[0086] Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.
[0087] As shown in Figure 1, the communication system 100 includes a first access point (AP) 101 and a second AP 102, a station (STA) 103 associated with the first AP, and a STA 104 associated with the second AP 102.
[0088] In some embodiments, the first AP101 and the second AP102 can be access points 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 the Ethernet. Specifically, an AP can be a terminal device or network device with a wireless fidelity 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.
[0089] In some embodiments, STA103 and STA104 include, 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.
[0090] Specifically, STA103 and STA104 can be terminal devices or network devices equipped with Wi-Fi chips. Optionally, site device 102 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.
[0091] 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.
[0092] 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.
[0093] 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.
[0094] 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 an Access Point (AP) device, while other sites in the BSS network that are not APs are called terminals, also known as non-AP STAs. APs 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.
[0095] Figure 2 is one of the interactive schematic diagrams of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, the method includes:
[0096] Step 201: The first AP determines the first wireless frame; wherein the first wireless frame includes first identification information, and the first identification information includes parameter information of the second AP; the parameter information includes: the operating frequency band information of the second AP after receiving the first wireless frame;
[0097] The first AP and the second AP do not operate simultaneously in the sub7GHz frequency band; the first AP and the second AP are attached to different AP MLDs.
[0098] In wireless communication technology, millimeter wave and sub-7GHz frequencies can complement each other through carrier aggregation or dynamic spectrum sharing. For example, millimeter waves can be used to offload traffic in densely populated urban areas to improve spectrum utilization and regional throughput. Millimeter waves typically refer to the 30GHz to 300GHz frequency band, while sub-7GHz includes lower frequency bands such as below 6GHz, which are used in 5G NR and Wi-Fi. The two differ significantly in coverage, bandwidth, and penetration. For instance, millimeter waves offer high bandwidth but limited coverage, making them suitable for densely populated areas; sub-7GHz offers wide coverage but lower bandwidth, making them suitable for broad coverage. In WLANs, these frequency bands may be utilized more efficiently to improve speed and capacity.
[0099] However, due to the significant differences between the 60GHz / 45GHz spectrum and the sub7GHz spectrum, the transmission distance under the 60GHz / 45GHz spectrum is much shorter than that under the sub7GHz spectrum. However, the higher bandwidth can significantly improve the system throughput. Therefore, the multi-band coordinated application of the 60GHz / 45GHz spectrum and the sub7GHz spectrum has certain application prospects.
[0100] In this embodiment of the disclosure, referring to Figure 1, the first AP 1 (AP1, attached to AP MLD1) and AP2 (attached to AP MLD2) are attached to different AP MLDs. The first AP transmits the parameter information of the second AP through a first radio frame. The parameter information includes the operating frequency band information after receiving the first radio frame. The first AP and the second AP do not operate simultaneously in the sub7GHz frequency band to avoid AP2 using the sub7GHz frequency band and forming an overlapping Basic Service Set (BSS, OBSS) with AP1, thereby causing OBSS interference. Specifically, with the rapid increase in wireless devices and applications, more and more wireless local area networks are being deployed in dense environments composed of multiple OBSSs, and wireless communication devices with different protocol standards often exist in the limited environment. The high-density deployment of WLANs inevitably leads to regional overlap of adjacent BSSs. To avoid interference, APs in adjacent BSSs need to operate on different frequency bands, but due to the limited available frequency band resources, this requirement is usually not met. When multiple unrelated BSSs operating in the same frequency band or with partially overlapping frequency bands are close enough to receive each other's transmission information, the AP or STA in the BSS that is transmitting information will block the AP or STA in other BSSs from transmitting information. This forms a co-channel interference problem in the OBSS network, which will seriously affect network performance and may even lead to network paralysis. Therefore, in this embodiment of the disclosure, the first AP and the second AP do not operate in the sub7GHz frequency band at the same time.
[0101] Optionally, while the first AP is communicating, for example, if the first AP is communicating using the sub7GHz frequency band, the second AP (or other APs attached to AP MLD2) can switch to another link (e.g., operating at the 60GHz frequency band) to communicate with its associated STA, so as to avoid the second AP forming an OBSS with the first AP when using the sub7GHz frequency band. Therefore, the first AP and the second AP do not operate in the sub7GHz frequency band at the same time.
[0102] Specifically, the first AP and the second AP do not operate in the sub7GHz band at the same time: for example, one of them operates in the sub7GHz band while the other operates in the 60GHz band or the 45GHz band; or both operate in the 60GHz band or the 45GHz band at the same time.
[0103] Step 102: The first AP transmits the first wireless frame in the sub7GHz band.
[0104] The first radio frame is, for example, a trigger frame. The first AP carries the parameter information of the second AP in the trigger frame. The parameter information includes the operating frequency band information after receiving the first radio frame, so that the second AP can communicate according to the operating frequency band information. If the first AP operates in the sub7GHz frequency band after sending the first radio frame, the second AP will not operate in that frequency band, so as to avoid the second AP forming an OBSS with the first AP when using the sub7GHz frequency band.
[0105] In some embodiments, the method includes:
[0106] The second wireless frame sent by the second AP in the sub7GHz band can be a beacon frame, or the third wireless frame sent by the associated STA of the second AP can be a Probe Request, to obtain the second AP's support capability information for the first operating frequency band and / or the sub7GHz band, wherein the first operating frequency band is not the sub7GHz band, such as the 45GHz band or the 60GHz band.
[0107] The support capability information includes: the link identification information and operating frequency band information of the working link of the second AP.
[0108] The first AP and the second AP can obtain mutually supported frequency band information through their respective associated STAs or through direct interaction between the two.
[0109] The second AP's support capability information for the first operating frequency band and / or sub7GHz frequency band, such as whether the second AP supports 60GHz communication or sub7GHz communication, can be broadcast by the second AP in a second sub7GHz radio frame. The first AP can then obtain the second AP's support capability information for the first operating frequency band and / or sub7GHz frequency band through the second radio frame. Alternatively, the first AP can obtain the information through a Probe Request frame sent by a STA associated with the second AP (e.g., STA104 in Figure 1). For example, the STA associated with the second AP carries the second AP's support capability information for the first operating frequency band and / or sub7GHz frequency band in the Probe Request frame it sends, and the first AP obtains the information through this Probe Request frame.
[0110] The support capability information includes: link identification information and operating frequency band information of the working links of the second AP (or its associated AP MLD); for example, link identification + frequency band identification information. Alternatively, the support capability information can also be the link identification information and operating frequency band information of the working links of the AP MLD associated with the second AP, for example, identifying which links of the AP MLD operate at 60GHz and which operate at sub7GHz, which can also be presented as link identification + frequency band identification information.
[0111] Figure 3 is a second interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 3, the above method includes:
[0112] Step 301: Within the current TXOP, the first AP determines the first radio frame; wherein, the first radio frame includes first identification information, and the first identification information includes parameter information of the second AP; the parameter information includes: the operating frequency band information of the second AP after receiving the first radio frame;
[0113] The first AP and the second AP do not operate simultaneously in the sub7GHz frequency band; the first AP and the second AP are attached to different AP MLDs.
[0114] In the current TXOP, while the first AP is communicating, for example, if the first AP is communicating using the sub7GHz frequency band, the second AP (or other APs attached to AP MLD2) can switch to another link (for example, the operating frequency band is 60GHz) to communicate with its associated STA, so as to avoid the second AP forming an OBSS with the first AP when using the sub7GHz frequency band. Therefore, the first AP and the second AP do not work in the sub7GHz frequency band at the same time.
[0115] In some embodiments, the first AP and the second AP operate simultaneously in the sub7GHz band, including at least one of the following cases 1 to 3:
[0116] Case 1: The first AP operates in the first operating frequency band, and the second AP operates in the sub7GHz frequency band; wherein, the first operating frequency band does not include the sub7GHz frequency band. For example, the first operating frequency band includes the 60GHz frequency band or the 45GHz frequency band, then the first AP operates in the 60GHz frequency band or the 45GHz frequency band, and the second AP operates in the sub7GHz frequency band.
[0117] Scenario 2: The first AP operates in the sub-7GHz band, and the second AP operates in the first operating frequency band; for example, if the first operating frequency band includes the 60GHz band or the 45GHz band, then the second AP operates in the 60GHz band or the 45GHz band, and the first AP operates in the sub-7GHz band.
[0118] Scenario 3: The first AP and the second AP operate in a first operating frequency band, and the first AP and the second AP do not form an OBSS within the first operating frequency band. For example, the first operating frequency band includes the 60GHz band or the 45GHz band, then the first AP and the second AP both operate in the 60GHz band or the 45GHz band, and do not form an OBSS between them.
[0119] In some embodiments, the parameter information of the second AP further includes at least one of the following:
[0120] The identification information of the second AP is used to identify the identity of the second AP;
[0121] The second AP's working duration information in the current TXOP, that is, the communication duration occupied within the current TXOP.
[0122] Step 302: Transmit the first radio frame in the sub7GHz band.
[0123] The first radio frame is, for example, a trigger frame. The first AP carries the parameter information of the second AP in the trigger frame, especially the operating frequency band information after receiving the first radio frame. Communication is based on the operating frequency band information. If the first AP operates in the sub7GHz frequency band after sending the first radio frame, the second AP does not operate in that frequency band, so as to avoid the second AP forming an OBSS with the first AP when using the sub7GHz frequency band.
[0124] Figure 4 is a third interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 4, the above method includes:
[0125] Step 401: Within the current Target Wake Time (TWT) Service Period (SP) or the current Restricted Target Wake Time (RTWT) SP, the first AP determines the first radio frame; wherein, the first radio frame includes first identification information, and the first identification information includes parameter information of the second AP; the parameter information includes: the operating frequency band information of the second AP after receiving the first radio frame;
[0126] The first AP and the second AP do not operate simultaneously in the sub7GHz frequency band; the first AP and the second AP are attached to different AP MLDs.
[0127] In a SP (TWT SP or RTWT SP), the first AP and the second AP can share their negotiated TWT SP and RTWT SP. For example, the negotiated SP can carry link identifier and frequency band information for mutual sharing.
[0128] Within the current TWT SP or the current RTWT SP, while the first AP is communicating, for example, if the first AP is communicating using the sub7GHz band, the second AP (or other APs attached to AP MLD2) can switch to another link (e.g., operating at a frequency of 60GHz) to communicate with its associated STA, so as to avoid the second AP forming an OBSS with the first AP when using the sub7GHz band. Therefore, the first AP and the second AP do not operate in the sub7GHz band at the same time.
[0129] In some embodiments, the first AP and the second AP operate simultaneously in the sub7GHz band, including at least one of the following cases 1 to 3:
[0130] Case 1: The first AP operates in the first operating frequency band, and the second AP operates in the sub7GHz frequency band; wherein, the first operating frequency band does not include the sub7GHz frequency band. For example, the first operating frequency band includes the 60GHz frequency band or the 45GHz frequency band, then the first AP operates in the 60GHz frequency band or the 45GHz frequency band, and the second AP operates in the sub7GHz frequency band.
[0131] Scenario 2: The first AP operates in the sub-7GHz band, and the second AP operates in the first operating frequency band; for example, if the first operating frequency band includes the 60GHz band or the 45GHz band, then the second AP operates in the 60GHz band or the 45GHz band, and the first AP operates in the sub-7GHz band.
[0132] Scenario 3: The first AP and the second AP operate in a first operating frequency band, and the first AP and the second AP do not form an OBSS within the first operating frequency band. For example, the first operating frequency band includes the 60GHz band or the 45GHz band, then the first AP and the second AP both operate in the 60GHz band or the 45GHz band, and do not form an OBSS between them.
[0133] In some embodiments, the parameter information of the second AP further includes at least one of the following:
[0134] The identification information of the second AP is used to identify the identity of the second AP;
[0135] The second AP's operating time information in the current TWT SP or the current RTWT SP, that is, the communication time occupied in the current TWT SP or the current RTWT SP.
[0136] Step 402: Transmit the first radio frame in the sub7GHz band.
[0137] The first radio frame is, for example, a trigger frame. The first AP carries the parameter information of the second AP in the trigger frame, especially the operating frequency band information after receiving the first radio frame. Communication is based on the operating frequency band information. If the first AP operates in the sub7GHz frequency band after sending the first radio frame, the second AP does not operate in that frequency band, so as to avoid the second AP forming an OBSS with the first AP when using the sub7GHz frequency band.
[0138] Figure 5 is a fourth interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 5, the above method includes:
[0139] Step 501: The first AP obtains the second AP's support capability information for the first operating frequency band and / or the sub7GHz frequency band through the second wireless frame sent by the second AP in the sub7GHz band, which can be a beacon frame or a third wireless frame sent by the associated STA of the second AP, which can be a Probe Request frame.
[0140] The support capability information includes: the link identification information and operating frequency band information of the working link of the second AP.
[0141] Step 502: Within the current TXOP or the current TWT SP, the first AP determines the first radio frame; wherein, the first radio frame includes first identification information, and the first identification information includes parameter information of the second AP; the parameter information includes: the operating frequency band information of the second AP after receiving the first radio frame;
[0142] The first AP and the second AP do not operate simultaneously in the sub7GHz frequency band; the first AP and the second AP are attached to different AP MLDs.
[0143] In some embodiments, the first AP and the second AP operate simultaneously in the sub7GHz band, including at least one of the following cases 1 to 3:
[0144] Case 1: The first AP operates in the first operating frequency band, and the second AP operates in the sub7GHz frequency band; wherein, the first operating frequency band does not include the sub7GHz frequency band. For example, the first operating frequency band includes the 60GHz frequency band or the 45GHz frequency band, then the first AP operates in the 60GHz frequency band or the 45GHz frequency band, and the second AP operates in the sub7GHz frequency band.
[0145] Scenario 2: The first AP operates in the sub-7GHz band, and the second AP operates in the first operating frequency band; for example, if the first operating frequency band includes the 60GHz band or the 45GHz band, then the second AP operates in the 60GHz band or the 45GHz band, and the first AP operates in the sub-7GHz band.
[0146] Scenario 3: The first AP and the second AP operate in a first operating frequency band, and the first AP and the second AP do not form an OBSS within the first operating frequency band. For example, the first operating frequency band includes the 60GHz band or the 45GHz band, then the first AP and the second AP both operate in the 60GHz band or the 45GHz band, and do not form an OBSS between them.
[0147] In some embodiments, the parameter information of the second AP further includes at least one of the following:
[0148] The identification information of the second AP is used to identify the identity of the second AP;
[0149] The second AP's working duration information within the current TXOP, current TWT SP, or current RTWT SP, i.e., the communication duration occupied within the current TWT SP or current RTWT SP.
[0150] Step 503: Transmit the first radio frame in the sub7GHz band.
[0151] The first radio frame is, for example, a trigger frame. The first AP carries the parameter information of the second AP in the trigger frame, especially the operating frequency band information after receiving the first radio frame. Communication is based on the operating frequency band information. If the first AP operates in the sub7GHz frequency band after sending the first radio frame, the second AP does not operate in that frequency band, so as to avoid the second AP forming an OBSS with the first AP when using the sub7GHz frequency band.
[0152] In this embodiment, the first AP carries first identification information in the first radio frame. This first identification information identifies the operating frequency band information of the second AP after receiving the first radio frame, ensuring that the first AP and the second AP do not operate simultaneously in the sub-7GHz band. This avoids the second AP forming an OBSS (Over-the-Side Array) with the first AP when using the sub-7GHz band. This embodiment provides a method for multi-band coordination between sub-7GHz and 60GHz or 45GHz bands to improve spectrum utilization and regional throughput.
