As used in this specification and the appended claims, the term "if" may be interpreted contextually as "when", "upon" or "in response to" determining "or" in response to detecting ".

Furthermore, in the description of the present application and the appended claims, the terms "first," "second," "third," and the like are used for distinguishing between descriptions and not necessarily for describing or implying relative importance.

Reference throughout this specification to "one embodiment" or "some embodiments," or the like, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," or the like, in various places throughout this specification are not necessarily all referring to the same embodiment, but rather mean "one or more but not all embodiments" unless specifically stated otherwise. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless expressly specified otherwise.

Fig. 1 is a schematic diagram illustrating an application scenario of a wireless data transmission method.

Referring to fig. 1, in this scenario, the system includes a Server (Server) 11, a Root wireless access point (Root AP) 12, a relay wireless access point 1 (Repeater AP 1) 13, a relay wireless access point 2 (Repeater AP 2) 14, a relay wireless access point 3 (Repeater AP 3) 14, and a wireless Station (Wi-Fi Station, STA 1) 16. The root wireless access point 12 is connected to the server 11, and the server 11 may be a server, a host, or a core network, etc. providing services. The Root wireless access point (Root AP) 12, the relay wireless access point 1 (Repeater AP 1) 13, the relay wireless access point 2 (Repeater AP 2) 14, and the relay wireless access point 3 (Repeater AP 3) 14 may be wireless network devices, such as a wireless router, a wireless switch, a wireless signal amplifier, and the like. The embodiment of the present application does not set any limit to the specific type of the wireless network device. The wireless workstation 16 may be a user device capable of being networked through a wireless network, such as a smart phone, a notebook computer, a tablet computer, etc., or a terminal device supporting wireless networking, etc., which is not limited herein.

Figure 2 shows an architecture of multi-level Wi-Fi networking in the prior art.

In the scenario shown in fig. 1, when STA1 performs data interaction with AP0, reference may be made to the architecture shown in fig. 2. Referring to the drawing, the root wireless access point includes a wireless access module (AP 0), the relay wireless access point 1 includes a wireless access module (AP 1) and a virtual wireless station (VSTA 1), the relay wireless access point 2 includes a wireless access module (AP 2) and a virtual wireless station (VSTA 2), and the relay wireless access point 3 includes a wireless access module (AP 3) and a virtual wireless station (VSTA 3). AP0 is connected with VSTA1, AP1 is connected with VSTA2, AP2 is connected with VSTA3, and AP3 is connected with STA1.

When the AP0 performs data interaction with the STA1, the downlink direction needs to pass through:

AP0 → relay wireless access point 1 (VSTA 1 → AP 1) → relay wireless access point 2 (VSTA 2 → AP 2) → relay wireless access point 3 (VSTA 3 → AP 3) → STA1. In this process, at least four air interface interactions are required.

Correspondingly, the uplink direction needs to pass through:

STA1 → relay wireless access point 3 (AP 3 → VSTA 3) → relay wireless access point 2 (AP 2 → VSTA 2) → relay wireless access point 1 (AP 1 → VSTA 1) → AP0. In this process, at least four air interface interactions are also required.

When all the devices are in a collision domain, the probability of acquiring an air interface by each device is the same, and then 64 times of air interface interaction are required to be performed by one interaction of the Server and the STA1 on average. The deeper the cascade level of the STA is, the more the number of devices in the collision domain is, the more the number of times of air interface interaction needs to be experienced, the larger the time delay overhead of the air interface interaction is, and the more difficult the quality of the low-delay service is to be ensured.

Therefore, the application provides a wireless data transmission method, which can be applied to one of a plurality of sequentially cascaded wireless access point devices. The wireless access point equipment comprises a wireless access module, a first virtual transmission module and a second virtual transmission module. And the wireless access module of the wireless access point equipment simultaneously sends uplink data to the second virtual transmission module of the previous wireless access point equipment and sends downlink data to the first virtual transmission module of the next wireless access point.

The method comprises the steps of receiving downlink data from a superior wireless access point device through a first virtual transmission module in the wireless access point device, receiving uplink data from a subordinate wireless access point device through a second virtual transmission module, and forwarding the received uplink data and the received downlink data through a wireless access module. Because the wireless access module simultaneously sends the uplink data and the downlink data, the uplink air interface and the downlink air interface can be combined, the number of times of air interface interaction is effectively reduced, the time delay overhead of air interface interaction is further reduced, and the quality of low-delay service is ensured.

The operating system in the wireless network device may be a linnas (Linux) system, an Android (Android) system, a dammony system (Harmony OS), or the like. Here, an operating system of a wireless network device is described as an example of a hong meng system.

In some embodiments, a hongmeng system may be divided into four layers, including a kernel layer, a system services layer, a framework layer, and an application layer, with communication between the layers through a software interface.

As shown in FIG. 4, the Kernel Layer includes a Kernel Abstraction Layer (KAL) and a driver subsystem. The KAL comprises a plurality of kernels, such as a Kernel Linux Kernel of a Linux system, a Kernel LiteOS of a lightweight Internet of things system and the like. The Driver subsystem may then include a Hardware Driver Foundation (HDF). The hardware driving framework can provide a unified peripheral access capability and a driving development and management framework. The kernel layer of the multi-kernel can select the corresponding kernel to process according to the requirements of the system.

The system service layer is the core capability set of the Hongmon system, and provides services for the application program through the framework layer. The layer may include:

system basic capability subsystem set: and basic capability is provided for operations of running, scheduling, migrating and the like of the distributed application on multiple devices of the Hongmon system. The system can comprise subsystems such as a distributed soft bus, distributed data management, distributed task scheduling, ark multi-language runtime, a public base, multi-mode input, graphics, security, artificial Intelligence (AI), a user program framework and the like. The ark multi-language runtime provides a system class library based on the C or C + + or JavaScript (JS) multi-language runtime, and may also provide runtime for a Java program (i.e., a part developed by Java language in an application program or framework layer) that is statically made using the ark compiler.

Basic software service subsystem set: a common, general-purpose software service is provided for the hongmeng system. Subsystems such as event notification, telephony, multimedia, design For X (DFX), MSDP & DV, etc. may be included.

The APIs supported by hong meng system devices may also vary depending on the level of componentized clipping of the system.

The application layer comprises system applications and third-party non-system applications. The system applications may include applications installed by default on electronic devices such as desktops, control bars, settings, telephones, etc. The extended applications may be unnecessary applications that are developed and designed by the manufacturer of the electronic device, such as applications for electronic device housekeeping, change machine migration, notes, weather, and the like.

Fig. 5 shows a schematic flow chart of a wireless data transmission method provided by the present application, and fig. 6 shows a framework schematic diagram when the wireless data transmission method provided by the present application is applied. By way of example and not limitation, the method may be applied in the wireless access point device 200 described above.

Referring to fig. 5, the method includes:

s301, a first virtual transmission module of the wireless access point device receives downlink data sent by a wireless access module of the upper-level wireless access point device.

S302, a second virtual transmission module of the wireless access point device receives uplink data sent by a wireless access module of a next-stage wireless access point device.

And S303, the wireless access module of the wireless access point device simultaneously sends uplink data to the second virtual transmission module of the upper-level wireless access point device and sends downlink data to the first virtual transmission module of the lower-level wireless access point device.

In some embodiments, the first Virtual transmission module is a Virtual Fronthaul STA (VFSTA) configured to receive downlink data transmitted by a previous stage of wireless access point device. The second Virtual transmission module is a Virtual Backhaul STA (VBSTA) and is configured to receive uplink data sent by the next-stage wireless access point device. The wireless Access Point (AP) module is used for performing wireless connection with other wireless Access Point devices and STAs. When the AP module is connected to the VFSTA and the VBSTA, downlink data may be transmitted to the VFSTA and the VBSTA, and uplink data may be transmitted to the VBSTA.

In this embodiment, referring to fig. 6, a plurality of wireless access point devices are cascaded in sequence, and when the cascade level of the wireless access point devices is the lowest level, the wireless access point device is a Root AP. The Root AP is connected with the server side equipment. The VBSTA of the Root AP receives uplink data sent by an AP module (AP 1) of next-level wireless access point equipment (Repeater AP 1) and forwards the uplink data to an AP module (AP 0) of the Root AP.

When the cascade hierarchy of the wireless access point device is the highest level, the wireless access point device is Repeater AP3 and is connected to the client device (STA 1).

The AP module (AP 3) of Repeater AP3 receives the uplink data from STA1. The AP3 transmits uplink data from the STA1 to a second virtual transmission module (VBSTA 2) of the upper-level wireless access point device (Repeater AP 2).

The VFSTA of Repeater AP3 receives the downlink data transmitted from AP 2. The AP3 transmits the downlink data to the client device.

Fig. 7 shows a schematic diagram of data forwarding of various modules in a wireless access point device.

It should be noted that, when forwarding the received uplink data and downlink data to the AP, the VFSTA and the VBSTA may refer to the data flow shown in fig. 7. Wherein, the VBSTA and the VFSTA do not actively occupy the air interface to transmit data, but forward the received data to the AP through bridging (Bridge). Then, the uplink data and the downlink data are simultaneously transmitted through the AP. In transmission, uplink data and downlink data may be integrated into one signal by Orthogonal Frequency Division Multiple Access (OFDMA), and transmitted to the VFSTA of the upper stage and the VBSTA of the lower stage at the same time.

In some embodiments, the bridging may be configured with reference to the bridging forwarding table shown in table 1.

TABLE 1

Destination address	Source port	Destination port
			-	VFSTA	AP
-	VBSTA	AP

The destination address of the uplink data may be an ip address of the server, the destination address of the downlink data may be an ip address of the client, and the specific destination address is subject to configuration during application.

After the bridge is configured according to table 1, if the source port of the packet received by the bridge is VFSTA or VBSTA, the packet is directly forwarded to the AP.

In still other embodiments, referring to fig. 8, repeater AP2 and Repeater AP3 are connected to Repeater AP1, wireless station 1 (STA 1) is connected to AP2, and wireless station 2 (STA 2) is connected to AP 3. The Repeater AP1 may create a VBSTA1'. The AP2 transmits the uplink data transmitted by the STA1 to the VBSTA1, and the AP3 transmits the uplink data transmitted by the STA2 to the VBSTA1'.

In this case, the bridging may be configured with reference to the bridging forwarding table shown in table 2.

TABLE 2

Destination address	Source port	Destination port
			-	VFSTA1	AP1
-	VBSTA1	AP1
			-	VBSTA1’	AP1

After the bridging is configured according to table 2, if the source ports of the packets received by the bridging are VFSTA1, VBSTA1, and VBSTA1', the packets are directly forwarded to AP1.

In this embodiment, since the AP is used to simultaneously transmit the uplink data and the downlink data, when all the devices are in the same collision domain, the Server and the STA1 need to experience 25 air interface interactions on average for one interaction. Compared with the prior art, the number of times of air interface interaction is obviously reduced, the time delay overhead of the air interface interaction can be effectively reduced, and the quality of low-time delay service is ensured.

The wireless data transmission system comprises a Server device (Server), a first wireless access point device (Root AP), one or more second wireless access point devices (Repeater AP1 and Repeater AP 2), a third wireless access point device (Repeater AP 3) and a client device (Wi-Fi Station). The server device is connected with the first wireless access point device. The first wireless access point device, the one or more second wireless access point devices, and the third wireless access point device are cascaded in sequence. The third wireless access point device is connected with the client, and the first wireless access point device, the second wireless access point device and the third wireless access point device respectively comprise a wireless access module (AP), a first virtual transmission module (VFSTA) and a second virtual transmission module (VBSTA).

The first wireless access point equipment receives the downlink data and sends the downlink data to the second wireless access point equipment through the wireless access module. The second wireless access point device receives the downlink data through the first virtual transmission module and sends the downlink data to the third wireless access point device through the wireless access module. And the third wireless access point equipment receives the downlink data through the first virtual transmission module and sends the downlink data to the client.

For a specific implementation manner in operation, reference may be made to the example in the foregoing wireless data transmission method, and details are not described herein.

In some embodiments, referring to fig. 6, when the second wireless access point device is a plurality of devices (Repeater AP1 and Repeater AP 2), the second wireless access point device (Repeater AP 1) having the lowest cascade level is connected to the first wireless access point (Root AP) device. The second wireless access point device (Repeater AP 2) having the highest cascade hierarchy is connected to the third wireless access point device (Repeater AP 3).

When data transmission is performed between Repeater AP1 and Repeater AP2, VBSTA1 receives uplink data sent by AP2, and AP1 sends downlink data to VFSTA 2.

In some embodiments, a new wireless access point device may be added to the wireless data transmission system. When the wireless access point equipment is newly added, the newly added wireless access point equipment determines the access position of the newly added wireless access point equipment according to the configured first access information. And the first virtual transmission module of the newly added wireless access point equipment is connected with the wireless access module of the wireless access point equipment corresponding to the access position according to the configured first access information, and the second access information of the newly added wireless access point equipment is sent to the wireless access point equipment corresponding to the access position.

S402, the Repeater AP1 sends the access information of the AP1 to the AP0.

In this embodiment, access information (second access information) of AP1 may be transmitted to AP0 by VFSTA 1.
