[0047] Figure 3 This is a flowchart illustrating a data frame transmission method according to an exemplary embodiment.

[0048] Figure 4 This is a block diagram illustrating a data frame transmission apparatus according to an exemplary embodiment.

[0049] Figure 5 This is a block diagram illustrating a data frame transmission apparatus according to an exemplary embodiment. Detailed Implementation

[0050] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0051] The data frame transmission method provided in this disclosure is applied to a wireless local area network (WLAN) communication system including a data transmitting device and a data receiving device. The data transmitting device and the data receiving device can be a station (STA) or an access point (AP). Forward and backhaul data transmission is performed between the data transmitting device and the data receiving device via the WLAN.

[0052] In this disclosure, STA can be understood as a user terminal in a wireless local area network. This user terminal can be called User Equipment (UE), Mobile Station (MS), Mobile Terminal (MT), etc., and is a device that provides voice and / or data connectivity to a user. For example, the terminal can be a handheld device with wireless connectivity, an in-vehicle device, etc. Currently, examples of such terminals include: smartphones (MobilePhone), pocket personal computers (PPCs), handheld computers, personal digital assistants (PDAs), laptops, tablets, wearable devices, Internet of Things (IoT) clients, or in-vehicle devices, etc.

[0053] In this disclosure, AP refers to devices such as routers that allow wireless local area network user terminals to access the network.

[0054] In related technologies, STA and AP use the IEEE 802.11 standard for data frame transmission. Currently, IEEE 802.11 has established the SG (study group) IEEE 802.11be to research next-generation mainstream Wi-Fi technology. The research scope includes 320MHz bandwidth transmission, aggregation and coordination of multiple frequency bands, etc., with the proposed vision of improving speed and throughput by at least four times compared to the existing IEEE 802.11ax. Its main application scenarios are video transmission, AR, VR, etc.

[0055] The aggregation and coordination of multiple frequency bands refers to communication simultaneously in multiple frequency bands or multiple bandwidths within the same frequency band, such as communication simultaneously in the 2.4GHz, 5GHz, and 6-7GHz frequency bands. Simultaneous communication in multiple frequency bands or multiple bandwidths within the same frequency band can be understood as multi-connection communication, or multi-link aggregation (MLA).

[0056] Data frames are transmitted under multiple connections. Data frames with the same Quality of Service (QoS) requirements are assigned the same Traffic Identifier (TID), or data frames with the same content and the same Sequence Number (SN) are also assigned the same TID. When a data frame is retransmitted, a retransmission count is performed. For example, a short retransmission count (SSRC) and a long retransmission count (SLRC) are performed.

[0057] In this embodiment of the disclosure, when data frames are transmitted under multiple connections, a clock is set for data frame transmission, and the data frame retransmission count (SSRC and / or SLRC counts) is independent for different connections. For newly transmitted data frames, the initial value of the data frame retransmission count (SSRC and / or SLRC counts) under each connection is set to 0. When a retransmission occurs, the retransmission count value increases sequentially, and the contention window (CW) also increases accordingly. The retransmission count value increases until the CW window reaches its maximum value and then stops increasing, remaining unchanged. It is understood that if the CW window is at its maximum value, but the clock used for data frame transmission has not reached its maximum value, then the data frame retransmission count (SSRC and / or SLRC counts) will no longer increase and will remain unchanged.

[0058] During the transmission of data frames, if the transmission of data frames is switched from one connection to another, how to count the retransmission of data frames needs further research.

[0059] This disclosure provides a data frame transmission method in which, when the transmission of a data frame is switched from a first connection to a second connection, a retransmission count is performed on the data frame in the second connection, thereby realizing the counting of data frame retransmissions when the data frame transmission is switched.

[0060] Figure 1 This is a flowchart illustrating a data frame transmission method according to an exemplary embodiment, such as... Figure 1 As shown, the data frame transmission method is used in a site or access point and includes the following steps.

[0061] In step S11, it is determined that the transmission of the data frame is switched from the first connection to the second connection.

[0062] In this embodiment, data frames are transmitted over multiple connections and can be switched between connections. For ease of description, the connection where the data frame resides before the switch is referred to as the first connection, and the connection where the data frame resides after the switch is referred to as the second connection.

[0063] In step S12, in response to the transmission of data frames, the connection is switched from the first connection to the second connection, and the retransmission count of data frames is performed on the second connection.

[0064] In this embodiment of the disclosure, the retransmission count of data frames on the second connection can be performed in either method one or method two.

[0065] Method 1: On the second connection, the retransmission count of the data frame is set to zero before retransmission counting is performed, and the TID and / or SN are reassigned to the data frame.

[0066] In one embodiment of this disclosure, the retransmission count value of the data frame corresponding to the second connection is set to zero, and the TID and / or SN of the data frame are reassigned to the data frame so as to perform retransmission counting on the data frame on the second connection accordingly.

[0067] In this embodiment of the present disclosure, on the second connection, the retransmission count of the data frame is set to zero before retransmission counting is performed. This can be understood as treating the data frame as a newly transmitted data frame on the second connection for retransmission counting. For example, SSRC and / or SLRC are initialized, the count values ​​of SSRC and / or SLRC are set to zero, and the retransmission of the data frame is recounted on the second connection.

[0068] In this embodiment of the disclosure, when re-counting the retransmission of a data frame on the second connection, the retransmission count value of the data frame is set to zero before retransmission counting is performed, and the TID and / or SN are reassigned to the data frame.

[0069] Furthermore, in this embodiment of the present disclosure, when re-counting the retransmission of data frames on the second connection, the retransmission counting of data frames on the first connection can be terminated.

[0070] In this embodiment of the disclosure, assigning TID and / or SN to a data frame means:

[0071] Assign TID and SN to the data frame; or

[0072] Assign a TID to a data frame, without specifying the method for determining the SN of the data frame; or

[0073] Assign a serial number (SN) to a data frame, without specifying how the TID of the data frame is determined.

[0074] In this embodiment of the disclosure, TID and / or SN can be reallocated for data frames. That is, when reallocation is performed to reallocate TID and / or SN for data frames, it refers to the TID and SN reallocated for data frames transmitted on the second connection. Alternatively, when reallocation is performed to reallocate TID and / or SN for data frames, it refers to the TID reallocated for data frames transmitted on the second connection; and the method of determining the SN of the second connection is not limited. Alternatively, when reallocation is performed to reallocate TID and / or SN for data frames, it refers to the SN reallocated for data frames transmitted on the second connection; and the method of determining the TID of the second connection is not limited.

[0075] Of course, the above embodiments are merely illustrative examples of the technical solutions of the present disclosure and are not intended to limit the scope of protection of the present disclosure.

[0076] In this embodiment of the disclosure, the recounting of data frame retransmissions may be re-performed on the second connection when the clock used for data frame transmission fails, or when the clock used for data frame transmission fails and the CW window is at its maximum value. This can be understood as follows: when performing the retransmission count for data frames on the second connection using method one, this can be done when it is determined that the clock used for data frame transmission has failed, or when it is determined that the clock used for data frame transmission has failed and the CW window is at its maximum value.

[0077] Figure 2 This is a flowchart illustrating a data frame transmission method according to an exemplary embodiment, such as... Figure 2 As shown, the data frame transmission method is used in a site or access point and includes the following steps.

[0078] In step S21, it is determined that the clock used for data frame transmission is faulty, or it is determined that the clock used for data frame transmission is faulty and the CW window is at its maximum value.

[0079] In step S22, the retransmission count of data frames on the first connection is terminated, and the clock for transmitting the data frames is activated.

[0080] In step S23, the retransmission count value of the data frame corresponding to the second connection is set to zero, and the TID and / or SN are reassigned to the data frame so as to count the retransmission of the data frame on the second connection accordingly.

[0081] In this embodiment of the disclosure, when the transmission of a data frame switches from the first connection to the second connection, the data frame retransmission count is restarted on the second connection, enabling the counting of data frame retransmissions when the data frame transmission switches. Furthermore, the counting of data frame retransmissions is also implemented in the event of a clock failure in the first connection.

[0082] Method 2: On the second connection, the retransmission count value of the data frame on the first connection is used as the initial value for retransmission counting, and the TID and / or SN already allocated in the first connection are continued to be used.

[0083] In one embodiment of this disclosure, when retransmission counts of data frames on the first connection are continued to be performed on the second connection, the retransmission count value corresponding to the data frame on the first connection can be used as the initial value for the retransmission count value corresponding to the data frame on the second connection, so as to perform retransmission counts on the data frame on the second connection. Further, in a second embodiment of this disclosure, the TID and / or SN corresponding to the data frame on the first connection are continued to be used as the corresponding TID and / or SN on the second connection.

[0084] In this embodiment of the disclosure, when the clock used for data frame transmission is valid, or when the CW window for retransmission counting of data frames on the first connection is at its maximum value, the second method is adopted to continue using the retransmission count value on the first connection for data frame retransmission counting. For example, if a data frame transmission switch occurs, when it is determined that the clock used for data frame transmission is valid, or when it is determined that the CW window for retransmission counting of data frames on the first connection is at its maximum value, on the second connection, the retransmission count value of the data frame corresponding to the first connection is used as the initial value of the retransmission count value of the data frame corresponding to the second connection, so as to perform retransmission counting of the data frame on the second connection, and continue to use the TID and / or SN already allocated in the first connection.

[0085] In this embodiment of the disclosure, assigning TID and / or SN to a data frame means:

[0086] Assign TID and SN to the data frame; or

[0087] Assign a TID to a data frame, without specifying the method for determining the SN of the data frame; or

[0088] Assign a serial number (SN) to a data frame, without specifying how the TID of the data frame is determined.

[0089] In the embodiments of this disclosure, the TID and / or SN corresponding to the first connection of the data frame can continue to be used as the corresponding TID and / or SN of the second connection. That is, when the TID and SN of the data frame corresponding to the first connection continue to be used, the TID and SN of the first connection continue to be used as the TID and SN of the second connection. Or, when the TID of the data frame corresponding to the first connection continues to be used, the TID of the first connection is used as the initial value of the TID of the second connection; and the method of determining the SN of the second connection is not limited. Or, when the SN of the data frame corresponding to the first connection continues to be used, the SN of the first connection is used as the initial value of the SN of the second connection; and the method of determining the TID of the second connection is not limited.

[0090] Of course, the above embodiments are merely illustrative examples of the technical solutions of the present disclosure and are not intended to limit the scope of protection of the present disclosure.

[0091] In this embodiment of the disclosure, the TID already assigned in the first connection is used as the identifier of the retransmitted data frame. For further identification, the SN number (single data frame and consecutive data frame) can also be carried. If it is a consecutive data frame, the identifier assigned to the consecutive data frame can be carried, for example, the identifier assigned to the consecutive data frame can be carried in the position of the SN.

[0092] Figure 3 This is a flowchart illustrating a data frame transmission method according to an exemplary embodiment, such as... Figure 3 As shown, the data frame transmission method is used in a site or access point and includes the following steps.

[0093] In step S31, it is determined that the clock used for data frame transmission is valid, or the CW window for retransmission counting of data frames on the first connection is determined to be at its maximum value.

[0094] In step S32, the retransmission count value corresponding to the first connection of the data frame is used as the initial value of the retransmission count value corresponding to the second connection of the data frame, so as to count the retransmission of the data frame on the second connection and continue to use the TID and / or SN allocated in the first connection.

[0095] In this embodiment of the disclosure, when the transmission of a data frame is switched from the first connection to the second connection, the retransmission count value of the data frame corresponding to the first connection is continued to be used on the second connection to count the retransmission of the data frame, which can realize the counting of data frame retransmissions when the data frame transmission is switched.

[0096] It is understood that in the above embodiments of this disclosure, when the transmission of data frames under multiple connections switches from the first connection to the second connection, and the retransmission count of data frames is performed on the second connection, if the CW window reaches its maximum value on the first connection, but the clock for transmitting data frames remains valid and has not reached its maximum value, the CW window can be initialized on the second connection, and the retransmission count value can be increased one by one when a data frame is retransmitted, until the CW window reaches its maximum value.

[0097] It can be further understood that the retransmission counting process involved in the embodiments of this disclosure can be a retransmission counting process for SSRC and / or SLRC, and the retransmission count value can be the SSRC count value or the SLRC count value. This can be understood as follows: under multiple connections, if a data frame is retransmitted, the SSRC count value and / or SLRC count value increases sequentially.

[0098] It can be further understood that, in this embodiment of the present disclosure, if the clock used for transmitting data frames fails, when the transmission of data frames is switched, Method 1 is adopted: the SSRC count value and / or SLRC count value are initialized, the CW window is initialized, and the clock used for transmitting data frames is reactivated to count the retransmission of data frames on the second connection. If the clock used for transmitting data frames is valid, Method 2 is adopted: the CW window is initialized, the SRC count value and / or SLRC count value corresponding to the data frame in the first connection is used as the initial value of the retransmission count value corresponding to the data frame in the second connection, and the clock used for transmitting data frames continues to be used to count the retransmission of data frames on the second connection.

[0099] It can be further understood that, in the embodiments of this disclosure, assigning TID and / or SN to a data frame means:

[0100] Assign TID and SN to the data frame; or

[0101] Assign a TID to a data frame, without specifying the method for determining the SN of the data frame; or

[0102] Assign a serial number (SN) to a data frame, without specifying how the TID of the data frame is determined.

[0103] In all embodiments of this disclosure, the TID and / or SN corresponding to the first connection can continue to be used as the corresponding TID and / or SN of the second connection. That is, when the TID and SN of the first connection are continued to be used, the TID and SN of the first connection are continued to be used as the TID and SN of the second connection. Or, when the TID of the first connection is continued to be used, the TID of the first connection is used as the initial value of the TID of the second connection; and the method of determining the SN of the second connection is not limited. Or, when the SN of the first connection is continued to be used, the SN of the first connection is used as the initial value of the SN of the second connection; and the method of determining the TID of the second connection is not limited.

[0104] In all embodiments of this disclosure, TID and / or SN can be reallocated for data frames. That is, when reallocation is performed to reallocate TID and / or SN for data frames, it refers to the TID and SN reallocated for data frames transmitted on the second connection. Alternatively, when reallocation is performed to reallocate TID and / or SN for data frames, it refers to the TID reallocated for data frames transmitted on the second connection; and the method of determining the SN of the second connection is not limited. Alternatively, when reallocation is performed to reallocate TID and / or SN for data frames, it refers to the SN reallocated for data frames transmitted on the second connection; and the method of determining the TID of the second connection is not limited.

[0105] Of course, the above embodiments are merely illustrative examples of the technical solutions of the present disclosure and are not intended to limit the scope of protection of the present disclosure.

[0106] In one embodiment of this disclosure, if the data frame transmission is successful, the retransmission count is initialized to zero. In another embodiment, if the data frame transmission is successful, the data frame transmission clock can be reset to zero.

[0107] Based on the same concept, embodiments of this disclosure also provide a data frame transmission apparatus.

[0108] It is understood that the data frame transmission apparatus provided in this disclosure includes hardware structures and / or software modules corresponding to each function in order to achieve the above-mentioned functions. In conjunction with the units and algorithm steps of the various examples disclosed in this disclosure, this disclosure can be implemented in hardware or a combination of hardware and computer software. Whether a function is executed by hardware or by computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of the technical solutions of this disclosure.
