[0130] In some embodiments, the access point device 102 can be an access point for a mobile terminal to enter a wired network. The AP is equivalent to a bridge connecting a wired network and a wireless network. Its main function is to connect various wireless network clients together and then connect the wireless network to the Ethernet. Specifically, the AP can be a terminal device or a network device with a wireless fidelity chip. Optionally, the AP can support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11bn, 802.11bf and 802.11a, as well as support the next generation 802.11 protocol, but is not limited to this.

[0131] Optionally, in an embodiment of the present disclosure, the AP and STA may be devices supporting multiple connections, for example, they may be represented as a multi-connection access point device (Access Point Multi-Link Device, AP MLD) and a multi-connection site device (Non-Access Point Multi-Link Device, Non-AP MLD), respectively; AP MLD may represent an access point that supports multi-connection communication functions, and non-AP MLD may represent a site that supports multi-connection communication functions.

[0132] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0133] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0134] The various embodiments of the present disclosure can be applied to 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.

[0135] FIG2 is one of the interactive diagrams of the perception mode negotiation method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:

[0136] In step 201, the site device 101 determines a first wireless frame; wherein the first wireless frame includes first identification information; the first identification information identifies a perception mode in which the site device listens on an auxiliary channel when the primary channel is busy; the perception mode includes simultaneous perception and / or time-sharing perception.

[0137] Among them, the simultaneous sensing identifier indicates that the site device 101 supports sensing or channel detection on at least two of the auxiliary channels at the same time; the time-sharing sensing identifier indicates that the site device 101 supports: time-sharing one-to-one sensing or one-to-one channel detection on each of the auxiliary channels.

[0138] The station device 101 and the access point device 102 can communicate under the connection established between them, wherein each connection can have multiple channels, and the multiple channels can include a primary channel and a secondary channel.

[0139] In the existing 802.11 standard, if the primary channel is busy, devices cannot access secondary or non-primary channels for communication, which can lead to low resource utilization. For example, in real-world applications, an AP may support 160MHz bandwidth communication, while a STA may only support 20MHz or 40MHz bandwidth communication. If the 20MHz or 40MHz primary channel bandwidth is busy, the remaining 140MHz or 120MHz bandwidth cannot be used for communication, resulting in low spectrum utilization.

[0140] In UHR, the transmission delay of some services needs to be guaranteed. If the device access channel method in the existing 802.11 standard is used for service transmission, the service transmission delay will also be extended, which may not meet the low latency requirement. A mechanism is needed to strengthen the device access channel method to meet the low latency requirement.

[0141] Optionally, the perception capability information of the site device 101 or the access point device 102 for listening on the auxiliary channel can be determined based on the number of antennas or SS (spatial stream) supported by the site device 101 or the access point device 102, that is, whether the site device 101 or the access point device 102 supports perception or channel detection on the auxiliary channel.

[0142] Among them, when the site device 101 or the access point device 102 supports perception or channel detection on the auxiliary channel, it can be further determined that the site device 101 or the access point device 102 supports a perception mode for listening on the auxiliary channel, that is, it is determined whether the site device 101 or the access point device 102 supports time-sharing perception on the auxiliary channel, or supports simultaneous perception on the auxiliary channel.

[0143] In some embodiments, the first radio frame includes a sensing capability field; the sensing capability field includes a first sensing capability flag bit and / or a second sensing capability flag bit;

[0144] The first sensing capability flag bit identifies whether the site device supports the simultaneous sensing;

[0145] The second sensing capability flag bit identifies whether the site device supports the time-sharing sensing.

[0146] The first and second sensing capability flags can be identified by bits. For example, the sensing capability field can be set to include two bits, with the first bit being the first sensing capability flag and the second bit being the second sensing capability flag. The sensing capability of the site device can be identified by setting bit parameter values.

[0147] The first bit indicates whether the site device 101 supports simultaneous sensing on the secondary channel when the primary channel is busy. For example, when the first bit is set to "1," it indicates that the site device 101 supports simultaneous sensing on the secondary channel when the primary channel is busy; when the first bit is set to "0," it indicates that the site device 101 does not support simultaneous sensing on the secondary channel when the primary channel is busy.

[0148] The second bit indicates whether the site device 101 supports time-sharing sensing on the secondary channel when the primary channel is busy. For example, when the second bit is set to "1," it indicates that the site device 101 supports time-sharing sensing on the secondary channel when the primary channel is busy; when the second bit is set to "0," it indicates that the site device 101 does not support time-sharing sensing on the secondary channel when the primary channel is busy.

[0149] The setting of the parameter value of the first bit and the setting of the parameter value of the second bit can be independent of each other, that is, the first bit and the second bit can be set to "1" at the same time.

[0150] In the above embodiment, different perception modes are used to identify the specific manner in which the site device 101 perceives or performs channel detection in the auxiliary channel. In this way, the access point device 102 that receives the first wireless frame can negotiate an auxiliary channel for perception or channel detection through the site device 101 according to the perception mode supported by the site device 101 when the primary channel is busy.

[0151] In the disclosed embodiments, sensing modes can be divided into simultaneous sensing and / or time-sharing sensing based on the different sensing or channel detection capabilities of the station device 101 in the secondary channel. The station device 101 carries first identification information in the first radio frame, which identifies the sensing mode in which the station device 101 listens on the secondary channel when the primary channel is busy. Thus, when the primary channel is busy, the station device 101 can listen on the secondary channel based on its corresponding sensing mode and sensing capabilities, paving the way for subsequent communication with the access point device 102 in the secondary channel, improving system throughput and reducing transmission latency for low-latency services. For example, if an AP supports 160MHz bandwidth communication, while a STA only supports 40MHz bandwidth communication, it can determine a 40MHz primary channel and three 40MHz secondary channels. If the 40MHz bandwidth of the primary channel is busy, it can switch to the secondary channel and communicate using the 40MHz bandwidth of the secondary channel. If the STA supports simultaneous sensing, it can simultaneously sense or perform channel detection on the three secondary channels and select a secondary channel for communication based on the sensing results. If the STA supports time-sharing sensing, it can sense each auxiliary channel one by one or perform channel detection one by one, and select an auxiliary channel for communication based on the sensing result.

[0152] Step 202 : The site device 101 sends the first wireless frame to the access point device 102 .

[0153] The access point device 102 is an AP that maintains a communication connection with the station device 101 .

[0154] Station device 101 transmits a first radio frame to access point device 102, informing access point device 102 of a sensing mode in which station device 101 listens on a secondary channel when the primary channel is busy. The sensing mode includes simultaneous sensing and / or time-sharing sensing. Thus, when the primary channel is busy, access point device 102 can negotiate with station device 101 on a secondary channel sensing mode based on station device 101's sensing or channel detection capabilities on the secondary channel. Based on the negotiation result, the station device senses on the secondary channel, thereby communicating with station device 101 on the secondary channel. Communication resources are allocated to station device 101 using different mechanisms, thereby improving resource utilization and increasing the throughput of the communication system, thereby increasing data transmission rate and reducing transmission latency. For example, when access point device 102 needs to transmit downlink low-latency services to station device 101, communication resources for communication on the secondary channel can be allocated to station device 101 using a corresponding mechanism based on the sensing mode in which station device 101 listens on the secondary channel, thereby transmitting the downlink low-latency services and reducing transmission latency.

[0155] In some embodiments, the first radio frame further includes channel parameter information of the auxiliary channel supported by the site device 101 .

[0156] The parameter information of the auxiliary channels may include the number of auxiliary channels. Optionally, the number of auxiliary channels may be set according to the working bandwidth supported by the site device 101 and the working bandwidth supported by the access point device 102.

[0157] For example, if the site device 101 supports a 20 MHz operating bandwidth and the access point device 102 supports a 160 MHz operating bandwidth, one primary channel and a maximum of seven secondary channels can be set. For another example, if the site device 101 supports a 20 MHz operating bandwidth and the access point device 102 supports a 320 MHz operating bandwidth, one primary channel and a maximum of 15 secondary channels can be set.

[0158] In the above embodiment, by setting the channel parameter information of the auxiliary channel supported by the site device in the first radio frame, the access point device that receives the first radio frame can negotiate the auxiliary channel for perception or channel detection through the site device 101 based on the perception mode supported by the site device and the channel parameter information of the auxiliary channel supported by the site device when the primary channel is busy, and adopt different mechanisms to plan communication resources for the site device.

[0159] In some embodiments, the time-sharing sensing includes sensing sequence information;

[0160] The sensing order information identifies a sensing order for sensing or detecting each of the auxiliary channels.

[0161] In some embodiments, the sensing order includes: sensing or performing channel detection according to the order of the central frequencies of the auxiliary channels.

[0162] Among them, the auxiliary channels can be directly arranged in order of their center frequencies, starting from the auxiliary channel with the lowest center frequency in ascending order of the center frequencies, and each auxiliary channel can be sensed or channel detected in turn until the perception of the auxiliary channel with the highest center frequency is completed, and the perception / channel detection (channel assess, CA) process is ended; or the auxiliary channels can be sensed or channel detected in descending order of the center frequencies, starting from the auxiliary channel with the highest center frequency, and each auxiliary channel can be sensed or channel detected in turn until the perception of the auxiliary channel with the lowest center frequency is completed, and the perception / channel detection process is ended. The embodiments of the present disclosure do not limit the specific perception process.

[0163] In the embodiment of the present disclosure, the auxiliary channels and the main channels can also be arranged in order of their center frequencies. With the center frequency of the main channel as the reference point, the auxiliary channels whose center frequencies are lower than the center frequency of the main channel can be sensed or detected first, and then the auxiliary channels whose center frequencies are higher than the center frequency of the main channel can be sensed or detected. Alternatively, the auxiliary channels whose center frequencies are higher than the center frequency of the main channel can be sensed or detected first, and then the auxiliary channels whose center frequencies are lower than the center frequency of the main channel can be sensed or detected. The embodiment of the present disclosure does not limit the specific perception process.

[0164] Among them, for auxiliary channels whose center frequencies are lower than the center frequency of the main channel, the auxiliary channels can be sensed or channel detected in descending order of center frequencies, starting from the auxiliary channel with the highest center frequency, until the auxiliary channel with the lowest center frequency is sensed, and the sensing / channel detection process ends. For auxiliary channels whose center frequencies are higher than the center frequency of the main channel, the auxiliary channels can be sensed or channel detected in ascending order of center frequencies, starting from the auxiliary channel with the lowest center frequency, until the auxiliary channel with the highest center frequency is sensed, and the sensing / channel detection process ends.

[0165] It should be noted that in the embodiments of the present disclosure, when performing sensing or channel detection on auxiliary channels, the sensing process is not limited to ending after completing sensing or channel detection on all auxiliary channels. The above is merely an example. For example, if there are seven auxiliary channels, the sensing process may end after completing sensing or channel detection on three of them. Alternatively, if there are seven auxiliary channels, after completing sensing or channel detection on each auxiliary channel in sequence, if the primary channel is still busy, sensing or channel detection may be performed again on each auxiliary channel.

[0166] In some embodiments, the perception order information is carried in: the first radio frame sent during the initial association process.

[0167] Optionally, the first radio frame may be initiated by the site device 101 or the access point device 102 .

[0168] In some embodiments, the first radio frame includes a secondary channel request frame; the first radio frame is a UHR action frame, and the type of the frame identified in the UHR action frame is the first radio frame.

[0169] The UHR action frame may be provided with a flag bit, and the flag bit may be used to identify the frame type of the UHR action frame as the first radio frame. For example, when the flag bit is set to 1, the frame type of the UHR action frame is the first radio frame.

[0170] Optionally, a secondary channel request frame may be defined, and some fields in the secondary channel request frame may be used to indicate the secondary channel sensing sequence information.

[0171] In some embodiments, the access point device 102 may respond to the received secondary channel request frame via a secondary channel response frame.

[0172] Step 203: The access point device 102 determines a third radio frame; wherein the third radio frame includes second identification information, and the second identification information identifies whether the access point device 102 accepts the request content of the first radio frame.

[0173] The third wireless frame may be a secondary channel response frame, and the second identification information may be indicated by a status field in the secondary channel response frame.

[0174] When the status field is set to success, it indicates that the access point device 102 accepts the request content of the first radio frame, that is, the access point device 102 agrees to perform sensing or channel detection on the auxiliary channel according to the sensing mode, channel parameter information and sensing order information of the auxiliary channel determined by the station device 101 for listening on the auxiliary channel when the primary channel is busy. When the status field is set to declined_with_suggested, it indicates that the access point device 102 does not accept / reject the request content of the first radio frame.

[0175] In some embodiments, the second identification information identifies that the access point device 102 rejects the request content of the first radio frame, and the third radio frame includes auxiliary channel information recommended by the access point device 102.

[0176] The auxiliary channel information may include but is not limited to the sensing mode of the site device 101 monitoring the auxiliary channel when the primary channel is busy, channel parameter information of the auxiliary channel, and sensing sequence information.

[0177] The access point device 102 may determine the secondary channel information recommended by the access point device 102 based on the sensing mode for listening on the secondary channel when the primary channel is busy, the channel parameter information of the secondary channel, and the sensing order information determined by the station device 101. For example, when the sensing order information determined by the station device 101 is to perform sensing or channel detection on the secondary channel in ascending order of the center frequencies of the secondary channels, the secondary channel information recommended by the access point device 102 may be to perform sensing or channel detection on the secondary channel in descending order of the center frequencies of the secondary channels.

[0178] In step 204 , the access point device 102 sends the third wireless frame to the station device 101 .

[0179] In step 205, the site device 101 determines a fourth radio frame; wherein the fourth radio frame includes third identification information; the third identification information identifies that the site device 101 changes the sensing mode and / or the parameters of the auxiliary channel.

[0180] Typically, simultaneous sensing consumes more power than time-sharing sensing, and the duration required for simultaneous sensing is generally shorter than the duration required for time-sharing sensing. In the disclosed embodiment, the station device 101 can determine whether to change the sensing mode and / or the parameters of the auxiliary channel based on service latency requirements and device power consumption requirements during communication with the access point device 102.

[0181] When the site device 101 determines to change the perception mode and / or the parameters of the auxiliary channel, the change information can be identified by fourth identification information, and the fourth identification information can be carried by a fourth radio frame.

[0182] In some embodiments, the fourth radio frame includes a secondary channel change frame;

[0183] The fourth radio frame is an ultra high reliability action frame UHR action frame, and the UHR action frame identifies the type of the frame as the fourth radio frame.

[0184] The UHR action frame may be the aforementioned UHR action frame, or may be a newly defined UHR action frame.

[0185] A flag bit may be set in the UHR action frame to identify whether the frame type of the UHR action frame is the fourth radio frame. For example, when the flag bit is set to 3, the frame type of the UHR action frame is the fourth radio frame.

[0186] Step 206 : The station device 101 sends the fourth wireless frame to the access point device 102 .

[0187] In an embodiment of the present disclosure, the site device 101 notifies the access point device 102 of the sensing mode, channel parameter information of the secondary channel, and sensing order information for time-sharing sensing when the primary channel is busy. The access point device 102 provides feedback to the site device 101 regarding whether it accepts the request content of the first radio frame. This allows the site device 101 and the access point device 102 to negotiate a sensing mode for the site device 101 on the secondary channel. The site device 101 notifies the access point device 102 of changes to the sensing mode and / or parameters of the secondary channel, and renegotiates the sensing mode for the site device 101 on the secondary channel. In this way, when the primary channel is busy, the access point device 102 can negotiate with the site device 101 on the sensing mode for the secondary channel in real time based on the site device 101's sensing or channel detection capability on the secondary channel. Based on the negotiation result, the site device 101 can sense or detect the secondary channel, thereby communicating on the secondary channel based on the sensing result. Communication resources are allocated to the site device 101 using a corresponding mechanism, thereby improving resource utilization, thereby increasing data transmission rate, and reducing transmission latency.
