[0002] In 802.11bn, the existing power saving technologies will be enhanced, and how the AP saves power will also be studied, with minimal impact on the STAs (including 802.11bn STAs and pre-11bn STAs) that have established associations with it.
[0003] In 802.11ah, the AP can save power outside the TWT SP. However, since 802.11ah is mainly applied to the spectrum below sub-1Ghz, backward compatibility issues do not need to be considered.

For example, when a pre-11bn STA performs an active scan, whether a response is required, etc. Also, in 802.11bn, devices may support multi-link communication. Summary of the Invention

[0105] Figure 1 It is a schematic diagram of the architecture of a communication system shown according to an embodiment of the present disclosure.
[0106] As Figure 1 shown, the communication system 100 includes a station device (Station, STA) 101 and an access point device (Access Point, AP) 102.
[0107] In some embodiments, the station device 101 includes, for example, a wireless communication chip supporting WiFi communication function, a wireless sensor, or a wireless communication terminal. Optionally, the wireless communication terminal is, for example, at least one of a mobile phone, a wearable device, an Internet of Things device supporting WiFi communication function, a car with WiFi communication function, a smart car, a tablet (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.
[0108] Specifically, the station device 101 may be a terminal device or a network device with a wireless fidelity (WiFi) chip. Optionally, the station device 101 may support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, 802.11bn, etc., and support the next-generation 802.11 protocol, but not limited thereto.
[0109] In some embodiments, the access point device 102 may be an access point for a mobile terminal to enter a wired network. The AP is equivalent to a bridge connecting a wired network and a wireless network. Its main function is to connect each wireless network client together and then connect the wireless network to the Ethernet. Specifically, the AP may be a terminal device or a network device with a wireless fidelity chip. Optionally, the AP may support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, 802.11bn, etc., and support the next-generation 802.11 protocol, but not limited thereto.
[0110] Optionally, in the embodiments of the present disclosure, the AP and the STA may be devices supporting multi-connection. For example, they may be respectively represented as a multi-connection access point device (Access Point Multi-Link Device, AP MLD) and a multi-connection station device (Non-Access Point Multi-Link Device, Non-AP MLD); the AP MLD may represent an access point supporting multi-connection communication functions, and the non-AP MLD may represent a station supporting multi-connection communication functions.
[0111] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly explaining 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. Those of ordinary skill in the art know that with the evolution of the system architecture and the emergence of new service scenarios, the technical solutions proposed in the embodiments of the present disclosure are equally applicable to similar technical problems.
[0112] The following embodiments of the present disclosure can be applied to Figure 1 the communication system 100 shown in the figure, or a part of the main body, but not limited thereto. Figure 1 The main bodies shown in the figure are examples. The communication system may include Figure 1 all or part of the main bodies in the figure, and may also include Figure 1 other main bodies outside the figure. The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between each main body is an example. Each main body may not be connected or may be connected, and its connection may be in any way, either directly connected or indirectly connected, either wired or wirelessly connected.
[0113] Embodiments of the present disclosure can be applied to a Wireless Local Area Network (WLAN), such as a local area network adopting the 802.11 series of protocols. In a WLAN, a Basic Service Set (BSS) is a basic component of a WLAN. A BSS network is composed of station devices with a certain association within a specific coverage area. One case of association is that stations communicate directly with each other in an ad-hoc network, which is called an Independent Basic Service Set (IBSS). Another more common case is that in a BSS network, there is only one central station dedicated to managing the BSS, which is called an access point device, and other STAs in the network are associated with it. Other stations in the BSS network that are not the central station are called terminals, also called non-AP STAs. Terminals and non-AP STAs are collectively called STAs. When describing STAs, there is no need to distinguish between APs and non-AP STAs. In the same BSS network, due to reasons such as distance and transmission power, one STA cannot detect other STAs that are far away from it, and the two are hidden nodes of each other.
[0114] Figure 2 It is an interaction schematic diagram of a communication method shown according to an embodiment of the present disclosure. As Figure 2 shown, the above method includes:
[0115] Step 201, the access point device 102 determines a second wireless frame; wherein, the second wireless frame includes the power saving (PS) state information of each working link of the access point device; the PS state information includes listening period information and sleep period information.
[0116] In UHR, power saving (PS) is the research focus, while for AP power saving, it is still in a state of being to be improved. Usually, an AP can include three forms, such as soft AP (or soft AP MLD), non-simultaneous transmitting and receiving (NSTR) mobile AP (or NSTR mobile AP MLD), and regular AP (or regular AP MLD). Among them, a regular AP, such as a router, supports simultaneous transmitting and receiving (STR) and NSTR communications. Taking soft AP and NSTR mobile AP as examples, they are usually battery-powered, with high power consumption, and their communication with the STA is usually not in a long-term continuous state. Therefore, a mechanism supporting AP power saving is needed.
[0117] In UHR, an AP may support multi-link communication, and an STA may also be attached to a non-AP MLD and support multi-link communication. According to the existing 802.11be architecture, multi-link communication is established between the two. Since on each link, the AP or AP MLD may enter the power-saving mode, and on each link, the AP will wake up at a certain time period for uplink and downlink transmissions. In UHR, the power-saving mechanism needs to be further improved to meet the transmission requirements of UHR.
[0118] In an embodiment of the present disclosure, the access point device 102 determines a second wireless frame; wherein, the second wireless frame includes power saving (PS) status information of each working link of the access point device; wherein, the PS status information identifies the power-saving state of the access point device, and the power-saving state can be a listening state or a sleep state. In the listening state, the device can listen for wireless frames sent by other devices but does not send wireless frames; in the sleep state, the device does not listen or send.
[0119] The PS status information includes listening period information and sleep period information, that is, the start time of the listening period and the start time of the sleep period of the access point device under each working link.
[0120] Step 202, the access point device 102 sends the second wireless frame.
[0121] Among them, the second wireless frame can be a beacon frame or other action frames. The access point device carries the PS status information of each working link in the second wireless frame, facilitating the station device to determine how to wake up the access point device according to the PS status information when there is uplink data to be transmitted.
[0122] Step 203, the station device 101 determines a first wireless frame; wherein, the first wireless frame includes target request information, and the target request information identifies that the station device requests to wake up the access point device under the target link to receive the data frame sent by the station device; the target request information includes multi-link information, and the multi-link information identifies the target link.
[0123] Among them, for the station device, or the STA attached to a certain Non-AP MLD, which receives the PS status information of the access point device carried in the second wireless frame, it can wake up the access point device through the first wireless frame. For example, if the station device has cached data frames to be transmitted, or there are burst or temporary low-latency services to be transmitted, it can send the first wireless frame during the listening period of the access point device to wake up the access point device through the first wireless frame.
[0124] Wherein, the first wireless frame includes target request information, and the target request information identifies that the station device requests to wake up the access point device under the target link to receive the data frame sent by the station device; the target request information includes multi-link information, and the multi-link information identifies the target link, and the target link includes one or more of the working links of the access point device.
[0125] It can be understood that the transmission identifier (Traffic Identifie, TID) of the data frame cached by the station device can be pre-mapped to the working link; the access point device supports multi-link communication, and the working link includes each link of the access point device (or the AP MLD to which the access point device belongs).
[0126] Optionally, the first wireless frame can be a Request to Send (RTS) frame or a Multi User-Request to Send (MU-RTS) frame.
[0127] The first wireless frame includes first identification information, and the first identification information identifies each target link; for example, in the case of 16 working links, the first identification information can occupy 2 bytes, and each bit is used to identify whether the corresponding working link is a target link; for example, if a certain bit is set to 1, it indicates that the AP under its corresponding link needs to wake up; if it is set to 0, it does not wake up.
[0128] Step 204, the station device 101 sends the first wireless frame to the access point device under the first link.
[0129] Among them, the first link is one of the working links of the access point device; when the station device is under the first link and within the listening period of the access point device, the station device sends a first wireless frame to the access point device (or the AP MLD to which the access point device belongs) to request the access point device to wake up under the target link and receive the data frame that the station device is about to send.
[0130] Step 205, the access point device 102 receives the first wireless frame sent by the station device under the first link.
[0131] Among them, the first wireless frame includes target request information, and the target request information identifies that the station device requests to wake up the access point device under the target link to receive the data frame sent by the station device; the target request information includes multi-link information, and the multi-link information identifies the target link.
[0132] In some embodiments, after receiving the first wireless frame sent by the station device, the method includes Step 206 or Step 208:
[0133] Step 206, wake up in advance under the target link and receive the trigger frame sent by the station device.
[0134] Step 208, wake up when the wake-up period of the target link arrives and receive the trigger frame sent by the station device.
[0135] Among them, in Step 206, the access point device can adopt an immediate response method to wake up in advance and receive the trigger frame sent by the station device when the power-saving state has not ended (for example, the sleep period has not ended, or the listening period has not ended).
[0136] It can also execute Step 208 and adopt a delayed response method to wake up when the wake-up period of the target link arrives and receive the trigger frame sent by the station device.
[0137] In some embodiments, the waking up in advance under the target link and receiving the trigger frame sent by the station device includes:
[0138] Under the first link, send an acknowledgment frame to the station device and wake up after time synchronization with the target link to receive the trigger frame sent by the station device.
[0139] Among them, when the access point device can adopt an immediate response method, when the power-saving state has not ended (for example, the sleep period has not ended, or the listening period has not ended), it wakes up in advance and, under the first link, sends an acknowledgment frame to the station device to notify the station device that the access point device wakes up in advance and is ready to receive the trigger frame sent by the station device.
[0140] In some embodiments, after waking up in advance under the target link and receiving a trigger frame sent by the station device, the method includes:
[0141] During the listening period of the working link of the access point device, if a probe request frame or a multi-connection probe request frame is received, wake up under the working link and respond to the probe request frame or the multi-connection probe request frame.
[0142] Among them, to ensure compatibility, the access point device still normally receives a probe request frame or a multi-connection probe request frame during the listening period of each of its working links; and wakes up under the link where the probe request frame or the multi-connection probe request frame is received, and responds to the probe request frame or the multi-connection probe request frame.
[0143] In some embodiments, the duration of the listening period and / or the sleep period of the access point device overlaps with the duration of the quiet element of the access point device.
[0144] Among them, during the duration of the quiet element of the access point device, no frame interaction occurs on the current channel, thereby ensuring that there is no interference from other STAs within the BSS when performing channel measurement. In the embodiments of the present disclosure, the duration of the listening period and / or the sleep period of the access point device overlaps, or partially overlaps, or completely overlaps with the duration of the quiet element of the access point device, so as to prevent other STAs from performing unnecessary wake-up during the listening period and / or the sleep period. For example, when other STAs have no buffered data to send during the listening period and / or the sleep period, the access point device is woken up. And when the STA has buffered data to send, the access point device can be woken up by the first wireless frame.
[0145] After step 206 or step 208, the method further includes:
[0146] Step 207, the station device 101 sends the buffered data frame to the access point device.
[0147] In the embodiments of the present disclosure, the access point device receives a first wireless frame sent by the station device under the first link; wherein, the first wireless frame includes target request information, and the target request information identifies that the station device requests to wake up the access point device under the target link to receive the data frame sent by the station device; after receiving the first wireless frame, the access point device can wake up in advance under the target link or wake up when the wake-up period arrives, receive the trigger frame sent by the station device, and receive the uplink data frame.
