[0031] The embodiments of the present disclosure provide a device power saving method, a communication device, and a communication system.

[0032] In a first aspect, an embodiment of the present disclosure provides a device power saving method, the method comprising:

[0033] The first device does not receive the physical layer start receiving indication information within the first timeout period, or the first device does not send the first radio frame to the second device within the first interval period.

[0034] The first device switches from the first capability mode to the second capability mode within the first transmission delay;

[0035] The first radio frame is used to respond to a first physical layer protocol data unit PPDU sent by the second device, and a value of at least one communication parameter in the second capability mode is smaller than a communication parameter in the first capability mode.

[0036] In the above embodiment, if the first device does not receive the physical layer start receiving indication information within the first timeout period, or the first device does not send the first radio frame to the second device within the first interval period, the first device switches from the first capability mode to the second capability mode within the first transmission delay; wherein, the first radio frame is used to respond to the first physical layer protocol data unit PPDU sent by the second device, and the value of at least one communication parameter in the second capability mode is less than the communication parameter in the first capability mode, thereby realizing timely switching of the device capability mode and reducing device energy consumption.

[0037] In conjunction with some embodiments of the first aspect, in some embodiments, before the first device switches from the first capability mode to the second capability mode within the first transmission delay, the method further includes:

[0038] receiving a second radio frame sent by the second device, where the second radio frame is used to instruct the first device to switch from the second capability mode to the first capability mode;

[0039] The second radio frame includes at least one of the following:

[0040] The Duration field indicates the duration of the channel occupied by the second device for communication with the first device.

[0041] The Padding field is filled to extend the length of the second radio frame.

[0042] In the above embodiment, after receiving the second radio frame sent by the second device, the first device switches from the second capability mode to the first capability mode to initiate frame exchange with the second device. Specifying the communication duration using the Duration field can avoid channel conflicts and improve resource utilization efficiency across the entire network. The Padding field can be used to extend the length of the second radio frame to facilitate capability mode switching for the first device.

[0043] In combination with some embodiments of the first aspect, in some embodiments, after receiving the second radio frame sent by the second device, the method further includes:

[0044] In response to the second radio frame, the first device switches from the second capability mode to the first capability mode, and sends a third radio frame to the second device, where the third radio frame indicates that the first device completes the capability mode switching.

[0045] In the above embodiment, after receiving the second wireless frame, the first device switches from the second capability mode to the first capability mode within a certain period of time, and sends a third wireless frame to the second device, which can effectively notify the second device that the first device has successfully switched to the new capability mode, thereby ensuring that the communication collaboration between the devices remains consistent and efficient.

[0046] In conjunction with some embodiments of the first aspect, in some embodiments, after switching from the second capability mode to the first capability mode, the method includes at least one of the following:

[0047] receiving a second PPDU sent by the second device;

[0048] receiving the first PPDU sent by the second device, and sending a response frame to the second device;

[0049] monitoring the physical layer starting to receive indication information within the first timeout period;

[0050] During the first interval, a first radio frame is sent to the second device.

[0051] In the above embodiment, to ensure that the first device can effectively exchange data and communicate after switching from low-power mode to high-power mode, the first device monitors the physical layer for a start-of-reception indication within a first timeout period. If the second device sends a first PPDU that requires an immediate response from the first device, the first device, after receiving the first PPDU, sends a second radio frame to the second device within a first interval, thereby ensuring timely data transmission and avoiding communication delays.

[0052] In conjunction with some embodiments of the first aspect, in some embodiments, the timing of the first timeout period starts in at least one of the following situations:

[0053] When the first device finishes sending a third PPDU to the second device, the timing of the first timeout period starts; wherein the third PPDU is used to respond to the last of the first PPDUs sent by the second device;

[0054] When the first device receives the last second PPDU sent by the second device, the timing of the first timeout period starts; the second PPDU includes: at least one frame that does not require an immediate response from the first device.

[0055] In the above embodiment, the first timeout period allows the first device to wait for a reasonable amount of time when receiving a frame that does not require an immediate response. If no further communication needs are detected within the first timeout period, the device can promptly enter a low-power mode. This reduces unnecessary energy consumption during the waiting period, particularly when an immediate response is not required, effectively improving energy efficiency.

[0056] In conjunction with some embodiments of the first aspect, in some embodiments,

[0057] The first interval time is a short frame interval SIFS;

[0058] The timing of the first interval time starts when the first device receives the first PPDU sent by the second device.

[0059] In the above embodiment, the first interval is a time period that begins when a device receives a first PPDU from a second device requesting an immediate response. During this time, the first device should promptly send a first radio frame in response. However, if the first device fails to send a response frame within this first interval, this may indicate a communication problem, such as signal interference or processing delay.

[0060] In conjunction with some embodiments of the first aspect, in some embodiments,

[0061] The first transmission delay is the time required for the first device to switch from the second capability mode to the first capability mode; the first transmission delay is the time interval for the first device to inform the second device before the second device sends the second wireless frame.

[0062] In the above embodiment, the first transmission delay may be a time interval that the first device notifies the second device in advance before switching to the first capability mode, so that the second device can adjust its communication time accordingly. By notifying the second device of the transmission delay of the first device in advance, the two devices can better synchronize communication time and reduce waiting and conflicts during the communication process.

[0063] In conjunction with some embodiments of the first aspect, in some embodiments, the first radio frame includes at least one of the following:

[0064] Immediately respond to the immediate response frame and confirm the acknowledgment frame.

[0065] In a second aspect, an embodiment of the present disclosure further provides a communication device, which is a first device. The first device includes a processing module; wherein the first device is used to execute an optional implementation method of the first aspect.

[0066] In a third aspect, an embodiment of the present disclosure further provides a communication device, wherein the communication device is a first device, including:

[0067] one or more processors;

[0068] The first device is used to execute an optional implementation of the first aspect.

[0069] In a fourth aspect, an embodiment of the present disclosure further provides a communication system, including a first device and a second device;

[0070] The first device does not receive the physical layer start reception indication information within the first timeout period, or the first device does not send the first radio frame to the second device within the first interval period.

[0071] The first device switches from the first capability mode to the second capability mode within the first transmission delay;

[0072] The first radio frame is used to respond to a first physical layer protocol data unit PPDU sent by the second device, and a value of at least one communication parameter in the second capability mode is smaller than a communication parameter in the first capability mode.

[0073] In a fifth aspect, an embodiment of the present disclosure further provides a storage medium storing instructions, which, when executed on a communication device, enables the communication device to execute the optional implementation method described in the first aspect.

[0074] In a sixth aspect, an embodiment of the present disclosure proposes a program product. When the program product is executed by a communication device, the communication device executes the method described in the optional implementation manner of the first aspect.

[0075] In a seventh aspect, an embodiment of the present disclosure proposes a computer program, which, when executed on a computer, enables the computer to execute the method described in the optional implementation manner of the first aspect.

[0076] In an eighth aspect, an embodiment of the present disclosure provides a chip or a chip system, which includes a processing circuit configured to execute the method described in the optional implementation of the first and second aspects above.

[0094] Figure 1 It is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0095] like Figure 1 As shown, the communication system 100 includes a first device 101 and a second device 102. The first device 101 can be a station (STA) or an access point (AP). When the first device 101 is a STA, the second device 102 is an AP; when the first device 101 is an AP, the second device 102 is a STA.

[0096] 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 WiFi communication functions. Optionally, the wireless communication terminal is, for example, a mobile phone, a wearable device, an Internet of Things device that supports WiFi communication functions, a car with WiFi communication functions, a smart car, a tablet computer, a computer with wireless transceiver functions, 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.

[0097] Specifically, the station device 101 may be a terminal device or a network device with a wireless fidelity (WiFi) 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.

[0098] 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.

[0099] Optionally, in an embodiment of the present disclosure, the AP and STA may be devices supporting multi-link, for example, they may be respectively represented as a multi-link access point device (AP MLD) and a multi-link site device (Non-Access Point Multi-Link Device, Non-AP MLD); the AP MLD may represent an access point supporting multi-link communication function, and the non-AP MLD may represent a site supporting multi-link communication function.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] Figure 2 FIG. 1 is an interactive diagram of a device power saving method according to an embodiment of the present disclosure. Figure 2 As shown, the above method includes:

[0104] In step 201, the second device 102 sends a second radio frame, where the second radio frame is used to instruct the first device 101 to switch from the second capability mode to the first capability mode. The value of at least one communication parameter in the second capability mode is smaller than the communication parameter in the first capability mode.

[0105] In UHR, power saving mechanisms will be a research focus. To achieve device power saving, in an embodiment of the present disclosure, the second device sends a second radio frame to the first device, and the second radio frame is used to instruct the first device to switch from the second capability mode to the first capability mode. It can be understood that in the embodiment of the present disclosure, "capabilities mode" is equivalent to "capabilities state", and in some embodiments, the two can be interchangeable.

[0106] The first device and the second device may be a STA or an AP. For example, when the first device is a STA, the second device 102 is an AP. STAs include multi-connection station devices (non-AP STAs) attached to non-AP MLDs, and APs include multi-connection access point devices and ultra-high reliability mobile access point devices (UHR mobile APs) attached to AP MLDs. The first device and the second device may be devices that support the UHR transmission protocol or devices that support the Extremely High Throughput (EHT) transmission protocol; for example, when the first device is a non-AP STA, the second device is a UHR mobile AP.

[0107] Among them, the second wireless frame can be an initial control frame (Initiate Control Frame, ICF), the ICF frame can be, for example, a multi-user request to send (Multi-user Request to Send, MU-RTS) frame, or a buffer status report poll (Buffer Status Report Poll, BSRP) frame, or other frames, etc., or a newly defined frame.

[0108] Specifically, at least one communication parameter in the second capability mode is less than the communication parameter in the first capability mode. For example, when the first device is in the second capability mode, its bandwidth (BW) is set to 20 MHz, and it performs transceiver operations with a single spatial stream and a low-rate modulation and coding scheme (MCS). When the first device is in the first capability mode, the BW can be set to greater than 20 MHz, such as 40 MHz, 80 MHz, or 160 MHz, and it performs transceiver operations with multiple spatial streams and a higher-rate MCS.

[0109] Normally, under certain conditions, the UHR device will enter the Low Capabilities Mode (LCM) in the Dynamic Power Save (DPS) mode, such as the Low Power Listening (LPL) mode; in the LPL mode, for example, it maintains a single spatial stream, 20MHz bandwidth, and transmits and receives data at a low rate MCS; in the embodiment of the present disclosure, when the first device is operating in the low capability mode, the second device associated with it can send a second radio frame to the first device, so that the first device switches to the High Capabilities Mode (HCM) or the full capabilities mode, such as the first capabilities mode, after receiving the second radio frame, so as to exchange frames with the second device that sends the second radio frame. It can be seen that in the embodiment of the present disclosure, the first device is allowed to operate in the second capability mode, and when necessary, the second device triggers the switch to the first capability mode, which can effectively reduce the power consumption of the first device. At the same time, when frame exchange is required, the first device is triggered to switch to the high capability mode by the second radio frame to ensure timely and effective transmission of wireless data.

[0110] Step 202 : The first device 101 receives a second radio frame sent by the second device 102 .

[0111] In the embodiment of the present disclosure, after receiving the second radio frame sent by the second device, the first device switches from the second capability mode to the first capability mode to start frame exchange with the second device.

[0112] In some embodiments, the second radio frame includes at least one of the following:

[0113] A Duration field, indicating the duration of the channel occupied by the second device for communication with the first device;

[0114] The Padding field is used to extend the length of the second radio frame.

[0115] In the disclosed embodiment, the Duration field specifies the communication duration, thereby avoiding channel conflicts and improving resource utilization efficiency of the entire network. The Padding field can be used to extend the length of the second radio frame so that the first device can implement capability mode switching.

[0116] In some embodiments, if the first device does not experience the above two communication conditions in the first capability mode (failure to receive the physical layer start receiving indication information within the first timeout period, or failure to send a response frame within the first interval period), the first device will switch from the first capability mode to the second capability mode within the first transmission delay after the duration identified by the Duration field of the second wireless frame arrives. Maintaining the high capability mode within the time period specified by the Duration field ensures that the device can handle all scheduled communication tasks and avoids missing valid data transmission during the channel occupancy time. By switching modes after the duration identified by the Duration field, the first device can ensure that it switches to low power mode only after the scheduled use time of the wireless channel ends, thereby reducing energy waste during the waiting period.

[0117] In step 203 , the first device 101 switches from the second capability mode to the first capability mode in response to the second radio frame, and sends a third radio frame to the second device 102 , where the third radio frame indicates that the first device 101 completes the capability mode switch.

[0118] In an embodiment of the present disclosure, after receiving the second radio frame, the first device switches from the second capability mode to the first capability mode within a certain period of time, and sends a third radio frame to the second device, which can effectively notify the second device that the first device has successfully switched to the new capability mode, thereby ensuring that the communication collaboration between the devices remains consistent and efficient. Among them, the third radio frame can be an Initial Control Response (ICR) frame. The ICR frame notifies the second device that the first device has successfully switched to the new capability mode, and the second device can subsequently transmit PPDU with the first device, thereby ensuring that the communication collaboration between the devices remains consistent and efficient.

[0119] Step 204: The second device 102 receives the third radio frame, where the third radio frame indicates that the first device 101 completes capability mode switching.

[0120] In an embodiment of the present disclosure, the second device receives the third wireless frame, and determines based on the third wireless frame that the first device has completed the capability mode switch, successfully switching from the second capability mode to the first capability mode, so that the second device can promptly understand the capability status changes of the first device, thereby being able to make corresponding adjustments in the communication or collaboration between devices, thereby improving the overall coordination and efficiency of the system.

[0121] In step 205 , the second device 102 sends a first physical layer protocol data unit (PPDU) or a second PPDU.

[0122] In the embodiment of the present disclosure, after the second device receives the third radio frame, the following operations may be performed:

[0123] Operation 1: The second device sends a first PPDU to the first device that requires an immediate response from the first device, wherein the first PPDU requires an immediate response (immediate response or immediate acknowledgement) from the first device.

[0124] Operation 2: The second device sends a second PPDU to the first device, to which the first device does not need to respond immediately. The second PPDU includes at least one frame to which the first device does not need to respond immediately.

[0125] Step 206: The first device 101 receives the first PPDU or the second PPDU.

[0126] In some embodiments, after the first device switches from the second capability mode to the first capability mode, the method includes at least one of the following (1) to (4):

[0127] (1) Receiving a second PPDU sent by the second device; wherein the second PPDU includes: at least one frame that does not require an immediate response from the first device; that is, the second PPDU includes at least one frame that does not require an immediate response from the first device.

[0128] (2) Receive the first PPDU sent by the second device and send a response frame to the second device; the first PPDU requires an immediate response from the first device. In the disclosed embodiment, if the second device sends a first PPDU that requires an immediate response from the first device, the first device sends a second radio frame to the second device within a first interval after receiving the first PPDU, thereby ensuring timely data transmission and avoiding communication delays.

[0129] (3) Within the first timeout period, monitoring the physical layer start reception indication information, where the physical layer start reception indication information is used to indicate a reception status of the first PPDU or the second PPDU at the physical layer of the first device.

[0130] In order to ensure that after the first device switches from low power consumption mode to high power consumption mode, it can effectively perform data exchange and communication operations. The first device listens within the first timeout period whether there is a physical layer start receiving indication information. Among them, the physical layer starts receiving indication information, such as the physical layer starts receiving indication primitive (PHY-RXSTART.indicationprimitive). This indication primitive is a signal sent by the physical layer to the upper layer (for example, the Media Access Control (MAC) layer), indicating that it has detected a valid signal and started receiving data. This is a notification mechanism that informs the upper layer that data has begun to arrive and to prepare to process subsequent frames.

[0131] In some embodiments, the timing of the first timeout period starts in at least one of the following situations:

[0132] Case 1: When the first device finishes sending a third PPDU to the second device, the first timeout period starts; wherein the third PPDU is used to respond to the last of the first PPDUs sent by the second device;

[0133] Case 2: When the first device receives the last second PPDU sent by the second device, the timing of the first timeout period starts; the second PPDU includes: at least one frame that does not require an immediate response from the first device.

[0134] In the disclosed embodiments, there are two possible triggering conditions for the start of the first timeout period. One triggering condition is case 1: the first timeout period begins when the first device completes sending the third PPDU (a response to the last first PPDU sent by the second device) to the second device. This indicates that the system anticipates further communication activity and therefore begins counting down, awaiting subsequent communication instructions. This approach ensures that the first device can accurately time and monitor subsequent communication signals after responding to the second device's communication request. If no further communication signals occur within the first timeout period, the first device can promptly switch to low-power mode, avoiding unnecessary energy consumption. The other triggering condition is case 2: the first timeout period begins when the first device completes receiving the last second PPDU sent by the second device. This second PPDU includes at least one frame that does not require an immediate response from the first device, so the first device does not need to respond immediately. This design allows the first device to have a reasonable waiting time when receiving frames that do not require an immediate response. If no further communication requests are detected within the first timeout period, the device can promptly enter low-power mode. In this way, the system can reduce unnecessary energy consumption during the waiting process, especially when no immediate response is required, effectively improving energy efficiency.

[0135] In some embodiments, the first timeout period is the sum of a short inter frame space (SIFS), a slot time (Slot Time), and a physical layer start reception delay (RxPHYStartDelay). By combining SIFS, Slot Time, and RxPHYStartDelay, the disclosed embodiment allows the first device to accurately calculate the minimum time to wait to ensure that all necessary hardware and protocol delays are taken into account before determining whether a timeout should occur. This avoids unnecessary waiting and ensures that the reception of the physical layer start reception indication information is not abandoned prematurely.

[0136] (4) sending a first wireless frame to the second device within the first interval. In some embodiments, the first interval is one SIFS;

[0137] The timing of the first interval time starts when the first device receives the first PPDU sent by the second device.

[0138] In the disclosed embodiments, the first interval is a time period that begins when a device receives a first PPDU from a second device requesting an immediate response. During this time, the first device should promptly send a first radio frame in response. However, if the first device fails to send a response frame within this first interval, this may indicate a communication issue, such as signal interference or processing delay.

[0139] In the disclosed embodiment, the first interval is set to one SIFS. SIFS is the shortest interval between two frames in wireless communication and is typically used in scenarios requiring a quick response. In the disclosed embodiment, the first interval begins when the first device receives the first PPDU sent by the second device. By setting the first interval to SIFS, the first device can react in a very short time, quickly ending an unnecessary high-energy consumption state and avoiding energy waste caused by waiting for ineffective communication.

[0140] In an embodiment of the present disclosure, if a first device fails to transmit a first radio frame within a first interval after receiving a first PPDU from a second device requesting an immediate response, this indicates that there may be a communication issue, causing the first device to fail to respond in a timely manner. In this case, to prevent the first device from maintaining a high power consumption state during this ineffective communication period, the first device switches from the first capability mode to the second capability mode within a first transmission delay after the first interval expires, thereby avoiding unnecessary energy waste and improving the overall energy efficiency of the system.

[0141] In step 207, if the first device 101 does not receive the physical layer start receiving indication information within the first timeout period, or the first device 101 does not send the first wireless frame to the second device 102 within the first interval period, the first device 101 switches from the first capability mode to the second capability mode within the first transmission delay.

[0142] In an embodiment of the present disclosure, if the first device does not receive the physical layer start receiving indication information within the first timeout period, it means that the physical layer has not detected any valid signal within the expected time, and thus it is considered that the second device has not successfully sent data or the data has not arrived successfully. In this case, if the first device still continues to maintain the first capability mode, it will result in higher capacity consumption of the first device, reducing the transmission efficiency of the system. Therefore, in an embodiment of the present disclosure, if the first device does not receive the physical layer start receiving indication information within the first timeout period, after the first timeout period expires, it switches from the first capability mode to the second capability mode within the first transmission delay, which can significantly reduce the energy consumption of the first device during invalid communication. By switching to the low power consumption mode in a timely manner, the first device is prevented from continuing to maintain a high energy consumption state in the absence of a valid signal, thereby improving the overall energy efficiency of the system, extending the service life of the device, and improving the transmission efficiency of the system.

[0143] In some embodiments, the first transmission delay is the time required for the first device to switch from the second capability mode to the first capability mode; the first transmission delay is the time interval for the first device to inform the second device before the second device sends the second wireless frame.

[0144] In the disclosed embodiments, the first transmission delay refers to the time required for the first device to switch from the low-power second capability mode to the high-power first capability mode. The first transmission delay may be the time interval that the first device notifies the second device in advance before switching to the first capability mode, so that the second device can adjust its communication time accordingly. By notifying the second device of the first device's transmission delay in advance, the two devices can better synchronize their communication time, reducing waiting and conflicts during communication.

[0145] As a first example, see Figure 3 , Figure 3 A specific example of the embodiment of the present disclosure is shown.

[0146] In step 301, at time T1, the second device sends a second radio frame (ICF) to the first device.

[0147] Step 302, at time T2, the first device sends a third wireless frame (ICR) to the second device, notifying the second device through the ICR frame that the first device has successfully switched to high-capability mode.

[0148] Step 303: After the first device switches to the high-capability mode, it exchanges data with the second device.

[0149] Step 304: The first device does not receive the physical layer start receiving indication information within the first timeout period (from time T3 to time T4), or does not receive the physical layer start receiving indication information within the first interval period (for convenience of illustration, Figure 3 In the figure, if the first wireless frame is not sent to the second device within 10 seconds (T3 to T4), the first device switches from high capability mode to low capability mode (Low Capabilities Mode, LCM) within the first transmission delay (T4 to T4).

[0150] As a second example, an embodiment of the present disclosure further provides a device power saving method, including:

[0151] If the first device does not receive the physical layer start receiving indication information within the first timeout period, the first device switches from the first capability mode to the second capability mode within the first transmission delay;

[0152] The value of at least one communication parameter in the second capability mode is smaller than the communication parameter in the first capability mode.

[0153] There are two possible triggering conditions for the start of the first timeout period. One of the triggering conditions is case 1: when the first device completes sending the third PPDU (a response to the last first PPDU sent by the second device) to the second device, the first timeout period begins. If there is no further communication signal within the first timeout period, the first device can promptly switch to low-power mode to avoid unnecessary energy consumption.

[0154] Another condition that triggers the start of the timer is Case 2: When the first device receives the last second PPDU sent by the second device and completes it, the first timeout period begins. Here, the second PPDU includes at least one frame that does not require an immediate response from the first device, so the first device does not need to respond immediately. This design allows the first device to have a reasonable waiting time when receiving frames that do not require an immediate response. If no further communication needs are detected within the first timeout period, the device can enter low-power mode in a timely manner. This allows the system to reduce unnecessary energy consumption during the waiting period, especially in situations where an immediate response is not required, effectively improving energy efficiency.

[0155] As a third example, an embodiment of the present disclosure further provides a device power saving method, including:

[0156] If the first device does not send the first radio frame to the second device within the first interval, the first device switches from the first capability mode to the second capability mode within the first transmission delay;

[0157] The first radio frame is used to respond to a first physical layer protocol data unit PPDU sent by the second device, and a value of at least one communication parameter in the second capability mode is smaller than a communication parameter in the first capability mode.

[0158] The first interval is a time period that begins when a device receives a first PPDU from a second device requesting an immediate response. During this time, the first device should promptly send a first radio frame in response. However, if the first device fails to send a response frame within this first interval, this may indicate a communication issue, such as signal interference or processing delays.

[0159] Optionally, the first interval time can be set to a SIFS, and the timing of the first interval time starts from the moment the first device receives the first PPDU sent by the second device, so that the first device can respond in a very short time, quickly end the unnecessary high energy consumption state, and avoid energy waste caused by waiting for invalid communication.

[0160] In an embodiment of the present disclosure, if the first device does not receive the physical layer start receiving indication information within the first timeout period, or the first device does not send the first wireless frame to the second device within the first interval period, the first device switches from the first capability mode to the second capability mode within the first transmission delay; wherein, the first wireless frame is used to respond to the first physical layer protocol data unit PPDU sent by the second device, and the value of at least one communication parameter in the second capability mode is less than the communication parameter in the first capability mode, thereby realizing timely switching of the device capability mode and reducing device energy consumption.
