[0113] As shown in Figure 1, the communication system 100 includes a first device 101 and a second device 102; wherein, the first device 101 and the second device 102 can be a station (STA), an access point (AP), an access point multi-link device (AP MLD), and a non-access point multi-link device (Non-AP MLD), respectively.

[0114] In some embodiments, the site equipment 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, and a wireless terminal device in a smart home.

[0115] Specifically, the site equipment can be a terminal device or network device with a Wi-Fi chip. Optionally, the site equipment 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.

[0116] In some embodiments, the access point device 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 the Ethernet. Specifically, an AP can be a terminal device or network device with a Wi-Fi 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.

[0117] 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.

[0118] 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.

[0119] 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.

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.

[0120] 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.

[0121] Figure 2 is an interactive schematic diagram of an information identification method and an information receiving method according to an embodiment of the present disclosure. As shown in Figure 2, the above method includes:

[0122] Step 201, the first device 101 determines the first radio frame; wherein, the first radio frame includes first identification information; the first identification information identifies the communication parameter support information of the first device when using unequal modulation UEQM transmission in a multi-spatial stream transmission scenario; the communication parameters include at least one of spatial stream number NSS, bandwidth BW, resource unit RU, multiple resource unit MRU, distributed resource unit dRU or guard interval GI.

[0123] In Wireless Local Area Networks (WLANs), the concept of a Resource Unit (RU) is introduced. The channel bandwidth for WLAN data transmission is divided into multiple RUs. This means that frequency domain resources are allocated not on a channel-by-channel basis, but on a RU-by-RU basis. For example, a 20MHz channel can contain multiple RUs, such as 26-tone RUs, 52-tone RUs, and 106-tone RUs. Here, "tone" represents the number of subcarriers; a 26-tone RU has 26 subcarriers. Using Orthogonal Frequency Division Multiple Access (OFDMA) technology, a 20MHz channel can be divided into 256 subcarriers, of which 242 are effective subcarriers. The Wi-Fi Alliance specifies that the minimum resource unit is 26 subcarriers. Therefore, the effective subcarriers of different RUs within a channel can be 26 (26-tone RU), 52 (52-tone RU), 106 (106-tone RU), and 242 (242-tone RU).

[0124] Currently, it is permissible for a single user to be allocated multiple Resource Units (RUs). To further enhance the allocation flexibility and spectrum utilization of wireless communication systems, when a user can be allocated multiple RUs, these RUs can be configured with different modulation and coding schemes (MCS), meaning that multiple RUs support unequal modulation (UEQM).

[0125] In this embodiment of the disclosure, the first device 101 carries first identification information in the first radio frame. The first identification information identifies the support information of the first device for communication parameters when using unequal modulation UEQM transmission in a multi-spatial stream (SS) transmission scenario. Specifically, the radio transmits multiple signals at the same time, and each signal is called a spatial stream.

[0126] Specifically, in multi-space stream transmission scenarios, since the channel quality of each spatial stream may be different, the data modulation supported by each spatial stream may also be different, such as binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), 16-quadrature amplitude modulation (QAM), 64-QAM, 256-QAM, 1024-QAM, and 4096-QAM. In this case, UEQM is adopted in each spatial stream. For example, for two spatial streams SS1 and SS2, SS1 adopts 16-QAM and SS2 adopts BPSK to implement UEQM.

[0127] In this embodiment of the disclosure, when using UEQM, the first identification information identifies the support status of the first device 101 for each communication parameter; the communication parameter includes at least one of the following: number of spatial streams (NSS), bandwidth (BW), resource unit (RU), multiple resource unit (MRU), distributed resource unit (dRU), or guard interval (GI).

[0128] For example, for each communication parameter, does the first device 101 support its specific parameter values? For instance, regarding the number of spatial streams (NSS), the first device 101 can support a maximum NSS of 4, 8, or 16. Taking bandwidth (BW) as an example, the first device 101 can support at least one BW of 20MHz, 40MHz, 80MHz, 160MHz, and 320MHz. RU, MRU, and dRU further include different transmission resource types; for example, the first device 101 can support at least one transmission resource type of RU, MRU, and dRU.

[0129] In some embodiments, the support information for communication parameters includes at least one of the following (1) to (9):

[0130] (1) Supported NSS information;

[0131] (2) Supported BW information;

[0132] (3) Supported modulation scheme combinations in different NSS scenarios;

[0133] (4) The coding rate information corresponding to the modulation scheme combination;

[0134] (5) The first MCS index corresponding to the first modulation and coding scheme (MCS) MCS method formed by the combination of the modulation methods;

[0135] (6) Supported combinations of transport resource types under different NSS scenarios; the transport resource types include at least one of RU, MRU or dRU;

[0136] (7) Working bandwidth information corresponding to the combination of the transmission resource types;

[0148] In this context, 64-QAM and 256-QAM indicate that SS1 uses the 64-QAM method and SS2 uses the 256-QAM method.

[0149] For example, if NSS = 3, then the second type of modulation scheme combinations include:

[0170] It should be noted that the above are just examples, and other combinations of methods are also included, which will not be described in detail here.

[0171] In item (4), the first identification information can identify the coding rate information corresponding to the modulation scheme combination. For example, taking the first type of modulation scheme combination as an example, the coding rates supported by each spatial stream can be 1kbps / 2kbps, 2kbps / 3kbps, 3kbps / 4kbps, and 5kbps / 6kbps, respectively. For example, two bits are used to identify the above coding rates respectively.

[0172] In item (5), the first identification information can identify the first MCS index corresponding to the first MCS mode formed by the modulation mode combination; for example, taking a portion of the modulation mode combinations in the third type of modulation mode combination as an example, each of the modulation mode combinations included can correspond to an index, as shown in Table 1 below:

[0173] Table 1:

[0174] Where n represents a positive integer, and the MCS index corresponding to (64-QAM, 64-QAM, 64-QAM, 256-QAM) is n. It is understood that Table 1 only shows the modulation scheme in the MCS scheme. The MCS scheme also includes other MCS parameters such as transmit power, which will not be described in detail in the embodiments of this disclosure.

[0175] In item (6), the first identification information can identify the combination of transmission resource types supported under different NSS scenarios; the transmission resource type includes at least one of RU, MRU or dRU.

[0176] As an example, when the transmission resource type includes RU, the first type of transmission resource type combination may include: a combination consisting of at least two (which may be repeated) of the following transmission resource types, with each SS corresponding to one transmission resource type:

[0177] 26-tone; 52-tone; 106-tone; 242-tone; 484-tone; 996-tone; 2×996-tone; 4×996-tone;

[0178] For example, in 4 SS scenarios, the transmission resource type combination 1 can include [26-tone; 52-tone; 106-tone; 242-tone]; the first identification information is identified by 3 bits respectively, so the corresponding first identification information can be [001, 010, 011, 100].

[0179] As an example, when the transport resource type includes MRU, the second type of transport resource type combination may include: a combination consisting of at least two (which may be repeated) of the following transport resource types, with each SS corresponding to one transport resource type:

[0180] 106-tone+26-tone; 52-tone+26-tone; 484-tone+242-tone;

[0181] 996-tone+484-tone; 996-tone+484-tone+242-tone; 2×996-tone+484-tone;

[0182] 3×996-tone and 3×996-tone+484-tone;

[0183] For example, in 4 SS scenarios, the transmission resource type combination 2 can include [106-tone+26-tone; 52-tone+26-tone; 484-tone+242-tone; 996-tone+484-tone;]; the first identification information is identified by 3 bits respectively, so the corresponding first identification information can be [001, 010, 011, 100].

[0184] As an example, when the transport resource type includes dRU, the third type of transport resource type combination can include: a combination consisting of at least two (which may be repeated) of the following transport resource types, with each SS corresponding to one transport resource type:

[0185] 26-tone; 52-tone; 106-tone; 242-tone; 484-tone;

[0186] For example, in 4 SS scenarios, the transmission resource type combination 3 can include [26-tone; 52-tone; 106-tone; 242-tone]; the first identification information is identified by 3 bits respectively, so the corresponding first identification information can be [001, 010, 011, 100].

[0187] In item (7), the first identification information can identify the working bandwidth information corresponding to each transmission resource type combination, for example, the working bandwidth corresponding to each transmission resource type combination; for example, the working bandwidth is one of 20MHz, 40MHz, 80MHz, 160MHz and 320MHz, and a working bandwidth is configured for the aforementioned transmission resource type combination 1, transmission resource type combination 2 and transmission resource type combination 3 respectively, for example, [20MHz, 40MHz, 80MHz], then the first identification information uses 3 bits to identify them respectively, and the corresponding first identification information can be [001, 010, 011].

[0188] In item (8), the first identification information can identify the second MCS index corresponding to the second MCS mode formed by the combination of transmission resource types of the first device 101; for example, taking a partial combination of transmission resource types as an example, each modulation mode combination included therein can correspond to an index, as shown in Table 2 below:

[0189] Table 2:

[0190] Where m represents a positive integer, for example, the MCS index corresponding to (64-QAM, 64-QAM, 64-QAM, 256-QAM) is m. It is understood that Table 2 only shows the modulation scheme in the MCS scheme. The MCS scheme also includes other MCS parameters such as transmit power, which will not be described in detail in the embodiments of this disclosure.

[0191] In item (9), the first identification information can identify the third MCS index corresponding to the third MCS mode; wherein, the third MCS mode is formed by combining different guard intervals GI with at least one of the following: supported working bandwidth information, the modulation mode combination, and the transmission resource type combination.

[0192] The guard intervals include, for example, 0.8 microseconds (µs), 1.6 µs, and 3.2 µs. Each GI value can form an MCS pattern with at least one of the following: supported operating bandwidth information, the modulation scheme combination, and the transmission resource type combination. An index is set for each MCS pattern, as shown in Table 3 below, taking the MCS pattern formed by GI and operating bandwidth information as an example:

[0193] Table 3:

[0194] Where P represents a positive integer, for example, the MCS index corresponding to (GI1+BW1) is P. It is understood that Table 3 only shows the GI and working bandwidth information in the MCS method. The MCS method also includes other MCS parameters such as transmit power, which will not be described in detail in this embodiment.

[0195] As an example, see Table 4, which shows an optional embodiment of the present disclosure. In each MCS mode, in addition to the modulation mode, there are also transmission resource type, BW and GI. The transmission resource type, BW and GI can be set to various parameter values, for example, GI = 800 nanoseconds (ns), 1600 ns and 3200 ns, and BW is at least one of 20 MHz, 40 MHz, 80 MHz, 160 MHz and 320 MHz, which will not be described in detail here.

[0196] As shown in Table 4, if the first identification information is set to n, it means that when the first device 101 uses unequal modulation UEQM transmission in a multi-space stream transmission scenario, the support information for communication parameters is the content corresponding to MCS index n.

[0197] Step 202: The first device 101 sends the first wireless frame;

[0198] In this process, the first device 101 sends a first radio frame to notify other devices (such as the second device 102) of the communication parameter support information when the first device uses unequal modulation UEQM transmission in a multi-space stream transmission scenario. This enables the interaction process of specific communication parameters in the UEQM mechanism. Subsequently, if other devices communicate with the first device 101, they can determine the communication parameters of the first device 101 based on the first identification information to realize the UEQM mechanism and improve the regional throughput.

[0199] Step 203: The second device 102 receives the first wireless frame.

[0200] In some embodiments, the first device includes a site device (STA) or a multi-connection site device (non-AP MLD) (an auxiliary STA of the non-AP MLD), and the first radio frame includes at least one of: a probe request frame, an association request frame, and a reassociation request frame;

[0201] or

[0202] The first device includes an access point device (AP) or a multiple access point device (AP MLD) (an auxiliary AP of an AP MLD), and the first radio frame includes at least one of a beacon frame, a probe response frame, and a reassociation response frame.

[0203] The first identification information is carried in the Ultra-High Reliability (UHR) capabilities information element of the first radio frame. For example, the UHR capabilities information element includes a Supported MCS Set field, which is set to "1" to indicate that the first identification information exists in the first radio frame. That is, it indicates the support information for communication parameters when the first device 101 uses unequal modulation UEQM transmission in a multi-space stream transmission scenario.

[0204] In some embodiments, the method further includes: a first device 101 receiving a second radio frame; wherein the second radio frame includes second identification information; the first identification information identifies the support information of communication parameters for the second device 102 when using UEQM transmission in a multi-space stream transmission scenario; the communication parameters include at least one of NSS, BW, RU, MRU or dRU.

[0205] Before data communication, the first device 101 also needs to know the communication parameter support information of the second device 102 when using UEQM transmission in the multi-space stream transmission scenario; the process of the second device 102 sending the second wireless frame to the first device 101 is similar to the process of the first device 101 sending the first wireless frame to the second device 102, and will not be described again here; and the content of the second wireless frame is similar to the content of the first wireless frame, and will not be described again here.
