[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present disclosure and do not represent all of the embodiments. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present disclosure without inventive effort are within the scope of protection of the present disclosure.

[0047] The embodiments of the present disclosure provide a wireless frame transmission method, an electronic device, and a storage medium, which are used to provide a transmission mechanism that supports preemption resources to achieve the transmission of non-periodic low-latency services.

[0048] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0049] As shown in Figure 1, an embodiment of the present disclosure provides a wireless frame transmission method. Optionally, the method can be applied to a transmitting end, which can be a station device (STA) or an access point (AP) device. For ease of explanation, the transmitting end is taken as an STA as an example, but this does not constitute a limitation of the embodiment of the present disclosure.

[0050] The method may include the following steps:

[0051] Step 101: Send a radio frame, where the radio frame includes non-low-latency service data and low-latency service data;

[0052] The low-latency service data is transmitted between two MSDUs of the A-MSDU of the non-low-latency service data;

[0053] The life cycle parameters of the A-MSDU include: a first parameter or a second parameter;

[0054] The first parameter includes a preset life cycle parameter of the non-low-latency service data;

[0055] The second parameter includes the sum of the preset life cycle parameter and the transmission duration of the low-latency service data.

[0056] Optionally, in an embodiment of the present disclosure, the AP is, for example, a device with a wireless to wired bridging function, and the AP is responsible for extending the services provided by the wired network to the wireless network; the STA is, for example, an electronic device with a wireless network access function, and provides a frame delivery service to enable information to be transmitted.

[0057] In a wireless local area network (WLAN), a Basic Service Set (BSS) can be composed of an AP and one or more stations (STAs) communicating with the AP. A Basic Service Set can be connected to a Distribution System (DS) through its AP, and then connected to another Basic Service Set to form an Extended Service Set (ESS). As a first example, referring to Figure 2, AP1 and STA1 form BSS1, and AP2 and STA2 form BSS2. If the coverage of two or more BSSs overlap, an Overlapping Basic Service Set (BSS, OBSS) is formed. As shown in Figure 2, BSS1 and BSS2 overlap to form an OBSS.

[0058] Optionally, in an embodiment of the present disclosure, the AP and STA may be devices supporting multiple connections, for example, they may be represented as AP MLD and non-AP MLD, respectively; the AP MLD may represent an access point supporting multiple connection communication functions, and the non-AP MLD may represent a station supporting multiple connection communication functions.

[0059] Referring to Figure 3, the AP MLD may include three subordinate APs, such as AP1, AP2, and AP3 as shown in Figure 3; each AP may operate in connection 1, connection 2, and connection 3 respectively; the non-AP MLD may also include three subordinate STAs, such as STA1, STA2, and STA3 as shown in Figure 2; STA1 operates in connection 1, STA2 operates in connection 2, and STA3 operates in connection 3.

[0060] For ease of description, the following mainly describes an example in which an AP communicates with a STA under multiple connections. However, the example embodiments of the present disclosure are not limited to this. In the example of Figure 3, it is assumed that AP1 communicates with STA1 through the corresponding first connection Link 1. Similarly, AP2 communicates with STA2 through the corresponding second connection Link 2, and the AP communicates with STA3 through the third connection Link 3. In addition, Link 1 to Link 3 can be multiple connections at different frequencies, for example, connections at 2.4 GHz, 5 GHz, and 6 GHz, or several connections with the same or different bandwidths at 2.4 GHz. In addition, multiple channels can exist under each connection. It will be understood that the communication scenario shown in Figure 2 is only exemplary, and the concept of the present disclosure is not limited to this. For example, the AP MLD can be connected to multiple (for example, three) non-AP MLDs, or under each connection, the AP can communicate with multiple other types of stations.

[0061] In UHR, for bursty low-latency services (low latency), preemption of resources can be used for transmission. The transmitter sends a wireless frame, which includes non-low-latency service data and low-latency service data, and the low-latency service data is transmitted between two MSDUs of the aggregation of the MSDUs (A-MSDU) of the non-low-latency service data; that is, between the two MSDUs of the same A-MSDU, the low-latency service is transmitted by preempting transmission resources to ensure the transmission efficiency of the low-latency service. The two MSDUs of the same A-MSDU can be two adjacent MSDUs or the same MSDU. For example, when transmitting MSDU1, the transmission resources are preempted to transmit the low-latency service, and MSDU1 is retransmitted after the low-latency service transmission is completed. At this time, when transmitting low-latency services, the transmission timer of non-low-latency services pauses counting, and the duration of the lifecycle parameter (lifetime) of the non-low-latency services needs to be added to the transmission duration of the low-latency services, or the transmission duration and retransmission duration of the non-low-latency services.

[0062] Among them, MSDU is the Media Access Control Service Data Unit (MSDU) of the media access control layer.

[0063] For example, as a second example, referring to FIG. 5 , MSDU-STA1 represents an MSDU sent to receiver 1 ( STA1 ), and MSDU-STA2 represents an MSDU sent to receiver 2 ( STA2 ).

[0064] The sending end transmits A-MSDU. During the transmission of MSDU-STA1 of the non-low-latency service, if the sending end has a low-latency service to transmit, it seizes the resources of A-MSDU of the non-low-latency service for transmission, that is, transmits MSDU-STA2; after the data transmission of the low-latency service is completed, the non-low-latency service MSDU-STA1 is transmitted.

[0065] Thus, the lifecycle parameter (lifetime) of the A-MSDU includes: the first parameter or the second parameter;

[0066] The first parameter includes the preset life cycle parameter of the non-low-latency service data, that is, the life cycle parameter of the A-MSDU is a fixed value; for example, a fixed lifetime is set for the A-MSDU of the non-low-latency service data, then even if the data transmission resources for transmitting the non-low-latency service are forcibly occupied to transmit the low-latency service, the preset life cycle parameter of the non-low-latency service data is still a fixed lifetime. In addition, the transmitting end originally seizes the transmission opportunity (TXOP) belonging to the current moment in order to transmit the non-low-latency service, and when the low-latency service is transmitted in this seized TXOP; for the non-low-latency service data, the lifetime of its MSDU (or A-MSDU) is fixed, then when the low-latency service is transmitted, the transmit timer of the non-low-latency service data stops counting.

[0067] The second parameter includes the sum of the preset lifecycle parameter and the transmission duration of the low-latency service data; that is, the lifecycle parameter of the A-MSDU is the preset lifetime duration plus the transmission duration of the low-latency service data. At this time, when transmitting low-latency service data, the transmit timer of non-low-latency service data is also counted; and both the receiving end and the sending end understand that the lifetime of their non-low-latency service data has been added with the transmission duration of the low-latency service (or the sum of the transmission duration and retransmission duration of the low-latency service).

[0068] In an embodiment of the present disclosure, when the transmitting end transmits a low-latency service by preempting transmission resources, the lifecycle parameter of the non-low-latency service includes: a first parameter or a second parameter; the first parameter includes a preset lifecycle parameter of the non-low-latency service data; the second parameter includes the sum of the preset lifecycle parameter and the transmission duration of the low-latency service data. An embodiment of the present disclosure provides a method for determining the lifecycle parameter of a non-low-latency service to support the transmission mechanism of preemption resources and realize the transmission of non-periodic low-latency services.

[0069] An embodiment of the present disclosure provides a wireless frame transmission method. Optionally, the method may be applied to a transmitting end. The method may include the following steps:

[0070] The first MSDU of an A-MSDU that sends non-low-latency service data;

[0071] Sending low-latency service data and determining the remaining lifecycle duration in the lifecycle parameters of the A-MSDU;

[0072] The life cycle parameters of the A-MSDU include: a first parameter or a second parameter;

[0073] The first parameter includes a preset life cycle parameter of the non-low-latency service data;

[0074] The second parameter includes the sum of the preset life cycle parameter and the transmission duration of the low-latency service data.

[0075] It can be understood that the first MSDU is non-low-latency service data transmitted before the low-latency service, and after the low-latency service data transmission is completed, the first MSDU may be retransmitted.

[0076] After sending the low-latency service data, the sending end can determine the remaining life cycle duration in the life cycle parameter of the A-MSDU, and the remaining life cycle duration can be determined based on the life cycle parameter of the entire A-MSDU; for example, when the life cycle parameter of the entire A-MSDU is the first parameter, the first parameter is a fixed value, and it can be determined based on the remaining duration of the duration corresponding to the first parameter at the current moment; for example, the first parameter is 1ms (milliseconds), and after the low-latency service data is transmitted, 0.8ms has passed from 1ms, and the remaining life cycle duration is 0.2ms.

[0077] For example, when the life cycle parameter of the entire A-MSDU is the second parameter, the second parameter needs to take into account the transmission duration of the low-latency service data; for example, the preset life cycle parameter of the A-MSDU is 1ms (millisecond). After the low-latency service data is transmitted, 0.8ms of the 1ms has passed, and the transmission duration of the low-latency service data is 0.1ms. The remaining life cycle duration is 0.2ms+0.1ms, that is, 0.3ms.

[0078] An embodiment of the present disclosure provides a wireless frame transmission method. Optionally, the method may be applied to a transmitting end. The method may include the following steps:

[0079] The first MSDU of an A-MSDU that sends non-low-latency service data;

[0080] Send low-latency service data, retransmit the first MSDU, and determine the remaining lifecycle duration in the lifecycle parameter of the A-MSDU;

[0081] The life cycle parameters of the A-MSDU include: a first parameter or a second parameter;

[0082] The first parameter includes a preset life cycle parameter of the non-low-latency service data;

[0083] The second parameter includes the sum of the preset life cycle parameter and the transmission duration of the low-latency service data.

[0084] The first MSDU is non-low-latency service data transmitted before the low-latency service. After the low-latency service data is transmitted, the first MSDU can be retransmitted to avoid incomplete transmission of the first MSDU.

[0085] An embodiment of the present disclosure provides a wireless frame transmission method. Optionally, the method may be applied to a transmitting end. The method may include the following steps:

[0086] The first MSDU of an A-MSDU that sends non-low-latency service data;

[0087] Send low-latency service data, retransmit the first MSDU, and determine the remaining lifecycle duration in the lifecycle parameter of the A-MSDU;

[0088] The life cycle parameters of the A-MSDU include: a first parameter or a second parameter;

[0089] The first parameter includes a preset life cycle parameter of the non-low-latency service data;

[0090] The second parameter includes: the sum of the preset life cycle parameter, the transmission duration of the low-latency service data, and the retransmission duration of retransmitting the first MSDU.

[0091] Among them, the first MSDU is non-low-latency service data transmitted before the low-latency service. After the low-latency service data is transmitted, the first MSDU can be retransmitted to avoid the first MSDU from being incompletely transmitted. In the case of retransmitting the first MSDU, the life cycle parameter of the A-MSDU can be added with the retransmission duration consumed by retransmitting the first MSDU. Correspondingly, the remaining life cycle duration must also be added with the retransmission duration. For example, the preset life cycle parameter of the A-MSDU is 1ms (millisecond). After the low-latency service data is transmitted, 0.8ms of the 1ms has passed, and the transmission duration of the low-latency service data is 0.1ms. It takes 0.1ms to retransmit the first MSDU, so the remaining life cycle duration is 0.2ms+0.1ms+0.1ms, that is, 0.4ms.

[0092] Optionally, in an embodiment of the present disclosure, during the process of sending the low-latency service data, the sending end suspends the counting of the transmission timer of the non-low-latency service data; for the counting of the transmission timer (transmit timer) of the remaining non-low-latency service of the preempted resources, it is suspended when the low-latency service is transmitted, and starts counting when the non-low-latency service is retransmitted, so as to ensure that the transmission timer is consistent with the actual transmission situation of the non-low-latency service.

[0093] An embodiment of the present disclosure provides a wireless frame transmission method, applied to a transmitting end, the method comprising:

[0094] Sending a radio frame, where the radio frame includes non-low-latency service data and low-latency service data;

[0095] The low-latency service data is transmitted between two MSDUs of the A-MSDU of the non-low-latency service data;

[0096] The life cycle parameters of the A-MSDU include: a first parameter or a second parameter;

[0097] The first parameter includes a preset life cycle parameter of the non-low-latency service data;

[0098] The second parameter includes the sum of the preset life cycle parameter and the transmission duration of the low-latency service data.

[0099] In an optional embodiment, the sending of the wireless frame includes:

[0100] Sending a first MSDU of the A-MSDU;

[0101] The low-latency service data is sent, and the remaining life cycle duration in the life cycle parameter is determined.

[0102] In an optional embodiment, after sending the low-latency service data, the method further includes:

[0103] Retransmit the first MSDU.

[0104] In an optional embodiment, the second parameter includes: the sum of the preset life cycle parameter, the transmission duration of the low-latency service data, and the retransmission duration of retransmitting the first MSDU.

[0105] In an optional embodiment, the sending the low-latency service data includes:

[0106] Pause the counting of the transmission timer of the non-low-latency service data.

[0107] In an embodiment of the present disclosure, when the transmitting end transmits a low-latency service by preempting transmission resources, the lifecycle parameter of the non-low-latency service includes: a first parameter or a second parameter; the first parameter includes a preset lifecycle parameter of the non-low-latency service data; the second parameter includes the sum of the preset lifecycle parameter and the transmission duration of the low-latency service data. An embodiment of the present disclosure provides a method for determining the lifecycle parameter of a non-low-latency service to support the transmission mechanism of preemption resources and realize the transmission of non-periodic low-latency services.

[0108] Referring to Figure 6, an embodiment of the present disclosure provides a wireless frame transmission method. Optionally, the method can be applied to a receiving end, and the receiving end can be a station device (Station, STA) access point or (Access Point, AP) device; for ease of explanation, the receiving end is taken as an STA as an example, but this does not constitute a limitation of the embodiment of the present disclosure.

[0109] The method may include the following steps:

[0110] Step 601: Receive a radio frame sent by a transmitting end, where the radio frame includes non-low-latency service data and low-latency service data;

[0111] The low-latency service data is transmitted between two MSDUs of the A-MSDU of the non-low-latency service data;

[0112] The life cycle parameters of the A-MSDU include: a first parameter or a second parameter;

[0113] The first parameter includes a preset life cycle parameter of the non-low-latency service data;

[0114] The second parameter includes the sum of the preset life cycle parameter and the transmission duration of the low-latency service data.

[0115] The architecture of the WLAN to which the wireless frame transmission method provided in the embodiment of the present disclosure is applied refers to the aforementioned first example and will not be described in detail here.

[0116] In UHR, for bursty low-latency services (low latency), the transmitter can use preemption resources for transmission. The receiving end wireless frame includes non-low-latency service data and low-latency service data, and the low-latency service data is transmitted between two MSDUs of the aggregation of the MSDUs (A-MSDU) of the non-low-latency service data; that is, between the two MSDUs of the same A-MSDU, the transmitter uses preemption transmission resources to transmit low-latency services to ensure the transmission efficiency of low-latency services. The two MSDUs of the same A-MSDU can be two adjacent MSDUs or the same MSDU. For example, when transmitting MSDU1, the transmission resources are preempted to transmit low-latency services, and MSDU1 is retransmitted after the low-latency service transmission is completed. At this time, when transmitting low-latency services, the transmission timer of non-low-latency services pauses counting, and the duration of the lifecycle parameter (lifetime) of the non-low-latency services needs to be added to the transmission duration of the low-latency services, or the transmission duration and retransmission duration of the non-low-latency services.

[0117] For example, as a second example, referring to FIG. 5 , MSDU-STA1 represents an MSDU sent to receiver 1 ( STA1 ), and MSDU-STA2 represents an MSDU sent to receiver 2 ( STA2 ).

[0118] The sending end transmits A-MSDU. During the transmission of MSDU-STA1 of the non-low-latency service, if the sending end has a low-latency service to transmit, it seizes the resources of A-MSDU of the non-low-latency service for transmission, that is, transmits MSDU-STA2; after the data transmission of the low-latency service is completed, the non-low-latency service MSDU-STA1 is transmitted.

[0119] In this way, when the receiving end receives non-low-latency service data, the lifecycle parameter (lifetime) of the A-MSDU of the non-low-latency service data includes: the first parameter or the second parameter;

[0120] The first parameter includes the preset life cycle parameter of the non-low-latency service data, that is, the life cycle parameter of the A-MSDU is a fixed value; for example, a fixed lifetime is set for the A-MSDU of the non-low-latency service data, then even if the data transmission resources for transmitting the non-low-latency service are forcibly occupied to transmit the low-latency service, the preset life cycle parameter of the non-low-latency service data is still a fixed lifetime. In addition, the transmitting end originally seizes the transmission opportunity (TXOP) belonging to the current moment in order to transmit the non-low-latency service, and when the low-latency service is transmitted in this seized TXOP; for the non-low-latency service data, the lifetime of its MSDU (or A-MSDU) is fixed, then when the low-latency service is transmitted, the transmit timer of the non-low-latency service data stops counting.

[0121] The second parameter includes the sum of the preset lifecycle parameter and the transmission duration of the low-latency service data; that is, the lifecycle parameter of the A-MSDU is the preset lifetime duration plus the transmission duration of the low-latency service data. At this time, when transmitting low-latency service data, the transmit timer of non-low-latency service data is also counted; and both the receiving end and the sending end understand that the lifetime of their non-low-latency service data has been added with the transmission duration of the low-latency service (or the sum of the transmission duration and retransmission duration of the low-latency service).

[0122] In an embodiment of the present disclosure, when the transmitting end transmits a low-latency service by preempting transmission resources, and the receiving end receives non-low-latency service data, the lifecycle parameters of the non-low-latency service include: a first parameter or a second parameter; the first parameter includes a preset lifecycle parameter of the non-low-latency service data; the second parameter includes the sum of the preset lifecycle parameter and the transmission duration of the low-latency service data. An embodiment of the present disclosure provides a method for determining the lifecycle parameters of a non-low-latency service to support the transmission mechanism of preemption resources and realize the transmission of non-periodic low-latency services.

[0123] An embodiment of the present disclosure provides a wireless frame transmission method. Optionally, the method may be applied to a receiving end. The method may include the following steps:

[0124] Receiving a first MSDU of an A-MSDU of non-low-latency service data sent by the transmitting end;

[0125] Receiving the low-latency service data sent by the sending end, and determining the remaining life cycle duration in the life cycle parameter;

[0126] The life cycle parameters of the A-MSDU include: a first parameter or a second parameter;

[0127] The first parameter includes a preset life cycle parameter of the non-low-latency service data;

[0128] The second parameter includes the sum of the preset life cycle parameter and the transmission duration of the low-latency service data.

[0129] It can be understood that the first MSDU is non-low-latency service data transmitted before the low-latency service, and after the low-latency service data transmission is completed, the first MSDU may be retransmitted.

[0130] After the transmitting end sends the low-latency service data, the receiving end can determine the remaining life cycle duration in the life cycle parameter of the A-MSDU, and the remaining life cycle duration can be determined based on the life cycle parameter of the entire A-MSDU; for example, when the life cycle parameter of the entire A-MSDU is the first parameter, the first parameter is a fixed value, and the receiving end can determine it based on the remaining duration of the duration corresponding to the first parameter at the current moment; for example, the first parameter is 1ms (milliseconds), and after the low-latency service data is transmitted, 0.8ms has passed from 1ms, and the remaining life cycle duration is 0.2ms.

[0131] For example, when the life cycle parameter of the entire A-MSDU is the second parameter, the second parameter needs to take into account the transmission duration of the low-latency service data; for example, the preset life cycle parameter of the A-MSDU is 1ms (millisecond). After the sending end transmits the low-latency service data, 0.8ms of the 1ms has passed, and the transmission duration of the low-latency service data is 0.1ms. The remaining life cycle duration is 0.2ms+0.1ms, that is, 0.3ms.

[0132] An embodiment of the present disclosure provides a wireless frame transmission method. Optionally, the method may be applied to a receiving end. The method may include the following steps:

[0133] Receiving a first MSDU of an A-MSDU of non-low-latency service data sent by the transmitting end;

[0134] receiving low-latency service data sent by the transmitting end, receiving the first MSDU retransmitted by the transmitting end, and determining the remaining life cycle duration in the life cycle parameter;

[0135] The life cycle parameters of the A-MSDU include: a first parameter or a second parameter;

[0136] The first parameter includes a preset life cycle parameter of the non-low-latency service data;

[0137] The second parameter includes the sum of the preset life cycle parameter and the transmission duration of the low-latency service data.

[0138] The first MSDU is non-low-latency service data transmitted before the low-latency service. After the low-latency service data transmission is completed, the sending end can retransmit the first MSDU, and the receiving end receives the first MSDU retransmitted by the sending end to avoid the first MSDU from being incompletely transmitted.

[0139] An embodiment of the present disclosure provides a wireless frame transmission method. Optionally, the method may be applied to a receiving end. The method may include the following steps:

[0140] Receiving a first MSDU of an A-MSDU of non-low-latency service data sent by the transmitting end;

[0141] receiving low-latency service data sent by the transmitting end, receiving the first MSDU retransmitted by the transmitting end, and determining the remaining life cycle duration in the life cycle parameter;

[0142] The life cycle parameters of the A-MSDU include: a first parameter or a second parameter;

[0143] The first parameter includes a preset life cycle parameter of the non-low-latency service data;

[0144] The second parameter includes the sum of the preset life cycle parameter, the transmission duration of the low-latency service data, and the retransmission duration of retransmitting the first MSDU.

[0145] Among them, the first MSDU is non-low-latency service data transmitted before the low-latency service. After the low-latency service data is transmitted, the transmitter can retransmit the first MSDU to avoid the first MSDU from being incompletely transmitted. In the case of retransmitting the first MSDU, the life cycle parameter of the A-MSDU can be added with the retransmission duration consumed by retransmitting the first MSDU. Correspondingly, the remaining life cycle duration must also be added with the retransmission duration. For example, the preset life cycle parameter of the A-MSDU is 1ms (millisecond). After the transmitter transmits the low-latency service data, 0.8ms of the 1ms has passed, and the transmission duration of the low-latency service data is 0.1ms. It takes 0.1ms to retransmit the first MSDU, so the remaining life cycle duration is 0.2ms+0.1ms+0.1ms, that is, 0.4ms.

[0146] Optionally, in the embodiment of the present disclosure, the receiving the low-latency service data sent by the transmitting end includes:

[0147] Pause the counting of the transmission timer of the non-low-latency service data.

[0148] For the counting of the transmission timer (transmit timer) of the remaining non-low-latency services of the preempted resources, the receiving end controls the transmission timer to pause when transmitting low-latency services, and starts counting when the non-low-latency services are retransmitted to ensure that the transmission timer is consistent with the actual transmission status of the non-low-latency services.

[0149] An embodiment of the present disclosure provides a wireless frame transmission method, applied to a receiving end, the method comprising:
