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

[0112] As shown in Figure 1, 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 (STA) or an access point (AP). The second device may be an access point or a station. 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 may be at least one of, but is not limited to, a mobile phone, a wearable device, an IoT device that supports Wi-Fi communication, a car with Wi-Fi communication capabilities, a smart car, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and a wireless terminal device in a smart home.

[0115] Specifically, the first device 101 and the second device 102 can be terminal devices or network devices equipped with Wi-Fi chips. Optionally, the first device 101 and the second device 102 can support various WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, and 802.11bn, as well as the next-generation 802.11 protocol, but are not limited to these.

[0116] In some embodiments, the first device 101 and the second device 102 can be access points for mobile terminals to access a wired network. An AP acts as a bridge connecting wired and wireless networks, its main function being to connect various wireless network clients together and then connect the wireless network to an Ethernet network. Specifically, an AP can be a terminal device or network device equipped with a Wi-Fi chip. Optionally, the AP can support various WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, and 802.11bn, as well as the next-generation 802.11 protocol, but is not limited to these.

[0117] Optionally, in this embodiment of the disclosure, AP and STA can be devices that support multiple links. For example, they can be represented as Access Point Multi-Link Device (AP MLD) and Non-Access Point Multi-Link Device (Non-AP MLD), respectively. AP MLD can represent an access point that supports multi-link communication functions, and non-AP MLD can represent a site that supports multi-link communication functions. For example, in this embodiment of the disclosure, link can represent connection or link; in various embodiments, connection and link can be interchanged.

[0118] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0119] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0120] The embodiments disclosed herein can be applied to Wireless Local Area Networks (WLANs), such as LANs using the 802.11 series of protocols. In a WLAN, a Basic Service Set (BSS) is a fundamental component. An BSS network consists of site devices with some association within a specific coverage area. One type of association is where sites communicate directly with each other in a self-organizing network; this is called an Independent Basic Service Set (IBSS). Another more common scenario is that in a BSS network, there is only one central site dedicated to managing the BSS, called the Access Point (AP) device, and all other STAs in the network are associated with it. Other sites in the BSS network that are not the central site are called terminals, also known as non-AP STAs; terminals and non-AP STAs are collectively referred to as STAs. When describing STAs, it is not necessary to distinguish between terminals and non-AP STAs. Within the same BSS network, due to distance, transmission power, etc., a STA cannot detect other STAs that are far away; they are each other's hidden nodes.

[0121] Next-generation Wi-Fi technologies, such as Ultra High Reliability (UHR), aim to improve the reliability of wireless LAN connections, reduce latency, and lower device-level power consumption. Since most devices supporting the UHR protocol are multi-link communication devices (MLD devices), power-saving mechanisms need further enhancement when UHR APs (Access Points) and UHR STAs (Standard Stations) use multi-link communication for data transmission.

[0122] In related technologies, to further enhance the power-saving mechanism, a Dynamic Power Save (DPS) mode has been proposed. For example, Mobile Access Points (APs) or non-AP STAs can operate in Dynamic Power Save mode. When the communication device operates in Dynamic Power Save mode, it switches to Low Capability (LC) mode. In LC mode, the device's communication capabilities are limited; for example, it only supports single spatial stream and low-rate modulation and coding schemes (MCS) for transmission and reception, with a communication bandwidth of 20MHz, and only supports receiving specific control frames or management frames. Furthermore, if a peer device needs to exchange frames with it, the peer device must send an initial control frame to switch it from Low Capability mode to a higher capability mode, thereby enabling frame exchange with the peer device. The initial control frame is used to instruct the receiving end to switch from a low-capability mode to a high-capability mode in dynamic power saving mode. For example, the initial control frame is transmitted as a non-HT (duplicate) PPDU at a rate of 6Mb / s, 12Mb / s, or 24Mb / s. The initial control frame can be a Buffer Status Report Poll (BSRP) trigger frame or a Multiple User Request to Send (MU-RTS) trigger frame. Taking a site device as an example, when the site device supports dynamic power saving mode, it sends a dynamic power saving mode request to its associated access point device, carrying relevant parameter information for entering dynamic power saving mode, such as the time to enter low-capability mode (including but not limited to start time and duration). After receiving the dynamic power saving mode request and being ready to serve the site device in dynamic power saving mode, the access point device sends a response frame to the site device. When the site device operates in dynamic power-saving mode, the access point device initiates transmission with the site device by sending an initial control frame. Upon receiving the initial control frame, the site device switches from a low-capability mode to a higher-capability state to exchange frames with the wireless site (access point) device that sent the initial control frame. The low-capability mode is a mode with limited operating parameters, such as a 20MHz BW, a single spatial stream, and low-rate, limited PPDU transmission formats like 6Mb / s, 12Mb / s, or 24Mb / s. The high-capability mode is one where at least one operating parameter is higher than in the low-capability mode.

[0123] While the dynamic power-saving mechanism already supports communication devices switching between different capability modes to reduce power consumption, the lack of clear signaling interaction and corresponding state switching procedures when the device needs to turn off the dynamic power-saving mode and restore normal communication capabilities may lead to untimely link switching, unstable communication performance, and affect the overall system efficiency. Therefore, it is necessary to further standardize and improve the process of turning off / out of the dynamic power-saving mode.

[0124] This disclosure provides a communication method, communication device, and communication system for defining the shutdown / exit process in dynamic power-saving mode, ensuring that the device can switch communication capability modes in a timely and stable manner, thereby improving communication reliability and system response efficiency.

[0126] 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 establishing an association with the second device, the first device sends a second wireless frame to the associated second device; wherein the second wireless frame indicates that the first device requests to disable the dynamic power saving mode; correspondingly, the second device receives the second wireless frame sent by the first device and replies to the first device with a first wireless frame after receiving the second wireless frame; wherein the first wireless frame is used to respond to the second wireless frame. The first device can be a UHR non-AP STA or a UHR AP; if the first device is a UHR non-AP STA, the second device is a UHR AP; if the first device is a UHR AP, the second device is a UHR non-AP STA; wherein the second wireless frame includes, but is not limited to, a Dynamic Power Saving Mode Request frame and a Dynamic Power Saving Mode Notification frame; wherein the second wireless frame uses identification information to identify that it is used to request to disable the dynamic power saving mode. Wherein, the second wireless frame indicates that the first device requests to turn off the dynamic power saving mode; wherein, the second device is a device that supports auxiliary dynamic power saving mode; the support for auxiliary dynamic power saving mode means that after the first device enables dynamic power saving mode, it sends an initial control frame to the first device, so that the first device switches from a lower capability communication mode to a higher capability communication mode.

[0128] In this embodiment of the disclosure, after the first device and the second device establish an association, the first device requests the shutdown of the dynamic power saving mode by sending a second wireless frame. After receiving a first wireless frame from the second device in response to the second wireless frame, the first device switches from a first capability communication mode in which the dynamic power saving mode is enabled to a second communication mode in which the dynamic power saving mode is requested to be enabled. This improves the signaling interaction and state switching process for the device to exit the dynamic power saving mode, realizes the timely recovery of communication capabilities, ensures that the device can quickly adapt to normal communication needs after exiting the dynamic power saving mode, improves data transmission efficiency and overall system performance, and avoids communication interruption or service quality degradation caused by capability switching delay.

[0129] In some embodiments, the first capability communication mode and the second capability communication mode include at least one identical operating parameter, and the parameter value of at least one of the operating parameters is lower in the first capability communication mode than in the second capability communication mode.

[0130] Optionally, the first capability communication mode may also be referred to as a first power mode, low-energy communication mode, low-capability communication mode, low-power communication mode, lower capability communication mode, eavesdropping mode, or low-power communication phase, etc., and this disclosure does not limit the name. The second capability communication mode may also be referred to as a high-power mode, high-energy communication mode, high-capability communication mode, high-power communication mode, higher capability communication mode, or high-power communication phase, etc., and this disclosure does not limit the name.

[0131] Optionally, the parameter value of the communication parameter is less than that of the second capability communication mode in the first capability communication mode, which can mean that the communication capability of the communication device in the first capability communication mode is weaker than that in the second capability communication mode.

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

[0133] Optionally, in the first capability communication mode, the device supports a channel bandwidth of 20MHz (Mega Hertz) (i.e., BW = 20MHz), the number of SSs is 1 (i.e., NSS = 1, single spatial stream), and the maximum value of the MCS index is 5, meaning the MCS index value can be any value from 0 to 5, for example, an MCS index value of 5. In the second capability communication mode, the device supports a channel bandwidth greater than or equal to 20MHz, for example, any one or more of 40MHz, 80MHz, 160MHz, or 320MHz, the number of SSs can be greater than or equal to 2, the MCS index can be greater than or equal to 5, etc., without specific limitations.

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

[0135] In this embodiment of the disclosure, after receiving the first wireless frame, the first device switches from the first capability communication mode to the second capability communication mode to restore normal communication capability after the dynamic power saving mode is turned off, so as to support communication with higher bandwidth, higher speed 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] The communication mode in which the first device enables the dynamic power saving mode and does not receive the initial control ICF frame sent by the second device;

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

[0139] In this embodiment of the disclosure, the first capability communication mode includes at least one of the following: firstly, a communication mode in which the first device enables dynamic power saving mode and does not receive an initial control frame (ICF frame) sent by the second device; secondly, a communication mode in which the first device enables dynamic power saving mode and receives an ICF frame sent by the second device. These two scenarios correspond to the initial low capability state of the STA after entering dynamic power saving mode (DPS), and the state of improved communication capability after receiving an ICF frame. Specifically, in the case of not receiving an ICF frame, the first device may only support a channel bandwidth of 20MHz (BW=20MHz), a single spatial stream (NSS=1), and a maximum MCS index of 5 (e.g., MCS=5); while after receiving an ICF frame, its communication capability can be improved to support a channel bandwidth of 40MHz or higher (e.g., BW=40MHz or 80MHz), multiple spatial streams (e.g., NSS=2), and a higher MCS index (e.g., MCS can reach 9 or 11). By distinguishing between these two communication modes, the embodiments of this disclosure 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 dynamic power saving mode, enhancing 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 besides the dynamic power saving mode, such as multi-link communication mode, Wi-Fi mode, Bluetooth mode, etc.

[0141] After receiving a request frame, the access point device associated with the site device replies with a response frame. The site device enters a dynamic power-saving mode (e.g., the first capability communication mode) after receiving the response frame or after a preset time without receiving a response frame. If the site device wants to turn off the dynamic power-saving mode when it has entered the dynamic power-saving mode and has not received an initial control frame from the access point device, it sends a second radio frame and switches from the first capability communication mode to the second capability communication mode after receiving the response frame from the access point device.

[0142] For example, a 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; the site device enters the dynamic power saving mode (e.g., low capability communication mode) after receiving the response frame or after a preset time without receiving the response frame; during this period, the access point device sends an initial control (ICF) frame, instructing the site device to switch from the low capability communication mode to the first capability communication mode (the communication parameters of this capability communication mode are not specifically limited, but are determined according to the communication parameters instructed 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 radio 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 wireless 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 this embodiment of the disclosure, the process of switching from the first capability communication mode to the second capability communication mode may include the following cases one to two:

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

[0148] Scenario 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), then the first device can complete the mode switch after receiving the frame.

[0149] In this embodiment of the disclosure, depending on whether a wireless frame requires an immediate response, the first device switches from a low-capability mode to a high-capability mode at an appropriate time: when a wireless frame requires a response, the first device completes the response first, and then switches modes, avoiding affecting the stability of frame response due to premature switching; when a wireless frame does not require a response, the first device can switch immediately after receiving the frame, reducing waiting time. This processing method improves the flexibility of capability switching of the device in dynamic power-saving mode.

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

[0151] The second wireless frame is used to request the dynamic power saving mode to be turned off;

[0152] Request to disable or exit the dynamic power saving mode indicator;

[0153] Communication session with the second device.

[0154] In this embodiment of the disclosure, the second wireless frame is further used to identify at least one of the following: the frame is used to request the closure of dynamic power saving mode, a request to close or exit dynamic power saving mode identifier, and the communication session to which the frame belongs. For example, the second wireless frame may include a first identifier field indicating that the second wireless frame is used to request the closure of dynamic power saving mode, a second identifier field indicating whether to close (exit) dynamic power saving mode, and a third identifier field identifying the current communication session. Optionally, the first identifier field may be an Ultra-High Reliability Operation (UHR Action) field or a Protected UHR Action field. When the first identifier field is set to a first parameter value, it is used to indicate that the second wireless frame is used to request the closure of dynamic power saving mode. The second identifier field may be a Dynamic Power Saving Mode (DPS Mode) field. When it is set to a second parameter value (e.g., 0), it is used to indicate that the first device closes or exits dynamic power saving mode. The third identifier field may be a Dialog Token field, used to identify the communication session corresponding to the wireless frame. It should be noted that the information carried by the second and third identifier fields can be located in different identifier fields or combined in the same identifier field. This embodiment does not impose specific restrictions on this.

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

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

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

[0158] In this embodiment of the disclosure, the first radio frame is further used to identify at least one of the following: the frame is used in response to a second radio frame; the second radio frame is used for 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 in response to the second radio frame, and a fifth identification field for identifying the current communication session.

[0159] Optionally, the third identification field can be an Ultra-High Reliability Operation (UHR Action) field or a 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 can be a session identifier field (e.g., a Dialog Token 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 and fifth identification fields can be encapsulated in different fields, or they can be combined and carried in the same identification field. This embodiment of the disclosure does not impose specific limitations on this.

[0160] In some embodiments,

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

[0162] Action frames that require an immediate response, and Action frames (No Ack frames) that do not require an immediate response.

[0163] In this embodiment of the disclosure, the first wireless frame can be an action frame requiring an immediate response or an action frame not requiring an immediate response, used by the second device to respond to the request. By distinguishing the response requirements of the action frames, the timing of the 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 wireless frame is used to request the dynamic power saving mode to be turned off;

[0166] Request to disable or exit the dynamic power saving mode indicator;

[0167] Communication session with the second device.

[0168] In this embodiment of the disclosure, the second wireless frame is further used to identify at least one of the following: the frame is used to request the closure of dynamic power saving mode, the frame is used to request the closure or exit of dynamic power saving mode, and the communication session to which the frame belongs. For example, the second wireless frame may include a first identification field indicating that the second wireless frame is used to request the closure of dynamic power saving mode, a second identification field indicating whether the request is to close (exit) 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. 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 identifier field, such as a DPS Mode Request field. When the first identifier field is set to a first parameter value, it is used to indicate that the second radio frame is used to request the disabling of Dynamic Power Saving Mode. The second identifier field can be a Dynamic Power Saving Mode (DPS Mode) field. When it is set to a second parameter value (e.g., 0), it is used to indicate that the first device disables or exits Dynamic Power Saving Mode. The third identifier field can be a 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 identifier field and the third identifier field can be located in different identifier fields, or they can be combined and carried in the same identifier field. This disclosure embodiment does not impose specific limitations on this.

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

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

[0171] Communication session with the first device.

[0172] In this embodiment of the disclosure, the first radio frame is further used to identify at least one of the following: the frame is used to respond to the second radio frame; 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 UHR Action field. 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 (e.g., a Dialog Token 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 and fifth identification fields can be encapsulated in different fields or combined in the same identification field. This embodiment of the disclosure does not impose specific limitations on this.

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

[0175] Optionally, the fourth identifier field included in the first radio frame and the first identifier field identified by the second radio frame are the same identifier field in the dynamic power saving mode notification frame. For example, the dynamic power saving mode notification frame includes a DPS Mode Request identifier field, which is set to 1 in the second radio frame and 0 in the first radio frame; or, the dynamic power saving mode notification frame includes a DPS Mode Response identifier field, which is set to 0 in the second radio frame and 1 in the first radio frame. That is, the dynamic power saving mode notification frame includes either the DPS Mode Request identifier field or the DPS Mode Response identifier field, and different parameter values ​​indicate 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 from those 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 DPS Mode Request and DPS Mode Response identification fields in the dynamic power saving mode notification frame respectively indicate that the dynamic power saving mode notification frame is used for dynamic power saving mode request and dynamic power saving mode response.

[0177] In some embodiments, the access point device determines that the first device switches from a first capability communication mode to a 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 the third radio frame and determines that the first device has switched 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 has switched from the first capability communication mode to the second capability communication mode.

[0180] In this embodiment of the disclosure, the access point device determines when the first device will complete the switch from the first capability communication mode to the second capability communication mode by judging the response requirements of the first radio frame: when the first radio frame indicates that an immediate response is required, the access point device considers the capability switch to be completed after receiving the third radio frame (such as an acknowledgment frame) sent by the first device; if the first radio frame indicates that an immediate response is not required, the first device can be determined to have completed the switch after sending the frame, so that the access point device can accurately judge the status changes of the peer device based on the interaction behavior, which facilitates its reasonable arrangement of subsequent data scheduling or resource allocation, and effectively improves the system's synchronization and communication efficiency.

[0189] Figure 3 is a second interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 3, the embodiments of the present disclosure relate to a communication method, which includes:

[0190] Step 301: The first device 101 sends a second wireless frame; correspondingly, the second device 102 receives the second wireless frame; wherein the second wireless frame is used to request the shutdown of the dynamic power saving mode.

[0191] In this process, the first device sends a second wireless frame to the second device, requesting that the dynamic power saving mode be turned off, and the second device receives the request. This step is used to initiate the exit procedure of the dynamic power saving mode, clarifying that the first device wants 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] In step 302, 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.

[0193] In this process, upon receiving the request, the second device responds by sending a first wireless frame to the first device, which then receives the response frame. This step establishes a control interaction to disable the dynamic power-saving mode, ensuring that the first device performs capability switching upon receiving a clear response, thus guaranteeing the stability of frame exchange.

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

[0195] In this embodiment of the disclosure, if the first radio frame indicates that the first device needs to respond immediately, 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 operation before switching communication capabilities, avoiding response failure due to premature switching.

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

[0197] In this embodiment of the disclosure, after transmitting the third wireless frame, the first device switches from a first capability communication mode to a second capability communication mode, that is, from the communication capability mode in dynamic power saving mode to the communication capability mode when requesting to enable dynamic power saving mode. This step ensures that capability enhancement is performed only after the necessary frame exchange is completed, improves the process of the device disabling dynamic power saving mode, enhances communication efficiency, and reduces latency.

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

[0200] Figure 4 is a third interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 4, the embodiments of the present disclosure relate to a communication method, which includes:

[0201] Step 401, the first device 101 sends a second wireless frame; correspondingly, the second device 102 receives the second wireless frame; wherein, the second wireless frame is used to request the shutdown of the dynamic power saving mode.

[0202] In this process, the first device sends a second wireless frame to the second device, requesting that the dynamic power saving mode be turned off, and the second device receives the request frame. This step is used to initiate the exit procedure of the dynamic power saving mode, clarifying that the first device wants 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] Step 402, 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.

[0204] In this process, upon receiving the request, the second device responds by sending a first wireless frame to the first device, which then receives the response frame. This step establishes a control interaction to disable the dynamic power-saving mode, ensuring that the first device performs capability switching upon receiving a clear response, thus guaranteeing the stability of frame exchange.

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

[0206] If the first wireless frame indicates that the first device does not need to respond immediately, the first device can directly switch from the first capability communication mode to the second capability communication mode after receiving the frame, without waiting for a subsequent response process, which helps to shorten the time delay for the device to recover from a low-power state to a high-performance state.

[0207] The communication method involved in the embodiments of this 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, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0209] The following description uses the first embodiment as an example:

[0210] First embodiment:

[0211] In this embodiment, a site device supporting dynamic power saving mode can send a dynamic power saving mode request to its associated access point device that also supports auxiliary dynamic power saving mode, in order to request enabling or disabling dynamic power saving mode. Specifically, the site device sends a request frame containing a Dynamic Power Saving Mode (DPS Mode) field, with the DPS Mode field set to 1, indicating a request to enter (enable) dynamic power saving mode. After receiving the request and being ready to serve the site device in dynamic power saving mode, the access point device sends 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 (close) dynamic power saving mode. However, in related technologies, the respective operating parameters and actions of the site device making a DPS mode request and the access point device requesting to close dynamic power saving mode after receiving the request are not yet clearly defined. Therefore, signaling and procedures are needed to standardize this.

[0212] To address the aforementioned issues, this disclosure proposes a communication method. Specifically, a site device can send a dynamic power-saving mode request to its associated access point device to disable (exit) the dynamic power-saving mode; the access point device responds to the request to disable the dynamic power-saving mode. Subsequently, the site device determines its operating mode and operating parameters based on the response. Based on this method, the dynamic power-saving mode negotiation process is improved, the site actions under dynamic power-saving mode are standardized, and the dynamic power-saving mode is further improved.

[0213] In some embodiments, the site device sends a second radio frame to its associated access point device, the second radio frame requesting the deactivation (exit) of Dynamic Power Saving Mode (DPS Mode). The second radio frame includes, but is not limited to:

[0214] The first identification field is used to indicate that the second radio frame is a request to disable DPS mode. Optionally, the first identification field can be a UHR Action 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] The second identifier field is used to indicate whether DPS Mode is turned off (exited). Optionally, the second identifier field can be a DPS Mode field, and when the second identifier field is set to a third parameter value (e.g., 0), it indicates that DPS Mode is turned off (exited).

[0216] The third identifier field is used to indicate the current session. Optionally, the third identifier field may be a Dialog Token field.

[0217] In some embodiments, after receiving the second wireless frame, the access point device responds by sending a first wireless frame, the first wireless frame including, but not limited to:

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

[0219] The fifth identifier field is used to indicate the current session. The fourth identifier field is set in the same way as the third identifier field in the second radio frame.

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

[0221] In the second radio frame, the second identifier field is set to the third parameter value. If the first radio frame requests an immediate response (the first radio frame is an Action frame), and the station device sends a third radio frame, it switches from the first capability communication mode under dynamic power saving mode to the second capability communication mode when the station device requests to enable dynamic power saving mode. The third radio frame acknowledges the first radio frame, for example, with 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 receiving the first radio frame, the station device switches from the first capability communication mode under dynamic power saving mode to the second capability communication mode when the station device requests to enable dynamic power saving mode.
