[0098] As shown in Figure 1, the communication system 100 includes a first device 101 and a second device 102. The first device 101 and the second device 102 can be an access point (AP) or a station (STA), respectively.
[0099] 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.
[0100] In some embodiments, the site equipment includes, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports Wi-Fi 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 Wi-Fi communication, a car with Wi-Fi 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.
[0101] 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.
[0102] Optionally, in this embodiment of the disclosure, AP and STA can be devices that support multiple links. 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 link communication functions, and non-AP MLD can represent a site that supports multiple link communication functions.
[0103] 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.
[0104] 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.
[0105] 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 an Access Point (AP) device, while other sites in the BSS network that are not APs are called terminals, also known as non-AP STAs. APs 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.
[0106] Figure 2 is an interactive schematic diagram of the MCS method identification method according to an embodiment of the present disclosure. As shown in Figure 2, the method includes:
[0107] Step 201, the first device determines the first radio frame; wherein, the first radio frame includes information identifying the first device's support for one or more new MCS methods;
[0108] The supporting information includes at least one of the following:
[0109] Does the first device support each of the newly added MCS methods?
[0110] Information on the number of spatial streams supported by each of the newly added MCS methods supported by the first device in the case of transmission and / or reception;
[0111] With the rapid increase in demands for wireless network throughput and reliability from applications such as the Internet of Things (IoT), high-definition video transmission, and virtual reality (VR), the IEEE 802.11 series of standards continues to evolve to meet the challenge of higher performance. Modulation and Coding Scheme (MCS), as one of the core technologies of the Physical Layer (PHY), directly determines data transmission rate and interference resistance. In existing standards (such as 802.11n / ac / ax protocols), MCS defines data transmission rules under different channel conditions through combinations of modulation methods (such as QPSK, 16QAM, 64QAM, 256QAM) and coding rates (such as 1 / 2, 2 / 3, 3 / 4, 5 / 6). However, existing MCS methods may face a series of problems in high-density network environments, such as throughput limitations.
[0112] Therefore, in this embodiment, a new MCS method is introduced to optimize the modulation order, coding rate, and resource allocation strategy. Specifically, the new MCS method includes at least one of the following: MCS17, MCS19, MCS20, and MCS23.
[0113] Specifically, the first device can be a STA or an AP. The first device determines a first radio frame, which includes information identifying the first device's support for one or more new MCS methods;
[0114] The supporting information includes at least one of the following:
[0115] (1) Whether the first device supports each of the newly added MCS methods; for example, a flag bit is set for each newly added MCS method. If the flag bit is "1", it indicates that the first device supports the newly added MCS method; if the flag bit is "0", it indicates that the first device does not support the newly added MCS method; if the newly added MCS methods include MCS17, MCS19, MCS20 and MCS23, the flag bit occupies a total of 4 bits.
[0116] (2) The number of spatial streams supported by each of the newly added MCS methods supported by the first device in the case of transmission (Tx); wherein, the number of spatial streams supported is the number of independent data channels that the first device can use simultaneously when transmitting data; for example, for each supported newly added MCS method, the number of spatial streams supported is set to the maximum number of spatial streams available when transmitting.
[0117] (3) The number of spatial streams supported by each of the newly added MCS methods supported by the first device in the case of receiving (Rx); wherein, the number of spatial streams supported is the number of independent data channels that the first device can process simultaneously when receiving data. For example, for each supported newly added MCS method, the number of spatial streams supported is set to the maximum number of spatial streams available when receiving.
[0118] Step 202: The first device sends the first wireless frame.
[0119] Optionally, the first radio frame includes at least one of a beacon frame, a probe request frame, a probe response frame, an association request frame, a reassociation request frame, or a reassociation response frame.
[0120] Optionally, the first device can broadcast the first wireless frame via a wireless channel, enabling other devices to parse and obtain the first device's MCS support capabilities, thereby optimizing their own transmission strategies.
[0121] In this embodiment, a new MCS method, such as MCS23 (256QAM, coding rate 2 / 3), is introduced. Under high-quality channel conditions, higher-order modulation increases the bit error rate, while a moderate coding rate (e.g., coding rate 2 / 3) preserves error correction capability, balancing coding rate and reliability. In related technologies, under high interference or complex channel conditions, the bit error rate of higher-order modulation (e.g., 1024QAM) increases, limiting actual throughput. Furthermore, if channel quality deteriorates, the system dynamically switches to another new MCS method, such as switching from MCS23 to MCS19, to reduce the bit error rate.
[0122] In some embodiments, the method of adding a new MCS includes at least one of the following:
[0123] MCS17, MCS19, MCS20, and MCS23.
[0124] The method further includes at least one of the following:
[0125] The modulation and coding scheme of the MCS17 includes: Quadrature Phase Shift Keying (QPSK), with a coding rate of 2 / 3;
[0126] The modulation and coding scheme of the MCS19 includes: 16 Quadrature Amplitude Modulation (QAM), coding rate 2 / 3;
[0127] The modulation and coding scheme of the MCS20 includes: 16QAM, coding rate 5 / 6;
[0128] The modulation and coding schemes of the MCS23 include: 256QAM, coding rate 2 / 3, such as only supporting low-density parity-check code (LDPC coding), code length of 1944 / 3888, etc.
[0129] Specifically, modulation method refers to the process of converting digital signals into wireless signals. For example, QPSK uses 4 phase states to represent 2 bits of binary data (such as 00, 01, 10, 11); 16QAM uses 16 phase and amplitude combinations to represent 4 bits of binary data, which has higher transmission efficiency; 256QAM is a more complex modulation method that can transmit more data, but has extremely high requirements for signal quality.
[0130] The coding rate is the ratio of actual data to error correction code in a data packet. For example, a rate of 2 / 3 means that for every 3 bits, 2 are actual data and 1 is error correction code. Other details are omitted.
[0131] Among them, the MCS17 uses QPSK modulation, which, despite its lower modulation order (2 bits / symbol), provides higher error correction redundancy with a coding rate of 2 / 3, making it suitable for reliable transmission in high-interference environments. The MCS19 and MCS20 are configured with 16QAM modulation, suitable for balancing coding rate and reliability under medium signal quality conditions. For example, the coding rate of MCS20 (5 / 6) can further increase the effective data ratio. The MCS23 uses 256QAM modulation, achieving maximum throughput under high-quality channel conditions, while ensuring a certain level of noise immunity through a coding rate of 2 / 3. In this way, the first device can dynamically adjust the newly added MCS mode according to the actual channel environment to enhance anti-interference capabilities. In contrast, in related technologies, the coding rate and modulation order of the MCS are usually fixed, lacking dynamic adaptation capabilities and making it difficult to balance rate and reliability in interference environments.
[0132] In some embodiments, the support information also identifies at least one of the following:
[0133] When the first device uses a distributed resource unit (dRU), the spatial stream quantity information supported by the newly added MCS method;
[0134] When the bandwidth is greater than the first preset bandwidth, the first device adopts the dRU allocation rule.
[0135] Among them, dRU technology reduces co-channel interference by distributing spectrum resources into multiple subcarrier blocks (such as 26-tone RUs) and allocating them to different users or applications. The support capabilities of the newly added MCS method under different bandwidths (BW) and dRU configurations need to be clearly specified. For example, in situations where the bandwidth is greater than a first preset bandwidth, such as a high-bandwidth scenario of 80MHz, or an ultra-wideband channel scenario of 160MHz, the allocation of DRUs needs to consider the impact of spectrum fragmentation on MCS performance. For example, MCS23 performs better than distributed DRU allocation in contiguous spectrum blocks.
[0136] In some embodiments, the first device includes a 20MHz-only STA or a 20MHz operating STA; wherein, a 20MHz-only STA is, for example, a device that only supports 20MHz bandwidth and cannot use high bandwidth (such as 80MHz).
[0137] The supporting information includes at least one of the following:
[0138] The first identification information is used to identify the newly added MCS method; for example, the first identification information indicates whether the first device supports all (or one or more) of the newly added MCS methods; for example, a flag bit is set for all newly added MCS methods. If the flag bit is "1", it indicates that the first device supports the newly added MCS method; if the flag bit is "0", it indicates that the first device does not support the newly added MCS method.
[0139] The second identification information is used to identify whether the first device supports receiving Physical Protocol Data Units (PPDUs) with a bandwidth greater than 20MHz using the newly added MCS method. Even if the first device only operates at a bandwidth of 20MHz, it may need to receive PPDUs with higher bandwidths (such as 80MHz, 160MHz, or 320MHz). Therefore, it is necessary to clarify whether it supports receiving large-bandwidth PPDUs.
[0140] The third identification information is used to identify the dRU allocation rules under different bandwidths when the first device uses the newly added MCS method to receive PPDUs with a bandwidth greater than 20MHz. For example, 80MHz is divided into four 20MHz sub-bands, each of which can be independently allocated as a dRU. A 20MHz-only STA only uses one of its supported 20MHz dRU blocks, and the remaining sub-bands are allocated to other devices. Alternatively, for MCS17, a 20MHz-only device is only allowed to use MCS17 within its allocated 20MHz dRU to avoid decoding failures caused by attempting to receive data exceeding the bandwidth.
[0141] In some embodiments, the first device does not include a 20MHz-only STA.
[0142] The supporting information:
[0143] The fourth identification information is used to identify the number of spatial streams supported by the newly added MCS method when the first device uses a dRU and the bandwidth is less than or equal to the second preset bandwidth (80MHz). The number of spatial streams includes transmit spatial streams and / or receive spatial streams. In scenarios where the bandwidth is less than or equal to 80MHz (excluding STAs that only support 20MHz), spectrum resources can be flexibly allocated through distributed resource units (dRUs). For example, an 80MHz bandwidth is divided into four consecutive 20MHz sub-bands (sub-band 1 to sub-band 4). dRU allocation: each 20MHz sub-band can be used independently as a dRU block, or combined into wider dRUs (such as 40MHz, 60MHz, and 80MHz). For the newly added MCS method, the number of spatial streams supported by each sub-band with a different bandwidth can be clearly defined. Optionally, the number of transmit spatial streams and receive spatial streams can be different.
[0144] In some embodiments, the first device does not include a 20MHz-only STA.
[0145] The supporting information includes:
[0146] The fifth identifier is used to identify whether 60MHz effective bandwidth transmission is supported when the 20MHz subband is punctured under the second preset bandwidth condition. For example, the second preset bandwidth is 80MHz. When a 20MHz subband within the 80MHz bandwidth is punctured (e.g., subband 2 is removed), the remaining 60MHz effective bandwidth consists of subbands 1, 3, and 4. In this case, dRUs need to be reallocated and SS support adapted. Therefore, the spatial stream quantity information identified by the fourth identifier needs to be reconfigured. For example, for continuous dRU allocation after puncturing: divide the 60MHz into three 20MHz dRU blocks (subbands 1, 3, and 4), and configure the SS quantity for each of the three 20MHz dRU blocks.
[0147] In some embodiments, the physical layer capability (PHY capability) information field of the first radio frame includes a sixth identification information; the sixth identification information is used to identify whether each of the newly added MCS methods is valid;
[0148] The PHY Capability information field is typically used in wireless communication protocols to declare the core functions and technical capabilities supported by the device's physical layer (PHY). Its purpose is to quickly exchange basic support information during the initial negotiation phase, reducing redundant data transmission. This field uses bits to identify whether the device supports specific functions or technologies. Therefore, setting a sixth identifier in the PHY Capability information field facilitates the first device's interaction with other devices during the initial negotiation phase regarding the validity of each newly added MCS method.
[0149] In some embodiments, the support information corresponding to the newly added MCS method identified by the sixth identification information is set in the first information field of the first radio frame; wherein, the support information corresponding to the newly added MCS method identified by the sixth identification information is set in the first information field of the first radio frame. The detailed configuration of the newly added MCS method will only appear in the first information field when the sixth identification information of the newly added MCS method is valid in the PHY Capability field.
[0150] The first information field includes the MCS and NSS set fields;
[0151] and / or
[0152] The MCS and NSS set fields are set in the UHR capability information element of the first radio frame.
[0153] In the Physical Layer Capability (PHY Capability) field, the support status of newly added MCSs is indicated by bits. Detailed information is carried in the MCS and NSS set field only when these bits are valid. If a bit in the PHY Capability field for an MCS is 0, the MCS and NSS set field does not contain any information about that MCS to reduce signaling overhead.
[0154] In this embodiment, a new MCS method, such as MCS23 (256QAM, coding rate 2 / 3), is introduced. Under high-quality channel conditions, higher-order modulation increases the bit error rate, while a moderate coding rate (e.g., coding rate 2 / 3) preserves error correction capability, balancing coding rate and reliability. In related technologies, under high interference or complex channel conditions, the bit error rate of higher-order modulation (e.g., 1024QAM) increases, limiting actual throughput. Furthermore, if channel quality deteriorates, the system dynamically switches to another new MCS method, such as switching from MCS23 to MCS19, to reduce the bit error rate.
