[0035] In the embodiments of the present disclosure, the term "and / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent three situations: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0036] The term "plurality" in the embodiments of the present disclosure refers to two or more than two, and other quantifiers are similar thereto.

[0037] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. Unless otherwise indicated, when the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0038] The terms used in this disclosure are for the purpose of describing specific embodiments only and are not intended to limit the disclosure. The singular forms "a", "said" and "the" used in this disclosure and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0039] It should be understood that although the terms first, second, third, etc. may be used in the present disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, for example, the word "if" used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0040] After AP MLD and non-AP MLD negotiate and successfully establish multi-link setup, they can enable the established multi-link through the Traffic-To-Link Mapping mechanism and invalidate some enabled connections after enabling. In addition, AP MLD can add new subordinate APs or remove its subordinate APs to achieve communication connection reconfiguration between AP MLD and Non-APMLD. AP MLD's addition of enabled communication connections and newly added subordinate APs will increase the number of enabled communication connections or established communication connections between Non-AP MLD and AP MLD; invalidating enabled communication connections and removing subordinate APs will reduce the number of enabled communication connections or established communication connections between Non-AP MLD and AP MLD. In these cases, the device capability information of the STA attached to Non-AP MLD and the AP of AP MLD needs to be updated for better service transmission.

[0041] After the AP MLD adds or removes an attached AP, enables a communication connection, or invalidates an enabled communication connection, the Non-AP MLD initiates a multi-link operation parameter update (Multi-Link Operation Parameter Update) to update the operation parameters corresponding to the communication connection involved, such as updating the maximum message protocol data unit (Message Protocol Date Unit, MPDU) and aggregate message protocol data unit A-MSDU that can be received by the STA attached to the Non-AP MLD and the communication connection involved.

[0042] Specifically, the Non-AP MLD may send a multi-link operation update request frame (Multi-Link Operation Update Request frame) to the AP MLD for requesting a multi-link operation parameter update.

[0043] Among them, the multi-link operation update request frame includes at least one STA profile (Per-STA Profile) field, each Per-STA Profile field includes a STA Control field, the STA Control field includes a connection identification (Link ID) field, and each connection identification field indicates a communication connection through an identification value, which is used to request an update of the operation parameters corresponding to the communication connection, such as updating the device capability information of the STA corresponding to the communication connection.

[0044] The multi-link operation update request frame includes a reconfiguration multi-link information element (ReconfigurationMulti-Link element) field, the multi-link information element field includes a connection information (Link Info) field, and the connection information field includes one or more Per-STA Profile fields.

[0045] After receiving the request frame, the AP MLD informs the Non-AP MLD whether the request is successful through a message frame. According to the existing mechanism, when the Multi-Link Operation Update Request frame contains multiple communication connection operation parameter update requests, the AP MLD can only agree to all or reject all the operation parameter update requests contained in the Multi-Link Operation Update Request frame, and cannot selectively accept or reject a certain operation parameter update request.

[0046] To solve the above problems, the technical solutions in the embodiments of the present disclosure are clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0047] Among them, the method and the device are based on the same public concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0048] See also Figure 1 , Figure 1 is a schematic diagram of the system structure of multi-link communication provided by an embodiment of the present disclosure. The system architecture includes at least one AP MLD and at least one Non-AP MLD. The AP MLD includes multiple AP devices, such as Figure 1 The Non-AP MLD includes at least one STA device, such as Figure 1 STA1, STA2, ..., STAn shown in .

[0049] Among them, one or more communication connections can be established between the AP MLD and the Non-AP MLD, and each communication connection connects an AP device in the APMLD and an AP device in the Non-AP MLD.

[0050] After the AP MLD adds or removes an attached AP, enables a communication connection, or invalidates an enabled communication connection, the Non-AP MLD sends a multi-link operation update request frame to the AP MLD to update operation parameters corresponding to some of the involved communication connections.

[0051] For example, AP MLD removes multiple subordinate APs, and Non-AP MLD sends a multi-link operation update request frame to AP MLD to request a multi-link operation update, that is, to request an update of the operation parameters corresponding to the remaining communication connection between AP MLD and Non-AP MLD after removing the subordinate APs.

[0052] For AP MLD, AP MLD determines and sends a first message frame to Non-AP MLD, and responds to the operation parameter update request corresponding to each communication connection in the multi-link operation update request sent by Non-AP MLD through the first message frame. In addition, the first message frame is also used to indicate the number of communication connections corresponding to the operation parameter update request responded by AP MLD, that is, to indicate how many communication connections the AP MLD rejects and approves. Wherein, in the disclosed embodiment, the AP device can be a wireless switch for a wireless network and also an access device for the wireless network. The AP device can include software applications and / or circuits so that other types of nodes in the wireless network can communicate with the outside and inside of the wireless network through the AP device. As an example, the AP device can be a terminal device or a network device equipped with a Wi-Fi chip.

[0053] The STA device may specifically include, but is not limited to: a cellular phone, a smart phone, a wearable device, a computer, a personal digital assistant (PDA), a personal communication system (PCS) device, a personal information manager (PIM), a personal navigation device (PND), a global positioning system, a multimedia device, an Internet of Things (IoT) device, etc. The present disclosure provides a communication method that can be applied to an AP MLD. For details, see Figure 2 , Figure 2 It is a flow chart of a communication method provided by an embodiment of the present disclosure.

[0054] Optionally, the method may include the following steps:

[0055] Step S21, determine a first message frame, the first message frame includes a first information field, the first information field is used to indicate whether to agree or reject the operation parameter update request corresponding to each first communication connection, and is used to indicate the number of first communication connections; or, the first message frame includes a second information field and a third information field, the second information field is used to indicate whether to agree or reject the operation parameter update request corresponding to each first communication connection, and the third information field is used to indicate the number of first communication connections. In the embodiment of the present disclosure, each first communication connection is a communication connection for which a Non-AP MLD request is made to update multi-link operation parameters.

[0056] Among them, the first communication connection is the communication connection for which Non-AP MLD requests to update the multi-link operation parameters, including but not limited to the communication connection established between the AP device and the STA attached to the Non-AP MLD after the AP MLD adds an AP device, the remaining established communication connection between the AP device and the STA attached to the Non-AP MLD after the AP MLD removes the attached AP device, the enabled communication connection between the AP MLD and the Non-AP MLD, or the remaining communication connection between the invalid part of the AP MLD and the Non-AP MLD after the enabled connection, etc., are not limited here.

[0057] That is, for Non-AP MLD, Non-AP MLD needs to send a multi-link operation update request frame for the first communication connection to request an update of the operation parameters corresponding to each first communication connection, such as updating the device capability information of the STA device associated with each first communication connection.

[0058] Optionally, the first message frame includes a Category field, and the Category field indicates, through a first value, that the category of the first message frame is a Protected EHT Action category.

[0059] Optionally, the first message frame includes a protected extremely high throughput action (Protected EHT Action) field, and the protected extremely high throughput action field indicates through a second value that the first message frame is used to respond to a multi-link operation parameter update request (Multi-Link Operation Update Response).

[0060] Optionally, the first message frame also includes a dialog token field, the identification value of the dialog token field is the same as the identification value of the dialog token field in the multi-link operation update request frame sent by the Non-AP MLD, and is used to indicate that the first message frame and the multi-link operation update request frame belong to the same session, that is, to indicate that the first message frame is used to respond to the multi-link operation parameter update request.

[0061] Optionally, the first message frame may include a first information field, which indicates through the first information field whether the AP MLD agrees or rejects the operating parameter update request corresponding to each first communication connection, and the first information field may also indicate the number of first communication connections at the same time, that is, the first information field may indicate through the first information field how many operating parameter update requests of the first communication connections the AP MLD responds to.

[0062] As an example, when the first message frame includes the first information field, part of the information field in the first message frame may be as follows:

[0063] Category Protected EHT Action Dialog Token First information domain

[0064] Optionally, the first message frame may include a second information field and a third information field. The second information field may respectively indicate whether the AP MLD agrees or rejects the operating parameter update request corresponding to each first communication connection, and the third information field indicates the number of first communication connections, that is, the third information field may indicate how many operating parameter update requests of the first communication connections the AP MLD responds to.

[0065] As an example, when the first message frame includes the second information field and the third information field, part of the information fields in the first message frame may be as follows:

[0066] Category Protected EHT Action Dialog Token Second information field The third information domain

[0067] Step S22: Send a first message frame.

[0068] After determining the first message frame, the Non-AP MLD may send the first message frame to the Non-AP MLD, where the first message frame is used to respond to the multi-link operation update request frame.

[0069] In the communication method applied to AP MLD provided by the embodiment of the present disclosure, when the first message frame includes the first information field, the first information field includes an Update Status Info Control field and an Update Status Info List field.

[0070] The update status information control field is used to indicate the number of first communication connections, and the update status information list field is used to respectively instruct the AP MLD to approve or reject the operation parameter update request corresponding to each first communication connection.

[0071] That is to say, for AP MLD, AP MLD sends a first message frame, the first message frame includes a first information field, AP MLD indicates the number of first communication connections through the update status information control field in the first information field, and indicates AP MLD whether to agree or reject the operation parameter update request corresponding to each first communication connection through the update status information list field in the first information field.

[0072] As an example, part of the information field in the first information field may be as follows:

[0073] Update Status Info Control Update Status Info List

[0074] In the communication method applied to AP MLD provided by an embodiment of the present disclosure, when the first message frame includes a first information field, the first information field includes an update status information control field, the update status information control field includes an update status number (Update Status Count) field, and the update status number field is used to indicate the number of first communication connections.

[0075] The number indicated by the update status quantity field is consistent with the number of Per-STAProfile fields or link ID fields included in the multi-link operation update request frame.

[0076] The number of first communication connections indicated by the update status quantity field is consistent with the number of Per-STA Profile fields or link ID fields included in the multi-link operation update request frame.

[0077] As an example, the update status information control field may be as follows:

[0078] Update Status Count Reserved

[0079] Among them, Reserved is a reserved bit.

[0080] In the communication method applied to AP MLD provided by an embodiment of the present disclosure, when the first message frame includes a first information field, the first information field includes an update status number (Update Status Count) field and an update status information list (Update Status Info List) field, the update status number field is used to indicate the number of first communication connections, and the update status information list field is used to respectively indicate whether the AP MLD agrees or rejects the operation parameter update request corresponding to each first communication connection.

[0081] The number indicated by the update status quantity field is consistent with the number of Per-STAProfile fields or link ID fields included in the multi-link operation update request frame.

[0082] As an example, part of the information field in the first information field may be as follows:

[0083] Update Status Count Update Status Info List

[0084] In the communication method applied to AP MLD provided by an embodiment of the present disclosure, when the first message frame includes a first information field, that is, when the AP MLD indicates through the first information field in the first message frame that the AP MLD agrees or rejects the operation parameter update request corresponding to each first communication connection, and the number of first communication connections, the first message field can be an update status information (Update Status Info) field.

[0085] As an example, part of the information field in the first message frame may be as follows:

[0086] Category Protected EHT Action Dialog Token Update Status Info

[0087] In the communication method applied to AP MLD provided by the embodiment of the present disclosure, when the first message frame includes the second information field and the third information field, the second information field is the update status information list (Update Status Info List) field, and the third information field is the update status number (Update Status Count) field.

[0088] When the first message frame includes an update status information list field and an update status quantity field, the AP MLD indicates through the update status information list field whether the AP MLD agrees or rejects the operation parameter update request corresponding to each first communication connection, and indicates the number of first communication connections through the update status quantity field.

[0089] As an example, part of the information field of the first message frame may be as follows:

[0090]

[0091] The number of first communication connections indicated by the update status quantity field is consistent with the number of Per-STA Profile fields or link ID fields included in the multi-link operation update request frame.

[0092] In the communication method applied to AP MLD provided in an embodiment of the present disclosure, the first information field or the second information field may include at least one single connection update status information (Per-Link Update Status Info) field, and each single connection update status information field is used to indicate whether the AP MLD agrees or rejects an operation parameter update request corresponding to a first communication connection.

[0093] Among them, the number of single connection update status information fields in the first information field or the second information field is the same as the number of first communication connections, that is, the number of single connection update status information fields in the first information field or the second information field is consistent with the number of Per-STA Profile fields or link ID fields included in the multi-link operation update request frame.

[0094] As an example, the first information field or the second information field may include multiple single connection update state information fields, each single connection update state information field is used to indicate an operation parameter update request corresponding to a first communication connection, and the first information field may be as follows:

[0095]

[0096] In the communication method applied to AP MLD provided by the embodiment of the present disclosure, each single connection update status information field includes a connection information (Link Info) field and a status (Status) field.

[0097] Among them, the connection information field is used to indicate a connection identifier of a first communication connection, and the status field indicates through a first value that the AP MLD agrees to the operation parameter update request corresponding to the first communication connection indicated by the connection identifier, and through a second value that the AP MLD rejects the operation parameter update request corresponding to the first communication connection indicated by the connection identifier.

[0098] That is to say, for each single connection update status information domain, the single connection update status information domain can indicate a connection identifier of a first communication connection through the connection information domain, and the single connection update status information domain indicates through the identification value of the status field that the AP MLD rejects or agrees to the operation parameter update request corresponding to the first communication connection indicated by the connection identifier.

[0099] The first value and the second value are different values, which are not limited here. For example, the first value may be 0, and the second value may be 141.

[0100] As an example, when the first value is 0 and the second value is 141, for any single connection update status information domain, if the first communication connection indicated by the connection identifier of the connection information domain of the single connection update status information domain is link1, when the identification value of the status field in the single connection update status information domain is 141, it indicates that the AP MLD rejects the operation parameter update request (DENIED_OPERATION_PARAMETER_UPDATE) corresponding to link1; when the identification value of the status field in the single connection update status information domain is 0, it indicates that the AP MLD agrees to the operation parameter update request corresponding to link1.

[0101] As an example, the single connection update status information field may be as follows:

[0102] Link Info Status

[0103] Among them, the identification value of the connection information field in each single connection update status information field is consistent with the identification value of a link ID field in the Per-STA Profile field included in the multi-link operation update request frame, that is, the connection identifier indicated by the connection information field in each single connection update status information field corresponds to a first communication connection.

[0104] In the communication method applied to AP MLD provided by the embodiment of the present disclosure, the first information field or the second information field includes an update status information list (Update Status Info List) field, and the update status information list field includes at least one single connection update status information field.

[0105] Among them, the number of single-connection update status information fields in the update status information list field is the same as the number of first communication connections, that is, the number of single-connection update status information fields in the update status information list field is consistent with the number of Per-STA Profile fields or link ID fields included in the multi-link operation update request frame.

[0106] As an example, AP MLD sends a first message frame. When the first message frame includes a first information field, the first information field includes an update status information list field. The update status information list field includes at least one single connection update status information field. Each single connection update status information field is used to indicate that AP MLD agrees or rejects an operation parameter update request corresponding to a first communication connection.

[0107] As an example, AP MLD sends a first message frame. When the first message frame includes a first information field, the first information field is an update status information field. The update status information field includes an update status information list field. The update status information list field includes at least one single connection update status information field. Each single connection update status information field is used to indicate that AP MLD agrees or rejects an operation parameter update request corresponding to a first communication connection.

[0108] As an example, when the AP MLD sends a first message frame, and the first message frame includes a second information field and a third information field, the second information field is an update status information list field, and the update status information list field includes at least one single connection update status information field, and each single connection update status information field is used to indicate that the AP MLD agrees or rejects an operation parameter update request corresponding to a first communication connection. That is, the first message frame is used to indicate that the AP MLD agrees or rejects an operation parameter update request corresponding to a first communication connection through each single connection update status information field in the second information field, and indicates the number of first communication connections through the third information field.

[0109] In the communication method applied to AP MLD provided in the embodiment of the present disclosure, the first message frame is a multi-link operation update response frame (Multi-Link Operation Update Response frame). That is, after receiving the multi-link operation update request frame sent by the Non-AP MLD, the AP MLD sends a multi-link operation update response frame to the Non-AP MLD, and instructs the AP MLD to agree or reject the operation parameter update request corresponding to each first communication connection through the multi-link operation update response frame.

[0110] It should be particularly noted that, in the communication method applied to AP MLD provided in the embodiment of the present disclosure, when the first message frame includes the first information field, the first information field may specifically indicate the number of the first communication connection through the update status number field, and the first information field may directly include the update status number field, or the first information field includes the update status information control field, and the update status number field is included in the update status information control field. At the same time, the first information field may directly include at least one single connection update status information field, and may also include an update status information list field, and at least one single connection update status information field is included in the update status information list field, so as to indicate to the AP MLD through each single connection update status information field whether to agree or reject the operation parameter update request corresponding to the first communication connection.

[0111] In the case where the first message frame includes the second information field and the third information field, the second information field may directly include at least one single connection update state information field, or may include an update state information list field, wherein the update state information list field includes at least one single connection update state information field, so as to indicate to the AP MLD through each single connection update state information field whether to approve or reject the operation parameter update request corresponding to the first communication connection. At the same time, the number of the first communication connections is indicated through the third information field.

[0112] The communication method provided in the embodiment of the present disclosure can be applied to Non-AP MLD. Figure 3 , Figure 3It is another flowchart of the communication method provided by an embodiment of the present disclosure.

[0113] Optionally, the method may include the following steps:

[0114] Step S31: receiving a first message frame, the first message frame including a first information field, the first information field being used to indicate whether the AP MLD approves or rejects an operation parameter update request corresponding to each first communication connection, and being used to indicate the number of first communication connections; or,

[0115] The first message frame includes a second information field and a third information field, the second information field is used to indicate the AP MLD to approve or reject the operation parameter update request corresponding to each first communication connection, and the third information field is used to indicate the number of the first communication connections.

[0116] In the embodiment of the present disclosure, each first communication connection is a communication connection for which the Non-AP MLD requests to update multi-link operation parameters.

[0117] Among them, the first communication connection is the communication connection for Non-AP MLD to request multi-link operation parameter update, including but not limited to the communication connection established between the AP device and the STA attached to the Non-AP MLD after the AP MLD adds an AP device, the communication connection established between the AP device and the STA attached to the Non-AP MLD before the AP MLD removes the attached AP device, the communication connection between the AP MLD enabled and the Non-AP MLD, or the communication connection between the AP MLD and the Non-AP MLD when the enabled communication is invalid, etc., and no limitation is made here.

[0118] That is, for Non-AP MLD, Non-AP MLD needs to send a multi-link operation update request frame for the first communication connection to request an update of the operation parameters corresponding to each first communication connection, such as updating the device capability information of the STA device associated with each first communication connection.

[0119] Optionally, the first message frame includes a Category field, and the Category field indicates, through a first value, that the category of the first message frame is a Protected EHT Action category.

[0120] Optionally, the first message frame includes a protected extremely high throughput action (Protected EHT Action) field, and the protected extremely high throughput action field indicates through a second value that the first message frame is used to respond to a multi-link operation parameter update request (Multi-Link Operation Update Response).

[0121] Optionally, the first message frame also includes a dialog token field, the identification value of the dialog token field is the same as the identification value of the dialog token field in the multi-link operation update request frame sent by the Non-AP MLD, and is used to indicate that the first message frame and the multi-link operation update request frame belong to the same session, that is, to indicate that the first message frame is used to respond to the multi-link operation parameter update request.

[0122] Optionally, the first message frame may include a first information field, which indicates through the first information field whether the AP MLD agrees or rejects the operating parameter update request corresponding to each first communication connection, and the first information field may also indicate the number of first communication connections at the same time, that is, the first information field may indicate through the first information field how many operating parameter update requests of the first communication connections the AP MLD responds to.

[0123] As an example, when the first message frame includes the first information field, part of the information field in the first message frame may be as follows:

[0124] Category Protected EHT Action Dialog Token First information domain

[0125] Optionally, the first message frame may include a second information field and a third information field. The second information field may respectively indicate whether the AP MLD agrees or rejects the operating parameter update request corresponding to each first communication connection, and the third information field indicates the number of first communication connections, that is, the third information field may indicate how many operating parameter update requests of the first communication connections the AP MLD responds to.

[0126] As an example, when the first message frame includes the second information field and the third information field, part of the information fields in the first message frame may be as follows:

[0127] Category Protected EHT Action Dialog Token Second information field The third information domain

[0128] In the communication method applied to Non-AP MLD provided by the embodiment of the present disclosure, when the first message frame includes the first information field, the first information field includes an Update Status Info Control field and an Update Status Info List field.

[0129] The update status information control field is used to indicate the number of first communication connections, and the update status information list field is used to respectively instruct the AP MLD to approve or reject the operation parameter update request corresponding to each first communication connection.

[0130] That is to say, for AP MLD, AP MLD sends a first message frame, the first message frame includes a first information field, AP MLD indicates the number of first communication connections through the update status information control field in the first information field, and indicates AP MLD whether to agree or reject the operation parameter update request corresponding to each first communication connection through the update status information list field in the first information field.

[0131] As an example, part of the information field in the first information field may be as follows:

[0132] Update Status Info Control Update Status Info List

[0133] In the communication method applied to Non-AP MLD provided by an embodiment of the present disclosure, when the first message frame includes a first information field, the first information field includes an update status information control field, the update status information control field includes an update status number (Update Status Count) field, and the update status number field is used to indicate the number of first communication connections.

[0134] The number indicated by the update status quantity field is consistent with the number of Per-STAProfile fields or link ID fields included in the multi-link operation update request frame.

[0135] The number of first communication connections indicated by the update status quantity field is consistent with the number of Per-STA Profile fields or link ID fields included in the multi-link operation update request frame.

[0136] As an example, the update status information control field may be as follows:

[0137] Update Status Count Reserved

[0138] Among them, Reserved is a reserved bit.

[0139] In the communication method applied to Non-AP MLD provided by an embodiment of the present disclosure, when the first message frame includes a first information field, the first information field includes an update status number (Update Status Count) field and an update status information list (Update Status Info List) field, the update status number field is used to indicate the number of first communication connections, and the update status information list field is used to respectively indicate whether the AP MLD agrees or rejects the operation parameter update request corresponding to each first communication connection.

[0140] The number indicated by the update status quantity field is consistent with the number of Per-STAProfile fields or link ID fields included in the multi-link operation update request frame.

[0141] As an example, part of the information field in the first information field may be as follows:

[0142] Update Status Count Update Status Info List

[0143] In the communication method applied to Non-AP MLD provided in an embodiment of the present disclosure, when the first message frame includes a first information field, that is, the AP MLD indicates through the first information field in the first message frame that the AP MLD agrees or rejects the operation parameter update request corresponding to each first communication connection, and the number of first communication connections, the first message field can be an update status information (Update Status Info) field.

[0144] As an example, part of the information field in the first message frame may be as follows:

[0145] Category Protected EHT Action Dialog Token Update Status Info

[0146] In the communication method applied to Non-AP MLD provided by the embodiment of the present disclosure, when the first message frame includes the second information field and the third information field, the second information field is the update status information list (Update Status InfoList) field, and the third information field is the update status number (Update Status Count) field.

[0147] When the first message frame includes an update status information list field and an update status quantity field, the AP MLD indicates through the update status information list field whether the AP MLD agrees or rejects the operation parameter update request corresponding to each first communication connection, and indicates the number of first communication connections through the update status quantity field.

[0148] As an example, part of the information field of the first message frame may be as follows:

[0149]

[0150] The number of first communication connections indicated by the update status quantity field is consistent with the number of Per-STA Profile fields or link ID fields included in the multi-link operation update request frame.

[0151] In the communication method applied to Non-AP MLD provided in an embodiment of the present disclosure, the first information field or the second information field may include at least one single connection update status information (Per-Link Update Status Info) field, and each single connection update status information field is used to indicate whether the AP MLD agrees or rejects an operation parameter update request corresponding to a first communication connection.

[0152] Among them, the number of single connection update status information fields in the first information field or the second information field is the same as the number of first communication connections, that is, the number of single connection update status information fields in the first information field or the second information field is consistent with the number of Per-STA Profile fields or link ID fields included in the multi-link operation update request frame.

[0153] As an example, the first information field or the second information field may include multiple single connection update state information fields, each single connection update state information field is used to indicate an operation parameter update request corresponding to a first communication connection, and the first information field may be as follows:

[0154]

[0155] In the communication method applied to Non-AP MLD provided by the embodiment of the present disclosure, each single connection update status information field includes a connection information (Link Info) field and a status (Status) field.

[0156] Among them, the connection information field is used to indicate a connection identifier of a first communication connection, and the status field indicates through a first value that the AP MLD agrees to the operation parameter update request corresponding to the first communication connection indicated by the connection identifier, and through a second value that the AP MLD rejects the operation parameter update request corresponding to the first communication connection indicated by the connection identifier.

[0157] That is to say, for each single connection update status information domain, the single connection update status information domain can indicate a connection identifier of a first communication connection through the connection information domain, and the single connection update status information domain indicates through the identification value of the status field that the AP MLD rejects or agrees to the operation parameter update request corresponding to the first communication connection indicated by the connection identifier.

[0158] The first value and the second value are different values, which are not limited here. For example, the first value may be 0, and the second value may be 141.

[0159] As an example, when the first value is 0 and the second value is 141, for any single connection update status information domain, if the first communication connection indicated by the connection identifier of the connection information domain of the single connection update status information domain is link1, when the identification value of the status field in the single connection update status information domain is 141, it indicates that the AP MLD rejects the operation parameter update request (DENIED_OPERATION_PARAMETER_UPDATE) corresponding to link1; when the identification value of the status field in the single connection update status information domain is 0, it indicates that the AP MLD agrees to the operation parameter update request corresponding to link1.

[0160] As an example, the single connection update status information field may be as follows:

[0161] Link Info Status

[0162] Among them, the identification value of the connection information field in each single connection update status information field is consistent with the identification value of a link ID field in the Per-STA Profile field included in the multi-link operation update request frame, that is, the connection identifier indicated by the connection information field in each single connection update status information field corresponds to a first communication connection.

[0163] In the communication method applied to the Non-AP MLD provided by the embodiment of the present disclosure, the first information field or the second information field includes an update status information list (Update Status Info List) field, and the update status information list field includes at least one single connection update status information field.

[0164] Among them, the number of single-connection update status information fields in the update status information list field is the same as the number of first communication connections, that is, the number of single-connection update status information fields in the update status information list field is consistent with the number of Per-STA Profile fields or link ID fields included in the multi-link operation update request frame.

[0165] As an example, AP MLD sends a first message frame. When the first message frame includes a first information field, the first information field includes an update status information list field. The update status information list field includes at least one single connection update status information field. Each single connection update status information field is used to indicate that AP MLD agrees or rejects an operation parameter update request corresponding to a first communication connection.

[0166] As an example, AP MLD sends a first message frame. When the first message frame includes a first information field, the first information field is an update status information field. The update status information field includes an update status information list field. The update status information list field includes at least one single connection update status information field. Each single connection update status information field is used to indicate that AP MLD agrees or rejects an operation parameter update request corresponding to a first communication connection.

[0167] As an example, when the AP MLD sends a first message frame, and the first message frame includes a second information field and a third information field, the second information field is an update status information list field, and the update status information list field includes at least one single connection update status information field, and each single connection update status information field is used to indicate that the AP MLD agrees or rejects an operation parameter update request corresponding to a first communication connection. That is, the first message frame is used to indicate that the AP MLD agrees or rejects an operation parameter update request corresponding to a first communication connection through each single connection update status information field in the second information field, and indicates the number of first communication connections through the third information field.

[0168] In the communication method applied to Non-AP MLD provided in the embodiment of the present disclosure, the first message frame is a multi-link operation update response frame (Multi-Link Operation Update Response frame). That is, after receiving the multi-link operation update request frame sent by Non-APMLD, AP MLD sends a multi-link operation update response frame to Non-AP MLD, and instructs AP MLD to agree or reject the operation parameter update request corresponding to each first communication connection through the multi-link operation update response frame.

[0169] It should be particularly noted that in the communication method applied to Non-AP MLD provided in the embodiment of the present disclosure, when the first message frame includes the first information field, the first information field can specifically indicate the number of the first communication connection through the update status number field, and the first information field can directly include the update status number field, or the first information field includes the update status information control field, and the update status number field is included in the update status information control field. At the same time, the first information field can directly include at least one single connection update status information field, and can also include an update status information list field, and the update status information list field includes at least one single connection update status information field, so as to indicate that the APMLD agrees or rejects the operation parameter update request corresponding to the first communication connection through each single connection update status information field.

[0170] In the case where the first message frame includes the second information field and the third information field, the second information field may directly include at least one single connection update state information field, or may include an update state information list field, wherein the update state information list field includes at least one single connection update state information field, so as to indicate to the AP MLD through each single connection update state information field whether to approve or reject the operation parameter update request corresponding to the first communication connection. At the same time, the number of the first communication connections is indicated through the third information field.

[0171] As an example, the following Figure 4 The communication method provided in the embodiment of the present disclosure is further described.

[0172] After the AP MLD and the Non-AP MLD negotiate and successfully establish multiple connections, the AP MLD and the Non-AP MLD can communicate and interact with each other.

[0173] After the AP MLD adds or removes an attached AP, enables a communication connection, or invalidates an enabled communication connection, the Non-AP MLD may initiate a multi-link operation parameter update (Multi-Link Operation Parameter Update) through a multi-link operation update request frame to update the operation parameters corresponding to the communication connection involved.

[0174] Among them, the multi-link operation update request frame includes at least one STA profile (Per-STA Profile) field, each Per-STA Profile field includes a STA Control field, the STA Control field includes a connection identification (Link ID) field, and each connection identification field indicates a first communication connection through an identification value, which is used to request an update of the operation parameters corresponding to the first communication connection.

[0175] Among them, the first communication connection is the communication connection for which Non-AP MLD requests to update the multi-link operation parameters, including but not limited to the communication connection established between the AP device and the STA attached to the Non-AP MLD after the AP MLD adds an AP device, the remaining established communication connection between the AP device and the STA attached to the Non-AP MLD after the AP MLD removes the attached AP device, the enabled communication connection between the AP MLD and the Non-AP MLD, or the remaining communication connection between the invalid part of the AP MLD and the Non-AP MLD after the enabled connection, etc., are not limited here.

[0176] The multi-link operation update request frame includes a reconfiguration multi-link information element field, the reconfiguration multi-link information element field includes a connection information (Link Info) field, and the connection information field includes a Per-STA Profile field.

[0177] After receiving the request frame, the AP MLD determines and sends a multi-link operation update response frame to the Non-AP MLD.

[0178] The multi-link operation update response frame includes a Category field, and the Category field indicates that the category of the multi-link operation update response frame is a Protected EHT Action category through a first value.

[0179] The multi-link operation update response frame includes a protected extremely high throughput action (Protected EHT Action) field, and the protected extremely high throughput action field indicates through a second value that the multi-link operation update response frame is used to respond to a multi-link operation parameter update request (Multi-Link Operation Update Response).

[0180] Among them, the multi-link operation update response frame also includes a dialogue token (Dialog Token) field, the identification value of the dialogue token field is the same as the identification value of the dialogue token field in the multi-link operation update request frame sent by the Non-AP MLD, and is used to indicate that the multi-link operation update response frame and the multi-link operation update request frame belong to the same session, that is, to indicate that the multi-link operation update response frame is used to respond to the multi-link operation parameter update request.

[0181] In one implementation, the multi-link operation update response frame includes an update status information field, the update status information field includes a status information control field, the status information control field includes an update status quantity field, and the multi-link operation update response frame indicates the number of first communication connections through the update status quantity field.

[0182] The update status information field in the multi-link operation update response frame also includes an update status information list field, the update status information list field includes at least one single connection update status information field, and each single connection update status information field is used to indicate an operation parameter update request corresponding to a first communication connection.

[0183] In one implementation, the multi-link operation update response frame includes an update status quantity field and an update status information list field. The multi-link operation update response frame indicates the number of first communication connections through the update status quantity field. The update status information list field includes at least one single connection update status information field. Each single connection update status information field is used to indicate an operation parameter update request corresponding to a first communication connection.

[0184] In any of the above implementations, each single connection update status information field includes a link information (Link Info) field and a status (Status) field. The link information field is used to indicate a connection identifier of a first communication connection, and the status field indicates that the AP MLD agrees to the operation parameter update request corresponding to the first communication connection indicated by the link information field through a first value, and indicates that the AP MLD rejects the operation parameter update request corresponding to the first communication connection indicated by the link information field through a second value.

[0185] Among them, the first value can be 0, and the second value can be 141. For any single connection update state information domain, if the identification value of the status field in the single connection update state information domain is 141, it is used to indicate that the AP MLD rejects the operation parameter update request (DENIED_OPERATION_PARAMETER_UPDATE) corresponding to the first communication connection indicated by the connection information field in the same single connection update state information domain; if the identification value of the status field in the single connection update state information domain is 0, it is used to indicate that the AP MLD agrees to the operation parameter update request corresponding to the first communication connection indicated by the connection information field in the same single connection update state information domain.

[0186] Among them, the identification value of the connection information field in each single connection update status information field is the same as the identification value of a link ID field in the multi-link operation update request frame, and the number of Per-STA Profile fields in the multi-link operation update request frame is the same as the number of first communication connections, each Per-STA Profile field includes a STA Control field, and the STA Control field of each Per-STA Profile field indicates a first communication connection through the identification value of a link ID field.
