[0097] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0098] As shown in FIG1 , a communication system 100 includes a station device (STA) 101 and an access point device (AP) 102 .

[0099] In some embodiments, the 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 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.

[0100] Specifically, the station device 101 may be a terminal device or network device equipped with a wireless fidelity (WiFi) chip. Optionally, the station device 101 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.

[0101] In some embodiments, the access point device 102 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:

[0107] In step 201, the site device 101 determines a first wireless frame; wherein the first wireless frame includes first identification information, and the first identification information identifies capability information of the site device supporting distributed resource unit dRU transmission; the capability information includes: whether the maximum bandwidth supported by dRU transmission is a first bandwidth value.

[0108] To further improve communication transmission range in UHR, a distributed radio unit (dRU) has been proposed. Access point devices can allocate dRUs to site devices using a variety of dRU formats, which helps increase dRU allocation flexibility. Furthermore, site devices use dRUs for uplink data transmission, which helps improve power spectral density (PSD), increase system transmission range, and improve resource utilization. Therefore, to improve the application of dRUs in UHR, it is necessary to specify the communication capabilities of site devices that support dRUs.

[0109] In the embodiment of the present disclosure, during the process of establishing an initial association with the access point device, the site device determines a first wireless frame, carries first identification information in the first wireless frame, and identifies whether the maximum bandwidth supported by the site device for dRU transmission is a first bandwidth value through the first identification information. Among them, different STAs can support different maximum bandwidths due to their own capabilities. The maximum bandwidth value supported by the site device for dRU transmission can be 20MHz, or 40MHz, 80MHz, 160MHZ or 320HZ. That is, in the embodiment of the present disclosure, the first bandwidth value can be 20MHz, or 40MHz, 80MHz, 160MHZ or 320HZ, etc., and the embodiment of the present disclosure does not limit this.

[0110] For example, some STAs can support a maximum bandwidth of 20 MHz, some can support a maximum bandwidth of 40 MHz, some can support a maximum bandwidth of 80 MHz, some can support a maximum bandwidth of 160 MHz, and some can support a maximum bandwidth of 320 MHz. A STA that can support a maximum bandwidth of 20 MHz is also referred to as a STA that only supports 20 MHz bandwidth (20 MHz only STA). Similarly, a STA that can support a maximum bandwidth of 40 MHz is also referred to as a STA that only supports 40 MHz bandwidth (40 MHz only STA). Similarly, a STA that can support a maximum bandwidth of 80 MHz is also referred to as a STA that only supports 80 MHz bandwidth (80 MHz only STA). A STA that can support a maximum bandwidth of 160 MHz is also referred to as a 160 MHz only STA. A STA that can support a maximum bandwidth of 320 MHz is also referred to as a STA that only supports 320 MHz bandwidth (320 MHz only STA).

[0111] It should be noted that, in addition to supporting the maximum bandwidth (i.e., 80MHz), 80MHz-only STAs also support bandwidths smaller than 80MHz, such as 20MHz and 40MHz. However, to conserve energy, STAs can actually operate at bandwidths smaller than the maximum supported bandwidth. For example, an 80MHz-only STA can operate at a maximum bandwidth of 20MHz during a certain period of time. Accordingly, the STA during this period is referred to as a 20MHz-only operating STA.

[0112] In some embodiments, the first wireless frame includes an ultra-high reliability capability UHR capabilities information element. The first identification information is carried in the ultra-high reliability capability UHR capabilities information element. The first identification information may occupy the first bit in the UHR capabilities information element, for example, the bit is set to a first parameter value, indicating that the site device supports dRU transmission when the maximum bandwidth is the first bandwidth value. For example, the first identification information is set to "1", indicating that the site device supports dRU transmission when the maximum bandwidth is the first bandwidth value. The first identification information is a second parameter value, indicating that the site device does not support dRU transmission when the maximum bandwidth is the first bandwidth value. For example, the first identification information is set to "0", indicating that the site device does not support dRU transmission when the maximum bandwidth is the first bandwidth value. Among them, dRU transmission includes the access point device using multiple dRU formats to allocate dRU to the site device, and the site device using dRU for uplink data transmission.

[0113] It can be understood that in the embodiments of the present disclosure, dRU transmission includes receiving and sending.

[0114] Step 202: The station device 101 sends a first radio frame.

[0115] The site device identifies, through the first identification information carried in the first radio frame, whether the maximum bandwidth supported by the site device for dRU transmission is a first bandwidth value, wherein the first bandwidth value may be 20 MHz, or 40 MHz, 80 MHz, 160 MHZ, or 320 Hz.

[0116] For example, in some embodiments, the first radio frame is sent during the connection process between the station device and the access point device. For example, during the scanning phase, the station device sends a Probe Request frame carrying the first identification information, or during the association phase, the station device sends an Association Request frame carrying the first identification information, or during the reconnection phase, the station device sends a Reassociation Request frame carrying the first identification information, or during the positioning phase, the station device sends an ML probing frame carrying the first identification information.

[0117] In step 203, the access point device 102 receives a first radio frame, wherein the first radio frame includes first identification information, which identifies capability information of the site device supporting DRU transmission; the capability information includes whether the maximum bandwidth supported by the DRU transmission is a first bandwidth value.

[0118] The access point device can determine whether the site device supports DRU transmission and the maximum bandwidth supported by the site device based on the first identification information carried in the first radio frame. Based on the capability information provided in the first identification information, the access point device can accordingly perform DRU allocation and resource scheduling to improve transmission distance and meet UHR requirements.

[0119] As another embodiment, referring to FIG. 3 , the communication method provided in the embodiment of the present disclosure further includes steps 301 to 303 .

[0120] Step 301: The site device 101 determines a first radio frame; wherein the first radio frame includes second identification information, and the second identification information identifies whether the site device supports: dRU transmission of a subcarrier at a value higher than the first bandwidth.

[0121] Different STAs can support different multi-antenna capabilities due to their own capabilities, and STAs can receive or transmit data on different subcarriers. For 20 MHz, 40 MHz, 80 MHz, and 160 MHz, the spectrum bandwidth can be divided into RUs of various sizes, including 26-subcarrier RUs (26-tone), 52-subcarrier RUs (52-tone), 106-subcarrier RUs (106-tone), 242-subcarrier RUs (the largest RU in the 20 MHz bandwidth, 242-tone), 484-subcarrier RUs (the largest RU in the 40 MHz bandwidth, 484-tone), 996-subcarrier RUs (the largest RU in the 80 MHz bandwidth), and 2*996-subcarrier RUs (the largest RU in the 160 MHz bandwidth). In addition to the 26-tone RU and 52-tone RU used for data transmission, the entire bandwidth also includes other subcarriers, such as guard subcarriers, null subcarriers, direct current (DC) subcarriers, and pilot subcarriers.

[0122] In some embodiments, the second identification information may indicate the site device's support for different numbers of subcarriers (e.g., 26-tone, 52-tone, 106-tone, 242-tone, etc.) under a large bandwidth. For example, taking the first bandwidth value as 20 MHz, the identification may be used to indicate whether the site device supports receiving and processing data transmissions from these subcarriers under different bandwidths such as 40 / 80 / 160 / 320 MHz. Transmission includes receiving and sending, for example, including the allocation of DRUs and the reception and sending of packet protocol data units (PPDUs). To implement this identification, a bit may be allocated for each mode to indicate the site device's support for the number of subcarriers under that mode. For example, binary encoding may be used, where each bit represents a mode, 0 indicates non-support, and 1 indicates support. In this way, when receiving the first radio frame, the access point device may determine the site device's support for the number of subcarriers under different bandwidths based on these bits, thereby performing appropriate resource allocation and communication scheduling.

[0123] =In some embodiments, the second identification information is carried in the UHR capabilities information element. Still taking the first bandwidth value as 20 MHz as an example, the second identification information can be a 4-bit field used to identify the site device's support for different bandwidths and subcarrier numbers. Each bit can represent the following:

[0124] Bit 1: Indicates whether the site device supports the number of dRU 26-tone subcarriers in 40 MHz bandwidth. 0 indicates no support, and 1 indicates support. Alternatively, the number of dRU 52-tone subcarriers, 106-tone subcarriers, or 242-tone subcarriers in 40 MHz bandwidth can be set.

[0125] Bit 2: Indicates whether the site device supports 52-tone subcarriers in 80 MHz bandwidth. 0 indicates no support, and 1 indicates support. Alternatively, it can be 26-tone subcarriers, 106-tone subcarriers, or 242-tone subcarriers in 80 MHz bandwidth for the DRU.

[0126] Bit 3: Indicates whether the site device supports 106-tone subcarriers in 160 MHz bandwidth. 0 indicates no support, and 1 indicates support. Alternatively, it can support 26-tone subcarriers, 52-tone subcarriers, or 242-tone subcarriers for the dRU in 160 MHz bandwidth.

[0127] Bit 4: Indicates whether the site device supports 242-tone subcarriers in 320 MHz bandwidth. 0 indicates no support, and 1 indicates support. Alternatively, it can support 26-tone subcarriers, 106-tone subcarriers, or 52-tone subcarriers for the dRU in 320 MHz bandwidth.

[0128] For example, if a site device supports 26-tone in a 40 MHz bandwidth and 52-tone in an 80 MHz bandwidth, but does not support more subcarrier numbers in 160 MHz and 320 MHz bandwidths, the first identification information is set to "1010".

[0129] In this way, when receiving the first radio frame, the access point device can determine the support status of the site device for different numbers of subcarriers under different bandwidths by parsing this field, and thus perform corresponding resource allocation and communication scheduling.

[0130] Step 302: The site device 101 sends the first radio frame.

[0131] The site device identifies whether the site device supports DRU transmission with a subcarrier having a bandwidth higher than the first bandwidth value through the second identification information carried in the first radio frame. For example, the second identification information identifies whether the site device supports DRU transmission with a subcarrier having a bandwidth higher than 20 MHz.

[0132] For example, in some embodiments, the first wireless frame is sent during the connection process between the station device and the access point device. For example, during the scanning phase, the station device sends a Probe Request frame carrying the first identification information, or during the association phase, the station device sends an Association Request frame carrying the first identification information, or during the reconnection phase, the station device sends a Reassociation Request frame carrying the first identification information, or during the positioning phase, the station device sends an ML probing frame carrying the first identification information.

[0133] Step 303: The access point device 102 receives the first radio frame, wherein the first radio frame includes second identification information, and the second identification information identifies whether the site device supports DRU transmission of a subcarrier at a bandwidth higher than a first bandwidth value.

[0134] The access point device can determine whether the site device supports DRU transmission, as well as the bandwidth and number of subcarriers supported by the site device, based on the second identification information carried in the first radio frame. Based on the capability information provided in the second identification information, the access point device can accordingly perform DRU allocation and resource scheduling to improve transmission distance and meet UHR requirements.

[0135] As another embodiment, referring to FIG. 4 , the communication method provided in the embodiment of the present disclosure further includes steps 401 to 403 .

[0136] In step 401, the site device 101 determines a first radio frame; wherein the first radio frame includes third identification information, and the third identification information identifies whether the site device supports: capability information of performing dRU transmission under each modulation mode.

[0137] Different STAs support different modulation modes due to their different capabilities. Therefore, to improve the application of dRU in UHR, it is necessary to specify the dRU transmission under the supported modulation modes of STAs.

[0138] The third identification information includes at least one of the following:

[0139] Information about the ability of a STA to transmit and receive data using a high-order modulation scheme. For example, the third identification information identifies the ability of a STA that only supports 20 MHz bandwidth to transmit and receive data using a high-order modulation scheme. In some embodiments, high-order modulation schemes include, for example, 1024 Quadrature Amplitude Modulation (1024QAM) and 4096 Quadrature Amplitude Modulation (4096QAM).

[0140] The capability information of performing dRU transmission and sending data in a high-order modulation mode. For example, the third identification information identifies the capability information of a STA that only supports 20 MHz bandwidth and performs dRU transmission and sending data in a high-order modulation mode.

[0141] The capability information of the dRU to transmit and receive data in a low-order modulation mode. For example, the third identification information identifies the capability information of the STA that only supports 20MHz bandwidth to transmit and receive data in a low-order modulation mode. In some embodiments, the low-order modulation mode includes at least one of the following: binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), 16-quadrature amplitude modulation (16-QAM), or 256-quadrature amplitude modulation (256-QAM).

[0142] The capability information of the STA to transmit and send data in a dRU transmission under a low-order modulation mode. For example, the third identification information identifies the capability information of the STA that only supports 20 MHz bandwidth to transmit and receive data in a dRU transmission under a low-order modulation mode.

[0143] The third identification information is carried in the UHR-MCS and SS set information element of the first radio frame. The UHR-MCS and SS set information element includes the data transmission capability field Rx MAX NSS MCS of the site device under the low-order modulation mode and the data transmission capability field Tx MAX NSS MCS of the site device under the high-order modulation mode, as shown in Table 1 below:

[0144] Table 1:

[0145] In some embodiments, the UHR-MCS and SS set information element further includes a modulation and coding scheme (MCS) identifier, which identifies the MCS used by the dRU PPDU transmitted by the site device in the distributed resource unit environment, where the MCS is represented as, for example, MCS13-14.

[0146] Step 402: The site device 101 sends the first radio frame.

[0147] The site device identifies, through the third identification information carried in the first radio frame, whether the site device supports: capability information of performing dRU transmission under each modulation mode.

[0148] For example, in some embodiments, the first wireless frame is sent during the connection process between the station device and the access point device. For example, during the scanning phase, the station device sends a Probe Request frame carrying the first identification information, or during the association phase, the station device sends an Association Request frame carrying the first identification information, or during the reconnection phase, the station device sends a Reassociation Request frame carrying the first identification information, or during the positioning phase, the station device sends an ML probing frame carrying the first identification information.

[0149] In step 403 , the access point device 102 receives the first radio frame; wherein the first radio frame includes third identification information, and the third identification information identifies whether the site device supports: capability information of performing dRU transmission in each modulation mode.

[0150] The access point device can determine the modulation modes supported by the station device based on the third identification information carried in the first radio frame. Based on the capability information provided in the second identification information and the third identification information, the access point device can understand the station device's transmission capabilities under different modulation modes, thereby optimizing and adjusting communication parameters as needed to improve communication performance and efficiency and increase spectrum utilization.
