For example, when the first communication device 101 is a non-AP STA, the second communication device 102 is a UHR mobile AP.
[0128] In some embodiments, the first device 101 and the second device 102 comprise, for example, a wireless communication chip supporting WiFi communication function, a wireless sensor, or a wireless communication terminal. Optionally, the wireless communication terminal is at least one of a mobile phone, a wearable device, an Internet of Things (IoT) device supporting WiFi communication function, a WiFi communication function-equipped vehicle, a smart vehicle, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in smart grid, a wireless terminal device in transportation safety, a wireless terminal device in smart city, a wireless terminal device in smart home, but not limited thereto.
[0129] Specifically, the first device 101 and the second device 102 can be a terminal device or a network device with a wireless fidelity (WiFi) chip. Optionally, the first device 101 and the second device 102 can support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, 802.11bn, and the next generation 802.11 protocol, but not limited thereto.
[0130] In some embodiments, the first device 101 and the second device 102 can be an access point (AP) for a mobile terminal to access a wired network. The AP serves as a bridge connecting the wired network and the wireless network, and its main function is to connect various wireless network clients together and then access the Ethernet network through the wireless network. Specifically, the AP can be a terminal device or a network device with a wireless fidelity chip. Optionally, the AP can support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, 802.11bn, and the next generation 802.11 protocol, but not limited thereto.
[0131] Optionally, in the embodiments of the present disclosure, the AP and the STA can be devices supporting multi-link, for example, can be respectively denoted as an access point multi-link device (AP MLD) and a non-access point multi-link device (Non-AP MLD); the AP MLD can represent an access point supporting a multi-link communication function, and the non-AP MLD can represent a station supporting a multi-link communication function.
[0132] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions proposed in the embodiments of the present disclosure. It can be known by those skilled in the art that, as the system architecture evolves and new business scenarios appear, the technical solutions proposed in the embodiments of the present disclosure are also applicable to similar technical problems.
[0133] The following embodiments of the present disclosure can be applied to the communication system 100 shown in FIG. 1 or part of the subjects, but are not limited thereto. The subjects shown in FIG. 1 are exemplary, and the communication system can include all or part of the subjects in FIG. 1, or other subjects other than FIG. 1.

[0134] Embodiments of the present disclosure can be applied to a wireless local area network (WLAN), for example, a local area network using 802.11 series protocols. In a WLAN, a basic service set (BSS) is a basic component of a WLAN. A BSS network is composed of a group of station devices having some association within a certain coverage area. One case of association is that the stations directly communicate with each other in an ad hoc network, which is referred to as an independent BSS (IBSS). Another more common case is that in a BSS network, there is only one central station with a full-time management BSS, which is referred to as an access point device, and the other STAs in the network are associated with it. The other stations in the BSS network that are not the central station are referred to as terminals, also referred to as non-AP STAs. When describing a STA, it is not necessary to distinguish between AP and non-AP STAs. In the same BSS network, due to distance, transmission power, etc., a STA cannot detect other STAs far away from it, and the two are each other's hidden nodes.
[0135] FIG. 2 is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2, the above method includes:
[0136] In step 201, the first device 101 determines a first wireless frame in an initial association process with the second device 102; wherein the first wireless frame includes first identification information, and the first identification information identifies the first device 101: support capability information between different capability communication modes.
[0137] In a Wi-Fi network, a station device usually needs to communicate with an access point device periodically to maintain the connection, even when the device has no data to send or receive. This communication mode can cause the device to have high energy consumption in the standby state. To solve this problem, a power saving (PS) enhancement mechanism is proposed, which allows the device to enter a low energy mode for a period of time and temporarily stop receiving data frames, thereby reducing the energy consumption of the device. For example, the device may take some power saving measures during the idle period or low load condition to reduce the power consumption of the device. In this case, the device needs to switch to a low energy mode with lower power consumption to reduce energy consumption and prolong battery life. When the device needs to perform a large amount of data transmission, video streaming or other high-bandwidth applications, it may switch to a high energy mode with higher power consumption to provide higher transmission rate and more stable connection.
[0138] The related art introduces a dynamic spatial multiplexing mode, i.e., a device listens in a single spatial stream (1SS) and communicates in multiple spatial streams (SS), which can achieve the purpose of improving communication efficiency at low energy consumption to a certain extent; it can also be static SM, i.e., consistent 1SS listening and 1SS sending, wherein the modulation and coding scheme (MCS) mode of the two is indefinite, such as from MCS0 to MCS13, etc. However, the aforementioned SM mode cannot flexibly save power, for example, in the dynamic SM, there may be a large MCS mode in the listening stage, which consumes a large amount of power. However, in UHR, some applications may not require large communication parameters, such as high BW and high-order MCS mode, etc. In order to flexibly meet the needs, a new signaling process needs to be defined to help the device flexibly adjust the communication mode under different needs, so as to reduce the power consumption of the device, make it suitable for UHR needs, and ensure efficient data transmission in various network environments.
[0139] In the embodiments of the present disclosure, a first device determines a first radio frame in an initial association process with a second device; wherein the first radio frame includes first identification information, and the first identification information identifies support capability information of the first device for switching between different communication modes. Different communication modes may, for example, include a first capability communication mode, a second capability communication mode, or more communication modes divided according to different requirements for device capability; the first capability communication mode may, for example, be a low-energy communication mode, and the second capability communication mode may, for example, be a high-energy communication mode; optionally, the low-energy communication mode can also be referred to as a listening state or a low-power communication stage, for example, the working parameter is a 20MHz basic bandwidth, the number of SS is 1, and the MCS mode is, for example, from MCS0 to MCS6. The high capability mode refers to a high-power communication mode, for example, the working parameter is greater than or equal to 20MHz, the BW can also be 40 / 80 / 160 / 320MHz, the number of SS is greater than or equal to 2, and the MCS mode is, for example, from MCS6 to MCS14, etc.
[0140] Alternatively, at least one communication parameter in the second capability communication mode is greater than the communication parameter in the first capability communication mode; the communication parameter includes one or more of a bandwidth (Bandwidth, BW), a number of spatial streams (Number of spatial streams, NSS), an MCS mode, and a transmission rate.
[0141] Specifically, the first identification information can include one identification bit for indicating whether the first device supports switching between different capability communication modes. In addition, the first identification information can further include two identification bits for respectively indicating whether the first device supports a high-energy communication mode (hereinafter referred to as a second capability communication mode) and a low-energy communication mode (hereinafter referred to as a first capability communication mode). The first identification information can help the second device to understand the support capability of the first device for switching between different capability communication modes, so as to make corresponding adjustments in the communication process. The second capability communication mode can be a mode adopted by the device when the device needs more frequent data transmission or higher rate communication, and the first capability communication mode can be an energy saving strategy adopted by the device in some cases to reduce energy consumption and prolong battery life. For example, the high-energy communication mode is an active mode (Active Mode) or an awake mode (Awake Mode), and the low-energy communication mode is a doze mode (Doze Mode).
[0142] In addition, the first device can be a station device (Station, STA) or an access point device (Access Point, AP), and the second device can be a STA or an AP. For example, when the first device 101 is a STA, the second device 102 is an AP or a non-AP MLD. The station device includes a non-AP STA affiliated to a non-AP MLD, and the access point device includes a UHR mobile AP. For example, when the first device 101 is a non-AP STA, the second device 102 is a UHR mobile AP.
[0143] Specifically, if the device cannot effectively switch between different capability communication modes, it can cause long-time running in the high-energy communication mode, thereby increasing the energy consumption of the device.
[0144] In the embodiments of the present disclosure, the first device can transmit support capability information to the second device in the initial association process according to its own communication capability and supported different capability communication modes, so as to help the second device to better understand the support capability of the first device for switching between different capability communication modes. In this way, the second device can make more reasonable decisions according to the support capability information of the first device, thereby maximizing the reduction of its own energy consumption without affecting the communication quality.
[0145] Step 202, the first device 101 sends the first wireless frame.
[0146] In the embodiments of the present disclosure, the first device sends a first wireless frame in an initial association process with the second device. When the first device comprises a station device (for example, the first device is a Non-AP STA), the first wireless frame comprises at least one of the following:
[0147] a probe request frame, an association request frame, and a reassociation request frame.
[0148] When the first device is a Non-AP STA, sending the probe request frame, the association request frame, or the reassociation request frame to identify the support capability information of the first device for the communication mode switching of different energies is helpful for the UHR mobile AP to adjust the communication mode according to the actual situation, thereby optimizing the energy utilization and reducing the power consumption in the initial association process.
[0149] When the first device comprises an access point device (for example, the first device is a UHR mobile AP or an AP or an AP MLD), the first wireless frame comprises at least one of the following:
[0150] a beacon frame, a probe response frame, an association response frame, and a reassociation response frame; wherein the first identification information is carried in an ultra-high reliability capability (UHR capabilities) information element of the first wireless frame.
[0151] When the first device is a UHR mobile AP, sending the probe request frame, the association request frame, or the reassociation request frame to identify the support capability information of the first device for the communication mode switching of different energies is helpful for the Non-AP STA to adjust the communication mode according to the actual situation, thereby optimizing the energy utilization and reducing the power consumption in the initial association process.
[0152] In some embodiments, if the Non-AP STA is attached to a Non-AP MLD, or the UHR mobile AP is attached to a Non-AP MLD, the support capability information of the communication mode switching of different energies identified by the first identification information is at a Multi-Link Device (MLD) level.
[0153] In step 203, the second device 102 receives the first wireless frame sent by the first device 101 in the initial association process with the first device 101, wherein the first wireless frame comprises first identification information, and the first identification information identifies the support capability information of the first device 101 for switching between communication modes of different capabilities.
[0154] In the embodiments of the present disclosure, the second device receives the first wireless frame in the initial association process with the first device, and learns the support capability information of the first device for switching between communication modes of different capabilities according to the first identification information carried in the first wireless frame. In this way, the second device can make a more reasonable decision according to the support capability information of the first device, thereby reducing the energy consumption of the second device to the greatest extent without affecting the communication quality.
[0155] In step 204, the first device 101 switches to the first capability communication mode for communication after the initial association is completed, and / or the first device 101 supports an enhanced Multi-Link Single Radio (eMLSR) mode or an enhanced Multi-Link Multi-Radio (eMLMR) mode, and switches to the first capability communication mode for communication in each link.
[0156] In the embodiments of the present disclosure, after the initial association is completed, if the first device supports switching between communication modes of different capabilities, the first device directly switches to the first capability communication mode for communication, that is, the first device performs listening in the low capability communication mode. Switching of the first device to the first capability communication mode can reduce the power consumption of the device, prolong the endurance time of the device, reduce the battery consumption, and save energy. If the first device maintains the high energy communication mode in the initial association process, it may cause high power consumption, shorten the endurance time, and increase the battery consumption. Therefore, in the embodiments of the present disclosure, after the initial association is completed, if the first device supports switching between communication modes of different capabilities, the first device directly switches to the first capability communication mode for communication, which is helpful for optimizing energy management and reducing the power consumption of the device. For example, the first device is in the first capability communication mode, the bandwidth of the first device is set to 20 MHz, the number of spatial streams is 1, and the first device uses the lowest MCS mode (for example, MCS 0 or MCS 1) for transmission, and the corresponding transmission rate is 6 Mbps, to adapt to the requirements in the first capability communication mode.
[0157] In some embodiments, the eMLSR or eMLMR mode allows a single device to simultaneously use multiple links for communication, and if the first device supports the eMLSR or eMLMR mode, the first device switches to the first capability communication mode for communication in each link, which can reduce the power consumption of the device and also reduce the impact of link failure on the entire network.
[0158] As an example, referring to FIG. 3, which shows an optional implementation of an embodiment of the present disclosure, including the following steps:
[0159] In step 301, the first device 101 receives an initial control frame sent by the second device 102 in the first capability communication mode; the initial control frame includes communication parameters in the second capability communication mode; at least one communication parameter in the second capability communication mode is greater than the communication parameter in the first capability communication mode.
[0160] The communication parameters include one or more of BW, NSS, MCS mode, transmission rate, etc.
[0161] In an embodiment of the present disclosure, when the network load increases or the user demand changes, a higher transmission rate or a lower delay may be required. The second device sends a second wireless frame to inform the first device to switch to a high-energy communication mode, for example, the second capability communication mode, to meet the above requirements. Or, in the case of a large signal coverage range, the second device may need to use a high-energy communication mode to ensure good signal transmission quality and stability. The second device sends a second wireless frame to inform the first device to switch to the second capability communication mode to improve the communication coverage range.
[0162] In an embodiment of the present disclosure, the first device accepts the initial control frame sent by the second device in the first capability communication mode. The initial control frame may be, for example, a multi-user request to send (MU-RTS) frame, a buffer status report poll (BSRP) frame, or other frames, etc., or a newly defined frame.
[0163] The initial control frame comprises a communication parameter in the second capability communication mode; wherein at least one communication parameter in the second capability communication mode is greater than the communication parameter in the first capability communication mode, indicating that the second device needs to use the second capability communication mode with higher energy for communication. The first device receives the initial control frame, and determines whether it needs to switch to the second capability communication mode for communication according to the communication parameter carried in the initial control frame to meet the current communication requirement. For example, the first device is in the first capability communication mode, and the BW is set to 20MHz. When the second device needs to use the second capability communication mode to ensure good signal transmission quality and stability, the second device sends the initial control frame, and carries the BW set to 40MHz or higher in the second capability communication mode in the initial control frame.
[0164] In step 302, the first device 101 sends a first confirmation message frame to the second device 102 in the first capability communication mode; the first confirmation message frame identifies that the first device 101 switches to the second capability communication mode for communication.
[0165] In the embodiment of the present disclosure, the first device sends a first confirmation message frame to the second device in the first capability communication mode, and identifies that the first device switches to the second capability communication mode for communication. If the BW parameters in the first capability communication mode and the second capability communication mode are the same, the first device and the second device do not need to initiate a Request to Send (RTS) / Clear to Send (CTS) process before the first device switches to the second capability communication mode for communication. This means that the first device and the second device can directly communicate, saving additional delay and bandwidth consumption in the communication process. If the BW parameters in the first capability communication mode and the second capability communication mode are different, it means that the BW parameter needs to be adjusted, and the first device receives an RTS frame from the second device and sends a CTS frame. This process ensures the adjustment of the communication parameter and the consistency of the communication parties, and provides the necessary confirmation for the first device to switch to the second capability communication mode.
[0166] In step 303, the second device 102 receives the first confirmation message frame sent by the first device 101 in the first capability communication mode; the first confirmation message frame identifies that the first device 101 switches to the second capability communication mode for communication.
[0167] In the embodiment of the present disclosure, the first device sends a first acknowledgement message frame to the second device in the first capability communication mode, indicating that the first device has prepared and has switched to the second capability communication mode, and can communicate in a higher communication capability.
[0168] As an example, referring to FIG. 4, FIG. 4 shows an optional implementation of an embodiment of the present disclosure, including the following steps:
[0169] In step 401, the first device 101 receives a data frame sent by the second device 102; the second identification information of the data frame identifies that the support capability information for switching between communication modes with different capabilities of the second device 102 is a first parameter.
[0170] In the embodiment of the present disclosure, in the process of communication between the first device and the second device in the second capability communication mode, the second device carries second identification information in a media access control (MAC) frame header in the last data frame of the data transmission, and the second identification information identifies that the support capability information for switching between communication modes with different capabilities is a first parameter. For example, when the second identification information is set to the first parameter, it indicates that the second device switches to the first capability communication mode for communication.
[0171] In step 402, the first device 101 sends a second acknowledgement message frame to the second device and switches to the first capability communication mode; wherein the first identification information is included in the second acknowledgement message frame, and the first identification information is set to the first parameter.
[0172] In the embodiment of the present disclosure, if the second identification information is set to the first parameter, indicating that the second device switches to the first capability communication mode for communication, after receiving the data frame sent by the second device, the first device replies an acknowledgement (ACK) frame to the second device, indicating that the data frame has been received and is ready to switch to the first capability communication mode, and carries the first identification information in the MAC frame header of the ACK frame, and the first identification information is set to the first parameter, to ensure the consistency of the communication parameters between the first device and the second device, thereby avoiding the mismatch problem in communication.
[0173] In step 403, the second device 102 receives the second acknowledgement message frame sent by the first device 101, and the second acknowledgement message frame indicates that the first device 101 switches to the first capability communication mode for communication.
[0174] In step 403, the second device 102 receives the second acknowledgement message frame sent by the first device 101, and the second acknowledgement message frame indicates that the first device 101 switches to the first capability communication mode for communication.
[0175] In the embodiments of the present disclosure, the second device receives the second confirmation message frame sent by the first device, and the message indicates that the first device has successfully switched to the first capability communication mode for communication. In this case, the first identification information is included in the second confirmation message frame, and the information is set as the first parameter.
[0176] As an example, referring to FIG. 5, FIG. 5 shows an optional implementation of the embodiments of the present disclosure, including the following steps:
[0177] In step 501, the first device 101 sends a request frame to the second device 102, requesting to switch to the first capability communication mode for communication.
[0178] In some embodiments, in addition to transmitting the second identification information in the process of data transmission, the first device can also send a request frame requesting to switch to the first capability communication mode for communication according to the current communication environment. For example, if there is a large amount of interference or signal attenuation in the current communication environment, resulting in poor communication quality, the first device can request to switch to the first capability communication mode to reduce the requirement for signal quality. Or if the current communication task has a low requirement for communication rate, or is a periodic data transmission task, the first device can request to switch to the low capability communication mode to reduce the power consumption of the communication device and prolong the battery life. Or if the first device needs to make a trade-off in terms of battery life, for example, in the case of low battery, the first device can actively request to switch to the first capability communication mode to enter a more energy-saving mode and prolong the available time of the device.
[0179] In step 502, the second device 102 receives the request frame sent by the first device 101, requesting to switch to the first capability communication mode for communication.
[0180] In the embodiments of the present disclosure, after receiving the request frame sent by the first device, requesting to switch to the first capability communication mode for communication, the second device can decide whether to accept the first device to switch to the first capability communication mode for communication according to the current communication environment.
[0181] In step 503, the second device 102 sends a response frame to the first device 101.
[0182] In step 504, after receiving the response frame, the first device 101 switches to the first capability communication mode for communication.
[0183] In the embodiments of the present disclosure, after receiving the request, the second device sends a response frame as an acknowledgement, and the response frame can carry an identifier of whether the second device accepts the first device switching to the first capability communication mode for communication. If the second device accepts the first device switching to the first capability communication mode for communication, the first device switches to the first capability communication mode for communication after receiving the response frame. In this way, a mechanism for actively switching the communication mode is provided, so that the communication parties can more flexibly coordinate the communication process. Through the interaction of the request and the acknowledgement, the consistency and reliability of the communication parties when switching the communication mode can be ensured, so that the communication demand can be better met and the communication efficiency can be improved.
