[0002] With the rapid development of mobile communication technology, Wireless Fidelity (Wi-Fi) technology has made great progress in terms of transmission rate and throughput. Currently, the content being studied by Wi-Fi technology includes, for example, 320Mhz bandwidth transmission, multi-frequency band aggregation and cooperation, etc., and its main application scenarios include, for example, video transmission, Augmented Reality (AR), Virtual Reality (VR), etc.

[0003] Specifically, multi-frequency band aggregation and cooperation means that devices communicate simultaneously in 2.4GHz, 5.8GHz, 6GHz and other frequency bands. For the scenario where devices communicate in multiple frequency bands simultaneously, it is necessary to define and manage a new Media Access Control (MAC) mechanism. Also, multi-frequency band aggregation and cooperation are expected to support low-latency transmission.

[0004] Currently, in multi-frequency band aggregation and cooperation technology, the maximum supported bandwidth is 320MHz (160MHz + 160MHz), and 240MHz (160MHz + 80MHz) and other bandwidths supported by existing standards may also be supported.

[0005] In currently researched Wi-Fi technologies, access point multilink devices (AP MLDs) that support multiple connections can add new attached APs at any time. Therefore, it is necessary to provide an implementation method for adding new attached APs in order to improve the management mechanism of attached APs and enhance local throughput.

[0019] Hereinafter, in conjunction with the drawings of the embodiments of this disclosure, the technical solutions of the embodiments of this disclosure will be clearly and completely described. It is obvious that the described embodiments are only some embodiments of this disclosure, not all embodiments. Based on the embodiments of this disclosure, those skilled in the art can obtain all other embodiments without creative efforts, which belong to the protection scope of this disclosure.

[0020] The embodiments of this disclosure provide a communication method, network devices, electronic devices, and storage media to provide an implementation method for adding a new attached AP.

[0021] The method and the apparatus are based on the concept of the same application. Since the problem-solving principles of the method and the apparatus are similar, the execution of the apparatus and the method can be referred to each other, and the description of the overlapping points will be omitted.

[0022] As shown in FIG. 1, embodiments of the present disclosure provide a communication method. Optionally, the method can be applied to an access point device (Access Point Multi-Link Device, AP MLD) that supports multi-link. This method can include the following steps 101-102.

[0023] In step 101, determine a target wireless frame, where the target wireless frame includes a Basic Multi-Link (Basic ML) information element, and the Basic ML information element includes a target identification bit, and the target identification bit indicates that the value of the maximum simultaneous link number field of the Basic ML information element has changed.

[0024] Generally, a Basic Multi-Link (Basic ML) element is used to carry information of a multi-link device (MLD) and its attached station device (Station, STA) in the multi-link discovery process. The AP MLD can identify whether a new attached AP has been added or an existing attached AP has been deleted by the Basic ML element. For example, an identification bit is included in the Basic ML element to indicate that the number of attached APs has changed.

[0025] Specifically, the AP MLD determines the target radio frame, which contains a Basic ML information element, which contains a target identification bit, which indicates that the value of the Maximum Number of Simultaneous Links field in the Basic ML information element has changed, indirectly identifying the addition of a new attached AP or the removal of an existing attached AP. For example, if the previously set Maximum Number of Simultaneous Links value was 4 and the subsequently set Maximum Number of Simultaneous Links value is 6, it identifies that two attached APs have been newly added. Conversely, if the previously set Maximum Number of Simultaneous Links value was 4 and the subsequently set Maximum Number of Simultaneous Links value is 3, it identifies that one attached AP has been removed.

[0026] Here, the Maximum Number of Simultaneous Links is carried to the MLD Capabilities and Operations subfield, and the MLD Capabilities and Operations subfield can be carried to the Common Info field in the Basic ML information element. As a first example, the format of the Common Info field in the Basic ML information element is shown in Table 1 below:

[0027] [Table 1]

[0028] Here, the Common Information Length subfield indicates the number of bytes in the Common Information field, the MLD MAC Address subfield indicates the MAC address of the MLD to which the STA transmitting the Basic ML belongs, and the Link ID Info subfield indicates the link identifier of the AP to which the AP MLD belongs.

[0029] The BSS Parameters Change Count subfield is one octet long, carries an unsigned integer, and has an initial value of 0. When a key update occurs, the value contained in the BSS Parameters Change Count subfield is updated to the AP operation parameter associated with the AP MLD.

[0030] The Medium Synchronization Delay Information subfield indicates the medium synchronization duration and the maximum number of medium synchronization transmission opportunities (TXOPs), among other things.

[0031] The EML Capabilities subfield indicates EMLSR operation and EMLMR (Enhanced Multi-Link Multi-Radio) capabilities.

[0032] The MLD Capabilities and Operations subfield indicates relevant information regarding MLD capabilities and operations, and the Maximum Number of Simultaneous Links may be included in this subfield.

[0033] The MLD identifier subfield indicates the identifier of the AP MLD that carries the MLD information to the Basic Multi-Link element.

[0034] In step 102, the target wireless frame is transmitted.

[0035] The target radio frame includes a beacon frame or a probe response frame, and the AP MLD can broadcast the target radio frame to identify that it has added a new associated AP or removed an existing associated AP.

[0036] In embodiments of the present disclosure, the AP MLD transmits the target radio frame including a Basic ML information element in the target radio frame, the Basic ML information element including a target identification bit, the target identification bit indicating that the value of the Maximum Simultaneous Links field in the Basic ML information element has changed, indirectly identifying the addition of a new attached AP or the removal of an existing attached AP, and embodiments of the present disclosure provide an implementation for adding a new attached AP or removing an existing attached AP, improving the attached AP management mechanism and improving local throughput.

[0037] Referring to Figure 2, embodiments of the present disclosure further provide a communication method, which can optionally be applied to an AP MLD, and this method may include the following steps:

[0038] In step 201, a target radio frame is determined, the target radio frame contains a basic multilink (Basic ML) information element, the Basic ML information element contains a target identification bit, the target identification bit indicates that the value of the maximum number of simultaneous links field of the Basic ML information element has changed, and the target identification bit is included in the presence bitmap subfield of the Basic ML information element.

[0039] Typically, Basic ML elements are used in the multilink discovery process to carry information about the MLD and its associated STAs. The AP MLD can identify when a new associated AP has been added or an existing associated AP has been removed by the Basic ML element, for example, by including an identification bit in the Basic ML element to indicate that the number of associated APs has changed.

[0040] Specifically, the AP MLD determines the target radio frame, the target radio frame contains a Basic ML information element, the Basic ML information element contains a target identification bit, the target identification bit indicates that the value of the Maximum Number of Simultaneous Links field of the Basic ML information element has changed, indirectly identifying the addition of a new attached AP or the removal of an existing attached AP, and furthermore, the target identification bit is included in the Presence Bitmap subfield of the Basic ML information element, and as a second example, the format of the Presence Bitmap subfield in the Basic ML information element is as shown in Table 2 below:

[0041] [Table 2]

[0042] The target identification bit can be carried to the MLD capability and operation present bit or hold bit.

[0043] In step 202, the target wireless frame is transmitted.

[0044] The target radio frame includes a beacon frame or a probe response frame, and the AP MLD can broadcast the target radio frame to identify that it has added a new associated AP or removed an existing associated AP.

[0045] In a selective embodiment, the Presence Bitmap subfield further includes Multilink Device Capabilities and Operations Present bits, The MLD Capabilities and Operations Present bit is set to a first preset parameter value, which indicates that the Multilink Device Capabilities and Operations subfield exists in the Basic ML information element. For example, if the first preset parameter value is 1, it indicates that the Common Info field of the Basic ML information element contains the MLD Capabilities and Operations subfield.

[0046] Referring to Figure 3, embodiments of the present disclosure further provide a communication method, which can optionally be applied to an AP MLD, and this method may include the following steps 301-302.

[0047] In step 301, the target wireless frame is determined, and the number of Link Info fields in the Basic Multilink (Basic ML) information element is adjusted based on the change in the value of the Maximum Simultaneous Links field. Here, the target wireless frame includes the Basic ML information element, the Basic ML information element includes a target identification bit, and the target identification bit indicates that the value of the maximum number of simultaneous links field of the Basic ML information element has changed.

[0048] Here, based on the difference between the current value of the Maximum Number of Simultaneous Links field and the value before AP MLD added or removed an attached AP, the number of Link Info fields in the Basic ML information element is added or decreased. For example, if the Maximum Number of Simultaneous Links set before AP MLD added an attached AP was 4, and the Maximum Number of Simultaneous Links set after it was added was 6, then two Link Info Fields need to be added in the Basic ML information element. Conversely, if the value of Maximum Number of Simultaneous Links set before was 4, and the value set after was 3, then one Link Info Field needs to be decreased in the Basic ML information element.

[0049] In step 302, the target wireless frame is transmitted.

[0050] The target radio frame includes a beacon frame or a probe response frame, and the AP MLD can broadcast the target radio frame to identify that it has added a new associated AP or removed an existing associated AP.

[0051] Referring to Figure 4, embodiments of the present disclosure further provide a communication method, which can optionally be applied to an AP MLD, and this method may include the following steps 401-402.

[0052] In step 401, the target wireless frame is determined, the number of Link Info domains in the Basic ML information element is added based on the change in the value of the Maximum Simultaneous Links field, and the content in the Link Info field is determined based on the associated AP corresponding to the added Link Info field.

[0053] Here, the target wireless frame includes the Basic ML information element, the Basic ML information element includes a target identification bit, and the target identification bit indicates that the value of the maximum number of simultaneous links field of the Basic ML information element has changed.

[0054] Here, based on the difference between the current value of the Maximum Number of Simultaneous Links field and the value before AP MLD added the attached AP, the number of Link Info fields in the Basic ML information element is increased. For example, if the Maximum Number of Simultaneous Links set before AP MLD added the attached AP was 4, and the Maximum Number of Simultaneous Links set after adding it is 6, then two Link Info fields need to be added in the Basic ML information element.

[0055] In step 402, the target radio frame is transmitted.

[0056] Here, the target radio frame includes a beacon frame or a probe response frame, and the AP MLD can broadcast the target radio frame to identify that it has added a new associated AP or removed an existing associated AP.

[0057] In a selective embodiment, the content in the Link Info field includes at least one of the following: link ID identification information for a first link corresponding to the attached AP; the Media Access Control Address (MAC) address of the attached AP in the first link; a Timer Synchronization Function (TSF) offset value Offset for a second link corresponding to a Beacon frame or Probe Response frame transmitted by the attached AP; the Beacon frame information; and the Probe Response frame information.

[0058] In embodiments of the present disclosure, the AP MLD transmits the target radio frame including a Basic ML information element in the target radio frame, the Basic ML information element including a target identification bit, the target identification bit indicating that the value of the Maximum Simultaneous Links field in the Basic ML information element has changed, indirectly identifying the addition of a new attached AP or the removal of an existing attached AP, and embodiments of the present disclosure provide an implementation for adding a new attached AP or removing an existing attached AP, improving the attached AP management mechanism and improving local throughput.

[0060] Typically, Basic Multi-Link (Basic ML) elements are used in the multi-link discovery process to carry information about multi-link devices (MLD) and their associated station devices (STA). AP MLDs can use Basic ML elements to identify when new associated APs have been added or when existing associated APs have been removed. For example, an identification bit can be included in the Basic ML element to indicate that the number of associated APs has changed.

[0061] Specifically, the AP MLD determines the target radio frame, which contains a Basic ML information element, which contains a target identification bit, which indicates that the value of the Maximum Number of Simultaneous Links field in the Basic ML information element has changed, indirectly identifying the addition of a new attached AP or the removal of an existing attached AP. For example, if the previously set Maximum Number of Simultaneous Links value was 4 and the subsequently set Maximum Number of Simultaneous Links value is 6, it identifies that two attached APs have been newly added. Conversely, if the previously set Maximum Number of Simultaneous Links value was 4 and the subsequently set Maximum Number of Simultaneous Links value is 3, it identifies that one attached AP has been removed.

[0062] Here, the Maximum Number of Simultaneous Links is included in the MLD Capabilities and Operations subfield, and the MLD Capabilities and Operations subfield may be included in the Common Info field in the Basic ML information element.

[0063] The transmitting module 502 transmits the target radio frame.

[0069] Selectively, in the embodiments of the present disclosure, the adjustment submodule adds a number of Link Info domains in the Basic ML information element and determines the content in the Link Info field based on the associated AP corresponding to the added Link Info field.
