[0003] To meet the various requirements of UHR, at least one operating mode supported by the communication equipment is proposed. Therefore, a mechanism is needed to manage these operating modes. Summary of the Invention

[0004] This disclosure provides a communication method, communication device, and communication system to provide a mechanism for managing the operating modes supported by the communication device, thereby improving the efficiency of updating the mode status and operating parameters of each operating mode and reducing signaling overhead.

[0005] In a first aspect, embodiments of this disclosure provide a communication method executed by an AP MLD, the method comprising:

[0006] A first radio frame is determined; wherein the first radio frame is used to: respond to a second radio frame sent by a non-AP MLD, or to instruct a first update operation for at least one operating mode of an affiliated AP of the AP MLD under at least one first link;

[0007] The second radio frame is used to request: a second update operation for at least one operating mode of the non-AP STA associated with the non-AP MLD under at least one second link; the update operation includes at least one of a mode state update operation and an operating parameter update operation; the first link and the second link are both links established between the non-AP MID and the AP MID;

[0010] Receive a first radio frame sent by the AP MLD; wherein the first radio frame is used to: respond to a second radio frame sent by the non-AP MLD, or to instruct a first update operation for at least one operating mode of the AP MLD's affiliated AP under at least one first link;

[0084] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0085] The following embodiments of this disclosure can be applied to Figure 1 The communication system 100 shown, or a part thereof, but not limited to it. Figure 1 The entities shown are illustrative; a communication system may include... Figure 1 All or part of the main body, or may include Figure 1 Other entities besides the main body, the number and form of each entity are arbitrary, each entity can be physical or virtual, the connection relationship between the entities is illustrative, the entities can be unconnected or connected, and the connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0086] The embodiments disclosed herein can be applied to Wireless Local Area Networks (WLANs), such as LANs using the 802.11 series of protocols. In a WLAN, a Basic Service Set (BSS) is a fundamental component. An BSS network consists of site devices with some association within a specific coverage area. One type of association is where sites communicate directly with each other in a self-organizing network; this is called an Independent Basic Service Set (IBSS). Another more common scenario is that in a BSS network, there is only one central site dedicated to managing the BSS, called an Access Point (AP) device, while other sites in the BSS network that are not APs are called terminals, also known as non-AP STAs. APs and non-AP STAs are collectively referred to as STAs. When describing STAs, it is not necessary to distinguish between APs and non-AP STAs. Within the same BSS network, due to distance, transmission power, etc., a STA cannot detect other STAs that are far away; they are each other's hidden nodes.

[0087] In some embodiments, different operation modes (also known as operation mechanisms) are introduced in the UHR to suit different needs. Specifically, as some examples, the operation modes introduced under different needs are briefly introduced below.

[0088] In some embodiments, to further improve channel access or frequency utilization efficiency and transmission efficiency in broadband systems, a Non-Primary Channel Access (NPCA) mechanism is introduced in the UHR. This mechanism prevents communication devices from being unable to communicate on other bandwidths when the primary 20MHz channel (i.e., the main channel with a bandwidth of 20MHz) is detected as busy, thus avoiding wasted bandwidth resources. Based on the NPCA mechanism, when a communication device detects that the primary 20MHz channel is busy due to OBSS activity, the communication device can switch to a non-primary channel and perform channel contention access and frame switching on the non-primary channel to improve the throughput of the communication system and meet the latency requirements of low-latency service transmission.

[0089] In some embodiments, to further improve spectrum utilization efficiency, transmission efficiency and reduce transmission interference, the UHR introduces a Dynamic Subchannel Operation (DSO) mechanism and a Dynamic Band Expansion (DBE) mechanism.

[0090] The DSO mechanism primarily addresses the bandwidth mismatch issue between STAs and APs. Specifically, compared to the bandwidth supported by the AP, most STAs support narrower bandwidths. When an AP communicates with a STA supporting a narrower bandwidth, its bandwidth capacity is not fully utilized, leading to wasted bandwidth resources. For example, in multi-user transmission scenarios, such as downlink multi-user physical layer protocol data unit (DL MU PPDU, where DL stands for downlink, MU for multi-user, and PPDU for Physical Layer Protocol Data Unit) transmission or uplink multi-user triggered physical layer protocol data unit (UL MU TB PPDU) transmission, the resource units (RUs) allocated by the AP to the STA are very limited. This limited RU allocation severely impacts the transmission efficiency between the AP and STA. With DSO support from both the AP and STA, when the AP allocates RUs to the STA, it can allocate RUs within the BSS single bandwidth but outside the STA's supported bandwidth. This allows the AP to fully utilize spectrum resources, improve transmission efficiency, and reduce transmission interference between multiple users.

[0091] The DBE mechanism can further expand the operating bandwidth supported by the AP, maximizing channel bandwidth and improving system throughput. Through a multi-access point coordination mechanism, control signaling enables the exchange of channel usage and load information between access point devices. The DBE mechanism identifies bandwidth expansion opportunities and adjusts bandwidth for eligible site devices, achieving seamless and low-interference bandwidth expansion. In some embodiments, the DBE mechanism is particularly important for dense AP deployments and enterprise network deployments.

[0092] In some embodiments, with the development of wireless communication technology, terminal devices are becoming increasingly integrated. A single terminal device often supports multiple wireless communication protocols, integrates multiple wireless communication modules, or simultaneously accesses multiple wireless networks. For example, a terminal device may simultaneously support Bluetooth (BT), New Radio (NR), Long Time Evolution (LTE), and Ultra Wide Band (UWB) technologies. When the communication frequency bands of different communication systems (i.e., the frequency bands supported by the terminal device under different communication technologies) are adjacent, the transmitting operation of the terminal device in one communication system may interfere with its receiving operation in another communication system. Especially when multiple wireless communication modules coexist, the physical spacing between the radio frequency (RF) modules of each communication module is small. When different communication modules are working simultaneously, communication between the communication systems interferes with each other, affecting the transmission and reception of each communication module. For Wi-Fi devices, this in-device coexistence (IDC) activity can lead to the loss or even interruption of Wi-Fi service transmission. To address this, the UHR proposes the DUO (Dynamic Unavailability Operation) mechanism. Specifically, when there is mutual interference between Wi-Fi and non-Wi-Fi communication systems, communication devices can be configured to prevent the transmission of Wi-Fi services when communicating through a non-Wi-Fi communication system, meaning that the device is unavailable within the Wi-Fi communication system.

[0093] In some embodiments, to further enhance the power-saving mechanism, a Dynamic Power Save (DPS) mode is proposed in the UHR. When the Mobile AP (Mobile Access Point) or STA enables Dynamic Power Save mode, the communication capability of the Mobile AP or STA in Low Capability (LC) mode is limited. If the peer device needs to exchange frames with it, the peer device needs to send an initial control frame to switch it from the low capability mode to a higher capability mode, thereby realizing frame exchange with the peer device. In this way, in the DPS mechanism, device-level power consumption is reduced through dynamic changes in operating mode.

[0094] In some embodiments, to further reduce the transmission latency of low-latency services, in the UHR, the STA can provide a Low Latency Indication (LLI) to its associated AP. The LLI may include, but is not limited to, the type of low-latency service and latency requirements.

[0095] Referring to the different mechanisms mentioned above, and considering the potential introduction of even more mechanisms as Wi-Fi technology advances, the various mechanisms (features) introduced into the UHR, while offering numerous benefits such as reduced latency, improved spectrum efficiency, and reduced energy consumption, also increase signaling overhead. For example, for non-AP MLDs, the enabling and disabling of various operating modes, as well as the indication of operating parameter updates when communication capabilities are limited in IDC scenarios, require signaling standardization to maximize the efficiency of operating mode indications and minimize signaling overhead. Furthermore, how the AP MLD responds to operating mode change and operating parameter update requests from the non-AP MLD directly impacts the subsequent operating modes and communication of the non-AP MLD device. Additionally, when the AP MLD needs to update the mode status or operating parameters of certain operating modes, how to promptly inform its associated devices of the update information also requires signaling standardization. For example, in DBE mode, the operating bandwidth may be adjusted in real time according to the communication environment of neighboring APs; in DBE mode, the NPCA Primary channel can be extended to other sub-channels; in DSO mode or NPCA mode, the AP's handover delay and other operating parameters need to be adjusted.

[0096] Therefore, it is necessary to propose an operation parameter update method, process, and device to improve the negotiation process for updating operation parameters between non-AP MLD and AP MLD to enable, disable, and restrict operation modes, as well as the instruction process for updating operation parameters at the AP MLD end.

[0097] Figure 2 This is one of the interactive schematic diagrams of a communication method according to an embodiment of this disclosure. For example... Figure 2 As shown, the above method includes:

[0098] Step 201, the AP MLD determines a first radio frame; wherein the first radio frame is used to: respond to a second radio frame sent by the non-AP MLD, or to indicate a first update operation for at least one operating mode of the AP associated with the AP MLD under at least one first link;

[0099] The second radio frame is used to request: a second update operation for at least one operating mode of the non-AP STA of the non-AP MLD under at least one second link; the update operation includes at least one of a mode state update operation and an operating parameter update operation; the first link and the second link are both links established between the non-AP MID and the AP MID.

[0100] Step 202: The AP MLD transmits the first radio frame. Correspondingly, the non-AP MLD receives the first radio frame transmitted by the AP MLD.

[0101] Optionally, multiple links can be established between the non-AP MLD and the AP MLD. Under each link, the AP operating under that link and attached to the non-AP MLD can support at least one of the above operating modes, and the non-AP STA operating under that link and attached to the AP MLD can support at least one of the above operating modes. The operating modes supported by the AP and the non-AP STA corresponding to that link can be the same or different; this disclosure does not impose any limitations on this.

[0102] As an example, four links are established between the non-AP MLD and the AP MLD: link1, link2, link3, and link4. Under link2, the non-AP STA2 attached to the non-AP MLD supports DPS Mode, NPCA Mode, DUO Mode, DSO Mode, DBE Mode, LLI Mode, and AOM Mode (Adaptive Operating Mode). The AP2 attached to the AP MLD supports NPCA Mode, DSO Mode, and DBE Mode.

[0103] Optionally, in some embodiments, the mode state update operation includes enabling or disabling the operating mode;

[0104] The operation parameter update operation includes updating at least one operation parameter of the operation mode.

[0105] Optionally, for a certain operating mode, when performing a mode state update operation on the operating mode, the operating mode can be updated from the enabled state to the disabled state, that is, the operating mode is disabled or turned off, meaning that non-AP STAs cannot communicate in this operating mode; or the operating mode can be updated from the disabled state to the enabled state, that is, the operating mode is enabled or turned on, meaning that non-AP STAs can communicate in this operating mode.

[0106] Optionally, for a certain operating mode, the operating mode may include one or more operating parameters, and at least one of the operating parameters may be updated.

[0107] It is understandable that when at least one operating parameter of an operating mode is updated, that is, when the operating mode is enabled, the corresponding operating parameter is updated.

[0108] As an example, when updating at least one operating mode of the non-AP STA attached to the non-AP MLD under a certain link, the mode state of the STA operating under the link and attached to the non-AP MLD can be updated, the operating parameters when the STA's operating mode 2 is enabled can be updated, and the STA's operating mode 3 can be enabled at the same time, and the operating parameters when the STA's operating mode 3 is enabled can be updated.

[0109] Step 202 may include two scenarios: Scenario 1: In response to the second radio frame sent by the non-AP MLD, the AP MLD sends a first radio frame to the non-AP MLD, whereby the first radio frame is used to respond to the second radio frame sent by the non-AP MLD; or Scenario 2: The AP MLD sends a first radio frame to the non-AP MLD, whereby the first radio frame is used to instruct a first update operation for at least one operating mode of the AP affiliated with the AP MLD under at least one first link. Each scenario is described below:

[0110] (a) Method 1:

[0111] Optionally, when any affiliated non-AP STA of a non-AP MLD needs to update the mode state of any supported operating mode or the operating parameters when any operating mode is enabled, under its operating link (i.e., the first link), it can request the corresponding operating mode update operation by sending a second radio frame to the AP MLD. That is, the second radio frame requests that at least one operating mode of the affiliated non-AP STA of the non-AP MLD be updated under at least one of the first links established between the non-AP MLD and the AP MLD.

[0112] Optionally, the second radio frame may include, but is not limited to, a UHR Link Reconfiguration Request frame.

[0113] Optionally, the second radio frame includes multiple fields, and the fields in the second radio frame and their corresponding field sequence numbers in the second radio frame can be found in Table 1.

[0114] Table 1:

[0115]

[0116] Referring to Table 1, the second radio frame may include the following fields in sequence: Category field, Protected UHR Action field, Dialog Token field (for distinction, the Dialog Token field in the second radio frame can be referred to as the "third dialogue token field"), Type field (for distinction, the Type field in the second radio frame can be referred to as the "third type field"), and third element.

[0117] The third element can be a Reconfiguration Multi-Link element or a variant of a Multi-Link element. Optionally, the third element can carry operation mode update information related to the operation mode update operation, namely, the operation mode that the second radio frame requests to enable or disable, the operation parameters of the enabled operation mode, and the link to which the update operation requested by the second radio frame applies.

[0118] It should be understood that, in addition to the fields mentioned above, the second radio frame may also include other fields, which will not be listed here.

[0119] Optionally, in the second radio frame, different meanings can be indicated when the value of the third type field is different.

[0120] Optionally, in the second radio frame, the (Protected)UHR Action field and the Type field can identify the frame type and function of the second radio frame.

[0121] As an example, in the second radio frame, if the (Protected)UHR Action field is set to the second parameter value, it can be identified that the second radio frame is a UHR link reconfiguration request frame; if the (Protected)UHRAction field is set to the second parameter value and the third type field is set to the third parameter value (e.g., 3), it can be identified that the second radio frame (UHR Link Reconfiguration Request frame) is used to perform an operation mode update operation, that is, the frame type of the second radio frame is: requesting UHR operation mode enable / disable or operation mode update.

[0122] Optionally, in the second radio frame, the third session token field can carry the session token of the current session. That is, the session token carried by the third session token field can uniquely identify the current session, that is, the session formed by the non-AP MLD and AP MLD updating the mode state or operation parameters of the operation mode.

[0123] Optionally, if the second radio frame includes a UHR Link Reconfiguration Request frame, the first radio frame may include a UHR Link Reconfiguration Notify frame.

[0124] Optionally, upon receiving a second radio frame from a non-AP MLD, the AP MLD can respond to the second radio frame. Specifically, in response to the second radio frame, the AP MLD sends a first radio frame to the non-AP MLD. The first radio frame is used to respond to the second radio frame sent by the non-AP MLD, and it can be a response frame to the second radio frame.

[0125] For example, the first radio frame may indicate whether the AP MLD is ready to communicate with the non-AP MLD (operating in the operating mode following the update operation indicated by the second radio frame), or the first radio frame may indicate whether the AP MLD accepts or does not accept the request information initiated by the non-AP MLD via the second radio frame.

[0126] Optionally, when the AP MLD receives the second radio frame sent by the non-AP MLD, it may choose not to respond to the second radio frame. In this case, it may be assumed that the AP MLD is ready to communicate with the non-AP MLD (operating in the operation mode after the update operation indicated by the second radio frame), or the AP MLD may accept the request information initiated by the non-AP MLD through the second radio frame.

[0127] Optionally, the non-AP MLD may execute the update operation requested by the second radio frame if it receives the first radio frame sent by the AP MLD and the first radio frame indicates that the AP MLD is ready to communicate with the non-AP MLD (operating in the operation mode after the update operation indicated by the second radio frame), or if the AP MLD accepts the request information initiated by the non-AP MLD through the second radio frame; or, if the non-AP MLD does not receive the first radio frame within a first time period, it may assume that the AP MLD is ready to communicate with the non-AP MLD (operating in the operation mode after the update operation indicated by the second radio frame), or the AP MLD accepts the request information initiated by the non-AP MLD through the second radio frame and executes the update operation requested by the second radio frame.

[0128] Optionally, the first duration can be a timeout duration set according to actual communication needs. In this embodiment of the disclosure, the specific time interval indicated by the timeout duration is not limited.

[0129] Furthermore, when any of the affiliated APs of the AP MLD needs to update the mode state of any of its supported operating modes or update the operating parameters when any of its operating modes are enabled on its working link (i.e., the second link), the AP MLD, in response to the second radio frame sent by the non-AP MLD via the first radio frame, can also instruct its affiliated APs to update their corresponding operating modes via the first radio frame.

[0130] (II) Method Two:

[0131] Optionally, when any of the affiliated APs of the AP MLD needs to update the mode state of any supported operating mode or update the operating parameters when any operating mode is enabled under its operating link (i.e., the second link), it can send a first radio frame to the non-AP MLD to instruct the corresponding operating mode update operation. That is, the first radio frame is used to instruct: to perform a first update operation on at least one operating mode of the affiliated APs of the AP MLD under at least one first link.

[0132] Optionally, the first radio frame may include, but is not limited to, an unsolicited UHR Link Reconfiguration Notify frame, a UHR Link Reconfiguration Notify frame, or a response frame to a request frame. For example, when responding to an association request frame initiated by a non-AP MLD, the response frame may indicate: establishing an association with the non-AP MLD, and performing a first update operation on at least one operating mode of the APs affiliated with the AP MLD under at least one first link.

[0133] Optionally, in some embodiments, the AP MLD actively sends the first radio frame. For example, the AP MLD may send the first radio frame to the non-AP MLD without receiving an operation mode update request (i.e., the second radio frame) initiated by the non-AP MLD.

[0134] Optionally, the first link may be the same as or different from the second link, and this disclosure does not impose any restrictions on this.

[0135] As an example, continuing with the previous example, four links are established between the non-AP MLD and the AP MLD: link1, link2, link3, and link4. Under link2, non-APSTA2, attached to the non-AP MLD, supports DPS Mode, NPCA Mode, DUO Mode, DSO Mode, DBE Mode, LLI Mode, and AOM Mode. AP2, attached to the AP MLD, supports NPCA Mode, DSO Mode, and DBE Mode. Under link3, non-AP STA3, attached to the non-AP MLD, supports DPS Mode, NPCA Mode, DSO Mode, DBE Mode, LLI Mode, and AOM Mode. AP3, attached to the AP MLD, supports DSO Mode, NPCA Mode, and DBE Mode. If the second radio frame requests that DSO Mode be enabled for non-AP STA2 under link2 and DBE Mode be disabled for non-AP STA3 under link3, the AP MLD can send the first radio frame to the non-AP MLD, indicating that while the AP MLD accepts the request information of the second radio frame, it should also indicate the update information of the operation parameters of NPCA Mode under link3.

[0136] In this embodiment of the disclosure, when the AP MLD and non-AP MLD support multiple operating modes, when the AP MLD or non-AP MLD needs to update the mode state of the operating mode, update the operating parameters of the operating mode, or update both the mode state and operating parameters of the operating mode simultaneously, the AP MLD can improve the negotiation process for updating the mode state or operating parameters of multiple operating modes between the non-AP MLD and the AP MLD by responding to the second radio frame or by directly indicating through the first radio frame, as well as the indication process for updating operating parameters on the AP MLD side, thereby improving the efficiency and reliability of updating the mode state and operating parameters of the operating modes between multi-link devices.

[0137] Figure 3 This is a second interactive schematic diagram of a communication method according to an embodiment of this disclosure. For example... Figure 3 As shown, the above method includes:

[0138] Step 301, the AP MLD determines the first radio frame; wherein the first radio frame is used to: respond to the second radio frame sent by the non-AP MLD;

[0139] The second radio frame is used to request: a second update operation for at least one operating mode of the non-AP STA of the non-AP MLD under at least one second link; the update operation includes at least one of a mode state update operation and an operating parameter update operation; the first link is a link established between the non-AP MID and the AP MID.

[0140] Optionally, multiple links can be established between the non-AP MLD and the AP MLD. Under each link, the AP operating under that link and attached to the non-AP MLD can support at least one of the above operating modes, and the non-AP STA operating under that link and attached to the AP MLD can support at least one of the above operating modes. The operating modes supported by the AP and the non-AP STA corresponding to that link can be the same or different; this disclosure does not impose any limitations on this.

[0141] As an example, four links are established between the non-AP MLD and the AP MLD: link1, link2, link3, and link4. Under link2, the non-AP STA2 attached to the non-AP MLD supports DPS Mode, NPCA Mode, DUO Mode, DSO Mode, DBE Mode, LLI Mode, and AOM Mode (Adaptive Operating Mode). The AP2 attached to the AP MLD supports NPCA Mode, DSO Mode, and DBE Mode.

[0142] Optionally, in some embodiments, the mode state update operation includes enabling or disabling the operating mode;

[0143] The operation parameter update operation includes updating at least one operation parameter of the operation mode.

[0144] Optionally, for a certain operating mode, when performing a mode state update operation on the operating mode, the operating mode can be updated from the enabled state to the disabled state, that is, the operating mode is disabled or turned off, meaning that non-AP STAs cannot communicate in this operating mode; or the operating mode can be updated from the disabled state to the enabled state, that is, the operating mode is enabled or turned on, meaning that non-AP STAs can communicate in this operating mode.

[0145] Optionally, for a certain operating mode, the operating mode may include one or more operating parameters, and at least one of the operating parameters may be updated.

[0146] It is understandable that when at least one operating parameter of an operating mode is updated, that is, when the operating mode is enabled, the corresponding operating parameter is updated.

[0147] As an example, when updating at least one operating mode of the non-AP STA attached to the non-AP MLD under a certain link, the mode state of the STA operating under the link and attached to the non-AP MLD can be updated, the operating parameters when the STA's operating mode 2 is enabled can be updated, and the STA's operating mode 3 can be enabled at the same time, and the operating parameters when the STA's operating mode 3 is enabled can be updated.

[0148] Optionally, when any affiliated non-AP STA of a non-AP MLD needs to update the mode state of any supported operating mode or the operating parameters when any operating mode is enabled, under its operating link (i.e., the first link), it can request the corresponding operating mode update operation by sending a second radio frame to the AP MLD. That is, the second radio frame requests that at least one operating mode of the affiliated non-AP STA of the non-AP MLD be updated under at least one of the first links established between the non-AP MLD and the AP MLD.

[0149] Optionally, the second radio frame may include, but is not limited to, a UHR Link Reconfiguration Request frame.

[0150] Optionally, upon receiving a second radio frame from a non-AP MLD, the AP MLD can respond to the second radio frame. That is, in response to the second radio frame, the first radio frame is determined.

[0151] Optionally, in some embodiments, the first wireless frame indicates:

[0152] Respond to the second update operation requested by the second radio frame; or,

[0153] Responding to the second update operation requested by the second radio frame, and performing a first update operation on at least one operating mode of the AP MLD's affiliated AP under the at least one first link.

[0154] Optionally, in some embodiments, it may be configured such that, in case A, the first radio frame indicates that the AP MLD responds to the update operation requested by the second radio frame; and in case B, the first radio frame indicates that the AP MLD responds to the update operation requested by the second radio frame, and performs a first update operation on at least one operating mode of the AP MLD's affiliated AP under at least one of the aforementioned first links.

[0155] Optionally, in case A, the AP MLD responds to the second update operation requested by the second radio frame, meaning the AP MLD is ready to communicate with the non-AP MLD operating after the update operation indicated by the second radio frame; or, the AP MLD accepts the update operation requested by the second radio frame, meaning the AP MLD is ready to communicate with the non-AP STAs (operating under each of the first links indicated by the second radio frame and attached to the non-AP MLD); or, the AP MLD accepts the update operation requested by the attached non-AP STAs under each of the first links. Accordingly, the attached APs under each of the first links can enter a ready state corresponding to the update operation.

[0156] Optionally, in case B, while the AP MLD responds to the second radio frame, it can also perform a first update operation on at least one operating mode of the AP MLD's affiliated APs under at least one of the first links. That is, after receiving the second radio frame sent by the non-AP MLD, the AP MLD is ready to communicate with the non-AP MLD operating after the update operation indicated by the second radio frame, and any affiliated AP of the AP MLD needs to update the mode state of any of its supported operating modes or update the operating parameters when any of its operating modes are enabled under its operating link (i.e., the second link).

[0157] Optionally, if the second radio frame includes a UHR Link Reconfiguration Request frame, the first radio frame may include a UHR Link Reconfiguration Notify frame.

[0158] Optionally, the first link may be the same as or different from the second link, and this disclosure does not impose any restrictions on this.

[0159] As an example, continuing with the previous example, four links are established between the non-AP MLD and the AP MLD: link1, link2, link3, and link4. Under link2, non-APSTA2, attached to the non-AP MLD, supports DPS Mode, NPCA Mode, DUO Mode, DSO Mode, DBE Mode, LLI Mode, and AOM Mode. AP2, attached to the AP MLD, supports NPCA Mode, DSO Mode, and DBE Mode. Under link3, non-AP STA3, attached to the non-AP MLD, supports DPS Mode, NPCA Mode, DSO Mode, DBE Mode, LLI Mode, and AOM Mode. AP3, attached to the AP MLD, supports DSO Mode, NPCA Mode, and DBE Mode. If the second radio frame requests that DSO Mode be enabled for non-AP STA2 under link2 and DBE Mode be disabled for non-AP STA3 under link3, the AP MLD can send the first radio frame to the non-AP MLD, indicating that while the AP MLD accepts the request information of the second radio frame, it should also indicate the update information of the operation parameters of NPCA Mode under link3.

[0160] In each case, the specific settings for the first wireless frame are as follows:

[0161] Scenario A: The first radio frame indicates: respond to the update operation requested by the second radio frame.

[0162] Optionally, in some embodiments, the AP MLD is ready to communicate with the non-AP MLD corresponding to the second update operation requested by the second radio frame.

[0163] As described above, the AP MLD is ready to communicate with the non-APMLD corresponding to the second update operation requested by the second radio frame, that is, the APs under the AP MLD on each first link enter the preparation state corresponding to the second update operation requested by the second radio frame.

[0164] As an example, continuing with the above example, four links are established between the non-AP MLD and the AP MLD: link1, link2, link3, and link4. Under link2, non-APSTA2, attached to the non-AP MLD, supports DPS Mode, NPCA Mode, DUO Mode, DSO Mode, DBE Mode, LLI Mode, and AOM Mode. AP2, attached to the AP MLD, supports NPCA Mode, DSO Mode, and DBE Mode. Therefore, if the second radio frame requests enabling DSO Mode for non-AP STA2 under link2, and the AP MLD accepts the request, the AP MLD can send a first radio frame to the non-AP MLD, indicating that under link2, AP2, attached to the AP MLD, enters the ready state corresponding to enabling DSO Mode; that is, AP2 is ready to communicate with non-AP STA2 in DSO Mode.

[0165] Optionally, in some embodiments, the first wireless frame includes at least one of the following:

[0166] The first action type field identifies that the first radio frame indicates a response to an update operation for a non-AP MLD request;

[0167] The first type field is the same as the type field in the second radio frame;

[0168] The first dialogue token field is the same as the dialogue token field in the second radio frame.

[0169] Optionally, in some embodiments, when the first radio frame indicates a response to the second update operation requested by the second radio frame, the indication can be made implicitly or explicitly.

[0170] In the implicit indication method, when the AP MLD responds to the second radio frame, it can indirectly indicate that the AP MLD is responding to the second radio frame by carrying a first type field and a first session token field in the first radio frame, and setting the first type field to be the same as the third type field in the second radio frame, and the first session token field to be the same as the second session token field in the second radio frame.

[0171] In the explicit indication method, when the AP MLD responds to the second radio frame, it can carry a first action type field in the first radio frame to indicate that the first radio frame indicates that it is responding to the second update operation requested by the non-AP MLD. This directly indicates that the AP MLD responds to the second radio frame by sending the first radio frame to the non-AP MLD, and that the AP MLD is ready to communicate with the non-AP MLD corresponding to the second update operation requested by the second radio frame.

[0172] Optionally, the first action type field can be a Protected UHR Action field. When the Protected UHR Action field is set to the fourth parameter value, it can be identified that the first radio frame is a UHR Link Reconfiguration Notify frame.

[0173] Case B: The first radio frame indicates: responding to the second update operation requested by the second radio frame; and performing a first update operation on at least one operating mode of the AP MLD's affiliated AP under at least one first link.

[0174] Optionally, in some embodiments, the first wireless frame includes at least one of the following:

[0175] The first action type field identifies that the first radio frame indicates a response to an update operation for a non-AP MLD request;

[0176] The first type field is the same as the type field in the second radio frame;

[0177] The first dialogue token field is the same as the dialogue token field in the second radio frame.

[0178] Optionally, in some embodiments, when the first radio frame indicates a response to the second update operation requested by the second radio frame, the indication can be made implicitly or explicitly.

[0179] In the implicit indication method, when the AP MLD responds to the second radio frame, it can indirectly indicate that the AP MLD is responding to the second radio frame by carrying a first type field and a first session token field in the first radio frame, and setting the first type field to be the same as the third type field in the second radio frame, and the first session token field to be the same as the second session token field in the second radio frame.

[0180] In the explicit indication method, when the AP MLD responds to the second radio frame, it can carry a first action type field in the first radio frame to indicate that the first radio frame indicates that it is responding to the second update operation requested by the non-AP MLD. This directly indicates that the AP MLD responds to the second radio frame by sending the first radio frame to the non-AP MLD, and that the AP MLD is ready to communicate with the non-AP MLD corresponding to the second update operation requested by the second radio frame.

[0181] Optionally, the first action type field can be a Protected UHR Action field. When the Protected UHR Action field is set to the fourth parameter value, it can be identified that the first radio frame is a UHR Link Reconfiguration Notify frame.

[0182] Optionally, in case B, the first action type field can also indicate that the first radio frame announces an update operation on the operating mode of the AP attached to the AP MLD, thus implicitly indicating that the first radio frame should respond to an update operation requested by the non-AP MLD.

[0183] Optionally, in some embodiments, when the first radio frame is used to indicate a first update operation for at least one operating mode of the AP MLD's affiliated AP under at least one first link, the first radio frame includes at least one of the following:

[0184] The link information of the link used in the first update operation;

[0185] The mode status information of the operation mode of the auxiliary AP under the link of the first update operation application;

[0186] The operation parameter information of the auxiliary AP's operation mode under the first update operation application link.

[0187] Optionally, referring to the information carried by the third element in the second radio frame, the first radio frame may carry at least one of the following: link information of the link of the first update operation application; mode status information of the operation mode of the auxiliary AP of the AP MLD under the link of the first update operation application; and operation parameter information of the operation mode of the auxiliary AP of the AP MLD under the link of the first update operation application.

[0188] Optionally, the above information can be carried in the first wireless frame through the frame configuration provided by configuration one and / or configuration two.

[0189] (I) Configuration 1

[0190] Optionally, in some embodiments, the first wireless frame includes a first element, which includes at least one of the following:

[0191] The first identifier field identifies the operation mode for updating the mode state and / or updating the operation parameters.

[0192] The second identifier field, each of the second identifier fields corresponds to an operation mode identified by the first identifier field; the second identifier field identifies the operation parameters to be updated according to the corresponding operation mode.

[0193] The third identifier field indicates whether the first identifier field exists in the first element.

[0194] Optionally, the first element may include a Reconfiguration Multi-Link element or a variant of the Multi-Link element.

[0195] Optionally, in the first radio frame, the first identification field may include an Operation Parameter UpdateMode Bitmap field, the second identification field may include a UHR Modes Parameters field, and the third identification field may include an Operation Parameter Update Present identifier.

[0196] Optionally, in the first radio frame, the first element may include, but is not limited to, at least one of the Operation Parameter Update Mode Bitmap field, the UHR Modes Parameters field, and the Presence Bitmap subfield. The Presence Bitmap subfield may include an Operation Parameter Update Present identifier.

[0197] Optionally, in the first radio frame, the Operation Parameter Update Present identifier can be in the Presence Bitmap subfield of the first element, and the Operation Parameter Update Present identifier can occupy one bit in the Presence Bitmap subfield. By setting this bit to different parameter values, it can be used to identify whether there is an Operation Parameter Update Mode Bitmap field in the first element, that is, whether there is a first identifier field in the first element.

[0198] Optionally, if the Operation Parameter Update Present identifier is set to "0", it indicates that the Operation Parameter Update Mode Bitmap field does not exist in the first element. For example, the first element only includes the Operation Parameter Update Mode Bitmap field.

[0199] Optionally, when the Operation Parameter Update Present identifier is set to "1", it indicates that the first element contains an Operation Parameter Update Mode Bitmap field. For example, the first element includes an Operation Parameter Update Mode Bitmap field and a Presence Bitmap subfield, and the Presence Bitmap subfield includes the Operation Parameter Update Present identifier; or, the first element includes an Operation Parameter Update Mode Bitmap field, a UHR Modes Parameters field, and a Presence Bitmap subfield, and the Presence Bitmap subfield includes the Operation Parameter Update Present identifier.

[0200] Optionally, in the first radio frame, the Operation Parameter Update Mode Bitmap field may include at least one byte.

[0201] Taking the Operation Parameter Update Mode Bitmap field, which consists of one byte (eight bits B0-B7), as an example, if the AP MLD's associated AP supports NPCA Mode, DBE Mode, and DSO Mode, bits B0-B2 of B0-B7 can be set to correspond to NPCA Mode, DBE Mode, and DSO Mode, respectively. When any bit in B0-B2 is set to "1", it indicates that the AP MLD's mode state and / or operation parameters in the corresponding operation mode should be updated. When any bit in B0-B2 is set to "0", it indicates that the AP MLD's mode state and / or operation parameters should not be updated in the corresponding operation mode. In other words, the AP MLD accepts mode state update requests and / or operation parameter update requests from non-AP MLDs in the corresponding operation mode.

[0202] Optionally, in the first radio frame, the UHR Modes Parameters field may carry at least one operation parameter corresponding to the operation mode in which the corresponding bit in the OperationParameter Update Mode Bitmap field is set to "1", i.e., the operation parameter for updating.

[0203] Optionally, corresponding to NPCA Mode, the operation parameter field in this mode, namely the NPCA operation parameter field, includes, but is not limited to, at least one of the following: NPCA Primary Channel, NPCA Minimum Duration Threshold, NPCA Switching Delay, and NPCA Switch Back Delay. The NPCA Primary Channel may include, but is not limited to, the bandwidth information of the NPCA Primary; the NPCA Minimum Duration Threshold is the minimum duration required for NPCA operation; the NPCA Switching Delay is the duration required to perform the NPCA operation; and the NPCA Switch Back Delay is the duration required to switch from the NPCA Primary Channel to the BSS Primary information.

[0204] Optionally, corresponding to DBE Mode, the operation parameter field of this operation mode is the DBE operation parameter field, which includes but is not limited to DBE bandwidth, which is the extended channel bandwidth.

[0205] Optionally, corresponding to DSO Mode, the operation parameter field of this operation mode, namely the DSO operation parameter field, includes, but is not limited to, one or more of DSO Padding Delay and DSO Switch Back Delay.

[0206] Optionally, in some embodiments, the first element further includes a first field and at least one second field, wherein,

[0207] When the second identifier field is carried in the first field, the operating parameters identified by the second identifier field are applied to all associated APs of the AP MLD;

[0208] When the second identifier field is carried in the second field, the operation parameters identified by the second identifier field are applied to the affiliated AP under the link corresponding to the second field.

[0209] Optionally, the first element may include a Common Info field and at least one Per-STA ProfileSubelement, with each Per-STA Profile Subelement corresponding to one link.

[0210] Optionally, the first field may include the Common Info field, and the second field may include the Per-STAProfile Subelement.

[0211] Optionally, if the UHR Modes Parameters field is carried in the Common Info field, the parameter information identified by the UHR Modes Parameters field can be applied to all affiliated APs of the AP MLD.

[0212] Optionally, if the UHR Modes Parameters field is carried in the Per-STA Profile Subelement, the parameter information identified by the UHR Modes Parameters field can be applied to the first link corresponding to the Per-STA Profile Subelement, specifically to the APs associated with the AP MLD under the first link.

[0213] It is understood that when the UHR Modes Parameters field is carried in the Common Info field, the first element may include only one second identifier field, i.e., one UHR Modes Parameters field; when the UHR Modes Parameters field is carried in the Per-STA Profile Subelement, the first element may include at least one second identifier field. In this case, the number of second identifier fields can be determined according to the number of links to be established between the AP MLD and the non-AP MLD, and there is no restriction here.

[0214] (II) Configuration 2

[0215] Optionally, in some embodiments, the first wireless frame includes a second element, the second element including at least one of the following:

[0216] The fourth identifier field indicates whether the first wireless frame includes operation parameter change information.

[0217] The fifth identification field identifies: operation parameter change information; the operation parameter change information includes at least one of the following: the mode status information and / or the operation parameter information.

[0218] Optionally, the second element can be a Reconfiguration Multi-Link element or a variant of the Multi-Link element. Optionally, the second element can include a Per-STA Profile Subelement.

[0219] The fourth and fifth identifier fields can be carried in the Per-STA Profile Subelement, indirectly indicating the link to which each field in the second element applies. In other words, for a given second element, the fourth and fifth identifier fields corresponding to that second element (Per-STA Profile Subelement) can be applied to the link corresponding to that second element.

[0220] Optionally, the fourth identifier field can be the ReconfigurationOperation Type field in the Per-STA Profile Subelement, and the fifth identifier field can be the UHR ModesUpdate Indication field in the Per-STA Profile Subelement. For example, a Per-STA Profile Subelement may include both the Reconfiguration Operation Type field and the UHR Modes UpdateIndication field.

[0221] Optionally, in some embodiments, the fourth identification field is set to a first parameter value to identify that: the first radio frame is used for operation update, or the first radio frame includes operation parameter update information (i.e., includes the fifth identification field).

[0222] The second element includes at least one third field, and when the fourth identifier field carries the third field, the operation parameter update information is applied to the link corresponding to the third field.

[0223] Optionally, the third field may include the Per-STA Profile Subelement.

[0224] As an example, in a Per-STA Profile Subelement, when the ReconfigurationOperation Type is set to parameter value 5 (i.e., the first parameter value is "5"), the UHR LinkReconfiguration Notify frame can be instructed to include UHR operation parameter update information. In other words, the current Per-STA Profile Subelement can include the UHR Modes Update Indication field, i.e., the fifth identifier field. Furthermore, the fifth identifier field is applied to the link information corresponding to this Per-STA Profile Subelement.

[0225] Optionally, in some embodiments, the fifth identifier field includes at least one of the third subfield and the fourth subfield.

[0226] The third subdomain identifier indicates the operation mode for performing mode state updates and / or operation parameter updates.

[0232] Optionally, in the first radio frame, the Operation Parameter Update Mode Bitmap field (third subfield) may include at least one byte.

[0233] Taking the Operation Parameter Update Mode Bitmap field, which consists of one byte (eight bits B0-B7), as an example, if the AP MLD's associated AP supports NPCA Mode, DBE Mode, and DSO Mode, bits B0-B2 of B0-B7 can be set to correspond to NPCA Mode, DBE Mode, and DSO Mode, respectively. When any bit in B0-B2 is set to "1", it indicates that the AP MLD's mode state and / or operation parameters in the corresponding operation mode should be updated. When any bit in B0-B2 is set to "0", it indicates that the AP MLD's mode state and / or operation parameters should not be updated in the corresponding operation mode. In other words, the AP MLD accepts mode state update requests and / or operation parameter update requests from non-AP MLDs in the corresponding operation mode.

[0234] Optionally, in the first radio frame, the UHR Modes Parameters field (fourth subfield) may carry at least one operation parameter corresponding to the operation mode in which the corresponding bit in the Operation Parameter Update Mode Bitmap field (third subfield) is set to "1", i.e., the operation parameter for updating.

The specific process is as follows:

[0452] 1. After associating with the AP MLD, the Non-AP MLD sends a UHR LinkReconfiguration Request frame (the aforementioned second radio frame) to the AP MLD via a third link. This request aims to update at least one operating mode of the non-AP STA associated with the non-AP MLD on at least one link.

When this identifier is set to 1, it indicates that the Common Info field carries the first identifier field; otherwise (when the identifier is set to 0), it indicates that the Common Info field does not carry the first identifier field.

[0466] b. The first identifier field identifies the operation mode corresponding to the operation parameter update; for example, the Operation ParameterUpdate Mode Bitmap field contains at least one byte in length, such as B0 to B2 corresponding to NPCA Mode, DBE Mode and DSO Mode respectively; when the bit is set to 1, it indicates that AP MLD updates the corresponding operation mode parameters.

[0467] c. One or more second identifier fields (i.e., operation parameter fields): where each second identifier field identifies the operation parameter that needs to be updated corresponding to the operation mode identified in the first identifier field.

[0468] Optionally, the second identifier field may be carried in the Common Info field of the Reconfiguration Multi-Link element, and may contain only one second identifier field; the second identifier field indicates that the updated operating parameters apply to all enabled links;

[0477] The fifth identifier field identifies the operation mode and operation parameters corresponding to the operation parameter update. For example, the fifth identifier field includes a third subfield and a fourth subfield. The third subfield indicates the operation mode corresponding to the updated operation parameters. For example, the Operation Parameter Update Mode Bitmap field contains at least one byte in length, such as B0 to B2, which correspond to NPCA Mode, DBE Mode, and DSO Mode, respectively. When the bit is set to 1, it indicates that AP MLD updates the corresponding operation mode parameters.

[0484] (4) The AP MLD may also send an unsolicited UHR Link Reconfiguration Notify frame (the first radio frame mentioned above) for updating at least one operating parameter of at least one link, even if it does not receive a UHR Link Reconfiguration Request.
