[0035] The embodiments of the present disclosure provide a communication method, a device, and a storage medium.

[0036] In a first aspect, an embodiment of the present disclosure provides a communication method, which is applied to a first communication device and includes:

[0037] receiving a data frame after negotiating with the second communication device to establish a block acknowledgement (BA) mechanism;

[0038] A first radio frame is sent, where the first radio frame is used to indicate a coexistence activity state within the device of the first communication device during a data frame reception process and / or after completing the data frame reception.

[0039] In the above embodiment, the first communication device can receive data frames sent by the second communication device after negotiating with the second communication device to establish a BA mechanism, and can actively indicate the coexistence activity status of the first communication device during the reception of the data frame and / or after completing the reception of the data frame through the first wireless frame, so that the second communication device controls the sending of the data frame according to the coexistence activity status of the first communication device, thereby avoiding the transmission of the data frame from being interfered with by the coexistence activity of the first communication device, affecting the transmission quality of the data frame.

[0040] In conjunction with some embodiments of the first aspect, in some embodiments, sending the first radio frame includes at least one of the following:

[0041] sending a first radio frame when there is in-device coexistence activity during reception of the data frame;

[0042] The first radio frame is sent after receiving the second radio frame, where the second radio frame is used to request the first communication device to perform BA feedback, and the second radio frame includes a BA request frame or a multi-user BA request frame.

[0043] In the above embodiment, the first communication device can send the first wireless frame when there is coexistence activity within the device during the reception of the data frame, or can send the first wireless frame after completing the reception of the data frame and receiving the second wireless frame, which is conducive to improving the indication mechanism of the coexistence activity status of the first wireless frame during the reception of the data frame and / or after completing the reception of the data frame.

[0044] In conjunction with some embodiments of the first aspect, in some embodiments, the first radio frame includes a first identification bit. If the first radio frame is sent during the reception of a data frame, the identification value of the first identification bit is a first value. The first radio frame is used to indicate that the first communication device has an in-device coexistence activity during the reception of the data frame.

[0045] If the first wireless frame is sent after receiving the second wireless frame, when the identification value of the first identification bit is the first value, the first wireless frame is used to indicate that there is in-device coexistence activity after the first communication device completes reception of the data frame; when the identification value of the first identification bit is the second value, the first wireless frame is used to indicate that there is no in-device coexistence activity during and after the first communication device completes reception of the data frame.

[0046] In the above embodiment, if the first communication device sends a first wireless frame during the reception of a data frame, the first wireless frame can be used to promptly indicate to the first communication device that there is an in-device coexistence activity during the reception of the data frame, so that the second communication device can control the transmission of the data frame, thereby avoiding data frame loss and resource waste caused by interference with the transmission of the data frame caused by the in-device coexistence activity. After the first communication device completes the reception of the data frame and receives the second wireless frame for requesting BA feedback, it can indicate to the first communication device whether there is an in-device coexistence activity after completing the reception of the data frame while performing BA feedback through the first wireless frame. This is beneficial for the device to associate subsequent data frame transmissions according to the in-device coexistence activity of the first communication device, thereby improving the efficiency of data frame transmission.

[0047] In combination with some embodiments of the first aspect, in some embodiments, when the identification value of the above-mentioned first identification bit is a first value, the above-mentioned first wireless frame also includes a first identification field, and the above-mentioned first identification field is used to indicate the duration of the coexistence activity within the device where the above-mentioned first communication device exists.

[0048] In some embodiments, when there is coexistence activity within the device, the first communication device can also indicate the duration of the coexistence activity within the device through the first identification field, which is beneficial for the second communication device to control the transmission of data frames according to the duration of the coexistence activity within the device, thereby improving the transmission quality of the data frames and avoiding waste of resources.

[0049] In combination with some embodiments of the first aspect, in some embodiments, the above-mentioned first wireless frame also includes a second identification field, and the above-mentioned second identification field is used to indicate the data frame reception status of the above-mentioned first communication device.

[0050] In some embodiments, in the presence of coexistence activities within the device, the first communication device can also indicate the data frame reception status through the second identification field, which is beneficial for the second communication device to quickly determine whether there are any unreceived data frames of the first communication device based on the second identification field, and then transmit the unreceived data frames to the first communication device in a timely manner to ensure the complete transmission of the data frames.

[0051] In conjunction with some embodiments of the first aspect, in some embodiments, when the first communications device has in-device coexistence activity, the method further includes at least one of the following:

[0052] suspending reception of data frames for a duration of the in-device coexistence activity in which the first communication device exists;

[0053] When there is a first data frame that has not been received by the first communication device, the first data frame is received after a duration of the in-device coexistence activity in which the first communication device exists ends.

[0054] In the above embodiment, when an in-device coexistence activity occurs, the first communications device may suspend receiving data frames for the duration of the in-device coexistence activity, thereby preventing the in-device coexistence activity from interfering with the reception of data frames, thereby avoiding data frame loss and resource waste. Furthermore, when an in-device coexistence activity occurs, if the first communications device has unreceived first data frames, it may receive the first data frames again after the duration of the in-device coexistence activity expires, thereby effectively ensuring the integrity of data frame reception and effectively preventing the in-device coexistence activity from interfering with data frame transmission for the duration, thereby improving communication quality.

[0055] In conjunction with some embodiments of the first aspect, in some embodiments, when there is no in-device coexistence activity on the first communication device, the method further includes:

[0056] When the first communication device has an unreceived first data frame, the first communication device receives the first data frame.

[0057] In the above embodiment, when there is no coexistence activity within the device, if there is an unreceived first data frame, the first communication device can receive the first data frame in a timely manner, thereby maintaining the reception integrity of the data frame and improving the reliability of data frame transmission.

[0058] In a second aspect, an embodiment of the present disclosure provides a communication method, which is applied to a second communication device and includes:

[0059] Sending a data frame after negotiating with the first communication device to establish a BA mechanism;

[0060] A first radio frame is received, where the first radio frame is used to indicate a coexistence activity state within the device of the first communication device during a data frame reception process and / or after completing the data frame reception.

[0061] In the above embodiment, the second communication device can send data frames to the first communication device after negotiating with the first communication device to establish a BA mechanism, and can determine the coexistence activity status of the first communication device during the reception of the data frame and / or after completing the reception of the data frame through the first wireless frame actively sent by the first communication device, so as to control the sending of the data frame according to the coexistence activity status of the first communication device, thereby avoiding the transmission of the data frame from being interfered with by the coexistence activity of the first communication device, thereby affecting the transmission quality of the data frame.

[0062] In conjunction with some embodiments of the second aspect, in some embodiments, the receiving of the first radio frame includes at least one of the following:

[0064] The first radio frame is received after sending the second radio frame, where the second radio frame is used to request the first communication device to perform BA feedback, and the second radio frame includes a BA request frame or a multi-user BA request frame.

[0065] In the above embodiment, the second communication device can receive the first wireless frame when there is coexistence activity within the device during the reception of the data frame by the first communication device, or can receive the first wireless frame after the first communication device completes the reception of the data frame and receives the second wireless frame, which is conducive to improving the indication mechanism of the coexistence activity status of the first wireless frame during the reception of the data frame and / or after the completion of the data frame reception.

[0066] In conjunction with some embodiments of the second aspect, in some embodiments, the first radio frame includes a first identification bit. If the first radio frame is received during the transmission of a data frame, the identification value of the first identification bit is a first value, and the first radio frame is used to indicate that the first communication device has an in-device coexistence activity during the reception of the data frame.

[0067] If the first wireless frame is received after sending the second wireless frame, when the identification value of the first identification bit is the first value, the first wireless frame is used to indicate that there is in-device coexistence activity after the first communication device completes reception of the data frame; when the identification value of the first identification bit is the second value, the first wireless frame is used to indicate that there is no in-device coexistence activity during and after the first communication device completes reception of the data frame.

[0068] In the above embodiment, if the first communication device sends a first wireless frame during the reception of a data frame, the first wireless frame can be used to promptly indicate to the first communication device that there is an in-device coexistence activity during the reception of the data frame, so that the second communication device can control the transmission of the data frame, thereby avoiding data frame loss and resource waste caused by interference with the transmission of the data frame caused by the in-device coexistence activity. After the first communication device completes the reception of the data frame and receives the second wireless frame for requesting BA feedback, it can perform BA feedback through the first wireless frame while indicating to the first communication device whether there is an in-device coexistence activity after completing the reception of the data frame. This is beneficial for the second communication device to associate subsequent data frame transmissions according to the in-device coexistence activity of the first communication device, thereby improving the efficiency of data frame transmission.

[0069] In combination with some embodiments of the second aspect, in some embodiments, when the identification value of the above-mentioned first identification bit is the first value, the above-mentioned first wireless frame also includes a first identification field, and the above-mentioned first identification field is used to indicate the duration of the coexistence activity within the device where the above-mentioned first communication device exists.

[0070] In some embodiments, when there is in-device coexistence activity in the first communication device, the second communication device can also determine the duration of the in-device coexistence activity of the first communication device through the first identification field, which is conducive to controlling the transmission of data frames according to the duration of the in-device coexistence activity, thereby improving the transmission quality of data frames and avoiding waste of resources.

[0071] In combination with some embodiments of the second aspect, in some embodiments, the above-mentioned first wireless frame also includes a second identification field, and the above-mentioned second identification field is used to indicate the data frame reception status of the above-mentioned first communication device.

[0072] In some embodiments, when there is in-device coexistence activity on the first communication device, the second communication device can also determine the data frame reception status of the first communication device through the second identification field, which is conducive to quickly determining whether the first communication device has unreceived data frames based on the second identification field, and then timely transmitting the unreceived data frames to the first communication device to ensure the complete transmission of the data frames.

[0073] In conjunction with some embodiments of the second aspect, in some embodiments, when the first communication device has in-device coexistence activity, the method further includes at least one of the following:

[0074] suspending transmission of data frames for a duration of the in-device coexistence activity in which the first communication device exists;

[0075] When there is a first data frame that has not been received by the first communication device, the first data frame is sent after a duration of the in-device coexistence activity in which the first communication device exists ends.

[0076] In the above embodiment, when the first communication device is experiencing in-device coexistence activity, the second communication device may suspend sending data frames for the duration of the in-device coexistence activity, thereby preventing the in-device coexistence activity from interfering with the reception of data frames, thereby avoiding data frame loss and resource waste. Furthermore, when the first communication device is experiencing in-device coexistence activity, if the first communication device has a first data frame that has not been received, the second communication device may resend the first data frame after the duration of the in-device coexistence activity has expired, thereby effectively ensuring the reception integrity of the data frame and effectively preventing the in-device coexistence activity from interfering with the transmission of data frames for the duration, thereby improving communication quality.

[0077] In conjunction with some embodiments of the second aspect, in some embodiments, when there is no in-device coexistence activity on the first communication device, the method further includes:

[0110] With the development of wireless communication technology, the integration of terminal devices is becoming increasingly higher. A terminal device often supports multiple wireless communication protocols, integrates multiple wireless communication modules, and simultaneously accesses multiple wireless networks, such as Wireless Local Area Networks (WLAN), Long Term Evolution (LTE) systems, Bluetooth (BT), and Global Navigation Satellite Systems (GNSS).

[0111] The simultaneous communication of multiple communication modes means that the communication devices have in-device coexistence (IDC). In this case, the multiple communication modes may interfere with each other, resulting in communication failure or performance loss.

[0112] For example, when the communication frequency bands of different communication systems are adjacent, the transmission operation of one communication system will interfere with the reception operation of another communication system. As an example, Wi-Fi is adjacent to frequency bands such as LTW Band 40 and LTE Band 7. When the frequency components fall into the operating frequency bands of adjacent channels, it will cause communication interference in adjacent channels. In addition, when multiple wireless communication modules exist at the same time, the physical spacing between the radio frequency (RF) modules of each communication module is relatively small. When working at the same time, the communications between the communication systems will interfere with each other, affecting the transmission and reception of each communication module.

[0113] For example, both Wi-Fi and BT operate in the 2.4GHz frequency band, and in most communication devices, Wi-Fi and BT modules share antennas. Therefore, mutual interference between Wi-Fi and BT communications also occurs. Furthermore, as the bandwidth of wireless communication systems increases and becomes increasingly abundant, the problem of interference between multiple wireless communications within devices becomes increasingly severe, reducing the reliability of data transmission between devices. Therefore, effectively managing the coexistence of activities within a single device and avoiding the communication interference caused by these activities has become an urgent issue.

[0114] To address the above issues, the following will further describe the technical solutions in the embodiments of the present disclosure in a clear and complete manner with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure and do not constitute all the embodiments. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present disclosure without creative effort shall fall within the scope of protection of the present disclosure.

[0118] In some embodiments, the first communication device 101 and the second communication device 102 may be terminal devices or network devices with Wi-Fi chips.

[0123] Figure 2a is one of the interactive schematic diagrams of the communication method shown in the embodiment of the present disclosure. The communication method shown in Figure 2a includes:

[0124] S201: The first communication device receives a data frame after negotiating with the second communication device to establish a BA mechanism.

[0125] In some embodiments, the first communication device and the second communication device may be the responder and the initiator of the BA mechanism, respectively, to negotiate the BA mechanism. For example, the first communication device may be called a Recipient STA, and the second communication device may be called an Originating STA.

[0126] Specifically, when the second communication device and the first communication device are negotiating the BA mechanism, the second communication device may send an Add Block Acknowledgment (ADDBA) request frame to the first communication device to request to negotiate with the first communication device to establish the BA mechanism.

[0127] Furthermore, after receiving the ADDBA request frame, the first communication device may send an ADDBA response frame to the second communication device to instruct the establishment of a BA mechanism.

[0128] In some embodiments, after the first communication device and the second communication device negotiate to establish a BA mechanism, the second communication device may send at least one data frame to the first communication device, and the first communication device receives the data frame sent by the second communication device after negotiating to establish a BA mechanism with the second communication device.

[0129] S202 : When an in-device coexistence activity occurs during a data frame reception process, the first communication device sends a first radio frame, where the first radio frame is used to indicate that the in-device coexistence activity occurs during a data frame reception process.

[0130] In some embodiments, the first communications device may determine in real time whether there is an in-device coexistence activity on the first communications device during the process of receiving a data frame sent by the second communications device.

[0131] When there is an in-device coexistence activity during the reception of the data frame by the first communication device, the first communication device may send a first radio frame to the second communication device.

[0132] The first radio frame is used to indicate that there is in-device coexistence activity during the reception of the data frame by the first communication device.

[0133] Optionally, the first radio frame includes a first flag bit, and the identification value of the first flag bit is a first value. When the identification value of the first flag bit is the first value, the first radio frame is used to indicate that the first communication device has in-device coexistence activity during the reception of the data frame.

[0134] The first value may be 1 or other values, which are not limited here.

[0135] In some embodiments, the first radio frame may be a BA frame.

[0136] In some embodiments, the first radio frame is a BA frame, and the first radio frame includes a BA control field.

[0137] As an example, the format of the BA Control field in the first radio frame may be as follows:

[0138] The BA Control field includes an in-device coexistence activity existence (IDC Activities Existence) field, and the IDC Activities Existence field is the first flag bit.

[0139] When the first communication device sends the first radio frame during the data frame reception process, the identification value of the IDC Activities Existence field is the first value. At this time, the first radio frame is used to indicate that the first communication device has in-device coexistence activities during the data frame reception process.

[0140] S203: The second communication device suspends sending data frames before the duration of the in-device coexistence activity in which the first communication device exists ends.

[0141] In some embodiments, if the second communications device receives the first radio frame while sending a data frame to the first communications device, the second communications device may determine that the first radio frame indicates that the first communications device has IDC activity during reception of the data frame.

[0142] Optionally, when the first wireless frame includes a first identification bit, if the second communication device receives the first wireless frame while sending a data frame to the first communication device, and the identification value of the first identification bit is the first value, the second communication device can determine that there is in-device coexistence activity during the reception of the data frame by the first communication device.

[0143] In some embodiments, upon determining that the first communications device has in-device coexistence activity during data frame reception, the second communications device may suspend sending data frames to the first communications device for the duration of the in-device coexistence activity on the first communications device.

[0144] In some embodiments, when the first wireless frame is used to indicate that the first communication device has in-device coexistence activity during the reception of the data frame, the first wireless frame also includes a first identification field, and the first identification field is used to indicate the duration of the in-device coexistence activity of the first communication device.

[0145] Optionally, the first radio frame includes a first identification bit, and the first communication device sends the first radio frame when there is an in-device coexistence activity during the reception of the data frame, and when the identification value of the first identification bit is a first value, the first radio frame is used to indicate that there is an in-device coexistence activity during the reception of the data frame by the first communication device. At this time, the first radio frame also includes a first identification field, and the first identification field is used to indicate the duration of the in-device coexistence activity of the first communication device.

[0146] In some embodiments, the first radio frame is a BA frame, and the first radio frame includes a BA information field.

[0147] As an example, the format of the BA Information field in the first radio frame may be as follows:

[0148] The BA Information field includes an in-device coexistence activity duration (IDC Activities Duration) field, and the IDC Activities Duration field is a first identification field.

[0149] When the first communication device sends a first wireless frame during the reception process of the data frame, the first wireless frame is used to indicate that the first communication device has an in-device coexistence activity during the reception process of the data frame (such as the identification value of the first identification bit is the first value), and the IDC Activities Duration field is used to indicate the duration of the in-device coexistence activity of the first communication device.

[0150] As an example, a second communications device receives a first radio frame while transmitting a data frame to a first communications device. The second communications device may determine that the first communications device engaged in in-device coexistence activity during the data frame reception process and may determine the duration of the in-device coexistence activity on the first communications device based on the first identification field in the first radio frame. In this case, the second communications device may suspend transmitting data frames to the first communications device for the duration of the in-device coexistence activity on the first communications device.

[0151] S204: When there is a first data frame that has not been received by the first communication device, the second communication device sends the first data frame after the duration of the in-device coexistence activity in which the first communication device exists ends.

[0152] In some embodiments, if a second communications device receives a first radio frame while transmitting a data frame to a first communications device, the second communications device determines that the first communications device engaged in in-device coexistence activity during the reception of the data frame. In this case, if the first communications device has not received the first data frame, the second communications device may transmit the first data frame to the first communications device after the duration of the in-device coexistence activity with the first communications device expires.

[0153] The first data frame may include a data frame that the first communication device has not received before sending the first radio frame, and a data frame that the second communication device has not sent to the first communication device when receiving the first radio frame.

[0154] In some embodiments, the first radio frame includes a second identification field, and the second identification field is used to indicate a data frame reception status of the first communication device.

[0155] After receiving the first radio frame, the second communication device may determine the data frame reception status of the first communication device according to the second identification field in the first radio frame, and further determine whether the first communication device has any unreceived first data frame.

[0156] In some embodiments, the first wireless frame may be a BA frame, the first wireless frame includes a Block Ack Bitmap field, the Block Ack Bitmap field includes at least one bit, each bit corresponds to a data frame, and the Block Ack Bitmap field is a second identification field.

[0157] Specifically, if the nth bit of the Block Ack Bitmap field is the third value, it indicates that the first communications device has received a data frame with a sequence number SN and a fragment number FN, for example, a media access control protocol data unit (MAC Protocol Data Unit, MPDU) with a sequence number SN and a fragment number FN. Where n = 4 × (SN - SSN) + FN, where SSN is the value of the starting sequence number subfield of the Block Ack Start Sequence Control subfield, and a modulo 4096 operation is performed on the sequence number. If the nth bit of the Block Ack Bitmap field is the fourth value, it indicates that the first communications device has not received the corresponding data frame.

[0158] The third value and the fourth value are different values, for example, the third value is 1 and the fourth value is 0, which is not limited here.

[0159] In this case, after the second communication device receives the first wireless frame, it can determine whether the first communication device has any unreceived first data frame based on the Block Ack Bitmap field, and if the first communication device has any unreceived first data frame, send the first data frame to the first communication device after the duration of the coexistence activity within the device where the first communication device exists ends.

[0160] The communication method involved in the embodiments of the present disclosure may include at least one of the aforementioned steps and embodiments. For example, any one of steps S201 to S204 may be implemented as an independent embodiment, steps S201 to S203 may be implemented as an independent embodiment, steps S201, S202, and S204 may be implemented as independent embodiments, and steps S201 to S204 may be implemented as independent embodiments, but are not limited thereto.

[0162] S211 , the first communication device receives a data frame after negotiating with the second communication device to establish a BA mechanism.

[0163] In some embodiments, the first communication device and the second communication device may be the responder and the initiator of the BA mechanism, respectively, to negotiate the BA mechanism. For example, the first communication device may be called a Recipient STA, and the second communication device may be called an Originating STA.

[0164] Specifically, when the second communication device and the first communication device are negotiating the BA mechanism, the second communication device may send an ADDBA request frame to the first communication device to request to negotiate with the first communication device to establish the BA mechanism.

[0165] Furthermore, after receiving the ADDBA request frame, the first communication device may send an ADDBA response frame to the second communication device to instruct the establishment of a BA mechanism.

[0166] In some embodiments, after the first communication device and the second communication device negotiate to establish a BA mechanism, the second communication device may send at least one data frame to the first communication device, and the first communication device receives the data frame sent by the second communication device after negotiating to establish a BA mechanism with the second communication device.

[0167] S212 , when there is no in-device coexistence activity during the reception of the data frame, the first communication device receives a second radio frame after completing the reception of the data frame, where the second radio frame is used to request the first communication device to perform BA feedback.

[0168] In some embodiments, while receiving a data frame sent by a second communication device, the first communication device may determine in real time whether there is in-device coexistence activity on the first communication device. If there is no in-device coexistence activity on the first communication device during the data frame reception process, the first communication device may receive a second radio frame sent by the second communication device after completing reception of the data frame.

[0169] The second radio frame is used to request the first communication device to perform BA feedback.

[0170] Optionally, the second radio frame includes a BA request frame or a multi-user block acknowledgment request (Multi-User Block Acknowledgment Request) frame.

[0171] After confirming that the first communication device has completed receiving the data frame, it may send a BA frame to the second communication device to confirm the transmission status of the data frame.

[0172] S213, the first communication device sends a first radio frame after receiving the second radio frame, and the first radio frame is used to indicate that there is an in-device coexistence activity after the first communication device completes reception of the data frame, or is used to indicate that there is no in-device coexistence activity during the first communication device's reception of the data frame and after completing reception of the data frame.

[0173] In some embodiments, the first communications device may send the first radio frame to the second communications device after receiving the second radio frame.

[0174] The first radio frame is used to indicate at least one of the following:

[0175] The first communication device has an in-device coexistence activity after completing reception of the data frame;

[0176] There is no in-device coexistence activity during and after the first communications device receives the data frame.

[0177] In some embodiments, the first wireless frame includes a first identification bit, and when the identification value of the first identification bit is a first value, the first wireless frame is used to indicate that there is an in-device coexistence activity after the first communication device completes the reception of the data frame; when the identification value of the first identification bit is a second value, the first wireless frame is used to indicate that there is no in-device coexistence activity during the reception of the data frame and after the reception of the data frame is completed.

[0178] The first value and the second value are different values. For example, the first value may be 1 and the second value may be 0, which is not limited here.

[0179] In some embodiments, the first radio frame may be a BA frame.

[0180] In some embodiments, the first radio frame is a BA frame, and the first radio frame includes a BA Control field.

[0181] As an example, the format of the BA Control field in the first radio frame may be as follows:

[0182] The BA Control field includes an in-device coexistence activity existence (IDC Activities Existence) field, and the IDC Activities Existence field is the first flag bit.

[0183] If the first communication device sends the first radio frame after receiving the second radio frame, when the identification value of the IDC Activities Existence field is the first value, the first radio frame is used to indicate that there is an in-device coexistence activity after the first communication device completes reception of the data frame; when the identification value of the IDC Activities Existence field is the second value, the first radio frame is used to indicate that there is no in-device coexistence activity during the reception of the data frame and after the first communication device completes reception of the data frame.

[0184] S214: The second communication device determines whether there is an in-device coexistence activity on the first communication device.

[0185] In some embodiments, if the second communication device receives the first wireless frame after sending the second wireless frame to the first communication device, the second communication device can determine the in-device coexistence activity status of the first communication device during the reception of the data frame and / or after completing the reception of the data frame.

[0186] Optionally, the first wireless frame includes a first identification bit, and when the identification value of the first identification bit is a first value, the second communication device can determine that there is an in-device coexistence activity after the first communication device completes the reception of the data frame; when the identification value of the second identification bit is a second value, the second communication device can determine that there is no in-device coexistence activity during the reception of the data frame and / or after the first communication device completes the reception of the data frame.

[0187] In some embodiments, if the second communication device determines that there is in-device coexistence activity in the first communication device, such as determining that there is in-device coexistence activity in the first communication device after completing the reception of the data frame, step S215 is executed; if the second communication device determines that there is no in-device coexistence activity in the first communication device, such as determining that there is no in-device coexistence activity in the first communication device during the reception of the data frame and after completing the reception of the data frame, step S217 is executed.

[0188] S215 : The second communication device suspends sending data frames before the duration of the in-device coexistence activity in which the first communication device exists ends.

[0189] In some embodiments, when it is determined that the first communications device has in-device coexistence activity after completing reception of the data frame, the second communications device may suspend sending data frames to the first communications device for the duration of the in-device coexistence activity of the first communications device.

[0190] In some embodiments, when the first wireless frame is used to indicate that there is in-device coexistence activity after the first communication device completes reception of the data frame, the first wireless frame also includes a first identification field, and the first identification field is used to indicate the duration of the in-device coexistence activity of the first communication device.

[0191] Optionally, the first radio frame includes a first identification bit, and when the first communication device sends the first radio frame after receiving the second radio frame, and the identification value of the first identification bit is a first value, the first radio frame is used to indicate that there is an in-device coexistence activity after the first communication device completes reception of the data frame. In this case, the first radio frame also includes a first identification field, and the first identification field is used to indicate the duration of the in-device coexistence activity of the first communication device.

[0192] In some embodiments, the first radio frame is a BA frame, and the first radio frame includes a BA Information field.

[0193] As an example, the format of the BA Information field in the first radio frame may be as follows:

[0194] The BA Information field includes an in-device coexistence activity duration (IDC Activities Duration) field, and the IDC Activities Duration field is a first identification field.

[0195] When the first communication device sends the first radio frame after receiving the second radio frame, and the first radio frame is used to indicate that there is an in-device coexistence activity after the first communication device completes reception of the data frame (such as the identification value of the first identification bit is the first value), the IDC Activities Duration field is used to indicate the duration of the in-device coexistence activity of the first communication device.

[0196] As an example, after sending a second radio frame to a first communication device, the second communication device receives a first radio frame and can determine whether the first communication device has an in-device coexistence activity after completing the reception of the data frame based on the identification value of the first identification bit. When it is determined that the first communication device has an in-device coexistence activity after completing the reception of the data frame, the duration of the in-device coexistence activity of the first communication device can be determined based on the first identification field in the first radio frame. In this case, the second communication device can suspend sending data frames to the first communication device for the duration of the in-device coexistence activity of the first communication device.

[0197] S216 : When there is a first data frame that has not been received by the first communication device, the second communication device sends the first data frame after the duration of the in-device coexistence activity in which the first communication device exists ends.

[0198] In some embodiments, if the second communications device receives a first radio frame after sending a second radio frame to the first communications device, and determines based on the first radio frame that in-device coexistence activity occurs after the first communications device completes reception of a data frame, in this case, if the first communications device has not received the first data frame, the second communications device may send the first data frame to the first communications device after the duration of the in-device coexistence activity with the first communications device expires.

[0199] The first data frame may include a data frame that the first communication device has not received before sending the first radio frame, and a data frame that the second communication device has not sent to the first communication device when receiving the first radio frame.

[0200] In some embodiments, the first radio frame includes a second identification field, and the second identification field is used to indicate a data frame reception status of the first communication device.

[0201] After receiving the first radio frame, the second communication device may determine the data frame reception status of the first communication device according to the second identification field in the first radio frame, and further determine whether the first communication device has any unreceived first data frame.

[0202] In some embodiments, the first radio frame may be a BA frame, the first radio frame includes a Block Ack Bitmap field, the Block Ack Bitmap field includes at least one bit, each bit corresponds to a data frame, and the Block Ack Bitmap field is a second identification field.

[0203] Specifically, if the nth bit of the Block Ack Bitmap field is the third value, it indicates that the first communications device has received a data frame with a sequence number SN and a fragment number FN, for example, a media access control protocol data unit (MAC Protocol Data Unit, MPDU) with a sequence number SN and a fragment number FN. Where n = 4 × (SN - SSN) + FN, where SSN is the value of the starting sequence number subfield of the Block Ack Start Sequence Control subfield, and a modulo 4096 operation is performed on the sequence number. If the nth bit of the Block Ack Bitmap field is the fourth value, it indicates that the first communications device has not received the corresponding data frame.

[0204] The third value and the fourth value are different values, for example, the third value is 1 and the fourth value is 0, which is not limited here.

[0205] In this case, after the second communication device receives the first wireless frame, it can determine whether the first communication device has any unreceived first data frame based on the Block Ack Bitmap field, and if the first communication device has any unreceived first data frame, send the first data frame to the first communication device after the duration of the coexistence activity within the device where the first communication device exists ends.

[0206] S217: When the first communication device has a first data frame that has not been received, the second communication device sends the first data frame.

[0207] In some embodiments, if the second communication device receives a first wireless frame after sending a second wireless frame to the first communication device, and determines based on the first wireless frame that there is no in-device coexistence activity during the reception of the data frame and after the reception of the data frame is completed, the second communication device can determine whether the first communication device has an unreceived first data frame (see step S216 for the specific implementation method).

[0208] When it is determined that the first communication device has not received the first data frame, the second communication device may directly send the first data frame to the first communication device after receiving the first wireless frame. When it is determined that the first communication device has not received the first data frame, the second communication device may continue to send other data frames to the first communication device.

[0209] The communication method involved in the embodiments of the present disclosure may include at least one of the aforementioned steps and embodiments. For example, any one of steps S211 to S217 may be implemented as an independent embodiment, steps S211 to S216 may be implemented as an independent embodiment, steps S211 to S214 and step S217 may be implemented as independent embodiments, and steps S211 to S217 may be implemented as an independent embodiment, but are not limited thereto.

[0210] The communication method provided by the embodiment of the present disclosure is further described below with reference to examples.

[0211] After the first communication device negotiates with the second communication device to establish a BA mechanism, the second communication device sends a data frame to the first communication device.

[0212] Case 1:

[0213] When the first communications device has an in-device coexistence activity during reception of a data frame, the first communications device may send a BA frame to the second communications device.

[0214] The BA frame includes a first identification bit, and the identification value of the first identification bit is a first value, which is used to indicate that there is in-device coexistence activity during the reception of the data frame by the first communication device.

[0215] The BA frame includes a first identification field and a second identification field, the first identification field is used to indicate the duration of the coexistence activity within the device, and the second identification field is used to indicate the data frame reception status of the first communication device.

[0216] In this case, the second communication device suspends sending data frames to the first communication device during the duration of the in-device coexistence activity of the first communication device. When the second communication device determines, based on the second identification field, that the first communication device has unreceived data frames, the second communication device sends the previously unreceived data frames to the first communication device after the duration of the in-device coexistence activity of the first communication device.

[0217] Case 2:

[0218] When there is no in-device coexistence activity during the process of the first communication device receiving a data frame, the first communication device can receive a BA request frame or an MU-BAR frame sent by the second communication device, and send a BA frame to the second communication device after receiving the BA request frame or the MU-BAR frame.

[0219] The BA frame includes a first identification bit. When the first communication device has an in-device coexistence activity after completing reception of the data frame, the identification value of the first identification bit is a first value, indicating that the first communication device has an in-device coexistence activity after completing reception of the data frame. When the first communication device has no in-device coexistence activity after completing reception of the data frame, the identification value of the first identification bit is a second value, indicating that the first communication device has no in-device coexistence activity during and after receiving the data frame.

[0220] When the identification value of the first identification bit is the first value, the BA frame further includes a first identification field, and the first identification field is used to indicate the duration of the coexistence activity within the device.

[0221] The BA frame further includes a second identification field, and the second identification field is used to indicate the data frame reception status of the first communication device.

[0222] In this case, after the second communication device receives the BA frame, if the first identification field is the first value, it is determined that the first communication device has an in-device coexistence activity after completing reception of the data frame. The second communication device then suspends sending data frames to the first communication device for the duration of the in-device coexistence activity of the first communication device, and if it is determined based on the second identification field that the first communication device has not received any data frames, the second communication device sends the previously unreceived data frames to the first communication device after the duration of the in-device coexistence activity of the first communication device.

[0223] After the second communication device receives the BA frame, if the first flag bit is the second value, it determines that no intra-device coexistence activity occurred on the first communication device during and after receiving the data frame. Furthermore, if the second communication device determines, based on the second flag field, that the first communication device has unreceived data frames, the second communication device transmits the previously unreceived data frames to the first communication device after receiving the BA frame.
