Technical Field

本公开实施例涉及移动通信技术领域，具体而言，本公开实施例涉及一种低时延业务传输方法、电子设备及存储介质。The embodiments of the present disclosure relate to the field of mobile communication technology.

Background Art

点对点(Peer to Peer，P2P)的通信方式进行数据传输无需通过接入点，避免了网络拥塞引起的延迟，可进一步提高传输效率。为保证低时延业务数据的传输，WLAN中还提出了限制目标唤醒时间(Restricted Target Wake Time，R-TWT)。为了进一步减少低时延业务，数据传输过程中的传输时延，还需要对该传输过程进行优化。Peer to Peer (P2P) communication mode does not require data transmission through access points, avoiding delays caused by network congestion and further improving transmission efficiency. To ensure the transmission of low-latency service data, WLAN also proposes a restricted target wake-up time (R-TWT). In order to further reduce the transmission delay of low-latency services during data transmission, the transmission process also needs to be optimized.

Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

本公开实施例提供了一种低时延业务传输方法、电子设备及存储介质，用以提供一种低时延业务数据的传输方式。The present disclosure provides a low-latency service transmission method, an electronic device, and a storage medium. Used to provide a low-latency service data transmission method.

其中，方法和装置是基于同一申请构思的，由于方法和装置解决问题的原理相似，因此装置和方法的实施可以相互参见，重复之处不再赘述。Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

作为第一示例，参见图1，对本公开各实施例提供低时延业务传输方法的示例进行说明。如图1所示，AP(Access Point，接入点设备)、STA1(第一TDLS(Tunneled Direct Link Setup，通道直接链路建立)设备)和STA2(第二TDLS设备)在同一个基本服务集(Basic Service Sets Basic Service Set，BSS)；其中，STA1和STA2是对等的设备，该实施例中STA1的所有操作，STA2也可以对等的操作。在本公开实施例中，可以将STA1和STA2统称为STA，其中STA也可以为non-AP MLD设备。As a first example, referring to FIG. 1, an example of a low-latency service transmission method provided by each embodiment of the present disclosure is described. As shown in FIG. 1, AP (Access Point), STA1 (first TDLS (Tunneled Direct Link Setup) device) and STA2 (second TDLS device) are in the same Basic Service Sets (BSS); wherein STA1 and STA2 are peer devices, and all operations of STA1 in this embodiment can also be performed by STA2 in a peer manner. In the embodiment of the present disclosure, STA1 and STA2 may be collectively referred to as STA, wherein STA may also be a non-AP MLD device.

可选的，R-TWT的规划设备(例如AP，或称为Scheduling AP)与被规划设备(例如STA，或称为Scheduled STA)可预先建立R-TWT调度(R-TWT schedule)。AP通过广播R-TWT调度，STA与AP协商并成为某个R-TWT调度成员，AP和STA在对应的R-TWT服务阶段内只传输该R-TWT调度标识的上下行对应低时延业务，其他通信业务在该阶段内暂停或者推迟。Optionally, the R-TWT planning device (such as AP, or Scheduling AP) and the planned device (such as STA, or Scheduled STA) can pre-establish R-TWT scheduling (R-TWT schedule). AP broadcasts R-TWT scheduling, STA negotiates with AP and becomes a member of a R-TWT scheduling, AP and STA only transmit the uplink and downlink corresponding low-latency services of the R-TWT scheduling identifier during the corresponding R-TWT service phase, and other communication services are suspended or postponed during this phase.

本公开实施例中，在满足AP与R-TWT调度的成员之间映射的第二低时延业务的第二业务标识包括TDLS链路传输的第一低时延业务的第一业务标识的情况下，仅需所述STA1及所述STA2中的一方为R-TWT调度的成员(即所述STA1或所述STA2为R-TWT调度的成员)，即可实现所述AP分配传输机会TXOP的时隙给STA1或STA2，以用于STA1及STA2通过TDLS链路传输第一低时延业务。因此，本公开实施例的低时延业务传输方法，不局限于TDLS站点设备均为R-TWT调度成员，进一步提高低时延业务传输的灵活性和传输效率。In the embodiment of the present disclosure, when the second service identifier of the second low-latency service mapped between the AP and the members of the R-TWT scheduling includes the first service identifier of the first low-latency service transmitted by the TDLS link, only one of the STA1 and the STA2 needs to be a member of the R-TWT scheduling (that is, the STA1 or the STA2 is a member of the R-TWT scheduling), so that the AP can allocate the time slot of the transmission opportunity TXOP to STA1 or STA2, so that STA1 and STA2 can transmit the first low-latency service through the TDLS link. Therefore, the low-latency service transmission method of the embodiment of the present disclosure is not limited to the TDLS site devices being all members of the R-TWT scheduling, which further improves the flexibility and transmission efficiency of low-latency service transmission.

其中，如图1所示，图1所示出的交互流程包括TDLS设备间低时延业务传输的步骤，以及在低时延业务传输之前的TDLS链路业务标识到连接映射的协商步骤；具体的，图1所示的处理步骤可以包括： As shown in FIG. 1 , the interaction process shown in FIG. 1 includes a step of low-latency service transmission between TDLS devices and a negotiation step of TDLS link service identifier to connection mapping before low-latency service transmission; specifically, the processing steps shown in FIG. 1 may include:

步骤1：STA1和STA2通过TDLS发现、建立、确认等流程，成功建立TDLS链路。建立所述TDLS链路后，STA1可作为TDLS STA1(即TDLS发起端或响应端)；对应的，STA2可作为TDLS STA2(即TDLS响应端或发起端)。Step 1: STA1 and STA2 successfully establish a TDLS link through TDLS discovery, establishment, confirmation and other processes. After the TDLS link is established, STA1 can act as TDLS STA1 (i.e., TDLS initiator or responder); correspondingly, STA2 can act as TDLS STA2 (i.e., TDLS responder or initiator).

步骤2-1：AP接收STA1发送的业务标识到连接映射请求(TID-To-Link Mapping Request)帧。其中，所述TID-To-Link Mapping Request帧中携带业务标识到连接映射(TID-To-Link Mapping)元素；TID-To-Link Mapping元素可以包括TDLS链路业务标识映射(TDLS TID Mapping)标识位，所述TDLS TID Mapping标识位用于标识：TID-To-Link Mapping元素携带的参数信息是否用于TDLS设备间的TDLS链路上的业务标识映射。Step 2-1: AP receives a TID-To-Link Mapping Request frame sent by STA1. The TID-To-Link Mapping Request frame carries a TID-To-Link Mapping element; the TID-To-Link Mapping element may include a TDLS link service identifier mapping (TDLS TID Mapping) flag, and the TDLS TID Mapping flag is used to identify whether the parameter information carried by the TID-To-Link Mapping element is used for service identifier mapping on the TDLS link between TDLS devices.

作为示例，所述TID-To-Link Mapping元素的格式如以下表1所示：As an example, the format of the TID-To-Link Mapping element is shown in Table 1 below:

表1：
Table 1:

作为示例，TDLS TID Mapping标识位被设置为1时，可以标识所述TID-To-Link Mapping元素携带的参数信息用于TDLS设备间的TDLS链路上的业务标识映射；TDLS TID Mapping标识位被设置为0时，可以标识所述TID-To-Link Mapping元素携带的参数信息不用于TDLS设备间的TDLS链路上的业务标识映射。As an example, when the TDLS TID Mapping flag is set to 1, it can indicate that the parameter information carried by the TID-To-Link Mapping element is used for service identifier mapping on the TDLS link between TDLS devices; when the TDLS TID Mapping flag is set to 0, it can indicate that the parameter information carried by the TID-To-Link Mapping element is not used for service identifier mapping on the TDLS link between TDLS devices.

可选的，所述TID-To-Link Mapping元素包括Direction标识位；所述Direction标识位设置为第一参数值时，则指示所述TID-To-Link Mapping元素包括的业务标识到连接映射关系为TDLS链路对等传输。例如，所述第一参数值可以为3。Optionally, the TID-To-Link Mapping element includes a Direction flag; when the Direction flag is set to a first parameter value, it indicates that the service identifier to connection mapping relationship included in the TID-To-Link Mapping element is TDLS link peer-to-peer transmission. For example, the first parameter value may be 3.

作为示例，在所述TID-To-Link Mapping元素携带的参数信息用于TDLS设备间的TDLS链路上的业务标识映射的情况下(即TDLS TID Mapping标识位设置为1)，且所述Direction标识位设置为3时，可以标识所述TID-To-Link Mapping元素包括的业务标识到连接映射关系为TDLS链路对等传输，即该TDLS链路上映射的业务传输为TDLS设备双向对等。As an example, when the parameter information carried by the TID-To-Link Mapping element is used for service identification mapping on the TDLS link between TDLS devices (i.e., the TDLS TID Mapping flag is set to 1), and the Direction flag is set to 3, it can be marked The service identifier-to-connection mapping relationship included in the TID-To-Link Mapping element is identified as TDLS link peer-to-peer transmission, that is, the service transmission mapped on the TDLS link is bidirectional peer-to-peer of TDLS devices.

步骤2-2：AP向STA2转发TID-To-Link Mapping Request帧。可以理解的是，本公开实施例中，所述TID-To-Link Mapping Request帧是由AP转发至STA2的。Step 2-2: AP forwards the TID-To-Link Mapping Request frame to STA2. It can be understood that in the embodiment of the present disclosure, the TID-To-Link Mapping Request frame is forwarded by AP to STA2.

步骤2-3：AP接收STA2发送的业务标识到连接映射响应(TID-To-Link Mapping Response)帧；所述TID-To-Link Mapping Response帧中携带TID-To-Link Mapping元素。Step 2-3: AP receives the service identifier to connection mapping response (TID-To-Link Mapping Response) frame sent by STA2; the TID-To-Link Mapping Response frame carries the TID-To-Link Mapping element.

步骤2-4：AP向STA1转发TID-To-Link Mapping Response帧。可以理解的是，本公开实施例中，所述TID-To-Link Mapping Response帧是由AP转发至STA1的。Step 2-4: AP forwards the TID-To-Link Mapping Response frame to STA1. It can be understood that in the embodiment of the present disclosure, the TID-To-Link Mapping Response frame is forwarded by AP to STA1.

可选的，本公开实施例中，TID-To-Link Mapping Request帧中的TDLS TID Mapping标识位的参数，与TID-To-Link Mapping Response帧中的TDLS TID Mapping标识位的参数相同；和/或，TID-To-Link Mapping Request帧中的Direction标识位的参数，与TID-To-Link Mapping Response帧中的Direction标识位的参数相同；这样，可以标识STA2支持在所述TDLS链路对等传输低时延业务。Optionally, in an embodiment of the present disclosure, parameters of the TDLS TID Mapping flag in the TID-To-Link Mapping Request frame are the same as parameters of the TDLS TID Mapping flag in the TID-To-Link Mapping Response frame; and/or parameters of the Direction flag in the TID-To-Link Mapping Request frame are the same as parameters of the Direction flag in the TID-To-Link Mapping Response frame; in this way, it can be identified that STA2 supports peer-to-peer transmission of low-latency services on the TDLS link.

步骤3-1：到达STA1加入的某个R-TWT调度的目标唤醒时间时，AP向STA1发送触发帧(例如，基础触发帧Basic Trigger frame)唤醒STA1，以在R-TWT SP内与STA1进行数据交换。Step 3-1: When the target wake-up time of a certain R-TWT schedule joined by STA1 is reached, the AP sends a trigger frame (for example, a basic trigger frame Basic Trigger frame) to STA1 to wake up STA1 so as to exchange data with STA1 within the R-TWT SP.

步骤3-2：根据链路上映射的低时延通信业务标识，AP与STA1进行数据交换。其中，在数据交换的过程中，所交换的数据可以为独立的数据帧，也可以为多个连续的数据帧(即数据块)。Step 3-2: According to the low-latency communication service identifier mapped on the link, the AP exchanges data with STA1. In the process of data exchange, the exchanged data may be an independent data frame or a plurality of continuous data frames (ie, data blocks).

步骤4：AP确定TDLS链路上的业务标识中映射的业务是否包含R-TWT调度中的业务标识中的一个或者多个低时延业务，即TDLS链路传输的第一低时延业务的第一业务标识中的业务类型是否包含AP与R-TWT调度的成员之间映射的第二低时延业务的第二业务标识中的一个或者多个低时延业务。 Step 4: The AP determines whether the service mapped in the service identifier on the TDLS link includes one or more low-latency services in the service identifier in the R-TWT scheduling, that is, whether the service type in the first service identifier of the first low-latency service transmitted by the TDLS link includes one or more low-latency services in the second service identifier of the second low-latency service mapped between the AP and the members of the R-TWT scheduling.

例如，AP与R-TWT调度的成员(R-TWT调度的成员为STA1)之间映射的第二低时延业务有业务1，业务3，业务5和业务6，即在对应的R-TWT SP内，AP和STA1之间传输标识为第二低时延业务，其他业务在该SP内暂停或者推迟；相应的，第二业务标识包括上述业务分别对应的标识1，标识3，标识5和标识6。当TDLS设备间的TDLS链路映射的第一低时延业务中包含业务1，业务3，业务5和业务6中的一种或者多种业务类型(例如第一业务类中包含业务0，业务1，业务4和业务6，即第一业务标识包括上述业务分别对应的标识0、标识1、标识4和标识6)。在该示例中，第二业务标识的低时延业务(即标识1，标识3，标识5和标识6)包括第一业务标识(标识1和标识6)。For example, the second low-latency services mapped between the AP and the members of the R-TWT schedule (the members of the R-TWT schedule are STA1) include service 1, service 3, service 5 and service 6, that is, in the corresponding R-TWT SP, the transmission between the AP and STA1 is identified as the second low-latency service, and other services are suspended or postponed in the SP; accordingly, the second service identifier includes identifier 1, identifier 3, identifier 5 and identifier 6 corresponding to the above services respectively. When the first low-latency service mapped by the TDLS link between TDLS devices includes one or more service types of service 1, service 3, service 5 and service 6 (for example, the first service class includes service 0, service 1, service 4 and service 6, that is, the first service identifier includes identifier 0, identifier 1, identifier 4 and identifier 6 corresponding to the above services respectively). In this example, the low-latency services of the second service identifier (that is, identifier 1, identifier 3, identifier 5 and identifier 6) include the first service identifier (identifier 1 and identifier 6).

步骤5-1：AP确定R-TWT调度中的业务标识包含TDLS链路上的业务标识的情况下，向STA1发送MU-RTS TXS Trigger帧(多用户请求发送传输机会共享触发帧，即第一无线帧)，并在R-TWT SP内，通过传输机会共享(TXOP)方式，为STA1分配TXOP的时隙。所述TXOP的时隙用于STA1与STA2通过TDLS链路传输第一低时延业务。Step 5-1: When the AP determines that the service identifier in the R-TWT scheduling includes the service identifier on the TDLS link, it sends a MU-RTS TXS Trigger frame (multi-user request to send transmission opportunity sharing trigger frame, i.e., the first wireless frame) to STA1, and allocates a TXOP time slot to STA1 in the R-TWT SP through the transmission opportunity sharing (TXOP) method. The TXOP time slot is used for STA1 and STA2 to transmit the first low-latency service through the TDLS link.

在一个实施例中，在R-TWT调度中的业务标识不包含TDLS链路上的业务标识的情况下，不发送MU-RTS TXS Trigger帧。In one embodiment, when the service identifier in the R-TWT scheduling does not include the service identifier on the TDLS link, the MU-RTS TXS Trigger frame is not sent.

步骤5-2：STA1在接收到该MU-RTS TXS Trigger帧后，向AP发送CTS帧(Clear To send，准许发送帧)，即对AP发送的MU-RTS TXS Trigger帧进行响应。Step 5-2: After receiving the MU-RTS TXS Trigger frame, STA1 sends a CTS frame (Clear To send) to the AP, responding to the MU-RTS TXS Trigger frame sent by the AP.

步骤6：在分配的TXOP的时隙内，STA1与STA2通过TDLS链路进行点对点(Peer to Peer，简称P2P)传输，即STA1向STA2发送数据。Step 6: In the allocated TXOP time slot, STA1 and STA2 perform peer-to-peer (P2P) transmission through the TDLS link, that is, STA1 sends data to STA2.

在该数据传输的过程中，接收方(即STA2)接收到发送方(即STA1)发送的数据帧后，可以向发送方反馈确认消息(Acknowledgement，ACK)帧；接收方接收到发送方发送的多个连续的数据帧时，可以向发送方反馈块确认(Block Ack，BA)帧。During the data transmission process, after the receiver (i.e., STA2) receives the data frame sent by the sender (i.e., STA1), it can feedback an acknowledgment message (Acknowledgement, ACK) frame to the sender; when the receiver receives multiple consecutive data frames sent by the sender, it can feedback a block acknowledgment (Block Ack, BA) frame to the sender.

需要说明的是，如前文所记载的，STA1和STA2设备是对等的设备，例如，当STA1为发起方，则STA2为响应方；当STA2为发起方，则STA1 为响应方。其中，以上是实施例是以STA1向STA2发送数据为例进行说明的(STA1为发起方，STA2为响应方)，该方法也同样适用于STA2向STA1发送数据(STA2为发起方，STA1为响应方)。具体地，以主要执行步骤为例：在步骤3-2中，AP也可以与STA2进行数据交换。对应地，在步骤4中，AP在确定R-TWT调度中业务标识包含TDLS链路上的业务标识的情况下，也可向STA2发送MU-RTS TXS Trigger帧；在步骤5-2中，STA2可以向AP发送CTS帧；在步骤6中，STA2与STA1进行点对点(Peer to Peer，简称P2P)传输，即STA2向STA1发送数据。It should be noted that, as described above, STA1 and STA2 are peer devices. For example, when STA1 is the initiator, STA2 is the responder; when STA2 is the initiator, STA1 is the Is the responder. Among them, the above embodiment is explained by taking STA1 sending data to STA2 as an example (STA1 is the initiator and STA2 is the responder), and the method is also applicable to STA2 sending data to STA1 (STA2 is the initiator and STA1 is the responder). Specifically, taking the main execution steps as an example: in step 3-2, the AP can also exchange data with STA2. Correspondingly, in step 4, the AP may also send a MU-RTS TXS Trigger frame to STA2 when it determines that the service identifier in the R-TWT scheduling includes the service identifier on the TDLS link; in step 5-2, STA2 may send a CTS frame to the AP; in step 6, STA2 and STA1 perform point-to-point (Peer to Peer, referred to as P2P) transmission, that is, STA2 sends data to STA1.

本公开实施例中，AP通过第一标识信息标识AP分配TXOP的时隙给第一TDLS设备；对于可以应用于STA设备之间的R-TWT调度，第一TDLS设备与第二TDLS设备可以在没有AP参与的情况下，在TXOP的时隙内，通过二者之间建立的TDLS链路传输低时延业务数据，进一步减少了低时延业务数据传输过程中的传输时延，提高了低时延业务传输效率。In the disclosed embodiment, the AP allocates the time slot of the TXOP to the first TDLS device through the first identification information identification AP; for R-TWT scheduling that can be applied between STA devices, the first TDLS device and the second TDLS device can transmit low-latency service data within the time slot of the TXOP through the TDLS link established between the two without the participation of the AP, thereby further reducing the transmission delay in the process of low-latency service data transmission and improving the low-latency service transmission efficiency.

步骤202，发送所述第一无线帧。Step 202: Send the first wireless frame.

TWT是一种用于节能的技术，旨在进一步降低Wi-Fi网络功耗。具体的，TWT技术通过使STA和AP协商服务时间，确定STA休眠和唤醒的时间和频率；STA在该服务时间保持活跃状态并进行通信，从而可以在服务时间以外的时间进行休眠，以达到节能的目的。此外，TWT技术还可以使AP向多个STA提供更高质量的服务，使竞争或重叠最小化，在降低Wi-Fi网络功耗的同时提高频谱效率。TWT is a technology used for energy saving, which aims to further reduce the power consumption of Wi-Fi networks. Specifically, TWT technology enables STA and AP to negotiate service time to determine the time and frequency of STA sleep and wake-up; STA remains active and communicates during the service time, so that it can sleep outside the service time to achieve the purpose of energy saving. In addition, TWT technology can also enable AP to provide higher quality services to multiple STAs, minimize competition or overlap, and improve spectrum efficiency while reducing Wi-Fi network power consumption.

在低时延传输场景下，较多的应用程序的实时数据流量具有严格的延迟要求，例如，平均延迟或最大延迟的数量级在几毫秒到几十毫秒之间，以及应用程序要求实时数据流量具有极小的抖动以及较强的可靠性。为了进一步确保低时延业务的通信，在TWT的技术基础上，提出了限制目标唤醒时间。R-TWT机制允许AP使用增强的媒体访问保护机制和资源预留机制来提供更可预测的延迟，以将延迟敏感流量与其他类型的流量区分开，使得AP减少最坏情况的延迟和/或减少抖动，提供可靠性更高的服务。In low-latency transmission scenarios, real-time data traffic of more applications has strict delay requirements, for example, the average delay or maximum delay is on the order of a few milliseconds to tens of milliseconds, and the applications require real-time data traffic to have extremely small jitter and strong reliability. In order to further ensure the communication of low-latency services, based on the technology of TWT, a limit on the target wake-up time is proposed. The R-TWT mechanism allows the AP to use enhanced media access protection mechanisms and resource reservation mechanisms to provide more predictable delays to distinguish delay-sensitive traffic from other types of traffic, so that the AP can reduce the worst-case delay and/or reduce jitter, and provide more reliable services.

本公开实施例中，R-TWT的规划设备(例如AP，或称为Scheduling AP)与被规划设备(例如STA，或称为Scheduled STA)可预先建立R-TWT调度。AP通过广播R-TWT调度，STA与AP协商并成为某个R-TWT调度成员，AP和STA在对应的R-TWT服务阶段内只传输该R-TWT调度标识的上下行对应低时延业务，其他通信业务在该阶段内暂停或者推迟。具体地，R-TWT用于服务低时延业务，例如平均延迟小于10毫秒的业务。在R-TWT调度的SP内，只有标识为低时延业务的业务进行通信，其他通信业务在该阶段内暂停或者推迟，从而确保低时延业务的传输。In the disclosed embodiments, the R-TWT planning device (e.g., AP, or Scheduling AP) and the planned device (e.g., STA, or Scheduled STA) can pre-establish R-TWT scheduling. The AP broadcasts the R-TWT scheduling, and the STA negotiates with the AP and becomes a member of a certain R-TWT scheduling. The AP and the STA only transmit the uplink and downlink corresponding low-latency services identified by the R-TWT scheduling during the corresponding R-TWT service phase, and other communication services are suspended or postponed during this phase. Specifically, R-TWT is used to serve low-latency services, such as services with an average delay of less than 10 milliseconds. Within the SP scheduled by R-TWT, only services identified as low-latency services communicate, and other communication services are suspended or postponed during this phase, thereby ensuring the transmission of low-latency services.

AP确定第一无线帧；其中，所述第一无线帧中包括第一标识信息，所述第一标识信息标识所述AP分配TXOP的时隙给第一TDLS设备；所述TXOP的时隙用于所述第一TDLS设备与所述第二TDLS设备通过TDLS链路传输第一低时延业务；所述第一TDLS设备为第一R-TWT调度的成员；且所述AP与所述第一R-TWT调度的成员之间映射的第二低时延业务的第二业务标识包含有所述第一低时延业务的第一业务标识。The AP determines a first wireless frame; wherein the first wireless frame includes first identification information, and the first identification information identifies that the AP allocates a time slot of a TXOP to a first TDLS device; the time slot of the TXOP is used for the first TDLS device and the second TDLS device to transmit a first low-latency service via a TDLS link; the first TDLS device is a member of a first R-TWT scheduling; and the second low-latency service mapped between the AP and the member of the first R-TWT scheduling The second service identifier of the latency service includes the first service identifier of the first low-latency service.

进而，发送第一无线帧；例如，所述AP可以在第一R-TWT调度的SP内，发送所述第一无线帧。Then, a first radio frame is sent; for example, the AP may send the first radio frame within the SP scheduled by the first R-TWT.

可选的，本公开实施例中，所述第一无线帧可包括多用户请求发送传输机会共享触发帧MU-RTS TXS Trigger帧。Optionally, in an embodiment of the present disclosure, the first wireless frame may include a multi-user request to send transmission opportunity sharing trigger frame MU-RTS TXS Trigger frame.

其中，第一TDLS设备以及第二TDLS设备可以例如两台STA，TDLS技术使得同一个基本服务集中的两台STA在建立TDLS连接(TDLS Link，即TDLS链路/TDLS信道)后，可直接跳过AP传输数据，从而不受AP的约束，采用两台STA支持的最快速率标准进行直接传输。直接传输可以在原来链路进行，也可以切换到新的扩展信道上进行，因此能够避免由于网络拥塞而引起的数据传输延迟，对于低时延业务的传输具有重要意义。The first TDLS device and the second TDLS device may be two STAs, for example. TDLS technology enables two STAs in the same basic service set to directly skip the AP to transmit data after establishing a TDLS connection (TDLS Link, i.e., TDLS link/TDLS channel), so that they are not constrained by the AP and use the fastest rate standard supported by the two STAs for direct transmission. Direct transmission can be performed on the original link or on a new extended channel, thus avoiding data transmission delays caused by network congestion, which is of great significance for the transmission of low-latency services.

本公开实施例中，所述第一TDLS设备为第一R-TWT调度的成员。也就是说，在满足所述第二业务标识包含有所述第一业务标识的情况下，仅需所述第一TDLS设备及所述第二TDLS设备中的一方为第一R-TWT调度的成员，所述AP即可分配TXOP的时隙给第一TDLS设备，以用于所述第一TDLS设备与所述第二TDLS设备通过TDLS链路传输第一低时延业务。因此，本公开实施例不仅局限于TDLS站点设备均为R-TWT调度成员，进一步提高低时延业务传输的灵活性和传输效率。In the disclosed embodiment, the first TDLS device is a member of the first R-TWT scheduling. That is to say, when the second service identifier contains the first service identifier, only one of the first TDLS device and the second TDLS device needs to be a member of the first R-TWT scheduling, and the AP can allocate the TXOP time slot to the first TDLS device for the first TDLS device and the second TDLS device to transmit the first low-latency service via the TDLS link. Therefore, the disclosed embodiment is not only limited to the TDLS site devices being members of the R-TWT scheduling, but also further improves the flexibility and transmission efficiency of low-latency service transmission.

例如，AP与R-TWT调度的成员(R-TWT调度的成员为STA1)之间映射的第二低时延业务有业务1，业务3，业务5和业务6，即在对应的R-TWT SP内，AP和STA1之间传输标识为第二低时延业务，其他业务在该SP内暂停或者推迟；相应的，第二业务标识包括上述业务分别对应的标识1，标识3，标识5和标识6。当TDLS设备间的TDLS链路映射的第一低时延业务中包含业务1，业务3，业务5和业务6中的一种或者多种业务类型(例如第一业务类中包含业务0，业务1，业务4和业务6，即第一业务标识包括上述业务分别对应的标识0、标识1、标识4和标识6)。在该示例中，第二业务标识的低时延业务(即标识1，标识3，标识5和标识6)包括第一业务标识(标识1和标识6)。 For example, the second low-latency services mapped between the AP and the members of the R-TWT schedule (the members of the R-TWT schedule are STA1) include service 1, service 3, service 5 and service 6, that is, in the corresponding R-TWT SP, the transmission between the AP and STA1 is identified as the second low-latency service, and other services are suspended or postponed in the SP; accordingly, the second service identifier includes identifier 1, identifier 3, identifier 5 and identifier 6 corresponding to the above services respectively. When the first low-latency service mapped by the TDLS link between TDLS devices includes one or more service types of service 1, service 3, service 5 and service 6 (for example, the first service class includes service 0, service 1, service 4 and service 6, that is, the first service identifier includes identifier 0, identifier 1, identifier 4 and identifier 6 corresponding to the above services respectively). In this example, the low-latency services of the second service identifier (that is, identifier 1, identifier 3, identifier 5 and identifier 6) include the first service identifier (identifier 1 and identifier 6).

TDLS technology enables two STAs in the same basic service set to directly skip the AP to transmit data after establishing a TDLS connection (TDLS Link, i.e., TDLS link/TDLS channel), so that they are not restricted by the AP and use the fastest rate standard supported by the two STAs for direct transmission.
