[0070] Figure 2 A flowchart of a data transmission method provided by an embodiment of the present disclosure; the data transmission method is executed by a first device, as Figure 2 shown, the above method may include the following steps:

[0071] Step 201, when the first device does not have a Transmission Opportunity (TXOP) for the first time period and there is target data to be sent to the second device within the first time period, send a first message to the second device.

[0072] Wherein, the first message is used to indicate the target data to be sent by the first device, and the target delay corresponding to the target data is less than a threshold.

[0073] Wherein, the first device not having a Transmission Opportunity (TXOP) for the first time period means that the access network device (such as a Wireless Access Point (AP), etc.) has allocated the Transmission Opportunity for the first time period to other devices in the network. For example, if the wireless access network has allocated the TXOP for the first time period to itself, that is, the access network device has the TXOP for the first time period, then the first device can be a terminal; or, if the wireless access network has allocated the TXOP for the first time period to the first terminal, then the first device is the access network device, or a second terminal other than the first terminal. There is no limitation on this.

[0074] Wherein, the first time period can be the time period corresponding to the Transmission Opportunity at the current moment.

[0075] Wherein, the target delay corresponding to the target data can be the maximum required delay of the target data. The target data can also be referred to as low-latency data. For example, the target data can be voice calls, video conferences, online live broadcasts, real-time monitoring, interactive games, etc.

[0076] In some embodiments, the first message can also be referred to as a low-latency indication message, an indication message, a Low Latency Indication (LLI). The present disclosure does not limit this.

[0077] Step 202, obtain communication resources, wherein the communication resources are used for the first device to send the target data.

[0078] Wherein, the communication resources can include Transmission Opportunities, Resource Units (RUs), etc. The present disclosure does not limit this.

[0079] In some embodiments, if the first device is a terminal, it can receive a Trigger Frame sent by the access network device, wherein the Trigger Frame includes the communication resources for sending the target data. If the first device is the access network device, then the access network device determines the communication resources for itself to send the target data.

[0080] Step 203, based on the communication resources, send the target data to the second device.

[0081] In an embodiment of the present disclosure, after determining communication resources for sending target data, the target data can be sent to a second device based on the communication resources.

[0082] In some embodiments, a fourth message sent by the second device is received, where the fourth message is used to indicate that the second device has received the target data. Thus, the first device can determine that the second device has successfully received the target data.

[0083] In an embodiment of the present disclosure, when the first device does not have a transmission opportunity TXOP for a first time period and there is target data to be sent to the second device within the first time period, a first message for indicating the target data to be sent by the first device is sent to the second device, then communication resources for sending the target data are obtained, and finally, the target data is sent to the second device based on the communication resources. Thus, when the first device has low-latency data to be sent but no transmission opportunity, the first message can be sent first, so as to obtain communication resources for sending the low-latency data, complete the sending of the low-latency data, and thus ensure the timely sending of the low-latency data and improve the user experience in a low-latency scenario.

[0084] Figure 3 FIG. is a schematic flowchart of another data transmission method provided by an embodiment of the present disclosure. The data transmission method is executed by a first device, where the first device is a terminal, such as Figure 3 As shown, the data transmission method may include the following steps:

[0085] Step 301, when the first device is a terminal, the second device is an access network device, and the access network device has a TXOP for a first time period, send a first message to the second device.

[0086] Wherein, the first message is used to indicate the target data to be sent by the first device, and the target latency corresponding to the target data is less than a threshold.

[0087] Wherein, the first message further includes description information corresponding to the target data.

[0088] In some embodiments, the description information includes at least one of the following:

[0089] The type of the target data;

[0090] The target latency corresponding to the target data;

[0091] The first transmission priority corresponding to the target data.

[0092] Wherein, the type of the target data may be voice call, video conference, online anchor, real-time monitoring, interactive game, etc. The present disclosure does not make any limitation thereto.

[0093] Among them, the first transmission priority corresponding to the target data can be used to indicate the transmission priority of the target data.

[0094] In some embodiments, the first transmission priority corresponding to the target data can be determined according to the target delay of the target data. The lower the target delay, the higher the corresponding first transmission priority.

[0095] In some embodiments, the first priority corresponding to the target data can also be determined according to the type of the target data. Optionally, the transmission priority corresponding to each data type can be set in advance, and then the first transmission priority corresponding to the type of the target data is determined.

[0096] In some embodiments, one terminal can send a first message to the access network device, or multiple terminals can send first messages to the access network device simultaneously.

[0097] It should be noted that since the access network device has the TXOP of the first time period, the access network device sends low-delay data or non-low-delay data to some terminals during the first time period. After some terminals receive the data sent by the access network device, they will send a Block ACK (BA) message to the access network device. Therefore, when the terminal that is receiving data needs to send a first message to the access network device, the first message can be carried in the sent BA message. Thus, communication resources are saved.

[0098] Step 302: Receive a second message sent by the access network device, where the second message includes communication resources corresponding to the terminal.

[0099] Among them, the second message can be a Trigger Frame. In some embodiments, if multiple terminals send first messages to the access network device simultaneously, the second message can include the identifier of each terminal and the corresponding communication resources. Furthermore, each terminal can obtain its own communication resources from the second message according to its own identifier.

[0100] It should be noted that since the access network device has the TXOP of the first time period. Therefore, the access network device can send low-delay data or non-low-delay data to some terminals during the first time period. When the access network device receives the first message and is sending non-low-delay data, it can directly stop sending non-low-delay data and allocate communication resources for the terminal.

[0101] When the access network device is sending low-latency data when it receives the first message, it is necessary to compare the low-latency data being sent by the access network device with the transmission priority of the target data indicated by the first message. Furthermore, in the case where the first transmission priority of the target data is higher than the transmission priority of the low-latency data being sent by the access network device, stop sending the low-latency data and allocate communication resources for the terminal.

[0102] Step 303, based on the communication resources, send the target data to the second device.

[0103] In some embodiments, after sending the target data to the access network device, receive a fourth message sent by the access network device.

[0104] In some embodiments, the fourth message may be a Multi-STA Block ACK message. Among them, the Multi-STA Block ACK includes the terminal identifier corresponding to the received target data. The terminal can determine whether the access network device has sent the target data according to whether its own identifier is included in the Multi-STA Block ACK. If the Multi-STA Block ACK contains its own identifier, it is determined that the access network device has received the sent target data; if the Multi-STA Block ACK does not contain its own identifier, it is determined that the access network device has not received the sent target data.

[0105] In the embodiments of the present disclosure, when the first device is a terminal, the second device is an access network device, and the access network device has a TXOP for the first time period, send a first message for indicating the target data to be sent by the first device to the second device, where the first message contains a description message. Then, obtain communication resources by receiving the first message sent by the access network device. Finally, based on the communication resources, send the target data to the second device. Thus, when the first device is a terminal, the second device is an access network device, and the access network device has a TXOP for the first time period, the first message can be sent to the access network device first, and then based on the communication resources allocated by the access network device, the transmission of low-latency data can be completed, so as to ensure that the low-latency data of the terminal is sent to the access network device in time, improving the user experience in low-latency scenarios.

[0106] Figure 4 FIG. is a schematic flowchart of another data transmission method provided by an embodiment of the present disclosure. This data transmission method is executed by a first device, where the first device is an access network device, as Figure 4 shown, this data transmission method may include the following steps:

[0107] Step 401, when the first terminal has a TXOP for a first time period, the first device is an access network device, and the second device is the first terminal and / or the second terminal, receive first data sent by the first terminal, where the second terminal is a terminal without a TXOP for the first time period.

[0108] The first data can be low-latency data or non-low-latency data.

[0109] Step 402, determine a first transmission priority corresponding to the target data and a second transmission priority corresponding to the first data.

[0110] In some embodiments, when the first data is non-low-latency data, determine that the second transmission priority is the lowest transmission priority, that is, the second transmission priority is the priority for the last transmission. The first transmission priority is higher than the second transmission priority.

[0111] In some embodiments, the access network device can determine the first transmission priority of the target data according to at least one of the type of the target data and the target latency; determine the second transmission priority of the first data according to at least one of the type of the received first data and the latency requirement.

[0112] Step 403, when the first transmission priority is higher than the second transmission priority, send a first message to the first terminal and / or the second terminal.

[0113] The first message is used to indicate target data to be sent by the first device.

[0114] In some embodiments, the access network device can send the target data to the first terminal; or the second terminal; or the first terminal and the second terminal. Therefore, the first message can be sent to the first terminal, or the first message can be sent to the second terminal, or the first message can also be sent to the first terminal and the second terminal at the same time. The present disclosure does not limit this.

[0115] The first message is further used to instruct the first terminal to stop sending the first data.

[0116] It should be noted that since the first terminal sends the first data to the access network device during the first time period, and the access network device has target data to send to the first terminal and / or the second terminal. Therefore, it is necessary to instruct the first terminal to stop sending the first data, so that the access network device can send the target data to the first terminal and / or the second terminal.

[0117] In some embodiments, since the access network device sends a Block ACK (BA) message to the first terminal after receiving the first data, when the access network device needs to send the first message to the access network device, the first message can be carried in the BA message sent to the first terminal. Thus, communication resources can be saved.

[0118] In some embodiments, when the first transmission priority is equal to or higher than the second transmission priority, the first message is not sent to the first terminal and / or the second terminal, so that the first terminal continues to send the first data.

[0119] Step 404: Obtain communication resources, where the communication resources are used for the first device to send target data.

[0120] Step 405: Based on the communication resources, send the target data to the second device.

[0121] In the embodiments of the present disclosure, when the first terminal has a TXOP for the first time period, the first device is an access network device, and the second device is the first terminal and / or the second terminal, first receive the first data sent by the first terminal, and then when the first transmission priority corresponding to the target data is higher than the second transmission priority corresponding to the first data, send the first message to the first terminal and / or the second terminal, then obtain the communication resources for sending the target data, and finally based on the communication resources, send the target data to the second device. Thus, when the first terminal has a TXOP for the first time period, the first device is an access network device, and the second device is the first terminal and / or the second terminal, it can be determined whether the first transmission priority corresponding to the target data is higher than the second transmission priority corresponding to the first data, and then in the case of being higher, send the first message to the first terminal and / or the second terminal, so that it is possible to ensure that the low-latency data with the highest transmission priority is sent first, further improving the user experience in the low-latency scenario.

[0122] Figure 5 It is a schematic flowchart of another data transmission method provided by an embodiment of the present disclosure. The data transmission method is executed by a first device, where the first device is a first terminal without a TXOP for the first time period, as Figure 5 shown, the data transmission method may include the following steps:

[0123] Step 501: When the first terminal has a TXOP for the first time period, the first device is the second terminal, and the second device is the access network device, send the first message to the second device.

[0124] Wherein, the first message is used to indicate the target data to be sent by the first device, and the target latency corresponding to the target data is less than the threshold.

[0125] Among them, the second terminal is a terminal without a TXOP in the first time period.

[0126] It should be noted that since the first terminal has a TXOP in the first time period, the first terminal can send low-latency data or non-low-latency data to the radio access network in the first time period, while the second terminal cannot send low-latency data to the radio access network in the first time period. Therefore, when the second terminal has target data to be sent to the access network device, it needs to send a first message to the access network device.

[0127] Step 502, receive a third message sent by the access network device.

[0128] Among them, the third message can be a Trigger Frame.

[0129] It should be noted that the access network device can allocate communication resources only for the second terminal without changing the current communication resources of the first terminal; it can also re-allocate communication resources for the first terminal and the second terminal.

[0130] Therefore, the third message can include the communication resources corresponding to the second terminal. Or it can also include the communication resources corresponding to the first terminal and the second terminal respectively.

[0131] Step 503, send the target data to the second device based on the communication resources.

[0132] In the embodiment of the present disclosure, in the case where the first terminal has a TXOP in the first time period, the first device is the second terminal, and the second device is the access network device, a first message is sent to the second device, and then the communication resources allocated by the access network device for sending the target data are received. Finally, the target data is sent to the second device based on the communication resources. Thus, in the case where the first terminal has a TXOP in the first time period, the first device is the second terminal, and the second device is the access network device, the second terminal can timely send low-latency data to the access network device, improving the user experience in the low-latency scenario.

[0133] Figure 6 The flowchart of a data transmission method provided by an embodiment of the present disclosure, which is executed by a second device, as Figure 6 shown, the data transmission method may include the following steps:

[0134] Step 601, receive a first message sent by the first device.

[0135] Among them, the first message is used to indicate the target data to be sent by the first device, and the target latency corresponding to the target data is less than a threshold.

[0136] Among them, the first device does not have a Transmission Opportunity (TXOP) in the first time period, indicating that the access network device (such as a wireless Access Point (AP), etc.) has allocated the TXOP of the first time period to other devices in the network. For example, if the wireless access network allocates the TXOP of the first time period to itself, that is, the access network device has the TXOP of the first time period, then the first device can be a terminal; or, if the wireless access network allocates the TXOP of the first time period to the first terminal, then the first device is the access network device or a second terminal other than the first terminal. There is no limitation on this.

[0137] Among them, the first time period can be the time period corresponding to the transmission opportunity at the current moment.

[0138] Among them, the target delay corresponding to the target data can be the maximum delay required for the target data. The target data can also be referred to as low-latency data. For example, the target data can be voice calls, video conferences, online live broadcasts, real-time monitoring, interactive games, etc.

[0139] In some embodiments, the first message can also be referred to as a low-latency indication message, an indication message, or a Low Latency Indication (LLI). The present disclosure does not limit this.

[0140] Step 602, receive the target data sent by the first device.

[0141] In some embodiments, after receiving the target data sent by the first device, a fourth message can be sent to the first device, where the fourth message is used to indicate that the second device has received the target data. Thus, the first device can determine whether the sent target data has been successfully received by the second device.

[0142] In the embodiments of the present disclosure, the second device first receives the first message sent by the first device, where the first message is used to indicate the target data to be sent by the first device, and then receives the target data sent by the first device. Thus, it can ensure the timely transmission of low-latency data and improve the user experience in low-latency scenarios.

[0143] Figure 7 It is a schematic flowchart of a data transmission method provided by an embodiment of the present disclosure. The data transmission method is executed by a second device, where the second device is an access network device, such as Figure 7 As shown, the data transmission method may include the following steps:

[0144] Step 701, when the first device is a terminal, the second device is an access network device, and the access network device has the TXOP of the first time period, receive the first message sent by the first device.

[0145] Among them, the first message is used to indicate the target data to be sent by the first device.

[0146] Among them, the target delay corresponding to the target data is less than the threshold.

[0147] Among them, the first message also includes the description information corresponding to the target data.

[0148] In some embodiments, the description information includes at least one of the following:

[0149] The type of the target data;

[0150] The target delay corresponding to the target data;

[0151] The first transmission priority corresponding to the target data.

[0152] Among them, the type of the target data may be voice call, video conference, online anchor, real-time monitoring, interactive game, etc. The present disclosure does not limit this.

[0153] Among them, the first transmission priority corresponding to the target data can be used to indicate the transmission priority of the target data.

[0154] In some embodiments, the first transmission priority corresponding to the target data can be determined according to the target delay of the target data. The lower the target delay, the higher the corresponding first transmission priority.

[0155] In some embodiments, the first priority corresponding to the target data can also be determined according to the type of the target data. Optionally, the transmission priority corresponding to each data type can be set in advance, and then the first transmission priority corresponding to the type of the target data is determined.

[0156] In some embodiments, the access network device can receive the first message sent by one terminal at the same time, or can also receive the first messages sent by multiple terminals. The present disclosure does not limit this.

[0157] Step 702: Determine the first transmission priority corresponding to the target data according to the description information.

[0158] In some embodiments, if the description information contains the first transmission priority, directly obtain the first transmission priority from the description information.

[0159] In some embodiments, if the description information does not contain the first transmission priority, the first transmission priority of the target data can be determined according to the type or the target delay of the target data in the description information.

[0160] Step 703: Determine the third transmission priority corresponding to the second data sent by the access network device.

[0161] In some embodiments, according to the type of the second data or the corresponding latency requirement, a third transmission priority of the second data is determined.

[0162] Step 704: When the first transmission priority is higher than the third transmission priority, stop transmitting the second data.

[0163] In some embodiments, when the first transmission priority is higher than the second transmission priority, in order to ensure the successful transmission and reception of the target data, the access network device needs to stop transmitting the second data so as to receive the target data sent by the terminal.

[0164] In some embodiments, if the access network device receives first messages sent by multiple terminals simultaneously, it is necessary to separately determine the first transmission priority corresponding to the target data to be sent by each terminal. When the first transmission priority corresponding to any target data is higher than the third transmission priority, stop transmitting the second data.

[0165] Step 705: Send a second message to the terminal, where the second message includes communication resources corresponding to the terminal.

[0166] The second message may be a Trigger Frame. In some embodiments, if multiple terminals separately send first messages to the access network device simultaneously, the second message may include the identifier of each terminal and the corresponding communication resources. Furthermore, each terminal can obtain its own communication resources from the second message according to its own identifier.

[0167] In some embodiments, when the first transmission priority is lower than or equal to the third transmission priority, continue to transmit the second data and do not send the second message to the terminal.

[0168] Step 706: Receive the target data sent by the first device.

[0169] In some embodiments, after receiving the target data sent by the first device, a fourth message may be sent to the terminal.

[0170] The fourth message may be a Multi-STA Block ACK message. The Multi-STA Block ACK includes the terminal identifier corresponding to the received target data. The terminal can determine whether the access network device has sent the target data according to whether its own identifier is included in the Multi-STA Block ACK. If the Multi-STA Block ACK contains its own identifier, it means that the access network device has received the sent target data; if the Multi-STA Block ACK does not contain its own identifier, it means that the access network device has not received the sent target data.

[0171] In an embodiment of the present disclosure, when the first device is a terminal, the second device is an access network device, and the access network device has a TXOP, the second device receives a first message sent by the first device and containing description information. Then, according to the description information, the second device determines a first transmission priority corresponding to the target data. When the first transmission priority is higher than a third transmission priority corresponding to the second data, the second device stops transmitting the second data and sends a second message including communication resources corresponding to the terminal to the terminal. Finally, the second device receives the target data sent by the first device. Thus, when the first transmission priority of the target data to be sent by the terminal is higher than the third transmission priority corresponding to the second data being sent by the access network device, communication resources for sending the target data can be allocated to the terminal, so that low-latency data with a higher transmission priority can be preferentially sent, improving the user experience in low-latency scenarios.

[0172] Figure 8 The flowchart of a data transmission method provided by an embodiment of the present disclosure is executed by a second device. When the second device is the first terminal and / or the second terminal, as Figure 8 shown, the data transmission method may include the following steps:

[0173] Step 801, when the first terminal has a TXOP for a first period, the first device is an access network device, and the second device is the first terminal and / or the second terminal, the second device receives a first message sent by the first device.

[0174] Wherein, the first message is used to indicate that the first device has target data to be sent, and the target latency corresponding to the target data is less than a threshold.

[0175] In some embodiments, the access network device may send the target data to the first terminal; or the second terminal; or the first terminal and the second terminal. Therefore, the first message may be sent to the first terminal, or the first message may be sent to the second terminal, or the first message may also be sent to the first terminal and the second terminal simultaneously. The present disclosure does not limit this.

[0176] Wherein, the first message is further used to indicate that the first terminal stops sending the first data.

[0177] In some embodiments, when the second device is the first terminal, after receiving the first message, the first terminal stops sending the first data to the access network device.

[0178] Step 802, the second device receives the target data sent by the first device.

[0179] In an embodiment of the present disclosure, when the first terminal has a TXOP for a first time period, the first device is an access network device, and the second device is the first terminal and / or the second terminal, a first message sent by the first device is received. The first message is further used to instruct the first terminal to stop sending the first data, and then the target data sent by the access network device is received. Thus, when the first terminal has a TXOP for a first time period, the first device is an access network device, and the second device is the first terminal and / or the second terminal, it can be ensured that the low-latency data of the access network device can be timely sent to the first terminal and / or the second terminal, improving the user experience in low-latency scenarios.

[0180] Figure 9 FIG. is a schematic flowchart of a data transmission method provided by an embodiment of the present disclosure. The data transmission method is executed by a second device. When the second device is the first terminal and / or the second terminal, as Figure 9 shown, the data transmission method may include the following steps:

[0181] Step 901, when the first terminal has a TXOP for a first time period, the first device is the second terminal, and the second device is an access network device, receive a first message sent by the first device.

[0182] Wherein, the first message is used to indicate target data to be sent by the first device, and the target latency corresponding to the target data is less than a threshold.

[0183] Wherein, the second terminal is a terminal without a TXOP for the first time period.

[0184] It should be noted that since the first terminal has a TXOP for the first time period, the first terminal can send low-latency data or non-low-latency data to the radio access network during the first time period, while the second terminal cannot send low-latency data to the radio access network during the first time period. Therefore, when the second terminal has target data to be sent to the access network device, the second terminal needs to send a first message to the access network device, and the access network device can receive the first message sent by the second terminal.

[0185] Step 902, send a third message to the first terminal and the second terminal.

[0186] It should be noted that the access network device can allocate communication resources only for the second terminal without changing the current communication resources of the first terminal; or can re-allocate communication resources for the first terminal and the second terminal. Therefore, the third message may include the communication resources corresponding to the second terminal, or may also include the communication resources corresponding to the first terminal and the second terminal respectively. The second terminal is a terminal without a TXOP for the first time period.

[0187] Wherein, the third message may be a Trigger Frame.

[0188] Step 903: Receive the target data sent by the first device.

[0189] In the embodiments of the present disclosure, when the first terminal has the TXOP of the first time period, the first device is the second terminal, and the second device is the access network device, the first message sent by the first device is received, then the third message is sent to the first terminal and the second terminal, and finally the target data sent by the first device is received. Thus, when the first terminal has the TXOP of the first time period, the first device is the second terminal, and the second device is the access network device, the low-latency data of the second terminal can be sent to the access network device in time, improving the user experience in the low-latency scenario.

[0190] Figure 10 It is an interaction schematic diagram of a data transmission method provided by an embodiment of the present disclosure. As Figure 10 shown, the first device is a terminal, the second device is an access network device, and the access network device has the TXOP of the first time period. The data transmission method may include the following steps:

[0191] Step 1001: The access network device sends the second data to Terminal 1.

[0192] Step 1002: When Terminal 1 and / or Terminal 2 has target data to be sent to the access network device, send the first message to the access network device.

[0193] Among them, Terminal 1 may send the first message to the access network device through the acknowledgment block BA. Terminal 2 directly sends the first message to the access network device.

[0194] Among them, the first message is used to indicate the target data to be sent by the first device.

[0195] In some embodiments, the first message further includes the description information corresponding to the target data. The description information includes at least one of the following:

[0196] The type of the target data;

[0197] The target latency corresponding to the target data;

[0198] The first transmission priority corresponding to the target data.

[0199] Step 1003: The access network device stops sending the second data to Terminal 1 and sends the second message to Terminal 1 and / or Terminal 2.

[0200] Among them, the second message includes the communication resources corresponding to the terminal.

[0201] In some embodiments, when the access network device determines that the first transmission priority corresponding to the target data is higher than the third transmission priority corresponding to the second data, the access network device sends a second message to terminal 1 and / or terminal 2.

[0202] Step 1004, terminal 1 and / or terminal 2 send the target data to the access network device.

[0203] Step 1005, the access network device sends a fourth message to terminal 1 and / or terminal 2.

[0204] Among them, the fourth message may be a Multi-STA Block ACK message.

[0205] Figure 11 As shown in the interaction schematic diagram of a data transmission method provided by an embodiment of the present disclosure, Figure 11 as shown, the first terminal has a TXOP for the first time period, the first device is the access network device, and the second device is the first terminal and / or the second terminal. The data transmission method may include the following steps:

[0206] Step 1101, the first terminal sends the first data to the access network device.

[0207] Step 1102, the access network device sends a first message and a block acknowledgment BA indicating that the first data has been received to the first terminal and / or the second terminal.

[0208] Among them, the first message is used to indicate the target data to be sent by the first device and is also used to instruct the first terminal to stop sending the first data.

[0209] In some embodiments, when the access network device determines that the first transmission priority corresponding to the target data is higher than the second transmission priority corresponding to the first data, the access network device sends the first message to the first terminal and / or the second terminal.

[0210] Step 1103, the access network device sends the target data to the first terminal and / or the second terminal.

[0211] Step 1104, the first terminal and / or the second terminal send a block acknowledgment BA to the access network device.

[0212] Figure 12 As shown in the interaction schematic diagram of a data transmission method provided by an embodiment of the present disclosure, Figure 12 as shown, the first terminal has a TXOP for the first time period, the first device is the second terminal, and the second device is the access network device. The data transmission method may include the following steps:

[0213] Step 1201, the first terminal sends the first data to the access network device.

[0214] Step 1202: The access network device sends a Multi-STA Block ACK for indicating the reception of the second data to the first terminal and the second terminal.

[0215] Step 1203: The second terminal sends a first message to the access network device.

[0216] Wherein, the first message is used to indicate the target data to be sent by the first device.

[0217] Step 1204: The access network device sends a third message to the first terminal and / or the second terminal.

[0218] Wherein, the third message includes the communication resources corresponding to the second terminal, or includes the communication resources corresponding to the first terminal and the second terminal respectively, and the second terminal is the terminal without a TXOP in the first period.

[0219] Step 1205: The second terminal sends the target data to the access network device.

[0220] In some embodiments, the first terminal may send the first data based on the access network device.

[0221] Step 1206: The access network device sends a fourth message to the first terminal and / or the second terminal.

[0222] Wherein, the fourth message may be a Multi-STA Block ACK for indicating the reception of the target data.

[0223] To implement the above embodiments, the present disclosure also proposes a data transmission device.
