[0045] second capability information, identifying whether the first device supports sequential listening and / or simultaneous listening;

[0046] The third capability information identifies the channel identifier of the first channel supported by the first device for switching.

[0047] In the above embodiment, by providing one or more of the first capability information, second capability information and third capability information of the first device supporting switching to secondary channel communication in the first wireless frame, the device can select the most suitable channel as needed to improve communication quality and stability.

[0053] In the above embodiment, by carrying capability information in specific information elements in the first radio frame, information transmission overhead during communication can be reduced, and device capability information is transmitted only when needed, thereby improving communication efficiency. Furthermore, integrating capability information into specific information elements or fields helps support future expansion. If new or modified capability information is needed, it can be implemented by expanding these elements or fields without requiring large-scale changes to the entire communication protocol.

[0074] In the above embodiment, when the activation duration of a secondary channel expires or activation needs to be terminated early, the first device can proactively send a secondary channel listening activation termination frame to notify other devices to release the channel. This helps to release resources in a timely manner, avoid unnecessary channel occupation, and improve effective resource utilization.

[0115] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0116] As shown in Figure 1, communication system 100 includes a first device 101 and a second device 102. The first device can be a station (STA) or an access point (AP); the second device can be a STA or an AP. For example, when first device 101 is a STA, second device 102 is an AP; when first device 101 is an AP, second device 102 is a STA.

[0117] In some embodiments, the first device 101 and the second device 102 include, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports WiFi communication functions. Optionally, the wireless communication terminal is, for example, a mobile phone, a wearable device, an Internet of Things device that supports WiFi communication functions, a car with WiFi communication functions, a smart car, a tablet computer, a computer with wireless transceiver functions, 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, or a wireless terminal device in a smart home, but is not limited thereto.

[0118] Specifically, the first device 101 and the second device 102 may be terminal devices or network devices with wireless fidelity (WiFi) chips. Optionally, the first 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 support the next generation 802.11 protocol, but is not limited thereto.

[0119] In some embodiments, the first device 101 and the second device 102 can be access points for mobile terminals 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.

[0120] 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.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:

[0125] Step 201: The first device 101 determines a first radio frame; wherein the first radio frame includes capability information of the first device 101 supporting switching to a secondary channel for communication.

[0126] In WLAN, channels are usually divided into primary channels and secondary channels (or non-primary channels, also called auxiliary channels, non-primary channels); among them, secondary channels can contain one or more sub-channels. For example, if the division is based on 20MHz as the basic bandwidth unit, when the channel bandwidth is 20MHz, there is only one primary channel with a bandwidth of 20MHz; when the channel bandwidth is greater than 20MHz, a channel with a bandwidth of 20MHz is the primary channel, and the remaining one or more 20MHz channels are secondary channels. The primary 20MHz channel is the common channel of operation for stations that are members of the basic service set (BSS). Stations in the BSS can compete for channels on the primary 20MHz channel to seize channel resources.

[0127] As an example, as shown in FIG4 , the primary channel is, for example, the primary 20 MHz channel in FIG4 ; wherein the secondary channel may include one or more sub-channels, for example, the 20 MHz secondary channel and the 40 MHz secondary channel in FIG4 .

[0128] During the channel contention process, if the primary channel is in the OBSS busy state (OBSS interference), as shown in the T1 and T2 time periods in the figure, for example, it is occupied by other devices in the same OBSS as the WLAN, and other devices send physical layer protocol data units (PPDUs) on the primary channel, then the primary channel is in the OBSS busy state. If the primary channel is in the OBSS busy state, in order to fully utilize the channel resources, it can be switched to a secondary channel for communication to improve the communication system throughput and maximize channel resource utilization. For example, in the T1 time period, it can switch to a 20MHz secondary channel for communication, or in the T2 time period, it can switch to a 40MHz secondary channel for communication.

[0129] If the primary channel is in an idle state, as shown in the T3 time period in the figure, the AP and STA can send PPDUs to each other.

[0130] In addition, when communication is carried out on the primary channel (the secondary channel is busy), when the secondary channel is idle, the primary and secondary channels can be aggregated for communication to improve the system throughput; as an example, as shown in Figure 5, during the transmission of each frame, the primary channel and at least one secondary channel can be aggregated for transmission.

[0131] In some embodiments, the first wireless frame includes but is not limited to a Beacon frame, a Probe Response frame, an Association Response frame, and a Reassociation Response frame in the process of establishing an initial association between the first device and the second device.

[0132] In this way, during the initial association process between the first device and the second device, the capability information of the first device supporting switching to the secondary channel communication is determined, and the capability information is sent to the second device to facilitate subsequent channel switching based on the capability information.

[0133] Step 202 : The first device 101 sends the first radio frame to the second device 102 .

[0134] In some embodiments, the first device sends a first radio frame during the initial association process with the second device, and the first radio frame identifies the capability information of the first device supporting switching to the secondary channel for communication when the primary channel senses busy.

[0135] In some embodiments, the second device may also send a second radio frame during the process of establishing an initial association with the second device, wherein the second radio frame includes capability information of the second device supporting switching to the secondary channel for communication.

[0136] Step 203: The second device 102 receives a first radio frame sent by the first device 101; wherein the first radio frame includes capability information of the first device 101 supporting switching to secondary channel communication.

[0137] The second device receives a first radio frame sent by the first device during the process of establishing an initial association with the first device, and obtains information about the first device's capability to support switching to secondary channel communication by parsing the first radio frame. Alternatively, the first device receives a second radio frame sent by the second device during the process of establishing an initial association with the second device, and obtains information about the second device's capability to support switching to secondary channel communication by parsing the second radio frame.

[0138] In this way, in UHR, the disclosed embodiments improve system throughput and reduce communication latency. When a device detects a busy primary channel, it deems the primary channel congested or experiencing interference, triggering a channel switch decision. For example, the device switches to a secondary channel and, based on the device's capability information indicating that it supports switching to the secondary channel, monitors data transmission activity on the secondary channel to ensure that there is no other device activity on the secondary channel or that the detected other device activity is insufficient to interfere with communication. If the device detects an appropriate idle or low-interference state on the secondary channel, it can begin data exchange with the second device on the secondary channel and perform required operations, including data transmission and control frame transmission. This avoids the continuous monitoring of the secondary channel, which would cause the device to consume power, thereby increasing energy consumption, and prevents the device from receiving a large amount of invalid data on the secondary channel, which would waste processing power and network resources. The disclosed embodiments improve the primary and secondary channel communication mechanisms, enabling the device to switch to the secondary channel for communication when the primary channel is busy. This improves system throughput, reduces latency, and saves power, thus meeting UHR requirements.

[0139] In some embodiments, the capability information of the first device supporting switching to the secondary channel for communication includes at least one of first capability information, second capability information, and third capability information:

[0140] First capability information, identifying whether the first device supports switching to secondary channel communication. For example, the first capability information is carried in an extended capability information element of the first radio frame. For example, the first identification field of the extended capability information element is used to identify whether the first device supports switching to secondary channel communication. When the parameter value of the first identification field is set to 1, it indicates that the first device supports switching to secondary channel communication; when the parameter value of the first identification field is set to 0, it indicates that the first device does not support switching to secondary channel communication.

[0141] Second capability information identifying whether the first device supports sequential listening and / or simultaneous listening. For example, the second capability information is carried in an extended capability information element of the first radio frame. For example, the second identification field of the extended capability information element identifies whether the first device supports sequential listening and / or simultaneous listening. The parameter value setting of the second identification field is not specifically limited.

[0142] Typically, before sending data, each station device on the network must listen to see if there is other data being transmitted on the channel, for example, through a carrier sense mechanism. When the AP is about to switch to the secondary channel for communication, it will notify the STA, for example, by sending a request to send (RTS) frame or a buffer status report poll (BSRP) control frame to the STA. When the AP sends the RTS frame or BSRP control frame, the STA needs to listen on the secondary channel to receive the RTS frame or BSRP control frame; therefore, to switch to the secondary channel for communication when the primary channel is busy, the access point device 102 needs to support the station device 101 to listen to the secondary channel.

[0143] Optionally, when there are at least two secondary channels, the secondary channels are sensed sequentially or simultaneously. Sequential sensing means sensing is performed in different time periods on each secondary channel, while simultaneous sensing means sensing is performed simultaneously on multiple secondary channels, and the random backoff numbers generated in each secondary channel are independent of each other.

[0144] The third capability information identifies the channel identifier of the first channel supported by the first device for switching. For example, the third capability information is carried in the secondary information field of the ultra-high reliability operation UHR operation element information element of the first radio frame.

[0145] As an example, the UHR operation element information element portion of the first radio frame is shown in Table 1 below: it includes an information element identifier Element ID field, an information element length Length field, an information element extension Element extension field, an ultra-high reliability operation parameter UHR operation parameters field, and an information element secondary infos field. Among them, the secondary infos field can carry information about multiple secondary channels supported by the first device, including information based on the primary channel as a reference point and a channel identifier of the primary channel.

[0146] Table 1:

[0147] In some embodiments, the third capability information may also be carried in a secondary channel offset information element of the first radio frame. The secondary channel offset of the secondary channel offset information element is set to a first parameter value, indicating that there are multiple first channels. For example, when the parameter value of the secondary channel offset is set to 4, it indicates that there are 4 first channels; when the parameter value of the secondary channel offset is set to 8, it indicates that there are 8 first channels. The multiple first channels may have the same center frequency as the main channel, or the center frequencies of the multiple first channels may be below the main channel, and no specific limitation is made here.

[0148] In some embodiments, the secondary channel information may also be carried in an extended element of the secondary channel offset information element of the first radio frame.

[0149] As an example, the extended element part of the secondary channel offset information element of the first radio frame is as shown in the following Table 2: which includes: secondary channel number information secondary channel number and secondary channel existence identifier Secondary channel bitmap.

[0150] Table 2:

[0151] In some embodiments, the bandwidth of the secondary channel may be based on any one of 20 MHz, 40 MHz, 60 MHz, and 80 MHz, and is not specifically limited here.

[0152] As an example, referring to FIG3 , FIG3 shows an optional implementation of the embodiment of the present disclosure, including the following steps:

[0153] In step 301, the first device 101 determines a first secondary channel listening activation request frame, wherein the first secondary channel listening activation request frame is used to request activation of a secondary channel, and the secondary channel is one or more of the first channels.

[0154] In some embodiments, after a first device and a second device complete an exchange of information regarding their capabilities for switching to secondary channel communication during an initial association process, the first device or the second device determines to send a secondary channel listening activation request frame. The secondary channel listening activation request frame may carry the same secondary channel information as the radio frame used in the initial association process.

[0155] In some embodiments, the secondary channel listening activation request frame further includes identification information and / or activation duration information of the secondary channel. For example, if the first device or the second device supports sequential listening, the secondary channel listening activation request frame further includes identification information and / or activation duration information of the secondary channel.

[0156] Step 302 : The first device 101 sends the first secondary channel listening activation request frame to the second device 102 .

[0157] In some embodiments, the first device sends a first secondary channel listening activation request frame to the second device, where the first secondary channel listening activation request frame is used to request activation of a secondary channel.

[0158] In some embodiments, the second device sends a second secondary channel listening activation request frame to the first device, where the second secondary channel listening activation request frame is used to request activation of the secondary channel.

[0159] In step 303 , the second device 101 receives a first secondary channel listening activation request frame sent by the first device 101 ; the first secondary channel listening activation request frame is used to request activation of a secondary channel.

[0160] In some embodiments, the second device receives a first secondary channel listening activation request frame sent by the first device, and obtains the secondary channel requested to be activated by the first device and the secondary channel information by parsing the first secondary channel listening activation request frame.

[0161] In some embodiments, the first device receives a second secondary channel listening activation request frame sent by the second device, and obtains the second channel requested to be activated by the second device and the second channel information by parsing the second secondary channel listening activation request frame.

[0162] In step 304 , the second device 102 sends a first secondary channel listening activation response frame to the first device 101 .

[0163] In some embodiments, when the first device sends a first secondary channel listening activation request frame to the second device, the second device sends a first secondary channel listening activation response frame to the first device. When the second device sends a second secondary channel listening activation request frame to the first device, the first device sends a second secondary channel listening activation response frame to the second device.

[0164] Step 305: The first device 101 receives a first secondary channel listening activation response frame sent by the second device.

[0165] The first secondary channel listening activation response frame carries a first status code, and when the status code is set to a second parameter value, it indicates that the second device accepts the activation establishment. For example, when the status code is set to 0, it indicates that the second device activates the second channel establishment.

[0166] When the status code is set to the third parameter value, it indicates that the second device refuses to activate the establishment. For example, when the status code is set to 2, it indicates that the second device refuses to activate the second channel establishment.

[0167] When the status code is set to the fourth parameter value, it indicates that the second device refuses activation establishment, and the first secondary channel listening activation response frame includes the secondary channel information suggested by the second device, where the secondary channel information includes a channel identifier and activation duration information. For example, when the status code is set to 3, it indicates that the second device refuses activation establishment, but the first secondary channel listening activation response frame may carry the secondary channel information suggested by the second device, where the secondary channel information includes a suggested secondary channel identifier and suggested secondary channel activation duration information.

[0168] In some embodiments, the activation duration starts counting after the first device receives the first secondary channel listening activation response frame sent by the second device, or starts counting after a preset time threshold after the first device receives the first secondary channel listening activation response frame sent by the second device.

[0169] In some embodiments, terminating the listening activation of the secondary channel can be achieved by the first device sending a secondary channel listening activation termination frame, or by the first device receiving a secondary channel listening activation termination frame, or after the activation time of the secondary channel expires.

[0170] It can be seen that the embodiment of the present disclosure defines a listening activation mechanism for the device to switch to the secondary channel, so that when the device is busy in the main channel, it can switch to the secondary channel for perception communication, improve system throughput and reduce latency, so as to save power for the device and thus meet UHR requirements.

[0171] In an embodiment of the present disclosure, a first device determines a first radio frame; the first radio frame includes information indicating the first device's ability to switch to a secondary channel for communication; and transmits the first radio frame to a second device. Providing the information indicating the first device's ability to switch to a secondary channel in the first radio frame facilitates switching to the secondary channel for communication when the primary channel detects busyness, thereby improving system throughput and reducing latency, thereby saving power for the device and meeting UHR requirements.
