Technical Field

[0002] The present application relates to the field of communications, and more particularly, to a communication method and a communication device. Background Art

[0003] Wireless local area networks (WLANs) have gone through multiple generations, supporting IEEE 802.11 standards such as 802.11ax, 802.11be, and 802.11bn. 802.11ax is known as high efficiency (HE), 802.11be (Wi-Fi 7) is known as extremely high throughput (EHT), and 802.11bn (Wi-Fi 8) is known as ultra-high reliability (UHR).

[0004] Currently, the 802.11be standard supports triggering HE (Trigger-based) physical layer protocol data units (PPDUs), further supporting the triggering of EHT (Electronic Heterogeneous Telecommunications) (EHT) TB (Physical Layer Protocol Data Unit) (PPDUs). As the standard evolves, further research is needed to determine how to indicate or trigger additional PPDU types based on trigger frames. Summary of the Invention

[0005] The embodiments of the present application provide a communication method and a communication device that can support multiple types of PPDU triggering.

[0006] In a first aspect, a communication method is provided. The method may be executed by a station, or by a component of the station (eg, a chip or circuit), without limitation. For ease of description, the method is described using station execution as an example.

[0007] The method may include: the station receives a trigger frame from an access point, the trigger frame including a common information field and at least one special user information field; the station determines the type of the trigger-based TB physical layer protocol data unit PPDU transmitted on the main 160 channel and / or the slave 160 channel based on the first information carried in the common information field and the version and / or uplink bandwidth corresponding to the at least one special user information field.

[0008] In the above technical solution, without adding additional indication information, the site determines the type of TB PPDU transmitted on the main 160 channel and / or the slave 160 channel by combining the information that the special user information field itself needs to carry.

[0009] In certain implementations of the first aspect, determining the type of a TB PPDU transmitted on a primary 160 channel and / or a slave 160 channel includes: first information being a first value, the first value indicating that the TB PPDU transmitted on the primary 160 channel is a PPDU of a version later than the high-efficiency HE version; at least one special user information field including a special user information field corresponding to the first version and a special user information field corresponding to the second version; the uplink bandwidth corresponding to the special user information field of the first version is a first bandwidth; the uplink bandwidth corresponding to the special user information field of the second version is a second bandwidth; the first version and the second version are two different versions later than the HE version; the site determines to transmit the first version of the PPDU on the primary 160 channel and / or to transmit the second version of the PPDU on the slave 160 channel.

[0010] It should be understood that in this solution, there are special user information fields for the first version and the second version, that is, the AP indicates that different versions of the PPDU of the two versions are transmitted on the main 160 channel and the slave 160 channel respectively. The STA needs to further determine which version of the PPDU to transmit based on the meaning of the bandwidth combination corresponding to the first bandwidth and the second bandwidth.

[0011] In certain implementations of the first aspect, the site determines the type of TB PPDU transmitted on the main 160 channel and / or the slave 160 channel based on the first information carried in the common information field and the version and / or uplink bandwidth corresponding to at least one special user information field, including: the site determines the type of TB PPDU transmitted on the main 160 channel and / or the slave 160 channel based on the first information carried in the common information field, the version corresponding to at least one special user information field, and the order of at least one special user information field.

[0012] In the above technical solution, the type of the TB PPDU transmitted on the master 160 channel and / or the slave 160 channel may also be determined in combination with the order of the special user information fields.

[0013] For example, the order can be positive order, reverse order, or an order based on a specific rule. For example, if the specified order is positive order, if the special user information field of the first version is placed before the special user information field of the second version, the STA is instructed to transmit the first version of the PPDU on the primary 160 channel and / or to transmit the second version of the PPDU on the secondary 160 channel. For another example, if the specified order is reverse order, if the special user information field of the first version is placed before the special user information field of the second version, the STA is instructed to transmit the second version of the PPDU on the primary 160 channel and / or to transmit the first version of the PPDU on the secondary 160 channel.

[0014] In certain implementations of the first aspect, the site determines the type of TB PPDU transmitted on the main 160 channel and / or the slave 160 channel based on the first information carried in the common information field and the version and / or uplink bandwidth corresponding to at least one special user information field, including: the first information is a first value, the first value indicates that the TB PPDU transmitted on the main 160 channel is a PPDU after the high-efficiency HE version, the at least one special user information field includes a special user information field of the first version and a special user information field of the second version, the first version and the second version are two different versions after the HE version, the site determines to transmit the first version of the PPDU on the main 160 channel, and / or, to transmit the second version of the PPDU on the slave 160 channel, wherein the special user information field of the first version is before the special user information field of the second version.

[0015] In certain implementations of the first aspect, the station determines the type of the TB PPDU transmitted on the primary 160 channel and / or the slave 160 channel based on the first information carried in the common information field and the version and / or uplink bandwidth corresponding to the at least one special user information field, including: the first information is a first value, the first value indicates that the TB PPDU transmitted on the primary 160 channel is a PPDU after the high-efficiency HE version, the at least one special user information field includes a special user information field of a first version and a special user information field of a second version, the first version and the second version are two different versions after the HE version, the station determines to transmit the first version of the PPDU on the primary 160 channel and / or to transmit the second version of the PPDU on the slave 160 channel, wherein the uplink bandwidth of the special user information field of the first version is a third bandwidth, the uplink bandwidth of the special user information field of the second version is a fourth bandwidth, the third bandwidth is associated with the primary 160 channel, and the fourth bandwidth is associated with the slave 160 channel.

[0016] It is understood that in this solution, some uplink bandwidths can be associated with the primary 160-channel, and other uplink bandwidth values ​​can be associated with the secondary 160-channel. If the uplink bandwidth corresponding to a special user information field is associated with the primary 160-channel, the PPDU corresponding to the version of the special user information field is sent on the primary 160-channel. If the uplink bandwidth corresponding to a special user information field is associated with the secondary 160-channel, the PPDU corresponding to the version of the special user information field is sent on the secondary 160-channel.

[0017] In certain implementations of the first aspect, the actual uplink bandwidth corresponding to the special user information field of the first version and the special user information field of the second version is 160 MHz.

[0018] In certain implementations of the first aspect, if the uplink bandwidth indicated by the special user information field of the first version or the special user information field of the second version is 320 MHz, then 320 MHz represents the uplink bandwidth corresponding to the aggregated PPDU composed of the first version PPDU and the second version PPDU.

[0019] In certain implementations of the first aspect, the site determines the type of TB PPDU transmitted on the primary 160 channel and / or the slave 160 channel based on the first information carried in the common information field and the version and / or uplink bandwidth corresponding to at least one special user information field, including: the first information is the second value, the second value indicates that the TB PPDU transmitted on the primary 160 channel is a high-efficiency HE PPDU, at least one special user information field only includes the special user information field of the first version, the first version is any version after the HE version, the site determines to transmit the HE PPDU on the primary 160 channel, and / or, to transmit the first version of the PPDU on the slave 160 channel.

[0020] In the above technical solution, only the first version special user information field exists, thus indicating that the first version PPDU is transmitted from the 160 channel.

[0022] In the above technical solution, only the first version special user information field exists, thus indicating that the first version PPDU is transmitted on the main 160 channel.

[0023] It can be understood that in this solution, the station does not need to pay attention to the uplink bandwidth indicated in the special user information field. If the uplink bandwidth indicated by the special user information field of the first version is less than 320MHz, the AP will not allocate resources to the STA on channel 160.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts should fall within the scope of protection of this application.

[0089] Before introducing the embodiments of the present application, the following points are first explained.

[0090] First, in this application, unless otherwise specified or there is a logical conflict, the terms and / or descriptions between different embodiments are consistent and can be referenced by each other. The technical features in different embodiments can be combined to form new embodiments based on their internal logical relationships.

[0091] It can be understood that some optional features in the embodiments of the present application may not depend on other features in certain scenarios, and may also be combined with other features in certain scenarios, without limitation.

[0092] It can be understood that the solutions in the embodiments of this application can be used in combination, and the explanations or descriptions of each term, similar operations or steps appearing in the embodiments can be referenced or explained with each other in each embodiment, and this application does not limit this.

[0093] Second, in this application, "at least one" means one or more, and "more" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. In the text description of this application, the character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b and c can mean: a, or b, or c, or a and b, or a and c, or b and c, or a, b and c. Wherein a, b and c can be single or multiple, respectively.

[0094] Third, throughout this application, the terms "first," "second," and various numerical references are used for descriptive purposes only and are not intended to limit the scope of the embodiments of this application. For example, they are used to distinguish between different messages, rather than to describe a specific order or sequence. It should be understood that these references are interchangeable, where appropriate, to allow for the description of scenarios beyond the embodiments of this application.

[0095] Fourth, in this application, the terms "comprise" and "have" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or are inherent to these processes, methods, products or apparatuses.

[0096] Fifth, in this application, "indication" can include direct indications and indirect indications. When describing that a certain indication information indicates A, it can include that the indication information directly indicates A or indirectly indicates A, but it does not mean that the indication information must contain A.

[0097] Sixth, in this application, "sending information to XX (device)" can be understood as the destination of the information being the device. This can include sending information to the device directly or indirectly. "Receiving information from XX (device) or receiving information from XX (device)" can be understood as the source of the information being the device, which can include receiving information from the device directly or indirectly. The information may undergo necessary processing between the source and destination, such as format changes, but the destination can still understand the valid information from the source.

[0098] Sixth, in this application, the term "field" may generally refer to a portion of information. "Field" may also be referred to as "domain" or "field." Furthermore, the names of the fields in this application are merely examples and may be used in other implementations. This application does not impose any specific limitations on these terms.

[0099] Seventh, the arrows or boxes shown by dotted lines in the schematic diagrams in the accompanying drawings of this application specification represent optional steps or optional modules.

[0100] The technical solution provided in the embodiments of the present application can be applied to wireless local area network (WLAN) scenarios. WLAN has gone through multiple generations so far, for example, supporting IEEE 802.11 related standards, such as 802.11a / b / g, 802.11n, 802.11ac, 802.11ax, 802.11be, 802.11bn, etc. Among them, the 802.11n standard is called high throughput (HT), the 802.11ac standard is called very high throughput (VHT), the 802.11ax standard is called high efficiency (HE), the 802.11be (Wi-Fi 7) standard is called extremely high throughput (EHT), and the 802.11bn (Wi-Fi 8) standard is called ultra-high reliability (UHR). Standards before HT, such as 802.11a / b / g, are collectively referred to as Non-HT (non-high throughput). In addition, the technology provided by this application can also be applied to wireless personal area network systems based on ultra-wide band (UWB), such as the IEEE 802.15 series of standards, and can also be applied to sensing systems, such as the IEEE 802.11bf series of standards.

[0101] Although the embodiments of the present application are mainly described by taking the deployment of a WLAN network, especially a network using the IEEE 802.11 system standard as an example, it will be readily understood by those skilled in the art that the various aspects involved in the embodiments of the present application can be extended to other networks that adopt various standards or protocols, such as a high performance wireless local area network (HIPERLAN), a wireless wide area network (WWAN), a wireless personal area network (WPAN), or other networks now known or developed later. Therefore, regardless of the coverage range and wireless access protocol used, the various aspects provided in the embodiments of the present application can be applied to any suitable wireless network. For example, the embodiments of the present application can also be applied to wireless local area network systems such as the Internet of Things (IoT) network or the Vehicle to X (V2X) network. Of course, the embodiments of the present application can also be applied to other possible communication systems, such as long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD), universal mobile telecommunication system (UMTS), world-wide interoperability for microwave access (WiMAX) communication system, fifth generation (5G) communication system, and future sixth generation (6G) communication system, etc.

[0102] The above-mentioned communication system applicable to the present application is only an example, and the communication system applicable to the present application is not limited to this. It is described uniformly here and will not be repeated below.

[0103] A WLAN may include multiple basic service sets (BSSs), where network nodes are stations (STAs) and access points (APs). Each BSS may include an AP and multiple STAs associated with the AP.

[0104] The AP in the embodiment of the present application may also be referred to as a wireless access point or hotspot, etc. AP is an access point for mobile users to enter the wired network. It is mainly deployed in homes, inside buildings, and inside campuses. The typical coverage radius is tens of meters to hundreds of meters. Of course, it can also be deployed outdoors. AP is equivalent to a bridge connecting the wired network and the wireless network. Its main function is to connect various wireless network clients together and then connect the wireless network to the Ethernet. For example, the AP can be a device that supports the 802.11ax protocol and a device that supports the 802.11ax next-generation Wi-Fi protocol. Furthermore, the AP can support the next generation of 802.11be, such as Wi-Fi 8, UHR and other 802.11 series protocols or subsequent versions and other one or more WLAN standards. For example, the AP in the present application can be a HE STA or an EHT STA, or it can be a STA applicable to a future generation of Wi-Fi standards.

[0105] The STA in the embodiments of the present application can be a wireless communication chip, a wireless sensor, or a wireless communication terminal. For example, a mobile phone that supports Wi-Fi communication, a tablet computer that supports Wi-Fi communication, a set-top box that supports Wi-Fi communication, a smart TV that supports Wi-Fi communication, a smart wearable device that supports Wi-Fi communication, an in-vehicle communication device that supports Wi-Fi communication, and a computer that supports Wi-Fi communication. For example, the STA can be a device that supports the 802.11ax standard and a device that supports the next-generation 802.11ax Wi-Fi protocol. Furthermore, the AP can support one or more WLAN standards, such as the next generation of 802.11be, 802.11 series protocols such as Wi-Fi 8, UHR, or subsequent versions.

[0106] In an embodiment of the present application, as an example structure, a STA or AP includes a hardware layer, an operating system layer running on the hardware layer, and an application layer running on the operating system layer. The hardware layer includes hardware such as a central processing unit (CPU), a memory management unit (MMU), and memory (also called main memory). The operating system can be any one or more computer operating systems that implement business processing through processes, such as a Linux operating system, a Unix operating system, an Android operating system, an iOS operating system, or a Windows operating system. The application layer includes applications such as browsers, address books, word processing software, and instant messaging software. The above examples do not limit the specific structure of the execution subject of the method provided in the embodiment of the present application to a unique implementation form. As long as it is possible to communicate according to the method provided in the embodiment of the present application by running a program that records the code of the method provided in the embodiment of the present application, for example, the execution subject of the method provided in the embodiment of the present application can be a STA or AP, or a functional module in the STA or AP that can call and execute a program.

[0107] In addition, various aspects or features of the present application can be implemented as methods, apparatuses, or articles of manufacture using standard programming and / or engineering techniques. The term "article of manufacture" as used in this application covers computer programs that can be accessed from any computer-readable device, carrier, or medium. For example, computer-readable media may include, but are not limited to: magnetic storage devices (e.g., hard disks, floppy disks, or magnetic tapes, etc.), optical disks (e.g., compact discs (CDs), digital versatile discs (DVDs), etc.), smart cards, and flash memory devices (e.g., erasable programmable read-only memories (EPROMs), cards, sticks, or key drives, etc.). In addition, the various storage media described herein may represent one or more devices and / or other machine-readable media for storing information. The term "machine-readable medium" may include, but is not limited to, wireless channels and various other media capable of storing, containing, and / or carrying instructions and / or data.

[0108] Figure 1 is a schematic diagram of a network architecture of a wireless local area network applicable to an embodiment of the present application. As shown in Figure 1, an AP can be associated with one or more STAs, that is, an AP can communicate with one or more STAs. As shown in Figure 1, the network architecture of a wireless local area network can also include multiple APs, and different APs can also communicate with each other. For example, as shown in Figure 1, AP#1 and AP#2 are shown, as well as STA 11 and STA 12 associated with AP#1. Data can be transmitted between AP#1 and STA 11 or STA 12, data can be transmitted between STA 11 and STA 12, and AP#1 and AP#2 can also communicate with each other.

[0109] It should be understood that Figure 1 is only exemplary and should not limit the network architecture of the wireless local area network to which the present application is applicable. For example, the network architecture can also include more APs, and each AP can also be associated with more STAs. The embodiments of the present application are not limited here.

[0110] Figure 2 is a schematic diagram of the frame structure of the trigger frame in the 802.11ax standard (HE). The trigger frame includes a common information field (Common Info) and a user information list field (User Info List), wherein the common information field contains common information applicable to all STAs indicated in the trigger frame, and the user information list field contains multiple user information fields (User Info). Each user information field corresponds to information applicable to one STA. In the user information field, the association identification 12 (AID12) represents the association identifier of a certain STA, and the resource unit (RU) allocation field (RU Allocation) is used to indicate the location of the RU allocated to this STA (the STA indicated by AID12). The trigger frame is used to trigger the STA corresponding to the user information field to send a trigger-based (TB) physical layer protocol data unit PPDU (physical layer protocol data unit) on the allocated RU.

[0111] To enable the trigger frame to trigger the EHT TB PPDU, the 802.11 standard updated the trigger frame. However, this update did not redefine a dedicated trigger frame for triggering the EHT TB PPDU. Instead, it was shared with the HE trigger frame, meaning that the trigger frame evolved to be able to trigger either the HE TB PPDU or the EHT TB PPDU.

[0112] It should be noted that for the trigger frame common information field in the 802.11be standard, non-EHT HE non-AP STAs will interpret the common information field as the HE variant common information field (i.e., interpret the common information field according to Figure 2). If B54 and B55 in the common information field are equal to 1, the EHT non-AP STA interprets the common information field as the HE variant common information field; otherwise, the common information field is interpreted as the EHT variant common information field (i.e., interpret the common information field according to Figure 3 below).

[0113] Figure 3 illustrates the structure of a trigger frame for an EHT variant. This trigger frame includes a Common Info field and a User Info List field. The fields in the Common Info field are detailed in Figure 3. For the specific meaning of each field in the Common Info field, refer to the protocol description. The User Info List field contains multiple User Info fields, each of which includes an AID12 field. The AID12 field of the first User Info field has a value of 2007, which carries some common information. Although the first User Info field is a User Info field, it carries common information and can therefore be called a special User Info field. It should be noted that after a STA associates with an AP, it obtains an AID. When triggering an EHT STA, the AP will not assign an AID of 2007 to any STA. Therefore, there will be no ambiguity when a STA receives a trigger frame containing an AID12 value of 2007. Starting from the second user information field, the AID12 field of the user information field specifically points to a STA user. The user information field contains the information that the pointed STA user needs to read. The resource unit allocation field (RU allocation) and the primary and secondary 160 fields in the user information field jointly indicate the location of the specific resource unit (RU) or multiple resource unit (MRU) allocated to this STA user. Among them, if the width of the RU or MRU allocated to the STA is less than or equal to 2*996tone, if the PS160 field is set to 0, it means that the RU or MRU is allocated to P160, and if the PS160 field is set to 1, it means that the RU or MRU is allocated to S160. Otherwise, the PS160 field and the resource unit allocation field together represent the RU or MRU index. In order to facilitate understanding of the solution of the embodiment of the present application, here is a brief introduction to the uplink bandwidth extension (UL BW Extension) field and the physical layer version identifier (PHY Version Identifier) ​​field contained in the special user information field.

[0114] Among them, the uplink bandwidth extension field in the special user information field and the uplink bandwidth (UL BW) field in the common information field together indicate the uplink bandwidth of the triggered TB PPDU, wherein the uplink bandwidth extension field and the uplink bandwidth field each occupy 2 bits. Specifically, as shown in Table 1, the uplink bandwidth field value is 0 and the uplink bandwidth extension field value is 0, indicating 20 MHz, the uplink bandwidth field value is 1 and the uplink bandwidth extension field value is 0, indicating 40 MHz, the uplink bandwidth field value is 2 and the uplink bandwidth extension field value is 0, indicating 80 MHz, the uplink bandwidth field value is 3 and the uplink bandwidth extension field value is 1, indicating 160 MHz, the uplink bandwidth field value is 3 and the uplink bandwidth extension field value is 2, indicating 320 MHz-1, and the uplink bandwidth field value is 3 and the uplink bandwidth extension field value is 3, indicating 320 MHz-2.

[0115] The physical layer version identifier in the special user information field indicates which version the special user information field belongs to. The 802.11be trigger frame contains only one special user information field, and the physical layer version identifier in the special user information field indicates that the special user information field belongs to the EHT version.

[0116] It is understood that the Special User Information field can be considered a supplement to the Common Information field. For example, to trigger a STA to send an EHT PPDU, the STA also needs to read the relevant fields in the EHT version of the Special User Information field to obtain the complete parameters for sending the EHT PPDU, thereby enabling the transmission of the EHT PPDU.

[0117] In addition, FIG3 respectively marks the number of bits occupied by the fields contained in the common information field and the user information list field. This is only used as an example. For example, B0 to B11 corresponding to the AID12 field in the user information 1 indicate that the AID12 field is the first 12 bits in the user information 1 field.

[0118] Table 1

[0119] Figure 4 is a schematic diagram of a possible 320MHz channel distribution in the 802.11be standard. As shown in Figure 4, the entire 320MHz channel can be divided into a primary 20MHz channel, a secondary 20MHz channel, a secondary 40MHz channel, a secondary 80MHz channel, and a secondary 160MHz channel (S160). For ease of description, the primary 20MHz channel may be referred to as P20 and the secondary 20MHz channel as S20 in this application. Other descriptions are similar and will not be repeated here. Among them, P20 and S20 form P40, P40 and S40 form P80, and P80 and S80 form P160. In addition, Figure 4 takes P20 at the lowest frequency (i.e., channel 1) as an example. P20 can also be at other frequency positions, and the corresponding positions of S20, S40, S80, and S160 are determined accordingly.

[0120] However, it should be noted that FIG4 is illustrated using the 320 MHz channel as an example. For example, if the channel is a 160 MHz channel, S160 does not exist; if the channel is an 80 MHz channel, S80 does not exist, and the same applies to other channels. The following descriptions are based on the 320 MHz channel as an example unless otherwise specified.

[0121] Because HE only supports a maximum of 160MHz and not 320MHz, HE-type PPDUs can only be transmitted on P160. If a PPDU is transmitted on S160, it must be an EHT-type PPDU. However, an EHT user (i.e., an EHT STA) that is triggered to send a TB PPDU can transmit either an HE-type PPDU or an EHT-type PPDU on P160. Therefore, how does the EHT user know whether to transmit an HE PPDU or an EHT PPDU on the P160 channel? (Alternatively, this problem can be described as how the EHT user knows whether its corresponding user information field is the HE variant's user information field or the EHT variant's user information field.) Currently, the HE / EHT P160 field, based on the common information field of the EHT variant, can solve this problem.

[0122] As shown in Figure 3, in the HE / EHT P160 field of the common information field of the EHT variant (i.e., B54 of the common information field), if the EHT AP sets the HE / EHT P160 field of the common information field to 0, it indicates to the EHT user that the TB PPDU requested in P160 is an EHT TB PPDU. If the HE / EHT P160 field of the common information field is set to 1, it indicates to the EHT user that the TB PPDU requested in P160 is an HE TB PPDU.

[0123] As can be seen, the 802.11be standard enables trigger frames to support triggering of EHT TB PPDUs, in addition to HE TB PPDUs. Further versions exist after EHT. For example, for UHR users, HE / EHT / UHR PPDUs may be transmitted on P160, and EHT / UHR PPDUs may be transmitted on S160. However, how to support triggering of more PPDU types for UHR users or users of versions later than UHR is currently unclear.

[0124] In view of this, the present application proposes a communication method that can effectively solve the above technical problems. The communication method proposed in the present application is described in detail below.

[0125] Fig. 5 is a schematic diagram of a communication method 500 proposed in an embodiment of the present application. The method 500 includes the following steps.

[0126] S510: The AP generates a trigger frame, which includes a common information field and at least one special user information field. The first information carried in the common information field and the version and / or uplink bandwidth corresponding to the at least one special user information field are used to indicate the type of the TB PPDU transmitted on P160 and / or S160.

[0127] It can be understood that the PPDU involved in this application is the TB PPDU, and the related parts will not be described in detail later.

[0128] Optionally, the first information is carried in the first field of the common information field. For example, the first information is a first value, indicating that the TB PPDU transmitted on P160 is a PPDU of a later HE version, and the first information is a second value, indicating that the TB PPDU transmitted on P160 is a HE PPDU.

[0129] It should be understood that this application does not impose any specific restrictions on the name and length of the first field. For example, the length of the first field can be 1 bit, such as bit B54 of the public information field. The name of the first field is the HE / EHT P160 field. The first value of the first information can be 0 and the second value can be 1; alternatively, the first value can be 1 and the second value can be 0.

[0130] Optionally, the first information may also be carried in multiple fields of the common information field, that is, the first information is jointly indicated by multiple fields.

[0131] It should also be understood that the special user information field described in the embodiment of the present application includes an AID field and a physical layer version identification field, wherein the value of the AID field is 2007, and the physical layer identification field indicates the version corresponding to the special user information field.

[0132] Currently, a STA can determine whether a special user information field exists by reading the user information list field or the 1-bit special user information field identifier field in the common information field. Optionally, to increase robustness, relevant indication information can be added to the common information field, such as a bitmap indicating which version of the special user information field exists, or by using an index, a corresponding relationship, or the like to indicate which version of the special user information field exists.

[0133] It should also be understood that there is no special user information field corresponding to the HE version in the 802.11 standard. Therefore, the at least one special user information field included in the trigger frame is a special user information field corresponding to one or more versions of EHT, UHR, and future versions after UHR.

[0134] It should also be understood that the uplink bandwidth corresponding to the special user information field can be jointly indicated by the uplink bandwidth field in the common information field and the uplink bandwidth extension field in the special user information field (see Table 1 and the corresponding description of Table 1), or can also be indicated separately by the uplink bandwidth extension field in the special user information field. This application is not limited to this.

[0135] The following describes in detail how the AP indicates to the STA the type of TB PPDU that can be transmitted on P160 and / or S160 based on the first information and the version and / or uplink bandwidth corresponding to the at least one special user information field.

[0136] For ease of understanding, the following description is based on the meaning when the first information given above takes the first value and the second value as an example.

[0137] (a) If the AP sets the first information to the first value, the trigger frame includes only the special user information field of the first version, and the uplink bandwidth corresponding to the special user information field of the first version is less than 320 MHz, then the STA is instructed to transmit the first version of the PPDU on P160.

[0138] The instruction to transmit the PPDU of the first version on P160 may also be replaced by the description of "indicating to the STA that the TB PPDU requested in P160 is the TB PPDU of the first version".

[0139] It should be noted that if the uplink bandwidth corresponding to the special user information field of the first version is less than 320 MHz, the STA may consider that the PPDU can only be transmitted on P160 and will not be transmitted on S160.

[0140] It should also be noted that in this application, if the AP does not set a special user information field of a certain version in the trigger frame, the STA may assume that the PPDU of this version cannot be transmitted in P160 and S160. This certain version refers to the version after HE.

[0141] (b) If the AP sets the first information to the first value, the trigger frame includes only the special user information field of the first version, and the uplink bandwidth corresponding to the special user information field of the first version is equal to 320 MHz, then the STA is instructed to transmit the first version of the PPDU on P160 and / or S160.

[0142] The above-mentioned scheme (a) and scheme (b) can also be understood as the AP setting the first information to the first value, and the trigger frame only includes the special user information field of the first version, which instructs the STA to transmit the first version of the PPDU on P160 and / or S160. In other words, when determining the specific information of the indication, the STA does not need to pay attention to the uplink bandwidth indicated by the special user information field of the first version, and considers that the first version of the PPDU is transmitted on P160 and / or S160.

[0143] However, it should be noted that if the uplink bandwidth indicated by the special user information field of the first version is less than 320 MHz, the AP will not allocate resources to the STA at S160.

[0144] (c) If the AP sets the first information to the first value, the trigger frame includes the special user information field of the first version and the special user information field of the second version, the uplink bandwidth corresponding to the special user information field of the first version is the first bandwidth, and the uplink bandwidth corresponding to the special user information field of the second version is the second bandwidth, then the STA is instructed to transmit the first version of the PPDU on P160 and / or to transmit the second version of the PPDU on S160.

[0145] It should be understood that in this solution, there are special user information fields for the first version and the second version, that is, the AP instructs to transmit different versions of the PPDU on P160 and S160 respectively.

[0146] It should also be understood that, in principle, the first bandwidth and the second bandwidth can be any combination of values, where the first bandwidth and the second bandwidth are used to indicate the corresponding version information of P160 and S160. For example, the bandwidth combination consisting of {20 MHz, 40 MHz} is assigned a meaning, which indicates that PPDU version #1 is transmitted on P160 and PPDU version #2 is transmitted on S160, where version #1 corresponds to the special user information field indicating an uplink bandwidth of 20 MHz, and version #2 corresponds to the special user information field indicating an uplink bandwidth of 40 MHz. Based on the above definition, if the AP wants to indicate that PPDU version 1 is transmitted on P160 and PPDU version 2 is transmitted on S160, the first bandwidth can be set to 20 MHz and the second bandwidth can be set to 40 MHz.

[0147] It should be noted that in this solution, both the AP and the STA need to clearly understand the meaning of the bandwidth combination corresponding to the first bandwidth and the second bandwidth. For example, the meaning of the first bandwidth and the second bandwidth corresponding to each other can be predefined or specified by the protocol.

[0148] It should also be noted that in this solution, the actual uplink bandwidth of the first and second versions of the TB PPDU triggered by the AP is 160 MHz. The first and second bandwidths (for example, the first and second bandwidths are 20 MHz and 40 MHz, respectively) may not indicate the actual bandwidths that trigger the TB PPDU. This will not be discussed in detail later when similar issues are discussed. Therefore, the logical first and second bandwidths are both 160 MHz. However, if the AP sets both the first and second bandwidths to 160 MHz, there will be a problem: if 160 MHz means that the version of the PPDU corresponding to the special user information field with an uplink bandwidth of 160 MHz is transmitted on P160 (or S160), then when the STA sees that both the first and second bandwidths are 160 MHz, it still cannot determine whether to transmit the first or second version of the PPDU on P160, and thus cannot determine whether to transmit the first or second version of the PPDU on S160.

[0149] Therefore, in this solution, the more logical first bandwidth and second bandwidth are 160 MHz and 320 MHz, where 320 MHz can be interpreted as the uplink bandwidth of the aggregated PPDU (A-PPDU) composed of the first version PPDU and the second version PPDU.

[0150] For example, if the trigger frame includes the special user information field of the first version and the special user information field of the second version, you can also ignore the first bandwidth and the second bandwidth, and directly instruct the STA to transmit the first version of the PPDU on P160 and / or transmit the second version of the PPDU on S160 by default.

[0151] It should be noted that in the prior art, the EHT STA can distinguish whether the common information field is read according to HE or EHT by the presence of a special user information field (determined by B55) and the value of HE / EHT P160 (B54): when the special user field does not exist and HE / EHT P160 corresponds to HE, it is read according to HE, otherwise it is read according to EHT, but this method is not compatible with A-PPDU scenarios. For example, HE / EHT P160 corresponds to HE, but there is a special user information field. In this case, it is an A-PPDU scenario, then S160 should read the common information field according to EHT.

[0152] If the A-PPDU scenario (in which at most there is only one special user information field) is not considered, similarly, the distinction can be made based on whether a certain version of the special user field exists (for example, by reading the special user information field or adding relevant indication information to the common information field) and B54 in the common information field. If HE / EHT P160 corresponds to HE and the special user information field does not exist, the common information field is read according to HE; otherwise, the common information field is read according to the variant of the corresponding version of the special user information field. In addition, without combining B54, the STA can determine how to read the common information field and its own user information field based solely on whether there is a special user field. Because when there is no A-PPDU, at most there is only one special user field in the trigger frame. In this case, when there is no special user information, it is read according to HE; when there is one special user information field, it is read according to the variant of the corresponding version of the existing special user information field.

[0153] It should be noted that regardless of whether the A-PPDU scenario is considered or not, the method of identifying the variant of the special user information field can be used to distinguish how to read the public information field. However, the above method does not require reading the special user information field, and can more quickly identify how to read the public information field.

[0154] A new solution that may replace solution (c) is solution (c1): the AP is based on the first information being a first value, and the trigger frame includes a first version of the special user information field and a second version of the special user information field, and the order of the first version of the special user information field and the second version of the special user information field jointly indicates the type of TB PPDU transmitted on P160 and / or S160.

[0155] For example, the order can be positive, reverse, or a specific rule. For example, if the specified order is positive, and the first version of the special user information field is placed before the second version of the special user information field, the STA is instructed to transmit the first version of the PPDU on P160 and / or the second version of the PPDU on S160. For another example, if the specified order is reverse, and the first version of the special user information field is placed before the second version of the special user information field, the STA is instructed to transmit the second version of the PPDU on P160 and / or the first version of the PPDU on S160.

[0156] It should be understood that in principle, the first bandwidth and the second bandwidth in this solution can be set to any values. The meanings of the first bandwidth and the second bandwidth are consistent with those in solution (c) and will not be repeated here.

[0157] In solution (c), if both the first bandwidth and the second bandwidth are set to the actual uplink bandwidth of 160 MHz, some problems will arise. However, based on solution (c1), even if the first bandwidth and the second bandwidth are both set to 160 MHz, the AP can still overcome the problems in solution (c) by setting the positions of the two special user information fields.

[0158] Optionally, solution (c1) may also be combined with the uplink bandwidth value corresponding to the special user information field to jointly indicate the type of TB PPDU transmitted on P160 and / or S160.

[0159] A new solution that may replace solution (c) is solution (c2): the AP sets the first information to the first value, and the trigger frame includes the special user information field of the first version and the special user information field of the second version, the uplink bandwidth of the special user information field of the first version is the third bandwidth, and the uplink bandwidth of the special user information field of the second version is the fourth bandwidth, wherein the third bandwidth is associated with P160 and the fourth bandwidth is associated with S160.

[0160] It is understood that in this solution, the AP can associate some uplink bandwidths with P160 and other uplink bandwidth values ​​with S160. If the uplink bandwidth corresponding to a special user information field is associated with P160, the PPDU version corresponding to the special user information field is sent on P160. If the uplink bandwidth corresponding to a special user information field is associated with S160, the PPDU version corresponding to the special user information field is sent on S160.

[0161] Optionally, the existing uplink bandwidth value in the last column of Table 1 can be associated with P160, and one or more reserved items in Table 1 can be assigned any bandwidth value and associated with S160. For example, the reserved item corresponding to the UL BW field value of 0 and the UL BW Extension field value of 1 in Table 1 is modified to 160, and this 160 is associated with S160.

[0162] Similarly, in solution (c), if the uplink bandwidth of the special user information field of both the first and second versions is set to the actual uplink bandwidth of 160 MHz, some problems will arise. However, based on solution (c2), even if the special user information field of both the first and second versions is set to 160 MHz, the AP can overcome the problems in solution (c) by setting two 160 MHz bands, one associated with P160 and the other associated with S160.

[0163] It should be understood that the above description uses P160 and S160 as examples. The core point of this solution is to associate bandwidth with the primary and secondary frequency domain positions or absolute frequency domain positions (i.e., the frequency domain range corresponding to the bandwidth). It can also be understood that this solution aims to help STAs determine the type of the corresponding user information field by using entries (which may be newly added entries). An entry not only indicates the bandwidth but also the primary and secondary frequency domain positions or absolute frequency domain positions of the bandwidth. For example, if different types of TB PPDUs are supported for transmission on P80, S80, and S160, then different entries can be allocated to P80, S80, and S160 in this solution. Similarly, if different types of TB PPDUs are supported for transmission on the low frequency 80 of P40, S40, S80, and S160 and the high frequency 80 of S160, then different entries can also be allocated to the low frequency 80 of P40, S40, S80, and S160 and the high frequency 80 of S160. Examples are not given here one by one.

[0164] (d) If the AP sets the first information to the second value, the second value indicates that the TB PPDU transmitted on P160 is an HE PPDU, and at least one special user information field only includes the special user information field of the first version, then the STA is instructed to transmit the HE PPDU on P160 and / or transmit the first version PPDU on S160.

[0165] Specifically, in this solution, the second value is used to indicate that the PPDU of the first version is transmitted on P160, and the special user information field of the first version that only exists is used to indicate that the PPDU of the first version is transmitted on S160.

[0166] It should be understood that, in principle, the uplink bandwidth corresponding to the special user information field of the first version (hereinafter referred to as uplink bandwidth #1) can be set to any value.

[0167] However, it should be noted that in this solution, the actual uplink bandwidth of the first version of the TB PPDU triggered by the AP is 160 MHz. The first bandwidth indicated by the special user information field (for example, bandwidth #1 is 20 MHz) may not be the actual uplink bandwidth that triggers the first version of the TB PPDU. Therefore, for example, the logical bandwidth #1 is 160 MHz. For example, the logical bandwidth #1 can also be 320 MHz. Similarly, the physical meaning of 320 MHz can be interpreted as the uplink bandwidth of the A-PPDU composed of the HE version and the first version of the PPDU.

[0168] For example, in this solution, the AP may set the uplink bandwidth of only one configured special user information field to S160 in solution (c2) to indicate that the PPDU of the version corresponding to the special user information field is transmitted at S160.

[0169] (e) If the AP sets the first information to the second value, the second value indicates that the TB PPDU transmitted on P160 is a HE PPDU, and the trigger frame does not include the special user information field, then the STA is instructed to transmit only HE PPDU on P160.

[0170] It can be understood that the existence of special user information of version #1 in the above description can be understood as the existence of at least one special user information field of version #1 indicating a physical layer version identifier.

[0171] Based on the descriptions in (a) to (e) above, taking the trigger frame including the special user information field of EHT and the special user information field of UHR, the first value corresponding to the first information is 0 (indicating that the TB PPDU transmitted on P160 is a PPDU of one of the EHT version and the UHR version), and the second value is 1 (indicating that the TB PPDU transmitted on P160 is a HE version PPDU) as an example, several specific tables that may be referenced when the AP indicates to the STA the type of TB PPDU transmitted on P160 and / or S160 are given, see Table 2, Table 3, and Table 4 below.

[0172] It should be noted that the first five rows corresponding to when the first information is 0, and the three rows corresponding to when the first information is 1 in Tables 2 to 4 are the same (corresponding to solutions (a) and (b)). Specifically, of the first five rows corresponding to when the first information is 0, the first four rows correspond to solution (a), and the fifth row corresponds to solution (b); of the three rows corresponding to when the first information is 1, the first two rows correspond to solution (d), and the third row corresponds to solution (e).

[0173] The difference between Table 2, Table 3 and Table 4 is that the last two rows corresponding to the first information of Table 2 when it is 0 correspond to solution (c), the last three rows corresponding to the first information of Table 2 when it is 0 correspond to solution (c1), and the last two rows corresponding to the first information of Table 2 when it is 0 correspond to solution (c2).

[0174] Table 2

[0175] Table 3

[0176] Note that in Table 3, the uplink bandwidth for both EHT and UHR is set to 160 MHz. Because legacy EHT STAs may not be able to read data in sequential order, if the order is set to positive and the UHR special user information field precedes the EHT special user information field, then when an EHT STA reads a special user field with AID 2007 and a bandwidth of 160 MHz, it may interpret the TB PPDU indicated by the AP for transmission on P160 as an EHT PPDU, thereby conflicting with the transmission method indicated in the second-to-last row when the first information is 0. In this case, the second-to-last row can be replaced with the method corresponding to the last row when the first information is 0. This allows legacy EHT STAs to interpret the EHT uplink bandwidth as 320 MHz. This prevents conflicts as long as the AP does not allocate resources to legacy EHT STAs on P160. However, in this case, the STA may use either 320 MHz (i.e., the uplink bandwidth of the A-PPDU) or 160 MHz (the actual bandwidth of the EHT PPDU to which the STA responds) when returning the TB PPDU.

[0177] Table 4

[0178] It should be noted that S160 in Table 4 indicates that the uplink bandwidth indicated by the corresponding special user information field is associated with channel 160.

[0179] Note that in Table 4, the uplink bandwidth for both EHT and UHR is set to 160 MHz. Since legacy EHT STAs may not be able to read S160, when an EHT STA reads a special user field with AID 2007 and a bandwidth of 160 MHz, it may interpret the TB PPDU indicated by the AP for transmission on P160 as an EHT PPDU, thereby conflicting with the transmission method indicated in the second-to-last row when the first information is 0. In this case, the second-to-last row can be replaced with the method corresponding to the last row when the first information is 0. This allows legacy EHT STAs to interpret the EHT uplink bandwidth as 320 MHz. In this case, as long as the AP does not allocate resources to legacy EHT STAs on P160, there will be no conflict. However, in this case, the STA may need to use an uplink bandwidth of 320 MHz when transmitting the TB PPDU.

[0180] S520: The AP sends a trigger frame to the STA. Correspondingly, the STA receives the trigger frame from the AP.

[0181] After receiving the trigger frame, if the STA parses the trigger frame and finds a user information field that matches its own AID, the STA will then send a TB PPDU on the specific resources (RU or MRU) allocated to it.

[0182] For example, a STA can determine the location of its allocated resources based on the resource unit allocation (RU allocation) field in its user information field and information A carried in its user information field (for the specific meaning of information A, see the meaning of the primary and secondary 160 (PS160) field in Figure 3). The specific resources allocated by the AP to the STA are located in P160 and / or S160.

[0183] For example, information A is carried in the second field of the user information field.

[0184] The present application does not impose any specific restrictions on the name and length of the second field. For example, the name of the second field is the PS160 field, and the second field is a field with a length of 1 bit.

[0185] S530: The STA determines the type of the TB PPDU transmitted on P160 and / or S160 based on the first information carried in the common information field in the trigger frame and the version and / or uplink bandwidth corresponding to the at least one special user information field.

[0186] Regarding how the STA determines the type of the TB PPDU transmitted on P160 and / or S160, please refer to the description of how the AP indicates the type of the TB PPDU transmitted on P160 and / or S160 in S510, which will not be repeated here.

[0187] In one implementation, since the specific resources (RU or MRU) allocated to the STA are located in P160 and / or S160, in practice the STA needs to jointly determine the type of TB PPDU it transmits on P160 and / or S160 based on the first information carried in the common information field, the version and / or uplink bandwidth corresponding to at least one special user information field, and the information A in the user information field corresponding to the STA.

[0188] Taking Table 2 as an example, if the first information indicates 0, the trigger frame only includes the special user information field of UHR, and the information A carried in the user information field of STA indicates P160. Based on the above conditions, STA only needs to jointly determine to transmit UHR PPDU on P160 (or on the resources corresponding to STA), and does not need to pay attention to S160; for another example, if the first information indicates 0, the trigger frame includes special user information fields of EHT and UHR, and the uplink bandwidths of EHT and UHR are 160 MHz and 320 MHz (320-1 or 320-2) respectively, and the information A carried in the user information field of STA indicates S160. Based on the above conditions, STA only needs to jointly determine to transmit UHR PPDU on S160 (or on the resources corresponding to STA), and does not need to pay attention to P160.

[0189] In another implementation, the STA may determine a User Information field variant corresponding to the STA based on the first information carried in the common information field, the version and / or uplink bandwidth corresponding to at least one special user information field, and information A in the User Information field corresponding to the STA. The STA may further parse the User Information field corresponding to the STA based on the frame structure of the determined User Information field variant. In this application, the STA's determination of the type of the TB PPDU transmitted on P160 and / or S160 and the STA's determination of the User Information field variant corresponding to the STA may be interchangeable implementations and are not limited thereto.

[0190] Optionally, the method further includes:

[0191] S540: The STA sends a TB PPDU to the AP. Correspondingly, the AP receives the TB PPDU from the STA.

[0192] The version corresponding to the TB PPDU is the version determined by the STA in S530 based on the information A carried in its own user information field.

[0193] Optionally, if the TB PPDU sent by the STA is included in the A-PPDU, the bandwidth carried in the TB PPDU can be the bandwidth of the A-PPDU or the bandwidth corresponding to its own version of the PPDU. This application does not impose any restrictions.

[0194] The bandwidth carried in the TB PPDU sent by the STA is illustrated based on Table 2. If the first information indicates 0, the trigger frame includes special user information fields for EHT and UHR, the uplink bandwidths of EHT and UHR are 160 MHz and 320 MHz (320-1 or 320-2), respectively, and the information A carried in the user information field of the STA indicates S160, the STA jointly determines to transmit the UHR TB PPDU (i.e., the TB PPDU sent by the STA) at S160 based on the above conditions. For example, the bandwidth carried in the UHR TB PPDU can be 320 MHz or 160 MHz.

[0195] The method 500 is described in detail above. It can be seen that this method indicates to the STA the type of TB PPDU transmitted on P160 and / or S160 by combining the number of special user information fields, the version information corresponding to the special user information fields, and the uplink bandwidth without adding additional indication information.

[0196] Two methods for indicating the type of TB PPDU transmitted on P160 and / or S160 are described below in conjunction with FIG6 and FIG7 . The methods shown in FIG6 and FIG7 differ from method 500 in that the following two methods require additional indication information (e.g., additional bits) for indication. Detailed descriptions are provided below.

[0197] Fig. 6 is a schematic diagram of a communication method 600 proposed in an embodiment of the present application. The method 600 includes the following steps.

[0198] At step S610, the AP generates a trigger frame, the trigger frame including a common information field and second information, the common information field including first information, wherein the first information and the second information jointly indicate that one of the EHT PPDU and the UHR PPDU is transmitted at P160, and that one of the EHT PPDU and the UHR PPDU is transmitted at S160.

[0199] Optionally, the first information is carried in the first field of the common information field. For example, the first information is a first value, indicating that the TB PPDU transmitted on P160 is a PPDU of a later HE version, and the first information is a second value, indicating that the TB PPDU transmitted on P160 is a HE PPDU.

[0200] It should be understood that the present application does not impose any specific restrictions on the name and length of the first field. For example, the name of the first field is the HE / EHT P160 field, and the first field is a field with a length of 1 bit.

[0201] Optionally, the first information may also be carried in multiple fields in the common information field, that is, the first information is jointly indicated by multiple fields.

[0202] Optionally, the second information may be carried in one or more fields of the public information field, or the second information may also be carried in one or more fields of the user information field.

[0203] For ease of understanding, the following provides examples of several tables that may be referenced when the AP indicates the type of TB PPDU transmitted on P160 and / or S160, assuming that the first information is 1-bit information, the first value of the first information is 0, and the second value is 1. For details, see Table 5, Table 6, Table 7, and Table 8.

[0204] Example 1: The second information is 2-bit information. For the specific meaning of the joint indication of the first information and the second information, see Table 5.

[0205] Table 5

[0206] Specifically, based on Table 5, the AP can indicate the transmission of the HE PPDU on P160 by setting the first information to 1, and indicate the transmission of one of the EHT PPDU and UHR PPDU on S160 by the value corresponding to the second information (i.e., the newly added 2 bits). Alternatively, the AP can indicate the transmission of a PPDU on P160 that indicates a PPDU of a later HE version (i.e., one of the EHT PPDU and UHR PPDU) by setting the first information to 0. Since only the EHT PPDU and UHR PPDU can be transmitted on S160, there are a total of four possible combinations of the situations on P160 and S160. The AP can further specifically indicate the type of PPDU transmitted on P160 and S160 through the four values ​​corresponding to the second information.

[0207] It should be noted that the corresponding meanings of different values ​​of the second information in Table 5 are only examples. For example, when the first information is 1, the second information is 10, indicating that S160 corresponds to UHR, and the second information is 11, indicating that S160 corresponds to EHT. The corresponding meanings of 00 and 01 are reserved. The tables described later in this application are only exemplary descriptions, and the relevant parts will not be repeated one by one.

[0208] Example 2: The second information is 1 bit long. For the specific meaning of the joint indication of the first information and the second information, see Table 5.

[0209] Table 6

[0210] The difference between Table 6 and Table 5 is that the second information is 1-bit information. Therefore, when the first information is 0, since the second information is 1-bit information, the four situations after the combination of the situations on P160 and S160 cannot be defined by 1 bit. Therefore, when the first information is 0 in Table 6, the corresponding descriptions when the second information is 0 and 1 can be the descriptions corresponding to any two values ​​of 0, 00, 01, 10 and 11 of the first information in Table 5. For example, the corresponding descriptions when the first information is 0 and the second information is 0 and 1 in Table 6 are the descriptions corresponding to the first information being 0, 00 and 10 in Table 5, respectively, which will not be repeated here.

[0211] Optionally, the first information and the second information jointly indicate that the first information, the second information, and the special user information field jointly indicate that one of the EHT PPDU and the UHR PPDU is transmitted on P160, and that a PPDU after the HE version (i.e., one of the EHT PPDU and the UHR PPDU) is transmitted on S160.

[0212] Example 3: The second information is 1-bit in length. For the specific meaning of the joint indication of the first information, the second information and the special user information field (whether it exists), see Table 7.

[0213] Table 7

[0214] Specifically, based on Table 7, the AP can indicate transmission of an HE PPDU on P160 by setting the first information to 1, and can indicate transmission of a PPDU of the version corresponding to the existing special user information field on S160 by configuring only one special user information field in the user information list field. Alternatively, the AP can indicate transmission of a PPDU of the version corresponding to the existing special user information field on both P160 and S160 by setting the first information to 0. Alternatively, the AP can indicate transmission of an HE PPDU on P160 by setting the first information to 1, and indicate transmission of different versions of the PPDU on P160 and S160 by configuring the EHT special user information field and the UHR special user information field in the user information list field. The AP indicates which PPDU version to transmit by setting the value of the second information. For example, a value of 0 in the second information indicates that P160 corresponds to EHT and S160 corresponds to UHR, while a value of 1 in the second information indicates that P160 corresponds to UHR and S160 corresponds to EHT.

[0215] Example 4: The second information is 2-bit information. For the specific meanings of the first information, the second information, and other configuration joint indications, see Table 8.

[0216] Table 8

[0217] Table 8 differs from Table 6 in that when the second information is 0, other configurations may be used to indicate a future configuration, such as considering more versions of PPDUs after UHR. This value may be combined with other bits or certain fields, such as whether a special user information field exists, to indicate this.

[0218] S620: The AP sends a trigger frame to the STA. Correspondingly, the STA receives the trigger frame from the AP.

[0219] For S620, please refer to the description in S520 and will not be repeated here.

[0220] S630: The STA determines the type of the TB PPDU transmitted on P160 and / or S160 based on the first information and the second information.

[0221] Regarding how the STA determines the type of the TB PPDU transmitted on P160 and / or S160, please refer to the description of how the AP indicates the type of the TB PPDU transmitted on P160 and / or S160 in S610, which will not be repeated here.

[0222] In one implementation, since the specific resources (RU or MRU) allocated to the STA are located in P160 and / or S160, in practice the STA needs to jointly determine the type of TB PPDU transmitted on P160 and / or S160 based on the first information, the second information (which may also include information in the special user information field) and the information #A in the user information field corresponding to the STA.

[0223] Taking Table 5 as an example, if the STA parses the trigger frame to obtain the first information as 0, the second information is 01, and the information A carried in the user information field of the STA indicates P160, based on the above conditions, the STA only needs to jointly determine to transmit the EHT PPDU on P160 (or on the resources corresponding to the STA), and there is no need to pay attention to S160; for example, if the first information indicates 1, the second information is 01, and the information A carried in the user information field of the STA indicates S160, based on the above conditions, the STA only needs to jointly determine to transmit the UHR PPDU on S160 (or on the resources corresponding to the STA), and there is no need to pay attention to P160.

[0224] In another implementation, the STA may determine a User Information field variant corresponding to the STA based on the first information carried in the common information field, the version and / or uplink bandwidth corresponding to at least one special user information field, and information A in the User Information field corresponding to the STA. The STA may further parse the User Information field corresponding to the STA based on the frame structure of the determined User Information field variant. In this application, the STA's determination of the type of the TB PPDU transmitted on P160 and / or S160 and the STA's determination of the User Information field variant corresponding to the STA may be interchangeable implementations and are not limited thereto.

[0225] Optionally, the method further includes:

[0226] S640: The STA sends a TB PPDU to the AP. Correspondingly, the AP receives the TB PPDU from the STA.

[0227] For S640, please refer to the description in S540 and will not be repeated here.

[0228] Another indication method is described below in conjunction with FIG7 . Method 700 shown in FIG7 differs from method 600 in that two additional pieces of information are added: one piece of information indicates the type of TB PPDU transmitted at P160, and the other piece of information indicates the type of TB PPDU transmitted at S160. Method 700 is described below.

[0229] Fig. 7 is a schematic diagram of a communication method 700 proposed in an embodiment of the present application. The method 700 includes the following steps.

[0230] S710, the AP generates a trigger frame, the trigger frame includes a common information field, second information and third information, the common information field includes first information, wherein the first information and the second information jointly indicate that one of the HE PPDU, EHT PPDU and UHR PPDU is transmitted on P160, and the third information indicates that one of the EHT PPDU and UHR PPDU is transmitted on S160.

[0231] Optionally, the first information is carried in the first field of the common information field. For example, the first information is a first value, indicating that the TB PPDU transmitted on P160 is a PPDU of a later HE version, and the first information is a second value, indicating that the TB PPDU transmitted on P160 is a HE PPDU.

[0232] It should be understood that the present application does not impose any specific restrictions on the name and length of the first field. For example, the name of the first field is the HE / EHT P160 field, and the first field is a field with a length of 1 bit.

[0233] Optionally, the first information may also be carried in multiple fields in the common information field, that is, the first information is jointly indicated by multiple fields.

[0234] Optionally, the second information or the third information may be carried in one or more fields of the public information field, or the second information or the third information may also be carried in one or more fields of the user information field.

[0235] For ease of understanding, the following takes the case where the first information, the second information, and the third information are all 1-bit information, and the first value of the first information is 0 and the second value is 1 as an example to provide an example of a table that the AP may refer to when indicating the type of TB PPDU transmitted on P160 and / or S160. For details, see Table 9 and Table 10.

[0236] Table 9

[0237] Table 10

[0238] Specifically, based on Table 9, the AP may indicate that the HE PPDU is transmitted on P160 by setting the first information to 1 and the second information to 1. Alternatively, the AP may indicate that the EHT PPDU is transmitted on P160 by setting the second information to 0 and the second information to 0. Alternatively, the AP may indicate that the UHR PPDU is transmitted on P160 by setting the second information to 0 and the second information to 1.

[0239] It can be understood that when the first information is 1, it is clear that the TB PPDU transmitted on P160 is a HE PPDU. Then, the second information in Table 9 can be set arbitrarily, that is, the STA does not need to pay attention to the second information when making a determination.

[0240] Specifically, based on Table 10, the AP may indicate that the EHT PPDU is transmitted at S160 by setting the third information to 0. Alternatively, the AP may indicate that the UHR PPDU is transmitted at S160 by setting the third information to 1.

[0241] S720: The AP sends a trigger frame to the STA. Correspondingly, the STA receives the trigger frame from the AP.

[0242] For S720, please refer to the description in S520 and will not be repeated here.

[0243] S730 : The STA determines the type of the TB PPDU transmitted at P160 based on the first information and the second information, and / or determines the type of the TB PPDU transmitted at S160 based on the third information.

[0244] Regarding how the STA determines the type of the TB PPDU transmitted on P160 and / or S160, please refer to the description of how the AP indicates the type of the TB PPDU transmitted on P160 and / or S160 in S710, which will not be repeated here.

[0245] In one implementation, since the specific resources (RU or MRU) allocated to the STA are located in P160 and / or S160, in practice the STA needs to jointly determine the type of TB PPDU transmitted on P160 based on the first information, the second information and the information #A in the user information field corresponding to the STA, and / or jointly determine the type of TB PPDU transmitted on S160 based on the third information and the information #A in the user information field corresponding to the STA.

[0246] Taking Table 9 and Table 10 as an example, if the STA parses the trigger frame to obtain the information A carried in the user information field of the STA indicating P160, and the first information obtained is 0 and the second information is 0, then based on the above conditions, the STA only needs to jointly determine to transmit the EHT PPDU on P160 (or on the resources corresponding to the STA), and there is no need to pay attention to the third information; for example, if the STA parses the trigger frame to obtain the information A carried in the user information field of the STA indicating S160, and the third information is 1, based on the above conditions, the STA only needs to determine to transmit the UHR PPDU on S160 (or on the resources corresponding to the STA), and there is no need to pay attention to the first information and the second information.

[0247] In another implementation, the STA may determine a User Information field variant corresponding to the STA based on the first information carried in the common information field, the version and / or uplink bandwidth corresponding to at least one special user information field, and information A in the User Information field corresponding to the STA. The STA may further parse the User Information field corresponding to the STA based on the frame structure of the determined User Information field variant. In this application, the STA's determination of the type of the TB PPDU transmitted on P160 and / or S160 and the STA's determination of the User Information field variant corresponding to the STA may be interchangeable implementations and are not limited thereto.

[0248] Optionally, the method further includes:

[0249] S740: The STA sends a TB PPDU to the AP. Correspondingly, the AP receives the TB PPDU from the STA.

[0250] For S740, please refer to the description in S540 and will not be repeated here.

[0251] It should be understood that the method 500 shown in FIG. 5 can be considered a method for indicating the type of a TB PPDU transmitted on P160 and / or S160, which is compatible with the meaning of the existing HE / EHT P160 field. In practical applications, the first information can be decoupled from the meaning of the existing HE / EHT P160 field, and the type of the TB PPDU transmitted on P160 and / or S160 can be indicated based on the first information in the common information field and information related to the special user information field. Among them, the information related to the special user information field in the trigger frame includes at least one of the following information: the number of special user information fields, part of the information in the special user information field (for example, the corresponding uplink bandwidth and / or version information, for example, the uplink bandwidth can be indicated by UL BW and / or UL BW Extended, and the version information can be indicated by the physical layer version identification field), a combination of certain information in multiple special user information fields (for example, a combination of corresponding uplink bandwidths), the order of multiple special user information, additional entries added to the special user information field (for example, a column corresponding to P160 in Table 5), and an association between the uplink bandwidth corresponding to the special user information field and the master-slave frequency domain position.

[0252] For example, if the meaning of the existing HE / EHT P160 field is unbound, the meanings corresponding to the first information being 0 and 1 in the above text may be swapped.

[0253] It should also be understood that the method shown in FIG7 is a method for indicating the type of TB PPDU transmitted on P160 and / or S160, which is proposed based on compatibility with the meaning of the existing HE / EHT P160 field. In actual applications, the first information can also be decoupled from the meaning of the existing HE / EHT P160 field, and a joint indication can be performed based on the first information in the common information field and one or more additional bits of information.

[0254] For example, if the first information is unbound from the meaning of the existing HE / EHT P160 field, Table 5 can be transformed into Table 11. As can be seen, in Table 11, the first information is unbound from the meaning of the existing HE / EHT P160 field.

[0255] Table 11

[0256] Optionally, the application itself may also combine the methods proposed in the embodiments of the present application for indication, for example, the above-mentioned method 500 and method 700 are combined for indication, and the present application does not limit this.

[0257] It should also be understood that the embodiments of the present application are described using the example of different types of TB PPDUs being transmitted on P160 and S160. In actual applications, three or even more types of TB PPDUs may be transmitted on P160 and S160, for example, supporting the transmission of three different types of TB PPDUs on P80, S80, and S160, respectively. The present application does not limit the granularity of PPDU transmission. As long as different types of TB PPDUs are transmitted in different frequency ranges, the method provided in the present application can be used to indicate the type of TB PPDU transmitted in different frequency ranges. For example, based on the above method, different types of TB PPDUs can be transmitted on the low frequency 80 of P160 and S160 and the high frequency 80 of S160, respectively. For another example, based on the above method, different types of TB PPDUs can be transmitted on the low frequency 80 of P40, S40, S80, and P160 and the high frequency 80 of S160, respectively. Examples are not given here one by one.

[0258] The solution proposed in this application can be applied to scenarios where A-PPDU exists or scenarios where A-PPDU does not exist. For scenarios where A-PPDU does not exist, the indication of non-A-PPDU can be achieved by reducing the entries or combinations corresponding to the A-PPDU scenarios. For example, the number of bits corresponding to the newly added information in the table containing the newly added bit information (e.g., Table 5) can be reduced to reduce the entries or combinations corresponding to the A-PPDU scenarios in the above table. Alternatively, the entries corresponding to the A-PPDU scenarios in the table not containing the newly added bit information (e.g., Table 2) can be set as Reserved entries (e.g., the descriptions corresponding to the second to fifth rows in Table 2 are set as Reserved) to reduce the entries or combinations corresponding to the A-PPDU scenarios. In addition, the absence of a special user information field in the non-A-PPDU scenario indicates that the transmitted non-A-PPDU is an HE PPDU. If a special user information field appears (which can be notified in the common information field or obtained by reading the special user information field), the transmitted non-A-PPDU is considered to be the PPDU of the version corresponding to the special user information field. For example, there is a 2-bit bitmap indicating EHT and UHR in the public information field, 11 indicates that there is no corresponding special user information field, then the public information field and the user information field both correspond to HE; 10 indicates that the EHT special user information field exists, then the public information field and the user information field both correspond to EHT; 01 indicates that the UHR special user information field exists, then the public information field and the user information field both correspond to UHR, 0 and 1 are just examples, and this application is not limited.

[0259] Optionally, the above method can also be combined with the RU allocation field, PS160 field, and other fields in the user information field to jointly complete the indication.
