in each changed VRU, so that the effect on RU division can be restored.

[0303] In block 404, inversion is performed on reconstructed RUs corresponding to inverted VRUs in the N modified VRUs to obtain N PRUs containing discrete subcarriers. For example, if inversion is performed on subcarriers of VRUs whose RU index is odd in block 401, inversion is performed on subcarriers of reconstructed RUs whose RU index is odd in block 404. If inversion is performed on subcarriers of VRUs whose RU index is even in block 401, inversion is performed on subcarriers of reconstructed RUs whose RU index is even in block 404. In this way, the effect of the change in block 401 on the original RU division can be restored.

[0304] According to the communication mechanism provided in this embodiment of the present disclosure, the continuous subcarriers of the VRU are evenly distributed across a larger bandwidth to form a PRU that includes discrete subcarriers occupying the entire bandwidth, allowing the transmitting end device to transmit data with high transmission power. The discretized subcarriers are evenly distributed across the bandwidth for each segment to ensure that the discretization of the VRU does not cause a large increase in PAPR during data transmission. Based on this mechanism, the technical solution of the present disclosure can fully utilize bandwidth resources, thereby improving system efficiency.

[0305] [Third implementation of the present disclosure] According to a third implementation of the present disclosure, an example of a process for discretizing subcarriers in units of 996-tone RUs on a first bandwidth is provided. The first bandwidth may be 160 MHz or 320 MHz and is assumed to include N 996-tone RUs. Each 996-tone RU may include four 242-tone RUs, such as a first 242-tone RU, a second 242-tone RU, a third 242-tone RU, and a fourth 242-tone RU.

[0306] When determining the PRU to be used to transmit the PPDU, the first group of 242-tone VRUs in the 996-tone VRU may be inverted. For example, the second and fourth 242-tone RUs in each 996-tone VRU, i.e., the 242-tone RUs with even indices, may be inverted. Alternatively, the first and third 242-tone RUs in each 996-tone VRU, i.e., the 242-tone RUs with odd indices, may be inverted. This is not a limitation of the present disclosure. In this way, the positions of the pilot subcarriers in each modified 996-tone VRU are more evenly distributed. It should be understood that the above-described steps are optional. In practice, this can be achieved even if the above-described steps are not performed.

[0307] The subcarrier index of each 996-tone RU is {1,...,996}, and the indexed subcarriers are divided into the following N RU segments: a first RU segment of {1,N+1,2*N+1,...}, a second RU segment of {2,N+2,2*N+2,...}, a third RU segment of {3,N+3,2*N+3,...}, ..., and an Nth RU segment of {N,2*N,3*N,...}. Here, N is equal to the number of VRUs corresponding to the first bandwidth.

[0308] Next, N RU segments from N different 996-tone VRUs are reconstructed into N 996-tone PRUs. The reconstructed 996-tone PRUs have a result similar to Sudoku. Specifically, each 996-tone PRU includes N RU segments, i.e., a first RU segment, a second RU segment, ..., and an Nth RU segment, and the N RU segments in the same reconstructed 996-tone PRU are from N different 996-tone VRUs. In terms of frequency, every N adjacent subcarriers on the first bandwidth are from N different 996-tone PRUs.

[0309] In some embodiments, if the optional step of inverting subcarriers is performed first when the PRUs are determined, the corresponding 242-tone PRUs in the reconstructed 996-tone PRU are inverted separately, thus eliminating the effect of the optional step described above on subcarrier division.

[0310] According to the communication mechanism provided in this embodiment of the present disclosure, the continuous subcarriers of the VRU are evenly distributed across a larger bandwidth to form a PRU that includes discrete subcarriers occupying the entire bandwidth. Furthermore, the original subcarrier resource division result remains unchanged. In this way, the transmitting end equipment can be allowed to transmit data at a high transmit power. The discretized subcarriers are evenly distributed across the bandwidth for each segment to ensure that the discretization of the VRU does not cause a large increase in PAPR during data transmission. Therefore, the technical solution of the present disclosure can fully utilize bandwidth resources, thereby improving system efficiency.

[0311] It should be understood that, based on the first to third implementations of the present disclosure, multiple subcarrier discretization solutions that fit the Sudoku structure can be obtained. In practice, a specific subcarrier discretization solution can be selected according to requirements and pre-configured at the transmitting end and the receiving end, and communication is performed based on the solution.

[0312] Tables 4 to 6 below provide RU indexes, subcarrier ranges, and pilot subcarrier indexes based on different tone plans and communication mechanisms provided in this disclosure. The reconfiguration solution may result in lower PAPR and better system performance. Certainly, other reconfiguration solutions are also feasible.

[0339] It should be understood that the specific tone plans shown in Tables 4 through 7 and the principles of the example embodiments of the present disclosure are also applicable to bandwidth configurations in which the total bandwidth or RU size is a different value. For example, if a PPDU is transmitted or received over a total bandwidth of 320 MHz, the total bandwidth may be divided into a first portion of bandwidth and a second portion of bandwidth, each portion being 160 MHz, and a tone plan based on Table 6 or Table 7 may be applied to each portion of bandwidth. In another example, the total bandwidth of 320 MHz may be divided into a first portion of bandwidth, a second portion of bandwidth, a third portion of bandwidth, and a fourth portion of bandwidth, each portion being 80 MHz, and a tone plan based on Table 4 or Table 5 may be applied to each portion of bandwidth. And so on. Therefore, details of bandwidth configurations and tone plans based on similar principles will not be described herein.

[0340] 5 is a flowchart illustrating a communication method according to one embodiment of the present disclosure. The method 500 may be implemented at the access point AP 210 or at the STA end shown in FIG. 2. For ease of explanation, the method 500 will be described below with reference to FIG. 2. It should be understood that the method 500 is also applicable to other communication scenarios and communication devices.

[0341] The following describes the method 500 by using the AP 210 as an example. It should be understood that the STA end may also perform the method 500. For example, both the STA 220-1 and the STA 220-2 may perform the method 500.
