[0115] Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.
[0116] As shown in Figure 1, the communication system 100 includes a station (STA) 101 and an access point (AP) 102.
[0117] In some embodiments, site device 101 includes, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports WiFi communication. Optionally, the wireless communication terminal may be at least one of, but is not limited to, a mobile phone, a wearable device, an IoT device that supports WiFi communication, a car with WiFi communication capabilities, 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 in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, or a wireless terminal device in a smart home.
[0118] Specifically, site device 101 can be a terminal device or network device with a Wi-Fi chip. Optionally, site device 101 can 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 to these.
[0119] In some embodiments, the access point device 102 can be an access point for mobile terminals to access a wired network. An AP acts as a bridge connecting wired and wireless networks, its main function being to connect various wireless network clients together and then connect the wireless network to an Ethernet network. Specifically, an AP can be a terminal device or network device with a wireless fidelity chip. Optionally, the AP can support various 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 to these.
[0120] Optionally, in this embodiment of the disclosure, AP and STA can be devices that support multiple connections. For example, they can be represented as Access Point Multi-Link Device (AP MLD) and Non-Access Point Multi-Link Device (Non-AP MLD), respectively. AP MLD can represent an access point that supports multiple connection communication functions, and non-AP MLD can represent a station that supports multiple connection communication functions.
[0121] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.
[0122] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.
[0123] The embodiments disclosed herein can be applied to Wireless Local Area Networks (WLANs), such as LANs using the 802.11 series of protocols. In a WLAN, a Basic Service Set (BSS) is a fundamental component. An BSS network consists of site devices with some association within a specific coverage area. One type of association is where sites communicate directly with each other in a self-organizing network; this is called an Independent Basic Service Set (IBSS). Another more common scenario is that in a BSS network, there is only one central site dedicated to managing the BSS, called the Access Point (AP) device, and all other STAs in the network are associated with it. Other sites in the BSS network that are not the central site are called terminals, also known as non-AP STAs; terminals and non-AP STAs are collectively referred to as STAs. When describing STAs, it is not necessary to distinguish between APs and non-AP STAs. Within the same BSS network, due to distance, transmission power, etc., a STA cannot detect other STAs that are far away; they are each other's hidden nodes.
[0124] Figure 2 is one of the interactive schematic diagrams of a resource identification method according to an embodiment of the present disclosure. As shown in Figure 2, the method includes:
[0125] Step 201, the AP determines the first radio frame; wherein, the first radio frame includes first identification information, the first identification information identifying the transmission resource information allocated by the site device STA;
[0126] Wherein, when the transmission resources allocated by the AP to the STA include Distributed Resource Units (dRUs), the first identification information identifies the dRU distribution type allocated to the STA.
[0127] In the UHR (Unified Response System), to further improve communication transmission distance, a distributed resource unit (dRU) is proposed. Access point devices can allocate dRUs to user equipment (STAs) using various dRU formats. These dRUs are used by STAs to receive physical layer protocol data units (PPDUs) in downlink transmissions, allowing multiple STAs to share spectrum resources within the same time period, thus improving network throughput and transmission distance. Specifically, in this embodiment, the access point device determines a first radio frame, which includes first identification information. This first identification information identifies the transmission resource information allocated by the access point (AP) to the STA; that is, the first identification information identifies the dRUs corresponding to at least a portion of the PPDUs in the first radio frame.
[0128] In wireless communication, the PPDU is the basic unit of physical layer data transmission, and downlink transmission is the process of transmitting data to user equipment in a wireless network using the PPDU. Downlink transmission can employ scheduling and multi-user technologies, such as Downlink Multi-User Multiple Input Multiple Output (DLMU-MIMO) and Downlink Orthogonal Frequency Division Multiple Access (DL OFDMA). The introduction of scheduling and multi-user technologies allows for more efficient use of wireless resources and improves network performance in downlink transmission.
[0129] In some embodiments, the first radio frame is, for example, a Multi-User Protocol Data Unit (MU PPDU). The MU PPDU includes DL OFDMA and DL MU-MIMO. First identification information may be carried in the PPDU preamble portion of the MU PPDU.
[0130] It should be understood that the dRU, discrete RU, and distributed RU mentioned in the embodiments of this disclosure refer to RUs whose subcarriers are discrete in the frequency domain. That is, RUs with this characteristic are referred to as dRUs, discrete RUs, and distributed RUs in the embodiments of this disclosure, but in practice, RUs with this characteristic may have other names, and the embodiments of this disclosure do not limit them. For ease of description, in the following embodiments, RUs with this characteristic will be referred to as dRUs.
[0131] Specifically, in WALN communication scenarios, maximum transmit power and maximum power spectral density may be limited, with the limitation on maximum power spectral density being more stringent than that on maximum transmit power; the maximum transmit power allowed is usually more constrained by power spectral density. Therefore, the transmit power of a single consecutive RU is limited by the maximum power spectral density. dRUs (differenced RUs) achieve increased transmit power without changing the power spectral density. Specifically, for dRUs and consecutive RUs containing the same number of subcarriers, the bandwidth spanned by the dRU in the frequency domain from the low-frequency start position to the high-frequency end position is greater than the frequency domain bandwidth occupied by the consecutive RU. Thus, with the same maximum power spectral density, the total transmit power of the dRU is higher than that of the consecutive RU. In other words, when power spectral density is limited, dispersing a finite number of subcarriers (such as the 26 subcarriers contained in a consecutive 26-tone RU) across a wider bandwidth, i.e., more subcarriers (such as the odd number of subcarriers in two consecutive 26-tone RUs), can increase transmit power. Therefore, compared to continuous RUs, using discrete RUs for data transmission can increase the transmit power of a single RU, thereby increasing the transmit power on a single subcarrier and thus improving the signal-to-noise ratio (SNR).
[0132] Wherein, when the transmission resources allocated by the AP to the STA include Distributed Resource Units (dRUs), the first identification information identifies the dRU distribution type allocated to the STA.
[0133] It should be noted that in the embodiments of this disclosure, the dRU distributed bandwidth can be 20MHz, 40MHz, 80MHz, 160MHz and 320MHz bandwidth, etc., and the embodiments of this disclosure do not limit it.
[0134] Step 202: Access point device 101 sends the first wireless frame.
[0135] In this process, the access point device sends a first radio frame, which identifies the dRU distribution type allocated by the access point device to the STA through the first identification information, so that the STA receives the first radio frame according to the transmission resource information indicated by the first identification information; in the presence of multiple user equipment, multiple user equipment can share spectrum resources in the same time period, thereby improving network throughput and transmission distance.
[0136] Meanwhile, when the transmission resources allocated to the STA include dRUs, the first identification information identifies the dRU distribution type allocated to the STA, so that the STA receives the first radio frame according to the dRU distribution type information indicated by the first identification information.
[0137] Step 203: The STA receives the first radio frame and receives the downlink PPDU based on the transmission resource information identified by the first identification information.
[0138] In this process, the user equipment receives a first radio frame, determines the transmission resource information for receiving downlink PPDUs based on the first identification information in the first radio frame, and receives the PPDUs to complete the data transmission process.
[0139] In some embodiments, the first identification information includes a first identification bit, which identifies the dRU distribution type allocated to the STA. For example, when the bandwidth is 80MHz, the dRU distribution type allocated to the STA may include two types. In this case, the first identification bit can occupy one bit. If the bit is set to "0", it indicates that the dRU distribution type allocated to the STA is one of the two types; if the bit is set to "1", it indicates that the dRU distribution type allocated to the STA is the other type.
[0140] In some embodiments, when the bandwidth allocated by the AP to the STA is 80MHz, the method includes:
[0141] S1: The AP determines the first radio frame; wherein the first radio frame includes first identification information, which identifies the transmission resource information allocated by the site device STA;
[0142] S2: The AP sends the first wireless frame;
[0143] Wherein, when the transmission resources allocated by the AP to the STA include dRUs and the bandwidth is 80MHz, the first identification information identifies the dRU distribution type allocated to the STA.
[0144] Optionally, in this embodiment of the disclosure, the RU distribution type at 80MHz may include the following types 1, 2, and 3:
[0145] Type 1: 80MHz;
[0146] Type 2: 20MHz (continuous 242-tone RU) + 20MHz + 40MHz (continuous 484-tone RU);
[0147] Type 3: 40MHz + 20MHz + 20MHz;
[0148] In Type 1, 80MHz is a continuous frequency band; while Type 2 and Type 3 are discontinuous frequency bands. For example, Type 2 includes a 20MHz continuous frequency band, a 20MHz continuous frequency band, and a 40MHz continuous frequency band distributed sequentially from low frequency to high frequency; while Type 3 includes a 40MHz continuous frequency band, a 20MHz continuous frequency band, and a 20MHz continuous frequency band distributed sequentially from low frequency to high frequency. In this embodiment of the present disclosure, when the bandwidth is 80MHz, the dRU distribution type allocated to the STA may include Type 2 or Type 3.
[0149] Accordingly, the first identification information includes a first identification bit, which identifies the dRU distribution type allocated to the STA. The first identification bit can occupy one bit. If the bit is set to "0", it indicates that the dRU distribution type allocated to the STA is type 2; if the bit is set to "1", it indicates that the dRU distribution type allocated to the STA is type 3.
[0150] Accordingly, when the bandwidth allocated by the AP to the STA is 80MHz, the first radio frame includes a UHR-SIG field, and the first identification information is carried in the UHR-SIG field. For example, setting the first identification bit to 1 can indicate that the dRU distribution type allocated by the AP to the STA is the aforementioned type 2; setting the first identification bit to 1 can indicate that the dRU distribution type allocated by the AP to the STA is the aforementioned type 3.

[0157] The modulation method used in the U-SIG part is binary phase shift keying (BPSK).
[0158] The U-SIG part uses binary convolutional code (BCC) encoding with a coding rate of 1 / 2.
[0159] In some embodiments, the U-SIG portion includes a physical layer version (PHY version) field, which is set to a first parameter value to identify that the first radio frame includes a UHR PPDU. For example, the PHY version field is set to "1" to identify that the first radio frame contains a UHR PPDU.

[0161] The second flag bit indicates whether the transmission resources of the first radio frame include dRU when the downlink DL / uplink UL flag bit in the U-SIG part is set to DL; for example, the second flag bit occupies one bit, and when the DL / UL flag bit in the U-SIG is set to DL, the second flag bit is set to "1", indicating that the transmission resources of the first radio frame include dRU.
[0162] Specifically, when the second identification information indicates that the bandwidth allocated to the STA is greater than or equal to 160MHz, the second identification bit is set to a reserved bit.
[0163] Step 302, access point device 101 sends the first wireless frame.
[0164] In this process, the access point device sends a first radio frame, which identifies the dRU distribution type allocated by the access point device to the STA through the first identification information. This enables the STA to receive the first radio frame according to the transmission resource information indicated by the first identification information. At the same time, the access point device determines the bandwidth information, modulation method, coding method, and coding rate according to the second identification information. In the presence of multiple user equipment, this allows multiple user equipment to share spectrum resources in the same time period, thereby improving network throughput and transmission distance.
[0165] Step 303: STA receives the first radio frame.
[0166] In this process, the user equipment receives a first radio frame, determines the transmission resource information for receiving downlink PPDUs based on the first identification information and the second identification information in the first radio frame, and receives the PPDUs to complete the data transmission process.

[0176] As an example, the PPDU preamble portion of the first radio frame is shown in Table 1 below: it includes the U-SIG field and the UHR-SIG field. The U-SIG field is used to carry bandwidth (BW) information, modulation scheme, coding scheme, etc., while the UHR-SIG field is used to carry the first identification information.
[0177] Table 1:
[0178] Wherein, when the second identification information identifies that the bandwidth allocated to the STA is 20MHz, 40MHz, 160 or 320MHz, the first identification bit is set to a reserved bit.
