[0097] In UHR, the communication methods related to the non-transmitted Basic Service Set Identifier (Non-transmitted BSSID) mechanism, such as the transmission of TWT SPs for Non-transmitted BSSID APs, require further research.
[0098] Figure 1 is one of the schematic diagrams of the architecture of a communication system according to an embodiment of the present disclosure.
[0099] As shown in Figure 1, the communication system 100 includes a first device 101 and at least one second device 102.
[0100] The first device can be an access point (AP), and the second device can be an AP or a site device (Non-Access Point Station, Non-AP STA).
[0101] In this system, the first device 101 can determine and send the first wireless frame, and each second device 102 can receive the first wireless frame.
[0102] The first wireless frame includes at least one second AP's Target Wake Time (TWT) Service Period (SP).
[0103] Among them, the first AP and the second AP belong to the same multiple BSSID set.
[0104] Among them, the second AP is the Non-transmitted Basic Service Set Identifier (BSSID) AP.
[0105] In the Non-transmitted BSSID mechanism, APs belonging to the Non-transmitted BSSID do not send management frames, and related messages can be broadcast through other APs belonging to the same multiple BSSID set.
[0106] In some embodiments, an AP 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 equipped 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.
[0107] In some embodiments, a Non-AP STA (hereinafter referred to as STA) includes, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports Wi-Fi 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 Wi-Fi communication, a car with Wi-Fi 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, and a wireless terminal device in a smart home.
[0108] Specifically, the STA can be a terminal device or network device with a Wi-Fi chip. Optionally, the site device 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.
[0109] Optionally, in this embodiment of the disclosure, AP and STA can be devices that support multiple links. 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 link communication functions, and Non-AP MLD can represent a site that supports multiple link communication functions.
[0110] 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.
[0111] 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.
[0112] 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 within a specific coverage area that have some kind of association. 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 an Access Point (AP), while other sites in the BSS network that are not APs are called terminals, also known as Non-AP STAs.
[0113] Figure 2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, the method includes:
[0114] S201, the first device sends a first radio frame, the first radio frame including at least one TWT SP of the second AP.
[0115] In this embodiment of the disclosure, the first device includes a first AP.
[0116] In this embodiment of the disclosure, the first AP and the second AP belong to the same Multiple Basic Service Set Identifier Set (BSSID Set).
[0117] The first AP can be called the reporting AP, and the second AP can be called the reported AP.
[0118] In this embodiment of the disclosure, the second AP is a Non-transmitted Basic Service Set Identifier (BSSID) AP, and the first AP can be a transmitted AP.
[0119] In WLAN, a Multiple BSSID set is a collection of cooperating Access Points (APs). All cooperating APs use the same operation set, channel number, or antenna interface. In the Multiple BSSID mechanism, a physical AP can virtualize multiple logical APs to form a Multiple BSSID set. Each virtualized AP manages one BSS. Different logical APs typically have different BSSIDs and permissions, such as security mechanisms or transmission opportunities. Within the Multiple BSSID set, usually only one AP's BSSID is configured as a Transmitted BSSID; the other APs' BSSIDs are configured as Non-Transmitted BSSIDs.
[0120] Generally, only APs with BSSIDs configured as Transmitted BSSIDs can send management frames; APs with other BSSIDs configured as Non-transmitted BSSIDs cannot. Management frames can be beacon frames or probe response frames. If a STA sends a probe request frame to an AP with a Non-transmitted BSSID in a Multiple BSSID set, the AP with the Transmitted BSSID needs to assist (or act on behalf of) the Non-transmitted BSSID AP in responding to the probe response frame, carrying information about the Non-transmitted AP, such as operating parameters (channel bandwidth, spatial flow, etc.).
[0121] Optionally, the information of the Multiple BSSID Set (i.e., the Multiple BSSID element) is carried in the beacon frame, probe response frame, or neighbor report frame sent by the Transmitted BSSID AP. Correspondingly, the BSSID information of the Non-transmitted BSSID AP is derived by receiving the aforementioned beacon frame, probe response frame, or neighbor report frame, based on the Multiple BSSID element, etc., within the beacon frame, probe response frame, or neighbor report frame.
[0122] In this embodiment of the disclosure, the first wireless frame may be a management frame, including but not limited to a beacon frame and an unsolicited probe response frame.
[0123] Optionally, the first wireless frame can be a broadcast frame.
[0124] In this embodiment of the disclosure, the first wireless frame further includes the TWT SP of the first AP.
[0125] As an example, the first wireless frame includes at least one TWT SP of the second AP.
[0126] As an example, the first wireless frame includes the TWT SP of the first AP and the TWT SP of at least one second AP.
[0127] In this embodiment of the disclosure, the first AP is in a power-saving state or an unavailable state outside of the first AP's TWT SP, and the second AP is also in a power-saving state or an unavailable state outside of the second AP's TWT SP.
[0128] For example, to prevent in-device interference (IDC), the first AP and / or the second AP are in a power-saving or unavailable state outside of their own TWT SPs to avoid IDC service interference.
[0129] In this embodiment of the disclosure, the first wireless frame includes at least one broadcast target wake-up time information.
[0130] Each broadcast target wake-up time information includes a TWT SP.
[0131] Optionally, the first radio frame includes a broadcast target wake-up time information element (BWT), which includes at least one broadcast target wake-up time information.
[0132] In other words, when the first radio frame includes the TWT SP of at least one second AP, the broadcast target wake-up time information element includes the broadcast target wake-up time information corresponding to each second AP, and the broadcast target wake-up time information corresponding to each second AP includes the TWT SP of the corresponding second AP.
[0133] Optionally, when the first radio frame includes the TWT SP of the first AP and the TWT SP of at least one second AP, the broadcast target wake-up time information element includes the broadcast target wake-up time information corresponding to the first AP and the broadcast target wake-up time information corresponding to each second AP. The broadcast target wake-up time information corresponding to the first AP includes the TWT SP of the first AP, and the broadcast target wake-up time information corresponding to each second AP includes the TWT SP of the corresponding second AP.
[0134] In this embodiment of the disclosure, when the first wireless frame includes multiple broadcast target wake-up time information, each broadcast target wake-up time information includes a first identifier bit.
[0135] Among them, the first identifier bit in the wake-up time information of each broadcast target has the first value, and the TWT SP included in the wake-up time information of the broadcast target is applicable to all STAs.
[0136] In other words, for any target broadcast wake-up time information corresponding to an AP, when the value of the first identifier bit is the first value, it indicates that when the STA needs to communicate with the AP, it needs to communicate with the AP within the TWT SP included in the target broadcast wake-up time information.
[0137] The first value can be 0 or other preset values, and there are no restrictions here.
[0138] Optionally, the first identifier can be a broadcast identifier (broadcast ID), for example, the Broadcast ID in the target wake-up time information of the TWT SP including the second AP (non-transmitted AP) can be set to 31.
[0139] In this embodiment of the disclosure, each broadcast target wake-up time information includes a second identifier bit, which identifies the AP to which the TWT SP included in the broadcast target wake-up time information belongs.
[0140] For each broadcast target wake-up time information, it can be identified by the identifier value of the second identifier bit, which specifically refers to the AP of the TWT SP.
[0141] As an example, when the value of the second flag bit in the wake-up time information of any broadcast target is the second value, the AP to which the TWT SP included in the flag belongs is the first AP, that is, the AP to which the TWT SP included in the flag belongs is the reporting AP; when the value of the second flag bit in the wake-up time information of any broadcast target is the third value, the AP to which the TWT SP included in the flag belongs is a second AP, that is, the TWT SP included in the flag belongs to a Non-transmitted BSSID AP or a reported AP.
[0142] As an example, the identifier value of the second identifier bit in each broadcast target wake-up time information can be different to identify the AP to which the included TWT SP belongs as a specific AP between the first AP and the second AP, that is, different APs in the first AP and the second AP correspond to different identifier values.
[0143] In this embodiment of the disclosure, the broadcast target wake-up time information corresponding to each second AP includes a multiple basic service set identifier element (BSSID Element), and the multiple basic service set identifier element includes the TWT SP of the corresponding second AP.
[0144] Optionally, the broadcast target wake-up time information corresponding to each second AP includes a multi-basic service set identification information element, and the multi-basic service set identification information element includes the TWT SP of the corresponding second AP.
[0145] Optionally, the broadcast target wake-up time information corresponding to each second AP includes a multi-basic service set identification information element, which includes an optional subelement field, and this information field includes the TWT SP of the corresponding second AP.
[0146] Optionally, the broadcast target wake-up time information corresponding to each second AP includes a multi-basic service set identification information element, which includes an optional subelement field, a non-transmitted profile field, and the TWT SP of the corresponding second AP.
[0147] As an example, the format of the multiple basic service set identification information element can be shown in Table 1:
[0148] Table 1:
[0149] The Optional Subelement information field can carry TWT SP.
[0150] The Optional Subelement information field may include the Non-transmitted Profile field, which includes the TWT SP.
[0151] S202, the first device completes data transmission before the end of the first TWT SP, or delays data transmission outside the first TWT SP by means of random backoff.
[0152] In this embodiment of the disclosure, after the first device sends the first wireless frame, the first device completes data transmission before the end of the first TWT SP, or delays data transmission outside the first TWT SP by means of random backoff.
[0153] Wherein, the first TWT SP is the TWT SP of the first device, and optionally, the first TWT SP is the TWT SP of the first AP.
[0154] Specifically, after obtaining a transmission opportunity (TXOP), if the first device needs to transmit data, it needs to complete the data transmission before the end of the first TWT SP of the first device.
[0155] Optionally, if the first device cannot complete the data transmission before the end of the first TWT SP after obtaining the transmission opportunity, the first device delays the data transmission by random backoff outside the first TWT SP.
[0156] It is important to note that for any second AP, after obtaining a transmission opportunity, if it needs to transmit data, it must complete the data transmission before its TWT SP. Alternatively, if the data transmission cannot be completed within its TWT SP, the second AP must delay the data transmission outside its TWT SP through a random backoff mechanism.
[0157] S203, when the second device needs to transmit data with the target AP in the first AP and the second AP, the data transmission is completed before the second TWT SP of the target AP ends, or the data transmission is delayed by random backoff outside the second TWT SP.
[0158] In this embodiment of the disclosure, after receiving the first wireless frame, when the second device needs to transmit data with the target AP in the first AP and the second AP, the second device completes the data transmission before the end of the second TWT SP of the target AP, or delays the data transmission by random backoff outside the second TWT SP.
[0159] The second device can be a STA associated with the first AP, a STA associated with any second AP, or another AP that receives the first broadcast wireless frame; there are no restrictions on this.
[0160] Specifically, after obtaining a transmission opportunity (TXOP), if the second device needs to transmit data with the target AP in the first AP and the second AP, the second device needs to complete the data transmission before the target AP's second TWT SP ends.
[0161] Optionally, if the second device cannot complete the data transmission before the end of the second TWT SP after obtaining the transmission opportunity, the second device delays the data transmission by random backoff outside the second TWT SP.
[0162] It should be noted that the QoS Short Retry Count of the corresponding data frames is not affected when the first and second devices delay data transmission through random backoff.

[0190] This disclosure provides a method for transmitting information related to a Non-transmitted BSSID AP. In this method, the reporting AP carries periodic power-saving / unavailable status information of the reporting AP in beacon frames, unsolicited probe response frames, or other management frames. It may also carry periodic power-saving / unavailable status information of one or more Non-transmitted BSSID APs.
[0191] Among them, the periodic power saving / unavailable status information can be TWT SP.
[0192] The reporting AP is included in the broadcast TWT information element and carries broadcast TWT information for both the reporting AP and each non-transmitted BSSID AP.
[0193] In the broadcast TWT information element (including reporting AP and non-transmitted BSSID AP), the broadcast ID is set to 0, indicating that the corresponding TWT SP applies to all STAs. It also carries an identifier bit indicating whether the TWT SP belongs to the reporting AP or the non-transmitted BSSID AP.

[0195] TWT SPs can be carried in the Non-transmitted profile field of the optional subelement information element.
[0196] After receiving the TWT SP, whether it is the AP or the STA acting as the TXOP holder in the TWT SP, if it needs to transmit data, it must ensure that the data can be transmitted before the TWT SP ends.
