[0068] Optionally, the embodiment of the present disclosure does not limit the number of links established between the multi-link station device 101 and the multi-link access point device 102, and the number can be determined according to actual conditions.

[0069] In some embodiments, an access point device (AP) can be an access point for a mobile terminal 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.

[0071] Specifically, the station device can be a terminal device or network device with a Wireless Fidelity (Wi-Fi) chip. Optionally, the relay device 102 and the station device 103 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 support the next generation 802.11 protocol, but are not limited thereto.

[0072] 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.

[0073] 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.

[0074] The various embodiments of the present disclosure can be applied to a wireless local area network (WLAN), such as a local area network using the 802.11 series of protocols. In a WLAN, a basic service set (BSS) is a basic component of a WLAN. A BSS network is composed of station devices with certain associations 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 BSS (IBSS). Another more common scenario is that in a BSS network, there is only one central station with a dedicated BSS management function, which is called an access point device, and other stations in the BSS network that are not APs are called terminals, also called non-AP STAs. APs and non-AP STAs are collectively referred to as STAs. When describing STAs, there is no need to distinguish between APs and non-AP STAs. In the same BSS network, due to distance, transmission power, etc., a STA cannot detect other STAs that are farther away from it, and the two are each other's hidden nodes.

[0075] A multi-link access point device (AP MLD) and a multi-link station device (non-AP MLD) can establish multiple links across frequency bands, with independent power-saving capability information for each link. The non-AP MLD uses each link to indicate the power management mode of the non-AP STA attached to the non-AP MLD. Specifically, when the non-AP MLD intends to enter power saving (PS) mode on multiple or all links, it must perform frame exchange on each enabled link. This link-by-link frame exchange method for switching PS modes is inefficient and may cause the non-AP STA attached to the non-AP MLD to remain in sleep mode for an extended period of time.

[0076] The above-mentioned non-AP MLD power saving mode cannot meet the requirements of the next generation Wi-Fi technology - Ultra High Reliability (UHR) in terms of reducing latency and reducing device-level power consumption. For example, a non-AP STA sets the Power Management field to 1 to indicate that it is working in Power Saving Mode (PS Mode). After completing the current frame exchange, it enters PS Mode. When a non-AP STA is in the Doze state, it is awakened periodically to listen to beacon frames. When the AP has cached data to send to the non-AP STA, the non-AP STA switches to the Awake state and sends frames such as Power Saving Poll (PS-Poll) frames to inform the AP that it is in the Awake state. After receiving the PS-Poll and other frames, the AP sends its cached data to the non-AP STA. On the one hand, when a non-AP STA operates in PS Mode, the AP needs to buffer its downlink data until the non-AP STA wakes up before transmitting it, making it difficult to ensure the transmission of low-latency services. On the other hand, when a non-AP STA is in the Awake state, all its corresponding RF links are enabled. When the transmission demand is small, the Awake state may result in excessive energy consumption.

[0077] How to reduce device-level energy consumption while reducing transmission latency has become one of the research focuses in the Wi-Fi field. In some embodiments, a dynamic power saving mode is proposed. Specifically, a station (or access point) device can operate in a dynamic power saving mode. In this mode, the Wi-Fi device (i.e., station device or access point device) remains in a low power consumption state (e.g., low-capability communication mode, specifically, the parameter value of at least one communication parameter in the low power capability communication mode is less than the parameter value in the normal communication mode). If the peer device has data to transmit, a specific initial control frame can be sent to the device in the low power capability communication mode to initiate a frame exchange between the two. Taking the station device as an example, if the station device supports the dynamic power saving mode, the station device can send a dynamic power saving mode request frame to its associated access point device, and carry relevant parameter information for entering the dynamic power saving mode. After the access point device receives the request and is ready to serve the station device in the dynamic power saving mode (i.e., the access point device enters a ready state for communicating with the station device that has entered the dynamic power saving mode), it will send a response frame to the station device. When the site device operates in the dynamic power saving mode, the access point device initiates transmission with the site device by sending an initial control frame; after receiving the initial control frame, the site device switches from a lower power consumption state to a higher power consumption state (specifically, the parameter value of at least one communication parameter in the lower power consumption capability communication mode is less than the parameter value in the higher power consumption capability communication mode) to perform frame exchange with the site device that sent the initial control frame.

[0078] The relevant technology has not yet clarified the DPS mode negotiation process and parameter information between Wi-Fi devices, nor has the relevant signaling been standardized. In addition, most devices that support the UHR protocol are configured as MLD devices. How to achieve efficient negotiation and state transition of dynamic power saving mode between multi-link devices also requires standardized signaling and processes.

[0079] The present disclosure provides a communication method, communication device, and communication system to further standardize the signaling regarding the DPS mode negotiation process and parameter information between Wi-Fi devices, as well as the signaling and process for efficient negotiation and state switching of the dynamic power saving mode between multi-link devices.

[0080] Figure 2 FIG. 1 is an interactive diagram of a communication method according to an embodiment of the present disclosure. Figure 2 As shown, the above method includes:

[0081] In step 201, a non-AP MLD determines a first radio frame; the first radio frame is used to request: a non-AP STA associated station device corresponding to at least one link to enable or disable a dynamic power saving mode; the at least one link includes: a link among multiple links established between the non-AP MLD and a multi-link access point device AP MLD.

[0082] An embodiment of the present disclosure provides a communication method in which a non-AP MLD determines a first radio frame and sends the first radio frame to the AP MLD over a first link among multiple links established with the AP MLD. The first radio frame requests that a non-AP STA, an attached station device corresponding to at least one link, enable or disable a dynamic power saving mode. This method enables efficient negotiation of a dynamic power saving mode between multi-link devices over a single link among the multiple links established between the multi-link devices, thereby standardizing and improving the dynamic power saving operation process.

[0083] In some embodiments, the dynamic power saving mode (dynamic PS mode) may include: switching between a first capability communication mode and a second capability communication mode; wherein the first capability communication mode and the second capability communication mode include at least one identical communication parameter, and the parameter value of the communication parameter in the first capability communication mode is less than that in the second capability communication mode.

[0084] Optionally, switching between the first capability communication mode and the second capability communication mode is performed, i.e., switching from the first capability communication mode to the second capability communication mode, and switching from the second capability communication mode to the first capability communication mode. For example, in the dynamic power saving mode, when no frame exchange is performed, the communication mode is in the first capability communication mode, and in the dynamic power saving mode, when frame exchange is performed, the communication mode is in the second capability communication mode.

[0085] Optionally, the first capability communication mode may also be referred to as a first power mode, a first capability communication mode, a low energy communication mode, a low power consumption state, a low capability communication mode, a low power communication mode, a lower capability communication mode, a listening mode, or a low power communication stage, etc., and the embodiments of the present disclosure do not limit these names. The second capability communication mode may also be referred to as a high power mode, a second capability communication mode, a high capability communication mode, a high energy communication mode, a high power consumption state, a high power communication mode, a higher capability communication mode, or a high power communication stage, etc., and the embodiments of the present disclosure do not limit these names.

[0086] Optionally, in order to be compatible with the current PS (power saving) mode, the first capability communication mode may include the Doze State (doze state, also called sleep state) corresponding to the PS mode, and the second capability communication mode may include the Awake State (wake-up state) corresponding to the PS mode. The embodiments of the present disclosure do not make specific limitations on this.

[0087] Optionally, the parameter value of the communication parameter in the first capability communication mode is smaller than that in the second capability communication mode, which may mean that the communication capability of the communication device in the first capability communication mode is weaker than that in the second capability communication mode.

[0088] Optionally, during data communication by the first device, that is, when the first device turns off the dynamic power saving mode, the communication mode of the first device may include a third capability communication mode. Optionally, the third capability communication mode may include an Active Mode corresponding to the PS mode.

[0089] Optionally, the first capability communication mode and the third capability communication mode include at least one identical communication parameter, and a parameter value of the communication parameter in the first capability communication mode is weaker than that in the third capability communication mode.

[0090] Optionally, the third capability communication mode may include at least one of the same communication parameters as the second capability communication mode, and the parameter value of the communication parameter in the third capability communication mode may be greater than or equal to that in the second capability communication mode. In other words, the communication capability of the communication device in the first capability communication mode is weaker than the communication capability in the third capability communication mode, and the communication capability in the first capability communication mode is weaker than the communication capability in the second capability communication mode. However, the communication capability of the communication device in the third capability communication mode may be stronger than or equal to the communication capability in the second capability communication mode.

[0091] Optionally, the communication parameters corresponding to the first capability communication mode, the second capability communication mode, or the third capability communication mode may include, but are not limited to, channel bandwidth (ChannelBandWidth; BandWidth, referred to as BW), supported MCS mode, NSS (number of Spatial Stream, number of spatial streams), transmission rate, etc. The following is an example of the communication parameter values of the first device in the first capability communication mode and the third capability communication mode.

[0092] Optionally, in the first capability communication mode, the channel bandwidth supported by the device is 20 MHz (Mega Hertz) (i.e., BW = 20 MHz), the number of SSs is 1 (i.e., NSS = 1, single spatial stream), and the value of the MCS index is up to 5, that is, the value of the MCS index can be any value from 0 to 5, for example, the value of the MCS index is 5, etc. In the second capability communication mode, the channel bandwidth supported by the device can be greater than or equal to 20 MHz, for example, it can be any one or more of 40 MHz, 80 MHz, 160 MHz or 320 MHz, the number of SSs can be greater than or equal to 2, the MCS index can be greater than or equal to 5, etc. The specific parameter values can be determined according to the communication parameter values supported by the second device or according to the communication requirements of the second device and the first device.

[0093] Optionally, in a 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, modulation mode supported by each spatial stream, coding rate, BW, device transmission resource type [for example, resource unit RU, multiple resource unit (MRU), distributed resource unit (dRU), UEQM, etc.], whether the device supports BW punctured channel mode (punctured pattern) and at least one of the punctured channel density supported by the device.

[0094] For example, for each communication parameter, the device may determine whether it supports each specific parameter value. For example, for NSS, the maximum NSS supported by the device may be 4, 8, or 16. Taking modulation as an example, the modulation mode supported by a spatial stream supported by the device may be at least one of binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), 16-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 may be 1 / 2, 2 / 3, 3 / 4, or 5 / 6. Taking bandwidth as an example, the bandwidth supported by the device may be at least one of 20 MHz, 40 MHz, 80 MHz, 160 MHz, and 320 MHz. When the device supports the BW puncturing channel mode, the puncturing channel density supported by the device may be at least one of 20 MHz, 40 MHz, 80 MHz, 160 MHz, and 320 MHz.

[0095] In some embodiments, for a non-AP STA attached to a non-AP MLD, if the non-AP STA supports the dynamic power saving mode, the non-AP STA may be requested via a first radio frame whether to enable or disable the dynamic power saving mode.

[0096] In some embodiments, enabling the dynamic power saving mode may also be referred to as “turning on the dynamic power saving mode”.

[0097] In some embodiments, turning off the dynamic power saving mode may also be referred to as “disabling the dynamic power saving mode”.

[0098] In some embodiments, the subordinate non-AP STA corresponding to at least one link enables or disables the dynamic power saving mode, that is, the subordinate non-AP STA working under at least one link enables or disables the dynamic power saving mode.

[0099] In some embodiments, based on the first radio frame requesting the non-AP STA associated with at least one link to enable or disable the dynamic power saving mode, the first radio frame may further carry at least one of the following durations associated with each non-AP STA associated with the AP MLD:

[0100] (1) The off-state power saving mode and the time required to switch from the first capability communication mode to the second capability communication mode;

[0101] (2) The time required to enable the dynamic power saving mode and switch from the second capability communication mode to the first capability communication mode.

[0102] Optionally, the first radio frame may further include a time duration required for each subordinate non-AP STA of the AP MLD to switch from the first capability communication mode to the second capability communication mode in the dynamic power saving mode.

[0103] Step 202: The non-AP MLD sends the first radio frame to the AP MLD over a first link among multiple links established with the AP MLD. Correspondingly, the AP MLD receives the first radio frame sent by the non-AP MLD over the first link.

[0104] In some embodiments, there is no restriction on the number of links established between the non-AP MLD and the AP MLD, and on the operating frequency band of each link.

[0105] In some embodiments, it should be understood that the subordinate non-AP STA in at least one of the multiple links established between the non-AP MLD and the AP MLD is a non-AP STA subordinate to the non-AP MLD in the corresponding link.

[0106] In some embodiments, the first link may be any one of multiple links established between the non-AP MLD and the AP MLD. More specifically, the first link may be any one of the multiple links established between the non-AP MLD and the AP MLD, and corresponding to at least one link for normal communication between the attached non-AP STA and the STA.

[0107] See also Figure 3 In some embodiments, the communication method provided by the embodiments of the present disclosure may include:

[0108] Step 301: The non-AP MLD determines a third radio frame; wherein the third radio frame carries delay information for a non-AP STA affiliated with the non-AP MLD to switch between a first capability communication mode and a second capability communication mode;

[0109] The state includes a first capability communication mode or a second capability communication mode; and a parameter value of at least one communication parameter in the first capability communication mode is smaller than a parameter value in the second capability communication mode.

[0110] Optionally, the delay information for a non-AP STA of the non-AP MLD to switch between the first capability communication mode and the second capability communication mode may specifically include at least one of the following:

[0111] (1) The duration required for a non-AP STA to enable dynamic power saving mode and switch from the second capability communication mode to the first capability communication mode;

[0112] (2) The duration required for a non-AP STA to switch from the first capability communication mode to the second capability communication mode in the power saving mode of the non-AP STA shutdown state.

[0113] Optionally, when the delay information corresponding to each subordinate non-AP STA of the non-AP MLD is the same, in the third wireless frame, the delay information corresponding to each subordinate non-AP STA can be identified separately, or only one delay information can be identified. That is, when only one delay information is included in the third wireless frame, it is indicated that the delay information corresponding to all non-AP STAs subordinate to the non-APMLD is the same.

[0114] Optionally, when the delay information corresponding to at least two non-AP STAs attached to the non-AP MLD is different, the delay information corresponding to each non-AP STA may be identified separately in the third radio frame.

[0115] In some embodiments, the delay information includes at least one of the following:

[0116] A first delay, indicating the time required for the attached non-AP STA operating on the first link to start the dynamic power saving mode and switch from the second capability communication mode to the first capability communication mode;

[0117] A second delay, indicating the duration required for the attached non-AP STA operating in the first link in the shutdown power saving mode to switch from the first capability communication mode to the second capability communication mode;

[0118] at least one third delay, where the third delay indicates: a time duration required for a subordinate non-AP STA of the non-AP MLD to enable dynamic power saving mode and switch from the second capability communication mode to the first capability communication mode;

[0119] At least one fourth delay, where the fourth delay indicates: a time length required for a subordinate non-AP STA of the non-AP MLD to start the dynamic power saving mode and switch from the first capability communication mode to the second capability communication mode.

[0120] Optionally, for an attached non-AP STA, the first duration and second duration corresponding to the non-AP STA may be the same or different, and the embodiments of the present disclosure do not impose any restrictions on this. The first duration is the duration required for the non-AP STA to turn on the dynamic power saving mode and switch from the second capability communication mode to the first capability communication mode; the second duration is the duration required for the non-AP STA to turn off the power saving mode and switch from the first capability communication mode to the second capability communication mode.

[0121] Optionally, if the first and second durations corresponding to an attached non-AP STA are the same, the latency information corresponding to the non-AP STA may include only one item. For example, for an attached non-AP STA operating on the first link, the latency information corresponding to the non-AP STA may include only the first or second latency. For example, for an attached non-AP STA operating on any link, the latency information corresponding to the non-AP STA may include only the third or fourth latency corresponding to the non-AP STA.

[0122] That is, the first delay and the second delay may be the same or different. For a certain attached non-AP STA, the third delay corresponding to the non-AP STA and the fourth delay corresponding to the non-AP STA may be the same or different.

[0123] In some embodiments, when the third radio frame includes only the first delay and the second delay, each subordinate non-AP STA of the non-AP MLD turns on the dynamic power saving mode, and the duration required for switching from the second capability communication mode to the first capability communication mode is the first delay; each subordinate non-AP STA of the non-AP MLD turns off the dynamic power saving mode, and the duration required for switching from the first capability communication mode to the second capability communication mode is the second delay;

[0124] When the third radio frame includes the at least one third delay and the at least one fourth delay, each subordinate non-AP STA of the non-AP MLD turns on the dynamic power saving mode, and the time required to switch from the second capability communication mode to the first capability communication mode is the corresponding third delay; each subordinate non-AP STA of the non-AP MLD turns off the dynamic power saving mode, and the time required to switch from the first capability communication mode to the second capability communication mode is the corresponding fourth delay.

[0125] Optionally, in the case where the third wireless frame only includes the first delay and the second delay, that is, the delay information corresponding to all non-AP STAs attached to the non-AP MLD is the same, each non-AP STA turns on the dynamic power saving mode, and the time required to switch from the second capability communication mode to the first capability communication mode is the first delay, and each non-AP STA turns off the dynamic power saving mode, and the time required to switch from the first capability communication mode to the second capability communication mode is the second delay.

[0126] In the case where the third wireless frame includes only at least one third delay and at least one fourth delay, that is, the delay information corresponding to at least two non-AP STAs attached to the non-AP MLD is different, for a non-AP STA attached to the non-AP MLD, the third delay corresponding to the non-AP STA can be used to identify: the non-AP STA turns on the dynamic power saving mode, and the time required to switch from the second capability communication mode to the first capability communication mode; the fourth delay corresponding to the non-AP STA can be used to identify: the non-AP STA turns off the dynamic power saving mode, and the time required to switch from the first capability communication mode to the second capability communication mode is the corresponding fourth delay.

[0127] Step 302: The non-AP MLD sends the third radio frame to the AP MLD. Correspondingly, the AP MLD receives the third radio frame sent by the non-AP MLD.

[0128] Optionally, the non-AP MLD may send the third radio frame to the AP MLD over the first link; or may send the third radio frame to the AP MLD over other links. For example, the non-AP MLD may send the third radio frame to the AP MLD over the second link among multiple links established between the non-AP MLD and the AP MLD, which corresponds to normal communication between the non-AP STA and the STA.

[0129] In step 303, the non-AP MLD determines a first radio frame; wherein the first radio frame is used to request: a non-AP STA affiliated station device corresponding to at least one link to enable or disable a dynamic power saving mode; the at least one link includes: a link among multiple links established by the non-AP MLD and a multi-link access point device AP MLD.

[0130] In some embodiments, the dynamic power saving mode may include: switching between a first capability communication mode and a second capability communication mode; wherein the first capability communication mode and the second capability communication mode include at least one identical communication parameter, and the parameter value of the communication parameter in the first capability communication mode is smaller than that in the second capability communication mode. Specific parameter information for the first capability communication mode and the second capability communication mode can be found in the above content and is not further described here.

[0131] In some embodiments, for a non-AP STA attached to a non-AP MLD, if the non-AP STA supports the dynamic power saving mode, the non-AP STA may be requested via a first radio frame whether to enable or disable the dynamic power saving mode.

[0132] In some embodiments, there is no restriction on the number of links established between the non-AP MLD and the AP MLD, and on the operating frequency band of each link.

[0133] In some embodiments, the non-AP STA, an affiliated station device corresponding to at least one link, enables or disables a dynamic power saving mode, that is, the non-AP STA working under at least one link enables or disables the dynamic power saving mode.

[0134] In some embodiments, it should be understood that the subordinate non-AP STA in at least one of the multiple links established between the non-AP MLD and the AP MLD is a non-AP STA subordinate to the non-AP MLD in the corresponding link.

[0135] In some embodiments, based on the first radio frame requesting the non-AP STA associated with at least one link to enable or disable the dynamic power saving mode, the first radio frame may further carry at least one of the following durations associated with each non-AP STA associated with the AP MLD:

[0136] (1) The off-state power saving mode and the time required to switch from the first capability communication mode to the second capability communication mode;

[0137] (2) The time required to enable the dynamic power saving mode and switch from the second capability communication mode to the first capability communication mode.

[0138] Optionally, the first radio frame may further include a time duration required for each subordinate non-AP STA of the AP MLD to switch from the first capability communication mode to the second capability communication mode in the dynamic power saving mode.

[0139] Optionally, the first radio frame may also carry the content carried in the third radio frame. In this way, step 301 and step 302 may be omitted.

[0140] Optionally, Figure 3 The description is given by taking the example that the combined steps of step 303 and step 304 are implemented independently, and the combined steps of step 301 and step 302 are implemented independently, that is, the content carried in the third wireless frame is not carried in the first wireless frame, and the combined steps of step 303 and step 304 are performed after the combined steps of step 301 and step 302.

[0141] Step 304: The non-AP MLD sends the first radio frame to the AP MLD over a first link among multiple links established with the AP MLD. Correspondingly, the AP MLD receives the first radio frame sent by the non-AP MLD over the first link.

[0142] In some embodiments, the first link may be any one of multiple links established between the non-AP MLD and the AP MLD. More specifically, the first link may be any one of the multiple links established between the non-AP MLD and the AP MLD, and corresponding to at least one link for normal communication between the attached non-AP STA and the STA.

[0143] In the above embodiment, the non-AP MLD determines a first radio frame and sends the first radio frame to the AP MLD over a first link among the multiple links established with the AP MLD. The first radio frame requests that the attached non-AP STA operating over at least one of the multiple links established with the AP MLD enable or disable dynamic power saving mode. In this way, efficient negotiation of dynamic power saving mode between multi-link devices can be achieved over a single link among the multiple links established between the multi-link devices, standardizing and improving the dynamic power saving operation process.

[0144] In some embodiments, the first radio frame may include at least one of the following:

[0145] A first field, where the first field identifies that the first radio frame is used to request enabling a dynamic power saving mode or to request disabling a dynamic power saving mode;

[0146] The second field indicates: at least one affiliated non-AP STA that requests to enable or disable the dynamic power saving mode.

[0147] Optionally, the first field is a mode indication field used to identify whether the non-AP MLD enables or disables the dynamic power saving mode. For example, the first field may include a dynamic power saving mode enable / disable (DPS Mode Enable / Disable) field.

[0148] Optionally, the DPS Mode Enable / Disable field may occupy at least one bit, and the specific content indicated, that is, enable DPS Mode or disable DPS Mode, may be identified by a parameter value of the bit.

[0149] Optionally, taking the DPS Mode Enable / Disable field occupying one bit as an example, when the DPS ModeEnable / Disable field is set to "1", it indicates that the non-AP MLD enables dynamic power saving mode (i.e., enable DPS Mode); when the DPS Mode Enable / Disable field is set to "0", it indicates that the non-APMLD turns off dynamic power saving mode (i.e., disable DPS Mode).

[0150] Optionally, taking the DPS Mode Enable / Disable field occupying two bits as an example, when the DPS ModeEnable / Disable field is set to "01", it indicates that non-AP MLD enables dynamic power saving mode (i.e., enable DPS Mode); when the DPS Mode Enable / Disable field is set to "00", it indicates that non-AP MLD disables dynamic power saving mode (i.e., disable DPS Mode).

[0151] Optionally, the second field may specifically include identification information of the affiliated non-AP STA that needs to enable or disable the dynamic power saving mode (i.e., requesting to enable or disable the dynamic power saving mode), for example, it may be at least one of the device information of the non-AP STA, the link information of the link where the non-AP STA is located, the medium access control (MAC) address information of the non-AP STA, etc., which is not limited in this embodiment of the present disclosure.

[0152] Optionally, the second field may include a dynamic power saving mode bitmap field (DPS Bitmap).

[0153] Optionally, in some embodiments, in the first wireless frame, the first field and the second field may be independent fields, or independent subfields in a certain field, which is not limited here.

[0154] For example, taking the first field and the second field as independent fields as an example, the first wireless frame may include field A and field B, field A is the first field, and field B is the second field; taking the first field and the second field as independent subfields in a certain field as an example, the first wireless frame may include field C, and field C may include subfield c1, subfield c2 and subfield c3, where subfield c1 is the first field and subfield c2 is the second field.

[0155] Optionally, in some embodiments, when the first radio frame itself is a radio frame requesting an instruction to enable or disable the dynamic power saving mode, the first radio frame may include only the second field, used to indicate: among the non-AP STAs attached to the non-AP MLD, the non-AP STAs for which the dynamic power saving mode needs to be enabled or disabled; or, the second radio frame may include only the first field, used to indicate that all non-AP STAs attached to the non-AP MLD need to enable or disable the dynamic power saving mode.

[0156] Optionally, in some embodiments, when the first wireless frame includes both the first field and the second field, the first field can be used to identify whether the non-AP MLD enables or disables the dynamic power saving mode; and the second field can be used to identify which non-AP STAs attached to the non-AP MLD need to enable or disable the dynamic power saving mode.

[0157] Optionally, in some embodiments, the same subfield may exist in the first field and the second field. For example, the same subfield in the first field and the second field may indicate whether the dynamic power saving mode is enabled or disabled, and different subfields in the first field and the second field may indicate: among the non-AP STAs attached to the non-AP MLD, the non-AP STAs that need to enable or disable the dynamic power saving mode.

[0158] As an example, in the first wireless frame, field D may be included, and at least one bit in the field may be used as the first field to indicate whether the dynamic power saving mode is enabled or disabled; the remaining bits in the field may be used as the second field to indicate: among the non-AP STAs attached to the non-AP MLD, the non-APSTAs that need to enable or disable the dynamic power saving mode.

[0159] In some embodiments, the first radio frame may further include:

[0160] The third field identifies whether the first wireless frame contains the second field.

[0161] Optionally, the third field may include a dynamic power saving mode bitmap present (DPS Bitmap Present) field / identifier.

[0162] In some embodiments, the third field may include a DPS Bitmap Present identifier;

[0163] The DPS Bitmap Present identifier is set to a first parameter value, and the first radio frame includes the second field;

[0164] The DPS Bitmap Present identifier is set to a second parameter value, and the first radio frame does not include the second field.

[0165] Optionally, the DPS Bitmap Present identifier may occupy at least one bit.

[0166] Optionally, taking the DPS Bitmap Present identifier occupying one bit as an example, the first parameter value may include "1" and the second parameter value may include "0", that is, when the DPS Bitmap Present identifier is set to "1", it indicates that the first wireless frame includes the second field; when the DPS Bitmap Present identifier is set to "0", it indicates that the first wireless frame does not include the second field.

[0167] Optionally, taking the DPS Bitmap Present identifier occupying two bits as an example, the first parameter value may include "01" and the second parameter value may include "00", that is, when the DPS Bitmap Present identifier is set to "01", it indicates that the first wireless frame includes the second field; when the DPS Bitmap Present identifier is set to "00", it indicates that the first wireless frame does not include the second field.

[0168] In some embodiments, the first radio frame does not include the second field, and the first radio frame requests: an affiliated non-AP STA operating in the first link to perform an operation identified by the first field;

[0169] The first radio frame includes the second field, and the first radio frame requests: the subordinate non-AP STA indicated by the second field to perform the operation identified by the first field.

[0170] Optionally, the first radio frame does not include the second field, which can also be understood as the first radio frame including the first field but not the second field. Accordingly, the third field DPS Bitmap Present identifier is set to the second parameter value.

[0171] Optionally, when the first radio frame does not include the second field, the non-AP MLD may request, through the first field in the first radio frame, that the affiliated non-AP STA operating under the first link perform the operation identified by the first field, that is, the first radio frame requests that the affiliated non-AP STA operating under the first link perform the operation identified by the first field.

[0172] Optionally, in the case where the first radio frame includes the second field, the non-AP MLD may request the non-AP MLD to enable or disable the dynamic power saving mode through the first field in the first radio frame, and at the same time, request at least one non-AP STA attached to the non-AP MLD to perform the operation identified by the first field through the second field in the first radio frame. That is, the first radio frame requests: the attached non-AP STA indicated by the second field to perform the operation identified by the first field.

[0173] Optionally, in some embodiments, assuming that the non-AP STA indicated by the first field needs to disable DPS mode, when the first wireless frame includes the second field, the first wireless frame identifier: the non-AP STA disable DPS mode indicated by the second field; when the first wireless frame does not include the second field, the first wireless frame identifier: the non-AP STA disable DPS mode working under the first link.

[0174] Optionally, in some embodiments, assuming that the non-AP STA indicated by the first field needs to enable DPS mode, when the first radio frame includes the second field, the first radio frame identifier: the non-AP STA enable DPS mode indicated by the second field; when the first radio frame does not include the second field, the first radio frame identifier: the non-AP STA enable DPS mode working under the first link.

[0175] In some embodiments, the second field includes a DPS Mode bitmap field; the DPS Mode bitmap field includes at least one bit; each bit corresponds to a working link of an attached non-AP STA attached to the non-AP MLD;

[0176] The bit is set to a third parameter value, indicating that the attached non-AP STA operating on the link corresponding to the bit performs the operation indicated by the first field;

[0177] The bit is set to a fourth parameter value, indicating that the subordinate non-AP STA working under the link corresponding to the bit does not perform the operation identified by the first field.

[0178] In some embodiments, the second field may include a first subfield including the above-mentioned DPSMode bitmap field.

[0179] Optionally, the number of bits in the DPS Mode bitmap field can be determined based on the number of links established between the non-AP MLD and AP MLD. For example, if there are 16 links established between the non-AP MLD and AP MLD, namely Link 0 to Link 15, the DPS Mode bitmap field can occupy 16 bits, with each bit corresponding to a link established between the non-AP MLD and AP MLD.

[0180] It can be understood that a non-AP STA attached to a non-AP MLD and an AP attached to an AP MLD communicate over a link established between the non-AP MLD and the AP MLD. In other words, they operate over a link established between the non-AP MLD and the AP MLD. Accordingly, the non-AP STA is a non-AP STA operating over this link, and the AP is an AP operating over this link.

[0181] Optionally, the third parameter value may be "1" and the fourth parameter value may be "0", that is, for a bit in the DPS Modebitmap field, when the bit is set to "1", it indicates that the affiliated non-AP STA working under the link corresponding to the bit performs the operation identified by the first field, that is, the affiliated non-AP STA needs to enable or disable the dynamic power saving mode; when the bit is set to "0", it indicates that the affiliated non-AP STA working under the link corresponding to the bit does not perform the operation identified by the first field, that is, the affiliated non-AP STA does not enable or disable the dynamic power saving mode.

[0182] Optionally, referring to the above, the formats of the first field, the second field and the third field in the first wireless frame can be shown in Table 1.

[0183] Table 1:

[0184]

[0185] In some embodiments, when the first field indicates that the dynamic power saving mode is turned off,

[0186] In the second field, a bit corresponding to the link on which the subordinate non-AP STA requesting to disable the dynamic power saving mode operates is set to a third parameter value;

[0187] In the second field, bits corresponding to enabled links in the plurality of links for which the dynamic power saving mode is not enabled are set to a fourth parameter value;

[0188] In the second field, bits corresponding to disabled links among the plurality of links are set to a fourth parameter value.

[0189] Optionally, among the multiple links established between the non-AP MLD and the AP MLD, some or all of the links may be in working state. That is, among the multiple links, all or some of the links may be enabled. The enabled links are links in working state, and the disabled links are links in non-working state.

[0190] Optionally, for an enabled link among the multiple links, only the subordinate non-AP STAs under the link need to enable or disable the dynamic power saving mode. To this end, when the first field indicates that the dynamic power saving mode is disabled, in the second field, the bit corresponding to the link on which the subordinate non-AP STA requesting to disable the dynamic power saving mode operates is set to a third parameter value; and in the second field, the bit corresponding to the enabled link for which the dynamic power saving mode was not previously enabled (before determining the first radio frame) is set to a fourth parameter value.

[0191] Optionally, for a disabled link among the multiple links, the affiliated non-AP STAs under the link do not need to enable or disable the dynamic power saving mode. Accordingly, when the first field indicates that the dynamic power saving mode is disabled, in the second field, the bit corresponding to the previously disabled link (before determining the first radio frame) is set to a fourth parameter value.

[0192] In some embodiments, when the first field indicates that the dynamic power saving mode is enabled,

[0193] In the second field, the bit corresponding to the link on which the subordinate non-AP STA requesting to enable the dynamic power saving mode operates is set to a third parameter value;

[0194] In the second field, the bit corresponding to the link for which the corresponding attached non-AP STA does not need to enable the dynamic power saving mode and has been enabled is set to the fourth parameter value;

[0195] In the second field, bits corresponding to disabled links are set to a fourth parameter value.

[0196] As previously mentioned, an enabled link among the multiple links is a link in an operational state, and a disabled link is a link in an inoperative state. Optionally, only the non-AP STAs attached to an enabled link among the multiple links need to enable or disable dynamic power saving mode. For a disabled link among the multiple links, the non-AP STAs attached to the disabled link do not need to enable or disable dynamic power saving mode.

[0197] In this regard, when the first field indicates that the dynamic power saving mode is enabled, in the second field, the bit corresponding to the link on which the affiliated non-AP STA requesting the dynamic power saving mode is operating is set to the third parameter value; in the second field, the bit corresponding to the link for which the corresponding affiliated non-AP STA does not need to enable the dynamic power saving mode and has been enabled is set to the fourth parameter value; and in the second field, the bit corresponding to the disabled link is set to the fourth parameter value.

[0198] Optionally, in the embodiment of the present disclosure, the combination of step 303 and step 304 may be performed after the combination of step 301 and step 302, or the two combined steps may be performed simultaneously. That is, the step of the non-AP MLD sending the third radio frame to the AP MLD may be performed before the step of the non-AP MLD sending the first radio frame to the AP MLD, or the step of the non-AP MLD sending the third radio frame to the AP MLD may be performed simultaneously with the step of the non-AP MLD sending the first radio frame to the AP MLD. Figure 3 The description is given by taking the example that the combination of step 303 and step 304 is performed after the combination of step 301 and step 302.

[0199] Step 305: The AP MLD determines a second radio frame; wherein the second radio frame indicates that the AP MLD has entered a preparation state for communicating with the non-AP MLD based on the request information in the first radio frame.

[0200] Optionally, the AP MLD has entered a ready state for communicating with the non-AP MLD based on the request information of the first radio frame, that is, the AP attached to the AP MLD and working under the above at least one link has entered a ready state for communicating with the non-APSTA under the link.

[0201] Specifically, when the first wireless frame requests the affiliated non-AP STA under a certain link to enable the dynamic power saving mode, the AP under the link enters a ready state for communicating with the non-AP STA that has enabled the dynamic power saving mode; when the first wireless frame requests the non-AP STA under a certain link to disable the dynamic power saving mode, the AP under the link enters a ready state for communicating with the non-AP STA that has disabled the dynamic power saving mode (in this case, the AP can interrupt the communication process with the non-AP STA).

[0202] Optionally, the AP MLD enters a corresponding preparation state, ie, the subordinate AP of the AP MLD has adjusted its communication parameters, and the adjusted communication parameters are adaptable to the communication process with the subordinate non-AP STA with dynamic power saving mode enabled or disabled.

[0203] Optionally, the second wireless frame may also carry at least one of the above-mentioned first field, second field and third field, and the content of the first field is the same as the content of the first field in the first wireless frame, the second field is the same as the content of the second field in the first wireless frame, and the third field is the same as the content of the third field in the first wireless frame.

[0204] Step 306: The AP MLD sends a second radio frame to the non-AP MLD. Correspondingly, the non-AP MLD receives the second radio frame sent by the AP MLD.

[0205] Optionally, the AP MLD may send the second radio frame to the non-AP MLD through the first link, or may send the second radio frame to the non-AP MLD through other links. For example, the AP MLD sends the second radio frame to the non-AP MLD in the second link among the multiple links established between the non-AP MLD and the corresponding attached non-AP STA and the STA in which the STA communicates normally.

[0206] Step 307: The non-AP MLD enables or disables the dynamic power saving mode according to the state of the non-AP MLD when sending the first radio frame.

[0207] Optionally, the state of the non-AP MLD when sending the first radio frame, that is, the working state of the non-AP STA attached to the non-AP MLD when the non-AP MLD sends the first radio frame, may include but is not limited to the above-mentioned first capability communication mode, second capability communication mode or third capability communication mode.

[0208] In some embodiments, when the first radio frame does not include the second field, the non-AP MLD enables or disables the dynamic power saving mode according to its state when sending the first radio frame, including at least one of the following:

[0209] When the first field of the first radio frame indicates that the dynamic power saving mode is enabled, the first affiliated non-AP STA operating on the first link switches to the first capability communication mode within a first delay and enables the dynamic power saving mode;

[0210] In a case where the first field indicates that the dynamic power saving mode is disabled, if the first affiliated non-AP STA is in a first capability communication mode when sending the first radio frame, the first affiliated non-AP STA switches to a second capability communication mode within a second delay and disables the dynamic power saving mode;

[0211] In a case where the first field indicates that the dynamic power saving mode is disabled, if the first affiliated non-AP STA is in the second capability communication mode when sending the first wireless frame, the first affiliated non-AP STA disables the dynamic power saving mode.

[0212] Optionally, the non-AP MLD enables or disables the dynamic power saving mode according to its state when sending the first radio frame and information indicated by the first field in the first radio frame.

[0213] Optionally, when the non-AP MLD enables or disables the dynamic power saving mode, the dynamic power saving mode may be enabled or disabled based on the delay information related to enabling or disabling the dynamic power saving mode indicated in the third radio frame.

[0214] Optionally, when the first radio frame does not include the second field, only the working state of the first affiliated non-AP STA working on the first link can be adjusted, that is, the dynamic power saving mode can be enabled or disabled according to the information indicated by the first field in the first radio frame.

[0215] Optionally, when the first field of the first radio frame indicates that the dynamic power saving mode is enabled, the first affiliated non-AP STA operating in the first link switches to the first capability communication mode within the first delay to enable the dynamic power saving mode.

[0216] Optionally, in the case where the first field indicates that the dynamic power saving mode is turned off, if the first affiliated non-AP STA is in the first capability communication mode when sending the first wireless frame, the first affiliated non-AP STA switches to the second capability communication mode within the second delay and turns off the dynamic power saving mode; if the first affiliated non-AP STA is in the second capability communication mode when sending the first wireless frame, the first affiliated non-AP STA turns off the dynamic power saving mode.

[0217] In some embodiments, when the first radio frame includes the second field, the non-AP MLD enables or disables the dynamic power saving mode according to its state when sending the first radio frame, including at least one of the following:

[0218] When the first field of the first radio frame indicates that the dynamic power saving mode is enabled, the second affiliated non-AP STA operating in the link corresponding to the bit set to the third parameter value switches to the first capability communication mode within a third delay to enable the dynamic power saving mode;

[0219] In a case where the first field indicates that the dynamic power saving mode is disabled, if the second affiliated non-AP STA is in the first capability communication mode when the non-AP MLD sends the first radio frame, the second affiliated non-AP STA switches to the second capability communication mode within a fourth delay and disables the dynamic power saving mode;

[0220] In the case where the first field indicates that the dynamic power saving mode is disabled, if the second affiliated non-AP STA is in the second capability communication mode when the non-AP MLD sends the first radio frame, the second affiliated non-AP STA disables the dynamic power saving mode.

[0221] Optionally, when the first radio frame includes the second field, it may be necessary to adjust the working state of at least one non-AP STA attached to the non-AP MLD, that is, enable or disable the dynamic power saving mode according to the information indicated by the first field in the first radio frame.

[0222] Optionally, as described above, the delay information corresponding to at least two non-AP STAs attached to the non-AP MLD may be different. Therefore, when the first radio frame includes the second field, the second attached non-AP STA operating in the link corresponding to the bit set to the third parameter value needs to enable or disable the dynamic power saving mode based on the state of the non-AP STA when the non-AP MLD sends the first radio frame, the delay information corresponding to the non-AP STA in the third radio frame, and the information indicated by the first field in the first radio frame.

[0223] That is, when the first field of the first radio frame indicates that the dynamic power saving mode is enabled, the second subordinate non-AP STA operating in the link corresponding to the bit set to the third parameter value switches to the first capability communication mode within the third delay and enables the dynamic power saving mode. When the first field indicates that the dynamic power saving mode is disabled, if the second subordinate non-AP STA is in the first capability communication mode when the non-AP MLD sends the first radio frame, the second subordinate non-AP STA switches to the second capability communication mode within the fourth delay and disables the dynamic power saving mode; if the second subordinate non-AP STA is in the second capability communication mode when the non-AP MLD sends the first radio frame, the second subordinate non-AP STA disables the dynamic power saving mode.

[0224] Optionally, as described above, the delay information corresponding to at least two non-AP STAs attached to the non-AP MLD may be the same. Therefore, when the first radio frame includes the second field and the third radio frame includes only the first delay and the second delay, the second attached non-AP STA operating in the link corresponding to the bit set to the third parameter value needs to enable or disable the dynamic power saving mode based on the state of the non-AP STA when the non-AP MLD sends the first radio frame, the delay information in the third radio frame corresponding to the information indicated by the first field in the first radio frame, and the information indicated by the first field in the first radio frame.

[0225] That is, when the first field of the first radio frame indicates that the dynamic power saving mode is enabled, the second subordinate non-AP STA operating in the link corresponding to the bit set to the third parameter value switches to the first capability communication mode within the first delay and enables the dynamic power saving mode. When the first field indicates that the dynamic power saving mode is disabled, if the second subordinate non-AP STA is in the first capability communication mode when the non-AP MLD sends the first radio frame, the second subordinate non-AP STA switches to the second capability communication mode within the second delay and disables the dynamic power saving mode; if the second subordinate non-AP STA is in the second capability communication mode when the non-AP MLD sends the first radio frame, the second subordinate non-AP STA disables the dynamic power saving mode.

[0244] The bit is set to a fourth parameter value, indicating that the subordinate non-AP STA working under the link corresponding to the bit does not perform the operation identified by the first field.

[0245] In some embodiments, when the first field indicates that the dynamic power saving mode is turned off,

[0253] Step A5: The AP MLD determines a second radio frame; wherein the second radio frame indicates that the AP MLD has entered a preparation state for communicating with the non-AP MLD based on the request information in the first radio frame.

[0254] In step A6, the AP MLD sends a second radio frame to the non-AP MLD. Correspondingly, the non-AP MLD receives the second radio frame sent by the AP MLD.

[0255] Step A7: The non-AP MLD enables or disables the dynamic power saving mode according to the state of the non-AP MLD when sending the first radio frame.

[0256] In some embodiments, when the first radio frame does not include the second field, the non-AP MLD enables or disables the dynamic power saving mode according to its state when sending the first radio frame, including at least one of the following:

[0338] A second delay, indicating the duration required for the attached non-AP STA operating in the first link in the shutdown power saving mode to switch from the first capability communication mode to the second capability communication mode;

[0339] at least one third delay, where the third delay indicates: a time duration required for a subordinate non-AP STA of the non-AP MLD to enable dynamic power saving mode and switch from the second capability communication mode to the first capability communication mode;

[0340] At least one fourth delay, where the fourth delay indicates: a time length required for a subordinate non-AP STA of the non-AP MLD to start the dynamic power saving mode and switch from the first capability communication mode to the second capability communication mode.

[0341] In some embodiments, when the third radio frame includes only the first delay and the second delay, each subordinate non-AP STA of the non-AP MLD turns on the dynamic power saving mode, and the duration required for switching from the second capability communication mode to the first capability communication mode is the first delay; each subordinate non-AP STA of the non-AP MLD turns off the dynamic power saving mode, and the duration required for switching from the first capability communication mode to the second capability communication mode is the second delay;

[0342] When the third radio frame includes the at least one third delay and the at least one fourth delay, each subordinate non-AP STA of the non-AP MLD turns on the dynamic power saving mode, and the time required to switch from the second capability communication mode to the first capability communication mode is the corresponding third delay; each subordinate non-AP STA of the non-AP MLD turns off the dynamic power saving mode, and the time required to switch from the first capability communication mode to the second capability communication mode is the corresponding fourth delay.

[0343] In step D2, the non-AP MLD sends the third radio frame to the AP MLD. Correspondingly, the AP MLD receives the third radio frame sent by the non-AP MLD.

[0344] In step D3, the non-AP MLD determines a first radio frame; wherein the first radio frame is used to request: a non-AP STA, an affiliated station device corresponding to at least one link, to enable or disable a dynamic power saving mode; the at least one link includes: a link among multiple links established between the non-AP MLD and a multi-link access point device AP MLD.

[0345] In step D4, the non-AP MLD sends the first radio frame to the AP MLD over a first link among the multiple links established with the AP MLD. Correspondingly, the AP MLD receives the first radio frame sent by the non-AP MLD over the first link.

[0346] In some embodiments, the first radio frame may include:

[0347] The second field indicates: at least one affiliated non-AP STA that requests to enable or disable the dynamic power saving mode.

[0348] In some embodiments, the first wireless frame may be used by default to request enabling or disabling the dynamic power saving mode. Accordingly, the second field identifies: the first wireless frame is used to request: at least one affiliated non-AP STA for the default operation of the first wireless frame (enabling or disabling the dynamic power saving mode).

[0349] In some embodiments, the first radio frame includes the second field, and the first radio frame requests that the subordinate non-AP STA indicated by the second field perform the operation identified by the first field.

[0350] In some embodiments, the second field includes a DPS Mode bitmap field; the DPS Mode bitmap field includes at least one bit; each bit corresponds to a working link of an attached non-AP STA attached to the non-AP MLD;

[0351] The bit is set to a third parameter value, indicating that the attached non-AP STA operating under the link corresponding to the bit performs the default operation of the first radio frame;

[0352] The bit is set to a fourth parameter value, indicating that the subordinate non-AP STA working in the link corresponding to the bit does not perform the default operation of the first radio frame.

[0353] In some embodiments, when the default operation of the first radio frame is to turn off the dynamic power saving mode,

[0354] In the second field, a bit corresponding to the link on which the subordinate non-AP STA requesting to disable the dynamic power saving mode operates is set to a third parameter value;

[0355] In the second field, bits corresponding to enabled links in the plurality of links for which the dynamic power saving mode is not enabled are set to a fourth parameter value;

[0356] In the second field, bits corresponding to disabled links among the plurality of links are set to a fourth parameter value.

[0357] In some embodiments, when the default operation of the first radio frame is to enable the dynamic power saving mode,

[0358] In the second field, the bit corresponding to the link on which the subordinate non-AP STA requesting to enable the dynamic power saving mode operates is set to a third parameter value;

[0359] In the second field, bits corresponding to links in the plurality of links for which the subordinate non-AP STA does not need to enable the dynamic power saving mode and the dynamic power saving mode has been enabled are set to a fourth parameter value;

[0360] In the second field, bits corresponding to disabled links among the plurality of links are set to a fourth parameter value.

[0361] Step D5: The AP MLD determines a second radio frame; wherein the second radio frame indicates that the AP MLD has entered a preparation state for communicating with the non-AP MLD based on the request information in the first radio frame.

[0362] In step D6, the AP MLD sends a second radio frame to the non-AP MLD. Correspondingly, the non-AP MLD receives the second radio frame sent by the AP MLD.

[0363] Step D7: The non-AP MLD enables or disables the dynamic power saving mode according to the state of the non-AP MLD when sending the first radio frame.

[0364] In some embodiments, the non-AP MLD enables or disables the dynamic power saving mode according to its state when sending the first radio frame, including at least one of the following:

[0365] When the first field of the first radio frame indicates that the dynamic power saving mode is enabled, the second affiliated non-AP STA operating in the link corresponding to the bit set to the third parameter value switches to the first capability communication mode within a third delay to enable the dynamic power saving mode;

[0366] In a case where the first field indicates that the dynamic power saving mode is disabled, if the second affiliated non-AP STA is in the first capability communication mode when the non-AP MLD sends the first radio frame, the second affiliated non-AP STA switches to the second capability communication mode within a fourth delay and disables the dynamic power saving mode;

[0367] In the case where the first field indicates that the dynamic power saving mode is disabled, if the second affiliated non-AP STA is in the second capability communication mode when the non-AP MLD sends the first radio frame, the second affiliated non-AP STA disables the dynamic power saving mode.

[0368] In some embodiments, the disclosed embodiments provide a method and process for dynamic power saving mode for multi-link devices. This method addresses at least one of the following issues: the lack of clear negotiation process and parameter information for DPS mode between Wi-Fi devices, the lack of standardized signaling, and the need for standardized signaling and processes to achieve efficient negotiation and state switching of dynamic power saving mode for multi-link devices, given that most devices supporting the UHR protocol are MLD devices.

[0369] In some embodiments, a non-AP MLD can request, via a single link, that one or more subordinate non-AP STAs disable or enable dynamic power saving mode from its associated AP MLD device. Upon receiving the request, the AP MLD responds. After the non-AP MLD receives the response, each subordinate non-AP STA switches to a corresponding capability communication mode within a corresponding delay time, based on the capability communication mode in which the non-AP MLD sent the request. This method effectively improves the efficiency of dynamic power saving mode negotiation between multi-link devices, enables efficient switching of capability modes for non-AP MLD devices, and standardizes and improves the dynamic power saving operation process.

[0370] Specifically, the above method may include the following steps:

[0371] 1. The Non-AP MLD sends a first radio frame to its associated AP MLD via a first link, requesting the associated non-AP STAs corresponding to one or more links to exit (disable) dynamic power saving mode (DPS Mode). The first radio frame includes at least one of the following:

[0372] (1) The first field identifies the enable / disable DPS mode of one or more subordinate non-AP STAs of the non-AP MLD;

[0373] Optionally, when the first field is set to 1, it indicates enable DPS Mode; when it is set to 0, it indicates disable DPS Mode.

[0374] (2) The third field indicates whether the second field exists in the first wireless frame.

[0375] Optionally, the third field may be a DPS Bitmap Present identifier; the third field device is 0, indicating that the second field does not exist in the first wireless frame, and the affiliated non-AP STA corresponding to the first wireless frame link sends the first wireless frame to perform the Enable / Disable DPS Mode operation identified by the first field; the third field is set to 1, the second field exists in the first wireless frame, indicating that one or more affiliated non-AP STAs perform the Enable / Disable DPS Mode operation identified by the first field.

[0376] (3) Optional second field: When the third field is set to 1, the first radio frame may include a second field for instructing one or more affiliated non-AP STAs to perform the Enable / Disable DPS Mode operation identified by the first field.

[0377] Optionally, the second field is a 16-bit DPS Mode bitmap field, where each bit corresponds to a link, for example, Bit0 to Bit15 correspond to Link0 to Link15 respectively. When the bit is set to 1, it indicates that the attached non-AP STA working in the corresponding link performs the Enable / Disable DPS Mode operation identified by the first field; when the bit is set to 0, it indicates that the attached non-AP STA working in the corresponding link does not perform the Enable / Disable DPS Mode operation identified by the first field.

[0378] Note: When the first field indicates Enable DPS Mode, in the second field, except for the bit corresponding to the link where the attached non-AP STA needs to enable DPS Mode, the bits corresponding to other enabled links are set to 0, and the bits corresponding to the disabled links are set to Reserved or set to 0.

[0379] When the first field indicates Disable DPS Mode, in the second field, except for the bits corresponding to the affiliated non-AP STA links that need to Disable DPS Mode, the bits corresponding to the enabled links that are currently not DPS-enabled are set to 0, and the bits corresponding to the disabled links are set to Reserved or set to 0.

[0380] Optionally, the formats of the first field, the second field and the third field in the first wireless frame may refer to Table 1.

[0381] In some embodiments, based on the different meanings of the first field and the second field in the first radio frame, combined with the following different situations, the following examples may be included:

[0382] Embodiment 1: In the case where the non-AP MLD requests the sending of the first radio frame in the dependent non-AP STA DisableDPS mode, the key fields in the first radio frame may be set to:

[0383] The first field is set to 0;

[0384] The third field is set to 0;

[0385] The second field is not included.

[0386] Embodiment 2: In the case where non-AP MLD requests one or more attached non-APs SAT Disable DPS mode, the key fields in the first radio frame may be set to:

[0387] The first field is set to 0;

[0388] The third field is set to 1;

[0389] Contains the second field.

[0390] For example, when the second field is set to 00010110 01000000, the second field can identify: four subordinate non-AP STAs corresponding to Link3, Link5, Link6 and Link9 are in Disable DPS mode, and subordinate non-AP STAs corresponding to other links do not perform any operation.

[0391] 2. After receiving the first radio frame, the AP MLD sends a second radio frame to the non-AP MLD in response. The second radio frame indicates that the AP MLD is ready to serve the non-AP MLD in the mode indicated by the first radio frame.

[0392] Optionally, when the second wireless frame includes a first field, a second field and a third field, the corresponding content of the second wireless frame should be set consistent with the corresponding content in the first wireless frame.

[0393] 3. After receiving the second radio frame, the non-AP MLD performs at least one of the following operations:

[0394] (1) If the first radio frame does not include the second field, the attached non-APSTA that sends the first radio frame performs the Enable / Disable DPS Mode operation indicated by the first field;

[0395] 1) If the DPS mode is enabled (for example, the first field is set to 1), after the non-AP MLD receives the second radio frame, the affiliated non-AP STA that sent the first radio frame switches to the low-capability mode within a first delay time (i.e., the first delay) and enables the DPS mode;

[0396] 2) If the DPS mode is disabled (for example, the first field is set to 0), among all non-AP STAs in the non-AP MLD, if, when sending the first radio frame, the subordinate non-AP STA sending the first radio frame is in low-capability communication mode, after receiving the second radio frame, it switches to high-capability mode within a second delay time (i.e., the second delay), and the DPS mode is disabled; if, when sending the first radio frame, the subordinate non-AP STA sending the first radio frame is in high-capability communication mode, after receiving the second radio frame, the DPS mode is disabled;

[0397] (2) If the first radio frame includes the second field, the attached non-AP STA corresponding to the link with the bit of the first subfield set to 1 performs the Enable / Disable DPS Mode operation identified by the first field.

[0398] 1) If the DPS mode is enabled (for example, the first field is set to 1), after the non-AP MLD receives the second radio frame, the attached non-AP STA corresponding to the link with the bit in the third field set to 1 switches to the low-capability mode, Enable DPS mode, within the third delay time (i.e., the corresponding third delay);

[0399] 2) If it is Disable DPS mode (for example, the first field is set to 0), for the affiliated non-AP STA corresponding to the bit link in which the third field is set to 1, if it is in low-capability communication mode when sending the first radio frame, after receiving the second radio frame, it switches to high-capability mode within the fourth delay time (i.e., the corresponding fourth delay), DisableDPS mode; if it is in high-capability communication mode when sending the first radio frame, after receiving the second radio frame, it is DisableDPS mode within the fourth delay time (i.e., the corresponding fourth delay).

[0400] In some embodiments, the first delay time, the second delay time, the third delay time, and the fourth delay time may be exchanged between the non-AP MLD and the AP MLD before sending the first radio frame or carried in the first radio frame, or may be carried in other radio frames (e.g., the third radio frame).

[0415] The second field indicates: at least one affiliated non-AP STA that requests to enable or disable the dynamic power saving mode.

[0416] In the above embodiment, the first field in the first radio frame can be used to identify the dynamic power saving mode requested by the non-AP MLD, that is, to enable or disable the dynamic power saving mode; and the second field in the first radio frame can be used to identify the subordinate non-AP STAs of the non-AP MLD that need to enable or disable the dynamic power saving mode.

[0417] Optionally, in the embodiment of the present disclosure, the first radio frame further includes:

[0418] The third field identifies whether the first wireless frame contains the second field.

[0419] In the above embodiment, whether the second field is included in the first radio frame may be identified by the third field.

[0420] Optionally, in an embodiment of the present disclosure, the third field includes a dynamic power saving mode bitmap present DPS BitmapPresent identifier;

[0421] The DPS Bitmap Present identifier is set to a first parameter value, and the first radio frame includes the second field;

[0422] The DPS Bitmap Present identifier is set to a second parameter value, and the first radio frame does not include the second field.

[0423] In the above embodiment, whether the first radio frame includes the second field may be specifically identified by using the parameter value of the DPS Bitmap Present identifier.

[0424] Optionally, in an embodiment of the present disclosure, the first radio frame does not include the second field, and the first radio frame requests: an affiliated non-AP STA operating in the first link to perform an operation identified by the first field;

[0426] The first radio frame includes the second field, and the first radio frame requests: the subordinate non-AP STA indicated by the second field to perform the operation identified by the first field.

[0434] In the second field, the bits corresponding to the enabled links for which the dynamic power saving mode is not enabled are set to a fourth parameter value;

[0435] In the second field, bits corresponding to disabled links are set to a fourth parameter value.

[0436] In the above embodiment, when the first field indicates that the dynamic power saving mode is turned off, the parameter value of each field in the first wireless frame can be determined by whether the link established between the non-APMLD and the AP MLD is enabled, and whether the affiliated non-AP STA under each enabled link needs to enable or disable the dynamic power saving mode.

[0459] Optionally, in the embodiment of the present disclosure, the method further includes:

[0460] Sending a third radio frame to the AP MLD; wherein the third radio frame carries delay information for the subordinate non-AP STA of the non-AP MLD to switch between the first capability communication mode and the second capability communication mode.
