[0126] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.
[0127] As shown in FIG1 , a communication system 100 includes a station device (STA) 101 and an access point device (AP) 102 .
[0128] In some embodiments, the 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 includes, but is not limited to, at least one of a mobile phone, a wearable device, an Internet of Things device that supports WiFi communication, a car with WiFi communication, 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 used in industrial control, a wireless terminal device used in self-driving, a wireless terminal device used in remote medical surgery, a wireless terminal device used in a smart grid, a wireless terminal device used in transportation safety, a wireless terminal device used in a smart city, and a wireless terminal device used in a smart home.
[0129] Specifically, the station device 101 may be a terminal device or network device equipped 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, and 802.11bn, as well as the next generation 802.11 protocol, but is not limited thereto.
[0130] In some embodiments, the access point device 102 can 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 various wireless network clients together and then connect the wireless network to the Ethernet. 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 and 802.11a, 802.11bf, 802.11bn, and support the next generation 802.11 protocol, but is not limited to this.
[0131] Optionally, in an embodiment of the present disclosure, the AP and STA may be devices supporting multiple connections, for example, they may be represented as a multi-connection access point device (AP MLD) and a multi-connection site device (Non-Access Point Multi-Link Device, Non-AP MLD), respectively; the AP MLD may represent an access point supporting multi-connection communication functions, and the non-AP MLD may represent a site supporting multi-connection communication functions.
[0132] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.
[0133] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.
[0134] The various embodiments of the present disclosure can be applied to wireless local area networks (WLANs), such as those using the 802.11 series of protocols. In a WLAN, a Basic Service Set (BSS) is a fundamental component of a WLAN. A BSS network consists of station devices with some association within a specific coverage area. One scenario 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 scenario is that in a BSS network, there is only one central station dedicated to managing the BSS, called an access point, and all 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 referred to as STAs. When describing STAs, there is no need to distinguish between APs and non-AP STAs. In the same BSS network, due to distance, transmission power, and other factors, a STA cannot detect other STAs that are farther away from it, and the two STAs are each other's hidden nodes.
[0135] FIG2 is one of the interactive diagrams of the power saving mode negotiation method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:
[0136] Step 201: The access point device determines a first radio frame; wherein the first radio frame includes first identification information, and the first identification information identifies SMPS mode information supported by the access point device.
[0137] In UHR, power saving (PS) is a research priority, but AP power saving is still under development. Typically, APs come in three forms: soft APs (or soft AP MLD), non-simultaneous transmitting and receiving (NSTR) mobile APs (or NSTR mobileAP MLD), and regular APs (or regular AP MLD). Regular APs, such as routers, support both simultaneous transmitting and receiving (STR) and NSTR communications. For example, soft APs and NSTR mobile APs are typically battery-powered, resulting in high power consumption. Furthermore, their communication with STAs is typically not continuous for extended periods. Therefore, a mechanism to support AP power saving is required.
[0138] In an embodiment of the present disclosure, the access point device 102 determines a first wireless frame, carries first identification information in the first wireless frame, and identifies, through the first identification information: the SM PS mode information supported by the access point device. Among them, the spatial multiplexing power save (SM PS) function, SM PS allows a device to retain only one active receive channel (receive chains) and use one antenna to receive signals; for example, when the STA receives the initial control frame sent by the AP, the other receive channels of the STA are turned on and multiple antennas are used to interact with the AP for frames. After the frame interaction is completed, the STA switches back to the single receive channel mode to achieve energy saving. Therefore, SM PS is a non-periodic power saving mode.
[0139] Step 202: The access point device 102 sends the first wireless frame.
[0140] The first radio frame may be a radio frame sent during an initial association process, such as a beacon frame, a probe response frame, an association response frame, or a reassociation response frame. The probe response frame may be an unsolicited probe response frame.
[0141] In this way, during the initial association process or other processes, the access point device 102 carries first identification information in the first radio frame, and identifies supported SM PS mode information through the first identification information. The supported SM PS mode information includes, for example, whether the access point device supports the SM PS mode, supported SM PS mode types, etc. It will be understood that the first identification information may be at the MLD level. For example, if the access point device 102 is attached to a certain AP MLD, the first identification information may identify SM PS mode information supported by one or more connected APs of the AP MLD.
[0142] The embodiments of the present disclosure provide a non-periodic power saving mechanism to achieve AP power saving and meet the requirements of UHR.
[0143] In some embodiments, the first identification information includes at least one of a first identification bit and a second identification bit:
[0144] Among them, the first identification bit identifies whether the access point device supports the SM PS mechanism; for example, the first identification bit occupies one bit, and the bit is set to 1, indicating that the access point device supports the SM PS mechanism; the bit is set to 0, indicating that the access point device does not support the SM PS mechanism.
[0145] The second identification bit identifies that the access point device supports static SM PS mode or dynamic SM PS mode; wherein, for example, in static SM PS mode, the access point device only supports receiving or sending one spatial stream at any time. For example, in dynamic SM PS mode, the access point device uses one SS to listen to the RTS frame sent by the STA, and uses multiple SSs to receive data frames sent by the STA, or uses multiple SSs to send data frames to the STA.
