[0041] This disclosure presents a communication method, communication device, and communication system.

[0042] In a first aspect, embodiments of this disclosure provide a communication method applied to a first device, the method comprising:

[0043] In dynamic power saving mode, a first wireless frame sent by at least one second device is received; wherein, the first wireless frame identifies whether the second device supports the dynamic power saving mode, or whether the second device supports sending a second wireless frame; the second wireless frame is used to instruct the device in dynamic power saving mode to switch communication mode after receiving the second wireless frame.

[0044] Based on the first wireless frame, maintain or disable the dynamic power saving mode.

[0045] In the above embodiments, by determining whether to maintain or disable the power-saving mode based on the received first wireless frame information in dynamic power-saving mode, efficient resource management and energy saving are achieved, avoiding unnecessary energy waste. This method can improve the response speed and communication stability of the device in variable communication environments, while effectively reducing the time for device mode switching, thereby improving communication efficiency and overall system performance.

[0046] In conjunction with some embodiments of the first aspect, in some embodiments, maintaining or disabling the dynamic power-saving mode based on the first wireless frame includes one or more of the following:

[0047] The second device that sends the first wireless frame is a first-type device, which disables the dynamic power saving mode; wherein, the first-type device is a device that does not support the dynamic power saving mode;

[0048] The second device that sends the first wireless frame is a second type of device, and the dynamic power saving mode is turned off; wherein, the second type of device is a device that does not support sending the second wireless frame;

[0049] The second device that sends the first wireless frame is a third type of device that maintains the dynamic power-saving mode; wherein, the third type of device is a device that supports sending the second wireless frame.

[0050] In the above embodiments, the power-saving mode of the device is flexibly adjusted according to the received first wireless frame indication information. Specifically, the device can decide whether to maintain or disable the dynamic power-saving mode based on the different types of second devices. In this way, by identifying the device type and making corresponding adjustments, more intelligent and efficient resource management is achieved, unnecessary power consumption is avoided, and the response efficiency and stability of the device are improved in various communication scenarios.

[0051] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0052] After both the first type of device and the second type of device are disconnected from the first device, the dynamic power saving mode is activated.

[0053] In the above embodiments, after the first type of device and the second type of device are de-associated with the first device, a dynamic power-saving mode is automatically activated. By intelligently judging the device association status, it ensures that the device can enter the power-saving mode in a timely manner when it does not need to maintain high power consumption, thereby effectively saving energy.

[0054] In conjunction with some embodiments of the first aspect, in some embodiments, turning off the dynamic power-saving mode includes one or more of the following:

[0055] A third wireless frame is sent to the second device, and the dynamic power saving mode is turned off; wherein, the second device is a first type of device, and the first wireless frame indicates that the second device does not support the dynamic power saving mode; the third wireless frame is a response frame to the first wireless frame;

[0056] A fourth wireless frame is sent to the second device, the fourth wireless frame indicating that the first device has turned off the dynamic power saving mode; wherein, the second device is a second type of device, and the first wireless frame indicates that the second device does not support sending the second wireless frame; the fourth wireless frame is a response frame to the first wireless frame;

[0057] A fifth wireless frame is identified, which indicates that the first device has turned off the dynamic power saving mode; the fifth wireless frame is then broadcast.

[0058] In the above embodiments, intelligent identification and response to different types of devices make the dynamic power-saving mode shutdown more flexible and efficient. Different processing methods for different device types help improve system energy efficiency and communication stability, while ensuring timely adjustments under different operating conditions, reducing unnecessary power consumption, and thus optimizing resource utilization.

[0059] In conjunction with some embodiments of the first aspect, in some embodiments, maintaining the dynamic power-saving mode includes:

[0060] Send a sixth wireless frame to the second device while maintaining the dynamic power saving mode; wherein the second device is a third type of device, and the first wireless frame identifies that the second device supports sending the second wireless frame; the sixth wireless frame is a response frame to the first wireless frame.

[0061] In the above embodiments, when the second device is a third type of device and the second device supports sending a second wireless frame, the first device maintains a dynamic power-saving mode and sends a sixth wireless frame to the second device, thereby achieving efficient resource management and energy saving and avoiding unnecessary energy waste.

[0062] In conjunction with some embodiments of the first aspect, in some embodiments, after transmitting the third radio frame, the method further includes one or more of the following:

[0063] If the second device fails to associate with the first device, and all other devices associated with the first device support the dynamic power saving mode, a seventh wireless frame is determined, the seventh wireless frame indicating that the first device has enabled the dynamic power saving mode; the seventh wireless frame is then broadcast.

[0064] If the first device does not receive an association request frame sent by the second device, and all other devices associated with the first device support the dynamic power saving mode, an eighth wireless frame is determined, the eighth wireless frame indicating that the first device has enabled the dynamic power saving mode; the eighth wireless frame is then broadcast.

[0065] In the above embodiments, by automatically activating the dynamic power-saving mode and broadcasting relevant status information under specific conditions (such as association failure or failure to receive an association request frame), the energy-saving efficiency of the device can be improved and unnecessary energy consumption reduced. Furthermore, the broadcast mechanism ensures that other devices are promptly informed of the activation status of the dynamic power-saving mode, thereby facilitating state coordination and resource optimization among devices in the network.

[0066] In conjunction with some embodiments of the first aspect, in some embodiments, before receiving the first wireless frame transmitted by the second device, the method further includes:

[0067] A ninth wireless frame is determined; the ninth wireless frame includes first identification information, which identifies whether the first device supports the dynamic power saving mode.

[0068] The ninth wireless frame is transmitted.

[0069] In the above embodiments, before receiving the first wireless frame sent by the second device, the first device sends a ninth wireless frame to inform the network or other devices whether it supports dynamic power saving mode, thereby enabling the second device to make a corresponding decision based on the support status of the first device.

[0070] In conjunction with some embodiments of the first aspect, in some embodiments, the first identification information is set to a first parameter value, indicating that the first device supports the dynamic power saving mode;

[0071] The first identification information is set to the second parameter value, indicating that the first device does not support the dynamic power saving mode.

[0072] In the above embodiments, different parameter values ​​are set to indicate whether dynamic power saving mode is supported. In this way, the second device can more accurately understand the capabilities of the first device, avoiding unnecessary power saving mode switching operations when dynamic power saving mode is not supported, thereby reducing communication overhead and energy consumption.

[0073] In conjunction with some embodiments of the first aspect, in some embodiments, the ninth wireless frame further includes second identification information, the second identification information indicating that the first device has enabled or disabled the dynamic power saving mode.

[0074] In the above embodiments, the first device explicitly indicates its current dynamic power-saving mode status (on or off) by adding second identification information to the ninth wireless frame. This allows the second device to understand the power-saving status of the first device in real time and adjust its communication strategy or behavior accordingly, ensuring efficient collaboration and resource conservation between devices.

[0075] In conjunction with some embodiments of the first aspect, in some embodiments, when the first identification information is set to a first parameter value, the second identification information is set to a third parameter value, indicating that the first device has enabled the dynamic power saving mode;

[0076] The second identification information is set to the fourth parameter value, indicating that the first device turns off the dynamic power saving mode.

[0077] In the above embodiments, the first device can transmit specific information about the dynamic power-saving mode in the ninth wireless frame by setting different parameter values. The combined use of the first identification information and the second identification information can clearly indicate whether the first device turns the power-saving mode on or off. In this way, the second device can make corresponding adjustments based on the power-saving status of the first device, further improving communication efficiency and reducing unnecessary energy consumption.

[0078] In conjunction with some embodiments of the first aspect, in some embodiments, the ninth wireless frame further includes third identification information, which identifies the communication parameters of the first device in the dynamic power-saving mode.

[0079] In the above embodiments, by adding third identification information to the ninth wireless frame, the first device can transmit its communication parameters in dynamic power-saving mode, thereby enabling the second device communicating with it to make corresponding adjustments based on these parameters.

[0080] In conjunction with some embodiments of the first aspect, 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;

[0081] The first capability communication mode and the second capability communication mode include at least one identical operating parameter, and the parameter value of at least one of the operating parameters is lower in the first capability communication mode than in the second capability communication mode.

[0082] In the above embodiments, by switching to the first capability communication mode, the first device can communicate with lower power consumption, thereby saving energy and maximizing battery life when higher communication performance is not required. Simultaneously, the differentiated settings (such as differences in parameter values) between the first and second capability communication modes further optimize the utilization efficiency of communication resources. This switching mechanism also ensures that the device can maintain basic communication capabilities in low-power mode, thereby improving the reliability and stability of the overall communication system, especially in scenarios with a large number of devices or where energy saving is required, demonstrating a significant optimization effect.

AP MLD can represent an access point that supports multi-link communication functions, and non-AP MLD can represent a site that supports multi-link communication functions. For example, in this embodiment of the disclosure, link can represent connection or link; in various embodiments, connection and link can be interchanged.

[0141] 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.

[0142] 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.

[0143] 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.

[0144] Figure 2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, the method includes:

[0145] Step 201, the second device 102 sends a first wireless frame; wherein, the first wireless frame identifies whether the second device 102 supports the dynamic power saving mode, or whether the second device 102 supports sending a second wireless frame; the second wireless frame is used to instruct the device in the dynamic power saving mode to switch communication modes after receiving the second wireless frame.

[0146] Next-generation Wi-Fi technologies, such as Ultra High Reliability (UHR), aim to improve the reliability of wireless LAN connections, reduce latency, and lower device-level power consumption. Since most devices supporting the UHR protocol are multi-link communication devices (MLD devices), power-saving mechanisms need further enhancement when UHR APs (Access Points) and UHR STAs (Standard Stations) use multi-link communication for data transmission.

[0147] Currently, to further enhance power saving mechanisms, a dynamic power saving mode has been proposed. For example, Mobile APs (Mobile Access Points) or non-AP STAs can operate in dynamic power saving mode. When the communication device operates in a lower capability mode, it supports a working bandwidth of 20MHz, and only supports single spatial stream and low-rate MCS (Modulation and Coding Scheme) for transmission and reception operations, and only supports receiving specific control frames or management frames.

[0148] However, enabling or disabling dynamic power saving mode on a non-AP STA during the association process can cause some problems. On one hand, if a non-AP STA enables dynamic power saving mode during association, it may conflict with the Target Wake Time (TWT) mechanism and periodic power saving modes. For example, the TWT mechanism requires the device to be active at a predetermined wake-up time, but dynamic power saving mode may fail to respond to TWT requirements in a timely manner due to switching delays. On the other hand, if a non-AP STA disables dynamic power saving mode, the device will always operate in a single power mode, losing the ability to dynamically adjust the power mode, thus reducing power saving efficiency.

[0149] In this embodiment, the second device includes, but is not limited to, an ultra-high reliability multi-link STA (UHR non-AP STA), a legacy multi-link STA, and a pre-UHR non-AP STA. The first radio frame includes, but is not limited to, a probe request frame, an association request frame, and a reassociation response frame. The second device sends the first radio frame, which identifies whether the second device supports the dynamic power-saving mode or whether the second device supports sending a second radio frame. The second radio frame is used to instruct the device in dynamic power-saving mode to switch communication modes after receiving the second radio frame. For example, after receiving the second radio frame sent by the second device, the first device with dynamic power-saving mode enabled switches from a low-capacity communication mode to a high-capacity communication mode to complete frame exchange. The second radio frame includes, but is not limited to, the initial control frame (ICF); the initial control frame includes, but is not limited to, the multiple user request to send trigger frame (MU-RTS Trigger frame) and the buffer status report poll trigger frame (BSRP Trigger frame).

[0150] In this embodiment, through a first radio frame, a non-AP STA can indicate to the associated device during the association process whether it supports dynamic power saving mode or whether it supports sending a second radio frame. This effectively avoids conflicts between dynamic power saving mode and other power saving mechanisms (such as TWT mechanism and periodic power saving mode). Specifically, when a non-AP STA explicitly indicates support for dynamic power saving mode, the associated device can optimize its configuration for this mode to avoid conflicts with the scheduling logic of other mechanisms. Conversely, when a non-AP STA indicates that it does not support dynamic power saving mode, the associated device can directly select other power saving mechanisms to avoid interference from dynamic power saving mode. This capability identification mechanism is completed at the initial stage of communication establishment, ensuring the coordination between power saving modes, effectively improving the power consumption management efficiency and flexibility of the device, and avoiding communication failures or resource waste caused by conflicts in power saving mechanisms.

[0151] 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;

[0152] The first capability communication mode and the second capability communication mode include at least one identical operating parameter, and the parameter value of at least one of the operating parameters is lower in the first capability communication mode than in the second capability communication mode.

[0153] Optionally, switching can be performed between a first capability communication mode and a second capability communication mode, i.e., 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.

[0154] Optionally, the first capability communication mode may also be referred to as a first power mode, low-energy communication mode, low-capability communication mode, low-power communication mode, lower capability communication mode, eavesdropping mode, or low-power communication phase, etc., and this disclosure does not limit the name. The second capability communication mode may also be referred to as a high-power mode, high-energy communication mode, high-capability communication mode, high-power communication mode, higher capability communication mode, or high-power communication phase, etc., and this disclosure does not limit the name.

[0155] Optionally, the parameter value of the communication parameter is less than that of the second capability communication mode in the first capability communication mode, which can 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.

[0156] 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 (BW), supported modulation and coding scheme (MCS), number of spatial streams (NSS), transmission rate, etc.

[0157] Optionally, in the first capability communication mode, the device supports a channel bandwidth of 20MHz (Mega Hertz) (i.e., BW = 20MHz), the number of SSs is 1 (i.e., NSS = 1, single spatial stream), and the maximum value of the MCS index is 5, meaning the MCS index value can be any value from 0 to 5, for example, an MCS index value of 5. In the second capability communication mode, the device supports a channel bandwidth greater than or equal to 20MHz, for example, any one or more of 40MHz, 80MHz, 160MHz, or 320MHz, the number of SSs can be greater than or equal to 2, the MCS index can be greater than or equal to 5, etc., without specific limitations.

[0158] Step 202: The first device 101 maintains or disables the dynamic power saving mode according to the first wireless frame.

[0159] In some embodiments, the first device 101 includes, but is not limited to, a mobile access point (Mobile AP).

[0160] In Mobile AP scenarios, enabling or disabling the dynamic power-saving mode of the Mobile AP also presents some issues. Firstly, because Legacy non-AP STAs or pre-UHR non-AP STAs (hereinafter referred to as Legacy devices) typically adhere to earlier standards, they do not support the parsing or negotiation logic for dynamic power-saving mode. If the Mobile AP enters dynamic power-saving mode, Legacy devices may be unable to recognize and adapt to it, leading to communication failures between devices. Secondly, if the Mobile AP disables dynamic power-saving mode during the association process, it needs to always operate in high-power mode to ensure communication quality. While this avoids compatibility issues with Legacy devices, it significantly increases the power consumption of the Mobile AP, violating the design goal of low-power optimization.

[0161] Optionally, when the first device supports dynamic power saving mode, dynamic power saving mode is enabled by default. This means that the Mobile AP will preferentially choose to operate in dynamic power saving mode unless it receives special instructions or encounters specific conditions. The enabled state of dynamic power saving mode enables the Mobile AP to achieve low power consumption operation by default.

[0162] In this embodiment of the disclosure, if the first device supports dynamic power saving mode, the first device is in a state where dynamic power saving is enabled before receiving the first wireless frame. Then, after receiving the first wireless frame sent by the second device, the first device performs any one of the following response operations:

[0163] Scenario 1: The first device turns off the dynamic power saving mode based on the first wireless frame;

[0164] In some embodiments, disabling the dynamic power-saving mode includes at least one of the following:

[0165] The second device that sends the first wireless frame is a first-type device, and the dynamic power saving mode is turned off; wherein, the first-type device is a device that does not support the dynamic power saving mode;

[0166] The second device that sends the first wireless frame is a second type of device, and the dynamic power saving mode is turned off; wherein, the second type of device is a device that does not support sending the second wireless frame;

[0167] In this embodiment of the disclosure, if the second device sending the first wireless frame is a Legacy device or a UHR non-AP STA that does not support dynamic power saving mode, the dynamic power saving mode is turned off.

[0168] Optionally, the first device can determine the type of the second device by parsing the first radio frame; wherein, the type of the second device may or may not be carried in a certain identifier bit of the first radio frame, and no specific restriction is made here.

[0169] For example, if a Mobile AP receives a Probe Request frame from at least one Legacy device that does not support the dynamic power-saving mode, the Mobile AP disables the dynamic power-saving mode. In this case, to ensure that the Mobile AP and the Legacy device can establish a connection and complete communication normally, the Mobile AP disables the dynamic power-saving mode and falls back to a traditional communication mode compatible with the Legacy device. This disabling operation not only avoids connection failures caused by the incompatibility of the dynamic power-saving mode, but also ensures that the Mobile AP can flexibly adapt to the capability requirements of different devices, thereby improving system compatibility and stability.

[0170] In this embodiment of the disclosure, when the second device sending the first radio frame is a UHR non-AP STA, the dynamic power saving mode is disabled. For example, if the Mobile AP receives at least one Probe Request frame or (Re)Association Request frame from a UHR non-AP STA, but the UHR non-AP STA does not support sending the second radio frame, the Mobile AP disables the dynamic power saving mode to avoid communication failures or cooperation problems caused by enabling incompatible dynamic power saving mechanisms in subsequent communications. After disabling the dynamic power saving mode, the Mobile AP can transmit data with the UHR non-AP STA using traditional communication methods, thereby ensuring normal communication and system stability. The UHR non-AP STA indicates whether it supports sending the second radio frame through the Dynamic Power Saving Mode Assist Support (DPS Assist Support) flag bit of the first radio frame. For example, in the above case, the parameter value of the DPS Assist Support flag bit is set to "0".

[0171] Scenario 2: The first device maintains the dynamic power saving mode according to the first wireless frame.

[0172] In some embodiments, the second device that sends the first wireless frame is a third type of device that maintains the dynamic power-saving mode; wherein, the third type of device is a device that supports sending the second wireless frame.

[0173] In this embodiment of the disclosure, the second device transmitting the first radio frame is a UHR non-AP STA that supports transmitting the second radio frame, maintaining the dynamic power-saving mode. In this case, since the second device supports the UHR protocol and supports transmitting the second radio frame, the first device can continue to maintain the dynamic power-saving mode.

[0174] Scenario 3: The first device activates the dynamic power saving mode based on the first wireless frame.

[0175] In some embodiments, the dynamic power saving mode is activated after both the first type of device and the second type of device are decoupled from the first device.

[0176] Optionally, the dynamic power-saving mode is activated after both the first type of device and the second type of device in the second device that sent the first wireless frame are de-associated with the first device.

[0177] In this embodiment of the disclosure, the first type of device is a Legacy device, and the second device is a UHR non-AP STA that does not support transmitting the second radio frame. Therefore, after both the first type of device and the second type of device are de-associated with the first device, the remaining devices associated with the first device are all UHR non-AP STAs that support transmitting the second radio frame. Thus, the first device can then re-enable the dynamic power-saving mode to further reduce energy consumption and improve the device's power-saving effect.

[0186] Figure 3 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 3, the embodiments of the present disclosure relate to a communication method, which includes:

[0187] Step 301, the second device 102 sends a first wireless frame; wherein, the first wireless frame identifies whether the second device 102 supports the dynamic power saving mode, or whether the second device 102 supports sending a second wireless frame; the second wireless frame is used to instruct the device in the dynamic power saving mode to switch communication modes after receiving the second wireless frame.

[0188] In this embodiment of the disclosure, the second device sends a first wireless frame, the first wireless frame identifying whether the second device supports the dynamic power saving mode, or whether the second device supports sending a second wireless frame; wherein, the second device includes, but is not limited to, a first type of device, a second type of device, and a third type of device.

[0189] Step 302: If the first wireless frame indicates that the second device 102 that sent the first wireless frame is a first type of device, the first device 101 turns off the dynamic power saving mode.

[0190] In this embodiment of the disclosure, if the first radio frame indicates that the second device sending the first radio frame is a Legacy device or a UHR non-AP STA that does not support dynamic power saving mode, the dynamic power saving mode is turned off.

[0191] In step 303, the first device 101 sends a third wireless frame; correspondingly, the second device 102 receives the third wireless frame sent by the first device 101.

[0192] In this embodiment of the disclosure, if the second device is a legacy device or a UHR non-AP STA that does not support dynamic power saving mode, the Mobile AP sends a third radio frame after disabling dynamic power saving mode.

[0195] The fifth radio frame was broadcast.

[0196] In this embodiment of the disclosure, after the Mobile AP establishes an association with a Legacy device or a UHR non-AP STA that does not support dynamic power saving mode, the Mobile AP broadcasts the information indicating that dynamic power saving mode is disabled. For example, the Mobile AP determines and sends a Beacon frame; the Beacon frame carries an Ultra-High Reliability Operation Parameters field; the UHR Operation Parameters field includes a Dynamic Power Saving Mode Enable (DPS Enable) flag, and the parameter value of the DPS Enable flag is set to "0", indicating that the Mobile AP disables the dynamic power saving mode.

[0198] If the second device fails to associate with the first device, and all other devices associated with the first device support the dynamic power saving mode, a seventh wireless frame is determined, the seventh wireless frame indicating that the first device has enabled the dynamic power saving mode; the seventh wireless frame is then broadcast.

[0199] For example, after sending the third wireless frame, or after sending the fourth wireless frame, or after sending the fifth wireless frame, if the second device fails to associate with the first device and all other devices associated with the first device support the dynamic power saving mode, a seventh wireless frame can be determined, the seventh wireless frame indicating that the first device has enabled the dynamic power saving mode; and the seventh wireless frame can be broadcast.

[0200] In one embodiment, if the Legacy device fails to associate with the first device after the first device sends the third radio frame, the first device activates dynamic power saving mode and broadcasts information indicating that dynamic power saving mode has been activated. For example, the first device determines and sends the seventh radio frame.

[0203] In this embodiment of the disclosure, if the first device does not receive an Association Request frame from the Legacy device within a certain period after sending the third wireless frame, the first device activates a dynamic power-saving mode and broadcasts information indicating that the dynamic power-saving mode has been activated.

[0229] Figure 6 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 6, the embodiments of the present disclosure relate to a communication method, which includes:

[0230] Step 601, the first device 101 determines the ninth wireless frame; the ninth wireless frame includes first identification information, the first identification information indicating whether the first device 101 supports the dynamic power saving mode.

[0231] Optionally, the ninth radio frame may include, but is not limited to, a Probe Request frame, an Association Request frame, and a Reassociation Request frame.

[0232] Optionally, the ninth radio frame may include an Ultra-High Reliability Media Access Address Capabilities Information (UHR MAC Capabilities Information) field, which includes a DPS Support (Dynamic Power Save) flag bit, with first identification information carried in the DPS Support flag bit.

[0233] In some embodiments, the first identification information is set to a first parameter value, indicating that the first device supports dynamic power saving mode;

[0234] The first identification information is set to the second parameter value, indicating that the first device does not support dynamic power saving mode.

[0235] Optionally, the first parameter value can be "1" and the second parameter value can be "0". That is, when the DPS Support flag is set to "1", it indicates that the first device supports dynamic power saving mode; when the DPS Support flag is set to "0", it indicates that the first device does not support dynamic power saving mode.

[0236] In some embodiments, the ninth wireless frame further includes second identification information, which identifies whether the first device has enabled or disabled dynamic power saving mode.

[0237] Optionally, the ninth radio frame may also carry a first identification field, which includes a DPS Enable flag, and the second identification information may be carried in the DPS Enable flag.

[0238] In some embodiments, the second identification information is set to a third parameter value, indicating that the first device has enabled dynamic power saving mode;

[0239] The second identification information is set to the fourth parameter value, indicating that the first device has turned off the dynamic power saving mode.

[0240] Optionally, when the parameter value of the first identification information is set to the first parameter value, the second identification information is set to the third parameter value by default. For example, if the parameter value of the first identification information is set to "1", the parameter value of the second identification information is set to "1" by default; if the parameter value of the first identification information is set to "0", the parameter value of the second identification information is set to "0" by default.

[0241] Optionally, if the parameter value of the first identification information is set to the first parameter value, the second identification information is set to the fourth parameter value. For example, the parameter value of the first identification information is set to "1", and the parameter value of the second identification information is set to "0".

[0242] Optionally, the ninth wireless frame includes first identification information. If the first identification information indicates that the first device supports dynamic power saving mode, the first device can be enabled by default (that is, in this embodiment, the existence of second identification information or the value of the second identification information in the ninth wireless frame can be not limited).

[0243] For example, the ninth wireless frame includes first identification information but does not include second identification information. If the first identification information indicates that the first device supports dynamic power saving mode, the first device can be enabled by default. And / or, if the first identification information indicates that the first device does not support dynamic power saving mode, the first device can be disabled by default without further instructions.

[0244] Optionally, the ninth wireless frame includes a second identification information. If the second identification information indicates that the first device has enabled dynamic power saving mode, it can be assumed that the first device supports dynamic power saving mode (that is, in this embodiment, the existence of the first identification information or the value of the first identification information in the ninth wireless frame can be not limited).

[0245] For example, the ninth wireless frame includes second identification information but does not include first identification information. If the second identification information indicates that the first device has enabled dynamic power saving mode, the first device can be assumed to support dynamic power saving mode by default. And / or, if the second identification information indicates that the first device has disabled dynamic power saving mode, the first device can be assumed to not support dynamic power saving mode by default, and no further instruction is required.

[0246] In an optional embodiment, the values ​​of the first identification information and the second identification information may be unrelated and can be indicated based on the actual situation.

[0247] In some embodiments, the ninth wireless frame further includes third identification information, which identifies the communication parameters of the first device in dynamic power-saving mode.

[0248] Optionally, the ninth radio frame may also carry a second identification field, which includes a DPS Operation Parameters field, and the third identification information is carried in the DPS Operation Parameters field.

[0249] Optionally, the DPS Operation Parameters field is used to identify the operation parameters (i.e., communication parameters) of the first device in DPS mode. That is, the parameters carried in the DPS Operation Parameters field are the operation parameters of the first device in DPS mode.

[0250] Optionally, the third identification information may be carried in the ninth wireless frame, or carried after the first device sends the ninth wireless frame, or before receiving the first wireless frame, or in the identification field of the wireless frame sent by the first device.

[0251] Step 602: The first device 101 sends the ninth wireless frame to the second device 102; correspondingly, the second wireless frame 102 receives the ninth wireless frame sent by the first device 101.

[0252] In this embodiment of the disclosure, the first device maintains the dynamic power saving mode when it supports dynamic power saving mode and has not received the first wireless frame sent by the second device. For example, the Mobile AP carries the UHR MAC Capabilities Information field (with the parameter value of the DPS Support flag set to "1"), the UHR Operation Parameters field (with the parameter value of the DPS Enable flag set to "1"), and the DPS Operation Parameters field in the Beacon frame.

[0253] Step 603, the second device 102 sends a first wireless frame; wherein, the first wireless frame identifies whether the second device 102 supports the dynamic power saving mode, or whether the second device 102 supports sending a second wireless frame; the second wireless frame is used to instruct the device in the dynamic power saving mode to switch communication modes after receiving the second wireless frame.

[0254] In this embodiment of the disclosure, through the first radio frame, the non-AP STA can indicate to the associated device whether it supports dynamic power saving mode or whether it supports sending the second radio frame during the association process, which can effectively avoid the conflict between dynamic power saving mode and other power saving mechanisms (such as TWT mechanism and periodic power saving mode).

[0255] Step 604: The first device 101 maintains or disables the dynamic power saving mode according to the first wireless frame.

[0256] Optionally, under a first condition, the first device will disable the dynamic power-saving mode: wherein the first condition includes, but is not limited to, at least one of the following:

[0257] When a first device receives a first radio frame sent by at least one second device; wherein the second device is a Legacy non-AP STA (pre-UHR non-AP STA), and the first radio frame is a Probe Request frame;

[0258] When a first device receives a first radio frame sent by at least one second device; wherein the second device is a UHR non-AP STA that does not support sending initial control frames for dynamic power saving; the first radio frame is a Probe frame or an Association Request frame.

[0259] Optionally, under the first condition, the first device performing a response operation includes at least one of the following:

[0260] If the second device sending the first wireless frame is a Legacy non-AP STA, the first device disables dynamic power saving mode and replies with a Probe Response frame. After the Legacy non-AP STA establishes an association with the first device, the first device broadcasts the information about disabling dynamic power saving mode. For example, the first device carries a UHR Operation Parameters field in the Beacon frame, and the parameter value of the Enable flag bit in the Beacon frame is set to "0". Optionally, if the Legacy non-AP STA fails to associate with the first device after replying with the Probe Response frame, the first device will enable dynamic power saving mode and broadcast the information about enabling dynamic power saving mode. Optionally, if the first device does not receive an association request frame from the corresponding Legacy non-AP STA after replying with the Probe Response frame for a period of time, the first device will enable dynamic power saving mode and broadcast the information about enabling dynamic power saving mode.

[0261] The first device disables the dynamic power saving mode by indicating that the dynamic power saving mode is disabled in the Probe frame or Association Response frame (for example, by carrying the UHR Operation Parameters field in the Probe frame or Association Response frame, where the dynamic power saving Enable flag is set to 0); and broadcasts the disabled information.

[0262] Optionally, under the second condition, the first device will activate dynamic power-saving mode, and the second condition includes, but is not limited to:

[0263] The second device associated with the first device supports the first device operating in dynamic power saving mode;

[0264] Both the Legacy non-AP STA in the second device that transmits the first radio frame and the UHR non-AP STA that does not support transmitting the initial control frame for dynamic power saving are disconnected from the first device.

[0265] The communication method involved in the embodiments of this disclosure may include at least one of steps 601 to 604. For example, step 601 may be implemented as an independent embodiment, step 602 may be implemented as an independent embodiment, step 603 may be implemented as an independent embodiment, and step 604 may be implemented as an independent embodiment; steps 601+602 may be implemented as an independent embodiment, steps 602+603 may be implemented as an independent embodiment, and steps 603+604 may be implemented as an independent embodiment.
