[0121] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0122] As shown in FIG1 , a communication system 100 includes an access point (AP) 101 and a station (STA) 102 .

[0123] In some embodiments, the access point device 101 can be an access point for a mobile terminal to enter a wired network. The AP is equivalent to a bridge connecting a wired network and a wireless network. Its main function is to connect various wireless network clients together and then connect the wireless network to the Ethernet. Specifically, the AP can be a terminal device or a network device with a wireless fidelity chip. Optionally, the AP can support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b and 802.11a, 802.11bf, 802.11bn, and support the next generation 802.11 protocol, but is not limited to this.

[0124] In some embodiments, the site device 102 includes, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports WiFi communication. Optionally, the wireless communication terminal includes, but is not limited to, at least one of a mobile phone, a wearable device, an Internet of Things device that supports WiFi communication, a car with WiFi communication, a smart car, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device used in industrial control, a wireless terminal device used in self-driving, a wireless terminal device used in remote medical surgery, a wireless terminal device used in a smart grid, a wireless terminal device used in transportation safety, a wireless terminal device used in a smart city, and a wireless terminal device used in a smart home.

[0125] Specifically, the station device 102 may be a terminal device or a network device equipped with a wireless fidelity (WiFi) chip. Optionally, the station device 102 may support multiple WLAN standards, such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, and 802.11bn, as well as the next generation 802.11 protocol, but is not limited thereto.

[0126] Optionally, in an embodiment of the present disclosure, the AP and STA may be devices supporting multiple connections, for example, they may be represented as a multi-connection access point device (AP MLD) and a multi-connection site device (Non-Access Point Multi-Link Device, Non-AP MLD), respectively; the AP MLD may represent an access point supporting multi-connection communication functions, and the non-AP MLD may represent a site supporting multi-connection communication functions.

[0127] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0128] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0129] The various embodiments of the present disclosure can be applied to wireless local area networks (WLANs), such as those using the 802.11 series of protocols. In a WLAN, a Basic Service Set (BSS) is a fundamental component of a WLAN. A BSS network consists of station devices with some association within a specific coverage area. One scenario of association is that stations communicate directly with each other in an ad hoc network, which is called an Independent Basic Service Set (IBSS). Another more common scenario is that in a BSS network, there is only one central station dedicated to managing the BSS, called an access point, and all other STAs in the network are associated with it. Other stations in the BSS network that are not the central station are called terminals, also called non-AP STAs. Terminals and non-AP STAs are collectively referred to as STAs. When describing STAs, there is no need to distinguish between APs and non-AP STAs. In the same BSS network, due to distance, transmission power, and other factors, a STA cannot detect other STAs that are farther away from it, and the two STAs are each other's hidden nodes.

[0130] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:

[0131] In step 201, the access point device 101 determines a first radio frame; wherein the first radio frame includes first identification information, and the first identification information identifies a nominal data packet padding extension value configured by the access point device for a supported target parameter; the target parameter includes a distributed resource unit dRU; the target parameter includes a distributed resource unit dRU.

[0132] The UHR defines the support capabilities of Resource Units (RUs) and Multiple Resource Units (MRUs) for Quadrature Amplitude Modulation (QAM) signaling in different formats. To further improve communication transmission distance, a distributed resource unit (DRU) is proposed. Access points can allocate DRUs to site devices using a variety of DRU formats, which increases DRU allocation flexibility. Site devices also use DRUs for uplink data transmission, which helps improve power spectral density (PSD), increase system transmission distance, and improve resource utilization.

[0133] In an embodiment of the present disclosure, during an initial association process, the access point device carries first identification information in a first radio frame, where the first identification information identifies a nominal data packet padding extension value configured by the access point device for supported target parameters.

[0134] Specifically, UHR may support DRUs up to 80MHz, so the maximum DRU is 242-tone or 484-tone, and may also include 26-tone, 52-tone, and 106-tone DRUs. Different DRUs correspond to different parameters such as spatial streams and modulation methods. Therefore, to improve the application of DRUs in UHR, it is necessary to specify the nominal data packet padding extension value for the target parameter configuration supported by the device.

[0135] It can be understood that, in the embodiment of the present disclosure, the target parameter may also include a resource unit (RU).

[0136] Optionally, the target parameter includes at least one of spatial streams (SS) and modulation mode.

[0137] In some embodiments, the first identification information includes a first identification bit and a second identification bit;

[0138] The first flag bit is used to identify whether a data packet filling extension threshold PPET exists in the first radio frame; the first flag bit is used to identify whether a data packet filling extension threshold PPET exists in the first radio frame;

[0139] The second identification bit is used to identify the nominal data packet padding extension value configured by the access point device for a supported target parameter.

[0140] Optionally, the first radio frame includes a UHR capabilities information element. The first identification information may be carried in a physical layer capability information field (PHY capabilities information field) of the UHR capabilities information element.
