Furthermore, each element, each row, or each column in the table of this disclosure can be implemented as an independent embodiment, and any combination of any element, any row, or any column can also be implemented as an independent embodiment. Currently, common modulation methods include Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), and Quadrature Amplitude Modulation (QAM). QAM is further divided into 16QAM, 256QAM, and 1024QAM. 16QAM means that one symbol can transmit 4 bits, and 4 bits can represent 16 different states or values, hence the name 16QAM. Correspondingly, 64QAM means that one symbol can transmit 6 bits, and 6 bits can represent 64 different states or values, hence the name 64QAM. 256QAM means that one symbol can transmit 8 bits, and 8 bits can represent 256 different states or values, hence the name 256QAM. 1024QAM means that one symbol can transmit 10 bits, and 10 bits can represent 1024 different states or values, hence the name 1024QAM. In the 5th generation mobile communication system (5G) new radio (NR), the PDSCH modulation scheme supports up to 1024QAM, and the PUSCH modulation scheme supports up to 256QAM. In some embodiments, the modulation and coding scheme (MCS) table for PDSCH transmission applications includes Tables 1 to 4 below. Table 1 is the MCS table for 64QAM (MCS_64QAM). Table 2 is the MCS table for 256QAM (MCS_256QAM). Table 3 is the MCS table for Ultra-Reliable Low-Latency Communications (URLLC) (MCS_URLLC). Table 4 is the MCS table for 1024QAM (MCS_1024QAM). Table 1 Table 2 Table 3 Table 4 This disclosure uses Table 1 as an example to illustrate what each column represents; the same applies to other tables. As shown in Table 1, the first column is the Modulation-Coding Scheme Index (MCS Index), which can be abbreviated as I. MCS The index ranges from 0 to 31, meaning there are 32 modulation / decoding schemes. The second column is the modulation order, which can be abbreviated as Q. m The third column represents the target code rate multiplied by 1024. The target code rate can be abbreviated as R, and x is the multiplication sign. The third column indicates the product of the target code rate and 1024; that is, the ratio of the value in the third column to 1024. For example, R x

[1024] If the value is 120, then R is the ratio of 120 to 1024 (120 / 1024). The fourth column is spectral efficiency, which refers to the number of bits that can be transmitted per unit bandwidth per second. A modulation / decoding scheme corresponds to a modulation order, a target code rate, and a spectral efficiency. A higher modulation order generally means a larger number of bits per symbol, i.e., more information can be transmitted. A higher target code rate results in more effective bits and less redundant information, allowing for the transmission of more information, but also lower interference resistance. A lower target code rate results in fewer effective bits and more redundant information. This redundant information can be used for error correction, improving interference resistance and ensuring data transmission reliability. Spectral efficiency may be affected by the preceding factors. In some embodiments, the MCS tables for PUSCH transmission applications, for Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM) waveforms, may include three tables: MCS_64QAM, MCS_256QAM, and MCS_URLLC, as shown in Tables 1 to 3 above. For Discrete Fourier Transform-Spread-Orthogonal Frequency Division Multiplexing (DFT-s-OFDM) waveforms, they may include MCS_256QAM (Table 2 above), as well as the redefined MCS_64QAM and MCS_256QAM, as shown in Tables 5 and 6 below. Table 5 In Table 5, q represents a non-fixed value. For example, when q is 1, it corresponds to the modulation scheme π / 2-BPSK, where π is the mathematical constant pi, with a value conventionally agreed to be 3.14. π / 2 is half of π. π / 2-BPSK is a phase modulation scheme, an extension of BPSK modulation. In π / 2-BPSK, the phase change of the signal is achieved by introducing a phase shift of π / 2 between each symbol. When q is 2, it corresponds to the modulation scheme QPSK. The meanings of the other columns are as shown in Table 1, and will not be repeated in this disclosure. Table 6 In Table 6, the value of q is 1 or 2. For details, please refer to the description of Table 5 above, and this disclosure will not repeat them here. In some embodiments, for downlink modulation, the correspondence between modulation scheme and modulation order can be referred to in Table 7 below. Table 7 In Table 7, the modulation order corresponding to QPSK is 2. For example, if the downlink transmission uses the modulation and coding scheme determined as shown in Table 4 above,... Assuming the network device is the I indicated by the terminal MCS =0, I MCS The corresponding modulation order is 2. Referring to Table 7, the modulation method can be determined to be QPSK. Accordingly, the modulation order corresponding to 16QAM is 4. The modulation order corresponding to 64QAM is 6. The modulation order corresponding to 256QAM is 8. In some embodiments, the correspondence between modulation scheme and modulation order for uplink modulation can be referred to in Table 8 below. Table 8 Table 8 includes the correspondence between modulation scheme and modulation order for CP-OFDM waveforms, as well as the correspondence between modulation scheme and modulation order for DFT-s-OFDM waveforms. With the development of 6G mobile communication systems, peak data rates of 100-1000 gigabits per second (Gbit / s) are required to support higher-speed services. Therefore, among various technologies for enhancing transmission rates, this disclosure utilizes a higher-order modulation scheme. For downlink transmission, using a higher-order modulation scheme... This disclosure provides a communication method in which a terminal receives first information indicating a first modulation and coding scheme. The first modulation and coding scheme belongs to a set of first modulation and coding schemes, which includes at least one modulation and coding scheme with a modulation order of 12. A modulation and coding scheme with a modulation order of 12 is a higher-order modulation and coding scheme. By using a higher-order modulation scheme, the transmission rate can be further increased, which can accommodate different service requirements, such as Extended Reality (XR) services.

The processes and information interactions between these internal interfaces can be implemented by software or programs. In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

Figure 2 is a schematic diagram of a communication method interaction according to an embodiment of the present disclosure. As shown in Figure 2, this embodiment of the present disclosure relates to a communication method for a communication system 100, the method including: In step S2101, network device 102 sends first information to terminal 101. In some embodiments, terminal 101 receives first information sent by network device 102. In some embodiments, the first information is used to indicate a first modulation and coding scheme, the first modulation and coding scheme belonging to a set of first modulation and coding schemes, the set of first modulation and coding schemes including multiple modulation and coding schemes, and the multiple modulation and coding schemes including at least one modulation and coding scheme with a modulation order of 12. In some embodiments, the first information may be an index of a first modulation and coding scheme, and the first modulation and coding scheme set may be an MCS table. The network device can indicate the first modulation and coding scheme corresponding to an index in the table. In some embodiments, a modulation order of 12 can correspond to a 4096QAM modulation scheme, but is not limited thereto. In some embodiments, each modulation and coding scheme in the first set of modulation and coding schemes corresponds to an index and a spectral efficiency, and the spectral efficiencies corresponding to any two adjacent indices have the same difference. For example, when designing the first set of modulation and coding schemes, the entire table can be designed based on the intervals of uniform spectral efficiency. The first set of modulation and coding schemes can be an MSC table, where one column is the index and the other column is the spectral efficiency. The indices can be arranged in ascending order, so the spectral efficiency also increases uniformly. In this case, the distribution of modulation and coding schemes in the first set of modulation and coding schemes is more reasonable, more compatible when selecting modulation and coding schemes, and can cover multiple spectral efficiency ranges. In some embodiments, the first set of modulation and coding schemes includes at least one modulation and coding scheme from the second set of modulation and coding schemes. The second set of modulation and coding schemes is a set of modulation and coding schemes specified in the protocol, and does not include modulation and coding schemes with a modulation order of 12. For example, at least one modulation and coding scheme from the second set can be retained, and other modulation and coding schemes can be redesigned to obtain the first set of modulation and coding schemes. The second set of modulation and coding schemes is an existing set of modulation and coding schemes in the protocol, and does not include modulation and coding schemes with a modulation order of 12. For example, the second set of modulation and coding schemes can be any one of Tables 1 to 3 above. In this embodiment, the first set of modulation and coding schemes retains at least one modulation and coding scheme from the second set of modulation and coding schemes, making the first set of modulation and coding schemes more reliable by referring to the modulation and coding schemes of existing sets of modulation and coding schemes. In some embodiments, each modulation and coding scheme in the first set of modulation and coding schemes corresponds to a code rate, the code rate ranging from N-0.5 to N+0.5, and the accuracy of the code rate being at the level of 0.001 or 0.0001. N is determined based on the modulation order and spectral efficiency corresponding to the modulation and coding scheme. For example, N can be calculated based on the modulation order and spectral efficiency, and the code rate can be determined based on N, with the code rate ranging from N-0.5 to N+0.5 and accurate to 0.001 or 0.0001. In some embodiments, the first set of modulation and coding schemes includes a modulation and coding scheme with a modulation order of 12. The code rate corresponding to a modulation order of 12 is the maximum code rate in the second set of modulation and coding schemes. The spectral efficiency of a modulation and coding scheme with a modulation order of 12 is determined based on 12 and the maximum code rate. The second set of modulation and coding schemes is the set of modulation and coding schemes specified in the protocol, and it does not include modulation and coding schemes with a modulation order of 12. For example, when designing the first set of modulation and coding schemes, if a modulation and coding scheme with a modulation order of 12 needs to be designed, a maximum code rate can be determined from the second set of modulation and coding schemes, and the spectral efficiency can be calculated based on the maximum code rate and the modulation order of 12. For example, the second set of modulation and coding schemes can be Table 1, Table 2, or Table 4, and the maximum code rate can be 948. Taking Table 4 as an example, when the modulation order is 8 and the code rate is the ratio of 948 to 1024, the spectral efficiency is 7.4063. When the modulation order is 10 and the code rate is the ratio of 948 to 1024, the spectral efficiency is 9.2578. In this embodiment, within a set of modulation and coding schemes with a modulation order of 12, a ratio of 948 to 1024 is used. Based on the modulation order of 12 and the code rate of 948, the spectral efficiency is calculated to be 11.1093 or 11.1094. The modulation and coding scheme with a modulation order of 12, a code rate ratio of 948 to 1024, and a spectral efficiency of 11.1093 or 11.1094 is one of the modulation and coding schemes in the first set of modulation and coding schemes. The code rate can also be referred to as the target code rate in other parts of this disclosure and is not limited thereto. In some embodiments, the first set of modulation and coding schemes includes a first number of modulation and coding schemes and a second number of modulation and coding schemes. The code rate and spectral efficiency corresponding to the first number of modulation and coding schemes are actual values, while the code rate and spectral efficiency corresponding to the second number of modulation and coding schemes are null values. The second number is determined based on the number of modulation order types, and the sum of the first and second numbers is 32. The fact that the code rate and spectral efficiency corresponding to the first number of modulation and coding schemes are actual values ​​can be understood as meaning that the first number of modulation and coding schemes have corresponding code rates and spectral efficiencies, while the fact that the code rate and spectral efficiency corresponding to the second number of modulation and coding schemes are null values ​​can be understood as meaning that the second number of modulation and coding schemes do not have corresponding code rates and spectral efficiencies. The second number can be determined based on the number of modulation order types. For example, if the first set of modulation and coding schemes includes 6 modulation orders, namely 2, 4, 6, 8, 10, and 12. The second quantity can be 6. The second quantity of modulation and coding schemes includes modulation and coding schemes with a modulation order of 2 and no corresponding code rate and spectral efficiency, modulation and coding schemes with a modulation order of 4 and no corresponding code rate and spectral efficiency, modulation and coding schemes with a modulation order of 6 and no corresponding code rate and spectral efficiency, modulation and coding schemes with a modulation order of 8 and no corresponding code rate and spectral efficiency, modulation and coding schemes with a modulation order of 10 and no corresponding code rate and spectral efficiency, and modulation and coding schemes with a modulation order of 12 and no corresponding code rate and spectral efficiency. In some embodiments, the first set of modulation and coding schemes can be an MCS table, and a second number of modulation and coding schemes in the first set of modulation and coding schemes can be entries in the MCS table with reserved bits for code rate and spectral efficiency. These reserved bits in the entries can be used for repeated transmission. For example, if the network device indicates these reserved bits in the entries, the data sent or received by the terminal is the data after the last encoding, and there is no need to perform channel coding again, reducing transmission latency and energy consumption. In some embodiments, the first modulation and coding scheme set may include 32 modulation and coding schemes, that is, the sum of the first number and the second number can be 32, but is not limited thereto. When the first modulation and coding scheme set includes 32 modulation and coding schemes, the first information can be 5 bits, that is, 5 bits can represent 32 different states or different values. For example, when the first modulation and coding scheme set is presented in the form of an MCS table, the MCS table may include 32 entries. In some embodiments, the first number of modulation coding schemes includes at least one of the following: 3 modulation coding schemes with a modulation order of 2; 3 modulation coding schemes with a modulation order of 4; 7 modulation coding schemes with a modulation order of 6; 5 modulation coding schemes with a modulation order of 8; 5 modulation coding schemes with a modulation order of 10; and 3 modulation coding schemes with a modulation order of 12. In some embodiments, the first modulation and modulation coding scheme set of this disclosure can be designed in the following manner: Optionally, the first modulation scheme set includes one modulation / decoding scheme from the second modulation / decoding scheme set. Assuming 5 bits are used to indicate the modulation / decoding scheme in the first modulation / decoding scheme set, then the first modulation / decoding scheme set contains 32 modulation / decoding schemes that need to be designed. These 32 modulation / decoding schemes include a first number of modulation / decoding schemes and a second number of modulation / decoding schemes. The second number is determined based on the number of modulation order types; if the modulation orders are 2, 4, 6, 8, 10, and 12, the second number is 6, and the first number is 26. Two modulation / decoding schemes from the 26 can be determined first, and then the difference in spectral efficiency between each pair of adjacent indices can be calculated based on the spectral efficiency of these two schemes to determine the spectral efficiency of the remaining 24 modulation / decoding schemes. For example, the two modulation / decoding schemes could be a modulation / decoding scheme with modulation order A1, code rate B1, and spectral efficiency C1, and a modulation / decoding scheme with modulation order A2, code rate B2, and spectral efficiency C2. The former can be selected from the second modulation / decoding scheme set. In the latter case, A2 can be 12, B2 can be the maximum code rate in the second modulation and coding scheme set, and C2 can be calculated based on B2 and 12. The spectral efficiency difference can be calculated based on C1 and C2. For example, the spectral efficiency difference P = (C2 - C1) / 25. Then the spectral efficiencies of the remaining 24 modulation and decoding schemes are C1 + P, C1 + 2 * P, C1 + 3 * P, ..., C1 + 24 * P. The modulation order corresponding to the 24 modulation and coding schemes can be designed, and the code rate can be calculated based on the modulation order and spectral efficiency, thus determining the remaining 24 modulation and coding schemes. For example, the modulation and coding scheme selected from the second modulation and coding scheme set could be a modulation order of 2, a code rate that is the ratio of 120 to 1024, and a spectral efficiency of 0.2344. The ratio of the maximum code rate selected from the second set of modulation and coding schemes to 948 and 1024, based on the modulation order of 12 and the code rate of 948, yields a spectral efficiency of 11.1093 or 11.1094. The difference in spectral efficiency between 11.1094 and 0.2344 is determined to be 0.435. Therefore, the remaining 24 modulation and coding schemes out of the 26 options... The corresponding code rates are 0.6694, 1.1044, 1.5394, ..., 10.6744. The code rate can then be determined based on the designed modulation order. Optionally, the first modulation and coding scheme set includes two modulation and coding schemes from the second modulation and coding scheme set. Assuming 5 bits are used to indicate the modulation and coding schemes in the first modulation and coding scheme set, then the first modulation and coding scheme set contains a total of 32 modulation and coding schemes that need to be designed. These 32 modulation and coding schemes include a first number of modulation and coding schemes and a second number of modulation and coding schemes. The second number is determined based on the number of modulation order types; for modulation orders of 2, 4, 6, 8, 10, and 12, the second number is 6, and the first number is 26. Three modulation and coding schemes from the 26 can be determined first, and then the difference in spectral efficiency between each pair of adjacent indices can be calculated based on the spectral efficiency of these three modulation and coding schemes. For example, the three modulation and coding schemes can be: a modulation and coding scheme with modulation order A1, code rate B1, and spectral efficiency C1, denoted as (A1, B1, C1); a modulation and coding scheme with modulation order A2, code rate B2, and spectral efficiency C2, denoted as (A2, B2, C2); and a modulation and coding scheme with modulation order A3, code rate B3, and spectral efficiency C3, denoted as (A3, B3, C3). (A1, B1, C1) and (A2, B2, C2) can be modulation and coding schemes selected from a second set of modulation and coding schemes. A3 can be 12, B3 can be the maximum code rate in the second set of modulation and coding schemes, and C3 can be calculated based on B3 and 12. The spectral efficiency difference P1 between (A1, B1, C1) and (A2, B2, C2) can be calculated based on C1 and C2. The spectral efficiency difference P2 between multiple modulation and decoding schemes (A2, B2, C2) and (A3, B3, C3) can be calculated based on C2 and C3. For example, the modulation and coding schemes selected from the second set of modulation and coding schemes can be a modulation and coding scheme with a modulation order of 2, a code rate ratio of 120 to 1024, and a spectral efficiency of 0.2344, and a modulation and coding scheme with a modulation order of 10, a code rate ratio of 948 to 1024, and a spectral efficiency of 9.2578, with P1 being 0.4182. The maximum code rate selected from the second set of modulation and coding schemes is a ratio of 948 to 1024.

In some embodiments, taking the second modulation and coding scheme set as shown in Table 4 above, and the first modulation and coding scheme set including three modulation and coding schemes from the second modulation and coding scheme set as an example, the first modulation and coding scheme set can be designed as follows: Assuming that 5 bits are used to indicate the modulation and coding schemes in the first modulation and coding scheme set, then the first modulation and coding scheme set contains a total of 32 modulation and coding schemes that need to be designed. These 32 modulation and coding schemes include a first number of modulation and coding schemes and a second number of modulation and coding schemes. The second number is determined based on the number of modulation order types. If the modulation orders are 2, 4, 6, 8, 10, and 12, the second number is 6, and the first number is 26. Three modulation and coding schemes from the second modulation and coding scheme set can be determined first, for example, three low-bit-rate modulation and coding schemes. Low bit-rate can refer to a bit-rate below a threshold. For example, the three modulation and coding schemes from the second set of modulation and coding schemes include: a modulation and coding scheme with a modulation order of 2, a code rate ratio of 30 to 1024, and a spectral efficiency of 0.0586; a modulation and coding scheme with a modulation order of 2, a code rate ratio of 50 to 1024, and a spectral efficiency of 0.0977; and a modulation and coding scheme with a modulation order of 2, a code rate ratio of 78 to 1024, and a spectral efficiency of 0.1523.
