[0002] The present application relates to the field of communication technology, and in particular to a communication method and apparatus. BACKGROUND

[0003] With the continuous evolution of communication technology, using wireless networks for data services has become one of the important ways of data transmission. In wireless networks, the frequency band applied by wireless local area networks (WLAN) has been expanded from licensed frequency bands to unlicensed frequency bands. The licensed frequency band refers to a frequency spectrum range that requires a specific spectrum license to use, and the unlicensed frequency band refers to a frequency spectrum range that can be used without a specific spectrum license. How to apply licensed frequency bands and unlicensed frequency bands for data transmission remains to be studied. SUMMARY

[0004] Embodiments of the present application provide a communication method and apparatus, which can realize 100MHz data transmission and improve spectrum utilization.

[0005] In a first aspect, embodiments of the present application provide a communication method, which can be executed by a first device. The first device can refer to the first device itself, or a processor, module, chip, or chip system in the first device that implements the method. In the method, the first device generates a first physical layer protocol data unit (PPDU), and the first PPDU includes bandwidth field indication information. The bandwidth field indication information is used to indicate that the bandwidth of the first PPDU is 100MHz. The first device transmits the first PPDU using a 100MHz channel.

[0006] As can be seen, in embodiments of the present application, the first device transmits the first PPDU with a bandwidth of 100MHz using a 100MHz channel, and 100MHz data transmission can be realized. Compared with the first device transmitting information using a PPDU defined by a protocol, the spectrum utilization can be improved.

[0007] In a possible implementation, the bandwidth field indication information is a bandwidth field. In a possible implementation, the first PPDU includes a general signaling field, and the general signaling field includes the bandwidth field. The bandwidth field is used to indicate that the bandwidth of the first PPDU is 100MHz.

[0008] In an alternative embodiment, 80MHz of the 100MHz corresponds to a 996-tone resource unit (RU) and 20MHz corresponds to a 242-tone RU, such that the 100MHz channel can include a 996+242-tone multi-resource unit (MRU), e.g., the 100MHz channel transmitting the first PPDU includes a 996+242-tone MRU.

[0009] As can be seen, when there is no puncturing in the 100MHz, the 100MHz channel transmitting the first PPDU can include a 996+242-tone MRU.

[0010] In another alternative embodiment, 40MHz of the 100MHz corresponds to a 484-tone RU and the remaining three 20MHz each correspond to a 242-tone RU, such that the 100MHz channel can include a 484-tone RU and three 242-tone RUs, e.g., the 100MHz channel transmitting the first PPDU includes a 484-tone RU and three 242-tone RUs.

[0011] In yet another alternative embodiment, five 20MHz of the 100MHz each correspond to a 242-tone RU, such that the 100MHz channel can include five 242-tone RUs, e.g., the 100MHz channel transmitting the first PPDU includes five 242-tone RUs.

[0012] In yet another alternative embodiment, two 40MHz of the 100MHz each correspond to a 484-tone RU and the other 20MHz corresponds to a 242-tone RU, such that the 100MHz channel can include a 242-tone RU and two 484-tone RUs, e.g., the 100MHz channel transmitting the first PPDU includes a 242-tone RU and two 484-tone RUs.

[0013] In yet another alternative embodiment, 80MHz of the 100MHz corresponds to a 996-tone RU and 20MHz corresponds to a 242-tone RU, such that the 100MHz channel can include a 242-tone RU and a 996-tone RU, e.g., the 100MHz channel transmitting the first PPDU includes a 242-tone RU and a 996-tone RU.

[0014] In another alternative implementation, 60MHz of the 100MHz corresponds to a 484+242-tone MRU and the other 40MHz corresponds to a 484-tone RU, so that the 100MHz channel can include a 484+242-tone MRU and a 484-tone RU, such as the 100MHz channel transmitting the first PPDU includes a 484+242-tone MRU and a 484-tone RU.

[0015] In another alternative implementation, 60MHz of the 100MHz corresponds to a 484+242-tone MRU and the other two 20MHz each corresponds to a 242-tone RU, so that the 100MHz channel can include a 484+242-tone MRU and two 242-tone RUs, such as the 100MHz channel transmitting the first PPDU includes a 484+242-tone MRU and two 242-tone RUs.

[0016] It can be seen that when there is no punching in the 100MHz, the 100MHz channel transmitting the first PPDU includes RUs / MRUs which can be obtained by combining one or more RUs / MRUs defined by the protocol, which can reduce the complexity of implementation.

[0017] In an alternative implementation, there is 20MHz punched in the 100MHz. In this way, the first PPDU further includes punching field indication information, and the punching field indication information is used to indicate that 20MHz in the 100MHz is punched, and the 20MHz is located in the lowest 80MHz in the 100MHz, or in other words, the 20MHz is not the highest 20MHz in the 100MHz.

[0018] In a possible implementation, the punching field indication information is a punching field. In a possible implementation, the first PPDU includes a general signaling field, and the general signaling field includes the punching field, and the punching field is used to indicate that 20MHz in the 100MHz is punched, and the 20MHz is located in the lowest 80MHz in the 100MHz.

[0019] In an alternative implementation, when 20MHz in the 100MHz is punched, 40MHz in the 100MHz which is not punched can correspond to a 484-tone MRU, and the other two 200MHz which is not punched can each correspond to a 242-tone RU, so that the 100MHz channel can include a 484+242+242-tone MRU, such as the 100MHz channel transmitting the first PPDU includes a 484+242+242-tone MRU.

[0020] In another alternative implementation, when 20MHz of the 100MHz is punctured, the two 40MHz of the 100MHz that are not punctured can each correspond to a 484-tone MRU, and the two 40MHz that are not punctured can be contiguous or non-contiguous, so that the 100MHz channel can include a 484+484-tone MRU, such as the 100MHz channel that transmits the first PPDU includes a 484+484-tone MRU, and the two 484 subcarriers of the 484+484-tone MRU are contiguous or non-contiguous.

[0021] In yet another alternative implementation, when 20MHz of the 100MHz is punctured, the 80MHz of the 100MHz that is not punctured can correspond to a 996-tone RU, and the 80MHz that is not punctured can be contiguous or non-contiguous, so that the 100MHz channel can include a 996-tone RU, such as the 100MHz channel that transmits the first PPDU includes a 996-tone RU, and the 996 subcarriers of the 996-tone RU are contiguous or non-contiguous.

[0022] It can be seen that when 20MHz of the 100MHz is punctured, the 100MHz channel that transmits the first PPDU includes a 484+242+242-tone MRU, or the 100MHz channel that transmits the first PPDU includes a 484+484-tone MRU, or the 100MHz channel that transmits the first PPDU includes a 996-tone RU.

[0023] In another alternative implementation, there is 40MHz of the 100MHz that is punctured. In this implementation, the first PPDU further includes puncture field indication information, and the puncture field indication information is used to indicate that 40MHz of the 100MHz is punctured, and the 40MHz is located within the lowest 80MHz of the 100MHz, or in other words, the 40MHz does not include the highest 20MHz of the 100MHz.

[0024] In one possible implementation, the puncture field indication information is a puncture field. In one possible implementation, the first PPDU includes a general signaling field, and the general signaling field includes the puncture field, and the puncture field is used to indicate that 40MHz of the 100MHz is punctured, and the 40MHz is located within the lowest 80MHz of the 100MHz.

[0025] In an alternative embodiment, when 40MHz of the 100MHz is punctured, the 60MHz of the 100MHz which is not punctured can correspond to a 484+242-tone MRU, so that the 100MHz channel can include a 484+242-tone MRU, such as the 100MHz channel transmitting the first PPDU can include a 484+242-tone MRU.

[0026] In another alternative embodiment, when 40MHz of the 100MHz is punctured, each 20MHz of the 100MHz which is not punctured can correspond to a 242-tone MRU, so that the 100MHz channel can include a 242+242+242-tone MRU, such as the 100MHz channel transmitting the first PPDU can include a 242+242+242-tone MRU.

[0027] It can be seen that when 40MHz of the 100MHz is punctured, the 100MHz channel transmitting the first PPDU can include a 484+242-tone MRU, or the 100MHz channel transmitting the first PPDU can include a 242+242+242-tone MRU.

[0028] In an alternative embodiment, the transmission mode of the first PPDU is non-orthogonal frequency division multiple access transmission.

[0029] In another alternative embodiment, the transmission mode of the first PPDU is orthogonal frequency division multiple access transmission.

[0030] In an alternative embodiment, the transmission mode of the first PPDU is orthogonal frequency division multiple access transmission, and when the first PPDU further includes the puncturing field indication information, whether the puncturing field indication information indicates that 20MHz of the 100MHz is punctured or indicates that 40MHz of the 100MHz is punctured, the lowest 80MHz of the 100MHz corresponds to a 4-bit puncturing indication, the highest 20MHz of the 100MHz corresponds to a 4-bit puncturing indication, and the 4-bit of the highest 20MHz corresponds to 1111. Among them, the 4-bit of the lowest 80MHz of the 100MHz is used to indicate that 20MHz or 40MHz of the lowest 80MHz is punctured, and the 4-bit of the highest 20MHz is used to indicate that the highest 20MHz is not punctured.

[0031] In an alternative implementation, the transmission mode of the first PPDU is OFDMA transmission, and when the 100MHz channel transmitting the first PPDU is punctured, the 100MHz channel transmitting the first PPDU includes a first content channel and a second content channel in the low 80MHz, and a third content channel in the high 20MHz. The first content channel and the third content channel each carry three resource unit allocation fields, and the second content channel carries two resource unit allocation fields. The resource unit allocation fields carried by the first content channel, the second content channel and the third content channel are used to indicate the allocation of RUs or MRUs.

That is, the common fields of the first content channel, the common fields of the second content channel and the common fields of the third content channel can be located in one common encoding block respectively, which can save overhead. In this mode, the first common encoding block and the third common encoding block each carry three resource unit allocation fields, and the second common encoding block carries two resource unit allocation fields.

That is, the common fields of the first content channel and the common fields of the third content channel can be located in two common encoding blocks respectively, and the common fields of the second content channel can be located in one common encoding block. In this mode, the first common encoding block, the third common encoding block and the fourth common encoding block each carry two resource unit allocation fields, and the second common encoding block and the fifth common encoding block each carry one resource unit allocation field.

[0034] In another alternative implementation, the transmission mode of the first PPDU is OFDMA transmission, and when the 100MHz channel transmitting the first PPDU is punctured, the 100MHz channel transmitting the first PPDU includes a first content channel and a second content channel in the low 80MHz, and a third content channel in the high 20MHz. The first content channel, the second content channel and the third content channel each carry three resource unit allocation fields. The three resource unit allocation fields carried by the first content channel and the third content channel are used to indicate the allocation of RUs or MRUs. Among the three resource unit allocation fields carried by the second content channel, two resource unit allocation fields are used to indicate the allocation of RUs or MRUs, and one resource unit allocation field is a reserved field or is used to indicate puncturing information or is used to indicate reserved information.

[0035] In a possible implementation, the common field of the first content channel is located in a first common coding block, the common field of the second content channel is located in a second common coding block, and the common field of the third content channel is located in a third common coding block. That is, the common field of the first content channel, the common field of the second content channel, and the common field of the third content channel can be located in one common coding block respectively, and overhead can be saved. In this mode, the first common coding block, the second common coding block, and the third common coding block respectively carry three resource unit allocation fields.

That is, the common field of the first content channel, the common field of the second content channel, and the common field of the third content channel are located in two common coding blocks respectively. In this mode, the first common coding block, the third common coding block, and the fifth common coding block respectively carry two resource unit allocation fields, and the second common coding block, the fourth common coding block, and the sixth common coding block respectively carry one resource unit allocation field. Alternatively, the first common coding block, the third common coding block, and the fifth common coding block respectively carry two resource unit allocation fields, and the second common coding block, the fourth common coding block, and the sixth common coding block respectively carry one reserved field.

[0037] In an optional implementation, the 100 MHz belongs to 5735-5835 MHz in the unlicensed frequency band, for example, the 100 MHz for transmitting the first PPDU belongs to 5735-5835 MHz in the unlicensed frequency band. This mode can make 5735-5835 MHz in the unlicensed frequency band be fully utilized, and can improve the spectrum efficiency.

[0038] In a possible implementation, the 100 MHz belongs to the licensed frequency band, for example, the 100 MHz for transmitting the first PPDU belongs to the licensed frequency band. For example, in a specific environment, there is a 100 MHz bandwidth that is relatively available in the licensed frequency band, and then the first device can fully utilize the 100 MHz bandwidth to transmit information, and improve the spectrum utilization.

[0039] In a second aspect, the embodiments of the present application further provide a communication method, which can be executed by a first device. The first device can refer to the first device itself, or a processor, a module, a chip or a chip system, etc. in the first device implementing the method. In the method, the first device generates a first physical layer protocol data unit (PPDU). The first PPDU includes bandwidth field indication information and puncturing field indication information. The bandwidth field indication information is used to indicate that the bandwidth of the first PPDU is 160 MHz. The puncturing field indication information is used to indicate that the highest 60 MHz in the 160 MHz is punctured. The first device transmits the first PPDU by using a 100 MHz channel remaining after puncturing the highest 60 MHz in the 160 MHz.

[0040] It can be seen that, in the embodiments of the present application, the bandwidth field in the first PPDU generated by the first device indicates that the bandwidth of the first PPDU is 160 MHz, and the puncturing field indicates that the highest 60 MHz in the 160 MHz is punctured. Therefore, the actual bandwidth occupied by the first PPDU is 100 MHz, and the first device transmits the first PPDU by using a 100 MHz channel remaining after puncturing the highest 60 MHz in the 160 MHz, so that 100 MHz data transmission can be realized. Compared with the first device transmitting information by using a PPDU defined in a protocol, the frequency spectrum utilization can be improved.

[0041] In a possible implementation, the bandwidth field indication information is a bandwidth field. In a possible implementation, the first PPDU includes a general signaling field, and the general signaling field includes the bandwidth field.

In a possible implementation, the first PPDU includes a general signaling field, and the general signaling field includes the puncturing field. The puncturing field is used to indicate that the highest 60 MHz in the 160 MHz is punctured.

[0043] In an optional implementation, 80 MHz in the 100 MHz can correspond to a 996-tone resource unit (RU), and 20 MHz can correspond to a 242-tone RU, so that the 100 MHz channel can include a 996+242-tone multi-resource unit (MRU), such as the 100 MHz channel transmitting the first PPDU including a 996+242-tone MRU.

[0044] It can be seen that, when there is no puncturing in the 100 MHz, the 100 MHz channel transmitting the first PPDU can include a 996+242-tone MRU.

[0045] In another alternative implementation, 40 MHz of the 100 MHz can correspond to a 484-tone RU and the remaining three 20 MHz can each correspond to a 242-tone RU, such that the 100 MHz channel can include a 484-tone RU and three 242-tone RUs, e.g., the 100 MHz channel transmitting the first PPDU includes a 484-tone RU and three 242-tone RUs.

[0046] In yet another alternative implementation, the five 20 MHz of the 100 MHz can each correspond to a 242-tone RU, such that the 100 MHz channel can include five 242-tone RUs, e.g., the 100 MHz channel transmitting the first PPDU includes five 242-tone RUs.

[0049] In yet another alternative implementation, 60 MHz of the 100 MHz can correspond to a 484+242-tone MRU and the 40 MHz can correspond to a 484-tone RU, such that the 100 MHz channel can include a 484+242-tone MRU and a 484-tone RU, e.g., the 100 MHz channel transmitting the first PPDU includes a 484+242-tone MRU and a 484-tone RU.

[0050] In another alternative implementation, 60MHz in 100MHz can correspond to a 484+242-tone MRU, and the remaining two 20MHz can correspond to two 242-tone RUs respectively, so that the 100MHz channel can include a 484+242-tone MRU and two 242-tone RUs, such as the 100MHz channel transmitting the first PPDU includes a 484+242-tone MRU and two 242-tone RUs.

[0051] It can be seen that when there is no 20MHz being punctured in 100MHz, the RUs / MRUs included in the 100MHz channel transmitting the first PPDU can be obtained by combining one or more RUs / MRUs defined by the protocol, which can reduce the complexity of implementation.

[0052] In an alternative implementation, there is 20MHz being punctured in 100MHz. In this way, the puncturing field indication information is also used to indicate that 20MHz in 100MHz is punctured, and the 20MHz is located in the lowest 80MHz in 100MHz, or in other words, the 20MHz is not the highest 20MHz in 100MHz.

[0056] As can be seen, when 20MHz of the 100MHz is punctured, the 100MHz channel that transmits the first PPDU can include a 484+242+242-tone MRU, or the 100MHz channel that transmits the first PPDU can include a 484+484-tone MRU, or the 100MHz channel that transmits the first PPDU can include a 996-tone RU.

[0057] In another alternative implementation, there is 40MHz of the 100MHz that is punctured. In this implementation, the puncturing field indication information is further used to indicate that 40MHz of the 100MHz is punctured, and the 40MHz is located in the lowest 80MHz of the 100MHz, or in other words, the 40MHz does not include the highest 20MHz of the 100MHz.

Wherein, the first content channel, the second content channel and the third content channel respectively carry four resource unit allocation fields. In the four resource unit allocation fields respectively carried by the first content channel and the third content channel, three resource unit allocation fields are used to indicate the allocation of RUs or MRUs, and one resource unit allocation field is a reserved field or is used to indicate puncturing information or is used to indicate reserved information. In the four resource unit allocation fields carried by the second content channel, two resource unit allocation fields are used to indicate the allocation of RUs or MRUs, and two resource unit allocation fields are reserved fields or are used to indicate puncturing information or are used to indicate reserved information.

[0243] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

[0244] In order to better understand the embodiments of the present application, first, the system architecture related to the embodiments of the present application will be introduced as follows.

[0245] Please refer to FIG. 1, which is a schematic diagram of a system architecture provided by the embodiments of the present application. The system architecture can include one or more access points (APs) and one or more stations (STAs). The number and form of devices shown in FIG. 1 are used for example, and do not constitute a limitation on the embodiments of the present application. The system architecture shown in FIG. 1 is described taking AP1, AP2, STA1, STA2, STA3, and AP1 and AP2 being able to provide wireless services for STA1, STA2 and STA3 as an example. Among them, AP1 and AP2 in FIG. 1 take a base station as an example, and STA1, STA2 and STA3 take a mobile phone as an example.

[0246] The present application is applicable to data communication between one or more APs and one or more STAs, and is also applicable to communication between APs and APs, and communication between STAs and STAs.

[0247] The communication system to which embodiments of the application are applicable is a wireless local area network (WLAN) or a cellular network, or other wireless communication system that supports multiple links in parallel. Embodiments of the application are described mainly in the context of a network deployed according to IEEE 802.11, but aspects of the application can be extended to other networks using various standards or protocols, for example, Bluetooth, high performance radio LAN (HIPERLAN) (a wireless standard similar to IEEE 802.11, mainly used in Europe), and wide area network (WAN), personal area network (PAN) or other networks now known or later developed. Thus, the various aspects of the application can be applicable to any suitable wireless network, regardless of the coverage range and wireless access protocol used.

[0248] In embodiments of the application, a STA has a wireless transceiver function, and can support 802.11 series protocols, and communicate with an AP or other STAs. For example, a STA can be any user communication device that allows a user to communicate with an AP and thus with a WLAN, such as a tablet, desktop, laptop, notebook, ultra-mobile personal computer (UMPC), handheld computer, netbook, personal digital assistant (PDA), mobile phone, and the like, which can be networked, or an Internet of Things node in an Internet of Things, or a vehicle communication device in a vehicle Internet of Things, and the like. In one possible implementation, a STA can also be a chip and processing system in the above terminals.

[0249] In embodiments of the application, an AP is a device that provides services for STAs, and can support 802.11 series protocols. For example, an AP can be a communication server, a router, a switch, a bridge, and the like, or an AP can include various forms of macro base stations, micro base stations, relay stations, and the like, and of course an AP can also be a chip and processing system in the above various forms of devices, so as to implement the methods and functions of embodiments of the application.

[0250] In order to facilitate understanding of the embodiments disclosed in the application, the following two points are explained.

[0251] (1) The scenarios in the embodiments disclosed in the present application are described by taking the scenarios of a wireless fidelity (Wi-Fi) network in a wireless communication network as an example. It should be noted that the solutions in the embodiments disclosed in the present application can also be applied to other wireless communication networks, and the corresponding names can also be replaced by the names of corresponding functions in other wireless communication networks.

[0252] (2) The embodiments disclosed in the present application will present various aspects, embodiments or features of the present application around a system including a plurality of devices, components, modules, etc. It should be understood and appreciated that each system can include additional devices, components, modules, etc., and / or can not include all the devices, components, modules, etc. discussed in connection with the accompanying drawings. In addition, combinations of these solutions can also be used.

[0253] The following describes related concepts related to the embodiments of the present application:

[0254] 1. Physical layer protocol data unit (PPDU).

[0255] The PPDU can also be referred to as a physical layer data packet or a data packet. In the data field of the PPDU, a media protocol data unit (MPDU) is carried, that is, a medium access control layer protocol data unit (MAC PDU), that is, a commonly called medium access control (MAC) frame, such as a data frame, an acknowledgement frame, a trigger frame, a beacon frame, etc.

[0256] 2. Extreme high throughput multiple user physical layer protocol data unit (EHT MU PPDU).

[0257] The EHT MU PPDU is a PPDU defined in 802.11be, where EHT is the standard name of 802.11be, and MU represents multiple users, but can support single-user and multi-user data transmission.

[0258] Referring to FIG. 2, which is a schematic diagram of a frame structure of an EHT MU PPDU. The EHT MU PPDU includes a preamble part, a data field, and a packet extension (PE). The preamble part includes a legacy preamble, including a legacy short training field (L-SFT), a legacy long training field (L-LTF), and a legacy signal field (L-SIG), which is used to ensure the coexistence of new devices and legacy devices, wherein the L-SIG includes a length field, which can indirectly indicate the length of the part after the L-SIG in the EHT MU PPDU. The legacy preamble also includes a repeated L-SIG (RL-SIG), which is used to enhance the reliability of the L-SIG, and also provides a method for the receiving end to identify the data packet as an EHT PPDU through automatic detection by detecting whether the two symbols are the same, the remainder of the length in the L-SIG, and other features. In addition, the preamble part also includes a universal signal field (U-SIG), which exists in the PPDUs in the 802.11be standard and several generations of standards thereafter. The U-SIG is used to indicate that the PPDU is an EHT PPDU and a PPDU of a later generation of standards. If the PPDU is an EHT MU PPDU, there is also an EHT-SIG after the U-SIG. Both the U-SIG and the EHT-SIG carry signaling information needed to demodulate the subsequent data field. The preamble part also includes an extreme high throughput short training field (EHT-STF) and an extreme high throughput long training field (EHT-LTF), which are used for automatic gain control and channel estimation, respectively. The packet extension provides more time for the receiving end to process data.

[0259] The U-SIG field of the EHT MU PPDU includes a bandwidth field, the content of which can be seen in Table 1 below:

[0260] Table 1

[0261] As can be seen from Table 1, the first symbol of the two symbols of the U-SIG field is the symbol corresponding to the bandwidth field, which is used to indicate the bandwidth of the EHT MU PPDU, and when the B3-B5 bits in the symbol are set to 0-5 respectively, it indicates that the bandwidth of the EHT MU PPDU is 20MHz, 40MHz, 80MHz, 160MHz, 320-1MHz, and 320-2MHz respectively.

[0262] In addition, the reserved bits in the signaling field in the 802.11be physical layer preamble or the reserved state (entry) of a certain (sub) field in the signaling field is divided into two, namely Disregard and Validate, which can also be called ignore, verify, etc. For example, when the bandwidth field in Table 1 is set to 6 or 7, it is Validate, indicating a reserved state.

[0263] The channel transmitting the EHT MU PPDU supports puncturing operation, and the punctured channel information field is also located in the U-SIG field. The punctured channel information field is used to indicate the puncturing of each 20MHz subchannel in the channel transmitting the PPDU. The punctured channel information field can also be referred to as a preamble puncturing indication, or a puncturing field. The content of the punctured channel information field of the EHT MU PPDU can be seen from Table 2 as follows:

[0264] Table 2

[0265] As can be seen from Table 2, Table 3 is the content of the punctured channel information field of the U-SIG field in the EHT MU PPDU when non-OFDMA transmission is used. When OFDM transmission is used, a 4-bit is used to indicate the puncturing mode of the channel transmitting the EHT MU PPDU per 80MHz.

[0266] Table 3

[0267] In Table 3, for a certain bandwidth, the value of the bandwidth field is set to the rightmost column of Table 3, and its meaning is the middle two columns in Table 3. As can be seen from Table 3, for a certain bandwidth, when the bandwidth field is set to different values, it indicates different puncturing modes for the bandwidth. For example, when the bandwidth of the PPDU is 80MHz, and the value of the bandwidth field is set to 2, it indicates that according to the order of low frequency to high frequency in the 80MHz, the second 20MHz channel is punctured. When the bandwidth of the PPDU is 80MHz, and the value of the bandwidth field is set to 3, it indicates that according to the order of low frequency to high frequency in the 80MHz, the third 20MHz channel is punctured.

[0268] WLAN started from 802.11a / b / g, went through 802.11n, 802.11ac (Wi-Fi 5), 802.11ax (Wi-Fi 6), 802.11be (Wi-Fi 7), and is discussing 802.11bn (Wi-Fi 8). Before 802.11n, the standard defined a 20MHz bandwidth, and 802.11ac and 802.11ax further expanded to 40MHz, 80MHz, 160MHz, and 80MHz+80MHz. In 802.11be, 80MHz+80MHz is removed, and 320MHz is further defined, specifically two 320MHz bandwidth categories, 320MHz-1 and 320MHz-2.

[0269] Please refer to FIG. 3, which is a schematic diagram of channel division. As shown in FIG. 3, the channels in the 6GHz frequency band can be divided into subchannels with bandwidths of 80MHz, 160MHz, and 320MHz, wherein the 320MHz subchannels include 320MHz-1 subchannels with center frequencies of 31, 95, and 159 and 320MHz-2 subchannels with center frequencies of 63, 127, and 191.

[0270] In the formula, UNII represents the Unlicensed National Information Infrastructure (U-NII) radio band. In addition, the 80MHz in FIG. 3 can be further composed of 4 20MHz, wherein the 1st and 2nd 20MHz or the 3rd and 4th 20MHz can form a 40MHz.

[0271] In addition, the unlicensed spectrum is relatively limited, for example, in some countries and regions, there are 2.4GHz and 5GHz two frequency bands, but there is no 6GHz spectrum. FIG. 4 is another schematic diagram of channel division. Specifically, FIG. 4 is a schematic diagram of channel division for the 5GHz spectrum. The low-frequency part of the 5GHz (including UNII-1 and UNII-2A) is usually called 5.1GHz, which contains a maximum of 160MHz channels, and the standard defines a 160MHz bandwidth spectrum resource. In the high-frequency part of the 5GHz, usually called 5.8GHz, in some countries and regions, there are 100MHz (5735MHz-5835MHz) spectrum resources, while the standard defines a maximum of 80MHz and below bandwidth PPDU, so that the spectrum of 5.8GHz cannot be fully utilized.

[0272] In embodiments of the present application, the first device can be an AP, and the second device can be a STA. In a possible implementation, the first device can be a STA, and the second device can be an AP. In a possible implementation, the first device and the second device can be different APs. In a possible implementation, the first device and the second device can be different STAs.

[0273] Embodiments of the present application provide a communication method 100. FIG. 5 is an interaction diagram of the communication method 100. The communication method 100 is described from the perspective of the interaction between the first device and the second device. The communication method 100 includes but is not limited to the following steps:

[0274] S101. The first device generates a first PPDU, and the first PPDU includes bandwidth field indication information, which is used to indicate that the bandwidth of the first PPDU is 100 MHz.

[0275] The bandwidth of the first PPDU is 100 MHz, which can be that the first PPDU occupies a bandwidth of 100 MHz, or that a channel for transmitting the first PPDU is 100 MHz.

[0276] In a possible implementation, the first PPDU includes general signaling field indication information, and the general signaling field indication information includes the bandwidth field indication information. In a possible implementation, the general signaling field indication information can be a general signaling field, and the bandwidth field indication information can be a bandwidth field. That is, the first PPDU can include a U-SIG, and the U-SIG can include a bandwidth field, which is used to indicate that the bandwidth of the first PPDU is 100 MHz.

[0277] In an optional implementation, the first PPDU includes a U-SIG, and the U-SIG includes a bandwidth field. The value of the bandwidth field is set to 6 or 7. For example, Table 4 below shows the meaning of the bandwidth field when the value of the bandwidth field is set to different values. For example, as shown in Table 4, when the value of the bandwidth field of the first PPDU is set to 6, it indicates that the bandwidth of the first PPDU is 100 MHz; when the value of the bandwidth field of the first PPDU is set to 7, it is a validation field, indicating a reserved / unused state. For another example, when the value of the bandwidth field in Table 4 is set to 7, it indicates that the bandwidth of the first PPDU is 100 MHz; when the value of the bandwidth field in Table 4 is set to 6, it is a validation field, indicating a reserved / unused state.

[0278] It can be seen that when the first PPDU includes a U-SIG, the first device can directly use the bandwidth field defined in the U-SIG to indicate that the bandwidth of the first PPDU is 100 MHz, thereby reducing the indication overhead and complexity.

[0279] Table 4

[0280] In another alternative implementation, the bandwidth field indicates information is an extended bandwidth field, the extended bandwidth field is obtained by extending the existing bandwidth field in the U-SIG and part or all of the confirm bit and the ignore bit in the U-SIG, and the extended bandwidth field has a value greater than or equal to 8. For example, the first device extends the existing bandwidth field in the U-SIG and part of the confirm bit and the ignore bit in the U-SIG to obtain an extended bandwidth field of 4 bits, so that the extended bandwidth field can indicate a value of 0 to 15, and then the first device can indicate that the bandwidth of the first PPDU is 100 MHz by using any one of 6 to 15.

[0281] It can be seen that the first device can also indicate that the bandwidth of the first PPDU is 100 MHz based on the existing bandwidth field in the U-SIG and the confirm bit and the ignore bit, and this method can make the bandwidth indication of the first PPDU more flexible.

[0282] In an optional implementation, the first PPDU is an ultra high reliability physical layer protocol data unit (UHR PPDU), and the UHR PPDU is a PPDU in 802.11bn, that is, a PPDU in the Wi-Fi 8 standard. Please refer to FIG. 6, which is a schematic diagram of a frame structure of a UHR PPDU. As shown in FIG. 6, the UHR PPDU includes an L-STF field, used for discovery of the PPDU, coarse synchronization, and automatic gain control; an L-LTF field, used for fine synchronization and channel estimation; an L-SIG field and an RL-SIG field, used for carrying signaling information related to a length of the PPDU, ensuring coexistence, and repetition of the L-SIG and the RL-SIG is also used for automatic detection at a receiving end; a U-SIG field, used for carrying signaling for demodulation of subsequent data; a vendor specific SIG (VS-SIG) field, used for carrying vendor specific signaling information, and the field can be absent; an ultra high reliability signal field (UHR-SIG), used for carrying signaling for demodulation of subsequent data, and the field can be absent, for example, in a UHR TB PPDU; an ultra high reliability short training field (UHR-STF), used for automatic gain control; an ultra high reliability long training field (UHR-LTF), used for channel estimation; a data field, used for carrying data information; and a PE, used for increasing processing time of a receiver.

[0283] In a possible implementation, the frame structure of the UHR PPDU can also be different from the frame structure shown in FIG. 6, and embodiments of the present application do not limit the frame structure of the UHR PPDU.

[0284] In a possible implementation, the first PPDU can be a PPDU in a standard later than 802.11bn, and embodiments of the present application do not limit this. For ease of description, the first PPDU is taken as an example of a UHR PPDU in the following description.

[0285] In addition, the transmission mode of the first PPDU includes non-OFDMA transmission and OFDMA transmission. In the following, implementation of a 100 MHz channel is described with respect to the two transmission modes of non-OFDMA transmission and OFDMA transmission.

[0286] Transmission mode 1.1: non-OFDMA transmission.

[0287] In non-OFDMA transmission, all frequency domain resources in the 100MHz bandwidth are allocated to one user or a group of users as a whole for transmission, which can be further divided into single-user transmission or multi-user multiple-input multiple-output (MU-MIMO) transmission.

[0288] For the first PPDU of 100MHz, when non-OFDMA transmission is used, the MRU in the 100MHz channel needs to be redefined. In addition, the 100MHz channel can be non-punctured or punctured. When the 100MHz channel is punctured, 20MHz in the 100MHz channel can be punctured, or 40MHz in the 100MHz channel can be punctured. Therefore, the following describes the implementation of the 100MHz channel in non-OFDMA transmission for the following three scenarios: no puncturing in the 100MHz channel, 20MHz in the 100MHz channel being punctured, and 40MHz in the 100MHz channel being punctured.

[0289] Scenario 1.11: no puncturing in the 100MHz channel.

[0290] In this scenario, no puncturing in the 100MHz channel means that the 100MHz channel can be used for data transmission.

[0291] In an optional implementation, when there is no puncturing in the 100MHz channel, the lowest 80MHz in the 100MHz channel can correspond to a 996-tone RU, and the highest 20MHz can correspond to a 242-tone RU. Therefore, if there is no puncturing in the 100MHz channel, the 100MHz channel can include a 996+242-tone MRU, such as the 100MHz channel for transmitting the first PPDU including a 996+242-tone MRU. For example, FIG. 7 is a schematic diagram of the division of a 100MHz channel. The 100MHz channel in FIG. 7 has no puncturing, and the 100MHz channel includes a 996+242-tone MRU.

[0292] In a possible implementation, when the first PPDU is a UHR PPDU, the UHR-STF, UHR-LTF, Data, and PE in the first PPDU can be referred to as a UHR modulation part, which is transmitted in the 996+242-tone MRU.

[0293] A possible implementation manner includes, but is not limited to, at least one of the following channels including the 996+242-tone MRU: a 160 MHz channel, a 240 MHz channel, a 320 MHz channel, a 480 MHz channel, and a 640 MHz channel. That is, the 996+242-tone MRU can be an MRU format in multiple channels.

[0294] A possible implementation manner, when there is no punching in the 100 MHz, the 100 MHz channel can include a 484+484+242-tone MRU, or can include a 484+242+242+242-tone MRU, or can include a 242+242+242+242+242-tone MRU, wherein the 242-tone RU is a RU corresponding to one 20 MHz in the 100 MHz, and the 484-tone RU is a RU corresponding to one 40 MHz in the 100 MHz.

[0295] Scenario 1.12: 20 MHz in the 100 MHz is punched.

[0296] In the scenario, the 20 MHz in the 100 MHz is punched, which means that the 20 MHz in the 100 MHz is punched and cannot be used for data transmission, and then 80 MHz in the 100 MHz can be used for data transmission. In addition, the 20 MHz in the 100 MHz is punched, which can be that a 20 MHz subchannel in the 100 MHz channel is punched, for example, a 20 MHz subchannel in the 100 MHz channel for transmitting the first PPDU is punched.

[0297] In the scenario, the first PPDU further includes punching field indication information, and the punching field indication information is used to indicate that the 20 MHz in the 100 MHz is punched, and the 20 MHz is located in the lowest 80 MHz in the 100 MHz, or in other words, the punched 20 MHz is not the highest 20 MHz in the 100 MHz. Therefore, when the 20 MHz in the 100 MHz is punched, the first to fourth 20 MHz in the 100 MHz can be punched in order from low to high, or in other words, the first to fourth 20 MHz subchannels in the 100 MHz channel can be punched, and there are four punching modes.

[0298] A possible implementation manner is that the punching field indication information is a punching field. A possible implementation manner is that the first PPDU includes a U-SIG, and the U-SIG includes the punching field.

[0299] Referring to Table 5 below, Table 5 is the meaning of the punching field in the U-SIG for the OFDMA transmission mode.

[0300] Table 5

[0301] As can be seen from Table 5, when the value of the punch field is 0, it indicates that there is no punch in the 100MHz; when the value of the punch field is 1, it indicates that the first 20MHz is punched from low frequency to high frequency in the 100MHz; when the value of the punch field is 3, it indicates that the second 20MHz is punched from low frequency to high frequency in the 100MHz; when the value of the punch field is 4, it indicates that the third 20MHz is punched from low frequency to high frequency in the 100MHz. It can be seen that when the value of the punch field is 1 to 4, different 20MHz in the lowest 80MHz of the 100MHz channel is punched respectively.

[0302] In an optional implementation, when the 20MHz in the 100MHz is punched, there is a 484+242-tone MRU in the lowest 80MHz in the 100MHz, and there is a 242-tone RU in the highest 20MHz, so as to jointly constitute a 484+242+242-tone MRU, that is, the 100MHz channel can include the 484+242+242-tone MRU, for example, the 100MHz channel for transmitting the first PPDU includes the 484+242+242-tone MRU.

[0303] It should be noted that in the embodiments of the present application, the large-size RU is usually placed at the front of the MRU included in the 100MHz channel, but the position of the large-size RU and the position of the small-size RU do not represent the position of the large-size RU and the small-size RU in the 100MHz channel. In the 100MHz channel, the large-size RU can be located before the small-size RU, or the large-size RU can be located after the small-size RU, or the large-size RU can be located between multiple small-size RUs.

[0304] For example, when the 100MHz channel includes 484+242+242-tone MRU, the 484-tone RU is located before the two 242-tone RUs in the order of frequency from low to high, or the 484-tone RU is located after the two 242-tone RUs, or the 484-tone RU is located between the two 242-tone RUs, and the embodiments of the present application do not limit the location between the 484-tone RU and the two 242-tone RUs. In other words, when the 100MHz channel includes 484+242+242-tone MRU, the 484 subcarriers are located before the two 242 subcarriers, or the 484 subcarriers are located after the two 242 subcarriers, or the 484 subcarriers are located between the two 242 subcarriers, and the embodiments of the present application do not limit the location between the 484 subcarriers and the two 242 subcarriers.

[0305] For example, FIGS. 8 to 11 are diagrams of division of a 100MHz channel. As shown in FIG. 8, the first 20MHz in the 100MHz is punctured, the 100MHz channel includes 484+242+242-tone MRU, and the 484 subcarriers are located before the two 242 subcarriers. As shown in FIG. 9, the second 20MHz in the 100MHz is punctured, the 100MHz channel includes 484+242+242-tone MRU, and the 484 subcarriers are located between the two 242 subcarriers. As shown in FIG. 10, the third 20MHz in the 100MHz is punctured, the 100MHz channel includes 484+242+242-tone MRU, and the 484 subcarriers are located before the two 242 subcarriers. As shown in FIG. 11, the fourth 20MHz in the 100MHz is punctured, the 100MHz channel includes 484+242+242-tone MRU, and the 484 subcarriers are located before the two 242 subcarriers.

[0306] In addition, in the diagrams of division of the 100MHz channel shown in FIGS. 8 to 11, the RU corresponding to the highest 20MHz in the 100MHz can be regarded as an extension on the basis of the 80MHz defined in the protocol. Therefore, for the 100MHz channel shown in FIGS. 8 to 11, the 100MHz channel includes 484+242+242-tone MRU, which can also be replaced by: the 100MHz channel includes (484+242)+242-tone MRU.

[0307] In one possible implementation, the 100MHz channel includes a 484+242+242-tone MRU, and the 484 subcarriers of the 484+242+242-tone MRU are within the lowest 80MHz of the 100MHz, for example, as shown in FIGS. 8-11 above, where the 484 subcarriers are within the lowest 80MHz of the 100MHz.

[0308] In one possible implementation, the 100MHz channel includes a 484+242+242-tone MRU, and the 484 subcarriers of the 484+242+242-tone MRU are within the highest 40MHz of the 100MHz when 20MHz of the 100MHz is punctured. That is, when the 100MHz channel includes a 484+242+242-tone MRU, and the 484-tone RU can be defined across 80MHz, or where the 484 subcarriers are defined across 80MHz, so that the resources can be more flexibly utilized.

[0309] For example, FIGS. 12, 13, and 14 are diagrams illustrating a partitioning of a 100MHz channel. In FIGS. 12-14, the first, second, and third 20MHz of the 100MHz are punctured, and the highest 40MHz of the 100MHz corresponds to a 484-tone RU, and the lowest 60MHz corresponds to a 242+242-tone MRU. Thus, in FIGS. 12-14, the 100MHz channel includes a 484+242+242-tone MRU, and the 484-tone RU is defined across 80MHz.

[0310] In another alternative implementation, when 20MHz of the 100MHz is punctured, each contiguous 40MHz of the 100MHz that is not punctured corresponds to a 484-tone MRU, so that the 484-tone MRUs together form a 484+484-tone MRU, i.e., the 100MHz channel includes a 484+484-tone MRU, such as the 100MHz channel transmitting the first PPDU. In this case, the two 484 subcarriers of the 484+484-tone MRU are contiguous, or non-contiguous; or the two 484 subcarriers of the 484+484-tone MRU are contiguous, or non-contiguous. In addition, when the 100MHz channel includes a 484+484-tone MRU, and one of the contiguous 484 subcarriers is within the highest 40MHz of the 100MHz, the contiguous 484 subcarriers can be considered to be defined across 80MHz, so that the resources can be more flexibly utilized.

[0311] For example, FIG. 15 and FIG. 16 are diagrams illustrating a division of a 100 MHz channel, respectively. As shown in FIG. 15, the lowest 20 MHz in the 100 MHz is punctured, the second 20 MHz and the third 20 MHz in the 100 MHz combine to correspond to a 484-tone MRU, the fourth 20 MHz and the fifth 20 MHz combine to correspond to a 484-tone MRU, and together they form a 484+484-tone MRU, and the two 484 subcarriers are continuous, so that the 100 MHz channel includes the 484+484-tone MRU, and the two 484 subcarriers in the 484+484-tone MRU are continuous, wherein the 484 subcarriers in the high frequency band are defined across 80 MHz. As shown in FIG. 16, the third 20 MHz in the 100 MHz is punctured, the first 20 MHz and the second 20 MHz in the 100 MHz combine to correspond to a 484-tone MRU, the fourth 20 MHz and the fifth 20 MHz combine to correspond to a 484-tone MRU, and together they form a 484+484-tone MRU, and the two 484 subcarriers are discontinuous, so that the 100 MHz channel includes the 484+484-tone MRU, and the two 484 subcarriers in the 484+484-tone MRU are discontinuous, wherein the 484 subcarriers in the high frequency band are defined across 80 MHz.

[0312] In a possible implementation, when 20 MHz in the 100 MHz is punctured, the 100 MHz channel includes a 484+484-tone MRU in a manner in which one of the 484 subcarriers is combined from two discontinuous 242 subcarriers, i.e., one of the 484 subcarriers is discontinuous. For example, FIG. 17 and FIG. 18 are diagrams illustrating a division of a 100 MHz channel, respectively. As shown in FIG. 17, the second 20 MHz in the 100 MHz is punctured, the first 20 MHz and the third 20 MHz can form a discontinuous 484-tone RU, i.e., the 484 subcarriers in the 484-tone RU are combined from two discontinuous 242 subcarriers, the fourth 20 MHz and the fifth 20 MHz form a continuous 484-tone RU, and further can form a 484+484-tone MRU, and the 484 subcarriers in the high frequency band are defined across 80 MHz.

[0313] As shown in FIG. 18, the fourth 20MHz in the 100MHz is punctured, the first 20MHz and the second 20MHz can constitute a continuous 484-tone RU, the third 20MHz and the fifth 20MHz can constitute a discontinuous 484-tone RU, and further can constitute a 484+484-tone MRU.

[0314] In another alternative implementation, when 20MHz in the 100MHz is punctured, and the 80MHz not punctured corresponds to a 996-tone RU, the 100MHz channel includes a 996-tone RU, such as the 100MHz channel transmitting the first PPDU includes a 996-tone RU. In this case, the 996 subcarriers in the 996-tone RU are continuous or discontinuous, such as the 996 subcarriers in the 996-tone RU are composed of two discontinuous 484 subcarriers.

[0315] For example, FIG. 19 and FIG. 20 are diagrams of division of a 100MHz channel. As shown in FIG. 19, the first 20MHz in the 100MHz is punctured, and the continuous 80MHz not punctured corresponds to a 996-tone RU, so that the 100MHz channel includes a 996-tone RU, and the 996 subcarriers in the 996-tone RU are continuous. In addition, the 996-tone RU in the 100MHz channel shown in FIG. 19 is also defined across 80MHz, which can more flexibly utilize resources.

[0316] As shown in FIG. 20, the third 20MHz in the 100MHz is punctured, the first 20MHz and the second 20MHz are combined to correspond to a 484 subcarrier, the fourth 20MHz and the fifth 20MHz are also combined to correspond to a 484 subcarrier, and the two discontinuous 484 subcarriers can constitute a discontinuous virtual 996 subcarrier, i.e., a 996-tone RU. In addition, the subcarriers in the 996-tone RU located in the high frequency band are also defined across 80MHz, which can more flexibly utilize resources.

[0317] In the 100MHz including 484+484-tone MRU, and the 484 subcarriers in the 484+484-tone MRU are discontinuous, and in the 100MHz including 996-tone RU, and the 996 subcarriers in the 996-tone RU are discontinuous, whether the non-continuous 484 subcarriers and the non-continuous 996 subcarriers need to reserve the DC component needs to be considered. Since the DC component part cannot be used to transmit information, two non-continuous 242 subcarriers cannot be combined into a 484-tone RU, and two non-continuous 484 subcarriers cannot be combined into a 996-tone RU. That is, when the DC component overlaps with part of the two non-continuous 242 subcarriers, the two non-continuous 242 subcarriers cannot be combined into a 484-tone RU. Similarly, when the DC component overlaps with part of the two non-continuous 484 subcarriers, the two non-continuous 484 subcarriers cannot be combined into a 996-tone RU. This mode can guarantee that the 100MHz PPDU can successfully transmit information.

[0318] It can be seen that in the non-OFDMA transmission, if the 20MHz in the 100MHz is punctured, the 100MHz channel includes 484+242+242-tone MRU, or the 100MHz channel includes 484+484-tone MRU, or the 100MHz channel includes 996-tone RU.

[0319] Scenario 1.13: 40MHz in 100MHz is punctured.

[0320] Among them, 40MHz in 100MHz is punctured, which means that 40MHz in 100MHz is punctured and cannot be used to transmit data, so that 60MHz in 100MHz can be used to transmit data. In addition, the 40MHz in the 100MHz is punctured, which can be that the 40MHz subchannel in the 100MHz channel is punctured, such as the 40MHz subchannel in the 100MHz channel transmitting the first PPDU is punctured.

[0321] In this scenario, the first PPDU further includes puncturing field indication information, and the puncturing field indication information is used to indicate that 40MHz in 100MHz is punctured, and the 40MHz is located in the lowest 80MHz in 100MHz, or in other words, the punctured 40MHz does not include the highest 20MHz in 100MHz. Therefore, when the 40MHz in the 100MHz is punctured, the continuous 40MHz in the first to fourth 20MHz in the 100MHz can be punctured, and there are three puncturing modes.

[0322] In a possible implementation, the puncturing field indication information is a puncturing field. In a possible implementation, the first PPDU includes a U-SIG, and the U-SIG includes the puncturing field. The meaning of the puncturing field can be found in Table 5.

[0323] As can be seen from Table 5, when the value of the bandwidth field is 5, it indicates that the lowest 40 MHz in the 100 MHz is punctured; when the value of the bandwidth field is 6, it indicates that, from low frequency to high frequency in the 100 MHz, the second 20 MHz and the third 20 MHz are punctured; and when the value of the bandwidth field is 7, it indicates that, from low frequency to high frequency in the 100 MHz channel, the third 20 MHz and the fourth 20 MHz are punctured.

[0324] In an optional implementation, when the 40 MHz in the 100 MHz is punctured, one of the continuous 40 MHz that is not punctured corresponds to a 484-tone RU, and one of the 20 MHz that is not punctured corresponds to a 242-tone RU, so as to jointly form a 484+242-tone MRU. That is, the 100 MHz channel can include the 484+242-tone MRU, and the 100 MHz that transmits the first PPDU can include the 484+242-tone MRU. For example, FIGS. 21 to 23 are schematic diagrams of division of a 100 MHz channel. As shown in FIGS. 21 to 23, the 40 MHz in the 100 MHz is punctured, and the 100 MHz channel includes the 484+242-tone MRU. The 484-tone RU is a RU corresponding to the continuous 40 MHz that is not punctured in the 100 MHz, and the 242-tone RU is a RU corresponding to one of the 20 MHz that is not punctured in the 100 MHz. In addition, in the 100 MHz channel shown in FIG. 22, the 484-tone RU is defined across 80 MHz, and the resource can be more flexibly utilized.

[0325] In another optional implementation, when the 20 MHz in the 100 MHz is punctured, each of the 20 MHz that is not punctured corresponds to a 242-tone RU, so as to jointly form a 242+242+242-tone MRU. That is, the 100 MHz channel can include the 242+242+242-tone MRU, and the 100 MHz channel that transmits the first PPDU can include the 242+242+242-tone MRU. For example, FIGS. 24 to 26 are schematic diagrams of division of a 100 MHz channel. As shown in FIGS. 24 to 26, the 40 MHz in the 100 MHz is punctured, and the 100 MHz channel includes the 242+242+242-tone MRU. Each of the 242-tone RUs is a RU corresponding to each of the 20 MHz that is not punctured in the 100 MHz.

[0326] In a possible implementation, when the 100MHz channel includes 242+242+242-tone MRU, any two 242-tone MRUs can also form a 484-tone RU, including two 242-tone MRUs located in different 80MHz. For example, the 242-tone RU corresponding to the first 20MHz in FIG. 25 and the 242-tone RU corresponding to the fourth 20MHz can form a non-contiguous 484 subcarriers, i.e., form a 484-tone RU, so that the 100MHz channel includes 484+242-tone MRU, and the 484 subcarriers in the 484+242-tone MRU are non-contiguous.

[0327] As can be seen, in non-OFDMA transmission, when 40MHz in the 100MHz is punctured, the 100MHz channel includes 484+242-tone MRU, or the 100MHz channel includes 242+242+242-tone MRU.

[0328] It should be noted that the puncturing field shown in Table 5 above can indicate the division manner of the 100MHz channel, or in other words, can indicate the RU / MRU included by the 100MHz channel. In other words, the puncturing mode indicated by the puncturing field of the first PPDU can correspond to the RU / MRU included by the 100MHz.

[0329] Transmission mode 1.2: OFDMA transmission.

[0330] Compared with non-OFDMA transmission, in OFDMA transmission, the first device can respectively allocate frequency domain resources to different users. Therefore, the first device can directly use the RU or MRU type defined by the protocol without defining a new RU or MRU type, so as to reduce the implementation complexity. In a possible implementation, the first device can also redefine the RU or MRU type, so as to more flexibly utilize the resources and schedule users.

[0331] Similar to non-OFDMA transmission, in OFDMA transmission, the 100MHz can be punctured or not punctured. When the 100MHz is punctured, 20MHz in the 100MHz is punctured, or 40MHz in the 100MHz is punctured. The following also respectively describes the implementation of the 100MHz channel in the OFDMA transmission mode in the following scenarios: the scenario that the 100MHz is not punctured, the scenario that 20MHz in the 100MHz is punctured, and the scenario that 40MHz in the 100MHz is punctured.

[0332] Scenario 1.21: The 100MHz is not punctured.

[0333] In this scenario, 100MHz can be used to transmit information. The first device can not redefine a new RU or MRU, such as directly allocating resources in 80MHz of 100MHz to one or more users, and allocating resources in the remaining 20MHz of 100MHz to another one or more users.

[0334] In an alternative embodiment, when there is no puncturing in 100MHz, 100MHz can include one 484+242-tone MRU and two 242-tone RUs, such as the 100MHz channel used to transmit the first PPDU including one 484+242-tone MRU and two 242-tone RUs. In this way, the first device defines a 484+242-tone MRU across 80MHz, and can more flexibly use resources. For example, FIG. 27 is a schematic view of another division of a 100MHz channel, as shown in FIG. 27, the 100MHz channel includes one 484+242-tone MRU and two 242-tone RUs, wherein the 484+242-tone MRU corresponding to the highest 60MHz of 100MHz is defined across 80MHz.

[0335] In another alternative embodiment, when there is no puncturing in 100MHz, the 100MHz channel can include one 484-tone RU and three 242-tone RUs, such as the 100MHz channel used to transmit the first PPDU including one 484-tone RU and three 242-tone RUs. For example, FIG. 28 is a schematic view of another division of a 100MHz channel, as shown in FIG. 28, the 100MHz channel includes one 484-tone RU and three 242-tone RUs.

[0336] In another alternative embodiment, when there is no puncturing in 100MHz, the 100MHz channel can include five 242-tone RUs, such as the 100MHz channel used to transmit the first PPDU including five 242-tone RUs. For example, FIG. 29 is a schematic view of another division of a 100MHz channel, as shown in FIG. 29, the 100MHz channel includes five 242-tone RUs.

[0337] In yet another alternative implementation, when there is no puncturing in the 100MHz, the 100MHz channel can include one 242-tone RU and two 484-tone RUs, such as the 100MHz channel transmitting the first PPDU includes one 242-tone RU and two 484-tone RUs. For example, FIG. 30 is an illustration of yet another partition of a 100MHz channel, as shown in FIG. 30, the 100MHz channel includes one 242-tone RU and two 484-tone RUs.

[0338] In yet another alternative implementation, when there is no puncturing in the 100MHz, the 100MHz channel can include one 242-tone RU and one 996-tone RU, such as the 100MHz channel transmitting the first PPDU includes one 242-tone RU and one 996-tone RU. For example, FIG. 31 is an illustration of yet another partition of a 100MHz channel, as shown in FIG. 31, the 100MHz channel includes one 242-tone RU and one 996-tone RU. In addition, in the 100MHz channel shown in FIG. 31, the 996-tone RU is defined across 80MHz, which can be more flexible in utilizing the resources.

[0339] In yet another alternative implementation, when there is no puncturing in the 100MHz, the 100MHz channel can include one 484+242-tone MRU and one 484-tone RU, such as the 100MHz channel transmitting the first PPDU includes one 484+242-tone MRU and one 484-tone RU. For example, FIG. 32 is an illustration of yet another partition of a 100MHz channel, as shown in FIG. 32, the 100MHz channel includes one 484+242-tone MRU and one 484-tone RU. In addition, in the 100MHz channel shown in FIG. 32, the 484-tone RU in the high frequency band is defined across 80MHz, which can be more flexible in utilizing the resources.

[0340] It can be seen that when there is no puncturing in the 100MHz, the first device can directly use the defined RU or MRU types to partition the 100MHz channel in the manner shown in FIGS. 28, 29 and 30 to reduce the implementation complexity without defining new RU or MRU types. In addition, when there is no puncturing in the 100MHz, the first device can also define the RUs across 80MHz in the manner shown in FIGS. 27, 31 and 32, which can be more flexible in utilizing the resources.

[0341] Scenario 1.22: 20MHz in 100MHz is punctured.

[0342] In this scenario, the first PPDU further comprises puncturing field indication information, which is used to indicate that 20MHz in 100MHz is punctured, and the 20MHz is located in the lowest 80MHz in 100MHz. The meaning of the puncturing field indication information and the puncturing mode can be referred to the description in scenario 1.12, and will not be described herein.

[0343] However, the specific form of the puncturing field indication information in this scenario is different from that in scenario 1.12. For OFDMA transmission, the lowest 80MHz in 100MHz corresponds to one 4-bit puncturing indication, the highest 20MHz in 100MHz corresponds to one 4-bit puncturing indication, and the 4-bit of the highest 20MHz is 1111. The 4-bit of the lowest 80MHz in 100MHz is used to indicate the puncturing of 20MHz in the lowest 80MHz, and the 1111 of the highest 20MHz is used to indicate that the highest 20MHz is not punctured. That is, for OFDMA transmission, for the first PPDU of 100MHz, there are two 4-bit puncturing indication information, one 4-bit puncturing indication information corresponds to the lowest 80MHz in 100MHz, and is used to indicate the puncturing of 20MHz in the lowest 80MHz; the other 4-bit is set to 1111, and is used to indicate that the highest 20MHz in 100MHz is not punctured.

[0344] In OFDMA transmission, when the puncturing field indication information is the puncturing field, the meaning of the puncturing field can be referred to Table 6 shown below:

[0345] Table 6

[0346] In Table 6, the domain value-1 is one 4-bit corresponding to the lowest 80MHz in 100MHz, and the domain value-2 is one 4-bit corresponding to the highest 20MHz in 100MHz. The value of the domain value-1 represents the puncturing mode of 20MHz in the lowest 80MHz in 100MHz, for example, the value of the domain value-1 is 0111, which indicates that the lowest 20MHz in the lowest 80MHz is punctured. The value of the domain value-2 is 1111, which represents that the highest 20MHz in 100MHz is not punctured, thereby guaranteeing the transmission resource of 100MHz.

[0347] In addition, when 20MHz in 100MHz is punctured, the channel division manner of 100MHz can refer to the channel division manner of 100MHz in scenario 1.12. For example, when 20MHz in 100MHz is punctured, the 100MHz channel includes 484+242+242-tone MRU, and the 100MHz channel for transmitting the first PPDU includes 484+242+242-tone MRU. For another example, when 20MHz in 100MHz is punctured, the 100MHz channel includes 484+484-tone MRU, and the 100MHz channel for transmitting the first PPDU can include 484+484-tone MRU, and the two 484 subcarriers in the 484+484-tone MRU are continuous or discontinuous. For another example, when 20MHz in 100MHz is punctured, the 100MHz channel includes 996-tone RU, and the 100MHz channel for transmitting the first PPDU can include 996-tone RU, and the 996 subcarriers in the 996-tone RU are continuous or discontinuous.

[0348] Scenario 1.23: 40MHz in 100MHz is punctured.

[0349] In this scenario, the first PPDU further includes puncture field indication information, and the puncture field indication information is used to indicate that 40MHz in 100MHz is punctured, and the 40MHz is located in the lowest 80MHz in 100MHz. Wherein, the meaning indicated by the puncture field indication information, and the puncture mode can refer to the description in scenario 1.13, and will not be repeated here.

[0350] However, the specific form of the puncture field indication information in this mode is not the same as the specific form of the puncture field indication information in scenario 1.13. For OFDMA transmission, the lowest 80MHz in 100MHz corresponds to a 4-bit puncture indication, the highest 20MHz corresponds to a 4-bit puncture indication, and the highest 20MHz corresponds to a 4-bit 1111. Among them, the 4-bit corresponding to the lowest 80MHz in 100MHz is used to indicate the puncture of 40MHz in the lowest 80MHz, and the 1111 corresponding to the highest 20MHz is used to indicate that the highest 20MHz is not punctured. That is, for OFDMA transmission, for the first PPDU of 100MHz, there are two 4-bit puncture indication information, one 4-bit puncture indication information corresponds to the lowest 80MHz in 100MHz, and is used to indicate the puncture of 40MHz in the lowest 80MHz; another bit is set to 1111, and is used to indicate that the highest 20MHz in 100MHz is not punctured.

[0351] For OFDMA transmission, the puncturing field indicates the information of the puncturing field, and the puncturing field indicates 40MHz in 100MHz being punctured in multiple cases. Referring to Table 6, the multiple cases are not described again.

[0352] In addition, when 40MHz in 100MHz is punctured, the channel division mode of 100MHz can refer to the division mode of 100MHz channel in scenario 1.13. For example, when 40MHz in 100MHz is punctured, the 100MHz channel can include a 484+242-tone MRU, such as the 100MHz channel transmitting the first PPDU can include a 484+242-tone MRU. For another example, when 40MHz in 100MHz is punctured, the 100MHz channel can include a 242+242+242-tone MRU, such as the 100MHz channel transmitting the first PPDU can include a 242+242+242-tone MRU.

[0353] It should be noted that the puncturing field shown in Table 6 can indicate the division mode of the 100MHz channel, or in other words, can indicate the RU / MRU included in the 100MHz channel.

[0354] In addition, for OFDMA transmission, if the first PPDU includes a UHR-SIG field, there will be a resource unit allocation (RU Allocation) field in the common part of the UHR-SIG field, which is used for RU or MRU allocation of users and for indicating the number of users corresponding to the allocated RU or MRU. Generally, each 242-tone RU range will correspond to an RU Allocation field. Thus, for the first PPDU occupying 100MHz, there are a total of 5 RU Allocation fields (labeled RU Allocation #1 to RU Allocation #5 from low to high in frequency). Further, in an 80MHz frequency sub-block, two content channels (CCs) are usually defined, different contents are carried in different 20MHz sub-channels to improve transmission efficiency.

[0355] For 100MHz OFDMA transmission or Non-OFDMA MU-MIMO transmission, each CC carries in a 20MHz. In the lowest 80MHz of 100MHz, it is a repeating mode of CC1, CC2, CC1, CC2; in the highest 20MHz of 100MHz, there is CC1, and the content can be different from the content of CC1 in the lowest 80MHz, so it can also be marked as CC3.

[0356] That is, the 100MHz channel transmitting the first PPDU includes the first content channel and the second content channel in the low 80MHz and includes the third content channel in the high 20MHz. In one possible implementation, the first PPDU includes a UHR-SIG, the UHR-SIG includes the first content channel and the second content channel in the low 80MHz and includes the third content channel in the high 20MHz.

[0357] In one optional implementation, the first content channel and the third content channel each carries three resource unit allocation fields, and the second content channel carries two resource unit allocation fields, the resource unit allocation fields carried by the first content channel, the second content channel and the third content channel are used to indicate the allocation of RUs or MRUs.

[0358] For example, the first content channel is CC1, the second content channel is CC2, and the third content channel is CC3, where CC1 and CC2 are CCs included in the lower 80 MHz of the 100 MHz channel, and CC3 is a CC included in the upper 20 MHz of the 100 MHz channel. FIG. 33 is a diagram of an example of resource unit allocation information. As shown in FIG. 33, the UHR-SIG includes CC1, CC2, and CC3, which are repeated for CC1, CC2, CC1, CC2 within the lower 80 MHz of the 100 MHz channel. CC1 and CC2 carry RU Allocation #1, RU Allocation #2, RU Allocation #3, RU Allocation #4, and RU Allocation #5 in order from low to high frequency. Thus, CC1 carries RU Allocation #1, RU Allocation #3, and RU Allocation #5, and CC2 carries RU Allocation #2 and RU Allocation #4. CC3 carries the same RUs as CC1, i.e., CC3 carries RU Allocation #1, RU Allocation #3, and RU Allocation #5. Each RU Allocation carried by CC1, CC2, and CC3 indicates an allocation of RUs or MRUs, and CC1 and CC3 need to indicate the same allocation of RUs or MRUs, including RU or MRU size and location. In one possible implementation, the number of users indicated by each RU Allocation carried by CC3 can be different from the number of users indicated by each RU Allocation carried by CC1, e.g., the number of users indicated by RU Allocation #1 carried by CC3 can be different from the number of users indicated by RU Allocation #1 carried by CC1. In another possible implementation, the number of users indicated by each RU Allocation carried by CC3 can be the same as the number of users indicated by each RU Allocation carried by CC1, e.g., the number of users indicated by RU Allocation #1 carried by CC3 can be the same as the number of users indicated by RU Allocation #1 carried by CC1, in which case CC1 and CC3 are the same.

[0359] As shown in FIG. 33, each CC also carries a cyclic redundancy code (CRC) and a Tail. The CRC is used to check whether the bits of a code block are transmitted correctly, and the Tail is a tail part, which is set to 0 and used to terminate the trellis of a convolutional decoder. The end of the Tail in each CC can mark the end of a field, and the field can be referred to as a common field of the CC. In addition, each CC also carries a U-SIG overflow field, which is used to carry common information that cannot be carried by the U-SIG.

[0360] In a possible implementation, the common field of the first content channel is located in a first common code block, the common field of the second content channel is located in a second common code block, and the common field of the third content channel is located in a third common code block. The first common code block and the third common code block each carry three resource unit allocation fields, and the second common code block carries two resource unit allocation fields. Alternatively, in a case where the first content channel and the third content channel each carry three resource unit allocation fields, and the second content channel carries two resource unit allocation fields, the common field of the first content channel, the common field of the second content channel, and the common field of the third content channel are located in a common code block respectively. This manner can save the overhead of CRC and Tail.

[0361] For example, FIGS. 34 to 36 are schematic diagrams of resource unit allocation information. As shown in FIG. 34, the common fields corresponding to RU Allocation#1, RU Allocation#3, and RU Allocation#5 carried by CC1 are located in a common code block 11. As shown in FIG. 35, the common fields corresponding to RU Allocation#2, RU Allocation#4 carried by CC2 are located in a common code block 21. As shown in FIG. 36, the common fields corresponding to RU Allocation#1, RU Allocation#3, and RU Allocation#5 carried by CC3 are located in a common code block 31.

[0362] In addition, in FIG. 34 to FIG. 36, a user code block, such as user code block 11, is also included, which carries a user identification, and the user identification carried corresponds to the allocation of the RU or MRU indicated by the RU Allocation of the common code block. For example, in FIG. 34, the RU or MRU allocated by the RU Allocation #1, RU Allocation #3 and RU Allocation #5 carried by the common code block 11 corresponds to the user identification carried by the user code block 11, or is understood that the RU or MRU allocated by the RU Allocation #1, RU Allocation #3 and RU Allocation #5 carried by the common code block 11 is allocated to the user corresponding to the user identification carried by the user code block 11. Similarly, the user code block and the common code block in the following resource unit allocation information diagrams have the same understanding, and will not be repeated.

[0363] In a possible implementation, the common field of the first content channel is located in the first common code block and the second common code block, the common field of the second content channel is located in the third common code block, the common field of the third content channel is located in the fourth common code block and the fifth common code block, the first common code block, the third common code block and the fourth common code block respectively carry two resource unit allocation fields, and the second common code block and the fifth common code block respectively carry one resource unit allocation field. In other words, in the case that the first content channel and the third content channel respectively carry three resource unit allocation fields, and the second content channel carries two resource unit allocation fields, the common field of the first content channel and the common field of the third content channel are respectively located in two common code blocks, and the common field of the second content channel is located in one common code block.

[0364] For example, FIG. 37 to FIG. 39 are respectively a resource unit allocation information diagram. As shown in FIG. 37, the common field corresponding to the RU Allocation #1 and RU Allocation #3 carried by the CC1 is located in the common code block 11, and the common field corresponding to the RU Allocation #5 carried by the CC1 is located in the common code block 12. As shown in FIG. 38, the common field corresponding to the RU Allocation #2 and RU Allocation #4 carried by the CC2 is located in the common code block 21. As shown in FIG. 39, the common field corresponding to the RU Allocation #1 and RU Allocation #3 carried by the CC3 is located in the common code block 31, and the common field corresponding to the RU Allocation #5 carried by the CC1 is located in the common code block 32.

[0365] It can be seen that the first content channel and the third content channel respectively carry three resource unit allocation fields, and the second content channel carries two resource unit allocation fields. In the case that the resource unit allocation fields respectively carried by the first content channel, the second content channel and the third content channel are used to indicate the allocation of RUs or MRUs, the common fields of the first content channel, the second content channel and the third content channel are respectively located in one common encoding block, or the common fields of the first content channel and the third content channel are respectively located in two common encoding blocks, and the common field of the second content channel is located in one common encoding block.

[0366] In another optional implementation, the first content channel, the second content channel and the third content channel respectively carry three resource unit allocation fields. Among them, the first content channel and the third content channel respectively carry three resource unit allocation fields used to indicate the allocation of RUs or MRUs; and the second content channel carries three resource unit allocation fields, two of which are used to indicate the allocation of RUs or MRUs, and one is a reserved field or used to indicate puncturing information or used to indicate reserved information. In a possible implementation, the one resource unit allocation field carried by the second content channel can be replaced by a reserved field.

[0367] The first content channel, the second content channel and the third content channel all carry three resource unit allocation fields, which can ensure that the lengths of the common fields in different content channels are equal, and is beneficial to decoding and parsing by the receiving end (such as the second device).

[0368] For example, the first content channel is CC1, the second content channel is CC2, and the third content channel is CC3, wherein CC1 and CC2 are CCs included in the low 80MHz of the 100MHz channel transmitting the first PPDU, and CC3 is a CC included in the high 20MHz of the 100MHz channel. FIG. 40 is a schematic diagram of another resource unit allocation information. As shown in FIG. 40, CC1 and CC3 both carry RU Allocation#1, RU Allocation#3, and RU Allocation#5, and CC2 carries RU Allocation#2, RU Allocation#4, and RU Allocation#6. The RU Allocation#1, RU Allocation#3, and RU Allocation#5 carried by CC1 and CC3, and the RU Allocation#2 and RU Allocation#4 carried by CC2 are used to indicate the allocation of RUs or MRUs, and the RU Allocation#6 carried by CC2 is used to indicate puncturing information or is used to indicate reservation information. In one possible implementation, the RU Allocation#6 carried by CC2 can be replaced by a reserved field, i.e., a reserved field is arranged after the RU Allocation#4 carried by CC2, instead of an RU Allocation field.

[0369] In one possible implementation, the common field of the first content channel is located in a first common coding block, the common field of the second content channel is located in a second common coding block, and the common field of the third content channel is located in a third common coding block, and the first common coding block, the second common coding block, and the third common coding block respectively carry the three resource unit allocation fields. Alternatively, in the case where the first content channel, the second content channel, and the third content channel respectively carry the three resource unit allocation fields, the common field of the first content channel, the common field of the second content channel, and the common field of the third content channel are respectively located in a common coding block.

[0370] For example, FIGS. 41 to 43 are respectively a schematic diagram of a resource unit allocation information. As shown in FIG. 41, the common field corresponding to the RU Allocation#1, the RU Allocation#3, and the RU Allocation#5 carried by CC1 is located in a common coding block 11. As shown in FIG. 42, the common field corresponding to the RU Allocation#2, the RU Allocation#4, and the RU Allocation#6 or the reserved field carried by CC2 is located in a common coding block 21. As shown in FIG. 43, the common field corresponding to the RU Allocation#1, the RU Allocation#3, and the RU Allocation#5 carried by CC3 is located in a common coding block 31.

[0371] In a possible implementation, the common field of the first content channel is located in the first common coding block and the second common coding block, the common field of the second content channel is located in the third common coding block and the fourth common coding block, and the common field of the third content channel is located in the fifth common coding block and the sixth common coding block. The first common coding block, the third common coding block, and the fifth common coding block respectively carry two resource unit allocation fields, and the second common coding block, the fourth common coding block, and the sixth common coding block respectively carry one resource unit allocation field. Alternatively, the first common coding block, the third common coding block, and the fifth common coding block respectively carry two resource unit allocation fields, and the second common coding block, the fourth common coding block, and the sixth common coding block respectively carry one reserved field. Alternatively, in the case that the first content channel, the second content channel, and the third content channel respectively carry three resource unit allocation fields, the common field of the first content channel, the common field of the second content channel, and the common field of the third content channel are respectively located in two common coding blocks.

[0372] For example, FIGS. 44 to 46 are respectively schematic diagrams of resource unit allocation information. As shown in FIG. 44, the common field corresponding to the RU Allocation#1 and the RU Allocation#3 carried by the CC1 is located in the common coding block 11, and the common field corresponding to the RU Allocation#5 is located in the common coding block 12. As shown in FIG. 45, the common field corresponding to the RU Allocation#2 and the RU Allocation#4 carried by the CC2 is located in the common coding block 21, and the common field corresponding to the RU Allocation#6 or the reserved field is located in the common coding block 22. As shown in FIG. 46, the common field corresponding to the RU Allocation#1 and the RU Allocation#3 carried by the CC3 is located in the common coding block 31, and the common field corresponding to the RU Allocation#5 is located in the common coding block 32.

[0373] It can be seen that, in the case that the first content channel, the second content channel, and the third content channel respectively carry three resource unit allocation fields, the common field of the first content channel, the common field of the second content channel, and the common field of the third content channel are respectively located in one common coding block, or the common field of the first content channel, the common field of the second content channel, and the common field of the third content channel are respectively located in two common coding blocks.

[0374] S102. The first device transmits a first PPDU by using a 100MHz channel.

[0375] S103. The second device receives the first PPDU.

[0376] S104. The second device parses the first PPDU.

[0377] The second device parses the first PPDU, including: reading bandwidth field indication information of the first PPDU, and obtaining, through the bandwidth field indication information, that the first PPDU occupies a bandwidth of 100 MHz. In a possible implementation, the second device reads a bandwidth field in a U-SIG of the first PPDU, and obtains, through the bandwidth field, that the first PPDU occupies a bandwidth of 100 MHz.

[0378] In a possible implementation, the second device further reads puncturing field indication information of the first PPDU, obtains, through the puncturing field indication information, puncturing conditions in a 100-MHz channel in which the first PPDU is transmitted, and then can obtain a channel carrying data information according to the puncturing conditions of the 100 MHz, and further obtain the data information carried in the channel. In a possible implementation, the second device reads a puncturing field in a U-SIG of the first PPDU, obtains, through the puncturing field, puncturing conditions in a 100-MHz channel in which the first PPDU is transmitted, and then obtains data information from a channel that is not punctured.

[0379] In an optional implementation, the 100 MHz belongs to a frequency range of 5735 MHz to 5835 MHz in an unlicensed frequency band, for example, the 100 MHz used to transmit the first PPDU belongs to the frequency range of 5735 MHz to 5835 MHz in the unlicensed frequency band. In this mode, the first device can fully use the 100 MHz corresponding to the frequency range of 5735 MHz to 5835 MHz in the unlicensed frequency band to transmit data, that is, the frequency spectrum utilization of 5.8 GHz can be maximized, the frequency spectrum utilization and system throughput are improved, and the time delay is reduced.

[0380] In addition, the spectrum of the unlicensed frequency band UNII-2A part needs to be matched with dynamic spectrum selection (DFS) and transmit power control (TPC) to detect signals such as weather radars, which is relatively complex and easy to produce false alarms, so it is relatively difficult to use a spectrum greater than 80 MHz at 5.1 GHz. When the 100 MHz belongs to the frequency range of 5735 MHz to 5835 MHz in the unlicensed frequency band, the use of the 100-MHz channel is added in the UNII-3 part, and the use of the spectrum greater than 80 MHz can be more easily realized.

[0381] In a possible implementation, the 100 MHz belongs to a licensed frequency band, for example, the 100 MHz used to transmit the first PPDU belongs to a licensed frequency band. In this mode, when there is a 100-MHz relative available bandwidth in some environment, the first device can fully use the 100 MHz to transmit data, and the frequency spectrum utilization can be improved.

[0382] In a possible implementation, the first device can further transmit a PPDU of 160 MHz to the second device under the condition that the first device transmits a first PPDU of 100 MHz to the second device. That is, the first device can use 160 MHz of 5.1 GHz and 100 MHz of 5.8 GHz for transmission in combination with multi-link operation (MLO), so as to maximize the spectrum utilization of 5 GHz.

[0383] It can be seen that in the embodiment of the application, the first device generates a first PPDU of 100 MHz, and transmits the first PPDU to the second device by using a 100 MHz channel, so as to realize 100 MHz data transmission. Compared with the transmission of information by using a PPDU defined by a protocol, the method can improve the spectrum utilization.

[0384] The embodiment of the application further provides another communication method 200, and FIG. 47 is an interaction schematic diagram of the communication method 200. The communication method 200 is also described from the perspective of the interaction between the first device and the second device. The communication method 200 includes but is not limited to the following steps:

[0385] S201. The first device generates a first PPDU, and the first PPDU includes bandwidth field indication information and puncturing field indication information. The bandwidth field indication information is used to indicate that the bandwidth of the first PPDU is 160 MHz, and the puncturing field indication information is used to indicate that the highest 60 MHz in the 160 MHz is punctured.

[0386] In a possible implementation, the first PPDU includes general signaling field indication information, and the general signaling field indication information includes bandwidth field indication information and puncturing field indication information. In addition, the general signaling field indication information can be a general signaling field, the bandwidth field indication information can be information used to indicate a bandwidth, for example, the bandwidth field indication information is a bandwidth field, and the bandwidth field is used to indicate that the bandwidth of the first PPDU is 160 MHz; the puncturing field indication information can be information used to indicate a puncturing mode, for example, the puncturing field indication information is a puncturing field, and the puncturing field is used to indicate the first PPDU.

[0387] In an optional implementation, the first PPDU includes a U-SIG, and the U-SIG includes a bandwidth field and a puncturing field. The value of the bandwidth field in the U-SIG is 3, which indicates that the bandwidth of the first PPDU is 160 MHz. In addition, the puncturing field in the U-SIG is used to indicate that the highest 60 MHz in the 160 MHz is punctured, and then the first PPDU actually occupies a bandwidth of 100 MHz.

[0388] It can be seen that the first device can indicate the bandwidth of the first PPDU as 160MHz through the bandwidth field in the U-SIG, and indicate that the highest 60MHz in the 160MHz is punctured through the puncturing field in the U-SIG, so that the first PPDU actually occupies a bandwidth of 100MHz.

[0389] In a possible implementation, the puncturing field indication information does not indicate that the highest 60MHz in the 160MHz is punctured, but indicates that the lowest 60MHz in the 160MHz is punctured, so that the first PPDU also actually occupies a bandwidth of 100MHz.

[0390] In an optional implementation, the first PPDU is a UHR PPDU, which can be referred to in S101 described above, and will not be described here. In a possible implementation, the first PPDU can be a PPDU in a standard after 802.11bn, which is not limited by the embodiments of the application. For ease of description, the following takes the first PPDU as a UHR PPDU as an example for description.

[0391] In addition, the transmission mode of the first PPDU includes non-OFDMA transmission and OFDMA transmission. The following describes the implementation of the 100MHz channel for the two transmission modes of non-OFDMA transmission and OFDMA transmission respectively:

[0392] Transmission mode 2.1: non-OFDMA transmission.

[0393] In non-OFDMA transmission, it is necessary to redefine the MRU in the 100MHz channel actually occupied by the first PPDU. In addition, the 100MHz channel actually occupied by the first PPDU can not be punctured, or can be punctured. When the 100MHz channel actually occupied by the first PPDU is punctured, 20MHz in the 100MHz can be punctured, or 40MHz in the 100MHz can be punctured. Therefore, the following describes the implementation of the 100MHz channel actually occupied by the first PPDU for the following three scenarios: the 100MHz actually occupied by the first PPDU does not exist puncturing, 20MHz in the 100MHz actually occupied by the first PPDU is punctured, and 40MHz in the 100MHz actually occupied by the first PPDU is punctured:

[0394] Scenario 2.11: The 100MHz actually occupied by the first PPDU does not exist puncturing.

[0395] In the scenario, the 100MHz actually occupied by the first PPDU does not exist puncturing, indicating that the 100MHz actually occupied by the first PPDU can be used for data transmission.

[0396] In this scenario, the implementation of the 100MHz channel actually occupied by the first PPDU can refer to the implementation of the 100MHz channel in scenario 1.11 of the communication method 100 described above, and will not be described again. For example, the 80MHz in the 100MHz actually occupied by the first PPDU can correspond to a 996-tone RU, and the highest 20MHz can correspond to a 242-tone RU, so that the channel for transmitting the first PPDU can include a 996+242-tone MRU.

[0397] It should be noted that the 996+242-tone MRU is not included in the 160MHz channel defined in the current protocol. That is, the 996+242-tone MRU format is a new MRU format defined by the embodiments of the present application.

[0398] Scenario 2.12: The 20MHz in the 100MHz actually occupied by the first PPDU is punctured.

[0399] Among them, the 20MHz in the 100MHz actually occupied by the first PPDU is punctured, indicating that there is 80MHz in the 100MHz actually occupied by the first PPDU that can be used to transmit data.

[0400] In this scenario, the puncturing field indication information of the first PPDU is also used to indicate that the 20MHz in the 100MHz is punctured, and the 20MHz is located in the lowest 80MHz in the 100MHz, or in other words, the punctured 20MHz is not the highest 20MHz in the 100MHz. Therefore, when the 20MHz in the 100MHz actually occupied by the first PPDU is punctured, the first to fourth 20MHz in the 100MHz can be punctured, and there are four puncturing modes.

[0401] In one possible implementation, the puncturing field indication information is a puncturing field, and the meaning of the puncturing field can refer to Table 7 described below:

[0402] Table 7

[0403] As can be seen from Table 7, when the value of the puncturing field is 0, it indicates that the highest 60MHz in the 160MHz is punctured, and there is no puncturing in the lowest 100MHz. When the value of the puncturing field is 1 to 4, it respectively indicates the puncturing of the 20MHz in the lowest 100MHz in the 160MHz when the highest 60MHz in the 160MHz is punctured. For example, when the value of the puncturing field is 2, it indicates that the highest 60MHz in the 160MHz is punctured, and the second 20MHz in the lowest 100MHz is punctured.

[0404] In addition, when the 20 MHz of the 100 MHz actually occupied by the first PPDU is punctured, the channel division manner of the actually occupied 100 MHz can refer to the channel division manner of the 100 MHz in scenario 1.12 of the communication method 100, or the channel division manner of the 100 MHz for transmitting the first PPDU can refer to the channel division manner of the 100 MHz in scenario 1.12 of the communication method 100, and details are not repeated herein.

[0405] For example, when the 20 MHz of the 100 MHz actually occupied by the first PPDU is punctured, the 100 MHz includes a 484+242+242-tone MRU. For another example, when the 20 MHz of the 100 MHz actually occupied by the first PPDU is punctured, the 100 MHz includes a 484+484-tone MRU. For another example, when the 20 MHz of the 100 MHz actually occupied by the first PPDU is punctured, the 100 MHz includes a 996-tone RU.

[0406] Scenario 2.13: 40 MHz of the 100 MHz actually occupied by the first PPDU is punctured.

[0407] In the scenario, the puncturing field of the first PPDU indicates that 40 MHz of the 100 MHz is punctured, and the 40 MHz is located in the lowest 80 MHz of the 100 MHz, or the punctured 40 MHz does not include the highest 20 MHz of the 100 MHz. Therefore, when 40 MHz of the 100 MHz is punctured, 40 MHz of the first to fourth 20 MHz of the 100 MHz can be punctured, and there are three puncturing modes, and the specific puncturing mode can refer to Table 7 shown in the above. For example, when the value of the puncturing field is 5, it indicates that the highest 60 MHz of the 160 MHz is punctured, and the lowest 40 MHz of the lowest 100 MHz of the 160 MHz is punctured.

[0408] In the scenario, the puncturing field of the first PPDU indicates that 40 MHz of the 100 MHz is punctured, and the 40 MHz is located in the lowest 80 MHz of the 100 MHz, or the punctured 40 MHz does not include the highest 20 MHz of the 100 MHz. Therefore, when 40 MHz of the 100 MHz is punctured, 40 MHz of the first to fourth 20 MHz of the 100 MHz can be punctured, and there are three puncturing modes, and the specific puncturing mode can refer to Table 7 shown in the above. For example, when the value of the puncturing field is 5, it indicates that the highest 60 MHz of the 160 MHz is punctured, and the lowest 40 MHz of the lowest 100 MHz of the 160 MHz is punctured.

[0409] In addition, when the 40 MHz of the 100 MHz actually occupied by the first PPDU is punctured, the channel division manner of the actually occupied 100 MHz can refer to the channel division manner of the 100 MHz in scenario 1.13 of the communication method 100, or the channel division manner of the 100 MHz for transmitting the first PPDU can refer to the channel division manner of the 100 MHz in scenario 1.13 of the communication method 100, and details are not repeated herein.

[0410] For example, the 100MHz channel can include a 484+242-tone MRU when 40MHz of the 100MHz actually occupied by the first PPDU is punctured. For another example, the 100MHz channel can include a 242+242+242-tone MRU when 40MHz of the 100MHz actually occupied by the first PPDU is punctured.

[0411] Transmission mode 2.2: OFDMA transmission.

[0412] In the OFDMA transmission mode, the first device can directly use the defined RU or MRU type without defining a new RU or MRU type, so as to reduce the implementation complexity. In a possible implementation, the first device can also redefine the RU or MRU type, so as to more flexibly utilize the resource and schedule users.

[0413] Similar to the non-OFDMA transmission, for the OFDMA transmission, the channel division of the 100MHz actually occupied by the first PPDU is described for the following three scenarios: there is no puncture in the 100MHz actually occupied by the first PPDU, 20MHz of the 100MHz actually occupied by the first PPDU is punctured, and 40MHz of the 100MHz actually occupied by the first PPDU is punctured:

[0414] Scenario 2.21: There is no puncture in the 100MHz actually occupied by the first PPDU.

[0415] When there is no puncture in the 100MHz actually occupied by the first PPDU, the first device can redefine a new RU or MRU or not redefine a new RU or MRU. In this mode, the channel division of the 100MHz actually occupied by the first PPDU can refer to the channel division of the 100MHz in scenario 1.21 of the communication method 100, which will not be described herein again.

[0416] For example, the 100 MHz channel actually occupied by the first PPDU without the puncturing includes one 484+242-tone MRU and two 242-tone RUs. For another example, the 100 MHz channel actually occupied by the first PPDU without the puncturing includes one 484-tone RU and three 242-tone RUs. For another example, the 100 MHz channel actually occupied by the first PPDU without the puncturing includes five 242-tone RUs. For another example, the 100 MHz channel actually occupied by the first PPDU without the puncturing can include one 242-tone RU and two 484-tone RUs.

[0417] Scenario 2.22: 20 MHz in the 100 MHz actually occupied by the first PPDU is punctured.

[0418] In this scenario, the puncturing field indication information is further used to indicate that 20 MHz in the 100 MHz is punctured, and the 20 MHz is located in the lowest 80 MHz in the 100 MHz. The meaning indicated by the puncturing field indication information and the puncturing mode can be referred to the description in scenario 1.12, and will not be described herein.

[0419] However, the specific form of the puncturing field indication information in this way is different from the specific form of the puncturing field indication information in scenario 1.12. For OFDMA transmission, the lowest 80 MHz in the 160 MHz corresponds to one 4-bit puncturing indication, the highest 80 MHz corresponds to one 4-bit puncturing indication, and the 4-bit of the highest 80 MHz is 1000. Among them, the 4-bit of the lowest 80 MHz in the 160 MHz is used to indicate the puncturing of 20 MHz in the lowest 80 MHz, and the 1000 of the highest 80 MHz is used to indicate that the highest 60 MHz in the highest 80 MHz is punctured and the lowest 20 MHz is not punctured. That is to say, for OFDMA transmission, for the first PPDU of the 160 MHz, there are two 4-bit puncturing indication information, one 4-bit puncturing indication information corresponds to the lowest 80 MHz in the 160 MHz, and is used to indicate the puncturing of 20 MHz in the lowest 80 MHz; the other bit is set to 1000, and is used to indicate that the highest 60 MHz in the highest 80 MHz in the 160 MHz is punctured and the lowest 20 MHz is not punctured.

[0420] For OFDMA transmission, the meaning of the puncturing field of the puncturing field indication information of the first PPDU can be referred to Table 8 shown below:

[0421] Table 8

[0422] In Table 8, the domain value -1 is a 4-bit corresponding to the lowest 80MHz in the 160MHz, and the domain value -2 is a 4-bit corresponding to the highest 80MHz in the 160MHz. The value of the domain value -1 represents the puncturing mode of the 20MHz in the lowest 80MHz in the 160MHz, for example, the value of the domain value -1 is set as 0111, indicating that the lowest 20MHz in the lowest 80MHz is punctured. The value of the domain value -2 is set as 1000, representing that the highest 60MHz in the 160MHz is punctured and the lowest 20MHz is not punctured, so as to guarantee that the actual occupied bandwidth of the first PPDU is 100MHz.

[0423] In addition, when the 20MHz in the 100MHz actually occupied by the first PPDU is punctured, the channel division mode of the 100MHz actually occupied by the first PPDU can refer to the channel division mode of the 100MHz in the scenario 1.22 in the communication method 100, which will not be described again. For example, when the 20MHz in the 100MHz actually occupied by the first PPDU is punctured, the 100MHz channel includes a 484+242+242-tone MRU. For another example, when the 20MHz in the 100MHz actually occupied by the first PPDU is punctured, the 100MHz channel includes a 484+484-tone MRU, and the two 484 subcarriers in the 484+484-tone MRU are continuous or discontinuous. For another example, when the 20MHz in the 100MHz actually occupied by the first PPDU is punctured, the 100MHz channel includes a 996-tone RU, and the 996 subcarriers in the 996-tone RU are continuous or discontinuous.

[0424] Scenario 2.23: 40MHz in the 100MHz actually occupied by the first PPDU is punctured.

[0425] In this scenario, the puncturing field indication information is also used to indicate that the 40MHz in the 100MHz actually occupied by the first PPDU is punctured, and the 40MHz is located in the lowest 80MHz in the 100MHz. The meaning indicated by the puncturing field indication information and the puncturing mode can refer to the description in the scenario 1.23 described above, and will not be described again.

[0426] However, the specific form of the puncturing field indication information in this mode is different from that in scenario 1.13. For OFDMA transmission, the lowest 80 MHz of the 160 MHz of the first PPDU corresponds to a 4-bit puncturing indication, the highest 60 MHz of the 160 MHz corresponds to a 4-bit puncturing indication, and the 4-bit of the highest 60 MHz is 1000. Among them, the 4-bit of the lowest 80 MHz of the 160 MHz is used to indicate the puncturing situation of the 40 MHz in the lowest 80 MHz, and the 1000 of the highest 80 MHz is used to indicate that the highest 60 MHz of the highest 80 MHz is punctured and the lowest 20 MHz is not punctured. That is, for OFDMA transmission, for the 160 MHz first PPDU, there are two 4-bit puncturing indication information, one 4-bit puncturing indication information corresponds to the lowest 80 MHz of the 160 MHz, and is used to indicate the puncturing situation of the 40 MHz in the lowest 80 MHz; the other bit is set to 1000, which is used to indicate that the highest 60 MHz of the highest 80 MHz of the 160 MHz is punctured and the lowest 20 MHz is not punctured.

[0427] In OFDMA transmission, when the puncturing field indication information is the puncturing field, the meaning of the puncturing field indicating that the 40 MHz of the 100 MHz actually occupied by the first PPDU is punctured can be referred to the above Table 8, and will not be repeated.

[0428] In addition, when the 40 MHz of the 100 MHz actually occupied by the first PPDU is punctured, the channel division mode of the 100 MHz can refer to the channel division mode of the 100 MHz in the above scenario 1.13. For example, when the 40 MHz of the 100 MHz actually occupied by the first PPDU is punctured, the 100 MHz channel includes 484+242-tone MRU. For another example, when the 40 MHz of the 100 MHz actually occupied by the first PPDU is punctured, the 100 MHz channel includes 242+242+242-tone MRU.

[0429] In addition, for OFDMA transmission, if the first PPDU includes a UHR-SIG field, there are RU Allocation fields in the common part of the UHR-SIG field for RU or MRU allocation of users, and for indicating the number of users corresponding to the allocated RU or MRU. Thus, for the first PPDU of 160MHz, there is one RU Allocation field in each 20MHz of the 160MHz, and there are a total of 8 RU Allocation fields (marked as RU Allocation #1 to RU Allocation #8 from low to high in frequency). Further, two content channels (CC) are usually defined, different contents are carried in different 20MHz subchannels to improve transmission efficiency.

[0430] For OFDMA transmission of the first PPDU of 160MHz, or Non-OFDMA MU-MIMO transmission, each CC carries in one 20MHz. In the lowest 80MHz of 160MHz, the repetition mode of CC1, CC2, CC1, CC2; in the highest 80MHz of 160MHz, there is CC1, and the content can be different from the content of CC1 in the highest 80MHz, so it can also be marked as CC3.

[0431] That is, the 100MHz channel used to transmit the first PPDU in 160MHz includes the first content channel and the second content channel in the low 80MHz, and the third content channel in the high 20MHz. In one possible implementation, the first PPDU includes a UHR-SIG, and the UHR-SIG includes the first content channel and the second content channel in the low 80MHz, and the third content channel in the high 20MHz.

[0432] In an optional implementation, the first content channel, the second content channel and the third content channel respectively carry four resource unit allocation fields. Among the four resource unit allocation fields carried by the first content channel and the third content channel respectively, three resource unit allocation fields are used to indicate RU or MRU allocation, and one resource unit allocation field is a reserved field or is used to indicate puncturing information or is used to indicate reserved information; among the four resource unit allocation fields carried by the second content channel, two resource unit allocation fields are used to indicate RU or MRU allocation, and two resource unit allocation fields are reserved fields or are used to indicate puncturing information or are used to indicate reserved information.

[0433] In one possible implementation, the first content channel and the third content channel each carries three resource unit allocation fields and one reserved field, and the second content channel carries two resource unit allocation fields and two reserved fields, each resource unit allocation field is used to indicate the allocation of RUs or MRUs.

[0434] For example, the first content channel is CC1, the second content channel is CC2, and the third content channel is CC3, wherein CC1 and CC2 are CCs included in the low 80 MHz of the 100 MHz channel actually occupied by the first PPDU, and CC3 is the CC included in the high 20 MHz of the 100 MHz channel actually occupied by the first PPDU. FIG. 48 is another schematic diagram of resource unit allocation information. As shown in FIG. 48, CC1 carries RU Allocation#1, RU Allocation#3, RU Allocation#5, and RU Allocation#7, CC2 carries RU Allocation#2, RU Allocation#4, RU Allocation#6, and RU Allocation#8, and CC3 carries RU Allocation#1, RU Allocation#3, RU Allocation#5, and RU Allocation#7. Among them, RU Allocation#1, RU Allocation#3, and RU Allocation#5 carried by CC1 and CC3 are used to indicate the allocation of RUs or MRUs, RU Allocation#7 carried by CC1 and CC3 is used to indicate puncturing information, or is used to indicate reserved information, or CC1 and CC3 do not carry RU Allocation#7, but carry a reserved field. RU Allocation#2 and RU Allocation#4 carried by CC2 are used to indicate the allocation of RUs or MRUs, and RU Allocation#6 and RU Allocation#8 carried by CC2 are used to indicate puncturing information, or are used to indicate reserved information, or CC2 does not carry RU Allocation#6 and RU Allocation#8, but carries two reserved fields.

[0435] In a possible implementation, the common field of the first content channel is located in a first common encoding block, the common field of the second content channel is located in a second common encoding block, and the common field of the third content channel is located in a third common encoding block. The first common encoding block, the second common encoding block, and the third common encoding block respectively carry four resource unit allocation fields. Alternatively, in the case that the first content channel, the second content channel, and the third content channel respectively carry four resource unit allocation fields, the common field of the first content channel, the common field of the second content channel, and the common field of the third content channel are respectively located in one common encoding block.

[0436] For example, FIGS. 49 to 51 are schematic diagrams of resource unit allocation information. As shown in FIG. 49, the common fields corresponding to RU Allocation#1, RU Allocation#3, RU Allocation#5, and RU Allocation#7 carried by CC1 are located in common encoding block 11. As shown in FIG. 50, the common fields corresponding to RU Allocation#2, RU Allocation#4, RU Allocation#6, and RU Allocation#8 carried by CC2 are located in common encoding block 21. As shown in FIG. 51, the common fields corresponding to RU Allocation#1, RU Allocation#3, RU Allocation#5, and RU Allocation#7 carried by CC3 are located in common encoding block 31.

[0437] In a possible implementation, the common field of the first content channel is located in a first common encoding block and a second common encoding block, the common field of the second content channel is located in a third common encoding block and a fourth common encoding block, and the common field of the third content channel is located in a fifth common encoding block and a sixth common encoding block. The first common encoding block to the sixth common encoding block respectively carry two resource unit allocation fields. Alternatively, in the case that the first content channel, the second content channel, and the third content channel respectively carry four resource unit allocation fields, the common field of the first content channel, the common field of the second content channel, and the common field of the third content channel are respectively located in two common encoding blocks.

[0438] For example, FIG. 52 to FIG. 54 are schematic diagrams of resource unit allocation information. As shown in FIG. 52, the common fields corresponding to RU Allocation#1 and RU Allocation#3 on CC1 are located in common encoding block 11, and the common fields corresponding to RU Allocation#5 and RU Allocation#7 are located in common encoding block 12. As shown in FIG. 53, the common fields corresponding to RU Allocation#2 and RU Allocation#4 on CC2 are located in common encoding block 21, and the common fields corresponding to RU Allocation#6 and RU Allocation#8 are located in common encoding block 22. As shown in FIG. 54, the common fields corresponding to RU Allocation#1 and RU Allocation#3 on CC3 are located in common encoding block 31, and the common fields corresponding to RU Allocation#5 and RU Allocation#7 are located in common encoding block 32.

[0439] It can be seen that when the first content channel, the second content channel and the third content channel respectively carry four resource unit allocation fields, the common fields of the first content channel, the common fields of the second content channel and the common fields of the third content channel are respectively located in one common encoding block, or the common fields of the first content channel, the common fields of the second content channel and the common fields of the third content channel are respectively located in two common encoding blocks.

[0440] S202. The first device transmits a first PPDU by using a 100MHz channel remaining after the highest 60MHz of the 160MHz is punctured.

[0441] S203. The second device receives the first PPDU.

[0442] S204. The second device parses the first PPDU.

[0443] The second device parses the first PPDU, including: reading the bandwidth field indication information and the puncturing field indication information of the first PPDU, obtaining that the bandwidth of the first PPDU is 160MHz through the bandwidth field indication information, and obtaining that the highest 60MHz of the 160MHz is punctured through the puncturing field indication information, so as to determine that the actual occupied bandwidth of the first PPDU is 100Mz.

[0444] In a possible implementation, the second device further obtains the puncturing condition of the 100MHz actually occupied by the first PPDU by reading the puncturing field indication information, so as to obtain the channel carrying the data information according to the puncturing condition of the 100MHz actually occupied by the first PPDU, and then obtain the data information carried in the channel. In a possible implementation, the second device reads the puncturing field in the U-SIG of the first PPDU, and obtains the puncturing condition of the 100MHz channel actually occupied by the first PPDU through the puncturing field, so as to obtain the data information from the channel that is not punctured.

[0445] In an implementation of the transmission, the 100MHz used by the first device to transmit the first PPDU belongs to the 5735MHz to 5835MHz of the unlicensed frequency band. In this way, the first device can fully use the 100MHz corresponding to the 5735MHz to 5835MHz of the unlicensed frequency band to transmit data, that is, the frequency spectrum utilization of 5.8GHz can be maximized, the frequency spectrum utilization and system throughput are improved, and the time delay is reduced.

[0446] In addition, the spectrum of the UNII-2A part of the unlicensed frequency band needs to be matched with dynamic frequency selection (DFS) and transmit power control (TPC) to detect signals such as weather radars, which is relatively complex and is prone to false alarms, so it is relatively difficult to use a spectrum greater than 80MHz at 5.1GHz. When the 100MHz used by the first device to transmit the first PPDU belongs to the 5735MHz to 5835MHz of the unlicensed frequency band, the use of the 100MHz channel is added in the UNII-3 part, and the use of the spectrum greater than 80MHz can be more easily realized.

[0447] In a possible implementation, the 100MHz used by the first device to transmit the first PPDU belongs to the licensed frequency band. In this way, when there is a 100MHz relatively available bandwidth in some environment, the first device can fully use the 100MHz to transmit data, and the frequency spectrum utilization can be improved.

[0448] In a possible implementation, when the first device sends the first PPDU with an actual bandwidth of 100MHz to the second device, the first device can also send a PPDU with an actual bandwidth of 160MHz to the second device, so as to maximize the frequency spectrum utilization of 5GHz in combination with multi-link transmission (MLO).

[0449] It can be seen that, in the embodiment of the application, the bandwidth field in the first PPDU generated by the first device indicates that the bandwidth of the first PPDU is 160 MHz, and the puncturing field indicates that the highest 60 MHz in the 160 MHz is punctured, so the actual bandwidth occupied by the first PPDU is 100 MHz, and therefore the first device transmits the first PPDU by using the 100 MHz channel remaining after puncturing the highest 60 MHz in the 160 MHz, and 100 MHz data transmission can be implemented. Compared with the first device transmitting information by using the PPDU defined in the protocol, the method can improve the spectrum utilization.

[0450] The embodiment of the application provides a communication method 300, and FIG. 55 is an interaction schematic diagram of the communication method 300. The communication method 300 is also described from the perspective of the interaction between the first device and the second device. The communication method 300 includes but is not limited to the following steps:

[0451] S301. The first device generates an aggregated PPDU, the bandwidth of the aggregated PPDU is 100 MHz, and the aggregated PPDU is obtained by aggregation of a second PPDU and a third PPDU, the bandwidth of the second PPDU is 20 MHz, and the bandwidth of the third PPDU is 80 MHz.

[0452] In the embodiment of the application, the first device generates the aggregated PPDU, including: generating the second PPDU and the third PPDU; and generating the aggregated PPDU by using the second PPDU and the third PPDU.

[0453] In addition, the aggregated PPDU can be one PPDU, that is, the first device aggregates the second PPDU and the third PPDU to obtain one PPDU, and the PPDU is the aggregated PPDU. In a possible implementation, the aggregated PPDU is two separate PPDUs, that is, the first device aggregates the second PPDU and the third PPDU to obtain two PPDUs, for example, the aggregated PPDU includes the second PPDU and the third PPDU.

[0454] The bandwidth of the second PPDU is 20 MHz, and the bandwidth of the third PPDU is 80 MHz, so that the aggregated PPDU obtained by aggregation of the second PPDU and the third PPDU occupies 100 MHz bandwidth, thereby facilitating the first device to transmit the aggregated PPDU by using 100 MHz, implementing 100 MHz data transmission, and improving the spectrum utilization.

[0455] In a possible implementation, the 100 MHz of the transmission aggregated PPDU belongs to the 5735-5835 MHz of the unlicensed frequency band. In this way, the first device can fully utilize the 100 MHz corresponding to the 5735-5835 MHz of the unlicensed frequency band to transmit data, that is, the frequency spectrum utilization of 5.8 GHz can be maximized, the frequency spectrum utilization and system throughput are improved, and the time delay is reduced.

[0456] In a possible implementation, the 100 MHz of the transmission aggregated PPDU belongs to the licensed frequency band. In this way, when there is a 100 MHz of relatively available bandwidth in some environment, the first device can fully use the 100 MHz to transmit data, and the frequency spectrum utilization can be improved.

[0457] In a possible implementation, the second PPDU and the third PPDU are two PPDUs of the same protocol version. For example, the second PPDU and the third PPDU are both UHR PPDUs, that is, the aggregated PPDU can be obtained by aggregating two UHR PPDUs with bandwidths of 20 MHz and 80 MHz, so that the aggregated PPDU can also be regarded as a UHR PPDU. The UHR PPDU can be referred to as described in S101, and details are not described herein again. For example, FIG. 56 is a schematic diagram of an aggregated PPDU. As shown in FIG. 56, the aggregated PPDU is obtained by aggregating two UHR PPDUs with bandwidths of 20 MHz and 80 MHz.

[0458] In a possible implementation, the second PPDU and the third PPDU are two PPDUs of different protocol versions. For example, the second PPDU is a UHR PPDU, and the third PPDU is an HE PPDU, that is, the aggregated PPDU can be obtained by aggregating a UHR PPDU with a bandwidth of 20 MHz and an HE PPDU with a bandwidth of 80 MHz. For example, FIG. 57 is a schematic diagram of another aggregated PPDU. As shown in FIG. 57, the aggregated PPDU is obtained by aggregating a UHR PPDU with a bandwidth of 20 MHz and an HE PPDU with an aggregated bandwidth of 80 MHz.

[0459] For another example, the second PPDU is an HE PPDU, and the third PPDU is a UHR PPDU, that is, the PPDU can be obtained by aggregating a UHR PPDU with a bandwidth of 80 MHz and an HE PPDU with a bandwidth of 20 MHz.

[0460] For another example, the second PPDU is a UHR PPDU, and the third PPDU is an EHT PPDU, i.e., the aggregated PPDU can be obtained by aggregating a UHR PPDU with a bandwidth of 20 MHz and an EHT PPDU with a bandwidth of 80 MHz. For example, FIG. 58 is a schematic diagram of another aggregated PPDU, as shown in FIG. 58, the aggregated PPDU is obtained by aggregating a UHR PPDU with a bandwidth of 20 MHz and an EHT PPDU with an aggregated bandwidth of 80 MHz.

[0461] For another example, the second PPDU is a UHR PPDU, and the third PPDU is an EHT PPDU, i.e., the aggregated PPDU can be obtained by aggregating a UHR PPDU with a bandwidth of 20 MHz and an EHT PPDU with a bandwidth of 80 MHz. For example, FIG. 58 is a schematic diagram of another aggregated PPDU, as shown in FIG. 58, the aggregated PPDU is obtained by aggregating a UHR PPDU with a bandwidth of 20 MHz and an EHT PPDU with an aggregated bandwidth of 80 MHz.

[0462] It can be seen that the aggregated PPDU can be obtained by aggregating a HE PPDU and a UHR PPDU, or the aggregated PPDU can be obtained by aggregating an EHT PPDU and a UHR PPDU. In this case, the transmission of traditional users (i.e., users before the UHR standard) and UHR users can be supported in parallel, and the throughput of the traditional users can be maximized.

[0463] In a possible implementation, the UHR PPDU described above can also be replaced by a UHR+ PPDU, and the UHR+ PPDU represents a PPDU after 802.11bn. In addition, the naming of the UHR+ PPDU is not limited in the embodiments of the present application.

[0464] S302. The first device transmits the aggregated PPDU by using 100 MHz.

[0465] It can be understood that when the aggregated PPDU is two separate PPDUs, the first device transmits the aggregated PPDU by using 100 MHz can mean that the first device transmits the two separate PPDUs in the aggregated PPDU by using 100 MHz and in time alignment.

[0466] S303. The second device receives the aggregated PPDU.

[0467] S304. The second device parses the aggregated PPDU.

[0468] In the step S304, the second device parses the aggregated PPDU, including: the second device reads the aggregated PPDU to obtain data information.

[0469] It can be seen that, in the embodiment of the application, the first device can generate an aggregated PPDU by aggregation of the second PPDU and the third PPDU, and the aggregated PPDU occupies a bandwidth of 100 MHz, so that the first device transmits the aggregated PPDU to the second device by using a 100 MHz channel, 100 MHz data transmission can be achieved, and the spectrum utilization can be improved.

[0470] The scheme in the embodiment of the application can be implemented by a private scheme or by a manufacturer-specific feature in addition to the standard definition, that is, the scheme is used for communication between devices under the same company or the same alliance. Before the devices transmit the 100 MHz PPDU, the devices negotiate to use the scheme of the embodiment of the application.

[0471] On the basis of the scheme in the embodiment of the application, the first PPDU can further carry manufacturer identification information, which is used to indicate which manufacturer the PPDU comes from, and the PPDU can further indicate that the private scheme technology of the embodiment of the application is used by the indication of the embodiment of the application.
