This effectively avoids P2P transmission failure caused by one party being in a low-power state, ensuring both device-level power optimization and P2P link transmission reliability. However, if, within the same basic service set, the first STA and the second STA fail to inform each other of their DPS mode support and operating parameters during the discovery that the other is a TDLS (Tunneled Direct Link Setup) device or the establishment of a TDLS direct link, the peer device may be unable to effectively initiate or respond to P2P transmission. Furthermore, existing mechanisms stipulate that when a non-AP STA is in DPS mode, its associated AP is responsible for determining whether to send an initial control frame based on the DPS parameters. In a P2P scenario, if one party to the communication is in DPS mode, the other party's device must also have similar recognition and triggering capabilities to ensure the reliability of direct link communication.

[0074] In a first aspect, embodiments of this disclosure propose a parameter negotiation method applied to a first STA, the method comprising:

[0076] The first identification information is used to indicate whether the first STA supports Dynamic Power Saving Mode (DPS).

[0077] The second identification information is used to indicate whether the first STA supports sending the DPS initial control frame;

[0078] The third identification information is used to indicate whether the first STA enables DPS mode and / or DPS operation parameters.

[0079] In the above embodiments, through signaling interaction, the peer device (second STA) can clearly know the DPS capability and status of the first STA at the beginning or during the establishment of the TDLS link. Thus, when either TDLS peer device enters DPS mode, the other party can determine and execute the correct communication initialization process based on pre-negotiated information (e.g., sending an initial control frame to wake up the other party when necessary). This effectively avoids P2P transmission failures caused by one party being in a low-power state, ensuring both device-level power optimization and P2P link transmission reliability. However, if, within the same basic service set, the first STA and the second STA fail to inform each other of their DPS mode support and operating parameters during the discovery that the other is a TDLS (Tunneled Direct Link Setup) device or the establishment of a TDLS direct link, the peer device may be unable to effectively initiate or respond to P2P transmission. Furthermore, existing mechanisms stipulate that when a non-AP STA is in DPS mode, its associated AP is responsible for determining whether to send an initial control frame based on the DPS parameters. In a P2P scenario, if one party to the communication is in DPS mode, the other party's device must also have similar recognition and triggering capabilities to ensure the reliability of direct link communication.

[0129] Figure 1 This is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0130] like Figure 1 As shown, the communication system 100 includes a first station (STA) 102, a second STA 102, and an access point (AP) 103.

[0131] In some embodiments, access point device 103 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 an Ethernet network. 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.

[0132] In some embodiments, the first STA101 and the second STA102 include, 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.

[0133] Specifically, the first STA101 and the second STA102 can be terminal devices or network devices equipped with Wi-Fi chips. Optionally, the first STA101 and the second STA102 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 are not limited to these.

[0134] 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.

[0135] 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.

[0136] The following embodiments of this disclosure can be applied to Figure 1 The communication system 100 shown, or a part thereof, but not limited to it. Figure 1 The entities shown are illustrative; a communication system may include... Figure 1 All or part of the main body, or may include Figure 1 Other entities besides the main body, the number and form of each entity are arbitrary, each entity can be physical or virtual, the connection relationship between the entities is illustrative, the entities can be unconnected or connected, and 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.

[0137] 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.

[0138] Figure 2 This is one of the interactive schematic diagrams illustrating a parameter negotiation method according to an embodiment of this disclosure. For example... Figure 2 As shown, the above method includes:

[0139] Step 201: During the TDLS discovery process or TDLS link establishment process, the first STA sends a first radio frame, which includes at least one of the following pieces of information:

[0140] The first identification information is used to indicate whether the first STA supports Dynamic Power Saving Mode (DPS).

[0141] The second identification information is used to indicate whether the first STA supports sending the DPS initial control frame;

[0142] The third identification information is used to indicate whether the first STA enables DPS mode and / or DPS operation parameters.

[0143] Step 201 may include: Step 201A, during the TDLS discovery process or the TDLS link establishment process, the first STA sends a first radio frame to the AP; Step 201B, during the TDLS discovery process or the TDLS link establishment process, the AP forwards the first radio frame to the second STA (sends a third radio frame).

[0144] Step 201 may also include: Step 201C, in the TDLS discovery process, the first STA sends a first radio frame to the second STA.

[0145] Step 202: The second STA receives the first radio frame or the third radio frame during the TDLS discovery process or the TDLS link establishment process.

[0146] Step 203: The second STA sends a second radio frame to the first STA via the TDLS link or via the AP, based on at least one of the first identification information, the second identification information, and the third identification information.

[0147] The next-generation Wi-Fi technology, Ultra High Reliability (UHR) wireless LAN, also known as the IEEE 802.11bn standard, aims to significantly improve the reliability of wireless connections, reduce communication latency, and optimize the power consumption of terminal devices. In this architecture, most UHR devices are designed as multi-link devices (MLDs). When UHR access points (APs) and UHR stations (STAs) use a multi-link approach for data transmission, their power-saving mechanisms need to be further enhanced to adapt to the new system architecture.

[0148] To meet this requirement, the 802.11bn working group proposed a new power management mechanism—Dynamic Power Save (DPS)—during the standards discussion. For example, a UHR STA can operate in Dynamic Power Save mode. When Dynamic Power Save mode is enabled, the UHR STA switches to Low Capability (LC) mode. In LC mode, the device's communication capabilities are limited; for example, it only supports single spatial stream and low-rate modulation and coding scheme (MCS) for transmission and reception, with a communication bandwidth of 20MHz, and only supports receiving specific control or management frames. Furthermore, if a peer device needs to exchange frames with it, the peer device must send an initial control frame to switch it from Low Capability mode to a higher capability mode, thereby enabling frame exchange with the peer device. The initial control frame is used to instruct the receiver to switch from a low-capability mode to a high-capability mode in dynamic power-saving mode. For example, the initial control frame is transmitted as a non-HT (duplicate) PPDU at a rate of 6Mb / s, 12Mb / s, or 24Mb / s. The initial control frame can be a Buffer Status Report Poll non-trigger-based (BSRP NTB) trigger frame, a Buffer Status Report Poll (BSRP) trigger frame, or a Multiple User Request to Send (MU-RTS) trigger frame.

[0149] In this embodiment of the disclosure, the STA that supports DPS mode is called a DPS STA, and the STA that can send an initial control frame to the DPS STA to initiate communication (usually an AP or other device with coordination function) is called a DPS Assisting STA.

[0150] In IEEE 802.11bn draft 0.3, the working group has reached a preliminary consensus on the definitions of high and low capability modes. Low capability modes are further divided into default mode and parameter mode. In default mode, the device operates using predefined low-power parameters, such as 20MHz bandwidth, single spatial stream, and low transmission rates of 6 / 12 / 24Mb / s, limited to a limited non-HT PPDU format. In parameter mode, the STA can report custom low capability operation parameters to the AP when requesting entry into the DPS, including but not limited to low capability mode bandwidth (LC Mode Bandwidth), spatial stream number (LC Mode Nss), and modulation and coding scheme (LC Mode MCS). Correspondingly, high capability mode refers to the communication capability state adopted by the STA after receiving the initial control frame from the peer device within the transmission opportunity (TXOP). Its operating bandwidth is no greater than the device's maximum bandwidth, and the spatial stream number is no greater than the number agreed upon when interacting with the peer STA.

[0151] Furthermore, in low-capability mode, the STA can indicate to the peer device whether it needs to receive an initial control frame before initiating frame exchange by setting the "ICF Required" flag. For example, if the flag is set to 1, the AP (or peer STA) must send an initial control frame to trigger its state switch before exchanging frames with it; conversely, if it is set to 0, the AP can directly interact with the STA using frames without a prior wake-up procedure. The STA reports its low-capability mode parameters and ICF requirement during the DPS request phase, enabling the AP to trigger the STA to return to high-capability state at the appropriate time and in the correct manner.

[0152] However, current discussions and designs regarding DPS primarily focus on infrastructure network scenarios between non-AP sites and APs, while peer-to-peer (P2P) transmission scenarios have not been adequately considered. Therefore, given that UHR non-AP STAs support DPS mode, to ensure controllable and efficient transmission between devices in P2P scenarios, it is urgent to design and enhance the corresponding signaling interaction and process specifications.

[0153] In this embodiment of the disclosure, after establishing a TDLS link, the first STA and the second STA become peer TDLS devices. Specifically, TDLS, or Tunneled Direct Link Setup, allows two non-AP STAs within the same Basic Service Set (BSS) to directly establish and maintain a peer-to-peer (P2P) communication link after discovering each other, without having to forward data traffic through their associated access points (APs), thereby effectively reducing transmission latency and network load.

[0154] During the TDLS discovery process or TDLS link establishment process, the first STA sends information about its DPS support capabilities to the second STA through the AP. The first radio frame is used for the TDLS discovery and link establishment process. Optionally, the first radio frame includes at least one of the TDLS discovery request frame, TDLS setup request frame, and TDLS discovery response frame.

[0155] Specifically, to establish a TDLS link, devices need to perform TDLS discovery and link establishment procedures. For example, during TDLS discovery, devices probe and discover potential directly connected peer devices through the interaction of TDLSDiscovery Request and TDLSDiscovery Response frames; the TDLSDiscovery Request frame requires forwarding by the access point device, while the TDLSDiscovery Response frame does not require forwarding by the access point. Furthermore, devices can also probe and discover potential directly connected peer devices by sending TDLSDiscovery Respons frames; upon receiving such a TDLSDiscovery Respons frame, the peer device responds by sending a TDLSDiscovery Response frame. During TDLS link establishment, devices negotiate link parameters and ultimately establish a direct link by exchanging TDLS Setup Request and TDLS Setup Response frames.

[0156] During the TDLS discovery process or TDLS link establishment process, the first STA informs the other party of its Dynamic Power Saving Mode (DPS) capabilities and status by sending a first radio frame. The identification information carried in the first radio frame includes at least one or more of the following:

[0157] First identification information: Used to indicate whether the first STA itself supports DPS mode. For example, if the first identification information is set to "0", it indicates that the first STA itself does not support DPS mode; if the first identification information is set to "1", it indicates that the first STA itself supports DPS mode; the first identification information is, for example, the DPS Support field in the UHR Capabilities element.

[0158] The second identification information indicates whether the first STA supports acting as a DPS assisted STA to send initial control frames (ICFs) to peer devices in DPS mode. For example, the first identification information could be the DPSAssisting Support field identifier in the UHR Capabilities element.

[0159] The third identification information is used to indicate whether the first STA has enabled (turned on) DPS mode and / or its configured DPS operating parameters (such as bandwidth, spatial stream, modulation and coding scheme, etc. in low capability mode).

[0160] It is understandable that when the first STA does not support DPS mode, the first radio frame does not contain third identification information;

[0161] Through the aforementioned signaling interaction, the peer device (second STA) can clearly know the DPS capability and status of the first STA at the beginning or during the establishment of the TDLS link. Thus, when either TDLS peer device enters DPS mode, the other can determine and execute the correct communication initialization process based on pre-negotiated information (e.g., sending an initial control frame to wake up the other party when necessary). This effectively avoids P2P transmission failures caused by one party being in a low-power state, ensuring both device-level power optimization and P2P link transmission reliability. However, if, within the same basic service set, the first and second STAs fail to inform each other of their DPS mode support and operating parameters during the discovery of the other as a TDLS (Tunneled Direct Link Setup) device or the establishment of a TDLS direct link, the peer device may be unable to effectively initiate or respond to P2P transmissions. Furthermore, the existing mechanism stipulates that when a non-AP STA is in DPS mode, its associated AP is responsible for determining whether to send an initial control frame based on the DPS parameters. In a P2P scenario, if one party to the communication is in DPS mode, the other party's device must also have similar recognition and triggering capabilities to ensure the reliability of direct link communication.

[0162] In some embodiments, the first radio frame includes at least one of a TDLS Discovery Request frame, a TDLS Setup Request frame, and a TDLS Discovery Response frame;

[0163] The first radio frame includes one of a TDLS Discovery Request frame and a TDLS Setup Request frame, and the first STA sends the first radio frame to the AP;

[0164] The first radio frame includes a TDLS Discovery Response frame, which the first STA sends to the second STA.

[0165] During the TDLS discovery process, the first STA detects and discovers potential directly connected peer devices by sending TDLSDiscovery Request frames; during the TDLS link establishment process, the first STA negotiates link parameters and finally establishes a directly connected link by exchanging TDLSSetup Request frames and TDLS Setup Response frames.

[0166] In some embodiments, the first radio frame includes a first element; the first element is, for example, a UHRCapabilities element.

[0167] The first identification information and / or the second identification information are carried in the first field of the first element, such as the UHR Medium Access Control (MAC) Capabilities Information field.

[0168] For example, the TDLSDiscovery Request frame contains a UHR Capabilities element, and the first identification information and / or the second identification information are contained in the UHR MACCapabilities Information field of the UHR Capabilities element.

[0169] In some embodiments, the first radio frame includes: a second element; the second element is, for example, a TDLS multi-link element;

[0170] The third identification information is carried in the first identification field of the second field in the second element; the second field is, for example, the site configuration field (STA Profile field); the first identification field is, for example, the Mode Tuple field of the UHR Mode Change element containing ModeSpecific Parameters for DPS.

[0171] The second identifier field (e.g., Link ID subfield) of the second field identifies the link where the first STA is located; for example, the third identifier information is contained in the first identifier field of the STA Profile field (second field) in the first Per-STA Profile subelement of the Link Info field; the first identifier field is, for example, the Link ID subfield, and the Link ID subfield of the STA Control field in the first Per-STA Profile subelement identifies the link where the UHR non-AP STA1 is located.

[0172] Alternatively, the third identification information may be carried in the third identification field of the third element. The third element may be, for example, a UHR Mode Change element, and the third identification field may be, for example, a Mode Tuple field. The third identification information may be carried in the Mode Tuple field of the Mode Specific Parameters for DPS of the UHR Mode Change element.

[0174] Step 301: During the TDLS discovery process, the first STA sends the first radio frame to the AP;

[0178] The second identification information is used to indicate whether the first STA supports sending the DPS initial control frame;

[0179] The third identification information is used to indicate whether the first STA enables DPS mode and / or DPS operation parameters.

[0180] Step 302: The AP receives a first radio frame sent by the first STA, and in response to the first radio frame, sends a third radio frame to the second STA; wherein the third radio frame includes at least one of the following information:

[0181] The first identification information, the second identification information, and the third identification information.

[0182] The third radio frame includes the TDLS Discovery Request frame.

[0188] Through the above signaling interaction, the peer device (second STA) can clearly know the DPS capabilities and status of the first STA during the TDLS discovery process.

[0189] After receiving the third radio frame, the second STA sends a second radio frame to the first STA via the TDLS link based on at least one of the first identification information, the second identification information, and the third identification information.

[0194] Through the above signaling interaction, the peer device (second STA) can inform the first STA of its DPS capabilities and status during the TDLS discovery process.

[0195] Specifically, during the TDLS discovery process, if the first STA sends a TDLSDiscovery Request frame, the second STA will reply with a TDLSDiscovery Response frame. The TDLSDiscovery Response frame is sent to the first STA via a direct link.

[0196] Figure 4 This is the third interactive schematic diagram of the parameter negotiation method shown according to the embodiments of this disclosure.

[0197] Step 400: The first STA receives the fourth radio frame sent by the second STA.

[0198] Step 401: During the TDLS discovery process, the first STA sends the first radio frame to the second STA;

[0199] The first radio frame includes a TDLS Discovery Response frame.

[0200] The first wireless frame includes at least one of the following information:

[0202] The second identification information is used to indicate whether the first STA supports sending the DPS initial control frame;

[0203] The third identification information is used to indicate whether the first STA enables DPS mode and / or DPS operation parameters.

[0204] Step 402: After receiving the first radio frame, the second STA sends a second radio frame to the first STA, requesting the establishment of a TDLS link; wherein the second radio frame contains at least one of the following information:

[0205] The first identification information, the second identification information, and the third identification information.

[0206] The third radio frame includes a TDLS Setup frame.

[0207] Step 403: The AP receives the second radio frame sent by the second STA and forwards the second radio frame to the first STA.

[0208] The forwarded second radio frame includes at least one of the following information:

[0209] The fourth identification information is used to indicate whether the second STA supports DPS mode;

[0210] The fifth identification information is used to indicate whether the second STA supports sending the DPS initial control frame;

[0211] The sixth identification information is used to indicate whether the second STA enables DPS mode and / or DPS operation parameters.

[0212] Through the above signaling interaction, the peer device (second STA) can clearly know the DPS capabilities and status of the first STA during the TDLS discovery process.

[0213] After receiving the first radio frame, the second STA sends a second radio frame to request TDLS establishment. The second radio frame includes a TDLS Setup Request frame.

[0214] The second wireless frame includes at least one of the following information:

[0215] The fourth identification information is used to indicate whether the second STA supports DPS mode;

[0216] The fifth identification information is used to indicate whether the second STA supports sending the DPS initial control frame;

[0217] The sixth identification information is used to indicate whether the second STA enables DPS mode and / or DPS operation parameters.

[0218] Through the above signaling interaction, the peer device (second STA) can inform the first STA of its DPS capabilities and status during the TDLS establishment process.

[0219] In this embodiment, before the first STA sends the first radio frame in step 401, it further includes receiving a fourth radio frame sent by the second STA. The fourth radio frame includes a TDLS Discovery Response frame.

[0220] Figure 5 This is the fourth interactive schematic diagram of the parameter negotiation method shown according to the embodiments of this disclosure.

[0221] Step 501: During the TDLS establishment process, the first STA sends the first radio frame to the AP;

[0222] The first radio frame includes a TDLS Setup Request frame.

[0223] The first wireless frame includes at least one of the following information:

[0224] The first identification information is used to indicate whether the first STA supports Dynamic Power Saving Mode (DPS).

[0225] The second identification information is used to indicate whether the first STA supports sending the DPS initial control frame;

[0226] The third identification information is used to indicate whether the first STA enables DPS mode and / or DPS operation parameters.

[0227] Step 502: The AP receives the first radio frame sent by the first STA, and in response to the first radio frame, sends a third radio frame (forwarding the first radio frame) to the second STA; wherein the third radio frame includes at least one of the following information:

[0228] The first identification information, the second identification information, and the third identification information.

[0229] The third radio frame includes a TDLS Setup Request frame.

[0230] Step 503: The second STA receives the third radio frame.

[0231] The third radio frame includes at least one of the following information:

[0232] The first identification information is used to indicate whether the first STA supports Dynamic Power Saving Mode (DPS).

[0233] The second identification information is used to indicate whether the first STA supports sending the DPS initial control frame;

[0234] The third identification information is used to indicate whether the first STA enables DPS mode and / or DPS operation parameters.

[0235] Through the above signaling interaction, the peer device (second STA) can clearly know the DPS capabilities and status of the first STA during the TDLS establishment process.

[0236] After receiving the third radio frame, the second STA sends a second radio frame to the first STA via the UHR AP based on at least one of the first identification information, the second identification information, and the third identification information. The second radio frame includes a TDLS Discovery Request frame. For example, step 503 includes the second STA sending the second radio frame; step 504 includes the AP sending a fifth radio frame (forwarding the second radio frame) after receiving the second radio frame.

[0237] The second wireless frame includes at least one of the following information:

[0238] The fourth identification information is used to indicate whether the second STA supports DPS mode;

[0239] The fifth identification information is used to indicate whether the second STA supports sending the DPS initial control frame;

[0240] The sixth identification information is used to indicate whether the second STA enables DPS mode and / or DPS operation parameters.

[0241] Through the above signaling interaction, the peer device (second STA) can inform the first STA of its DPS capabilities and status during the TDLS discovery process.

[0242] Specifically, during TDLS establishment, the first STA informs the second STA of its DPS capabilities, status, or operating parameters in DPS mode through the UHR AP; that is, the first STA sends a first radio frame to the UHR AP, and the UHR AP forwards the first radio frame to the second STA (and sends a third radio frame to the second STA). After receiving the first radio frame, the second STA forwards the second radio frame through the UHR AP, informing the first STA of its DPS capabilities, status, or operating parameters in DPS mode.

[0243] In some embodiments, the second radio frame includes a first element, such as a UHR Capabilities element. The fourth and / or fifth identification information is carried in a first field of the first element, such as a UHR MAC Capabilities Information field.

[0244] In some embodiments, the second radio frame includes a second element, such as a TDLS Multi-Link element. The sixth identification information is carried in the first identification field of the second field of the second element. For example, the sixth identification information may be contained in a specific identification field within the STAProfile field of a Per-STA Profile sub-element of the Link Info field, which may be the Mode Tuple field defined for DPS mode within the UHR Mode Change element. Meanwhile, the second identification field of the second field (e.g., the Link ID sub-field) is used to identify the operating link to which the second STA resides.

[0245] Alternatively, in some embodiments, the sixth identification information may also be carried in the third identification field of the third element. For example, the third element may be a UHR Mode Change element, and the third identification field may be a Mode Tuple field defined therein, specifically used to carry the specific operating parameters of the DPS mode.

[0246] This embodiment of the disclosure achieves complete interaction of DPS capabilities and parameters between TDLS peer devices through the aforementioned signaling process. This enables the peer device to accurately determine whether to send an initial control frame to wake up the other party based on the information obtained at this stage in subsequent P2P communication if either device enters DPS mode, thereby ensuring the communication reliability of the direct link in a low-power state and effectively solving the transmission interruption problem caused by DPS mode in P2P scenarios.

[0247] In this embodiment, during the TDLS discovery process or the establishment of a DLS link, the capability information and / or operating parameter information of the dynamic power-saving mode are communicated to the peer TDLS device. The first STA can be a TDLS initiator or a TDLS responder. The peer TDLS non-AP STA needs to feed back the capability information and / or operating parameter information of the dynamic power-saving mode in the response frame. In this way, through the interaction of relevant capability information and / or relevant operating parameters, the TDLS devices can effectively avoid the phenomenon of transmission failure caused by the peer device being in DPS mode when an established TDLS link is established, thereby reducing device-level power consumption while ensuring the reliability of P2P transmission.

[0248] In some embodiments, after the first STA and the second STA establish a TDLS link, the method further includes:

[0249] If the first STA enters DPS mode and the first STA requires the peer device to send an initial control frame before initial frame interaction, then the first STA receives the DPS initial control frame sent by the second STA before performing frame interaction with the second STA.

[0250] After the first STA and the second STA successfully establish a TDLS link, if the first STA enters DPS mode and sets the "ICF Required" flag to valid (e.g., set to 1) in its previously negotiated DPS operation parameters, indicating that it requires the peer device to send an initial control frame before engaging in frame interaction, then the first STA will first listen for and receive the DPS initial control frame sent by the second STA before preparing to exchange any data or management frames with the second STA. Receiving this DPS initial control frame will trigger the first STA to switch from low-capability mode to high-capability mode, thereby preparing for subsequent complete frame interaction with the second STA.

[0251] In some embodiments, after the first STA and the second STA establish a TDLS link, the method further includes:

[0252] If the second STA enters DPS mode and the second STA requires the peer device to send an initial control frame before initial frame interaction, then the first STA sends a DPS initial control frame to the second STA before performing frame interaction with the second STA.

[0253] After the first STA and the second STA successfully establish a TDLS link, if the second STA enters DPS mode and its DPS operation parameters indicate that it needs an initial control frame (i.e., its "ICF Required" flag is set to active), the first STA will proactively send a DPS initial control frame to the second STA before initiating frame interaction with it. This action by the first STA is a manifestation of its DPS auxiliary STA function. By sending this trigger frame, it wakes up the second STA, which is in a low-capability state, and switches it to a high-capability mode, thereby establishing a state where both parties can communicate normally.

[0254] In some embodiments, the DPS initial control frame includes at least one of a BSRP NTB Trigger frame and an RTS frame.

[0255] When using the BSRP NTB Trigger frame, this frame is suitable for coordinating buffer status reporting and wake-up timing in multi-link device (MLD) scenarios, and can trigger state transitions of peer devices and negotiate subsequent transmission resources.

[0256] When using RTS frames, which act as control frames, the receiver is expected to reply with a CTS (Clear to Send) frame to complete a handshake interaction. This interaction process itself enables the receiving STA in DPS low-capability mode to recognize the communication intent and wake up to high-performance mode accordingly.

For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD).

For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
