Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0043] The method and apparatus are based on the same disclosed concept. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and repeated parts will not be described again.

[0044] This disclosure provides a communication method applicable to a source device. See details below. Figure 1 , Figure 1 This is a flowchart illustrating a communication method provided in an embodiment of this disclosure.

[0045] Optionally, the method may include the following steps:

[0046] Step S11: Determine the first wireless frame, which includes the first address information associated with the first device.

[0047] In this embodiment of the disclosure, the first address information can be used to indicate the relevant addresses involved in the transmission of wireless frames based on the relay device.

[0048] The first device can be at least one of a source device, a relay device, or a destination device.

[0049] The first wireless frame includes communication data sent from the source device to the destination device. The first wireless frame is used to instruct the relay device to send a second wireless frame to the destination device. The communication data included in the second wireless frame is the same as the communication data included in the first wireless frame.

[0050] The first wireless frame includes a Media Access Control (MAC) header, and the MAC header of the first wireless frame includes first address information.

[0051] When the first device is attached to an MLD, the first address information includes the MAC address of the first device under the working connection or the MAC address of the MLD to which the first device is attached.

[0052] The first address information may include at least one of the following: address information associated with the source device, address information associated with the relay device, or address information associated with the destination device.

[0053] Step S12: Send the first wireless frame.

[0054] In this embodiment of the disclosure, after determining the first radio frame, the source device may send the first radio frame to the relay device.

[0055] When the source device is attached to an MLD, it sends the first radio frame to the relay device through its working connection; that is, it sends the first radio frame to the relay device through the working connection established between the attached MLD and the relay device. When the source device is not attached to an MLD, it can send the first radio frame through a direct communication connection established with the relay device.

[0056] In the communication method applied to the source device provided in the embodiments of this disclosure, the first address information includes at least one of the source address (SA), receiver address (RA), transmitter address (TA), and destination address (DA).

[0057] The SA includes a separate MAC address that identifies the MAC entity that initiated the data carried in the first radio frame.

[0058] The RA includes a separate MAC address that identifies the MAC entity that is the direct receiver of the data carried in the first radio frame.

[0059] The TA includes a separate MAC address that identifies the MAC entity that sends the first wireless frame to the shared wireless medium (WM).

[0060] The DA includes a separate MAC address that identifies the MAC entity that is the final recipient of the data carried in the first radio frame.

[0061] In the communication method applied to a source device provided in the embodiments of this disclosure, when the first address information includes SA, the first device is a source device.

[0062] That is, the SA in the first address information is associated with the source device and is used to indicate that the initiator of the data carried by the first radio frame is the source device.

[0063] When the source device is attached to an MLD, the SA included in the first address information is the MAC address of the MLD to which the source device is attached; when the source device is not attached to an MLD, the SA included in the first address information is the MAC address of the source device.

[0064] In the communication method applied to a source device provided in the embodiments of this disclosure, when the first address information includes TA, the first device is a source device.

[0065] That is, the TA included in the first address information is associated with the source device and is used to instruct the source device to send the first radio frame to the relay device.

[0066] When the source device is attached to an MLD, the TA included in the first address information is the MAC address of the source device under the working connection, that is, the MAC address under the working connection corresponding to when the source device sends the first radio frame. When the source device is not attached to an MLD, the TA included in the first address information is the MAC address of the source device.

[0067] In the communication method applied to the source device provided in the embodiments of this disclosure, when the first address information includes RA, the first device is a relay device.

[0068] That is, the RA included in the first address information is associated with the relay device and is used to indicate that the relay device is the direct receiver of the data carried by the first radio frame.

[0069] When the relay device is attached to an MLD, the RA included in the first address information is the MAC address of the relay device under the working connection, that is, the MAC address of the relay device under the working connection when receiving the first radio frame. When the relay device is not attached to an MLD, the RA included in the first address information is the MAC address of the relay device.

[0070] In the communication method applied to the source device provided in the embodiments of this disclosure, when the first address information includes DA, the first device is the destination device.

[0071] That is, the DA included in the first address information is associated with the destination device and is used to indicate that the destination device is the final recipient of the data carried by the first radio frame.

[0072] When the destination device is attached to an MLD, the first address information includes the DA, which is the MAC address of the MLD to which the destination device is attached. When the destination device is not attached to an MLD, the first address information includes the DA, which is the MAC address of the destination device.

[0073] In the communication method applied to the source device provided in the embodiments of this disclosure, the source device, the relay device and the destination device can all be attached to a multi-link device (MLD), wherein the MLD can be represented as APMLD and Non-AP MLD, respectively.

[0074] As a first example, see Figure 2 AP MLD can represent an access point device that supports multiple connection communication functions, while non-AP MLD can represent a site device that supports multiple connection communication functions.

[0075] Reference Figure 2 An AP MLD can include three auxiliary AP devices, such as Figure 2 The diagram shows AP1, AP2, and AP3; each AP device can operate in Connection 1, Connection 2, and Connection 3 respectively; a non-AP MLD can also include three auxiliary STA devices, such as... Figure 2 The diagram shows STA1, STA2, and STA3; STA1 operates at connection 1, STA2 operates at connection 2, and STA3 operates at connection 3. Figure 2In the example, assume AP1 communicates with STA1 via the corresponding first connection, Link 1; similarly, AP2 communicates with STA2 via the corresponding second connection, Link 2; and the AP device communicates with STA3 via the third connection, Link 3. Furthermore, Links 1 to 3 can be multiple connections at different frequencies, such as connections at 2.4GHz, 5GHz, and 6GHz, or several connections with the same or different bandwidths at 2.4GHz. Additionally, multiple channels can exist under each connection. It is understood that... Figure 2 The communication scenarios shown are merely exemplary, and the present disclosure is not limited thereto. For example, the AP MLD can be connected to multiple (three) non-AP MLDs, or under each connection, the AP device can communicate with multiple other types of site devices.

[0076] In this embodiment of the disclosure, at least one of the source device, relay device, and destination device can be an AP device attached to the AP MLD, or a STA attached to a non-AP MLD.

[0077] An AP device can be a wireless switch for a wireless network, or an access device for a wireless network. An AP device may include software applications and / or circuitry to enable other types of nodes in the wireless network to communicate with the outside and inside of the wireless network. As an example, an AP device may be a terminal device or network device equipped with a Wi-Fi chip.

[0078] Specifically, STA devices may include, but are not limited to: cellular phones, smartphones, wearable devices, computers, personal digital assistants (PDAs), personal communication system (PCS) devices, personal information managers (PIMs), personal navigation devices (PNDs), global positioning systems, multimedia devices, and Internet of Things (IoT) devices.
