[0002] In-Device Coexistence (IDC) refers to the mutual interference that occurs when multiple wireless technologies operate simultaneously within the same device. Specifically, a WiFi station can share its radio resources with other technologies (such as Bluetooth) or other STAs (Stations) attached to the same MLD (Multi-Link Device). This can cause the WiFi station to be unavailable at certain times and / or on certain frequencies (i.e., Wi-Fi-based communication is unavailable), or it may operate with limited capabilities (i.e., restricted operating mode). In such cases, it is necessary to consider how to design parameter adjustment methods for the WiFi station. Summary of the Invention

[0019] The technical solution provided in this application illustrates a parameter adjustment method for a first operating mode, which supports enabling or disabling the first operating mode for a first device. This process is performed by sending and receiving a first frame, thus clarifying the signaling interaction during the parameter adjustment process for the first operating mode and improving the adjustment efficiency of the parameter adjustment method for the first operating mode. The first frame avoids transmission failures and conflicts caused by untimely adjustment of operating parameters, improving communication efficiency and reliability.

Entering the first operating mode effectively reduces this coexistence interference, improving data transmission stability and performance. In other situations where coexistence interference does not occur, the first frame can be used to allow the first device to exit the first operating mode, improving link utilization and thus data transmission efficiency.

[0041] STA Capability Statement

[0042] EHT-enabled STAs declare themselves as EHT STAs by transmitting EHT Capabilities elements. These EHT Capabilities elements contain numerous fields used to announce the EHT capabilities of the EHT STA. For Access Point (AP) devices, they can carry EHT Capabilities elements in management frames such as beacon frames, probe response frames, association response frames, and reassociation response frames. For non-AP STAs, they can carry EHT Capabilities elements in management frames such as probe request frames, association request frames, and reassociation request frames. The EHT Capabilities element includes EHT MAC capability information fields, EHT PHY (Physical Layer) capability information fields, supported EHT MCS (Modulation and Coding Scheme) and NSS (Number of Spatial Streams) set fields, and EHT PPE threshold fields. The EHT MAC capability information fields defined in the IEEE 802.11 specification are shown in Figure 1.

[0043] The EHT MAC capability information field includes the following subfields: The EPCS (Emergency Preparedness Communication Services) Priority Access Support subfield indicates whether EPCS priority access is supported. The EHT OM Control Support subfield indicates whether receiving frames containing the EHT OM Control subfield is supported. The TXS (Triggered TXOP sharing) Mode 1 Support subfield indicates support for sending or responding to a MU-RTS (Multi-User Request to Send) TXS trigger frame, where the TXS mode field equals 1. In the one-hour embodiment, TXS can also be called Triggered Transmission Scheduling. The TXS Mode 2 Support subfield indicates support for sending or responding to a MU-RTS TXS trigger frame, where the TXS mode field equals 2. The Restricted TWT Support subfield indicates whether Restricted TWT (Restricted TWT) operation is supported. The SCS Traffic Description Support subfield indicates support for transmitting and receiving SCS (Stream Classification Service) description elements that include QoS (Quality of Service) feature sub-elements. The Maximum MPDU Length subfield indicates the maximum length of MPDUs (MAC Protocol Data Units) that the STA can receive. The Maximum A-MPDU Length Exponent Extension subfield indicates the exponential extension of the maximum A-MPDU (Aggregate MAC Protocol Data Unit) length supported during reception.The EHT TRS Support subfield indicates, for non-AP STAs, whether they support sending EHT (Extremely High Throughput) TB (Trigger-Based) PPDU (Physical Layer Protocol Data Unit) after receiving a frame containing the TRS (Trigger-based Response Scheme) control subfield. In TXS Mode 2, the TXOP (Transmission Opportunity) Return Support subfield indicates that, in TXS Mode 2, a non-AP STA supports receiving a frame containing the RDG (Restricted Delivery Group) / More PPDU subfield within the CAS Control subfield. Specifically, this means that a non-AP STA can receive a frame that contains an RDG / More PPDU subfield in the CAS Control subfield of the HE (High Efficiency) variant HT Control field. This subfield indicates that in TXS mode 2, the STA needs to return the allocated TXS time period to the AP. The Two BQRs Support subfield indicates that, for an AP, it supports receiving frames containing two BQR (Block ACK Request) control subfields. For a non-AP STA, it indicates that it supports generating frames containing two BQR control subfields. The EHT Link Adaptation Support subfield indicates support for link adaptation using the ELA (Extremely High Throughput Link Adaptation) control subfield. The Unsolicted EPCS Priority Access Parameter Update subfield indicates whether an STA supporting EPCS priority access also supports updating EPCS priority access parameters in unsolicied mode. The Reserved bit indicates support for further expansion of the EHT MAC capability information field.

[0044] • Operating Mode Indication (OMI)

[0045] Operation mode indication is a procedure used between the OMI initiator and the OMI responder. The station that sends a frame containing the Operation Mode Control subfield is defined as the OMI initiator. The station that receives a frame containing the Operation Mode Control subfield is defined as the OMI responder.

[0046] After association, the OMI initiator can send individually addressed QoSData, QoS Null, or Class 3 management frames to the OMI responder. These frames contain an OM control subfield and / or an EHT OM control subfield, requesting immediate acknowledgment to indicate changes in the Reception Operating Mode (ROM) parameters and / or Transmission Operating Mode (TOM) parameters. The OMI responder receives individually addressed QoS Data, QoS Null, or Class 3 management frames containing OM control subfields and / or EHT OM control subfields indicating changes to the ROM and / or TOM parameters.

[0047] Specifically, in accordance with the receive operation mode indication requirements, the OMI initiator should indicate changes to its receive operation mode parameters by including the OM control subfield and / or EHT OM control subfield in a QoSData, QoS Null, or Class 3 management frame. This frame requests immediate acknowledgment, and the target receive address of the frame is the OMI responder. The ROM indication allows the OMI initiator to adapt to the maximum operating channel width and / or the maximum number of spatial streams (Nss) that can be received from the OMI responder. An OMI initiator sending a frame containing the OM control subfield should change its OMI parameters, Rx NSS, and channel width as follows: when the OMI initiator changes the ROM parameter from high to low, it should only change the parameter after receiving an immediate acknowledgment TXOP from the OMI responder; when the OMI initiator changes the ROM parameter from low to high, it should only change the parameter after expecting to receive an acknowledgment TXOP from the OMI responder.

[0048] As required by the Transmission Operation Mode (TOM) instruction, the OMI initiator should indicate changes to its TOM parameters by including the OM Control subfield in a QoSData, QoS Null, or Class 3 management frame. This frame requests immediate acknowledgment, and the target receiving address of the frame is the OMI responder. The TOM instruction allows the OMI initiator to suspend and resume responses to different variants of the trigger frame and TRS control subfield based on the Uplink Multi-User Disable (UL MU Disable) and Uplink Multi-User Data Disable (UL MU Data Disable) subfield settings, or to adapt to its maximum transmittable operating channel width and / or the maximum number of Space-Time Streams (Nsts) in response to trigger frames sent by the OMI responder.

[0049] Specifically, frames requesting immediate acknowledgment include QoS empty frames carrying a Normal Ack or Implicit Block Acknowledgment Request (BAR) acknowledgment policy, as well as QoS data frames and action frames.

[0050] The control information subfield within the OM control subfield contains information related to changes in the operating mode (OM) of the STA transmitting the frame containing this information (see IEEE 802.11 specification 26.9 (Operating Mode Indication)). The format of the OM control subfield is shown in Figure 2, and the information in the subfields included in the OM control subfield is as follows: The Receive NSS (Rx NSS) subfield indicates the maximum number of spatial streams supported by the receiver. The Channel Width subfield indicates the channel width for transmission. The Uplink Multi-User Disable subfield indicates whether the STA disables uplink multi-user transmission. The Transmit NSTS (Number of Spatial Streams) subfield indicates the number of independent spatial streams used by the STA when transmitting data. The Emergency Response Single User Disable subfield controls whether Emergency Response (ER) Single User (SU) functionality is disabled. The Downlink Multi-User Multiple-Input Multiple-Output Recommendation subfield provides recommendations regarding channel state information in downlink multi-user multiple-input multiple-output (DL MU-MIMO) transmissions. The Uplink Multi-User Disable subfield is used to indicate whether the STA disables uplink multi-user data transmission. The control information subfield in the EHT OM control subfield contains information about the OM changes of the STA sending the frame containing this information under 320MHz bandwidth, Tx NSTS (Transmit Spatial Stream Count) expansion, and Rx NSS (Receive Spatial Stream Count) expansion (see IEEE 802.11 specification 35.9 (Operating Mode Indication), as described above). The format of the EHT OM control subfield is shown in Figure 3.

[0051] Multi-link operation

[0052] The IEEE 802.11be standard defines multilink operation (MLO) and AP MLD and non-AP MLD devices with multilink operation capabilities. Multiple links can be established between AP MLD and non-AP MLD on multiple different frequency bands / channels.

[0053] As shown in Figure 4, three links, referred to as link 1, link 2, and link 3, are established between the AP MLD and the non-AP MLD on the 2.4GHz, 5GHz, and 6GHz bands, respectively. These three links can operate simultaneously. AP 1 operating on link 1 (2.4GHz), AP 2 operating on link 2 (5GHz), and AP 3 operating on link 3 (6GHz) are respectively referred to as affiliated APs of the AP MLD. Similarly, non-AP STA 1 operating on link 1 (2.4GHz), non-AP STA 2 operating on link 2 (5GHz), and non-AP STA 3 operating on link 3 (6GHz) are respectively referred to as affiliated non-AP STAs of the non-AP MLD.

[0054] Coexistence operation

[0055] Coexistence operation (such as coexistence IDC within a device) refers to the ability of an IEEE 802.11 (i.e., Wi-Fi) site to share its radio resources with other technologies (such as Bluetooth BT) or other STAs attached to the same MLD, which may make the Wi-Fi site unavailable at certain times and / or at certain frequencies (i.e., Wi-Fi-based communication is unavailable), or may operate with limited operational capabilities.

[0056] • Restricted mode operation

[0057] This refers to the operating mode of the aforementioned WiFi site under limited operational capabilities. Operational capabilities refer to the capabilities related to receiving and / or sending data frames. Capabilities related to receiving data frames can be called receiving capabilities; capabilities related to sending data frames can be called sending capabilities. Besides data frames, it can also refer to receiving and / or sending data packets, data segments, datagrams, data streams, signals, information, and other equivalent concepts, which will not be elaborated upon here.

[0058] Figure 5 is a schematic diagram of a communication system provided in an exemplary embodiment of this application. This communication system includes terminals and terminals, or terminals and network devices, or access points (APs) and stations (STAs), and this application does not limit the specific examples. This application uses an example communication system including AP110 and STA120 for illustration.

[0059] In some scenarios, an AP can also be called an AP STA, meaning that in a sense, an AP is also a type of STA. In other scenarios, a STA can also be called a non-AP STA.

[0060] In some embodiments, a STA may include an AP STA and a non-AP STA. Communication in the communication system can be between an AP and a non-AP STA, between two non-AP STAs, or between a STA and a peer STA. A peer STA can refer to a device communicating with the STA from the other end; for example, a peer STA may be an AP or a non-AP STA. Exemplarily, there are two communication scenarios between a STA and an AP: uplink communication and downlink communication. Uplink communication involves the STA sending signals to the AP; downlink communication involves the AP sending signals to the STA. An AP acts as a bridge connecting wired and wireless networks, primarily connecting various wireless network clients together and then connecting the wireless network to the Ethernet. An AP device can be a terminal device (such as a mobile phone) or a network device (such as a router) with a Wireless Fidelity (WiFi) chip.

[0061] In the embodiments of this application, the STA can be a device with wireless transceiver capabilities, such as one that supports the 802.11 series of protocols and can communicate with the AP or other STAs. For example, an STA is any user communication device that allows users to communicate with the AP and thus with the WLAN. STAs can be, for example, User Equipment (UE), Mobile Station (MS), Mobile Terminal (MT), Access Terminal, User Unit, User Station, Mobile Station, Mobile Station, Remote Station, Remote Terminal, Mobile Device, User Terminal, Terminal, Wireless Communication Equipment, User Agent, or User Equipment, etc.

[0062] In this application embodiment, the STA can also be a device that provides voice / data / image connectivity to the user, such as a handheld device, vehicle device, home device, home appliance, gaming device, etc., with wireless connection function or equipped with a wireless communication module. Examples include: mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving vehicles, drones or aerial photography equipment, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, cellular phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices or other processing devices connected to a wireless modem, in-vehicle devices, wearable devices, terminal devices in 5G networks, or future evolved Public Land mobile communication networks. Terminal devices in a Mobile Network (PLMN) can also include televisions, refrigerators, washing machines, kitchen appliances, door locks, fish tanks, robot vacuum cleaners, game consoles, cameras / camcorders, etc., which are not limited to this in the embodiments of this application.

[0063] By way of example and not limitation, in this embodiment, the STA can also be a wearable device. Wearable devices, also known as wearable smart devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Examples include smartwatches or smart glasses, as well as devices that focus on a specific type of application function and require cooperation with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0064] Furthermore, in this embodiment, the STA can also be a terminal device in an Internet of Things (IoT) system. IoT is an important component of future information technology development, and its main technical feature is connecting objects to networks through communication technologies, thereby realizing an intelligent network of human-machine interconnection and object-to-object interconnection. In this embodiment, IoT technology can achieve massive connectivity, deep coverage, and low terminal power consumption through technologies such as narrowband (NB).

[0065] Furthermore, in this embodiment, the STA can be an in-vehicle communication device in the vehicle-to-everything (V2X) system or the vehicle itself. The communication methods in the V2X system are collectively referred to as V2X (where X represents anything). For example, V2X communication includes: vehicle-to-vehicle (V2V) communication, vehicle-to-infrastructure (V2I) communication, vehicle-to-pedestrian (V2P) communication, or vehicle-to-network (V2N) communication, etc.

[0066] It should be understood that the role of a STA in a communication system is not absolute. For example, in some scenarios, when a mobile phone connects to a router, it acts as a non-AP STA; when the phone serves as a hotspot for other mobile phones, it acts as an AP. APs and non-AP STAs can be devices used in vehicle-to-everything (V2X) networks, IoT nodes and sensors in the Internet of Things (IoT), smart cameras, smart remote controls, smart water and electricity meters in smart homes, and sensors in smart cities.

[0067] In some embodiments, the non-AP STA may support, but is not limited to, the 802.11be standard. The non-AP STA may also support various current and future 802.11 family of Wireless Local Area Network (WLAN) standards, such as 802.11bn, 802.11ax, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a. In some embodiments, the AP may be a device that supports the 802.11be standard. The AP may also be a device that supports various current and future 802.11 family of WLAN standards, such as 802.11bn, 802.11ax, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a.

[0068] In this application embodiment, the STA can be a mobile phone, tablet computer, computer, virtual reality device, augmented reality device, communication device in industrial control, set-top box, communication device in autonomous driving, vehicle communication device, communication device in telemedicine, communication device in smart grid, communication device in transportation safety, communication device in smart city, or communication device in smart home, wireless communication chip, etc., that supports WLAN / Wi-Fi technology. WLAN technology can support frequency bands including but not limited to: low frequency band (2.4GHz, 5GHz, 6GHz) and high frequency band (60GHz).

[0069] One or more links exist between a site and an access point. In some embodiments, the site and access point support multi-band communication, for example, communicating simultaneously on the 2.4 GHz, 5 GHz, 6 GHz, and 60 GHz bands, or simultaneously communicating on different channels within the same (or different) bands, improving communication throughput and / or reliability between devices. Such devices are commonly referred to as multi-band devices, and may also be called multi-link devices (MLDs), sometimes also called multi-link entities or multi-band entities. A multi-link device can be an access point device or a site device. If the multi-link device is an access point device, it includes one or more access points (APs); if the multi-link device is a site device, it includes one or more non-AP STAs. A multi-link device including one or more APs can also be called an AP, and a multi-link device including one or more non-AP STAs can also be called a Non-AP. In this embodiment, a Non-AP can be called a STA.

[0070] In this embodiment of the application, an AP may include multiple APs, and a Non-AP may include multiple STAs. Multiple links may be formed between the multiple APs in the AP and the multiple STAs in the Non-AP. Data communication may be performed between the APs in the AP and the corresponding STAs in the Non-AP through the corresponding links.

[0071] An Access Point (AP) is a device deployed in a wireless local area network (WLAN) to provide wireless communication functionality to a Station (STA). A STA can include: user equipment, access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, wireless communication device, user agent, or user equipment. Optionally, a STA can also be a cellular phone, cordless phone, session initiation protocol phone, wireless local loop station, personal digital assistant, handheld device with wireless communication functionality, computing device or other processing device connected to a wireless modem, vehicle-mounted device, or wearable device; this application embodiment is not limited in this regard.

[0072] In the embodiments of this application, both STA and AP support the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, but are not limited to the IEEE 802.11 standard.

[0073] Figure 6 illustrates a flowchart of a parameter adjustment method provided in an exemplary embodiment of this application. The method is performed by a first device, which may be a STA or AP shown in Figure 5. The method includes:

[0074] Step 210: Receive and / or send a first frame, the first frame being used to indicate whether the first operating mode is enabled, and / or to adjust the operating parameters related to the first operating mode.

[0075] The first operating mode is at least one of the following: restricted operating mode; receiving capability adjustment operating mode; transmitting capability adjustment operating mode; receiving and transmitting capability adjustment operating mode; operating mode related to coexistence operation; and operating mode under interference scenarios.

[0076] Send a first frame to enable a first operating mode; or, send a first frame to adjust operating parameters related to the first operating mode; or, send a first frame to disable the first operating mode; or, send a first frame to indicate enabling the first operating mode and adjusting operating parameters related to the first operating mode; or, send a first frame to indicate disabling first operating parameters and adjusting operating parameters related to the first operating mode; or, receive a first frame to enable the first operating mode; or, receive a first frame to adjust operating parameters related to the first operating mode; or, receive a first frame to disable the first operating mode; or, receive a first frame to indicate enabling the first operating mode and adjusting operating parameters related to the first operating mode; or, receive a first frame to indicate disabling first operating parameters and adjusting operating parameters related to the first operating mode.

[0077] In some embodiments, enabling the first operating mode can also be referred to as entering the first operating mode, or as turning on the first operating mode, or as adjusting the operating parameters to the operating parameters corresponding to the first operating mode.

[0078] In some embodiments, disabling the first operating mode can be referred to as exiting the first operating mode, or as closing the first operating mode. It can also be understood as adjusting the operating parameters to the operating parameters corresponding to the second operating mode. The second operating mode can be an unrestricted operating mode, or a normal operating mode, or an operating mode unrelated to coexisting operations, or an operating mode in an undisturbed scenario, or an operating mode before entering the restricted operating mode, etc.

[0079] In some embodiments, adjusting the operating parameters related to the first operating mode can be understood as a further adjustment of the operating parameters under the first operating mode, such as adjusting the operating parameters from the first operating parameters corresponding to the first operating mode to the second operating parameters corresponding to the first operating mode. It can also be understood as an adjustment to the first operating mode, such as changing from the receiving capability adjustment operating mode to the transmitting and receiving capability adjustment operating mode.

[0080] In some embodiments, adjusting the operating parameters related to the first operating mode can also be replaced by an equivalent description such as updating the operating parameters related to the first operating mode, and this application embodiment does not limit this.

[0081] In some embodiments, the receiving capability adjustment operation mode may also be referred to as the receiving capability limited operation mode or other equivalent names; the transmitting capability adjustment operation mode may also be referred to as the transmitting capability limited operation mode or other equivalent names; the receiving and transmitting capability adjustment operation mode may also be referred to as the receiving and transmitting capability limited operation mode or other equivalent names.

[0082] In some embodiments, operating parameters refer to parameters related to the operational capability of the first device. Operating parameters may also be referred to as communication parameters, transmit / receive parameters, or other equivalent terms. This application does not limit this to specific terms.

[0083] In some embodiments, adjusting the operating parameters related to the first operating mode may involve adjusting the operating parameters related to the first operating mode to a target parameter value; or it may involve enabling the operating parameters related to the first operating mode and their corresponding parameter values. That is, different operating modes may correspond to the same operating parameters, but the parameter values ​​of the operating parameters may be different in different operating modes; different operating modes may correspond to different operating parameters; or different operating modes may share some operating parameters, but there may also be one or more operating parameters that can be used independently by different operating modes.

[0084] In some embodiments, the operating parameters associated with the first operating mode can be understood as the operating parameters corresponding to the first operating mode, and / or, the operating parameters corresponding to the second operating mode, etc. The second operating mode is an operating mode different from the first operating mode. Adjusting the operating parameters to the operating parameters corresponding to the first operating mode can be understood as entering the first operating mode after adjustment, or switching from another operating mode to the first operating mode, where the other operating mode can be the second operating mode; adjusting the operating parameters to the operating parameters corresponding to the second operating mode can be understood as entering the second operating mode after adjustment, or switching from another operating mode (such as the first operating mode) to the second operating mode, which can also be said to be exiting another operating mode (such as the first operating mode).

[0085] In some embodiments, the first frame is further used for the second device to enable the first operating mode, and / or disable the first operating mode, and / or adjust operating parameters related to the first operating mode. The second device is a device associated with the first device. The second device may also be referred to as a device that shares one or more links with the first device; or in other words, the second device is a device that shares one or more links with the first device.

[0086] In summary, the method provided in this application embodiment illustrates a parameter adjustment method for a first operating mode, which supports enabling or disabling the first operating mode for the first device. This process is performed by sending and receiving the first frame, thus clarifying the signaling interaction during the parameter adjustment process for the first operating mode and improving the adjustment efficiency of the parameter adjustment method for the first operating mode. The first frame avoids transmission failures and conflicts caused by untimely adjustment of operating parameters, improving communication efficiency and reliability. Furthermore, adjusting operating parameters through the first frame allows the first device to enter or exit the first operating mode. This first operating mode is at least one of the following: a restricted operating mode, a receiving capability adjustment operating mode, a transmitting capability adjustment operating mode, a transceiver capability adjustment operating mode, an operating mode related to coexistence operation, and an operating mode under interference scenarios. Entering the first operating mode avoids coexistence interference caused by multiple links operating simultaneously, which affects signal quality and data transmission reliability. Entering the first operating mode effectively reduces this coexistence interference, improving the stability and performance of data transmission. At other times when coexistence interference does not occur, the first frame can be used to allow the first device to exit the first operating mode, improving link utilization and thus data transmission efficiency.

[0087] Figure 7 illustrates a flowchart of a parameter adjustment method provided in an exemplary embodiment of this application. The method is performed by a second device, which may be a STA or AP shown in Figure 5. The method includes:

[0091] In some embodiments, enabling the first operating mode can also be referred to as entering the first operating mode, or as turning on the first operating mode, or as adjusting the operating parameters to the operating parameters corresponding to the first operating mode.

[0092] In some embodiments, disabling the first operating mode can be referred to as exiting the first operating mode, or as closing the first operating mode. It can also be understood as adjusting the operating parameters to the operating parameters corresponding to the second operating mode. The second operating mode can be an unrestricted operating mode, or a normal operating mode, or an operating mode unrelated to coexisting operations, or an operating mode in an undisturbed scenario, or an operating mode before entering the restricted operating mode, etc.

[0093] In some embodiments, adjusting the operating parameters related to the first operating mode can be understood as a further adjustment of the operating parameters under the first operating mode, such as adjusting the operating parameters from the first operating parameters corresponding to the first operating mode to the second operating parameters corresponding to the first operating mode. It can also be understood as an adjustment to the first operating mode, such as changing from the receiving capability adjustment operating mode to the transmitting and receiving capability adjustment operating mode.

[0094] In some embodiments, adjusting the operating parameters related to the first operating mode can also be replaced by an equivalent description such as updating the operating parameters related to the first operating mode, and this application embodiment does not limit this.

[0095] In some embodiments, the receiving capability adjustment operation mode may also be referred to as the receiving capability limited operation mode or other equivalent names; the transmitting capability adjustment operation mode may also be referred to as the transmitting capability limited operation mode or other equivalent names; the receiving and transmitting capability adjustment operation mode may also be referred to as the receiving and transmitting capability limited operation mode or other equivalent names.

[0096] In some embodiments, operating parameters refer to parameters related to the operational capability of the first device. Operating parameters may also be referred to as communication parameters, transmit / receive parameters, or other equivalent terms. This application does not limit this to specific terms.

[0097] In some embodiments, adjusting the operating parameters related to the first operating mode may involve adjusting the operating parameters related to the first operating mode to a target parameter value; or it may involve enabling the operating parameters related to the first operating mode and their corresponding parameter values. That is, different operating modes may correspond to the same operating parameters, but the parameter values ​​of the operating parameters may be different in different operating modes; different operating modes may correspond to different operating parameters; or different operating modes may share some operating parameters, but there may also be one or more operating parameters that can be used independently by different operating modes.

[0098] In some embodiments, the operating parameters associated with the first operating mode can be understood as the operating parameters corresponding to the first operating mode, and / or, the operating parameters corresponding to the second operating mode, etc. The second operating mode is an operating mode different from the first operating mode. Adjusting the operating parameters to the operating parameters corresponding to the first operating mode can be understood as entering the first operating mode after adjustment, or switching from another operating mode to the first operating mode, where the other operating mode can be the second operating mode; adjusting the operating parameters to the operating parameters corresponding to the second operating mode can be understood as entering the second operating mode after adjustment, or switching from another operating mode (such as the first operating mode) to the second operating mode, which can also be said to be exiting another operating mode (such as the first operating mode).

[0099] In some embodiments, the first frame is further used for the second device to adjust operating parameters related to the first operating mode. The second device is a device associated with the first device. The second device may also be referred to as a device that shares one or more links with the first device; or, in other words, the second device is a device that shares one or more links with the first device.

[0100] In summary, the method provided in this application embodiment illustrates a parameter adjustment method for a first operating mode, which supports enabling or disabling the first operating mode for the second device. This process is performed by transmitting and receiving a first frame, thus clarifying the signaling interaction during the parameter adjustment process for the first operating mode and improving the adjustment efficiency of the parameter adjustment method for the first operating mode. The first frame avoids transmission failures and conflicts caused by untimely adjustment of operating parameters, improving communication efficiency and reliability. Furthermore, adjusting operating parameters through the first frame allows the second device to enter or exit the first operating mode. This first operating mode is at least one of a restricted operating mode, a receive capability adjustment operating mode, a transmit capability adjustment operating mode, a transmit / receive capability adjustment operating mode, an operating mode related to coexistence operation, or an operating mode under interference scenarios. Entering the first operating mode can avoid coexistence interference caused by multiple links working simultaneously or multiple links having strong signals, which affects signal quality and data transmission reliability. In other words, even if the second device enters the first operating mode, it effectively reduces such coexistence interference, improving the stability and performance of data transmission. At other times when there is no coexistence interference, the utilization rate of the link can be improved by having the second device exit the first operating mode in the first frame, thereby improving data transmission efficiency.

[0101] The following section will introduce the first frame and the first operation mode.

[0102] 1. The first frame and the first operation mode.

[0103] In some embodiments, the first operating mode has at least one of the following characteristics: limited operating capability; limited receiving capability; limited transmitting capability; limited transceiver capability; support for adjusting receiving capability; support for adjusting transmitting capability; support for adjusting transceiver capability; operation under limited operating capability; operation under reduced operating capability; in an interference-affected scenario; related to coexistence operation; support for real-time adjustment of operating parameters; support for real-time adjustment of operating capability. Here, "limited" refers to a decrease in capability, or in other words, the operating capability in the first operating mode is lower than that in the normal operating mode. Alternatively, it can be said that the receiving capability in the first operating mode is lower than that in the normal operating mode, or that the transmitting capability in the first operating mode is lower than that in the normal operating mode, or that the transceiver capability in the first operating mode is lower than that in the normal operating mode. It should be noted that the above expressions of the characteristics of the first operating mode are different expressions with the same meaning.

[0104] In some embodiments, the first device is an MLD within an MLO, such as a non-AP MLD or an AP MLD; or, the first device is a non-MLO device. In some embodiments, the second device is an MLD within an MLO, such as a non-AP MLD or an AP MLD; or, the second device is a non-MLO device.

[0105] In some embodiments, the first device and the second device establish one or more links on multiple different frequency bands / channels. When both the first device and the second device are MLDs (Multi-Level Devices), one or more links exist between one or more sites attached to the first device and one or more sites attached to the second device. For example, a link is established between each of the multiple sites attached to the first device and one of the multiple sites attached to the second device.

[0106] In some embodiments, the first device is an MLD; the first frame is used to indicate at least one of the following: enabling a first operating mode of one or more sites attached to the first device; disabling the first operating mode of one or more sites attached to the first device; adjusting or updating operating parameters of one or more sites attached to the first device. In some embodiments, the second device is an MLD; the first frame is used to indicate at least one of the following: enabling a first operating mode of one or more sites attached to the first device; disabling the first operating mode of one or more sites attached to the first device; adjusting or updating operating parameters of one or more sites attached to the first device.

[0107] In some embodiments, the first device is an MLD; the first frame is used to indicate at least one of the following: enabling a first operating mode of one or more sites attached to the sending device of the first frame; disabling the first operating mode of one or more sites attached to the sending device of the first frame; adjusting or updating the operating parameters of one or more sites attached to the sending device of the first frame. In some embodiments, the second device is an MLD; the first frame is used to indicate at least one of the following: enabling a first operating mode of one or more sites attached to the sending device of the first frame; disabling the first operating mode of one or more sites attached to the sending device of the first frame; adjusting or updating the operating parameters of one or more sites attached to the sending device of the first frame.

[0108] In some embodiments, the first device is a non-MLO device; the first frame is used to indicate at least one of the following: enabling a first operating mode of the sending device of the first frame; disabling the first operating mode of the sending device of the first frame; adjusting or updating the operating parameters of the sending device of the first frame. In some embodiments, the second device is a non-MLO device; the first frame is used to indicate at least one of the following: enabling a first operating mode of the sending device of the first frame; disabling the first operating mode of the sending device of the first frame; adjusting or updating the operating parameters of the sending device of the first frame.

[0109] In this context, the sending device of the first frame refers to the device that sends the first frame; it can be either the first device or the second device.

[0110] In some embodiments, the first device adjusts operating parameters related to a first operating mode at one or more sites attached to the first device based on a first frame. The one or more sites attached to the first device are indicated by the first frame. In some embodiments, the second device adjusts operating parameters related to the first operating mode at one or more sites attached to the second device based on a first frame. The one or more sites attached to the second device are indicated by the first frame.

[0111] In some embodiments, a site attached to the first device is equivalent to a site in an MLD, or can be understood as a non-MLO device, or even a non-MLD. A site attached to the second device is equivalent to a site in an MLD; or can be understood as a non-MLO device, or even a non-MLD. That is, the first frame can be understood as indicating the site corresponding to one or more links in the multi-link device that need to adjust operating parameters; or, the first frame can be understood as indicating the site in the multi-link device that adjusts operating parameters and operates on the same link, wherein the multi-link device includes at least two links, and the link that needs to adjust operating parameters is one or more links included in the multi-link device; or, the first frame can be understood as indicating that some links in the multi-link device adjust operating parameters, specifically, the site operating on some links adjusts operating parameters, with one link corresponding to a group of sites.

[0112] In some embodiments, the first frame is transmitted on one link of the multi-link device, but the first frame is used to indicate parameter adjustment operations corresponding to at least one link in the multi-link device. That is, when the first device or the second device determines that operation parameters need to be adjusted for some links, it determines the links whose operation parameters need to be adjusted, and sends the first frame through a station attached to the first device (denoted as the first station) or a station attached to the second device (denoted as the second station) to indicate the adjustment of operation parameters for the partial links. For the station attached to the first device or the station attached to the second device operating on the partial links, after receiving the first frame, the first station or the second station will transmit the first frame to other stations in the first device or the second device through physical connections (such as through ports and connection cables) or network layers (such as MAC layers, application layers, etc.).

[0113] In summary, the method provided in this application illustrates the meaning of the first operating mode. In some scenarios, enabling the first operating mode is necessary to reduce or limit the operational capabilities of one or more sites attached to the second device or one or more sites attached to the first device; that is, it is necessary to adjust the operating parameters and enter the first operating mode to reduce coexistence interference. In other scenarios, if transmission relies on the link between the first and second devices, it is necessary to disable the first operating mode or adjust the operating parameters related to the first operating mode to improve the operational capabilities of the second or first device. Furthermore, the second and first devices can be devices corresponding to links in a multi-link device. Due to the close proximity of communication modules within a multi-link device and its design characteristics, coexistence interference within the devices is more likely to occur. The method shown in this application allows entering the first operating mode to avoid coexistence interference caused by multiple links working simultaneously or having strong signals, thus preventing interference that could affect signal quality and data transmission reliability. In other words, entering the first operating mode for one or more sites attached to the first or second device effectively reduces this coexistence interference, improving the stability and performance of data transmission. In other situations where there is no coexistence interference, the utilization of the link can be improved by having one or more stations attached to the first or second device exit the first operating mode in the first frame, thereby improving data transmission efficiency.

[0114] The following section introduces the operating parameters related to the first operating mode.

[0115] 2. Operating parameters related to the first operating mode.

[0116] In some embodiments, the operating parameters include at least one of the following: maximum PPDU reception duration; maximum PPDU transmission duration; maximum MCS reception; maximum MCS transmission; whether LDPC mode is supported; whether HT instant BA mode is supported; disabled subchannels; maximum A-MPDU length exponent; maximum A-MPDU length exponent extension; minimum MPDU start interval; MPDU multi-user spacing factor; TID (Transaction Identifier) ​​aggregation transmission limit; TID aggregation reception limit; segmented A-MSDU fragmentation mode; maximum transmit power; minimum target receive power; recommended AC (Access Category).

[0117] In some embodiments, the maximum PPDU reception duration is used to indicate the maximum PPDU duration supported by one or more sites attached to the first device (or one or more sites attached to the second device) at the time of reception. Optionally, the unit is microseconds, milliseconds, nanoseconds, etc.

[0118] In some embodiments, the maximum PPDU transmission duration is used to indicate the maximum PPDU duration supported by one or more sites attached to the first device (or one or more sites attached to the second device) at the time of transmission. Optionally, the unit is microseconds, milliseconds, nanoseconds, etc.

[0119] In some embodiments, the maximum transmit MCS is used to indicate the maximum MCS supported by one or more stations attached to the first device (or one or more stations attached to the second device) during transmission. For example, the maximum transmit MCS can be an index value or a specific parameter value. The MCS corresponds to the modulation and coding used in the data domain of the PPDU, and the parameter value corresponding to each index value is agreed upon by the protocol or pre-configured. For instance, if the maximum transmit MCS is an index value of 8 (i.e., corresponding to 256-QAM modulation, 3 / 4 code rate), it indicates that the STA supports a maximum modulation order of 256-QAM with a corresponding code rate of 3 / 4 during transmission.

[0120] In some embodiments, receiving maximum MCS is used to indicate the maximum MCS supported by one or more sites attached to the first device (or one or more sites attached to the second device) at the time of reception. For a specific representation, please refer to the above description of "sending maximum MCS," which will not be repeated here.

[0121] In some embodiments, whether LDPC (Low-Density Parity-Check) mode is supported refers to whether one or more stations attached to the first device (or one or more stations attached to the second device) support LDPC mode in transmission and / or reception. For example, in a scenario where the first operating mode is enabled, the LDPC mode subfield indicates whether the STA supports LDPC in transmission and / or reception when it is in the first operating mode. For instance, a value of 1 for the LDPC mode subfield indicates that the STA supports LDPC in transmission and / or reception; otherwise, it is set to 0. The LDPC mode indicates whether LDPC codes are supported. LDPC codes are efficient forward error correction codes with high error correction capability and low decoding complexity. They implement the encoding and decoding process through a sparse parity-check matrix, and this sparsity gives LDPC codes significant advantages in error correction performance and decoding complexity.

[0122] In some embodiments, whether HT Immediate Block Acknowledgment (HT-Immediate BA) mode is supported refers to whether the HT-Immediate BA protocol is active or suspended. HT Immediate BA is an immediate acknowledgment mechanism that allows the receiver to send a block acknowledgment frame immediately after receiving a data frame, instead of waiting for a period of time. This mechanism reduces the number of acknowledgment frames and the corresponding frame interval time, thereby improving channel utilization and network throughput; with immediate acknowledgment, lost data frames can be detected and retransmitted more quickly, improving the reliability of data transmission; it has significant advantages in application scenarios requiring rapid response.

[0123] In some embodiments, a disabled subchannel refers to a subchannel that is disabled within the BSS bandwidth; the disabled subchannel may also be replaced by other equivalent terms such as enabled subchannel. An enabled subchannel refers to a subchannel that is enabled within the BSS bandwidth. The disabled subchannel can be indicated by a subchannel identifier (such as a unique identifier, index value, etc.) or by a bitmap. For example, if the BSS bandwidth is 320MHz and each subchannel corresponds to 20MHz, a 16-bit bitmap can be used to indicate disabled and / or enabled subchannels, where the lowest bit corresponds to the 20MHz subchannel within the BSS bandwidth and is the lowest frequency among all 20MHz subchannels within the BSS bandwidth. Each consecutive bit in the bitmap corresponds to the next higher frequency 20MHz subchannel. If the corresponding bit in the bitmap within the BSS bandwidth range is set to 1, it indicates that the corresponding 20MHz sub-channel is punctured, meaning the sub-channel is disabled or not used during transmission. Conversely, setting the corresponding bit in the disabled sub-channel bitmap within the BSS bandwidth range to 0 indicates that the corresponding 20MHz sub-channel is not punctured, meaning the sub-channel is enabled or used during transmission. Different bitmap sizes can be set depending on the BSS bandwidth range.

[0124] In some embodiments, the Ack-Enabled aggregation mode is used to indicate whether one or more sites attached to the first device (or one or more sites attached to the second device) support receiving an A-MPDU containing two or more frames, wherein at least one frame requests an Ack frame or acknowledgment context in a Multi-STA BlockAck frame.

[0125] In some embodiments, the Maximum A-MPDU Length Exponent indicates the maximum length of A-MPDUs that the STA is allowed to send or receive. This field defines a length of 2(3 + MaximumA-MPDU). Length Exponent) -1 byte.

[0126] In some embodiments, the maximum A-MPDU length exponential extension is used to indicate the exponential extension of the maximum length of the A-MPDU supported when one or more sites attached to the first device (or one or more sites attached to the second device) transmit or receive, and the field sets the maximum value of the A-MPDU exponential extension.

[0127] In some embodiments, the minimum MPDU start spacing is used to indicate the minimum time interval between adjacent MPDU starts within an A-MPDU that one or more sites attached to a first device (or one or more sites attached to a second device) can transmit or receive, as measured in PHY SAP.

[0128] In some embodiments, the MPDU MU Spacing Factor is used to calculate the value by which the minimum starting spacing of an MPDU is multiplied, i.e., the product factor used when calculating the minimum starting spacing of an MPDU; the calculated minimum starting spacing of an MPDU refers to the minimum spacing between the start of adjacent MPDUs within an A-MPDU that can be sent by one or more sites attached to the first device (or one or more sites attached to the second device), wherein the minimum spacing is represented by the number of bytes (N) between the start of two consecutive MPDUs in an A-MPDU, as measured in PHY SAP.

[0129] In some embodiments, the minimum spacing between the start of adjacent MPDUs within a transmittable A-MPDU can be represented by either the Minimum MPDU Start Spacing or the MPDU MU Spacing Factor.

[0130] In some embodiments, the TID Aggregation Tx Limit represents the maximum number of TIDs corresponding to the MPDUs that can be aggregated by one or more sites attached to the first device (or one or more sites attached to the second device) for multi-TID A-MPDUs. It can also be called the TID Aggregation Sending Limit. The value of the TID Aggregation Tx Limit subfield is less than or equal to MT+1, where MT is the value indicated in the Multi-TID Aggregation Tx Support subfield of the HE MAC Capabilities Information field in the HE Capabilities element sent by the STA.

[0131] In some embodiments, the TID Aggregation Rx Limit represents the maximum number of TIDs corresponding to MPDUs that can be aggregated from multiple sites attached to the first device (or multiple sites attached to the second device) that can receive multi-TID A-MPDUs. The value of the TID Aggregation Rx Limit subfield is less than or equal to MR+1, where MR is the value indicated in the Multi-TID Aggregation Rx Support subfield of the HE MAC Capabilities Information field in the HE Capabilities element sent by the STA.

[0132] In some embodiments, fragmentation mode indicates whether fragmentation and / or defragmentation are supported, wherein fragmentation means that the MAC of one or more sites attached to the first device (or one or more sites attached to the second device) can fragment and reassemble the MSDU or MMPDU carried in a separately addressed MPDU.

[0133] In some embodiments, the A-MSDU fragmentation mode indicates whether sending or receiving fragmented A-MSDUs is supported.

[0134] In some embodiments, the maximum transmit power represents the total transmit power at the transmit antenna connector of all antennas used to transmit PPDUs at one or more sites attached to the first device (or one or more sites attached to the second device), in dBm / 20MHz. The transmit power PTX in dBm / 20MHz is calculated as PTX = -20 + 2 × FVal, where FVal is the value of the maximum transmit power subfield, and 31 is a reserved value.

[0135] In some embodiments, the minimum target received power represents the minimum signal power expected to be received, measured at the antenna connector of one or more sites attached to the first device (or one or more sites attached to the second device) and averaged on the antenna. The minimum target received power (in dBm) is Targetpwr = -90 + 2 × Fval, where Fval is the value of the minimum target received power subfield. Using the information indicated by the minimum target received power subfield, the responder can better adjust the transmit power and select an appropriate modulation and coding scheme based on the initiator's minimum target received power requirement.

[0136] In some embodiments, a Preferred AC represents the lowest AC recommended in the MPDU carried in the PPDU that one or more sites attached to the first device (or one or more sites attached to the second device) can send or receive. Preferred ACs enable initiators and responders to better utilize transmission resources for the transmission and scheduling of higher-priority service data.

[0137] In summary, the method provided in this application embodiment shows adjusted operating parameters, which are set for a first operating mode. By using the operating parameters shown above, the operating capabilities of the second device or the first device are limited, thereby achieving the purpose of the second device or the first device performing transmission under limited operating capabilities.

[0138] 3. Interaction during parameter adjustment.

[0139] In some embodiments, the operating parameters are parameters used for communication between the first device and the second device, or parameters used for communication between a station attached to the first device and a station attached to the second device. Since the stations attached to the first device and the second device, operating on the same link, support communication, adjusting the operating parameters requires joint execution by the related stations. Therefore, when one of the stations attached to the first device or the second device needs to enter or exit a first operating mode, it needs to instruct its corresponding peer station on the appropriate parameter adjustment operation, such as the operating parameters to be adjusted, the adjusted parameter values, etc. The party initiating the parameter adjustment can be called the initiator, and the peer station can be called the responder. After receiving the parameter adjustment operation instructed by the initiator, the responder needs to execute the parameter adjustment operation accordingly to ensure normal communication between the initiator and the responder, or, based on its own capabilities and configuration, inform the initiator whether it can execute the corresponding parameter adjustment operation, when to end the parameter adjustment operation, etc. To reduce signaling interactions during parameter adjustment and avoid issues such as data packet loss and reduced transmission efficiency due to the responder's inability to perform parameter adjustment operations in a timely manner, at least one of the following interaction methods shown in the embodiments of this application can be used (the order of description does not represent the superiority or inferiority of the interaction methods).

[0140] Interaction Method 1: Notification.

[0141] Interaction Method Two: Negotiation.

[0142] Notification involves the initiator informing the responder that a parameter adjustment operation needs to be performed, and the responder, upon receiving the notification frame from the initiator, should adjust the operation parameters accordingly. Negotiation involves the initiator requesting the responder to perform a parameter adjustment operation, and the responder, based on its own capabilities and configuration, negotiating with the initiator which parameters can be adjusted and which cannot, thus arriving at an adjustment plan for the operation parameters agreed upon by both the initiator and the responder. The following section describes the interaction process and content for these two interaction methods, using a second device and a first device as examples.

[0143] Interaction Method 1: Notification.

[0144] In the notification interaction method, the responder (second device or first device) can inform the initiator (first device or second device) in advance whether it supports adjusting operating parameters, the range of adjustment, etc. Alternatively, this advance notification process can be skipped, and the initiator (second device or first device) can directly notify the responder (first device or second device) how to adjust the operating parameters when it needs to perform the parameter adjustment operation. These two notification methods will be described in detail below.

[0145] (1) No prior notification process.

[0146] In some embodiments, the first frame is sent from the first device to the second device; or, the first frame is sent from the second device to the first device.

[0147] ·Scenario 1.

[0148] ① Actions on the first equipment side.

[0149] In some embodiments, the first device sends a first frame to the second device, i.e., the first frame is sent by the first device. If a conversion timeout period is reached at a first time, the first device adjusts operating parameters related to a first operating mode in one or more sites affiliated with the first device based on the first frame; wherein the first time begins at a first moment, and the first moment is related to the acknowledgment frame of the first frame. The acknowledgment frame of the first frame refers to the acknowledgment frame sent by the second device to the first device after the second device receives the first frame sent by the first device. This acknowledgment frame is used to indicate that the second device has received the first frame sent by the first device.

[0150] In some embodiments, the conversion timeout is agreed upon by the protocol; or, the conversion timeout is pre-configured.

[0151] In some embodiments, reaching the conversion timeout at the first time can be understood as either the first time being equal to the conversion timeout, or the first time being greater than the conversion timeout. That is, for the first device, the moment when the operating parameters related to the first operating mode are adjusted based on the first frame can be either the moment when the first time is equal to the conversion timeout, or the moment when the first time exceeds the conversion timeout. The unit of this moment can be nanoseconds, microseconds, milliseconds, seconds, etc., and this application embodiment does not limit it in this way.

[0152] In some embodiments, the first moment is related to the acknowledgment frame of the first frame. For example, the first moment is the end of the PPDU carrying the acknowledgment frame; or, the first moment is the end of the signal extension following the PPDU carrying the acknowledgment frame. Alternatively, the first moment is the end of the PPDU carrying the acknowledgment frame of the first frame; or, the first moment is the end of the signal extension following the PPDU carrying the acknowledgment frame of the first frame. The aforementioned PPDU occupies certain resources in both the time and frequency domains. The end of the aforementioned PPDU can be understood as the end of the time domain resources occupied by the PPDU, and the end of the signal extension following the PPDU can be understood as the end of the time domain resources occupied by the signal extension following the PPDU. Alternatively, the end of the aforementioned PPDU can be understood as the end time of the PPDU, and the end of the signal extension following the PPDU can be understood as the end time of the signal extension following the PPDU. Furthermore, the end of the aforementioned PPDU can be understood as the end time of the first device receiving the PPDU, and the end of the signal extension following the PPDU can be understood as the end time of the first device receiving the PPDU.

[0153] Optionally, the signal extension after the PPDU is used to provide the receiver with more processing time to parse the PPDU. The aforementioned signal extension after the PPDU can also be replaced by other equivalent terms such as padding after the PPDU or packet extension after the PPDU. In some embodiments, the signal extension after the PPDU may also be considered part of the PPDU, depending on the definition of the PPDU. This application does not limit this, but the scope of protection of this application is not limited thereto.

[0154] In some embodiments, the confirmation frame in the first frame is used to assist in confirming the adjustment time of the first device and / or the second device, whereby the adjustment time is the time when the operating parameters are adjusted. This adjustment time can refer to the time when the first device instructs one or more sites attached to it to adjust, or it can be the time when one or more sites attached to the first device formally adjust the operating parameters.

[0155] ② Actions on the second equipment side.

[0156] In some embodiments, for the second device, the first frame is received by the second device, and before the second time reaches the conversion timeout period, the second device adjusts the operating parameters related to the first operating mode in one or more sites attached to the second device based on the first frame; or, if the second time reaches the conversion timeout period, the operating parameters related to the first operating mode in one or more sites attached to the second device are adjusted based on the first frame; wherein the second time begins at the first moment, and the first moment is related to the acknowledgment frame of the first frame.

[0157] In some embodiments, before the conversion timeout period is reached at the second time, the second device adjusts the operating parameters related to the first operating mode in one or more sites attached to the second device based on the first frame. This can be understood as: at any time before the conversion timeout period is reached at the second time, the second device adjusts the operating parameters related to the first operating mode in one or more sites attached to the second device based on the first frame. That is, the timing of the second device adjusting the operating parameters related to the first operating mode in one or more sites attached to the second device based on the first frame only needs to ensure that it is before the conversion timeout period is reached at the second time.

[0158] In some embodiments, the second time reaching the conversion timeout can be understood as the second time being equal to the conversion timeout, or the second time being greater than the conversion timeout. Refer to the above description of the first time reaching the conversion timeout; it will not be repeated here.

[0159] In some embodiments, the second time also begins at the first time. For example, the first time is the end of the PPDU carrying the acknowledgment frame; or, the first time is the end of the signal extension following the PPDU carrying the acknowledgment frame. Alternatively, the first time is the end of the PPDU carrying the acknowledgment frame of the first frame; or, the first time is the end of the signal extension following the PPDU carrying the acknowledgment frame of the first frame. For the second device, the first time can also be understood as the end time when the second device sends the PPDU carrying the acknowledgment frame of the first frame, or the end time of the signal extension following the PPDU carrying the acknowledgment frame of the first frame. It can also be said that it is the moment when the second device ends sending the PPDU carrying the first frame, or the end time of the signal extension following the PPDU carrying the acknowledgment frame of the first frame.

[0160] In some embodiments, for the first device and / or the second device, no data transmission will occur from the first moment until the first and / or second time periods after the adjustment of the operating parameters are completed. That is, for the first device and / or the second device, both parties explicitly agree that the original operating parameters are unreliable from the first moment, or that the original operating parameters are likely to cause data packet loss. After the conversion timeout period begins from the first moment, it means that the adjusted operating parameters should be used to send and receive data packets; that is, after the conversion timeout period begins from the first moment, it is considered that the first device and the second device have completed the adjustment of the operating parameters.

[0161] It should be noted that the interaction process in scenario one described above is illustrated by the example of the first device sending the first frame and the second device receiving the first frame. That is, the first device, based on its own capabilities, environment, and currently executing services, determines that it should adjust the operating parameters related to the first operating mode to adapt to the aforementioned requirements. Then, the first device notifies the second device to perform the adjustment of the operating parameters related to the first operating mode to ensure communication between the first and second devices. However, it is also possible that the second device, based on its own capabilities, environment, and currently executing services, determines that the first device should adjust the operating parameters related to the first operating mode to adapt to the aforementioned requirements. Then, the second device notifies the first device to perform the adjustment of the operating parameters related to the first operating mode; that is, the second device sends the first frame, and the first device receives the first frame. In other words, in some embodiments, the first device receives the first frame sent by the second device; that is, the first frame is received by the first device. Optionally, before the conversion timeout period is reached at the second time, the first device adjusts the operating parameters related to the first operating mode in one or more sites attached to the first device based on the first frame; or, if the conversion timeout period is reached at the second time, the first device adjusts the operating parameters related to the first operating mode in one or more sites attached to the first device based on the first frame; wherein the second time begins at the first moment, and the first moment is related to the acknowledgment frame of the first frame. The acknowledgment frame of the first frame is sent by the first device to the second device.

[0162] In some embodiments, the second device sends a first frame to the first device, i.e., the first frame is sent by the second device. If a conversion timeout period is reached at a first time, operating parameters related to a first operating mode in one or more sites affiliated with the second device are adjusted based on the first frame; wherein the first time begins at a first moment, and the first moment is related to the acknowledgment frame of the first frame. The acknowledgment frame of the first frame is sent by the first device to the second device.

[0163] It should be noted that, under normal circumstances, the sending device of the first frame is the first device, and the receiving device of the first frame is the second device. For example, when a non-AP MLD sends the first frame to an AP MLD, the non-AP MLD is the first device, and the AP MLD is the second device. The first frame is used to indicate at least one of the following: enabling a first restricted operating mode for one or more sites attached to the non-AP MLD; disabling the first restricted operating mode for one or more sites attached to the non-AP MLD; adjusting or updating the first restricted operating mode for one or more sites attached to the non-AP MLD. As another example, when an AP MLD sends the first frame to a non-AP MLD, the AP MLD is the first device, and the non-AP MLD is the second device. The first frame is used to indicate at least one of the following: enabling a first restricted operating mode for one or more sites attached to the AP MLD; disabling the first restricted operating mode for one or more sites attached to the AP MLD; adjusting or updating the first restricted operating mode for one or more sites attached to the AP MLD.

[0164] In some embodiments, the first moment is the end of the PPDU carrying the acknowledgment frame; or, the first moment is the end of the signal extension following the PPDU carrying the acknowledgment frame. Alternatively, the first moment is the end of the PPDU carrying the acknowledgment frame of the first frame; or, the first moment is the end of the signal extension following the PPDU carrying the acknowledgment frame of the first frame. It can also be said that the first moment is the end time of the PPDU carrying the acknowledgment frame of the first frame; or, the first moment is the end time of the signal extension following the PPDU carrying the acknowledgment frame of the first frame. Alternatively, for the first device, the first moment is the end time of sending the PPDU carrying the acknowledgment frame of the first frame; or, the first moment is the signal following the PPDU carrying the acknowledgment frame of the first frame. For the second device, the first moment is the end time of receiving the PPDU carrying the acknowledgment frame of the first frame; or, the first moment is the signal following the PPDU carrying the acknowledgment frame of the first frame. Furthermore, for the first device, the first moment is the moment when the transmission of the PPDU carrying the acknowledgment frame of the first frame ends; or, the first moment is the moment when the information extension following the PPDU carrying the acknowledgment frame of the first frame ends. For the second device, the first moment is the moment when it ends receiving the PPDU carrying the acknowledgment frame of the first frame; or, the first moment is the moment when it ends receiving the information extension after receiving the PPDU carrying the acknowledgment frame of the first frame.

[0165] In summary, the method provided in this application illustrates a method for determining the adjustment time of operating parameters based on a conversion timeout. By using the conversion timeout, the first device and the second device can adjust the parameters at the time point when the conversion timeout is reached. This avoids transmission failures and conflicts caused by untimely adjustment of operating parameters, thus improving communication efficiency and reliability.

[0166] ·Scenario 2.

[0167] ① Actions on the first equipment side.

[0168] In some embodiments, the first device sends a first frame to the second device, i.e., the first frame is sent by the first device. The first device receives a second frame sent by the second device, the second frame being used in response to the first frame; sends an acknowledgment frame for the second frame to the second device; and at a second time, based on the first frame, adjusts operating parameters related to a first operating mode in one or more sites attached to the first device, the second time relating to the acknowledgment frame for the second frame.

[0169] In some embodiments, the second frame is used in response to the first frame; it can also be understood as the second frame instructing the second device to adjust operating parameters related to the first operating mode; it can also be understood as the second frame instructing the second device to agree to adjust operating parameters related to the first operating mode; or it can be understood as the second frame instructing one or more sites attached to the second device to adjust operating parameters related to the first operating mode; or it can be said that the second frame instructs one or more sites attached to the second device to agree to adjust operating parameters related to the first operating mode.

[0170] In some embodiments, after sending the first frame, the first device waits for a second frame to be sent by the second device. The second frame is used to indicate that the second device will adjust the operating parameters related to the first operating mode; that is, it can be understood as the second frame indicating that the second device has received the adjustment notification of the operating parameters sent by the first device and is ready to adjust the operating parameters; it can also be understood as the second frame indicating the start time of adjusting the operating parameters related to the first operating mode.

[0171] In some embodiments, the acknowledgment frame of the second frame sent by the first device is used to indicate to the second device that the first device has received the second frame; or, the second frame sent by the first device is used to indicate the adjustment time of the first device and / or the second device, the adjustment time being the time when the operating parameters are adjusted. In some embodiments, the second time is the end of the PPDU carrying the acknowledgment frame; or, the second time is the end of the signal extension following the PPDU carrying the acknowledgment frame. Alternatively, the second time can be described as the end of the PPDU carrying the acknowledgment frame; or, the second time is the end of the signal extension following the PPDU carrying the acknowledgment frame. It can also be described as the end time of the PPDU carrying the acknowledgment frame; or, the second time is the end time of the signal extension following the PPDU carrying the acknowledgment frame. Or, the second time is the end time of sending the PPDU carrying the acknowledgment frame; or, the second time is the signal after sending the PPDU carrying the acknowledgment frame. Furthermore, the second time can be described as the end time of sending the PPDU carrying the acknowledgment frame; or, the second time is the end time of the information extension following the PPDU carrying the acknowledgment frame.

[0172] In some embodiments, the signal extension following the PPDU carrying the acknowledgment frame of the second frame can refer to the signal extension following the PPDU carrying the acknowledgment frame of the first frame described above, and will not be repeated here.

[0173] In some embodiments, the first frame and the second frame are frames of the same type; and / or, the second frame carries the same operating parameters as the first frame; or, the second frame carries a first parameter, which indicates that the second device has confirmed that it will adjust the operating parameters related to the first operating mode. Wherein, if the second frame carries the same operating parameters as the first frame, when the first device receives the second frame, it can also determine, based on the operating parameters carried in the second frame, whether there are data offsets, incorrect parsing, or data loss caused by interference during the transmission of the first and second frames, thereby ensuring the accuracy of the operating parameters during the adjustment process, and thus ensuring the communication efficiency between the first and second devices.

[0174] In some embodiments, when the second frame carries the same operating parameters as the first frame, adjusting the operating parameters related to the first operating mode based on the first frame can be understood as adjusting the operating parameters related to the first operating mode based on the second frame.

[0175] ② Actions on the second equipment side.

[0176] In some embodiments, the second device receives a first frame sent by the first device, i.e., the first frame is received by the second device. Optionally, the second device sends a second frame to the first device, the second frame being used in response to the first frame; receives an acknowledgment frame from the first device for the second frame; and at a second moment, based on the first frame, adjusts operating parameters related to the first operating mode in one or more sites attached to the second device, the second moment being related to the acknowledgment frame of the second frame. In some embodiments, the relevant meaning of the second frame can be referred to in "① Actions on the First Device Side" above.

[0177] In some embodiments, after receiving the first frame sent by the first device, the second device first sends an acknowledgment frame to the first device, indicating that the second device has received the notification from the first device. However, since the second device needs some processing time to schedule the current transmission to provide the first device with the adjusted operating parameters, after confirming that it can provide services to the first device, the second device sends a second frame to the first device. This second frame serves as a response frame from the second device to the first frame, informing the first device that the second device is ready to adjust the operating parameters and can begin parameter adjustment. In other words, the second frame indicates to the first device that the second device is ready to provide services to the first device.

[0178] In some embodiments, after receiving an acknowledgment frame from the first device for the second frame, the second device can determine that both parties are ready to adjust the operating parameters. Therefore, at the second moment, it adjusts the operating parameters related to the first operating mode in one or more sites attached to the second device based on the first frame.

[0179] In some embodiments, the second time is the end of the PPDU carrying the acknowledgment frame; or, the second time is the end of the signal extension following the PPDU carrying the acknowledgment frame. Alternatively, the second time can be described as the end of the PPDU carrying the acknowledgment frame of the second frame; or, the second time is the end of the signal extension following the PPDU carrying the acknowledgment frame of the second frame. It can also be described as the end time of the PPDU carrying the acknowledgment frame of the second frame; or, the second time is the end time of the signal extension following the PPDU carrying the acknowledgment frame of the second frame. Or, the second time is the end time of receiving the PPDU carrying the acknowledgment frame of the second frame; or, the second time is the time after receiving the signal following the PPDU carrying the acknowledgment frame of the second frame. Furthermore, the second time can be described as the time when the reception of the PPDU carrying the acknowledgment frame of the second frame ends; or, the second time is the time when the information extension following the reception of the PPDU carrying the acknowledgment frame of the second frame ends.

[0180] In some embodiments, the signal extension following the PPDU carrying the acknowledgment frame of the second frame can refer to the signal extension following the PPDU carrying the acknowledgment frame of the first frame described above, and will not be repeated here.

[0181] In some embodiments, the first frame and the second frame are frames of the same type; and / or, the second frame carries the same operating parameters as the first frame. In this case, adjusting the operating parameters related to the first operating mode based on the first frame can also be understood as adjusting the operating parameters related to the first operating mode based on the second frame. Alternatively, the second frame carries a first parameter indicating that the second device has confirmed that it will adjust the operating parameters related to the first operating mode. Frames of the same type refer to frames with the same structure and / or function.

[0182] It should be noted that the interaction process in the above scenario two is illustrated by the example of the first device sending the first frame and the second device receiving the first frame. That is, the first device, based on its own capabilities, environment, and currently executed services, determines that it should adjust the operating parameters related to the first operating mode to adapt to the above requirements. Then, the first device notifies the second device to perform the adjustment of the operating parameters related to the first operating mode to ensure communication between the first and second devices. However, it is also possible that the second device, based on its own capabilities, environment, and currently executed services, determines that the first device should adjust the operating parameters related to the first operating mode to adapt to the above requirements. Then, the second device notifies the first device to perform the adjustment of the operating parameters related to the first operating mode. That is, the second device sends the first frame and the first device receives the first frame.

[0183] In some embodiments, the first device receives a first frame sent by the second device, i.e., the first frame is received by the first device. Optionally, the first device sends a second frame to the second device, the second frame being used in response to the first frame; receives an acknowledgment frame from the second device for the second frame; and at a second moment, based on the first frame, adjusts operating parameters related to a first operating mode in one or more sites attached to the first device, the second moment relating to the acknowledgment frame of the second frame.

[0184] In some embodiments, the second device sends a first frame to the first device, i.e., the first frame is sent by the second device. Optionally, the second device receives a second frame sent by the first device, the second frame being used in response to the first frame; sends an acknowledgment frame to the first device for the second frame; and at a second moment, based on the first frame, adjusts operating parameters related to a first operating mode in one or more sites attached to the first device, the second moment relating to the acknowledgment frame of the second frame.

[0185] It should be noted that, under normal circumstances, the sending device of the first frame is the first device, and the receiving device of the first frame is the second device. For example, when a non-AP MLD sends the first frame to an AP MLD, the non-AP MLD is the first device, and the AP MLD is the second device. The first frame is used to indicate at least one of the following: enabling a first restricted operating mode for one or more sites attached to the non-AP MLD; disabling the first restricted operating mode for one or more sites attached to the non-AP MLD; adjusting or updating the first restricted operating mode for one or more sites attached to the non-AP MLD. As another example, when an AP MLD sends the first frame to a non-AP MLD, the AP MLD is the first device, and the non-AP MLD is the second device. The first frame is used to indicate at least one of the following: enabling a first restricted operating mode for one or more sites attached to the AP MLD; disabling the first restricted operating mode for one or more sites attached to the AP MLD; adjusting or updating the first restricted operating mode for one or more sites attached to the AP MLD.

[0186] In some embodiments, the definition of the second moment can be referred to the specific description in Situation 2 above, and will not be repeated here.

[0187] In summary, the method provided in this application illustrates a method for determining the adjustment time of operation parameters based on a second frame. Through the second frame, the responder informs the initiator to confirm the adjustment of the operation parameters. This avoids transmission failures and conflicts caused by untimely adjustment of operation parameters, improving communication efficiency and reliability. Furthermore, it ensures that the initiator and responder agree on the adjustment of the operation parameters, avoiding data anomalies caused by interference during transmission, which could lead to abnormal parameter adjustments.

[0188] It should be noted that Scenarios 1 and 2 described above can be implemented as independent embodiments or as combined embodiments. That is, only a conversion timeout is set, and the first and second devices should adjust the operating parameters when the conversion timeout is reached in the first time; or, it is agreed that the adjustment time is confirmed based on the second frame, i.e., the first and second devices confirm the second time based on the confirmation frame for the second frame, and adjust the operating parameters in the second time. However, in some optional embodiments, Scenarios 1 and 2 can be implemented in combination, i.e., both a conversion timeout is set and it is agreed that a second frame can be sent to confirm the adjustment time. Specifically, the first device and / or the second device adjust the operating parameters related to the first operating mode in a third time, based on the first frame. The third time is the earlier of the first time when the conversion timeout is reached and the second time.

[0189] That is, for the first device, there are two scenarios: If, before the first timeout period arrives, no second frame is received, no second frame is sent, no acknowledgment frame for the second frame is received, or no acknowledgment frame for the second frame is sent, and the first timeout period arrives, the operating parameters related to the first operating mode in one or more stations attached to the first device are adjusted based on the first frame. If, before the first timeout period arrives, a second frame is received, a second frame is sent, a acknowledgment frame for the second frame is received, or an acknowledgment frame for the second frame is sent, a second timeout period is determined; and at the second timeout period, based on the first frame, the operating parameters related to the first operating mode in one or more stations attached to the first device are adjusted. In this case, the time between the first timeout period and the second timeout period is less than the conversion timeout period, meaning the second timeout period is the time before the first timeout period arrives.

[0190] For the second device, there are two scenarios: If, before the first conversion timeout period is reached, no second frame is received, no second frame is sent, no acknowledgment frame for the second frame is received, or no acknowledgment frame for the second frame is sent, and the first conversion timeout period is reached, then based on the first frame, the operating parameters related to the first operating mode in one or more stations attached to the second device are adjusted. Alternatively, if, before the first conversion timeout period is reached, a second frame is received, a second frame is sent, a acknowledgment frame for the second frame is received, or an acknowledgment frame for the second frame is sent, a second moment is determined; and at the second moment, based on the first frame, the operating parameters related to the first operating mode in one or more stations attached to the second device are adjusted. In this case, the time between the first moment and the second moment is less than the conversion timeout period, meaning the second moment is the moment before the first conversion timeout period is reached.

[0191] In summary, the method provided in this application takes into account both the conversion timeout and the second frame. On the one hand, when the frame exchange between the first and second frames is completed within the conversion timeout period, parameter adjustments can be performed immediately without waiting for a longer time, thus improving the efficiency of parameter adjustment. On the other hand, the frame exchange time may vary under different network environments or device performance conditions. By setting a conversion timeout, these changes can be flexibly adapted to, and the strategy can be adjusted in a timely manner to ensure that parameter adjustments can be performed normally under various conditions.

[0192] (2) There was a prior notification process.

[0193] In some embodiments, the first device receives a third frame, which is used to indicate whether the second device allows the first device to adjust the operating parameters of one or more sites attached to the first device in relation to a first operating mode.

[0194] In some embodiments, the second device sends a third frame to the first device, the third frame being used to indicate whether the second device allows the first device to adjust operating parameters related to the first operating mode in one or more sites attached to the first device.

[0195] In some embodiments, the third frame is used to indicate whether the AP MLD allows at least one STA in the non-AP MLD to adjust operating parameters related to the first operating mode; or, the third frame is used to indicate whether the AP MLD allows some STAs in the non-AP MLD to adjust operating parameters related to the first operating mode; or, the third frame is used to indicate which STAs in the non-AP MLD allow the AP MLD to adjust operating parameters related to the first operating mode; or, the third frame is used to indicate which links allow the adjustment of operating parameters related to the first operating mode, where one link corresponds to one AP in the AP MLD and one STA in the non-AP MLD. Here, "some STAs" refers to some STAs among at least one STA, or some STAs in the non-AP MLD; that is, the third frame does not indicate whether all STAs in the non-AP MLD are allowed to adjust operating parameters related to the first operating mode.

[0196] In some embodiments, after receiving the third frame, the first device transmits the third frame to other STAs belonging to the same non-AP MLD as the first device through the MAC layer, application layer, or other network layer.

[0197] In some embodiments, the third frame is further used to indicate whether the operation parameters can be adjusted in one or more sites attached to the first device; and / or, the third frame is further used to indicate the adjustment range of the operation parameters. The indication in the third frame regarding whether the operation parameters can be adjusted and the adjustment range of the operation parameters may be set for all sites in the one or more sites attached to the first device, or it may be set for some sites in the one or more sites attached to the first device. That is, in some embodiments, the third frame also indicates one or more sites attached to the first device. These one or more sites may be the sites where the first device wants to adjust the operation parameters, or they may include the sites where the first device wants to adjust the operation parameters, or they may be a portion of the sites where the first device wants to adjust the operation parameters. This application does not limit this specific to any particular site. For example, when the third frame is used to indicate that the second device allows the first device to adjust the operating parameters related to the first operating mode in one or more sites attached to the first device, the third frame may also be used to indicate the operating parameters that can be adjusted in one or more sites attached to the first device; or, when the third frame is used to indicate that the second device allows the first device to adjust the operating parameters related to the first operating mode in one or more sites attached to the first device, the third frame may also be used to indicate the operating parameters that can be adjusted and the adjustment range of the operating parameters that can be adjusted (which may also be referred to as the value range of the operating parameters); or, when the third frame is used to indicate that the second device allows the first device to adjust the operating parameters related to the first operating mode in one or more sites attached to the first device, the third frame may also be used to indicate the adjustment range of the operating parameters related to the first operating mode.

[0198] In some embodiments, the third frame is further used to indicate the operating parameters that each STA in at least one STA in the non-AP MLD is allowed to adjust; and / or, the third frame is further used to indicate the adjustment range of the operating parameters in each STA in at least one STA in the non-AP MLD. Alternatively, the third frame is further used to indicate the operating parameters that each STA in some STAs in the non-AP MLD is allowed to adjust; and / or, the third frame is further used to indicate the adjustment range of the operating parameters in each STA in some STAs in the non-AP MLD. Alternatively, the third frame is further used to indicate the operating parameters that all or some links in at least one link are allowed to adjust; and / or, the third frame is further used to indicate the adjustment range of the operating parameters that all or some links in at least one link are allowed to adjust.

[0199] In some embodiments, when the first device needs to adjust the operating parameters related to the first operating mode, it confirms the first frame based on the adjustable operating parameters indicated by the third frame; or, when the first device needs to adjust the operating parameters related to the first operating mode, it confirms the first frame based on the adjustable parameter range indicated by the third frame. Alternatively, when the second device needs to adjust the operating parameters related to the first operating mode, it confirms the first frame based on the adjustable operating parameters indicated by the third frame; or, when the second device needs to adjust the operating parameters related to the first operating mode, it confirms the first frame based on the adjustable parameter range indicated by the third frame. That is, although the third frame is a restriction imposed by the second device or AP MLD on the first device or non-AP MLD, the restriction of the third frame depends on the capabilities of the second device or AP MLD, meaning that the third frame is actually also a restriction imposed on the second device or AP MLD itself. In this case, it can also be understood that the second device or AP MLD determines the first frame based on its own capabilities.

[0200] In some embodiments, the first device can inform the second device whether it allows adjustment of operating parameters related to a first operating mode in one or more sites affiliated with the first device. Specifically, the first device sends a third frame to the second device, indicating whether the first device allows the second device to adjust the operating parameters related to the first operating mode. The second device receives the third frame.

[0201] In some embodiments, when an advance notification process exists, when the first device or the second device sends a first frame to notify the responder to adjust the operating parameters, it needs to consider whether adjustment is allowed, which operating parameters are allowed to be adjusted, and the adjustment range of the operating parameters as shown in the advance notification process, thereby realizing the adjustment of the operating parameters for the first device and the second device. That is, for the first device, if the third frame indicates that the second device allows the first device to adjust the operating parameters related to the first operating mode, the operating parameters related to the first operating mode are adjusted based on the first frame. For the second device, the operating parameters related to the first operating mode are still adjusted based on the first frame. The specific interaction process of adjusting the operating parameters of the first device and the second device can be referred to the scenarios one and two shown in "(1) No advance notification process" above, and will not be repeated here.

[0202] In summary, the method provided in this application embodiment allows the second device to inform the first device in advance of the operating parameters that can be adjusted and / or the adjustment range of the operating parameters. This avoids errors caused by the second device not supporting the adjustment of the operating parameters when the first device adjusts them, thus avoiding the need to repeatedly adjust the operating parameters through the first frame and resulting in wasted signaling.

[0203] Interaction Method Two: Negotiation.

[0204] In some embodiments, the first device sends a first frame to the second device, the first frame being used to request the second device to adjust operating parameters related to a first operating mode in one or more sites attached to the first device; and receives a fourth frame sent by the second device, the fourth frame being used to indicate whether the second device accepts the request from the first device.

[0205] In some embodiments, the second device receives a first frame, which is used to request the second device to adjust the operating parameters to the operating parameters corresponding to the first operating mode; and sends a fourth frame, which is used to indicate whether the second device accepts one or more parameter adjustment requests from the first device. Optionally, one or more parameter adjustment requests correspond one-to-one with one or more stations attached to the first device, that is, one station attached to the first device corresponds to one parameter adjustment request; or, multiple stations attached to the first device correspond to one parameter adjustment request.

[0206] In some embodiments, the fourth frame is used to indicate whether the second device accepts the parameter adjustment request from the first device; or, the fourth frame is used to indicate whether the AP MLD accepts the request from at least one STA in the non-AP MLD; or, the fourth frame is used to indicate whether the AP MLD accepts the request from each STA in at least one STA in the non-AP MLD; or, the fourth frame is used to indicate whether the AP MLD accepts the request from each STA in a subset of the non-AP MLD; or, the fourth frame is used to indicate whether the AP MLD supports parameter adjustment for each link in at least one link; or, the fourth frame is used to indicate whether the AP MLD supports parameter adjustment for a subset of links in at least one link.

[0207] In some embodiments, the first frame can be understood as a request frame, and the fourth frame is a response frame to the first frame. The first frame carries the operating parameters that the first device expects to adjust, as well as the adjusted parameter values. If the fourth frame indicates that the request from the first device is accepted, the first device adjusts the operating parameters related to the first operating mode based on the first frame.

[0208] In some embodiments, if the second device indicates acceptance of the first device's request in the fourth frame, the second device adjusts the operating parameters related to the first operating mode in one or more sites attached to the second device based on the first frame.

[0209] In some embodiments, the fourth frame is further used to indicate that the second device refuses to adjust the operating parameters; or, the fourth frame is further used to indicate that the second device allows the adjustment of the operating parameters. That is, the fourth frame is also used to indicate the reason why the second device refuses the request of the first device, which can be understood as the fourth frame indicating which part of the operating parameters is being adjusted and thus the first device's request is being refused. Optionally, the fourth frame shows the parameters that are refused adjustment in response to each parameter adjustment request, which can be understood as the fourth frame including one or more parameter adjustment responses, each parameter adjustment response indicating whether the corresponding parameter adjustment request is accepted; and / or, each parameter adjustment response indicating the operating parameters in the corresponding parameter adjustment request that are refused adjustment; and / or, each parameter adjustment response indicating the operating parameters in the corresponding parameter adjustment request that are allowed adjustment.

[0210] In summary, the method provided in this application embodiment adjusts the operating parameters through negotiation, thereby dynamically adjusting the operating parameters according to the current network environment and business needs, coordinating the operating rules of the site entering the first operating mode and the peer site serving that site, avoiding conflicts and unnecessary signaling interactions caused by parameter adjustment, and avoiding or reducing the complexity of scheduling and response for the site serving the site in the first operating mode.

[0211] 4. Application scenarios for parameter adjustment.

[0212] In some embodiments, the application scenarios corresponding to adjusting the operating parameters related to the first operating mode include at least one of enabling the first operating mode, disabling the first operating mode, and further adjusting the operating parameters in the first operating mode. These application scenarios will be described in detail below.

[0213] • Enable the first operating mode.

[0214] In some embodiments, the first frame is used to indicate enabling a first operating mode; based on the first frame, the first device (and / or the second device) adjusts the operating parameters related to the first operating mode in one or more sites attached to the first device (and / or one or more sites attached to the second device) to the first operating parameters corresponding to the first operating mode. The first operating parameters corresponding to each site may be the same or different.

[0215] In some embodiments, the first frame is used to indicate enabling a first operating mode; or, the first frame is used to indicate entering the first operating mode; or, the first frame is used to indicate switching from a second operating mode to the first operating mode, where the second operating mode is the current operating mode; or, the first frame is used to indicate switching to the first operating mode. Optionally, the second operating mode may be an unrestricted operating mode, or a normal operating mode, or an operating mode unrelated to coexisting operations, or an operating mode in an undisturbed scenario, etc.

[0216] In some embodiments, the first operation parameter corresponding to the first operation mode is carried by the first frame; or, the first operation parameter corresponding to the first operation mode is agreed upon in advance by the first device and the second device; or, the first operation parameter corresponding to the first operation mode is agreed upon in advance by the protocol; or, the first operation parameter corresponding to the first operation mode is pre-configured between the first device and the second device.

[0217] • Further adjust the operating parameters in the first operating mode.

[0218] In some embodiments, the first frame is used to instruct the adjustment of a first operating parameter corresponding to a first operating mode; based on the first frame, the first device (and / or the second device) adjusts the operating parameters related to the first operating mode in one or more sites attached to the first device (and / or one or more sites attached to the second device) from the first operating parameter corresponding to the first operating mode to a second operating parameter corresponding to the first operating mode. The second operating parameter corresponding to each site may be the same or different.

[0219] In some embodiments, the first frame is used to indicate adjusting the first operating parameter corresponding to the first operating mode; or, the first frame is used to indicate adjusting the operating parameter to the second operating parameter corresponding to the first operating mode.

[0220] In some embodiments, the second operation parameter corresponding to the first operation mode is carried by the first frame; or, the second operation parameter corresponding to the first operation mode is pre-agreed upon by the first device and the second device; or, the second operation parameter corresponding to the first operation mode is pre-agreed upon by the protocol; or, the second operation parameter corresponding to the first operation mode is pre-configured between the first device and the second device.

[0221] • First operating mode not enabled.

[0222] In some embodiments, the first frame is used to indicate that a first operating mode is disabled; based on the first frame, the first device (and / or the second device) adjusts the operating parameters associated with the first operating mode in one or more sites attached to the first device (and / or one or more sites attached to the second device) to third operating parameters corresponding to the second operating mode. The third operating parameters for each site may be the same or different.

[0223] In some embodiments, the first frame is used to indicate that the first operating mode is disabled; or, the first frame is used to indicate exiting the first operating mode; or, the first frame is used to indicate switching from the first operating mode to the second operating mode; or, the first frame is used to indicate switching to the first operating mode. The second operating mode may be an unrestricted operating mode, or a normal operating mode, or an operating mode unrelated to coexistence operations, or an operating mode in an undisturbed scenario, or an operating mode before entering the restricted operating mode, etc.

[0224] In some embodiments, the third operation parameter corresponding to the second operation mode is carried by the first frame; or, the third operation parameter corresponding to the second operation mode is agreed upon in advance by the first device and the second device; or, the third operation parameter corresponding to the second operation mode is agreed upon in advance by the protocol; or, the third operation parameter corresponding to the second operation mode is pre-configured between the first device and the second device; or, the third operation parameter corresponding to the second operation mode is the operation parameter before enabling the first operation mode.

[0225] In some embodiments, when the first operating mode is not enabled, in addition to indicating the first operating mode is not enabled via a first frame, the first device (and / or the second device) may automatically exit the first operating mode. For example, the duration is determined when or before enabling the first operating mode. If the first frame includes a duration indicating the duration of time the device is in the first operating mode at one or more sites associated with it (or one or more sites associated with the second device); then, if the first device (or the second device) reaches the duration in a third time, it adjusts the operating parameters to the operating parameters corresponding to the second operating modulus (such as the third operating parameters described above), with the third time beginning at the adjustment time of the operating parameters related to the first operating mode. That is, if the duration of time in the first operating mode reaches the duration, the first device and / or the second device automatically exit the first operating mode and enter the second operating mode.

[0226] In summary, the method provided in this application illustrates three application scenarios based on the first frame. By using the first frame, transmission failures and conflicts caused by untimely adjustment of operating parameters are avoided, improving communication efficiency and reliability. Furthermore, adjusting operating parameters using the first frame causes the first or second device to enter or exit a first operating mode. This first operating mode is at least one of the following: a restricted operating mode, a receive capability adjustment operating mode, a transmit capability adjustment operating mode, a transmit / receive capability adjustment operating mode, an operating mode related to coexistence operation, and an operating mode under interference scenarios. Entering the first operating mode can avoid coexistence interference caused by multiple links working simultaneously or multiple links having strong signals, thus affecting signal quality and data transmission reliability. In other words, even if the first or second device enters the first operating mode, this coexistence interference is effectively reduced, improving the stability and performance of data transmission. At other times when coexistence interference does not occur, the first frame can be used to cause the first or second device to exit the first operating mode, thereby improving link utilization and data transmission efficiency.

[0227] 5. Frame structure during parameter adjustment.

[0228] Next, we will introduce the frame structures that were swapped during the parameter adjustment process, namely the frame structures of the first frame, the second frame, the third frame, and the fourth frame.

[0229] In some embodiments, the first frame, the second frame, or the third frame includes an operation parameter field, which indicates the adjusted operation parameters.

[0230] In some embodiments, the operation parameter field is used to indicate the adjusted operation parameter; it can be understood that the operation parameter field is used to indicate the parameter value of the adjusted operation parameter; it can also be understood that the operation parameter field is used to indicate the operation parameter that needs to be adjusted; or, the operation parameter field is used to indicate the index value of the adjusted operation parameter.

[0231] For example, if the first device and the second device pre-agree, pre-configure, or pre-negotiate the parameter values ​​corresponding to different operating modes, for instance, it is pre-agreed that in the first operating mode, the first value of operation parameter 1, the first value of operation parameter 2, and the first value of operation parameter 3 can be used corresponding to index value 0, and the second value of operation parameter 1, the second value of operation parameter 2, and the second value of operation parameter 3 can be used corresponding to index value 1. In the second operating mode, the third value of operation parameter 1, the third value of operation parameter 2, and the third value of operation parameter 3 can be used corresponding to index value 2. Then, in the first frame, the index value can be used to indicate the adjustment of the operating parameters. If the operating parameter field carried in the first frame is 0, it indicates that the adjusted operating parameters are {the first value of operation parameter 1, the first value of operation parameter 2, and the first value of operation parameter 3}, and so on.

[0232] In some embodiments, the operation parameter field includes at least one of the following subfields: a maximum PPDU duration received subfield, which indicates the maximum PPDU duration supported at reception in one or more sites attached to the first device (and / or one or more sites attached to the second device); a maximum PPDU duration transmitted subfield, which indicates the maximum PPDU duration supported at transmission in one or more sites attached to the first device (and / or one or more sites attached to the second device); and a maximum MCS received subfield, which indicates the maximum PPDU duration supported at reception in one or more sites attached to the first device (and / or one or more sites attached to the second device); and a maximum MCS received subfield, which indicates the maximum PPDU duration supported at reception in one or more sites attached to the first device (and / or one or more sites attached to the second device). The maximum MCS supported at reception in one or more sites (and / or one or more sites attached to the second device); the maximum MCS to transmit subfield, which indicates the maximum MCS supported at transmission in one or more sites attached to the first device (and / or one or more sites attached to the second device); the LDPC mode subfield, which indicates whether LDPC is supported at transmission and / or reception in one or more sites attached to the first device (and / or one or more sites attached to the second device); the HT Immediate BA mode subfield, which indicates whether the HT-Immediate BA protocol is active or suspended; and the disabled subchannel bitmap subfield, which indicates whether each subchannel in at least one subchannel within the BSS bandwidth is enabled or disabled.

[0233] In some embodiments, the Maximum PPDU Length Received subfield is used to indicate the maximum PPDU duration supported during reception at one or more sites attached to the first device (and / or one or more sites attached to the second device). For example, in a scenario where the first operating mode is enabled, the Maximum PPDU Length Received subfield indicates the maximum PPDU duration supported by the STA during reception when the STA is in the first operating mode, in microseconds.

[0234] In some embodiments, the maximum PPDU duration subfield is used to indicate the maximum PPDU duration supported during transmission in one or more sites attached to the first device (and / or one or more sites attached to the second device). For example, in a scenario where the first operating mode is enabled, the maximum PPDU duration subfield indicates the maximum PPDU duration supported by the STA during transmission when the STA is in the first operating mode, in microseconds.

[0235] In some embodiments, the transmit maximum MCS subfield is used to indicate the maximum MCS supported during transmission in one or more sites attached to the first device (and / or one or more sites attached to the second device). For example, in a scenario where a first operating mode is enabled, the transmit maximum MCS subfield indicates the maximum MCS supported by the STA during transmission when the STA is in the first operating mode, wherein the subfield contains an unsigned integer from 0 to 9 representing the maximum MCS index value. Specifically, the MCS index value corresponds to the modulation and coding used in the data field of the PPDU. For instance, if the transmit maximum MCS subfield indicates a maximum MCS index value of 8 (i.e., corresponding to 256-QAM modulation, 3 / 4 code rate), it indicates that the maximum order modulation supported by the STA during transmission is 256-QAM, corresponding to a code rate of 3 / 4.

[0236] In some embodiments, the Receive Maximum MCS subfield is used to indicate the maximum MCS supported at the time of reception among one or more sites attached to the first device (and / or one or more sites attached to the second device). For example, in a scenario where the first operating mode is enabled, the Receive Maximum MCS subfield indicates the maximum MCS supported by the STA at the time of reception when the STA is in the first operating mode. This subfield contains an unsigned integer from 0 to 9, representing the maximum MCS index value. The specific encoding method can be found in the Send Maximum MCS subfield.

[0237] In some embodiments, the LDPC mode subfield is used to indicate whether LDPC is supported in transmission and / or reception at one or more sites attached to the first device (and / or one or more sites attached to the second device). For example, in a scenario where a first operating mode is enabled, the LDPC mode subfield indicates whether the STA supports LDPC in transmission and / or reception when the STA is in the first operating mode. For instance, a value of 1 for the LDPC mode subfield indicates that the STA supports LDPC in transmission and / or reception; otherwise, it is set to 0.

[0238] In some embodiments, the HT Immediate Block Acknowledgment (HT-Immediate BA) mode subfield is used to indicate whether the HT-Immediate BA protocol is active or suspended. For example, in a scenario where the first operating mode is enabled, the HT Immediate BA mode subfield indicates whether all HT-Immediate BA protocols are active or suspended when the STA is in the first operating mode. For instance, a value of 1 for the HT Immediate BA mode subfield indicates that all HT-Immediate BA protocols are active when the STA is in the first operating mode; otherwise, it is set to 0. HT Immediate BA (High Throughput Immediate Block Acknowledgment, HT-Immediate BA) is an immediate acknowledgment mechanism that allows the receiver to send a block acknowledgment frame immediately after receiving a data frame, instead of waiting for a period of time. This protocol reduces the number of acknowledgment frames and the corresponding frame interval time, thereby improving channel utilization and network throughput; through immediate acknowledgment, lost data frames can be detected and retransmitted more quickly, improving the reliability of data transmission; it has significant advantages in application scenarios requiring rapid response.

[0239] In some embodiments, the disabled subchannel bitmap subfield is used to indicate whether each subchannel in at least one subchannel within the BSS bandwidth is enabled or disabled. For example, in a scenario where a first operating mode is enabled, the disabled subchannel bitmap subfield indicates whether one or more 20MHz subchannels within the BSS bandwidth are enabled or disabled when the STA user is in the first operating mode. Optionally, the disabled subchannel bitmap subfield is a 16-bit bitmap, where the lowest bit corresponds to a 20MHz subchannel within the BSS bandwidth and is the lowest frequency among all 20MHz subchannels within the BSS bandwidth. Each consecutive bit in the disabled subchannel bitmap corresponds to the next higher frequency 20MHz subchannel. Setting the corresponding bit within the BSS bandwidth range in the disabled subchannel bitmap to 1 indicates that the corresponding 20MHz subchannel is punctured, meaning it is disabled or not used during transmission. Setting the corresponding bit within the BSS bandwidth range in the disabled subchannel bitmap to 0 indicates that the corresponding 20MHz subchannel is not punctured, meaning it is enabled or used during transmission. Bits outside the BSS bandwidth in the disabled subchannel bitmap are reserved. This means that the number of bits in the subfield of the disabled subchannel bitmap can be increased according to the development of communication standards, thereby indicating a wider BSS bandwidth range, i.e., more subchannels.

[0240] In some embodiments, the Ack-Enabled aggregation mode subfield is used to indicate whether receiving an A-MPDU containing at least two frames is supported in one or more sites attached to the first device (and / or one or more sites attached to the second device). The Ack-Enabled aggregation mode subfield indicates whether the STA supports receiving an A-MPDU containing two or more frames, where at least one frame requests an Ack frame or acknowledgment context in a Multi-STA BlockAck frame. It is set to 1 if the STA supports receiving this A-MPDU format; otherwise, it is set to 0. It should be noted that in other embodiments, the "0" and "1" values ​​of the field or element or bit setting may represent the opposite.

[0241] In some embodiments, the Maximum A-MPDU Length Exponent field is used to indicate the maximum length of A-MPDUs that can be sent or received in one or more sites attached to the first device (and / or one or more sites attached to the second device). For example, in a scenario where a first operating mode is enabled, this is the maximum length of A-MPDUs that the STA is allowed to send or receive when the STA is in the first operating mode. The length defined in this field is equal to 2(3 + Maximum A-MPDU Length Exponent) - 1 byte.

[0242] In some embodiments, the Maximum A-MPDU Length Exponential Extension field is used to indicate the maximum exponential extension of the A-MPDU length supported during transmission or reception in one or more sites attached to the first device (and / or one or more sites attached to the second device). For example, in a scenario where a first operating mode is enabled, when the STA is in the first operating mode, this field sets the maximum value of the maximum exponential extension of the A-MPDU length supported by the STA during transmission or reception.

[0243] In some embodiments, the Minimum MPDU Start Spacing field is used to indicate the minimum time interval between adjacent MPDU starts within an A-MPDU that can be transmitted or received in one or more sites attached to the first device (and / or one or more sites attached to the second device). For example, in a scenario where a first operating mode is enabled, the minimum time interval between adjacent MPDU starts within an A-MPDU that the STA can transmit or receive when the STA is in the first operating mode is measured in the PHY SAP.

[0244] In some embodiments, the MPDU MU Spacing Factor subfield is used to calculate the value multiplied by the minimum starting spacing of the MPDU. The minimum starting spacing of the MPDU calculated by this subfield value is the minimum spacing between the start of adjacent MPDUs within an A-MPDU that the STA can send when the STA is in a restricted operating mode. The minimum spacing is represented by the number of bytes (N) between the start of two consecutive MPDUs in the A-MPDU, as measured by the PHY SAP.

[0245] In some embodiments, the minimum spacing between the start of adjacent MPDUs within an A-MPDU that the STA can send in the first operating mode can be represented by one of the fields of the Minimum MPDU Start Spacing field and the MPDU MU Spacing Factor subfield.

[0246] In some embodiments, the TID Aggregation Tx Limit subfield indicates the maximum number of TIDs corresponding to MPDUs that can be aggregated from one or more sites attached to the first device (and / or one or more sites attached to the second device). The value of the TID Aggregation Tx Limit subfield is less than or equal to MT+1, where MT is the value indicated in the Multi-TID Aggregation Tx Support subfield of the HE MAC Capabilities Information field in the HE Capabilities element sent by the STA.

[0247] In some embodiments, the TID Aggregation Rx Limit subfield represents the maximum number of TIDs corresponding to MPDUs that can be aggregated from multiple TID A-MPDUs that can be received in one or more sites attached to the first device (and / or one or more sites attached to the second device). For example, in a scenario where a first operating mode is enabled, when the STA is in the first operating mode, the maximum number of TIDs corresponding to MPDUs that can be aggregated from multiple TID A-MPDUs that the STA can receive. The value of the TID Aggregation Rx Limit subfield is less than or equal to MR+1, where MR is the value indicated in the Multi-TID Aggregation Rx Support subfield of the HE MAC Capabilities Information field in the HE Capabilities element sent by the STA.

[0248] In some embodiments, the fragmentation mode subfield indicates whether fragmentation and / or defragmentation are supported. For example, in a scenario where a first operating mode is enabled, this indicates whether fragmentation and / or defragmentation are supported when the STA is in the first operating mode. Fragmentation refers to the STA's MAC being able to fragment and reassemble the MSDU or MMPDU carried in a separately addressed MPDU.

[0249] In some embodiments, the A-MSDU fragmentation mode field indicates whether sending or receiving fragmented A-MSDUs is supported. For example, in a scenario where the first operating mode is enabled, when the STA is in a restricted operating mode, it indicates whether sending or receiving fragmented A-MSDUs is supported. If the A-MSDU fragmentation mode field is set to 1, it indicates that sending or receiving fragmented A-MSDUs is supported; if it is set to 0, it indicates that sending or receiving fragmented A-MSDUs is not supported.

[0250] In some embodiments, the maximum transmit power subfield represents the total transmit power at the transmit antenna connector of all antennas used to transmit PPDUs in one or more sites attached to the first device (and / or one or more sites attached to the second device). For example, in a scenario where a first operating mode is enabled, when the STA is in the first operating mode, the total transmit power at the transmit antenna connector of all antennas used by the STA to transmit PPDUs, in dBm / 20MHz. The transmit power PTX in dBm / 20MHz is calculated as PTX = -20 + 2 × FVal, where FVal is the value of the maximum transmit power subfield, and 31 is a reserved value.

[0251] In some embodiments, the minimum target received power subfield represents the minimum expected received signal power. For example, in a scenario where a first operating mode is enabled, when the STA is in the first operating mode, the minimum expected received signal power is measured at the STA's antenna connector and averaged across the antenna. The minimum target received power (in dBm) is Targetpwr = -90 + 2 × Fval, where Fval is the value of the minimum target received power subfield. Using the information indicated by the minimum target received power subfield, the restricted operation responder can better adjust the transmit power and select a suitable modulation and coding scheme based on the restricted operation initiator's minimum target received power requirement.

[0252] In some embodiments, the Preferred AC subfield indicates the lowest recommended AC in the MPDU carried in the PPDU that can be sent or received among one or more sites attached to the first device (and / or one or more sites attached to the second device). For example, in a scenario where a first operating mode is enabled, when the STA is in the first operating mode, the STA can send or receive the corresponding lowest recommended AC in the MPDU carried in the PPDU. The encoding of the Preferred AC subfield is shown in Table 1. The information indicated by the Preferred AC subfield enables initiators and responders to better utilize transmission resources for the transmission and scheduling of higher-priority service data.

[0253] Table 1 ACI-to-AC Encoding

[0254] In some embodiments, the first frame, the second frame, or the third frame further includes at least one of the following fields: a duration field, which indicates the duration of time the device is in the first operating mode at one or more sites attached to the first device (and / or one or more sites attached to the second device); an operation parameter presence bitmap field, which indicates the operation parameters present in the operation parameter field; and a permitted operation parameter bitmap field, which indicates the operation parameters that can be adjusted.

[0255] In some embodiments, the duration subfield contains an unsigned integer indicating the duration, in microseconds, of the time the first operating mode is maintained in one or more sites attached to the first device (and / or one or more sites attached to the second device). Specifically, the duration subfield is not present when the first frame indicates that the first operating mode is disabled; it may be present when the first frame indicates that the first operating mode is enabled. The duration subfield is used to indicate the duration the first operating mode is maintained in one or more sites attached to the first device (and / or one or more sites attached to the second device); that is, if the duration of the first operating mode is maintained in one or more sites attached to the first device (and / or one or more sites attached to the second device) from the time the first operating mode is enabled or an adjustment related to the first operating mode is performed reaches the duration specified in the duration subfield, the device will automatically exit the first operating mode or disable the first operating mode without additional signaling indication.

[0256] In some embodiments, the Operation Parameter Presence Bitmap field is used to indicate the operation parameters present in the Operation Parameter field. The Operation Parameter Presence Bitmap subfield contains a bitmap indicating whether the i-th field, starting from the Maximum PPDU Length Subfield, exists in the Operation Parameter field; wherein if the i-th entry (i.e., the i-th bit) of the Operation Parameter Presence Bitmap is set to 1, then the i-th field, starting from the Maximum PPDU Length Subfield, exists in the Operation Parameter field; otherwise, it is set to 0.

[0257] In some embodiments, the allowed operation parameter bitmap field is used to indicate the operation parameters that are allowed to be adjusted. The allowed operation parameter bitmap subfield contains a bitmap indicating whether the corresponding operation parameter in the operation parameter field is allowed to be adjusted. Specifically, the allowed operation parameter bitmap subfield indicates whether the operation parameter corresponding to the i-th field starting from the maximum PPDU reception duration subfield in the operation parameter field is allowed to be adjusted, or indicates whether the corresponding operation parameter is negotiable (or updatable). Wherein, if the i-th entry (i.e., the i-th bit) of the allowed operation parameter bitmap is set to 1, it indicates that in the scenario where the first operation mode is enabled, the operation parameter corresponding to the i-th field starting from the maximum PPDU reception duration subfield in the operation parameter field is allowed to be adjusted, or indicates that the corresponding operation parameter is negotiable (or updatable); otherwise, it is set to 0. For example, this field can be used by the second device to notify the first device which operation parameters can be adjusted or updated in the scenario where the first operation mode is enabled.

[0258] In some embodiments, the duration field is located in the information field of the reconfiguration multi-link element; and / or, the operation parameter presence bitmap field is located in the information field of the reconfiguration multi-link element; and / or, the operation parameter field is located in the information field of the reconfiguration multi-link element; and / or, the allowed operation parameter bitmap field is located in the information field of the reconfiguration multi-link element.

[0259] In some embodiments, the first frame, the second frame, or the third frame further includes at least one of the following fields: an operation parameter existence bitmap existence field, which indicates whether the operation parameter existence bitmap field exists; a reconfiguration operation type field, which indicates the multi-link operation update type; an operation parameter existence field, which indicates whether the operation parameter field exists; and an allowed operation parameter bitmap existence field, which indicates whether the allowed operation parameter bitmap field exists.

[0260] In some embodiments, the operation parameter presence field is used to indicate whether the operation parameter field exists. If the operation parameter subfield exists in the first frame, the operation parameter presence subfield is set to 1; otherwise, it is set to 0.

[0261] In some embodiments, the Operation Parameter Existence Bitmap Existence field is used to indicate whether the Operation Parameter Existence Bitmap field exists. If an Operation Parameter Existence Bitmap subfield exists in the first frame, the Operation Parameter Existence Bitmap Existence subfield is set to 1; otherwise, it is set to 0. Optionally, if the Operation Parameter Existence subfield is set to 1 and the Operation Parameter Existence Bitmap Existence subfield is set to 0, the Operation Parameter field contains all the operation parameters it defines.

[0262] In some embodiments, the Allowed Operation Parameter Bitmap Existence field is used to indicate whether the Allowed Operation Parameter Bitmap field exists. If the Allowed Restricted Operation Parameter Bitmap Subfield exists in the first frame, the Allowed Restricted Operation Parameter Bitmap Existence Subfield is set to 1; otherwise, it is set to 0.

[0263] In some embodiments, the reconfiguration operation type field is used to indicate the multi-link operation update type. For example, the multi-link operation update type includes at least one of the following: enabling the first operation mode; disabling the first operation mode; allowing the first operation mode to be enabled; and disallowing the first operation mode to be enabled.

[0264] In some embodiments, different multi-link operation update types are represented by different index values; or, some multi-link operation update types may be represented by the same index value or by different index values. For example, the above four multi-link operation update types are represented by different index values, such as enabling the first operation mode corresponding to index value 5; disabling the first operation mode corresponding to index value 6; allowing the first operation mode to be enabled corresponding to index value 7; and disallowing the first operation mode to be enabled corresponding to index value 8. As another example, the above enabling the first operation mode and allowing the first operation mode may be represented by the same index value, such as index value 5; the above disabling the first operation mode and disallowing the first operation mode may be represented by the same index value, such as index value 6.

[0265] In some embodiments, the operation parameter presence bitmap presence field is located in the control field of the reconfiguration multilink element; and / or, the reconfiguration operation type field is located in the control field of the reconfiguration multilink element; and / or, the operation parameter presence field is located in the control field of the reconfiguration multilink element; and / or, the allowed operation parameter presence bitmap is located in the control field of the reconfiguration multilink element.

[0266] In some embodiments, at least one frame includes a reconfiguration multilink element, which is used to indicate that one or more sites attached to the first device (and / or one or more sites attached to the second device) need to adjust their operating parameters.

[0267] In some embodiments, the reconfiguration of a multi-link element can be used to initiate an operation parameter adjustment operation (or operation parameter update operation) for one or more link-corresponding sites, including changing the operation mode and / or operation parameters of the non-AP MLD's established link-corresponding site. Furthermore, it can be used by the AP MLD to disable the operation mode and / or operation parameters of the non-AP MLD's established link-corresponding site to its associated non-AP MLD. Additionally, it can be used by the AP MLD to notify its associated non-AP MLD whether its associated non-AP MLD's subordinate site is allowed to enter the operation mode, and / or, if allowed, to notify the permitted operation parameters. Optionally, the reconfiguration of a multi-link element can be used by the AP MLD (i.e., the Mobile AP MLD) to change the operation mode and / or operation parameters of its subordinate AP.

[0268] In some embodiments, the first frame or the second frame includes a conversion timeout subfield, which indicates the conversion timeout period for the exchange of frames between the first frame and the second frame.

[0269] In some embodiments, the transition timeout subfield is used to indicate the transition timeout period for the exchange of the first frame and the second frame. For example, both the first frame and the second frame are multi-link operation parameter update notification frames. The transition timeout field indicates the transition timeout period for the exchange of multi-link operation parameter update notification frames for the first operation mode. For instance, in a notification-based first operation mode enable / disable operation, after a non-AP MLD successfully sends a multi-link operation parameter update notification frame to its associated AP MLD to notify the enabling of the restricted operation mode of its corresponding site, if no multi-link operation parameter update notification frame is received from the AP MLD within the transition timeout period indicated by the transition timeout field, the first operation mode of its corresponding site is enabled when the timeout period arrives (or expires). Specifically, when the frame sent by the AP of the AP MLD includes the transition timeout subfield, the setting of the transition timeout subfield is as defined in Table 2. The frame sent by the non-AP STA of the non-AP MLD does not include the transition timeout field. In particular, the APs attached to the AP MLD can also publish the transition timeout information for the multi-link operation parameter update notification frame exchange for the first operating mode by carrying the transition timeout subfield in other management frames they send (such as beacon frames, probe response frames).

[0270] Table 2 Conversion Timeout Subfield Encoding (Example)

[0271] TU is a unit of time measurement equal to 1024 μs (microseconds). Tus represents multiple TUs.

[0272] In some embodiments, the fourth frame includes at least one of the following fields: a quantity field, which indicates the number of reconfiguration status groups in the reconfiguration status list field; and a reconfiguration list field, which includes at least one reconfiguration status group field, which indicates whether the second device accepts the request corresponding to the reconfiguration status group field.

[0273] In some embodiments, the quantity subfield is set to the number of reconfiguration state groups in the reconfiguration state list subfield.

[0274] In some embodiments, the reconfiguration state list subfield contains one or more reconfiguration state tuples.

[0275] In some embodiments, the fourth frame further includes at least one of the following fields: a Category field; a Protected UHR Action field; and a conversation token field, which is used to verify the conversation between the second device and the first device.

[0276] In some embodiments, session tokens are typically used to manage frame exchange, particularly in scenarios requiring multiple round trips, such as connection establishment and key negotiation. The primary function of a session token is to ensure that frame exchange is sequential and orderly, thereby avoiding confusion and errors. Here, it is used to verify frame exchange between a multilink operation parameter update request frame and a multilink operation parameter update response frame. For example, when the second device sends a multilink operation parameter update response frame (i.e., the fourth frame), this field is set to the value of the session token field from the corresponding multilink operation parameter update request frame (i.e., the first frame).

[0277] In some embodiments, the reconfiguration status group field includes at least one of the following subfields: a link identifier subfield, used to identify a link; a status subfield, used to indicate whether the second device accepts the request corresponding to the link; and an allowed restricted operation parameter bitmap subfield, used to indicate the reason for rejecting the request.

[0278] In some embodiments, the Link Identifier subfield represents the link identifier of the link where the site requesting the first mode operation resides. The Link Identifier subfield is a field within the Link Identification Information (Link ID Info) subfield. The Link Identification Information subfield includes the Link Identifier subfield corresponding to at least one link. That is, the reconfiguration status group field includes the Link Identification Information subfield.

[0279] In some embodiments, the Status subfield indicates the operational status of the first operation mode of the link corresponding to the Link Identifier subfield. For example, a value of 0 in the Status subfield indicates that the first operation mode of the corresponding link has been successfully operated, i.e., the multi-link operation parameter update request for the corresponding link has been accepted; a value of a non-zero value in the Status subfield (e.g., indicating 141 (DENIED_OPERATION_PARAMETER_UPDATE)) indicates that the multi-link operation parameter update request for the corresponding link has been rejected.

[0280] In some embodiments, when the value of the status subfield is zero (i.e., indicating acceptance of the multi-link operation parameter update request for the corresponding link), the reconfiguration status tuple subfield does not contain the allowed operation parameter bitmap subfield.

[0281] In some embodiments, when the value of the status subfield is non-zero (i.e., indicating a rejection of the multi-link operation parameter update request for the corresponding link), the reconfiguration status tuple subfield contains an allowed operation parameter bitmap subfield. The allowed operation parameter bitmap subfield is used to further indicate the reason for rejection, such as because updating or adjusting one or more operation parameters in the requested operation parameter field is not permitted.

[0282] The allowed operation parameter bitmap subfields can be found in the description of the allowed operation parameter bitmap subfields included in the first, second, or third frame above, and will not be repeated here.

[0283] In some embodiments, the first frame is any one of the following frames: a multi-link operation parameter update notification frame; a multi-link operation parameter update request frame; or a multi-link operation parameter update disabling frame. In some embodiments, the second and / or third frame is a multi-link operation parameter update notification frame. In some embodiments, the fourth frame is a multi-link operation parameter update response frame.

[0284] Next, taking the first operation mode as a restricted operation mode as an example, we will list the frame formats corresponding to the first frame, the second frame, the third frame, and the fourth frame one by one.

[0285] • Restricted operation parameter field.

[0286] For example, as shown in Figure 8, the restricted operation parameter field includes at least one of the following subfields: maximum receive PPDU duration; maximum transmit PPDU duration; maximum receive MCS; maximum transmit MCS; LDPC mode; HT instantaneous BA mode; disabled subchannel bitmap; maximum A-MPDU length exponent; maximum A-MPDU length exponent extension; minimum MPDU start interval; MPDU multi-user spacing factor; TID aggregation transmission limit; TID aggregation reception limit; segmented A-MSDU fragmentation mode; maximum transmit power; minimum target receive power; recommended AC. Explanations of these subfields can be found in "5. Frame Structure During Parameter Adjustment" above, and will not be repeated here.

[0287] • Reconfigure multi-link elements.

[0288] First, the format of a reconfigurable multilink element is shown. One reconfigurable multilink element corresponds to one multilink device (i.e., AP MLD or non-AP MLD).

[0289] In some embodiments, the reconfiguration of a multi-link element includes at least one per-STA profile subelement, each of the at least one per-STA profile subelement being used to indicate configuration information corresponding to one of the at least one links in the multi-link device, or in other words, each of the at least one per-STA profile subelement being used to indicate configuration information corresponding to a STA or AP operating on one of the at least one links in the multi-link device.

[0290] In some embodiments, each site configuration sub-element includes control fields and / or information fields.

[0291] In some embodiments, the control field, as shown in Figure 9, includes at least one of the following fields: a restricted operation parameter existence bitmap existence field; a reconfiguration operation type field; a restricted operation parameter existence field; and a allowed restricted operation parameter bitmap existence field. It should be noted that the restricted operation parameter existence bitmap existence field, the restricted operation parameter existence field, and the allowed restricted operation parameter bitmap existence field can be modified accordingly for different first operation modes. The restricted operation parameter existence bitmap existence field can be referenced from the "Operation Parameter Existence Bitmap Existence Field" shown above, and the allowed restricted operation parameter bitmap existence field can be referenced from the "Allowed Operation Parameter Bitmap Existence Field" shown above; further details are omitted here.

[0292] In some embodiments, the control field further includes at least one of the following fields: link identifier field; complete configuration file field; STA MAC address present field; AP removal timer present field; operation parameter present field; NSTR indicator bitmap present field; NSTR indicator bitmap present field.

[0293] The reconfiguration operation type field indicates the multi-link operation update type through an index value. For example, enabling the first operation mode and allowing the first operation mode to be enabled use the same index value, while disabling the first operation mode and disallowing the first operation mode use the same index value. This index value can be set as shown in Table 3.

[0294] Table 3. Subfield Encoding of Reconfiguration Operation Type

[0295] For example, when the value of the reconfiguration operation type subfield is 5 (or set to other reserved values), the multi-link operation update type of the link indicated by the link identifier field is enabled as Limited Operation Enabled, that is, the site corresponding to the link indicated by the link identifier field is enabled as a limited operation mode or the limited operation parameters are updated.

[0296] For example, when the value of the reconfiguration operation type subfield is 6 (or set to other reserved values), it indicates that the multi-link operation update type of the link indicated by the link identifier field is Limited Operation Disabled, that is, the limited operation mode of the site corresponding to the link indicated by the disabled link identifier field, that is, the limited operation parameter update that the disabled site has performed.

[0297] In some embodiments, the information fields are as shown in Figure 10. The information fields include at least one of the following: a duration field; a restricted operation parameter existence bitmap field; a restricted operation parameter field; and a allowed restricted operation parameter bitmap field. It should be noted that the restricted operation parameter existence bitmap field, the restricted operation parameter field, and the allowed restricted operation parameter bitmap field can be modified accordingly for different first operation modes. The restricted operation parameter existence bitmap field can be referenced to the "Operation Parameter Existence Bitmap Field" shown above, the restricted operation parameter field can be referenced to the "Operation Parameter Field" shown above, and the allowed restricted operation parameter bitmap field can be referenced to the "Allowed Operation Parameter Bitmap Field" shown above; further details will not be repeated here.

[0298] In some embodiments, the information field further includes at least one of the following fields: STA information length field; STA MAC address field; AP removal timer field; operation parameter field.

[0299] • Multi-link operation parameter update notification frame.

[0300] In some embodiments, the multi-link operation parameter update notification frame can be the first frame in "Interaction Method 1: Notification" of "3. Interaction during parameter adjustment" above; and / or, the multi-link operation parameter update notification frame can be the second frame in "Interaction Method 1: Notification" of "3. Interaction during parameter adjustment" above; and / or, the multi-link operation parameter update notification frame can be the third frame in "Interaction Method 1: Notification" of "3. Interaction during parameter adjustment".

[0301] Multi-link operation parameter update notification frames can be used by an AP MLD to disable the restricted operation mode of a site with an established link to its associated non-AP MLD, and by an AP MLD to notify its associated non-AP MLD whether the restricted operation mode is allowed (or enabled), and if allowed, which operation parameters can be adjusted. Alternatively, a multi-link operation parameter update notification frame can be used by a non-AP MLD to notify its associated AP MLD of changes to the restricted operation mode and / or restricted operation parameters of the site. Optionally, a multi-link operation parameter update notification frame can also be used by an AP MLD (e.g., a Mobile AP MLD) to change the restricted operation mode and / or restricted operation parameters of its associated AP.

[0302] Multi-link operation parameter update notification frames can be protected UHR class action frames. The action field of the multi-link operation parameter update notification frame contains information as shown in Table 4 (Format of Action Field of Protected Multi-link Operation Parameter Update Notification Frame).

[0303] Table 4. Format of Action Field in Protected Multilink Operation Parameter Update Notification Frame

[0304] The Category field is defined in IEEE standard 9.4.1.11 (Action field).

[0305] The Protected UHR Action field is defined in the IEEE standard (Protected UHR Action field).

[0306] The conversation token field is a non-zero value selected by the sending AP MLD to identify a notification / request / response sequence.

[0307] The multi-link operation parameter update notification frame contains 0 or 1 reconfiguration multi-link elements, wherein the definition of the reconfiguration multi-link elements is as described above.

[0308] The Transition Timeout field indicates the timeout period for exchanging multi-link operation parameter update notification frames for restricted operation modes. For example, in notification-based restricted operation mode enabling / disabling operations, after a non-AP MLD successfully sends a multi-link operation parameter update notification frame to its associated AP MLD to notify it of enabling restricted operation mode for its corresponding site, if it does not receive a response multi-link operation parameter update notification frame from the AP MLD within the timeout period indicated by the Transition Timeout field, then the restricted operation mode for its corresponding site will be enabled when the timeout period expires. Specifically, when a frame sent by an AP attached to an AP MLD includes a Transition Timeout subfield, the settings for the Transition Timeout subfield are defined in the table (Code for Transition Timeout Subfield). Frames sent by a non-AP STA attached to a non-AP MLD do not include a Transition Timeout field. In particular, APs attached to the AP MLD can also publish timeout information for the exchange of multi-link operation parameter update notification frames for restricted operating modes by carrying a transition timeout subfield in other management frames they send (such as beacon frames and probe response frames).

[0309] • Multi-link operation parameter update disabled frames.

[0310] In some embodiments, the multi-link operation parameter update disabled frame can be the first frame in "Interaction Method 1: Notification" in "3. Interaction during parameter adjustment" above.

[0311] The Multi-Link Operation Parameter Update Disable Frame is used by an MLD to request or notify its peer MLD to disable negotiated (or enabled) restricted operation parameter updates. Specifically, a non-AP MLD affiliate site (or restricted operation mode requester) in restricted operation mode can send a Multi-Link Operation Parameter Update Disable Frame to its associated AP MLD affiliate AP (or restricted operation mode responder) to request or notify the AP MLD to exit restricted operation mode (i.e., disable previously negotiated or enabled restricted operation parameter updates); alternatively, an AP MLD affiliate AP (or restricted operation mode responder) can also send a Multi-Link Operation Parameter Update Disable Frame to a non-AP MLD affiliate site (or restricted operation mode requester) in restricted operation mode to request or notify the non-AP MLD to exit restricted operation mode (i.e., disable previously negotiated or enabled restricted operation parameter updates).

[0312] Multilink operation parameter update disabled frames can adopt the protected action frame (or notification frame) format defined by the IEEE 802.11 standard. The information contained in the action field of the multilink operation parameter update disabled frame is shown in Table 5.

[0313] Table 5. Format of Action Field in Protected Multilink Operation Parameter Update Non-Enabled Frames

[0314] The category field is defined according to the relevant definition in the IEEE 802.11 standard.

[0315] The protected UHR action field contains 1 byte, which follows the category field and is used to distinguish the UHR action frame format.

[0316] • Multi-link operation parameter update request frame.

[0317] In some embodiments, the multi-link operation parameter update request frame can be the first frame in "Interaction Method Two: Negotiation" in "3. Interaction in the Parameter Adjustment Process" above.

[0318] Multi-link operation parameter update request frames can be used by non-AP MLDs to request changes to the restricted operation mode and / or restricted operation parameters of the site corresponding to the non-AP MLD.

[0319] Multilink operation parameter update request frames can be protected UHR class action frames, and can be updated based on the protected action frame format defined by the IEEE 802.11 specification. The action field of the multilink operation parameter update request frame contains information as shown in the table (Protected Multilink Operation Parameter Update Request Frame Action Field Format).

[0320] Table 6. Format of Action Field in Protected Multilink Operation Parameter Update Request Frame

[0321] The Category field is defined in IEEE standard 9.4.1.11 (Action field).

[0322] The Protected UHR Action field is defined in the IEEE standard (Protected UHR Action field).

[0323] The dialogue token field is a non-zero value selected by the non-AP MLD that sent the frame, used to identify the request / response sequence.

[0324] The multi-link operation parameter update notification frame contains one reconfiguration multi-link element, wherein the definition of the reconfiguration multi-link element is as described above.

[0325] • Multi-link operation parameter update response frame.

[0326] In some embodiments, the multi-link operation parameter update request frame can be the fourth frame in "Interaction Method 2: Negotiation" in "3. Interaction in the parameter adjustment process" above.

[0327] Multi-link operation parameter update response frames can be used by the AP MLD to respond to restricted operation mode requests sent by its associated non-AP MLD.

[0328] The multi-link operation parameter update response frame can be a protected UHR class action frame, and can be updated based on the protected action frame format defined by the IEEE 802.11 specification. The action field of the multi-link operation parameter update response frame contains information as shown in the table (Protected Multi-Link Operation Parameter Update Response Frame Action Field Format).

[0329] Table 7 Format of Action Field in Protected Multilink Operation Parameter Update Response Frame

[0330] The Category field is defined in IEEE standard 9.4.1.11 (Action field). The Protected UHR Action field is defined in the IEEE standard (Protected UHR Action field). The Dialogue Token field is set to the value of the Dialogue Token field from the corresponding Multilink Operation Parameter Update Request frame. The Quantity subfield is set to the number of reconfiguration state groups in the Reconfiguration State List subfield.

[0331] The reconfiguration status list subfield contains one or more reconfiguration status tuples, as shown in Figure 11.

[0332] The Link ID subfield in the Link ID Info subfield represents the link identifier of the link containing the site requesting restricted mode operation. The Status subfield indicates the restricted operation mode status of the link corresponding to the Link ID subfield. For example, a Status subfield value of 0 indicates that the restricted operation mode operation of the corresponding link was successful, i.e., the multi-link operation parameter update request for the corresponding link was accepted; a Status subfield value of non-zero (e.g., 141 (DENIED_OPERATION_PARAMETER_UPDATE)) indicates that the multi-link operation parameter update request for the corresponding link was rejected. When the Status subfield value is zero (i.e., indicating that the multi-link operation parameter update request for the corresponding link was accepted), the Reconfiguration Status tuple subfield does not contain the allowed restricted operation parameter bitmap subfield. When the Status subfield value is non-zero (i.e., indicating that the multi-link operation parameter update request for the corresponding link was rejected), the Reconfiguration Status tuple subfield contains the allowed restricted operation parameter bitmap subfield. The Allowed Restricted Operation Parameters bitmap subfield is used to further indicate the reason for rejection, such as because one or more restricted operation parameters in the requested restricted operation parameters field are not allowed to be updated or adjusted.

[0333] The allowed restricted operation parameter bitmap subfield contains a bitmap indicating whether the corresponding restricted operation parameter in the restricted operation parameter field is allowed to be adjusted. Specifically, it indicates whether the parameter corresponding to the i-th field starting from the maximum PPDU reception duration subfield is allowed to be adjusted, or indicates whether the corresponding parameter is negotiable (or updatable). If the i-th entry of the bitmap is set to 1, it indicates that in the restricted operation mode, the parameter corresponding to the i-th field starting from the maximum PPDU reception duration subfield in the restricted operation parameter field is allowed to be adjusted, or indicates that the corresponding parameter is negotiable (or updatable); otherwise, it is set to 0.

[0334] It should be noted that the field formats, element formats, byte counts, frame formats, etc. shown in the embodiments of this application are all optional examples. This application supports any adaptive modifications to the frame formats, field formats, and element formats of related frames based on the frame formats, field formats, and element formats shown in the embodiments of this application (as shown in any of Figures 8 to 14), such as adding fields, removing some fields, recombining some fields, changing the byte count, changing the field name, etc.

[0335] To reiterate, the frame formats, element formats, and field formats shown in the above embodiments are merely examples and not limitations. This application supports modifications to the formats of each frame, element, and field based on the format designs described above. For example, it supports changing the order of fields / elements, the number of bytes in fields / elements, the number of bits in fields / elements, the name of fields / elements / frames, etc. It also supports setting some fields / elements as reserved fields, and others as obsolete fields. Furthermore, it supports setting check bits, presence bits, etc., for some fields / elements.

[0336] It should be understood that the format, name, and value of the frames / elements / fields involved in the various embodiments of this application are merely examples and do not imply any limitation on the format, name, and value of the frames / elements / fields. In different embodiments or designs, it is possible that one or more of the aforementioned element / field names, their positions in the frame, their arrangement order with other elements / fields, the number of bytes occupied, or the number of bits occupied may change. Similarly, in different embodiments or designs, it is possible that one or more of the aforementioned frame names, included elements / fields, the number of bytes occupied, or the number of bits occupied may change.

[0337] For sites operating in coexistence or subject to environmental interference, the restricted operation reporting and coexistence mechanism allows the site (e.g., STA1) to notify its peer STA (e.g., STA2) of adjustments to Wi-Fi communication transmission and reception parameters and related restricted operations. In particular, the restricted operation reporting and coexistence mechanism is a parameter update mechanism based on management-level signaling, which allows STA1 to limit its operational capabilities when encountering coexistence problems within the device.

[0338] The restricted operating parameters (or adjusted operating parameters) reported by the site may include, but are not limited to: maximum PPDU duration for reception or transmission, maximum MCS for transmission or reception, LDPC mode, Block Acknowledgment (BA) mode parameters, and disabled subchannel bitmaps. Specifically, the adjustment or update of these restricted operating parameters may be due to the site needing to share communication resources based on the time domain and / or frequency domain, as well as sharing computational or processing resources of memory, RF modules, and processing modules between Wi-Fi and other wireless technologies (such as Bluetooth); or, the adjustment or update of these restricted operating parameters may also be due to interference affecting the site.

[0339] Once a station (e.g., STA1) successfully reports its restricted operating parameters and / or receives an acceptance (ACCEPT) instruction (if required) from its peer station (e.g., STA2), it applies the updated restricted operating parameters. If the peer station (e.g., STA2) successfully receives and / or accepts (if required) the updated restricted operating parameters reported by STA1, it schedules and processes data based on the updated restricted operating parameters reported by STA1 and coordinates communication with STA1. Therefore, through restricted operating parameter reporting and coexistence mechanisms, packet loss or decreased communication efficiency caused by the inability to synchronize restricted operating parameter updates in a timely manner can be avoided or reduced.

[0340] If STA1 is a non-AP STA, then its peer site (i.e., STA2) is the AP associated with the non-AP STA; if STA1 is an AP, then its peer site (i.e., STA2) is a non-AP STA associated with that AP.

[0341] This application proposes a signaling and processing mechanism based on the adjustment of restricted operation parameters for restricted operation modes. This includes an operation method and signaling mechanism for a station (STA1) in a coexistence or interference environment to enter or exit restricted operation mode (i.e., real-time adjustment mode of operation parameters). Specifically, it includes:

[0342] 1. Provide an interactive protocol and signaling mechanism for sites in coexisting or interfering environments to enter restricted operation mode by notifying the AP or negotiating with the AP, including a mechanism for exiting restricted operation mode and reconfiguring the updated definition of multi-link elements.

[0343] 2. Methods and mechanisms for restricting STA1 from entering restricted operation mode, including one or more of the following: 1) Enabling or disabling the function of the peer site of STA1 (such as the AP associated with STA1) to provide services to the site (i.e., STA1) entering restricted operation mode; 2) Limiting the range of operating parameters that the site entering restricted operation mode can adjust in real time, and the AP can notify or publish the range of operating parameters that it can support for the site in restricted operation mode to adjust in real time; 3) STA1 needs to negotiate with its peer site (such as the AP associated with STA1) before entering restricted operation mode, and the AP can accept or reject the request of STA1 to enter restricted operation mode.

[0344] The method provided in this application has two advantages: first, it coordinates the operation rules of a site entering restricted operation mode with the peer site serving that site, avoiding conflicts and unnecessary signaling interactions caused by parameter adjustments; second, it avoids or reduces the complexity of scheduling and responding for APs serving sites in restricted operation mode.

[0345] • Enable / disable operation based on notification-based restricted operation mode

[0346] ① AP-initiated permission / disallowment of restricted operation mode operation

[0347] The AP MLD can send a separately addressed multi-link operation parameter update notification frame to the non-AP MLD to indicate whether restricted operation mode is allowed (or enabled), and if allowed, which operation parameters can be adjusted, or to disable restricted operation mode for the site corresponding to the link already established by the non-AP MLD. Specifically, the AP MLD can also indicate whether restricted operation mode is allowed (or enabled), and if allowed, which operation parameters can be adjusted, in other management frames (such as beacon frames and probe response frames).

[0348] • Disabled operation / Operation not allowed

[0349] AP MLDs can disable the restricted operating mode of sites with established links on their associated non-AP MLDs by sending a separately addressed multi-link operation parameter update notification frame to the non-AP MLDs. The multi-link operation parameter update notification frame should contain zero or one reconfiguration multi-link element. When the multi-link operation parameter update notification frame contains one reconfiguration multi-link element, this element contains a per-STA profile subelement for each affiliated AP associated with the site for which the AP MLD disables the restricted operating mode on the non-AP MLD.

[0350] In the link reconfiguration notification frame, the AP MLD should set the MLD MAC address presence subfield, EML capability presence subfield, MLD capability and operation presence subfield, and extended MLD capability and operation presence subfield in the common information field of the reconfigured multi-link element to 0. Meanwhile, the following rule applies to the per-site configuration sub-element in the reconfigured multi-link element included in the multi-link operation parameter update notification frame:

[0351] - If the AP MLD is disabled and the non-AP MLD has established a restricted operating mode for the site corresponding to the link, it should set the following field in the per-site configuration sub-element:

[0352] • The Link ID subfield should be set to the link identifier of the AP associated with the site of the non-AP MLD that is currently in non-enabled restricted operation mode.

[0353] • The following subfields should be set to 0: complete configuration file subfield, STA MAC address subfield, AP remove timer subfield, operation parameter subfield, and NSTR indicator bitmap subfield.

[0354] • Setting the value of the reconfiguration operation type subfield to 6 indicates that the multi-link operation (MLO) update type of the link indicated by the link ID subfield is limited operation disabled. In other words, it disables the limited operation mode of the site corresponding to the link indicated by the link ID subfield, which means that the limited operation parameter update has been performed on the disabled site.

[0355] • Enable / Allow operation

[0356] The AP MLD can notify its associated non-AP MLD whether restricted operation mode is allowed (or enabled) and, if so, which operation parameters can be adjusted by sending a separately addressed multi-link operation parameter update notification frame to the non-AP MLD. The multi-link operation parameter update notification frame should contain a reconfiguration multi-link element. This element contains a per-STA profile subelement for each affiliated AP associated with the corresponding site for which restricted operation mode is enabled by the AP MLD.

[0357] In the link reconfiguration notification frame, the AP MLD should set the MLD MAC address presence subfield, EML capability presence subfield, MLD capability and operation presence subfield, and extended MLD capability and operation presence subfield in the common information field of the reconfigured multi-link element to 0. The following rules apply to the per-site configuration sub-element in the reconfigured multi-link element contained in the multi-link operation parameter update notification frame:

[0358] If the AP MLD allows the corresponding site on the link to enter restricted operation mode, it should set the following field in the per-site configuration sub-element:

[0359] • The Link ID subfield should be set to the link identifier of the AP associated with the site corresponding to the non-AP MLD that enables restricted operation mode.

[0360] • The following subfields should be set to 0: complete configuration file subfield, STA MAC address subfield, AP remove timer subfield, operation parameter subfield, and NSTR indicator bitmap subfield.

[0361] • Setting the value of the reconfiguration operation type subfield to 5 indicates that the multi-link operation (MLO) update type of the link indicated by the link ID subfield is limited operation enabled, which means that limited operation parameter updates are allowed for the site corresponding to the link indicated by the link ID subfield.

[0362] The allowed restricted operation parameter bitmap indicates the restricted operation parameters that are allowed to be updated or adjusted. When the value of a bit at a certain position in the allowed restricted operation parameter bitmap is 1, the restricted operation parameter corresponding to that bit is allowed to be updated; otherwise, the update is not allowed.

[0363] ② Enable / disable restricted operation mode initiated by non-AP STA

[0364] The non-AP MLD can determine, based on indications (if any) in the multi-link operation parameter update notification frame or other management frames (such as beacon frames, probe response frames) sent by the AP MLD, which APs attached to the AP MLD are allowed (or enabled) restricted operation modes, and if allowed, which restricted operation parameters can be adjusted. Therefore, based on the AP MLD's indication, the non-AP MLD can determine whether to initiate a restricted operation mode enabling operation; simultaneously, it determines that if a restricted operation mode enabling operation is initiated, the relevant restricted operation parameters for enabling the restricted operation mode will be set according to the allowed restricted operation parameter indications (if any).

[0365] When a non-AP MLD that supports restricted operation mode is ready to enable (or disable) its restricted operation mode, the non-AP MLD can send a multi-link operation parameter update notification frame to the peer site (such as the AP associated with that site), as shown in Figure 12.

[0366] • Enable restricted operation mode

[0367] For example, when a non-AP MLD enables restricted operation mode, the multi-link operation parameter update notification frame sent by the station carries a reconfiguration multi-link element. This element contains a per-STA profile subelement for each affiliated STA associated with the corresponding station that the non-AP MLD indicates to the AP MLD to enable restricted operation mode.

[0368] In the link reconfiguration notification frame, the non-AP MLD should set the MLD MAC address presence subfield, EML capability presence subfield, MLD capability and operation presence subfield, and extended MLD capability and operation presence subfield in the common information field of the reconfigured multi-link element to 0. Meanwhile, the following rule applies to the per-site configuration sub-element in the reconfigured multi-link element included in the multi-link operation parameter update notification frame:

[0369] Set the following fields in the configuration sub-element for each site:

[0370] • The Link ID subfield should be set to the link identifier of the non-AP MLD site that is currently in restricted operation mode.

[0371] • The following subfields should be set to 0: complete configuration file subfield, STA MAC address subfield, AP remove timer subfield, operation parameter subfield, and NSTR indicator bitmap subfield.

[0372] • Setting the value of the reconfiguration operation type subfield to 5 indicates that the multi-link operation (MLO) update type of the link indicated by the link ID subfield is limited operation enabled. This enables the limited operation mode of the site corresponding to the link indicated by the link ID subfield, which means enabling the limited operation parameter update of the site.

[0373] • Optional: Include a duration subfield, which indicates the duration for which the site corresponding to the link indicated by the link ID subfield is in restricted operation mode. Specifically, if a duration subfield exists, the site corresponding to the link indicated by the link ID subfield, if it successfully enters restricted operation mode, will exit restricted operation mode after the time indicated by the duration subfield.

[0374] When the peer site device (such as AP MLD) receives a multi-link operation parameter update notification frame and is ready to provide services to the site that will be in restricted operation mode, in response to the received multi-link operation parameter update notification frame, the peer site sends a multi-link operation parameter update notification frame to the site within the transition timeout interval, and the following rules apply:

[0375] a) The transition timeout subfield carried in the management frame (e.g., association response frame, or multi-link operation parameter update notification frame) sent by the corresponding peer site (e.g., AP) indicates the transition timeout period. When the frame sent by the peer site (e.g., AP) contains a transition timeout subfield, the setting of the transition timeout subfield can be defined using the transition timeout subfield encoding (example) defined in the table. Here, TU is a time unit equal to 1024 μs (microseconds).

[0376] b) The transition timeout begins at the end of the PPDU[+SigExt] (i.e., the PPDU plus a signal extension immediately following the PPDU (if the signal extension exists) or the PPDU (if the signal extension does not exist)), which is sent by the peer station and carries an immediate acknowledgment (ACK) of the multi-link operation parameter update notification frame sent to that station.

[0377] The site will enter restricted operation mode when one of the following situations occurs (whichever occurs first):

[0378] a) At the end of the conversion timeout period, or

[0379] b) Before the transition timeout expires, and immediately after sending an acknowledgment (ACK) as a response to a received multi-link operation parameter update notification frame from the peer site (e.g., AP).

[0380] • Non-enabled restricted operation mode

[0381] (1) By sending multi-link operation parameter update notification frames

[0382] When a site supporting restricted operation mode is about to disable or deactivate its restricted operation mode, it transmits a multilink operation parameter update notification frame to the peer site (such as the AP associated with that site). The reconfiguration multilink element carried in this frame indicates that the non-AP MLD is deactivating the restricted operation mode of the corresponding site. It should have the following fields set in each site's configuration sub-element:

[0383] • The Link ID subfield should be set to the link identifier of the link where the non-AP MLD corresponding site is located, which is currently in non-enabled restricted operation mode.

[0384] • The following subfields should be set to 0: complete configuration file subfield, STA MAC address subfield, AP remove timer subfield, operation parameter subfield, and NSTR indicator bitmap subfield.

[0385] • Setting the value of the reconfiguration operation type subfield to 6 indicates that the multi-link operation (MLO) update type of the link indicated by the link ID subfield is limited operation disabled. In other words, it disables the limited operation mode of the site corresponding to the link indicated by the link ID subfield, which means that the limited operation parameter update has been performed on the disabled site.

[0386] When a peer site (such as an AP) stops providing services to a site that will be in restricted operation mode, in response to the received restricted operation mode notification frame, the peer site sends a multi-link operation parameter update notification frame to that site within the transition timeout interval.

[0387] The site will exit or disable restricted operation mode if one of the following occurs (whichever occurs first):

[0388] a) At the end of the conversion timeout period, or

[0389] b) Before the transition timeout expires, and immediately after sending an acknowledgment (ACK) as a response to a received restricted operation mode notification frame from the peer site (e.g., AP).

[0390] (2) Autonomous exit based on the duration information indicated by the enabled restricted operation mode

[0391] When the non-AP MLD enables restricted operation mode, if the reconfiguration multi-link element carried in the multi-link operation parameter update notification frame sent by the non-AP MLD subsidiary site contains a duration sub-field in the per-STA profile subelement associated with each subsidiary STA that enables restricted operation mode for the non-AP MLD, then the site corresponding to the link indicated by the link ID sub-field in the per-STA profile subelement will automatically exit the restricted operation mode after the duration sub-field has elapsed if it successfully enters the restricted operation mode.

[0392] (3) Updating disabled frames by sending multi-link operation parameters

[0393] A non-AP MLD affiliated site (or restricted operation mode requester) that is already in restricted operation mode can send a multi-link operation parameter update disallowed frame to its associated AP MLD affiliated AP (or restricted operation mode responder) to request or notify the AP MLD to exit restricted operation mode (i.e., the restricted operation parameter update negotiated or enabled before disallowing).

[0394] Alternatively, the AP MLD-affiliated AP (or restricted operation mode responder) may also send a multi-link operation parameter update disallow frame to the non-AP MLD-affiliated site (or restricted operation mode requester) in restricted operation mode to request or notify the non-AP MLD to exit restricted operation mode (i.e., the restricted operation parameter update negotiated or enabled before disallowing).

[0395] ③ Enable / disable restricted operation mode operation initiated by AP MLD (such as Mobile AP MLD)

[0396] AP MLDs (such as Mobile AP MLDs) can also change the restricted operating mode and / or restricted operating parameters of their associated APs by sending multi-link operation parameter update notification frames.

[0397] For example, when a Mobile AP MLD supporting restricted operation mode is about to enable (or disable) its restricted operation mode, the Mobile AP MLD can send a multi-link operation parameter update notification frame to the peer site (such as a non-AP MLD associated with this AP MLD), as shown in Figure 13. For specific signaling methods, please refer to the corresponding mechanism in "② Enable / Disable Restricted Operation Mode Operation Initiated by a Non-AP STA".

[0398] • Enable / disable operation based on negotiation-based restricted operation mode

[0399] When a non-AP MLD that supports restricted operation mode is ready to enable (or disable) its restricted operation mode or adjust the operation parameters of its restricted operation mode, the non-AP MLD can send a multi-link operation parameter update request frame to the peer site (such as the AP associated with that site), as shown in Figure 14.

[0400] Specifically, a non-AP MLD can request a multi-link operation update request frame by sending a multi-link operation update request frame. This frame contains a reconfiguration multi-link element, where the reconfiguration operation type subfield is set to 5, which is used to notify the responding AP MLD of changes to its restricted operation mode and / or restricted operation mode parameters.

[0401] In the reconfiguration multilink element where the reconfiguration operation type subfield is set to 5 in the multilink operation update request frame, it is sent by the request non-AP MLD:

[0402] - In the reconfiguration of multi-link elements, all subfields in the presence bitmap subfield of the multi-link control field should be set to 0.

[0403] - The Link ID subfield should be set to the link identifier of the link to which the restricted operation parameters are applied.

[0404] - The "Restricted operation parameters exist" subfield should be set to 1.

[0405] - The Restricted Operation Parameters subfield should indicate the restricted operation parameters of the link identified by the value of the Link ID subfield.

[0406] When the responding AP MLD receives a multilink operation update request frame containing a reconfiguration element with the reconfiguration operation type subfield equal to 5, it should respond with a multilink operation update response frame. If the responding AP MLD accepts a request for a restricted operation mode from a non-AP MLD, the status code subfield of the multilink operation update response frame should be set to success.

[0407] Before receiving a multilink operation update response frame, restricted operations requesting a non-AP MLD must not apply the updated restricted operation parameters indicated in the reconfiguration multilink element of the corresponding multilink operation update request frame. Before successfully sending a multilink operation update response frame, the responding AP MLD must not apply the restricted operation parameters indicated in the reconfiguration multilink element of the corresponding multilink operation update request frame.

[0408] Upon receiving a multilink operation update response frame with a status code of SUCCESS, the non-AP MLD is requested to adopt the updated restricted operation parameters indicated in the multilink operation update request frame. After successfully sending a multilink operation update response frame with a status code of SUCCESS, the non-AP STA attached to the non-AP MLD is requested to adopt the restricted operation parameters indicated in the restricted operation parameter subfield of the reconfigured multilink element in the corresponding multilink operation update request frame.

[0409] In the multi-link operation update response frame, the AP MLD should include one or more reconfiguration status tuple subfields, each subfield corresponding to the link ID indicated in the Per-STA Profile sub-element of the corresponding multi-link operation update request frame. If the AP MLD accepts a restricted mode operation request for the link ID, the corresponding Status subfield in the reconfiguration status subfield should be set to success (i.e., SUCCESS).

[0410] If the AP MLD rejects the restricted mode operation request for the link corresponding to the link ID, the corresponding Status subfield in the reconfiguration status subfield should be set to a non-zero value, such as 141 (DENIED_OPERATION_PARAMETER_UPDATE). Specifically, the corresponding reconfiguration status tuple subfield should also carry an allowed restricted operation parameter bitmap subfield to further indicate the reason for rejection, such as because updating or adjusting one or more restricted operation parameters in the requested restricted operation parameter field is not allowed. The allowed restricted operation parameter bitmap subfield contains a bitmap indicating whether adjustment of the corresponding restricted operation parameter in the restricted operation parameter field is allowed. Specifically, it indicates whether adjustment of the parameter corresponding to the i-th field starting from the maximum PPDU duration subfield is allowed, or whether the corresponding parameter is negotiable (or updatable). If the i-th entry in the bitmap is set to 1, it indicates that, in restricted operation mode, adjustment of the parameter corresponding to the i-th field starting from the maximum PPDU duration subfield in the restricted operation parameter field is allowed, or that the corresponding parameter is negotiable (or updatable); otherwise, it is set to 0. For example, in the restricted mode operation request for the link corresponding to Link1 (identified by LINK ID), the non-AP MLD indicates that the HT-Immediate BA Mode subfield is 0, meaning that when the STA is in restricted operation mode, all HT-Immediate BA protocols are suspended. Upon receiving the restricted mode operation request from the non-AP MLD, the AP MLD, due to its own data processing and scheduling needs, does not allow the HT-Immediate BA protocol to be suspended. Therefore, in the allowed restricted operation parameter bitmap subfield of the reconfiguration status tuple corresponding to Link1, the bit corresponding to the HT-Immediate BA Mode field is set to 0, indicating that the parameters corresponding to the HT-Immediate BA Mode field in the restricted operation parameter field are not allowed to be adjusted.

[0411] The HT-Immediate BA Mode subfield indicates whether all HT-Immediate BA protocols are active or suspended when the STA is in restricted operation mode. For example, a value of 1 for the HT-Immediate BA Mode subfield indicates that all HT-Immediate BA protocols are active when the STA is in restricted operation mode; otherwise, it is set to 0.

[0412] It should be noted that the above-mentioned "1. First frame and first operation mode", "2. Operation parameters related to the first operation mode", "3. Interaction during parameter adjustment", "4. Application scenarios of parameter adjustment", and "5. Frame structure during parameter adjustment" can be implemented as independent embodiments or as combined embodiments. For example, the two interaction methods shown in "3.

Interaction during parameter adjustment" can be implemented in combination with the three application scenarios shown in "4. Application scenarios of parameter adjustment". That is, "Interaction Method 1: Notification" can be applied to the application scenario of "·Enabling the first operation mode", "Interaction Method 1: Notification" can be applied to the application scenario of "·Further adjusting operation parameters in the first operation mode", and "Interaction Method 1: Notification" can be applied to the application scenario of "·Disabling the first operation mode". Similarly, "Interaction Method 2: Negotiation" can be applied to the application scenario of "·Enabling the first operation mode", "Interaction Method 2: Negotiation" can be applied to the application scenario of "·Further adjusting operation parameters in the first operation mode", and "Interaction Method 2: Negotiation" can be applied to the application scenario of "·Disabling the first operation mode". Alternatively, the three application scenarios shown in "4. Application Scenarios for Parameter Adjustment" can all be implemented in combination with "1. First Frame and First Operation Mode" as a combined embodiment. That is, the three application scenarios can be performed on the first frame shown in "1. First Frame and First Operation Mode" or on the first operation mode. Alternatively, the three application scenarios shown in "4. Application Scenarios for Parameter Adjustment" can all be implemented in combination with "2. Operation Parameters Related to the First Operation Mode" as a combined embodiment. That is, the three application scenarios can be used to adjust the operation parameters shown in "2. Operation Parameters Related to the First Operation Mode".Alternatively, the three application scenarios shown in "4. Application Scenarios for Parameter Adjustment" can all be implemented as combined embodiments with "5. Frame Structure in the Parameter Adjustment Process," meaning that the three application scenarios can be implemented using the frame structure shown in "5. Frame Structure in the Parameter Adjustment Process." Furthermore, the methods shown above can also be combined in pairs, in groups of three or four, or all methods can be used as a combined embodiment. For example, the two interaction methods shown in "3. Interaction in the Parameter Adjustment Process" can both be implemented as combined embodiments with "1. First Frame and First Operation Mode" and "2. Operation Parameters Related to the First Operation Mode," meaning that the two different interaction methods can be performed on the first frame shown in "1. First Frame and First Operation Mode," or on the first operation mode, and can also be used to adjust the operation parameters shown in "2. Operation Parameters Related to the First Operation Mode." Alternatively, both interaction methods shown in "3. Interaction during parameter adjustment" can be implemented as combined embodiments with "1. First frame and first operation mode" and "5. Frame structure during parameter adjustment". That is, the two different interaction methods can be performed on the first frame shown in "1. First frame and first operation mode" or on the first operation mode, and the frame structure shown in "5. Frame structure during parameter adjustment" can be used for interaction. Alternatively, both interaction methods shown in "3. Interaction during parameter adjustment" can be implemented as combined embodiments with "2. Operation parameters related to the first operation mode" and "5. Frame structure during parameter adjustment". That is, the two different interaction methods can be used to adjust the operation parameters shown in "2. Operation parameters related to the first operation mode", and the frame structure shown in "5. Frame structure during parameter adjustment" can be used for interaction.Alternatively, in addition to the two interaction methods shown in "3. Interaction during parameter adjustment", and the three application scenarios shown in "4. Application scenarios of parameter adjustment", it can also be combined with at least one of "1. First frame and first operation mode", "2. Operation parameters related to the first operation mode", and "5. Frame structure during parameter adjustment". That is, "Interaction method one: notification" can be applied to the application scenario of "· Enabling the first operation mode", "Interaction method one: notification" can be applied to the application scenario of "· Further adjusting operation parameters in the first operation mode", and "Interaction method one: notification" can be applied to the application scenario of "· Not enabling the first operation mode". The "Interaction Method Two: Negotiation" can also be applied to the application scenario of "Enabling the First Operation Mode", the application scenario of "Further Adjusting Operation Parameters in the First Operation Mode", and the application scenario of "Disabling the First Operation Mode". In these application scenarios, it can be performed on the first frame shown in "1. The First Frame and the First Operation Mode" or on the first operation mode; and / or, the operation parameters shown in "2.

Operation Parameters Related to the First Operation Mode", "3. Interaction During Parameter Adjustment", "4. Application Scenarios for Parameter Adjustment", and "5. Frame Structure During Parameter Adjustment", can be implemented in combination. That is, in the six application scenarios of different interaction modes combined with "3.

[0413] Figure 15 shows a structural block diagram of a first device provided in an exemplary embodiment of this application. The first device can be implemented as an STA, or as part of an STA, through software or hardware, or a combination of both. The first device 400 includes:

[0414] The first transceiver module 410 is used to receive and / or send a first frame, the first frame being used to indicate whether a first operating mode is enabled, and / or to adjust operating parameters related to the first operating mode.

[0415] The first operating mode is at least one of the following: restricted operating mode; receiving capability adjustment operating mode; transmitting capability adjustment operating mode; receiving and transmitting capability adjustment operating mode; operating mode related to coexistence operation; and operating mode under interference scenarios.

[0416] In some embodiments, the first transceiver module 410 includes a first receiving unit and / or a first transmitting unit. The first receiving unit is used to perform receiving steps related to the first transceiver module 410; the first transmitting unit is used to instruct transmitting steps related to the first transceiver module 410.

[0417] In some embodiments, the first transmitting unit is configured to transmit a first frame, the first frame being used to enable a first operating mode; or, transmit a first frame, the first frame being used to adjust operating parameters related to the first operating mode; or, transmit a first frame, the first frame being used to disable the first operating mode; or, transmit a first frame, the first frame being used to indicate enabling the first operating mode and adjusting operating parameters related to the first operating mode; or, transmit a first frame, the first frame being used to indicate disabling the first operating parameters and adjusting operating parameters related to the first operating mode.

[0418] In some embodiments, the first receiving unit is configured to receive a first frame, the first frame being used to enable a first operating mode; or, receive a first frame, the first frame being used to adjust operating parameters related to the first operating mode; or, receive a first frame, the first frame being used to disable the first operating mode; or, receive a first frame, the first frame being used to indicate enabling the first operating mode and adjusting operating parameters related to the first operating mode; or, receive a first frame, the first frame being used to indicate disabling the first operating parameters and adjusting operating parameters related to the first operating mode.

[0419] In some embodiments, enabling the first operating mode can also be referred to as entering the first operating mode, or as turning on the first operating mode, or as adjusting the operating parameters to the operating parameters corresponding to the first operating mode.

[0420] In some embodiments, disabling the first operating mode can be referred to as exiting the first operating mode, or as closing the first operating mode. It can also be understood as adjusting the operating parameters to the operating parameters corresponding to the second operating mode. The second operating mode can be an unrestricted operating mode, or a normal operating mode, or an operating mode unrelated to coexisting operations, or an operating mode in an undisturbed scenario, or an operating mode before entering the restricted operating mode, etc.

[0421] In some embodiments, adjusting the operating parameters related to the first operating mode can be understood as a further adjustment of the operating parameters under the first operating mode, such as adjusting the operating parameters from the first operating parameters corresponding to the first operating mode to the second operating parameters corresponding to the first operating mode. It can also be understood as an adjustment to the first operating mode, such as changing from the receiving capability adjustment operating mode to the transmitting and receiving capability adjustment operating mode.

[0422] In some embodiments, adjusting the operating parameters related to the first operating mode can also be replaced by an equivalent description such as updating the operating parameters related to the first operating mode, and this application embodiment does not limit this.

[0423] In some embodiments, the receiving capability adjustment operation mode may also be referred to as the receiving capability limited operation mode or other equivalent names; the transmitting capability adjustment operation mode may also be referred to as the transmitting capability limited operation mode or other equivalent names; the receiving and transmitting capability adjustment operation mode may also be referred to as the receiving and transmitting capability limited operation mode or other equivalent names.

[0424] In some embodiments, operating parameters refer to parameters related to the operational capability of the first device. Operating parameters may also be referred to as communication parameters, transmit / receive parameters, or other equivalent terms. This application does not limit this to specific terms.

[0425] In some embodiments, adjusting the operating parameters related to the first operating mode may involve adjusting the operating parameters related to the first operating mode to a target parameter value; or it may involve enabling the operating parameters related to the first operating mode and their corresponding parameter values. That is, different operating modes may correspond to the same operating parameters, but the parameter values ​​of the operating parameters may be different in different operating modes; different operating modes may correspond to different operating parameters; or different operating modes may share some operating parameters, but there may also be one or more operating parameters that can be used independently by different operating modes.

[0426] In some embodiments, the operating parameters associated with the first operating mode can be understood as the operating parameters corresponding to the first operating mode, and / or, the operating parameters corresponding to the second operating mode, etc. The second operating mode is an operating mode different from the first operating mode. Adjusting the operating parameters to the operating parameters corresponding to the first operating mode can be understood as entering the first operating mode after adjustment, or switching from another operating mode to the first operating mode, where the other operating mode can be the second operating mode; adjusting the operating parameters to the operating parameters corresponding to the second operating mode can be understood as entering the second operating mode after adjustment, or switching from another operating mode (such as the first operating mode) to the second operating mode, which can also be said to be exiting another operating mode (such as the first operating mode).

[0427] In some embodiments, the first frame is further used for the second device to enable the first operating mode, and / or disable the first operating mode, and / or adjust operating parameters related to the first operating mode. The second device is a device associated with the first device. The second device may also be referred to as a device that shares one or more links with the first device; or in other words, the second device is a device that shares one or more links with the first device.

[0428] In summary, the device provided in this application embodiment illustrates a first device for adjusting parameters for a first operating mode. This device supports enabling or disabling the first operating mode. This process is performed by transmitting and receiving a first frame, thus clarifying the signaling interaction during the parameter adjustment process for the first operating mode and improving the adjustment efficiency of the parameter adjustment method for the first operating mode. The first frame avoids transmission failures and conflicts caused by untimely adjustment of operating parameters, improving communication efficiency and reliability. Furthermore, adjusting operating parameters via the first frame allows the first device to enter or exit the first operating mode. This first operating mode is at least one of a restricted operating mode, a receive capability adjustment operating mode, a transmit capability adjustment operating mode, a transmit / receive capability adjustment operating mode, an operating mode related to coexistence operation, or an operating mode under interference scenarios. Entering the first operating mode can avoid coexistence interference caused by multiple links operating simultaneously, which affects signal quality and data transmission reliability. In other words, entering the first operating mode effectively reduces such coexistence interference, improving the stability and performance of data transmission. In other situations where there is no coexistence interference, the utilization rate of the link can be improved by having the first device exit the first operating mode in the first frame, thereby improving data transmission efficiency.

[0429] Figure 16 shows a structural block diagram of a second device provided in an exemplary embodiment of this application. The second device can be implemented as an AP, or as part of an AP, through software or hardware, or a combination of both. The second device 500 includes:

[0430] The second transceiver module 510 is used to receive and / or send a first frame, the first frame being used to indicate whether a first operating mode is enabled, and / or to adjust operating parameters related to the first operating mode.

Operating parameters may also be referred to as communication parameters, transmit / receive parameters, or other equivalent terms. This application does not limit this to specific terms.

[0441] In some embodiments, adjusting the operating parameters related to the first operating mode may involve adjusting the operating parameters related to the first operating mode to a target parameter value; or it may involve enabling the operating parameters related to the first operating mode and their corresponding parameter values. That is, different operating modes may correspond to the same operating parameters, but the parameter values ​​of the operating parameters may be different in different operating modes; different operating modes may correspond to different operating parameters; or different operating modes may share some operating parameters, but there may also be one or more operating parameters that can be used independently by different operating modes.

[0442] In some embodiments, the operating parameters associated with the first operating mode can be understood as the operating parameters corresponding to the first operating mode, and / or, the operating parameters corresponding to the second operating mode, etc. The second operating mode is an operating mode different from the first operating mode.

[0443] In some embodiments, the first frame is further used for the second device to adjust operating parameters related to the first operating mode. The second device is a device associated with the first device. The second device may also be referred to as a device that shares one or more links with the first device; or, in other words, the second device is a device that shares one or more links with the first device.

[0444] In summary, the device provided in this application embodiment illustrates a second device for adjusting parameters in a first operating mode. This device supports enabling or disabling the first operating mode. This process is performed by transmitting and receiving a first frame, thus clarifying the signaling interaction during the parameter adjustment process for the first operating mode and improving the adjustment efficiency of the parameter adjustment method for the first operating mode.

[0445] The following section will introduce the first frame and the first operation mode.

[0446] 1. The first frame and the first operation mode.

[0447] For details, please refer to "1. First Frame and First Operation Mode" in the above method embodiment, which will not be repeated here.

[0448] 2. Operating parameters related to the first operating mode.

[0449] For details, please refer to "2. Operation parameters related to the first operation mode" in the above method embodiment, which will not be repeated here.

[0450] 3. Interaction during parameter adjustment.

[0451] For details, please refer to "3. Interaction during parameter adjustment" in the above method embodiment, which will not be repeated here.

[0452] In some embodiments, the operating parameters are parameters used for communication between the first device and the second device, or parameters used for communication between a station attached to the first device and a station attached to the second device. Since the stations attached to the first device and the second device, operating on the same link, support communication, adjusting the operating parameters requires joint execution by the related stations. Therefore, when one of the stations attached to the first device or the second device needs to enter or exit a first operating mode, it needs to instruct its corresponding peer station on the appropriate parameter adjustment operation, such as the operating parameters to be adjusted, the adjusted parameter values, etc. The party initiating the parameter adjustment can be called the initiator, and the peer station can be called the responder. After receiving the parameter adjustment operation instructed by the initiator, the responder needs to execute the parameter adjustment operation accordingly to ensure normal communication between the initiator and the responder, or, based on its own capabilities and configuration, inform the initiator whether it can execute the corresponding parameter adjustment operation, when to end the parameter adjustment operation, etc. To reduce signaling interactions during parameter adjustment and avoid issues such as data packet loss and reduced transmission efficiency due to the responder's inability to perform parameter adjustment operations in a timely manner, at least one of the following interaction methods shown in the embodiments of this application can be used (the order of description does not represent the superiority or inferiority of the interaction methods).

[0453] Interaction Method 1: Notification.

[0454] Interaction Method Two: Negotiation.

[0455] Notification involves the initiator informing the responder that a parameter adjustment operation needs to be performed, and the responder, upon receiving the notification frame from the initiator, should adjust the operation parameters accordingly. Negotiation involves the initiator requesting the responder to perform a parameter adjustment operation, and the responder, based on its own capabilities and configuration, negotiating with the initiator which parameters can be adjusted and which cannot, thus arriving at an adjustment plan for the operation parameters agreed upon by both the initiator and the responder. The following section describes the interaction process and content for these two interaction methods, using a second device and a first device as examples.

[0456] Interaction Method 1: Notification.

[0457] In the notification interaction method, the responder (second device or first device) can inform the initiator (first device or second device) in advance whether it supports adjusting operating parameters, the range of adjustment, etc. Alternatively, this advance notification process can be skipped, and the initiator (second device or first device) can directly notify the responder (first device or second device) how to adjust the operating parameters when it needs to perform the parameter adjustment operation. These two notification methods will be described in detail below.

[0458] (1) No prior notification process.

[0459] In some embodiments, the first frame is sent from the first device to the second device; or, the first frame is sent from the second device to the first device.

The first adjustment module is configured to, based on the first frame, adjust the operating parameters related to the first operating mode in one or more sites attached to the first device when a conversion timeout period is reached at a first time; wherein the first time begins at a first moment, and the first moment is related to the acknowledgment frame of the first frame. The acknowledgment frame of the first frame refers to the acknowledgment frame sent by the second device to the first device after the second device receives the first frame sent by the first device. This acknowledgment frame is used to indicate that the second device has received the first frame sent by the first device.

[0463] ② Actions on the second equipment side.

[0464] In some embodiments, the second device 500 further includes a second adjustment module. The second adjustment module is configured to, before the second time reaches a conversion timeout period, adjust operating parameters related to the first operating mode in one or more sites attached to the second device based on a first frame; or, if the second time reaches a conversion timeout period, adjust operating parameters related to the first operating mode in one or more sites attached to the second device based on a first frame; wherein the second time begins at a first moment, and the first moment is related to the confirmation frame of the first frame.

[0465] It should be noted that the interaction process in the above scenario one is illustrated by the example of the first device sending the first frame and the second device receiving the first frame. That is, the first device, based on its own capabilities, environment, and currently executed services, determines that it should adjust the operating parameters related to the first operating mode to adapt to the above requirements. Then, the first device notifies the second device to perform the adjustment of the operating parameters related to the first operating mode to ensure communication between the first and second devices. However, it is also possible that the second device, based on its own capabilities, environment, and currently executed services, determines that the first device should adjust the operating parameters related to the first operating mode to adapt to the above requirements. Then, the second device notifies the first device to perform the adjustment of the operating parameters related to the first operating mode.

[0468] In some embodiments, the first moment is the end of the PPDU carrying the acknowledgment frame; or, the first moment is the end of the signal extension following the PPDU carrying the acknowledgment frame. Alternatively, the first moment is the end of the PPDU carrying the acknowledgment frame of the first frame; or, the first moment is the end of the signal extension following the PPDU carrying the acknowledgment frame of the first frame. It can also be said that the first moment is the end time of the PPDU carrying the acknowledgment frame of the first frame; or, the first moment is the end time of the signal extension following the PPDU carrying the acknowledgment frame of the first frame. Alternatively, for the first device, the first moment is the end time of sending the PPDU carrying the acknowledgment frame of the first frame; or, the first moment is the signal following the PPDU carrying the acknowledgment frame of the first frame. For the second device, the first moment is the end time of receiving the PPDU carrying the acknowledgment frame of the first frame; or, the first moment is the signal following the PPDU carrying the acknowledgment frame of the first frame.

[0469] ·Scenario 2.

[0470] ① Actions on the first equipment side.

[0471] In some embodiments, the first transceiver module 410 is configured to send a first frame to the second device. The first transceiver module 410 is configured to receive a second frame sent by the second device, the second frame being used in response to the first frame; send an acknowledgment frame for the second frame to the second device; and a first adjustment module is configured to, at a second time, based on the first frame, adjust operating parameters related to a first operating mode in one or more sites attached to the first device, the second time being related to the acknowledgment frame of the second frame.

[0472] ② Actions on the second equipment side.

[0473] In some embodiments, the second transceiver module 510 is configured to receive a first frame sent by the first device. Optionally, the second transceiver module 510 is configured to send a second frame to the first device, the second frame being used in response to the first frame; receive an acknowledgment frame from the first device for the second frame; and a second adjustment module is configured to, at a second time, based on the first frame, adjust operating parameters related to the first operating mode in one or more sites attached to the second device, the second time being related to the acknowledgment frame of the second frame.

[0474] It should be noted that the interaction process in the above scenario two is illustrated by the example of the first device sending the first frame and the second device receiving the first frame. That is, the first device, based on its own capabilities, environment, and currently executed services, determines that it should adjust the operating parameters related to the first operating mode to adapt to the above requirements. Then, the first device notifies the second device to perform the adjustment of the operating parameters related to the first operating mode to ensure communication between the first and second devices. However, it is also possible that the second device, based on its own capabilities, environment, and currently executed services, determines that the first device should adjust the operating parameters related to the first operating mode to adapt to the above requirements. Then, the second device notifies the first device to perform the adjustment of the operating parameters related to the first operating mode. That is, the second device sends the first frame and the first device receives the first frame.

[0475] In some embodiments, the first transceiver module 410 is configured to receive a first frame sent by the second device. Optionally, the first transceiver module 410 is configured to send a second frame to the second device, the second frame being used in response to the first frame; receive an acknowledgment frame from the second device for the second frame; and a first adjustment module is configured to, at a second time, based on the first frame, adjust operating parameters related to a first operating mode in one or more sites attached to the first device, the second time being related to the acknowledgment frame of the second frame.

[0476] In some embodiments, the second transceiver module 510 is configured to send a first frame to the first device.

[0477] It should be noted that Scenarios 1 and 2 described above can be implemented as independent embodiments or as combined embodiments. That is, only a conversion timeout is set, and the first and second devices should adjust the operating parameters when the conversion timeout is reached in the first time; or, it is agreed that the adjustment time is confirmed based on the second frame, i.e., the first and second devices confirm the second time based on the confirmation frame for the second frame, and adjust the operating parameters in the second time. However, in some optional embodiments, Scenarios 1 and 2 can be implemented in combination, i.e., both a conversion timeout is set and it is agreed that a second frame can be sent to confirm the adjustment time. Specifically, the first device and / or the second device adjust the operating parameters related to the first operating mode in a third time, based on the first frame. The third time is the earlier of the first time when the conversion timeout is reached and the second time.

[0478] That is, for the first device and / or the second device, there are two scenarios: The first adjustment module and / or the second adjustment module are configured to adjust the operating parameters related to the first operating mode based on the first frame when the conversion timeout period is reached, provided that no second frame is received, no second frame is sent, no acknowledgment frame is received, or no acknowledgment frame is sent before the first conversion timeout period is reached. Alternatively, if a second frame is received, sent, or an acknowledgment frame is received, or an acknowledgment frame is sent before the first conversion timeout period is reached, a second moment is determined; and at the second moment, the operating parameters related to the first operating mode are adjusted based on the first frame. In this case, the time between the first moment and the second moment is less than the conversion timeout period, meaning the second moment is the moment before the first conversion timeout period is reached.
