[0034] 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.
[0035] The embodiments of the present disclosure provide a low-latency service transmission method, an electronic device, and a storage medium, for providing a way to transmit low-latency services.
[0036] 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.
[0037] Referring to Figure 1, Figure 1 shows one of the application scenarios of the low-latency service 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) device, 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.
[0038] In Figure 1 , the first AP (AP1) and the second AP (AP2) are attached to the same Access Point Multi-Link Device (AP MLD), and the first STA (STA1) and the second STA (STA2) are attached to the same Non-Access Point Multi-Link Device (Non-AP MLD). In the example of Figure 1 , it is assumed that AP1 and STA1 communicate via a first connection (Link 1), and similarly, AP2 and STA2 communicate via a second connection (Link 2). Furthermore, Links 1 to 2 can be multiple connections at different frequencies, for example, connections at 2.4 GHz, 5 GHz, and 6 GHz, or several connections at 2.4 GHz with the same or different bandwidths. Furthermore, multiple channels can exist within each connection. It should be understood that the communication scenario shown in Figure 1 is merely exemplary and the present disclosure is not limited thereto. For example, an AP MLD can be connected to multiple (three) non-AP MLDs, or, within each connection, the AP can communicate with multiple other types of stations.
[0039] In an embodiment of the present disclosure, as in step 101, when AP1 obtains a transmission opportunity (TXOP) under Link 1 and transmits a non-low-latency service with STA1, it is possible that AP1 has a low-latency service under Link 1 that needs to be transmitted with STA1, or AP2 has a low-latency service to transmit to STA2 under Link 2. Then, AP1 executes step 102: adding first identification information to the data frame of the first low-latency service, and using the first identification information to identify whether the first low-latency service is transmitted within the TXOP.
[0040] Specifically, if a low-latency service is transmitted after a non-low-latency service is transmitted, the latency requirement of the low-latency service may not be met; therefore, in step 102, first identification information is added to the data frame of the first low-latency service, for example, the first identification information is added to the Media Access Control layer (MAC) frame header of the data frame to identify whether the first low-latency service will be transmitted within the TXOP; for example, if the first identification information is set to "1", it means that the first low-latency service is transmitted within the TXOP; if the first identification information is set to "0", it means that the first low-latency service is not transmitted within the TXOP. The first low-latency service is a downlink service, which can be a low-latency service between AP1 and STA1, or a low-latency service between AP2 and STA2. The data frame is, for example, a protocol data unit (Physical Layer Protocol Data Unit, PPDU).
[0041] Subsequently, AP1 continues to execute step 103 and transmits the first low-latency service with STA1 in the TXOP under Link1; or transmits the first low-latency service between AP2 and STA2 in the TXOP under Link1.
[0042] Optionally, AP1 adds second identification information to the data frame of the first low-latency service to identify the connection to which the transmitted first low-latency service belongs. For example, if the low-latency service between AP1 and STA1 under Link1 is transmitted, the second identification information is identified as Link1, and if the low-latency service between AP2 and STA2 under Link2 is transmitted, the second identification information is identified as Link2. For example, the second identification information can be identified by a link bitmap. For example, if the link bitmap is set to 1, it indicates that the low-latency service corresponding to the STA under the link is transmitted.
[0043] In addition, within the TXOP, if AP1 receives a data frame of a non-low-latency service, such as a cross-link low-latency service, sent to AP2 under the first connection, the data frame of the non-low-latency service is forwarded to AP2.
[0044] Referring to Figure 2 , Figure 2 illustrates a second schematic diagram of an application scenario for providing a low-latency service transmission method according to various embodiments of the present disclosure. In Figure 2 , the first AP (AP1) and the second AP (AP2) are attached to the same AP MLD, and the first STA (STA1) and the second STA (STA2) are attached to the same non-AP MLD. In the example of Figure 2 , it is assumed that AP1 and STA1 communicate via a first connection (Link 1), and similarly, AP2 and STA2 communicate via a second connection (Link 2). Furthermore, Links 1 to 2 can be multiple connections at different frequencies, for example, connections at 2.4 GHz, 5 GHz, and 6 GHz, or several connections at 2.4 GHz with the same or different bandwidths. Furthermore, multiple channels can exist within each connection. It will be understood that the communication scenario illustrated in Figure 2 is merely exemplary and the present disclosure is not limited thereto. For example, an AP MLD can be connected to multiple (three) non-AP MLDs, or, within each connection, the AP can communicate with multiple other types of stations.
[0045] In an embodiment of the present disclosure, as in step 201, when STA1 transmits a non-low-latency service with the first AP under the first connection, it is possible that STA1 has a low-latency service to be transmitted with AP1 under Link1, or STA2 has a low-latency service to transmit to AP2 under Link2; then, after STA1 receives a PPDU of a non-low-latency service under Link1, STA1 sends a first message frame to the first AP, indicating that the first STA transmits a second low-latency service within the TXOP of the first connection; the first message frame is, for example, an acknowledgment message frame (ACK) or a block acknowledgment message frame (Block Ack, BA).
[0046] The second low-latency service is an uplink service, which may be a low-latency service between AP1 and STA1, or a low-latency service between AP2 and STA2.
[0047] Subsequently, STA1 continues to execute step 202, and transmits the second low-latency service with STA1 in the TXOP under Link1; or transmits the second low-latency service between AP2 and STA2 in the TXOP under Link1.
[0048] Optionally, STA1 adds third identification information to the data frame of the second low-latency service to identify the connection to which the transmitted second low-latency service belongs. For example, if the low-latency service between AP1 and STA1 under Link1 is transmitted, the second identification information is identified as Link1, and if the low-latency service between AP2 and STA2 under Link2 is transmitted, the second identification information is identified as Link2. For example, the third identification information can be identified by a link bitmap. For example, if the link bitmap is set to 1, it indicates that the low-latency service corresponding to the STA under that link is being transmitted.
[0049] In addition, within the TXOP, if STA1 receives a data frame of a non-low-latency service sent to STA2 under the first connection, such as a cross-Link low-latency service, the data frame of the non-low-latency service is forwarded to STA2.
[0050] 3 , an embodiment of the present disclosure provides a low-latency service transmission method. Optionally, the method may be applied to a first access point device AP. The method may include the following steps:
[0051] Step 301: When obtaining a transmission opportunity TXOP under a first connection and transmitting a non-low-latency service with a first station device STA, first identification information is added to a data frame of a first low-latency service; wherein the first identification information identifies whether the first low-latency service is transmitted within the TXOP; wherein the first low-latency service includes: a service between a first AP and a first STA under the first connection and / or a service between a second AP and a second STA under the second connection;
[0052] The first AP and the second AP belong to the same AP MLD, and the first STA and the second STA belong to the same non-AP MLD.
[0053] Referring to Figure 1, when the first AP (AP1) obtains TXOP under Link 1 and transmits non-low-latency services with STA1, it is possible that AP1 has low-latency services to transmit with STA1 under Link 1, or the second AP (AP2) has low-latency services to transmit to STA2 under Link 2. In this case, AP1 adds first identification information to the data frame of the first low-latency service, and uses the first identification information to identify whether the first low-latency service is transmitted within the TXOP.
[0054] Specifically, if a low-latency service is transmitted after a non-low-latency service, the latency requirement of the low-latency service may not be met. Therefore, first identification information is added to the data frame of the first low-latency service, for example, in the MAC frame header of the data frame, to indicate whether the first low-latency service will be transmitted within the TXOP. The first low-latency service is a downlink service, which can be a low-latency service between AP1 and STA1, or a low-latency service between AP2 and STA2. The data frame is, for example, a PPDU.
[0055] Subsequently, AP1 may transmit the first low-latency service with STA1 in the TXOP under Link1; or transmit the first low-latency service between AP2 and STA2 in the TXOP under Link1.
[0056] In an embodiment of the present disclosure, when a first AP obtains a TXOP under a first connection and transmits a non-low-latency service with a first station device STA, first identification information is added to a data frame of a first low-latency service to indicate whether the first low-latency service is transmitted within the TXOP. When a low-latency service needs to be transmitted, the low-latency service can be ensured to be transmitted within the obtained TXOP, so as to meet UHR requirements. The embodiment of the present disclosure provides a method for transmitting low-latency services.
[0057] Optionally, in the embodiment of the present disclosure, the method further includes:
[0058] The first identification information identifies that the first low-latency service is transmitted within the TXOP, and second identification information is added to the data frame of the first low-latency service; wherein the second identification information identifies the connection corresponding to the first low-latency service.
[0059] The second identification information is used to identify the connection to which the first low-latency service being transmitted belongs. For example, if the low-latency service between AP1 and STA1 under Link1 is identified by the second identification information as Link1, and if the low-latency service between AP2 and STA2 under Link2 is identified by the second identification information as Link2. For example, the second identification information can be identified by a link bitmap. For example, if the link bitmap is set to 1, it indicates that the low-latency service transmitted is the corresponding STA under that link.
[0060] Optionally, in the embodiment of the present disclosure, after the first identification information is added to the data frame of the first low-latency service, the method further includes case 1 and / or case 2:
[0061] Case 1: Within the TXOP, the low-latency service with the first STA is transmitted under the first connection; as shown in Figure 1, under Link1, the first low-latency service is transmitted with STA1 within the TXOP to ensure that the low-latency service is transmitted within the obtained TXOP.
[0062] Case 2: Within the TXOP, the low-latency service of the second AP and the second STA is transmitted under the first connection. As shown in Figure 1, under Link1, AP2 and STA2 transmit the first low-latency service within the TXOP to ensure that the low-latency service is transmitted within the obtained TXOP.
[0063] Optionally, in the embodiment of the present disclosure, the method further includes:
[0064] When obtaining a TXOP and transmitting a non-low-latency service to the first STA under the first connection, receiving a first message frame sent by the first STA, where the first message frame indicates that the first STA transmits a second low-latency service within the TXOP;
[0065] receiving, within the TXOP, a data frame of the second low-latency service;
[0066] The second low-latency service includes the service between the first STA and the first AP under the first connection and / or the service between the second STA and the second AP under the second connection.
[0067] As shown in Figure 2, when STA1 transmits non-low-latency services with the first AP under the first connection, it is possible that STA1 has low-latency services to be transmitted with AP1 under Link1, or STA2 has low-latency services to transmit to AP2 under Link2; then, after STA1 receives a PPDU of a non-low-latency service under Link1, it sends a first message frame to the first AP. After receiving the first message frame, the first AP confirms that the first STA transmits the second low-latency service within the TXOP of the first connection; the first message frame is, for example, an acknowledgment message frame (ACK) or a block acknowledgment message frame (Block Ack, BA).
[0068] The second low-latency service is an uplink service, which may be a low-latency service between AP1 and STA1, or a low-latency service between AP2 and STA2.
[0069] Subsequently, STA1 transmits the second low-latency service with STA1 in Link1 within the TXOP; or under Link1, AP2 transmits the second low-latency service with STA2 in the TXOP, and the first AP receives the second low-latency service.
[0070] Optionally, in an embodiment of the present disclosure, the data frame of the second low-latency service includes third identification information; wherein, the third identification information identifies the connection corresponding to the first low-latency service. Optionally, STA1 adds third identification information in the data frame of the second low-latency service to identify the connection to which the transmitted second low-latency service belongs. For example, the second identification information identifies the low-latency service between AP1 and STA1 under Link1 as Link1, and the second identification information identifies the low-latency service between AP2 and STA2 under Link2 as Link2. For example, the third identification information can be identified by a Link bitmap. For example, if the Link bitmap identifier is set to 1, it means that the low-latency service of the STA corresponding to the Link is transmitted.
[0071] Optionally, in an embodiment of the present disclosure, within the TXOP, data frames of non-low-latency services sent to the second AP are received under the first connection, and the data frames of the non-low-latency services are forwarded to the second AP.
[0072] If AP1 receives a data frame of a non-low-latency service, such as a cross-link low-latency service, sent to AP2 under the first connection, it forwards the data frame of the non-low-latency service to AP2.
[0073] 4 , an embodiment of the present disclosure provides a low-latency service transmission method. Optionally, the method may be applied to a station device STA. The method may include the following steps:
[0074] Step 401: When transmitting a non-low-latency service with a first access point device AP under a first connection, receiving a data frame of a first low-latency service sent by the first AP; wherein the data frame of the first low-latency service includes first identification information, and the first identification information identifies whether the first AP transmits the first low-latency service within a transmission opportunity TXOP obtained by the first AP under the first connection;
[0075] The first low-latency service includes a service between the first AP and the first STA under the first connection and / or a service between the second AP and the second STA under the second connection;
[0076] The first AP and the second AP belong to the same AP MLD, and the first STA and the second STA belong to the same non-AP MLD.
[0077] Referring to Figure 2, when the first AP (AP1) obtains a TXOP under Link 1 and transmits a non-low-latency service with STA1, it is possible that AP1 has a low-latency service to transmit with STA1 under Link 1, or the second AP (AP2) has a low-latency service to transmit to STA2 under Link 2. In this case, AP1 adds first identification information to the data frame of the first low-latency service, and uses the first identification information to identify whether the first low-latency service is transmitted within the TXOP. When STA1 transmits a non-low-latency service with the first access point device AP under the first connection, it receives the data frame of the first low-latency service sent by the first AP. For example, if the first identification information is set to "1", it indicates that the first low-latency service is transmitted within the TXOP; if the first identification information is set to "0", it indicates that the first low-latency service is not transmitted within the TXOP.
[0078] Specifically, if a low-latency service is transmitted after a non-low-latency service, the latency requirement of the low-latency service may not be met. Therefore, first identification information is added to the data frame of the first low-latency service, for example, in the MAC frame header of the data frame, to indicate whether the first low-latency service will be transmitted within the TXOP. The first low-latency service is a downlink service, which can be a low-latency service between AP1 and STA1, or a low-latency service between AP2 and STA2. The data frame is, for example, a PPDU.
[0079] Subsequently, STA1 may receive the first low-latency service transmitted with SAP1 in the TXOP under Link1; or receive the first low-latency service transmitted between AP2 and STA2 in the TXOP under Link1.
[0080] In an embodiment of the present disclosure, when a STA transmits a non-low-latency service with a first access point device (AP) under a first connection, the STA receives a data frame for a first low-latency service sent by the first AP. The data frame for the first low-latency service includes first identification information, which identifies whether the first AP transmits the first low-latency service within a transmission opportunity (TXOP) obtained under the first connection. When a low-latency service needs to be transmitted, the low-latency service can be ensured to be transmitted within the obtained TXOP, thereby meeting UHR requirements. This embodiment of the present disclosure provides a method for transmitting low-latency services.
[0081] Optionally, in an embodiment of the present disclosure,
[0082] The first identification information identifies that the first AP transmits the first low-latency service within the TXOP, and the data frame of the first low-latency service includes second identification information; wherein the second identification information identifies the connection corresponding to the first low-latency service.
[0083] The second identification information is used to identify the connection to which the first low-latency service being transmitted belongs. For example, if the low-latency service between AP1 and STA1 under Link1 is identified by the second identification information as Link1, and if the low-latency service between AP2 and STA2 under Link2 is identified by the second identification information as Link2. For example, the second identification information can be identified by a link bitmap. For example, if the link bitmap is set to 1, it indicates that the low-latency service transmitted is the corresponding STA under that link.
[0084] Optionally, in the embodiment of the present disclosure, after receiving, within the TXOP, the low-latency service transmitted by the first AP to the first STA under the first connection, the method further includes:
[0085] In the TXOP, the low-latency service transmitted by the first AP with the first STA is received under the first connection; as shown in Figure 1, under Link1, the first low-latency service is transmitted with STA1 in the TXOP to ensure that the low-latency service is transmitted within the obtained TXOP.
[0086] and / or
[0087] In the TXOP, the low-latency service of the second AP and the second STA transmitted by the first AP is received under the first connection. As shown in FIG1 , under Link1, AP2 and STA2 transmit the first low-latency service in the TXOP to ensure that the low-latency service is transmitted within the obtained TXOP.
[0088] Optionally, in the embodiment of the present disclosure, the method further includes:
[0089] When transmitting a non-low-latency service with the first AP under the first connection, sending a first message frame to the first AP, where the first message frame identifies that the first STA transmits a second low-latency service within the TXOP of the first connection;
[0090] Sending data frames of the second low-latency service within the TXOP;
[0091] The second low-latency service includes the service between the first STA and the first AP under the first connection and / or the service between the second STA and the second AP under the second connection.
[0092] As shown in Figure 2, when STA1 transmits non-low-latency services with the first AP under the first connection, it is possible that STA1 has low-latency services to be transmitted with AP1 under Link1, or STA2 has low-latency services to transmit to AP2 under Link2; then, after STA1 receives a PPDU of a non-low-latency service under Link1, it sends a first message frame to the first AP, indicating that the first STA transmits the second low-latency service within the TXOP of the first connection; the first message frame is, for example, an acknowledgment message frame (ACK) or a block acknowledgment message frame (Block Ack, BA).
[0093] The second low-latency service is an uplink service, which may be a low-latency service between AP1 and STA1, or a low-latency service between AP2 and STA2.
[0094] Subsequently, STA1 transmits the second lowest latency service with STA1 in Link1 within the TXOP; or AP2 transmits the second lowest latency service with STA2 in Link1 within the TXOP.
[0095] Optionally, in an embodiment of the present disclosure, the data frame of the second low-latency service includes third identification information; wherein, the third identification information identifies the connection corresponding to the first low-latency service. Optionally, STA1 adds third identification information in the data frame of the second low-latency service to identify the connection to which the transmitted second low-latency service belongs. For example, the second identification information identifies the low-latency service between AP1 and STA1 under Link1 as Link1, and the second identification information identifies the low-latency service between AP2 and STA2 under Link2 as Link2. For example, the third identification information can be identified by a Link bitmap. For example, if the Link bitmap identifier is set to 1, it means that the low-latency service of the STA corresponding to the Link is transmitted.
[0096] Optionally, in an embodiment of the present disclosure, within the TXOP, a data frame of a non-low-latency service sent to the second STA is received under the first connection, and the data frame of the non-low-latency service is forwarded to the second STA.
[0097] If STA1 receives a data frame of a non-low-latency service, such as a cross-link low-latency service, sent to STA2 under the first connection, the data frame of the non-low-latency service is forwarded to STA2.
[0098] Refer to Figure 5, which shows the third application scenario diagram of the low-latency service transmission method provided by each embodiment of the present disclosure. In Figure 5, the first AP (AP1) and the second AP (AP2) are attached to the same AP MLD, and the first STA (STA1) and the second STA (STA2) are attached to the same Non-AP MLD; in the example of Figure 5, AP1 and STA1 transmit non-low-latency services through the first connection (Link 1), and AP2 and STA2 have low-latency services to be transmitted under the second connection (Link 2). As shown by arrow 501, the Link2 low-latency service is transferred to Link1 for transmission, using the TXOP under Link1; specifically, STA1 sends a first message frame to AP1, indicating that STA1 transmits the low-latency service of AP2 and STA2 under Link2 within the TXOP under Link1.
[0099] When AP1 receives a data frame of a low-latency service that should be sent to AP2, it forwards the data frame to AP2.
