Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G). In some embodiments, the PDSCH modulation scheme supports up to 1024QAM, and the PUSCH modulation scheme supports up to 256QAM. The MCS tables for downlink PDSCH transmission applications include four tables: MCS_64QAM, MCS_256QAM, MCS_URLLC, and MCS_1024QAM, corresponding to Tables A through D below. In some embodiments, the MCS tables used for PUSCH transmission include three tables for CP-OFDM waveforms: MCS_64QAM, MCS_256QAM, and MCS_URLLC. For DFT-s-OFDM waveforms, dedicated MCS tables are redefined for 64QAM and URLLC, while for MCS tables supporting 256QAM, the tables used for PDSCH transmission can be used. In some embodiments, the tables used for DFT-s-OFDM waveforms may include at least one of the following: an MCS index table for PUSCH using transform precoding and 64QAM, an MSC index table 2 for PDSCH, and an MSC index table 4 for PDSCH. In some of the embodiments described below, the MCS index table for PUSCH using transform precoding and 64QAM may be referred to as the second MCS table, the MSC index table 2 for PDSCH may be referred to as the third MCS table, and the MSC index table 4 for PDSCH may be referred to as the fourth MCS table. In some embodiments, the MCS index table (i.e., the second MCS table) for PUSCH using transform precoding and 64QAM can be as shown in Table A below: Table A Optionally, as shown in Table A, the second MCS table includes 2 data entries corresponding to the q-order modulation mode, 8 data entries corresponding to the 2-order modulation mode, 7 data entries corresponding to the 4-order modulation mode, 11 data entries corresponding to the 6-order modulation mode, and reserved entries corresponding to the q-order, 2-order, 4-order, and 6-order modulation modes, respectively. In some embodiments, the MSC index table 2 (i.e., the third MCS table) for PDSCH can be as shown in Table B below: Table B Optionally, as shown in Table B, the third MCS table includes 5 data entries corresponding to the second-order modulation scheme, 6 data entries corresponding to the fourth-order modulation scheme, 9 data entries corresponding to the sixth-order modulation scheme, 8 data entries corresponding to the eighth-order modulation scheme, and reserved entries corresponding to the second-order, fourth-order, sixth-order, and eighth-order modulation schemes, respectively. In some embodiments, the MSC index table 4 for PDSCH can be as shown in Table C below: Table C Optionally, as shown in Table C, the third MCS table includes 3 data entries corresponding to the 2nd order modulation mode, 3 data entries corresponding to the 4th order modulation mode, 9 data entries corresponding to the 6th order modulation mode, 8 data entries corresponding to the 8th order modulation mode, 4 data entries corresponding to the 10th order modulation mode, and reserved entries corresponding to the 2nd, 4th, 6th, 8th and 10th order modulation modes respectively. In the table above, "MCS Index (IMCS)" indicates the index of each entry, "Modulation Order (Qm)" indicates the modulation order corresponding to each entry, and "Target code Rate R x" indicates the modulation order of each entry.

[1024] "" is used to indicate the coding rate corresponding to each entry, and "Spectral efficiency" is used to indicate the spectral efficiency corresponding to each entry. It is worth noting that in the table above, q = 1 or q = 2. When q = 1, the corresponding data entry or reserved entry can be used for first-order modulation, and when q = 2, the corresponding data entry or reserved entry can be used for second-order modulation. Furthermore, in the various entries of the MCS table, reserved entries can refer to entries without specified coding rate and spectral efficiency, while entries other than reserved entries can be referred to as data entries. In some embodiments, as shown in Tables A to C above, no MCS table can simultaneously support the scheduling of all modulation schemes under DFT-s-OFDM, which directly causes scheduling limitations in the network. For example, when the network's configured MCS table supports 256QAM, it will select the corresponding downlink MCS table (i.e., Table B or Table C) for PUSCH transmission, thus making it impossible to actually schedule uplink using pi / 2bpsk modulation. Figure 2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, the embodiments of the present disclosure relate to a communication method, which includes: Step S2101: The terminal sends PUSCH to the network device. In some embodiments, the terminal determines that PUSCH transmission is performed using a DFT-s-OFDM waveform and sends PUSCH to the network device according to the first modulation and coding scheme MCS table and / or MCS index. The first MCS table and / or MCS index are used to determine the modulation scheme and coding rate used for transmitting PUSCH. In some embodiments, the network device receives the PUSCH sent by the terminal based on a first MCS table and / or MCS index. In some embodiments, a first coding rate and a first spectral efficiency used for PUSCH transmission are determined based on a first MCS table and / or an MCS index. Optionally, the first coding rate and the first spectral efficiency are determined based on a first MCS table. In some embodiments, the first MCS table is used for PUSCH transmission of the DFT-s-OFDM waveform. In some embodiments, the first MCS table includes multiple entries, each of which may be used to indicate information such as the corresponding modulation order, coding rate, and spectral efficiency, but is not limited thereto. In some embodiments, the MCS index may be determined by the network device and indicated to the terminal, or it may be determined by the terminal and reported to the network device. In some embodiments, the network device sends a first indication to the terminal, the first indication being used to indicate an MCS index. The MCS index may be used to indicate an entry in a first MCS table. Optionally, the terminal determines the entry based on the first MCS table and the first indication. The indicated MCS index determines the first coding rate and the first spectral efficiency. In some embodiments, the network device determines a first coding rate and a first spectral efficiency, and sends a first indication to the terminal. The first indication is used to indicate an MCS index, which can be used to determine the first coding rate and the first spectral efficiency. The terminal can determine the first coding rate and the first spectral efficiency from a first MCS table based on the MCS index. For example, if the first MCS table is the table shown in Table A in the following embodiment, and if the MCS index indicated by the first indication sent by the network device is 10, the terminal can determine the first coding rate as 340, the first spectral efficiency as 1.3281, and perform PUSCH transmission based on the first coding rate and the first frequency efficiency. In some embodiments, the terminal may also determine the MCS index itself, for example, by determining the modulation order, the first coding rate, and the first spectral efficiency from a first MCS table. Optionally, the terminal sends a second indication to the network device, which indicates the MCS index determined by the terminal. The network device can determine the first coding rate and the first spectral efficiency adopted by the terminal based on the MCS index and the first MCS. For example, the second indication includes the index value corresponding to any entry in the first MCS table. Optionally, the network device determines the modulation order, the first coding rate, and the first spectral efficiency adopted by the terminal from the first MCS table according to the second indication. In some embodiments, the first MCS table supports modulation and demodulation for each modulation order from the first modulation method to the second modulation method. Optionally, the first modulation method is q-order modulation, where q = 1 or q = 2. Optionally, the second modulation method is any one of an 8th-order modulation method, a 10th-order modulation method, or a 12th-order modulation method. In some embodiments, the first modulation scheme may refer to the modulation scheme corresponding to the lowest modulation order supported by the first MCS table. Optionally, the second modulation scheme may refer to the modulation scheme corresponding to the highest modulation order supported by the first MCS table. Optionally, the first-order modulation scheme may be, for example, pi / 2BPSK modulation, the second-order modulation scheme may be, for example, QPSK modulation, the fourth-order modulation scheme may be, for example, 16QAM modulation, the sixth-order modulation scheme may be, for example, 64QAM modulation, the eighth-order modulation scheme may be, for example, 256QAM modulation, the tenth-order modulation scheme may be, for example, 1024QAM modulation, and the twelfth-order modulation scheme may be, for example, 4096 modulation, but is not limited thereto. For example, the first MCS table can be used for modulation and demodulation of modulation schemes from q-order to 12-order. That is, the terminal can perform pi / 2BPSK modulation, QPSK modulation, 16QAM modulation, 64QAM modulation, 256QAM modulation, 1024QAM modulation, and 4096QAM modulation based on the first MCS table. Correspondingly, the network device can demodulate the PUSCH sent by the terminal based on the first MCS table. In some embodiments, the first MCS table may be determined based on a candidate table, wherein the first MCS table may include at least one entry from the candidate table. Optionally, the candidate table may be an MCS table that has been predefined in the protocol. In some embodiments, the candidate table can be any of the following: a second MCS table, which is an MCS index table for PUSCH using transform precoding and 64QAM; a third MCS table, which is an MSC index table 2 for PDSCH; and a fourth MCS table, which is an MSC index table 4 for PDSCH. The second MCS table can be referred to as Table A above, the third MCS table can be referred to as Table B above, and the fourth MCS table can be referred to as Table C above. Optionally, the first MCS table may retain one or more entries from the candidate table, such as retaining some data entries and / or reserved entries from the second MCS table. Optionally, the first MCS table may also add data entries and reserved entries based on the candidate table, such as adding data entries corresponding to the 8th-order modulation scheme and reserved entries corresponding to the 8th-order modulation scheme to the second MCS table. In some embodiments, the first MCS table has 31 entries. In some embodiments, the first MCS table satisfies at least one of the following: The spectral efficiency ranges from 0.2344 to 0.3066 for the q-order modulation scheme. The spectral efficiency range for the second-order modulation scheme is 0.3770 to 1.3262. The spectral efficiency range for the fourth-order modulation scheme is 1.3281 to 2.5703. The spectral efficiency range for the 6th-order modulation scheme is 2.7305 to 5.5547. The spectral efficiency range for the 8th-order modulation scheme is 5.5547 to 7.4063. The spectral efficiency range for the 10th-order modulation scheme is 7.8662 to 9.2578. The spectral efficiency range for the 12th-order modulation scheme is 9.8750 to 11.1093, or 9.8750 to 11.1094. Optionally, when determining the first MCS table based on the candidate table, the candidate table can be adjusted based on the above requirements so that the spectral efficiency range corresponding to each adjustment method meets the requirements and uniformly covers the rate and spectral efficiency range. In some embodiments, the actual coding rate range when the terminal sends a PUSCH according to the first coding rate entry is [N-0.5, N+0.5], where N represents the first coding rate, which is the coding rate determined according to the first MCS table and / or MCS index; and / or, In some embodiments, the actual spectral efficiency precision of the terminal when transmitting PUSCH according to the first spectral efficiency is 0.001 or 0.0001, where the first spectral efficiency is the spectral efficiency determined according to the first MCS table and / or MCS index. For example, if the network device indicates the use of the coding rate and spectral efficiency corresponding to the entry with index 10 in Table A of the following embodiments. When transmitting a PUSCH, the coding rate actually used by the terminal to transmit the PUSCH can be 336 or 345 or any other coding rate between 335 and 345, and / or the spectral efficiency actually used by the terminal to transmit the PUSCH can be 1.3281 or 1.328. In some embodiments, the second modulation scheme can be an 8th-order modulation scheme, the candidate table is a second MCS table, and the first MCS table includes at least one of the following: The second MCS table contains two data entries corresponding to the q-order modulation scheme; The second MCS table contains 6 data entries corresponding to the second-order modulation scheme; The second MCS table contains 5 data entries corresponding to the 4th-order modulation scheme; The second MCS table contains 9 data entries corresponding to the 6th order modulation scheme; The 6 data entries corresponding to the 8th-order modulation scheme; A reserved entry corresponding to the 8th-order modulation scheme; A reserved entry corresponding to the q-order modulation method.

Optionally, the first MCS table also includes a reserved entry for the 4th-order modulation scheme and a reserved entry for the 6th-order modulation scheme. Optionally, the first MCS table may retain two data entries corresponding to the q-order modulation scheme in the second MCS table. Optionally, the first MCS table includes six data entries corresponding to the second-order modulation schemes in the second MCS table. This can be obtained by removing any two data entries corresponding to the second-order modulation schemes from the second MCS table. Alternatively, one entry with lower spectral efficiency (e.g., second lowest) and one entry with higher spectral efficiency (e.g., second highest) from the second MCS table corresponding to the second-order modulation schemes can be removed, and the remaining six data entries can be used as data entries in the first MCS table. The data entries corresponding to the fourth-order and sixth-order modulation schemes in the first MCS table can be obtained by processing the second MCS table in the same way, which will not be elaborated here. For example, the first MCS table can be shown in Table a below: Table a In some embodiments, the second modulation scheme can be an 8th-order modulation scheme, the candidate table is a third MCS table, and the first MCS table includes at least one of the following: Two data entries corresponding to the q-order modulation scheme; The third MCS table contains four data entries corresponding to the second-order modulation scheme; The third MCS table contains 6 data entries corresponding to the 4th-order modulation scheme; The third MCS table contains 8 data entries corresponding to the 6th order modulation scheme; The third MCS table contains 8 data entries corresponding to the 8th order modulation scheme; A reserved entry corresponding to the q-order modulation method.

This can be obtained by removing any four data entries corresponding to the second-order modulation schemes from the second MCS table. For example, the second, fourth, sixth, and eighth data entries with the lowest spectral efficiency in the second MCS table can be removed, and the remaining four data entries can be used as the data entries in the first MCS table. The data entries corresponding to the fourth-order and sixth-order modulation schemes in the first MCS table can be obtained by processing the second MCS table in the same way, which will not be elaborated here.
