[0118] As shown in Figure 1, the communication system 100 includes a station (STA) 101 and an access point (AP) 102.

[0119] In some embodiments, STA 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 may be at least one of, but is not limited to, a mobile phone, a wearable device, an IoT device that supports WiFi communication, a car with WiFi 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, or a wireless terminal device in a smart home.

[0120] Specifically, the STA 101 can be a terminal device or network device with a Wi-Fi chip. Optionally, the STA 101 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.

[0121] In some embodiments, AP 102 can be an access point for mobile terminals to access a wired network. The 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, the 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.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] 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 the Access Point (AP) device, and all other STAs in the network are associated with it. Other sites in the BSS network that are not the central site are called terminals, also known as non-AP STAs; terminals and non-AP STAs are collectively referred to as STAs. When describing STAs, it is not necessary to distinguish between terminals 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.

[0126] Figure 2 is an interactive schematic diagram of a power-saving mode identification method according to an embodiment of the present disclosure. As shown in Figure 2, the method includes:

[0127] Step 201, the site device STA 101 determines the first radio frame; the first radio frame includes first identification information and second identification information;

[0128] The first identification information identifies the power-saving mode information of the first STA;

[0129] The second identification information identifies the power saving mode information of one or more second STAs;

[0130] The first STA and the second STA are attached to the same multi-link site device (non-AP MLD).

[0131] In this embodiment, the method for identifying the power saving mode (PS mode) of a device in a multi-link environment is optimized to better manage device power consumption and improve network efficiency. First, this application extends the definition of device power saving mode in the current WiFi standard, including indicating the power mode of the first STA through the power management (PM) subfield of the frame control (FC) field in the media access control (MAC) header of the first wireless frame sent by the STA. The power mode includes active mode and power saving mode (PS mode), with PS mode further subdivided into doze state.

[0132] To improve throughput and reduce network latency, this application incorporates a Multi-Link Operation (MLO) mechanism. In the network architecture of this application, devices supporting MLO are referred to as Multi-Link Devices (MLDs), including AP MLDs and non-AP MLDs. The AP MLDs and non-AP MLDs are connected by their respective working links, one for the first STA and one for the second STA. In this multi-link configuration, the power-saving mode information of devices on each link exists independently.

[0133] In this embodiment of the disclosure, to achieve power saving for the device, especially on the STA side, the STA can switch from a low-capacity communication mode to a high-capacity communication mode. Furthermore, through second identification information, the non-AP MLD indicates the PM mode of one or more of its affiliated multi-link site devices (non-AP STAs) to its associated AP MLD (the AP MLD supporting this mechanism) on an enabled link. In this low-capacity communication mode, at least one operating parameter is lower than that in the high-capacity communication mode; such parameters include one or more of the following: bandwidth (BW), number of spatial streams (NSS), MCS mode, and transmission rate.

[0134] Optionally, the low-capacity communication mode can also be called the listening state or low-power communication phase, for example, with operating parameters of 20MHz basic bandwidth, 1 SS, and MCS methods such as MCS0 to MCS6. The high-capacity mode refers to the high-power communication mode, for example, with operating parameters greater than or equal to 20MHz, a BW of 40 / 80 / 160 / 320MHz, 2 or more SS, and MCS methods such as MCS6 to MCS14, etc.

[0135] Specifically, in this embodiment of the disclosure, for a non-AP MLD and an AP MLD supporting the 802.11bn transmission protocol, after establishing an initial association and completing data interaction under the first link, the STA determines a first radio frame. The STA is a non-AP STA attached to the non-AP MLD. The first radio frame can be a physical protocol data unit (PPDU) frame, and the first radio frame includes first identification information and second identification information. The first identification information identifies the power-saving mode information of the first STA; the second identification information identifies the power-saving mode information of one or more second STAs; the second STA and the first STA are attached to the same multi-link site device, the non-AP MLD. The power-saving modes include, but are not limited to, sleep mode, active mode, first capability communication mode, and second capability communication mode. The first capability communication mode includes a low-capability communication mode, and the second capability communication mode includes a high-capability communication mode. The following description uses the first capability communication mode as a low-capability communication mode and the second capability communication mode as a high-capability communication mode.

[0136] This disclosure provides a power-saving mode identification method for multi-link devices supporting the 802.11bn protocol, particularly in multi-link operating environments. By carrying first and second identification information in the first radio frame, the power-saving mode of the device under each link can be clearly identified. Specifically, the first identification information provides the power-saving mode information of the first STA, while the second identification information covers the power-saving mode information of second STAs under other links besides the link where the first STA is located. These second STAs belong to the same non-AP MLD as the first STA. The second identification information enables cross-link power-saving mode identification, optimizing energy efficiency management under each link and meeting UHR transmission requirements. Furthermore, this disclosure maintains good forward compatibility with the 802.11bn transmission protocol, ensuring a smooth transition between the old and new standards.

[0137] Step 202: The STA 101 transmits the first radio frame under the first link.

[0138] In this embodiment of the present disclosure, the STA sends a first radio frame to the corresponding AP under the first link. The first radio frame includes first identification information and second identification information.

[0139] In some embodiments, the first identification information is set to a first parameter value to indicate that the first STA is in a dormant state; the first identification information is set to a second parameter value to indicate that the first STA is in an active state.

[0140] The second identification information is set to the first parameter value to identify that the second STA is in a sleep state or a low-capability communication mode; the second identification information is set to the second parameter value to identify that the second STA is in an active state or a high-capability communication mode.

[0141] In the low-capability communication mode, the value of at least one operating parameter is lower than that in the high-capability communication mode.

[0142] In this embodiment of the disclosure, the first identification information is set in the PM subdomain of the Frame Control field of the first radio frame; the second identification information is set in the A-control field of the High Throughput Control (HT-control) field of the first radio frame. For example, the first identification information may be a bit in the PM subdomain used to identify the power saving mode information of the first STA; the second identification information may be a bit in the A-control field used to identify the power saving mode information between the non-AP MLD and the AP MLD, and other links besides the link where the first STA is located.

[0143] In some embodiments, the first identification information can be set to a first parameter value or a second parameter value, such as setting the PM bit to "1" or "0" to identify the power saving mode information of the first STA. Specifically, when the PM bit is set to "1", it indicates that the first STA is in a sleep state; when the PM bit is set to "0", it indicates that the first STA is in an active state or Active Mode.

[0144] In some embodiments, the second identification information may be carried in the cross-link power saving (PS) mode information bit in the A-control field of the HT-control field of the first radio frame. The cross-link PS mode information bit may be an 8-bit or 16-bit bit. When the cross-link PS mode information bit is set to "1", it indicates that the second STA under the corresponding link is in a sleep state or a low-capacity communication mode; when the cross-link PS mode information bit is set to "0", it indicates that the second STA under the corresponding link is in an active state or a high-capacity communication mode.

[0145] In some embodiments, the first wireless frame includes third identification information;

[0146] The first identification information is set to a first parameter value, and the third identification information is set to a first parameter value, indicating that the first STA is in a sleep state or has entered the first capability communication mode;

[0147] The first identification information is set to the second parameter value, and the third identification information is set to the second parameter value, indicating that the first STA is in an active state or has entered the second capability communication mode.

[0148] In this embodiment of the disclosure, the A-control field of the HT-control field of the first wireless frame may also contain power-saving mode information of the first STA, namely, third identification information. The third identification information is used to identify the power-saving mode information of the first STA under the corresponding link in the A-control field, and it plays the same role as the PM bit. The third identification information ensures that the power-saving mode information of the first STA recorded in the A-control field is consistent with the power-saving mode information indicated by the PM bit. This means that the current power-saving state of the first STA can be known through either the PM bit or the third identification information in the A-control field. For example, the third identification information is carried in the cross-Link PS mode information bit in the A-control field of the HT-control field. When the PM bit is set to "1", it indicates that the STA under link 2 is in a sleep state, and when the cross-Link PS mode information bit is set to "00000010", it indicates that the STA under link 2 is in a sleep state or has entered a low-capacity communication mode. Alternatively, if the PM bit is set to "0", indicating that the STA under Link 2 is in a sleep state, and the cross-Link PS mode information bit is set to "11111101", then the STA under Link 2 is in an active state or has entered a high-capacity communication mode. By setting the third identification information, the consistency of the STA's power-saving state in different signaling fields can be effectively ensured. This method allows the AP to quickly determine the power-saving mode of the first STA based on the first and third identification information after receiving the first radio frame, further optimizing the network's energy efficiency management.

[0149] Step 203: AP 102 receives the first radio frame.

[0150] In this embodiment of the disclosure, the access point device (AP) attached to the multi-link access point device (AP MLD) receives a first radio frame under the first link; the first radio frame includes first identification information and second identification information.

[0151] The first identification information identifies the power-saving mode information of the first STA;

[0152] The second identification information identifies the power saving mode information of one or more second STAs;

[0153] The second STA and the first STA belong to the same non-AP MLD.

[0154] In this embodiment of the disclosure, the AP can clearly identify one or more second STAs and the power-saving mode information of the first STA by receiving the first radio frame. These devices all belong to the same non-AP MLD. This identification method not only helps the AP effectively manage and schedule the energy efficiency status of each device, but also optimizes network performance and resource utilization in a multi-link environment, improving overall communication efficiency.

[0155] In some embodiments, the first identification information is set to a reserved bit, and the second identification information is set to the first parameter value to identify one or more second STAs in a sleep state; the first identification information is set to a reserved bit, and the second identification information is set to the second parameter value to identify one or more second STAs in a low capability mode (listening mode) or a high capability mode.

[0156] For example, if the PM bit is set to "reserved", it indicates that the AP only needs to parse the HT-control field of the first radio frame after receiving it. The HT-control field includes the cross-Link PS mode information bit of the A-control field. If the cross-Link PS mode information bit is set to "1", it indicates that the STAs on links other than the first link are in sleep mode. If the cross-Link PS mode information bit in the HT-control field is set to "0", it indicates that the STAs on links other than the first link are in low-capability mode or high-capability mode.

[0157] By setting the first identifier as a reserved bit and setting the second identifier to a specific parameter value, the power-saving mode status of multiple second STAs can be effectively identified. For example, when the PM bit is set to "reserved," the AP only needs to parse the HT-control field after receiving the first radio frame, without needing to further parse the first identifier. Based on the setting of the cross-Link PS mode information bit in the A-control field of the HT-control field, "1" indicates that STAs other than the first link are in sleep mode, while "0" indicates low-capacity or high-capacity mode. This method simplifies the AP's processing flow, improves system response speed and efficiency, and helps optimize network management and energy efficiency control in multi-link environments.

[0158] In some embodiments, in addition to the communication scenarios provided in the above embodiments, there are also the following three communication interaction scenarios for STAs and APs that support the 802.11bn transmission protocol:

[0159] Communication Scenario 1: Non-AP MLD communicates with AP that does not support multi-link communication.

[0160] In this scenario, the power-saving mode identification method provided in this disclosure includes:

[0161] The first wireless frame includes first identification information; the first identification information identifies the power saving mode information of the first STA;

[0162] Wherein, the first identification information is set to a first parameter value to indicate that the first STA is in a dormant state; the first identification information is set to a second parameter value to indicate that the first STA is in an active state; the first identification information is set to a third parameter value to indicate that the first STA is in a low capability mode; and the first identification information is set to a fourth parameter value to indicate that the first STA is in a high capability mode.

[0163] For example, after a non-AP MLD establishes an initial association and completes data exchange with an AP that does not support multi-link communication, the first STA determines the first radio frame. The first radio frame includes PM bits. If the PM bits are set to "1", it indicates that the first STA is in a sleep state; if the PM bits are set to "0", it indicates that the first STA is in an active state. If the PM bits are set to other parameter values ​​besides "1" and "0", it indicates that the first STA is in a low-capability mode or a high-capability mode.

[0164] Communication Scenario 2: STAs that do not support multi-link communication communicate with AP MLDs.

[0165] In this scenario, the power-saving mode identification method provided in this disclosure includes:

[0166] The first wireless frame includes the first identification information; the first identification information identifies the power saving mode information of the first STA;

[0167] Wherein, the first identification information is set to a first parameter value to indicate that the first STA is in a dormant state; the first identification information is set to a second parameter value to indicate that the first STA is in an active state; the first identification information is set to a third parameter value to indicate that the first STA is in a low capability mode; and the first identification information is set to a fourth parameter value to indicate that the first STA is in a high capability mode.

[0168] For example, if a first STA that does not support multi-link communication establishes an initial association with an AP MLD on a single link and completes data exchange, the first STA determines the first radio frame. The first radio frame includes PM bits. If the PM bits are set to "1", it indicates that the first STA is in a sleep state; if the PM bits are set to "0", it indicates that the first STA is in an active state. If the PM bits are set to other parameter values ​​besides "1" and "0", it indicates that the first STA is in a low-capability mode or a high-capability mode.

[0169] Communication Scenario 3: A STA that does not support multi-link communication communicates with an AP that does not support multi-link communication.

[0170] In this scenario, the power-saving mode identification method provided in this disclosure includes:

[0171] The first data frame includes the first identification information; the first identification information identifies the power saving mode information of the first STA;

[0172] Wherein, the first identification information is set to a first parameter value to indicate that the first STA is in a dormant state; the first identification information is set to a second parameter value to indicate that the first STA is in an active state; the first identification information is set to a third parameter value to indicate that the first STA is in a low capability mode; and the first identification information is set to a fourth parameter value to indicate that the first STA is in a high capability mode.

[0173] For example, after a first STA that does not support multi-link communication establishes an initial association with an AP that does not support multi-link communication and completes data exchange, the first STA determines the first radio frame. The first radio frame includes PM bits. If the PM bits are set to "1", it indicates that the first STA is in a sleep state; if the PM bits are set to "0", it indicates that the first STA is in an active state. If the PM bits are set to other parameter values ​​besides "1" and "0", it indicates that the first STA is in a low-capability mode or a high-capability mode.

[0174] In some embodiments, the communication interaction between a STA that supports the 802.11bn transport protocol and an AP that does not support the 802.11bn transport protocol further includes:

[0175] The first data frame includes the first identification information; the first identification information identifies the power saving mode information of the first STA;

[0176] The first identification information is set to a first parameter value to indicate that the first link is in a dormant state; the first identification information is set to a second parameter value to indicate that the first link is in an active state.

[0177] For example, after a first STA that supports the 802.11bn transmission protocol establishes an association with an AP that does not support the 802.11bn transmission protocol and completes data exchange, the first STA determines the first radio frame. The first radio frame includes PM bits. If the PM bits are set to "1", it indicates that the first STA is in a sleep state; if the PM bits are set to "0", it indicates that the first STA is in an active state.
