[0001] The present application claims priority from the Chinese patent application No. 202410455289.X filed on April 15, 2024, and entitled "Information transmission method and transmission apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] Embodiments of the present application relate to the field of communication, in particular to an information transmission method and transmission apparatus in the field of communication. BACKGROUND

[0003] In a wireless local area network (WLAN) communication process, a station usually transmits a physical layer protocol data unit (PPDU) based on a trigger of a trigger frame. Illustratively, an access point transmits a trigger frame to a station, and the trigger frame includes information for indicating resource units; the station determines the allocated resource units based on the trigger frame, and transmits the PPDU. The trigger frame includes multiple user information fields, and for different stations, the access point can indicate the allocated resource units to each station through the user information field matched with each station.

[0004] However, such an information transmission method can cause a large signaling overhead of the trigger frame. SUMMARY

[0005] The present application provides an information transmission method and transmission apparatus, which can help to reduce the signaling overhead of the trigger frame.

[0006] In a first aspect, an information transmission method is provided, the method comprising: receiving a trigger frame, the trigger frame including first information and second information, the first information being used to indicate a first continuous resource unit (RU), and the second information being used to indicate that the RUs in a first frequency domain range are continuous RUs, and / or the RUs in a second frequency domain range are discrete RUs and the discrete bandwidth of the discrete RUs in the second frequency domain range; wherein the second information is carried in a common field and / or a special user information field; and transmitting data on the first RU, the first RU being determined according to the first information and the second information.

[0007] In a possible implementation, the method is performed by a first device or a chip in the first device.

[0008] The information transmission method of the present application can help reduce the signaling overhead of the trigger frame by carrying the second information in the common field and / or the special user information field in the trigger frame, so that the multiple first devices can read the second information and determine the resource units allocated to each first device based on the second information.

[0009] In addition, by carrying the second information in the common field and / or the special user information field in the trigger frame, the second information read by the multiple first devices is the same, which helps reduce the conflict of the resource units allocated to the multiple first devices by the second device.

[0010] For example, the multiple first devices are all in one frequency domain range, and the multiple first devices can determine whether the resource units in the frequency domain range are discrete resource units or continuous resource units through the second information, and in the case of determining that the resource units in the frequency domain range are discrete resource units, the discrete bandwidth of the discrete resource units in the frequency domain range can also be determined.

[0011] However, if different user information fields are used to indicate resource units for different first devices, for multiple first devices in the same frequency domain range, part of the first devices may determine that the resource units in the frequency domain range are discrete resource units, and another part of the first devices may determine that the resource units in the frequency domain range are continuous resource units, thereby causing the resource units corresponding to the multiple first devices in the frequency domain range to conflict. Or, for multiple first devices in the same frequency domain range, part of the first devices may be indicated that the discrete bandwidth of the discrete resource units in the frequency domain range is bandwidth 1, and another part of the first devices may be indicated that the discrete bandwidth of the discrete resource in the frequency domain range is bandwidth 2, and the frequency domain positions of bandwidth 1 and bandwidth 2 also have an intersection, so that the discrete distribution mode of the discrete units corresponding to the frequency domain range conflicts.

[0012] In combination with the first aspect, in some implementations of the first aspect, the second information includes first sub-information and / or second sub-information, the first sub-information is used to indicate that the RUs in the first frequency domain range are continuous RUs, and the second sub-information is used to indicate that the RUs in the second frequency domain range are discrete RUs and indicate the discrete bandwidth of the discrete RUs in the second frequency domain range.

[0013] In this way, different sub-information can be used to indicate that the RUs in the first frequency domain range are continuous RUs and the discrete bandwidth of the discrete RUs in the second frequency domain range, respectively.

[0014] In some implementations of the first aspect, the second sub-information satisfies one or more of the following conditions: the second sub-information is used to indicate that the discrete bandwidth of the discrete RU in the second frequency domain range includes a first discrete bandwidth and a second discrete bandwidth, the second frequency domain range includes a first sub-frequency domain range and a second sub-frequency domain range, the discrete bandwidth of the discrete RU in the first sub-frequency domain range is the first discrete bandwidth, and the discrete bandwidth of the discrete RU in the second sub-frequency domain range is the second discrete bandwidth; the second sub-information is used to indicate that the discrete bandwidth of the discrete RU in the second frequency domain range includes a third discrete bandwidth, and the discrete bandwidth of the discrete RU in the second frequency domain range is the third discrete bandwidth; or, the second sub-information is used to indicate that the discrete bandwidth of the discrete RU in the second frequency domain range includes a fourth discrete bandwidth, the second frequency domain range includes i third sub-frequency domain ranges, the discrete bandwidth of the discrete RU in each of the i third sub-frequency domain ranges is the fourth discrete bandwidth, and i is a positive integer.

[0015] In this way, the second sub-information can indicate the discrete bandwidth of the discrete RU in the second frequency domain range in different forms.

[0016] In some implementations of the first aspect, the second sub-information satisfies the following conditions: in a case where the bandwidth corresponding to the first contiguous RU is greater than 20 MHz, the discrete bandwidth of the discrete RU in the second frequency domain range indicated by the second sub-information is c times the bandwidth corresponding to the first contiguous RU, and c is an even number greater than or equal to 2; and / or, in a case where the bandwidth corresponding to the first contiguous RU is less than or equal to 20 MHz, the discrete bandwidth of the discrete RU in the second frequency domain range indicated by the second sub-information is greater than or equal to 20 MHz.

[0017] In a case where the bandwidth corresponding to the first contiguous RU is greater than 20 MHz, the discrete bandwidth corresponding to the first contiguous RU usually needs to be greater than the bandwidth corresponding to the first contiguous RU. Therefore, in this way, the invalid indication of the second sub-information can be reduced. For example, the first contiguous RU is a 996-tone RU. If the discrete bandwidth indicated by the second sub-information includes 40 MHz, the information in the second sub-information used to indicate that the discrete bandwidth is 40 MHz is invalid indication.

[0018] In some implementations of the first aspect, the first frequency domain range and / or the second frequency domain range, and the first sub-information and / or the second sub-information satisfy any one of the following conditions: if the bandwidth of the data unit is greater than or equal to the first bandwidth, the first bandwidth includes the first frequency domain range and / or the second frequency domain range, the first frequency domain range and / or the second frequency domain range include X frequency domain ranges, each of the X frequency domain ranges is a first value, the first value is a ratio of the first bandwidth to X, X is an integer greater than or equal to 1, each of the X sub-information included in the first sub-information and / or the second sub-information is M bits, M is a positive integer, and the X frequency domain ranges correspond to the X sub-information one by one; if the bandwidth of the data unit is 1 / a of the first bandwidth, each of the X sub-information is M bits, each of the X frequency domain ranges is a product of the first value and 1 / a, a is a positive integer greater than or equal to a first threshold and less than or equal to a second threshold; if the bandwidth of the data unit is 1 / b of the first bandwidth, the first bandwidth includes c frequency domain ranges, each of the c frequency domain ranges is 20 MHz, the first sub-information and / or the second sub-information includes c sub-information, the c sub-information corresponds to the c frequency domain ranges one by one, each of the c sub-information is X*M / c bits, b is a positive integer greater than or equal to a third threshold, the third threshold is greater than the second threshold, and c is a ratio of the bandwidth of the data unit to 20 MHz; or, if the bandwidth of the data unit is equal to Y frequency domain ranges, the first frequency domain range and / or the second frequency domain range includes Y frequency domain ranges, the first sub-information and / or the second sub-information includes Y sub-information, the Y sub-information corresponds to the Y frequency domain ranges one by one, each of the Y sub-information is M bits, each of the Y frequency domain ranges is the first value, and Y is a positive integer less than X.

[0019] In this way, the number of bits corresponding to each sub-information and / or each frequency domain range can correspondingly change as the bandwidth of the data unit changes. This makes the indication manner of the first sub-information and the second sub-information more flexible.

[0020] In some implementations of the first aspect, the second information includes information for indicating that the RU in the second frequency domain range is a discrete RU and information for indicating a discrete bandwidth of the discrete RU in the second frequency domain range.

[0021] In this way, the second information can respectively indicate that the RU in the second frequency domain range is a discrete RU and the discrete bandwidth of the discrete RU in the second frequency domain range through different information.

[0022] In some embodiments of the first aspect, the second information comprises information indicating that the RUs in the first frequency domain range are contiguous RUs, and information indicating the puncturing status of N1 sub-channels included in the first frequency domain range, N1 being a positive integer; and / or the second information comprises information indicating that the RUs in the second frequency domain range are discrete RUs, and information indicating the puncturing status of N2 sub-channels included in the second frequency domain range, N2 being a positive integer.

[0023] In this way, the second information can indicate whether the RUs in each frequency domain range are discrete RUs and the discrete bandwidth of the discrete RUs in the second frequency domain range respectively through different information.

[0024] In some embodiments of the first aspect, each of the second frequency domain ranges comprises 4 sub-channels, and the second sub-information satisfies one or more of the following conditions: if the 4 sub-channels are not punctured, the discrete bandwidth of the discrete RUs in each of the frequency domain ranges is the total bandwidth covered by the 4 sub-channels; if the 4 sub-channels include 3 adjacent sub-channels that are not punctured and one punctured sub-channel, the discrete bandwidth of the discrete RUs in each of the frequency domain ranges includes a fifth discrete bandwidth and a sixth discrete bandwidth, the fifth discrete bandwidth is the bandwidth covered by one of the 3 adjacent sub-channels adjacent to the punctured sub-channel, and the sixth discrete bandwidth is the bandwidth covered by the remaining two of the 3 adjacent sub-channels; if the 4 sub-channels include one punctured sub-channel, one sub-channel that is not punctured on one side of the punctured sub-channel, and two sub-channels that are not punctured on the other side of the punctured sub-channel, the discrete bandwidth of the discrete RUs in each of the frequency domain ranges includes the bandwidth covered by the one sub-channel that is not punctured, and the bandwidth covered by the two sub-channels that are not punctured; if the 4 sub-channels include two adjacent punctured sub-channels and two adjacent sub-channels that are not punctured, the discrete bandwidth of the discrete RUs in each of the frequency domain ranges includes the bandwidth covered by the two adjacent sub-channels that are not punctured; if the 4 sub-channels include two non-adjacent sub-channels that are not punctured, the discrete bandwidth of the discrete RUs in each of the frequency domain ranges includes a seventh discrete bandwidth and an eighth discrete bandwidth, the seventh discrete bandwidth is the bandwidth covered by one of the two sub-channels that are not punctured, and the eighth discrete bandwidth is the bandwidth covered by the other of the two sub-channels that are not punctured; and / or if the 4 sub-channels include one sub-channel that is not punctured, the discrete bandwidth of the discrete RUs in each of the frequency domain ranges includes the bandwidth covered by the one sub-channel that is not punctured.

[0025] In this way, for different puncturing statuses indicated by the second information, different discrete bandwidths can be corresponded, so that the first device can determine the discrete bandwidth corresponding to each frequency domain range based on the puncturing status of the plurality of sub-channels included in each frequency domain range.

[0026] With reference to the first aspect, in some implementations of the first aspect, the trigger frame further includes third information, the third information being used to indicate whether the discrete RU in the second frequency range includes a ninth discrete bandwidth, the ninth discrete bandwidth being S times of the bandwidth of each of the frequency ranges in the second frequency range, S being an integer greater than 1; or, the information used to indicate that the RU in the second frequency range is the discrete RU is further used to indicate that the discrete bandwidth of the discrete RU in the second frequency range is the ninth discrete bandwidth.

[0027] In this way, the second device can indicate the discrete bandwidths of more than one frequency range through the trigger frame. The first device can determine whether the discrete bandwidth corresponding to each frequency range is the ninth discrete bandwidth based on the third information or the information used to indicate that the RU in the second frequency range is the discrete RU.

[0028] With reference to the first aspect, in some implementations of the first aspect, the discrete bandwidth corresponding to the first contiguous RU is the smaller one of the bandwidth of the data unit and the discrete bandwidth of the discrete RU in the second frequency range.

[0029] It can be understood that, in the case where the discrete bandwidth of the discrete RU in the second frequency range is equal to the bandwidth of one frequency range, if the bandwidth of the data unit is smaller than one frequency range, the discrete bandwidth corresponding to the first contiguous RU will not be one frequency range, but the bandwidth of the data unit; if the bandwidth of the data unit is greater than or equal to one frequency range, the discrete bandwidth corresponding to the first contiguous RU is equal to the bandwidth of one frequency range.

[0030] With reference to the first aspect, in some implementations of the first aspect, the first RU is determined according to the first information and the second information includes: the first RU is the first contiguous RU; or, the first RU is a discrete RU obtained by mapping the first contiguous RU on the discrete bandwidth corresponding to the first contiguous RU, the discrete bandwidth corresponding to the first contiguous RU being determined based on the first contiguous RU and the discrete bandwidth of the discrete RU in the second frequency range.

[0031] In this way, the first device can determine the RU used to transmit the data unit based on the first information and the second information.

[0032] With reference to the first aspect, in some implementations of the first aspect, the second information is used to indicate that: the RU in the first frequency range is the contiguous RU, and the RU in the second frequency range is the discrete RU and the discrete bandwidth of the discrete RU in the second frequency range, the first frequency range and the second frequency range being different frequency ranges.

[0033] In this way, the first frequency domain range and the second frequency domain range do not have intersection, which helps to reduce the conflict of the subcarrier distribution mode of the first frequency domain range and the second frequency domain range. For example, if the first frequency domain range and the second frequency domain range have intersection, for the frequency domain range of the intersection, the RU in the frequency domain range of the intersection cannot be both discrete RU and continuous RU, which will cause conflict.

[0034] In a second aspect, another information transmission method is provided. The method comprises: sending a trigger frame, the trigger frame comprising first information and second information, the first information being used to indicate a first continuous resource unit (RU), and the second information being used to indicate that the RU in a first frequency domain range is a continuous RU, and / or the RU in a second frequency domain range is a discrete RU and the discrete bandwidth of the discrete RU in the second frequency domain range; wherein the second information is carried in a common field and / or a special user information field; and receiving data, the data being sent on the first RU, the first RU being determined according to the first information and the second information.

[0035] In a possible implementation, the method can be performed by the second device, or by a chip in the second device.

[0089] The technical solutions in the present application will be described below with reference to the drawings.

[0090] In the embodiments of the present application, the same items or similar items with substantially the same functions and effects are distinguished by using "first", "second", and the like. For example, the first value and the second value are merely used to distinguish different values, and the order is not limited. Those skilled in the art can understand that "first", "second", and the like do not limit the quantity and execution order, and "first", "second", and the like do not necessarily mean different.

[0091] It should be noted that in the embodiments of the present application, "exemplarily" or "for example" and the like are used to represent as an example, illustration or description. Any embodiment or design scheme described as "exemplarily" or "for example" in the present application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. Rather, the use of "exemplarily" or "for example" and the like is intended to present the relevant concept in a specific manner.

[0092] In the embodiments of the present application, "at least one" means one or more, and "multiple" means two or more. "And / or" describes the association relationship of the associated objects, which means that there can be three kinds of relationships, for example, A and / or B, which can represent the following three cases: A exists alone, A and B exist together, and B exists alone, where A and B can be singular or plural. The character "or" generally represents that the associated objects before and after have an "or" relationship. "At least one of the following" or the like means any combination of these items, including any combination of single item or multiple items. For example, at least one of a, b, or c can represent a, b, c, a-b, a-c, b-c, or a-b-c, where a, b, and c can be single or multiple.

[0093] In order to facilitate understanding of the method provided by the embodiments of the present application, the system architecture of the method provided by the embodiments of the present application will be described below. It can be understood that the system architecture described in the embodiments of the present application is used to more clearly illustrate the technical solutions of the embodiments of the present application, and does not constitute a limitation on the technical solutions provided by the embodiments of the present application.

[0094] The technical solutions provided in the application can be applied to a wireless local area network (WLAN) scenario. Exemplarily, the technical solutions can be applied to IEEE 802.11 system standards, for example, 802.11a / b / g standards, 802.11n standards, 802.11ac standards, 802.11ax standards, or next-generation standards such as 802.11be, Wi-Fi 7 standards, or more next-generation standards such as Wi-Fi 8, 802.11bn standards. The technical solutions provided in the embodiments of the application can also be applied to a wireless personal area network system based on ultra wide band (UWB), such as 802.15 series standards; can also be applied to a sensing system, such as 802.11bf series standards; can also be applied to an IEEE integrated millimeter wave (IMMW) protocol; and can also be applied to a spark link / nearlink standard protocol.

[0095] For a throughput rate, the 802.11n standard can be referred to as high throughput (HT), the 802.11ac standard can be referred to as very high throughput (VHT), the 802.11ax (Wi-Fi 6) can be referred to as high efficient (HE), the 802.11be (Wi-Fi 7) can be referred to as extremely high throughput (EHT), and the 802.11bn can be referred to as ultra high reliability (UHR). For standards before HT, for example, 802.11a / b / g, and the like, they can be collectively referred to as non-high throughput (Non-HT).

[0096] For bandwidth (BW) configuration, the 802.11ax standard supports the following bandwidth configurations: 20 MHz, 40 MHz, 80 MHz, 160 MHz, and 80+80 MHz. Among them, the difference between 160 MHz and 80+80 MHz is that 160 MHz is a continuous frequency band, and the two 80 MHz of 80+80 MHz can be separated. In the 802.11be standard, in addition to the above bandwidth configurations, 320 MHz is also supported. The maximum bandwidth supported by the new 802.11bn standard is also at least 320 MHz.

[0097] Although the embodiments of the present application are mainly described by taking the deployment of WLAN network, especially the network applying IEEE 802.11 system standard as an example, it is easy for those skilled in the art to understand that various aspects involved in the present application can be extended to other networks applying various standards or protocols, for example, BLUETOOTH, high performance radio LAN (HIPERLAN) (a wireless standard similar to IEEE 802.11 standard, mainly used in Europe) and wide area network (WAN), personal area network (PAN) or other now known or later developed networks. Therefore, various aspects provided by the present application can be applied to any suitable wireless network regardless of the coverage range and wireless access protocol used.

[0098] The embodiments of the present application can also be applicable to wireless local area network systems such as internet of things (IoT) network or vehicle to X (V2X). Of course, the embodiments of the present application can also be applicable to other possible communication systems, for example, long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD), universal mobile telecommunication system (UMTS), worldwide interoperability for microwave access (WiMAX) communication system, 5th generation (5G) communication system, and future 6th generation (6G) communication system, etc.

[0099] The above-mentioned communication systems applying the present application are only illustrative, and the communication systems applying the present application are not limited thereto, which are uniformly described herein and will not be described below.

[0100] The above briefly describes the system architecture of the embodiments of the present application, in order to better understand the technical solutions of the embodiments of the present application, the following will introduce several contents related to the embodiments of the present application.

[0101] 1、Access Point (AP)

[0102] Also can be called as the station of the access point class. The access point can be a device with wireless transceiver function, and can provide services for the station. The access point is the access point of the mobile user into the wired network, and can be deployed indoors or outdoors. For example, the access point is mainly deployed indoors of the family, the building and the park. The access point is equivalent to a bridge connecting the wired network and the wireless network, and the main function is to connect various stations together, and then access the wireless network into the wired network.

[0103] Optionally, the access point can be a terminal device or a network device with a wireless fidelity (Wi-Fi) chip, for example, the access point can be a communication server, a router, a switch or a network bridge, etc.

[0104] It should be understood that the access point can also be called as a wireless access access point or a hotspot, etc., which is not specifically limited in the present application.

[0105] 2, Station (STA)

[0106] It can be a device with wireless transceiver function, which can access the wireless local area network based on the access point. The station can be a wireless communication chip, a wireless sensor or a wireless communication terminal. For example, the station can be a mobile phone supporting Wi-Fi communication function, a tablet computer supporting Wi-Fi communication function, a set top box supporting Wi-Fi communication function, a smart television supporting Wi-Fi communication function, a smart wearable device supporting Wi-Fi communication function, a vehicle-mounted communication device supporting Wi-Fi communication function and a computer supporting Wi-Fi communication function, etc.

[0110] The terminal device can be a device that provides voice / data connectivity to a user, for example, a handheld device with wireless connection function, a vehicle-mounted device, etc. At present, some examples of terminal devices include: a mobile phone, a tablet computer, a notebook computer, a palm computer, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical surgery, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a 5G network, or a terminal device in a future evolved public land mobile network (PLMN), etc., which are not limited in the present application.

[0111] By way of example and without limitation, in this application, a terminal device can be a terminal device in an internet of things (IoT) system. The internet of things is an important component of future information technology development, and its main technical feature is to connect objects through communication technology and network, so as to realize the intelligent network of man-machine interconnection and object-object interconnection. Illustratively, the terminal device in the embodiments of the present application can be a wearable device. The wearable device can also be referred to as a wearable smart device, which is a general term for smart devices that can be worn, such as glasses, gloves, watches, clothing, and shoes, which are designed and developed by applying wearable technology to daily wear. The wearable device is a portable device that can be directly worn on the body or integrated into the user's clothes or accessories. The wearable device is not only a hardware device, but also can realize powerful functions through software support and data interaction, cloud interaction. The general wearable smart device includes a full function, large size, and can realize complete or partial functions without relying on a smart phone, such as a smart watch or smart glasses, and only focuses on a certain application function, and needs to cooperate with other devices such as a smart phone, such as various smart wristbands, smart jewelry, and other devices for monitoring vital signs.

[0112] By way of example and without limitation, in the embodiments of the present application, the terminal device can also be a terminal device in machine type communication (MTC). In addition, the terminal device can also be a vehicle-mounted module, a vehicle-mounted module, a vehicle-mounted component, a vehicle-mounted chip, or a vehicle-mounted unit, etc. built-in as one or more components or units in a vehicle. The vehicle can implement the method provided in the present application by built-in vehicle-mounted module, vehicle-mounted module, vehicle-mounted component, vehicle-mounted chip or vehicle-mounted unit, etc. Therefore, the embodiments of the present application can also be applied to the Internet of Vehicles, such as vehicle to everything (V2X), long term evolution-vehicle (LTE-V), vehicle-to-vehicle (V2V) technology, etc.

[0113] The network device involved in the present application can be a device in communication with a terminal device, which can also be referred to as an access network device or a radio access network device, which can be a transmission reception point (TRP), an evolved NodeB (eNB or eNodeB) in an LTE system, a home evolved NodeB (home NodeB, HNB), a baseband unit (BBU), a wireless controller in a cloud radio access network (CRAN) scenario, or a relay station, an access point, a vehicle-mounted device, a wearable device, a network device in a 5G network or a future evolved PLMN network, an access point (AP) in a WLAN, a gNB in an NR system, a city base station, a micro base station, a pico base station, a femto base station, and the like, which are not limited in the present application.

[0114] 4. Low power indoor (LPI)

[0115] is a communication mode defined by regulations related to the 6 GHz spectrum, in which the maximum power and maximum power spectral density of the transmitting end are limited. For example, for an access point (AP), the maximum power is 30 dBm (decibel-milliwatts), and the maximum power spectral density is 5 dBm / MHz (decibel-milliwatts / megahertz); for a station (STA), the maximum power is 24 dBm, and the maximum power spectral density is -1 dBm / MHz. The power of the transmitting end is limited by both the maximum power and the maximum power spectral density, that is, the transmission power cannot exceed the maximum power value, and the power spectral density of the transmission cannot exceed the maximum power spectral density. The maximum power spectral density can also be understood as the maximum power that can be transmitted per MHz.

[0116] Compared with the maximum power, the maximum power spectral density is more restrictive, that is, the maximum power allowed to be transmitted is usually more limited by the power spectral density. In this way, under the condition that the power spectral density of the transmitting end does not exceed the maximum power spectral density, the transmission power of the transmitting end is usually difficult to reach the maximum power.

[0117] With the increase of the sending bandwidth, the maximum sending power of the sending end also increases accordingly, that is, with the different bandwidth configurations, the maximum power sent by the sending end is different. As shown in Table 1, when the bandwidth is 320MHz, the maximum power limit of the access point and the station specified by the regulation is reached. Below this bandwidth, only lower power can be sent due to the maximum power spectral density limit.

[0118] Table 1

[0119] 5、Preamble puncture

[0120] It is a transmission method proposed in the 802.11ax standard to solve the problem that some channels cannot transmit information for a period of time or at a specific time. Through this method, the sending end can still transmit a physical layer protocol data unit (PPDU) in the case that part of the subchannels are in a busy state.

[0121] Exemplarily, as shown in FIG. 1, on an 80MHz frequency spectrum, in order of frequency from low to high, there are channel 1, channel 2, channel 3 and channel 4. Among them, channel 2 can be a punctured subchannel. Channel 1, channel 3 and channel 4 can also be used to transmit information.

[0122] 6、Bandwidth capability limited station

[0123] It can be understood that different stations support different maximum bandwidth capabilities, especially in the 5GHz and 6GHz frequency spectrum. Some stations only support 20MHz bandwidth, which are called 20MHz only STA (stations that only support 20MHz bandwidth). Some stations support a maximum bandwidth of 80MHz, which are called 80MHz only STA (stations that only support 80MHz bandwidth). In addition to supporting the maximum bandwidth, 80MHz only STA also supports relatively small bandwidths such as 20MHz and 40MHz. Some stations support a maximum bandwidth of 160MHz, which are called 160MHz only STA.

[0124] The station that supports a bandwidth smaller than the PPDU bandwidth is a bandwidth capability limited station. Exemplarily, when the PPDU bandwidth is 80MHz, the 80MHz only STA is a station that supports the full bandwidth, and therefore the 80MHz only STA is not a bandwidth capability limited station; the 20MHz only STA is not a station that supports the full bandwidth, and therefore the 20MHz only STA is a bandwidth capability limited station.

[0125] 7. Extreme high throughput physical layer protocol data unit (EHT PPDU) formats

[0126] Two EHT PPDU formats are defined in the 802.11be standard, i.e., an extreme high throughput multiple user physical layer protocol data unit (EHT MU PPDU) format and an extreme high throughput trigger based physical layer protocol data unit (EHT TB PPDU) format.

[0127] The EHT MU PPDU can support single user (down-link (DL) or up-link (UL)) and multi-user (DL) data transmission.

[0128] The EHT MU PPDU format can be as shown in Table 2. That is, the EHT MU PPDU includes the following fields: a legacy short training field (L-STF), a legacy long training field (L-LTF), a legacy signal field A (L-SIG), a repeated L-SIG (RL-SIG), a universal SIG (U-SIG), an extremely high throughput signal field (EHT-SIG), an extremely high throughput short training field (EHT-STF), an extremely high throughput long training field (EHT-LTF), data (DATA), and a packet extension (PE).

[0129] Table 2

[0130] The meanings of the fields included in the EHT MU PPDU can be as shown in Table 3.

[0131] Table 3

[0132] The EHT TB PPDU format can be as shown in Table 4. That is, the EHT TB PPDU includes the following fields: L-STF, L-LTF, L-SIG, RL-SIG, U-SIG, EHT-STF, EHT-LTF, data, and PE.

[0133] Table 4

[0134] The EHT TB PPDU is a data unit sent by one or more stations triggered by trigger frames (TFs) sent by an access point. Exemplarily, as shown in FIG. 2, the access point 1 sends a trigger frame to the station 1, the station 2, and the station 3. In response to the trigger frame, the station 1, the station 2, and the station 3 send EHT TB PPDUs to the access point 1. In response to the EHT TB PPDUs sent by the station 1, the station 2, and the station 3, the access point 1 sends an acknowledgement frame to the station 1, the station 2, and the station 3.

[0135] The frame structure of the trigger frame can be as shown in FIG. 3. The trigger frame includes a common information field and a user information list field. The user information list field includes one or more user information fields. For example, the user information list field in FIG. 3 includes a user information 1 field and a user information 2 field, and the like.

[0136] The common information field can be understood as a common field, that is, a field that needs to be read by multiple users. The user information 1 field in the user information list field is different from the user information 2 field to the user information E field, that is, the user information 1 is a special user information field. Similar to the common information field, the information included in the user information 1 field is a field that needs to be read by multiple users. Each user can determine that the field needs to be read by the association identifier in the user information 1 field.

[0137] The user information fields of the user information 2 field to the user information E field are fields matched with respective users. The association identifier included in each of the user information 2 field to the user information E field can be a different association identifier, and the association identifier included in each of the user information 2 field to the user information E field is respectively associated with a respective user. In this way, in a case where one of the user information 2 field to the user information E field is an identifier associated with the apparatus, a user can read the one user information field by determining the one user information field through the association identifier. Exemplarily, if the station F receives the trigger frame, and it is parsed that the association identifier of the user information F exists in the user information 2 to the user information E and matches the station F, the station F reads the user information field of the user information F. E is an integer greater than or equal to 2, and F is an integer less than or equal to E.

[0138] The public information field can include trigger type, UL length, more TF, carrier sense (CS), UL bandwidth, guard interval (GI) + long training field (LTF) type, multi-user multiple-input multiple-output (MU-MIMO) LTF type, number of LTF symbols and midamble periodicity, UL space-time block-coded (UL STBC), low density parity check code (LDPC) extra symbol segment, access point transmit (TX) power, pre-forward error correction (pre-FEC) padding factor, packet extension disambigulty (PE disambigulty), UL spatial reuse, doppler, UL high efficient signal A2 (HE-SIG-A2) reserved, reserved, and trigger dependent common info. The UL HE-SIG-A2 reserved can include HE / EHT indication, special user field present indication, and other UL HE-SIG-A2 reserved.

[0139] It can be understood that the special user field present indication can be used to indicate whether the special user information field exists in the user information list field. If the special user field present indication indicates that the special user information field exists in the user information list field, each station can determine that the user information 1 is the special user information field, and each station reads the information included in the user information 1.

[0140] The user info 1 field can also be referred to as a special user info field. The special user info field can include an application identification 12 (AID 12), a PHY version ID, an uplink EHT bandwidth extension (UL EHT BW extension), an uplink EHT spatial reuse 1, an uplink EHT spatial reuse 2, a general signaling field disregard and validate indication (U-SIG disregard and validate), a reservation, and trigger dependent user info.

[0141] The user info 2 to user info E can also be referred to as EHT variant user info fields. The EHT variant user info fields include an application identification 12 (AID 12), an RU allocation, an uplink FEC coding type, an uplink EHT modulation and coding scheme (UL EHT-MCS), a reservation, a spatial stream start value, a spatial stream number, an uplink target received signal strength indication (UL target RSSI), a primary secondary 160 (PS160), and trigger dependent user info.

[0142] It should be noted that the special user info field is not limited to only including the user info 1 field, and the EHT variant user info field is not limited to including the user info 2 field to the user info E field. In some possible implementation manners, the special user info field included in the user info list field can be more, for example, the special user info field can also include a user info 2 field, a user info 5 field, or a user info 7 field, and the like. Correspondingly, the number of user info fields included in the EHT variant user info field can be less. Alternatively, the user info 1 field can also belong to the EHT variant user info field, one or several of the user info 2 to user info E fields belong to the special user info field, and the like. The present application does not make a specific limitation on the fields included in the special user info field and the fields included in the EHT variant user info field.

[0143] It should be noted that the special user information field is not determined by the name of the user information field. The special user information field can be determined by a special association identifier in the special user information field, so that each station can read the information carried in the special user information field. Alternatively, the special association identifier in the special user information field can be, for example, "=2007". In this way, each station will read the information in the special user information field after identifying "=2007".

[0144] It should be understood that in the embodiments of the present application, the EHT variant user information field can also be replaced by other names, which are not limited in the embodiments of the present application.

[0145] In order to facilitate the understanding of the embodiments of the present application, first, the communication system suitable for the embodiments of the present application will be described in detail in combination with FIG. 4.

[0146] FIG. 4 is a schematic diagram of a communication system 400 applied in the embodiments of the present application. The communication system 400 can include at least one access point, such as the access point 410 and the access point 420 shown in FIG. 4; the communication system 400 can also include at least one station, such as the station 430, the station 440 and the station 450 shown in FIG. 4.

[0147] Among them, each access point in the communication system can be associated with one or more stations, and the access point can schedule radio resources such as frequency domain resources for the associated one or more stations. For example, the access point 410 is associated with the station 430 and the station 440. The access point 410 can schedule radio resources for the station 430 and the station 440, so that the station 430 and the station 440 can transmit uplink data and downlink data using the radio resources. In addition, the access point can also schedule radio resources for stations not associated with it. For example, the access point 410 can also schedule radio resources for the station 450, etc. The present application does not make specific limitation.

[0148] It can be understood that the access point scheduling radio resources for the station can include, for example, the access point indicating resource units to the station through a trigger frame, so that the station can transmit a PPDU using the resource units.

[0149] It should be understood that the association of the access point with the station can be understood as the service of the access point to the station, etc., which can also be called the access of the station to the access point, etc., which is not limited in the present application.

[0150] Devices in a communication system can communicate over wireless links. For example, access points in a communication system can communicate with each other, e.g., access point 410 can communicate with access point 420; stations in a communication system can communicate with each other, e.g., station 440 can communicate with station 450; or, access points and stations in a communication system can communicate with each other, e.g., station 410 can communicate with station 430 and station 440, etc.

[0151] It is noted that FIG. 4 shows two access points and three stations by way of example. Alternatively, the communication system 400 can include more or fewer access points and / or more or fewer stations, which embodiments are not limited to.

[0152] Each of the above communication devices, e.g., an access point or a station in FIG. 4, can be configured with multiple antennas. The multiple antennas can include at least one transmit antenna for transmitting signals and at least one receive antenna for receiving signals. In addition, each of the communication devices can additionally include a transmitter chain and a receiver chain, which can each include multiple components (e.g., a processor, a modulator, a multiplexer, a demodulator, a demultiplexer, or an antenna, etc.) related to signal transmission and reception.

[0153] It is also understood that the methods provided by embodiments of the present application can be applicable to various communication systems including a 5G new radio (NR) system, and the communication system 400 is merely an example. Embodiments of the present application are not limited to a specific architecture of a system to which they are applied, nor to a specific number and configuration of devices included in the various communication systems.

[0154] Next, a description is provided of a manner in which an access point currently indicates resource units to a station by means of a trigger frame.

[0155] It is understood that a resource unit includes multiple tones, e.g., a 26-tone RU including 26 tones, a 52-tone RU including 52 tones, or a 242-tone RU including 242 tones, etc. Therefore, for ease of understanding, a description is first provided of tone plans for various bandwidths.

[0156] In combination with FIG. 5, when the bandwidth is 20MHz, the entire bandwidth can be composed of one entire 242-tone RU, or various combinations of 26-tone RU, 52-tone RU or 106-tone RU. For example, 20MHz can be composed of 9 26-tone RUs, one of which can be composed of two RUs including 13 subcarriers. Alternatively, it can be composed of 2 106-tone RUs. Alternatively, it can also be composed of two 52-tone RUs and one 106-tone RU, etc. In this way, 20MHz can have multiple combinations. For the sake of brevity, they are not shown one by one here.

[0157] In addition to the above RUs for transmitting data, the bandwidth of 20MHz also includes some guard subcarriers, null subcarriers or direct current (DC) subcarriers.

[0158] In combination with FIG. 6, when the bandwidth is 40MHz, the entire bandwidth is roughly equivalent to the subcarrier distribution of two 20MHz. The entire bandwidth can be composed of one entire 484-tone RU, or various combinations of 26-tone RU, 52-tone RU, 106-tone RU or 242-tone RU.

[0159] In combination with FIG. 7, when the bandwidth is 80MHz, the entire bandwidth is composed of 4 242-tone RUs as a unit, and the entire bandwidth can also be composed of one entire 996-tone RU. Alternatively, the entire bandwidth can also be composed of various combinations of 26-tone RU, 52-tone RU, 106-tone RU, 242-tone RU, 484-tone RU. Among them, 484L and 484R respectively represent the left half and the right half of the 484-tone RU, and 484L and 484R respectively contain 242 subcarriers, which can also be understood as another illustration of 484+5DC.

[0160] It should be understood that, in the embodiments of the present application, for each subcarrier distribution shown in FIG. 5 to FIG. 7, each RU can be arranged in order of frequency from low to high in sequence from left to right. For example, in combination with FIG. 7, when the bandwidth is 80MHz, the entire bandwidth can also be composed of 8 106-tone RUs, which can be arranged in order of frequency from low to high in sequence from left to right, i.e., the 106-tone RU 701 is the 106-tone RU at the lowest position in the frequency domain, and the 106-tone RU 702 is the 106-tone RU at the highest position in the frequency domain. For the sake of brevity, this will not be described again hereinafter.

[0161] In addition, for the sake of description, for each subcarrier distribution shown in FIG. 5 to FIG. 7, each RU can be sequentially referred to as the first RU, the second RU, etc. in sequence from low to high in frequency. For example, in combination with FIG. 7, the 106-tone RU 701 is the 106-tone RU at the lowest position in the frequency domain, which can be referred to as the first 106-tone RU, and the 106-tone RU 702 can be referred to as the eighth 106-tone RU, and so on.

[0162] By analogy, when the bandwidth is 160MHz, it can be understood that the entire bandwidth is composed of two 80MHz subcarrier distributions. The entire bandwidth can be composed of a whole 2x996-tone RU, or various combinations of 26-tone RUs, 52-tone RUs, 106-tone RUs, 242-tone RUs, 484-tone RUs or 996-tone RUs. When the bandwidth is 320MHz, it can be understood that the entire bandwidth is composed of four 80MHz subcarrier distributions.

[0163] It should be understood that when the bandwidth is greater than or equal to 40MHz, the combination of RUs included in the entire bandwidth is similar to that of the 20MHz bandwidth, and the description above can be referred to, which will not be described again hereinafter.

[0164] It should be noted that, in addition to the RUs shown above, the RUs in the embodiments of the present application can also be multi-RUs (MRUs) composed of different RUs. For example, a 52-tone RU and a 26-tone RU compose a 52+26-tone RU; a 106-tone RU and a 26-tone RU compose a 106+26-tone RU; a 484-tone RU and a 242-tone RU compose a 484+242-tone RU; a 996-tone RU and a 484-tone RU compose a 996+484-tone RU; a 242-tone RU, a 484-tone RU and a 996-tone RU compose a 242+484+996-tone RU; two 996-tone RUs and a 484-tone RU compose a 2x996+484-tone RU; three 996-tone RUs compose a 3x996-tone RU; three 996-tone RUs and a 484-tone RU compose a 3x996+484-tone RU, and the like. The present application does not make a specific limitation on this.

[0165] It should be understood that the embodiments of the present application are described by taking the RUs as examples, and in some possible implementation manners, part or all of the RUs in the embodiments of the present application can also be replaced by MRUs, and the present application does not make a specific limitation on this.

[0166] It should also be noted that the 20MHz, 40MHz, 80MHz, 160MHz or 320MHz bandwidth can sequentially include 1, 2, 4, 8 or 16 20MHz respectively. Among them, the 20MHz can be understood as a subchannel (subchannel) defined in the 802.11 system standard. Therefore, the 20MHz, 40MHz, 80MHz, 160MHz or 320MHz bandwidth can sequentially include 1, 2, 4, 8 or 16 subchannels respectively. In combination with the subcarrier distribution of the 20MHz, 40MHz, 80MHz, 160MHz or 320MHz bandwidth above, the 20MHz, 40MHz, 80MHz, 160MHz or 320MHz bandwidth can also be understood as being composed of one or more 242-tone RUs. When the entire bandwidth is greater than 20MHz, according to the frequency from low to high, the multiple 242-tone RUs can sequentially correspond to the following identifiers respectively: 1 st , 2 nd , …. For example, when the bandwidth is 320MHz, 16 242-tone RUs can sequentially correspond to: 1 st , 2 nd , …, 16th .

[0167] In addition, in combination with FIG. 8, in order to reduce interference between channels, the frequency ranges of the two sub-channels constituting a 40MHz channel do not overlap each other in 5GHz or 6GHz. That is, the first and second 20MHz constitute a first 40MHz, and the frequency ranges of the first and second 20MHz do not overlap; the third and fourth 20MHz constitute a second 40MHz, and the frequency ranges of the third and fourth 20MHz do not overlap. And, the second 20MHz and the third 20MHz cannot constitute a 40MHz channel. Similarly, the frequency ranges of the two 40MHz channels constituting an 80MHz do not overlap each other; the frequency ranges of the two 80MHz channels constituting a 160MHz do not overlap each other.

[0168] However, since 320MHz is relatively scarce, the first 160MHz and the second 160MHz can constitute a 320MHz-1 channel. At the same time, the second 160MHz and the third 160MHz can constitute a 320MHz-2 channel.

[0169] It should be understood that the RUs shown in the above can be understood as regular RUs (rRUs) or contiguous RUs. And the subcarrier distribution modes shown in the above can be understood as regular subcarrier distribution modes or contiguous subcarrier distribution modes.

[0170] In combination with the regular subcarrier distribution modes of various bandwidths in the above, the access point can indicate the RUs to be used by each station to send an EHT TB PPDU through a user information field in the trigger frame, such as user information 2 field to user information E field. For example, in combination with FIG. 7, the access point indicates a second 52-tone RU to a station through user information 2 in the trigger frame, and the station can send an EHT TB PPDU through the second 52-tone RU.

[0171] However, in the indoor low-power consumption scenario, since the maximum power spectral density of the transmitting end is limited, that is, the spectral density needs to be less than the maximum power spectral density when the station sends an EHT TB PPDU, the power of the station sending the EHT TB PPDU is usually small, that is, it is difficult to reach the maximum power of the station.

[0172] In order to increase the power of the station sending the EHT TB PPDU, at present, the subcarriers included in each bandwidth can be distributed in a discrete manner. This discrete distribution manner can also be referred to as a uniform allocation method. The RU composed of the subcarriers distributed in a discrete manner can be referred to as a distribution RU (dRU). The discrete frequency domain range of the distribution RU can be referred to as a distribution BW (DBW), that is, the RU is distributed in a discrete manner in the frequency domain range of the distribution BW.

[0173] Taking a bandwidth of 20 MHz as an example, the discrete distribution manner of the subcarriers included in the 20 MHz can be as shown in Table 5. The 20 MHz can be composed of 9 26-tone RUs, and each of the 9 26-tone RUs is distributed on the 20 MHz in a discrete manner, so that the 20 MHz is the distribution BW of the 9 26-tone RUs.

[0174] In the table, the value in the column corresponding to the subcarrier (tone) can be understood as the number of the subcarrier; and the value in the column corresponding to the RU can be understood as the RU number of the 26-tone RU. Starting from the subcarrier number -121, the 9 26-tone RUs with the RU numbers 1 to 9 are arranged in a cyclic manner in the order of 5, 1, 6, 3, 8, 2, 7, 4, and 9.

[0175] It should be understood that the 9 26-tone RUs included in the 20 MHz are arranged in a cyclic manner in the order of 5, 1, 6, 3, 8, 2, 7, 4, and 9 in the RU number only as an example. In some possible implementation manners, the RU numbers of the 9 26-tone RUs can also be arranged in a cyclic manner in other orders, for example, the 9 26-tone RUs included in the 20 MHz can be arranged in a cyclic manner in the order of 1, 6, 3, 8, 2, 7, 4, 9, and 5 in the RU number, and the like, which are not limited in the embodiments of the present application.

[0176] It should be understood that Table 5 is only an example, and the RU numbers of the 20 MHz can also be other numbers, and / or the 9 26-tone RUs in the 20 MHz can also be distributed in other discrete distribution manners. For example, the 9 26-tone RUs with the RU numbers 1 to 9 can also not be arranged in a cyclic manner, that is, can be arranged in a random distribution manner, and the like. The present application does not make a specific limitation in this regard.

[0177] Table 5

[0178] As can be seen from Table 5, each of the 9 26-tone RUs includes 26 subcarriers that are discretely distributed in the whole 20MHz. For example, for the 26-tone RU with RU number 1, it includes the subcarrier with subcarrier number -120, the subcarrier with subcarrier number -111, the subcarrier with subcarrier number -102, the subcarrier with subcarrier number -30, the subcarrier with subcarrier number -21, the subcarrier with subcarrier number -12, the subcarrier with subcarrier number 6, the subcarrier with subcarrier number 15, and so on. Different from the 26-tone RU that is an rRU, the 26-tone RU with RU number 1 includes multiple subcarriers that are not multiple consecutive subcarriers.

[0179] It should be noted that since the 106-tone RU is composed of 4 26-tone RUs and 2 extra subcarriers, Table 1 also includes 2 106-1 and 2 106-2. For example, 106-1 can be understood as the extra subcarriers of the dRU corresponding to the rRU on the lower frequency side or left side, and 106-2 can be understood as the extra subcarriers of the dRU corresponding to the rRU on the higher frequency side or right side.

[0180] It should be understood that in the case of a bandwidth greater than 20MHz, the discrete distribution of subcarriers is similar to Table 5, which is not shown one by one here.

[0181] For the RU indicated by the access point to the station through the trigger frame, if the RU is an rRU, the spectral density of the station sending the EHT TB PPDU on the rRU is less than or equal to the maximum power spectral density of the station. Since both the 802.11be standard and the 802.11bn standard configure the subcarrier spacing to be 78.125KHz, 1MHz / 0.078125MHz = 12.8, so the frequency range of 1MHz can include 13 subcarrier positions specified in the standard. Assuming that the maximum power spectral density of the station is P dBm / MHz. Then the transmission power of each subcarrier in each MHz in the RU of the station is less than or equal to P / 13dBm.

[0182] However, if the RU indicated by the access point to the station through the trigger frame is a dRU, i.e., the RU is discrete on a larger bandwidth. For example, the RU is discrete on Q MHz, Q MHz includes a plurality of 26-tone RUs discrete on Q MHz. So that each 26-tone RU of the plurality of 26-tone RUs includes 26 subcarriers distributed on Q MHz. In this way, assuming that the maximum power spectral density of the station is P dBm / MHz, the transmission power of the station on Q MHz is less than or equal to P x Q dBm. Since each 26-tone RU of the plurality of 26-tone RUs includes 26 subcarriers distributed on Q MHz, each 26-tone RU includes 26 subcarriers less than or equal to P x Q dBm. Then the transmission power of the station on each subcarrier is less than or equal to P x Q / 26. Wherein, Q is greater than or equal to 20.

[0183] Therefore, since P x Q / 26 is greater than P / 13 dBm, by transmitting the EHT TB PPDU by using the dRU, the transmission power of the station can be larger, and as the discrete bandwidth Q increases, the transmission power of the station can be larger.

[0184] In combination with the 9 26-tone RUs with RU numbers 1 to 9 shown in Table 5. When the bandwidth is 20 MHz, the composition of the 26-tone RU, the 52-tone RU, the 106-tone RU or the 242-tone RU can be as shown in Table 6. Wherein, the 26-tone RU can be the 9 26-tone RUs with RU numbers 1 to 9. The 52-tone RU can be 52-tone RU 1, 52-tone RU 2, 52-tone RU 3 or 52-tone RU 4. The 52-tone RU 1 can be composed of two 26-tone RUs with RU numbers 1 and 2; the 52-tone RU 2 can be composed of two 26-tone RUs with RU numbers 3 and 4; the 52-tone RU 3 can be composed of two 26-tone RUs with RU numbers 6 and 7; the 52-tone RU 4 can be composed of two 26-tone RUs with RU numbers 8 and 9. The 106-tone RU can be 106-tone RU 1 or 106-tone RU 2. The 106-tone RU 1 can be composed of 52-tone RU 1 and 52-tone RU 2; the 106-tone RU 2 can be composed of 52-tone RU 3 and 52-tone RU 4.

[0185] It should be understood that, when the bandwidth is 20MHz, since the 20MHz can be composed of one 242-tone RU, the 242-tone RU cannot be discretely on the 20MHz. Therefore, when the RU size is 242-tone RU, the combination shown in Table 6 is not applicable (N / A).

[0186] Table 6

[0187] It should be noted that the RU size can be understood as the number of subcarriers included in the RU, such as 26-tone RU or 52-tone RU, etc. The RU size can be referred to as RU size, etc., which is not limited in the present application.

[0188] By analogy, when the bandwidth is 40MHz, the composition of the 26-tone RU, the 52-tone RU, the 106-tone RU or the 242-tone RU can be as shown in Table 7.

[0189] Table 7

[0190] In combination with the dRU in the above. The access point can indicate the dRU for the station in the following manner, so that the station can transmit the EHT TB PPDU by using the dRU.

[0191] It should be noted that the above lists the composition of various different sizes of RUs when the bandwidth is 20MHz and 40MHz. By analogy, when the bandwidth is 80MHz, 160MHz or 320MHz or other bandwidth, the composition of various different sizes of RUs included in each bandwidth is similar to the way shown in Table 6 and Table 7, that is, the larger size RU can be composed of the smaller size RU. For the sake of brevity, they will not be listed one by one here.

[0192] In order to indicate the allocated discrete RU to the stations, one possible way is that the AP indicates the dRU of each station to the station respectively through the user info 2 to user info E in the trigger frame. For example, the dRU of station 2 is indicated to station 2 through the user info 2; the dRU of station 3 is indicated to station 3 through the user info 3; the dRU of station 4 is indicated to station 4 through the user info 4; and so on. The way of indicating the dRU of each station to the station can be that the field of the user info corresponding to the station in the trigger frame carries the information 1, information 2 and information 3. The information 1 is used to indicate the rRU, for example, the size and the position of the rRU. The position of the rRU can be understood as the absolute position of the rRU in the normal subcarrier distribution mode of each bandwidth. For example, the absolute position of the rRU in FIG. 5, FIG. 6 or FIG. 7. The information 2 can be 1 bit, and can be used to indicate that the rRU indicated by the information 1 is a dRU, that is, the rRU indicated by the information 1 is in discrete distribution. The information 3 can be 2 bits or more bits, and is used to indicate the discrete bandwidth of the dRU, for example, 00 indicates 20MHz, 01 indicates 40MHz, and so on. The multiple RUs included in the discrete bandwidth of the dRU have a correlation with the RUs at the positions in the normal subcarrier distribution mode, for example, the first 26-tone RU in FIG. 5 can be associated with the 26-tone RU numbered 1 in Table 5. In this way, in the case that the position of the rRU is determined based on the information 1, and the rRU is determined to be a dRU based on the information 2, the station can determine the dRU to be used for transmitting the PPDU according to the discrete bandwidth of the dRU indicated by the information 3, the position of the rRU indicated by the information 1, and the correlation.

[0193] For example, in combination with FIG. 5, it is assumed that the rRU indicated by the information 1 is the second 26-tone RU in FIG. 5, the rRU is a dRU indicated by the information 2, and the discrete bandwidth is 20MHz indicated by the information 3. Since the distribution mode of the 26-tone RU corresponding to 20MHz is shown in Table 5, and the second 26-tone RU is associated with the 26-tone RU numbered 2 in Table 5. Therefore, the station can determine that the dRU to be used for transmitting the PPDU is the 26-tone RU numbered 2.

[0194] However, with the increase of the number of stations, the signaling overhead of the AP for indicating the RU of each station to the station through the trigger frame is large. Therefore, there is an urgent need for a method to reduce the signaling overhead of the trigger frame of the AP.

[0195] It can be found from the above manner of indicating the dRU of each station to each station that the multiple user information corresponding to the multiple stations includes redundant information indicating the dRU. For example, for a PPDU of 80MHz, if the user information field corresponding to station A indicates the first 26-tone RU in the 80MHz, the user information field of station B indicates the second 26-tone RU in the 80MHz. Then, for the information 1 indicating the position of the rRU, both the two 26-tone RUs are in one 20MHz of the 80MHz. If the discrete bandwidth of one of station A and station B is 40MHz, the discrete bandwidth of the other of station A and station B is usually also 40MHz. In this way, there is redundancy between the information 2 and the information 3 in the user information field corresponding to station A and station B.

[0196] It should be noted that in the above example, if the discrete bandwidths of station A and station B are different, not only the implementation is complex, but also resource allocation conflicts are easily caused. Therefore, the discrete bandwidths of station A and station B in one 20MHz are usually the same. In other words, there is usually no aliasing between the discrete bandwidths, that is, the same 20MHz does not belong to the discrete bandwidth A and also belong to the discrete bandwidth B different from the discrete bandwidth A, so the signaling overhead can be saved.

[0197] Therefore, the present application provides an information transmission method, by carrying the common part in the information indicating the dRU of multiple stations in a field in the trigger frame that can be read by the multiple stations, so that the access point does not need to indicate the common part in the user information field corresponding to each of the multiple stations, thereby helping to reduce the signaling overhead of the trigger frame.

[0198] The information transmission method of the present application will be described in detail below in combination with FIGS. 9-24. The embodiments shown in the present application show the information transmission method provided by the present application from the perspective of device interaction. The specific forms and quantities of the devices shown are only examples and should not constitute any limitation on the implementation of the method provided by the present application. In the following, the second device and the first device are taken as the execution subject to describe the information transmission method of the embodiments of the present application in detail.

[0199] It should be understood that the second device can be the second device itself, can be a chip, a chip system or a processor supporting the second device to implement the information transmission method, can also be a logic module or software capable of implementing all or part of the second device; the first device can be the first device itself, can be a chip, a chip system or a processor supporting the first device to implement the information transmission method, can also be a logic module or software capable of implementing all or part of the first device, which is not limited in the present application.

[0200] FIG. 9 is a flow diagram of an information transmission method 900 provided by an embodiment of the present application. The method 900 can be applied to the communication system 400. In the method 900, the first device can be a station, such as the station 430 and / or the station 440 in the communication system 400, and the second device can be an access point, such as the access point 410 in the communication system 400. The method 900 includes the following steps:

[0201] S901. The second device sends a trigger frame to the first device, the trigger frame including first information and second information, the first information being used to indicate a first contiguous RU, and the second information being used to indicate that the RUs in a first frequency domain range are contiguous RUs, and / or the RUs in a second frequency domain range are discrete RUs and the discrete bandwidth of the discrete RUs in the second frequency domain range; wherein the second information is carried in a common information field or a special user information field. Correspondingly, the first device receives the trigger frame from the second device.

[0202] The first information used to indicate the first contiguous RU can be understood as the first information being used to indicate the size and the frequency domain location of the first contiguous RU. In this way, the first device can determine the size and the absolute location in the regular subcarrier distribution of the first contiguous RU through the first information. For example, the first information is used to indicate that the size of the first contiguous RU is a 52-tone RU, and the first contiguous RU is the third 52-tone RU on a subcarrier distribution with a bandwidth of 80MHz, and the like.

[0203] It should be noted that the corresponding first contiguous RUs can be the same or different for different first devices. Therefore, the first information can be understood as information matched with each first device. For example, for the first device 1, the first information indicates the first contiguous RU 1, i.e., the size and the location of the first contiguous RU 1; for the first device 2, the first information indicates the first contiguous RU 2, i.e., the size and the location of the first contiguous RU 2.

[0204] It should also be noted that the first contiguous RU indicated by the first information can also be replaced by other RUs; the first contiguous RU is not necessarily the actual resource unit configured by the second device for the first device, and the first device also needs to determine the resource unit configured by the second device for the first device in combination with the second information.

[0205] Optionally, the first information is carried in a user information field in the trigger frame, i.e., a user information field, such as a user information 2 field to a user information E field, and the like. In this way, for different first devices, the user information field matched with the device can be determined through the associated identifier in the user information field, so that the first information matched with the device can be read.

[0206] Optionally, the first information can indicate the first contiguous RU in various forms. For example, the first information can be carried in one or more fields in the trigger frame, such as a resource unit allocation subfield, a PS 160 subfield, etc.

[0207] The second information can be understood as information that needs to be read by one or more first devices, i.e., general information that needs to be read by the first devices to obtain the allocated RU. Therefore, the second information is carried in a common information field or a special user information field. In this way, the first devices can read the second information from the common information field or the special user information field, and each of the first devices can determine the allocated RU in combination with the first information matched with the device.

[0208] It should also be understood that, in the embodiments of the present application, the information that does not need to be read can also be replaced by information that does not need to be read and does not affect the reception of the trigger frame, and the information that needs to be read can also be replaced by information that needs to be read and affects the reception of the trigger frame, which is not limited in the present application.

[0209] It should be noted that the second information is used to indicate that the RU in the second frequency domain range is a discrete RU, and the discrete bandwidth of the discrete RU in the second frequency domain range can also be replaced by: the second information is used to indicate the discrete bandwidth of the discrete RU in the second frequency domain range, i.e., in the case where the second information is used to indicate the discrete bandwidth of the discrete RU in the second frequency domain range, the first device can also determine or default that the RU in the second frequency domain range is a discrete RU.

[0210] It can be understood that the first frequency domain range can be one or more frequency domain ranges in the first bandwidth; the second frequency domain range can also be understood as one or more frequency domain ranges in the first bandwidth. That is, the first bandwidth includes the first frequency domain range and / or the second frequency domain range.

[0211] The first frequency domain range is less than or equal to the first bandwidth. For example, assuming that the first bandwidth is 320 MHz, the first frequency domain range can be 320 MHz, indicating that the RU in the 320 MHz is a contiguous RU; or the first bandwidth is 320 MHz, and the first frequency domain range can be 80 MHz, indicating that the RU in the 80 MHz is a contiguous RU.

[0212] The number of frequency domain ranges included in the first frequency domain range can be one or more, and the second information is used to indicate that the RUs in each of the one or more frequency domain ranges are contiguous RUs. When the number of frequency domain ranges included in the first frequency domain range is more than one, the plurality of frequency domain ranges can be the same or different. For example, the first frequency domain range includes frequency domain range 1 and frequency domain range 2, and both the frequency domain range 1 and the frequency domain range 2 are 80MHz. The second information can be used to indicate that the RUs in the frequency domain range 1 are contiguous RUs, and also used to indicate that the RUs in the frequency domain range 2 are contiguous RUs. Alternatively, the first frequency domain range includes frequency domain range 3 and frequency domain range 4, and the frequency domain range 3 is 80MHz and the frequency domain range 4 is 160MHz. The second information can be used to indicate that the RUs in the frequency domain range 3 are contiguous RUs, and also used to indicate that the RUs in the frequency domain range 4 are contiguous RUs.

[0213] The second frequency domain range is less than or equal to the first bandwidth. For example, assuming that the first bandwidth is 320MHz, the second frequency domain range can be 320MHz, indicating that the RUs in the 320MHz are discrete RUs; or the first bandwidth is 320MHz, and the second frequency domain range can be 160MHz, indicating that the RUs in the 160MHz are discrete RUs; or the first bandwidth is 320MHz, and the second frequency domain range can be 80MHz, indicating that the RUs in the 80MHz are discrete RUs, and so on.

[0214] The number of frequency domain ranges included in the second frequency domain range can be one or more, and the second information is used to indicate that the RUs in each of the one or more frequency domain ranges are discrete RUs, and indicate the discrete bandwidth of the discrete RUs in each of the one or more frequency domain ranges. When the number of frequency domain ranges included in the second frequency domain range is more than one, the plurality of frequency domain ranges can be the same or different. For example, the second frequency domain range includes frequency domain range 5 and frequency domain range 6, and both the frequency domain range 5 and the frequency domain range 6 are 80MHz. The second information can be used to indicate that the RUs in the frequency domain range 5 are discrete RUs, and indicate that the discrete bandwidth of the discrete RUs in the frequency domain range 5 is 40MHz; the second information is also used to indicate that the RUs in the frequency domain range 6 are discrete RUs, and indicate that the discrete bandwidth of the discrete RUs in the frequency domain range 6 is 20MHz. Alternatively, the first frequency domain range includes frequency domain range 7 and frequency domain range 8, and the frequency domain range 7 is 80MHz and the frequency domain range 8 is 160MHz. The second information can be used to indicate that the RUs in the frequency domain range 7 are discrete RUs, and indicate that the discrete bandwidth of the discrete RUs in the frequency domain range 7 is 40MHz; the second information is also used to indicate that the RUs in the frequency domain range 8 are discrete RUs, and indicate that the discrete bandwidth of the discrete RUs in the frequency domain range 8 is 160MHz.

[0215] In addition, for the one or more frequency domain ranges included in the second frequency domain range, the number of discrete bandwidths of the discrete RU in each of the one or more frequency domain ranges can be one or more. For example, the second frequency domain range includes the frequency domain range 9, and the frequency domain range 9 is 80MHz, the second information can be used to indicate that the RU in the frequency domain range 9 is a discrete RU, and the discrete bandwidth of the discrete RU in the frequency domain range 9 is 20MHz and 40MHz.

[0216] The bandwidth size of the first frequency domain range and the second frequency domain range can be the same or different. For example, the first frequency domain range and the second frequency domain range are both 80MHz; or the first frequency domain range is 80MHz, and the second frequency domain range is 160MHz, etc.

[0217] The discrete bandwidth of the discrete RU in the second frequency domain range can be one or more bandwidths. For example, the discrete bandwidth of the discrete RU in the second frequency domain range can be 80MHz, or the discrete bandwidth of the discrete RU in the second frequency domain range can include 20MHz and 40MHz. In addition, in the case where the discrete bandwidth of the discrete RU in the second frequency domain range is multiple bandwidths, the frequency domain positions of the multiple discrete bandwidths are different, that is, there is no intersection between the multiple discrete bandwidths. For example, as shown in FIG. 10, assuming that the second frequency domain range is 80MHz, and the discrete bandwidth of the discrete RU in the second frequency domain range includes 20MHz and 40MHz, the frequency domain position corresponding to 20MHz and the frequency domain position corresponding to 40MHz are different.

[0218] It should be noted that the discrete bandwidth of the discrete RU in the second frequency domain range can be referred to as the discrete bandwidth corresponding to the second frequency domain range, the discrete bandwidth covered by the second frequency domain range, the discrete RU on the second frequency domain range, or the discrete RU in the second frequency domain range, etc., which is not limited in the present application.

[0219] Optionally, in the case where the second information is used to indicate that the RU in the first frequency domain range is a continuous RU, and the RU in the second frequency domain range is a discrete RU and the discrete bandwidth of the discrete RU in the second frequency domain range, the first frequency domain range and the second frequency domain range are different frequency domain ranges. Different frequency domain ranges do not mean the size of the frequency domain range, but mean the frequency domain position or distribution position is different. In addition, the first frequency domain range and the second frequency domain range can also mean that the first frequency domain range and the second frequency domain range do not have an intersection.

[0220] S902, the first device transmits data on the first RU, the first RU being determined according to the first information and the second information.

[0221] The first RU can be understood as a wireless resource indicated by the second device to the first device through the first information and the second information, or can also be understood as a resource unit allocated by the second device to the first device through the trigger frame.

[0222] In addition, the first device can also send a data unit based on the received trigger frame, and the data unit includes the first RU. The data unit can be understood as a PPDU, such as an EHT TB PPDU, etc.

[0223] The information transmission method of the present application carries the second information in the common field and / or special user information field in the trigger frame, so that multiple first devices can read the second information, and respectively determine the resource unit allocated to each first device based on the second information. Compared with respectively indicating the resource unit of different first devices through the user information field matched by each first device, it helps to reduce the signaling overhead of the trigger frame.

[0224] Moreover, if the allocated resource unit of each first device is respectively indicated through the user information field matched by each first device, due to the resource shortage in the user information field in the trigger frame, the user information field may not be sufficient to carry the information of all first devices for indicating the allocated resource unit. Through the information transmission method of the present application, the common part of the information of all first devices for indicating the allocated resource unit can be put into the common information field or the special user information field, so that the second device can allocate resource units for one or more first devices through the trigger frame.

[0225] In addition, by carrying the second information in the common field and / or special user information field in the trigger frame, the second information read by multiple first devices is the same, so as to help reduce the conflict of the resource units allocated by the second device for multiple first devices.

[0226] Exemplarily, the multiple first devices are all in one frequency domain range, then the multiple first devices can determine whether the resource unit in the frequency domain range is a discrete resource unit or a continuous resource unit through the second information, and in the case of determining that the resource unit in the frequency domain range is a discrete resource unit, the discrete bandwidth of the discrete resource unit in the frequency domain range can also be determined.

[0227] However, if the resource units are indicated by different user information fields for different first devices, for multiple first devices in the same frequency domain range, part of the first devices can determine the resource units in the frequency domain range as discrete resource units, and another part of the first devices can determine the resource units in the frequency domain range as continuous resource units, so that the resource units corresponding to the multiple first devices in the frequency domain range conflict. Or, for multiple first devices in the same frequency domain range, part of the first devices can be indicated that the discrete bandwidth of the discrete resource units in the frequency domain range is bandwidth 1, and another part of the first devices can be indicated that the discrete bandwidth of the discrete resource in the frequency domain range is bandwidth 2, and the frequency domain positions of bandwidth 1 and bandwidth 2 also have an intersection, so that the discrete distribution manner of the discrete units corresponding to the frequency domain range conflicts.

[0228] Next, the manner in which the first device determines the first RU according to the first information and the second information is described.

[0229] In one possible implementation, the first RU is the first continuous RU.

[0230] The first device can determine the position and size of the first continuous RU according to the first information. Then, the first device can directly determine that the first continuous RU is located in a certain frequency domain range according to the first continuous RU; and in combination with the second information, the first device can determine that the frequency domain range in which the first continuous RU is located is the first frequency domain range corresponding to the continuous RU. In this way, the first device can determine that the first continuous RU is a continuous RU, and the first device can determine that the allocated first RU is the first continuous RU. Exemplarily, in combination with FIG. 7, if the first information indicates the first 52-tone RU, and the second information indicates that the RU in the 80MHz shown in FIG. 7 is a continuous RU, the first device can determine that the first RU is the first 52-tone RU.

[0231] In another possible implementation, the first RU is a discrete RU determined by mapping the first continuous RU on the discrete bandwidth corresponding to the first continuous RU, and the discrete bandwidth corresponding to the first continuous RU is determined based on the first information and the discrete bandwidth of the discrete RU in the second frequency domain range.

[0232] The discrete bandwidth corresponding to the first continuous RU belongs to the discrete bandwidth of the discrete RU in the second frequency domain range. If the discrete bandwidth of the discrete RU in the second frequency domain range is one discrete bandwidth, for example, the second frequency domain range and the discrete bandwidth of the discrete RU in the second frequency domain range are both 80 MHz, the discrete bandwidth corresponding to the first continuous RU is 80 MHz. If the discrete bandwidth of the discrete RU in the second frequency domain range is multiple discrete bandwidths, the first device can determine the discrete bandwidth in which the first continuous RU is located according to the position of the first continuous RU and the position of the multiple discrete bandwidths. For example, in combination with FIG. 10, if the position of the first continuous RU is located in 20 MHz, the discrete bandwidth corresponding to the first continuous RU is 20 MHz.

[0233] It should be understood that in the drawings of the embodiments of the present application, the frequency domain part filled with shading can represent a punctured subchannel, and for the sake of brevity, this will not be described below.

[0234] The subcarrier distribution mode corresponding to the discrete bandwidth corresponding to the first continuous RU can include multiple discrete RUs. For example, the discrete bandwidth corresponding to the first continuous RU is 20 MHz, and the subcarrier distribution mode corresponding to the discrete bandwidth 20 MHz is shown in Table 5, then the subcarrier distribution mode corresponding to the discrete bandwidth 20 MHz includes 9 discrete RUs with RU numbers 1 to 9. The position of the first continuous RU has an association relationship with part or all of the multiple discrete RUs. In this way, the first device can determine part of the discrete RUs associated with the position of the first continuous RU based on the association relationship. The first RU is the part of the discrete RUs.

[0235] For example, in combination with FIG. 11, if the first information indicates that the first continuous RU is the 26-tone RU 1101, and the second information indicates that the RU in the 80 MHz is a discrete RU, and the discrete bandwidth of the discrete RU in the 80 MHz includes the discrete bandwidth 1002, that is, 40 MHz, and also includes the discrete bandwidth 1003, that is, 20 MHz. In combination with the position of the first continuous RU, the first device can determine that the discrete bandwidth corresponding to the first continuous RU is the discrete bandwidth 1003. The subcarrier distribution of the discrete bandwidth 1003 is shown in Table 5. The 9 26-tone RUs included in the discrete bandwidth 1003 are each associated with one of the 9 26-tone RUs with RU numbers 1 to 9. The 26-tone RU 1101 is the fourth 26-tone RU 1101, and the 26-tone RU 1101 can be associated with the 26-tone RU with RU number 4. In this way, the first device can map the 26-tone RU 1001 on the discrete bandwidth 1003, and determine that the first RU is the 26-tone RU with RU number 4.

[0236] It should be understood that the jth consecutive RU in the normal subcarrier distribution of the bandwidth 1 is associated with the discrete RU numbered j in the discrete subcarrier distribution of the bandwidth 1, where the size of the jth consecutive RU is the same as that of the discrete RU numbered j. j is a positive integer.

[0237] It should be noted that the association relationship shown above is only an example, and the embodiments of the present application do not limit the specific content of the association relationship.

[0238] In addition, for the second information, the second information can include a plurality of sub-information, to respectively indicate the content about the first frequency domain range and the content about the second frequency domain range; or the second information can also be one information, that is, the one information indicates the content about the first frequency domain range and the content about the second frequency domain range. The following will be described respectively.

[0239] The first case is that the second information can include a plurality of sub-information.

[0240] As an optional embodiment, the second information includes the first sub-information and / or the second sub-information, the first sub-information is used to indicate that the RU in the first frequency domain range is a consecutive RU, and the second sub-information is used to indicate that the RU in the second frequency domain range is a discrete RU and indicate the discrete bandwidth of the discrete RU in the second frequency domain range.

[0241] Wherein, the second sub-information is used to indicate that the RU in the second frequency domain range is a discrete RU and indicate the discrete bandwidth of the discrete RU in the second frequency domain range, which is not necessarily that the second sub-information includes the information used to indicate that the RU in the second frequency domain range is a discrete RU and the information used to indicate the discrete bandwidth of the discrete RU in the second frequency domain range. The second sub-information used to indicate that the discrete RU in the second frequency domain range is a discrete RU and indicate the discrete bandwidth of the discrete RU in the second frequency domain range can also be understood as that the second sub-information is used to indicate the discrete bandwidth of the discrete RU in the second frequency domain range. For the first device, in the case of reading the second sub-information to determine the discrete bandwidth of the discrete RU in the second frequency domain range, the first device can also determine that the RU in the second frequency domain range is a discrete RU.

[0242] It should be noted that, in a case where the second information is used to indicate that the RU in the first frequency domain range is a continuous RU, the second information can include the first sub-information; in a case where the second information is used to indicate that the RU in the second frequency domain range is a discrete RU and a discrete bandwidth of the discrete RU in the second frequency domain range, the second information can include the second sub-information; and in a case where the second information is used to indicate that the RU in the first frequency domain range is a continuous RU and indicate that the RU in the second frequency domain range is a discrete RU and a discrete bandwidth of the discrete RU in the second frequency domain range, the second information includes the first sub-information and the second sub-information.

[0243] In this case, the number of sub-information included in the second information can be the number of frequency domain ranges included in the first bandwidth. That is, if the first bandwidth includes the first frequency domain range and the second frequency domain range, the second information includes the first sub-information and the second sub-information; if the first bandwidth includes the first frequency domain range, the second information includes the first sub-information; and if the first bandwidth includes the second frequency domain range, the second information includes the second sub-information.

[0244] It should be noted that, in a case where the first frequency domain range includes a plurality of frequency domain ranges, the first sub-information can be a plurality of sub-information, and the plurality of sub-information included in the first sub-information and the plurality of frequency domain ranges included in the first frequency domain range are in one-to-one correspondence. For example, the first frequency domain range includes a frequency domain range 1 and a frequency domain range 2, and the first sub-information can include a first sub-information 1 and a first sub-information 2. The first sub-information 1 is used to indicate that the RU in the frequency domain range 1 is a continuous RU, and the first sub-information 2 is used to indicate that the RU in the frequency domain range 2 is a continuous RU.

[0245] Similarly, in a case where the second frequency domain range includes a plurality of frequency domain ranges, the second sub-information can be a plurality of sub-information, and the plurality of sub-information included in the second sub-information and the plurality of frequency domain ranges included in the second frequency domain range are in one-to-one correspondence. For example, the second frequency domain range includes a frequency domain range 5 and a frequency domain range 6, and the second sub-information can include a second sub-information 1 and a second sub-information 2. The second sub-information 1 is used to indicate that the RU in the frequency domain range 5 is a discrete RU and a discrete bandwidth of the discrete RU in the frequency domain range 5, and the second sub-information 2 is used to indicate that the RU in the frequency domain range 6 is a discrete RU and a discrete bandwidth of the discrete RU in the frequency domain range 6.

[0246] Through such an implementation, the second device can indicate, through the sub-information corresponding to each frequency domain range, that the RU in the frequency domain range is a discrete RU and a discrete bandwidth of the discrete RU in the frequency domain range, or that the RU in the frequency domain range is a continuous RU.

[0247] Exemplarily, as shown in FIG. 12, it is assumed that the first bandwidth is 320MHz, the first bandwidth includes a first frequency domain range and a second frequency domain range, the first frequency domain range includes one frequency domain range, and the second frequency domain range includes three frequency domain ranges, i.e., a second frequency domain range 1, a second frequency domain range 2 and a second frequency domain range 3. Each of the first frequency domain range and the second frequency domain range is 80MHz. Correspondingly, the number of the first sub-information is 1, and the first sub-information is used to indicate that the RU in the first frequency domain range is a continuous RU. The number of the second sub-information is 3, i.e., a second sub-information 1, a second sub-information 2 and a second sub-information 3. The second sub-information 1 is used to indicate that the RU in the second frequency domain range 1 is a discrete RU, and indicate the discrete bandwidth of the discrete RU in the second frequency domain range 1; the second sub-information 2 is used to indicate that the RU in the second frequency domain range 2 is a discrete RU, and indicate the discrete bandwidth of the discrete RU in the second frequency domain range 2; and the second sub-information 3 is used to indicate that the RU in the second frequency domain range 3 is a discrete RU, and indicate the discrete bandwidth of the discrete RU in the second frequency domain range 3.

[0248] It should be noted that in the embodiment of the present application, the first device can not only determine the size of the discrete bandwidth corresponding to the first continuous RU according to the first information and the second information, but also determine the frequency domain position of the discrete bandwidth corresponding to the first continuous RU. Exemplarily, in combination with FIG. 12, the discrete RU in the second frequency domain range 3 is 20MHz+20MHz. If the first device determines that the first continuous RU is located in the left 20MHz, the first device can determine that the discrete bandwidth corresponding to the first continuous RU is 20MHz, and the first device can also determine that the first continuous RU is discrete in the left 20MHz, rather than the right 20MHz. Similarly, if the first device determines that the first continuous RU is located in the right 20MHz, the first device can determine that the discrete bandwidth corresponding to the first continuous RU is 20MHz, and the first device can also determine that the first continuous RU is discrete in the right 20MHz, rather than the left 20MHz.

[0249] The discrete bandwidth of the discrete RU in the second frequency domain range can be one or more, and in the case that the discrete bandwidth of the discrete RU in the second frequency domain range is more than one, the multiple discrete bandwidths can also be the same or different. Next, three ways in which the second sub-information indicates different forms of the discrete bandwidth of the discrete RU in the second frequency domain range are described.

[0250] Optionally, the second sub-information is used to indicate that the discrete bandwidth of the discrete RU in the second frequency domain range includes a first discrete bandwidth and a second discrete bandwidth, the second frequency domain range includes a first sub-frequency domain range and a second sub-frequency domain range, the discrete bandwidth of the discrete RU in the first sub-frequency domain range is the first discrete bandwidth, and the discrete bandwidth of the discrete RU in the second sub-frequency domain range is the second discrete bandwidth.

[0251] It can be seen that in the first mode, the number of discrete bandwidths of the discrete RU in the second frequency domain range is multiple. In this mode, the second frequency domain range includes multiple sub-frequency domain ranges. The multiple sub-frequency domain ranges correspond to the multiple discrete bandwidths one by one.

[0252] In this way, when the first continuous RU is located in the first sub-frequency domain range, it can be determined that the discrete bandwidth of the first continuous RU is the first discrete bandwidth; when the first continuous RU is located in the second sub-frequency domain range, it can be determined that the discrete bandwidth of the first continuous RU is the second discrete bandwidth.

[0253] The first discrete bandwidth and the second discrete bandwidth can be the same or different bandwidths. For example, the first discrete bandwidth and the second discrete bandwidth are both 20 MHz; or the first discrete bandwidth is 40 MHz and the second discrete bandwidth is 20 MHz; or the first discrete bandwidth is 80 MHz and the second discrete bandwidth is 160 MHz, etc.

[0254] It should be noted that in the case where the first sub-frequency domain range and the second sub-frequency domain range are respectively located in the front half and the back half of the second frequency domain range, the two discrete bandwidths can also be referred to as left first discrete bandwidth + right second discrete bandwidth. The front half can also be understood as a half of the frequency domain range located at a lower frequency in the second frequency domain range; the back half can also be understood as a half of the frequency domain range located at a higher frequency in the second frequency domain range. And left first discrete bandwidth + right second discrete bandwidth means that when the first continuous RU is located in the front half of the second frequency domain range, the discrete bandwidth corresponding to the first continuous RU is the first discrete bandwidth; when the first continuous RU is located in the back half of the second frequency domain range, the discrete bandwidth corresponding to the first continuous RU is the second discrete bandwidth.

[0255] For example, in combination with FIG. 12, the front half of the second frequency domain range 1 can be 20 MHz and 20 MHz corresponding to the punctured subchannel, and the back half can be 40 MHz; therefore, the discrete bandwidth of the discrete RU in the second frequency domain range 1 can be represented as left 20 MHz + right 40 MHz.

[0256] It should be noted that in the case that the second sub-information indicates the discrete bandwidth of the discrete RU in the second frequency domain range as the left first discrete bandwidth + the right second discrete bandwidth, it can also be indicated that the front half of the second frequency domain range corresponds to one or more first discrete bandwidths, and the back half of the second frequency domain range corresponds to one or more second discrete bandwidths. For example, if the second frequency domain range is 80 MHz, and the discrete bandwidth corresponding to the second frequency domain range includes 20 MHz in the front half + 20 MHz, and includes 40 MHz in the back half, the second sub-information can also indicate the discrete bandwidth of the discrete RU in the second frequency domain range as left 20 MHz + right 40 MHz. That is, the left 20 MHz can be understood as the discrete bandwidth of the discrete RU in the front half of the frequency domain range being 20 MHz.

[0257] In the case that the first sub-frequency domain range and the second sub-frequency domain range are both in the front half or the back half of the second frequency domain range, and the first sub-frequency domain range and the second sub-frequency domain range are the same, the two discrete bandwidths can also be referred to as the first discrete bandwidth or the second discrete bandwidth. For example, in combination with FIG. 12, the two 20 MHz in the second frequency domain range 3 are both in the back half, and the discrete bandwidth of the discrete RU in the second frequency domain range 3 can be indicated as 20 MHz + 20 MHz.

[0258] In addition, in this manner, the second frequency domain range can include one or more frequency domain ranges.

[0259] When the second frequency domain range includes one frequency domain range, the one frequency domain range can be, for example, any one of 20 MHz, 40 MHz, 80 MHz, 160 MHz, or 320 MHz. The sum of the first sub-frequency domain range and the second sub-frequency domain range is less than or equal to the first frequency domain range. For example, the first frequency domain range is 80 MHz, the first sub-frequency domain range is 20 MHz, and the second sub-frequency domain range is 20 MHz. Alternatively, the first sub-frequency domain range is 40 MHz, and the second sub-frequency domain range is 40 MHz.

[0260] In a case that the second frequency domain range includes a plurality of frequency domain ranges, the plurality of frequency domain ranges can be identical, and the first sub-frequency domain range and / or the second sub-frequency domain range can include one or more frequency domain ranges, and the sum of the first discrete bandwidth and the second discrete bandwidth is the second frequency domain range. Correspondingly, the second sub-information includes a plurality of second sub-information. For example, as shown in FIG. 13, the second frequency domain range includes a second frequency domain range 5, a second frequency domain range 6 and a second frequency domain range 7, and each of the second frequency domain range 5, the second frequency domain range 6 and the second frequency domain range 7 is 80 MHz. The second sub-information includes a second sub-information 5, a second sub-information 6 and a second sub-information 7. The second sub-information 5 is used to indicate that the discrete bandwidth of the discrete RU in the first sub-frequency domain range (the second frequency domain range 5) is 80 MHz; the second sub-information 6 is used to indicate that the discrete bandwidth of the discrete RU in the second frequency domain range 6 is 160 MHz, and the second sub-information 7 is used to indicate that the discrete bandwidth of the discrete RU in the second frequency domain range 7 is 160 MHz, and the second frequency domain range 6 and the second frequency domain range 7 can be understood as the second sub-frequency domain range.

[0261] It can be understood that, in a case that the second frequency domain range includes a plurality of frequency domain ranges, part of the plurality of frequency domain ranges can correspond to the same discrete bandwidth. The number of frequency domain ranges included in the part of the plurality of frequency domain ranges is greater than 1. For example, in combination with FIG. 13, the second frequency domain range includes three frequency domain ranges, and the second frequency domain range 6 and the second frequency domain range 7 correspond to the same discrete bandwidth, i.e., the discrete bandwidth is 160 MHz, and the second frequency domain range 6 and the second frequency domain range 7 are part of the plurality of frequency domain ranges.

[0262] In a second mode, the second sub-information is used to indicate that the discrete bandwidth of the discrete RU in the second frequency domain range includes a third discrete bandwidth, and the discrete bandwidth of the discrete RU in the second frequency domain range is the third discrete bandwidth.

[0263] The third discrete bandwidth can be equal to the second frequency domain range. For example, the second frequency domain range is 80 MHz, and the third discrete bandwidth can be 80 MHz. Alternatively, the second frequency domain range is 160 MHz, and the third discrete bandwidth can be 160 MHz.

[0264] In addition, the second frequency domain range can include one or more frequency domain ranges. In a case that the second frequency domain range includes one frequency domain range, the second sub-information includes one sub-information, and the third discrete bandwidth is the same as the one second frequency domain range. For example, as shown in FIG. 13, it is assumed that the second frequency domain range is the second frequency domain range 5, and the second sub-information is the second sub-information 5, and the second sub-information 5 indicates that the discrete bandwidth of the RU in the second frequency domain range 5 is 80 MHz, i.e., the third discrete bandwidth is 80 MHz.

[0265] The sizes of the plurality of frequency domain ranges can be the same when the second frequency domain range comprises the plurality of frequency domain ranges. The second sub-information comprises a plurality of sub-information. The third discrete bandwidth is the same as the sum of the plurality of frequency domain ranges comprised by the second frequency domain range. For example, as shown in FIG. 13, assuming that the second frequency domain range comprises the second frequency domain range 6 and the second frequency domain range 7, the second frequency domain range 6 and the second frequency domain range 7 are both 80 MHz. The second sub-information comprises the second sub-information 6 and the second sub-information 7. The second sub-information 6 is used to indicate that the discrete bandwidth of the discrete RU in the second frequency domain range 6 is 160 MHz, and the second sub-information 7 is used to indicate that the discrete bandwidth of the discrete RU in the second frequency domain range 7 is 160 MHz. Then the third discrete bandwidth is 160 MHz. Alternatively, the second sub-information 6 and the second sub-information 7 can also be replaced by one information, that is, the one information indicates that the discrete bandwidth of the discrete RU in the second frequency domain range 6 and the discrete bandwidth of the discrete RU in the second frequency domain range 7 are both 160 MHz. For example, the one information can be 1 bit, etc.

[0266] In the third mode, the second sub-information is used to indicate that the discrete bandwidth of the discrete RU in the second frequency domain range comprises a fourth discrete bandwidth, the second frequency domain range comprises i third sub-frequency domain ranges, the discrete bandwidth of the discrete RU in each of the i third sub-frequency domain ranges is the fourth discrete bandwidth, and i is a positive integer. When i is 1, the third sub-frequency domain range can be smaller than the second frequency domain range.

[0267] The sum of the i third sub-frequency domain ranges can be smaller than or equal to the second frequency domain range. For example, in combination with FIG. 12, assuming that the second frequency domain range is the second frequency domain range 3, the third sub-frequency domain range can be 20 MHz, i is 2, and the fourth discrete bandwidth is 20 MHz. Alternatively, assuming that the second frequency domain range is 80 MHz, the third sub-frequency domain range can be 20 MHz, i is 1, and the fourth discrete bandwidth is 20 MHz. Alternatively, as shown in FIG. 14, the second frequency domain range is 80 MHz, the third sub-frequency domain range can be 20 MHz, i is 4, and the fourth discrete bandwidth is 20 MHz.

[0268] In this mode, the second sub-information can be used to indicate that the fourth discrete bandwidth represents the discrete bandwidth of the discrete RU in the second frequency domain range. For example, the second sub-information can be 20 MHz, that is, the discrete bandwidth of the discrete RU in the second frequency domain range is all 20 MHz.

[0269] It should be noted that any multiple of the first mode, the second mode and the third mode described above can also be combined. For example, in the case where the second frequency domain range includes multiple frequency domain ranges, the second sub-information includes multiple sub-information, and the multiple frequency domain ranges included in the second frequency domain range correspond to the multiple sub-information included in the second sub-information one by one; then the u frequency domain ranges and the u sub-information corresponding to the u frequency domain ranges can satisfy the first mode; the v frequency domain ranges and the v sub-information corresponding to the v frequency domain ranges can satisfy the second mode; and the w frequency domain ranges and the w sub-information corresponding to the w frequency domain ranges can satisfy the third mode. u, v, and w are integers greater than or equal to 0. For example, in combination with FIG. 12, the second frequency domain range 1, the second sub-information 1, the second frequency domain range 3, and the second sub-information 3 satisfy the first mode, and the second frequency domain range 2 and the second sub-information 2 satisfy the second mode.

[0270] On the basis of the above embodiment, the discrete bandwidth corresponding to the first continuous RU is the smaller one of the bandwidth of the data unit and the discrete bandwidth of the discrete RU in the second frequency domain range.

[0271] In the above embodiment, the data unit in the bandwidth of the data unit can be understood as a data unit corresponding to the first RU or the first continuous RU, or a data unit to which the first RU belongs, and the like.

[0272] It can be understood that if the bandwidth of the data unit is smaller than the discrete bandwidth of the discrete RU in the second frequency domain range, the discrete bandwidth corresponding to the first continuous RU is the bandwidth of the data unit. If the bandwidth of the data unit is greater than or equal to the discrete bandwidth of the discrete RU in the second frequency domain range, the discrete bandwidth corresponding to the first continuous RU is the discrete bandwidth of the discrete RU in the second frequency domain range.

[0273] For example, assuming that the discrete bandwidth of the discrete RU in the second frequency domain range is 80MHz, and the bandwidth of the data unit is 40MHz, the discrete bandwidth corresponding to the first continuous RU is 40MHz; assuming that the discrete bandwidth of the discrete RU in the second frequency domain range is 80MHz, and the bandwidth of the data unit is 160MHz, the discrete bandwidth corresponding to the first continuous RU is 80MHz; or, assuming that the discrete bandwidth of the discrete RU in the second frequency domain range is left 20MHz + right 40MHz, and the bandwidth of the data unit is 20MHz; if the first continuous RU is in the range corresponding to the right 40MHz, the discrete bandwidth corresponding to the first continuous RU is the bandwidth of the data unit, i.e. 20MHz.

[0274] In the second manner above, in a case where the bandwidth of the data unit is less than the second frequency domain range, the third discrete bandwidth can be the bandwidth of the data unit; in a case where the bandwidth of the data unit is greater than or equal to the second frequency domain range, the third discrete bandwidth can be equal to the second frequency domain range.

[0275] It should be understood that, in addition to the three manners above, in some possible implementation, the second information can also be used to indicate that the RUs in one part of the one frequency domain range are continuous RUs, the RUs in another part of the one frequency domain range are discrete RUs, and the discrete bandwidth of the discrete RUs in the other part of the one frequency domain range. For example, assuming that the one frequency domain range is 80 MHz, the second information can indicate that the RUs in the first half (40 MHz) of the 80 MHz are continuous RUs, the RUs in the second half (40 MHz) of the 80 MHz are discrete RUs, and the discrete bandwidth of the discrete RUs in the second half (40 MHz) of the 80 MHz is 40 MHz.

[0276] In the above embodiment, the second information used to indicate that the RUs in the other part of the one frequency domain range are discrete RUs and the discrete bandwidth of the discrete RUs in the other part of the one frequency domain range can also be replaced by the second information used to indicate the discrete bandwidth of the discrete RUs in the other part of the one frequency domain range. That is, in a case where the second information indicates the discrete bandwidth of the discrete RUs in the other part of the one frequency domain range, the first device can also determine or default that the RUs in the other part of the one frequency domain range are discrete RUs.

[0277] On the basis of the above embodiment, the first sub-information and / or the second sub-information can be in the following forms.

[0278] Form one, the first sub-information is H bits and / or the second sub-information is Z bits. H and Z are positive integers.

[0279] For example, H and Z can be 2, 4, etc. The first sub-information can include one or more sub-information, the second sub-information can include one or more sub-information, and the number of bits corresponding to each sub-information in the first sub-information and the number of bits corresponding to each sub-information in the second sub-information can be the same. In this way, the second information can indicate that each of the plurality of frequency domain ranges is continuous RU by the same number of bits, or indicate that each of the plurality of frequency domain ranges is discrete RU and the discrete bandwidth of the discrete RUs in the frequency domain range by the same number of bits.

[0280] Hereinafter, taking an example in which the number of bits corresponding to each sub-information in the first sub-information and the number of bits corresponding to each sub-information in the second sub-information are both 2 bits.

[0281] The second sub-information indicates a discrete bandwidth of a discrete RU in the second frequency domain range in the second manner.

[0282] As shown in Table 8, 00 can represent that the RU in one frequency domain range is a continuous RU; 01 represents that the RU in one frequency domain range is a discrete RU, and the discrete bandwidth of the discrete RU in the one frequency domain range is the smaller one of a frequency domain range and the bandwidth of the data unit; 10 can represent that the RU in one frequency domain range is a discrete RU, and the discrete bandwidth of the discrete RU in the one frequency domain range is left 20 MHz + right 40 MHz; and 11 can represent that the RU in one frequency domain range is a discrete RU, and the discrete bandwidth of the discrete RU in the one frequency domain range is left 40 MHz + right 20 MHz.

[0283] Table 8

[0284] Exemplarily, it is assumed that the second frequency domain ranges include the second frequency domain range 8, the second frequency domain range 9, and the second frequency domain range 10. The number of bits corresponding to each sub-information in the first sub-information and the number of bits corresponding to each sub-information in the second sub-information are both 2 bits. Then the first sub-information is 00, and the second sub-information includes the second sub-information 8 corresponding to the second frequency domain range 8, the second sub-information 9 corresponding to the second frequency domain range 9, and the second sub-information 10 corresponding to the second frequency domain range 10. The second sub-information 8 is 10, the second sub-information 9 is 01, and the second sub-information 10 is 11.

[0285] On the basis of the above-described embodiments, optionally, in the case where the second information includes a plurality of sub-information, and the plurality of sub-information respectively correspond to a plurality of frequency domain ranges, then the plurality of sub-information in the first arrangement order respectively correspond to the plurality of frequency domain ranges in the second arrangement order in sequence. The first arrangement order may, for example, be from left to right, from top to bottom, or the order in which the first device reads the plurality of sub-information, etc. The second arrangement order may, for example, be from low to high or from high to low, etc. Exemplarily, in the order in which the first device reads the plurality of sub-information, the plurality of sub-information are 00, 01, 10, and 11 in sequence; and in the order from low to high, the four frequency domain ranges are the first frequency domain range, the second frequency domain range 8, the second frequency domain range 9, and the second frequency domain range 10 in sequence. 00 is used to represent that the RU in the first frequency domain range is a continuous RU. By analogy, 01 corresponds to the second frequency domain range 8; 10 corresponds to the second frequency domain range 9; and 11 corresponds to the second frequency domain range 10.

[0286] The length of the plurality of sub-information included in the second information can be proportional to the size of the bandwidth of the data unit. For example, when the bandwidth of the data unit is 320MHz, the plurality of sub-information included in the second information can be 8 bits; when the bandwidth of the data unit is 160MHz, the plurality of sub-information included in the second information can be 4 bits, and so on. By analogy.

[0287] It should be understood that the possible forms shown in Table 8 can be the first sub-information and the second sub-information. However, for the same frequency domain range, the corresponding sub-information is any one of the first sub-information or the second sub-information, for example, any one of the plurality of sub-information shown in Table 8. That is, if the RU in the one frequency domain range is a continuous RU, the corresponding sub-information of the one frequency domain range is the first sub-information, for example, 00 in Table 8; if the RU in the one frequency domain range is a discrete RU, the corresponding sub-information of the one frequency domain range is the second sub-information, for example, 01, 10 or 11 in Table 8.

[0288] It should also be understood that Table 8 is only an example, and for any one or several of the second sub-information, the discrete bandwidth of the discrete RU in any sub-frequency domain range in the one frequency domain range can be: the smaller one of the bandwidth of the data unit and the bandwidth of the any sub-frequency domain range. This will not be described again below.

[0289] The any sub-frequency domain range can refer to part or all of the frequency domain range in the one frequency domain range. For example, the one frequency domain range is 80MHz, and the any sub-frequency domain range can be 80MHz, 20MHz or 40MHz, and so on.

[0290] In combination with Table 8, the one frequency domain range is 80MHz, and 10 can also represent that the RU in the sub-frequency domain range corresponding to the left 20MHz is a discrete RU, and the discrete bandwidth of the discrete RU in the sub-frequency domain range corresponding to the left 20MHz is the smaller one of 20MHz and the bandwidth of the data unit; also represent that the RU in the sub-frequency domain range corresponding to the right 40MHz is a discrete RU, and the discrete bandwidth of the discrete RU in the sub-frequency domain range corresponding to the right 40MHz is the smaller one of 40MHz and the bandwidth of the data unit. It can also be represented as DBW = left Min(20MHz, PPDU BW) + right Min(40MHz, PPDU BW). Wherein, PPDU BW is the bandwidth of the data unit. By analogy, for other sub-information, the discrete bandwidth can also be indicated in this way, which will not be listed one by one here.

[0291] It should be noted that, in combination with the second manner in the foregoing, in a case where the bandwidth of the data unit is less than the second frequency domain range, the third discrete bandwidth can be the bandwidth of the data unit; in a case where the bandwidth of the data unit is greater than or equal to the second frequency domain range, the third discrete bandwidth can be equal to the second frequency domain range. Therefore, as the size of each frequency domain range in the second frequency domain range is different, the third discrete bandwidth indicated by the second sub-information can be different.

[0292] Correspondingly, the meaning of 2 bits can be as shown in Table 9, and the meanings of 00, 10, and 11 are similar to those in Table 8, and can be referred to the description in the foregoing. For 01, the following meanings can also exist. The meaning of 01 is a first meaning: in a case where the bandwidth of the data unit is greater than or equal to 80 MHz, the discrete bandwidth of the discrete RU in one frequency domain range is 80 MHz; in a case where the bandwidth of the data unit is equal to 40 MHz, the discrete bandwidth of the discrete RU in one frequency domain range is 40 MHz; in a case where the bandwidth of the data unit is equal to 20 MHz, the discrete bandwidth of the discrete RU in one frequency domain range is 20 MHz. The meaning of 01 is a second meaning: in a case where the bandwidth of the data unit is greater than or equal to 160 MHz, the discrete bandwidth of the discrete RU in one frequency domain range is 160 MHz; in a case where the bandwidth of the data unit is equal to 80 MHz, the discrete bandwidth of the discrete RU in one frequency domain range is 80 MHz; in a case where the bandwidth of the data unit is equal to 40 MHz, the discrete bandwidth of the discrete RU in one frequency domain range is 40 MHz; in a case where the bandwidth of the data unit is equal to 20 MHz, the discrete bandwidth of the discrete RU in one frequency domain range is 20 MHz.

[0293] Table 9

[0294] In combination with the manner in which the second sub-information indicates the discrete bandwidth of the discrete RU in the second frequency domain range in the second manner and the third manner in the foregoing, the meaning of 2 bits can be as follows.

[0295] As shown in Table 10, 00 indicates that the RU in one frequency domain range is a continuous RU. 01 indicates that the RU in one frequency domain range is a discrete RU, and the discrete bandwidth of the discrete RU in the one frequency domain range is 20 MHz; 10 indicates that the RU in one frequency domain range is a discrete RU, and the discrete bandwidth of the discrete RU in the one frequency domain range is 40 MHz; and 11 indicates that the RU in one frequency domain range is a discrete RU, and the discrete bandwidth of the discrete RU in the one frequency domain range is 80 MHz.

[0296] Table 10

[0297] Exemplarily, the first frequency domain range is 80MHz, and the second frequency domain range includes a second frequency domain range 11, a second frequency domain range 12 and a second frequency domain range 13, each of which is 80MHz. The second sub-information includes a second sub-information 11 corresponding to the second frequency domain range 11, a second sub-information 12 corresponding to the second frequency domain range 12 and a second sub-information 13 corresponding to the second frequency domain range 13. The number of bits corresponding to each sub-information in the first sub-information and the number of bits corresponding to each sub-information in the second sub-information are both 2 bits. The first sub-information is 00, which indicates that the RU in the first frequency domain range is a continuous RU. The second sub-information 11 is 01, which indicates that the RU in the second frequency domain range 11 is a discrete RU, and the discrete bandwidth of the discrete RU in the second frequency domain range 11 is 20MHz; the second sub-information 12 is 10, which indicates that the RU in the second frequency domain range 12 is a discrete RU, and the discrete bandwidth of the discrete RU in the second frequency domain range 12 is 40MHz; and the second sub-information 13 is 11, which indicates that the RU in the second frequency domain range 13 is a discrete RU, and the discrete bandwidth of the discrete RU in the second frequency domain range 13 is 80MHz.

[0298] It should be noted that the second frequency domain range 12 can correspond to one or more 20MHz; the second frequency domain range 13 can correspond to one or two 40MHz, which is not limited in the present application.

[0299] In addition, the meaning of 2 bits can also be as shown in Table 11, 00 indicates that the RU in one frequency domain range is a continuous RU. 01 indicates that the RU in one frequency domain range is a discrete RU, and the discrete bandwidth of the discrete RU in the one frequency domain range is 40MHz; 10 indicates that the RU in one frequency domain range is a discrete RU, and the discrete bandwidth of the discrete RU in the one frequency domain range is 80MHz; and 11 indicates that the RU in one frequency domain range is a discrete RU, and the discrete bandwidth of the discrete RU in the one frequency domain range is 160MHz.

[0300] Table 11

[0301] Exemplarily, the first frequency domain range is 160 MHz, and the second frequency domain range includes a second frequency domain range 14, a second frequency domain range 15 and a second frequency domain range 16, each of which is 160 MHz. The second sub-information includes a second sub-information 14 corresponding to the second frequency domain range 14, a second sub-information 15 corresponding to the second frequency domain range 15, and a second sub-information 16 corresponding to the second frequency domain range 16. The number of bits corresponding to each of the first sub-information and the second sub-information is 2 bits. The first sub-information is 00, which indicates that the RU in the first frequency domain range is a continuous RU. The second sub-information 11 is 01, which indicates that the RU in the second frequency domain range 14 is a discrete RU, and the discrete bandwidth of the discrete RU in the second frequency domain range 14 is 40 MHz. The second sub-information 15 is 10, which indicates that the RU in the second frequency domain range 15 is a discrete RU, and the discrete bandwidth of the discrete RU in the second frequency domain range 15 is 80 MHz. The second sub-information 16 is 11, which indicates that the RU in the second frequency domain range 16 is a discrete RU, and the discrete bandwidth of the discrete RU in the second frequency domain range 16 is 160 MHz.

[0302] It should be noted that the second frequency domain range 14 can correspond to one or more 40 MHz; the second frequency domain range 15 can correspond to one or two 80 MHz, which is not limited in the present application.

[0303] By using the above manner, the signaling overhead of the trigger frame can be small. Exemplarily, assuming that the second device needs to indicate the dRU for 10 first devices. If the second device respectively indicates the dRU for each of the 10 first devices, assuming that 1 bit is respectively used to indicate that the continuous RU of each first device is a discrete RU, and 2 bits are respectively used to indicate the discrete bandwidth of the discrete RU of each first device, the trigger frame needs a total of 30 bits to indicate this part of content. If the trigger frame uses the above manner to indicate the discrete bandwidth corresponding to each frequency domain range in 320 MHz to the 10 first devices, the trigger frame needs 8 bits to indicate this part of content.

[0304] It should be noted that the tables 8 to 11 are only examples, and the 2 bits therein can be replaced by other bit numbers, such as 3 bits, etc.; and the meanings of 00, 01, 10 and 11 shown in the tables 8 to 11 can also be replaced by other meanings, for example, 01 in the table 11 can also represent that the RU in the second frequency range 14 is a discrete RU, and the discrete bandwidth of the discrete RU in the second frequency range 14 is 20 MHz, etc.; in addition, the positions of 00, 01, 10 and 11 shown in the tables 8 to 11 can also be interchanged, for example, in the table 8, the three 2 bits below 00 can be switched to 11, 01 and 10 in order from top to bottom (i.e. in order away from 00); and / or, 00 and 01 in the table 11 can be interchanged, i.e. 01 is the first sub-information, 01 is the second sub-information 14, etc., which are not limited in the present application.

[0305] Exemplarily, taking the example that each sub-information is replaced by 3 bits, the meanings of the 3 bits can be as shown in the table 12. That is, 000 represents that the RU in one frequency range is a continuous RU; 001 represents that the RU in one frequency range is a discrete RU, and the discrete bandwidth of the discrete RU in the one frequency range is the smaller one of the one frequency range and the bandwidth of the data unit; 010 can represent that the RU in one frequency range is a discrete RU, and the discrete bandwidth of the discrete RU in the one frequency range is left 20 MHz + right 40 MHz; 011 can represent that the RU in one frequency range is a discrete RU, and the discrete bandwidth of the discrete RU in the one frequency range is left 40 MHz + right 20 MHz; and 100 represents that the RU in one frequency range is a discrete RU, and the discrete bandwidth of the discrete RU in the one frequency range is 160 MHz.

[0306] Table 12

[0307] It should be noted that the tables 8 to 12 are only examples, and each frequency range included in the first frequency range and / or each frequency range included in the second frequency range can be a frequency range other than 80 MHz, such as 20 MHz, 40 MHz or 160 MHz, etc. Correspondingly, the meanings of the corresponding 2 bits or 3 bits in the tables 8 to 12 can also be changed accordingly, for example, when the one frequency range is 40 MHz, 01 in the table 8 can represent that the RU in one frequency range is discrete, and the discrete bandwidth of the discrete RU in the one frequency range is the smaller one of 40 MHz and the bandwidth of the data unit, and the meanings of the other 2 bits can also be replaced by various discrete bandwidths. Similarly, this will not be described here.

[0308] It should be noted that Table 12 is only an example, and the meaning of each 3-bit shown in Table 12 can also be exchanged, for example, 010 indicates that the RUs in one frequency domain range are contiguous RUs; 000 indicates that the RUs in one frequency domain range are discrete RUs, and the discrete bandwidth of the discrete RUs in the one frequency domain range is the smaller one of the bandwidth of the one frequency domain range and the data unit, etc. Also, each 3-bit shown in Table 12 can also be replaced by other forms, for example, 000 can also be replaced by 111, etc., and 111 is used to indicate that the RUs in one frequency domain range are contiguous RUs. Also, the number of 3-bits in Table 12 can be more or less, for example, Table 12 also includes 110, which is used to indicate that the RUs in one frequency domain range are discrete RUs, and the discrete bandwidth of the discrete RUs in the one frequency domain range is 40 MHz; or Table 12 does not include 100, etc. The present application does not make a specific limitation in this regard.

[0309] In Table 12, whether the discrete bandwidth of the discrete RUs in one frequency domain range is equal to the number of frequency domain ranges can be indicated by 3 bits. For example, 000 indicates that the discrete bandwidth of the discrete RUs in the second frequency domain range is not 160 MHz; 100 can indicate that the discrete bandwidth of the discrete RUs in one 80 MHz frequency domain range is 160 MHz. In some possible implementation manners, each of the first sub-information and / or the second sub-information can be as shown in Table 8 to Table 11. In addition, the trigger frame further includes third information, for example, 2 bits carried in the common information field or the special user field.

[0310] For example, if one frequency domain range is 80 MHz, whether the discrete bandwidth of the discrete RUs in 320 MHz is 160 MHz can be indicated by a 2-bit bitmap method. The 2 bits can be used to indicate whether the discrete bandwidth of the two frequency domain ranges included in the first half of 320 MHz is 160 MHz, and whether the discrete bandwidth of the two frequency domain ranges included in the second half of 320 MHz is 160 MHz, respectively. For example, if the two bits are 11, it indicates that the discrete bandwidth of the two frequency domain ranges in the first half of 320 MHz is 160 MHz, and the discrete bandwidth of the two frequency domain ranges in the second half of 320 MHz is 160 MHz; if the two bits are 01, it indicates that the discrete bandwidth of the two frequency domain ranges in the second half of 320 MHz is 160 MHz; if the two bits are 10, it indicates that the discrete bandwidth of the two frequency domain ranges in the first half of 320 MHz is 160 MHz, etc.

[0311] Similarly, in the case of other sizes of the frequency domain range, such as 40 MHz or 160 MHz, etc., the indication of whether the discrete bandwidth of the discrete RU in the second frequency domain range is a multiple of the frequency domain range can also be made in the above manner. Here, it is not listed one by one.

[0312] In addition, the fourth information can also be included in the trigger frame, and the fourth information is used to indicate whether the discrete bandwidth of the discrete RU in the second frequency domain range includes 320 MHz. The fourth information can be, for example, a 1-bit carried in the common information field or the special user information field. When the 1-bit is 1, it can indicate that the discrete bandwidth of the discrete RU in the second frequency domain range includes 320 MHz; when the 1-bit is 0, it can indicate that the discrete bandwidth of the discrete RU in the second frequency domain range does not include 320 MHz. Alternatively, when the 1-bit is 0, it can indicate that the discrete bandwidth of the discrete RU in the second frequency domain range includes 320 MHz; when the 1-bit is 1, it can indicate that the discrete bandwidth of the discrete RU in the second frequency domain range does not include 320 MHz.

[0313] On the basis of the above embodiments, if the size of the first continuous RU is large, and the RU actually allocated to the first device is a discrete RU (the second information indicates that the first continuous RU is in the second frequency domain range, that is, the first continuous RU needs to be discretely arranged on the discrete bandwidth to obtain the corresponding discrete RU), the bandwidth corresponding to the first continuous RU can need to be smaller than the discrete bandwidth corresponding to the first continuous RU. The specific implementation is as follows.

[0314] In a possible implementation, the meaning of any of the plurality of sub-information included in the second information is related to the size of the first continuous RU.

[0315] In this way, for one or more sub-information in the second information, the meaning of the one or more sub-information changes with the change of the size of the first continuous RU. For example, for 01, if the size of the first continuous RU is a 996-tone RU, 01 can indicate that the discrete bandwidth of the discrete RU in the frequency domain range is 160 MHz; if the size of the first continuous RU is a 484-tone RU, 01 can indicate that the discrete bandwidth of the discrete RU in the frequency domain range is 80 MHz, etc.

[0316] Optionally, the second sub-information satisfies the following conditions: condition 1, in a case where the bandwidth corresponding to the first continuous RU is greater than 20 MHz, the discrete bandwidth of the discrete RU in the second frequency domain range indicated by the second sub-information is c times the bandwidth corresponding to the first continuous RU, c is an even number greater than or equal to 2; and / or, condition 2, in a case where the bandwidth corresponding to the first continuous RU is less than or equal to 20 MHz, the discrete bandwidth of the discrete RU in the second frequency domain range indicated by the second sub-information is greater than or equal to 20 MHz.

[0317] For condition 1, the bandwidth corresponding to the first continuous RU being greater than 20 MHz can also be understood as the first continuous RU being an RU with a size greater than a 242-tone RU, such as a 484-tone RU or a 996-tone RU, and the like. In such a case, since the first continuous RU can not be discrete on a partial discrete bandwidth, the discrete bandwidth of the discrete RU in the second frequency domain range is greater than the bandwidth corresponding to the first continuous RU.

[0318] For example, c can be 2, 4, and the like.

[0319] Under condition 1, the meaning of 2 bits is shown in Table 13, assuming that the first continuous RU is a 996-tone RU, and the bandwidth corresponding to the 996-tone RU is 80 MHz. 00 can represent that the RU in one frequency domain range is a continuous RU; 01 can represent that the RU in one frequency domain range is a discrete RU, and the discrete bandwidth of the discrete RU in the one frequency domain range is 160 MHz; 10 can represent that the RU in one frequency domain range is a discrete RU, and the discrete bandwidth of the discrete RU in the one frequency domain range is 320 MHz; and 11 can be reserved.

[0320] Table 13

[0321] Exemplarily, it is assumed that the first continuous RU is a 996-tone RU, and the 996-tone RU corresponds to a bandwidth of 80 MHz. The second frequency domain range includes the second frequency domain range 17 and the second frequency domain range 18. The second sub-information includes the second sub-information 17 corresponding to the second frequency domain range 17, the second sub-information 18 corresponding to the second frequency domain range 18, and a reserved second sub-information. The number of bits corresponding to each sub-information in the first sub-information and the number of bits corresponding to each sub-information in the second sub-information are both 2 bits. The first sub-information can be 00, the second sub-information 17 is 01, the second sub-information 18 is 10, and the reserved second sub-information is 11. 01 is used to indicate that the discrete bandwidth of the discrete RU in the second frequency domain range 17 is 160 MHz, that is, c is 2; 10 is used to indicate that the discrete bandwidth of the discrete RU in the second frequency domain range 18 is 320 MHz, that is, c is 4. Since the discrete bandwidth is usually not more than 320 MHz, 11 can be reserved.

[0322] It should be noted that Table 13 is only an example. In some possible implementation manners, the discrete bandwidth can be less than 320 MHz, and therefore 10 can also be reserved.

[0323] Alternatively, in condition 1, the meaning of 2 bits can also be as shown in Table 14, assuming that the first continuous RU is a 484-tone RU, and the 484-tone RU corresponds to a bandwidth of 40 MHz. 00 can indicate that the RU in one frequency domain range is a continuous RU; 01 can indicate that the RU in one frequency domain range is a discrete RU, and the discrete bandwidth of the discrete RU in the one frequency domain range is 80 MHz; 10 can indicate that the RU in one frequency domain range is a discrete RU, and the discrete bandwidth of the discrete RU in the one frequency domain range is 160 MHz; and 11 can be reserved.

[0324] Table 14

[0325] Exemplarily, assuming that the first continuous RU is a 484-tone RU, and the 484-tone RU corresponds to a bandwidth of 40 MHz. The second frequency domain range includes the second frequency domain range 19 and the second frequency domain range 20. The second sub-information includes the second sub-information 19 corresponding to the second frequency domain range 19, the second sub-information 20 corresponding to the second frequency domain range 20, and a reserved second sub-information. The number of bits corresponding to each sub-information in the first sub-information and the number of bits corresponding to each sub-information in the second sub-information are both 2 bits. The first sub-information can be 00, the second sub-information 19 is 01, the second sub-information 20 is 10, and the reserved second sub-information is 11. 01 is used to indicate that the discrete bandwidth of the discrete RU in the second frequency domain range 19 is 80 MHz, that is, c is 2; 10 is used to indicate that the discrete bandwidth of the discrete RU in the second frequency domain range 20 is 160 MHz, that is, c is 4; and 11 can be reserved.

[0326] Alternatively, in condition 1, the meanings of the 2 bits can also be as shown in Table 15, assuming that the first continuous RU is a 2×996-tone RU, and the 2×996-tone RU corresponds to a bandwidth of 160 MHz. 00 can indicate that the RU in one frequency domain range is a continuous RU; 01 can indicate that the RU in one frequency domain range is a discrete RU, and the discrete bandwidth of the discrete RU in the one frequency domain range is 320 MHz; and 10 and 11 can be reserved.

[0327] Table 15

[0328] Exemplarily, assuming that the first continuous RU is a 2×996-tone RU, and the 2×996-tone RU corresponds to a bandwidth of 160 MHz. The first sub-information is 00, and the second sub-information includes 01, 10, and 11. 01 is used to indicate that the discrete bandwidth of the discrete RU in the second frequency domain range is 320 MHz, that is, c is 2; and 10 and 11 can be reserved.

[0329] It should be noted that for the meanings of each 2 bits shown in Table 13, Table 14, and Table 15, part of the 2 bits can also be reserved or used to indicate other discrete bandwidths as the bandwidth of the data unit changes. Taking Table 13 as an example, this also applies to Table 14 in the case of sizes other than 484-tone RU for the first continuous RU. Exemplarily, assuming that the first continuous RU is a 996-tone RU, 01 can be reserved. In addition, if the discrete bandwidth is 320 MHz, 11 can be used to indicate that the discrete bandwidth is 320 MHz.

[0330] In addition, assuming the first contiguous RU is a 242-tone RU, the discrete bandwidth of the discrete RU in the second frequency domain range can be 40MHz, 80MHz, 160MHz, etc. Correspondingly, the meaning of the 2 bits can refer to Table 11, which is not shown here. That is, 00 can represent that the RU in one frequency domain range is a contiguous RU; 01 can represent that the RU in one frequency domain range is a discrete RU, and the discrete bandwidth of the discrete RU in the one frequency domain range is 40MHz; 10 can represent that the RU in one frequency domain range is a discrete RU, and the discrete bandwidth of the discrete RU in the one frequency domain range is 80MHz; and 11 can represent that the RU in one frequency domain range is a discrete RU, and the discrete bandwidth of the discrete RU in the one frequency domain range is 160MHz.

[0331] It should be understood that when the first contiguous RU is a 242-tone RU, the 2 bits can also be replaced by more bits, and the meaning of each 2 bits can also be other meanings, which are not limited in the present application.

[0332] As can be seen from Table 13, Table 14 and Table 15, for the same second sub-information, the discrete bandwidth of the discrete RU in the second frequency domain range indicated by the second sub-information can be different when the size of the first contiguous RU is different. That is, as shown in Table 16, 01 can represent that the discrete bandwidth of the discrete RU in one second frequency domain range is 2 times the bandwidth corresponding to the first contiguous RU; 10 can represent that the discrete bandwidth of the discrete RU in one second frequency domain range is 4 times the bandwidth corresponding to the first contiguous RU; and 11 can represent that the discrete bandwidth of the discrete RU in one second frequency domain range is 8 times the bandwidth corresponding to the first contiguous RU. Part of 01, 10 or 11 can be reserved.

[0333] Table 16

[0334] For condition 2, the discrete bandwidth of the discrete RU in the second frequency domain range can be one or more of the following: 20MHz, 40MHz, 80MHz, 160MHz or 320MHz. And the indication form of the second sub-information corresponding to condition 2 can refer to the description of the corresponding part of Table 8 to Table 12, which is not described here.

[0335] It should be noted that Tables 13 to 16 are merely examples, and the 2 bits in the above can also be replaced by other bit numbers, such as 3 bits, etc.; and the positions of 00, 01, 10, and 11 shown in Tables 13 to 16 can also be interchanged, for example, 00 and 01 in Table 16 can be interchanged, i.e., 01 is used to indicate that the RU in the first frequency domain range is a continuous RU, 00 is used to indicate that the DBW is 2 times the bandwidth corresponding to the first continuous RU, etc., which is not limited in the present application.

[0336] On the basis of the above embodiment, the manner in which the second sub-information indicates the discrete bandwidth of the discrete RU in the second frequency domain range can also vary with the bandwidth of the data unit, specifically as follows.

[0337] Alternatively, the first frequency domain range and / or the second frequency domain range, and the first sub-information and / or the second sub-information satisfy any one of the following conditions: condition 3, if the bandwidth of the data unit is greater than or equal to a first bandwidth, the first bandwidth includes the first frequency domain range and / or the second frequency domain range, the first frequency domain range and / or the second frequency domain range includes X frequency domain ranges, each of the X frequency domain ranges is a first value, the first value is a ratio of the first bandwidth to X, X is an integer greater than or equal to 1, each of the X sub-information included in the first sub-information and / or the second sub-information is M bits, M is a positive integer, and the X frequency domain ranges and the X sub-information correspond one-to-one; condition 4, if the bandwidth of the data unit is 1 / a of the first bandwidth, each of the X sub-information is M bits, each of the X frequency domain ranges is a product of the first value and 1 / a, a is a positive integer greater than or equal to a first threshold value and less than or equal to a second threshold value; condition 5, if the bandwidth of the data unit is 1 / b of the first bandwidth, the first bandwidth includes c frequency domain ranges, each of the c frequency domain ranges is 20MHz, the first sub-information and / or the second sub-information includes c sub-information, the c sub-information and the c frequency domain ranges correspond one-to-one, each of the c sub-information is X*M / c bits, b is a positive integer greater than or equal to a third threshold value, the third threshold value is greater than the second threshold value, and c is a ratio of the bandwidth of the data unit to 20MHz; or, condition 6, if the bandwidth of the data unit is equal to Y frequency domain ranges, the first frequency domain range and / or the second frequency domain range includes Y frequency domain ranges, the first sub-information and / or the second sub-information includes Y sub-information, the Y sub-information and the Y frequency domain ranges correspond one-to-one, each of the Y sub-information is M bits, each of the Y frequency domain ranges is the first value, and Y is a positive integer less than X.

[0338] For condition 3, it is to be explained that, if the first bandwidth only includes the first frequency domain range, the first frequency domain range includes X frequency domain ranges, and the first sub-information includes X sub-information; if the first bandwidth only includes the second frequency domain range, the second frequency domain range includes X frequency domain ranges, and the second sub-information includes X sub-information; if the first bandwidth includes the first frequency domain range and the second frequency domain range, the first frequency domain range and the second frequency domain range together include X frequency domain ranges, and the first sub-information and the second sub-information together include X sub-information. Exemplarily, in combination with FIG. 15, the first bandwidth is 320 MHz, and the first frequency domain range and the second frequency domain range together include 4 frequency domain ranges, that is, the first bandwidth includes 4 frequency domain ranges, and the first sub-information and the second sub-information together include four sub-information.

[0339] The first value is understood as the bandwidth corresponding to each of the X frequency domain ranges. Exemplarily, in combination with FIG. 15, X is 4, and the first bandwidth is 320 MHz, and then the first value is 80 MHz, that is, each of the 4 frequency domain ranges is 80 MHz. Each of the X sub-information is M bits, and M may be 2, etc.

[0340] In condition 3, for each of the X frequency domain ranges, it is indicated by X bits that the RUs in the frequency domain range are continuous RUs, or it is indicated that the RUs in the frequency domain range are discrete RUs and the discrete bandwidth of the discrete RUs is indicated.

[0341] For condition 4, the first threshold and the second threshold are preset positive integers, and the first threshold is less than or equal to the second threshold. The number of frequency domain ranges included in the bandwidth of the data unit in condition 4 is X, which is the same as the number of frequency domain ranges included in the first bandwidth in condition 3, but the bandwidth of each frequency domain range included in the bandwidth of the data unit is less than the bandwidth of each frequency domain range included in the first bandwidth. The number of bits corresponding to each sub-information in condition 4 is the same as the number of bits corresponding to each sub-information in condition 3.

[0342] Exemplarily, in the case that the first bandwidth is 320 MHz, the first threshold can be 2, the second threshold can be 4, and 1 / a can be 1 / 2 or 1 / 4. In the case that 1 / a is 1 / 2, the bandwidth of the data bandwidth is 160 MHz, and then the bandwidth corresponding to each frequency domain range is the ratio of 160 to X, or the bandwidth corresponding to each frequency domain range is the product of the first value in condition 3 and 1 / a. For example, as shown in FIG. 16, X is 4, and M is 2, and then each of the 4 frequency domain ranges is 40 MHz, and each of the X sub-information is still 2 bits. In the case that 1 / a is 1 / 4, the bandwidth of the data bandwidth is 80 MHz, and then the bandwidth corresponding to each frequency domain range is the ratio of 80 to X, or the bandwidth corresponding to each frequency domain range is the product of the first value in condition 3 and 1 / a. For example, X is 4, and then each of the 4 frequency domain ranges is 20 MHz.

[0343] It can be understood that, since the subchannel is 20MHz, each of the X frequency domain ranges is greater than or equal to 20MHz, i.e., 1 / a is not less than 1 / 4.

[0344] Similarly, in the case where the first bandwidth is 160MHz, the first threshold value can be 2, and 1 / a can be 1 / 2. The bandwidth of the data unit is 80MHz, and the bandwidth corresponding to each frequency domain range is the ratio of 80MHz to X, or the bandwidth corresponding to each frequency domain range is the product of the first value in condition 3 and 1 / a. For example, X is 4, and each of the 4 frequency domain ranges is 20MHz.

[0345] Since the subchannel is 20MHz, each of the X frequency domain ranges is greater than or equal to 20MHz, i.e., 1 / a is not less than 1 / 2.

[0346] In condition 4, for each of the X frequency domain ranges, it is indicated by M bits that the RUs in the frequency domain range are continuous RUs or that the RUs in the frequency domain range are discrete RUs and the discrete bandwidth of the discrete RUs. However, the bandwidth corresponding to each of the X frequency domain ranges is the ratio of the bandwidth of the data unit to X or the product of the first value and 1 / a.

[0347] For condition 5, since the subchannel is 20MHz, each of the frequency domain ranges is greater than or equal to 20MHz. Then, if the ratio of the bandwidth of the data unit to X is less than or equal to 20MHz as the bandwidth of the data unit decreases, each of the frequency domain ranges in the data unit is 20MHz. Correspondingly, the number of frequency domain ranges included in the bandwidth of the data unit is the ratio of the bandwidth of the data unit to 20MHz, i.e., c, c is less than X. And the first sub-information and / or the second sub-information includes c sub-information.

[0348] Exemplarily, if the first bandwidth is 320MHz, the third threshold value can be 8, and b can be 8 or 16.

[0349] When b is 8, the bandwidth of the data unit is 40MHz. The bandwidth of the frequency domain range included in the bandwidth of the data unit is 20MHz, the bandwidth of the data unit includes 2 frequency domain ranges, and the first sub-information and / or the second sub-information includes 2 sub-information. For example, as shown in FIG. 17, M is 4, and X is 2, each of the 2 sub-information is 4 bits.

[0350] When b is 16, the bandwidth of the data unit is 20MHz. The bandwidth of the data unit includes a frequency domain range with a bandwidth of 20MHz, the bandwidth of the data unit includes one frequency domain range, and the first sub-information and / or the second sub-information includes one sub-information. M is 4 and X is 2, and each of the one sub-information is 8 bits.

[0351] In condition 5, compared with condition 3, each frequency domain range is equal to 20MHz, the total number of bits included in the second information is unchanged, but the number of bits corresponding to the sub-information for indicating each frequency domain range is increased.

[0352] For condition 6, on the basis of condition 3, part of the M×X bits in condition 3 can be reserved or used to indicate other information.

[0353] Wherein, if the bandwidth of the data unit only includes the first frequency domain range, the first frequency domain range includes Y frequency domain ranges, and the first sub-information includes Y sub-information; if the bandwidth of the data unit only includes the second frequency domain range, the second frequency domain range includes Y frequency domain ranges, and the second sub-information includes Y sub-information; if the bandwidth of the data unit includes the first frequency domain range and the second frequency domain range, the first frequency domain range and the second frequency domain range together include Y frequency domain ranges, and the first sub-information and the second sub-information together include Y sub-information.

[0354] Exemplarily, as shown in FIG. 18, assuming that the first bandwidth is 320MHz, the bandwidth of the data unit is 160MHz, and X is 4, then Y is 2, 2 sub-information occupies 4 bits, and the remaining 4 bits can be reserved.

[0355] Or, assuming that the first bandwidth is 320MHz, the bandwidth of the data unit is 80MHz, and X is 4, then Y is 1, 1 sub-information occupies 2 bits, and the remaining 6 bits can be reserved.

[0356] For the remaining bits, the number and distribution manner of the discrete bandwidths of the discrete RUs in the second frequency domain range can be indicated. For example, assuming that the second frequency domain range is 80MHz, and assuming that the second sub-information indicates that the discrete bandwidths of the discrete RUs in the second frequency domain range are 20MHz, the remaining bits can be used to indicate that the discrete bandwidths of the discrete RUs in the second frequency domain range are 20MHz+20MHz+20MHz+20MHz; or, assuming that the second frequency domain range is 80MHz, and assuming that the second sub-information indicates that the discrete bandwidths of the discrete RUs in the second frequency domain range are 40MHz, the remaining bits can be used to indicate that the discrete bandwidths of the discrete RUs in the second frequency domain range are 40MHz+40MHz; or, assuming that the second frequency domain range is 80MHz, and assuming that the second sub-information indicates that the discrete bandwidths of the discrete RUs in the second frequency domain range are 20MHz+40MHz, the remaining bits can be used to indicate that the discrete bandwidths of the discrete RUs in the second frequency domain range are 20MHz+20MHz+40MHz, and so on.

[0357] In addition to the above conditions 3 to 6, optionally, the meaning of each sub-information in the first sub-information and / or each sub-information in the second sub-information can change with the bandwidth of the data unit. For example, when the bandwidth of the data unit is 320MHz, and each frequency domain range is 80MHz, each sub-information corresponds to 80MHz, for example, 01 indicates that the RUs in the one frequency domain range are discrete RUs, and the discrete bandwidths of the discrete RUs in the one frequency domain range are 40MHz; when the bandwidth of the data unit is 80MHz, and one frequency domain range is 80MHz, one sub-information corresponds to 80MHz, and 01 can indicate that the RUs in the one frequency domain range are discrete RUs, and the discrete bandwidths of the discrete RUs in the one frequency domain range are 80MHz.

[0358] In Form Two, optionally, the second sub-information includes information for indicating that the RUs in the second frequency domain range are discrete RUs, and information for indicating the discrete bandwidths of the discrete RUs in the second frequency domain range.

[0359] In this embodiment, the first sub-information includes information for indicating that the RUs in the first frequency domain range are continuous RUs. For example, the information for indicating that the RUs in the first frequency domain range are continuous RUs can be 1 bit. And / or, the information for indicating that the RUs in the second frequency domain range are discrete RUs can be 1 bit. For example, 0 is used to indicate continuous RUs, and 1 is used to indicate discrete RUs; or, 1 is used to indicate continuous RUs, and 0 is used to indicate discrete RUs. In addition, the information for indicating the discrete bandwidths of the discrete RUs in the second frequency domain range can be multiple bits.

[0360] Exemplarily, as shown in FIG. 19, where information A can be understood as information used for indicating the discrete bandwidth of the discrete RU in the second frequency domain range; information B can be understood as information used for indicating that the RU in the second frequency domain range is a discrete RU. The first sub-information is 1 bit, used for indicating that the RU in the first frequency domain range is a continuous RU. The second frequency domain range includes a second frequency domain range 21, a second frequency domain range 22, and a second frequency domain range 23. The second sub-information includes a second sub-information 21 corresponding to the second frequency domain range 21, a second sub-information 22 corresponding to the second frequency domain range 22, and a second sub-information 23 corresponding to the second frequency domain range 23. The second sub-information 21 includes 1 bit (1) used for indicating that the RU in the second frequency domain range 21 is a discrete RU, and 2 bits (01) used for indicating the discrete bandwidth of the RU in the second frequency domain range 21; the second sub-information 22 includes 1 bit (1) used for indicating that the RU in the second frequency domain range 22 is a discrete RU, and 2 bits (00) used for indicating the discrete bandwidth of the RU in the second frequency domain range 22; the second sub-information 23 includes 1 bit (1) used for indicating that the RU in the second frequency domain range 23 is a discrete RU, and 2 bits (10) used for indicating the discrete bandwidth of the RU in the second frequency domain range 23.

[0361] It can be seen that for each of the second frequency domain ranges, 1 bit is used to indicate that the RU in the frequency domain range is a discrete RU, and multiple bits are used to indicate the discrete bandwidth of the discrete RU in the frequency domain range.

[0362] Taking the information used for indicating the discrete bandwidth of the discrete RU in the second frequency domain range as 2 bits for example, the meaning of the 2 bits can be as shown in Table 17. 00 can represent that the discrete bandwidth of the discrete RU in one frequency domain range is the smaller one of the bandwidth of a data unit and 80 MHz; 01 can represent that the discrete bandwidth of the discrete RU in one frequency domain range is left 20 MHz + right 40 MHz; 10 can represent that the discrete bandwidth of the discrete RU in one frequency domain range is left 40 MHz + right 20 MHz; and 11 can be reserved, or can also be used to indicate that the discrete bandwidth of the discrete RU in one frequency domain range is 40 MHz + 40 MHz, etc.

[0363] Table 17

[0364] It should be understood that Table 17 is merely an example, the 2 bits therein can be replaced by more bits or less bits, for example, 3 bits, and in the case of being replaced by more bits, the 3 bits indicated can also be 20MHz+20MHz+40MHz or 20MHz+20MHz+20MHz+20MHz, etc. for the discrete bandwidth of the discrete RU in one frequency domain range; or, the meanings of the various 2 bits therein can also be replaced by other meanings, for example, 11 is used to indicate that the discrete bandwidth of the discrete RU in one frequency domain range is 20MHz+20MHz+40MHz, etc.; or, the meanings of the respective 2 bits can also be interchanged, for example, 01 can represent that the discrete bandwidth of the discrete RU in one frequency domain range is the smaller one of the bandwidth of the data unit and 80MHz; 11 can represent that the discrete bandwidth of the discrete RU in one frequency domain range is left 20MHz+right 40MHz, etc. The embodiments of the present application do not make specific limitations in this regard.

[0365] It should be noted that, for one frequency domain range, left discrete bandwidth 1+right discrete bandwidth 2 can represent that when the first continuous RU is in the left half (or front half) of the one frequency domain range, the discrete bandwidth corresponding to the first continuous RU is the discrete bandwidth 1; when the first continuous RU is in the right half (or rear half) of the one frequency domain range, the discrete bandwidth corresponding to the first continuous RU is the discrete bandwidth 2. The left half (or front half) can refer to the half of the frequency domain range located at the smaller frequency position, and the right half (or rear half) can refer to the other half of the frequency domain range located at the larger frequency position.

[0366] Exemplarily, left 20MHz+right 40MHz can represent that when the first continuous RU is in the left 40MHz of the frequency domain range of 80MHz, the discrete bandwidth corresponding to the first continuous RU is 20MHz; when the first continuous RU is in the right 40MHz of the frequency domain range of 80MHz, the discrete bandwidth corresponding to the first continuous RU is 40MHz.

[0367] Left 40MHz+right 20MHz can represent that when the first continuous RU is in the left 40MHz of the frequency domain range of 80MHz, the discrete bandwidth corresponding to the first continuous RU is 40MHz; when the first continuous RU is in the right 40MHz of the frequency domain range of 80MHz, the discrete bandwidth corresponding to the first continuous RU is 20MHz.

[0368] It can be seen from Table 17 that if each sub-information is 2 bits, in Form I, the multiple 2 bits can include the first sub-information and the second sub-information, i.e., the 2 bits shown in Tables 8 to 11 all include the first sub-information and the second sub-information; in Form II, the multiple 2 bits include the second sub-information, i.e., the multiple 2 bits shown in Table 17 are the second sub-information. That is, in Form II, each 2 bit can be used to indicate a discrete bandwidth.

[0369] In Form III, the first sub-information includes information used to indicate that the RUs in the first frequency domain range are continuous RUs and puncturing state information used to indicate N1 sub-channels included in the first frequency domain range, N1 being a positive integer; and / or, the second sub-information includes information used to indicate that the RUs in the second frequency domain range are discrete RUs and puncturing state information used to indicate N2 sub-channels included in the second frequency domain range, N2 being a positive integer.

[0370] The puncturing state information of the N1 sub-channels can be understood as information used to indicate whether each of the N1 sub-channels is punctured; the puncturing state information of the N2 sub-channels can be understood as information used to indicate whether each of the N2 sub-channels is punctured. The information used to indicate that the RUs in the first frequency domain range are continuous RUs can be 1 bit, and the information used to indicate that all the N1 sub-channels included in the first frequency domain range are not punctured can be a bit map with a bit number of N1; the information used to indicate that the RUs in the second frequency domain range are discrete RUs can be 1 bit, and the information used to indicate whether the N2 sub-channels included in the second frequency domain range are punctured can be a bit map with a bit number of N2. Each bit in the bit map corresponds to 1 sub-channel and is used to represent whether the sub-channel is punctured. For example, 1 can represent punctured, and 0 represents not punctured; or, 1 can represent not punctured, and 0 represents punctured.

[0371] Exemplarily, as shown in FIG. 20, where information B can be understood as: information for indicating that the RU in the first frequency domain range is a continuous RU, and information for indicating the discrete bandwidth of the discrete RU in the second frequency domain range; information A can be understood as: information for indicating that none of the N1 subchannels included in the first frequency domain range is punctured, and information for indicating whether the N2 subchannels included in the second frequency domain range are punctured. The first sub-information includes 1 bit (0) for indicating that the RU in the first frequency domain range is a continuous RU, and a bit bitmap (1111) for indicating that none of the 4 subchannels in the first frequency domain range is punctured. The second frequency domain range includes the second frequency domain range 24, the second frequency domain range 25, and the second frequency domain range 26. The second sub-information includes the second sub-information 24 corresponding to the second frequency domain range 24, the second sub-information 25 corresponding to the second frequency domain range 25, and the second sub-information 26 corresponding to the second frequency domain range 26. The second sub-information 24 includes 1 bit (1) for indicating that the RU in the second frequency domain range 24 is a discrete RU, and a bit bitmap (1011) for indicating that one of the 4 subchannels in the second frequency domain range 24 is punctured and three are not punctured; the second sub-information 25 includes 1 bit (1) for indicating that the RU in the second frequency domain range 25 is a discrete RU, and a bit bitmap (1111) for indicating that none of the 4 subchannels in the second frequency domain range 25 is punctured; the second sub-information 26 includes 1 bit (1) for indicating that the RU in the second frequency domain range 26 is a discrete RU, and a bit bitmap (0011) for indicating that 2 of the 4 subchannels in the second frequency domain range 26 are punctured and 2 are not punctured.

[0372] The first passes the information for indicating whether the N2 subchannels included in the second frequency domain range are punctured, and the discrete bandwidth of the discrete RU in the second frequency domain range can be determined. Taking an example that each of the second frequency domain ranges includes 80MHz as an example.

[0373] Optionally, each of the second frequency domain ranges includes 4 subchannels, and the second sub-information satisfies one or more of the following conditions:

[0374] The first, if the 4 subchannels are not punctured, the discrete bandwidth of the discrete RU in each of the second frequency domain ranges is the total bandwidth covered by the 4 subchannels.

[0375] The second, if the 4 subchannels include 3 adjacent subchannels that are not punctured and one punctured subchannel, the discrete bandwidth of the discrete RU in each of the second frequency domain ranges includes a fifth discrete bandwidth and a sixth discrete bandwidth, the fifth discrete bandwidth is the bandwidth covered by one of the adjacent three subchannels adjacent to the punctured subchannel, and the sixth discrete bandwidth is the bandwidth covered by the remaining two of the adjacent three subchannels.

[0376] Item 3, if the 4 sub-channels include one punctured sub-channel, one non-punctured sub-channel located at one side of the one sub-channel, and two non-punctured sub-channels located at the other side of the one sub-channel, the discrete bandwidth of the discrete RU in each frequency domain range includes the bandwidth covered by the one non-punctured sub-channel, and the bandwidth covered by the two non-punctured sub-channels.

[0377] Item 4, if the 4 sub-channels include two adjacent punctured sub-channels and two adjacent non-punctured sub-channels, the discrete bandwidth of the discrete RU in each frequency domain range includes the bandwidth covered by the two adjacent non-punctured sub-channels.

[0378] Item 5, if the 4 sub-channels include two non-adjacent non-punctured sub-channels, the discrete bandwidth of the discrete RU in each frequency domain range includes a seventh discrete bandwidth and an eighth discrete bandwidth, the seventh discrete bandwidth is the bandwidth covered by one of the two non-punctured sub-channels, and the eighth discrete bandwidth is the bandwidth covered by the other of the two non-punctured sub-channels.

[0379] Item 6, if the 4 sub-channels include one non-punctured sub-channel, the discrete bandwidth of the discrete RU in each frequency domain range includes the bandwidth covered by the one non-punctured sub-channel.

[0380] For Item 1, since the larger the discrete bandwidth corresponding to the first contiguous RU is, the larger the power of the first device for sending the data unit can be, when none of the 4 sub-channels is punctured, the discrete bandwidth of the discrete RU in each frequency domain range is the total bandwidth covered by the 4 sub-channels, i.e., 80MHz. If the first contiguous RU is in the 4 sub-channels, the discrete bandwidth corresponding to the first contiguous RU is 80MHz. Exemplarily, in combination with the second frequency domain range 25 in FIG. 20, the discrete bandwidth of the discrete RU in the second frequency domain range 25 is 80MHz.

[0381] For Item 2, since each frequency domain range includes 4 sub-channels, when three adjacent sub-channels are not punctured, one of the three adjacent sub-channels is located in the first half of the each frequency domain range, and the other two sub-channels are located in the second half of the each frequency domain range; or, one of the three adjacent sub-channels is located in the second half of the each frequency domain range, and the other two sub-channels are located in the first half of the each frequency domain range. Since the three adjacent sub-channels are not completely located in the first half or the second half of the each frequency domain range, the discrete bandwidth of the discrete RU in the each frequency domain range includes two discrete bandwidths. The bandwidth covered by the remaining two sub-channels can be understood as the total bandwidth covered by the remaining two sub-channels, so that the discrete bandwidth of the discrete RU in the each frequency domain range can be larger.

[0382] For example, as shown in FIG. 21, one of the three non-punctured subchannels is in the first half of each of the frequency domain ranges. Therefore, the discrete bandwidth of the discrete RU in each of the frequency domain ranges includes 20MHz corresponding to the one subchannel in the first half of each of the frequency domain ranges; and the discrete bandwidth of the discrete RU in each of the frequency domain ranges further includes 40MHz corresponding to the remaining two subchannels in the second half of each of the frequency domain ranges.

[0383] In addition, if the first contiguous RU is in one of the two non-punctured subchannels adjacent to the punctured subchannel, the discrete bandwidth corresponding to the first contiguous RU is the bandwidth of the one non-punctured subchannel; and if the first contiguous RU is in the remaining one non-punctured subchannel, the discrete bandwidth corresponding to the first contiguous RU is the total bandwidth of the two non-punctured subchannels.

[0384] For the third item, if one punctured subchannel separates three non-punctured subchannels, the discrete bandwidth of the discrete RU in each of the frequency domain ranges is two discrete bandwidths. For example, as shown in the second frequency domain range 24 in FIG. 20, the punctured subchannel separates one of the three non-punctured subchannels in the first half of the second frequency domain range 24, and separates the other two non-punctured subchannels in the second half of the second frequency domain range 24. Therefore, the discrete bandwidth of the discrete RU in each of the frequency domain ranges includes two discrete bandwidths, i.e., 20MHz and 40MHz.

[0385] In addition, if the first contiguous RU is in one of the two non-punctured subchannels adjacent to the punctured subchannel, the discrete bandwidth corresponding to the first contiguous RU is the bandwidth of the one non-punctured subchannel; and if the first contiguous RU is in the remaining one non-punctured subchannel, the discrete bandwidth corresponding to the first contiguous RU is the total bandwidth of the two non-punctured subchannels.

[0386] For the fourth item, the bandwidth of the two adjacent non-punctured subchannels can be understood as the total bandwidth of the two adjacent non-punctured subchannels. For example, as shown in the second frequency domain range 26 in FIG. 20, the two non-punctured subchannels are in the second half of the second frequency domain range 24, and the discrete bandwidth of the discrete RU in each of the frequency domain ranges is 40MHz.

[0387] In addition, if the first contiguous RU is in one of the two non-punctured subchannels adjacent to the punctured subchannel, the discrete bandwidth corresponding to the first contiguous RU is the bandwidth of the one non-punctured subchannel; and if the first contiguous RU is in the remaining one non-punctured subchannel, the discrete bandwidth corresponding to the first contiguous RU is the total bandwidth of the two non-punctured subchannels.

[0388] For item 5, if the 4 sub-channels include two non-adjacent non-punctured sub-channels, it is indicated that the 4 sub-channels further include two non-adjacent punctured sub-channels, such that one of the two non-adjacent non-punctured sub-channels is located in the first half of each of the frequency domain ranges, and the other is located in the second half of each of the frequency domain ranges. Therefore, the discrete bandwidth of the discrete RU in each of the frequency domain ranges includes two discrete bandwidths. For example, as shown in (a) or (b) of FIG. 22, the discrete bandwidth of the discrete RU in each of the frequency domain ranges is 20MHz+20MHz.

[0389] In addition, if the first continuous RU is located in one non-punctured sub-channel, the discrete bandwidth corresponding to the first continuous RU is the bandwidth covered by the one sub-channel. If the first continuous RU is located in another non-punctured sub-channel, the discrete bandwidth corresponding to the first continuous RU is the bandwidth covered by the other sub-channel.

[0390] As can be seen from the above 5 items, when there are multiple non-punctured sub-channels located in the first half or the second half of each of the frequency domain ranges, the discrete bandwidth of the discrete RU in each of the frequency domain ranges includes the total bandwidth covered by the multiple non-punctured sub-channels. In this way, the discrete bandwidth of the discrete RU in each of the frequency domain ranges is larger.

[0391] For item 6, if only one non-punctured sub-channel is included in one frequency domain range, the discrete bandwidth of the discrete RU in the frequency domain range is the bandwidth covered by the one non-punctured sub-channel. That is, when the first continuous RU is located in the one frequency domain range, the discrete bandwidth corresponding to the first continuous RU is the bandwidth covered by the one non-punctured sub-channel.

[0392] It should be noted that in the case where each of the frequency domain ranges is larger than 80MHz or smaller than 80MHz, for example, 40MHz, 160MHz, etc., the relationship between the discrete bandwidth of the discrete RU in each of the frequency domain ranges and the puncturing of the sub-channels included in each of the frequency domain ranges is similar to the above 5 items, and can be referred to the description above, which will not be described one by one here.

[0393] The above describes the correspondence between the puncturing state information and the discrete bandwidth, i.e., the manner in which the first device determines the discrete bandwidth of the discrete RU in each of the frequency domain ranges in the second frequency domain range according to the puncturing state information. In some possible implementation, in the case where the first device determines the discrete bandwidth of the discrete RU in one of the frequency domain ranges in the second frequency domain range, the puncturing state information corresponding to the one frequency domain range can not be determined. That is, the discrete bandwidth of the discrete RU in the one frequency domain range indicated by the second information can not correspond to one puncturing state, or the discrete bandwidth of the discrete RU in the one frequency domain range indicated by the second information can correspond to multiple puncturing states.

[0394] Exemplarily, assuming that the discrete bandwidth of the discrete RU in one of the frequency domain ranges in the second frequency domain range is left 20 MHz + right 40 MHz, the puncturing state information corresponding to the one of the frequency domain ranges can be 1111, i.e., none of the 4 sub-channels is punctured, and correspondingly, the actual discrete bandwidth of the discrete RU in the one of the frequency domain ranges in the second frequency domain range is 20 MHz + 20 MHz + 40 MHz; or the puncturing state information corresponding to the one of the frequency domain ranges can be 1011 or 0111, i.e., one of the sub-channels in the first half of the one of the frequency domain ranges is punctured, and correspondingly, the actual discrete bandwidth of the discrete RU in the one of the frequency domain ranges in the second frequency domain range is 20 MHz + 40 MHz. Similarly, when the discrete bandwidth of the discrete RU in the one of the frequency domain ranges in the second frequency domain range is left 40 MHz + right 20 MHz, the second half of the one of the frequency domain ranges can have one of the sub-channels punctured, or all of the 4 sub-channels in the one of the frequency domain ranges can be punctured. Or, when the discrete bandwidth of the discrete RU in the one of the frequency domain ranges in the second frequency domain range is 40 MHz, it can represent that 2 of the sub-channels in the first half of the one of the frequency domain ranges or 2 of the sub-channels in the second half of the one of the frequency domain ranges are punctured, or all of the 4 sub-channels in the one of the frequency domain ranges can be punctured.

[0395] Based on the above cases, the second information can indicate the discrete bandwidth of the discrete RU in the one of the frequency domain ranges in the second frequency domain range and the puncturing state information through one information (or also can be referred to as one entry), for example, the second information includes 110, 110 represents that the RU in the one of the frequency domain ranges is a discrete RU, and the discrete bandwidth of the discrete RU in the one of the frequency domain ranges is 20 MHz + 20 MHz + 40 MHz, and 20 MHz + 20 MHz + 40 MHz can also represent that all of the 4 sub-channels in the one of the frequency domain ranges are not punctured. Or, the second information is used to indicate 20 MHz + X + 40 MHz, where X represents puncturing, i.e., 20 MHz + X + 40 MHz represents that the second sub-channel in the one of the frequency domain ranges is punctured. Or, the second information is used to indicate X + 20 MHz + 40 MHz, where X represents puncturing, i.e., the first sub-channel in the one of the frequency domain ranges is punctured. Or, the second information is used to indicate X + X + 40 MHz, where X represents puncturing, i.e., the first sub-channel and the second sub-channel in the one of the frequency domain ranges are punctured. Or, the second information is used to indicate 20 MHz + 20 MHz + X, where X represents puncturing, i.e., the third sub-channel and the fourth sub-channel in the one of the frequency domain ranges are punctured.

[0396] wherein the first sub-channel, the second sub-channel, the third sub-channel, and the fourth sub-channel refer to the 4 sub-channels arranged in ascending order of frequency.

[0397] On the basis of the above-mentioned embodiments, if the discrete bandwidth of the discrete RU in each frequency domain in the second frequency domain range is a multiple of the discrete bandwidth in each of the second frequency domain range, the trigger frame can indicate the discrete bandwidth in the following manner.

[0398] Optionally, the trigger frame further comprises third information, the third information being used to indicate whether the discrete RU in the second frequency domain range comprises a ninth discrete bandwidth, the ninth discrete bandwidth being S times of each of the second frequency domain range, S being an integer greater than 1; or, the information used to indicate that the RU in the second frequency domain range is a discrete RU is further used to indicate that the discrete bandwidth of the discrete RU in the second frequency domain range is the ninth discrete bandwidth.

[0399] Wherein, S can be 2 or 4, etc. The third information can be one or more bits, or can also be other identifiers. For example, the third information can be 1 bit, etc., 1 indicating that the discrete RU in the second frequency domain range comprises the ninth discrete bandwidth, 0 indicating that the discrete RU in the second frequency domain range does not comprise the ninth discrete bandwidth; or, 0 indicating that the discrete RU in the second frequency domain range comprises the ninth discrete bandwidth, 1 indicating that the discrete bandwidth of the discrete RU in the second frequency domain range does not comprise the ninth discrete bandwidth, etc. Exemplarily, the third information can also be 2 bits, the 2 bits indicating that the discrete bandwidth of which of the second frequency domain range corresponds to the ninth discrete bandwidth. For example, 00 can indicate that the discrete bandwidth of the discrete RU in the second frequency domain range does not comprise the ninth discrete bandwidth; 11 can indicate that the discrete bandwidth of the discrete RU in the second frequency domain range comprises the ninth discrete bandwidth, and the discrete bandwidth of a plurality of frequency domain ranges in the left half (the frequency domain range located at a lower frequency position) is the ninth discrete bandwidth; 10 can indicate that the discrete bandwidth of the discrete RU in the second frequency domain range comprises the ninth discrete bandwidth, and the discrete bandwidth of a plurality of frequency domain ranges in the right half (the frequency domain range located at a higher frequency position) is the ninth discrete bandwidth.

[0400] Taking form three as an example, as shown in FIG. 23, in the case that there is no punctured subchannel in each of the two adjacent frequency domain ranges, the discrete bandwidth of the discrete RU in the two adjacent frequency domain ranges can be the sum of the two adjacent frequency domain ranges. For example, each frequency domain range is 80MHz, and the discrete bandwidth of the discrete RU in the two adjacent frequency domain ranges can be 160MHz. The third information can be 1 bit, i.e., the third information 1, when the first device reads the third information 1, it can be determined according to the third information 1 that the discrete bandwidth of the discrete RU in the second frequency domain range is 160MHz. The third information can also be 2 bits, i.e., the third information 2. The two bits 11 can indicate that the discrete bandwidth of the discrete RU in the second frequency domain range includes 160MHz (i.e., the ninth discrete bandwidth), and 11 can also indicate that the discrete bandwidth of the discrete RU in the two frequency domain ranges in the latter half is 160MHz. In this way, when the first device reads the third information 2, it can be determined according to the third information 2 that the discrete bandwidth of the discrete RU in the second frequency domain range 25 and the second frequency domain range 27 is 160MHz. Compared with 1 bit, when the third information is multiple bits, the ninth discrete bandwidth corresponding to multiple frequency domain ranges can also be indicated.

[0401] On the basis of the above embodiment, if the third information is one bit, the third information can be carried in the user information field. Exemplarily, the 1 bit can be a reserved field in the user information field, or can also be an uplink forward error correction coding type field, or can also be an UL dual-carrier modulation (DCM) field, a spatial stream (SS) allocation field, etc.

[0402] If the third information is multiple bits, the third information can be carried in the user information field, the common information field or the special user information field.

[0403] In the case that the information for indicating that the RU in the second frequency domain range is a discrete RU is also used to indicate that the discrete bandwidth of the discrete RU in the second frequency domain range is the ninth discrete bandwidth, the information for indicating that the RU in the second frequency domain range is a discrete RU can be multiple bits.

[0404] Taking Form Three as an example, as shown in FIG. 24, it is assumed that each frequency domain range is 80 MHz, and the ninth discrete bandwidth is 160 MHz. The first sub-information includes information for indicating that the RU in the first frequency domain range is a continuous RU, which is 00; the information for indicating that the RU in the second frequency domain range 24 is a discrete RU in the second sub-information 24 is 10, and 10 further indicates that the discrete bandwidth of the RU in the second frequency domain range 24 is not 160 MHz; the information for indicating that the RU in the second frequency domain range 25 is a discrete RU in the second sub-information 25 is 11, and 11 further indicates that the discrete bandwidth of the RU in the second frequency domain range 25 is 160 MHz; the information for indicating that the RU in the second frequency domain range 26 is a discrete RU in the second sub-information 26 is 11, and 11 further indicates that the discrete bandwidth of the RU in the second frequency domain range 26 is 160 MHz.

[0405] It should be noted that FIG. 23 and FIG. 24 are only examples, and in the case of other forms of the second sub-information, the third information or the information for indicating that the RU in the second frequency domain range is a discrete RU can also refer to the description above, and will not be described herein again.

[0406] It should be further noted that in the case of the first sub-information and / or the second sub-information being Form One, the trigger frame can further include third information, which can refer to the description above. Alternatively, the second sub-information can be further used to indicate whether the discrete bandwidth of the discrete RU in the second frequency domain range includes the ninth discrete bandwidth. Similarly, the second sub-information can be multiple bits. For example, as shown in Table 12, in the case of 3 bits being 000, 001, 010, or 011, the discrete bandwidth corresponding to one frequency domain range is not 160 MHz, and in the case of 3 bits being 100, the discrete bandwidth corresponding to one frequency domain range is 160 MHz.

[0407] It should be noted that for Form Two and Form Three, the information for indicating that the RU in the first frequency domain range is a continuous RU included in the first sub-information and the information for indicating that the RU in the second frequency domain range is a discrete RU included in the second sub-information can also be understood as one bit map.

[0408] Optionally, the second information includes information for indicating that the RU in the first frequency domain range is a continuous RU and puncturing state information of N1 sub-channels included in the first frequency domain range, N1 being a positive integer; and / or, the second information includes information for indicating that the RU in the second frequency domain range is a discrete RU and puncturing state information of N2 sub-channels included in the second frequency domain range, N2 being a positive integer.

[0409] The puncturing status information of the N1 sub-channels can be understood as information indicating whether each of the N1 sub-channels is punctured or not. The puncturing status information of the N2 sub-channels can be understood as information indicating whether each of the N2 sub-channels is punctured or not. The information included in the second information indicating that the RUs in the first frequency domain range are continuous RUs and the information indicating that the RUs in the second frequency domain range are discrete RUs can be understood as a bit map. In combination with FIG. 23, the information B can be understood as a bit map 0111.

[0410] In addition, the puncturing status information of the N1 sub-channels can also be understood as a bit map. In combination with FIG. 23, the puncturing status information of the N1 sub-channels corresponding to the first frequency domain range is 1111. Similarly, the puncturing status information of the N2 sub-channels can also be understood as a bit map.

[0411] Alternatively, the second information includes information indicating that the RUs in the second frequency domain range are discrete RUs and information indicating the discrete bandwidths of the discrete RUs in the second frequency domain range.

[0412] The information included in the second information indicating that the RUs in the first frequency domain range are continuous RUs and the information indicating that the RUs in the second frequency domain range are discrete RUs can be understood as a bit map. For example, as shown in FIG. 19, the information B can be understood as a bit map 0111. In addition, the information indicating the discrete bandwidths of the discrete RUs in the second frequency domain range can be understood as one information or multiple information. When the information indicating the discrete bandwidths of the discrete RUs in the second frequency domain range is one information, the one information can be used to indicate the discrete bandwidths of the discrete RUs in each of the frequency domain ranges in the second frequency domain range, for example, the one information can be 01001011, etc. When the information indicating the discrete bandwidths of the discrete RUs in the second frequency domain range is multiple information, one of the multiple information can be used to indicate the discrete bandwidths of the discrete RUs in one of the frequency domain ranges in the second frequency domain range, that is, the multiple information corresponds to the multiple frequency domain ranges in the second frequency domain range one by one. For example, the multiple information is 01 and 11, the second frequency domain range includes a frequency domain range A and a frequency domain range B, then 01 can be used to indicate the discrete bandwidths of the discrete RUs in the frequency domain range A, and 11 can be used to indicate the discrete bandwidths of the discrete RUs in the frequency domain range B.

[0413] In the second case, the second information is one information, that is, the one information indicates both the content about the first frequency domain range and the content about the second frequency domain range.

[0414] Alternatively, it can also be understood that, in this case, the first device indicates, by one information (or one entry) in the trigger frame, that the RUs in the first frequency domain range are contiguous RUs in the one or more frequency domain ranges, and / or indicates that the RUs in the second frequency domain range are discrete RUs and the discrete bandwidths of the discrete RUs in the second frequency domain range.

[0415] The second information may, for example, be G bits, for example, 8 bits, etc. Assuming that the first frequency domain range and / or the second frequency domain range include X frequency domain ranges, and the total bandwidth corresponding to the X frequency domain ranges is a first bandwidth. If the first bandwidth only includes the first frequency domain range, the second information is used to indicate that each frequency domain range in the first frequency domain range is a contiguous RU; if the first bandwidth only includes the second frequency domain range, the second information is used to indicate that each frequency domain range in the second frequency domain range is a discrete RU, and is also used to indicate the discrete bandwidths of the discrete RUs in each frequency domain range in the second frequency domain range; if the first bandwidth includes the first frequency domain range and the second frequency domain range, the second information is used to indicate that each frequency domain range in the first frequency domain range is a contiguous RU, and is also used to indicate that each frequency domain range in the second frequency domain range is a discrete RU, and is further used to indicate the discrete bandwidths of the discrete RUs in each frequency domain range in the second frequency domain range.

[0416] Exemplarily, G is 8, as shown in Table 18, and each frequency domain range is 80 MHz. d1 rRU can represent that the RUs in the frequency domain range (d1) are contiguous RUs; d1 dRU can represent that the RUs in the frequency domain range (d2) are discrete RUs, and the discrete bandwidths of the discrete RUs in the frequency domain range (d2) are d2. (left 20 MHz + right 40 MHz) dRU can represent that the RUs in the frequency domain range are discrete RUs, and the discrete bandwidths of the discrete RUs in the frequency domain range are left 20 MHz + right 40 MHz.

[0417] 00000000 can represent that all the RUs in the whole 320MGz are contiguous RUs. 00000001 can represent that, in the order of frequency from low to high, the RUs in the first frequency domain range are contiguous RUs; the RUs in the second frequency domain range are discrete RUs, and the discrete bandwidth of the discrete RUs in the frequency domain range is 20MHz+right 40MHz; the RUs in the third frequency domain range are contiguous RUs; the RUs in the fourth frequency domain range are contiguous RUs. 00000011 can represent that, in the order of frequency from low to high, the RUs in the first frequency domain range are contiguous RUs; the RUs in the second frequency domain range are discrete RUs, and the discrete bandwidth of the discrete RUs in the frequency domain range is 80MHz; the RUs in the third frequency domain range are contiguous RUs; the RUs in the fourth frequency domain range are contiguous RUs. 00000111 can represent that, in the order of frequency from low to high, the RUs in the first frequency domain range are contiguous RUs; the RUs in the second frequency domain range are discrete RUs, and the discrete bandwidth of the discrete RUs in the frequency domain range is left 20MHz+right 40MHz; the RUs in the third frequency domain range are discrete RUs, and the discrete bandwidth of the discrete RUs in the frequency domain range is 160MHz; the RUs in the fourth frequency domain range are discrete RUs, and the discrete bandwidth of the discrete RUs in the frequency domain range is 160MHz. 00001111 can represent that all the RUs in the whole 320MGz are discrete RUs, and the discrete bandwidth of the RUs in the whole 320MGz is 320MHz.

[0418] Table 18

[0419] It should be noted that Table 18 is merely an example, and the number of bits of the second information can be greater or smaller; and the meaning corresponding to the second information can be other meanings, for example, 00000000 can also represent 80dRU+80dRU+80rRU+80rRU, etc.; and any bit value shown in Table 18 can also be other values, for example, 111111111 represents 320rRU, etc.

[0420] It should be understood that, in the case of a larger or smaller each frequency domain range, and / or, a greater or smaller number of frequency domain ranges, etc., the manner in which the second information indicates the frequency domain ranges is similar to Table 18, and reference can be made to the description above, which will not be repeated here.

[0421] Optionally, in case that the bandwidth of the data unit is less than the first bandwidth, for example, the bandwidth of the data unit includes x1 frequency domain ranges, x1 is less than X, the first frequency domain range and / or the second frequency domain range includes x1 frequency domain ranges. The second information can correspond to indicate the first x1 frequency domain ranges in the X frequency domain ranges. For example, in combination with Table 18, assuming that the bandwidth of the data unit is 160MHz, the second information corresponds to indicate the first 2 frequency domain ranges, 00000000 can represent that the RUs in the entire 160MGz are all continuous RUs. 00000001 can represent that, in the order from low to high in frequency, the RU in the first frequency domain range is a continuous RU; the RU in the second frequency domain range is a discrete RU, and the discrete bandwidth of the discrete RU in the frequency domain range is 20MHz+right 40MHz; and so on.

[0422] Further, the embodiments of the present application also provide an information transmission method 1000. The method 1000 can be applied to the communication system 400. Wherein, the first device can be a station, for example, can be the station 430 and / or the station 440 in the communication system 400, etc., and the second device can be an access point, for example, can be the access point 410 in the communication system 400. The method 1000 includes the following steps:

[0423] S1001, the second device sends a trigger frame to the first device, the trigger frame includes first information and fourth information, the first information is used to indicate the first continuous RU, the fourth information is used to indicate that the RU in the third frequency domain range is a continuous RU, and / or, the RU in the fourth frequency domain range is a discrete RU and the discrete bandwidth of the discrete RU in the fourth frequency domain range; wherein, the first information is carried in a user information field, and the fourth information is carried in any one of the following: a user information field; a user information list field; or, a user information field and a common information field. Correspondingly, the first device receives the trigger frame from the second device. The user information field can be, for example, a user information 2 field to a user information E field, etc.

[0424] Wherein, the third frequency domain range is similar to the first frequency domain range in the method 900, and the fourth frequency domain range is similar to the second frequency domain range in the method 900, which can be referred to the description above, and will not be repeated here.

[0425] It can be understood that the trigger frame includes the PS160 field and the resource unit allocation field; the resource unit allocation field includes 8 bits, i.e., B0, B1, B2, B3, B4, B5, B6 and B7. Each of B0 to B7 can be 1 bit. Among them, the PS160 field can be used to indicate whether the first continuous RU is in the primary 160MHz or the secondary 160MHz; B0 can be used to indicate which 80MHz in the 160MHz the first continuous RU is in. Therefore, in the case that the bandwidth of the data unit is less than or equal to 80MHz, the PS160 field in the trigger frame does not need to indicate whether the first continuous RU is in the primary 160MHz or the secondary 160MHz; and B0 does not need to indicate which 80MHz in the 160MHz the first continuous RU is in. For example, the PS160 field and B0 can be 00, etc.

[0426] In the case that the bandwidth of the data unit is less than or equal to 80MHz, the fourth information can be carried in the user information field, such as the PS160 field and B0. The fourth information can be L bits, etc., where L is a positive integer.

[0427] At this time, the fourth information is similar to the first sub-information and / or the second sub-information in form one in the method 900, and can refer to the description above.

[0428] Taking L as 2 as an example, the meaning of 2 bits can be as shown in Table 19. 00 can represent that the RU in one frequency domain range is a continuous RU; 01 can represent that the RU in one frequency domain range is a discrete RU, and the discrete bandwidth of the discrete RU in one frequency domain range is 20MHz; 10 can represent that the RU in one frequency domain range is a discrete RU, and the discrete bandwidth of the discrete RU in one frequency domain range is 40MHz; and 11 can represent that the RU in one frequency domain range is a discrete RU, and the discrete bandwidth of the discrete RU in one frequency domain range is 80MHz.

[0429] It should be noted that Table 19 is only an example, and the meanings corresponding to 00, 01, 10 and 11 can also be interchanged, for example, 11 can represent that the RU in one frequency domain range is a continuous RU; 00 can represent that the RU in one frequency domain range is a discrete RU, and the discrete bandwidth of the discrete RU in one frequency domain range is 40MHz, etc. The present application does not make a specific limitation on this.

[0430] Table 19

[0431] In the case that the bandwidth of the data unit is greater than 80MHz, e.g. equal to 160MHz, the fourth information can comprise information 4 for indicating that the RUs in the third frequency range are contiguous RUs and / or the RUs in the fourth frequency range are discrete RUs, and information 5 for indicating the discrete bandwidth of the discrete RUs in the fourth frequency range. The information 4 can be carried in the common information field or the special user information field, and the information 5 can be carried in the user information field, e.g. in the resource unit allocation field in the user information 2 field to the user information E field.

[0432] wherein the information 4 is similar to the information B in the method 900, e.g. can be a bitmap, each bit in the bitmap is for indicating that the RUs in one frequency range are discrete RUs or contiguous RUs, and the information 5 is similar to the second sub-information in the second form in the method 900, which can be referred to the description above, and will not be repeated here.

[0433] Exemplarily, the trigger frame can not support indicating MRU, and / or not support indicating partial size of dRU, e.g. not support 26-tone dRU, so that part of the subfields in B1 to B7 can be used for indicating the information 5.

[0434] Further, optionally, in the case that the bandwidth of the data unit is greater than 80MHz, the first information can also be carried in the user information field, e.g. in the resource unit allocation field in the user information 2 field to the user information E field. That is, in this case, the first information and the fourth information can be understood as one information, i.e. the first information and the fourth information are both carried in B1 to B7. In this way, the information carried in B1 to B7 can be used for indicating any one or more of the following: the position of the first contiguous RU, the size of the first contiguous RU, the first contiguous RU being contiguous RU or discrete RU, or the discrete bandwidth corresponding to the first contiguous RU. Exemplarily, the information carried in B1 to B7 (i.e. the first information and the fourth information) can be 000, which indicates that the position and the size of the first contiguous RU is the first 26-tone RU, and indicates that the first contiguous RU is contiguous RU; 001 indicates that the position and the size of the first contiguous RU is the ninth 26-tone RU, and indicates that the discrete bandwidth corresponding to the first contiguous RU is 20MHz, etc.

[0435] It can be understood that in this case, the meaning of part of the subfields in B1 to B7 is equivalent to being assigned a new meaning, and the first device can determine whether the meaning of the part of the subfields is used for indicating the discrete bandwidth of the discrete RUs in the fourth frequency range through the information 4. For example, when the first device determines through the information 4 that the RUs in the fourth frequency range are discrete RUs, the first device can determine that the meaning of the part of the subfields is used for indicating the discrete bandwidth of the discrete RUs in the fourth frequency range.

[0436] Further, the fourth information can also include information 5, i.e., not including information 4, so that the fourth information can be carried in the resource unit allocation field and the PS 160 field.

[0437] In this case, the fourth information can also be L bits. The meaning of the L bits can be as shown in Table 19, or the meaning of the L bits can also be replaced by others, which is not limited here.

[0438] S1002, the first device transmits data on a second RU, the second RU being the first contiguous RU, or the second RU being a discrete RU mapped on a discrete bandwidth corresponding to the first contiguous RU on which the first contiguous RU is located. The first contiguous RU is determined according to the first information and the fourth information.

[0439] It should be understood that the implementation of S1002 is similar to that of S902, and the determination of the discrete bandwidth corresponding to the first contiguous RU is similar to the method 900, and the description can be referred to the description above, which will not be repeated here.

[0440] Through such an information transmission method, no additional overhead needs to be added in the trigger frame, which helps to allocate resource units to stations with less overhead.

[0441] It should be understood that in the embodiments of the present application, one of the first frequency domain ranges, each of the first frequency domain ranges, and one first frequency domain range represent the same meaning, and the three can be interchangeable; one of the second frequency domain ranges, each of the second frequency domain ranges, and one second frequency domain range represent the same meaning, and the three can be interchangeable, which is not limited in the present application.

[0442] It should also be understood that in the embodiments of the present application, various terms and English abbreviations, such as rRU, dRU, PPDU, DBW, etc., are exemplary examples given for convenience of description, and should not constitute any limitation on the present application. The present application does not exclude the possibility of defining other terms capable of achieving the same or similar functions in the existing or future protocols.

[0443] It should be noted that in the embodiments of the present application, one frequency domain range can be any one of 20MHz, 40MHz, 80MHz, 160MHz or 320MHz. And in the case of one frequency domain range being 80MHz, the trigger frame can further include information for indicating whether the discrete bandwidth corresponding to one frequency domain range is 160MHz, such as the third information above, and the trigger frame can further include information for indicating whether the discrete bandwidth corresponding to one frequency domain range is 320MHz, such as the fourth information above. And the embodiments of the present application are not limited to 160MHz and 320MHz, the trigger frame can also include information for indicating that the discrete bandwidth corresponding to one frequency domain range is other, and the implementation manners can be referred to the above, which will not be listed one by one here.

[0444] The information transmission method of the embodiments of the present application is described in detail above in combination with FIG. 9 to FIG. 24, and the information transmission apparatus of the embodiments of the present application is described in detail below in combination with FIG. 25 and FIG. 26. The information transmission apparatus includes modules or units for executing the corresponding parts of each of the above embodiments. The modules or units can be software, hardware or a combination of software and hardware. The information transmission apparatus is only briefly exemplified below, and for the details of the scheme implementation, the description of the foregoing method embodiments can be referred to, which will not be described here again.

[0445] FIG. 25 is a schematic block diagram of an information transmission apparatus 2500 provided by an embodiment of the present application. As shown in FIG. 25, the apparatus 2500 includes a receiving module 2501 and a sending module 2502.

[0446] In a possible implementation, the apparatus 2500 is configured to implement the steps corresponding to the first device in the method 900 described above.
