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, 802.11a, and the next generation 802.11 protocol, but is not limited thereto.

[0130] Optionally, in the embodiments of the present disclosure, the AP and the STA can be devices supporting multi-link, for example, can be respectively denoted as an access point multi-link device (AP MLD) and a non-access point multi-link device (Non-AP MLD); the AP MLD can represent an access point supporting a multi-link communication function, and the non-AP MLD can represent a station supporting a multi-link communication function.

[0131] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions proposed in the embodiments of the present disclosure. It can be known by those skilled in the art that, as the system architecture evolves and new business scenarios appear, the technical solutions proposed in the embodiments of the present disclosure are also applicable to similar technical problems.

[0132] The following embodiments of the present disclosure can be applied to Figure 1 The communication system 100 shown or part of the main body, but not limited thereto. Figure 1 The main body shown is an example, and the communication system can include Figure 1 All or part of the main body in the above, but also can include Figure 1 Other main body, the number and form of each main body is arbitrary, each main body can be real or virtual, the connection relationship between each main body is an example, each main body can not be connected or can be connected, its connection can be any way, can be direct connection or indirect connection, can be wired connection or wireless connection.

[0133] Embodiments of the present disclosure can be applied to a wireless local area network (WLAN), for example, a local area network using 802.11 series protocols. In a WLAN, a basic service set (BSS) is a basic component of a WLAN. A BSS network is composed of station devices having some association within a certain coverage area. One case of association is that the stations directly communicate with each other in an ad hoc network, which is referred to as an independent BSS (IBSS). Another more common case is that there is only one central station having a full-time management BSS in the BSS network, which is referred to as an access point device, and other stations in the BSS network that are not APs are referred to as terminals, also referred to as non-AP STAs. APs and non-AP STAs are collectively referred to as STAs. When describing STAs, it is not necessary to distinguish between APs and non-AP STAs. In the same BSS network, due to distance, transmission power, and the like, one STA cannot detect other STAs far away from it, and the two are each other's hidden nodes.

[0134] Figure 2 is one of the interaction diagrams of the sensing mode negotiation method according to embodiments of the present disclosure. As shown in Figure 2 the above method comprises:

[0135] Step 201, the station device 101 determines a first wireless frame; wherein the first wireless frame comprises first identification information; the first identification information identifies a sensing mode of the station device in an auxiliary channel when a primary channel is busy; the sensing mode comprises simultaneous sensing and / or time-sharing sensing.

[0136] wherein the simultaneous sensing indicates that the station device 101 supports simultaneous sensing or channel detection on at least two auxiliary channels; the time-sharing sensing indicates that the station device 101 supports one-to-one sensing or one-to-one channel detection on each auxiliary channel in a time-sharing manner.

[0137] The station device 101 and the access point device 102 can communicate under a connection established between the two. Wherein there can be multiple channels under each connection, and the multiple channels can include a primary channel and auxiliary channels.

[0138] In the existing 802.11 standard, if the primary channel is busy, the device cannot access the secondary channel or the non-primary channel for communication, which can cause low resource utilization. For example, in actual application, there can be an AP supporting 160MHz bandwidth communication, and a STA can only support 20MHz or 40MHz bandwidth communication. If the primary channel of 20MHz or 40MHz bandwidth is busy, the remaining 140MHz or 120MHz cannot be used for communication, which causes low spectrum utilization.

[0139] In the UHR, the transmission delay of some services needs to be guaranteed. If the device accesses the channel in the existing 802.11 standard, the delay of service transmission will also be prolonged, which can not meet the low delay requirement. Therefore, a mechanism is needed to strengthen the device access to the channel to meet the low delay requirement.

[0140] Optionally, the sensing capability information of the station device 101 or the access point device 102 for listening to the secondary channel can be determined according to the number of antennas or the spatial stream (SS) supported by the station device 101 or the access point device 102, that is, whether the station device 101 or the access point device 102 supports sensing or channel detection on the secondary channel.

[0141] When the station device 101 or the access point device 102 supports sensing or channel detection on the secondary channel, the sensing mode of the station device 101 or the access point device 101 for listening to the secondary channel can be further determined, that is, whether the station device 101 or the access point device 102 supports time-sharing sensing or simultaneous sensing on the secondary channel.

[0142] In some embodiments, the first wireless frame includes a sensing capability field; the sensing capability field includes a first sensing capability identification bit and / or a second sensing capability identification bit;

[0143] The first sensing capability identification bit identifies whether the station device supports the simultaneous sensing;

[0144] The second sensing capability identification bit identifies whether the station device supports the time-sharing sensing.

[0145] The first sensing capability identification bit and the second sensing capability identification bit can be identified by a bit. For example, the sensing capability field can include two bits, and the first bit can be used as the first sensing capability identification bit, and the second bit can be used as the second sensing capability identification bit. The sensing capability of the station device can be identified by setting the parameter value of the bit.

[0146] The first bit indicates whether the station device 101 supports simultaneous sensing on the secondary channel when the primary channel is busy. For example, the first bit can be set to "1" to indicate that the station device 101 supports simultaneous sensing on the secondary channel when the primary channel is busy, and the first bit can be set to "0" to indicate that the station device 101 does not support simultaneous sensing on the secondary channel when the primary channel is busy.

[0147] The second bit indicates whether the station device 101 supports time-sharing sensing on the secondary channel when the primary channel is busy. For example, the second bit can be set to "1" to indicate that the station device 101 supports time-sharing sensing on the secondary channel when the primary channel is busy, and the second bit can be set to "0" to indicate that the station device 101 does not support time-sharing sensing on the secondary channel when the primary channel is busy.

[0148] The first bit and the second bit can be set independently of each other, i.e., the first bit and the second bit can be set to "1" at the same time.

[0149] In the above embodiment, the specific way in which the station device 101 senses or performs channel detection on the secondary channel is indicated by different sensing modes, so that the access point device 102 receiving the first wireless frame can negotiate the secondary channel on which the station device 101 senses or performs channel detection according to the sensing mode supported by the station device 101 when the primary channel is busy.

[0150] In the embodiments of the present disclosure, the sensing mode can be divided into simultaneous sensing and / or time-sharing sensing according to the different abilities of the station device 101 to sense or perform channel detection in the auxiliary channel. The station device 101 carries the first identification information in the first wireless frame, and the first identification information identifies the sensing mode of the station device 101 to listen in the auxiliary channel when the main channel is busy. In this way, when the main channel is busy, the station device 101 can listen in the auxiliary channel according to the corresponding sensing mode and sensing ability, which can improve the throughput of the system and reduce the transmission delay of low-latency services for subsequent communication with the access point device 102 in the auxiliary channel. For example, if the AP supports 160 MHz bandwidth communication, and the STA can only support 40 MHz bandwidth communication, a 40 MHz main channel and three 40 MHz auxiliary channels can be determined. If the 40 MHz bandwidth of the main channel is busy, the station device 101 can switch to the auxiliary channel and communicate through the 40 MHz bandwidth of the auxiliary channel. If the STA supports simultaneous sensing, the STA can simultaneously sense or perform channel detection on the three auxiliary channels, and select one auxiliary channel for communication according to the sensing result. If the STA supports time-sharing sensing, the STA can sense or perform channel detection on each auxiliary channel one by one, and select one auxiliary channel for communication according to the sensing result.

[0151] In step 202, the station device 101 sends the first wireless frame to the access point device 102.

[0152] The access point device 102 is an AP that maintains a communication connection with the station device 101.

[0153] The station device 101 informs the access point device 102 of the sensing mode of the station device 101 to listen in the auxiliary channel when the main channel is busy by sending the first wireless frame to the access point device 102. The sensing mode includes simultaneous sensing and / or time-sharing sensing. In this way, when the main channel is busy, the access point device 102 can negotiate the auxiliary channel sensing mode with the station device 101 according to the ability of the station device 101 to sense or perform channel detection in the auxiliary channel, and then make the station device sense in the auxiliary channel according to the negotiation result, so that the station device 101 communicates in the auxiliary channel. Different mechanisms are used to allocate communication resources to the station device 101, which improves the resource utilization rate, increases the throughput of the communication system, and thus improves the data transmission rate and reduces the transmission delay. For example, when the access point device 102 needs to transmit downlink low-latency services to the station device 101, the access point device 102 can allocate communication resources for the station device 101 to communicate in the auxiliary channel according to the sensing mode of the station device 101 to listen in the auxiliary channel, so as to transmit the downlink low-latency services and reduce the transmission delay.

[0154] In some embodiments, the first wireless frame further comprises channel parameter information of the secondary channel that the station device 101 supports sensing.

[0155] The parameter information of the secondary channel can comprise a number of secondary channels. Alternatively, the number of secondary channels can be set according to the working bandwidth supported by the station device 101 and the working bandwidth supported by the access point device 102.

[0156] For example, in the case that the station device 101 supports a 20MHz working bandwidth and the access point device 102 supports a 160MHz working bandwidth, one primary channel and up to 7 secondary channels can be set. For another example, in the case that the station device 101 supports a 20MHz working bandwidth and the access point device 102 supports a 320MHz working bandwidth, one primary channel and up to 15 secondary channels can be set.

[0157] In the above embodiments, by setting the channel parameter information of the secondary channel that the station device supports sensing in the first wireless frame, the access point device receiving the first wireless frame can negotiate the secondary channel for sensing or channel detection by the station device 101 according to the sensing mode supported by the station device and the channel parameter information of the secondary channel that the station device supports sensing, and plan communication resources for the station device by different mechanisms when the primary channel is busy.

[0158] In some embodiments, the time-sharing sensing comprises sensing sequence information.

[0159] The sensing sequence information identifies the sensing sequence of sensing or detecting each of the secondary channels.

[0160] In some embodiments, the sensing sequence comprises sensing or performing channel detection according to the high-low order of the center frequency points of the secondary channels.

[0161] The center frequency points of the secondary channels can be directly arranged according to the high-low order of the center frequency points, and the sensing or channel detection of each secondary channel can be performed in ascending order of the center frequency points, starting from the secondary channel with the lowest center frequency point, until the sensing of the secondary channel with the highest center frequency point is completed, and the sensing / channel detection (CA) process is ended. Alternatively, the sensing or channel detection of each secondary channel can be performed in descending order of the center frequency points, starting from the secondary channel with the highest center frequency point, until the sensing of the secondary channel with the lowest center frequency point is completed, and the sensing / channel detection process is ended. The specific sensing process is not limited in the embodiments of the present disclosure.

[0162] In the embodiments of the present disclosure, the auxiliary channels can also be arranged according to the center frequency points of the auxiliary channels and the high-low order of the center frequency points of the main channel. The auxiliary channels with the center frequency points lower than the center frequency point of the main channel are sensed or detected first, and then the auxiliary channels with the center frequency points higher than the center frequency point of the main channel are sensed or detected. The auxiliary channels with the center frequency points higher than the center frequency point of the main channel can also be sensed or detected first, and then the auxiliary channels with the center frequency points lower than the center frequency point of the main channel are sensed or detected. The specific sensing process is not limited in the embodiments of the present disclosure.

[0163] For the auxiliary channels with the center frequency points lower than the center frequency point of the main channel, the sensing or channel detection can be performed on each auxiliary channel in descending order of the center frequency points, starting from the auxiliary channel with the highest center frequency point, and ending the sensing / channel detection process after sensing the auxiliary channel with the lowest center frequency point. For the auxiliary channels with the center frequency points higher than the center frequency point of the main channel, the sensing or channel detection can be performed on each auxiliary channel in ascending order of the center frequency points, starting from the auxiliary channel with the lowest center frequency point, and ending the sensing / channel detection process after sensing the auxiliary channel with the highest center frequency point.

[0164] It should be noted that in the embodiments of the present disclosure, the sensing or channel detection of the auxiliary channels is not limited to ending the sensing process after sensing or channel detecting all the auxiliary channels. The above is only an example. For example, in the case of 7 auxiliary channels, the sensing process can be ended after sensing or channel detecting 3 auxiliary channels. In the case of 7 auxiliary channels, the sensing or channel detection of each auxiliary channel can be performed in sequence, and if the main channel is still busy, the sensing or channel detection of each auxiliary channel can be performed again.

[0165] In some embodiments, the sensing order information is carried in the first wireless frame sent in the initial association process.

[0166] Optionally, the first wireless frame can be initiated by the station device 101 or by the access point device 102.

[0167] In some embodiments, the first wireless frame includes a secondary channel request frame, and the first wireless frame is a UHR action frame, and the type of the UHR action frame is identified in the first wireless frame.

[0168] The first wireless frame type can be identified by setting an identification bit in the UHR action frame. For example, when the identification bit is set to 1, the UHR action frame is of the first wireless frame type.

[0169] Optionally, the secondary channel sensing order information can be indicated by defining a secondary channel request frame and by some fields in the secondary channel request frame.

[0170] In some embodiments, the access point device 102 can respond to the received secondary channel request frame by a secondary channel response frame.

[0171] In step 203, the access point device 102 determines a third wireless frame; wherein the third wireless frame includes second identification information, and the second identification information identifies whether the access point device 102 accepts the request content of the first wireless frame.

[0172] The third wireless frame can be a secondary channel response frame, and the second identification information can be indicated by a status field in the secondary channel response frame.

[0173] When the status field is set to success, it indicates that the access point device 102 accepts the request content of the first wireless frame, i.e., the access point device 102 agrees to the sensing mode of the station device 101 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, and performs sensing or channel detection on the secondary channel.

[0174] In some embodiments, the second identification information indicates that the access point device 102 rejects the request content of the first wireless frame, and the third wireless frame includes the secondary channel information recommended by the access point device 102.

[0175] The secondary channel information can include, but is not limited to, the sensing mode of the station device 101 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.

[0176] The access point device 102 can determine the secondary channel information recommended by the access point device 102 according to the sensing mode determined by the station device 101 when the primary channel is busy, the channel parameter information of the secondary channel, and the sensing order information. For example, when the sensing order information determined by the station device 101 is that the sensing or channel detection on the secondary channel is performed in ascending order of the frequency of the center frequency point of the secondary channel, the secondary channel information recommended by the access point device 102 can be that the sensing or channel detection on the secondary channel is performed in descending order of the frequency of the center frequency point of the secondary channel.

[0177] In step 204, the access point device 102 sends a third wireless frame to the station device 101.

[0178] In step 205, the station device 101 determines a fourth wireless frame; the fourth wireless frame includes third identification information; the third identification information identifies that the station device 101 changes the sensing mode and / or the parameter of the secondary channel.

[0179] Generally, the power consumption of simultaneous sensing is greater than that of time-sharing sensing, and the time length required for simultaneous sensing is generally less than that required for time-sharing sensing. In the embodiment of the present disclosure, the station device 101 can determine whether to change the sensing mode and / or the parameter of the secondary channel during the communication with the access point device 102 according to the demand for business time delay and the power consumption requirement of the device.

[0180] When the station device 101 determines to change the sensing mode and / or the parameter of the secondary channel, the change information can be identified by the fourth identification information, and the fourth identification information is carried by the fourth wireless frame.

[0181] In some embodiments, the fourth wireless frame includes a secondary channel change frame.

[0182] The fourth wireless frame is an ultra-high reliability action frame (UHR action frame), and the type of the UHR action frame is identified in the UHR action frame.

[0183] The UHR action frame can be the above-mentioned UHR action frame, or a newly defined UHR action frame.

[0184] The identification bit can be set in the UHR action frame to identify whether the frame type of the UHR action frame is the fourth wireless frame. For example, when the identification bit is set to 3, the frame type of the UHR action frame is the fourth wireless frame.

[0185] In step 206, the station device 101 sends a fourth wireless frame to the access point device 102.

[0186] In the embodiments of the present disclosure, the station device 101 informs the access point device 102 of the sensing mode of the station device 101 in the auxiliary channel when the main channel is busy, the channel parameter information of the auxiliary channel, and the sensing order information of the time-sharing sensing; the access point device 102 feeds back to the station device 101 whether to accept the request content of the first wireless frame, so that the station device 101 and the access point device 102 can negotiate the sensing mode of the station device 101 in the auxiliary channel; the station device 101 informs the access point device 102 of the information that the sensing mode and / or the parameter of the auxiliary channel are changed, so as to re-negotiate the sensing mode of the station device 101 in the auxiliary channel; in this way, when the main channel is busy, the access point device 102 can negotiate the sensing mode of the auxiliary channel with the station device 101 according to the sensing or channel detection capability of the station device 101 in the auxiliary channel in real time, and then according to the negotiation result, the station device 101 senses or performs channel detection in the auxiliary channel, so as to communicate in the auxiliary channel according to the sensing result, and allocate communication resources to the station device 101 by using a corresponding mechanism, thereby improving the resource utilization rate, increasing the data transmission rate, and reducing the transmission delay.
