[0112] FIG. 1 is a schematic diagram of a communication method according to an embodiment of the present disclosure.

[0113] As shown in FIG. 1 , in a WLAN, channels are usually divided into a primary channel and a secondary channel (or non-primary channel, or called a secondary channel, non-primary channel); a primary channel is, for example, the primary 20 MHz channel in FIG. 1 ; wherein, a secondary channel may include one or more sub-channels, for example, a 20 MHz secondary channel and a 40 MHz secondary channel in FIG. 1 .

[0114] In the process of channel competition on the channel, if the main channel is in the OBSS busy state (OBSS interference), as shown in the T1 time period and the T2 time period 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 (PPDU) on the main channel, then the main channel is in the OBSS busy state. If the main channel is in the OBSS busy state, in order to make full use of the channel resources, it can be switched to the auxiliary channel communication to improve the communication system throughput and maximize the channel resource utilization. For example, switch to the 20MHz auxiliary channel communication in the T1 time period, or switch to the 40MHz auxiliary channel communication in the T2 time period.

[0115] If the primary channel is in an idle state, as shown in the T3 time period in the figure, the AP and the STA can send PPDU to each other.

[0116] FIG. 2 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0117] As shown in FIG. 2 , the communication system 100 includes a station device (STA) 101 and an access point device (AP) 102 .

[0118] In some embodiments, the site device 101 includes, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports WiFi communication function. Optionally, the wireless communication terminal is, for example, a mobile phone, a wearable device, an Internet of Things device that supports WiFi communication function, a car with WiFi communication function, a smart car, a tablet computer, a computer with wireless transceiver function, 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 smart grid, a wireless terminal device in transportation safety, a wireless terminal device in smart city, and a wireless terminal device in smart home, but is not limited thereto.

[0119] Specifically, the site device 101 may be a terminal device or a network device with a wireless fidelity (WiFi) chip. Optionally, the site 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, 802.11bn, and support the next generation 802.11 protocol, but is not limited thereto.

[0120] 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 and 802.11a, 802.11bf, 802.11bn, and support the next generation 802.11 protocol, but is not limited to this.

[0121] Optionally, in an embodiment of the present disclosure, AP and STA may be devices supporting multiple connections, for example, they may be respectively 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); AP MLD may represent an access point supporting multi-connection communication functions, and non-AP MLD may represent a site supporting multi-connection communication functions.

[0122] 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. A person of ordinary skill in the art 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.

[0123] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG2 or part of the subject, but are not limited thereto. The subjects shown in FIG2 are examples, and the communication system may include all or part of the subjects in FIG2, or may include other subjects other than FIG2, and the number and form of each subject are arbitrary, and each subject may be physical or virtual, and the connection relationship between the subjects is an example, and the subjects may be connected or disconnected, and the connection may be in any manner, and may be a direct connection or an indirect connection, and may be a wired connection or a wireless connection.

[0124] The embodiments of the present disclosure can be applied to a wireless local area network (WLAN), such as a local area network using 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 case of association is that stations communicate directly with each other in an ad hoc network, which is called an independent BSS (IBSS). Another more common case is that there is only one central station in the BSS network that is dedicated to managing the BSS, which is called an access point device, and all other STAs in the network are associated with it. Other stations in the BSS network that are not central stations are called terminals, also called non-AP STAs, and 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, etc., a STA cannot detect other STAs that are far away from it, and the two are hidden nodes of each other.

[0125] As shown in FIG. 2 , the method includes:

[0126] In step 201, the access point device 102 determines a first wireless frame; wherein the first wireless frame is used to trigger the site device to switch to the auxiliary channel communication when the main channel is busy; the first wireless frame includes first identification information, and the first identification information identifies the bandwidth information of the auxiliary channel negotiated by the access point device and the site device.

[0127] In WLAN, channels are usually divided into primary channels and secondary channels (or non-primary channels); the secondary channels can contain one or more sub-channels. For example, if the basic bandwidth unit is 20MHz, 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 in a BSS. Stations in the BSS can compete for channels on the primary 20MHz channel to seize channel resources.

[0128] In the process of channel competition on the channel, if the main channel is in the OBSS busy state, for example, it is occupied by other devices in the same OBSS as the access point device 102, and other devices send physical layer protocol data units (PPDU) on the main channel, then the main channel is in the OBSS busy state. If the main channel is in the OBSS busy state, in order to make full use of channel resources, it can be switched to the auxiliary channel to communicate with the site device 101, and the site device 101 is scheduled to the auxiliary channel, and data is sent and received with the site device 101, so as to improve the communication system throughput and maximize the utilization of channel resources.

[0129] In an embodiment of the present disclosure, in order to switch to an auxiliary channel for communication when the main channel is busy, the access point device 102 determines a first wireless frame; wherein the first wireless frame is used to trigger the site device to switch to the auxiliary channel for communication when the main channel is busy; optionally, the first wireless frame may be a trigger frame, such as a multi-user request to send (MU-RTS) or a buffer status report poll (BSRP) frame.

[0130] The first radio frame includes first identification information, the first identification information identifies bandwidth information of the auxiliary channel negotiated between the access point device and the site device, and the bandwidth information is a communication bandwidth value of the auxiliary channel negotiated between the access point device 102 and the site device 101, such as uplink bandwidth information (UL Bandwidth, UL BW) or downlink bandwidth information (DL Bandwidth, DL BW). Optionally, taking UL BW as an example, two bits can be used in the first radio frame to identify the value of UL BW, for example, "00" identifies 20MHz, "01" identifies 40MHz, "10" identifies 80MHz, and "11" identifies 160MHz.

[0131] Taking the first radio frame as a MU-RTS frame or a BSRP frame as an example, the first identification information may be carried in a common information common info field of the first radio frame.

[0132] Step 202: The access point device 102 sends the first radio frame on the auxiliary channel.

[0133] The access point device 102 sends the first radio frame in the auxiliary channel, so that when the main channel is busy, the WLAN device can communicate in the auxiliary channel. For example, when non-periodic data transmission occurs between the access point device 102 and the site device 101, or when the access point device 102 has downlink data to send to the site device 101, when the WLAN device senses that the main channel is busy, it can switch to the auxiliary channel to send MU-RTS frames or BSRP frames, and the site device 101 listens to and receives the first radio frame on the auxiliary channel, determines the parameter information of the auxiliary channel according to the first identification information in the first radio frame, and communicates in the auxiliary channel according to the parameter information, so as to improve the throughput of the communication system and maximize the utilization of channel resources.

[0134] Step 203: The station device 101 receives the first radio frame on the auxiliary channel.

[0135] Optionally, the site device 101 listens to the auxiliary channel and receives the first wireless frame, and can reply a clear to send (CTS) frame to the access point device 102, so that the access point device 102 confirms that the auxiliary channel is idle according to the CTS frame and can send data to achieve communication on the auxiliary channel.

[0136] In some embodiments, the first identification information is carried in a common info field of the first radio frame;

[0137] The bandwidth information includes one or more bandwidth values.

[0138] The first identification information may be carried in the common info field of the first radio frame; the bandwidth information is the communication bandwidth value of the auxiliary channel negotiated between the access point device 102 and the site device 101, such as uplink bandwidth information (UL Bandwidth, UL BW) or downlink bandwidth information (DL Bandwidth, DL BW). The bandwidth information includes one or more bandwidth values. Taking UL BW as an example, two bits may be used in the common info field to identify the value of UL BW, for example, "00" identifies 20MHz, "01" identifies 40MHz, "10" identifies 80MHz, and "11" identifies 160MHz. By negotiating the bandwidth information of the auxiliary channel, the mechanism of communication of the WLAN device in the auxiliary channel is further improved to improve the throughput of the communication system.

[0139] In some embodiments, the first wireless frame includes second identification information, and the second identification information identifies that the type of the first wireless frame is a setup frame for triggering switching to the auxiliary channel communication. For example, the first wireless frame can be a MU-RTS frame or a BSRP frame for triggering switching to the auxiliary channel communication.

[0140] In some embodiments, the second identification information is carried in a user info field of the first radio frame;

[0141] The second identification information is carried in the user info field of the first wireless frame, and the frame type of the first wireless frame is identified by one bit in the user info field.

[0142] The user info field also includes parameter information of the auxiliary channel. By identifying the parameter information of the auxiliary channel, the communication mechanism of the WLAN device on the auxiliary channel is further improved.

[0143] In some embodiments, the parameter information includes at least one of the following:

[0144] Channel identification (channel ID) information, spatial stream information, Association Identifier (AID) information of the site equipment, and Modulation and Coding Scheme (MCS) information.

[0145] Among them, the channel ID can be determined by the access point device 102 and the site device 101 during the initial association process; the spatial stream information can be identified in the form of SS allocation information, such as parameter information such as the number of spatial streams (NSS); the AID information can be allocated by the access point device 102 to the site device 101 during the initial association process; the MCS information includes the MCS mode, such as the modulation mode, the transmission power, etc.; under normal circumstances, the communication environment between the main channel and the auxiliary channel changes little, then the MCS mode of the auxiliary channel can be the same as the MCS mode in the main channel.

[0146] Step 204, the site device 101 sends a second radio frame; wherein the second radio frame identifies that the site device communicates on the auxiliary channel; wherein the second radio frame includes a CTS frame and / or a QoS null frame, and the QoS null frame carries a BSR field.

[0147] The station device 101 monitors the auxiliary channel and receives the first radio frame, and can reply to the access point device 102 with a second radio frame, where the second radio frame indicates that the station will communicate on the auxiliary channel;

[0148] Optionally, the second wireless frame includes a CTS frame and / or a null quality of service (Quality of Service-null, QoS null) frame, the QoS null frame carries a buffer status report (buffer status report, BSR) field, and the BSR field identifies the buffer status information of the site device 101.

[0149] Step 205, the access point device 102 receives a second wireless frame sent by the site device 101; wherein the second wireless frame indicates that the site device communicates on the auxiliary channel;

[0150] The second radio frame includes a CTS frame and / or a QoS null frame, and the QoS null frame carries a BSR field, indicating that the site device 101 communicates on the auxiliary channel.

[0151] Step 206: The site device 101 sends a third radio frame, where the third radio frame indicates that the site device has completed communication on the auxiliary channel.

[0152] The third radio frame includes a PS field; the station device and the access point device negotiate a power saving (PS) mode with the access point device 102 in advance, and the PS field indicates that the station device enters the PS mode after switching to the primary channel.

[0153] If the station device and the access point device have negotiated the PS mode in the primary channel in advance, the station device 101 switches back to the primary channel and enters the PS mode after completing the communication in the auxiliary channel.

[0154] Optionally, the third wireless frame may be an ACK frame, and the PS field of the MAC frame header of the ACK frame may be set to "1" to indicate that it enters the PS mode in the primary channel.

[0155] Step 207: The access point device 102 receives a third radio frame sent by the station device, where the third radio frame indicates that the station device has completed communication on the auxiliary channel.

[0156] The third wireless frame includes a PS field; the site device pre-negotiates a PS mode with the access point device, and the PS field indicates that the site device enters the PS mode after switching to the primary channel.

[0157] After receiving the third radio frame sent by the station device, the access point device 102 confirms that the station device 101 completes the communication on the primary channel and switches back to the primary channel, and then enters the PS mode.

[0158] Optionally, after receiving the third radio frame, the access point device 102 may reply a confirmation frame to the station device 101 to respond to the third radio frame.

[0159] In some embodiments, the method further comprises:

[0160] The access point device 102 receives on the primary channel: a data frame sent by the site device through an enhanced distributed channel access (EDCA) mechanism, and / or a PS mode confirmation message frame sent by the site device; wherein the communication duration of the site device on the auxiliary channel exceeds the NAV setting duration of the primary channel.

[0161] Normally, the communication duration between the access point device 102 and the site device 101 in the auxiliary channel does not exceed the duration set by the Network Allocation Vector (NAV) of the main channel. If the communication duration in the auxiliary channel is longer than the NAV duration set in the main channel it perceives, the site device 101 can only send data frames with the NAV duration set, and the site device 101 needs to switch to the main channel to continue communicating; for example, re-access the channel through the EDCA mechanism to continue sending data frames. Optionally, the site device 101 also completes the PS confirmation mechanism through a PS mode confirmation message frame on the main channel; for example, the PS mode confirmation message frame indicates that after the site device 101 switches to the main channel for communication, it does not enter the PS mode and remains in the awake state.

[0162] The access point device 102 receives the data frame sent by the site device 101 through the EDCA mechanism on the main channel, indicating that the site device 101 continues to send data frames on the main channel; the access point device 102 receives the PS mode confirmation message frame sent by the site device 101 on the main channel, indicating that the site device 101 does not enter the PS mode after switching to the main channel communication.
