Optionally, the wireless communication terminal includes, for example, at least one of a mobile phone, a wearable device, an Internet of Things (IoT) device supporting WiFi communication function, a car with WiFi communication function, a smart car, a tablet computer (Pad), a computer with wireless transceiver function, 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 smart grid, a wireless terminal device in transportation safety, a wireless terminal device in smart city, and a wireless terminal device in smart home, but is not limited thereto.

[0137] Specifically, the station device can be a terminal device or a network device with a wireless fidelity (WiFi) chip. Optionally, the station device can support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, 802.11bn, and the next generation 802.11 protocol, but is not limited thereto.

[0138] In some embodiments, the access point device can be an access point for a mobile terminal to enter a wired network. The AP is equivalent to a bridge connecting the wired network and the wireless network, and its main function is to connect various wireless network clients together and then access the Ethernet network through the wireless network. 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, 802.11a, 802.11bf, 802.11bn, and the next generation 802.11 protocol, but is not limited thereto.

[0139] Optionally, in the embodiments of the present disclosure, the AP and the STA can be devices supporting multi-link, for example, can be respectively denoted as an access point multi-link device (AP MLD) and a non-access point multi-link device (Non-AP MLD); the AP MLD can represent an access point supporting a multi-link communication function, and the non-AP MLD can represent a station supporting a multi-link communication function.

[0140] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions proposed in the embodiments of the present disclosure. It can be known by those skilled in the art that, with the evolution of system architecture and the appearance of new business scenarios, the technical solutions proposed in the embodiments of the present disclosure are also applicable to similar technical problems.

[0141] The following embodiments of the present disclosure can be applied to the communication system 100 shown in FIG. 1 or part of the subject, but are not limited thereto.

[0142] Embodiments of the present disclosure can be applied to a wireless local area network (WLAN), for example, a local area network using 802.11 series protocols. In a WLAN, a basic service set (BSS) is a basic component of a WLAN. A BSS network is composed of station devices having some association within a certain coverage area. One case of association is that the stations directly communicate with each other in an ad hoc network, which is referred to as an independent BSS (IBSS). Another more common case is that there is only one central station having a full-time management BSS in the BSS network, which is referred to as an access point device, and other STAs in the network are associated with it. Other stations in the BSS network that are not central stations are referred to as terminals, also referred to 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. In the same BSS network, due to distance, transmission power, and the like, a STA cannot detect other STAs that are far away from it, and the two are each other's hidden nodes.

[0143] FIG. 2 is an interaction diagram of an information identification method and an information receiving method according to an embodiment of the present disclosure. As shown in FIG. 2, the above method includes:

[0144] In step 201, the first device 101 determines a first wireless frame; wherein a physical header of the first wireless frame includes first identification information, and the first identification information is used to identify modulation and coding scheme (MCS) information supported by the first device 101 in a case where the first device 101 uses distributed resource units (dRUs) and / or unequal modulation (UEQM) transmission.

[0145] In a wireless local area network (WLAN), the concept of resource unit (RU) is introduced. The channel bandwidth of WLAN data transmission is divided into multiple RUs, that is, the allocation of frequency domain resources is not in units of channels, but in units of RUs. For example, in a 20MHz channel, multiple RUs can be included, such as 26-tone RU, 52-tone RU, 106-tone RU, etc. Among them, tone represents the number of subcarriers, and 26-tone RU means 26 subcarriers. Through 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, so the effective subcarriers of different RUs in a channel can be 26 (26-tone RU), 52 (52-tone RU), 106 (106-tone RU), and 242 (242-tone RU).

[0146] Currently, the same user is allowed to be allocated multiple resource units (RUs). In order to further improve the allocation flexibility and spectrum utilization of the wireless communication system, in the case that a user can be allocated multiple RUs, multiple RUs of the same user can be configured with different MCSs, that is, multiple RUs support UEQM.

[0147] Specifically, the radio transmits multiple signals at the same time, and each signal is called a spatial stream. In a multi-spatial stream transmission scenario, because the channel quality of each spatial stream can be different, the supported data modulation mode of each spatial stream can also be different. For example, for one of the spatial streams, the supported data modulation mode of the spatial stream can be 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 the multi-spatial stream UEQM mode, for example, two spatial streams SS1 and SS2, SS1 uses 16-QAM mode, and SS2 uses BPSK mode, to implement UEQM.

[0148] In some embodiments, the MCS information supported by the first device 101 is used to indicate the modulation and coding strategy adopted by the first device 101 when performing data transmission, i.e., to indicate the modulation and coding strategy adopted by the first device 101 when sending a physical layer protocol data unit (PPDU).

[0149] In the embodiments of the present disclosure, the MCS information supported by the first device 101 is associated with a plurality of communication parameters, for example, the communication parameters can include but are not limited to at least one of the following: the number of spatial streams (NSS), the modulation mode supported by each spatial stream, the coding rate, the bandwidth (BW), the type of transmission resource supported by the first device 101 (for example, resource unit RU, multiple resource unit (MRU), distributed resource unit (dRU), UEQM, etc.), whether the first device 101 supports the BW punctured channel mode, and the punctured channel density supported by the first device 101.

[0150] For example, for each communication parameter, whether the first device 101 supports each specific parameter value thereof, for example, for the number of spatial streams (NSS), the maximum NSS supported by the first device 101 can be 4, or 8 or 16. For example, for the modulation mode, the modulation mode supported by one spatial stream supported by the first device 101 can be at least one of BPSK, QPSK, 16-QAM, 64-QAM, 256-QAM, 1024-QAM, 4096-QAM. For example, for the coding rate, the coding rate supported by one spatial stream supported by the first device 101 can be 1 / 2, 2 / 3, 3 / 4, 5 / 6. For example, for the bandwidth (BW), the BW supported by the first device 101 can be at least one of 20MHz, 40MHz, 80MHz, 160MHz and 320MHz. When the first device 101 supports the BW punctured channel mode, the punctured channel density supported by the first device 101 can be at least one of 20MHz, 40MHz, 80MHz, 160MHz, 320MHz.
