[0038] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0039] The embodiments of the present disclosure provide a QoS data frame transmission method, an electronic device, and a storage medium, which are used to provide a QoS data frame transmission method.

[0040] 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.

[0041] Referring to Figure 1, Figure 1 illustrates one of the application scenarios of the QoS data frame transmission method provided by various embodiments of the present disclosure. Optionally, a station device (STA), such as an electronic device with wireless network access capabilities, provides a frame delivery service to enable information transmission. An access point (AP), such as a device with wireless to wired bridging capabilities, is responsible for extending the services provided by the wired network to the wireless network.

[0042] In Figure 1, taking QoS data as uplink data as an example, the transmitter is a STA and the receiver is a second AP (AP2). As shown in 101 to 102, when the STA is communicating with the first AP (AP1), it may need to switch to the second AP (AP2). For example, if the communication status between AP1 and the STA is poor, seamless switching to AP2 for communication can ensure uninterrupted data transmission.

[0043] During the handover process, QoS data may be retransmitted. Since QoS data frames do not require Block Ack (BA) message frame confirmation, transmission parameters are required to confirm the transmission of QoS data.

[0044] Optionally, in an embodiment of the present disclosure, the transmission parameter may be, for example, a retry count of the QoS data frame, a MAC Service Data Unit (MSDU) timer count, and / or a lifetime of the QoS data frame. The retry count represents the number of retransmissions of the QoS data frame. For example, for a QoS data frame, a preset retransmission count threshold is 5. When the retry count does not reach 5, AP2 caches the received QoS data. When the retry count reaches 5, AP2 may discard the cached QoS data.

[0045] The MSDU timer counts, for example, when the MSDU is delivered to the Media Access Control (MAC) layer. For example, if the MSDU timer count threshold is the value specified in the dot11 EDCA Table MSDU Lifetime parameter, if the transmit MSDU timer reaches the dot11 EDCA Table MSDU Lifetime, the MSDU (QoS data) or undelivered MSDU segments will be discarded.

[0046] The lifetime of the QoS data frame, for example, records the duration of the existence of the QoS data frame. For example, if the lifetime of the QoS data frame is 50 milliseconds, the sending timing starts from the QoS data frame. If the lifetime of the QoS data frame is exceeded, AP2 can discard the cached QoS data.

[0047] In 103, the STA sends uplink retransmission QoS data, and the SN (sequence number) of the retransmission QoS data remains unchanged.

[0048] In step 104, AP2 receives the uplink retransmission QoS data and first determines the transmission parameters of the uplink retransmission QoS data. Specifically, there are two cases for determining the transmission parameters:

[0049] 1041, transmission parameter accumulation STA transmission parameter 1 before switching from AP1 to AP2;

[0050] 1042, the transmission parameters are cleared and the counting is restarted.

[0051] In step 1041, the transmission parameter 1 is calculated starting from when the STA sends the QoS data to the AP 1. The AP 1 may send the transmission parameter 1 to the AP 2 via a signaling message.

[0052] For example, the MSDU timer is calculated from the time the STA sends QoS data to AP1. If the MSDU timer exceeds the dot11 EDCA Table MSDU Lifetime or the dot11 QAP EDCA Table MSDU Lifetime, AP2 discards the QoS data. The number of retries accumulates from the time the data is sent to AP1. The lifetime of the QoS data frame also starts from the time the STA sends the QoS data to AP1.

[0053] In 1042, the transmission parameters are reset and counted again. That is, the MSDU timer is reset and counted again from the time the STA sends the QoS data to AP2; the number of retry times is reset and counted again from the time the STA sends the QoS data to AP2; and the lifetime of the QoS data frame is also reset and counted again from the time the STA sends the QoS data to AP2.

[0054] Subsequently, AP2 receives the uplink retransmission QoS data based on the transmission parameters; as shown in 1051, the transmission parameters do not reach the threshold, and the uplink retransmission QoS data is received. For example, the number of retransmissions does not exceed the preset retransmission number threshold, the MSDU timer count does not exceed the preset timer count threshold, and the lifetime of the QoS data frame does not exceed the lifetime threshold, and the QoS data frame is received and cached.

[0055] 1052. If the transmission parameter reaches the threshold, the uplink retransmission QoS data corresponding to the SN is discarded, for example, in at least one of the following situations: the number of retransmissions exceeds the preset retransmission threshold, the MSDU timer count exceeds the preset timer count threshold, and the lifetime of the QoS data frame does not exceed the lifetime threshold, then the QoS data frame is discarded.

[0056] In Figure 2, using QoS data as downlink data as an example, the transmitter is AP2 and the receiver is an STA. As shown in steps 201 to 202, when the STA is communicating with the first AP (AP1), it may need to switch to the second AP (AP2). In step 203, AP2 retransmits the downlink QoS data, and the SN (sequence number) of the retransmitted QoS data remains unchanged.

[0057] In 204, the STA receives the downlink retransmission QoS data and first determines the transmission parameters of the downlink retransmission QoS data. Specifically, the determination of the transmission parameters is divided into two cases:

[0058] 2041, transmission parameter accumulation STA transmission parameter 1 before switching from AP1 to AP2;

[0059] 2042, transmission parameters are cleared and counted again.

[0060] In step 2041, the transmission parameter 1 is calculated starting from the time when AP1 sends the QoS data to the STA. AP1 may send the transmission parameter 1 to AP2 via a signaling message.

[0061] For example, the MSDU timer is calculated from the time AP1 sends QoS data to the STA. If the MSDU timer exceeds the dot11 EDCA Table MSDU Lifetime or the dot11 QAP EDCA Table MSDU Lifetime, AP2 discards the QoS data. The number of retries is accumulated from the time AP1 sends the QoS data to the STA. The lifetime of the QoS data frame is also calculated from the time AP1 sends the QoS data to the STA.

[0062] As shown in 2042 in Figure 2, the transmission parameters are restarted after the first AP is switched to the second AP; for example, the MSDU timer is cleared and restarted from the time AP1 sends QoS data to the STA; the number of retry times is also cleared and restarted from the time AP2 sends QoS data to the STA; the lifetime of the QoS data frame is also cleared and restarted.

[0063] The subsequent STA receives the downlink retransmission QoS data according to the transmission parameters; as shown in 2051, the transmission parameters do not reach the threshold, and the downlink retransmission QoS data is received. For example, the number of retransmissions does not exceed the preset retransmission number threshold, the MSDU timer count does not exceed the preset timer count threshold, and the lifetime of the QoS data frame does not exceed the lifetime threshold, and the QoS data frame is received and cached.

[0064] 2052. If the transmission parameter reaches the threshold, the downlink retransmission QoS data corresponding to the SN is discarded, for example, in at least one of the following situations: the number of retransmissions exceeds the preset retransmission threshold, the MSDU timer count exceeds the preset timer count threshold, and the lifetime of the QoS data frame does not exceed the lifetime threshold, then the QoS data frame is discarded.

[0065] Optionally, in the embodiments of the present disclosure, APs and STAs may be devices supporting multi-connection communication. For example, they may be represented as AP MLDs and non-AP MLDs, respectively. AP MLDs may represent access points supporting multi-connection communication capabilities, while non-AP MLDs may represent stations supporting multi-connection communication capabilities. For ease of explanation, the embodiments of the present disclosure use APs and STAs as examples; however, this does not constitute a limitation of the embodiments of the present disclosure.

[0066] Referring to Figure 3, an embodiment of the present disclosure provides a QOS data frame transmission method, which is applied to a receiving end, wherein, as shown in Figure 1, the QoS data frame includes an uplink QoS data frame, and the receiving end includes the second AP; or as shown in Figure 2, the QoS data frame includes a downlink QoS data frame, and the receiving end includes an STA.

[0067] The method comprises:

[0068] Step 301, determine the transmission parameters of the quality of service QoS data frame; wherein,

[0069] The transmission parameter accumulation station device STA is the transmission parameter before switching from the first AP to the second AP, such as the transmission parameter accumulation 1041 before the STA switches from AP1 to AP2 in Figure 1. For example, the MSDU timer is calculated from the time the STA sends the QoS data; the number of retry times needs to be accumulated from the time it is sent to AP1; the lifetime of the QoS data frame is also counted from the time the STA sends the QoS data to AP1.

[0070] Or as shown in 2041 in Figure 2, the MSDU timer is calculated from the time AP1 sends QoS data to STA; the number of retry times is also accumulated from the time AP1 sends QoS data to STA; the lifetime of the QoS data frame is also counted from the time AP1 sends QoS data to STA.

[0071] The transmission parameters are recounted after being switched from the first AP to the second AP; as shown in 1042 in Figure 1, the transmission parameters are cleared and recounted, that is, the MSDU timer is cleared and restarted from the time the STA sends the QoS data to AP2; the number of retry times is cleared and restarted from the time the STA sends the QoS data to AP2; the lifetime of the QoS data frame is also cleared and restarted from the time the STA sends the QoS data to AP2.

[0072] Or as shown in 2042 in FIG. 2 , the MSDU timer is cleared and restarted from the time AP1 sends QoS data to the STA; the number of retry times is also cleared and restarted from the time AP2 sends QoS data to the STA; and the lifetime of the QoS data frame is also cleared and restarted.

[0073] Step 302: Receive the QoS data frame according to the transmission parameters.

[0074] The subsequent end receives the uplink retransmission QoS data according to the transmission parameters; as shown in 1051 in Figure 1, the transmission parameters do not reach the threshold and the uplink retransmission QoS data is received, or as shown in 1052 in Figure 1, the transmission parameters reach the threshold and the uplink retransmission QoS data is received.

[0075] In an embodiment of the present disclosure, a receiving end determines transmission parameters for a Quality of Service (QoS) data frame; wherein the transmission parameters are accumulated from the transmission parameters of a station device (STA) before switching from a first AP to a second AP, or are recounted after switching from the first AP to the second AP; and the QoS data frame is received based on the transmission parameters. This embodiment of the present disclosure provides a transmission method for QoS data frames to support STA switching and meet the transmission requirements of UHR.

[0076] Optionally, in an embodiment of the present disclosure, the transmission parameters include the number of retransmissions of the QoS data frame, an MSDU timer count and / or a lifetime of the QoS data frame.

[0077] Among them, the retry number represents the number of retransmissions of the QoS data frame. For example, for the QoS data frame, the preset retransmission threshold is 5. When the retry number does not reach 5 times, AP2 caches the received QoS data; when the retry number reaches 5 times, AP2 can discard the cached QoS data.

[0078] The MSDU timer counts, for example, when an MSDU is delivered to the MAC layer. For example, if the MSDU timer count threshold is the value specified in the dot11 EDCA Table MSDU Lifetime parameter, then if the transmit MSDU timer reaches the dot11 EDCA Table MSDU Lifetime, the MSDU (QoS data) or undelivered MSDU segments will be discarded.

[0079] The lifetime of the QoS data frame, for example, records the duration of the existence of the QoS data frame. For example, if the lifetime of the QoS data frame is 50 milliseconds, the sending timing starts from the QoS data frame. If the lifetime of the QoS data frame is exceeded, AP2 can discard the cached QoS data.

[0080] Optionally, in an embodiment of the present disclosure, the transmission parameter accumulation station device is a transmission parameter before switching from the first AP to the second AP;

[0081] Determining the transmission parameters of the QoS data frame includes:

[0082] Receive the parameters sent by the first AP before switching from the first AP to the second AP.

[0083] In the case where the transmission parameter accumulation site device STA is the transmission parameter before it switches from the first AP to the second AP, AP1 needs to send the transmission parameters before the STA switches from the first AP to the second AP (i.e., the transmission parameters for transmitting QoS data frames with the first AP) to the receiving end. The receiving end receives the parameters sent by the first AP before switching to the second AP, and determines the transmission parameters after the switching based on the parameters.

[0084] Optionally, in the embodiment of the present disclosure, receiving the QoS data frame according to the transmission parameter includes:

[0085] If the number of retransmissions exceeds a preset retransmission threshold, the MSDU timer count exceeds a preset timer count threshold, and / or the lifetime of the QoS data frame exceeds a lifetime threshold, the QoS data frame is discarded.

[0086] Among them, when the transmission parameter reaches the threshold, the receiving end discards the retransmitted QoS data, for example, in at least one of the following situations: the number of retransmissions exceeds the preset retransmission number threshold, the MSDU timer count exceeds the preset timer count threshold, and the lifetime of the QoS data frame does not exceed the lifetime threshold, then the retransmitted QoS data corresponding to the SN is discarded.

[0087] 4 , an embodiment of the present disclosure provides a QOS data frame transmission method. Optionally, the method may be applied to a transmitting end, wherein, as shown in FIG1 , the QoS data frame includes an uplink QoS data frame, and the transmitting end includes the STA;

[0088] Or as shown in FIG2 , the QoS data frame includes a downlink QoS data frame, and the sending end includes the second AP.

[0089] The method may include the following steps:

[0090] Step 401, after the site device STA switches from the first AP to the second AP, retransmit the QoS data frame; wherein, the transmission parameters of the QoS data frame accumulate the transmission parameters before the site device STA switches from the first AP to the second AP, or the transmission parameters are recounted after switching from the first AP to the second AP.

[0091] After the STA switches from the first AP to the second AP, the transmitter retransmits the QoS data frame; and the transmission parameters accumulate the transmission parameters of the station device STA before it switches from the first AP to the second AP, such as the transmission parameter 1041 accumulated before the STA switches from AP1 to AP2 in Figure 1. For example, the MSDU timer is calculated from the time the STA sends the QoS data; the number of retry times needs to be accumulated from the time it is sent to AP1; the lifetime of the QoS data frame is also counted from the time the STA sends the QoS data to AP1.

[0092] Or as shown in 2041 in Figure 2, the MSDU timer is calculated from the time AP1 sends QoS data to STA; the number of retry times is also accumulated from the time AP1 sends QoS data to STA; the lifetime of the QoS data frame is also counted from the time AP1 sends QoS data to STA.

[0093] The transmission parameters are recounted after being switched from the first AP to the second AP; as shown in 1042 in Figure 1, the transmission parameters are cleared and recounted, that is, the MSDU timer is cleared and restarted from the time the STA sends the QoS data to AP2; the number of retry times is cleared and restarted from the time the STA sends the QoS data to AP2; the lifetime of the QoS data frame is also cleared and restarted from the time the STA sends the QoS data to AP2.

[0094] Or as shown in 2042 in FIG2 , the MSDU timer is cleared and restarted from the time AP1 sends QoS data to STA; the retry count is also cleared and restarted from the time AP2 sends QoS data to STA; the lifetime of the QoS data frame is also cleared and restarted from the time AP2 sends QoS data to STA.

[0095] Optionally, in an embodiment of the present disclosure, the transmission parameters include the number of retransmissions of the QoS data frame, an MSDU timer count and / or a lifetime of the QoS data frame.

[0096] Among them, the retry number represents the number of retransmissions of the QoS data frame. For example, for the QoS data frame, the preset retransmission threshold is 5. When the retry number does not reach 5 times, AP2 caches the received QoS data; when the retry number reaches 5 times, AP2 can discard the cached QoS data.

[0097] The MSDU timer counts, for example, when an MSDU is delivered to the MAC layer. For example, if the MSDU timer count threshold is the value specified in the dot11 EDCA Table MSDU Lifetime parameter, then if the transmit MSDU timer reaches the dot11 EDCA Table MSDU Lifetime, the MSDU (QoS data) or undelivered MSDU segments will be discarded.

[0098] The lifetime of the QoS data frame records the duration of the QoS data frame. For example, if the lifetime of the QoS data frame is 50 milliseconds, the sending time starts from the QoS data frame. If the lifetime of the QoS data frame is exceeded, AP2 can discard the cached QoS data.

[0099] In an embodiment of the present disclosure, a transmitter retransmits a QoS data frame after a STA switches from a first AP to a second AP. The transmission parameters are accumulated from the transmission parameters of the STA before the STA switches from the first AP to the second AP, or are recounted after the STA switches from the first AP to the second AP. The QoS data frame is received based on the transmission parameters. This embodiment of the present disclosure provides a QoS data frame transmission method to support STA switching and meet UHR transmission requirements.

[0100] 5 , an embodiment of the present disclosure provides a QOS data frame transmission method, which is applied to a first AP, where the first AP is the AP with which the STA communicates before switching. The method includes:

[0101] Step 501: After a station device STA switches from a first AP to a second AP, the station device STA sends transmission parameters before the STA switches to a receiving end of a QoS data frame, instructing the receiving end to determine transmission parameters of the QoS data frame based on the transmission parameters before the switching, and receive the QoS data frame.

[0102] Among them, the transmission parameters of the QoS data frame accumulate the transmission parameters before the switching, such as the transmission parameter 1041 in Figure 1 that accumulates the transmission parameter 1 before the STA switches from AP1 to AP2. For example, the MSDU timer is calculated from the time the STA sends the QoS data; the number of retry times needs to be accumulated from the time it is sent to AP1; the lifetime of the QoS data frame is also counted from the time the STA sends the QoS data to AP1.

[0103] Or as shown in 2041 in Figure 2, the MSDU timer is calculated from the time AP1 sends QoS data to STA; the number of retry times is also accumulated from the time AP1 sends QoS data to STA; the lifetime of the QoS data frame is also counted from the time AP1 sends QoS data to STA.

[0104] In the disclosed embodiment, after a STA switches from the first AP to a second AP, the first AP sends the STA's pre-switching transmission parameters to a receiving end of a QoS data frame, instructing the receiving end to determine the transmission parameters of the QoS data frame based on the pre-switching transmission parameters and receive the QoS data frame.
