[0041] The embodiments of the present disclosure provide a communication method, a communication device, and a communication system.

[0042] In a first aspect, an embodiment of the present disclosure provides a communication method, applied to a first device, the method comprising:

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

[0044] Maintain or disable the dynamic power saving mode according to the first radio frame.

[0045] In the above embodiment, by determining whether to maintain or disable power saving mode in dynamic power saving mode based on the received first radio frame information, efficient resource management and energy conservation are achieved, avoiding unnecessary energy waste. This method can improve the device's response speed and communication stability in changing communication environments, while effectively reducing the time it takes for the device to switch modes, 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 according to the first radio frame includes one or more of the following:

[0047] The second device that sends the first wireless frame is a first-category device, and the dynamic power saving mode is turned off; wherein the first-category 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-category device, and the dynamic power saving mode is turned off; wherein the second-category 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 device and maintains the dynamic power saving mode; wherein, the third type device is a device that supports sending the second wireless frame.

[0050] In the above embodiment, the device's power saving mode is flexibly adjusted based on the received first radio frame indication information. Specifically, the device can determine whether to maintain or disable dynamic power saving mode based on the type of second device. This enables more intelligent and efficient resource management by identifying device types and making corresponding adjustments, avoiding unnecessary power consumption while improving the device's responsiveness and stability in various communication scenarios.

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

[0052] After the first-category device and the second-category device are both disassociated from the first device, the dynamic power saving mode is enabled.

[0053] In the above embodiment, after the first and second category devices are disassociated from the first device, the dynamic power saving mode is automatically enabled. By intelligently determining the device association status, the dynamic power saving mode is ensured to be enabled promptly when high power consumption is no longer required, 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] Sending a third radio frame to the second device and turning off the dynamic power saving mode; wherein the second device is a first-category device, and the first radio frame indicates that the second device does not support the dynamic power saving mode; and the third radio frame is a response frame to the first radio frame;

[0056] sending a fourth radio frame to the second device, where the fourth radio frame indicates that the first device has turned off the dynamic power saving mode; wherein the second device is a second-category device, and the first radio frame indicates that the second device does not support sending the second radio frame; and the fourth radio frame is a response frame to the first radio frame;

[0057] Determine a fifth radio frame, where the fifth radio frame indicates that the first device turns off the dynamic power saving mode; and broadcast the fifth radio frame.

[0058] In the above embodiment, by intelligently identifying and responding to different types of devices, dynamic power saving mode disabling becomes more flexible and efficient. This handling of different device types helps improve system energy efficiency and communication stability, while ensuring timely adjustments under different operating conditions, reducing unnecessary power consumption and 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 and maintain the dynamic power saving mode; wherein, the second device is a third-category 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 embodiment, when the second device is a third-category device and the second device supports sending the second wireless frame, the first device maintains the dynamic power saving mode and sends the sixth wireless frame to the second device, thereby achieving efficient resource management and energy saving and avoiding unnecessary energy waste.

[0062] In combination with some embodiments of the first aspect, in some embodiments, after sending 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 other devices associated with the first device all support the dynamic power saving mode, determining a seventh radio frame, where the seventh radio frame indicates that the first device has enabled the dynamic power saving mode; and broadcasting the seventh radio frame.

[0064] When the first device does not receive the association request frame sent by the second device and other devices associated with the first device all support the dynamic power saving mode, determine an eighth wireless frame, and the eighth wireless frame indicates that the first device turns on the dynamic power saving mode; broadcast the eighth wireless frame.

[0065] In the above embodiment, by automatically enabling dynamic power saving mode under specific conditions (such as association failure or failure to receive an association request frame) and broadcasting relevant status information, the device's energy efficiency can be improved and unnecessary energy consumption can be reduced. In addition, the broadcast mechanism ensures that other devices are promptly informed of the enabled state of 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 radio frame sent by the second device, the method further includes:

[0067] Determine a ninth radio frame; the ninth radio frame includes first identification information, where the first identification information identifies whether the first device supports the dynamic power saving mode;

[0068] The ninth radio frame is sent.

[0069] In the above embodiment, before receiving the first wireless frame sent by the second device, the first device sends the ninth wireless frame to inform the network or other devices whether it supports the dynamic power saving mode, so that the second device can make corresponding decisions 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 a second parameter value, indicating that the first device does not support the dynamic power saving mode.

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

[0073] In combination with some embodiments of the first aspect, in some embodiments, the ninth wireless frame further includes second identification information, and the second identification information identifies: whether the first device turns on or off the dynamic power saving mode.

[0074] In the above embodiment, the first device explicitly indicates its current dynamic power saving mode status (on or off) by adding the second identification information in the ninth radio frame. This approach 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 a fourth parameter value, indicating that the first device turns off the dynamic power saving mode.

[0077] In the above embodiment, the first device can transmit specific information about the dynamic power saving mode in the ninth radio frame by setting different parameter values. The combination of the first identification information and the second identification information can clearly indicate whether the first device has the power saving mode enabled or disabled. 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 combination with some embodiments of the first aspect, in some embodiments, the ninth wireless frame further includes third identification information, and the third identification information identifies: communication parameters of the first device in the dynamic power saving mode.

[0079] In the above embodiment, by adding the third identification information in the ninth radio frame, the first device can transmit its communication parameters in the dynamic power saving mode, so that the second device communicating with it can make corresponding adjustments according to these parameters.

[0080] 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;

[0081] 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.

[0082] In the above embodiment, by switching to the first capability communication mode, the first device can communicate with lower power consumption, thereby saving energy and maximizing the battery life when high communication performance is not required. At the same time, the differentiated settings between the first capability communication mode and the second capability communication mode (such as the difference in parameter values) further optimize the utilization efficiency of communication resources. The switching mechanism can also ensure that the device can still maintain basic communication capabilities in low power consumption 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, it has a significant optimization effect.

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.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] 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, 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, and other factors, a STA cannot detect other STAs that are farther away from it, and the two STAs are each other's hidden nodes.

[0144] 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:

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

[0146] 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.

[0147] To further enhance power conservation, 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 a 20MHz operating bandwidth, a single spatial stream, and a low-rate MCS (Modulation and Coding Scheme) for transmission and reception, and only supports the reception of specific control or management frames.

[0148] However, during the association process, enabling or disabling dynamic power saving mode for a non-AP STA may cause some problems. On the one hand, if a non-AP STA enables dynamic power saving mode during the association process, it may conflict with the target wake time (TWT) mechanism and the periodic power saving mode. For example, the TWT mechanism requires the device to be active at a predetermined wake-up time, but the dynamic power saving mode may not be able to respond to the TWT requirement in a timely manner due to switching delays. On the other hand, if a non-AP STA disables dynamic power saving mode, it will cause the device to always operate in a single power mode and lose the ability to dynamically adjust the power mode, thereby reducing the power saving effect.

[0149] In the embodiment of the present disclosure, the second device includes but is not limited to an ultra-high reliability multi-link station device (UHR non-AP STA), a traditional multi-link station device (Legacy non-AP STA), and a multi-link station device applicable to a standard before the ultra-high reliability standard (pre-UHR non-AP STA). The first radio frame includes but is not limited to a probe request frame (ProbeRequest), an association request frame (AssociationRequest), and a reassociation request frame (ReassociationResponse). The second device sends a first radio frame, and the first radio frame 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 the dynamic power saving mode to switch the communication mode after receiving the second radio frame. For example, after the first device in dynamic power saving mode is turned on, it switches from a low-capability communication mode to a high-capability communication mode to complete the frame exchange after receiving the second radio frame sent by the second device. The second wireless frame includes but is not limited to an initial control frame (ICF); wherein the initial control frame includes but is not limited to a multiple user request to send Trigger frame (MU-RTS Trigger frame) and a buffer status report polling trigger frame (BSRP Trigger frame).

[0150] In the embodiment of the present disclosure, through the first radio frame, the non-AP STA can identify to the associated device whether it supports the dynamic power saving mode or whether it supports sending the second radio frame during the association process, which can effectively avoid conflicts between the dynamic power saving mode and other power saving mechanisms (such as the TWT mechanism and the periodic power saving mode). Specifically, when the non-AP STA explicitly identifies that it supports the dynamic power saving mode, the associated device can optimize the configuration for this mode to avoid conflicts with the scheduling logic of other mechanisms; and when the non-AP STA identifies that it does not support the dynamic power saving mode, the associated device can directly select other power saving mechanisms to avoid interference from the dynamic power saving mode. This capability identification mechanism is completed in the early 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 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.

[0153] 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.

[0154] Optionally, the first capability communication mode may also be referred to as a first power mode, a low energy communication mode, a low capability communication mode, a low power communication mode, a lower capability communication mode, a listening mode, or a low power communication phase, etc., and the embodiments of the present disclosure do not limit these names. 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.

[0155] 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.

[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 (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.

[0157] 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.

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

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

[0160] In the Mobile AP scenario, there are also some problems with enabling or disabling the dynamic power saving mode of the Mobile AP. On the one hand, since Legacy non-AP STA or pre-UHR non-AP STA (hereinafter referred to as Legacy devices) usually follow early standards, they do not support the parsing or negotiation logic of the dynamic power saving mode. If the Mobile AP enters the dynamic power saving mode, the Legacy device may not be able to recognize and adapt to the dynamic power saving mode, resulting in communication failure between devices. On the other hand, if the Mobile AP disables the dynamic power saving mode during the association process, it needs to always operate in high power mode to ensure communication quality. Although this situation avoids compatibility issues with Legacy devices, it greatly increases the energy consumption of the Mobile AP, which violates the design goal of low-power optimization.

[0161] Optionally, when the first device supports the dynamic power saving mode, the dynamic power saving mode is enabled by default, which means that the Mobile AP preferentially chooses to operate in the dynamic power saving mode when no special instructions are received or specific conditions are encountered. The dynamic power saving mode is enabled so that the Mobile AP can achieve low power consumption operation by default.

[0162] In the embodiment of the present disclosure, if the first device supports the dynamic power saving mode, the first device is in the dynamic power saving state before receiving the first radio frame. Then, after receiving the first radio frame sent by the second device, the first device performs any one of the following response operations from Case 1 to Case 3:

[0163] Case 1: The first device turns off the dynamic power saving mode according to the first radio 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-category device, and the dynamic power saving mode is turned off; wherein the first-category 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-category device, and the dynamic power saving mode is turned off; wherein the second-category device is a device that does not support sending the second wireless frame;

[0167] In the embodiment of the present disclosure, when the second device that sends the first radio frame is a legacy device or a UHR non-AP STA that does not support the 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 wireless frame; wherein, the type of the second device may be carried in a certain identification bit of the first wireless frame, or may not be carried in a certain identification bit of the first wireless frame, and no specific limitation 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 dynamic power saving mode, the Mobile AP disables dynamic power saving mode. In this case, to ensure that the Mobile AP and the legacy device can establish an association and complete communication, the Mobile AP disables dynamic power saving mode and reverts to a traditional communication mode compatible with the legacy device. This shutdown operation not only avoids association failures due to dynamic power saving mode incompatibility but also ensures that the Mobile AP can flexibly adapt to the capabilities of different devices, thereby improving system compatibility and stability.

[0170] In an embodiment of the present disclosure, when the second device that sends the first radio frame is a UHR non-AP STA, the dynamic power saving mode is turned off. For example, the Mobile AP receives a ProbeRequest frame or a (Re)Association Request frame sent by at least one UHR non-AP STA, but the UHR non-AP STA is a device that does not support sending the second radio frame, then the Mobile AP turns off the dynamic power saving mode to avoid communication failure or collaboration problems caused by enabling an incompatible dynamic power saving mechanism in subsequent communications. After turning off the dynamic power saving mode, the Mobile AP can transmit data with the UHR non-AP STA in a traditional communication manner, thereby ensuring the normal communication and system stability. Among them, the UHR non-AP STA indicates whether the UHR non-AP STA supports sending the second radio frame through the dynamic power saving mode auxiliary support (DPS Assist Support) flag of the first radio frame. For example, in the above case, the parameter value of the DPS Assist Support flag is set to "0".

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

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

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

[0174] Case three: the first device turns on the dynamic power saving mode according to the first radio frame.

[0175] In some embodiments, the dynamic power saving mode is enabled after both the first-category device and the second-category device are disassociated from the first device.

[0176] Optionally, after the first type of devices and the second type of devices in the second device that sent the first radio frame are both disassociated from the first device, the dynamic power saving mode is enabled.

[0177] In the disclosed embodiment, the first-category device is a legacy device, and the second-category device is a UHR non-AP STA that does not support sending the second radio frame. Therefore, after both the first-category device and the second-category device are disassociated from the first device, the remaining devices associated with the first device are all UHR non-AP STAs that support sending the second radio frame. Therefore, the first device can re-enable dynamic power saving mode to further reduce energy consumption and improve device power saving.

[0186] 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:

[0187] Step 301: The second device 102 sends a first radio frame; wherein the first radio frame indicates whether the second device 102 supports the dynamic power saving mode or whether the second device 102 supports sending a second radio frame; and the second radio frame is used to instruct the device in the dynamic power saving mode to switch the communication mode after receiving the second radio frame.

[0188] In an embodiment of the present disclosure, the second device sends a first wireless frame, and 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; wherein, the second device includes but is not limited to first category devices, second category devices and third category devices.

[0189] Step 302: When the first radio frame indicates that the second device 102 sending the first radio frame is a first-category device, the first device 101 turns off the dynamic power saving mode.

[0190] In an embodiment of the present disclosure, when 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 the dynamic power saving mode, the dynamic power saving mode is turned off.

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

[0192] In the disclosed embodiment, if the second device is a legacy device or a UHR non-APSTA that does not support dynamic power saving mode, the Mobile AP transmits a third radio frame after disabling dynamic power saving mode. The third radio frame is a Probe Response frame, which is used to respond to the first radio frame.

[0193] In some embodiments, after turning off the dynamic power saving mode, the method further includes:

[0194] Determining a fifth radio frame, where the fifth radio frame indicates that the first device turns off the dynamic power saving mode;

[0195] The fifth radio frame is broadcast.

[0196] In the disclosed embodiment, after a 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 information indicating that dynamic power saving mode is disabled. For example, the Mobile AP determines and transmits a Beacon frame; the Beacon frame carries an Ultra High Reliability Operation Parameters field (UHR Operation Parameters); 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 has disabled dynamic power saving mode.

[0197] In some embodiments, the method further comprises:

[0198] When the second device fails to associate with the first device and other devices associated with the first device all support the dynamic power saving mode, determine a seventh wireless frame, where the seventh wireless frame indicates that the first device has turned on the dynamic power saving mode; and broadcast the seventh wireless frame.

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

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

[0201] In some embodiments, the method further comprises:

[0202] When the first device does not receive the association request frame sent by the second device and other devices associated with the first device all support the dynamic power saving mode, determine an eighth wireless frame, and the eighth wireless frame indicates that the first device turns on the dynamic power saving mode; broadcast the eighth wireless frame.

[0203] In an embodiment of the present disclosure, if the first device does not receive an Association Request frame from a legacy device within a period of time after sending the third radio frame, the first device enables dynamic power saving mode and broadcasts information indicating that the dynamic power saving mode has been enabled. For example, the first device determines and sends an eighth radio frame.

[0229] Figure 6 FIG. 1 is an interactive diagram of a communication method according to an embodiment of the present disclosure. Figure 6 As shown, the embodiment of the present disclosure relates to a communication method, which includes:

[0230] Step 601: The first device 101 determines a ninth radio frame; the ninth radio frame includes first identification information, and the first identification information identifies 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.

For example, when 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; or when 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, when 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. When the first identification information indicates that the first device supports the dynamic power saving mode, the first device can be defaulted to turning on the dynamic power saving mode (that is, the embodiment of the present application may not limit whether the ninth wireless frame contains second identification information or the value of the second identification information).

[0243] For example, the ninth wireless frame includes the first identification information but does not include the second identification information. When the first identification information indicates that the first device supports the dynamic power saving mode, the first device can be defaulted to turning on the dynamic power saving mode, and / or, when the first identification information indicates that the first device does not support the dynamic power saving mode, the first device can naturally be defaulted to turning off the dynamic power saving mode without further instructions.

[0244] Optionally, the ninth wireless frame includes the second identification information. When the second identification information indicates that the first device turns on the dynamic power saving mode, it can naturally be assumed that the first device supports the dynamic power saving mode (that is, the embodiment of the present application may not limit whether the ninth wireless frame contains the first identification information or the value of the first identification information).

[0245] For example, the ninth wireless frame includes the second identification information but does not include the first identification information. When the second identification information indicates that the first device turns on the dynamic power saving mode, it can be assumed that the first device supports the dynamic power saving mode, and / or, when the second identification information indicates that the first device turns off the dynamic power saving mode, it can be assumed that the first device does not support the dynamic power saving mode, and no further instructions are required.

[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.

[0252] In an embodiment of the present disclosure, the first device maintains the dynamic power saving mode when it supports the dynamic power saving mode and does not receive a first radio frame sent by the second device. For example, the Mobile AP carries the UHR MACCapabilities Information field (the parameter value of the DPS Support flag is set to "1"), the UHR Operation Parameters field (the parameter value of the DPS Enable flag is 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 indicate that the device in the dynamic power saving mode switches the communication mode after receiving the second wireless frame.

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

Optionally, after the first device replies to the Probe Response frame, if the legacy non-AP STA fails to associate with it, the first device will turn on the dynamic power saving mode and broadcast the information of turning on the dynamic power saving mode. Optionally, if the first device does not receive an association request frame sent by the corresponding legacy non-AP STA after a period of time after replying to the Probe Response frame, the first device will turn on the dynamic power saving mode and broadcast the information of turning on the dynamic power saving mode.

[0261] The first device turns off the dynamic power saving mode, indicates that the dynamic power saving mode is disabled in a Probe frame or an Association Response frame (for example, the Probe frame or the Association Response frame carries a UHR OperationParameters field with the dynamic power saving Enable flag set to 0); and broadcasts the disabling information.

[0262] Optionally, under a second condition, the first device will turn on the dynamic power saving mode. The second condition includes but is not limited to:
