The statement of the description object refers to the description in the context of the claims or embodiments, and should not constitute unnecessary restrictions due to the use of prefixes. For example, if the description object is a "field", the ordinal number before the "field" in the "first field" and the "second field" does not limit the position or order between the "fields", and the "first" and "second" do not limit whether the "fields" they modify are in the same message, nor do they limit the order of the "first field" and the "second field". For another example, if the description object is a "level", the ordinal number before the "level" in the "first level" and the "second level" does not limit the priority between the "levels". For another example, the number of description objects is not limited by the ordinal number, and can be one or more. Taking the "first device" as an example, the number of "devices" can be one or more. In addition, the objects modified by different prefixes may be the same or different. For example, if the description object is "device", then the "first device" and the "second device" may be the same device or different devices, and their types may be the same or different. For another example, if the description object is "information", then the "first information" and the "second information" may be the same information or different information, and their contents may be the same or different.

[0140] In some embodiments, “including A”, “comprising A”, “used to indicate A”, and “carrying A” can be interpreted as directly carrying A or indirectly indicating A.

[0145] In addition, each element, each row, or each column in the table of the embodiments of the present disclosure may be implemented as an independent embodiment, and the combination of any elements, any rows, and any columns may also be implemented as an independent embodiment.

[0146] Figure 1 It is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0147] like Figure 1 As shown, the communication system 100 includes a Non-AP MLD 101 and an AP MLD 102 .

[0148] Non-AP MLD101 and AP MLD102 support Multi-Link Operation (MLO) technology. To achieve higher throughput, lower network latency and higher reliability, the MLO technology allows Non-AP MLD101 and AP MLD102 to establish multiple communication links across frequency bands through Multi-Link Setup frame negotiation, and then enable the established multi-links through the Traffic-to-link Mapping mechanism.

[0149] In some embodiments, each of the AP MLD102's subordinate APs is equivalent to a bridge connecting a wired network and a wireless network, and its main function is to connect various wireless network clients together and then connect the wireless network to Ethernet. Specifically, each of the AP MLD102's subordinate APs can be a terminal device or a network device with a wireless fidelity chip.

[0150] In some embodiments, each subordinate STA of the Non-AP MLD 101 is a device including a wireless communication chip supporting WiFi communication function, a wireless sensor or a wireless communication terminal. Optionally, the wireless communication terminal can be, for example, a mobile phone, a wearable device, an Internet of Things device supporting WiFi communication function, a car with WiFi communication function, a smart car, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in smart grid, a wireless terminal device in transportation safety, a wireless terminal device in smart city, and at least one of a wireless terminal device in smart home, but not limited thereto.

[0151] Considering the limited receiving capability of Non-AP MLD101, after Non-AP MLD101 and AP MLD102 successfully establish multi-link and enable the communication link, Non-AP MLD101 and AP MLD102 negotiate to establish the enhanced multi-link mode and the communication link in the enhanced multi-link mode through the EML Operation ModeNotification frame.

[0152] The enhanced multi-link mode includes an enhanced multi-link single radio (Enhanced Multi Link Single Radio, EMLSR) mode and an enhanced multi-link multi-radio (Enhanced Multi-link Multi-radio, EMLMR) mode.

[0153] After the STA belonging to the Non-AP MLD 101 and working on the EMLSR link or the EMLMR link enters the active state or the awake state, it monitors the channel and receives the initial control frame sent by the AP MLD in the orthogonal frequency division multiplexing PPDU type and the non-high throughput repeated PPDU type.

[0154] When AP MLD102 enables a new communication link or invalidates an enabled communication link, the EMLSR link or EMLMR link corresponding to Non-AP MLD101 may change. For example, when a new communication link is enabled, the STA attached to Non-AP MLD101 corresponding to the newly enabled communication link may intend to be in EMLSR mode or EMLMR mode; or, one of the communication links in the EMLSR link or EMLMR link happens to be invalidated, and Non-AP MLD101 also needs to update the EMLSR link or EMLMR link. According to the existing mechanism, Non-AP MLD101 needs to negotiate the EMLSR link or EMLMR link with AP MLD102 through the EML Operation Notification frame every time a new communication link is enabled or an enabled communication link is invalidated. This method not only brings additional signaling overhead, but also affects transmission efficiency.

[0155] 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.

Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0159] Figure 2 It is a schematic diagram of the interaction of the communication method according to an embodiment of the present disclosure. Figure 2 The communication methods shown include:

[0160] Step S21: The Non-AP MLD determines under a first condition and sends a multi-link operation update request frame to the AP MLD, wherein the multi-link operation update request frame includes a first information field, and the first information field is used to indicate state information of an enhanced multi-link mode of the Non-AP MLD.

[0161] In some embodiments, the enhanced multi-link mode comprises an enhanced multi-link single radio EMLSR mode or an enhanced multi-link multi-radio EMLMR mode.

[0162] In some embodiments, the first condition includes at least one of the following:

[0163] When the Non-AP MLD works in enhanced multi-link mode, a new enabling communication link is added between the Non-AP MLD and the AP MLD;

[0164] When the Non-AP MLD operates in the enhanced multi-link mode, at least one enabled communication link of the Non-AP MLD in the enhanced multi-link mode fails.

[0165] As an example, when the Non-AP MLD operates in the EMLSR mode or the EMLMR mode, when a communication link is newly enabled between the Non-AP MLD and the AP MLD, the Non-AP MLD determines a multi-link operation update request frame.

[0166] As an example, in the case where the Non-AP MLD operates in the EMLSR mode, when at least one enabled EMLSR link of the Non-AP MLD in the EMLSR mode fails, the Non-AP MLD determines a multi-link operation update request frame.

[0167] As an example, in the case where the Non-AP MLD operates in the EMLMR mode, when at least one enabled EMLMR link of the Non-AP MLD in the EMLMR mode fails, the Non-AP MLD determines a multi-link operation update request frame.

[0168] In some embodiments, a multi-link operation update request (Multi-Link Operation UpdateRequest) frame includes a first information field, the first information field includes an enhanced multi-link control (EML Control) field, the enhanced multi-link control field includes an EMLSR mode (EMLSR Mode) field and an EMLMR mode (EMLMR Mode) field.

[0169] The EMLSR mode field indicates that the Non-AP MLD works in the EMLSR mode through a first value, and indicates that the Non-AP MLD does not work in the EMLSR mode through other values.

[0170] The first value may be 1, which is not limited here.

[0171] The EMLMR mode field indicates that the Non-AP MLD works in the EMLMR mode through the second value, and indicates that the Non-AP MLD does not work in the EMLMR mode through other values.

[0172] The second value may be 1, which is not limited here.

[0173] As an example, the first information domain includes an enhanced multi-link control domain, and the enhanced multi-link control domain includes an EMLSR mode domain and an EMLMR mode domain. When the identification value of the EMLSR mode domain is 1 and the identification value of the EMLMR mode domain is 0, it is used to indicate that the Non-AP MLD works in the EMLSR mode; when the identification value of the EMLSR mode domain is 0 and the identification value of the EMLMR mode domain is 1, it is used to indicate that the Non-AP MLD works in the EMLMR mode.

[0174] In some embodiments, when the Non-AP MLD operates in the EMLSR mode, the enhanced multi-link control field further includes an EMLSR link bitmap field; when the Non-AP MLD operates in the EMLMR mode, the enhanced multi-link control field further includes an EMLMR link bitmap field;

[0175] The EMLSR link bitmap field is used to indicate the EMLSR link when the Non-AP MLD works in the EMLSR mode, and the EMLMR link bitmap field is used to indicate the EMLMR link when the Non-AP MLD works in the EMLMR mode.

[0176] As an example, the Non-AP MLD determines a multi-link operation update request frame under a first condition, wherein the multi-link operation update request frame includes a first information field, the first information field includes an enhanced multi-link control field, and the enhanced multi-link control field includes an EMLSR mode field and an EMLMR mode field.

[0177] Among them, when the identification value of the EMLSR mode domain is 1 and the identification value of the EMLMR mode domain is 0, it is used to indicate that the Non-AP MLD works in the EMLSR mode. At this time, the enhanced multi-link control domain also includes an EMLSR link bitmap domain, and the EMLSR link bitmap domain is used to indicate the EMLSR link when the Non-AP MLD works in the EMLSR mode.

[0178] Among them, when the identification value of the EMLMR mode field is 0 and the identification value of the EMLMR mode field is 1, it is used to indicate that the Non-AP MLD works in the EMLMR mode. At this time, the enhanced multi-link control field also includes an EMLMR link bitmap field, and the EMLMR link bitmap field is used to indicate the EMLMR link when the Non-AP MLD works in the EMLMR mode.

[0179] In some embodiments, the enhanced multi-link control field further includes an EMLSR parameter update control (EMLSRParameter Update Control) field or an EMLMR parameter update control (EMLMR Parameter UpdateControl) field.

[0180] The EMLSR parameter update control field indicates the EMLSR parameter update through the third value, that is, indicates the update of the EMLSR parameters carried by the Basic Multi-Link element field in the process of associating the Non-AP MLD and the AP MLD.

[0181] The EMLMR parameter update control field indicates the EMLMR parameter update through the fourth value, that is, indicates the update of the EMLMR parameters carried by the Basic Multi-Link element field in the process of associating the Non-AP MLD and the AP MLD.

[0182] The third value and the fourth value may be 1, and are not limited here.

[0183] As an example, when the Non-AP MLD operates in the EMLSR mode, the multi-link operation update request frame includes a first information field, the first information field includes an enhanced multi-link control field, and the enhanced multi-link control field includes an EMLSR parameter update control field. When the identification value of the EMLSR parameter update control field is a third value, it is used to indicate an EMLSR parameter update, that is, to request an EMLSR parameter update.

[0184] As an example, when the Non-AP MLD operates in the EMLMR mode, the multi-link operation update request frame includes a first information field, the first information field includes an enhanced multi-link control field, and the enhanced multi-link control field includes an EMLMR parameter update control field. When the identification value of the EMLMR parameter update control field is a fourth value, it is used to indicate that an EMLMR parameter update is to be performed, that is, to request an EMLMR parameter update.

[0185] In some embodiments, when the enhanced multi-link control domain includes an EMLSR parameter update control (EMLSRParameter Update Control) domain, when the EMLSR parameter update control domain is used to indicate an EMLSR parameter update, the multi-link operation update request frame also includes a second information domain, and the second information domain is used to indicate the EMLSR parameters to be updated.

[0186] In the case where the enhanced multi-link control field includes an EMLMR parameter update control (EMLMR Parameter UpdateControl) field, when the EMLMR parameter update control field is used to indicate an EMLMR parameter update, the multi-link operation update request frame also includes a third information field, and the third information field is used to indicate the EMLMR parameters to be updated.

[0187] Optionally, the EMLSR parameter to be updated includes at least one of the following:

[0188] Minimum medium access control (MAC) padding delay for initial frames in EMLSR mode;

[0189] The shortest delay for the EMLSR link to switch from the frame exchange state to the listening state in EMLSR mode.

[0190] Among them, the second information field includes at least one item in the third sub-information field or the fourth sub-information field, the third sub-information field is used to indicate the minimum MAC filling delay of the initial frame in the EMLSR mode, and the fourth sub-information field is used to indicate the shortest delay for the EMLSR link to switch from the frame exchange state to the listening state in the EMLSR mode.

[0191] Among them, the minimum MAC padding delay of the initial frame in the EMLSR mode may be the EMLSR Padding Delay, and the shortest delay for the EMLSR link to switch from the frame exchange state to the listening state in the EMLSR mode may be the EMLSR Transition Delay.

[0192] Optionally, the EMLMR parameter to be updated includes at least one of the following:

[0193] Minimum medium access control (MAC) padding delay for initial frames in EMLMR mode;

[0194] The shortest delay for the EMLMR link to switch from the frame exchange state to the listening state in EMLMR mode.

[0195] Among them, the third information field includes at least one item in the first sub-information field or the second sub-information field, the first sub-information field is used to indicate the minimum MAC filling delay of the initial frame in the EMLMR mode, and the second sub-information field is used to indicate the shortest delay for the EMLMR link to switch from the frame exchange state to the listening state in the EMLMR mode.

[0196] Among them, the minimum MAC padding delay of the initial frame in the EMLMR mode may be the EMLMR Padding Delay, and the shortest delay for the EMLMR link to switch from the frame exchange state to the listening state in the EMLMR mode may be the EMLMRTransition Delay.

[0197] Step S22: The AP MLD sends a multi-link operation update response frame to the Non-AP MLD within the conversion timeout period, or the AP MLD does not send a multi-link operation update response frame within the conversion timeout period.

[0198] In some embodiments, the AP MLD sends a multi-link operation update response (Multi-Link Operation Update Response) frame to the Non-AP MLD within a transition timeout period (Transition Timeout), and the multi-link operation update response frame does not include the first information field.

[0199] The transition timeout is indicated by the transition timeout (TransitionTimeout) field when the Non-AP MLD and the AP MLD establish an association. The message frame in the process of associating the Non-AP MLD and the AP MLD includes the Basic Multi-Linkelement field, the Basic Multi-Link element field includes the EML Capabilities field, and the EML Capabilities field includes the Transition Timeout field.

[0200] In some embodiments, the AP MLD does not send a multi-link operation update response frame within the transition timeout period.

[0201] In some embodiments, the AP MLD sends a multi-link operation update response (Multi-Link Operation Update Response) frame to the Non-AP MLD within a transition timeout period (Transition Timeout), and the multi-link operation update response frame includes a first information field.

[0202] Wherein, in the case where the first information field of the multi-link operation update request frame includes an enhanced multi-link control (EMLControl) field, the first information field of the multi-link operation update response frame may include an enhanced multi-link control field.

[0203] As an example, the first information field in the multi-link operation update response frame may include an enhanced multi-link control field, and the enhanced multi-link control field may include an EMLSR mode field and an EMLMR mode field.

[0205] As an example, the first information field in the multi-link operation update response frame may include an enhanced multi-link control field, and when the Non-AP MLD operates in the EMLMR mode, the enhanced multi-link control field may include an EMLMR link bitmap field.

[0206] As an example, the first information field in the multi-link operation update response frame may include an enhanced multi-link control field, and the enhanced multi-link control field may include an EMLSR parameter update control field.

[0207] As an example, the first information field in the multi-link operation update response frame may include an enhanced multi-link control field, and the enhanced multi-link control field may include an EMLMR parameter update control field.

[0208] As an example, the multi-link operation update response frame may further include a second information field. That is, when the first information field in the multi-link operation update response frame includes an enhanced multi-link control field, and the enhanced multi-link control field includes an EMLSR parameter update control (EMLSR Parameter Update Control) field, when the EMLSR parameter update control field is used to indicate an EMLSR parameter update, the multi-link operation update response frame also includes a second information field for indicating the EMLSR parameters to be updated.

[0209] As an example, the multilink operation update response frame may further include a third information field. That is, when the first information field in the multilink operation update response frame includes an enhanced multilink control field, and the enhanced multilink control field includes an EMLMR parameter update control (EMLMR Parameter Update Control) field, when the EMLMR parameter update control field is used to indicate that an EMLMR parameter update is to be performed, the multilink operation update response frame further includes a third information field for indicating the EMLMR parameters to be updated.

[0210] Optionally, the EMLSR parameter to be updated includes at least one of the following:

[0211] Minimum medium access control (MAC) padding delay for initial frames in EMLSR mode;

[0212] The shortest delay for the EMLSR link to switch from the frame exchange state to the listening state in EMLSR mode.

[0213] Among them, the second information field includes at least one item in the third sub-information field or the fourth sub-information field, the third sub-information field is used to indicate the minimum MAC filling delay of the initial frame in the EMLSR mode, and the fourth sub-information field is used to indicate the shortest delay for the EMLSR link to switch from the frame exchange state to the listening state in the EMLSR mode.

[0214] Among them, the minimum MAC padding delay of the initial frame in the EMLSR mode may be the EMLSR Padding Delay, and the shortest delay for the EMLSR link to switch from the frame exchange state to the listening state in the EMLSR mode may be the EMLSR Transition Delay.

[0215] Optionally, the EMLMR parameter to be updated includes at least one of the following:

[0216] Minimum medium access control (MAC) padding delay for initial frames in EMLMR mode;

[0218] The second information field includes at least one item in the first sub-information field or the second sub-information field, the first sub-information field is used to indicate the minimum MAC filling delay of the initial frame in the EMLMR mode, and the second sub-information field is used to indicate the shortest delay for the EMLMR link to switch from the frame exchange state to the listening state in the EMLMR mode.

[0220] As an example, the multi-link operation update request frame includes a first information field and a second information field.

[0221] Among them, the first information field in the multi-link operation update request frame includes an enhanced multi-link control field, the enhanced multi-link control field includes an EMLSR mode field and an EMLMR mode field, and when the Non-AP MLD works in EMLSR mode, the enhanced multi-link control field also includes an EMLSR link bitmap (EMLSR Link Bitmap) field and an EMLSR parameter update control (EMLSRParameter Update Control) field.

[0222] The multi-link operation update request frame response frame includes a second information field for indicating the EMLSR parameters to be updated. The second information field includes a third sub-information field and a fourth sub-information field, the third sub-information field is used to indicate the minimum MAC padding delay of the initial frame in the EMLSR mode, and the fourth sub-information field is used to indicate the shortest delay for the EMLSR link to switch from the frame exchange state to the listening state in the EMLSR mode.

[0223] In this case, the multi-link operation update response frame may include at least one of the first information field or the second information field.

[0224] Furthermore, the first information field in the multi-link operation update response frame may include an enhanced multi-link control field, and the enhanced multi-link control field may include an EMLSR mode field and an EMLMR mode field.

[0225] Furthermore, when the Non-AP MLD operates in the EMLSR mode, the multi-link operation update response frame includes an enhanced multi-link control field, and the enhanced multi-link control field may include at least one of an EMLSR link bitmap field or an EMLSR parameter update control field.

[0226] Furthermore, when the multi-link operation update response frame includes the second information field, the second information field may include at least one of the third sub-information field or the fourth sub-information field.

[0227] As an example, the multi-link operation update request frame includes a first information field and a third information field.

[0228] Among them, the first information field in the multi-link operation update request frame includes an enhanced multi-link control field, the enhanced multi-link control field includes an EMLSR mode field and an EMLMR mode field, and when the Non-AP MLD works in the EMLMR mode, the enhanced multi-link control field also includes an EMLMR link bitmap (EMLMR Link Bitmap) field and an EMLMR parameter update control (EMLMRParameter Update Control) field.

[0229] The multi-link operation update request frame response frame includes a third information field for indicating the EMLMR parameters to be updated. The third information field includes a first sub-information field and a second sub-information field, the first sub-information field is used to indicate the minimum MAC padding delay of the initial frame in the EMLMR mode, and the second sub-information field is used to indicate the shortest delay for the EMLMR link to switch from the frame exchange state to the listening state in the EMLMR mode.

[0230] In this case, the multi-link operation update response frame may include at least one of the first information field or the third information field.

[0231] Furthermore, the first information field in the multi-link operation update response frame may include an enhanced multi-link control field, and the enhanced multi-link control field may include an EMLSR mode field and an EMLMR mode field.

[0232] Furthermore, when the Non-AP MLD operates in the EMLMR mode, the multi-link operation update response frame includes an enhanced multi-link control field, and the enhanced multi-link control field may include at least one of an EMLMR link bitmap field or an EMLMR parameter update control field.

[0233] Furthermore, when the multi-link operation update response frame includes the third information field, the third information field may include at least one item of the first sub-information field or the second sub-information field.

[0234] Step S23, when the Non-AP MLD receives the multi-link operation update response frame within the conversion timeout period, or when the Non-AP MLD does not receive the multi-link operation update response frame within the conversion timeout period, the Non-AP MLD performs link update for the enhanced multi-link mode.

[0235] In some embodiments, if the Non-AP MLD does not receive a multi-link operation update response frame within a switching timeout period, the Non-AP MLD may perform a link update for the enhanced multi-link mode.

[0236] If the Non-AP MLD works in the EMLSR mode, the Non-AP MLD performs EMLSR link update. If the Non-AP MLD works in the EMLMR mode, the Non-AP MLD performs EMLMR link update.

[0239] In some embodiments, if the Non-AP MLD receives a multi-link operation update response frame sent by the AP MLD within the conversion time, the Non-AP MLD may perform a link update for the enhanced multi-link mode.

[0240] If the Non-AP MLD works in the EMLSR mode, the Non-AP MLD performs EMLSR link update. If the Non-AP MLD works in the EMLMR mode, the Non-AP MLD performs EMLMR link update.

Alternatively, when the multi-link operation update response frame includes a first information field, the first information field includes an enhanced multi-link control field, and the enhanced multi-link control field includes an EMLSR link bitmap field, the Non-AP MLD may perform an EMLSR link update according to the EMLSR link indicated by the EMLSR link bitmap field.

[0242] Optionally, when the multi-link operation update request frame includes the first information field, the first information field includes the enhanced multi-link control field, and the enhanced multi-link control field includes the EMLMR link bitmap field, the Non-AP MLD may perform an EMLMR link update according to the EMLMR link indicated by the EMLMR link bitmap field.

[0243] Step S24, the Non-AP MLD determines whether the multi-link operation update request frame and the multi-link operation update response frame include an enhanced multi-link mode parameter update control field.

[0244] The enhanced multi-link mode parameter update control field includes an EMLSR parameter update control field or an EMLMR parameter update control field.

[0245] That is, the Non-AP MLD determines whether the multi-link operation update request frame and the multi-link operation update response frame include one of the EMLSR parameter update control field or the EMLMR parameter update control field.

[0246] As an example, when the Non-AP MLD operates in the EMLSR mode, the Non-AP MLD determines whether the multi-link operation update request frame and the multi-link operation update response frame include the EMLSR parameter update control field; when the Non-AP MLD operates in the EMLMR mode, the Non-AP MLD determines whether the multi-link operation update request frame and the multi-link operation update response frame include the EMLMR parameter update control field.

[0247] If the multi-link operation update request frame and the multi-link operation update response frame include an enhanced multi-link mode parameter update control field, step S26 is executed; otherwise, step S25 is executed.

[0248] That is, when the Non-AP MLD works in the EMLSR mode, if the multi-link operation update request frame and the multi-link operation update response frame include the EMLSR parameter update control field, step S26 is executed, otherwise step S25 is executed. When the Non-AP MLD works in the EMLMR mode, if the multi-link operation update request frame and the multi-link operation update response frame include the EMLMR parameter update control field, step S26 is executed, otherwise step S25 is executed.

[0249] Step S25: Non-AP MLD does not update parameters for the enhanced multi-link mode.

[0250] In some embodiments, when the Non-AP MLD operates in the EMLSR mode, the Non-AP MLD does not perform EMLSR parameter update. When the Non-AP MLD operates in the EMLMR mode, the Non-AP MLD does not perform EMLMR parameter update.

[0251] Step S26: The Non-AP MLD determines whether the enhanced multi-link mode update control field indicates to update parameters for the enhanced multi-link mode.

[0252] In some embodiments, if the multilink operation update request frame and the multilink operation update response frame include an EMLSR parameter update control field, the Non-AP MLD determines whether the EMLSR parameter update control field indicates an EMLSR parameter update through a third value.

[0253] If the multi-link operation update request frame and the multi-link operation update response frame include the EMLMR parameter update control field, the Non-AP MLD determines whether the EMLSR parameter update control field indicates to perform EMLSR parameter update through the fourth value.

[0254] If it is determined that the enhanced multi-link mode update control field is used to instruct to update parameters for the enhanced multi-link mode, step S27 is executed; otherwise, step S25 is executed.

[0255] That is, when the Non-AP MLD works in the EMLSR mode, if the EMLSR parameter update control field in the multi-link operation update request frame and the multi-link operation update response frame indicates that the EMLSR parameter update is to be performed through the third value, then step S27 is executed, otherwise, step S25 is executed. When the Non-AP MLD works in the EMLMR mode, if the EMLMR parameter update control field in the multi-link operation update request frame and the multi-link operation update response frame indicates that the EMLMR parameter update is to be performed through the fourth value, then step S27 is executed, otherwise, step S25 is executed.

[0256] Step S27, the Non-AP MLD determines whether the multi-link operation update request frame and the multi-link operation update response frame include an information field for indicating the enhanced multi-link mode parameters to be updated.

[0257] The information field for indicating the enhanced multi-link mode parameters to be updated includes a second information field for indicating the EMLSR parameters to be updated and a third information field for indicating the EMLMR parameters to be updated.

[0258] In some embodiments, when the Non-AP MLD operates in the EMLSR mode, the Non-AP MLD determines whether the multi-link operation update request frame and the multi-link operation update response frame include the second information field. If the second information field is included, step S29 is executed, otherwise step S28 is executed. When the Non-AP MLD operates in the EMLMR mode, the Non-AP MLD determines whether the multi-link operation update request frame and the multi-link operation update response frame include the third information field. If the third information field is included, step S29 is executed, otherwise step S28 is executed.

[0259] The second information field is used to indicate the EMLSR parameters to be updated, and the third information field is used to indicate the EMLMR parameters to be updated.

[0260] Step S28: Non-AP MLD updates the enhanced multi-link mode parameters carried in the basic multi-link element field.

[0261] In some embodiments, when Non-AP MLD operates in EMLSR mode, Non-AP MLD can update the EMLSR parameters carried in the Basic Multi-Link element field in the message frame during the association process between Non-AP MLD and AP MLD. When Non-AP MLD operates in EMLMR mode, Non-AP MLD can update the EMLMR parameters carried in the Basic Multi-Link element field in the message frame during the association process between Non-AP MLD and AP MLD.

[0262] Step S29: the Non-AP MLD updates the parameters of the enhanced multi-link mode according to the enhanced multi-link mode parameters to be updated indicated by the corresponding information field.

[0263] In some embodiments, when the Non-AP MLD works in the EMLSR mode, the Non-AP MLD may update the EMLSR parameters according to the EMLSR parameters to be updated indicated by the second information field.

[0264] Among them, when the second information field in the multi-link operation update request frame or the multi-link operation update response frame includes the third sub-information field, the Non-AP MLD can update the minimum MAC padding delay of the initial frame in the EMLSR mode indicated by the third sub-information field, such as updating the EMLSR Padding Delay parameter in the EMLSR mode.

[0265] Among them, when the second information field in the multi-link operation update request frame or the multi-link operation update response frame includes the fourth sub-information field, the Non-AP MLD can update the shortest delay for the EMLSR link to switch from the frame exchange state to the listening state in the EMLSR mode indicated by the fourth sub-information field, such as updating the EMLSR Transition Delay parameter in the EMLSR mode.

[0266] In some embodiments, when the Non-AP MLD works in the EMLMR mode, the Non-AP MLD may perform EMLMR parameter setting according to the EMLMR parameter indicated by the third information field.

[0267] Among them, when the third information field in the multi-link operation update request frame or the multi-link operation update response frame includes the first sub-information field, the Non-AP MLD can update the minimum MAC padding delay of the initial frame in the EMLMR mode indicated by the first sub-information field, such as updating the EMLMR Padding Delay parameter in the EMLMR mode.

[0268] Among them, when the third information field in the multi-link operation update request frame or the multi-link operation update response frame includes the second sub-information field, the Non-AP MLD can update the shortest delay for the EMLMR link to switch from the frame exchange state to the listening state in the EMLMR mode indicated by the second sub-information field, such as updating the EMLMR Transition Delay parameter in the EMLMR mode.

For example, any one of steps S21-S23 may be implemented as an independent embodiment, steps S21-S22 may be implemented as an independent embodiment, and steps S21-S29 may be implemented as an independent embodiment, but are not limited thereto.

[0270] Figure 3 FIG. 1 is one of the flow charts of the communication method according to the embodiment of the present disclosure. Figure 3 As shown, the method is performed by the Non-AP MLD, and the method includes:

[0271] Step S31: determining a multi-link operation update request frame under a first condition, wherein the multi-link operation update request frame includes a first information field, and the first information field is used to indicate state information of an enhanced multi-link mode of the Non-AP MLD.

[0272] In some embodiments, the enhanced multi-link mode comprises an enhanced multi-link single radio EMLSR mode or an enhanced multi-link multi-radio EMLMR mode.

[0273] In some embodiments, the first condition includes at least one of the following:

[0274] In some embodiments, the first condition includes at least one of the following:

[0275] When the Non-AP MLD works in enhanced multi-link mode, a new enabling communication link is added between the Non-AP MLD and the AP MLD;

[0276] When the Non-AP MLD operates in the enhanced multi-link mode, at least one enabled communication link of the Non-AP MLD in the enhanced multi-link mode fails.

[0277] As an example, when the Non-AP MLD operates in the EMLSR mode or the EMLMR mode, when a communication link is newly enabled between the Non-AP MLD and the AP MLD, the Non-AP MLD determines a multi-link operation update request frame.

[0278] As an example, in the case where the Non-AP MLD operates in the EMLSR mode, when at least one enabled EMLSR link of the Non-AP MLD in the EMLSR mode fails, the Non-AP MLD determines a multi-link operation update request frame.

[0279] As an example, in the case where the Non-AP MLD operates in the EMLMR mode, when at least one enabled EMLMR link of the Non-AP MLD in the EMLMR mode fails, the Non-AP MLD determines a multi-link operation update request frame.

[0280] In some embodiments, a multi-link operation update request (Multi-Link Operation UpdateRequest) frame includes a first information field, the first information field includes an enhanced multi-link control (EML Control) field, the enhanced multi-link control field includes an EMLSR mode (EMLSR Mode) field and an EMLMR mode (EMLMR Mode) field.

[0281] The EMLSR mode field indicates that the Non-AP MLD works in the EMLSR mode through a first value, and indicates that the Non-AP MLD does not work in the EMLSR mode through other values.

[0282] The first value may be 1, which is not limited here.

[0283] The EMLMR mode field indicates that the Non-AP MLD works in the EMLMR mode through the second value, and indicates that the Non-AP MLD does not work in the EMLMR mode through other values.

[0284] The second value may be 1, which is not limited here.

[0285] As an example, the first information domain includes an enhanced multi-link control domain, and the enhanced multi-link control domain includes an EMLSR mode domain and an EMLMR mode domain. When the identification value of the EMLSR mode domain is 1 and the identification value of the EMLMR mode domain is 0, it is used to indicate that the Non-AP MLD works in the EMLSR mode; when the identification value of the EMLSR mode domain is 0 and the identification value of the EMLMR mode domain is 1, it is used to indicate that the Non-AP MLD works in the EMLMR mode.

[0286] In some embodiments, when the Non-AP MLD operates in the EMLSR mode, the enhanced multi-link control field further includes an EMLSR link bitmap field; when the Non-AP MLD operates in the EMLMR mode, the enhanced multi-link control field further includes an EMLMR link bitmap field;

[0287] The EMLSR link bitmap field is used to indicate the EMLSR link when the Non-AP MLD works in the EMLSR mode, and the EMLMR link bitmap field is used to indicate the EMLMR link when the Non-AP MLD works in the EMLMR mode.

[0288] As an example, the Non-AP MLD determines a multi-link operation update request frame under a first condition, wherein the multi-link operation update request frame includes a first information field, the first information field includes an enhanced multi-link control field, and the enhanced multi-link control field includes an EMLSR mode field and an EMLMR mode field.

[0289] Among them, when the identification value of the EMLSR mode domain is 1 and the identification value of the EMLMR mode domain is 0, it is used to indicate that the Non-AP MLD works in the EMLSR mode. At this time, the enhanced multi-link control domain also includes an EMLSR link bitmap domain, and the EMLSR link bitmap domain is used to indicate the EMLSR link when the Non-AP MLD works in the EMLSR mode.

[0290] Among them, when the identification value of the EMLMR mode field is 0 and the identification value of the EMLMR mode field is 1, it is used to indicate that the Non-AP MLD works in the EMLMR mode. At this time, the enhanced multi-link control field also includes an EMLMR link bitmap field, and the EMLMR link bitmap field is used to indicate the EMLMR link when the Non-AP MLD works in the EMLMR mode.

[0291] In some embodiments, the enhanced multi-link control region further includes an EMLSR parameter update control region or an EMLMR parameter update control region.

[0292] The EMLSR parameter update control field indicates the EMLSR parameter update through the third value, that is, indicates the update of the EMLSR parameters carried by the Basic Multi-Link element field in the process of associating Non-AP MLD and AP MLD.

[0293] The EMLMR parameter update control field indicates the EMLMR parameter update through the fourth value, that is, indicates the update of the EMLMR parameters carried by the Basic Multi-Link element field in the process of associating the Non-AP MLD and the AP MLD.

[0294] The third value and the fourth value may be 1, and are not limited here.

[0295] As an example, when the Non-AP MLD operates in the EMLSR mode, the multi-link operation update request frame includes a first information field, the first information field includes an enhanced multi-link control field, and the enhanced multi-link control field includes an EMLSR parameter update control field. When the identification value of the EMLSR parameter update control field is a third value, it is used to indicate an EMLSR parameter update, that is, to request an EMLSR parameter update.

When the identification value of the EMLMR parameter update control field is a fourth value, it is used to indicate that an EMLMR parameter update is to be performed, that is, to request an EMLMR parameter update.

[0297] In some embodiments, when the enhanced multi-link control domain includes an EMLSR parameter update control (EMLSRParameter Update Control) domain, when the EMLSR parameter update control domain is used to indicate an EMLSR parameter update, the multi-link operation update request frame also includes a second information domain, and the second information domain is used to indicate the EMLSR parameters to be updated.

[0298] In the case where the enhanced multi-link control field includes an EMLMR parameter update control (EMLMR Parameter UpdateControl) field, when the EMLMR parameter update control field is used to indicate an EMLMR parameter update, the multi-link operation update request frame also includes a third information field, and the third information field is used to indicate the EMLMR parameters to be updated.

[0299] Optionally, the EMLSR parameter to be updated includes at least one of the following:

[0300] Minimum medium access control (MAC) padding delay for initial frames in EMLSR mode;

[0301] The shortest delay for the EMLSR link to switch from the frame exchange state to the listening state in EMLSR mode.

[0302] Among them, the second information field includes at least one item in the third sub-information field or the fourth sub-information field, the third sub-information field is used to indicate the minimum MAC filling delay of the initial frame in the EMLSR mode, and the fourth sub-information field is used to indicate the shortest delay for the EMLSR link to switch from the frame exchange state to the listening state in the EMLSR mode.

[0303] Among them, the minimum MAC padding delay of the initial frame in the EMLSR mode may be the EMLSR Padding Delay, and the shortest delay for the EMLSR link to switch from the frame exchange state to the listening state in the EMLSR mode may be the EMLSR Transition Delay.

[0304] Optionally, the EMLMR parameter to be updated includes at least one of the following:

[0305] Minimum medium access control (MAC) padding delay for initial frames in EMLMR mode;

[0306] The shortest delay for the EMLMR link to switch from the frame exchange state to the listening state in EMLMR mode.

[0307] Among them, the third information field includes at least one item in the first sub-information field or the second sub-information field, the first sub-information field is used to indicate the minimum MAC filling delay of the initial frame in the EMLMR mode, and the second sub-information field is used to indicate the shortest delay for the EMLMR link to switch from the frame exchange state to the listening state in the EMLMR mode.

[0308] Among them, the minimum MAC padding delay of the initial frame in the EMLMR mode may be the EMLMR Padding Delay, and the shortest delay for the EMLMR link to switch from the frame exchange state to the listening state in the EMLMR mode may be the EMLMRTransition Delay.

[0309] Step S32: Send a multi-link operation update request frame to the AP MLD.

[0310] Figure 4 FIG. 2 is a flow chart of a communication method according to an embodiment of the present disclosure. Figure 4 As shown, the method is performed by the Non-AP MLD, and the method includes:

[0311] Step S41: determining a multi-link operation update request frame under a first condition, wherein the multi-link operation update request frame includes a first information field, and the first information field is used to indicate state information of an enhanced multi-link mode of the Non-AP MLD.

[0312] Step S42: Send a multi-link operation update request frame to the AP MLD.

[0313] In some embodiments, the implementation of step S41-step S42 can be found in Figure 3 The implementation method shown in step S31-step S32 will not be repeated here.

[0314] Step S43: When a multi-link operation update response frame sent by the AP MLD is received within the conversion timeout period, or when a multi-link operation update response frame sent by the AP MLD is not received within the conversion timeout period, link update is performed for the enhanced multi-link mode.

[0315] In some embodiments, the multi-link operation update response frame is sent by the AP MLD to the Non-AP MLD within a transition timeout period (TransitionTimeout), and the multi-link operation update response frame does not include the first information field.

[0316] The transition timeout is indicated by the transition timeout (TransitionTimeout) field when the Non-AP MLD and the AP MLD establish an association. The message frame in the process of associating the Non-AP MLD and the AP MLD includes the Basic Multi-Linkelement field, the Basic Multi-Link element field includes the EML Capabilities field, and the EML Capabilities field includes the Transition Timeout field.

[0317] In some embodiments, the multi-link operation update response frame is sent by the AP MLD to the Non-AP MLD within a transition timeout period (TransitionTimeout), and the multi-link operation update response frame includes a first information field.

[0327] Minimum medium access control (MAC) padding delay for initial frames in EMLSR mode;

[0328] The shortest delay for the EMLSR link to switch from the frame exchange state to the listening state in EMLSR mode.

[0336] As an example, the multi-link operation update request frame includes a first information field and a second information field.

[0337] Among them, the first information field in the multi-link operation update request frame includes an enhanced multi-link control field, the enhanced multi-link control field includes an EMLSR mode field and an EMLMR mode field, and when the Non-AP MLD works in EMLSR mode, the enhanced multi-link control field also includes an EMLSR link bitmap field and an EMLSR parameter update control field.

[0339] In this case, the multi-link operation update response frame may include at least one of the first information field or the second information field.

[0340] Furthermore, the first information field in the multi-link operation update response frame may include an enhanced multi-link control field, and the enhanced multi-link control field may include an EMLSR mode field and an EMLMR mode field.

[0341] Furthermore, when the Non-AP MLD operates in the EMLSR mode, the multi-link operation update response frame includes an enhanced multi-link control field, and the enhanced multi-link control field may include at least one of an EMLSR link bitmap field or an EMLSR parameter update control field.

[0342] Furthermore, when the multi-link operation update response frame includes the second information field, the second information field may include at least one of the third sub-information field or the fourth sub-information field.

[0343] As an example, the multi-link operation update request frame includes a first information field and a third information field.

[0344] Among them, the first information field in the multi-link operation update request frame includes an enhanced multi-link control field, the enhanced multi-link control field includes an EMLSR mode field and an EMLMR mode field, and when the Non-AP MLD works in EMLMR mode, the enhanced multi-link control field also includes an EMLMR link bitmap field and an EMLMR parameter update control field.

[0345] The multi-link operation update request frame response frame includes a third information field for indicating the EMLMR parameters to be updated. The third information field includes a first sub-information field and a second sub-information field, the first sub-information field is used to indicate the minimum MAC padding delay of the initial frame in the EMLMR mode, and the second sub-information field is used to indicate the shortest delay for the EMLMR link to switch from the frame exchange state to the listening state in the EMLMR mode.

[0346] In this case, the multi-link operation update response frame may include at least one of the first information field or the third information field.

[0347] Furthermore, the first information field in the multi-link operation update response frame may include an enhanced multi-link control field, and the enhanced multi-link control field may include an EMLSR mode field and an EMLMR mode field.

[0348] Furthermore, when the Non-AP MLD operates in the EMLMR mode, the multi-link operation update response frame includes an enhanced multi-link control field, and the enhanced multi-link control field may include at least one of an EMLMR link bitmap field or an EMLMR parameter update control field.

[0349] Furthermore, when the multi-link operation update response frame includes the third information field, the third information field may include at least one item of the first sub-information field or the second sub-information field.

[0350] In some embodiments, if the Non-AP MLD does not receive a multi-link operation update response frame within a switching timeout period, the Non-AP MLD may perform a link update for the enhanced multi-link mode.

[0351] If the Non-AP MLD works in the EMLSR mode, the Non-AP MLD performs EMLSR link update. If the Non-AP MLD works in the EMLMR mode, the Non-AP MLD performs EMLMR link update.

[0352] Optionally, when the multi-link operation update request frame includes a first information field, the first information field includes an enhanced multi-link control field, and the enhanced multi-link control field includes an EMLSR link bitmap field, the Non-AP MLD can perform an EMLSR link update according to the EMLSR link indicated by the EMLSR link bitmap field.

[0354] In some embodiments, if the Non-AP MLD receives a multi-link operation update response frame sent by the AP MLD within the conversion time, the Non-AP MLD may perform a link update for the enhanced multi-link mode.

[0355] If the Non-AP MLD works in the EMLSR mode, the Non-AP MLD performs EMLSR link update. If the Non-AP MLD works in the EMLMR mode, the Non-AP MLD performs EMLMR link update.

[0356] Optionally, when the multi-link operation update request frame includes a first information field, the first information field includes an enhanced multi-link control field, and the enhanced multi-link control field includes an EMLSR link bitmap field, the Non-AP MLD may perform an EMLSR link update according to the EMLSR link indicated by the EMLSR link bitmap field. Alternatively, when the multi-link operation update response frame includes a first information field, the first information field includes an enhanced multi-link control field, and the enhanced multi-link control field includes an EMLSR link bitmap field, the Non-AP MLD may perform an EMLSR link update according to the EMLSR link indicated by the EMLSR link bitmap field.

[0358] Step S44, the Non-AP MLD determines whether the multi-link operation update request frame and the multi-link operation update response frame include an enhanced multi-link mode parameter update control field.

[0359] The enhanced multi-link mode parameter update control field includes an EMLSR parameter update control field or an EMLMR parameter update control field.

[0360] That is, it is determined whether the multi-link operation update request frame and the multi-link operation update response frame include one of the EMLSR parameter update control field or the EMLMR parameter update control field.

[0361] As an example, when the Non-AP MLD operates in the EMLSR mode, the Non-AP MLD determines whether the multi-link operation update request frame and the multi-link operation update response frame include the EMLSR parameter update control field; when the Non-AP MLD operates in the EMLMR mode, the Non-AP MLD determines whether the multi-link operation update request frame and the multi-link operation update response frame include the EMLMR parameter update control field.

[0362] If the multi-link operation update request frame and the multi-link operation update response frame include an enhanced multi-link mode parameter update control field, step S46 is executed; otherwise, step S45 is executed.

[0363] That is, when the Non-AP MLD works in the EMLSR mode, if the multi-link operation update request frame and the multi-link operation update response frame include the EMLSR parameter update control field, step S46 is executed, otherwise step S45 is executed. When the Non-AP MLD works in the EMLMR mode, if the multi-link operation update request frame and the multi-link operation update response frame include the EMLMR parameter update control field, step S46 is executed, otherwise step S45 is executed.

[0364] Step S45: Non-AP MLD does not update parameters for the enhanced multi-link mode.

[0365] In some embodiments, when the Non-AP MLD operates in the EMLSR mode, the Non-AP MLD does not perform EMLSR parameter update. When the Non-AP MLD operates in the EMLMR mode, the Non-AP MLD does not perform EMLMR parameter update.

[0366] Step S46: the Non-AP MLD determines whether the enhanced multi-link mode update control field indicates to update parameters for the enhanced multi-link mode.

[0367] In some embodiments, if the multilink operation update request frame and the multilink operation update response frame include an EMLSR parameter update control field, the Non-AP MLD determines whether the EMLSR parameter update control field indicates an EMLSR parameter update through a third value.

[0368] If the multi-link operation update request frame and the multi-link operation update response frame include the EMLMR parameter update control field, the Non-AP MLD determines whether the EMLSR parameter update control field indicates to perform EMLSR parameter update through the fourth value.

[0369] If it is determined that the enhanced multi-link mode update control field is used to instruct parameter update for the enhanced multi-link mode, step S47 is executed; otherwise, step S45 is executed.

[0370] That is, when the Non-AP MLD works in the EMLSR mode, if the EMLSR parameter update control field in the multi-link operation update request frame and the multi-link operation update response frame indicates that the EMLSR parameter update is to be performed through the third value, then step S47 is executed, otherwise, step S45 is executed. When the Non-AP MLD works in the EMLMR mode, if the EMLMR parameter update control field in the multi-link operation update request frame and the multi-link operation update response frame indicates that the EMLMR parameter update is to be performed through the fourth value, then step S47 is executed, otherwise, step S45 is executed.

[0371] Step S47 , the Non-AP MLD determines whether the multi-link operation update request frame and the multi-link operation update response frame include an information field for indicating the enhanced multi-link mode parameters to be updated.

[0372] The information field for indicating the enhanced multi-link mode parameters to be updated includes a second information field for indicating the EMLSR parameters to be updated and a third information field for indicating the EMLMR parameters to be updated.

[0373] In some embodiments, when the Non-AP MLD operates in the EMLSR mode, the Non-AP MLD determines whether the multi-link operation update request frame and the multi-link operation update response frame include the second information field. If the second information field is included, step S49 is executed, otherwise step S48 is executed. When the Non-AP MLD operates in the EMLMR mode, the Non-AP MLD determines whether the multi-link operation update request frame and the multi-link operation update response frame include the third information field. If the third information field is included, step S49 is executed, otherwise step S48 is executed.

[0374] The second information field is used to indicate the EMLSR parameters to be updated, and the third information field is used to indicate the EMLMR parameters to be updated.

[0375] Step S48: Non-AP MLD updates the enhanced multi-link mode parameters carried in the basic multi-link element field.

[0376] In some embodiments, when Non-AP MLD operates in EMLSR mode, Non-AP MLD can update the EMLSR parameters carried in the Basic Multi-Link element field in the message frame during the association process between Non-AP MLD and AP MLD. When Non-AP MLD operates in EMLMR mode, Non-AP MLD can update the EMLMR parameters carried in the Basic Multi-Link element field in the message frame during the association process between Non-AP MLD and AP MLD.

[0377] Step S49: the Non-AP MLD updates the parameters of the enhanced multi-link mode according to the enhanced multi-link mode parameters to be updated indicated by the corresponding information field.

[0378] In some embodiments, when the Non-AP MLD works in the EMLSR mode, the Non-AP MLD may update the EMLSR parameters according to the EMLSR parameters to be updated indicated by the second information field.

[0379] Among them, when the second information field in the multi-link operation update request frame or the multi-link operation update response frame includes the third sub-information field, the Non-AP MLD can update the minimum MAC padding delay of the initial frame in the EMLSR mode indicated by the third sub-information field, such as updating the EMLSR Padding Delay parameter in the EMLSR mode.

[0380] Among them, when the second information field in the multi-link operation update request frame or the multi-link operation update response frame includes the fourth sub-information field, the Non-AP MLD can update the shortest delay for the EMLSR link to switch from the frame exchange state to the listening state in the EMLSR mode indicated by the fourth sub-information field, such as updating the EMLSR Transition Delay parameter in the EMLSR mode.

[0381] In some embodiments, when the Non-AP MLD works in the EMLMR mode, the Non-AP MLD may perform EMLMR parameter setting according to the EMLMR parameter indicated by the third information field.

[0382] Among them, when the third information field in the multi-link operation update request frame or the multi-link operation update response frame includes the first sub-information field, the Non-AP MLD can update the minimum MAC padding delay of the initial frame in the EMLMR mode indicated by the first sub-information field, such as updating the EMLMR Padding Delay parameter in the EMLMR mode.

[0383] Among them, when the third information field in the multi-link operation update request frame or the multi-link operation update response frame includes the second sub-information field, the Non-AP MLD can update the shortest delay for the EMLMR link to switch from the frame exchange state to the listening state in the EMLMR mode indicated by the second sub-information field, such as updating the EMLMR Transition Delay parameter in the EMLMR mode.

For example, any one of steps S41-S43 may be implemented as an independent embodiment, and steps S41-S49 may be implemented as an independent embodiment, but are not limited thereto.

[0385] Figure 5 FIG. 3 is a flow chart showing a communication method according to an embodiment of the present disclosure. Figure 5 As shown, the method is performed by the AP MLD, and the method includes:

[0386] Step S51: receiving a multi-link operation update request frame sent by a Non-AP MLD, wherein the multi-link operation update request frame includes a first information field, and the first information field is used to indicate state information of an enhanced multi-link mode of the Non-AP MLD.

[0387] In some embodiments, the enhanced multi-link mode comprises an enhanced multi-link single radio EMLSR mode or an enhanced multi-link multi-radio EMLMR mode.

[0388] In some embodiments, the multi-link operation update request frame is sent by the Non-AP MLD under a first condition, where the first condition includes at least one of the following:

[0389] When the Non-AP MLD works in enhanced multi-link mode, a new enabling communication link is added between the Non-AP MLD and the AP MLD;

[0390] When the Non-AP MLD operates in the enhanced multi-link mode, at least one enabled communication link of the Non-AP MLD in the enhanced multi-link mode fails.

[0391] As an example, when the Non-AP MLD operates in the EMLSR mode or the EMLMR mode, when a communication link is newly enabled between the Non-AP MLD and the AP MLD, the Non-AP MLD determines a multi-link operation update request frame.

[0392] As an example, in the case where the Non-AP MLD operates in the EMLSR mode, when at least one enabled EMLSR link of the Non-AP MLD in the EMLSR mode fails, the Non-AP MLD determines a multi-link operation update request frame.

[0393] As an example, in the case where the Non-AP MLD operates in the EMLMR mode, when at least one enabled EMLMR link of the Non-AP MLD in the EMLMR mode fails, the Non-AP MLD determines a multi-link operation update request frame.

[0394] In some embodiments, a multi-link operation update request (Multi-Link Operation UpdateRequest) frame includes a first information field, the first information field includes an enhanced multi-link control (EML Control) field, the enhanced multi-link control field includes an EMLSR mode (EMLSR Mode) field and an EMLMR mode (EMLMR Mode) field.

[0395] The EMLSR mode field indicates that the Non-AP MLD works in the EMLSR mode through a first value, and indicates that the Non-AP MLD does not work in the EMLSR mode through other values.

[0396] The first value may be 1, which is not limited here.

[0397] The EMLMR mode field indicates that the Non-AP MLD works in the EMLMR mode through the second value, and indicates that the Non-AP MLD does not work in the EMLMR mode through other values.

[0399] As an example, the first information domain includes an enhanced multi-link control domain, and the enhanced multi-link control domain includes an EMLSR mode domain and an EMLMR mode domain. When the identification value of the EMLSR mode domain is 1 and the identification value of the EMLMR mode domain is 0, it is used to indicate that the Non-AP MLD works in the EMLSR mode; when the identification value of the EMLSR mode domain is 0 and the identification value of the EMLMR mode domain is 1, it is used to indicate that the Non-AP MLD works in the EMLMR mode.

[0400] In some embodiments, when the Non-AP MLD operates in the EMLSR mode, the enhanced multi-link control field further includes an EMLSR link bitmap field; when the Non-AP MLD operates in the EMLMR mode, the enhanced multi-link control field further includes an EMLMR link bitmap field;

[0401] The EMLSR link bitmap field is used to indicate the EMLSR link when the Non-AP MLD works in the EMLSR mode, and the EMLMR link bitmap field is used to indicate the EMLMR link when the Non-AP MLD works in the EMLMR mode.

[0402] As an example, the Non-AP MLD determines a multi-link operation update request frame under a first condition, wherein the multi-link operation update request frame includes a first information field, the first information field includes an enhanced multi-link control field, and the enhanced multi-link control field includes an EMLSR mode field and an EMLMR mode field.

[0403] Among them, when the identification value of the EMLSR mode domain is 1 and the identification value of the EMLMR mode domain is 0, it is used to indicate that the Non-AP MLD works in the EMLSR mode. At this time, the enhanced multi-link control domain also includes an EMLSR link bitmap domain, and the EMLSR link bitmap domain is used to indicate the EMLSR link when the Non-AP MLD works in the EMLSR mode.

[0404] Among them, when the identification value of the EMLMR mode field is 0 and the identification value of the EMLMR mode field is 1, it is used to indicate that the Non-AP MLD works in the EMLMR mode. At this time, the enhanced multi-link control field also includes an EMLMR link bitmap field, and the EMLMR link bitmap field is used to indicate the EMLMR link when the Non-AP MLD works in the EMLMR mode.

[0405] In some embodiments, the enhanced multi-link control field further includes an EMLSR parameter update control (EMLSRParameter Update Control) field or an EMLMR parameter update control (EMLMR Parameter UpdateControl) field.

[0406] The EMLSR parameter update control field indicates the EMLSR parameter update through the third value, that is, indicates the update of the EMLSR parameters carried by the Basic Multi-Link element field in the process of associating the Non-AP MLD and the AP MLD.

[0407] The EMLMR parameter update control field indicates the EMLMR parameter update through the fourth value, that is, indicates the update of the EMLMR parameters carried by the Basic Multi-Link element field in the process of associating the Non-AP MLD and the AP MLD.

When the identification value of the EMLSR parameter update control field is a third value, it is used to indicate an EMLSR parameter update, that is, to request an EMLSR parameter update.

When the identification value of the EMLMR parameter update control field is a fourth value, it is used to indicate that an EMLMR parameter update is to be performed, that is, to request an EMLMR parameter update.

[0411] In some embodiments, when the enhanced multi-link control domain includes an EMLSR parameter update control (EMLSRParameter Update Control) domain, when the EMLSR parameter update control domain is used to indicate an EMLSR parameter update, the multi-link operation update request frame also includes a second information domain, and the second information domain is used to indicate the EMLSR parameters to be updated.

[0412] In the case where the enhanced multi-link control field includes an EMLMR parameter update control (EMLMR Parameter UpdateControl) field, when the EMLMR parameter update control field is used to indicate an EMLMR parameter update, the multi-link operation update request frame also includes a third information field, and the third information field is used to indicate the EMLMR parameters to be updated.

[0413] Optionally, the EMLSR parameter to be updated includes at least one of the following:

[0414] Minimum medium access control (MAC) padding delay for initial frames in EMLSR mode;

[0415] The shortest delay for the EMLSR link to switch from the frame exchange state to the listening state in EMLSR mode.
