[0087] Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0088] As shown in Figure 1, the communication system 100 includes a station (STA) 101 and an access point (AP) 102.

[0089] In some embodiments, site device 101 includes, 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.

[0090] Specifically, site device 101 can be a terminal device or network device with a Wi-Fi chip. Optionally, site device 101 can support multiple 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.

[0091] In some embodiments, access point device 102 can be an access point for mobile terminals to access a wired network. An 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 an Ethernet network. Specifically, an AP can be a terminal device or network device with a Wi-Fi chip. Optionally, the AP 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.

[0092] 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.

[0093] 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.

[0094] 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.

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.

[0095] 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.

[0096] Figure 2 is an interactive schematic diagram of a device power-saving method according to an embodiment of the present disclosure. As shown in Figure 2, the method includes:

[0097] Step 201, AP MLD determines a first radio frame; wherein, the first radio frame includes first identification information, the first identification information identifying that: at least one first affiliated AP of AP MLD has downlink low latency service being sent to its associated first affiliated non-AP STA;

[0098] The first affiliated AP and the first affiliated non-AP STA communicate via a first link. The first radio frame is used to wake up the first affiliated non-AP STA from a sleep state to a first capability state in order to receive downlink low-latency services from its associated AP.

[0099] The first associated non-AP STA is associated with the non-AP MLD; the non-AP MLD is associated with the AP MLD.

[0100] In wireless communication networks, a power-saving mechanism has been proposed to reduce the power consumption of communication equipment. The equipment can perform power management during communication to achieve power saving. Specifically, the power management modes mainly include Active Mode and Power Save Mode (PS Mode). Active Mode, or active state, is where the device does not enter power saving mode; all transceiver links operate normally, possessing transmission and reception capabilities, but consuming relatively high power. Power saving mode mainly includes Doze State and Awake State. In Doze State, the device shuts down its transceiver radio frequency links and does not perform any transmission or reception operations, resulting in extremely low power consumption. Devices operating in Doze State periodically wake up to check if their associated devices have cached data to send to them. In Awake State, the device enters Active State, possessing the transmission and reception capabilities of Active Mode, with power consumption the same as in Active Mode. Site equipment operating in power saving mode switches between Doze and Awake states, ensuring communication quality while reducing the duration of high power consumption, thus achieving power saving. For example, a site device indicates its power mode after completing the current frame exchange via the Power Management subfield of the Frame Control field in a radio frame. When the Power Management subfield is set to "0", it indicates that the site device is in active mode after completing the current frame exchange; when the Power Management subfield is set to "1", it indicates that the site device has entered power-saving mode after completing the current frame exchange. After entering sleep mode, the site device periodically wakes up and receives beacon frames to determine if its associated access point device has cached data to send to it. If the access point device has cached data to send, the site device switches to wake-up mode and sends a Power-Saving Poll (PS-Poll) frame or other radio frames to notify the access point device that it is in wake-up mode in preparation to receive cached data sent by the access point device.

[0101] Meanwhile, the continuous development of wireless communication technology has 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 and multi-connection site devices. While more links can provide more frequency resources and achieve higher throughput, when traffic load is low, multiple links or radio frequency (RF) links lead to wasted frequency resources and increased device power consumption. In particular, for multi-connection access point devices, keeping all auxiliary access point devices in an active state for extended periods increases energy consumption at the access point devices, which is detrimental to system energy efficiency optimization. Therefore, when access point devices and site devices use multi-link methods for data transmission, power-saving mechanisms need further enhancement.

[0102] In this embodiment of the disclosure, the AP MLD determines a first radio frame, which may be a beacon frame or a probe response frame. The first radio frame includes first identification information, which identifies that at least one first affiliated AP of the AP MLD has a downlink low-latency service being transmitted to its associated first affiliated non-AP STA. For example, when the AP MLD communicates with the non-AP MLD on a second link, the first identification information identifies that the AP MLD, operating on a first affiliated AP on another link, has a downlink low-latency service being transmitted to its associated first affiliated non-AP STA. The downlink low-latency service may be a temporary / burst low-latency service. The AP MLD determines the first radio frame and uses it to wake up the first affiliated non-AP STA from a dormant state to a first capability state to receive the downlink low-latency service from its associated AP (first affiliated AP).

[0103] The first capability state can be either the Awake State or a specific transmit / receive capability state. The Awake State has transmit / receive capabilities in active mode. The transmit / receive capability state is indicated by relevant operation parameters, such as operation bandwidth, number of spatial streams, modulation and coding scheme (MCS), etc.

[0104] In other words, when the first affiliated non-AP STA is in a dormant state, if its associated first affiliated AP has temporary / burst low-latency services that need to be sent to the first affiliated non-AP STA, the AP MLD sends a first radio frame on the second link to wake up the first affiliated non-AP STA across the link. After the non-AP MLD receives the first radio frame on the second link, the first affiliated non-AP STA switches from a dormant state to a first capability state to receive downlink low-latency services from its associated first affiliated AP. Compared to periodically waking up after entering power-saving mode to check if its associated AP has buffered downlink data to send, the wake-up method of this embodiment is more conducive to energy saving of the non-AP MLD and can better guarantee the timeliness of low-latency service transmission.

[0105] In some embodiments, the first identification information includes at least one of the following:

[0106] The first identification field identifies at least one first affiliated AP of the AP MLD, which has downlink low-latency services transmitted to its associated first affiliated non-AP STA; wherein each of the first identification fields indicates each first affiliated non-AP STA, for example, the first identification field may be a Link ID, identifying the affiliated non-AP STA where the Link is located.

[0107] Each of the first identifier fields corresponds to a second identifier field; the second identifier field indicates the operating parameter information of the non-AP STA identified by the first identifier field when switching from a dormant state to the first capability state. Each second identifier field corresponds one-to-one with the first identifier field. Each second identifier field indicates the affiliated non-AP STA identified by the first identifier field when switching from a dormant state to the first capability state. For example, each second identifier field is an RX MCS And NSS Set field, indicating that the corresponding first affiliated non-AP STA switches to the first capability state, and after switching to the first capability state, selects appropriate MCS and NSS to complete low-latency service switching with its associated AP.

[0108] As a first example, referring to Figure 3A, the first identification information includes a first identification field (Link ID) and a second identification field (RX MCS And NSS Set field) corresponding to each first identification field.

[0109] In some embodiments, the first identification information includes:

[0110] The first identification field identifies at least one first affiliated AP of the AP MLD, indicating that a downlink low-latency service is being sent to its associated first affiliated non-AP STA; wherein each first identification field indicates each first affiliated non-AP STA. For example, the first identification field may be a link bitmap field, which contains one or two bytes in length, with each bit corresponding to a link. When a bit is set to a first parameter value (e.g., 1), it indicates that the affiliated AP of the corresponding link is sending a downlink low-latency service to its associated affiliated non-AP STA; after receiving the information, the affiliated non-AP STA with the bit set to the first parameter switches from a dormant state to a first capability state.

[0111] As a second example, referring to Figure 3B, the first identification information, as shown in Figure 3B, includes a first identification field (LinkBitmap). The first identification field, for example, is the Target Wake Up Link Bitmap in Figure 3B, which can be carried in the A-Control field of the first radio frame; for example, it can be carried in the WK Control field in the HE variant HT Control field. The HE variant HT Control field also includes the OM Control field and the padding field.

[0112] Step 202: Send the first radio frame to the non-AP MLD via the second link; the second link is the enabled link between the AP MLD and the non-AP MLD.

[0113] Specifically, the AP MLD sends the first radio frame to the non-AP MLD via the second link. The second auxiliary AP of the AP MLD and the second auxiliary non-AP STA of the non-AP MLD operate on the second link, with the second auxiliary non-AP STA in Active Mode or Awake State, and the first auxiliary non-AP STA in Doze State.

[0114] Step 203: The non-AP MLD receives the first radio frame under the second link, controls the first affiliated non-AP STA identified by the first identification field to switch from the sleep state to the first capability state, and the first affiliated non-AP STA participates in channel contention after switching to the first capability state; an acknowledgment message frame is sent to the AP MLD through the second link; other affiliated non-AP STAs maintain their current working state or working mode.

[0115] Step 204: The AP MLD receives an acknowledgment message frame sent by the first associated non-AP STA.

[0116] After step 204, you can execute either step 205 or step 206.

[0117] Step 205 includes steps 2051 and 2052.

[0118] In step 2051, the AP MLD accesses the first link and sends a control frame initial frame exchange to the first affiliated non-AP STA. The control frame is used to initialize the frame exchange process. The control frame can be a Request To Send (RTS) frame or a Multi User-Request To Send (MU-RTS) trigger frame.

[0119] After step 205, step 2052 is executed, whereby the non-AP MLD accesses the first link and receives the control frame initial frame exchange sent by the AP MLD.

[0120] The non-AP MLD sends a second radio frame to the first auxiliary AP. The second radio frame is used in response to the control frame. For example, the second radio frame is a clear to send (CTS) frame to acknowledge receipt of the control frame.

[0121] After step 205, proceed to steps 207 through 209.

[0122] Step 206: The non-AP MLD sends a third radio frame to the first auxiliary AP. The third radio frame indicates that the first auxiliary non-AP STA requests the first auxiliary AP to send downlink low-latency services. The third radio frame includes a power-saving mode polling (PS-Poll) frame or a trigger frame.

[0123] After step 206, proceed to steps 207 through 209.

[0124] Step 207: Upon receiving the second or third radio frame, the first affiliated AP sends a downlink low-latency service to its associated first affiliated non-AP STA.

[0125] The first auxiliary AP that does not receive the second or third wireless frame shall maintain its current operating state or operating mode.

[0126] Step 208: The first affiliated non-AP STA identified by the first identification field receives downlink low-latency services sent by the first affiliated AP; other affiliated non-AP STAs maintain their current working state or working mode.

[0127] Step 209: After receiving the downlink low-latency service, the first auxiliary non-AP STA enters sleep mode.

[0128] In this embodiment, if a non-AP MLD's associated non-AP STA is in a dormant state, and its associated AP, which is also associated with the AP MLD, experiences temporary / burst low-latency service transmission, the AP MLD can inform the non-AP MLD of the existence of the low-latency service during frame exchange with the non-AP MLD on other links (second links), thus achieving cross-link wake-up of the non-AP MLD's associated non-AP STA. Furthermore, upon receiving the first radio frame, the corresponding non-AP STA associated with the non-AP MLD switches from a dormant state to the corresponding capability state to promptly receive the low-latency service sent by its associated AP. On one hand, this embodiment can achieve cross-link dormant-to-wake-up indication between multi-link devices, improving the power-saving state switching speed; on the other hand, this embodiment helps reduce the transmission latency of low-latency services, further improving transmission efficiency.
