[0118] In some embodiments, the access point device 101 can be an access point for a mobile terminal to enter a wired network. The AP is equivalent to a bridge connecting the wired network and the wireless network, and its main function is to connect various wireless network clients together and then access the Ethernet network through the wireless network.

Optionally, the wireless communication terminal can be at least one of a mobile phone, a wearable device, an Internet of Things (IoT) device supporting Wi-Fi communication function, a car with Wi-Fi communication function, a smart car, a tablet (Pad), 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.

[0120] Specifically, the station device 102 can be a terminal device or a network device with a wireless fidelity (Wi-Fi) chip. Optionally, the station device 102 can 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 the next generation 802.11 protocol, but is not limited thereto.

[0121] Optionally, in the embodiments of the present disclosure, the number of STAs 102 associated with the AP 101 can include at least two.

[0122] 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.

[0123] 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.

[0124] The embodiments of the present disclosure described below can be applied to the communication system 100 shown in FIG. 1 or part of the subjects, but are not limited thereto. The subjects shown in FIG. 1 are examples, and the communication system can include all or part of the subjects in FIG. 1, or other subjects other than those in FIG. 1. The number and form of each subject is arbitrary, each subject can be real or virtual, the connection relationship between each subject is an example, each subject can not be connected or can be connected, and the connection can be in any way, can be direct connection or indirect connection, can be wired connection or wireless connection.

[0125] The embodiments of the present disclosure can be applied to a Wireless Local Area Network (WLAN), for example, a local area network using an 802.11 series protocol. In the 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 situation of association is that the stations directly communicate with each other in an ad hoc network, which is referred to as an Independent Basic Service Set (IBSS). Another more common situation 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 the other stations in the BSS network that are not APs are referred to as terminals, also referred to as non-AP STAs, and the AP and the non-AP STA are collectively referred to as STAs. When describing the STA, it is not necessary to distinguish between the AP and the non-AP STA. 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.

[0126] FIG. 2 is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2, the above method comprises:

[0127] In step 201, the AP 101 determines a first wireless frame; wherein the first wireless frame identifies: channel resource information allocated by the AP 101 to at least two STAs 102 respectively; wherein the channel of at least one of the STAs 102 is a secondary channel of the AP 101.

[0128] In WLAN, a channel is usually divided into a primary channel and a secondary channel (or non-primary channel, also known as auxiliary channel or non-main channel); wherein the secondary channel can contain one or more sub-channels. For example, if 20MHz is taken as the basic bandwidth unit, when the channel bandwidth is 20MHz, there is only one primary channel with a bandwidth of 20MHz; when the channel bandwidth is greater than 20MHz, one of the 20MHz channels is taken as the primary channel, and the remaining one or more 20MHz channels are taken as auxiliary channels. The primary 20MHz channel is the common channel of operation for STAs 102 that are members of the basic service set, and the stations in the BSS can compete for channel resources on the primary 20MHz channel.

[0129] As an example, as shown in FIG. 4, the primary channel is, for example, the primary 20MHz channel in FIG. 4; wherein the secondary channel can contain one or more sub-channels, for example, the 20MHz secondary channel and the 40MHz secondary channel in FIG. 4.

[0130] In actual Wi-Fi applications, the communication capability value supported by the AP can always be greater than the communication capability value supported by the STA, and the AP and the STA can only communicate at the communication capability value supported by the STA, resulting in waste of the communication resources supported by the AP and greater than the communication capability value supported by the STA. For example, if the AP supports a communication bandwidth of 320MHz, and the STA supports a maximum communication bandwidth of 80MHz or 160MHz, if the AP communicates with the STA, the maximum communication bandwidth that can be used is 160MHz, and the other 160MHz supported by the AP cannot be used, resulting in waste of communication resources.

[0131] Optionally, in some embodiments, the working bandwidth supported by the AP 101 can be a large bandwidth, for example, the working bandwidth supported by the AP 101 is 320MHz or 160MHz.

[0132] Optionally, the communication method provided by the embodiments of the present disclosure is suitable for both devices supporting multi-link communication and devices not supporting multi-link communication.

[0133] If the AP 101 is attached to an AP MLD and the STA 102 is attached to a non-AP MLD, the working bandwidth supported by the AP 101 can be the same or different under each link, which is not limited by the embodiments of the present disclosure. In this specification, the operation under each link is taken as an example for description.

[0134] Optionally, the AP 101 can obtain a TXOP (transmission opportunity) through an EDCA (Enhanced Distributed Channel Access) mechanism, and generate a first wireless frame after obtaining the TXOP.

[0135] In some embodiments, the first wireless frame includes an initial control frame, for example, which can include but is not limited to a MU-RTS (multi user-request to send) frame and a BSRP (Buffer state Reports Polling Frames) frame.

[0136] Optionally, the channel resource information allocated by the AP 101 for each STA 102 can include but is not limited to: identification information of each STA 102, channel information allocated by the AP 101 for each STA 102 for communication with the AP 101, and channel information allocated by the AP 101 for each STA 102 for responding to the first wireless frame, etc. For each STA 102, the channel information allocated by the AP 101 for the STA 102 should be less than or equal to the channel information supported by the STA 102.

[0137] In the above embodiments, the channel resource information allocated by the AP 101 for at least two STAs 102 is identified through the first wireless frame; wherein the channel of at least one STA 102 is a secondary channel of the AP 101; therefore, the channel resource can be allocated to the STA 102 according to the secondary channel of the AP 101, so that the AP 101 respectively communicates with different STAs 102 on the secondary channel or the primary channel of the AP 101, and the spectral utilization of the working bandwidth of the AP 101 is improved.

[0138] Optionally, in some embodiments, the first wireless frame includes any one or a combination of the following:

[0139] a first identification information and a second identification information; wherein the first identification information is used to identify the identification information of the STA 102; and the second identification information is used to identify the communication channel of the STA 102;

[0140] a third identification information; wherein the third identification information is used to identify the channel allocated by the AP 101 to the STA 102 for responding to the first wireless frame;

[0141] a fourth identification information; wherein the fourth identification information is used to identify the time delay information of the channel switching of the AP 101.

[0142] Optionally, the first wireless frame includes a user information field (user info), and the first identification information and the second identification information can be carried in the user info field.

[0143] Optionally, in the first wireless frame, the channel resource information allocated by the AP 101 to at least two STAs 102 can be included, that is, in the first wireless frame, there is a user info field corresponding to each STA 102, and the user info field corresponding to each STA 102 includes the first identification information and the second identification information corresponding to the STA 102.

[0144] Optionally, when the AP 101 allocates channel resource information to at least two STAs 102, the entire channel bandwidth can be allocated to the STA 102 according to the working bandwidth supported by the AP, or the channel bandwidth can be divided into multiple RUs (resource units)

for example, 26-tone RU, 52-tone RU, 106-tone RU, 242-tone RU, etc.; wherein tone represents the number of subcarriers, and 26-tone RU means 26 subcarriers

[0145] Optionally, the entire channel bandwidth can be allocated to the STA, or the RUs, MRUs or dRUs in the channel bandwidth can be allocated to the STA, for example, for a 40MHz channel bandwidth, the entire bandwidth can be allocated to the STA, or 106-tone can be allocated to the STA, or 106+52-tone, or 106-tone dRUs can be allocated to the STA.

[0146] As an example, if the supported working bandwidth of the AP is 40MHz, the 40MHz channel bandwidth can be directly allocated to the STA 102; or, a 106-tone RU can be allocated to the STA1, a 106-tone RU+52-tone RU can be allocated to the STA2, and a 106-tone RU can be allocated to the STA3.

[0147] For example, when the AP 101 allocates channel resource information to 3 STAs 102 (STA1, STA2, STA3) respectively, the first wireless frame includes a user info field corresponding to the STA1, a user info field corresponding to the STA2, and a user info field corresponding to the STA3. The user info field corresponding to the STA1 includes first identification information and second identification information corresponding to the STA1, the user info field corresponding to the STA2 includes first identification information and second identification information corresponding to the STA2, and the user info field corresponding to the STA3 includes first identification information and second identification information corresponding to the STA3. For the STA1, the first identification information corresponding to the STA1 is used to identify the identification information of the STA1, and the second identification information corresponding to the STA1 is used to identify the communication channel allocated by the AP 101 to the STA1.

[0148] Optionally, the identification information of the STA 102 can include but is not limited to the AID (association Identifier) of the STA 102 and the MAC address of the STA 102. Optionally, if the STA 102 is attached to a non-AP MLD, the identification information of the STA 102 can also be the MAC address of the STA 102 under this link. The AID of the STA 102 is the unique identification of the STA 102, regardless of whether the AP 102 only supports single-link communication or the AP 102 supports multi-link communication (for example, the AP 102 is attached to an AP MLD).

[0149] Optionally, the bandwidth of the communication channel allocated by the AP 101 to the STA 102 corresponds to a bandwidth less than or equal to the maximum operating bandwidth supported by the STA 102. For example, if the AP 101 supports an operating bandwidth of 320 MHz, the STA 1 supports a maximum operating bandwidth of 160 MHz, and the STA 2 supports a maximum operating bandwidth of 160 MHz, the AP 101 can allocate a P160 MHz (i.e., a primary channel of 160 MHz) to the STA 1, i.e., allocate resources of the P160 MHz to the STA 1 for uplink and downlink communication; and the AP 101 can allocate a S160 MHz (i.e., a secondary channel of 160 MHz) to the STA 2, i.e., allocate resources of the S160 MHz to the STA 2 for uplink and downlink communication.

[0150] Optionally, the third identification information can also be carried in the user info field of the first wireless frame.

[0151] Optionally, referring to the above-described allocation manner of the communication channel, the AP 101 can allocate a channel for responding to the first wireless frame to each of the at least two STAs 102, which will not be described herein.

[0152] Optionally, for each STA 102, the communication channel allocated by the AP 101 to the STA 102 can be associated with the channel allocated by the AP 101 to the STA 102 for responding to the first wireless frame.

[0153] For example, in the case where the AP 101 allocates resources of the P160 MHz to the STA 1 for uplink and downlink communication, the AP 101 can also allocate resources of the P160 MHz to the STA 1 for responding to the first wireless frame. For another example, in the case where the AP 101 allocates resources of the P160 MHz to the STA 1 for uplink and downlink communication, the AP 101 can also allocate resources of P80 MHz in the P160 MHz (i.e., a primary channel of 80 MHz in the primary 160 MHz channel) to the STA 1 for responding to the first wireless frame.

[0154] For example, in the case where the AP 101 allocates resources of the S160 MHz to the STA 2 for uplink and downlink communication, the AP 101 can also allocate resources of the S160 MHz to the STA 2 for responding to the first wireless frame. For another example, in the case where the AP 101 allocates resources of the S160 MHz to the STA 2 for uplink and downlink communication, the AP 101 can also allocate resources of P80 MHz in the S160 MHz (i.e., a primary channel of 80 MHz in the secondary 160 MHz channel) to the STA 2 for responding to the first wireless frame.

[0155] Optionally, for each STA 102, in the case that the AP 101 allocates a communication channel to the STA 102 and also allocates a channel for the STA 102 to respond to the first wireless frame, the second identification information and the third identification information corresponding to the STA 102 can be carried in the same user info field in the first wireless frame; in other words, in the first wireless frame, there is a user info field corresponding to each STA 102 to indicate the channel resource information allocated by the AP 101 to the STA 102.

[0156] Optionally, in the case that the AP 101 allocates a channel for the STA 102 to respond to the first wireless frame, the response information of the corresponding STA 102 to the first wireless frame can be received through the channel.

[0157] Optionally, the first wireless frame can further include a padding field, and the fourth identification information can be carried in the padding field.

[0158] Optionally, the channel switching delay information of the AP 101 can include the time length required for the AP 101 to perform channel switching, for example, can be 16us (microsecond), 32us, etc.

[0159] Optionally, the channel switching delay information of the AP 101 can be determined according to the transmission mode of the first wireless frame. Optionally, if the first wireless frame is a broadcast message frame or a groupcast message frame, the channel switching delay information of the AP 101 in the padding field can be the maximum value in the channel switching delay information of all STAs 102 associated with the AP 101. For example, in the case that the channel switching delay information of STA1 is 16us, the channel switching delay information of STA2 is 16us, and the channel switching delay information of STA3 is 32us, the channel switching delay information of the AP 101 can include 32us. Optionally, if the first wireless frame is a unicast message frame, assuming that the first wireless frame is a wireless frame sent by the AP 101 to STA1, the channel switching delay information of the AP 101 in the padding field is the padding information value carried by the eighth identification information in the second wireless frame sent by STA1 in the association process between STA1 and the AP 101.

[0160] Step 202: The AP 101 sends the first wireless frame to the STA 102.

[0161] Step 203: The STA 102 receives the first wireless frame sent by the AP 101.

[0162] In some embodiments, as shown in FIG. 3, before step 201, the method further includes:

[0163] In step 301, the STA 102 determines a second wireless frame in the process of establishing initial association with the AP 101; wherein the second wireless frame comprises at least one of fifth identification information, sixth identification information and seventh identification information; the fifth identification information is used to identify the maximum operating bandwidth supported by the STA 102; the sixth identification information is used to identify the support capability information of the STA 102 for dynamic switching channels; and the seventh identification information is used to identify the support capability information of the STA 102 for receiving a data frame based on a large bandwidth.

[0164] The large bandwidth is greater than the maximum operating bandwidth; and the maximum operating bandwidth is greater than or equal to the bandwidth identified by the fourth identification information corresponding to the STA 102.

[0165] Optionally, the second wireless frame can include, but is not limited to, a Probe Request frame, an Association Request frame and a Reassociation Request frame.

[0166] In some embodiments, the sixth identification information can be 1 bit, and the support capability information of the STA 102 for dynamic switching channels can be identified by the parameter value of the bit. For example, in the case where the parameter value of the bit is set to 1, it is identified that the STA 102 supports dynamic switching channels; and in the case where the parameter value of the bit is set to 0, it is identified that the STA 102 does not support dynamic switching channels.

[0167] In the embodiments of the present disclosure, after the AP 101 allocates channel resource information to at least two STAs 102 respectively, if the communication channel corresponding to a certain STA 102 is busy, in the case where the STA 102 supports dynamic channel switching, the STA 102 can switch to other idle channels of the AP 101 to perform communication.

[0168] Referring to FIG. 5, in the process of channel contention on the channel, if the primary channel is in an OBSS busy state (OBSS interference), as shown in the T1 time period and the T2 time period in FIG. 5, for example, occupied by other devices in the same OBSS as the WLAN, the other devices send a physical layer protocol data unit (PPDU) on the primary channel, then the primary channel is in the OBSS busy state. If the primary channel is in the OBSS busy state, in order to be able to fully utilize the channel resources, the secondary channel communication can be switched to, so as to improve the throughput of the communication system and realize the maximization of utilization of the channel resources. For example, in FIG. 5, the 20MHz secondary channel communication is switched to in the T1 time period, or the 40MHz secondary channel communication is switched to in the T2 time period.

[0169] If the primary channel is idle, as shown in the T3 time period in FIG. 5, the AP and the STA can transmit PPDUs to each other.

[0170] In addition, when the primary channel is busy (the secondary channel is idle), the primary and secondary channels can be aggregated to communicate to improve the throughput of the system; as an example, as shown in FIG. 5, during the transmission of each frame, the primary channel and at least one secondary channel can be aggregated to transmit.

[0171] Optionally, the large-bandwidth-based data frame can include a large-bandwidth-based PPDU (Physical Layer Protocol (PHY) Data Unit).

[0172] In some embodiments, the seventh identification information can be 1 bit, and the parameter value of the bit can represent the support capability information of the STA 102 for receiving the large-bandwidth-based data frame. For example, in the case where the parameter value of the bit is set to 1, it is identified that the STA 102 supports receiving the large-bandwidth-based data frame; in the case where the parameter value of the bit is set to 0, it is identified that the STA 102 does not support receiving the large-bandwidth-based data frame.

[0173] As an example, in the case where the STA 102 supports receiving the large-bandwidth-based PPDU, if the maximum operating bandwidth supported by the STA 102 is 80 MHz, the STA 102 supports receiving a 320 MHz PPDU; for another example, if the maximum operating bandwidth supported by the STA 102 is 40 MHz, the STA 102 supports receiving a 160 MHz PPDU.

[0174] Optionally, in the embodiments of the present disclosure, the second wireless frame further includes eighth identification information, and the eighth identification information is used to identify time delay information of the STA 102 performing dynamic switching of channels.

[0175] Optionally, the second wireless frame can further include a padding field, and the eighth identification information can be carried in the padding field.

[0176] Optionally, the time delay information of the STA 102 performing channel switching can include a time length required by the STA 102 for performing channel switching, for example, can be 16 us, 32 us, etc.

[0177] Step 302: The STA 102 sends a second wireless frame to the AP 101.

[0178] In some embodiments, as shown in FIG. 3, after step 203, the method further includes:

[0179] Step 303, the STA 102 responds to the first wireless frame.

[0180] Optionally, in the case that the fourth identification information corresponding to the STA 102 is included in the first wireless frame, the STA 102 responds to the first wireless frame in the channel identified by the fourth identification information.

[0181] Or

[0182] In the case that the third identification information corresponding to the STA 102 is included in the first wireless frame, and the fourth identification information corresponding to the STA 102 is not included in the first wireless frame, the STA 102 responds to the first wireless frame in the channel identified by the third identification information.

[0183] Optionally, the STA 102 can respond to the first wireless frame by sending a CTS (clear to send) frame to the STA 102.

[0184] Optionally, in the case that the AP 101 allocates a dedicated channel for the STA 102 to respond to the first wireless frame (i.e., the fourth identification information is included in the first wireless frame), the STA 102 can respond to the first wireless frame in the channel identified by the fourth identification information; in the case that the AP 101 only allocates a communication channel to the STA 102, and does not allocate a dedicated channel for the STA 102 to respond to the first wireless frame (i.e., the third identification information is included in the first wireless frame, and the fourth identification information is not included in the first wireless frame), the STA 102 can respond to the first wireless frame in the channel identified by the third identification information.

[0185] Step 304, after the AP 101 receives the response information of the STA 102 to the first wireless frame, the AP 101 communicates with the STA 102 corresponding to the third identification information in the channel identified by the third identification information.

[0186] Optionally, in the process of the AP 101 communicating with the STA 102, the AP 101 can send a DL MIMO PPDU (down-link MIMO PPDU, downlink MIMO physical layer protocol data unit; MIMO means Multiple-Input Multiple-Output, multiple-input multiple-output, abbreviated as multiple-input multiple-output) to the STA 102, and the STA 102 can send an UL TB PPDU (up-link Trigger-Based PPDU, uplink trigger-based physical layer protocol data unit) to the AP 101.

[0187] In the embodiments of the present disclosure, the STA 102 involved in steps 203 and 301 to 304 can be any one of the STAs 102 associated with the AP 101.
