Background technique

Currently, technologies based on wireless connections, such as mobile hotspots (wireless fidelity, WiFi), Bluetooth (bluetooth, BT), and zigbee, all manage communications between devices independently within the scope of their respective protocol channels. However, the switching speed between the above protocol channels is slow and the process is complicated, and the data transmitted in each protocol channel is completely independent.

The terminal equipment involved in this application includes equipment that provides voice and/or data signal connectivity to users. Specifically, it includes equipment that provides voice to users, or includes equipment that provides data signal connectivity to users, or includes providing users with Equipment for voice and data signal connectivity. This may include, for example, a handheld device with wireless connectivity, or a processing device connected to a wireless modem. The terminal equipment may include user equipment (user equipment, UE), wireless terminal equipment, mobile terminal equipment, device-to-device communication (device-to-device, D2D) terminal equipment, vehicle to everything (V2X) terminal equipment , machine-to-machine/machine-type communications (M2M/MTC) terminal equipment, Internet of things (IoT) terminal equipment, subscriber unit (subscriber unit), subscriber station (subscriber station), mobile station, remote station, access point (AP), remote terminal equipment (remote terminal), access terminal equipment (access terminal), user terminal equipment (user terminal) ), user agent, or user device, satellite, drone, balloon or aircraft, etc. For example, this may include a mobile phone (or "cellular" phone), a computer with a mobile terminal device, a portable, pocket-sized, handheld, computer-built-in mobile device, etc. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants, PDA), and other equipment.

Currently, wireless-based connections such as WiFi, BT, and zigbee technologies independently manage communications between devices within the scope of their respective protocol channels. As shown in Figure 2, a solution for mixed use of BT and WiFi is shown. Both the terminal device 201 and the terminal device 202 have two channels running the WiFi protocol and the BT protocol. In order to reduce the power consumption of the terminal device 201 and the terminal device 202, the terminal device 201 and the terminal device 202 will use BT transmission when the amount of data is low, such as when transmitting notification messages, transmitting health data or telephone voice. In cases where the amount of data is large, such as firmware updates, application downloads or file transfers, WiFi transmission is used to reduce user waiting time.

Among them, the switching process of Bluetooth and WiFi is shown in Figure 3. Among them, the terminal device 201 and the terminal device 202 can turn on Bluetooth and perform Bluetooth broadcast scanning. In this way, the terminal device 201 and the terminal device 202 discover each other and perform Bluetooth links. The terminal device 201 and the terminal device 202 can transmit service data with a low data volume through Bluetooth. If the terminal device 201 and/or the terminal device 202 determine that there is no need to transmit high-volume service data, the terminal device 201 and the terminal device 202 can determine whether the Bluetooth is disconnected. If the Bluetooth is disconnected, the Bluetooth broadcast scan can be re-executed. If the Bluetooth If there is no disconnection, you can continue to transmit business data with a low data volume through Bluetooth. If the terminal device 201 and/or the terminal device 202 determine that high-volume service data needs to be transmitted, the terminal device 201 and the terminal device 202 may exchange WiFi distribution network information through Bluetooth. The terminal device 201 and the terminal device 202 can turn on WiFi and perform WiFi links through the exchanged WiFi distribution network information. The terminal device 201 and the terminal device 202 can transmit high-volume service data through WiFi.

If Bluetooth is not disconnected, service data with a low data volume can continue to be transmitted through Bluetooth.

Referring to Figure 4, a file sharing solution is shown. In the file sharing technology shown in Figure 4, the terminal device 401 and the terminal device 402 can discover each other based on Bluetooth scanning, and after exchanging WiFi network configuration information through Bluetooth connection, a WiFi P2P link is established to transfer files and share.

Among them, the switching process of Bluetooth and WiFi is shown in Figure 5. Among them, the terminal device 401 can discover the terminal device 402 through Bluetooth scanning, and perform a Bluetooth link with the terminal device 402. The terminal device 401 can exchange WiFi distribution network information through Bluetooth and then disconnect Bluetooth. The terminal device 401 and the terminal device 402 can perform a WiFi point-to-peer (peer to peer, P2P) link through WiFi distribution network information. Terminal device 401 and terminal device 402 can share and transfer files through WiFi P2P links. The terminal device 401 and the terminal device 402 can disconnect WiFi after the file sharing ends.

However, in the above-mentioned Bluetooth and WiFi switching method, the Bluetooth and WiFi switching speed is slow and the process is complicated, and there is no way to achieve data frame level switching. Moreover, the data transmitted by Bluetooth and WiFi are completely independent, and data frames cannot be transmitted in fragments on different channels. Not only that, the mutual interference between Bluetooth and WiFi can only be arbitrated and switched on a single device, and the interference problem of multiple devices cannot be coordinated in a multi-device network.

In view of this, embodiments of the present application provide a data transmission method to schedule multiple wireless protocol channels to meet the requirements of communication scenarios. In this method, the first device may schedule the second device to send or receive data based on a different protocol, such as a second protocol, a third protocol, etc., based on a protocol supported by both the first device and the second device, such as the first protocol. At least two of the above-mentioned first agreement, second agreement and third agreement are different.

In order to facilitate understanding of the technical solutions provided by the embodiments of the present application, the first protocol involved in the embodiments of the present application is described below.

In one possible case, the first protocol may be a prior art protocol or an evolution of a prior art protocol. For example, the first protocol may be a WiFi protocol, a Bluetooth protocol, a zigbee protocol, or the like. Optionally, the first protocol may be a protocol capable of controlling time slots, such as the Bluetooth protocol. Since the signaling frame of the Bluetooth protocol can indicate the time slot for transmitting data, the first device can schedule the second device to transmit data through the Bluetooth protocol.

In another possible situation, the first protocol may be a new protocol, and the first protocol may support networking between devices. For example, the first device and the second device may form a device group, and the first device in the device group may The second device is scheduled to perform data transmission.

The first protocol will be described below with reference to the accompanying drawings. Refer to FIG. 6 , which is an exemplary flow chart of networking between the first device and the second device in this embodiment of the present application, which may include the following operations.

S602: The second device sends an access request frame to the first device.

Correspondingly, the first device may receive the access request frame from the second device.

In one example, the second frame may carry the resource configuration information of the first frame. For example, the second frame may carry the time-frequency resource information of the first frame. Optionally, the second frame may also carry period information of the first frame. The first frame can be understood as a frame used by the first device in this article to schedule the second device to communicate on different protocols, which will be introduced later.

In a possible implementation, the second device can determine whether to access the first device according to the resource configuration information of the first frame. That is to say, the second device can determine whether to form a network with the first device. For example, the second device may determine the time domain resources and frequency domain resources occupied by the first frame based on the resource configuration information of the first frame. In this way, the second device can determine whether the second device can receive the first frame based on the time domain resources and frequency domain resources, or determine whether the second device has data transmission on the time domain resources and frequency domain resources. When the second device is able to receive the first frame, or the second device has no data transmission on the time domain resource and frequency domain resource, the second device may determine to access the first device, and perform S602.

It can be understood that the embodiment of the present application does not limit the way in which the second device determines whether to access the first device. In addition to the above implementation, the second device can also determine whether to access the first device through other methods. For example, the second device can access the first device when the distance from the first device is less than or equal to a certain threshold.

Optionally, in order to reduce the resources occupied by the second frame, the first device broadcasts the second frame multiple times in a short period of time, so that more devices can discover the first device. The second frame can indicate the third frame. The time-frequency resource information of the first frame is carried in the third frame. For example, the time unit offset between the second frame and the third frame may be specified by the protocol or carried by the second frame. For another example, the second frame may indicate information about the time-frequency resources occupied by the third frame. It can be understood that the embodiment of the present application does not limit the implementation in which the second frame indicates the time-frequency resource information of the third frame.

S603: The first device sends an access response frame to the second device.

Correspondingly, the second device receives the access response frame from the first device.

Wherein, when the second device receives an access request frame from the first device, the second device may send an access response frame to the first device. The access response frame may be used to instruct the second device to access the first device, or the access response frame may indicate that the network between the first device and the second device is successful. Optionally, the access response frame may carry the resource configuration information of the first frame. For example, when the second frame or the third frame does not carry the resource configuration information of the first frame, the access response frame may carry the resource configuration information of the first frame.

It should be noted that the devices mentioned in this article, such as the first device, the second device and the third device all support communication based on the first protocol. It can be understood that the method for the third device to access the third device may be as shown in FIG. 6 , and will not be described in detail below. In this article, the second device and the third device are connected to the first device as an example for explanation.

The data transmission method provided by the embodiment of the present application is introduced below with reference to the accompanying drawings. Referring to Figure 7, an exemplary flow chart of a data transmission method provided by an embodiment of the present application may include the following operations.

S701: The first device sends the first frame to the second device based on the first protocol.

Correspondingly, the second device may receive the first frame from the first device. For example, a first device may broadcast a first frame, and a second device may receive the broadcasted first frame. For another example, the first device may multicast the first frame, and the second device may receive the multicast first frame. For another example, the first device may unicast the first frame to the second device.

Wherein, the first frame may include a beacon frame. In one example, the beacon frame may be used to synchronize the time of the first device and the second device. In other words, the beacon frame may be used to synchronize the time unit in which the first device supports the channel of each protocol and the time unit in which the second device supports the channel of each protocol. For example, based on the beacon frame, the second device synchronizes with the first device at a time unit that supports the channel of the first protocol and at a time unit that supports the channel of the second protocol with the first device. For another example, based on the beacon frame, the first device synchronizes the time unit of the channel supporting the first protocol with the time unit of the second device supporting the channel of the first protocol.

It can be understood that the above channels can be understood as frequency domain resources, such as carriers or subcarriers. Alternatively, a channel can be understood as a time-frequency resource, such as a resource block.

Herein, the first frame may satisfy the first protocol. For example, when the first protocol is the Bluetooth protocol, the first frame may be a frame in the Bluetooth protocol, such as a control frame, a signaling frame, etc. For another example, when the first protocol is a new protocol, the first frame may be a frame that satisfies the new protocol.

In the above, the first frame may also include a first signaling frame. In the case where the first protocol is a new protocol, the first frame may use physical layer control information A7 or physical layer control information B4. Referring to Figure 8, the data portion of the first frame includes a data packet header and a payload. The data packet header may include a signaling number. The signaling number may be the number corresponding to the signaling frame included in the first frame. The payload portion may include a beacon frame, as well as one or more signaling structures. It can be understood that a signaling structure can be understood as a signaling frame. Each signaling structure satisfies the corresponding protocol.

For example, the first frame contains the signaling structure of the first signaling frame. The first signaling frame instructs the second device to send data based on the Bluetooth protocol. Then the signaling structure of the first signaling frame needs to meet the requirements of the Bluetooth protocol. , for example, the signaling structure of the first signaling frame may be the signaling structure of the Bluetooth protocol.

Optionally, as shown in Figure 8, the data packet header may also contain a fragmentation indication. The segment indication is used to indicate the starting bit of each signaling frame. Alternatively, the segmentation indication may be used to indicate the end bit of the beacon frame and the end bit of each signaling frame.

S702: Based on the beacon frame, the first device synchronizes the time unit of the channel supporting the first protocol with the time unit of the channel of the second device supporting the first protocol.

Similarly, based on the beacon frame, the second device synchronizes with the first device on the time unit of the channel that supports the first protocol and on the time unit of the channel that supports the second protocol that the first device supports the channel of the first protocol.

In a possible implementation, the first signaling frame may be used to instruct the second device to receive or send the first data based on the second protocol. The second protocol may be the same as or different from the first protocol. For example, the first protocol is a Bluetooth protocol, and the second protocol can also be a Bluetooth protocol. For another example, the first protocol is a new protocol, and the second protocol may be a WiFi protocol. It can be understood that the second device supports communication based on the second protocol.

S703: The second device receives or sends the first data based on the second protocol.

In a possible situation, based on the first signaling frame, the second device may send the first data based on the second protocol. For example, the second device may send the first data to the first device based on the second protocol, and the first device supports communication based on the second protocol. For another example, the second device may send the first data to the third device based on the second protocol, and the third device may support communication based on the second protocol.

In another possible situation, based on the first signaling frame, the second device may receive the first data based on the second protocol. For example, the second device may receive first data from the first device based on the second protocol, and the first device supports communication based on the second protocol. For another example, the second device may receive the first data from the third device based on the second protocol, and the third device may support communication based on the second protocol.

Optionally, the first signaling frame may include an identifier of the second protocol, or may include an identifier of a channel that supports communication of the second protocol, to indicate that the second device receives or sends the first data based on the second protocol. Optionally, the first signaling frame may also include indication information of time-frequency resources of the first data. In this way, the second device can receive or send the first data on the time-frequency resource indicated by the first signaling frame based on the second protocol indicated by the first signaling frame.

In a possible implementation, the first signaling frame may indicate at least one of data transmission rate, uplink and downlink, and content. For example, assume that the first signaling frame carries the identifier of the second protocol and indicates that the first data is downlink. That is to say, the first signaling frame instructs the second device to receive the first data based on the second protocol. For another example, assume that the first signaling frame carries the identifier of the second protocol and indicates that the first data is uplink and the transmission rate of the first data is Z kb/s. That is to say, the first signaling frame indicates that the second device is based on The second protocol sends the first data, and the transmission rate of the first data is Z kb/s. For another example, the first signaling frame carries the identifier of the second protocol, carries indication information of time-frequency resources, and indicates content A. That is to say, the first signaling frame instructs the second device to receive or send the first data with content A on the time-frequency resource indicated by the indication information based on the second protocol.

In a possible situation, the first frame may also include a second signaling frame. The second signaling frame may instruct the second device to receive or send the second data based on the third protocol. The second device supports communications based on the third protocol.

Understandably, the second agreement is different from the third agreement. That is to say, the first device can schedule the second device to perform data transmission based on different protocols, such as the second protocol and the third protocol.

It should be noted that since the second protocol is different from the third protocol, the signaling structure of the first signaling frame is different from the signaling structure of the second signaling frame. Optionally, the information type indicated by the second signaling frame may be the same as the information type indicated by the first signaling frame. For example, the second signaling frame may also indicate at least one of transmission data, uplink and downlink data, and content. For example, the second signaling frame may indicate the identity of the third protocol or the identity of a channel that supports the third protocol. Reference may be made to the foregoing implementation of the first signaling frame, which will not be described again here.

In a possible situation, based on the second signaling frame, the second device can send the second data based on the third protocol. For example, the second device may send second data to the first device based on a third protocol, and the first device supports communication based on the third protocol. For another example, the second device may send the second data to the third device based on the third protocol, and the third device may support communication based on the third protocol.

In another possible situation, based on the second signaling frame, the second device may receive the second data based on the third protocol. For example, the second device may receive second data from the first device based on a third protocol, and the first device supports communication based on the third protocol. For another example, the second device may receive the second data from the third device based on the third protocol, and the third device may support communication based on the third protocol.

In a possible implementation manner, the second protocol may be determined based on at least one of capability information of the second device and information on channels of the second device supporting each protocol. Wherein, the capability information of the second device may indicate a protocol supported by the second device. The above-mentioned information about the channels supporting each protocol may include at least one of interference information, busy information, transmission rate and power consumption information.

In a possible situation, the second device may send capability information and information about channels supporting each protocol to the first device. It can be understood that the second device can send capability information and channel information supporting each protocol to the first device based on the first protocol.

In one example, the second protocol may be determined based on capability information of the second device. For example, the capability information of the second device may indicate that the second device supports using a channel running the WiFi protocol, then the first channel may be a channel running the WiFi protocol.

In another example, the second protocol may be determined based on information about channels of the second device that support each protocol. For example, the channel that supports the second protocol may be a channel with less interference or an idle channel among the channels of the second device that supports each protocol.

For example, assume that the second device supports communication based on the Bluetooth protocol, supports communication based on the WiFi protocol, and supports communication based on the zigbee protocol. When the channel supporting communication based on the Bluetooth protocol and the channel supporting communication based on the zigbee protocol are interfered with or busy, the first device may instruct the second device to receive or send data based on the Wifi protocol through the first signaling frame.

For another example, the first device may select a channel whose transmission rate matches the data requirement from channels that support each protocol. For example, assume that the second device supports communication based on the Bluetooth protocol, supports communication based on the WiFi protocol, and supports communication based on the zigbee protocol. In the case where the transmission rate of the channel supporting communication based on the WiFi protocol and the transmission rate of the non-channel supporting communication based on the zigbee protocol are low and cannot meet the data transmission rate requirement, the first device may indicate the first signaling frame through the first signaling frame. The second device receives or sends data based on the Bluetooth protocol.

Understandably, the need for data is related to the communication scenario. For example, in a high-speed transmission scenario, the data transmission rate is required to be no less than 172 kb/s. Therefore, in a high-speed transmission scenario, the first device can instruct the second device to receive or send data through a channel that meets the data requirements.

For another example, the first device may determine the second protocol based on the power consumption of the channel. For example, assume that the second device supports communication based on the Bluetooth protocol, supports communication based on the WiFi protocol, and supports communication based on the zigbee protocol. Among them, it is assumed that the channel that supports communication based on the WiFi protocol has the highest power consumption, the channel that supports communication based on the zigbee protocol has the second highest power consumption, and the channel A that supports communication based on the Bluetooth protocol has the lowest power consumption. The first device may instruct the second device to receive or send data based on the Bluetooth protocol when the second device requires low energy consumption.

Optionally, the first device may send the first frame to the third device based on the first protocol. For example, a first device may broadcast a first frame, and a third device may receive the broadcast first frame. For another example, the first device may multicast the first frame, and the third device may receive the first multicast frame. For another example, the first device may unicast the first frame to the third device.

Similarly, based on the beacon frame, the third device synchronizes with the first device on the time unit of the channel that supports the first protocol and the time unit of the channel that supports the fourth protocol that the first device supports the channel of the first protocol.

In a possible implementation, the above first frame may also include a third signaling frame. The third signaling frame may instruct the third device to receive or send third data based on the fourth protocol. The fourth protocol and the first protocol may be the same or different. Similarly, the fourth agreement and the second agreement may be the same or different, and the fourth agreement and the third agreement may be the same or different. That is to say, the first device can schedule different devices for data transmission.

It should be noted that the signaling structure of the third signaling frame can satisfy the third protocol. Optionally, the information type indicated by the third signaling frame may be the same as the information type indicated by the first signaling frame. For example, the third signaling frame may also indicate at least one of transmission data, uplink and downlink data, and content. For example, the third signaling frame may indicate the identity of the fourth protocol or the identity of a channel that supports the fourth protocol. Reference may be made to the foregoing implementation of the first signaling frame, which will not be described again here.

In a possible situation, based on the third signaling frame, the third device may send third data based on the fourth protocol. For example, the third device may send third data to the first device based on the fourth protocol, and the first device supports communication based on the fourth protocol. For another example, the third device may send third data to the second device based on the fourth protocol, and the second device may support communication based on the fourth protocol.

In another possible situation, based on the third signaling frame, the third device may receive third data based on the fourth protocol. For example, the third device may receive third data from the first device based on a fourth protocol, and the first device supports communication based on the fourth protocol. For another example, the third device may receive third data from the second device based on the fourth protocol, and the second device may support communication based on the fourth protocol.

Since the first device can schedule multiple devices for data transmission, in order to distinguish which device the signaling frame is intended for, in one example, the signaling frame can carry the identifier of the device. For example, the first signaling frame may carry the identity of the second device, the second signaling frame may carry the identity of the second device, and the third signaling frame may carry the identity of the third device. In this way, the device identification of the device can be used to determine which device the signaling frame corresponds to.

In another example, the above beacon frame may indicate relevant information of the signaling frame. Therefore, the device corresponding to the signaling frame may be indicated by the beacon frame. For example, the beacon frame may indicate information about the time for sending the signaling frame, and information about the device corresponding to the time for sending the signaling frame.

For example, the beacon frame may include time slot numbers and the identification of the device corresponding to each time slot number. It can be understood that the time slot corresponding to each of the above time slot numbers can be used to send signaling frames, such as the first signaling frame or the second signaling frame. In this way, the time slot number corresponding to the own identification can be determined based on the corresponding relationship between the time slot number in the beacon frame and the identification of the device. Therefore, the second device can receive the first signaling frame and the second signaling frame on the time slot number corresponding to the identity of the second device, and the third device can receive the first signaling frame and the second signaling frame on the time slot number corresponding to the identity of the third device. The third signaling frame.

Optionally, the beacon frame may also indicate information about the time for sending data, such as first data, second data or third data. It should be noted that the time used for sending data can be understood as that the device can send data at this time, but not that there must be data transmission and reception at this time. Scheduling based on the first frame can schedule communication on unreachable channels for the same device, and can also schedule communication on different devices on the same channel.

Based on the embodiment shown in Figure 7, the first device can schedule the second device to perform data transmission based on different protocols through the first frame, or can schedule different devices, such as the second device and the third device, to perform data transmission based on the same or different protocols. The protocol for data transmission can meet the needs of various scenarios. In this solution, since data transmission is scheduled through the first frame, interference to data transmission can be reduced and channels of different protocols can be fully utilized for communication.

Refer to FIG. 9 , which is one of the schematic diagrams of the first frame according to an embodiment of the present application. As can be seen in Figure 9, the first frame may include at least one beacon frame, 1 to n signaling frames and 0 to m data frames, n is an integer greater than or equal to 1, and m is an integer greater than or equal to 0. . The beacon frame may be used to synchronize time between the first device and the edge node device, such as the second device and the third device, or to synchronize time units of channels that support various protocols. The signaling frame may instruct a device, such as a second device, to receive or send data based on a certain protocol, such as a second protocol. A data frame can carry data, such as first data received or sent by a second device.

It can be understood that the first device may instruct the second device to transmit data with the same device or a different device through the first frame. The first device may instruct the second device to transmit data with the same device or different devices in different time units. Optionally, the first device may instruct the second device to transmit data based on the same protocol or based on different protocols. Below, we will introduce each situation through different situations.

Below, the data transmission method provided by the embodiment of the present application is introduced through Figure 11. In the embodiment shown in FIG. 11 , the first protocol is the new protocol, the second protocol is the Bluetooth protocol, and the third protocol is the WiFi protocol. Refer to Figure 11, which is a schematic diagram of an exemplary scenario of a data transmission method provided by an embodiment of the present application. In Figure 11, device A is the central device, and device B, device C, and device D are all edge node devices of device A. Among them, device A, device B, device C and device D all support communication based on the new protocol. Device A also supports communication based on Bluetooth protocol and WiFi protocol; device B also supports communication based on Bluetooth protocol; device C also supports communication based on Bluetooth protocol; device D also supports communication based on WiFi protocol.

In Figure 11, device A wants to schedule device B, device C, and device D to transmit data. Therefore, device A can send the first frame. For example, device A may broadcast the first frame, and device B, device C, and device D may receive the broadcasted first frame. The first frame may include a beacon frame. Based on the beacon frame, device A, device B, device C and device D can synchronize the time units of channels supporting communication of each protocol.

The first frame may also include signaling frame #1, signaling frame #2 and signaling frame #3. Signaling frame #1 instructs device B to receive data from device A based on the Bluetooth protocol. For example, the signaling frame #1 may include the identifier of the Bluetooth protocol and the indication information of the first time-frequency resource. Optionally, the signaling frame #1 may also indicate that the data corresponding to the first time-frequency resource is downlink. In this way, device B can receive data frame #1 from device A on the first time-frequency resource based on the new protocol. Signaling frame #1 also instructs device B to receive data from device A based on the Bluetooth protocol. For example, the signaling frame #1 may also include an identifier of the Bluetooth protocol and indication information of the second time-frequency resource. Optionally, the signaling frame #1 may also indicate that the data corresponding to the second time-frequency resource is downlink. In this way, device B can receive data frame #3 from device B on the second time-frequency resource based on the Bluetooth protocol. Signaling frame #1 also instructs device B to send data to device C based on the Bluetooth protocol. For example, the signaling frame #1 may also include an identifier of the Bluetooth protocol and indication information of the third time-frequency resource. Optionally, the signaling frame #1 may also indicate that the data corresponding to the third time-frequency resource is uplink. In this way, device B can send data frame #5 to device C on the third time-frequency resource based on the Bluetooth protocol.

Signaling frame #2 instructs device C to receive data from device A based on the Bluetooth protocol. For example, signaling frame #2 may include an identifier of the Bluetooth protocol and indication information of the fourth time-frequency resource.

In this way, device C can receive data frame #5 from device B on the fifth time-frequency resource based on the Bluetooth protocol.

Signaling frame #3 instructs device D to send data to device A based on the WiFi protocol. For example, signaling frame #3 may include an identifier of the WiFi protocol and indication information of the sixth time-frequency resource. Optionally, the signaling frame #3 may also indicate that the data corresponding to the sixth time-frequency resource is uplink. In this way, device D can send data frame #4 to device A on the sixth time-frequency resource based on the WiFi protocol.

The communication device used to implement the above method in the embodiment of the present application will be introduced below with reference to the accompanying drawings. Therefore, the above content can be used in subsequent embodiments, and repeated content will not be described again.

The communication device 1200 can correspondingly implement the functions or steps implemented by the first device or the second device in each of the above method embodiments. The communication device may include a processing unit 1210 and a transceiver unit 1220. Optionally, a storage unit may also be included, which may be used to store instructions (code or programs) and/or data. The processing unit 1210 and the transceiver unit 1220 can be coupled with the storage unit. For example, the processing unit 1210 can read the instructions (code or program) and/or data in the storage unit to implement the corresponding method. Each of the above units can be set up independently or partially or fully integrated.

In some possible implementations, the communication device 1200 can correspondingly implement the behaviors and functions of the first device in the above method embodiment. For example, the communication device 1200 may be a first device, or may be a component (such as a chip or a circuit) used in the first device. The transceiver unit 1220 may be used to perform all receiving or sending operations performed by the first device in the embodiments shown in FIGS. 6 to 11 . For example, S602 in the embodiment shown in Figure 6, and/or other processes used to support the technology described herein; wherein, the processing unit 1210 is used to execute the first device in the embodiment shown in Figures 6 to 11 All operations performed except the transceiver operation, such as S601 in the embodiment shown in FIG. 6, and/or other processes used to support the technology described herein.

For example, the transceiver unit 1220 is configured to send the first frame to the second device based on the first protocol. The first device and the second device support communication based on the first protocol. The first frame includes a beacon frame and a first signaling frame. The first signaling frame instructs the second device to send or receive first data based on a second protocol. The first agreement is different from the second agreement. The second device also supports second device-based communications. The processing unit 1210 is configured to synchronize the time unit of the channel supporting the first protocol with the time unit of the channel of the second device supporting the first protocol based on the beacon frame.
