In the following description, for illustrative purposes, a New Radio (NR) system is described, and NR terminology is used in most of the following description, however, these techniques are applicable to systems other than NR systems, for example, 6th generation (6G) systems. th It is also applicable to 6G (Generation, 6G) communication systems.

[0020] FIG. 1 shows a schematic diagram of a wireless communication system applicable to the embodiment of the present application. The wireless communication system includes a terminal 11 and a network side device 12. Here, the terminal 11 may be called a terminal device or a user terminal (User Equipment, UE), and may be a terminal side device such as a mobile phone, a tablet computer, a laptop computer also called a notebook computer, a personal digital assistant (PDA), a personal digital assistant, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (Mobile Internet Device, MID), a wearable device, a vehicle user equipment (VUE), a pedestrian user equipment (PUE), etc., and the wearable device includes a bracelet, an earphone, glasses, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application.

[0021] In order to facilitate understanding of the embodiments of the present application, the following will first be described.

[0022] In the current NR system, both the Physical Downlink Shared Channel (PDSCH) and the Physical Uplink Shared Channel (PUSCH) adopt AMC technology to determine the modulation scheme and coding rate according to the channel conditions in order to improve the spectrum efficiency of the system. The maximum modulation order supported by the PDSCH in the existing NR system is 8, including a total of four modulation schemes, namely Quadrature Phase Shift Keying (QPSK), 16QAM, 64QAM, and 256QAM. Here, the amount of information transmitted by each modulation symbol of each modulation scheme is 2 bits, 4 bits, 6 bits, and 8 bits, respectively.

[0023] Here, various modulation schemes and coding rates correspond to one Modulation and Coding Scheme (MCS) level. In the current NR release, three MCS tables are defined for PDSCH, and the table contents include MCS index, modulation order, target code rate, and spectral efficiency, as shown in Tables 1, 2, and 3 below. MCS index 0 represents the first MCS level, and MCS index 1 represents the second MCS level, and so on. That is, each MCS index uniquely corresponds to one MCS level.

[0024] [Table 1]

[0025] [Table 2]

[0026] [Table 3]

[0027] In one alternative embodiment, a network side device, for example a base station, notifies a terminal of the determined MCS level by 5-bit indication information in a downlink control information (DCI). The terminal obtains the MCS level used by the base station to transmit data on a PDSCH according to the MCS level indicated by the indication information received by a physical downlink control channel (PDCCH), and determines the modulation order and coding rate corresponding to the MCS level according to the correspondence in Tables 1 to 3, and demodulates and decodes the corresponding data on the PDSCH.

[0028] At the same time, the terminal needs to measure the downlink channel and feed back a channel quality indicator (CQI) to the base station. The CQI feedback is to transmit the recommended modulation scheme and coding rate via the physical uplink shared channel (PUSCH) or physical uplink control channel (PUCCH). The base station determines the MCS corresponding to the uplink / downlink channel according to the CQI fed back by the terminal and a prediction algorithm. In the current NR release, the modulation scheme and coding rate are quantified into 15 CQI levels and defined in a 4-bit table format, i.e., a CQI table, as shown in the following Tables 4, 5, and 6, which correspond to the above Tables 1, 2, and 3, respectively. The modulation schemes, code rates, and spectral efficiencies corresponding to different CQI levels are defined in Tables 4 to 6. Wherein, CQI index 0 represents a first CQI level, and CQI index 1 represents a second CQI level, and so on.

[0029] [Table 4]

[0030] [Table 5]

[0031] [Table 6]

[0032] In order to further improve the spectral efficiency, a higher order modulation scheme is defined in LTE, and the corresponding MCS table and CQI table are shown in Table 7 and Table 8. Table 7 may be abbreviated as MCS table, and includes the MCS index, modulation order and transport block size (TBS) index of PDSCH, and defines the modulation order and TBS index corresponding to different MCS levels during downlink scheduling. Table 8 defines the modulation scheme, code rate and spectral efficiency corresponding to different CQI levels.

[0033] [Table 7]

[0034] [Table 8]

[0035] Hereinafter, the information transmitting and receiving methods provided in the embodiments of the present application will be described in detail with reference to the drawings according to specific embodiments and application cases.

[0036] Please refer to Fig. 2, which is a flow chart of an information transmission method provided in an embodiment of the present application, which is executed by a network side device. As shown in Fig. 2, the method includes the following steps 21 and 22:

[0037] In step 21, a target MCS level corresponding to the terminal transmission is determined.

[0038] In this embodiment, the target MCS level corresponding to the terminal transmission may be understood as the MCS level used for the terminal's downlink reception or uplink transmission. The target MCS level is an MCS level in the first MCS table, and the first MCS table includes an MCS level corresponding to 1024 QAM. That is, the first MCS table includes an MCS level corresponding to a modulation scheme with a modulation order of 10.

[0039] Optionally, the first MCS table at least includes an MCS index corresponding to 1024 QAM, which is a modulation scheme with a modulation order of 10, and a corresponding coding rate and spectral efficiency, and each MCS index uniquely corresponds to one MCS level.

[0040] In step 22, an instruction for determining a target MCS level is sent to the terminal.

[0041] Optionally, the terminal may send, via Radio Resource Control (RRC) signaling, indication information for determining a target MCS level to the terminal, so that the terminal determines the target MCS level according to the indication information and the first MCS table.

[0042] In one embodiment, the network side equipment, for example a base station, may determine a target MCS level corresponding to the terminal transmission according to the first MCS table, for example, determine an MCS level corresponding to the channel to be scheduled by the terminal, and notify the terminal, thus instructing the terminal to determine the modulation scheme and coding rate to be used for the channel to be scheduled according to the MCS level.

[0043] In an embodiment of the present application, the network side device can determine a target MCS level corresponding to terminal transmission, which is an MCS level in a first MCS table including an MCS level corresponding to 1024 QAM, and send instruction information for determining the target MCS level to the terminal, thereby realizing support for 1024 QAM in a corresponding communication system, and solving the problem of limited throughput in applications with high signal-to-noise ratios by supporting higher-order modulation compared with the prior art.

[0044] In an embodiment of the present application, the network side device may receive from the terminal a target CQI, which is a CQI in a first CQI table including a CQI level corresponding to 1024 QAM. The network side device may then determine a target MCS level corresponding to the terminal transmission according to the received CQI and the first MCS table and notify the terminal, thus instructing the terminal to determine the modulation scheme and coding rate used for its downlink reception or uplink transmission according to the MCS level.

[0045] It should be noted that the target CQI may be determined by the terminal according to a channel measurement result and a first CQI table, where the first CQI table at least includes a CQI index corresponding to 1024 QAM, which is a modulation scheme with a modulation order of 10, and a corresponding coding rate and spectral efficiency, and each CQI index uniquely corresponds to one CQI level.

[0046] In an embodiment of the present application, the network side device may indicate at least one MCS table to be used by the terminal through higher layer signaling, for example, through the higher layer parameter mcs-Table or other newly defined higher layer parameters, where the at least one MCS table indicated includes at least an MCS table including an MCS level corresponding to 1024QAM.

[0047] As an optional embodiment, if the at least one MCS table indicated above is at least two first MCS tables, when indicating the first MCS table corresponding to the terminal transmission, the terminal may be directly instructed to select one of the at least two first MCS tables by RRC signaling, or the at least two first MCS tables may be configured by RRC signaling and then the terminal may be instructed to select one of them by a Media Access Control Control Element (MAC CE) or DCI, or the terminal may be instructed to select one of them by different Radio Network Temporary Identity (RNTI) scrambling for the DCI.

[0048] For example, if the at least one MCS table indicated above is two MCS tables including an MCS level corresponding to 1024QAM, i.e., the first MCS table, the RRC signaling may directly instruct the user to select one of the two 1024 QAM MCS tables, or the RRC signaling may configure the two 1024 QAM MCS tables and then instruct the user to select one of them by MAC CE or DCI, or the RRC signaling may instruct the user to select one of them by different RNTI scrambling.

[0049] Here, different 1024 QAM MCS tables, i.e., different first MCS tables, differ in at least one MCS entry. For example, when the at least one specified MCS table includes two first MCS tables, such as MCS Table 1 and MCS Table 2, MCS Table 1 and MCS Table 2 may differ in that, in MCS Table 2, an MCS Entry in MCS Table 1, whose modulation scheme is 1024 QAM, whose target coding rate is 758 / 758.5 / 759, and whose spectral efficiency is 7.4023 / 7.4072 / 7.4121, is replaced with an MCS Entry in MCS Table 2, whose modulation scheme is 256 QAM, whose target coding rate is 948, and whose spectral efficiency is 7.4063.

[0050] Optionally, in an embodiment of the present application, the network side equipment may send first indication information to the terminal, the first indication information being for indicating a first MCS table to be used by the terminal, and the first indication information may be sent by RRC signaling.

[0051] For example, the network side device may use RRC signaling to indicate the first MCS table to be used by the terminal, which may be a 5-bit table, i.e., a table with 32 entries, or a 6-bit table, i.e., a table with 64 entries.

[0052] Optionally, in the embodiment of the present application, the network side device may send second indication information and third indication information to the terminal, where the second indication information is for indicating at least two first MCS tables configured for the terminal, and the third indication information is for indicating a first MCS table to be used by the terminal selected from the at least two first MCS tables. The second indication information may be sent by RRC signaling. The third indication information may be sent by MAC CE or DCI.

[0053] For example, the network side device may indicate multiple first MCS tables to be used by the terminal by RRC signaling, which may include a 5-bit table and a 6-bit table, and may further instruct the terminal to use the 5-bit table or the 6-bit table by the MAC CE, DCI, or the RNTI for scrambling the DCI.

[0054] Further, for example, the network side device may indicate a plurality of first MCS tables to be used by the terminal through RRC signaling, and may further indicate to use one of the plurality of 5-bit tables through MAC CE, DCI, or RNTI for scrambling DCI. For example, when the two first MCS tables indicated through RRC signaling are 5-bit tables and the first MCS table to be used is further indicated through DCI, the 5-bit information may be used to indicate an MCS level corresponding to terminal transmission, and the 1-bit information may be used to indicate a 5-bit MCS table corresponding to the MCS level.

[0055] In an embodiment of the present application, the network side device may indicate at least one CQI table to be used when the terminal performs CQI feedback through higher layer signaling, for example, through higher layer parameter cqi-Table or other newly defined higher layer parameters, where the at least one CQI table indicated includes at least a CQI table including a CQI level corresponding to 1024QAM.

[0056] As an optional embodiment, if the at least one CQI table indicated above is at least two first CQI tables, when indicating the first CQI table corresponding to the terminal transmission, the terminal may directly instruct the terminal to select one of the at least two first CQI tables by RRC signaling, or the at least two first CQI tables may be configured by RRC signaling and then the terminal may instruct the terminal to select one of the tables by MAC CE or DCI, or the terminal may instruct the terminal to select one of the tables by different RNTI scrambling for DCI.

[0057] For example, if the at least one MCS table indicated above is two CQI tables including CQI levels corresponding to 1024QAM, i.e., the first CQI table, the RRC signaling may directly instruct the user to select one of the two 1024 QAM CQI tables, or the RRC signaling may configure the two 1024 QAM CQI tables and then instruct the user to select one of them by MAC CE or DCI, or the RRC signaling may instruct the user to select one of them by different RNTI scrambling.

[0058] Here, at least one CQI entry is different between different 1024 QAM CQI tables, i.e., different first CQI tables. For example, when the at least one specified CQI table includes two first CQI tables, such as CQI table 1 and CQI table 2, CQI table 1 and CQI table 2 may differ in that a CQI entry in CQI table 1, in which the modulation scheme is 1024 QAM, the target coding rate is 758 / 758.5 / 759, and the spectral efficiency is 7.4023 / 7.4072 / 7.4121, is replaced with a CQI entry in CQI table 2, in which the modulation scheme is 256 QAM, the target coding rate is 948, and the spectral efficiency is 7.4063.

[0059] Optionally, in an embodiment of the present application, the network side device may send fourth indication information to the terminal, the fourth indication information being for indicating a first CQI table to be used by the terminal when performing CQI feedback, and the fourth indication information may be sent by RRC signaling.

[0060] Optionally, in the embodiment of the present application, the network side device may send fifth indication information and sixth indication information to the terminal, where the fifth indication information is for indicating at least two first CQI tables configured for the terminal, and the sixth indication information is for indicating a first CQI table selected from the at least two first CQI tables to be used when the terminal performs CQI feedback. The fifth indication information may be sent by RRC signaling, and the sixth indication information may be sent by MAC CE or DCI.

[0061] In the embodiment of the present application, optionally, the first MCS table may be determined according to at least one of the following design principles 1) to 7). 1) Preserve the existing coding rate and spectral efficiency in the existing 1024 QAM CQI table. For example, preserve the existing coding rate and spectral efficiency in the 1024 QAM CQI table of the NR system. 2) Ensure equal spacing for spectral efficiency. 3) Ensure equal spacing of coding speeds. 4) Ensure equal spacing of signal-to-noise ratio. 5) If the encoding rate has a decimal point, process the encoding rate using a first algorithm, where the first algorithm may include any one of rounding up, rounding down, rounding to the nearest integer, retaining one decimal point, etc. 6) If the spectral efficiency has four decimal places remaining, the spectral efficiency is processed using an algorithm that rounds it down to an integer. 7) The relationship between the spectral efficiency and the target coding rate satisfies the relational expression: Spectral efficiency = target coding rate / 1024 * modulation order.
