[0002] To achieve higher throughput, lower network latency, and higher reliability, a Multi-Link Operation (MLO) mechanism has been introduced in Wi-Fi technology. Devices that support the MLO function are called Multi-Link Devices (MLDs). With the help of MLO technology, multiple connections can be established across frequency bands between Multi-Link Access Point Devices (AP MLDs) and Multi-Link Station Devices (Non-AP MLDs). MLO can not only effectively improve system throughput but also reduce network latency, reduce packet loss rate, and improve communication reliability by preferentially selecting links or dynamically switching links.

[0003] In the MLO mechanism, after the AP MLD and the Non-AP MLD negotiate and successfully establish multiple connections, multi-connection reconfiguration can also be performed between them; therefore, a way to support multi-connection reconfiguration needs to be provided to improve the MLO mechanism.

[0030] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, not all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0031] The embodiments of the present disclosure provide a communication method, an electronic device, and a storage medium for providing a way to support multi-connection reconfiguration.

[0032] Among them, the method and the device are based on the same inventive concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repeated parts will not be described again.

[0033] As Figure 1 shown, the embodiments of the present disclosure provide a communication method. Optionally, the method can be applied to a multi-connection station device Non-AP MLD; optionally, in the embodiments of the present disclosure, a multi-connection station device is, for example, an electronic device with a wireless network access function, providing a Frame Delivery service to enable information to be transmitted; a multi-connection access point device is, for example, a device with a wireless-to-wired bridging function, and the multi-connection access point device is responsible for extending the services provided by the wired network to the wireless network.

[0034] The method may include the following steps:

[0035] Step 101, determining a first wireless frame; wherein, the first wireless frame includes first identification information, and the first identification information indicates whether the first wireless frame is used to request multi-connection reconfiguration for a multi-connected station device Non-AP MLD.

[0036] In a wireless local area network, a basic service set (BSS) can be composed of an AP and one or more stations (STA) communicating with the AP. A basic service set can be connected to a distribution system (DS) through its AP, and then access another basic service set to form an extended service set (ESS). As a first example, refer to Figure 2 , AP1 and STA1 form BSS1, and AP2 and STA2 form BSS2; if the coverage areas of two or more BSSs overlap, an overlapping basic service set (OBSS) is formed, such as Figure 2 in which BSS1 and BSS2 overlap to form an OBSS.

[0037] Optionally, in the embodiments of the present disclosure, the AP and the STA may be devices supporting multi-connection. For example, they may be respectively represented as AP MLD and Non-AP MLD; AP MLD may represent an access point supporting multi-connection communication functions, and Non-AP MLD may represent a station supporting multi-connection communication functions.

[0038] Referring to Figure 3 , AP MLD may include three affiliated APs, such as Figure 3 AP1, AP2, and AP3 shown; each AP may work on connection 1, connection 2, and connection 3 respectively; Non-AP MLD may also include three affiliated STAs, such as Figure 2 STA1, STA2, and STA3 shown; STA1 works on connection 1, STA2 works on connection 2, and STA3 works on connection 3.

[0039] For the sake of convenience of description, hereinafter, an example of communication between one AP and one STA under multi-connection will be mainly described. However, the exemplary embodiments of the present disclosure are not limited thereto. In Figure 3In the example, it is assumed that AP1 communicates with STA1 through the corresponding first connection Link 1. Similarly, AP2 communicates with STA2 through the corresponding second connection Link 2, and AP communicates with STA3 through the third connection Link 3. In addition, Link 1 to Link 3 can be multiple connections at different frequencies respectively. For example, connections at 2.4 GHz, 5 GHz, 6 GHz, or several connections with the same or different bandwidths at 2.4 GHz. In addition, there can be multiple channels under each connection. It can be understood that Figure 2 the communication scenario shown is only exemplary, and the present disclosure concept is not limited thereto. For example, AP MLD can be connected to multiple (three) Non-AP MLDs, or under each connection, AP can communicate with multiple other types of stations.

[0040] Generally, the multi-connection between Non-AP MLD and AP MLD is established through negotiation by exchanging (Re)AssociationRequest frame (or Re-association Request frame) and Association Response frame (or Re-association Response frame) between the two. For example, the number of connections established between the two and the basic attributes of each connection are negotiated through the above wireless frame carrying BasicMulti-Link element; the basic attributes are, for example, connection identifier (Link ID), MLD capability and operation (MLD Capability and Operation).

[0041] After successfully negotiating and establishing multiple connections between the Non-AP MLD and the AP MLD, connection reconfiguration can also be performed between the two. For example, the AP MLD can add or delete subordinate APs to add new connections or delete established connections. For example, the AP MLD indicates the addition of a new subordinate AP through the Basic Multi-Link element of the Beacon frame or Probe Response frame and through the Reduced Neighbor Report element. Or, the Non-AP MLD can add new connections or delete established connections. For example, taking the deletion of an established connection as an example, when the battery capacity of the Non-AP MLD is limited and the remaining power is low, the Non-AP MLD side may need to initiate the removal of some established connections to the AP MLD to reduce its own energy consumption and avoid signal interruption caused by the exhaustion of energy. Therefore, the Non-AP MLD deletes the established connection. Or, after the Non-AP MLD and the AP MLD establish multiple connections, when the Non-AP MLD detects that the AP MLD needs to add a new subordinate AP, the Non-AP MLD side needs to add a subordinate STA through the re-association mechanism to establish a new connection. This method will cause the interruption of service transmission on the existing connection. Therefore, a method is needed to seamlessly add a new connection without affecting the established connection.

[0042] When the Non-AP MLD can add new connections or delete established connections, or in other scenarios, the Non-AP MLD determines a first wireless frame, and the first wireless frame includes first identification information, and the first identification information indicates whether the first wireless frame is used to request multi-connection reconfiguration for the multi-connection station device Non-AP MLD; optionally, the first wireless frame can be a multi-connection reconfiguration frame, which is used for multi-connection reconfiguration negotiation between the AP MLD and the Non-AP MLD after the establishment of multiple connections, and the first wireless frame includes a multi-connection reconfiguration request frame (ML Reconfiguration Request frame).

[0043] Step 102, send the first wireless frame.

[0044] The Non-AP MLD sends a first wireless frame. After receiving the first wireless frame, the AP MLD determines whether the first wireless frame is a request from the Non-AP MLD for multi-link reconfiguration according to the first identification information. The content of the multi-link reconfiguration may include, for example, the number of established connections and the basic attributes of each connection. The basic attributes may include, for example, the Link ID, MLD Capability and Operation, etc. In this way, when the Non-AP MLD adds a connection or deletes an established connection, multi-link reconfiguration can be achieved.

[0045] Embodiments of the present disclosure provide a communication method. Optionally, the method can be applied to a multi-link station device, i.e., the Non-AP MLD. The method includes:

[0056] Table 1:

[0057]

[0058] As shown in Table 1, the Multi-Link Control field includes a Reconfiguration Request identifier, and the Reconfiguration Request identifier indicates the category of the Multi-Link Reconfiguration frame of the Reconfiguration Multi-Link element. The category of the Multi-Link Reconfiguration frame is, for example, a multi-connection reconfiguration request or a multi-connection reconfiguration response.

[0059] Specifically, as shown in Table 1, a Reconfiguration Request identifier bit is added to bit B3 of the multi-connection control field in the Reconfiguration Multi-Link element. If the Reconfiguration Request bit is set to 1, it indicates that the Multi-Link Reconfiguration frame carrying the Reconfiguration Multi-Link element is a multi-connection configuration request;

[0060] If the Reconfiguration Request bit is set to 0, it indicates that the Multi-Link Reconfiguration frame carrying the Reconfiguration Multi-Link element is a multi-connection configuration response.

The first wireless frame includes a first Protected EHT Action information element; wherein, EHT represents Extremely High Throughput.

[0067] As a third example, the Multi-Link Reconfiguration frame can be an Action frame, as shown in Table 2 below:

[0069]

[0070] The first wireless frame includes, but is not limited to, the above information elements, fields or subfields: Category, Protected EHT Action, Dialog Token, Reconfiguration Multi-Link element.

[0071] Further, the first Protected EHT Action information element includes second identification information, and the second identification information indicates that the type of the first wireless frame is a multi-link reconfiguration frame. As a fourth example, the format of the first Protected EHT Action information element is as shown in Table 3 below:

[0072] Table 3:

[0073]

[0074] When the value of the first Protected EHT Action information element is 8, it indicates that the type of the first radio frame is a multi-connection reconfiguration frame.

[0082] Optionally, the Non-AP MLD determines the first radio frame and carries the first identification information, where the first identification information indicates whether the first radio frame is used to request multi-connection reconfiguration for the multi-connection station device Non-AP MLD; and the second identification information is carried through the first Protected EHT Action information element, and the type of the first radio frame is indicated as a multi-connection reconfiguration frame through the second identification information, so as to realize multi-connection reconfiguration when a new connection is added or an established connection is deleted in the Non-AP MLD.

[0085] Optionally, the second wireless frame includes a multi-connection reconfiguration response frame (ML ReconfigurationResponse frame);

[0086] After receiving the first wireless frame, the AP MLD determines, according to the first identification information, that the first wireless frame is a Non-AP MLD request for multi-connection reconfiguration, and then feeds back the second wireless frame to the Non-AP MLD to indicate whether the AP MLD accepts or rejects the request for multi-connection reconfiguration.

[0097] When the first wireless frame is used to request a multi-connection reconfiguration for the Non-AP MLD, for example, when the AP MLD receives the first wireless frame carrying the Reconfiguration Multi-Link element and the ReconfigurationRequest position therein is 1, the Dialog Token in the second wireless frame should be the same as the Dialog Token in the first wireless frame to indicate that the second wireless frame is used to respond to the first wireless frame.

[0114] Optionally, the third identification information is carried in the second multi-connection reconfiguration Reconfiguration Multi-Link information element of the second wireless frame;

[0118] Optionally, the second Reconfiguration Multi-Link information element includes Status Code information, and the Status Code information indicates whether the AP MLD accepts a request for multi-link reconfiguration for the Non-AP MLD;

[0119] Optionally, the Status Code information is carried in the STA information field in each STA profile corresponding to the connection identifier carried in the first radio frame;

[0120] Optionally, the second radio frame includes a multi-link reconfiguration response frame.

[0121] Wherein, when the AP MLD receives the first radio frame, and the first radio frame is used to request multi-link reconfiguration for the Non-AP MLD, the AP MLD sends a second radio frame to respond to the first radio frame, and indicates whether the second radio frame is used to respond to the request for multi-link reconfiguration through the third identification information; the Non-AP MLD determines whether the AP MLD accepts the multi-link configuration request according to the second radio frame.

[0122] In the embodiments of the present disclosure, the Non-AP MLD determines the first radio frame; wherein, the first radio frame includes first identification information, and the first identification information indicates whether the first radio frame is used to request multi-link reconfiguration for the multi-link station device Non-AP MLD; in this way, when the Non-AP MLD adds a connection or deletes an established connection, multi-link reconfiguration can be realized.

[0123] The embodiments of the present disclosure provide a multi-link reconfiguration method to improve the MLO mechanism.

[0124] See Figure 4 , the embodiments of the present disclosure provide a communication method. Optionally, the method can be applied to a multi-link access point device AP MLD, and the method may include the following steps:

[0125] Step 401, receive a first radio frame; wherein, the first radio frame includes first identification information, and the first identification information is used to indicate whether the first radio frame is used to request multi-link reconfiguration for the multi-link station device Non-AP MLD.

[0126] Wherein, the architecture of the WLAN to which the communication method provided in the embodiments of the present disclosure is applied refers to the foregoing first example, and details are not described herein again.

[0127] Under normal circumstances, the multi-link between Non-AP MLD and AP MLD is established through negotiation by exchanging (Re)AssociationRequest frame (or Re-association Request frame) and Association Response frame (or Re-association Response frame) between the two. For example, the BasicMulti-Link element is carried by the above wireless frame to negotiate the number of connections established between the two and the basic attributes of each connection; the basic attributes are, for example, the connection identifier (Link ID), MLD capability and operation (MLD Capability and Operation).

[0128] After negotiating and successfully establishing a multi-link between Non-AP MLD and AP MLD, connection reconfiguration can also be performed between the two; for example, AP MLD can add or delete subordinate APs to add new connections or delete established connections. For example, APMLD indicates the addition of a new subordinate AP through the Basic Multi-Link element of the beacon frame (Beacon) or the probe response frame (Probe Response) and through the Reduced Neighbor Report element. Or, Non-AP MLD can add new connections or delete established connections; for example, taking the deletion of an established connection as an example, when the battery capacity of the Non-AP MLD side is limited and the remaining power is low, the Non-AP MLD side may need to initiate the removal of some established connections to the AP MLD to reduce its own energy consumption and avoid signal interruption caused by exhaustion of energy; therefore, the Non-AP MLD deletes the established connection. Or, after the Non-AP MLD and APMLD establish a multi-link, when the Non-AP MLD detects that the AP MLD needs to add a new subordinate AP, the Non-AP MLD side needs to add a subordinate STA through the re-association mechanism to establish a new connection. This method will cause the interruption of service transmission on the existing connection, so a method is needed to achieve seamless access and addition of new connections without affecting the established connections.

[0129] When a new connection can be added or an established connection can be deleted by a Non-AP MLD, or in other scenarios, the Non-AP MLD determines a first wireless frame, and the first wireless frame includes first identification information, where the first identification information indicates whether the first wireless frame is used to request multi-link reconfiguration for the multi-link station device Non-AP MLD; optionally, the first wireless frame can be a type of multi-link reconfiguration frame, which is used for multi-link reconfiguration negotiation between an AP MLD and a Non-AP MLD after multi-link establishment, and the first wireless frame includes a multi-link reconfiguration request frame (ML Reconfiguration Request frame).

[0130] The Non-AP MLD sends the first wireless frame. After receiving the first wireless frame, the AP MLD determines whether the first wireless frame is a request from the Non-AP MLD for multi-link reconfiguration according to the first identification information; the content of the multi-link reconfiguration is, for example, the number of established connections and the basic attributes of each connection; the basic attributes are, for example, the link ID, MLD capability and operation, etc. In this way, multi-link reconfiguration can be achieved when the Non-AP MLD adds a new connection or deletes an established connection.
