[0111] Figure 1 It is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0112] like Figure 1 As shown, the communication system 100 includes a first device 101 and a second device 102 .

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] In related technologies, in order to further enhance the power-saving mechanism, a dynamic power saving mode (Dynamic Power Save, DPS) is proposed. For example, a Mobile AP (mobile access point device) or a non-AP STA can work in the dynamic power saving mode. When the communication device works in the dynamic power saving mode, it switches to the low capability (Low Capability, LC) mode; the communication capability of the device is limited in the LC mode, for example, it only supports the use of a single spatial stream and a low-rate modulation and coding scheme (Modulation and Coding Scheme, MCS) for transceiver operations, the communication bandwidth is 20MHz, and it only supports the reception of specific control frames or management frames. In addition, if the opposite device needs to exchange frames with it, the opposite device needs to send an initial control frame to it to switch it from the low capability mode to the higher capability mode, thereby realizing frame exchange with the opposite device. The initial control 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, the initial control frame is transmitted as a non-HT (duplicate) PPDU and is transmitted at a rate of 6Mb / s, 12Mb / s or 24Mb / s; the initial control frame can be a buffer status report poll (BSRP) trigger frame or a multiple user request to send (MU-RTS) trigger frame. Taking the site device as an example, when the site device supports dynamic power saving mode, the site device sends a dynamic power saving mode request to its associated access point device and carries relevant parameter information for entering dynamic power saving mode, such as the time to enter the low-capability mode state (including but not limited to the start time and duration); after the access point device receives the dynamic power saving mode request and is ready to serve the site device in dynamic power saving mode, it will send a response frame to the site device. When a station device operates in dynamic power saving mode, the access point device initiates transmission with the station device by sending an initial control frame. Upon receiving the initial control frame, the station device switches from a low-capability mode to a higher-capability state to facilitate frame exchange with the wireless station (access point) device that sent the initial control frame. The low-capability mode is a mode with limited operating parameters, such as 20MHz bandwidth, one spatial stream, 6Mb / s, 12Mb / s, or 24Mb / s, and a limited PPDU transmission format. The high-capability mode is a mode with at least one higher operating parameter than the low-capability mode.

[0123] While the dynamic power saving mechanism supports communication devices switching between different capability modes to reduce power consumption, the lack of clear signaling interactions and supporting state transition processes when devices need to disable dynamic power saving mode and restore normal communication capabilities can lead to untimely link switching and unstable communication performance, affecting overall system efficiency. Therefore, it is necessary to further standardize and improve the process of disabling / exiting dynamic power saving mode when the device is in dynamic power saving mode.

[0124] The embodiments of the present disclosure provide a communication method, a communication device, and a communication system for defining a shutdown / exit process in a dynamic power saving mode to ensure that the device can switch the communication capability mode in a timely and stable manner, thereby improving communication reliability and system response efficiency.

[0125] Figure 2 FIG. 1 is one of the interactive diagrams of the communication method according to the embodiment of the present disclosure. Figure 2 As shown, the above method includes:

[0126] In step 201, the second device 102 sends a first wireless frame; correspondingly, the first device 101 receives the first wireless frame; wherein the first wireless frame is used to respond to the second wireless frame sent by the first device 101, and the second wireless frame is used to request to turn off the dynamic power saving mode.

[0127] Specifically, after the first device establishes an association with the second device, the first device sends a second radio frame to the second device associated therewith; wherein the second radio frame identifies that the first device requests to turn off the dynamic power saving mode; accordingly, the second device receives the second radio frame sent by the first device, and replies to the first device with the first radio frame after receiving the second radio frame; wherein the first radio frame is used to respond to the second radio frame. 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; wherein the second radio frame includes but is not limited to a dynamic power saving mode request (DPS Mode Request) frame and a dynamic power saving mode operation notification (DPS Mode Notification) frame; wherein the second radio frame identifies, through identification information, that the second radio frame is used to request to turn off the dynamic power saving mode. Among them, the second wireless frame identifies that the first device requests to turn off the dynamic power saving mode; wherein, the second device is a device that supports the auxiliary dynamic power saving mode; the support for the auxiliary dynamic power saving mode means supporting the first device to enable the dynamic power saving mode, and then sending an initial control frame to the first device to enable the first device to switch from a communication mode with lower capability to a communication mode with higher capability.

[0128] In an embodiment of the present disclosure, after the first device establishes an association with the second device, the first device requests to turn off the dynamic power saving mode by sending a second wireless frame, and after receiving the first wireless frame sent by the second device to respond to the second wireless frame, the first device switches from the first capability communication mode when the dynamic power saving mode is enabled to the second communication mode when requesting to enable the dynamic power saving mode, thereby improving the signaling interaction and state switching process of the device when exiting the dynamic power saving mode, realizing timely recovery of communication capabilities, ensuring that the device can quickly adapt to conventional communication needs after exiting the dynamic power saving mode, improving data transmission efficiency and overall system performance, and avoiding communication interruption or service quality degradation caused by capability switching delays.

[0129] In some embodiments, the first capability communication mode and the second capability communication mode include at least one identical operating parameter, and a 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.

[0130] 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.

[0131] 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.

[0132] 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.

[0133] 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.

[0134] Step 202: The first device 101 switches from the first capability communication mode to the second capability communication mode.

[0135] In an embodiment of the present disclosure, after receiving the first wireless frame, the first device switches from the first capability communication mode to the second capability communication mode, so as to restore normal communication capability after turning off the dynamic power saving mode, so as to support communication with higher bandwidth, higher rate or more spatial streams, thereby improving data transmission efficiency and ensuring communication quality.

[0136] In some embodiments, the first capability communication mode includes at least one of the following:

[0137] a communication mode in which the first device is in the dynamic power saving mode and has not received an initial control ICF frame sent by the second device;

[0138] The communication mode of the first device after the dynamic power saving mode is enabled and the first device receives the ICF frame sent by the second device.

[0139] In an embodiment of the present disclosure, the first capability communication mode includes at least one of the following: first, a communication mode of the first device when the dynamic power saving mode is enabled and the initial control frame (ICF frame) sent by the second device is not received; second, a communication mode of the first device after the dynamic power saving mode is enabled and the ICF frame sent by the second device is received. These two situations correspond to the initial low capability state of the STA after entering the dynamic power saving mode (DPS) and the state of improving the communication capability after receiving the ICF frame. Specifically, when the ICF frame is not received, the first device may only support a channel bandwidth of 20MHz (BW=20MHz), a single spatial stream (NSS=1), and an MCS index of up to 5 (for example, MCS=5); after receiving the ICF frame, its communication capability can be improved to support a channel bandwidth of 40MHz or higher (for example, BW=40MHz or 80MHz), multiple spatial streams (such as NSS=2), and a higher MCS index (for example, MCS can reach 9 or 11). By distinguishing these two communication modes, the embodiment of the present disclosure can enable the first device to flexibly request to turn off the dynamic power saving mode under different capability states, and switch capabilities accordingly, thereby improving the communication capability management process of the device in the dynamic power saving mode, improving the timeliness of mode switching, and further ensuring communication efficiency and system stability.

[0140] For example, the site device sends a dynamic power saving mode request in the second capability communication mode, requesting to enable the dynamic power saving mode; wherein the second capability communication mode includes but is not limited to other communication modes except the dynamic power saving mode, such as multi-link communication mode, Wi-Fi mode, Bluetooth mode, etc.

[0141] The access point device associated with the site device replies with a response frame after receiving the request frame, and the site device enters the dynamic power saving mode (for example, the first capability communication mode) after receiving the response frame or not receiving the response frame but after a preset time period; when the site device enters the dynamic power saving mode and does not receive the initial control frame sent by the access point device, if the site device wants to turn off the dynamic power saving mode, at this time, the site device sends a second wireless frame and switches from the first capability communication mode to the second capability communication mode after receiving the response frame sent by the access point device.

[0142] For another example, the site device sends a dynamic power saving mode request in the second capability communication mode, requesting to enable the dynamic power saving mode; the access point device associated with the site device replies with a response frame after receiving the request frame, and the site device enters the dynamic power saving mode (for example, low capability communication mode) after receiving the response frame or not receiving the response frame but after a preset time period; during this period, the access point device sends an initial control (ICF) frame to instruct the site device to switch from the low capability communication mode to the first capability communication mode (the communication parameters of the capability communication mode are not specifically restricted and are specifically determined according to the communication parameters indicated by the access point device to the site device). If the site device wants to turn off the dynamic power saving mode in the first capability communication mode, it sends a second wireless frame and switches from the first capability communication mode to the second capability communication mode after receiving the response frame sent by the access point device.

[0143] In some embodiments, the switching from the first capability communication mode to the second capability communication mode includes:

[0144] The first radio frame indicates that the first device needs to respond immediately, and the first device sends a third radio frame and switches from the first capability communication mode to the second capability communication mode; wherein the third radio frame is used to respond to the first radio frame; or

[0145] The first radio frame indicates that the first device does not need to respond immediately, and the first device switches from the first capability communication mode to the second capability communication mode.

[0146] In the embodiment of the present disclosure, the process of switching from the first capability communication mode to the second capability communication mode may include the following cases 1 and 2:

[0147] Case 1: If the first wireless frame indicates that the first device needs to respond immediately (for example, the frame is an Action frame that requires an immediate response), the first device switches from the first capability communication mode to the second capability communication mode after sending a third wireless frame to respond to the frame.

[0148] Case 2: If the first radio frame indicates that the first device does not need to respond immediately (for example, the frame is an Action No Ack frame), the first device can complete the mode switching after receiving the frame.

[0149] In the disclosed embodiment, the first device switches from low-capability mode to high-capability mode at an appropriate time, depending on whether a wireless frame requires an immediate response. When a wireless frame requires a response, the first device completes the response before switching modes, avoiding the impact of premature switching on the stability of the frame response. When a wireless frame does not require a response, the first device can switch modes immediately after receiving the frame, reducing waiting time. This processing method improves the flexibility of the device's capability switching in dynamic power saving mode.

[0150] In some embodiments, the second radio frame further identifies at least one of the following:

[0151] The second radio frame is used to request to disable the dynamic power saving mode;

[0152] Request to turn off or exit the dynamic power saving mode flag;

[0153] A communication session with the second device.

[0154] In an embodiment of the present disclosure, the second radio frame is further used to identify at least one of the following: an identifier indicating that the frame is used to request the deactivation of the dynamic power saving mode, a identifier for requesting the deactivation or exit of the dynamic power saving mode, and the communication session to which the frame belongs. For example, the second radio frame may include a first identification field for indicating that the second radio frame is used to request the deactivation of the dynamic power saving mode, a second identification field for indicating whether to deactivate (exit) the dynamic power saving mode, and a third identification field for identifying this communication session. Optionally, the first identification field may be an ultra-high reliability action (UHR Action) field or a protected ultra-high reliability action (Protected UHR Action) field. When the first identification field is set to a first parameter value, it is used to indicate that the second radio frame is used to request the deactivation of the dynamic power saving mode; the second identification field may be a dynamic power saving mode (DPSMode) field. When it is set to a second parameter value (e.g., 0), it is used to instruct the first device to deactivate or exit the dynamic power saving mode; the third identification field may be a session identifier (Dialog Token) field, used to identify the communication session corresponding to the radio frame. It should be noted that the information carried by the second identification field and the third identification field can be located in different identification fields respectively, or can be combined and carried in the same identification field. This embodiment of the present disclosure does not impose any specific limitation on this.

[0155] In some embodiments, the first radio frame further identifies at least one of the following:

[0156] The first radio frame is used to respond to the second radio frame;

[0157] The current communication session with the first device.

[0158] In this embodiment of the present disclosure, the first radio frame is further used to identify at least one of the following information: that the frame is used in response to a second radio frame; that the second radio frame is used in dynamic power saving mode; and that the communication session to which the frame belongs. Specifically, the first radio frame may include a fourth identification field for indicating that the frame is in response to the second radio frame, and a fifth identification field for identifying the current communication session.

[0159] Optionally, the third identification field may be an ultra-high reliability operation (UHR Action) field or a protected ultra-high reliability operation (Protected UHR Action) field. When the fourth identification field is set to the third parameter value, it is used to indicate that the first radio frame is used to respond to the second radio frame; the fifth identification field may be a session identifier field (e.g., a Dialog Token field), the setting value of which is the same as the session identifier of the corresponding second radio frame in the first radio frame, to identify that the two belong to the same communication session. It should be noted that the information carried by the fourth identification field and the fifth identification field may be encapsulated in different fields respectively, or may be combined in the same identification field for carrying. This embodiment of the present disclosure does not impose specific restrictions on this.

[0160] In some embodiments,

[0161] The first radio frame includes at least one of the following:

[0162] Action frame that requires immediate response, Action frame that does not require immediate response, Action No Ackframe.

[0163] In the disclosed embodiment, the first wireless frame may be an action frame (Action frame) requiring an immediate response, or an action frame (Action No Ack frame) not requiring an immediate response, for the second device to respond to the request. By distinguishing the response requirements of the action frame, the timing of capability switching of the first device can be flexibly controlled to adapt to different communication timing requirements.

[0164] In some embodiments, the second radio frame further identifies at least one of the following:

[0165] The second radio frame is used to request to disable the dynamic power saving mode;

[0166] Request to turn off or exit the dynamic power saving mode flag;

[0167] A communication session with the second device.

[0168] In an embodiment of the present disclosure, the second radio frame is further used to identify at least one of the following: an identifier indicating that the frame is used to request deactivation of the dynamic power saving mode, an identifier indicating that the frame is used to request deactivation of the dynamic power saving mode, or an identifier indicating that the frame is used to exit the dynamic power saving mode, and a communication session to which the frame belongs. For example, the second radio frame may include a first identification field indicating that the second radio frame is used to request deactivation of the dynamic power saving mode, a second identification field indicating whether to request deactivation (exit) of the dynamic power saving mode, and a third identification field identifying the current communication session. Optionally, the second radio frame includes an ultra-high reliability operation (UHR Action) field or a protected ultra-high reliability operation (Protected UHR Action) field, and when the UHR Action or Protected UHR Action field indicates that the second radio frame is a dynamic power saving mode notification (DPS Mode Notification) frame, the second radio frame includes a first identification field, such as a DPS Mode Request field, which, when the first identification field is set to a first parameter value, is used to indicate that the second radio frame is used to request to turn off the dynamic power saving mode; the second identification field may be a dynamic power saving mode (DPS Mode) field, which, when set to a second parameter value (for example, 0), is used to instruct the first device to turn off or exit the dynamic power saving mode; the third identification field may be a session identifier (Dialog Token) field, which is used to identify the communication session corresponding to the radio frame. It should be noted that the information carried by the second identification field and the third identification field may be located in different identification fields respectively, or may be combined in the same identification field for carrying, and the embodiment of the present disclosure does not impose specific restrictions on this.

[0169] In some embodiments, the first radio frame further identifies at least one of the following:

[0170] The first radio frame is used to respond to the second radio frame;

[0171] A communication session with the first device.

[0172] In this embodiment of the present disclosure, the first radio frame is further used to identify at least one of the following information: that the frame is used to respond to the second radio frame; that the second radio frame is used to request a dynamic power saving mode; and the communication session to which the frame belongs. Specifically, the first radio frame may include a fourth identification field for indicating that it is a dynamic power saving mode response, and a fifth identification field for identifying the current communication session.

[0173] Optionally, the first radio frame includes an ultra-high reliability operation (UHR Action) field or a protected ultra-high reliability operation (Protected UHR Action) field, and when the UHR Action or Protected UHR Action field indicates that the second radio frame is a dynamic power saving mode notification (DPS Mode Notification) frame, the first radio frame includes a fourth identification field, such as a DPS Mode Response field. When the fourth identification field is set to a third parameter value, it is used to indicate that the first radio frame is used to respond to the second radio frame; the fifth identification field can be a session identifier field (such as a DialogToken field), and its setting value is the same as the session identifier of the corresponding second radio frame in the first radio frame, used to identify that the two belong to the same communication session. It should be noted that the information carried by the fourth identification field and the fifth identification field can be encapsulated in different fields respectively, or can be combined in the same identification field for carrying, and the embodiment of the present disclosure does not impose specific restrictions on this.

[0174] In some embodiments, when the first wireless frame and the second wireless frame are both dynamic power saving mode notification frames, the fourth identification field contained in the first wireless frame and the first identification field identified by the second wireless frame may be the same identification field in the dynamic power saving mode notification frame, or may be two different identification fields.

[0175] Optionally, the fourth identification field included in the first radio frame and the first identification field identified by the second radio frame are the same identification field in the dynamic power saving mode notification frame. For example, the dynamic power saving mode notification frame includes a DPS Mode Request identification field, the DPS Mode Request identification field is set to 1 in the second radio frame, and the DPS ModeRequest identification field is set to 0 in the first radio frame; or, the dynamic power saving mode notification frame includes a DPS Mode Response identification field, the DPS Mode Response identification field is set to 0 in the second radio frame, and the DPS ModeResponse identification field is set to 1 in the first radio frame. That is, the dynamic power saving mode notification frame includes one of the DPS Mode Request identification field or the DPS Mode Response identification field, and indicates through different parameter values ​​that the dynamic power saving mode notification frame is used for dynamic power saving mode request or dynamic power saving mode response.

[0176] Optionally, the fourth identification field included in the first radio frame and the first identification field identified by the second radio frame are different identification fields in the dynamic power saving mode notification frame. For example, the dynamic power saving mode notification frame includes a DPS Mode Request identification field and a DPS Mode Response identification field; in the second radio frame, the DPS Mode Request identification field is set to 1, and in the first radio frame, the DPS Mode Response identification field is set to 1. That is, the dynamic power saving mode notification frame includes a DPS Mode Request identification field and a DPS Mode Response identification field to indicate that the dynamic power saving mode notification frame is used for dynamic power saving mode request and dynamic power saving mode response, respectively.

[0177] In some embodiments, the access point device determines that the first device switches from the first capability communication mode to the second capability communication mode after receiving the first radio frame, including:

[0178] The first radio frame indicates that the first device needs to respond immediately, and the second device receives a third radio frame and determines that the first device switches from the first capability communication mode to the second capability communication mode; wherein the third radio frame is used to respond to the first radio frame;

[0179] The first radio frame indicates that the first device does not need to respond immediately, and the second device determines that the first device switches from the first capability communication mode to the second capability communication mode.

[0180] In the disclosed embodiment, an access point device determines when the first device has completed switching from a first capability communication mode to a second capability communication mode by determining a response requirement in a first radio frame. When the first radio frame indicates that an immediate response is required, the access point device considers the capability switching to be complete upon receiving a third radio frame (e.g., an acknowledgment frame) sent by the first device. If the first radio frame indicates that an immediate response is not required, the access point device determines that the capability switching has been completed upon sending the third radio frame. This enables the access point device to accurately determine the state change of the peer device based on the interaction behavior, facilitating the rational arrangement of subsequent data scheduling or resource allocation, and effectively improving system synchronization and communication efficiency.

[0189] Figure 3 This is the second interactive diagram of the communication method according to the embodiment of the present disclosure. Figure 3 As shown, the embodiment of the present disclosure relates to a communication method, which includes:

[0190] In step 301, the first device 101 sends a second radio frame; correspondingly, the second device 102 receives the second radio frame; wherein, the second radio frame is used to request to turn off the dynamic power saving mode.

[0191] The first device sends a second wireless frame to the second device, requesting to disable the dynamic power saving mode, and the second device receives the request. This step is used to initiate the exit process of the dynamic power saving mode, clarifying that the first device wishes to switch from the communication capability mode in the dynamic power saving mode to the communication capability mode when requesting to enable the dynamic power saving mode.

[0192] Step 302 , the second device 102 sends a first radio frame; correspondingly, the first device 101 receives the first radio frame; wherein, the first radio frame is used to respond to the second radio frame sent by the first device 101 .

[0193] After receiving the request, the second device sends a first wireless frame to the first device in response, and the first device receives the response frame. This step establishes a control interaction for disabling dynamic power saving mode, ensuring that the first device performs capability switching after receiving an explicit response, and ensuring the stability of frame exchange.

[0194] Step 303: When the first radio frame indicates that the first device 101 needs to respond immediately, the first device 101 sends a third radio frame; correspondingly, the second device 102 receives the third radio frame.

[0195] In this disclosed embodiment, if the first radio frame indicates that the first device requires an immediate response, the first device sends a third radio frame to the second device as an acknowledgment or response to the first radio frame. This step ensures that, in scenarios where the protocol requires an immediate response, the first device completes the necessary response operations before switching communication capabilities, thus avoiding response failures caused by premature switching.

[0196] Step 304: After sending the third radio frame, the first device 101 switches from the first capability communication mode to the second capability communication mode.

[0197] In the disclosed embodiment, after sending the third radio frame, the first device switches from the first capability communication mode to the second capability communication mode. Specifically, the device switches from the communication capability mode in dynamic power saving mode to the communication capability mode in which the dynamic power saving mode is requested to be enabled. This step ensures that capability enhancement occurs only after the necessary frame exchange is completed, improves the process for disabling dynamic power saving mode, enhances communication efficiency, and reduces latency.

[0198] The communication method involved in the embodiments of the present disclosure may include steps 301 to 304. For example, step 301 may be implemented as an independent embodiment, step 302 may be implemented as an independent embodiment, step 303 may be implemented as an independent embodiment, step 304 may be implemented as an independent embodiment, steps 301+302 may be implemented as an independent embodiment, steps 302+303 may be implemented as an independent embodiment, steps 303+304 may be implemented as an independent embodiment, steps 301+302+303 may be implemented as an independent embodiment, and steps 301+302+303+304 may be implemented as an independent embodiment.

[0199] 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.

[0200] Figure 4 This is the third interactive diagram of the communication method according to the embodiment of the present disclosure. Figure 4 As shown, the embodiment of the present disclosure relates to a communication method, which includes:

[0201] In step 401, the first device 101 sends a second radio frame; correspondingly, the second device 102 receives the second radio frame; wherein, the second radio frame is used to request to turn off the dynamic power saving mode.

[0202] The first device sends a second wireless frame to the second device, requesting to disable the dynamic power saving mode, and the second device receives the request frame. This step is used to initiate the exit process of the dynamic power saving mode, clarifying that the first device wishes to switch from the communication capability mode in the dynamic power saving mode to the communication capability mode when requesting to enable the dynamic power saving mode.

[0203] In step 402 , the second device 102 sends a first radio frame; correspondingly, the first device 101 receives the first radio frame; wherein, the first radio frame is used to respond to the second radio frame sent by the first device 101 .

[0204] After receiving the request, the second device sends a first wireless frame to the first device in response, and the first device receives the response frame. This step establishes a control interaction for disabling dynamic power saving mode, ensuring that the first device performs capability switching after receiving an explicit response, and ensuring the stability of frame exchange.

[0205] Step 403: If the first radio frame indicates that the first device 101 does not need to respond immediately, the first device 101 switches from the first capability communication mode to the second capability communication mode after receiving the first radio frame.

[0206] Among them, if the first wireless frame indicates that the first device does not need to respond immediately, the first device will directly switch from the first capability communication mode to the second capability communication mode after receiving the frame, and can complete the switching of the communication mode without waiting for the subsequent response process, which helps to shorten the delay for the device to recover from a low power consumption state to a high performance state.

[0207] The communication method involved in the embodiments of the present disclosure may include steps 401 to 403. For example, step 401 may be implemented as an independent embodiment, step 402 may be implemented as an independent embodiment, step 403 may be implemented as an independent embodiment, steps 401+402 may be implemented as an independent embodiment, steps 402+403 may be implemented as an independent embodiment, and steps 401+402+403 may be implemented as an independent embodiment.

[0208] 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.

[0209] The following is described through the first embodiment:

[0210] First embodiment:

[0211] In an embodiment of the present disclosure, a site device that supports the dynamic power saving mode can send a dynamic power saving mode request to an access point device that is associated with it and supports the auxiliary dynamic power saving mode, in order to request to enable or disable the dynamic power saving mode. Specifically, the site device sends a request frame, and the request frame contains a dynamic power saving mode (DPS Mode) field, and the DPS Mode field is set to 1, indicating a request to enter (enable) the dynamic power saving mode; after the access point device receives the request and is ready to serve the site device in the dynamic power saving mode, it will send a response frame to the site device. Correspondingly, the site device sends a request frame containing a DPS Mode field set to 0, indicating a request to exit (turn off) the dynamic power saving mode to the access point device. However, in the related art, regarding the site device making a DPS mode request and the access point device receiving the request, when requesting to turn off the dynamic power saving mode, the respective operating parameters and behavioral actions have not yet been clarified. Therefore, signaling and processes need to be standardized.

[0212] To address the above issues, embodiments of the present disclosure propose a communication method. Specifically, a site device can disable (exit) dynamic power saving mode by sending a dynamic power saving mode request to its associated access point device. The access point device responds to the dynamic power saving mode disable request. The site device then determines its operating mode and operating parameters based on the response. Based on this method, the dynamic power saving mode negotiation process is improved, site actions in dynamic power saving mode are standardized, and dynamic power saving mode is further improved.

[0213] In some embodiments, the station device sends a second wireless frame to its associated access point device, wherein the second wireless frame requests to turn off (exit) the dynamic power saving mode (DPS Mode). The second wireless frame includes but is not limited to:

[0214] A first identification field is used to indicate that the second radio frame is used to request to disable the DPS mode. Optionally, the first identification field may be a UHR Action field or a Protected UHR Action field. When the first identification field is set to a first parameter value, it indicates that the second radio frame is a DPS Mode request frame;

[0215] A second identification field is used to indicate that DPS Mode is turned off (or exited). Optionally, the second identification field may be a DPSMode field. When the second identification field is set to a third parameter value (e.g., 0), it indicates that DPS Mode is turned off (or exited).

[0216] The third identification field is used to indicate this conversation. Optionally, the third identification field may be a Dialog Token field.

[0217] In some embodiments, after receiving the second radio frame, the access point device sends a first radio frame in response, where the first radio frame includes but is not limited to:

[0218] A fourth identification field is used to indicate that the first radio frame is used to respond to the second radio frame. Optionally, the third identification field may be a UHR Action or Protected UHR Action field, and when the third identification field is set to a fourth parameter value, it indicates that the first radio frame is used to respond to the second radio frame.

[0219] The fifth identification field is used to indicate this reply. The fourth identification field is set the same as the third identification field in the second radio frame.

[0220] In some embodiments, after sending the second radio frame, the site device performs the following operations:

[0221] The second identification field in the second radio frame is set to a third parameter value, and when the first radio frame is received, if the first radio frame requests an immediate response (the first radio frame is an Action frame), after the site device sends the third radio frame, it switches from the first capability communication mode in the dynamic power saving mode to the second capability communication mode when the site device requests to enable the dynamic power saving mode. Wherein, the third radio frame confirms the first radio frame, such as an Acknowledgement (ACK) frame; if the first radio frame does not request an immediate response (the first radio frame is an Action No Ack frame), then after the site device receives the first radio frame, the site device switches from the first capability communication mode in the dynamic power saving mode to the second capability communication mode when the site device requests to enable the dynamic power saving mode.

[0222] In some embodiments, after receiving the second wireless frame, the access point device further performs the following operations:

[0223] When the second identification field in the second wireless frame is set to the third parameter value, if the first wireless frame requests an immediate response (the first wireless frame is an Action frame), after receiving the third wireless frame sent by the site device, it is considered that the site device has entered the DPS mode, and it is considered that the site device has switched from the first capability communication mode under the dynamic power saving mode to the second capability communication mode when the site device requests to enable the dynamic power saving mode; if the first wireless frame does not request an immediate response (the first wireless frame is an Action No Ack frame), after sending the first wireless frame, it is considered that the site device has switched from the first capability communication mode under the dynamic power saving mode to the second capability communication mode when the site device requests to enable the dynamic power saving mode.
