[0037] This disclosure presents a power-saving negotiation method, communication equipment, and communication system.
[0038] In a first aspect, embodiments of this disclosure propose a power-saving negotiation method, the method comprising:
[0039] A non-AP STA (Multi-Connection Site Device) determines a first radio frame; wherein the first radio frame is used to request: setting one or more links with a multi-connection access point device (AP MLD) to a target communication mode; wherein the target communication mode is one of different capability communication modes;
[0040] The first wireless frame is transmitted on one of the links.
[0041] In the above embodiments, by sending a first wireless frame requesting one or more links to be set to the target communication mode on one link, frame exchange on each link with the AP MLD is avoided, reducing transmission latency and enabling efficient and fast switching of communication modes in multi-link scenarios to meet UHR transmission requirements.
[0042] In conjunction with some embodiments of the first aspect, in some embodiments, the first wireless frame includes at least one of the following:
[0043] The first identification information identifies whether the communication mode requested by the non-AP STA for the link is a first capability communication mode or a second capability communication mode;
[0044] The third identification information identifies the non-AP STA as the communication duration information requested by the link in the target communication mode;
[0045] In this second capability communication mode, at least one communication parameter is greater than the communication parameter in the first capability communication mode.
[0046] In the above embodiments, by including first identification information and second identification information in the first wireless frame, the communication mode requested by the non-AP STA for the link can be effectively managed, thereby achieving optimized wireless communication performance.

[0123] As shown in Figure 1, the communication system 100 includes a non-access point station (non-AP STA) 101 and an access point (AP) 102 attached to the access point multi-link device (AP MLD). The number of non-AP STAs 101 may be one or more, and this embodiment of the present disclosure is not limited thereto.
[0124] In some embodiments, the non-AP STA 101 may include, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports WiFi communication. Optionally, the wireless communication terminal may be at least one of, but is not limited to, a mobile phone, a wearable device, an IoT device that supports WiFi communication, a car with WiFi communication capabilities, a smart car, a tablet computer, a computer with wireless transceiver capabilities, 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 a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, or a wireless terminal device in a smart home.
[0125] Specifically, the non-AP STA 101 can be a terminal device or network device with a Wi-Fi chip. Optionally, the non-AP STA 101 can support various WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, and 802.11bn, as well as the next-generation 802.11 protocol, but is not limited to these.
[0126] In some embodiments, AP 102 can be an access point for mobile terminals to access a wired network. The AP acts as a bridge connecting wired and wireless networks, its main function being to connect various wireless network clients together and then connect the wireless network to the Ethernet. Specifically, the AP can be a terminal device or network device with a Wi-Fi chip.

[0127] Optionally, in this embodiment of the disclosure, AP and STA can be devices that support multiple connections. For example, they can be represented as Access Point Multi-Link Device (AP MLD) and Non-Access Point Multi-Link Device (Non-AP MLD), respectively. AP MLD can represent an access point that supports multiple connection communication functions, and non-AP MLD can represent a station that supports multiple connection communication functions.
[0128] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.
[0129] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.
[0130] The embodiments disclosed herein can be applied to Wireless Local Area Networks (WLANs), such as LANs using the 802.11 series of protocols. In a WLAN, a Basic Service Set (BSS) is a fundamental component. An BSS network consists of site devices with some association within a specific coverage area. One type of association is where sites communicate directly with each other in a self-organizing network; this is called an Independent Basic Service Set (IBSS). Another more common scenario is that in a BSS network, there is only one central site dedicated to managing the BSS, called the Access Point (AP) device, and all other STAs in the network are associated with it. Other sites in the BSS network that are not the central site are called terminals, also known as non-AP STAs; terminals and non-AP STAs are collectively referred to as STAs. When describing STAs, it is not necessary to distinguish between APs and non-AP STAs. Within the same BSS network, due to distance, transmission power, etc., a STA cannot detect other STAs that are far away; they are each other's hidden nodes.
[0131] Figure 2 is an interactive schematic diagram of a power-saving negotiation method according to an embodiment of the present disclosure. As shown in Figure 2, the method includes:
[0132] Step 201, non-AP STA 101 determines a first radio frame attached to the non-AP MLD; wherein the first radio frame is used to request: to set one or more links with the AP MLD to a target communication mode; wherein the target communication mode is one of different capability communication modes.
[0133] In Wi-Fi networks, site devices typically need to periodically communicate with access point devices to maintain connectivity, even when there is no data to send or receive. This communication method leads to higher power consumption in standby mode. To address this issue, power saving (PS) enhancement mechanisms have been proposed. These mechanisms allow devices to enter a low-power mode for a period of time, temporarily ceasing the reception of data frames, thereby reducing power consumption. For example, devices may take power-saving measures during idle periods or under low load to reduce power consumption. In this case, the device needs to switch to a lower-power mode to reduce energy consumption and extend battery life. When the device needs to perform large amounts of data transmission, video streaming, or other high-bandwidth applications, it may switch to a higher-power mode to provide higher transmission rates and a more stable connection.
[0134] To achieve higher throughput and lower network latency, related technologies have introduced the Multi-Link Operation (MLO) mechanism. Devices supporting MLO are called Multi-Link Devices (MLDs), or simply multi-connection devices. With MLO technology, multiple links can be established across frequency bands between multi-connection access point devices (AP MLDs) and multi-connection site devices (non-AP MLDs). In the multiple links established between AP MLDs and non-AP MLDs, the power-saving capabilities of each link are independent. The non-AP MLD needs to indicate the power management mode for each link separately. That is, when a non-AP MLD intends to enter a low-power mode (lower power consumption) or a high-power mode (higher power consumption) on multiple or even all links, frame switching needs to be performed on each enabled link. This method of switching communication modes by switching frames link by link increases the latency of the entire switching process, and some links may be idle during the switching process, failing to fully utilize bandwidth resources and thus reducing overall communication efficiency. Since UHRs are designed to improve the reliability of wireless LAN connections, reduce latency, and lower device-level power consumption, and most UHRs are designed as MLD devices, power-saving mechanisms need to be further enhanced when APs and STAs use multi-link methods for data transmission.
[0135] In this embodiment of the disclosure, the non-AP STA determines a first radio frame; wherein, the first radio frame is used to request: to set one or more links with the AP MLD to a target communication mode; the target communication mode is one of different capability communication modes. The first radio frame includes a Power Management (PM) request frame or a newly defined radio frame. Different capability communication modes include, for example, a first capability communication mode, a second capability communication mode, or more communication modes classified according to different requirements for device capabilities. The first capability communication mode is, for example, a low-energy communication mode, and the second capability communication mode is, for example, a high-energy communication mode; optionally, the low-energy communication mode may also be referred to as a listening state or a low-power communication phase. Operating parameters under the low-energy communication mode include: a 20MHz basic bandwidth (BW), a spatial stream (SS) count of 1, and a restricted modulation and coding scheme (MCS) method, for example, from MCS0 to MCS5. High-capability mode refers to high-power communication mode. Operating parameters include: BW greater than or equal to 20MHz, for example, 40 / 80 / 160 / 320MHz; SS quantity greater than 1; and MCS mode starting value is the highest value of low-capability communication mode MCS mode, for example, from MCS5 to MCS14.
[0136] 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 parameters include one or more of BW, SS, MCS modes and transmission rates.
[0137] Specifically, in the multiple links established between AP MLDs and non-AP MLDs, each link may have different requirements. For example, one or more links between a non-AP MLD and an AP MLD may need to remain active, while some links may need to enter a low-power mode to save energy. In this case, if the non-AP MLD performs frame switching on each link with the AP MLD to request the corresponding link to enter the target communication mode, it will introduce additional transmission latency, reducing the overall system efficiency and network throughput.
[0138] In this embodiment of the disclosure, the non-AP STA determines a first radio frame; wherein, the first radio frame is used to request: setting one or more links with the AP MLD to a target communication mode; wherein, the target communication mode is one of communication modes with different capabilities. This embodiment of the disclosure avoids separate frame switching on each link with the AP MLD by sending a first radio frame requesting one or more links to be set to the target communication mode on a single link, reducing transmission latency and achieving efficient and fast switching of communication modes in multi-link scenarios, adapting to UHR transmission requirements.
[0139] Step 202: Non-AP STA 101 transmits the first radio frame on one of the links in the link.
[0140] In this embodiment of the disclosure, the non-AP STA transmits the first radio frame on any link established between it and the AP MLD.
[0141] In some embodiments, the first wireless frame includes at least one of the following:
[0142] The first identification information identifies whether the communication mode requested by the non-AP STA for the link is a first capability communication mode or a second capability communication mode;
[0143] The third identification information identifies the communication duration information requested by the link in the target communication mode for the non-AP STA.
[0144] In this second capability communication mode, at least one communication parameter is greater than the communication parameter in the first capability communication mode.
[0145] Specifically, the first identification information identifies the communication mode requested by the non-AP STA for the link. This communication mode can be one of two: a first capability communication mode or a second capability communication mode. If the communication mode is the second capability communication mode, then at least one communication parameter value will be greater than the corresponding communication parameter value in the first capability communication mode. The third identification information carries the communication duration requested by the non-AP STA for the link in the target communication mode. It enables the device to more accurately plan its own communication behavior, helping the device to more effectively manage energy consumption while meeting communication needs, and to flexibly switch communication modes according to actual conditions.
[0146] In some embodiments, the first identification information includes a link bitmap identifier, which is 2 bytes long and contains 16 bits. Each bit corresponds to a link. For example, a bit set to "0" indicates that the communication mode requested by the non-AP STA for the link is a low-capacity communication mode (hereinafter referred to as the first-capacity communication mode); a bit set to "1" indicates that the communication mode requested by the non-AP STA for the link is a high-capacity communication mode (hereinafter referred to as the second-capacity communication mode). Furthermore, both the high-capacity and low-capacity communication modes are in the awake state, and both modes can enter PS mode, i.e., the doze state.
[0147] The second capability communication mode can be adopted when the link requires more frequent data transmission or higher-speed communication, while the first capability communication mode can be an energy-saving strategy adopted in certain situations to reduce energy consumption. Thus, by parsing the Link bitmap identifier in the first identification information, the communication mode requested by the non-AP STA for each link can be understood, enabling efficient and rapid switching of communication modes for affiliated multi-connection site devices, further reducing equipment energy consumption.
[0148] In some embodiments, the first identification information may further include link status information identifiers, where each link may have different statuses to represent the requested communication mode. For example, "0" may be used to represent a first capability communication mode, and "1" to represent a second capability communication mode. These statuses are then associated with each link.
[0149] In some embodiments, the first wireless frame further includes at least one of the following:
[0150] The second identification information identifies the non-AP STA as having a first capability communication mode, a second capability communication mode, or a sleep state as requested by the link.
[0151] The third identification information identifies the non-AP STA as the communication duration information requested by the link in the target communication mode;
[0152] In this second capability communication mode, at least one communication parameter is greater than the communication parameter in the first capability communication mode.
[0153] Specifically, the second identification information can identify that the communication mode requested by the non-AP STA for the link is at least one of a first capability communication mode, a second capability communication mode, or a sleep state. The third identification information identifies the communication duration information requested by the non-AP STA for the link under the target communication mode.
[0154] For example, the second identification information may indicate that the non-AP STA requests a first-capability communication mode for the link, which may correspond to a default or lower communication setting. Alternatively, the second identification information may indicate that the non-AP STA requests a second-capability communication mode for the link, which may correspond to higher performance or more flexible communication parameter settings. Furthermore, the second identification information may indicate that the non-AP STA requests a sleep mode for the link, which may correspond to the device on the corresponding link temporarily not participating in communication to save energy or wait for a specific event to trigger. This versatility allows the non-AP STA to request different communication modes for different links according to actual needs, thereby better adapting to different application scenarios and environmental requirements.
[0155] In some embodiments, the second identification information includes a combination of the Link bitmap identifier and the PM identifier. The PM identifier information may include two bits: the first bit indicates whether the link corresponding to the Link bitmap identifier has entered a first capability communication mode or a second capability communication mode. For example, setting the first bit to "0" indicates that the link corresponding to the Link bitmap identifier has entered the first capability communication mode; setting the first bit to "1" indicates that the link corresponding to the Link bitmap identifier has entered the second capability communication mode. The second bit indicates whether the link corresponding to the Link bitmap identifier has entered a sleep state. For example, setting the second bit to "0" indicates that the link corresponding to the Link bitmap identifier has not entered a sleep state; setting the second bit to "1" indicates that the link corresponding to the Link bitmap identifier has entered a sleep state. In summary, the possible settings for the PM identifier information include the following cases one through four.
[0156] Case 1: The first bit of the PM identifier information is 0 and the second bit is 0: This indicates that the corresponding link identified by the Link bitmap has entered the first capability communication mode and has not entered the sleep state.
[0157] Scenario 2: The first bit of the PM identifier information is 0 and the second bit is 1: This indicates that the corresponding link identified by the Link bitmap has entered the first capability communication mode, but has entered a dormant state.
[0158] Case 3: The first bit of the PM identifier information is 1 and the second bit is 0: This indicates that the corresponding link identified by the Link bitmap has entered the second capability communication mode and has not entered the sleep state.
[0159] Case 4: The first bit of the PM identifier information is 1 and the second bit is 1: This indicates that the corresponding link identified by the Link bitmap has entered the second capability communication mode and entered a dormant state.
[0160] This embodiment combines the Link bitmap identifier and the PM identifier into a second identifier, enabling the AP MLD to directly read the communication mode and power management status of each link from the second identifier without additional parsing steps, thereby improving the system efficiency and performance.
[0161] In some embodiments, the second identification information may further include a combination of a link identifier field and a communication mode field. For example, a field is added to the header or a specific location of the first radio frame to represent a unique identifier for each link. This identifier can be a number, a letter, or other form of identifier. An array or list is added to the frame to store the communication mode corresponding to each link. The size of this array should match the number of links, with each element corresponding to a link and representing the communication mode of that link.
[0162] In some embodiments, the third identification information further includes the communication start time of the link under different capability communication modes. Specifically, when the first or second identification information identifies that the non-AP STA requests a first capability communication mode or a second capability communication mode for the link, the first radio frame includes the third identification information. The third identification information is carried in the duration field of the first radio frame. The third identification information is the communication duration information requested by the non-AP STA for the link under the target communication mode. This duration may include the start time, which can be the absolute value of the time under each link, or it can be calculated implicitly, i.e., the time when the request frame is received under the link plus the Time Synchronization Function (TSF) offset. Including the start time of the link entering the target communication mode as part of the third identification information allows the device to flexibly adjust the communication duration under different communication modes. At the same time, the TSF offset ensures time consistency, so that the communication time can be accurately recorded even when the device operates under different communication modes.
[0163] In some embodiments, a Frame Sequence Number (FSN) field can also be used to identify the communication duration information requested by the non-AP STA for the link in the target communication mode. For example, an FSN field can be included in the third identification information in the first radio frame, indicating the communication start time requested by the non-AP STA for the link in the target communication mode. The AP MLD can determine the communication start time requested by the non-AP STA for the corresponding link in the target communication mode based on this FSN field.
[0164] Step 203: AP 102, attached to AP MLD, receives the first radio frame sent by non-AP STA 101.
[0165] In this embodiment of the disclosure, an AP attached to an AP MLD receives a first radio frame on a link where a non-AP STA is sending the first radio frame. The first radio frame identifies a non-AP STA request to set one or more links with the AP MLD to a target communication mode; wherein the target communication mode is one of different capability communication modes. Based on this, the AP MLD can determine whether to accept the request from the first radio frame according to network requirements or the current link. For example, if a higher communication rate is currently required on a specific link, the AP MLD can accept the non-AP STA request, allowing the link to enter a second capability communication mode. Alternatively, if the current link is already heavily loaded, the AP MLD may reject the request to avoid overload and may suggest retrying at a later time. Such judgments and processing can be flexibly adjusted according to actual conditions to optimize network performance and stability.
[0166] Step 204, AP 102 attached to AP MLD determines a second radio frame; the second radio frame indicates whether AP MLD accepts the content requested by the first radio frame.
[0167] In this embodiment of the disclosure, after receiving a first radio frame, the AP attached to the AP MLD determines a second radio frame; the second radio frame indicates whether the AP MLD accepts the content requested by the first radio frame.
[0168] In some embodiments, the second wireless frame includes at least one of the following:
[0169] The first status code information indicates that the AP MLD has accepted the content requested by the first radio frame;
[0170] The second status code information indicates that the AP MLD rejects the content requested by the first radio frame;
[0171] The third status code information and the fourth identification field, wherein the third status code information indicates that the AP MLD rejects the content requested by the first radio frame, and the fourth identification field indicates the communication parameter information corresponding to each link suggested by the AP and / or the parameter value set by the third identification information;
[0172] The fifth identification field identifies the content requested by the first radio frame that the AP MLD rejects, and identifies the communication parameter information corresponding to each link suggested by the AP and / or the parameter value set by the third identification information.
[0173] Specifically, the second radio frame includes a status code field, a first status code indicating that the AP MLD accepts the content requested by the first radio frame (e.g., a status code field set to 1 indicates that the AP MLD accepts the content requested by the first radio frame), a second status code indicating that the AP MLD rejects the content requested by the first radio frame (e.g., a status code field set to 0 indicates that the AP MLD rejects the content requested by the first radio frame), a third status code, and a fourth identifier field. The third status code indicates that the AP MLD rejects the content requested by the first radio frame, and the fourth identifier field identifies the communication parameter information corresponding to each link suggested by the AP and / or the parameter values set by the third identifier information. For example, if the status code field is set to 0, the fourth identifier field will provide the communication parameter information corresponding to each link suggested by the AP and / or the parameter values set by the third identifier information. These communication parameter information may include one or more of BW, SS, MCS modes, and transmission rates to provide reference or adjustment for non-AP STAs. The fifth identification field identifies the content requested by the first radio frame that the AP MLD rejected, and identifies the communication parameter information corresponding to each link suggested by the AP and / or the parameter values set by the third identification information. For example, if the status code field is set to 0, the fifth identification field will provide the communication parameter information corresponding to each link suggested by the AP and / or the parameter values set by the third identification information. This communication parameter information may include one or more of BW, SS, MCS modes, and transmission rates, to provide non-AP STAs with reference or adjustment.
[0174] For example, when determining the second radio frame, the AP MLD checks the status of each link and the network load to determine whether to accept one or more links as the target communication mode. If the load on a link is light and the network service quality is not affected, the AP MLD may choose to set the status code to 1, indicating acceptance of entering the first capability communication mode on that link, thereby saving energy and optimizing network resource utilization; or if the load on a link is heavy, or there is real-time data transmission, the AP MLD may set the status code to 1, indicating acceptance of entering the second capability communication mode on that link. In this example, the status code values 0 and 1 are only examples and can be other values, which are not limited here. In this embodiment, through the status code field in the second radio frame, the non-AP STA can know whether the AP MLD has accepted its request, so it can adjust the communication strategy or parameters in a timely manner. In addition, the fourth identification information provides the AP with suggestions on communication parameters, which can help the non-AP STA optimize communication performance, adapt to the network environment, and save energy and resources.
[0175] Step 205: AP 102, attached to AP MLD, sends the second radio frame.
[0176] In this embodiment of the disclosure, the AP attached to the AP MLD sends a second wireless frame on the link where the first wireless frame is received. The second wireless frame indicates whether the AP MLD accepts the content requested by the first wireless frame, which can realize timely feedback and simplify the communication process.
[0177] Step 206: Non-AP STA 101 receives a second radio frame sent by AP 102, which is attached to AP MLD.
[0178] The second radio frame indicates whether the AP MLD accepts the content requested by the first radio frame.
[0179] In this embodiment of the disclosure, the non-AP STA receives the second radio frame on the link that sent the first radio frame. If the second radio frame indicates that the AP MLD accepts the content requested by the first radio frame, then one or more links with the multi-connection access point device AP MLD are set to a first capability communication mode or a second capability communication mode.
