Description

Technical Field

Background Art

[0002] With the rapid development of mobile communication technologies, 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 mean that devices communicate simultaneously in frequency bands such as 2.4GHz, 5.8GHz, 6GHz, and other frequency bands. For scenarios where devices communicate simultaneously in multiple frequency bands, 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 technologies, 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 the currently studied Wi-Fi technology, for an access point multi-link device (AP MLD) that supports multi-connection, new attached APs can be added at any time. Therefore, it is necessary to provide a realization method for adding new attached APs in order to improve the management mechanism of the attached APs and enhance the 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 work, 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 a realization 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 that supports multi-link (Access Point Multi-Link Device, AP MLD). This method can include the following steps 101 to 102.

[0023] In step 101, a target wireless frame is determined. The target wireless frame includes a Basic Multi-Link (Basic ML) information element. The Basic ML information element includes a target identification bit. 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, by including an identification bit in the Basic ML element, it indicates that the number of attached APs has changed.

[0025] Specifically, the AP MLD determines a target wireless frame. The target wireless frame includes a Basic ML information element, and the Basic ML information element includes a target identification bit. The target identification bit 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 deletion of an existing attached AP. For example, if the previously set value of the Maximum Number Of Simultaneous Links is 4 and the subsequently set value of the Maximum Number Of Simultaneous Links is 6, it is identified that two attached APs have been newly added. Conversely, if the previously set value of the Maximum Number Of Simultaneous Links is 4 and the subsequently set value of the Maximum Number Of Simultaneous Links is 3, it is identified that one attached AP has been deleted.

[0026] Here, the Maximum Number Of Simultaneous Links is carried in the MLD Capabilities And Operations subfield, and the MLD Capabilities And Operations subfield can be carried in 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 as 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 that transmits Basic ML belongs, and the Link ID Info subfield indicates the link identifier of the AP to which the AP MLD belongs.

[0029] The length of the BSS Parameters Change Count subfield is one octet, carrying an unsigned integer, and the initial value is 0. When a key update occurs, the value contained in the BSS Parameters Change Count subfield is updated to the operation parameters of the AP 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), etc.

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

[0032] The MLD capabilities and operations subfield indicates information related to MLD capabilities and operations, and the Maximum Number Of Simultaneous Links can be included in this subfield.

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

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

[0035] The target wireless frame includes a Beacon frame or a Probe Response frame, and the AP MLD can broadcast the target wireless frame to identify whether it has added a new attached AP or deleted an existing attached AP.

[0036] In an embodiment of the present disclosure, the AP MLD includes a Basic ML information element in the target wireless frame and transmits the target wireless frame. The Basic ML information element includes a target identification bit, and the target identification bit indicates that the value of the maximum simultaneous link count field of the Basic ML information element has changed, indirectly identifying the addition of a new attached AP or the deletion of an existing attached AP. The embodiment of the present disclosure provides a realization method for adding a new attached AP or deleting an existing attached AP, improves the management mechanism of the attached AP, and improves the local throughput.

[0037] Referring to FIG. 2, an embodiment of the present disclosure further provides a communication method. Optionally, the method can be applied to an AP MLD. This method can include the following steps.

[0038] In step 201, determine a target wireless frame, where the target wireless frame includes a Basic Multi-Link (Basic ML) information element, the Basic ML information element includes a target identification bit, the target identification bit indicates that the value of the maximum simultaneous link count 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 to carry information of MLD and its attached STAs 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 elements. For example, by including identification bits in the Basic ML elements, it indicates that the number of attached APs has changed.

[0040] Specifically, the AP MLD determines the target wireless frame, the Basic ML information element is included in the target wireless frame, the target identification bit is included in the Basic ML information element, and the target identification bit 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 deletion of an existing attached AP. Furthermore, the target identification bit is included in the Presence Bitmap sub-field of the Basic ML information element. As a second example, the format of the Presence Bitmap sub-field in the Basic ML information element is as shown in Table 2 below:

[0041]

Table 2

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

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

[0044] The target wireless frame includes a Beacon frame or a Probe Response frame, and the AP MLD broadcasts the target wireless frame to identify whether it has added a new attached AP or deleted an existing attached AP.

[0045] In an alternative embodiment, the Presence Bitmap subfield further includes Multi-Link Device Capabilities and Operations Present bits. The Multi-Link Device Capabilities and Operations Present bits are set to a first preset parameter value, and the first preset parameter value indicates the presence of Multi-Link Device Capabilities and Operations (MLD Capabilities and Operations subfield) in the Basic ML information element. For example, when the first preset parameter value is 1, it is identified that the MLD Capabilities and Operations subfield is included in the Common Info field of the Basic ML information element.

[0046] Referring to FIG. 3, an embodiment of the present disclosure further provides a communication method. Optionally, the method can be applied to an AP MLD, and this method can include the following steps 301 to 302.

[0047] In step 301, a target wireless frame is determined, and based on the change amount of the value of the maximum simultaneous link number field, the number of Link Info fields in the Basic Multi-Link (Basic ML) information element is adjusted. Here, the Basic ML information element is included in the target wireless frame, the target identification bit is included in the Basic ML information element, and the target identification bit indicates that the value of the maximum simultaneous link number 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 the AP MLD adds or deletes an attached AP, increase or decrease the number of Link Info fields in the Basic ML information element. For example, if the Maximum Number Of Simultaneous Links set before the AP MLD adds an attached AP is 4 and the Maximum Number Of Simultaneous Links set after the addition is 6, it is necessary to add two Link Info Fields in the Basic ML information element. Conversely, if the value in the previously set Maximum Number Of Simultaneous Links is 4 and the value in the subsequently set Maximum Number Of Simultaneous Links is 3, it is necessary to decrease one Link Info Field in the Basic ML information element.

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

[0050] The target wireless frame includes a Beacon frame or a Probe Response frame, and the AP MLD can broadcast the target wireless frame to identify whether it has added a new attached AP or deleted an existing attached AP.

[0051] Referring to FIG. 4, an embodiment of the present disclosure further provides a communication method. Optionally, the method can be applied to an AP MLD. This method can include the following steps 401 to 402.

[0052] In step 401, determine a target wireless frame, based on the change amount of the value of the maximum simultaneous link number field, add the number of Link Info domains in the Basic ML information element, and based on the attached AP corresponding to the added Link Info field, determine the content in the Link Info field.

[0053] Here, the Basic ML information element is included in the target wireless frame, 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.

[0054] Here, based on the difference between the current value of the maximum simultaneous link number field (Maximum Number Of Simultaneous Links) and the value before the AP MLD adds an attached AP, add the number of Link Info fields in the Basic ML information element. For example, if the Maximum Number Of Simultaneous Links set before the AP MLD adds an attached AP is 4, and the Maximum Number Of Simultaneous Links set after the addition is 6, it is necessary to add two Link Info Fields in the Basic ML information element.

[0055] In step 402, transmit the target wireless frame.

[0056] Here, the target wireless frame includes a beacon frame or a probe response frame, and the AP MLD can broadcast the target wireless frame to identify whether it has added a new attached AP or deleted an existing attached AP.

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

[0060] 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, the Basic ML element includes an identification bit to indicate that the number of attached APs has changed.
