[0083] Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0084] As shown in Figure 1, the communication system 100 includes a first device, a second device, and a third device; wherein, the first device and the second device can be an Access Point Multi-Link Device (AP MLD) or an Access Point Multi-Link Device (AP MLD), and the third device can be a site device (non-Access Point Multi-Link Device, non-AP MLD) or a multi-link site device (non-Access Point Multi-Link Device, non-AP MLD).

[0085] In some embodiments, the access point device can be an access point for mobile terminals to access a wired network. An AP acts as a bridge connecting wired and wireless networks, its main function being to connect various wireless network clients together and then connect the wireless network to the Ethernet. Specifically, an AP can be a terminal device or network device with a Wi-Fi chip. Optionally, the AP can support various 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 to these.

[0086] In some embodiments, the site equipment includes, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports Wi-Fi communication. Optionally, the wireless communication terminal may be at least one of, but is not limited to, a mobile phone, a wearable device, an IoT device that supports Wi-Fi communication, a car with Wi-Fi communication capabilities, 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 in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and a wireless terminal device in a smart home.

[0087] Specifically, the site equipment can be a terminal device or network device with a Wi-Fi chip. Optionally, the site equipment can 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 to these.

[0088] Optionally, in this embodiment of the disclosure, AP and STA can be devices that support multiple links. For example, they can be represented as Access Point Multi-Link Device (AP MLD) and Non-Access Point Multi-Link Device (non-AP MLD), respectively. AP MLD can represent an access point that supports multiple link communication functions, and non-AP MLD can represent a site that supports multiple link communication functions.

[0089] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0090] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0091] The embodiments disclosed herein can be applied to Wireless Local Area Networks (WLANs), such as LANs using the 802.11 series of protocols. In a WLAN, a Basic Service Set (BSS) is a fundamental component. An BSS network consists of site devices with some association within a specific coverage area. One type of association is where sites communicate directly with each other in a self-organizing network; this is called an Independent Basic Service Set (IBSS). Another more common scenario is that in a BSS network, there is only one central site dedicated to managing the BSS, called an Access Point (AP) device, while other sites in the BSS network that are not APs are called terminals, also known as non-AP STAs. APs and non-AP STAs are collectively referred to as STAs. When describing STAs, it is not necessary to distinguish between APs and non-AP STAs. Within the same BSS network, due to distance, transmission power, etc., a STA cannot detect other STAs that are far away; they are each other's hidden nodes.

[0092] Figure 2 is one of the interactive schematic diagrams of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, the method includes:

[0093] Step 201, the first device determines the first radio frame; wherein the first radio frame identifies the first NPCA main channel information of the first device and the second NPCA main channel information of the second device.

[0094] In WLANs, channels are typically divided into primary channels and non-primary channels (also known as auxiliary channels or secondary channels). To enhance network transmission reliability and increase throughput, the non-primary channel access (NPCA) mechanism was proposed. Channel access refers to the process by which nodes in the network acquire the right to use a channel. A non-primary channel can contain one or more sub-channels. For example, if the basic bandwidth unit is 20MHz, when the channel bandwidth is 20MHz, there is only one primary channel with a bandwidth of 20MHz; when the channel bandwidth is greater than 20MHz, there is one primary channel with a bandwidth of 20MHz, and the remaining one or more 20MHz channels are non-primary channels. The primary 20MHz channel is the common channel of operation for stations that are members of the basic service set (BSS). Stations in the BSS can compete for channel resources on the primary 20MHz channel. During channel contention, if the primary channel is in an OBSS busy state (OBSS interference), for example, if it is occupied by other devices in the same OBSS as the WLAN, and these other devices are sending Physical Protocol Data Units (PPDUs) on the primary channel, then the primary channel is in an OBSS busy state. If the primary channel is in an OBSS busy state, in order to make full use of channel resources, communication can be switched to a secondary channel to improve the throughput of the communication system and maximize the utilization of channel resources.

[0095] In this embodiment of the disclosure, the first device includes a first AP, such as a reporting AP; the second device includes a second AP and / or a third AP; the second AP is such as a non-transmitted AP; and the third AP is such as a transmitting AP.

[0096] Specifically, in a WLAN, a Multiple BSSID set is a collection of cooperating APs. All cooperating APs use the same operation set, channel number, and antenna interface. Within the Multiple BSSID set, typically only one AP transmits a BSSID (Transmitted BSSID), while the others are non-transmitted BSSIDs. Information about the Multiple BSSID set (i.e., the Multiple BSSID elements) is carried in beacon frames, probe response frames, or neighbor reports sent by the Transmitted BSSID APs. Correspondingly, the BSSID information of non-transmitted BSSID APs is derived by receiving the Multiple BSSID elements in the aforementioned beacon frames, probe response frames, or neighbor reports.

[0097] In the Multiple BSSID mechanism, a physical AP can virtualize multiple logical APs to form a Multiple BSSID set. Each virtualized AP manages one BSS. Different logical APs generally have different SSIDs and permissions, such as security mechanisms or transmission opportunities. In the Multiple BSSID set, one AP's BSSID is configured as a transmitting (or transmitting) BSSID, called a reporting AP or transmitting AP, such as the first AP and the third AP in this embodiment. The BSSIDs of other APs are configured as non-transmitted BSSIDs, called reported APs or non-transmitted APs, such as the second AP.

[0098] Generally speaking, multiple APs in a Multiple BSSID can be understood as one AP device virtually creating multiple cooperating AP devices. Only the AP with the Transmitted BSSID can send management frames, such as beacon frames and probe response frames. If the probe request frame sent by the STA is addressed to an AP with a non-transmitted BSSID in the Multiple BSSID set, then the AP with the Transmitted BSSID needs to respond to the probe response frame. The beacon frame sent by the AP with the Transmitted BSSID includes the Multiple BSSID element; other APs with non-transmitted BSSIDs cannot send beacon frames.

[0099] The first device carries first identification information in the first radio frame, such as a management frame, a beacon frame, or a probe response frame. The first identification information identifies: the first NPCA primary channel information of the first device and / or the second NPCA primary channel information of the second device. In this embodiment, the NPCA primary channel includes the channel accessed through a non-primary channel when accessing via a non-primary channel; for example, if the STA's operating bandwidth is 80MHz, then when the primary 40MHz channel is detected as busy in the OBSS, access is made through a 40MHz non-primary channel, for example, selecting 20MHz of the 40MHz secondary channel as the NPCA primary channel, i.e., the accessed NPCA primary channel is this 20MHz channel; the NPCA primary channel information includes, for example, at least one of the following: channel identifier, operating bandwidth, center frequency, or operating class information.

[0100] In this context, the first device, whose BSSID is a Transmitted BSSID, simultaneously transmits the second NPCA main channel information of the second device when sending (e.g., broadcasting) its first NPCA main channel information. It is understood that the second NPCA main channel information of one or more second devices may be carried in the first radio frame, and this disclosure does not limit this.

[0101] Specifically, when the second device includes a non-transmitted AP, it cannot send management frames. Instead, it sends a first radio frame through the first device to broadcast the second NPCA main channel information to other devices to meet the requirements of the UHR. For example, the first NPCA main channel information and the second NPCA main channel information are carried in the multiple BSSID set element or the multi-link information element of the first radio frame.

[0102] When the second device includes a transmitted AP, its second NPCA primary channel information can also be transmitted through the first radio frame sent by the first device. For example, the first radio frame carries a Reduced Neighbor Report (RNR) information element, and the RNR information element carries the second NPCA primary channel information. The first device also sends the first radio frame to broadcast the second NPCA primary channel information to other devices, thereby adapting to the UHR requirements.

[0103] Step 202: Send the first wireless frame to the third device.

[0104] The first device carries first identification information in the first radio frame, which identifies: the first NPCA main channel information of the first device and / or the second NPCA main channel information of the second device, in order to meet the requirements of UHR.

[0105] Figure 3 is a second interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 3, the above method includes:

[0106] Step 301: The first device determines the first radio frame; wherein the first radio frame identifies the first NPCA main channel information of the first device and the identification information of the second AP.

[0107] The first device includes a first AP; the BSSID of the first AP is configured as a Transmitted BSSID, such as a reporting AP; the second AP includes a non-transmitted AP, whose BSSID is configured as a non-transmitted BSSID, such as a reported AP. If the second AP cannot transmit management frames, it transmits a first radio frame through the first device to broadcast the second NPCA main channel information to other devices to meet the requirements of UHR.

[0108] Wherein, the first device and the second AP belong to the same BSSID set, and the first radio frame carries the first NPCA main channel information and the identification information of the second AP; wherein, the first device and the second AP are attached to different AP MLDs, and the multiple BSSID set element in the first radio frame includes the non-transmitted BSSID, that is, the non-transmitted BSSID corresponding to the second AP, which is used to identify the identity of the second AP;

[0109] Furthermore, the first radio frame does not carry the second NPCA main channel information, indicating that the second NPCA main channel information is the same as the first NPCA main channel information, that is, the information of the reported AP is consistent with the information of the reporting AP. The NPCA main channel information of the reported AP is identified by an implicit identifier.

[0110] For example, as shown in Table 1 below, the multiple BSSID set element of the first radio frame includes only the first NPCA main channel information and the non-transmitted BSSID corresponding to each of the second APs.

[0111] Table 1:

[0112] Table 1 shows some fields of the multiple BSSID set element, which includes the first NPCA main channel information and n non-transmitted BSSIDs corresponding to the second APs.

[0113] Step 302: Send the first wireless frame.

[0114] The first device carries first identification information in the first radio frame, which identifies: the first NPCA main channel information of the first device and / or the second NPCA main channel information of the second device, in order to meet the requirements of UHR.

[0115] Figure 4 is a third interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 4, the above method includes:

[0116] Step 401, the first device determines the first radio frame; wherein the first radio frame identifies the first NPCA main channel information of the first device and the identification information of the second AP.

[0117] The first device includes a first AP; the BSSID of the first AP is configured as a Transmitted BSSID, such as a reporting AP; the second AP includes a non-transmitted AP, whose BSSID is configured as a non-transmitted BSSID, such as a reported AP. If the second AP cannot transmit management frames, it transmits a first radio frame through the first device to broadcast the second NPCA main channel information to other devices to meet the requirements of UHR.

[0118] The first device and the second AP are attached to the same AP MLD. The multiple BSSID set element in the first radio frame includes the non-transmitted BSSID. The first device and the second AP belong to the same BSSID set. The first radio frame carries the first NPCA main channel information and the identification information of the second AP, but does not carry the second NPCA main channel information. It indicates that the second NPCA main channel information is the same as the first NPCA main channel information, that is, the information of the reported AP is consistent with the information of the reporting AP. The NPCA main channel information of the reported AP is identified by an implicit identification method.

[0119] The identification information of the second AP includes the non-transmitted BSSID corresponding to the second AP;

[0120] The first device and the second AP are attached to the same AP MLD. Each station in the multi-link information element of the first radio frame carries the non-transmitted BSSID in the per-STA profile field. That is, the non-transmitted BSSID corresponding to the second AP is used to identify the identity of the second AP. For example, the per-STA profile field in the multi-link information element of the first radio frame only includes the first NPCA main channel information and the non-transmitted BSSID corresponding to each second AP.
