[0168] 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.

[0169] 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.

[0170] 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.

[0171] 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.

[0172] FIG. 3 is one of schematic diagrams of a communication method according to an embodiment of the present disclosure. As shown in FIG. 3 , the method includes:

[0173] Step 301: The access point device determines a first radio frame on the auxiliary channel; wherein the first radio frame is used to request the site device to receive data on the auxiliary channel or to feed back buffer status information on the auxiliary channel.

[0174] In WLAN, channels are usually divided into primary channels and secondary channels (or non-primary channels); wherein, the secondary channel may 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 included as 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 access the channel through random competition on the primary 20MHz channel to obtain channel resources.

[0175] In the process of random competition on the channel, if the main channel is in the OBSS (overlapping basic service set) 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.

[0176] In the disclosed embodiment, the access point device 102 senses whether the main channel is busy. Usually, each site device on the network must listen to whether there is other data being transmitted on the channel before sending data, for example, through the energy detection (ED) mechanism at the physical layer and the NAV (Network Allocation Vector) setting mechanism at the MAC layer. When the access point device 102 senses that the main channel is busy, it switches to the auxiliary channel to determine and send a first wireless frame, and requests the site device to send a data frame or cache information through the first wireless frame.

[0177] Optionally, the first wireless frame may include a request to send (RTS) frame or a buffer status report poll (BSRP) control frame, and the first wireless frame is used to request the site device to receive data on the auxiliary channel or to feedback buffer status information on the auxiliary channel.

[0178] Step 302: Send the first radio frame on the auxiliary channel when the listening period arrives; wherein the listening period is pre-negotiated with the site device.

[0179] When the access point device 102 sends an RTS frame or a BSRP control frame on the auxiliary channel, the site device 101 may not be able to receive the first radio frame; for example, due to the existence of hidden nodes, other hidden nodes communicate with the site device 101, which interferes with the site device 101's perception of the busy state of the main channel. Therefore, when the access point device 102 senses that the main channel is busy and switches to the auxiliary channel to send the first radio frame, the site device 101 may not be able to sense that the main channel is busy, and the site device 101 will not switch to the auxiliary channel, but will wait on the main channel for the access point device 102 to send the first radio frame, resulting in unnecessary device power consumption, resulting in an increase in data transmission delay, and may not meet the delay requirement.

[0180] In the disclosed embodiment, when the access point device 102 senses that the main channel is busy, it switches to the auxiliary channel to determine the first radio frame, and sends the first radio frame on the auxiliary channel at the time when the listening cycle arrives, and requests the site device to send a data frame or cache information through the first radio frame. The listening cycle is a period for listening on the auxiliary channel that is pre-negotiated with the site device 101, and the listening cycle can be a period for the site device 101 to listen to the auxiliary channel. At the time when each listening cycle arrives, the site device 101 will listen to the auxiliary channel and receive the first radio frame on the auxiliary channel to avoid the situation where the site device 101 cannot receive the first radio frame, thereby realizing communication in the auxiliary channel, so as to improve the throughput of the communication system and maximize the utilization of channel resources.

[0181] It can be understood that the arrival time of each listening cycle may be the start time of each listening cycle, such as a period before the start of a new listening cycle, such as the first N milliseconds or microseconds.

[0182] Among them, in step 302, step 3021 or step 3022 is executed respectively according to the perception mode of the auxiliary channel.

[0183] Step 3021: The sensing mode of the auxiliary channel includes simultaneous sensing, and when the listening cycle arrives, the first wireless frame is sent simultaneously on each of the auxiliary channels.

[0184] The simultaneous sensing means that the site equipment supports sensing on at least two of the auxiliary channels at the same time;

[0185] If at least two of the auxiliary channels support simultaneous sensing, the access point device 102 may simultaneously send the first radio frame on each auxiliary channel that supports simultaneous sensing.

[0186] Step 3022: The perception mode of the auxiliary channel includes time-sharing perception, and the first wireless frame is sent on each auxiliary channel respectively when the listening cycle of each auxiliary channel arrives.

[0187] The time-sharing sensing indicates that the site device supports: sensing on each auxiliary channel respectively. In this way, the access point device 102 can send the first wireless frame at the time when the listening cycle of each auxiliary channel arrives; that is, for different auxiliary channels, the first wireless frame is sent on the auxiliary channel at the time when the respective listening cycles arrive.

[0188] Optionally, there may be a time offset between the auxiliary channels. For example, if the site device 101 performs a backoff operation in the auxiliary channel 1, there will be a deviation in the transmission time in the auxiliary channel 2. In this case, the time of each auxiliary channel can be based on the time synchronization function (TSF) parameters between the main channels.

[0189] In some embodiments, the sensing mode of the auxiliary channel includes simultaneous sensing, and the listening period of each of the auxiliary channels is the same;

[0190] The sensing mode of the auxiliary channel includes time-sharing sensing, and the listening period of each auxiliary channel is different;

[0191] or

[0192] The sensing mode of the auxiliary channel includes time-division sensing, and at least two adjacent sensing cycles in sensing order have the same interval.

[0193] Among them, the sensing mode of the auxiliary channel includes simultaneous sensing, and the listening period of each auxiliary channel is the same, that is, the starting time, ending time and duration of the listening period are all the same.

[0194] The sensing mode of the auxiliary channel includes time-sharing sensing, and the listening period of each auxiliary channel is different, so as to distinguish the listening periods of different auxiliary channels and avoid overlap between the listening periods of different auxiliary channels.

[0195] The sensing mode of the auxiliary channel includes time-sharing sensing, and the listening order of each auxiliary channel can be set; and the time intervals between adjacent listening cycles can be the same. For example, the listening cycle of auxiliary channel 1 is listening cycle 1, the listening cycle of auxiliary channel 2 is listening cycle 2, and the listening cycle of auxiliary channel 3 is listening cycle 3; wherein the time interval between listening cycle 1 and listening cycle 2 is the same as the time interval between listening cycle 2 and listening cycle 3.

[0196] The time interval between adjacent listening cycles may be the time interval between the end time of a previous listening cycle and the start time of a next listening cycle.

[0197] In some embodiments, the duration of the first radio frame is less than or equal to a set duration of a primary channel network allocation vector NAV.

[0198] Normally, the communication duration on the auxiliary channel does not exceed the communication time on the main channel; therefore, the duration of the first wireless frame is less than or equal to the set duration of the network allocation vector (NAV) of the main channel, so as to avoid the situation where the communication on the auxiliary channel has not yet ended, but the NAV of the main channel ends, and the site device 101 or the access point device 102 re-accesses the main channel, causing communication interruption on the auxiliary channel or other situations.

[0199] In some embodiments the method further comprises:

[0200] During or after the initial association process, the listening period information of the auxiliary channel is negotiated; wherein the listening period information uses the time synchronization function TSF parameter of the primary channel as a time reference.

[0201] Among them, during the initial association process or after the initial association, for example, through negotiation with a third wireless frame; the third wireless frame includes at least one of a beacon frame, a probe response frame, an association response frame or a newly defined wireless frame; for example, during the initial association process, the access point device 102 and the site device 101 negotiate the listening capability information of the access point device 102 through at least one of the aforementioned beacon frame, probe response frame, and association response frame; the newly defined wireless frame is a wireless frame sent after the initial association, and after the initial association, the listening period information of the access point device 102 is negotiated through the newly defined wireless frame.

[0202] The listening cycle information uses the time synchronization function TSF parameter of the primary channel as a time reference, and the listening cycle information may be carried in the association response frame, for example, the listening cycle time finally executed is determined by the association response.

[0203] The communication method involved in the embodiments of the present disclosure may include at least one of the aforementioned steps and embodiments. For example, step 301 may be implemented as an independent embodiment, step 302 may be implemented as an independent embodiment, step 3021 may be implemented as an independent embodiment, and step 3022 may be implemented as an independent embodiment; the combination of step 301 and step 302 may be implemented as an independent embodiment, the combination of step 301 and step 3021 may be implemented as an independent embodiment, and the combination of step 301 and step 3022 may be implemented as an independent embodiment, but is not limited thereto.

[0204] In some embodiments, reference may be made to other optional implementations recorded before or after the description corresponding to FIG. 3 .

[0205] FIG. 4 is one of schematic diagrams of a communication method according to an embodiment of the present disclosure. As shown in FIG. 4 , the method includes:

[0206] Step 401: The site device determines a second radio frame on the auxiliary channel; wherein the second radio frame is used to request the access point device to receive data on the auxiliary channel.

[0207] 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 randomly compete on the primary 20MHz channel to seize channel resources.

[0208] In the process of random 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.

[0209] Generally, each station device on the network must listen to whether there is other data being transmitted on the channel before sending data, for example, through an energy detection (ED) mechanism. The station device 101 determines and sends a second wireless frame on the auxiliary channel, and requests the access point device 102 to send a data frame through the second wireless frame.

[0210] Optionally, the second radio frame may include a request to send (RTS) frame.

[0211] Step 402: Send the second radio frame on the auxiliary channel when the listening period arrives; wherein the listening period is pre-negotiated with the access point device.

[0212] When the access point device 102 sends an RTS frame or a BSRP control frame on the auxiliary channel, the site device 101 may not be able to receive the second radio frame; for example, due to the existence of hidden nodes, other hidden nodes communicate with the site device 101, interfering with the site device 101's perception of the busy state of the primary channel. Therefore, when the access point device 102 senses that the primary channel is busy and switches to the auxiliary channel to send the second radio frame, the site device 101 may not be able to sense that the primary channel is busy, and the site device 101 will not switch to the auxiliary channel, but will wait on the primary channel for the access point device 102 to send the second radio frame, resulting in unnecessary device power consumption, resulting in an increase in data transmission delay, and may not meet the delay requirement.

[0213] In the embodiment of the present disclosure, the site device 101 sends the second radio frame on the auxiliary channel at the time of each listening cycle, and requests the access point device to send a data frame through the second radio frame. The listening cycle is pre-negotiated with the site device 101, and the listening cycle can be a cycle for the site device 101 to listen to the auxiliary channel. At the time of each listening cycle, the site device 101 will listen to the auxiliary channel and receive the second radio frame on the auxiliary channel to avoid the situation where the site device 101 cannot receive the second radio frame, thereby realizing communication in the auxiliary channel, so as to improve the throughput of the communication system and maximize the utilization of channel resources.

[0214] It can be understood that the arrival time of each listening cycle may be the start time of each listening cycle, such as a period of time before the start of a new listening cycle, such as the first N milliseconds.

[0215] Among them, in step 402, step 4021 or step 4022 is executed respectively according to the perception mode of the auxiliary channel.

[0216] Step 4021: The sensing mode of the auxiliary channel includes simultaneous sensing, and when the listening cycle arrives, the second wireless frame is sent simultaneously on each of the auxiliary channels.

[0217] The simultaneous sensing means that the site device 101 supports sensing on at least two of the auxiliary channels at the same time;

[0218] If at least two of the auxiliary channels support simultaneous sensing, the site device 101 may simultaneously send the second radio frame on each auxiliary channel supporting simultaneous sensing.

[0219] Step 4022: The perception mode of the auxiliary channel includes time-sharing perception, and the second wireless frame is sent on each auxiliary channel respectively when the listening cycle of each auxiliary channel arrives.

[0220] The time-division sensing indicates that the site device supports: sensing on each auxiliary channel respectively. In this way, the site device 101 can send the second radio frame at the time when the listening cycle of each auxiliary channel arrives; that is, for different auxiliary channels, at the time when the respective listening cycles arrive, the second radio frame is sent on the auxiliary channel.

[0221] Optionally, there may be a time offset between the auxiliary channels. For example, if the site device 101 performs a backoff operation in the auxiliary channel 1, there will be a deviation in the transmission time in the auxiliary channel 2. In this case, the time of each auxiliary channel can be based on the time synchronization function (TSF) parameters between the main channels.

[0222] In some embodiments, the sensing mode of the auxiliary channel includes simultaneous sensing, and the listening period of each of the auxiliary channels is the same;

[0223] The sensing mode of the auxiliary channel includes time-sharing sensing, and the listening period of each auxiliary channel is different;

[0224] or

[0225] The sensing mode of the auxiliary channel includes time-division sensing, and at least two adjacent sensing cycles in sensing order have the same interval.

[0226] Among them, the sensing mode of the auxiliary channel includes simultaneous sensing, and the listening period of each auxiliary channel is the same, that is, the starting time, ending time and duration of the listening period are all the same.

[0227] The sensing mode of the auxiliary channel includes time-sharing sensing, and the listening period of each auxiliary channel is different, so as to distinguish the listening periods of different auxiliary channels and avoid overlap between the listening periods of different auxiliary channels.

[0228] The sensing mode of the auxiliary channel includes time-sharing sensing, and the listening order of each auxiliary channel can be set; and the time intervals between adjacent listening cycles can be the same. For example, the listening cycle of auxiliary channel 1 is listening cycle 1, the listening cycle of auxiliary channel 2 is listening cycle 2, and the listening cycle of auxiliary channel 3 is listening cycle 3; wherein the time interval between listening cycle 1 and listening cycle 2 is the same as the time interval between listening cycle 2 and listening cycle 3.

[0229] The time interval between adjacent listening cycles may be the time interval between the end time of a previous listening cycle and the start time of a next listening cycle.

[0230] In some embodiments, the duration of the second radio frame is less than or equal to a set duration of a primary channel network allocation vector NAV.

[0231] Normally, the communication duration on the auxiliary channel does not exceed the communication time on the main channel; therefore, the duration of the second wireless frame is less than or equal to the set duration of the network allocation vector (NAV) of the main channel, so as to avoid the situation where the communication on the auxiliary channel has not yet ended, but the NAV of the main channel ends, and the site device 101 or the access point device 102 re-accesses the main channel, causing communication interruption on the auxiliary channel or other situations.
