[0150] The first time information may include at least one of the following:

[0151] a time interval during which the first device transmits data in the first communication mode;

[0152] A time interval during which the first device performs data transmission in other communication manners.

[0153] For example, the first time information may include a time interval during which the first device transmits data in a Wi-Fi communication manner.

[0154] For example, the first time information may include a time interval during which the first device transmits data in a communication manner other than the Wi-Fi communication manner.

[0155] Among them, the first communication mode can be a Wi-Fi communication mode, and other communication modes can be one or more of a Bluetooth (BT) communication mode, a New Radio (NR) communication mode, a Long Term Evolution (Long Term Evolution) communication mode, an Ultra Wide Band (UWB) communication mode, or a Zigbee communication mode.

[0156] It should be noted that the above-mentioned communication modes other than the first communication mode are merely examples, and may specifically be any other wireless communication mode other than the Wi-Fi communication mode, which will not be described in detail here.

[0157] Step S22: The second device sends a control frame response frame in the first communication mode, where the control frame response frame is used to indicate a second communication parameter for transmitting a data frame in the first communication mode.

[0158] In some embodiments, after receiving the initial control frame, the second device may determine a control frame response frame and send the control frame response frame to the first device in the first communication manner.

[0159] The control frame response frame is used to indicate the second communication parameter for transmitting the data frame in the first communication mode.

[0160] The second communication parameter indicated by the control frame response frame is a communication parameter actually used by the first device to transmit data frames with the second device in the first communication mode after receiving the control frame response frame.

[0161] The second communication parameter indicated by the control frame response frame may be a second communication parameter determined by the second device according to the first communication parameter after receiving the initial control frame.

[0162] In some embodiments, the second communication parameter includes one or more of a spatial stream (SS) parameter, a bandwidth (Bandwidth) parameter, or a modulation and coding scheme (MCS) parameter.

[0163] The spatial stream parameters may include the number of spatial streams for sending data frames and the number of spatial streams for receiving data frames.

[0164] In some embodiments, when the second device sends the control frame response frame in the first communication mode, the second device sends the control frame response frame in the first communication mode under one spatial stream SS.

[0165] In some embodiments, when the second device supports multi-link communication under the first communication mode, the control frame response frame is also used to indicate the first communication link for transmitting the data frame.

[0166] As an example, the control frame response frame includes multiple second identification bits, each second identification bit corresponding to a different communication link. The identification value of the second identification bit corresponding to the first communication link is the third value, indicating that the second device instructs, through the control frame response frame, to transmit a data frame through the first communication link corresponding to the second identification bit.

[0167] In a case where the second device supports multi-link communication under the first communication mode, the second communication parameter indicated by the initial control frame is a communication parameter for transmitting the data frame through the first communication link.

[0168] In some embodiments, the parameter value of the second communication parameter indicated by the control frame response frame may be the same as or different from the parameter value of the first communication parameter.

[0169] When the second device performs data transmission in at least two communication modes including the first communication mode, a parameter value of the second communication parameter is different from a parameter value of the first communication parameter.

[0170] That is, if the second device is transmitting data in at least two communication modes including the first communication mode when sending the control frame response frame, the parameter value of the second communication parameter indicated by the control frame response frame is different from the parameter value of the first communication parameter.

[0171] In other words, when the parameter value of the second communication parameter is different from the parameter value of the first communication parameter, the control frame response frame is also used to indicate that the second device is transmitting data in at least two communication modes including the first communication mode when sending the control frame response frame.

[0172] The parameter value of the second communication parameter is different from the parameter value of the first communication parameter, and may be at least one of a spatial stream parameter, a bandwidth parameter, or a modulation and coding strategy parameter.

[0173] As an example, the parameter value of the bandwidth parameter in the first communication parameter is 160MHz, and the parameter value of the bandwidth parameter in the second communication parameter is 140MHz, indicating that the second device can transmit data frames in the first communication mode at a bandwidth of 140MHz, and there are other communication modes for data transmission at a bandwidth of 20MHz.

[0174] When the second device performs data transmission in the first communication manner, the parameter value of the second communication parameter is the same as the parameter value of the first communication parameter.

[0175] That is, if the second device performs data transmission only in the first communication mode when sending the control frame response frame, the second communication parameter indicated by the control frame response frame is different from the parameter value of the first communication parameter.

[0176] In other words, when the parameter value of the second communication parameter is the same as the parameter value of the first communication parameter, the control frame response frame is further used to indicate that the second device is performing data transmission in the first communication mode when sending the control frame response frame.

[0177] It should be noted that when the first device and the second device support multi-link communication under the first communication mode, the parameter value of the first communication parameter is the same as the parameter value of the second communication parameter. In essence, the parameter value of the communication parameter corresponding to the first communication link in the first communication parameter is the same as the parameter value of the second communication parameter, and the first communication link is the communication link for data transmission indicated by the second device through the control frame response frame.

[0178] In some embodiments, the initial control frame is further used to indicate second time information.

[0179] The second time information may include at least one of the following:

[0180] a time interval during which the second device transmits data in the first communication mode;

[0181] The time interval during which the second device performs data transmission in other communication modes.

[0182] For example, the second time information may include a time interval during which the second device transmits data in a Wi-Fi communication manner.

[0183] For example, the second time information may include a time interval during which the second device transmits data in a communication manner other than the Wi-Fi communication manner.

[0184] Among them, the first communication mode can be a Wi-Fi communication mode, and other communication modes can be one or more of a Bluetooth (BT) communication mode, a New Radio (NR) communication mode, a Long Term Evolution (Long Term Evolution) communication mode, an Ultra Wide Band (UWB) communication mode, or a Zigbee communication mode.

[0185] It should be noted that the above-mentioned communication modes other than the first communication mode are merely examples, and may specifically be any other wireless communication mode other than the Wi-Fi communication mode, which will not be described in detail here.

[0186] Step S23: The first device and the second device transmit data frames in the first communication mode according to the second communication parameters.

[0187] In some embodiments, after the first device receives the control frame response frame, the first device and the second device may transmit data frames in the first communication manner according to the second communication parameters.

[0188] As an example, the first device sends a data frame to the second device in a first communication mode (such as a Wi-Fi communication mode) according to the spatial stream parameter, the modulation and coding strategy parameter, and the bandwidth parameter in the second communication parameter.

[0189] In some embodiments, when the first device and the second device support multi-link communication in a first communication mode, the first device and the second device can transmit data frames in the first communication mode under the first communication link according to the second communication parameter. The first communication link is the communication link for transmitting the data frame indicated by the control frame response frame.

[0190] In some embodiments, when the control frame response frame also includes second time information, the first device and the second device can transmit data frames to the second device in the first communication mode within the time interval when the second device transmits data in the first communication mode according to the second communication parameters.

[0191] In some embodiments, before the first device sends an initial control frame in the first communication mode and the second device sends a control frame response frame in the first communication mode, the first device may send a first wireless frame to the second device in the first communication mode, and the second device may send a second wireless frame to the first device in the first communication mode.

[0192] Among them, the first wireless frame and the second wireless frame are used to establish an initial association between the first device and the second device, that is, the first wireless frame and the second wireless frame are wireless frames sent to each other during the process of establishing the initial association between the first device and the second device, and are not limited here.

[0193] As an example, the first device may be a STA, the second device may be an AP, the first radio frame may be an association request frame sent by the first device to the second device, and the second radio frame may be an association response frame sent by the second device to the first device.

[0194] As an example, the first device may be an AP, the second device may be an STA, the second radio frame may be an association request frame sent by the second device to the first device, and the first radio frame may be an association response frame sent by the first device to the second device.

[0195] Optionally, the first radio frame is used to indicate that the first device supports data transmission in at least two communication modes including the first communication mode.

[0196] That is, the first radio frame is used to indicate that the first device has the ability to coexist with other communication modes and the first communication mode.

[0197] Among them, the first wireless frame may include a third identification bit, and the third identification bit indicates through a third value that the first device supports data transmission in at least two communication modes including the first communication mode, that is, the third value indicates that the first device has the ability to coexist with the first communication mode and other communication modes.

[0198] Optionally, the first radio frame is used to indicate that the first device supports at least one of periodic data transmission or burst data transmission.

[0199] Among them, the first wireless frame may include a fourth identification bit and a fifth identification bit, the fourth identification bit indicates that the first device supports periodic data transmission through a fourth value, and the fifth identification bit indicates that the first device supports burst data transmission through a fifth value.

[0200] Optionally, the second radio frame is used to indicate that the second device supports data transmission in at least two communication modes including the first communication mode.

[0201] That is, the second radio frame is used to indicate that the second device has the ability to coexist with the first communication mode and other communication modes.

[0202] Among them, the second wireless frame may include a sixth identification bit, and the sixth identification bit indicates through a sixth value that the first device supports data transmission in at least two communication modes including the first communication mode, that is, the sixth value indicates that the second device has the ability to coexist with the first communication mode and other communication modes.

[0203] Optionally, the second radio frame is used to indicate that the second device supports at least one of periodic data transmission or burst data transmission.

[0204] Among them, the second wireless frame may include a seventh identification bit and an eighth identification bit, the seventh identification bit indicates that the second device supports periodic data transmission through a seventh value, and the eighth identification bit indicates that the second device supports burst data transmission through an eighth value.

[0207] Step S31: determining an initial control frame, where the initial control frame is used to indicate first communication parameters supported by a first device for transmitting a data frame in a first communication manner.

[0208] In some embodiments, the first communication mode may be a Wi-Fi communication mode, and the first device may send the initial control frame to the second device in the Wi-Fi communication mode.

[0209] In some embodiments, the initial control frame is used to indicate first communication parameters supported by the first device for transmitting data frames in a first communication manner.

[0214] In some embodiments, when the first device supports multi-link communication in the first communication mode, such as when the first device is an AP MLD or a Non-AP MLD supporting a Wi-Fi communication mode, the initial control frame includes at least one first identification bit.

[0215] Among them, each first identification bit corresponds to a different communication link.

[0216] Each first identification bit is used to indicate whether the first device supports data transmission in the corresponding communication link.

[0217] As an example, each first identification bit indicates through a first value that the first device supports data transmission in the first communication mode on the corresponding communication link, and each first identification bit indicates through a second value that the first device does not support data transmission in the first communication mode on the corresponding communication link.

[0218] In some embodiments, when the first device supports multi-link communication in the first communication mode, the first communication parameters indicated by the initial control frame include communication parameters supported by the first device for transmitting data frames in each communication link.

[0219] As an example, when the first device supports data transmission over at least one second communication link under the first communication mode, the first communication parameters indicated by the initial control frame include communication parameters supported by the first device for transmitting data frames under each second communication link.

[0220] The communication parameters for transmitting data frames under each communication link may also include one or more of the aforementioned spatial stream parameters, bandwidth parameters, or modulation and coding strategy parameters.

[0221] The parameter values ​​of communication parameters used to transmit data frames over any two communication links may be the same or different.

The parameter values ​​of bandwidth parameters used to transmit data frames over any two communication links may be the same or different. The parameter values ​​of modulation and coding strategy parameters used to transmit data frames over any two communication links may be the same or different.

[0222] In some embodiments, the initial control frame is further used to indicate the first time information.

[0223] The first time information may include at least one of the following:

[0224] a time interval during which the first device transmits data in the first communication mode;

[0225] A time interval during which the first device performs data transmission in other communication manners.

[0226] For example, the first time information may include a time interval during which the first device transmits data in a Wi-Fi communication manner.

[0227] For example, the first time information may include a time interval during which the first device transmits data in a communication manner other than the Wi-Fi communication manner.

[0229] It should be noted that the above-mentioned communication modes other than the first communication mode are merely examples, and may specifically be any other wireless communication mode other than the Wi-Fi communication mode, which will not be described in detail here.

[0230] Step S32: Send an initial control frame in the first communication mode.

[0231] After determining the initial control frame, the first device may send the initial control frame to the second device in the first communication manner.

For example, any one of steps S31 and S32 may be implemented as an independent embodiment, and any combination of any number of steps in steps S31 and S32 may be implemented as an independent embodiment, but the present disclosure is not limited thereto.

[0233] FIG4 is a second flow chart of a communication method according to an embodiment of the present disclosure. As shown in FIG4 , the method is executed by a first device and includes:

[0234] Step S41: determining an initial control frame, where the initial control frame is used to indicate first communication parameters supported by the first device for transmitting data frames in a first communication manner.

[0235] Step S42: Send an initial control frame in the first communication mode.

[0236] In some embodiments, the implementation of step S41-step S42 can refer to the implementation shown in step S31-step S32 in Figure 3, and will not be repeated here.

[0237] Step S43: receiving a control frame response frame in the first communication mode, where the control frame response frame is used to indicate a second communication parameter for transmitting a data frame in the first communication mode.

[0238] In some embodiments, the control frame response frame is sent by the second device to the first device in the first communication manner after the second device receives the initial control frame.

[0239] The control frame response frame is used to indicate the second communication parameter for transmitting the data frame in the first communication mode.

[0240] The second communication parameter indicated by the control frame response frame is a communication parameter actually used by the first device to transmit data frames with the second device in the first communication mode after receiving the control frame response frame.

[0241] The second communication parameter indicated by the control frame response frame may be a second communication parameter determined by the second device according to the first communication parameter after receiving the initial control frame.

[0242] In some embodiments, the second communication parameter includes one or more of a spatial stream (SS) parameter, a bandwidth (Bandwidth) parameter, or a modulation and coding scheme (MCS) parameter.

[0246] As an example, the control frame response frame includes multiple second identification bits, each second identification bit corresponding to a different communication link. The identification value of the second identification bit corresponding to the first communication link is the third value, indicating that the second device instructs, through the control frame response frame, to transmit a data frame through the first communication link corresponding to the second identification bit.

[0247] In a case where the second device supports multi-link communication under the first communication mode, the second communication parameter indicated by the initial control frame is a communication parameter for transmitting the data frame through the first communication link.

[0248] In some embodiments, the parameter value of the second communication parameter indicated by the control frame response frame may be the same as or different from the parameter value of the first communication parameter.

[0249] When the second device performs data transmission in at least two communication modes including the first communication mode, a parameter value of the second communication parameter is different from a parameter value of the first communication parameter.

[0250] That is, if the second device is transmitting data in at least two communication modes including the first communication mode when sending the control frame response frame, the parameter value of the second communication parameter indicated by the control frame response frame is different from the parameter value of the first communication parameter.

[0251] In other words, when the parameter value of the second communication parameter is different from the parameter value of the first communication parameter, the control frame response frame is also used to indicate that the second device is transmitting data in at least two communication modes including the first communication mode when sending the control frame response frame.

[0252] The parameter value of the second communication parameter is different from the parameter value of the first communication parameter, and may be at least one of a spatial stream parameter, a bandwidth parameter, or a modulation and coding strategy parameter.

[0253] As an example, the parameter value of the bandwidth parameter in the first communication parameter is 160MHz, and the parameter value of the bandwidth parameter in the second communication parameter is 140MHz, indicating that the second device can transmit data frames in the first communication mode at a bandwidth of 140MHz, and there are other communication modes for data transmission at a bandwidth of 20MHz.

[0254] When the second device performs data transmission in the first communication manner, the parameter value of the second communication parameter is the same as the parameter value of the first communication parameter.

[0255] That is, if the second device performs data transmission only in the first communication mode when sending the control frame response frame, the second communication parameter indicated by the control frame response frame is different from the parameter value of the first communication parameter.

[0256] In other words, when the parameter value of the second communication parameter is the same as the parameter value of the first communication parameter, the control frame response frame is further used to indicate that the second device is performing data transmission in the first communication mode when sending the control frame response frame.

[0257] It should be noted that when the first device and the second device support multi-link communication under the first communication mode, the parameter value of the first communication parameter is the same as the parameter value of the second communication parameter. In essence, the parameter value of the communication parameter corresponding to the first communication link in the first communication parameter is the same as the parameter value of the second communication parameter, and the first communication link is the communication link for data transmission indicated by the second device through the control frame response frame.

[0258] In some embodiments, the initial control frame is further used to indicate second time information.

[0260] a time interval during which the second device transmits data in the first communication mode;

[0261] The time interval during which the second device performs data transmission in other communication modes.

[0262] For example, the second time information may include a time interval during which the second device transmits data in a Wi-Fi communication manner.

[0312] In some embodiments, the implementation of step S61 may refer to the implementation shown in step S51 in FIG5 , and will not be described in detail here.

[0313] Step S62: Send a control frame response frame in the first communication mode, where the control frame response frame is used to indicate a second communication parameter for transmitting a data frame in the first communication mode.

[0314] In some embodiments, after receiving the initial control frame, the second device may determine a control frame response frame and send the control frame response frame to the first device in the first communication manner.

[0315] The control frame response frame is used to indicate the second communication parameter for transmitting the data frame in the first communication mode.

[0316] The second communication parameter indicated by the control frame response frame is a communication parameter actually used by the first device to transmit data frames with the second device in the first communication mode after receiving the control frame response frame.

[0317] The second communication parameter indicated by the control frame response frame may be a second communication parameter determined by the second device according to the first communication parameter after receiving the initial control frame.

[0318] In some embodiments, the second communication parameter includes one or more of a spatial stream (SS) parameter, a bandwidth (Bandwidth) parameter, or a modulation and coding scheme (MCS) parameter.

[0319] The spatial stream parameters may include the number of spatial streams for sending data frames and the number of spatial streams for receiving data frames.

[0320] In some embodiments, when the second device sends the control frame response frame in the first communication mode, the second device sends the control frame response frame in the first communication mode under one spatial stream SS.

[0321] In some embodiments, when the second device supports multi-link communication under the first communication mode, the control frame response frame is also used to indicate the first communication link for transmitting the data frame.

[0322] As an example, the control frame response frame includes multiple second identification bits, each second identification bit corresponding to a different communication link. The identification value of the second identification bit corresponding to the first communication link is the third value, indicating that the second device instructs, through the control frame response frame, to transmit a data frame through the first communication link corresponding to the second identification bit.

[0323] In a case where the second device supports multi-link communication under the first communication mode, the second communication parameter indicated by the initial control frame is a communication parameter for transmitting the data frame through the first communication link.

[0324] In some embodiments, the parameter value of the second communication parameter indicated by the control frame response frame may be the same as or different from the parameter value of the first communication parameter.

[0325] When the parameter value of the second communication parameter is different from the parameter value of the first communication parameter, the control frame response frame is further used to indicate that the second device is currently transmitting data in at least two communication modes including the first communication mode.

[0326] The parameter value of the second communication parameter is different from the parameter value of the first communication parameter, and may be at least one of a spatial stream parameter, a bandwidth parameter, or a modulation and coding strategy parameter.

[0327] As an example, the parameter value of the bandwidth parameter in the first communication parameter is 160MHz, and the parameter value of the bandwidth parameter in the second communication parameter is 140MHz, indicating that the second device can transmit data frames in the first communication mode at a bandwidth of 140MHz, and there are other communication modes for data transmission at a bandwidth of 20MHz.

[0328] When the parameter value of the second communication parameter is the same as the parameter value of the first communication parameter, the control frame response frame is used to indicate that the second device currently performs data transmission only in the first communication mode.

[0329] It should be noted that when the first device and the second device support multi-link communication under the first communication mode, the parameter value of the first communication parameter is the same as the parameter value of the second communication parameter. In essence, the parameter value of the communication parameter corresponding to the first communication link in the first communication parameter is the same as the parameter value of the second communication parameter, and the first communication link is the communication link for data transmission indicated by the second device through the control frame response frame.

[0330] In some embodiments, the initial control frame is further used to indicate second time information.

[0331] The second time information may include at least one of the following:

[0332] a time interval during which the second device transmits data in the first communication mode;

[0333] The time interval during which the second device performs data transmission in other communication modes.

[0334] For example, the second time information may include a time interval during which the second device transmits data in a Wi-Fi communication manner.

[0335] For example, the second time information may include a time interval during which the second device transmits data in a communication manner other than the Wi-Fi communication manner.

[0336] Among them, the first communication mode can be a Wi-Fi communication mode, and other communication modes can be one or more of a Bluetooth (BT) communication mode, a New Radio (NR) communication mode, a Long Term Evolution (Long Term Evolution) communication mode, an Ultra Wide Band (UWB) communication mode, or a Zigbee communication mode.

[0337] It should be noted that the above-mentioned communication modes other than the first communication mode are merely examples, and may specifically be any other wireless communication mode other than the Wi-Fi communication mode, which will not be described in detail here.

[0338] Step S63: Transmit the data frame in the first communication mode according to the second communication parameter.

[0339] In some embodiments, the second device may receive, in the first communication mode, according to the second communication parameters, a data frame transmitted in the first communication mode according to the second communication parameters after the first device receives the control frame response frame.

[0340] As an example, the first device sends a data frame to the second device in a first communication mode (such as a Wi-Fi communication mode) according to the spatial stream parameter, the modulation and coding strategy parameter, and the bandwidth parameter in the second communication parameter.

[0341] In some embodiments, when the first device and the second device support multi-link communication in a first communication mode, the second device can receive a data frame transmitted by the first device in the first communication mode over the first communication link according to the second communication parameter. The first communication link is the communication link for transmitting the data frame indicated by the control frame response frame.

[0342] In some embodiments, when the control frame response frame also includes second time information, the second device can receive the data frame transmitted by the first device in the first communication mode within the time interval when the second device transmits data in the first communication mode according to the second communication parameters.

[0343] In some embodiments, before the first device sends an initial control frame in the first communication mode and the second device sends a control frame response frame in the first communication mode, the second device can receive the first wireless frame sent by the first device in the first communication mode, and the second device can send a second wireless frame to the first device in the first communication mode.

[0345] As an example, the first device may be a STA, the second device may be an AP, the first radio frame may be an association request frame sent by the first device to the second device, and the second radio frame may be an association response frame sent by the second device to the first device.

[0346] As an example, the first device may be an AP, the second device may be an STA, the second radio frame may be an association request frame sent by the second device to the first device, and the first radio frame may be an association response frame sent by the first device to the second device.

[0347] Optionally, the first radio frame is used to indicate that the first device supports data transmission in at least two communication modes including the first communication mode.

[0348] That is, the first radio frame is used to indicate that the first device has the ability to coexist with other communication modes and the first communication mode.

[0349] Among them, the first wireless frame may include a third identification bit, and the third identification bit indicates through a third value that the first device supports data transmission in at least two communication modes including the first communication mode, that is, the third value indicates that the first device has the ability to coexist with the first communication mode and other communication modes.
