[0129] As shown in FIG1 , a communication system 100 includes a station device (STA) 101 and an access point device (AP) 102 .

[0130] 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.

[0131] Specifically, the station device 101 may be a terminal device or 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, and 802.11a, as well as the next generation 802.11 protocol, but is not limited thereto.

[0132] 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 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, as well as support the next generation 802.11 protocol, but is not limited to these.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] The various embodiments of the present disclosure can be applied to a wireless local area network (WLAN), such as a local area network that adopts 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 certain associations 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 with a dedicated BSS management function, which is called an access point device, and other stations in the BSS network that are not APs are called terminals, also called non-AP STAs. APs 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, etc., a STA cannot detect other STAs that are farther away from it, and the two are hidden nodes of each other.

[0137] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:

[0138] In step 201, the access point device 102 determines a first initial connection establishment frame; wherein, the first initial connection establishment frame includes first identification information, and the first identification information identifies that the AP (access point device 102) supports the UHR function, and the AP subsequently sends a first extended frame (Extended Frame) of the first initial connection establishment frame, and the first extended frame carries ultra-high reliability UHR related information.

[0139] The first initial connection establishment frame is used to establish an initial connection with a station device. The first initial connection establishment frame may be, for example, a beacon frame, a probe response frame, an association response frame, or a re-association response frame. The access point device 102 carries first identification information in the first initial connection establishment frame, identifying that the access point device 102 supports the UHR function through the first identification information. The first identification information also identifies that the AP subsequently sends a first extension frame of the first initial connection establishment frame, and the first extension frame carries ultra-high reliability (UHR) related information.

[0140] Optionally, the first initial connection establishment frame may carry capability information elements and / or operation information elements for each generation of standards (each generation of 802.11 protocols); capability information elements may include at least one of high throughput (HT) capabilities (28-octets, i.e., 28 octets), very high throughput (VHT) capabilities (14-octets), high efficiency (HE) capabilities (24-octets to 40-octets), and extremely high throughput (EHT) capabilities (greater than or equal to 19-octets); and operation information elements may include at least one of a multi-link (9-octet to 13-octets) information element and an EHT operation (8-octet to 13-octets) information element, to ensure the aforementioned compatibility of the access point device 102, so that station devices supporting HT, VHT, and HE can communicate with the access point device 102 and join the BSS of the access point device 102.

[0141] Access point device 102 uses first identification information to identify the AP and subsequently sends a first extended frame. The first extended frame carries ultra-high reliability (UHR) related information, such as a UHR capabilities information element, a UHR operation information element, broadcast period information of the first extended frame, service set identifier (SSID) information, timestamp information, and BSS change sequence information. By carrying ultra-high reliability (UHR) related information in the first extended frame to identify the UHR function supported by access point device 102, access point device 102 achieves backward compatibility, for example, allowing a station device supporting EHT to join the BSS of access point device 102. Since the first extended frame carries the access point device 102's support for the UHR function and the UHR related information supported by access point device 102, station device 101 obtains the aforementioned information when parsing the first extended frame, can quickly join the BSS of access point device 102, and perform UHR communication with access point device 102.

[0142] For the sake of backward compatibility, if the first identification information is sent through the first initial connection establishment frame or other initial access management frame, the frame length of the initial access management frame will inevitably become longer and longer, and the site device will need to consume more time and power to parse the initial access management frame, which is not conducive to power saving of the site device and the rapid joining of the site device to the BSS.

[0143] In some embodiments, the first initial connection establishment frame includes a beacon frame, and the UHR-related information includes at least one of the following:

[0144] UHR capabilities information element, UHR operation information element, broadcast period information of the first extended frame, SSID information, timestamp information and BSS change sequence information.

[0145] The access point device 102 periodically sends beacon frames at regular intervals, carrying UHR-related information in the beacon frames; these frames are used to synchronize the operation and sleep of devices in the network. For example, after receiving a beacon frame, the site device 101 joins the network and, based on the UHR capabilities information element and / or the UHR operation information element, determines the UHR capabilities information element that matches the UHR capabilities information element in the beacon frame and / or determines the UHR operation information element that matches the UHR operation information element in the beacon frame to determine the UHR-related capability information of the site device 101.

[0146] The broadcast period information of the first extended frame is used by the site device 101 to receive the first extended frame according to the broadcast period information.

[0147] Optionally, the UHR related information also includes at least one of SSID information, timestamp information and BSS change sequence information; the SSID information and timestamp information are used by the site device 101 to determine the BSS information of the access point device 102 and the BSS of the access point device 102; the BSS change sequence information is used to identify the BSS parameter changes of the access point device 102.

[0148] In some embodiments, the first initial connection establishment frame includes a probe response frame, an association response frame, or a re-association response frame;

[0149] The UHR-related information includes at least one of the following:

[0150] UHR capabilities information element, UHR operation information element.

[0151] When the station device 101 scans the 802.11 networks currently in the area, it sends a probe request frame to the access point device 102, and the access point device 102 replies with a probe response frame. When the station device 101 passes authentication and attempts to join the network, it sends an association request frame (or a re-association request frame) to the access point device 102, and the access point device 102 replies with an association response frame (or a re-association response frame).

[0152] The access point device 102 carries the UHR capabilities information element and / or the UHR operation information element in the probe response frame, the association response frame, and / or the re-association response frame to identify the UHR capability information supported by the access point device 102 .

[0153] In some embodiments, the first identification information is carried in the supported rates and BSS membership selectors information element of the first initial connection establishment frame, and the supported rates and BSS membership selectors are used to indicate that the access point device 102 supports the UHR function and carries UHR related information in the subsequent first extended frame.

[0154] In some embodiments, the first identification information includes:

[0155] The BSS membership selectors flag in the supported rates and BSS membership selectors information element;

[0156] Or a new flag bit added to the supported rates and BSS membership selectors information element.

[0157] Among them, the first identification information can use the BSS membership selectors identification bit, for example, assign a value to the BSS membership selectors identification bit, and use the value to indicate that the access point device 102 supports the UHR function and carries UHR related information in the subsequent first extended frame; or, add a new identification bit in the supported rates and BSS membership selectors information element to indicate that the access point device 102 supports the UHR function and carries UHR related information in the subsequent first extended frame.

[0158] In some embodiments, the value of the BSS membership selectors flag is set to a value different from that corresponding to high-throughput HT-related information, very high-throughput VHT-related information, high-efficiency HE-related information, or extremely high-throughput EHT-related information; wherein, for the case where the BSS membership selectors flag is used to indicate that the access point device 102 supports the UHR function and carries UHR-related information in a subsequent first extended frame, the value of the BSS membership selectors flag is set to a value different from that corresponding to the HT-related information, VHT-related information, HE-related information, or EHT-related information, so as to distinguish it from the HT-related information, VHT-related information, HE-related information, or EHT-related information.

[0159] Step 202: The access point device 102 sends the first initial connection establishment frame.

[0160] The access point device 102 carries first identification information in the first initial connection establishment frame, and the first identification information identifies that the access point device 102 supports the UHR function; and the first identification information also identifies that the AP subsequently sends a first extended frame of the first initial connection establishment frame, and the first extended frame carries ultra-high reliability UHR related information.

[0161] Step 203: The site device 101 receives a first initial connection establishment frame.

[0162] The site device 101 receives the first initial connection establishment frame, determines according to the first identification information that the access point device 102 supports the UHR function, and subsequently sends a first extended frame carrying UHR related information.

[0163] In step 204 , the access point device 102 sends a first extended frame, where the first extended frame carries ultra high reliability (UHR) related information.

[0164] The access point device 102 carries ultra high reliability (UHR) related information in the first extended frame, identifying related information of the UHR function supported by the access point device 102, so that the access point device 102 achieves backward compatibility.

[0165] Step 205: The site device 101 receives a first extended frame.

[0166] The first extended frame carries the information that the access point device 102 supports the UHR function and the UHR related information supported by the access point device 102. The site device 101 obtains the aforementioned information when parsing the first extended frame, and can quickly join the BSS of the access point device 102 and perform UHR communication with the access point device 102.

[0167] In step 206, the site device 101 determines a second initial connection establishment frame; wherein, the second initial connection establishment frame includes second identification information, and the second identification information indicates that: the STA supports the UHR function, and the STA subsequently sends a second extended frame of the second initial connection establishment frame, and the second extended frame carries UHR related information.

[0168] Site device 101 identifies, through second identification information, that it supports the UHR function and subsequently transmits a second extended frame. The second extended frame carries UHR-related information, such as the UHR capabilities information element and the UHR operation information element. By carrying UHR-related information in the second extended frame to identify the UHR function supported by site device 101, access point device 102 obtains the aforementioned information when parsing the second extended frame. If the information matches the UHR-related information of access point device 102, site device 101 can join the BSS of access point device 102 and conduct UHR communication with access point device 102.

[0169] For backward compatibility, if the second identification information is sent through a second initial connection establishment frame or other initial access management frame, the frame length of the initial access management frame will inevitably become longer and longer, and the access point device 102 will need to consume more time and power to parse the initial access management frame, which is not conducive to power saving of the access point device 102 and rapid joining of the site device 101 to the BSS.

[0170] In some embodiments, the second initial connection establishment frame includes a probe request frame, and the UHR-related information includes at least one of the following:

[0171] UHR capabilities information element, UHR operation information element.

[0172] When the site device 101 scans the 802.11 networks currently in the area, it sends a probe response frame to the access point device 102 . The probe response frame carries the UHR capabilities information element and / or the UHR operation information element to identify the UHR capability information supported by the site device 101 .

[0173] In some embodiments, the second initial connection establishment frame includes an association request frame or a re-association request frame;

[0174] The UHR-related information includes at least one of the following:

[0175] The UHR capabilities information element and UHR operation information element determined by the beacon frame.

[0176] The access point device 102 periodically sends beacon frames at certain time intervals. The beacon frames carry UHR related information, which are used to achieve synchronous operation and sleep of devices in the network.

[0177] After receiving the beacon frame, the site device 101 joins the network and determines, based on the UHR capabilities information element and / or the UHR operation information element, a UHR capabilities information element that is consistent with the UHR capabilities information element in the beacon frame, and / or determines a UHR operation information element that is consistent with the UHR operation information element in the beacon frame to determine the UHR-related capability information of the site device 101.

[0178] When the site device 101 passes authentication and attempts to join the network, it sends an association request frame (or a re-association request frame) to the access point device 102, and carries a UHR capabilities information element and / or a UHR operation information element in the association response frame and / or the re-association response frame to identify the UHR capability information supported by the access point device 102.

[0179] In some embodiments, the second identification information is carried in the supported rates and BSS membership selectors information element of the second initial connection establishment frame, and the supported rates and BSS membership selectors are used to indicate that the site device 101 supports the UHR function and carries UHR related information in a subsequent second extended frame.

[0180] In some embodiments, the second identification information includes:

[0181] The BSS membership selectors flag in the supported rates and BSS membership selectors information element;

[0182] Or a new flag bit added to the supported rates and BSS membership selectors information element.

[0183] Among them, the second identification information can use the BSS membership selectors identification bit, for example, assign a value to the BSS membership selectors identification bit, and use the value to indicate that the site device 101 supports the UHR function and carries UHR related information in the subsequent second extended frame; or, add a new identification bit in the supported rates and BSS membership selectors information element to indicate that the site device 101 supports the UHR function and carries UHR related information in the subsequent second extended frame.

[0184] In some embodiments, the value of the BSS membership selectors flag is set to a value different from that corresponding to high-throughput HT related information, very-high-throughput VHT related information, high-efficiency HE related information, or extremely-high-throughput EHT related information. Specifically, in the case where the BSS membership selectors flag is used to indicate that the site device 101 supports the UHR function and carries UHR related information in a subsequent first extended frame, the value of the BSS membership selectors flag is set to a value different from that corresponding to the HT related information, VHT related information, HE related information, or EHT related information, so as to distinguish it from the HT related information, VHT related information, HE related information, or EHT related information.

[0185] Step 207: The site device 101 sends the second initial connection establishment frame.

[0186] The site device 101 carries second identification information in the second initial connection establishment frame, and the second identification information identifies that the site device 101 supports the UHR function; and the second identification information also identifies that the site device 101 subsequently sends a second extended frame of the second initial connection establishment frame, and carries UHR related information in the second extended frame.

[0187] In step 208 , the access point device 102 receives a second initial connection establishment frame.

[0188] The access point device 102 receives the second initial connection establishment frame, determines according to the second identification information that the site device 101 supports the UHR function, and subsequently sends a second extended frame carrying UHR related information.

[0189] Step 209: The site device 101 sends the second extended frame.

[0190] The site device 101 carries UHR related information in the second extended frame, identifying related information of the UHR function supported by the site device 101, so that the access point device 102 achieves backward compatibility.

[0191] In step 210 , the access point device 102 receives a second extended frame.

[0192] The second extended frame carries the information that the site device 101 supports the UHR function and the UHR related information supported by the site device 101. The access point device 102 obtains the aforementioned information when parsing the second extended frame, so that the site device 101 can quickly join the BSS of the access point device 102 and perform UHR communication with the access point device 102.

[0193] In the disclosed embodiments, backward compatibility of access point devices is achieved by carrying UHR-related information in extended frames. Furthermore, the devices obtain UHR-related information when parsing the extended frames, enabling station device 101 to quickly join the BSS of access point device 102 and conduct UHR communication with access point device 102.
