[0065] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0066] FIG. 1 is an example of a communication system architecture to which embodiments of the present application are applied.

[0067] As shown in FIG. 1, the communication system 100 can include an AP 110 and STAs 120 accessing a network through the AP 110. In some scenarios, the AP 110 can also be referred to as an AP STA, that is, in some sense, the AP 110 is also a kind of STA. In some scenarios, the STA 120 is also referred to as a non-AP STA. In some scenarios, the STA 120 can include an AP STA and a non-AP STA. The communication in the communication system 100 can include communication between the AP 110 and the STA 120, or communication between the STA 120 and the STA 120, or communication between the STA 120 and a peer STA, where the peer STA can refer to a peer device that communicates with the STA 120, for example, the peer STA can be an AP or a non-AP STA.

[0068] The AP 110 can be used as a bridge connecting a wired network and a wireless network, and mainly functions to connect various wireless network clients together and then access the wireless network to the Ethernet. The AP 110 can be a terminal device (such as a mobile phone) or a network device (such as a router) with a WiFi chip.

[0069] It should be noted that the role of the STA 120 in the communication system is not absolute, that is, the role of the STA 120 in the communication system can be switched between the AP and the STA. For example, in some scenarios, when a mobile phone is connected to a router, the mobile phone is a STA, and when the mobile phone is used as a hotspot for other mobile phones, the mobile phone plays the role of an AP.

[0070] In some embodiments, the AP 110 and the STA 120 can be devices applied in vehicle-to-everything (V2X), internet of things (IoT) nodes, sensors, etc. in the internet of things (IoT), smart cameras, smart remote controllers, smart water meters, smart electricity meters, etc. in a smart home, and sensors, etc. in a smart city.

[0071] In some embodiments, the AP 110 can be a device supporting the 802.11be standard. The AP can also be a device supporting multiple current and future WLAN standards of the 802.11 family, such as 802.11ax, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a. In some embodiments, the STA 120 can support the 802.11be standard. The STA can also support multiple current and future WLAN standards of the 802.11 family, such as 802.11ax, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a.

[0072] In some embodiments, the AP 110 and / or the STA 120 can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; can also be deployed on water (such as a ship); and can also be deployed in the air (such as on an airplane, a balloon, and a satellite, etc.).

[0073] In some embodiments, the STA 120 can be a mobile phone, a tablet, a computer with wireless transceiver, a virtual reality (VR) device, an augmented reality (AR) device, a wireless device in industrial control, a set-top box, a wireless device in self-driving, a vehicle-mounted communication device, a wireless device in remote medical treatment, a wireless device in a smart grid, a wireless device in transportation safety, a wireless device in a smart city, a wireless device in a smart home, a vehicle-mounted communication device, a wireless communication chip / application specific integrated circuit (ASIC) / system on chip (SoC), etc. supporting WLAN / WiFi technology.

[0074] Exemplarily, the STA 120 can also be a wearable device. The wearable device can also be referred to as a wearable smart device, which is a general term for devices that are designed and developed by applying wearable technology to daily wear, such as glasses, gloves, watches, clothes, shoes, and the like. The wearable device is a portable device that is directly worn on the body or integrated into the clothes or accessories of the user. The wearable device is not only a hardware device, but also has strong functions through software support and data interaction and cloud interaction. The general wearable smart device includes devices with full functions and large sizes, which can realize complete or partial functions without relying on a smart phone, such as a smart watch or smart glasses, and devices that focus on a certain application function and need to be used in cooperation with other devices, such as a smart phone, such as various smart wristbands and smart jewelry for monitoring vital signs.

[0075] It should be understood that FIG. 1 is only an example of the present application and should not be construed as a limitation of the present application. For example, FIG. 1 only exemplarily shows one AP and two STAs, and in some embodiments, the communication system 100 can include multiple APs and include other numbers of STAs, which are not limited in the embodiments of the present application.

[0076] It should be noted that FIG. 1, FIG. 2A, FIG. 2B only schematically show the system to which the embodiments of the present application are applied in the form of examples, and of course, the method shown in the embodiments of the present application can also be applied to other systems. In addition, the terms "system" and "network" are often used interchangeably in this paper. The term "and / or" in this paper is only to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone. In addition, the character " / " in this paper generally represents an "or" relationship between the associated objects. It should also be understood that the "indication" mentioned in the embodiments of the present application can be direct indication or indirect indication, and can also mean an associated relationship. For example, A indicates B, which can mean that B can be obtained through A; or it can mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; or it can mean that A and B have an associated relationship. It should also be understood that the "corresponding" mentioned in the embodiments of the present application can mean a direct or indirect corresponding relationship between the two, or it can mean an associated relationship between the two, or it can mean an indication and being indicated, configuration and being configured, etc. It should also be understood that the "predefined" or "predefined rule" mentioned in the embodiments of the present application can be realized by pre-saving the corresponding code, table or other means that can be used to indicate related information in the device (for example, including terminal equipment and network equipment), and the specific implementation manner of the present application is not limited. For example, the predefined can mean the definition in the protocol. It should also be understood that the "protocol" in the embodiments of the present application can mean a standard protocol in the communication field, which can include the LTE protocol, the NR protocol and the related protocol applied to the future communication system, and the present application is not limited thereto.

[0077] In order to facilitate the understanding of the technical solutions of the embodiments of the present application, the related technologies of the embodiments of the present application are described as follows, and the following related technologies can be combined with the technical solutions of the embodiments of the present application in any way, which all belong to the protection scope of the embodiments of the present application.

[0078] In the related technologies, the co-hosted BSSID set and the multiple BSSID set are defined.

[0079] A co-hosted BSSID set is a set of access points (APs) that all use a common operating class, channel, receive antenna connector, and transmit antenna connector, each AP using a beacon or probe response frame to publish information for its BSSID.

[0080] A multiple BSSID set is a set of access points (APs) such that all APs use a common operating class, channel, receive antenna connector, and transmit antenna connector, and use a beacon or probe response frame transmitted by an AP corresponding to a transmitted BSSID to publish information for multiple BSSIDs.

[0081] The multiple BSSID set has the following characteristics:

[0082] All members of the set use a common operating class, channel, channel access function, receive antenna connector, and transmit antenna connector;

[0083] The size of the set can be up to 2 n For a selected value of n, if dotllmultibssldemented is true, then 1 < n < 8, and if dotllmultibssldemented (if present) is false, then 1 < n < 46, where dotllRMMeasurementPilotActivated is non-zero;

[0084] All BSSIDs (i.e., MAC addresses) in the multiple BSSID set are assigned in such a way that they cannot be MAC addresses of STAs using a different operating class, channel, receive antenna connector, or transmit antenna connector.

[0085] In an example, the APs within the BSSs for BSSIDs 16, 17, and 27 share the same operating class, channel, receive antenna connector, and transmit antenna connector, and the range of MAC addresses 16-31 (inclusive) is not assigned to other STAs using a different receive antenna connector or transmit antenna connector, then BSSIDs 16, 17, and 27 belong to a multiple BSSID set. This set is described with n = 4 (2 n = 16), and the range of BSSIDs is between 16-31. For example, this set cannot be described with n = 8, because there is at least one BSSID in the range 0-255 that can be used as a BSSID by an AP that does not share the same operating class, channel, receive antenna connector, and transmit antenna connector.

[0086] Coordinated Spatial Reuse (CSR)

[0087] CSR is applied in multi-AP operation scenarios. As shown in FIG. 3, by adopting CSR for transmission opportunity (TXOP) sharing, AP1 and AP2 can simultaneously communicate with their associated stations respectively by using different transmission powers in the channel bandwidth and time range corresponding to the shared TXOP.

[0088] Before CSR transmission between two APs, the APs participating in CSR need to negotiate and establish CSR, and the CSR setting process is performed by exchanging request / response frames to negotiate parameters involved in CSR. If a multi-AP coordinated transmission (including coordinated spatial reuse CSR) protocol has been established between two APs, one AP can send a CSR trigger frame to the other AP to initiate CSR transmission in its TXOP, the AP sending the CSR trigger frame is the sharing AP (Sharing AP), and the AP receiving the CSR trigger frame is the shared AP (Shared AP); in the shared TXOP time range, AP1 and AP2 can simultaneously communicate with their associated non-AP stations respectively.

[0089] In CSR transmission, the APs participating in CSR need to know the path loss between the scheduled STA and the interfering AP. Therefore, path loss measurement needs to be performed before CSR transmission. As shown in FIG. 4, AP1 needs to know the path loss between AP2 (interfering AP) and its non-AP STA; if AP1 is the sharing AP, AP1 needs to use the path loss to control the power of AP2, and at the same time, AP1 needs to use the path loss to estimate the SINR at the non-AP STA. The Beacon Request / Response and Null Data Packet (NDP) measurement mechanisms can be used for path loss measurement.

[0090] The multi-AP coordinated operation, i.e., multi-AP cooperation (such as coordinated spatial reuse, coordinated TDMA (C-TDMA), coordinated beamforming (CBF), etc.), involves cross-BSS control frame interaction issues.

[0091] In the related art, the following contents are discussed for multi-AP cooperation:

[0092] Content 1, a MAC protocol signaling mechanism for coordinated beamforming, in which two control frame exchanges are required to initiate a coordinated beamforming operation, and there is a problem of how to link the second control frame exchange if the first control frame exchange fails, but the establishment of a multi-AP coordination set is not involved, and the signaling overhead is large.

[0093] Content 2, a unified framework for MAP coordination configuration, proposes a multi-AP coordination link pair establishment method, does not involve the specific establishment process and signaling interaction of the multi-AP coordination set, and there is a problem of excessive management frame exchange in the multi-AP coordination link pair establishment or maintenance process; at the same time, it also does not involve the problem of initiating multi-AP cooperation through control frames.

[0094] Content 3, an AP in a co-hosted or multi-BSSID set negotiates with another AP in a co-hosted or multi-BSSID set to establish multi-AP operation, but does not involve the establishment of a multi-AP coordination set.

[0095] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined with the technical solutions of the embodiments of the present application as optional schemes, which all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0096] The wireless communication method provided by the embodiments of the present application is applied to a first AP, as shown in FIG. 5, and includes the following steps.

[0097] S501, the first AP sends a first frame, the first frame is used to publish one or more first information, the first information is the information of a corresponding multi-AP coordination set, and the first AP is a coordinated AP and / or a coordinated AP of the multi-AP coordination set.

[0098] The wireless communication method provided by the embodiments of the present application is applied to a first device, as shown in FIG. 6, and includes the following steps.

[0099] S601, the first device receives a first frame, the first frame is used to publish one or more first information, and the first information is the information of a corresponding multi-AP coordination set.

[0100] Next, the wireless communication method shown in FIG. 5 or FIG. 6 is described.

[0101] The first AP is an AP that joins one or more multiple-AP coordination sets, wherein for one multiple-AP coordination set, the first AP can be a coordinating AP and / or a coordinated AP of the multiple-AP coordination set. It can be understood that the role of the first AP in the multiple-AP coordination set includes a coordinating AP and / or a coordinated AP. At a certain time, the role of the first AP in the multiple-AP coordination set is a coordinating AP or a coordinated AP. Wherein, the role of the first AP in different multiple-AP coordination sets is the same or different.

[0102] It can be understood that the coordinating AP shares the obtained transmission opportunity to the coordinated AP in the case of obtaining the transmission opportunity, and the coordinating AP can be alternatively described as a sharing AP, and the coordinated AP can be alternatively described as a shared AP.

[0103] In the embodiments of the present application, the multiple-AP coordination set can be alternatively described as a coordinated multiple AP set or a coordinated multiple BSSID set.

[0104] The first AP broadcasts a first frame, and the first frame carries first information of each AP coordination set in one or more multiple-AP coordination sets. For one first information, it is the information of one multiple-AP coordination set. It can be understood that the first information includes the multiple-AP cooperation parameter and / or the multiple-AP cooperation capability indication of the corresponding multiple-AP coordination set.

[0105] In the case that the first AP broadcasts the first frame, the first device receives the first frame. Wherein, the first device is one of one or more devices that receive the first frame, and the first device can be an AP or a Non-AP STA. If the first device is an AP, the first device can be referred to as a second AP, and the second AP and the first AP belong to different BSSs; if the first device is a Non-AP STA, the first device can be referred to as a first Non-AP STA, wherein the first Non-AP STA is a Non-AP STA associated with the first AP.

[0106] In an example, as shown in FIG. 7, the AP 701 broadcasts a first frame, and the AP 702-1, the AP 702-2, the Non-AP STA 703, and the Non-AP STA 704 receive the first frame respectively. Wherein, any device in the AP 702-1, the AP 702-2, the Non-AP STA 703, and the Non-AP STA 704 can be understood as the first device.

[0107] In the embodiments of the present application, the first AP publishes information of one or more multi-AP coordination sets, and for a multi-AP coordination set, the first AP is a coordinating AP and / or a coordinated AP of the multi-AP coordination set. The publication of the information of the first AP enables a station receiving the information sent by the first AP to timely learn the establishment of the multi-AP coordination set, and thus to timely join the multi-AP coordination set, implement multi-AP cooperation, and improve resource utilization.

[0108] In some embodiments, the establishment of the multi-AP coordination set can adopt one or more of the following manners:

[0109] Manner 1: Two or more APs jointly establish the multi-AP coordination set through mutual negotiation, wherein an AP participating in the negotiation and successfully negotiating becomes a member device of the multi-AP coordination set;

[0110] Manner 2: An AP first establishes the multi-AP coordination set with itself as a coordinating AP and / or a coordinated AP, and the AP becomes a member device of the multi-AP coordination set;

[0111] Manner 3: If a device (an AP or a non-AP STA) intends to join an established multi-AP coordination set as a member device, the device negotiates with one or more coordinating APs already existing in the multi-AP coordination set, and only when the one or more coordinating APs accept the device as a member device, the device successfully joins the multi-AP coordination set and becomes a member device.

[0112] In some embodiments, the multi-AP coordination set has one or more of the following features:

[0113] Feature 1: Different APs in the multi-AP coordination set use the same or overlapping operating channels;

[0114] Feature 2: The APs in the multi-AP coordination set are distributed at different geographical locations, or part of the APs in the multi-AP coordination set are distributed at different geographical locations;

[0115] Feature 3: The member devices of the multi-AP coordination set include one or more coordinating APs and / or one or more coordinated APs;

[0116] Feature 4: The member APs of the multi-AP coordination set specify a BSSID for multi-AP cooperation;

[0117] Feature 5: The member devices of the multi-AP coordination set include one or more non-access stations (Non-AP STAs), and the Non-AP STAs are associated with a coordinated AP or a coordinating AP in the multi-AP coordination set;

[0118] Feature 6, the coordinating AP allocates and maintains the AP identifier of the coordinated AP, and / or allocates and maintains the station identifier (STA ID) of the member Non-AP STA associated with the coordinated AP, for indicating the coordinated AP and / or the member Non-AP STA associated with the coordinated AP in a trigger frame when the coordinating AP initiates the multi-AP cooperation.

[0119] Feature 7, the coordinated AP maintains the MAC address of the coordinating AP and / or the designated BSSID used by the coordinating AP for the multi-AP cooperation, and the AP identifier (AP ID) allocated to the coordinated AP by the coordinating AP.

[0120] Feature 8, the member Non-AP STA maintains the MAC address of the coordinating AP and / or the designated BSSID used by the coordinating AP for the multi-AP cooperation, and the station identifier allocated to the member Non-AP STA by the coordinating AP.

[0121] Feature 9, if the member AP of the multi-AP coordination set is both a coordinating AP and a coordinated AP, whether the member AP is a coordinating AP depends on whether the member AP competes for a TXOP to initiate the multi-AP cooperation.

[0122] Feature 10, the multi-AP cooperation of the member devices in the multi-AP coordination set is initiated by the coordinating AP of the multi-AP coordination set.

[0123] In the embodiments of the present application, the multi-AP coordination set includes a plurality of member devices, wherein the member devices can be APs or Non-AP STAs. The multi-AP cooperation based on the multi-AP coordination set is the transmission of PPDU between each member device of the multi-AP coordination set and the associated AP or Non-AP STA.

[0124] For feature 1, when different APs in the same multi-AP coordination set perform the transmission of PPDU with the respective associated Non-AP STAs, i.e., perform the multi-AP cooperation based on the multi-AP coordination set, the operating channels used are the same or overlap.

[0125] In the embodiments of the present application, the operating channels used by different APs are the same in the time domain, frequency domain or spatial domain.

[0126] For feature 2, one multi-AP coordination set includes a plurality of APs distributed in different geographical locations.

[0127] In the embodiments of the present application, the geographical locations of the APs in one multi-AP coordination set are all different, or the geographical locations of some APs are different and there are APs with the same address location.

[0128] In feature 3, the coordinating AP in the multi-AP coordination set can include a designated AP pre-agreed or set, or an AP that obtains a transmission opportunity. For a multi-AP coordination set, one or more coordinating APs can be included, and the APs included in the multi-AP coordination set, except for the coordinating APs, are APs in the multi-AP coordination set.

[0129] In embodiments of the present application, the coordinating AP initiates the multi-AP coordination operation, and the coordinated AP is triggered by other coordinating APs in the multi-AP coordination set to participate in the multi-AP coordination operation.

[0130] For feature 4, the member AP can be a coordinating AP and / or a coordinated AP.

[0131] In some embodiments, the coordinating AP of the multi-AP coordination set specifies a coordinating BSSID.

[0132] If the member AP is a coordinating AP, the BSSID indicated by the member AP for multi-AP cooperation can be referred to as a coordinating BSSID.

[0133] It can be understood that the coordinated AP can also specify a coordinating BSSID.

[0134] In some embodiments, the coordinating BSSID is a BSSID specified by an AP in the multi-AP coordination set as a coordinating AP for multi-AP cooperation based on the multi-AP coordination set, and / or an AP in the multi-AP coordination set as a coordinating AP sets the coordinating BSSID in a transmission address (TA) in a transmitted trigger frame for initiating multi-AP cooperation.

[0135] In some embodiments, the coordinating BSSID can be a MAC address of the coordinating AP, or a BSSID used by the coordinating AP for multi-AP cooperation based on the corresponding multi-AP coordination set.

[0136] For feature 5, the member devices of the multi-AP coordination set can also include a Non-AP STA, which is a Non-AP STA associated with a coordinating AP or a coordinated AP in the multi-AP coordination set.

[0137] In the case where the member devices of the multi-AP coordination set include a Non-AP STA, one or more Non-AP STAs included in the multi-AP coordination set can form a coordinated multi-STA set attached to the multi-AP coordination set.

[0138] In embodiments of the present application, the coordinated multi-STA set attached to the multi-AP coordination set participates in multi-AP cooperation of the multi-AP coordination set, and the set of STAs associated with the coordinating AP or the coordinated AP.

[0139] In embodiments of the present application, the multi-AP coordination can be referred to as multi-AP coordinated operation. In a case where the member devices of the multi-AP coordination set include Non-AP STAs, the participating members of the multi-AP coordination triggered by the trigger frame can include the Non-AP STAs, and in this case, the multi-AP coordination can be alternatively described as multi-site coordination, or multi-AP and / or multi-Non-AP STA coordination.

[0140] For feature 6, it can be understood that, in a case where the coordinated APs are triggered to participate in the multi-AP coordination based on the trigger frame, the coordinated APs are indicated using the AP identifiers of the coordinated APs by the coordinating AP. In a case where the Non-AP STAs associated with the coordinated APs are triggered to participate in the multi-AP coordination based on the trigger frame, the Non-AP STAs associated with the coordinated APs are indicated using the STA identifiers of the Non-AP STAs by the coordinating AP.

[0141] In embodiments of the present application, the AP identifier can be alternatively described as AP ID, and the STA identifier can be alternatively described as STA ID.

[0142] For feature 7, the information maintained by the coordinated APs is described.

[0143] For feature 8, the information maintained by the member Non-AP STAs is described.

[0144] The member Non-AP STAs are the Non-AP STAs included in the member devices of the multi-AP coordination set.

[0145] For feature 9, in a case where a member AP obtains a transmission opportunity and initiates the multi-AP coordination, the member AP can assume the role of the coordinating AP.

[0146] For feature 10, for the multi-AP coordination set, the multi-AP coordination based on the multi-AP coordination set is initiated by the coordinating AP of the multi-AP coordination set based on the trigger frame.

[0147] In some embodiments, the multi-AP coordination of the member devices in the multi-AP coordination set is initiated by the coordinating AP of the multi-AP coordination set after obtaining a transmission opportunity TXOP or a shared part of the TXOP period.

[0148] In some embodiments, the multi-AP coordination supports one or more of the following schemes:

[0149] Coordinated Spatial Reuse (C-SR), Coordinated Time Division Multiple Access (C-TDMA), Coordinated Beamforming (C-BF), Coordinated Restricted Target Wake Times (C-RTWT).

[0150] In the embodiments of the present application, when the first frame carries multiple first information, the schemes supported by the multiple-AP coordination set corresponding to different first information are the same or different, and the schemes used by the multiple-AP coordination set corresponding to different first information are the same or different.

[0151] In some embodiments, the first frame comprises a management frame.

[0152] In some embodiments, the management frame comprises a beacon frame or a probe response frame.

[0153] In some embodiments, for the first AP, the method further comprises:

[0154] The first AP receives a second frame, and the second frame is used to indicate that the first device requests to establish or join a first multiple-AP coordination set corresponding to one of the one or more first information.

[0155] Correspondingly, in some embodiments, for the first device, the method further comprises:

[0156] The first device sends a second frame, and the second frame is used to indicate that the first device requests to establish or join a first multiple-AP coordination set corresponding to one of the one or more first information, and a coordination AP of the first multiple-AP coordination set is the first AP.

[0157] Understandably, in the case of establishing the first multiple-AP coordination set, the second frame is used to request to establish the first multiple-AP coordination set. In the case of joining the established first multiple-AP coordination set, the second frame or the first frame can be sent first, and at this time, the second frame is used to request to join the first multiple-AP coordination set.

[0158] In the embodiments of the present application, the transmission of the second frame can be prior to the transmission of the first frame, or can be subsequent to the transmission of the first frame.

[0159] For example, as shown in FIG. 8A, the first device sends the second frame to the first AP to request to join the first multi-AP coordination set in the case that the first device receives the first frame sent by the first AP. The first frame publishes information of one or more multi-AP coordination sets, and the first multi-AP coordination set is one of the one or more multi-AP coordination sets.

[0160] In FIG. 8A, the first device sends the second frame to the first AP in the case that the first device receives the first frame and determines to need to join the first multi-AP coordination set.

[0161] For example, the second device sends the second frame to the first AP to request to establish or join the first multi-AP coordination set, and the second frame is used to request to establish or join the first multi-AP coordination set. After the first AP establishes or joins the first multi-AP coordination set, the first AP sends the first frame to publish information of the established or updated first multi-AP coordination set.

[0162] In the embodiments of the present application, the second frame can be defined as a multi-AP coordination set join request frame or a multi-AP coordination set establishment request frame.

[0163] In some embodiments, the second frame includes first information corresponding to the first multi-AP coordination set and / or first configuration information, and the first configuration information is configuration information of the first device requesting to join the first multi-AP coordination set.

[0164] The first information corresponding to the first multi-AP coordination set carried in the second frame is used to indicate the first multi-AP coordination set that the first device requests to establish or join, that is, which multi-AP coordination set is established or joined.

[0165] The first configuration information carried in the second frame is used to indicate which device requests to join the first multi-AP coordination set.

[0166] In the embodiments of the present application, the first device can be a second AP or a first Non-AP STA associated with the first AP.

[0167] In some embodiments, in the case that a third frame indicating that the first device is not allowed to join the first multi-AP coordination set is not received within a first time length after the second frame is sent, the first device can be allowed to join the first multi-AP coordination set by default.

[0168] In some embodiments, for the first AP, the method further includes:

[0169] The first AP sends a third frame to the first device, and the third frame is used to indicate whether the first device is allowed to establish or join the first multi-AP coordination set.

[0170] Correspondingly, in some embodiments, for the first device, the method further comprises:

[0171] The first device receives a third frame sent by the first AP, the third frame being used to indicate whether the first device is allowed to establish or join the first multi-AP coordination set.

[0172] As shown in FIG. 9A, in the case that the first AP receives the second frame sent by the first device, the first AP sends a third frame to the first device to respond to whether the first device is allowed to establish or join the first multi-AP coordination set, and the first device determines whether to establish or join the first multi-AP coordination set based on the received third frame.

[0173] It can be understood that the third frame is used to respond to the second frame.

[0174] In the embodiments of the present application, the third frame can be defined as a multi-AP coordination set request join response frame or a multi-AP coordination set request establishment response frame.

[0175] In the embodiments of the present application, in the case that the first device receives the first frame and determines that it needs to join the first multi-AP coordination set, the first device sends a second frame to the first AP, and the first device responds to the third frame. At this time, the frame exchange process is as shown in FIG. 9A.

[0176] In the embodiments of the present application, the frame exchange process can also be as shown in FIG. 9B. In the case that the first device determines that it needs to establish or join the first multi-AP coordination set, the first device sends a second frame to the first AP, and the first device responds to the second frame. In the case that the third frame indicates that the first multi-AP coordination set is established or the first device joins the first AP coordination set, the first device sends a first frame. At this time, the first frame is used to publish the information of the established or updated first AP coordination set.

[0177] In the embodiments of the present application, for the frame exchange process shown in FIG. 9A or FIG. 9B, after the first device joins the first AP coordination set, the first device can broadcast a first frame to publish the information of the established or updated first AP coordination set.

[0178] In some embodiments, the third frame comprises one or more of the following:

[0179] First indication information, the first indication information being used to indicate whether the first device is allowed to join the first multi-AP coordination set;

[0180] First information, the first information being the information of the currently established or updated multi-AP coordination set;

[0181] First identification, the first identification indicating the identification assigned by the first AP to the first device, and being used to indicate the first device in a trigger frame when initiating multi-AP cooperation.

[0182] The first indication information can be understood as a status code, used to indicate whether the first device is allowed to establish or join the first multi-AP coordination set. The first indication information indicates whether the first device is allowed to establish or join the first multi-AP coordination set based on different values.

[0183] In an example, the length of the status code is 1 byte, the value of the status code is 0, indicating that the first device is allowed to join the first multi-AP coordination set; the value of the status code is 0, indicating that the first device is not allowed or refused to join the first multi-AP coordination set.

[0184] When the first indication information indicates that the first multi-AP coordination set is allowed to be established, the second frame includes first information used to indicate the established or updated first multi-AP coordination set.

[0185] When the first indication information allows the first device to join the first multi-AP coordination set, the coordinating AP allocates or maintains a first identifier for the first device, and the third frame carries the first identifier, used to indicate the first device in a trigger frame when initiating multi-AP cooperation.

[0186] In the embodiments of the present application, the transmission of the first frame can be prior to the transmission of the second frame (such as shown in FIG. 9A), or can be subsequent to the transmission of the second frame (such as shown in FIG. 9B). For convenience of description, in the following description, the transmission of the first frame is limited to the transmission of the second frame as an example for description.

[0187] In some embodiments, the first AP is a coordinating AP of the first multi-AP coordination set, and the first device is a second AP.

[0188] At this time, the second frame is used for the second AP to request to join the first multi-AP coordination set with the first AP as the coordinating AP, or is used for the second AP to request to establish the first multi-AP coordination set.

[0189] In an example, the first AP is AP1, and the second AP is AP2. As shown in FIG. 10, AP1 sends the first frame, AP2 sends the second frame to AP1 in the case of receiving the first frame, and AP1 receives the second frame and responds to AP2 with the third frame.

[0190] In some embodiments, the first AP is a coordinated AP of the first multi-AP coordination set, and the first device is a first Non-AP STA, which is a Non-AP STA associated with the first AP.

[0191] At this time, the second frame is used for the first Non-AP STA to request to join the first multi-AP coordination set with the first AP as the coordinated AP, or is used for the first Non-AP STA to request to establish the first multi-AP coordination set.

[0192] In an example, the first AP is AP1, and the first Non-AP STA is Non-AP STA1 associated with AP1, as shown in FIG. 11: AP1 sends a first frame, Non-AP STA1 sends a second frame to AP1 upon receiving the first frame, and AP1 sends a third frame to Non-AP STA1 in response to receiving the second frame.

[0193] In the embodiments of the present application, for an AP, the AP can act as a second AP, and become a coordinated AP of a multi-AP coordination set through frame interaction with a coordinating AP; after joining the multi-AP coordination set, the AP can send a first frame as a coordinated AP, thereby publishing the multi-AP coordination set that the AP has joined. Alternatively, the AP can act as a coordinated AP, and become a member device of the multi-AP coordination set through second frame and third frame interaction between the AP and a Non-AP STA associated with the AP.

[0194] In some embodiments, after the first AP sends the third frame to the first device, the method further includes:

[0195] The first AP sends a fourth frame to a third AP, the fourth frame being used to indicate that the first Non-AP STA has joined the first multi-AP coordination set, and the third AP being a coordinating AP of the first multi-AP coordination set.

[0197] If the first AP is a coordinated AP, and the first AP determines to allow the first Non-AP STA to join the first multi-AP coordination set, the first AP sends a fourth frame to a coordinating AP of the first multi-AP coordination set, the fourth frame being used to notify the first Non-AP STA to join the first multi-AP coordination set.

[0198] In an example, the first AP is AP1, the first Non-AP STA is Non-AP STA1 associated with AP1, and the third AP is AP2, as shown in FIG. 12 based on FIG. 11: AP1 sends a third frame to Non-AP STA1, and then sends a fourth frame to AP2.

[0199] In the embodiments of the present application, the fourth frame can be defined as a multi-AP coordination set joining notification frame or a multi-AP coordination set parameter update notification frame.

[0200] In some embodiments, the fourth frame includes first information corresponding to the first multi-AP coordination set;

[0201] The first information corresponding to the first multi-AP coordination set includes second configuration information, and the second configuration information is configuration information of the first Non-AP STA that has joined the first multi-AP coordination set.

[0202] The first information in the fourth frame is used to notify parameter update in the first multi-AP coordination set. It can be understood that the second configuration information included in the first information is used to notify configuration information of the first Non-AP STA that is added to the first multi-AP coordination set.

[0203] In some embodiments, the third AP receives the fourth frame and sends confirmation information in response to the fourth frame.

[0204] In the embodiments of the present application, whether the Non-AP STA associated with the coordinated AP of the multi-AP coordination set joins the multi-AP coordination set can be determined by the coordinated AP, thereby strengthening the capability of the coordinated AP in the multi-AP coordination set and improving the flexibility of the scheme.

[0206] The first AP sends a fourth frame to a third AP, and the fourth frame is used to indicate that the first Non-AP STA requests to join the first multi-AP coordination set, and the third AP is a coordinated AP of the first multi-AP coordination set.

[0207] The first AP receives the second frame and sends a fourth frame to a third AP, and the fourth frame is used to indicate that the Non-AP STA associated with the first AP requests to join the first multi-AP coordination set in which the third AP is a coordinated AP.

[0208] The fourth frame can be defined as a multi-AP coordination set parameter update request frame or a multi-AP coordination set STA join request frame.

[0209] In some embodiments, the fourth frame includes one or more of the following: first information corresponding to the first multi-AP coordination set and / or third configuration information, and the third configuration information is configuration information of the first Non-AP STA that requests to join the first multi-AP coordination set.

[0210] The first information corresponding to the first multi-AP coordination set carried in the fourth frame is used to indicate the first multi-AP coordination set to which the first Non-AP STA requests to join, that is, which multi-AP coordination set to join.

[0211] The third configuration information carried in the fourth frame is used to indicate which device requests to join the first multi-AP coordination set.

[0212] In some embodiments, the method further includes:

[0214] The first AP sends a fourth frame to the third AP, and the third AP sends a fifth frame to the first AP after receiving the fourth frame, and the fifth frame is used to indicate whether the first Non-AP STA is allowed to join the first multi-AP coordination set.

[0215] The fifth frame can be defined as a multi-AP coordination set parameter update response frame or a multi-AP coordination set STA join response frame.

[0216] In an example, the first AP is AP1, the first Non-AP STA is Non-AP STA1 associated with AP1, and the third AP is AP2. Based on FIG. 11, as shown in FIG. 13, AP1 receives the second frame sent by Non-AP STA1, sends a fourth frame to AP2, AP2 receives the fourth frame and sends a fifth frame to AP1, and AP1 receives the fifth frame and then sends a third frame to Non-AP STA1.

The description of the status code can be referred to the description of the status code involved in the first indication information, which will not be repeated here. The second identification is an identification allocated or maintained by the coordination AP for the first device for indicating the first Non-AP STA in a trigger frame when initiating multi-AP cooperation in the case that the first Non-AP STA is allowed to join the first multi-AP coordination set.

[0221] In the case that the first device is the first Non-AP STA, the first identification and the second identification are the same information.

[0222] In some embodiments, the third frame is the forwarded fifth frame.

[0223] In the case that the first AP receives the fifth frame, the third frame is generated based on the information carried in the fifth frame, and the third frame is sent to the first Non-AP STA to realize forwarding of the third frame.

For the first information corresponding to different multi-AP coordination sets, different information can be included. For the first frame, the second frame and the fourth frame, the information included in the first information corresponding to the first multi-AP coordination set carried by each frame can be the same or different.

[0235] For the information 1, it can be defined as an identifier of the multi-AP coordination set.

[0236] In an example, the length of the information 1 can be 1 byte.

[0237] For the information 2, it can be defined as a coordination BSSID.

[0238] The understanding of the information 2 can refer to the description of the coordination BSSID in the feature 6 of the multi-AP coordination set, which is not repeated here.

[0239] The information 1 and / or the information 2 can indicate that the first information corresponds to a multi-AP coordination set.

[0240] For the information 3, a MAC address of a coordinating AP can be defined, which is a MAC address of a coordinating AP of the multi-AP coordination set corresponding to the first information.

[0243] The information 4 can be used to indicate whether the station sending the first information is a coordinating AP or a sharing AP in the multi-AP coordination set corresponding to the first information. In an example, the information 4 can have a length of 1 bit, and when the value of the information 4 is 1, it indicates that the station sending the first information is a coordinating AP or a sharing AP in the multi-AP coordination set corresponding to the first information, otherwise, it is set to 0.

[0244] In the embodiments of the present application, the station can be an AP or a Non-AP STA.

[0251] The information 7 is used to indicate whether the multi-AP coordination set corresponding to the first information currently still allows a new station, i.e., a member device, to join.

[0252] In an example, the length of the information 7 can be 1 bit, and when the value of the information 7 is 1, it indicates that the multi-AP coordination set corresponding to the first information is currently full, i.e., no new member device is allowed to join, otherwise it is set to 0.

[0253] The information 8 can be defined as whether to support the non-AP station triggering information across BSSs.

[0254] The information 8 is used to indicate whether the multi-AP coordination set corresponding to the first information supports the coordination AP directly triggering the associated non-AP station of the member AP to participate in the multi-AP cooperation.

[0259] In an embodiment of the present application, the ninth indication information can be defined as the current member AP quantity information, which is used to indicate the current member AP quantity, i.e., the first quantity. The first quantity can be 1 or an integer greater than 1.

[0260] The ninth indication information can be an 8-bit integer data.

[0261] The member information of each of the first quantity of member APs included in the multi-AP coordination set can be understood as a member AP information list, which includes one or more member information in the list, and different member information is the member information of different member devices in the multi-AP coordination set.

[0262] In some embodiments, the member information includes one or more of the following:

[0263] The MAC address of the member AP;

[0264] The BSSID of the member AP;

[0266] The BSSID of the member AP can be understood as the BSSID of the member AP used for multi-AP cooperation based on the multi-AP coordination set.

[0267] The length of the BSSID of the member AP can be 6 bytes.

[0268] In embodiments of the present application, for a coordinating AP, the BSSID is the BSSID of the BSS corresponding to the coordinating AP (i.e., the coordinating AP) or the sharing AP (i.e., the sharing AP), or the BSSID set in the TA for the coordinating AP to transmit the trigger frame for initiating the multi-AP cooperation (wherein the multi-AP cooperation is based on the multi-AP coordination set).

[0269] The role of the member AP in the multi-AP coordination set can include the following: coordinating AP, coordinated AP, and both coordinating AP and coordinated AP. Optionally, whether an AP is a coordinating AP depends on whether the AP competes for a TXOP to initiate a multi-AP coordination operation: when the AP competes for a TXOP to initiate a multi-AP coordination operation, the AP is a coordinating AP; when the AP is triggered by another coordinating AP in the multi-AP coordination set to perform a multi-AP coordination operation, the AP is a coordinated AP.

[0270] In an example, the tenth indication information can be indicated by 2 bits. When the value is 0, it indicates that the member AP is a coordinating AP; when the value is 1, it indicates that the member AP is a coordinated AP; and when the value is 2, it indicates that the member AP can be both a coordinating AP and a coordinated AP.

[0271] In some embodiments, the first information further includes one or more of the following:

[0275] For the configuration information of the coordinated AP, when the first information is contained in the first frame, the second frame sent by the first Non-AP STA, or the fourth frame, the configuration information of the coordinated AP is the configuration information of the coordinated AP which has joined the multi-AP coordination set; when the first information is contained in the second frame sent by the second AP, the configuration information of the coordinated AP is the configuration information of the AP which requests to join the multi-AP coordination set, that is, the configuration information of the AP which requests to be a coordinated AP of the multi-AP coordination set.

[0276] In the embodiments of the present application, when the first information includes the ninth indication information and the member information of each member AP, the fourth configuration information is the configuration information of the member AP of the multi-AP coordination set.

[0277] For the configuration information of the member AP, when the first information is carried in the first frame, it is the configuration information of the AP (or BSSID) which has joined the multi-AP coordination set; when the first information is carried in the second frame, it is the configuration information of the member AP which requests to join.

[0278] For the fifth configuration information, when the first information is contained in the fourth frame sent after the first frame, the second frame or the third frame, it is the configuration information of the Non-AP STA which has joined the multi-AP coordination set and participates in the multi-AP cooperation of the multi-AP coordination set; when the first information is contained in the fourth frame sent before the third frame, it is the configuration information of the Non-AP STA which requests to join the multi-AP coordination set, that is, the configuration information of the Non-AP STA which requests to participate in the multi-AP cooperation of the multi-AP coordination set.

[0279] In the embodiments of the present application, if the multi-AP coordination set includes one coordinated AP, the corresponding first information can include the fourth configuration information, and does not include the ninth indication information and the member information of each member AP in the first number of member APs included in the multi-AP coordination set. If the multi-AP coordination set includes one or more coordinated APs, the corresponding first information can include the ninth indication information and the member information of each member AP in the first number of member APs included in the multi-AP coordination set.

[0280] In the embodiments of the present application, for other frames except the second frame sent by the second AP, the fifth configuration information is optional.

[0281] In the embodiments of the present application, for other frames except the fourth frame sent before the third frame, the sixth configuration information is optional.

[0403] Next, the RA field in the sixth frame is described.

[0404] In some embodiments, the sixth frame includes a user information field, and a receiving address in the sixth frame is a bearing address of the user information field.

[0405] In the embodiments of the present application, the sixth frame includes a user information field, which indicates that the sixth frame is used to initiate multi-AP cooperation with one second device, at this time, the receiving end of the sixth frame is the one second device, and the address of the RA is the address of the user information field included in the sixth frame.

[0417] In some embodiments, the member device of the second multi-AP coordination set corresponds to multiple BSSs, and the sending address of the sixth frame is the coordination BSSID of the coordination AP of the multi-AP coordination set.

[0418] In the embodiments of the present application, if the sixth frame is sent to the second device belonging to a single BSS, the TA field is the address of the second device sending the trigger frame. If the sixth frame is sent to the second device from at least two different BSSs in the multi-AP (or BSSID) coordination set, the TA field is the coordination BSSID of the coordination AP of the multi-AP (or BSSID) coordination set.

[0419] In the embodiments of the present application, the sixth frame can further include one or more of the following fields: intermediate FCS field, padding field, FCS field, etc.

[0420] The Intermediate FCS field contains a 32-bit CRC, where the Intermediate FCS field value is computed over all fields in the MAC header and frame body up to the Intermediate FCS field. The Intermediate FCS field is used by the receiving STA to perform early validation of the information in the MAC header and frame body up to the Intermediate FCS field.

[0421] A Padding field is optionally present in a trigger frame to extend the frame length to give the receiving STA sufficient time to prepare a response to be sent SIFS after the frame is received. The length of the Padding field, if present, is at least two octets and is set to all ones. If a padding field is present in a trigger frame, its length is computed as described in the "Padding for Trigger Frames" table.

[0422] The FCS field contains a 32-bit CRC. The FCS field value is computed over all fields in the MAC header and frame body.

[0423] The wireless communication method provided by the embodiments of the present application reduces the processing overhead of the station receiving the cross-BSS control frame by restricting the cross-BSS control frame related fields (such as the TA address and the AID 12 / AP ID of the user information field).

[0424] The wireless communication method provided by the embodiments of the present application is further described below.

[0425] A multi-AP coordination set is a set of access points, so that all APs in the set use a common or overlapping operating channel, and can be distributed in different or same geographical locations, wherein the APs participate in multi-AP cooperative operation (such as coordinated spatial reuse C-SR, coordinated TDMA (C-TDMA), coordinated beamforming, etc.) as a coordinating AP (or a shared AP) or as a coordinated AP (or a shared AP). Each AP uses a beacon or probe response frame to publish information for its BSSID; optionally, the coordinating AP can communicate with the coordinated AP. In particular, the multi-AP coordination set can be a set of Non-collocated AP (BSSID) sets, which is a set of APs in different geographical locations; optionally, the multi-AP coordination set can also be a set of APs in the same geographical location. In particular, in some embodiments, for a specific multi-AP coordination set, only the coordinating AP of the multi-AP coordination set is allowed to initiate multi-AP cooperation based on the multi-AP coordination set by sending a cross-BSS trigger frame.

[0426] An AP, if acting as a coordinating AP (or sharing AP), can manage and maintain this coordinated multiple BSSID set, where the AP can include a coordinated multiple BSSID element in the management frames (beacon frames or probe response frames) it transmits, the BSSID of the AP acting as the coordinating AP is referred to as the coordinating BSSID for this coordinated multiple BSSID set.

[0427] A coordinating AP (such as AP1) can publish its multi-AP coordination operation parameters and information and / or multi-AP coordination operation capability indication as a coordinating AP through a management frame such as a beacon or probe response frame. AP2, upon receiving the beacon frame from AP1, can request to join the multi-AP coordination set of AP1 acting as the coordinating AP by sending a multi-AP coordination set join (or setup) request frame to AP1. AP1 can reject or accept the multi-AP coordination set join request from AP2 by replying with a multi-AP coordination set join (or setup) response frame. If AP2 joins the multi-AP coordination set of AP1 acting as the coordinating AP, it can publish the joined multi-AP coordination set in the beacon frames it publishes.

[0428] The multi-AP coordination trigger frame as a control frame for cross-BSS operation is used for a coordinating AP (or sharing AP) to initiate multi-AP coordinated transmission, where the coordinating AP allocates resources to one or more BSSes of coordinated APs and / or non-AP STAs associated with the coordinating AP or coordinated APs to transmit non-TB PPDUs or TB PPDUs; based on the type of multi-AP coordination (such as C-SR, C-TDMA, C-Beamforming), the sharing APs or non-AP STAs sharing the resources transmit PPDUs in time, frequency or spatial domain.

[0429] The frames involved in the establishment of the multi-AP coordination set in this application include: multi-AP coordination set management frame, multi-AP coordination set setup or join request frame, multi-AP coordination set setup or join response frame, multi-AP coordination set parameter update notification frame.

[0430] In the embodiments of this application, the multi-AP coordination set management frame, the multi-AP coordination set setup or join request frame, and the multi-AP coordination set parameter update notification frame can include a multi-AP coordination set element.

[0431] Multi-AP coordination set element definition

[0432] The Multi-AP Coordination Set element can be carried in a management frame such as a beacon frame, a probe response frame, etc. for announcing the Multi-AP Coordination Set information; or the Multi-AP Coordination Set element can be carried in a Multi-AP Coordination Set establishment or join request frame for indicating the Multi-AP Coordination Set information for which establishment or join is requested, and / or the configuration information of the requesting AP or STA. The Multi-AP Coordination Set establishment or join response frame optionally includes the Multi-AP Coordination Set element.

[0489] Multi-AP coordination set establishment or join request frame format

[0490] The station (AP or non-AP STA) uses the multi-AP coordination set establishment or join request frame to negotiate the establishment or joining of the multi-AP coordination set. The action field of the multi-AP coordination set establishment or join request frame contains the information as shown in Table 2.

[0491] Table 2, example of action field format of multi-AP coordination set establishment or join request frame

[0492] The Protected UHR Action field contains 1 octet, which immediately follows the Category field, to distinguish the UHR Action frame format.

[0493] The Dialog Token field is set to a non-zero value selected by the station requesting to establish or join a Multi-AP Coordination Set, and is set to the value copied from the corresponding field in the received Multi-AP Coordination Set establishment or join request frame by its responding station.

[0494] The Multi-AP Coordination Set element can be as shown in Figure 15 or 16, can adopt the Request Multi-AP Coordination Set element variant format defined in the Multi-AP Coordination Set element format 1 or format 2. Wherein, the Multi-AP Coordination Set element carries the information of the Multi-AP Coordination Set requested to be established or joined, and / or the configuration information of the station requesting to establish or join the Multi-AP Coordination Set.

[0495] Optionally, if the Multi-AP Coordination Set element carries the information of the Multi-AP Coordination Set requested to be established, and at the same time, the requesting station is a coordinating AP, the Multi-AP Coordination Set establishment or join request frame Action field further includes the AP identifier or station identifier to be assigned to the target receiving station (or responding station) of the request frame.

[0496] Multi-AP Coordination Set establishment or join response frame format

[0497] The station AP or non-AP STA replies to the Multi-AP Coordination Set establishment or join request frame with the Multi-AP Coordination Set establishment or join response frame to reject or accept the Multi-AP Coordination Set establishment or join request. The Action field format of the Multi-AP Coordination Set establishment or join response frame can be as shown in Table 3.

[0498] Table 3, Action field format example of Multi-AP Coordination Set establishment or join response frame

[0499] The Protected UHR Action field contains 1 octet, which immediately follows the Category field, to distinguish the UHR Action frame format.

[0500] When the Multi-AP Coordination Set establishment or join response frame is sent as a response to the Multi-AP Coordination Set establishment or join request frame, the Dialog Token field in the Multi-AP Coordination Set establishment or join response frame is set to the value copied from the corresponding field in the received Multi-AP Coordination Set establishment or join request frame by the responding station. Wherein, the responding station is the target receiving station of the Multi-AP Coordination Set establishment or join request frame.

[0501] If the Multi-AP Coordination Set establishment or join response frame is not sent as a response to the Multi-AP Coordination Set establishment or join request frame, the Dialog Token field is set to a non-zero value selected by the station sending the corresponding response frame.

[0502] The status code field is used to indicate the status of the requested operation. The status code field is a 2-octet field. The status code field value definition for the multi-AP coordination set establishment or join response frame is shown in Table 4.

[0505] The format and encoding of the AP identification (AP ID) or STA identification (STA ID) is shown in Table (AID 12 / AP ID subfield encoding).

[0506] Optionally, the multi-AP coordination set establishment or join response frame can carry a multi-AP coordination set element to feedback the current established (or updated) multi-AP coordination set information. The definition of the multi-AP coordination set element is shown in Figure 15 or 16, which can adopt the basic multi-AP coordination set element variant format defined in the multi-AP coordination set element format 1 or format 2.

[0507] Multi-AP coordination set parameter update (or multi-AP coordination set STA join) announcement frame format definition

[0508] The AP adopts the multi-AP coordination set parameter update announcement frame to announce the configuration information of the stations associated with the coordinating AP (or the receiver of the announcement frame) participating in multi-AP cooperation. The information contained in the action field of the multi-AP coordination set parameter update (or multi-AP coordination set STA join) announcement frame is shown in Table 5.

[0510] The protected UHR action field contains 1 octet, which is immediately followed by the category field, and is used to distinguish the UHR action frame format.

[0511] The multi-AP coordination set element can be as shown in Figure 15 or Figure 16, wherein the multi-AP coordination set element carries the configuration information of the stations associated with the current AP (i.e. the sender of the announcement frame) participating in multi-AP cooperation.

[0512] Trigger frame general definition

[0513] The trigger frame based on the multi-AP cooperation is a control frame for cross-BSS operation, used for coordinating the AP (or sharing AP) to initiate multi-AP cooperation transmission, wherein the coordinating AP allocates resources to one or more coordinated APs of a BSS and / or non-AP STAs associated with the coordinating AP or the coordinated AP to transmit non-TB PPDU or TB PPDU; based on the type of multi-AP cooperation (such as C-SR, C-TDMA, C-BF), the APs or non-AP STAs sharing the resources share the resources in the time domain, frequency domain or space domain for PPDU transmission.

[0514] In the embodiments of the present application, the trigger frame based on multi-AP cooperation is used for the modification of the trigger frame format definition and the optimization of the access rule in the multi-AP cooperation scenario of cross-BSS operation, which includes:

[0515] 1) How to set the sending address and receiving address of the trigger frame, and how to indicate the coordinated AP and the non-AP STA associated with the coordinated AP or the coordinated AP in the cross-BSS.

[0516] 2) Enhancement of the channel access rule based on the trigger frame in the cross-BSS operation, such as how to handle the trigger frame after the scheduled coordinated AP and the non-AP STA associated with the coordinated AP or the coordinated AP receive the trigger frame, and how to reduce the overhead of the station receiving the cross-BSS control frame.

[0517] The frame format of the trigger frame can be as shown in FIG. 19, including the following fields: frame control (Frame Control), duration (Duration), receiving address (RA), sending address (TA), common information (Common Info), user information list (User Info List), intermediate frame check sequence (Frame Check Sequence, FCS), padding (Padding) and FCS.

[0518] The duration field is defined according to the (Duration / ID field (QoS STA)). The STA selects single protection and multiple protection when sending the first frame of the TXOP. The STA uses the same type of duration setting for all subsequent frames transmitted in the same TXOP.

[0519] The RA field is set as follows:

[0520] — For a trigger frame of non-GCR MU-BAR, NFRP or MU-RTS, if there is a User Info field, and the AID12 / APID subfield of the User Info field contains the AID of a non-AP STA associated with the coordinating AP or the AP ID of the coordinated AP (or scheduled AP) (the AP ID is assigned by the coordinating AP) or the STA ID of a non-AP STA associated with the coordinated AP (or scheduled AP) (the STA ID is assigned by the coordinating AP), the RA field is set to the corresponding address of the non-AP STA associated with the coordinating AP, or the address of the coordinated AP (or scheduled AP), or the address of the non-AP STA associated with the coordinated AP (or scheduled AP).

[0521] — For a trigger frame of non-GCR MU-BAR, NFRP or MU-RTS, if there is a User Info field, and the User Info field contains an APID subfield and an AID12 field (including the expected recipient of the User Info field or indicating the function of the User Info field), the RA field is set to the station corresponding to the AID12 subfield in the BSS of the AP indicated by the APID subfield, including associated stations or non-associated stations

[0522] — For a trigger frame with at least one User Info field with AID12 / APID subfield, when allocating RA-RU, the RA field is set to the broadcast address

[0523] — For a trigger frame of non-GCR MU-BAR, and a trigger frame with multiple User Info fields, the RA field is set to the broadcast address

[0524] — For a NFRP trigger frame or a MU-RTS trigger frame, the RA field is set to the broadcast address.

[0525] — For a GCR MU-BAR trigger frame, the RA field is set to the MAC address of the group of request receiving states.

[0526] The TA field is set as follows:

[0527] If the trigger frame is sent to the STA belonging to a single BSS, the TA field is the address of the STA sending the trigger frame. If the trigger frame is sent to the stations (including APs or non-AP STAs) from at least two different BSSs in a multi-AP coordination set, the TA field is the coordinating BSSID of the coordinating AP in the multi-AP coordination set. Wherein, the coordinating BSSID can be the MAC address of the coordinating AP, or the designated BSSID used by the coordinating AP to initiate multi-AP cooperation based on the multi-AP coordination set.

[0528] The intermediate FCS field contains a 32-bit CRC, where the intermediate FCS field value is computed over all fields in the MAC header and frame body up to and including the intermediate FCS field. The intermediate FCS field is used by the receiving STA to perform early validation of the information in the MAC header and frame body up to and including the intermediate FCS field.

[0529] The padding field is optionally present in a trigger frame to extend the frame length to give the receiving STA sufficient time to prepare a response to be sent SIFS after the frame is received. The length of the padding field, if present, is at least two octets and is set to all ones. If the padding field is present in a trigger frame, its length is computed as described in the existing table "Padding for Trigger Frames".

[0530] The FCS field contains a 32-bit CRC. The FCS field value is computed over all fields in the MAC header and frame body fields.

[0531] The user info list field contains zero or more user info fields.

[0532] 1. A field for indicating a value range of an AP ID and / or a field for indicating a value range of a STA ID can be selected from a reserved segment of the existing AID 12 field value, wherein the AP ID is an identification allocated by a coordinating AP for a coordinated AP, and the STA ID is an identification allocated by the coordinating AP for a station associated with the coordinated AP.

[0533] The UHR variant User Info field (UHR variant User Info field format) of the trigger frame is defined as shown in FIG. 20. An AP ID field is added, which, together with the AID 12 field, distinguishes the original AID 12 field definition based on different value ranges, and the AP ID corresponds to the identification of the STA ID.

[0534] The format of the UHR variant User Info field can be as shown in FIG. 20, including the following fields: AID 12 / AP ID, RU allocation (Allocation), uplink FEC coding type (UL FEC Coding Type), uplink EHT-MCS, reserved, SS allocation (SS Allocation), uplink target received power (UL Target Received Power), PS 160, and trigger dependent user info (Trigger dependent user info).

[0535] The encoding of the AID 12 / APID subfield in the User Info field is defined as shown in Table 6.

[0536] Table 6, example of AID 12 / APID subfield definition

[0537] 2、Optionally, a new definition of the User Info field is added, including the AID indication field, the APID field and / or the AID 11 field. According to the value of the AID indication field (which can be 1 bit, such as 1), the APID field and the AID 11 field jointly indicate the non-AP STA associated with the coordinated AP indicated by the APID field, i.e., the user field corresponds to the non-AP STA.

[0538] The UHR variant of the User Info field of the trigger frame is defined as shown in Figure 21, including the following subfields: AP ID, AID indication, AID 11, RU allocation, and allocation duration. The encoding of the APID subfield and the AID 11 subfield is shown in Table 7. Among them,

[0539] The APID field indicates the identity of the coordinated AP in the multi-AP coordination set (note: the identity is allocated by the coordinating AP), and the AID 11 field indicates the association identifier AID of the non-AP STA associated with the coordinated AP indicated by the APID field (note: the AID is allocated by the coordinated AP indicated by the APID field for the non-AP STA). The value of the AID 11 field can be (1-2007), which is consistent with the range of the existing AID 12 field indicating the associated STA.

[0540] The value range of the APID field can be consistent with the range of the AID 12 / APID field indicating the identity of the coordinated AP (AP ID), such as (2008-2030).

[0541] When the value of the AID indication field is 0, the user information field points to the coordinated AP indicated by the APID field, where the AP ID of the coordinated AP is allocated by the coordinating AP for the coordinated AP, and the AP ID is equal to the value in the APID subfield

[0542] When the value of the AID indication field is 1, the AID 11 field exists, and the APID field and the AID 11 field jointly indicate the non-AP STA associated with the coordinated AP indicated by the APID field, i.e., the user field corresponds to the non-AP STA, where the AID 11 field indicates the association identifier AID of the non-AP STA associated with the coordinated AP indicated by the APID field.

[0563] As shown in FIG. 25, it includes:

[0564] 1. After contending for the TXOP, AP1 initiates multi-AP coordination operations by sending a trigger frame, such as an MU RTS trigger frame or a buffer status report poll (BSRP) trigger frame, to AP1-STA and AP2, as well as AP2-STA. The settings of the fields of the trigger frame are as follows:

[0565] The transmission address (TA) field of the trigger frame is set to the coordination BSSID or MAC address of the coordinating AP (i.e., AP1) in the multi-AP coordination set, wherein the coordination BSSID is a designated BSSID used by AP1 to initiate multi-AP coordination-based multi-AP cooperation, and in particular, the coordination BSSID is designated for the multi-AP coordination set;

[0566] It contains a user information field pointing to AP2, and the value in the AID12 / APID subfield of the user information field is equal to the AP ID of AP2, wherein the AP ID of AP2 is allocated by AP1 for the AP2;

[0567] It contains a user information field pointing to AP2-STA, and the indication of AP2-STA can be in one of the following ways: 1) the user information field contains an AID12 / APID subfield, and the value in the AID12 / APID subfield of the user information field is equal to the STA ID of AP2-STA, wherein the STA ID of AP2-STA is allocated by AP1 for the STA; 2) the user information field contains an AID indication field, an APID field, and an AID11 field, wherein the value of the AID indication field is 1, the value of the APID field corresponds to the AP ID of AP2 (which is allocated by AP1), and the value of the AID11 field is the AID of AP2-STA (which is allocated by AP2);

[0568] includes a user info field pointing to the AP1-STA, the value in the AID 12 subfield of the user info field is equal to the AID of the AP1-STA, wherein the AID is assigned to the STA by the AP1.

[0569] 2. After receiving the trigger frame, the AP1-STA, the AP2, and the AP2-STA reply to the response of the trigger frame, for example, if the trigger frame is a MU RTS trigger frame, the response can be a CTS, indicating to accept to participate in the multi-AP coordination operation; if the trigger frame is a BSRP trigger frame, the response can be a buffer report BSR or other state report information, which can indicate to accept to participate in the multi-AP coordination operation and simultaneously carry the current state information (such as a BSR report or other channel available state information) and the like.

[0570] 3. If the AP2 and / or the AP2-STA indicate to participate in the CBF, the AP1 and the AP2 start the C-BF PPDU transmission after the SIFS of the response frame.

[0571] 4. After the SIFS of the CBF PPDU, the STAs associated with the two APs (the AP1-STA and the AP2-STA) respectively transmit their block acknowledgements (BAs) in a common TB PPDU.
