Description

Technical Field

[0001] This application relates to the field of communications, and more particularly, to a communication method and a communication device. Background Art

[0002] Wireless local area network (WLAN) has gone through multiple generations so far. For example, it supports IEEE 802.11 related standards such as 802.11ax, 802.11be, 802.11bn, etc. Among them, the 802.11ax standard is called High Efficient (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).

[0003] Currently, in the 802.11be standard, the trigger frame further supports the triggering of EHT TB PPDU on the basis of supporting the triggering of HE Trigger-based (TB) physical layer protocol data unit (PPDU). With the evolution of the standard, how to indicate or trigger more types of PPDUs based on the trigger frame needs to be further studied. Summary of the Invention

[0004] Embodiments of this application provide a communication method and a communication device, which can support the triggering of multiple types of PPDUs.

[0005] In a first aspect, a communication method is provided. This method can be executed by a station, or can also be executed by a component (such as a chip or a circuit) of the station, and this is not limited. For ease of description, the example of the station execution is used for illustration.

[0006] This method may include: the station receives a trigger frame from an access point, the trigger frame includes 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 primary 160-channel and / or the secondary 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.

[0007] In the above technical solution, without adding additional indication information, the station determines the type of the TB PPDU transmitted on the primary 160-channel and / or the secondary 160-channel by combining the information that the special user information field itself needs to carry.

[0008] In certain implementations of the first aspect, determining the type of the TB PPDU transmitted on the primary 160-channel and / or the secondary 160-channel includes: the first information is a first value, the first value indicating that the TB PPDU transmitted on the primary 160-channel is a PPDU after the high-efficiency HE version, at least one special user information field includes 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 after the HE version, and the station determines to transmit the PPDU of the first version on the primary 160-channel and / or transmit the PPDU of the second version on the secondary 160-channel.

[0009] It should be understood that in this solution, there are special user information fields of the first version and the second version, that is, the AP indicates to transmit PPDUs of different versions in the two versions on the primary 160-channel and the secondary 160-channel respectively. Which version of the PPDU the STA specifically transmits still needs to be further determined by the STA based on the meaning of the bandwidth combination corresponding to the first bandwidth and the second bandwidth.

[0010] 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 secondary 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 station determines the type of the TB PPDU transmitted on the primary 160-channel and / or the secondary 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.

[0011] In the above technical solution, the type of the TB PPDU transmitted on the primary 160-channel and / or the secondary 160-channel can also be determined in combination with the order of the special user information fields.

[0012] Exemplarily, the order can be in ascending order, descending order, or an order of a certain specific rule. For example, it is stipulated that the order is in ascending order. If the special user information field of the first version is before the special user information field of the second version, it indicates that the STA transmits the PPDU of the first version on the primary 160-channel and / or transmits the PPDU of the second version on the secondary 160-channel. Another example, it is stipulated that the order is in descending order. If the special user information field of the first version is placed before the special user information field of the second version, it indicates that the STA transmits the PPDU of the second version on the primary 160-channel and / or transmits the PPDU of the first version on the secondary 160-channel.

[0013] In certain implementations of the first aspect, the station determines the type of the TB PPDU transmitted on the primary 160 MHz channel and / or the secondary 160 MHz 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 primary 160 MHz channel is a PPDU after the high-efficiency HE version, 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 PPDU of the first version on the primary 160 MHz channel, and / or transmit the PPDU of the second version on the secondary 160 MHz channel, wherein the special user information field of the first version is before the special user information field of the second version.

[0014] In certain implementations of the first aspect, the station determines the type of the TB PPDU transmitted on the primary 160 MHz channel and / or the secondary 160 MHz 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 primary 160 MHz channel is a PPDU after the high-efficiency HE version, 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 PPDU of the first version on the primary 160 MHz channel, and / or transmit the PPDU of the second version on the secondary 160 MHz channel, wherein the uplink bandwidth of the special user information field of the first version is a third bandwidth, and 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 MHz channel, and the fourth bandwidth is associated with the secondary 160 MHz channel.

[0015] It can be understood that in this solution, some uplink bandwidths can be associated with the primary 160 MHz channel, and some other uplink bandwidth values can be associated with the secondary 160 MHz channel. Among them, if the uplink bandwidth corresponding to a certain special user information field is associated with the primary 160 MHz channel, the PPDU of the version corresponding to the special information user field is sent on the primary 160 MHz channel, and if the uplink bandwidth corresponding to a certain special user information field is associated with the secondary 160 MHz channel, the PPDU of the version corresponding to the special information user field is sent on the secondary 160 MHz channel.

[0016] In certain implementations of the first aspect, the actual uplink bandwidths corresponding to the special user information field of the first version and the special user information field of the second version are 160 MHz.

[0017] 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 PPDU of the first version and the PPDU of the second version.

[0018] In certain implementations of the first aspect, the station determines the type of the TB PPDU transmitted on the primary 160 MHz channel and / or the secondary 160 MHz 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 second value, the second value indicates that the TB PPDU transmitted on the primary 160 MHz channel is an efficient HE PPDU, and at least one special user information field only includes the special user information field of the first version, where the first version is any version after the HE version. The station determines to transmit an HE PPDU on the primary 160 MHz channel and / or transmit the PPDU of the first version on the secondary 160 MHz channel.

[0019] In the above technical solution, there is only the special user information field of the first version, so it is indicated to transmit the PPDU of the first version on the secondary 160 MHz channel.

[0020] In certain implementations of the first aspect, the station determines the type of the TB PPDU transmitted on the primary 160 MHz channel and / or the secondary 160 MHz 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 primary 160 MHz channel is a PPDU after the efficient HE version, at least one special user information field only includes 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. The station determines to transmit the PPDU of the first version on the primary 160 MHz channel, or the uplink bandwidth corresponding to the special user information field of the first version is equal to 320 MHz. The station determines to transmit the PPDU of the first version on the primary 160 MHz channel and / or the secondary 160 MHz channel.

[0021] In the above technical solution, there is only the special user information field of the first version, so it is indicated to transmit the PPDU of the first version on the primary 160 MHz channel.

[0022] It can be understood that in this solution, for the station, there is no 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 320 MHz, the AP will not allocate resources for the STA on the secondary 160 MHz channel.

[0023] In certain implementations of the first aspect, any one of the at least one special user information field includes an associated identification AID12 field and a physical layer version identification field, where the value of the AID12 field is 2007, and the physical layer identification field indicates the version corresponding to the special user information field.

[0087] Next, the technical solutions in the embodiments of the present application will be described with reference to the drawings. Obviously, the described embodiments are a part of the embodiments of the present application, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0088] Before introducing the embodiments of the present application, the following points are first explained.

[0089] First, in the present application, if there is no special explanation and logical conflict, the terms and / or descriptions between different embodiments are consistent and can be mutually referred to, and the technical features in different embodiments can be combined to form new embodiments according to their internal logical relationships.

[0090] It can be understood that some optional features in the embodiments of the present application may, in some scenarios, not depend on other features, or may be combined with other features in some scenarios, without limitation.

[0091] It can be understood that the solutions in the embodiments of the present application can be used in combination, and the explanations or descriptions of each term and the similar operations or steps that appear in the embodiments can be referred to or explained with each other in each embodiment. The present application does not make any limitations in this regard.

[0092] Second, in the present application, "at least one" means one or more, and "a plurality" means two or more. "And / or" describes the association relationship of associated objects and indicates that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone, where A and B can be singular or plural. In the written description of the present application, the character " / " generally represents an "or" relationship between the front and back associated objects. "At least one (item)" or its similar expression refers to any combination of these items, including any combination of single item (item) or multiple items (items). For example, at least one (item) of a, b, and c can represent: a, or, b, or, c, or, a and b, or, a and c, or, b and c, or, a, b, and c. Where a, b, and c can be single or multiple respectively.

[0093] Third, in the present application, "first", "second", and various numerical numbers are for the convenience of description and are not used to limit the scope of the embodiments of the present application. For example, to distinguish different messages, etc., rather than for describing a specific order or sequence. It should be understood that the objects described in this way can be interchanged under appropriate circumstances so as to be able to describe the solutions other than the embodiments of the present application.

[0094] Fourth, in the present application, the terms "comprise" and "have" and any of their variations are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0095] Fifth, in the present application, "indicate" may include direct indication and indirect indication. When describing that a certain indication information indicates A, it may include that the indication information directly indicates A or indirectly indicates A, and it does not mean that A must be carried in the indication information.

[0096] Sixth, in this application, "sending information to XX (device)" can be understood as the destination of the information being the device. It can include directly or indirectly sending information to the device. "Receiving information from XX (device), or receiving information coming from XX (device)" can be understood as the source of the information being the device, and it can include directly or indirectly receiving information from the device. Necessary processing may be performed on the information between the source and the destination of the information sending, such as format change, etc., but the destination can be understood as the valid information from the source.

[0097] Sixth, in this application, the so-called "field" can generally refer to a part of information, and "field" can also be called "domain" or "field", etc. And the name of the field in this application is just an example, and in specific implementation, it can also be other names, and this application does not make specific limitations on this.

[0098] Seventh, in the schematic diagrams in the attached drawings of the specification of this application, the arrows or boxes shown by dashed lines represent optional steps or optional modules.

[0099] The technical solution provided by the embodiments of this application can be applicable to wireless local area network (WLAN) scenarios. WLAN has gone through multiple generations so far. For example, it supports 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 efficient (HE), the 802.11be (Wi-Fi 7) standard is called extremely high throughput (EHT), the 802.11bn (Wi-Fi 8) standard is called ultra-high reliability (UHR), and for the standards before HT, such as 802.11a / b / g, etc., they are collectively called Non-HT (non-high throughput). In addition, what this application provides can also be applied to wireless personal area network systems based on ultra-wide band (UWB), such as IEEE 802.15 series standards, and can also be applied to sensing systems, such as IEEE 802.11bf series standards.

[0100] Although the embodiments of the present application mainly illustrate by taking the deployment of a WLAN network, especially a network applying the IEEE 802.11 system standard as an example, those skilled in the art can easily understand that all aspects involved in the embodiments of the present application can be extended to other networks adopting various standards or protocols. For example, high performance radio local area network (HIPERLAN), wireless wide area network (WWAN), wireless personal area network (WPAN), or other networks known now or developed in the future. Therefore, regardless of the coverage range and wireless access protocol used, all aspects provided by 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 vehicle to X (V2X). 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), worldwide interoperability for microwave access (WiMAX) communication system, fifth generation (5G) communication system, and future sixth generation (6G) communication system, etc.

[0101] The above-mentioned communication systems applicable to the present application are only illustrative examples, and the communication systems applicable to the present application are not limited thereto. This is uniformly stated here and will not be elaborated further below.

[0102] A WLAN may include multiple basic service sets (BSS), and the network nodes in a BSS are stations (STA) and access points (AP). Each BSS may contain one AP and multiple STAs associated with the AP.

[0103] The AP in the embodiments of the present application can also be referred to as a wireless access point or hotspot, etc. The AP is an access point for mobile users to enter the wired network, mainly deployed in homes, inside buildings, and inside campuses, with a typical coverage radius of dozens of meters to hundreds of meters. Of course, it can also be deployed outdoors. The 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. By way of example, the AP can be a device supporting the 802.11ax protocol and a device supporting the next-generation Wi-Fi protocol of 802.11ax. Further, the AP can support the next generation of 802.11be, such as Wi-Fi 8, UHR, etc., one or more WLAN standards of the 802.11 series of protocols or subsequent versions. For example, the AP in the present application can be a HE STA or an EHT STA, and can also be a STA applicable to a future generation of Wi-Fi standards.

[0104] 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 supporting Wi-Fi communication function, a tablet computer supporting Wi-Fi communication function, a set-top box supporting Wi-Fi communication function, a smart TV 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. By way of example, the STA can be a device supporting the 802.11ax standard and a device supporting the next-generation Wi-Fi protocol of 802.11ax. Further, the AP can support the next generation of 802.11be, such as Wi-Fi 8, UHR, etc., one or more WLAN standards of the 802.11 series of protocols or subsequent versions.

[0105] In an embodiment of the present application, as an example structure, a STA or an AP includes a hardware layer, an operating system layer running on top of 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 a memory (also referred to as main memory). The operating system can be any one or more computer operating systems that implement service processing through processes. For example, Linux operating system, Unix operating system, Android operating system, iOS operating system, or Windows operating system, etc. The application layer includes applications such as a browser, an address book, a word processing software, and an instant messaging software. The above examples do not limit the specific implementation form of the execution entity of the method provided in the embodiments of the present application. As long as it can communicate according to the method provided in the embodiments of the present application by running a program that records the code of the method provided in the embodiments of the present application. For example, the execution entity of the method provided in the embodiments of the present application can be a STA or an AP, or a functional module in a STA or an AP that can call and execute the program.

[0106] In addition, various aspects or features of the present application can be implemented as a method, an apparatus, or an article of manufacture using standard programming and / or engineering techniques. The term "article of manufacture" used in the present application covers a computer program accessible from any computer-readable device, carrier, or medium. For example, computer-readable media can include, but are not limited to: magnetic storage devices (such as hard disks, floppy disks, or magnetic tapes, etc.), optical discs (such as compact discs (CDs), digital versatile discs (DVDs), etc.), smart cards, and flash memory devices (such as erasable programmable read-only memories (EPROMs), cards, sticks, or key drives, etc.). In addition, the various storage media described herein can represent one or more devices and / or other machine-readable media for storing information. The term "machine-readable media" can include, but is not limited to, wireless channels and various other media capable of storing, containing, and / or carrying instructions and / or data.

[0107] Figure 1 is a schematic diagram of the network architecture of the wireless local area network applicable to the embodiments of the present application. As Figure 1 shown, an AP can be associated with one or more STAs, that is, an AP can communicate with one or more STAs. As Figure 1 shown, the network architecture of the wireless local area network can also include multiple APs, and different APs can also communicate with each other. For example Figure 1As shown, the figure shows AP#1 and AP#2, as well as STAs 11 and 12 associated with AP#1. Among them, data can be transmitted between AP#1 and STA 11 or STA 12, data can be transmitted between STA 11 and STA 12, and communication can also be carried out between AP#1 and AP#2.

[0108] It should be understood that Figure 1 This is only exemplary and should not impose limitations on the network architecture of the wireless local area network applicable to this application. For example, the network architecture may also include more APs, and each AP may also be associated with more STAs. This is not limited in the embodiments of this application.

[0109] Figure 2 It is a schematic diagram of the frame structure of a trigger frame in the 802.11ax standard (HE). This trigger frame contains a Common Info field and a User Info List field. Among them, the Common Info field contains common information applicable to all STAs indicated in the trigger frame, and the User Info List field contains multiple UserInfo fields. Each UserInfo field corresponds to information applicable to one STA. In the UserInfo field, the association identification 12 (AID12) represents the association identification 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 UserInfo field to send a Trigger-based (TB) physical layer protocol data unit PPDU (physical layer protocol dataunit) on the allocated RU.

[0110] In order to enable the trigger frame to have the function of triggering an EHT TB PPDU, the 802.11 standard has updated the trigger frame. However, this update does not redefine a dedicated trigger frame for triggering an EHT TB PPDU, but shares it with the HE trigger frame, that is, the trigger frame evolves to be able to trigger an HE TB PPDU or an EHT TB PPDU.

[0111] It should be noted that for the Common Info field of the trigger frame in the 802.11be standard, non-EHT HE non-AP STAs will understand the Common Info field as a HE variant common information field (that is, according to Figure 2Interpret the common information field). If B54 and B55 in the common information field are equal to 1, the EHT non-AP STA interprets the common information field as a HE variant common information field; otherwise, it interprets the common information field as an EHT variant common information field (i.e., as described below Figure 3 Interpret the common information field).

[0112] Figure 3 is a schematic diagram of the frame structure of a trigger frame that is an EHT variant. The trigger frame includes a Common Information field and a User Info List field. The specific fields included in the Common Information field are detailed in Figure 3 , and the specific meanings of the fields in the common information field can be referred to the description in the protocol. The User Info List field contains multiple User Info fields, and each User Info field includes an AID12 field. Among them, the value of the AID12 field in the first User Info field is 2007, and some common information is carried after the AID12 field of this User Info field. Although the first User Info field is a User Info field, it carries common information, so the first User Info field can be called a special User Info field. It should be noted that after the STA is associated with the AP, it will obtain an AID. When triggering the EHT STA, the AP will not assign the AID of any STA to 2007. Therefore, the STA will not have any ambiguity when receiving a trigger frame with the AID12 value of 2007. Starting from the second User Info field, the AID12 field of this User Info field specifically points to a STA user, and this User Info field contains the information that the pointed STA user needs to read. The Resource Unit Allocation field (RU allocation) and the Primary / Secondary 160 field in this User Info field jointly indicate the specific location of the resource unit (RU) or multi-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 * 996 tones, if the PS160 field is set to 0, it means that the RU or MRU is allocated to P160; 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. To facilitate the understanding of the solution of the embodiments of the present application, the UL BW Extension field and the PHY Version Identifier field included in the special User Info field are briefly introduced here.

[0113] Among them, the uplink bandwidth expansion 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. Among them, both the uplink bandwidth expansion field and the uplink bandwidth field occupy 2 bits (bit). Specifically, as shown in Table 1, when the uplink bandwidth field takes the value of 0 and the uplink bandwidth expansion field takes the value of 0, it indicates 20 MHz; when the uplink bandwidth field takes the value of 1 and the uplink bandwidth expansion field takes the value of 0, it indicates 40 MHz; when the uplink bandwidth field takes the value of 2 and the uplink bandwidth expansion field takes the value of 0, it indicates 80 MHz; when the uplink bandwidth field takes the value of 3 and the uplink bandwidth expansion field takes the value of 1, it indicates 160 MHz; when the uplink bandwidth field takes the value of 3 and the uplink bandwidth expansion field takes the value of 2, it indicates 320 MHz-1; when the uplink bandwidth field takes the value of 3 and the uplink bandwidth expansion field takes the value of 3, it indicates 320 MHz-2.

[0114] Among them, the physical layer version identifier in the special user information field is used to indicate which version the special user information field belongs to. The trigger frame in the 802.11be standard only contains one special user information field, and the physical layer version identifier field in this special user information field is used to indicate that this special user information field is a special user information field of the EHT version.

[0115] It can be understood that the special user information field can be regarded as a supplement to the common information field. For example, when triggering the STA to send an EHT PPDU, the STA also needs to read the relevant fields in the special user information field of the EHT version to obtain the complete parameters for sending the EHT PPDU, so as to realize the sending of the EHT PPDU.

[0116] In addition, Figure 3 The number of bits occupied by the fields included in the common information field and the user information list field are respectively marked. Here, only an example is given. For example, the B0 to B11 corresponding to the AID12 field in User Information 1 indicates that the AID12 field is the first 12 bits in the User Information 1 field.

[0117] Table 1

[0118]

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

[0120] However, it should be noted that Figure 4 this is an example with a 320 MHz channel. For example, if the channel is a 160 MHz channel, then there is no S160. If the channel is an 80 MHz channel, then there is no S80, and the same applies to others. Unless otherwise specified in the following text, a 320 MHz channel is used as an example for description.

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

[0122] As Figure 3 shown, in the HE / EHT P160 field (i.e., B54 of the common information field) of the common information field of the EHT variant, 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 requested TB PPDU 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 requested TB PPDU in P160 is an HE TB PPDU.

[0123] It can be seen that the 802.11be standard enables the trigger frame to further support the triggering of EHT TB PPDU on the basis of supporting the trigger HE TB PPDU. There are more versions after EHT. For example, for UHR users, it may be possible to transmit PPDUs of HE / EHT / UHR types on P160 in the future, and EHT / UHR type PPDUs can be transmitted on S160. However, it is not clear how to support the triggering of more types of PPDUs for UHR users or users of higher versions after UHR.

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

[0125] Figure 5 It is a schematic diagram of a communication method 500 proposed by 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. Among them, 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 are used to indicate the type of TB PPDU transmitted on P160 and / or S160.

[0127] It can be understood that the PPDU involved in the present application is a TB PPDU, and details will not be repeated hereinafter.

[0128] Optionally, the first information is carried in the first field of the common information field. By way of example, the first information is a first value, indicating that the TB PPDU transmitted on P160 is a PPDU after the 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 the present application does not make specific limitations on the name and length of the first field. By way of example, the length of the first field can be 1 bit, such as the B54 bit of the common 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; or the first value can be 1 and the second value can be 0.

[0130] Optionally, the first information can also be carried in multiple fields of the common information field, that is, the first information is indicated jointly 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. Among them, 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, the STA determines whether there is a special user information field that can be read through the user information list field, or a 1-bit special user information field identification field in the common information field. Optionally, to increase robustness, relevant indication information can be further added to the common information field, for example, indicating which version of the special user information field exists in the form of a bitmap, or, it can also indicate which version of the special user information field exists in the form of an index, correspondence, etc.

[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, at least one special user information field included in the trigger frame is the special user information field corresponding to one or more versions among EHT, UHR, and multiple versions after future 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), or, it can also be indicated separately by the uplink bandwidth extension field in the special user information field. This application does not make any limitations in this regard.

[0135] Next, a detailed description will be given on how the AP indicates the type of TB PPDU that can be transmitted on P160 and / or S160 to the STA based on the first information and the version and / or uplink bandwidth corresponding to at least one special user information field.

[0136] For ease of understanding, the following description will be given by taking the meanings when the first information takes the first value and the second value in the above text as examples.

[0137] (a) If the AP sets the first information to the first value, the trigger frame only includes 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 it is indicated that the STA transmits the PPDU of the first version on P160.

[0138] Among them, indicating to transmit the PPDU of the first version on P160 can also be alternatively described as "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, then the STA can consider that it can only transmit the PPDU on P160 and will not transmit the PPDU on S160.

[0140] It should also be noted that in this application, if the AP does not set the special user information field of a certain version in the trigger frame, the STA can consider that the PPDU of this version cannot be transmitted in both 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 only includes 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 it is indicated that the STA transmits the PPDU of the first version on P160 and / or S160.

[0142] For the above solutions (a) and (b), it can also be understood that if the AP sets the first information to the first value and the trigger frame only includes the special user information field of the first version, then it is indicated that the STA transmits the PPDU of the first version on P160 and / or S160. That is to say, when the STA determines the specific information indicated, it 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 PPDU of the first version is transmitted on P160 and / or S160.

[0143] However, it should be noted here 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 for the STA on 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 it is indicated to the STA to transmit the PPDU of the first version on P160 and / or transmit the PPDU of the second version on S160.

[0145] It should be understood that in this solution, there are special user information fields of the first version and the second version, that is, the AP indicates to transmit the PPDUs of different versions in the two versions 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 version information corresponding to P160 and S160. For example, a bandwidth combination consisting of {20 MHz, 40 MHz} is given a meaning, which indicates that a PPDU of version #1 is transmitted on P160 and a PPDU of version #2 is transmitted on S160. Among them, version #1 is the version corresponding to the special user information field with an indicated uplink bandwidth of 20 MHz, and version #2 is the version corresponding to the special user information field with an indicated uplink bandwidth of 40 MHz. Based on the above definition, if the AP wants to indicate that a PPDU of the first version is transmitted on P160 and a PPDU of the second version 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 clarify the meaning of the bandwidth combination corresponding to the first bandwidth and the second bandwidth. By way of example, the meaning corresponding to the first bandwidth and the second bandwidth can be predefined or specified by the protocol.

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

[0149] Then, in this solution, the more logical first bandwidth and second bandwidth are 160 MHz and 320 MHz. Among them, the physical meaning that 320 MHz can be interpreted as is 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 a special user information field of the first version and a special user information field of the second version, it is also possible not to pay attention to the first bandwidth and the second bandwidth, and directly default to indicating that the STA transmits the PPDU of the first version on P160 and / or transmits the PPDU of the second version on S160.

[0151] It should be noted that in the prior art, an EHT STA can distinguish whether to read the common information field according to HE or EHT by the presence or absence 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. However, this method is not compatible with the A-PPDU scenario. For example, when HE / EHT P160 corresponds to HE, but there is a special user information field, and this is the A-PPDU scenario at this time, then S160 should read the common information field according to EHT.

[0152] If the A-PPDU scenario is not considered (the scenario in which there is at most one special user information field), similarly, it can be distinguished by the presence or absence of a special user field of a certain version (for example, by reading the special user information field, or by 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, then the common information field is read according to HE, otherwise the common information field is read according to the variant corresponding to the version of the special user information field. In addition, B54 may not be combined. The STA can determine how to read the common information field and its own user information field only by the presence or absence of the special user field. Because when there is no A-PPDU, there is at most one special user field in the trigger frame. Then, when there is no special user information, it is read according to HE, and when there is one special user information, it is read according to the variant corresponding to the 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 distinguishing how to read the common information field can be based on the method of identifying the variant of the special user information field. It's just that the above method does not need to read the special user information field and can identify how to read the common information field faster.

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

[0155] For example, the order can be in ascending order, descending order, or an order with a specific rule. For example, it is stipulated that the order is in ascending order. If the special user information field of the first version is arranged before the special user information field of the second version, it indicates that the STA transmits the PPDU of the first version on P160 and / or transmits the PPDU of the second version on S160. Another example, if it is stipulated that the order is in descending order and the special user information field of the first version is arranged before the special user information field of the second version, it indicates that the STA transmits the PPDU of the second version on P160 and / or transmits the PPDU of the first version on S160.

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

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

[0158] Optionally, in solution (c1), the type of the TB PPDU transmitted on P160 and / or S160 can also be jointly indicated by combining the uplink bandwidth values corresponding to the special user information fields.

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

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

[0161] Optionally, the existing uplink bandwidth values 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 in Table 1 having a value of 0 and the UL BWExtension field having a value of 1 is modified to 160, and this 160 is associated with S160.

[0162] Similarly, in solution (c), there will be some problems if the uplink bandwidths of the special user information fields of the first version and the second version are both set to the actual uplink bandwidth of 160 MHz. However, based on solution (c2), even if the special user information fields of the first version and the second version are both set to 160 MHz, the AP can overcome the problems that occur in solution (c) by setting one of the two 160 MHz to be associated with P160 and the other to be associated with S160.

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

[0164] (d) If the AP sets the first information to the second value, and the second value indicates that the TB PPDU transmitted on P160 is a 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 a HE PPDU on P160, and / or transmit the PPDU of the first version on S160.

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

[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, and the first bandwidth indicated by the special user information field (for example, bandwidth #1 is 20 MHz) may not be the actual uplink bandwidth of the first version of the TB PPDU triggered. 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 that can be explained by 320 MHz is the uplink bandwidth of the A-PPDU composed of the HE version and the PPDU of the first version.

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

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

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

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

[0172] It should be noted that the first 5 rows corresponding to when the first piece of information is 0, and the 3 rows corresponding to when the first piece of information is 1 in Tables 2 to 4 are the same (corresponding to Solution (a) and Solution (b)). Among them, the first 4 rows of the first 5 rows corresponding to when the first piece of information is 0 correspond to Solution (a), and the 5th row corresponds to Solution (b); the first 2 rows of the 3 rows corresponding to when the first piece of information is 1 correspond to Solution (d), and the 3rd row corresponds to Solution (e).

[0173] The differences among Table 2, Table 3, and Table 4 are as follows: for Table 2, the last 2 rows corresponding to when the first piece of information is 0 correspond to Solution (c), the last 3 rows corresponding to when the first piece of information is 0 in Table 2 correspond to Solution (c1), and the last 2 rows corresponding to when the first piece of information is 0 in Table 2 correspond to Solution (c2).

[0174] Table 2

[0175]

[0176] Table 3

[0177]

[0178]

[0179] It should be noted that the uplink bandwidths of EHT and UHR in Table 3 are both set to 160 MHz. Since traditional EHT STAs may not have the ability to read the order, if the specified order is in ascending order and the special user information field of UHR is before the special user information field of EHT, then when an EHT STA reads a special user field with an AID of 2007 and the bandwidth is 160 MHz, it may consider the TB PPDU indicated by the AP to be an EHT PPDU transmitted on P160, thus conflicting with the transmission method indicated by the penultimate row corresponding to when the first piece of information is 0. At this time, the solution corresponding to the last row when the first piece of information is 0 can be used to replace the penultimate row: it can make traditional EHT STAs think that the uplink bandwidth of EHT is 320 MHz. In this case, as long as the AP does not allocate resources to traditional EHT STAs on P160, there will be no conflict. However, in this situation, the uplink bandwidth used by the STA to feedback the TB PPDU may be 320 MHz (i.e., the uplink bandwidth of the A-PPDU) or 160 MHz (the actual bandwidth of the EHT PPDU responded by the STA).

[0180] Table 4

[0181]

[0182]

[0183] It should be noted that S160 in Table 4 indicates that the uplink bandwidth corresponding to the special user information field indication is associated with Channel 160.

[0184] It should be noted that the uplink bandwidths of EHT and UHR in Table 4 are both set to 160 MHz. Since traditional EHT STAs may not have the ability to read S160, when an EHT STA reads a special user field with an AID of 2007 and a bandwidth of 160 MHz, it may consider that the TB PPDU indicated by the AP to be transmitted on P160 is an EHT PPDU, thus conflicting with the transmission method indicated by the penultimate row when the first information is 0. In this case, the scheme corresponding to the last row when the first information is 0 can be used to replace the penultimate row: the traditional EHT STA can be made to think that the uplink bandwidth of EHT is 320 MHz. At this time, as long as the AP does not allocate resources for the traditional EHT STA on P160, there will be no conflict. However, in this case, the uplink bandwidth of 320 MHz may need to be used when the STA feeds back the TB PPDU.

[0185] S520, the AP sends a trigger frame to the STA. Correspondingly, the STA receives the trigger frame from the AP.

[0186] After the STA receives the trigger frame, if it parses out a user information field in the trigger frame that matches its own AID, then the STA will send a TB PPDU on the specific resources (RU or MRU) allocated to it.

[0187] Exemplarily, the STA can jointly determine the location of the specific resources allocated to it based on the resource unit allocation (RU allocation) field in its own user information field and the information A carried in its own user information field (the specific meaning of information A can refer to Figure 3 the meaning of the primary and secondary 160 (PS160) field in). Among them, the specific resources allocated by the AP to the STA are located in P160 and / or S160.

[0188] Exemplarily, information A is carried in the second field of the user information field.

[0189] This application does not make specific restrictions on the name and length of the second field. Exemplarily, the name of the second field is the PS160 field, and the second field is a field with a length of 1 bit.

[0190] 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 at least one special user information field.

[0191] Regarding how the STA determines the type of the TB PPDU transmitted on P160 and / or S160, refer to the relevant description in S510 about how the AP indicates the type of the TB PPDU transmitted on P160 and / or S160 for details, which will not be elaborated here.

[0192] In one implementation, since the specific resources (RU or MRU) allocated to the STA are located on P160 and / or S160, in practice, the STA needs to jointly determine the type of the TB PPDU it transmits on P160 and / or S160 based on the first information carried in the common information field, the version corresponding to at least one special user information field, and / or the uplink bandwidth and the information A in the user information field corresponding to the STA.

[0193] Taking Table 2 as an example, if the first information indicates 0, the special user information field in the trigger frame only includes UHR, 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 UHR PPDU on P160 (or on the resources corresponding to the STA), and does not need to pay attention to S160; for another example, if the first information indicates 0, the special user information fields in the trigger frame include 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, 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 does not need to pay attention to P160.

[0194] In another implementation, the STA can jointly determine the User Info filed variant corresponding to the STA based on the first information carried in the common information field, the version corresponding to at least one special user information field, and / or the uplink bandwidth and the information A in the user information field corresponding to the STA. The STA can 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 implementation methods of the STA determining the type of the TB PPDU transmitted on P160 and / or S160 and the STA determining the user information field variant corresponding to the STA can be mutually replaced, and no limitation is made.

[0195] Optionally, the method further includes:

[0196] S540, the STA sends the TB PPDU to the AP. Correspondingly, the AP receives the TB PPDU from the STA.

[0197] Among them, the version corresponding to the TB PPDU is the version determined by the STA based on the information A carried in its own user information field in S530.

[0198] 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 the PPDU of its own version, and this application does not make any restrictions.

[0199] Taking Table 2 as an example to illustrate the bandwidth carried in the TB PPDU sent by the STA. 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. Based on the above conditions, the STA jointly determines to transmit the UHR TB PPDU (i.e., the TB PPDU sent by the STA) on S160. For example, the bandwidth carried in the UHR TB PPDU can be 320 MHz or 160 MHz.

[0200] The above has described Method 500 in detail. It can be seen that without adding additional indication information, this method indicates the type of TB PPDU transmitted on P160 and / or S160 to the STA by combining the number of special user information fields, the version information corresponding to the special user information fields, and the uplink bandwidth.

[0201] Next, in combination with Figure 6 and Figure 7 Two methods for indicating the type of TB PPDU transmitted on P160 and / or S160 are continued to be given. Figure 6 and Figure 7 The difference between the methods shown and Method 500 is that the following two methods require additional indication information (such as adding additional bit information) for indication. The following is a detailed description.

[0202] Figure 6 It is a schematic diagram of a communication method 600 proposed in an embodiment of this application. This method 600 includes the following steps.

[0203] S610, the AP generates a trigger frame, and the trigger frame includes a common information field and a second information. The common information field includes a first information, where the first information and the second information jointly indicate to transmit one of the EHT PPDU and the UHR PPDU on P160, and to transmit one of the EHT PPDU and the UHR PPDU on S160.

[0204] Optionally, the first information is carried in the first field of the common information field. By way of example, the first information is a first value indicating that the TB PPDU transmitted on P160 is a PPDU after the HE version, and the first information is a second value indicating that the TB PPDU transmitted on P160 is a HE PPDU.

[0205] It should be understood that the present application does not specifically limit the name and length of the first field. By way of 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.

[0206] 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.

[0207] Optionally, the second information may be carried in one or more fields of the common information field, or the second information may also be carried in one or more fields of the user information field.

[0208] For ease of understanding, the following gives several exemplary tables that an AP may refer to when the first information is 1-bit information, the first value of the first information is 0, and the second value is 1, to indicate the type of the TB PPDU transmitted on P160 and / or S160. See specifically Table 5, Table 6, Table 7, and Table 8.

[0209] Example 1: The second information is information with a length of 2 bits. The specific meaning jointly indicated by the first information and the second information is shown in Table 5.

[0210] Table 5

[0211]

[0212] Specifically, based on Table 5, the AP can set the first information to 1 to indicate the transmission of a HE PPDU on P160, and indicate one of the EHT PPDU and UHR PPDU transmitted on S160 through the corresponding value of the second information (i.e., the newly added 2 bits). Alternatively, the AP can set the first information to 0 to indicate the transmission of a PPDU after the HE version (i.e., one of the EHT PPDU and UHR PPDU) on P160. Since only the EHT PPDU and UHR PPDU can also be transmitted on S160, there are a total of 4 possible combinations of the situations on P160 and S160. The AP can further specifically indicate the types of the PPDUs transmitted on P160 and S160 through the corresponding 4 values of the second information.

[0213] It should be noted that the corresponding meanings when the second information in Table 5 takes different values are only examples. For example, when the first information is 1 and the second information is 10, it indicates that S160 corresponds to UHR; when the second information is 11, it indicates that S160 corresponds to EHT, and the meanings corresponding to 00 and 01 are reserved. The tables described later in this application are all exemplary descriptions, and the relevant parts will not be elaborated one by one.

[0214] Example 2: The second information is an information with a length of 1 bit. For the specific meanings jointly indicated by the first information and the second information, refer to Table 5.

[0215] Table 6

[0216]

[0217]

[0218] The difference between Table 6 and Table 5 is that the second information in Table 6 is a 1-bit information. Therefore, when the first information is 0, since the second information is a 1-bit information, it is impossible to define the 4 cases after the combination of the situations on P160 and S160 through 1 bit. Therefore, when the first information in Table 6 is 0, the descriptions corresponding to the second information being 0 and 1 can be the descriptions corresponding to any two of the values 00, 01, 10, and 11 when the first information in Table 5 is 0. Exemplarily, when the first information in Table 6 is 0 and the second information is 0 and 1, the corresponding descriptions are respectively the descriptions corresponding to 00 and 10 when the first information in Table 5 is 0, which will not be elaborated here.

[0219] Optionally, the above joint indication of the first information and the second information further includes the joint indication of the first information, the second information, and the special user information field to transmit one of the EHT PPDU and UHR PPDU on P160, and to transmit the PPDU after the HE version (i.e., one of the EHT PPDU and UHR PPDU) on S160.

[0220] Example 3: The second information is an information with a length of 1 bit. For the specific meanings jointly indicated by the first information, the second information, and the special user information field (whether it exists), refer to Table 7.

[0221] Table 7

[0222]

[0223] Specifically, based on Table 7, the AP can indicate the transmission of a HE PPDU on P160 by setting the first information to 1, and indicate the transmission of the PPDU of the corresponding version of 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 the transmission of the PPDU of the corresponding version of the existing special user information field on P160 and S160 by setting the first information to 0. Alternatively, the AP can indicate the transmission of a HE PPDU on P160 by setting the first information to 1, and indicate the transmission of PPDUs of different versions in two versions on P160 and S160 respectively by configuring the special user information field of EHT and the special user information field of UHR in the user information list field. Specifically, which version of the PPDU to transmit is indicated by the value set by the AP for the second information. By way of example, when the second information is 0, it indicates that P160 corresponds to EHT and S160 corresponds to UHR, and when the second information is 1, it indicates that P160 corresponds to UHR and S160 corresponds to EHT.

[0224] Example 4: The second information is a 2-bit information. For the specific meanings jointly indicated by the first information, the second information, and other configurations, see Table 8.

[0225] Table 8

[0226]

[0227] The difference between Table 8 and Table 6 is that when the second information is 0, a future configuration can be indicated through other configurations. For example, consider more versions of PPDUs after UHR, etc. This value can be jointly indicated in combination with more bits and certain fields such as whether there is a special user information field.

[0228] In S620, the AP sends a trigger frame to the STA. Correspondingly, the STA receives the trigger frame from the AP.

[0229] For the description of S620, refer to the description in S520 and will not be elaborated here.

[0230] In S630, the STA determines the type of the TB PPDU to be transmitted on P160 and / or S160 based on the first information and the second information.

[0231] For how the STA determines the type of the TB PPDU to be transmitted on P160 and / or S160, specifically refer to the relevant description in S610 on how the AP indicates the type of the TB PPDU to be transmitted on P160 and / or S160, and will not be elaborated here.

[0232] In one implementation, since the specific resources (RU or MRU) allocated to the STA are located at P160 and / or S160, in practice, the STA needs to jointly determine the type of the TB PPDU transmitted on P160 and / or S160 based on the first information, the second information (which may also include the information in the special user information field), and the information #A in the user information field corresponding to the STA.

[0233] Taking Table 5 as an example, if the STA parses the trigger frame to obtain the first information as 0, the second information as 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 does not need to pay attention to S160; for another 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 does not need to pay attention to P160.

[0234] In another implementation, the STA can jointly determine the User Info filed variant corresponding to the STA based on the first information carried in the common information field, the version corresponding to at least one special user information field and / or the uplink bandwidth, and the information A in the user information field corresponding to the STA. The STA can 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 implementation of the STA determining the type of the TB PPDU transmitted on P160 and / or S160 and the STA determining the user information field variant corresponding to the STA can be mutually replaceable, and no limitation is made.

[0235] Optionally, the method further includes:

[0236] S640, the STA sends the TB PPDU to the AP. Correspondingly, the AP receives the TB PPDU from the STA.

[0237] For the description of S640, refer to the description in S540, which will not be elaborated here.

[0238] The following combines Figure 7 to introduce another indication method. Figure 7 The difference between the method 700 shown and the method 600 is that two additional pieces of information are added. Among them, one piece of information indicates the type of the TB PPDU transmitted on P160, and the other piece of information indicates the type of the TB PPDU transmitted on S160. The method 700 will be introduced below.

[0239] Figure 7It is a schematic diagram of a communication method 700 proposed by an embodiment of the present application. The method 700 includes the following steps.

[0240] S710, the AP generates a trigger frame. The trigger frame includes a common information field, a second information, and a third information. The common information field includes a first information, where the first information and the second information jointly indicate one of the HE PPDU, EHT PPDU, and UHR PPDU transmitted on P160, and the third information indicates one of the EHT PPDU and UHR PPDU transmitted on S160.

[0241] Optionally, the first information is carried in the first field of the common information field. Exemplarily, the first information is a first value, indicating that the TB PPDU transmitted on P160 is a PPDU after the HE version, and the first information is a second value, indicating that the TB PPDU transmitted on P160 is a HE PPDU.

[0242] It should be understood that the present application does not make specific limitations on the name and length of the first field. Exemplarily, 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.

[0243] Optionally, the first information can also be carried in multiple fields of the common information field, that is, the first information is jointly indicated by multiple fields.

[0244] Optionally, the second information or the third information can be carried in one or more fields of the common information field, or the second information or the third information can also be carried in one or more fields of the user information field.

[0245] For ease of understanding, taking the first information, the second information, and the third information as 1-bit information, and the first value of the first information is 0 and the second value is 1 as an example, a table that an AP may refer to when indicating the type of the TB PPDU transmitted on P160 and / or S160 is exemplarily given. Specifically, see Table 9 and Table 10.

[0246] Table 9

[0247]

[0248] Table 10

[0249]

[0250]

[0251] Specifically, based on Table 9, the AP can indicate the transmission of a HE PPDU on P160 by setting the first information to 1 and the second information to 1. Alternatively, the AP indicates the transmission of an EHT PPDU on P160 by setting the second information to 0 and the second information to 0. Alternatively, the AP indicates the transmission of a UHR PPDU on P160 by setting the second information to 0 and the second information to 1.

[0252] It can be understood that when the first information is 1, it is already 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.

[0253] Specifically, based on Table 10, the AP can indicate the transmission of an EHT PPDU on S160 by setting the third information to 0. Alternatively, the AP indicates the transmission of a UHR PPDU on S160 by setting the third information to 1.

[0254] S720, the AP sends a trigger frame to the STA. Correspondingly, the STA receives the trigger frame from the AP.

[0255] For the description of S720, refer to the description in S520, which will not be elaborated here.

[0256] S730, the STA determines the type of the TB PPDU transmitted on P160 based on the first information and the second information, and / or determines the type of the TB PPDU transmitted on S160 based on the third information.

[0257] Regarding how the STA determines the type of the TB PPDU transmitted on P160 and / or S160, specifically refer to the relevant description in S710 about how the AP indicates the type of the TB PPDU transmitted on P160 and / or S160, which will not be elaborated here.

[0258] In one implementation, since the specific resources (RU or MRU) allocated to the STA are located on P160 and / or S160, therefore, in practice, the STA needs to jointly determine the type of the 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 the TB PPDU transmitted on S160 based on the third information and the information #A in the user information field corresponding to the STA.

[0259] Taking Table 9 and Table 10 as examples, if the information A carried in the user information field of the STA parsing trigger frame to obtain the STA indicates P160, and at the same time the first information 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 does not need to pay attention to the third information; for another example, if the information A carried in the user information field of the STA parsing trigger frame to obtain the STA indicates S160, and at the same time 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 does not need to pay attention to the first information and the second information.

[0260] In another implementation, the STA can jointly determine the User Info filed variant corresponding to the STA based on the first information carried in the common information field, the version corresponding to at least one special user information field and / or the uplink bandwidth and the information A in the user information field corresponding to the STA. The STA can 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 implementation of determining the type of the TB PPDU transmitted on P160 and / or S160 by the STA and determining the user information field variant corresponding to the STA can be mutually replaced, and no limitation is made.

[0261] Optionally, the method further includes:

[0262] S740, the STA sends a TB PPDU to the AP. Correspondingly, the AP receives the TB PPDU from the STA.

[0263] For the description of S740, refer to the description in S540, which will not be elaborated here.

[0264] It should be understood that the above Figure 5The method 500 shown can be regarded as a method for indicating the type of TB PPDU transmitted on P160 and / or S160, which is proposed on the basis of being compatible with the meaning of the existing HE / EHT P160 field. In practical applications, the first information can also be decoupled from the meaning of the existing HE / EHT P160 field, and the type of TB PPDU transmitted on P160 and / or S160 can be indicated based on the information related to the special user information field in the common 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, partial information in the special user information field (such as 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), the combination of certain information in multiple special user information fields (such as the combination of the corresponding uplink bandwidth), the order of multiple special user information, additional entries added to the special user information field (such as a column corresponding to P160 in Table 5), and the association relationship between the uplink bandwidth corresponding to the special user information field and the primary and secondary frequency domain positions).

[0265] For example, if it is decoupled from the meaning of the existing HE / EHT P160 field, the meanings corresponding to the first information being 0 and 1 in the above text can be swapped.

[0266] It should also be understood that Figure 7 The method shown is regarded as a method for indicating the type of TB PPDU transmitted on P160 and / or S160, which is proposed on the basis of being compatible with the meaning of the existing HE / EHT P160 field. In practical applications, the first information can also be decoupled from the meaning of the existing HE / EHT P160 field, and a joint indication can be made based on the first information in the common information field and one or more additional bit information.

[0267] For example, if it is decoupled from the meaning of the existing HE / EHT P160 field, Table 5 can be transformed into Table 11. It can be seen that in Table 11, the first information is decoupled from the meaning of the existing HE / EHT P160 field.

[0268] Table 11

[0269]

[0270] Optionally, this application can also make a combined indication of the method proposed in the embodiments of this application. For example, the above method 500 and method 700 are combined for indication, and this application does not make a limitation.

[0271] It should also be understood that the embodiments of the present application are described by taking the example that different types of TB PPDUs may be transmitted on P160 and S160. In practical applications, three or even more types of TB PPDUs may also be transmitted on P160 and S160. For example, it is supported to transmit three different types of TB PPDUs on P80, S80, and S160 respectively. The present application does not limit the transmission granularity of the PPDU. As long as it conforms to the scenario of transmitting different types of TB PPDUs in different frequency ranges, the method provided by the present application can be used to indicate the types of TB PPDUs transmitted in different frequency ranges. For example, based on the above method, it is also possible to transmit different types of TB PPDUs on the low-frequency 80 of P160, S160, and the high-frequency 80 of S160 respectively. Another example is that based on the above method, it is also possible to transmit different types of TB PPDUs on P40, S40, S80, the low-frequency 80 of P160, and the high-frequency 80 of S160 respectively. Examples are not listed one by one here.

[0272] The solution proposed in the present application can be applied to the scenario where A-PPDU exists, and can also be applied to the scenario where A-PPDU does not exist. For the scenario where A-PPDU does not exist, the indication of non-A-PPDU can be achieved by reducing the corresponding entries or combinations of the A-PPDU scenario. For example, the number of bits corresponding to the new information in the above table (such as Table 5) containing new bit information can be reduced to reduce the corresponding entries or combinations of the A-PPDU scenario in the above table. Or, the entries corresponding to the A-PPDU scenario in the above table (such as Table 2) that does not contain new bit information can be set to Reserved entries (for example, the descriptions corresponding to the second last row to the fifth last row in Table 2 are set to Reserved) to reduce the corresponding entries or combinations of the A-PPDU scenario. In addition, in the non-A-PPDU scenario, if there is no special user information field, it means that the transmitted non-A-PPDU is a HE PPDU. When a special user information field appears (which can be informed in the common information field or obtained by reading the special user information field), it is considered that the transmitted non-A-PPDU is the PPDU of the version corresponding to the special user information field. For example, there is a 2-bit bitmap in the common information field indicating EHT and UHR. 11 means that there is no corresponding special user information field, then both the common information field and the user information field correspond to HE; 10 means that the EHT special user information field exists, then both the common information field and the user information field correspond to EHT; 01 means that the UHR special user information field exists, then both the common information field and the user information field correspond to UHR. 0 and 1 are just examples, and the present application does not make restrictions.

[0273] Optionally, the above method can also be combined with fields such as the RU allocation field and the PS160 field in the user information field to jointly complete the indication. It can also be understood that some optional features in the embodiments of the present application can, in some scenarios, be independent of other features, and in some scenarios, can be combined with other features, without limitation.
