[0116] Alternatively, the first device may also be referred to as the first communication device, and the second device may also be referred to as the second communication device.

[0117] In some embodiments, the STA can be a standalone STA or an accessory STA to a site device (non-AP MLD, or simply multi-link site device; AP MLD stands for AP Multi-Link Device, an access point device that supports multi-link communication, or simply multi-link access point device), without limitation. The AP can be a standalone AP or an accessory AP to an access point device (AP MLD) that supports multi-link communication, without limitation.

[0118] In some embodiments, the site equipment includes, 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.

[0119] Specifically, the site equipment can be a terminal device or network device with a Wi-Fi chip. Optionally, the site equipment can 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 the next-generation 802.11 protocol, but is not limited to these.

[0120] In some embodiments, the access point device can be an access point for mobile terminals to access a wired network.

[0121] 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.

[0122] 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.

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.

[0123] 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 an Access Point (AP) device, while other sites in the BSS network that are not APs are called terminals, also known as non-AP STAs. APs and non-AP STAs are collectively referred to as STAs. When describing STAs, it is not necessary to distinguish between APs 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.

[0124] Figure 2 (taking the example of a first device broadcasting a first wireless frame and a second device associated with the first device receiving the first wireless frame; in reality, multiple communication devices capable of receiving the first wireless frame may be included) is an interactive schematic diagram of a communication method according to an embodiment of this disclosure. As shown in Figure 2, the above method includes:

[0125] Step 201, the first device determines the first wireless frame; wherein the first wireless frame includes first identification information, the first identification information identifying: information related to the dynamic power saving mode of the first device.

[0126] 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.

[0127] Currently, to further enhance power saving mechanisms, a dynamic power saving mode suitable for Mobile APs or non-AP STAs has been proposed. For example, Mobile APs (Mobile Access Point devices) or non-AP STAs can operate in Dynamic Power Save (DPS) mode. When the communication device operates in a lower capability mode, its supported operating bandwidth is 20MHz, and it only supports single spatial stream and low-rate MCS (Modulation and Coding Scheme) for transmission and reception, and only supports receiving specific control frames or management frames. Furthermore, the communication device operating in the lower capability mode can switch to a higher capability mode to complete frame exchange only after receiving a radio frame sent by its associated communication device (hereinafter referred to as "associated device"). This radio 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, this radio frame can be an initial control frame, or ICF frame for short. An initial control frame can be, for example, a MU-RTS frame (multiple user request to send) or a buffer status report poll trigger frame (BSRP trigger frame). After the current TXOP ends upon receiving the trigger frame, the communication device will switch back to a lower capability mode within a certain period to maintain a lower operating state with lower communication parameter values ​​and reduce device power consumption.

[0128] While the above methods can effectively reduce the energy consumption of communication equipment to some extent while maintaining dynamic power-saving mode, several problems still remain. For example,

[0129] (1) How to negotiate DPS mode between devices, such as enabling or disabling DPS mode. For example, when a communication device enables dynamic power saving mode, its associated devices cannot know the current communication mode of the communication device, resulting in reduced communication efficiency. For example, if a communication device is in a low-capacity communication mode, and its associated devices communicate with it, the communication device may not be able to receive the data sent by its associated devices, resulting in packet loss, transmission failure, etc.

[0130] (2) For communication devices (e.g., UHR Mobile AP or non-AP STA), there are multiple ways to enable or enter DPS mode, and further research is needed on which method to use to enter (enable) DPS mode.

[0131] (3) When to enable or disable DPS mode for communication devices also needs to be discussed. For example, if a communication device is in a low-capacity communication mode, a device that has not been associated with the communication device may not be able to associate with it; and as mentioned above, if a device that has been associated with the communication device is unaware that the communication device has entered DPS mode, it may cause communication failure later.

[0132] Based on one or more of the problems mentioned above, the current dynamic power-saving mechanism needs to be improved.

[0133] In this embodiment, the first device determines a first wireless frame and carries information about its dynamic power-saving mode through a first identification information in the first wireless frame. Thus, by sending the first wireless frame, the first device can transmit this information, allowing other devices to determine when and how to associate with it, or to determine the current communication mode of the first device and, based on that mode, determine the communication parameters for communicating with it. This achieves the goal of minimizing the first device's power consumption while improving the communication efficiency and reliability between the first device and other devices.

[0134] Optionally, the first device may include, but is not limited to, a UHR Mobile AP (UHR mobile access point device, i.e., a mobile access point device that supports the UHR protocol) and a non-AP STA.

[0135] In some embodiments, the relevant information of the dynamic power saving mode of the first device may include: time information and / or enable information of the dynamic power saving mode of the first device; the time information may include the start time of the first device entering the dynamic power saving mode and / or the target duration of the first device being in the dynamic power saving mode; the enable information may include whether the first device enables the dynamic power saving mode.

[0136] Optionally, the start time for the first device to enter the dynamic power saving mode is the time when the first device turns on (or enters) the dynamic power saving mode. In other words, when the start time is reached, the first device enters the dynamic power saving mode.

[0137] Optionally, the target duration for the first device to be in dynamic power-saving mode is the duration during which the first device remains in dynamic power-saving mode after entering it. In other words, the target duration is the time from when the first device enters dynamic power-saving mode until it turns off. Based on this, it can be understood that the first device turns off dynamic power-saving mode after the cumulative time reaches the target duration, starting from when the first device enters dynamic power-saving mode.

[0138] Optionally, the first device enables dynamic power saving mode, that is, the communication mode of the first device is dynamic power saving mode, that is, the first device has turned on (i.e. entered) dynamic power saving mode; the first device does not enable dynamic power saving mode, that is, the communication mode of the first device is not dynamic power saving mode, that is, the first device has turned off dynamic power saving mode.

[0139] Optionally, the information related to the dynamic power saving mode of the first device may include only: the time information of the dynamic power saving mode of the first device; or only the enabling information of the first device; or both the time information of the dynamic power saving mode of the first device and the enabling information of the first device.

[0140] In some embodiments, the dynamic power-saving mode includes switching between a first capability communication mode and a third capability communication mode;

[0141] The first capability communication mode and the third capability communication mode include at least one identical communication parameter, wherein the parameter value of the communication parameter is smaller in the first capability communication mode than in the third capability communication mode.

[0142] Optionally, switching can be performed between a first capability communication mode and a third capability communication mode, i.e., switching from the first capability communication mode to the third capability communication mode, and vice versa. For example, in dynamic power-saving mode, when no frame exchange is performed, the system is in the first capability communication mode, and when frame exchange is performed in dynamic power-saving mode, the system is in the third capability communication mode.

[0143] 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 third 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.

[0144] Optionally, in order to be compatible with the current PS (power saving) mode, the first capability communication mode may include the Doze State (also known as the hibernation state) corresponding to the PS mode, and the third capability communication mode may include the Awake State (wake-up state) corresponding to the PS mode. This disclosure does not specifically limit this.

[0145] Optionally, the parameter value of the communication parameter is less than that of the third 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 third capability communication mode.

[0146] Optionally, during data communication by the first device, i.e., when the first device disables dynamic power-saving mode, the communication mode of the first device may include a second capability communication mode. Optionally, the second capability communication mode may include Active Mode corresponding to PS mode.

[0147] Optionally, the first capability communication mode and the second capability communication mode include at least one identical communication parameter, wherein the parameter value in the first capability communication mode is weaker than that in the second capability communication mode.

[0148] Optionally, the second capability communication mode may include at least one of the same communication parameters as the third capability communication mode, and the value of this communication parameter may be greater than or equal to that in the second capability communication mode than in the third capability communication mode. That is, the communication capability of the communication device in the first capability communication mode is weaker than that in the second capability communication mode, and the communication capability in the first capability communication mode is weaker than that in the third capability communication mode. However, the communication capability of the communication device in the second capability communication mode may be stronger than or equal to that in the third capability communication mode.

[0149] Optionally, the communication parameters corresponding to the first, second, or third capability communication modes may include, but are not limited to, channel bandwidth (BW), supported MCS methods, NSS (number of spatial streams), and transmission rate. The following explanation uses the communication parameter values ​​of the first device in the first and third capability communication modes as examples.

[0150] 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 third 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. The specific parameter values ​​can be determined based on the communication parameter values ​​supported by the second device 102 or based on the communication requirements between the second device 102 and the first device 101.

[0151] Optionally, in one communication mode, the MCS information supported by the device is associated with multiple communication parameters. For example, the communication parameters associated with the MCS information may include, but are not limited to: NSS, the modulation scheme supported by each spatial stream, coding rate, BW, device transmission resource type [e.g., Resource Unit RU, Multiple Resource Unit (MRU), Distributed Resource Unit (dRU), UEQM, etc.], whether the device supports BW punctured channel pattern, and at least one of the punctured channel density supported by the device.

[0152] For example, regarding each communication parameter, does the device support its specific parameter values? For instance, for NSS, the maximum NSS supported by the device could be 4, 8, or 16. Taking modulation schemes as an example, the modulation schemes supported by a spatial stream supported by the device could be at least one of Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), Quadrature Amplitude Modulation (QAM), 64-QAM, 256-QAM, 1024-QAM, and 4096-QAM. Taking coding rate as an example, the coding rate supported by a spatial stream supported by the device could be 1 / 2, 2 / 3, 3 / 4, or 5 / 6. Taking BW as an example, the BW supported by the device could be at least one of 20MHz, 40MHz, 80MHz, 160MHz, and 320MHz. When the device supports BW punch channel mode, the punch channel density supported by the device may be at least one of 20MHz, 40MHz, 80MHz, 160MHz, and 320MHz.

[0153] For a given device, the MCS information it supports can be found in Table 1.

[0154] Table 1

[0155] As shown in Table 1, n, n+1, n+2, n+3, n+4, etc., are merely examples used to distinguish the differences between each row. Specific values ​​need to be adjusted according to the actual situation. In each row, the NSS, modulation, coding rate, transmission resource type, BW, whether puncturing is supported, and puncturing channel density corresponding to the device can be arbitrarily combined, and the corresponding MCS index value will differ under different combinations. For example, in the second row, the MCS index values ​​corresponding to different combinations can specifically be t, t+1, t+2, ..., etc.

[0156] Optionally, the first radio frame may include, but is not limited to, a broadcast management frame or an action frame.

[0157] Optionally, broadcast management frames may include, but are not limited to, Beacon frames and Probe Response frames.

[0158] Optionally, the broadcast management frame may include a UHR Operation element, which includes a DPS Operation Parameter field, with first identification information carried in the DPS Operation Parameter field.

[0159] Optionally, if the first radio frame is a broadcast management frame, the first radio frame can be transmitted via broadcast.

[0160] Optionally, the action frame may include a DPS Operation Parameter field, in which first identification information is carried.

[0161] In some embodiments, the first wireless frame may further include a DPS Support flag (the DPS Support flag can indicate whether the first device supports dynamic power saving mode).

[0162] Optionally, if the DPS Support flag is set to the first parameter value, it indicates that the first device supports dynamic power saving mode; if the DPS Support flag is set to the second parameter value, it indicates that the first device does not support dynamic power saving mode.

[0163] Optionally, the first parameter value can be "1" and the second parameter value can be "0". That is, when the DPS Support flag is set to "1", it indicates that the first device supports dynamic power saving mode; when the DPS Support flag is set to "0", it indicates that the first device does not support dynamic power saving mode.

[0164] In some embodiments, the DPS Operation Parameters field may also carry communication parameters of the first device in dynamic power-saving mode.

[0165] When the first radio frame is an action frame, the RA (Receive Address) of the DPS Operation Notification field can be set to the broadcast address, meaning that the first radio frame can be sent via broadcast.

[0166] In some embodiments, the first identification information includes a first identification field and / or a second identification field.

[0167] The first identifier field identifies the start time;

[0168] The second identifier field identifies the target duration.

[0169] Optionally, in the first wireless frame, specifically in the first identification information of the first wireless frame, the start time of the first device entering the dynamic power saving mode can be carried by the first identification field, and the target duration of the first device being in the dynamic power saving mode can be carried by the second identification field.

[0170] Optionally, the first identification information may include only the first identification field, or it may include both the first and second identification fields, or it may include only the second identification field.

[0171] In some embodiments, the first identification information further includes a second identification bit, which identifies the enable information of the first device.

[0172] Optionally, the second flag may include the DPS Enable flag.

[0173] Optionally, when the DPS Enable flag is set to the third parameter value, it indicates that the first device enables dynamic power saving mode; when the DPS Enable flag is set to the fourth parameter value, it indicates that the first device disables dynamic power saving mode.

[0174] Optionally, the third parameter value can be "1" and the fourth parameter value can be "0". That is, when the DPS Enable flag is set to "1", it indicates that the first device enables DPS mode (i.e., turns on DPS mode); when the DPS Enable flag is set to "0", it indicates that the first device turns off DPS mode.

[0175] Optionally, the first identification information may include only the second identification bit, or it may include the first identification field and the second identification bit, or it may include the first identification field, the second identification field and the second identification bit, or it may include the second identification field and the second identification bit.

[0176] Step 202: The first device sends the first wireless frame.

[0177] In some embodiments, the first device sending a first wireless frame may include: the first device broadcasting the first wireless frame. Accordingly, a second device already associated with the first device may receive the first wireless frame sent by the first device, and a second device not yet associated with the first device may also receive the first wireless frame sent by the first device.

[0178] Optionally, after the first device sends the first wireless frame, the communication mode of the first device can be determined based on the information related to the dynamic power-saving mode of the first device carried in the first identification information. Specifically, this may include at least one of the following: ① step 301, ② step 401, ③ a combination of steps 501 to 503, ④ a combination of steps 601 to 603, and step 701.

[0179] Referring to Figure 3, in step 301, when the aforementioned start time arrives, the first device activates the dynamic power-saving mode.

[0180] Optionally, "enabling dynamic power saving mode" can also be referred to as "entering dynamic power saving mode", and this disclosure does not limit this.

[0181] In some embodiments, enabling a dynamic power-saving mode for the first device may include: the first device entering a first capability communication mode.

[0182] Optionally, regardless of whether the first wireless frame indicates a start time, the dynamic power saving mode can correspond to a start time. When the start time is reached, the first device starts the dynamic power saving mode, for example, the first device enters the first capability communication mode.

[0183] Optionally, after the first device enables the dynamic power saving mode, the first device can be in the first capability communication mode.

[0184] Referring to Figure 4, in step 401, when the first device is in dynamic power saving mode for the duration of the aforementioned target duration, the first device turns off dynamic power saving mode.

[0185] In some embodiments, turning off the dynamic power saving mode of the first device may include switching from a first capability communication mode to a second capability communication mode.

[0186] Optionally, the time from when the first device starts the dynamic power saving mode to the current time can be calculated as the "target duration of the first device in dynamic power saving mode".

[0187] Optionally, after the first device activates the dynamic power-saving mode, the first device can be in the first capability communication mode. If the first device remains in the first capability communication mode for a duration equal to the target duration indicated by the second identifier field, the first device deactivates the dynamic power-saving mode and switches from the first capability communication mode to the second capability communication mode. That is, the combination of steps 201, 202, 301, and 401 can be implemented as an independent embodiment.

[0188] Optionally, regardless of whether the first wireless frame indicates a target duration, the dynamic power-saving mode can correspond to a target duration. When the first device maintains the first capability communication mode for the duration that target duration is reached, the first device turns off the dynamic power-saving mode, for example, the first device switches to the second capability communication mode. For example, the first identification field and the second identification field can be carried in the first identification information, and the combined steps of steps 301 and 401 can be performed.

[0189] Optionally, regardless of whether the first wireless frame indicates a target duration, the dynamic power saving mode may not correspond to a target duration. When other situations require the dynamic power saving mode to be turned off are met, the first device turns off the dynamic power saving mode, such as when the first device switches to the second capability communication mode.

[0190] Optionally, regardless of whether the first wireless frame indicates a target duration, the dynamic power saving mode can correspond to a target duration. As long as any of the following conditions are met, such as when the dynamic power saving mode needs to be turned off or when the first device maintains the first capability communication mode for a duration that reaches the target duration, the first device turns off the dynamic power saving mode, for example, when the first device switches to the second capability communication mode.

[0191] For example, other situations where the dynamic power saving mode needs to be turned off may include the first device sending a second wireless frame, etc., which are not limited in this application embodiment.

[0192] In some embodiments, referring to FIG5, in step 501, when the first device is in dynamic power saving mode, the first device determines a second wireless frame; wherein, the second wireless frame includes second identification information; the second identification information indicates that the first device has turned off the dynamic power saving mode.

[0193] Optionally, the frame type of the second wireless frame may be the same as or different from that of the first wireless frame, as detailed in the foregoing description of the first wireless frame, which will not be repeated here.

[0194] Optionally, the second wireless frame may include, but is not limited to, a broadcast management frame or an action frame.

[0195] Optionally, broadcast management frames may include, but are not limited to, Beacon frames and Probe Response frames.

[0196] Optionally, the broadcast management frame may include a UHR Operation element, which includes a DPS Operation Parameter field, and a second identification information is carried in the DPS Operation Parameter field.

[0197] Optionally, if the second radio frame is a broadcast management frame, the second radio frame can be transmitted via broadcast.

[0198] Optionally, the action frame may include a DPS Operation Parameter field, in which second identification information is carried.

[0199] In some embodiments, the second identification information further includes a first identification bit, which indicates that the first device has turned off the dynamic power saving mode.

[0200] Optionally, the first flag bit can be the same as the second flag bit, that is, the first flag bit can be the DPS Enable flag bit, and when the DPS Enable flag bit is set to the fourth parameter value, it indicates that the first device has turned off the dynamic power saving mode.

[0201] In step 502, the first device sends a second radio frame to the second device. Correspondingly, the second device receives the second radio frame sent by the first device.

[0202] Step 503: The first device turns off the dynamic power saving mode.

[0203] Optionally, after the first device activates the dynamic power-saving mode, the first device can be in a first capability communication mode. Furthermore, the first device can determine the second wireless frame while in the first capability communication mode. That is, the combination of steps 201, 202, 301, 501, 502, and 503 can be implemented as an independent embodiment.

[0204] Optionally, in this embodiment of the disclosure, the combined steps of steps 501, 502, and 503 (the first device sends a second wireless frame to the second device and then disables the dynamic power saving mode) and step 401 (the first device remains in dynamic power saving mode for a duration equal to the target duration indicated by the second identifier field, and then disables the dynamic power saving mode) can both be considered as steps for the first device to disable the dynamic power saving mode. Whether the former (the combined steps of steps 501, 502, and 503) or the latter (step 401) is executed, the dynamic power saving mode can be disabled. In practical applications, the timing of the former and the latter can be used to determine whether the dynamic power saving mode is disabled. That is, this embodiment of the disclosure does not limit the execution order of steps 401 and 501; regardless of which step is executed first, the first device will disable the dynamic power saving mode.

[0205] Optionally, if the first identification information includes a first identification field and a second identification field, and the duration of the first device in dynamic power-saving mode has not reached the target duration indicated by the second identification field, then a combination of steps 501, 502, and 503 may be performed. Alternatively, if the first identification information does not include a second identification field, then a combination of steps 501, 502, and 503 may be performed.

[0206] In some embodiments, referring to FIG6, in step 601, the second device determines a third wireless frame; wherein the third wireless frame is used to trigger the first device to switch capability communication modes, or to trigger the first device and the second device to exchange frames; wherein the second device is associated with the first device.

[0207] Optionally, the third radio frame may include, but is not limited to, an initial control frame (ICF frame), a MU-RTS frame (multiple user request to send), or a buffer status report poll trigger frame (BSRP trigger frame).

[0208] Optionally, if the third radio frame is used to trigger the first device to switch capability communication modes, the first device can be triggered to switch from the first capability communication mode to the frame exchange preparation state (i.e., the third capability communication mode).

[0209] Optionally, when the third wireless frame is used to trigger frame exchange between the first device and the second device, the first device can be implicitly triggered to switch from the first capability communication mode to the frame exchange preparation state, and the frame exchange operation between the first device and the second device can be completed in the frame exchange preparation state.

[0210] In step 602, the second device sends a third radio frame to the first device. Correspondingly, the first device receives the third radio frame sent by the second device.

[0211] Optionally, the second device may send a third wireless frame to the first device before the duration indicated by the second identifier field expires or before the first device sends a second wireless frame to the second device, that is, during the period when the first device is in dynamic power saving mode.

[0212] Step 603: The first device and the second device participate in frame exchange.

[0213] Optionally, the first device and the second device participate in frame exchange, that is, the first device and the second device perform frame exchange operations, that is, the first device and the second device perform data transmission operations. For example, the second device sends a Wi-Fi data frame (i.e. a data frame based on the Wi-Fi communication protocol) to the first device, and the first device sends a Wi-Fi data frame to the second device.

[0214] Optionally, when the first device is in dynamic power saving mode, if the first device is triggered to exchange frames with the second device (for example, the first device receives a third wireless frame), the dynamic power saving mode of the first device is not turned off. Instead, it can switch from the first capability communication mode to the third capability communication mode, complete the frame exchange in the third capability communication mode, and then determine whether to restore the first capability communication mode. For example, if the first device is in dynamic power saving mode for a target duration, it is determined that the dynamic power saving mode is turned off, or if the first device is in dynamic power saving mode for a target duration, it is switched to the first capability communication mode.

[0215] Optionally, while operating in DPS mode, the first device receives a third wireless frame, switches to the third capability communication mode and completes frame exchange, then switches to the first capability communication mode, and will turn off DPS mode after the target duration is reached.

[0216] Optionally, while operating in DPS mode, after the first device receives the third wireless frame, switches to the third capability communication mode and completes frame exchange, it sends the second wireless frame and turns off the DPS mode.

[0217] Optionally, the first device and the second device participating in frame exchange may include: after the first device receives a third wireless frame sent by the second device, it switches to the third capability communication mode to participate in frame exchange.

[0218] Optionally, if the first identification information includes a first identification field and a second identification field, and the duration of the first device in dynamic power-saving mode has not reached the target duration indicated by the second identification field, then steps 601, 602, and 603 can be combined. Alternatively, if the first identification information does not include a second identification field, then steps 601, 602, and 603 can be combined.

[0219] Optionally, referring to Figure 7, after step 603, the above steps may further include step 701, wherein step 701 includes at least one of the following:

[0220] When the first device and the second device complete frame exchange, and the first device has not been in dynamic power saving mode for the target duration, the first device switches to the first capability communication mode.

[0221] When the first device and the second device complete frame exchange, and the first device has been in dynamic power saving mode for a period of time that reaches the target duration, the first device turns off dynamic power saving mode.

[0222] Optionally, in step 701, the method for determining the duration of the first device in dynamic power-saving mode remains consistent with the above description. That is, after the first device enables dynamic power-saving mode, if the first device exchanges frames with the second device, the duration of the frame exchange between the first device and the second device is included in the duration of the first device in dynamic power-saving mode. Based on whether the duration of the first device in dynamic power-saving mode reaches the target duration, it is determined whether the first device switches to the first capability communication mode or disables dynamic power-saving mode.

[0223] Optionally, if the first device and the second device complete frame exchange, and the first device has not reached the target duration in dynamic power saving mode, the first device can continue timing if it switches to the first capability communication mode. The dynamic power saving mode will then be turned off once the target duration is reached. Alternatively, if the first device and the second device complete frame exchange, and the first device has not reached the target duration in dynamic power saving mode, the dynamic power saving mode can still be turned off by sending a second wireless frame if the first device switches to the first capability communication mode.

[0224] In step 601, the process can be performed after the first device has enabled the dynamic power-saving mode. That is, the combination of steps 201, 202, 301, 601, 602, and 603 can be implemented as an independent embodiment.

[0225] Optionally, in this embodiment of the disclosure, the combination of steps 601, 602, and 603, as well as the combination of step 401, can be implemented as independent embodiments. That is, in step 701 above, "when the first device and the second device complete frame exchange, and the first device is in dynamic power-saving mode for less than the target duration, the first device switches to the first capability communication mode" and "when the first device and the second device complete frame exchange, and the first device is in dynamic power-saving mode for less than the target duration, if the first device switches to the first capability communication mode, it can still..." "Continue timing, and after the duration of the first device in dynamic power saving mode reaches the target duration, then turn off the dynamic power saving mode"; the combination of steps 601, 602 and 603 and the combination of steps 501, 502 and 503 can also be implemented as independent embodiments, that is, "if the first device and the second device complete frame exchange, and the duration of the first device in dynamic power saving mode has not reached the target duration, if the first device switches to the first capability communication mode, the dynamic power saving mode can still be turned off by sending a second wireless frame by the first device."

[0226] Optionally, if the first identification information includes a first identification field and a second identification field, and the duration of the first device in dynamic power-saving mode has not reached the target duration indicated by the second identification field, then a combination of steps 601, 602, 603, and 701 can be executed. Alternatively, if the first identification information does not include a second identification field, then a combination of steps 601, 602, and 603, as well as a combination of steps 501, 502, and 503, can be executed.

[0227] In some embodiments, referring to FIG8, step 801, the dynamic power saving mode is maintained if the first device is in dynamic power saving mode for less than the target duration, or if the first device does not receive the third wireless frame sent by the second device, or if the first device does not send the second wireless frame to the second device.

[0228] For example, if a target duration is set for the dynamic power saving mode, the dynamic power saving mode can be maintained when the duration of the first device in dynamic power saving mode does not reach the target duration; for example, if a target duration is set for the dynamic power saving mode, and sending a second wireless frame is also used as a trigger condition for turning off the dynamic power saving mode, the dynamic power saving mode can be maintained when the duration of the first device in dynamic power saving mode does not reach the target duration and no second wireless frame is sent.

[0229] For example, if sending a second wireless frame is used as a trigger condition to turn off the dynamic power saving mode, then the dynamic power saving mode can be maintained when the first device does not send a second wireless frame.

[0230] For example, if the dynamic power saving mode is set with a target duration, and receiving a third wireless frame is also used as a trigger condition to turn off the dynamic power saving mode, then the dynamic power saving mode can be maintained when the first device is in the dynamic power saving mode for less than the target duration and no third wireless frame is received.

[0231] Optionally, step 801 can be executed after the first device has enabled dynamic power saving mode. That is, the combination of steps 201, 202, 301, and 801 can be implemented as an independent embodiment.

[0232] Optionally, step 801 can also be implemented as an independent embodiment, combining steps 401, 501, 502, and 503, 601, 602, and 603, or 601, 602, 603, and 701. That is, in these embodiments, as long as at least one of the following conditions is met—that is, the first device maintains the dynamic power-saving mode, i.e., remains in the first capability communication mode—the dynamic power-saving mode is maintained.

[0233] Optionally, referring to the embodiment shown in FIG9, it may include: step 201, step 202, step 301, step 801 and step 401.

[0234] Step 201, the first device determines the first wireless frame; wherein the first wireless frame includes first identification information, the first identification information identifying: information related to the dynamic power saving mode of the first device.

[0235] Step 202: The first device sends the first wireless frame. Correspondingly, the second device receives the first wireless frame sent by the first device.

[0236] Step 301: When the start time for the first device to enter dynamic power saving mode arrives, the first device activates dynamic power saving mode.

[0237] Step 801: The first device maintains dynamic power saving mode.

[0238] Step 401: When the duration of the first device in dynamic power saving mode reaches the target duration of the first device in dynamic power saving mode, the first device turns off dynamic power saving mode.

[0239] Optionally, referring to the embodiment shown in FIG10, steps 201, 202, 301, 801, 501, 502 and 503 may be included.

[0240] Step 201, the first device determines the first wireless frame; wherein the first wireless frame includes first identification information, the first identification information identifying: information related to the dynamic power saving mode of the first device.

[0241] Step 202: The first device sends the first wireless frame. Correspondingly, the second device receives the first wireless frame sent by the first device.

[0242] Step 301: When the start time for the first device to enter dynamic power saving mode arrives, the first device activates dynamic power saving mode.

[0243] Step 801: The first device maintains dynamic power saving mode.

[0270] This disclosure provides a dynamic power-saving method applicable to communication devices (specifically, a UHR Mobile AP). Specifically, a UHR Mobile AP supporting DPS mode can announce its DPS mode information (i.e., the aforementioned first identification information) via a broadcast frame. This DPS mode information includes, but is not limited to, the start time of the UHR Mobile AP entering DPS mode and / or the duration of the UHR Mobile AP in DPS mode. When an unassociated device (i.e., a communication device not associated with the UHR Mobile AP) wishes to associate with the UHR Mobile AP, it can complete the association before the start time of entering DPS mode. An already associated device (i.e., a communication device already associated with the UHR Mobile AP) can initiate frame exchange with the UHR Mobile AP via an initial control frame while the UHR Mobile AP is in DPS mode. Furthermore, the UHR Mobile AP can also announce the shutdown or early shutdown of DPS mode via a broadcast frame. Based on this method, the current dynamic power-saving mode negotiation method and process are improved, providing a foundation for reducing the power consumption of UHR Mobile AP devices. The specific process of this dynamic power-saving method for UHR Mobile AP is as follows:

[0271] 1. A UHR Mobile AP supporting DPS mode transmits a first radio frame; wherein, the first radio frame carries first identification information, the first identification information being used to indicate relevant information for the UHR Mobile AP to enter DPS mode (i.e., the aforementioned DPS mode information and first identification information). The relevant information for DPS mode includes, but is not limited to, the following:

[0272] (1) DPS Enable flag indicates whether the UHR Mobile AP enables DPS mode. When the DPS Enable flag is set to 1, DPS mode is enabled; otherwise, DPS mode is disabled.

[0273] (2) First identifier field, which identifies the start time of the UHR Mobile AP entering (enabling) DPS;

[0274] (3) Optional second identification field, which identifies the duration of time the UHR Mobile AP operates in DPS after the time indicated by the first identification field (i.e. the duration of time the first device is in dynamic power saving mode).

[0275] Optionally, the first radio frame can be a broadcast management frame: a Beacon frame or a Probe Response frame. Optionally, the first identification field and an optional second identification field can be included in the UHR Operation element of the Beacon frame or the Probe Response frame. Optionally, the UHR Operation element includes a DPS Operation Parameter field, and the first identification field and the optional second identification field are included in the DPS Operation Parameter field.

[0276] Optionally, the first radio frame may also be an action frame, which includes a DPS Operation Notification field, wherein the RA (Receive Address) of the DPS Operation Notification field is set to the broadcast address. Optionally, the DPS Operation Notification includes a DPS Operation Parameter field, wherein a first identification field and an optional second identification field are included in the DPS Operation Parameter field.

[0277] 2. After the UHR Mobile AP sends the first radio frame, it performs the following operations:

[0278] A. After the time indicated by the first identifier field in the first radio frame begins, enter (enable) DPS mode;

[0279] a) If the first radio frame contains an optional second identifier field, the UHR Mobile AP enters (enables) DPS mode at the time indicated by the first identifier field, and then disables DPS mode after the time indicated by the second identifier field has elapsed.

[0280] b) If the first radio frame does not contain an optional second identification field, the UHR Mobile AP enters (on) mode after the start of the first identification field indication time, and turns off DPS mode after sending the second radio frame; wherein the second radio frame contains second identification information, which is used to instruct the UHR Mobile AP to turn off DPS mode.

[0281] Optionally, the second radio frame includes a DPS Enable identifier, and second identification information is carried in the DPS Enable identifier. When the DPS Enable identifier is set to 0, the second identification information is used to instruct the UHR Mobile AP to turn off DPS mode.

[0282] Optionally, either 2-a) or 2-b), whichever occurs first, the UHR Mobile AP will disable DPS mode.

[0283] Optionally, the second radio frame may be a Beacon frame, or the second radio frame may be a radio frame (e.g., an action frame) in which the RA is set to a broadcast address and includes the DPS Operation Notification field.

[0284] Optionally, the second radio frame includes a DPS Operation Parameter field, in which the DPS Enable identifier is included.

[0285] B. During the period from entering (enabling) DPS mode to disabling DPS mode, the UHR Mobile AP operates in a low-capability communication mode unless it receives an initial control frame from its associated device.

[0286] C. During the period from entering (enabling) DPS mode to disabling DPS mode, after the UHR Mobile AP receives the initial control frame sent by its associated device, it switches to high-capability communication mode and participates in frame exchange. After the frame exchange is completed, it switches to low-capability communication mode.

[0287] 3. After the UHR Mobile AP enters the DPS mode indicated by the first radio frame, if the associated device needs to exchange frames with the UHR Mobile AP after successfully competing for the channel, it can send an initial control frame to the UHR Mobile AP. The initial control frame is used to instruct the UHR Mobile AP to switch from the low-capability communication mode to the high-capability communication mode.

[0288] Based on the above dynamic power saving method applicable to UHR Mobile AP, the dynamic power saving mode negotiation method and process can be improved, providing a foundation for reducing the power consumption of UHR Mobile AP terminal devices.
