[0038] The embodiments of the present disclosure provide a communication method, a communication device, and a communication system.

[0039] In a first aspect, an embodiment of the present disclosure provides a communication method, applied to a first device, the method comprising:

[0040] Sending a first radio frame to a second device associated with the first radio frame; wherein the first radio frame indicates whether the first device enables / disables a dynamic power saving mode and / or a first duration for enabling / disabling the dynamic power saving mode; and the first duration is used to indicate a maximum time limit for the second device to respond to the first radio frame;

[0041] Determine a time to enable / disable the dynamic power saving mode according to a response result of the second device to the first radio frame.

[0042] In the above embodiment, the first device sends a first radio frame containing dynamic power saving mode enable / disable information and a first duration to the second device, thereby explicitly specifying the maximum time limit for the second device to respond. Upon receiving the second device's response, the first device determines whether to enable / disable dynamic power saving mode for a specific duration based on the response, thereby improving energy efficiency while ensuring timely and stable communication.

[0043] In combination with some embodiments of the first aspect, in some embodiments, determining the time to enable the dynamic power saving mode according to a response result of the second device to the first radio frame includes one or more of the following:

[0044] receiving a second radio frame sent by the second device within the first duration, and determining a first time for enabling / disabling the dynamic power saving mode;

[0045] The second radio frame indicates that the second device is ready to serve the first device operating in the dynamic power saving mode, or is ready to serve the first device operating in the dynamic power saving mode.

[0046] In the above embodiment, by setting different response conditions for whether or not the second radio frame is received within the first time period, the time for enabling / disabling the dynamic power saving mode can be flexibly determined, thereby ensuring continuous and stable operation of the device while maximizing energy saving.

[0047] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes one or more of the following:

[0048] The dynamic power saving mode is enabled / disabled at the first time; wherein the first time is after the first device sends a third radio frame to the second device, and the third radio frame is used to confirm the second radio frame.

[0049] In the above embodiment, the accuracy of switching to the dynamic power saving mode is ensured by sending a confirmation frame to the second device. Through this confirmation mechanism, it can be ensured that the second device receives the correct instruction and takes corresponding actions.

[0050] In conjunction with some embodiments of the first aspect, in some embodiments, the first duration is carried in one or more of the following:

[0051] a first identification field of the first radio frame;

[0052] A second identification field of a fourth radio frame sent before sending the first radio frame; the fourth radio frame is used to associate or reassociate with the second device.

[0053] In the above embodiment, by carrying the first duration in the identification field of the first radio frame, accurate synchronization of communications between the first and second devices can be ensured, ensuring that the set maximum time limit is effectively applied. By embedding the first duration information in the fourth radio frame, this duration information can be effectively transmitted in advance during the device association or reassociation process, thereby preventing the decision to enable or disable dynamic power saving mode from being affected by untimely transmission or loss of duration information.

[0054] In combination with some embodiments of the first aspect, in some embodiments, when the first radio frame includes a first identification field and the fourth radio frame includes a second identification field, the first duration is determined based on the first identification field.

[0055] In the above embodiment, it can be ensured that the duration information is transmitted more clearly and accurately.

[0056] In conjunction with some embodiments of the first aspect, in some embodiments, after sending the first radio frame, the method further includes:

[0057] Receive a fifth wireless frame; the fifth wireless frame is used to confirm the first wireless frame; the first duration is calculated after receiving the physical layer protocol data unit PPDU containing the fifth wireless frame, or after receiving the PPDU containing the fifth wireless frame, after a signal extension time.

[0058] In the above embodiment, by associating the calculation of the first duration with the reception confirmation frame (fifth radio frame), the accuracy of the duration calculation is ensured and the duration calculation error caused by signal delay or interference is avoided.

[0059] In conjunction with some embodiments of the first aspect, in some embodiments, the first radio frame includes one or more of the following:

[0060] A third identification field, indicating whether the first device enables / disables the dynamic power saving mode;

[0061] The fourth identification field identifies the communication parameters of the first device in the dynamic power saving mode.

[0062] In the above embodiment, by setting multiple identification fields (such as the third identification field and the fourth identification field) in the first wireless frame, it can not only clearly indicate whether the first device enables or disables the dynamic power saving mode, but also further provide the communication parameters of the device in the dynamic power saving mode.

[0064] The first flag is set to a first parameter value, indicating that the first device enables the dynamic power saving mode;

[0065] The first flag is set to a second parameter value, indicating that the first device turns off the dynamic power saving mode.

[0066] In the above embodiment, by setting the first flag bit in the third flag field, it is possible to clearly indicate whether the first device enables or disables the dynamic power saving mode.

[0067] In conjunction with some embodiments of the first aspect, in some embodiments, the fourth identification field includes one or more of the following:

[0068] a first identification field, identifying a MAC fill time for the second device to send an initial control frame in the dynamic power saving mode; wherein the initial control frame is used to instruct the first device to switch from the first capability communication mode to the second capability communication mode;

[0069] The second identification field identifies a switching delay time required for the first device to switch from the second capability communication mode to the first capability communication mode.

[0070] In the above embodiment, by setting detailed switching information (such as the MAC padding time and switching delay duration of the initial control frame) in the fourth identification field, the first device can accurately indicate the relevant parameters for communication mode switching in dynamic power saving mode. In this way, the first device can effectively adjust its operating strategy based on this information, thereby reducing communication delays and system burden caused by frequent switching, and optimizing overall communication efficiency.

[0071] In conjunction with some embodiments of the first aspect, in some embodiments, the dynamic power saving mode supports the first device to switch between the first capability communication mode and the second capability communication mode;

[0116] Figure 1 It is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0117] like Figure 1 As shown, the communication system 100 includes a first device 101 and a second device 102 .

[0118] In some embodiments, the first device may be a station device (STA) or an access point device (AP). The second device may be an access point device or a station device. Optionally, the first device may be associated with the second device.

[0119] Optionally, the first device may also be referred to as a first communication device, and the second device may also be referred to as a second communication device.

[0120] In some embodiments, the first device 101 and the second device 102 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 is, for example, a mobile phone, a wearable device, an Internet of Things device that supports Wi-Fi communication, a car with Wi-Fi communication, a smart car, a tablet computer, a computer with wireless transceiver function, 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, but is not limited thereto.

[0121] Specifically, the first device 101 and the second device 102 may be terminal devices or network devices with a wireless fidelity (Wi-Fi) chip. Optionally, the first device 101 and the second device 102 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 support the next generation 802.11 protocol, but are not limited thereto.

[0122] In some embodiments, the first device 101 and the second device 102 can be access points for mobile terminals 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.

[0123] Optionally, in the embodiments of the present disclosure, the AP and STA may be devices that support multi-link communication. For example, they may be represented as an Access Point Multi-Link Device (AP MLD) and a Non-Access Point Multi-Link Device (Non-AP MLD), respectively. An AP MLD may represent an access point that supports multi-link communication functionality, and a non-AP MLD may represent a station that supports multi-link communication functionality. For example, in the embodiments of the present disclosure, the term "link" may represent a connection or a link; in various embodiments, the terms "connection" and "link" may be used interchangeably.

[0124] 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.

[0125] The following embodiments of the present disclosure can be applied to Figure 1 The communication system 100, or a portion thereof, is shown but is not limited thereto. Figure 1 The various entities shown are examples, and the communication system may include Figure 1 All or part of the subject, and may also include Figure 1 The number and form of other subjects are arbitrary, each subject can be physical or virtual, the connection relationship between the subjects is illustrative, the subjects can be connected or disconnected, and the connection can be in any way, which can be direct or indirect, wired or wireless.

[0126] The various embodiments of the present disclosure can be applied to wireless local area networks (WLANs), such as those using the 802.11 series of protocols. In a WLAN, a Basic Service Set (BSS) is a fundamental component of a WLAN. A BSS network consists of station devices with some association within a specific coverage area. One scenario of association is that stations communicate directly with each other in an ad hoc network, which is called an Independent Basic Service Set (IBSS). Another more common scenario is that in a BSS network, there is only one central station dedicated to managing the BSS, called an access point device, and all other STAs in the network are associated with it. Other stations in the BSS network that are not the central station are called terminals, also called non-AP STAs. Terminals and non-AP STAs are collectively referred to as STAs. When describing STAs, there is no need to distinguish between terminals and non-AP STAs. In the same BSS network, due to distance, transmission power, etc., a STA cannot detect other STAs that are farther away from it, and the two are each other's hidden nodes.

[0127] Figure 2 FIG. 1 is an interactive diagram of a communication method according to an embodiment of the present disclosure. Figure 2 As shown, the above method includes:

[0128] Step 201, the first device 101 sends a first wireless frame to the second device 102 associated with it; wherein, the first wireless frame identifies whether the first device 101 enables / disables a dynamic power saving mode, and / or enables / disables a first duration of the dynamic power saving mode; the first duration is used to indicate the maximum time limit for the second device to respond to the first wireless frame; accordingly, the second device 102 receives the first wireless frame sent by the first device 101.

[0129] Next-generation Wi-Fi technologies, such as Ultra High Reliability (UHR), aim to improve wireless LAN connection reliability, reduce latency, and lower device-level power consumption. Most devices supporting the UHR protocol support multi-link communication (MLD). Therefore, when UHR APs (APs supporting the UHR protocol) and UHR STAs (STAs supporting the UHR protocol) use multi-link communication for data transmission, power conservation mechanisms need to be further enhanced.

[0130] To further enhance power saving mechanisms, a dynamic power saving mode has been proposed. For example, a Mobile AP (mobile access point) or non-AP STA can operate in dynamic power saving mode. When a communication device operates in a lower capability mode, it supports an operating bandwidth of 20 MHz, only supports transceiver operations using a single spatial stream and a low-rate modulation and coding scheme (MCS), and only supports receiving specific control frames or management frames. Furthermore, a communication device operating in low capability mode can switch to a higher capability mode to complete frame exchange only after receiving a radio frame sent by its associated communication device. This radio frame is used to instruct the receiving end to switch from low capability mode to high capability mode in dynamic power saving mode. For example, this radio frame can be an initial control frame (ICF), which can be a multiple user request to send (MU-RTS) frame. After the current TXOP that receives the trigger frame ends, the communication device will switch back to the lower capability mode within a certain period of time to maintain an operating state with lower communication parameter values ​​and reduce device energy consumption.

[0131] Through the above-mentioned processing method, when the communication device maintains the dynamic power saving mode, the energy consumption of the communication device can be effectively reduced to a certain extent, but there are still many problems. For example, the UHR non-APSTA that supports the dynamic power saving mode instructs it to enable / disable the dynamic power saving mode during the association or reassociation process with the UHR AP; although this method can reduce signaling overhead and simplify the negotiation process, it has problems in flexibility. For example, once the UHR non-AP STA indicates to enable / disable the dynamic power saving mode when establishing an association or reassociation with the UHRAP, the UHR non-AP STA will remain in the state of enabling / disabling the dynamic power saving mode until it is disassociated from the UHR AP. In other words, even if the UHR non-AP STA may no longer need to enable / disable the dynamic power saving mode in some cases, it cannot dynamically adjust this mode because it has been fixed in the state after association and lacks the ability to adapt to dynamic needs.

[0132] To solve this problem, the embodiment of the present disclosure negotiates to enable / disable the dynamic power saving mode after the first device establishes an association with the second device. It has good flexibility and can be backward compatible with existing technologies, for example, it can coexist with the existing power saving mode (i.e., maintaining the dormant Doze state). Specifically, after the first device establishes an association with the second device, the first device sends a first wireless frame to the second device associated with it; wherein, the first wireless frame identifies that the first device enables / disables the dynamic power saving mode and enables / disables the first duration of the dynamic power saving mode; the first duration is used to indicate the maximum time limit for the second device to respond to the first wireless frame; accordingly, the second device receives the first wireless frame sent by the first device. The first device may be a UHR non-AP STA or a UHR AP; when the first device is a UHR non-AP STA, the second device is a UHR AP; when the first device is a UHR AP, the second device is a UHR non-AP STA; the first radio frame includes but is not limited to a dynamic power saving mode operation notification (DPS OperationNotification) frame; the first radio frame indicates that the first device enables (enters) the dynamic power saving mode, or the first radio frame indicates that the first device turns off the dynamic power saving mode; in addition, the first radio frame may also identify a first duration for enabling / disabling the dynamic power saving mode; the first duration is used to indicate the maximum time limit for the second device to respond to the first radio frame. The first duration may be a timeout duration (Timeout); for example, when the first device enables or disables the dynamic power saving mode, it specifies a timeout duration (first duration), which is used to indicate the maximum time limit for the second device to respond to the first radio frame, that is, to indicate the maximum time limit that the first device can allow the second device to respond to the first radio frame. For example, if the first duration is 10 milliseconds, it indicates that the first device allows the second device to respond to the first radio frame within 10 milliseconds. The second device is a device that supports the assisted dynamic power saving mode; supporting the assisted dynamic power saving mode means that after the first device enables the dynamic power saving mode, it supports sending an initial control frame to the first device to switch the first device from the low-capability communication mode to the high-capability communication mode.

[0133] In the embodiment of the present disclosure, after the first device establishes an association with the second device, the first device negotiates the enabling or disabling of the dynamic power saving mode, as well as the latest timeout period for enabling or disabling the dynamic power saving mode, by sending a first wireless frame. This effectively solves the problem of lack of flexibility in the prior art in indicating the enabling / disabling of the dynamic power saving mode by the device during the association process, because the embodiment of the present disclosure allows the first device to dynamically adjust the power saving mode according to actual needs, and is no longer fixed to the state after the association. At the same time, by introducing the concept of "first duration", it ensures that the turning on or off operation of the dynamic power saving mode is completed within a limited time, thereby improving the timeliness and efficiency of the operation. The embodiment of the present disclosure not only enhances the flexibility of the device, but is also compatible with the existing power saving mode, providing the device with a more efficient and dynamic energy management method, thereby reducing the energy consumption of the device and improving the overall performance of the system.

[0134] In some embodiments, the dynamic power saving mode supports the first device switching between a first capability communication mode and a second capability communication mode;

[0135] The first capability communication mode and the second capability communication mode include at least one identical working parameter, and a parameter value of at least one of the working parameters in the first capability communication mode is lower than that in the second capability communication mode.

[0136] Optionally, switching between the first capability communication mode and the second capability communication mode is performed, that is, switching from the first capability communication mode to the second capability communication mode, and switching from the second capability communication mode to the first capability communication mode.

The second capability communication mode may also be referred to as a high power mode, a high energy communication mode, a high capability communication mode, a high power communication mode, a higher capability communication mode, or a high power communication phase, etc., and the embodiments of the present disclosure do not limit these names.

[0138] Optionally, the parameter value of the communication parameter in the first capability communication mode is smaller than that in the second capability communication mode, which may mean that the communication capability of the communication device in the first capability communication mode is weaker than that in the second capability communication mode.

[0139] Optionally, the communication parameters corresponding to the first capability communication mode or the second capability communication mode may include but are not limited to channel bandwidth (Band Width, BW), supported modulation and coding scheme (Modulation and Coding Scheme, MCS), number of spatial streams (number of Spatial Stream, NSS), transmission rate, etc.

[0140] Optionally, in the first capability communication mode, the channel bandwidth supported by the device is 20 MHz (Mega Hertz) (ie, BW = 20 MHz), the number of SSs is 1 (ie, NSS = 1, single spatial stream), and the value of the MCS index is up to 5, that is, the value of the MCS index can be any value from 0 to 5, for example, the value of the MCS index is 5, etc. In the second capability communication mode, the channel bandwidth supported by the device can be greater than or equal to 20 MHz, for example, it can be any one or more of 40 MHz, 80 MHz, 160 MHz or 320 MHz, the number of SSs can be greater than or equal to 2, the MCS index can be greater than or equal to 5, etc., and no specific restrictions are made here.

[0141] In some embodiments, the first radio frame includes one or more of the following:

[0142] A third identification field, indicating whether the first device enables / disables the dynamic power saving mode;

[0143] The fourth identification field identifies the communication parameters of the first device in the dynamic power saving mode.

[0144] In the embodiment of the present disclosure, the frame structure of the first radio frame is shown in Table 1 below:

[0145] Table 1:

[0146]

[0147] Optionally, the first radio frame includes a category field (Category), a protected UHR action field (Protected UHRAction) or a UHR action field (UHR Action), a dialog token field (Dialog Token), a dynamic power saving mode control (DPSControl), and a dynamic power saving mode operation parameter field (DPS Operation Parameters). Among them, the third identification field may be a DPS Control field, and the fourth identification field may be a DPS Operation Parameters field.

[0148] In some embodiments, the third identification field includes a first identification bit;

[0149] The first flag is set to a first parameter value, indicating that the first device enables the dynamic power saving mode;

[0150] The first flag is set to a second parameter value, indicating that the first device turns off the dynamic power saving mode.

[0151] Optionally, the DPS Control domain includes a dynamic power saving mode enable (DPS Enable) flag, and the parameter value of the DPS Enable flag is set to "1", indicating that the first device enables the dynamic power saving mode; the parameter value of the DPS Enable flag is set to "0", indicating that the first device turns off the dynamic power saving mode.

[0152] In some embodiments, the fourth identification field includes one or more of the following:

[0153] a first identification field, identifying a MAC fill time for the second device to send an initial control frame in the dynamic power saving mode; wherein the initial control frame is used to instruct the first device to switch from the first capability communication mode to the second capability communication mode;

[0154] The second identification field identifies a switching delay time required for the first device to switch from the second capability communication mode to the first capability communication mode.

[0155] In the embodiment of the present disclosure, the fourth identification field may be a DPS Operation Parameters field, indicating the operating parameters of the first device in the dynamic power saving mode; for example, the first radio frame includes a DPS Operation Parameters field. The DPS Operation Parameters field includes one or more of the following:

[0156] The DPS Padding Delay field indicates the MAC padding time of the initial control frame required for the first device to switch from low-capability mode to high-capability mode;

[0157] The DPS Transaction Delay field indicates the transition delay time required for the first device to switch from the high-capability mode to the low-capability mode;

[0159] Step 202: The first device 101 determines a time to enable / disable the dynamic power saving mode according to a response result of the second device 102 to the first radio frame.

[0160] In an embodiment of the present disclosure, the first device determines the enabling or disabling time of the dynamic power saving mode based on the response result of the second device to the first wireless frame. This process determines the timing of turning on or off the dynamic power saving mode based on the feedback information of the second device, ensuring that the adjustment of the dynamic power saving mode can be dynamically decided according to actual communication needs. In this way, the first device can flexibly adjust the turning on or off of the dynamic power saving mode according to the actual communication environment, effectively avoiding energy waste caused by turning on the mode too early or too late. The embodiment of the present disclosure helps to improve the energy efficiency of the device and reduce unnecessary power consumption, while also enhancing the adaptability and flexibility of the device under different working conditions.

[0167] The communication method involved in the embodiment of the present disclosure may include at least one of steps 201 to 202. For example, step 201 may be implemented as an independent embodiment, step 202 may be implemented as an independent embodiment, and steps 201+202 may be implemented as independent embodiments.

[0168] In some embodiments, reference may be made to the steps and optional implementation methods of other embodiments recorded before or after the description corresponding to this embodiment, as well as other related parts in the description, which will not be repeated here.

[0169] Figure 3 FIG. 1 is an interactive diagram of a communication method according to an embodiment of the present disclosure. Figure 3 As shown, the embodiment of the present disclosure relates to a communication method, which includes:

[0170] Step 301, the first device 101 sends a first wireless frame to the second device 102 associated with it; wherein, the first wireless frame identifies whether the first device 101 enables / disables the dynamic power saving mode, and / or enables / disables the first duration of the dynamic power saving mode; the first duration is used to indicate the maximum time limit for the second device to respond to the first wireless frame.

[0171] In an embodiment of the present disclosure, a first device sends a first wireless frame to a second device associated with it, and the frame is used to identify whether the first device enables or disables a dynamic power saving mode, and / or the latest first duration for enabling / disabling the dynamic power saving mode. After receiving the wireless frame, the second device can understand the power saving mode status of the first device based on the information indicated in the frame. This process helps the devices to work together in the dynamic power saving mode and achieve a balance between energy efficiency optimization and communication performance. The first device can be a UHR non-AP STA or a UHR AP; when the first device is a UHR non-AP STA, the second device is a UHR AP; when the first device is a UHR AP, the second device is a UHR non-APSTA.

[0172] In step 302 , the second device 102 sends a fifth radio frame, where the fifth radio frame is used to confirm the first radio frame. Correspondingly, the first device 101 receives the fifth radio frame sent by the second device 102 .

[0173] In the disclosed embodiment, after receiving the first radio frame, the second device sends a fifth radio frame to the first device. The fifth radio frame is used to confirm the first radio frame. The fifth radio frame includes but is not limited to an acknowledgment (ACK) frame. Acknowledging the first radio frame with the fifth radio frame ensures the reliability of communication information between the first and second devices, reduces the risk of misunderstanding or loss, and thus improves communication efficiency and system stability.

[0174] In step 303, the second device 102 sends a second wireless frame within the first time period, and the second wireless frame indicates that the second device 102 is ready to serve the first device 101 operating in the dynamic power saving mode, or is ready to serve the first device 101 operating in the dynamic power saving mode; accordingly, the first device 101 receives the second wireless frame sent by the second device 102.

[0175] In an embodiment of the present disclosure, after sending the fifth radio frame, if the second device is ready to serve the first device operating in dynamic power saving mode or is ready to serve the first device operating in dynamic power saving mode disabled, the second device sends a second radio frame within a first duration to confirm whether it can effectively communicate with the first device in the current dynamic power saving mode. For example, if the first device has dynamic power saving mode enabled, the second device sends the second radio frame to indicate that it supports communication with the first device in dynamic power saving mode enabled; conversely, if the first device has dynamic power saving mode disabled, the second device sends the second radio frame to indicate that it supports communication with the first device in dynamic power saving mode disabled. By sending the second radio frame, the second device can flexibly adjust its communication strategy based on the dynamic power saving mode status of the first device, thereby achieving more efficient communication. In particular, in UHR non-AP STA and UHR AP scenarios, the second device can confirm whether it can continue to effectively communicate with the first device, reducing communication conflicts and unnecessary energy consumption, and improving the flexibility of the device in power saving mode and the stability of the system. Optionally, the frame content of the second radio frame can be the same as the frame content of the first radio frame.

[0176] In some embodiments, the first duration is carried in one or more of the following:

[0177] a first identification field of the first radio frame;

[0178] A second identification field of a fourth radio frame sent before sending the first radio frame; the fourth radio frame is used to associate or reassociate with the second device.

[0179] In an embodiment of the present disclosure, the maximum value of the first duration can be indicated by a first identification field in the first radio frame, or by a second identification field carried in an association request frame or a reassociation request frame; wherein the first identification field and the second identification field include but are not limited to a dynamic power saving mode timeout (DPS Transaction Timeout). For example, in the process of establishing an association or reassociation with a UHR AP, the association request frame or the reassociation request frame may include a dynamic power saving mode operation parameters (DPS Operation Parameters) field, which may be included in an ultra-high reliability operation element (UHR Operation element) or a basic multi-link element (Basic Multi-Link element), thereby indicating the duration of the DPS Transaction Timeout. In this way, the second device can obtain duration information related to the dynamic power saving mode of the first device in different radio frames. This flexible duration indication method helps to improve negotiation efficiency during communication and reduce signaling overhead.

[0180] In some embodiments, when the first radio frame includes a first identification field and the fourth radio frame includes a second identification field, the first duration is determined according to a most recent identification field of the two.

[0181] In an embodiment of the present disclosure, when the first radio frame includes a first identification field and a fourth radio frame sent before the first radio frame includes a second identification field, the first duration is determined based on the first identification field of the first radio frame most recently received by the second device. The first identification field and the second identification field both include a DPS TransactionTimeout field.

[0182] In step 304, after receiving the second radio frame sent by the second device within the first duration, the first device 101 sends a third radio frame to the second wireless device, where the third radio frame is used to confirm the second radio frame. Correspondingly, the second device 102 receives the third radio frame sent by the first device 101. The first duration starts after the first device 101 receives the PPDU containing the fifth line frame sent by the second device 102, or after the first device 101 receives the PPDU containing the fifth line frame sent by the second device 102, and then the signal extension time begins. For example, the second duration starts after the first device 101 receives the PPDU containing the third fifth line frame sent by the second device 102 [+sigExt].

[0183] In the disclosed embodiment, after receiving the second radio frame sent by the second device, the first device sends a third radio frame to the second device after a short inter-flush interval (SIFS). The third radio frame is used to confirm the second radio frame and may be an ACK frame. By sending an acknowledgment frame, the first device can ensure smooth communication with the second device. This confirmation mechanism allows the system to more reliably synchronize the status of each device, ensuring a clear and unambiguous switching process for dynamic power saving mode, thereby improving communication stability and reliability.

[0184] Step 305 , the first device 101 enables / disables the dynamic power saving mode at the first time; wherein, the first time is after the first device 101 sends a third radio frame to the second device 102 .

[0185] In the embodiment of the present disclosure, the first device enables / disables the dynamic power saving mode after sending the third wireless frame to the second device. That is, if the first device receives the second wireless frame sent by the second device within the first time period, the first device executes the enable / disable dynamic power saving mode identified by the first wireless frame after sending the second wireless frame. This method ensures that the switching operation of the dynamic power saving mode is performed after confirming that the communication link is normal, thereby avoiding inconsistent states or unnecessary mode switching due to incomplete or erroneous information transmission. Through this mechanism, the first device can flexibly adjust the working mode after reliable signal confirmation, effectively improving the efficiency of power consumption management and ensuring the stability and flexibility of the device.

[0186] The communication method involved in the embodiments of the present disclosure may include at least one of steps 301 to 305. For example, step 301 can be implemented as an independent embodiment, step 303 can be implemented as an independent embodiment, step 305 can be implemented as an independent embodiment, steps 301+302 can be implemented as an independent embodiment, steps 303+304 can be implemented as an independent embodiment, and steps 304+305 can be implemented as an independent embodiment.

[0187] In some embodiments, reference may be made to the steps and optional implementation methods of other embodiments recorded before or after the description corresponding to this embodiment, as well as other related parts in the description, which will not be repeated here.

[0188] Figure 4 FIG. 1 is an interactive diagram of a communication method according to an embodiment of the present disclosure. Figure 4 As shown, the embodiment of the present disclosure relates to a communication method, which includes:

[0189] Step 401, the first device 101 sends a first wireless frame to the second device 102 associated with it; wherein, the first wireless frame identifies whether the first device 101 enables / disables a dynamic power saving mode, and / or enables / disables a first duration of the dynamic power saving mode; the first duration is used to indicate the maximum time limit for the second device to respond to the first wireless frame; accordingly, the second device 102 receives the first wireless frame sent by the first device 101.

[0190] In an embodiment of the present disclosure, a first device sends a first wireless frame to a second device associated with it, and the frame is used to identify whether the first device enables or disables a dynamic power saving mode, and the latest first duration of the dynamic power saving mode. After receiving the wireless frame, the second device can understand the power saving mode status of the first device based on the information indicated in the frame. This process helps the devices to work together in the dynamic power saving mode and achieve a balance between energy efficiency optimization and communication performance. The first device can be a UHR non-AP STA or a UHR AP; when the first device is a UHR non-AP STA, the second device is a UHR AP; when the first device is a UHR AP, the second device is a UHR non-AP STA.

[0191] In step 402 , the second device 102 sends a fifth radio frame, where the fifth radio frame is used to confirm the first radio frame. Correspondingly, the first device 101 receives the fifth radio frame sent by the second device 102 .

[0192] In this disclosed embodiment, after receiving the first radio frame, the second device sends a fifth radio frame to the first device. The fifth radio frame is used to confirm the first radio frame. The fifth radio frame includes but is not limited to an ACK frame. Acknowledging the first radio frame with the fifth radio frame ensures the reliability of communication information between the first and second devices, reduces the risk of misunderstanding or loss, and thus improves communication efficiency and system stability.

[0193] In step 403, the first device 101 determines a second time to enable / disable the dynamic power saving mode. The second time is the time when the first duration expires and begins after the first device 101 receives the PPDU containing the fifth line frame from the second device 102, or after the first device 101 receives the PPDU containing the fifth line frame from the second device 102, and then after the signal extension time has elapsed. For example, the second time begins after the first device 101 receives the PPDU containing the third fifth line frame from the second device 102 [+sigExt].

[0194] In the disclosed embodiment, if the first device does not receive the second radio frame sent by the second device within the first duration, the first device determines a second time to enable / disable the dynamic power saving mode. This means that even if the second device does not send the second radio frame to the first device within the first duration, the first device can still determine a time to enable / disable the dynamic power saving mode based on this behavior of the second device, thereby ensuring efficient communication and optimizing device energy consumption.

[0195] In some embodiments, the first duration is carried in one or more of the following:

[0196] a first identification field of the first radio frame;

[0197] A second identification field of a fourth radio frame sent before sending the first radio frame; the fourth radio frame is used to associate or reassociate with the second device.

[0198] In an embodiment of the present disclosure, the maximum value of the first duration can be indicated by a first identification field in the first radio frame, or by a second identification field carried in an association request frame or a reassociation request frame; wherein the first identification field and the second identification field include but are not limited to a dynamic power saving mode timeout (DPS Transaction Timeout). For example, when a UHR non-AP STA is establishing an association or reassociation with a UHR AP, the association request frame or the reassociation request frame may include a dynamic power saving mode operation parameters (DPS Operation Parameters) field, which may be included in an ultra-high reliability operation element (UHR Operation element) or a basic multi-link element (Basic Multi-Link elemen), thereby indicating the duration of the DPS Transaction Timeout. In this way, the second device can obtain duration information related to the dynamic power saving mode of the first device in different radio frames. This flexible duration indication method helps to improve negotiation efficiency during communication and reduce signaling overhead.

[0199] In some embodiments, when the first radio frame includes a first identification field and the fourth radio frame includes a second identification field, the first duration is determined according to the first identification field.

[0200] In an embodiment of the present disclosure, when the first radio frame includes a first identification field and a fourth radio frame sent before the first radio frame includes a second identification field, the first duration is determined based on the first identification field of the first radio frame most recently received by the second device. The first identification field and the second identification field both include a DPS TransactionTimeout field.

[0201] In some embodiments, the first duration is calculated from the time the PPDU containing the fifth radio frame is received, or is calculated from the time the signal extension time has passed after the PPDU containing the fifth radio frame is received.

[0202] In the embodiment of the present disclosure, the first duration is calculated from the time the physical layer protocol data unit (PPDU) containing the fifth radio frame is received, or from the time the signal extension time (SigExt) is passed after the PPDU is received. This setting ensures that the first device can take into account the influence of signal delay and signal extension time when performing dynamic power saving mode switching, thereby improving the accuracy and reliability of time calculation. In this way, the first device can more accurately determine when to switch modes, effectively avoiding communication interruptions or improper power consumption management caused by inaccurate timing, thereby optimizing the performance and energy efficiency of the device.

[0203] Step 404: The first device 101 enables / disables the dynamic power saving mode at the second time; wherein the second time is after the first duration ends.

[0204] In an embodiment of the present disclosure, if the first device does not receive the second radio frame sent by the second device within the first duration, the first device enables / disables the dynamic power saving mode after the first duration expires. For example, after the first radio frame sends the first radio frame to the second device that supports sending initial control frames in dynamic power saving mode, if the second device does not promptly send the second radio frame at the latest frame exchange time specified by the first device, the first device automatically enables / disables the dynamic power saving mode after the latest frame exchange time arrives. By automatically enabling or disabling the dynamic power saving mode after the latest frame exchange time when the first device does not receive the second radio frame sent by the second device, the problem of untimely dynamic power saving mode switching due to communication delays or frame loss can be effectively avoided. This approach improves the autonomy and flexibility of devices during communication, ensures that dynamic power saving mode management is completed within the specified time, and thus optimizes power consumption control and device energy efficiency. It is understood that the first device enables / disables the dynamic power saving mode regardless of whether the first device receives the second radio frame within the first duration or the DPSTransaction Timeout indication time arrives.

[0205] The communication method involved in the embodiments of the present disclosure may include at least one of steps 401 to 404. For example, step 401 can be implemented as an independent embodiment, step 403 can be implemented as an independent embodiment, step 404 can be implemented as an independent embodiment, steps 401+402 can be implemented as an independent embodiment, steps 403+404 can be implemented as an independent embodiment, and steps 304+305 can be implemented as an independent embodiment.

[0206] In some embodiments, reference may be made to the steps and optional implementation methods of other embodiments recorded before or after the description corresponding to this embodiment, as well as other related parts in the description, which will not be repeated here.

[0207] Figure 5 It is a flowchart of a communication method according to an embodiment of the present disclosure.

[0208] like Figure 5 As shown, the above method can be applied to the first device 101, and the above method includes:

[0209] Step 501: Send a first wireless frame to a second device associated with it; wherein, the first wireless frame identifies whether the first device enables / disables a dynamic power saving mode, and / or enables / disables a first duration of the dynamic power saving mode; the first duration is used to indicate the maximum time limit for the second device to respond to the first wireless frame.

[0210] Step 502: Determine a time to enable / disable the dynamic power saving mode according to a response result of the second device to the first radio frame.

[0211] Optionally, in the embodiment of the present disclosure, determining the time to enable the dynamic power saving mode according to the response result of the second device to the first radio frame includes one or more of the following:
