[0099] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0100] As shown in FIG1 , a communication system 100 includes a non-access point (Non-AP) device 101 and an access point (AP) device 102 .

[0101] In some embodiments, the non-access point device 101 includes, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports WiFi communication. Optionally, the wireless communication terminal includes, but is not limited to, at least one of a mobile phone, a wearable device, an Internet of Things device that supports WiFi communication, a car with WiFi communication, a smart car, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device used in industrial control, a wireless terminal device used in self-driving, a wireless terminal device used in remote medical surgery, a wireless terminal device used in a smart grid, a wireless terminal device used in transportation safety, a wireless terminal device used in a smart city, and a wireless terminal device used in a smart home.

[0102] Specifically, the non-access point device 101 may be a terminal device or a network device with a wireless fidelity (WiFi) chip. Optionally, the non-access point device 101 may support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, and 802.11bn, as well as the next generation 802.11 protocol, but is not limited thereto.

[0103] In some embodiments, the access point device 102 can be an access point for a mobile terminal to enter a wired network. The AP is equivalent to a bridge connecting a wired network and a wireless network. Its main function is to connect various wireless network clients together and then connect the wireless network to the Ethernet. Specifically, the AP can be a terminal device or a network device with a wireless fidelity chip. Optionally, the AP can support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b and 802.11a, 802.11bf, 802.11bn, and support the next generation 802.11 protocol, but is not limited to this.

[0104] In the embodiments of the present disclosure, non-access point device 101 and access point device 102 may be devices that support multi-link communication. For example, access point device 102 may be represented as an Access Point Multi-Link Device (AP MLD), and non-access point device 101 may be represented as a Non-Access Point Multi-Link Device (Non-AP MLD). That is, an AP MLD may represent an access point that supports multi-link communication capabilities, and a Non-AP MLD may represent a station that supports multi-link communication capabilities. For example, referring to FIG1 , Non-AP MLD 101 and AP MLD 102 may communicate via multiple links.

[0105] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0106] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0107] FIG2 is a schematic diagram illustrating interactions in a method for multi-link communication according to an embodiment of the present disclosure. In FIG2 , the first device may be one of Non-AP MLD 101 and AP MLD 102, and the second device may be the other of Non-AP MLD 101 and AP MLD 102. As shown in FIG2 , the method includes steps 210 to 250.

[0108] In step 210 , the first device may determine a first radio frame.

[0109] As a non-limiting embodiment, the first radio frame may include at least one first identification information. The at least one first identification information is used to identify that the first radio frame includes communication information of the first communication technology used by the first device in at least one link among the multiple links. According to an embodiment of the present disclosure, the multiple links are established between the first device and the second device. According to an embodiment of the present disclosure, the first communication technology is at least one wireless communication technology other than Wireless Fidelity (Wi-Fi) (for example, but not limited to, BT, NR, or UWB).

[0110] In step 220, the first device may send a first radio frame to the second device. Specifically, the first device may send the first radio frame to the second device over a first link among multiple links. The first link in step 220 may be one of the at least one link in step 210, or may be another link different from the at least one link in step 210.

[0111] In an embodiment of the present disclosure, the first device can transmit communication information of the first communication technology over one or more links (at least one link in step 210) over one link (e.g., the first link in step 220). Therefore, in the UHR, the anti-interference wireless communication mechanism for multi-link communication is met, thereby improving throughput.

[0112] According to an embodiment of the present disclosure, when the first device is the Non-AP MLD 101, the first wireless frame in steps 210 and 220 may be an Association Request frame, a Re-association Request frame, a Probe Request frame, or a Multi-Link Probing Request (ML probing Request) frame, but the present disclosure is not limited thereto.

[0113] According to an embodiment of the present disclosure, when the first device is the AP MLD 102, the first wireless frame in steps 210 and 220 may be a beacon frame, an association response frame, a re-association response frame, a probe response frame, or a multi-link probe response (ML probing Response) frame, but the present disclosure is not limited thereto.

[0114] As a non-limiting example, the communication information of the first communication technology may include at least one of the following:

[0115] start time information of the first communication technology;

[0116] End time information of the first communication technology;

[0117] duty cycle information of the first communication technology;

[0118] Communication time interval information of the first communication technology.

[0119] According to an embodiment of the present disclosure, the first identification information and the communication information of the first communication technology may be included in different fields of the first radio frame.

[0120] As a non-limiting example, the first radio frame may include a multilink information element. According to an embodiment of the present disclosure, the multilink information element may include link identification information and a site characteristic field corresponding to at least one link in step 210, wherein each first identification information in the at least one first identification information identifies that communication information of the first communication technology is included in the site characteristic field corresponding to the first identification information in the multilink information element.

[0121] For example, Table 1 below shows an exemplary format of a multi-connection information element.

[0122] Table 1. Multi-Link Element

[0123] According to an embodiment of the present disclosure, a multi-link information element may include a site characteristic sub-element field (e.g., a Per-STA Profile subelement) corresponding to each of the multiple links. For example, the link information (Link Info) of the multi-link information element may include a site characteristic sub-element field. The number of site characteristic sub-element fields is the same as the number of the multiple links.

[0124] For example, if the first device is a Non-AP MLD 101 and includes three links (it can be considered that the first device includes three affiliated Non-AP STAs), the Multi-Link Information Element can include three Site Characteristics sub-element fields corresponding to the three links respectively. For example, if the first device is an AP MLD 101 and includes three links (it can be considered that the first device includes three affiliated AP STAs), the Multi-Link Information Element can include three Site Characteristics sub-element fields corresponding to the three links respectively.

[0125] For example, Table 2 below shows an exemplary format of the site characteristics sub-element field (eg, Per-STA Profile subelement) in the link information (Link Info) of the multi-link information element.

[0126] Table 2. Per-STA Profile subelement

[0127] According to an embodiment of the present disclosure, the first identification information and the communication information of the first communication technology may be included in different fields of the first radio frame. For example, in the STA Control field of Table 2, the link identification information (e.g., Link ID) of the corresponding link and the first identification information may be included. That is, each first identification information may correspond to a link identification information (e.g., Link ID) to identify that the communication information of the first communication technology under the link identified by the link identification information exists in the first radio frame. For example, in the STA Profile field of Table 2, the communication information of the first communication technology under the link identified by the link identification information may be included, such as start time information, end time information, duty cycle information, and / or the time interval (Communication Interval, CI) between two communications. For example, the start time information may be based on the Time Sync Function (TSF) parameter under the corresponding link. In other words, the second device that receives the first radio frame can first parse the link identification information and the first identification information in the STA Control field of Table 2 to determine that communication information using the first communication technology exists under the link identified by the link identification information in the STA feature field, and then obtain the communication information using the first communication technology under the corresponding link by parsing the STA feature field. Therefore, it can be ensured that the communication information using the first communication technology of the first radio frame is correctly parsed.

[0128] According to an embodiment of the present disclosure, the first communication technology is at least one wireless communication technology other than Wireless Fidelity (Wi-Fi) (for example, but not limited to, BT, NR, or UWB). As a non-limiting example, the type of the first communication technology (for example, but not limited to, BT, NR, or UWB) included in the STA Features field of Table 2 can be defined by defining the value of the Subelement ID field in Table 2.

[0129] According to an embodiment of the present disclosure, a first radio frame of a first device may include communication information of each type of first communication technology in the first communication technology corresponding to each link of at least one of the multiple links. For example, the communication information of each type of first communication technology may include at least one of start time information (wherein the start time information is based on the TFS of the response link) of the first communication technology of the corresponding link, end time information, duty cycle information, and communication time interval information of the first communication technology of the type. However, the present disclosure is not limited to this. For example, the communication information may include duration information of the first communication technology of the type. In addition, the communication information of different types of first communication technologies under the corresponding links may be different.

[0130] Assuming that BT technology is used in the first link and the second link of the multiple links of the first device, the site feature sub-element field (for example, the link information (Link Info) in Table 1) may include two Per-STA Profile subelements corresponding to the first link and the second link, respectively, wherein, in the Per-STA Profile subelemen corresponding to the first link, the Subelement ID may be set to identify the first communication technology as a BT type, the STA Control includes the link identification information of the first link (for example, Link ID 1) and the first identification information, and the STA Profile includes communication information for communication using BT under the first link, wherein the communication information may include at least one of BT start time information (for example, the start time information may be based on the TSF of the first link as a reference point), end time information, duty cycle information, and communication time interval information, however, the present disclosure is not limited thereto. For example, the communication information may include BT duration information, etc.; in the Per-STA Profile subelemen corresponding to the second link, the Subelement ID may be set to identify the first communication technology as an NR type, the STA Control includes the link identification information of the second link (for example, Link ID 2) and the first identification information, and the STA The profile includes communication information for communication using BT under the second link, wherein the communication information may include at least one of the start time information of NR (for example, the start time information may be based on the TSF of the second link as a reference point), the end time information, the duty cycle information, and the communication time interval information. However, the present disclosure is not limited to this. For example, the communication information may include the duration information of NR, etc.

[0131] Assuming that BT and NR technologies are used in the first link of multiple links of the first device, the site feature sub-element field (for example, the link information (Link Info) of Table 1) may include a Per-STA Profile subelement corresponding to the first link, wherein the Per-STA Profile subelemen may include information corresponding to BT and NR, respectively. For example, STA Control may include link identification information (for example, Link ID 1) of the first link and the first identification information. However, for BT, Subelement ID 1 and STA Profile 1 may exist, Subelement ID 1 may be set to identify the first communication technology as a BT type, and STA Profile 1 includes communication information for communication using BT under the first link; for NR, Subelement ID 2 and STA Profile 2 may exist, Subelement ID 2 may be set to identify the first communication technology as an NR type, and STA Profile 2 includes communication information for communication using NR under the first link. However, this is merely exemplary and the present disclosure is not limited thereto.

[0132] As a non-limiting embodiment, the first wireless frame may also include at least one second identification information, each second identification information identifying that: in the first device, the communication information of the first communication technology under the link corresponding to the second identification information is the same as the communication information of the first communication technology under at least one link other than the link in the multiple links.

[0133] According to embodiments of the present disclosure, there may be situations where the first communication technology and corresponding communication information under two or more links are consistent. In this case, an inheritance mechanism can be used to identify which links are consistent. For example, for UWB communication, its designed bandwidth is very wide and may cover multiple link bandwidths. Therefore, the communication information under these links can be set to be consistent.

[0134] For example, the second identification information may be included in the STA Control field of Table 2. For example, if the communication information of the first communication technology under the first link to the third link of the first device is the same, three Per-STA Profile subelement (Table 2) corresponding to the first link to the third link respectively may be included in the Link Info (Table 1) of the multi-connection information element of the first radio frame, and the second identification information may be included in the STA Control (Table 2) of each Per-STA Profile subelement, wherein the second identification information in the STA Control of the Per-STA Profile subelement corresponding to the first link, the second identification information in the STA Control of the Per-STA Profile subelement corresponding to the second link, and the second identification information in the STA Control of the Per-STA Profile subelement corresponding to the third link may be set to the same value to identify that the communication information of the first communication technology under the first link to the third link is the same.

[0135] According to an embodiment of the present disclosure, there may be two links that are one of a non-simultaneously TX and RX (NSTR) link, an enhanced multi-link single radio (eMLSR) link, or an enhanced multi-link multi-radio (eMLMR) link. If a first communication technology exists under one of the two links, and the first communication technology does not exist under the other of the two links, then the other link can inherit the communication information of the first communication technology under the one link, that is, the communication information of the first communication technology under the other link is the same as the communication information of the first communication technology under the one link by default.

[0136] As a non-limiting embodiment, the first wireless frame may further include a capability information identification bit, and the capability information identification bit is used to identify: the capability information value that the first device supports sending communication information of the first communication technology. For example, the first wireless frame may include an extended capabilities information element or a UHR capability information element, and the capability information identification bit may be included in the extended capabilities information element or the UHR capability information element. When the second device receives the first wireless frame, it may first parse out the capability information identification bit to determine that the first wireless frame includes communication information of the first communication technology, and may further parse the information in Table 1 to Table 2 to obtain the communication information of the first communication technology. Therefore, it can be ensured that the first wireless frame is correctly transmitted and parsed.

[0137] As a non-limiting embodiment, although not shown in FIG2 , the method shown in FIG2 may further include: before sending the communication information of the first communication technology via the first radio frame, sending a fifth radio frame, wherein the fifth radio frame may include a capability information identification bit, and the capability information identification bit is used to identify: the capability information value that the first device supports sending the communication information of the first communication technology. That is, unlike the above embodiment, the capability information identification bit and the first identification information and the corresponding communication information of the first communication technology may be included in different frames and sent, and the capability information identification bit is included and sent before the first identification information and the corresponding communication information of the first communication technology. For example, in the case where the first device is an AP MLD, the fifth radio frame may be a beacon frame. For example, the first device may broadcast the beacon frame so that the second device can be informed of the capabilities of the first device.

[0138] Referring back to FIG. 2 , in step 230 , the first device may receive a second radio frame from the second device, where the second radio frame may include at least one piece of third identification information. According to an embodiment of the present disclosure, the at least one piece of third identification information indicates that the second radio frame includes communication information of a first communication technology used by the second device in at least one of the multiple links.

[0139] According to an embodiment of the present disclosure, when the second device is the AP MLD 102, the second wireless frame in step 230 may be a beacon frame, an association response frame, a re-association response frame, a probe response frame, or a multi-link probe response (ML probing Response) frame, but the present disclosure is not limited thereto.

[0140] According to an embodiment of the present disclosure, when the second device is the Non-AP MLD 101, the second wireless frame in step 230 may be an Association Request frame, a Re-association Request frame, a Probe Request frame, or a Multi-Link Probing Request frame, but the present disclosure is not limited thereto.

[0141] In an embodiment of the present disclosure, the first communication technology is at least one wireless communication technology other than Wireless Fidelity (Wi-Fi) (for example, but not limited to, BT, NR, or UWB).

[0142] As a non-limiting example, the communication information of the first communication technology may include at least one of the following:

[0143] start time information of the first communication technology;

[0144] End time information of the first communication technology;

[0145] duty cycle information of the first communication technology;

[0146] Communication time interval information of the first communication technology.

[0147] As a non-limiting embodiment, the second wireless frame may also include at least one fourth identification information, each fourth identification information identifying: in the second device, the communication information of the first communication technology under the link corresponding to the fourth identification information is the same as the communication information of the first communication technology under at least one link other than the link in the multiple links.

[0148] As a non-limiting embodiment, the second radio frame may further include a capability information identification bit, which is used to identify: a capability information value that the second device supports sending communication information of the first communication technology. For example, the second radio frame may include an extended capabilities information element or a UHR capabilities information element, and the capability information identification bit may be included in the extended capabilities information element or the UHR capabilities information element.

[0149] As a non-limiting embodiment, although not shown in FIG2 , the method shown in FIG2 may further include: before sending the communication information of the first communication technology via the second radio frame, sending another radio frame, wherein the another radio frame may include a capability information identification bit, and the capability information identification bit is used to identify: the capability information value of the second device supporting the sending of the communication information of the first communication technology. That is, unlike the above embodiment, the capability information identification bit and the fourth identification information and the corresponding communication information of the first communication technology may be included in different frames and sent, and the capability information identification bit is sent before the fourth identification information and the corresponding communication information of the first communication technology.

[0150] According to an embodiment of the present disclosure, the second radio frame may include a multilink information element. Similar to the first identification information described with reference to Tables 1 and 2, the third identification information may be included in the multilink information element of the second radio frame in a similar manner. For the sake of brevity, repeated descriptions are omitted here. Similar to the second identification information described with reference to Tables 1 and 2, the fourth identification information may be included in the multilink information element of the second radio frame in a similar manner. For the sake of brevity, repeated descriptions are omitted here.

[0151] Referring back to Figure 2, in step 240, the first device sends a third wireless frame to the second device, wherein the third wireless frame includes at least one fifth identification information, and each fifth identification information identifies that: the communication information of the first communication technology under the link corresponding to the fifth identification information in the first device has changed.

[0152] For example, each fifth identification information may be included in the STA Control (Table 2) of the corresponding per-STA profile subelement of the third radio frame (for example, but not limited to, the basic service set parameter change count (BSS parameter change count) field in the STA Control field); and the communication information of the first communication technology that is specifically sent to change may be included in the STA Profile (Table 2) of the per-STA profile subelement. It will be understood that the third radio frame may not include all fields of the multilink information element shown in Table 1, but only include fields associated with changes in the communication information of the first communication technology, thereby reducing the amount of transmitted data and improving communication efficiency.

[0153] When the first device is an AP MLD, the first device (AP MLD) may proactively send a third radio frame to the second device (non-AP MLD) indicating a change in communication information of the first communication technology. For example, but not limited to, the third radio frame may be a beacon frame, an unsolicited probe response frame, or a newly defined report frame sent by the first device (AP MLD). However, the present disclosure is not limited thereto, and the first device (AP MLD) may send the third radio frame upon receiving a query frame from the second device (non-AP MLD).

[0154] When the first device is a non-AP MLD, the first device (non-AP MLD) may proactively send a third radio frame to the second device (AP MLD) indicating a change in communication information of the first communication technology. For example, but not limited to, the third radio frame may be a newly defined report frame (e.g., a co-located interference report frame). However, the present disclosure is not limited thereto. The first device (AP MLD) may send the third radio frame upon receiving an inquiry frame from the second device (AP MLD).

[0155] Continuing with Figure 2, in step 250, the first device may receive a fourth radio frame from the second device, where the fourth radio frame includes at least one sixth identification information. In other words, the second device may send the fourth radio frame including at least one sixth identification information to the first device. According to an embodiment of the present disclosure, each sixth identification information indicates that communication information of the first communication technology under the link corresponding to the sixth identification information has changed in the second device.

[0156] For example, each sixth identification information may be included in the STA Control (Table 2) of the corresponding per-STA profile subelement of the fourth radio frame (for example, but not limited to, the basic service set parameter change count (BSS parameter change count) field in the STA Control field); and the communication information of the first communication technology that is specifically sent to change may be included in the STA Profile (Table 2) of the per-STA profile subelement. It will be understood that the fourth radio frame may not include all fields of the multilink information element shown in Table 1, but only include fields associated with changes in the communication information of the first communication technology, thereby reducing the amount of transmitted data and improving communication efficiency.

[0157] When the second device is an AP MLD, the second device (AP MLD) may proactively send a fourth radio frame to the first device (non-AP MLD) indicating a change in communication information of the first communication technology. For example, but not limited to, the fourth radio frame may be a beacon frame, an unsolicited probe response frame, or a newly defined report frame sent by the second device (AP MLD). However, the present disclosure is not limited thereto, and the second device (AP MLD) may send a third radio frame upon receiving a query frame from the first device (non-AP MLD).

[0158] If the second device is a non-AP MLD, the second device (non-AP MLD) may proactively send a fourth radio frame to the first device (AP MLD) indicating a change in communication information of the first communication technology. For example, but not limited to, the fourth radio frame may be a newly defined report frame (e.g., a co-located interference report frame). However, the present disclosure is not limited thereto. The second device (AP MLD) may send a third radio frame upon receiving an inquiry frame from the first device (AP MLD).

[0167] Figure 3 is a schematic diagram illustrating interactions of a method for multi-link communication according to an embodiment of the present disclosure. In Figure 3 , the first device may be an AP MLD, and the second device may be a Non-AP MLD.

[0168] 3 , in step 310, the AP MLD may send a beacon frame to the Non-AP MLD. For example, but not limited to, the AP MLD may broadcast the beacon frame. According to an embodiment of the present disclosure, the beacon frame may include at least one first identification information. The at least one first identification information is used to identify that the beacon frame includes communication information of the first communication technology used by the AP MLD in at least one link among the multiple links. According to an embodiment of the present disclosure, the multiple links are established between the first device and the second device. According to an embodiment of the present disclosure, the first communication technology is at least one wireless communication technology other than Wireless Fidelity (Wi-Fi) (for example, but not limited to, BT, NR, or UWB).

[0175] As a non-limiting embodiment, the beacon frame may also include at least one second identification information, each second identification information identifying: in the AP MLD, the communication information of the first communication technology under the link corresponding to the second identification information is the same as the communication information of the first communication technology under at least one link other than the link in the multiple links.

[0176] As a non-limiting embodiment, the beacon frame may further include a capability information identification bit, where the capability information identification bit is used to identify a capability information value indicating that the AP MLD supports sending communication information of the first communication technology.

[0177] According to an embodiment of the present disclosure, the first identification information, the second identification information, the communication information of the first communication technology, the multi-link information element, the link identification information, the site feature field, and the capability information identification bit can be similar to the various embodiments described with reference to Figure 2 and Tables 1 and 2. For the sake of simplicity, repeated descriptions are omitted here.

[0178] Continuing with FIG3 , in step 320, the AP MLD may receive one of an association request frame, a reassociation request frame, or a multi-link establishment request frame from the non-AP MLD. The frame received by the AP MLD from the non-AP MLD may include at least one third identification information. According to an embodiment of the present disclosure, the at least one third identification information indicates that the frame includes communication information of the first communication technology used by the non-AP MLD in at least one of the multiple links.

[0179] As a non-limiting example, the communication information of the first communication technology may include at least one of the following:

[0180] start time information of the first communication technology;

[0181] End time information of the first communication technology;

For the sake of simplicity, repeated descriptions are omitted here.

[0187] In step 330, the AP MLD may send one of an association response frame, a reassociation response frame, or a multi-link establishment response frame to the non-AP MLD. For example, the AP MLD may not include the first identification information, the communication information of the first communication technology, and the second identification information in the beacon frame in step 310, but may include such information in the frame in step 330.

[0188] The embodiment described with reference to FIG3 may be a process of establishing multiple connections between an AP MLD and a non-AP MLD. During the multi-link establishment process, the AP MLD and the non-AP MLD may carry information regarding periodic communications of other wireless communication technologies (i.e., the first communication technology described above). Specifically, the periodic communication information regarding other wireless communication technologies for each link may be carried in a multi-link information element (e.g., a basic multi-link information element), for example, in the Link Info field, as shown in Table 1.

[0189] For example, a bit in the STA control field can be used to identify the communication information (also called communication time information) of other communication technologies contained in the STA profile subelement field under the link corresponding to the link identification information (Link ID). Specifically, the communication information may include: start time, end time, where the start time is based on the TSF parameters under this link. In addition, the communication information may also include duty cycle information or the time interval (CI) between two communications, etc.

[0190] For example, there may be a situation where communication information is consistent under multiple links (for example, there may be UWB communication, which has a very wide designed bandwidth and may cover multiple link bandwidths). In this case, an inheritance mechanism can be used to identify which links are consistent (for example, the second identification information and the fourth identification information mentioned above).

[0197] FIG. 7 is a flowchart illustrating that the Non-AP MLD reports a change in the communication information of the first communication technology to the AP MLD according to an inquiry of the AP MLD.

[0198] In step 710, the AP MLD may send a query frame to the Non-AP MLD (eg, periodically), wherein the query frame is used to query whether a change in the communication information of the first communication technology occurs in the Non-AP MLD.

[0199] In step 720, the Non-AP MLD sends a report frame to the AP MLD in response to the inquiry frame. The report frame may be a newly defined report frame (e.g., a co-located interference report frame). If the Non-AP MLD is the first device, the report frame in step 720 may include at least one fifth identification information, each fifth identification information indicating that communication information of the first communication technology in the link corresponding to the fifth identification information in the first device (Non-AP MLD) has changed. If the Non-AP MLD is the second device, the report frame in step 720 may include at least one sixth identification information, each sixth identification information indicating that communication information of the first communication technology in the link corresponding to the sixth identification information in the second device (Non-AP MLD) has changed.

[0201] The method shown in FIG. 8 may be applied to a first device, which may be one of the Non-AP MLD 101 and the AP MLD 102 , and a second device may be the other of the Non-AP MLD 101 and the AP MLD 102 .

[0202] In step 810, the first device may determine a first radio frame. As a non-limiting embodiment, the first radio frame may include at least one first identification information. The at least one first identification information is used to identify that the first radio frame includes communication information of a first communication technology used by the first device in at least one link among a plurality of links. According to an embodiment of the present disclosure, the plurality of links are established between the first device and the second device. According to an embodiment of the present disclosure, the first communication technology is at least one of wireless communication technologies other than Wireless Fidelity (Wi-Fi) (for example, but not limited to, BT, NR, or UWB).

[0209] As a non-limiting embodiment, the first radio frame may further include a capability information identification bit, where the capability information identification bit is used to identify a capability information value indicating that the first device supports sending communication information using the first communication technology.

[0210] In step 820, the first device may send a first radio frame to the second device. Specifically, the first device may send the first radio frame to the second device over a first link among the multiple links. The first link in step 820 may be one of the at least one link in step 810, or may be another link different from the at least one link in step 810.

[0211] In step 830, the first device may receive a second radio frame from the second device, wherein the second radio frame may include at least one third identification information.
