[0106] In some embodiments, the access network device 102-1 may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. By adopting the CU-DU structure, the protocol layer of the access network device can be separated. 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, which is centrally controlled by the CU. However, this is not the only possibility.

[0112] In this embodiment of the disclosure, "modulation coding method" is also referred to as "modulation method".

[0113] The downlink PDSCH transmission can correspond to at least one of the following modulation and coding scheme (MCS) tables:

[0114] The corresponding MCS table is MCS_64QAM;

[0115] The corresponding MCS table for 256QAM is MCS_256QAM;

[0116] The MCS table MCS_URLLC corresponds to Ultra-reliable and Low Latency Communications (URLLC) services;

[0117] The corresponding MCS table for 1024QAM is MCS_1024QAM.

[0119] In some embodiments, the CQI index to be reported can be determined based on at least one modulation scheme among QPSK, 16QAM, 64QAM and 256QAM, according to Table 2 below.

[0120] In some embodiments, the CQI index to be reported can be determined based on at least one modulation scheme among QPSK, 16QAM, 64QAM, 256QAM and 1024QAM, as shown in Table 4 below.

[0121] Table 1

[0122] Table 2

[0123] Table 3

[0124] Table 4

[0125] In some embodiments, unless otherwise specified, based on time-independent and frequency-independent observation intervals, the terminal needs to derive the highest CQI index for each CQI value reported in uplink slot n that satisfies the following conditions:

[0126] A single PDSCH transport block has a combination of modulation scheme, target code rate, and transport block size corresponding to the CQI index, and occupies a set of downlink physical resource blocks called CSI reference resources, with a receive transport block error probability of no more than 0.1 or 0.00001.

[0127] Specifically, if the higher-layer parameter cqi table in the Channel State Information Report Configuration (CSI-ReportConfig) is configured as "Table 1" or "Table 2", or if the higher-layer parameter cqi table in CSI-ReportConfig is configured as "Table 4", then the probability of receiving transport block error does not exceed 0.1.

[0128] If the high-level parameter cqi-Table in CSI-ReportConfig is configured with "table3", the probability of receiving transport block errors will not exceed 0.00001.

[0129] In some embodiments, if the higher-layer parameter timeRestrictionForChannelMeasurements in CSI-ReportConfig is set to "notConfigured", the terminal should derive the channel measurement values ​​used to calculate the CSI values ​​reported in uplink slot n based only on the Non-Zero Power Channel State Information Reference Signal (NZP CSI-RS) no later than the CSI reference resource associated with the CSI resource settings.

[0130] The channel measurement may include, but is not limited to, at least one of CQI, precoding matrix indicator (for indicating the optimal precoding matrix), rank indicator (for indicating the number of channel transmission layers), layer indicator (for indicating the source of the data stream), and received signal strength indicator.

[0131] If the higher-layer parameter timeRestrictionForChannelMeasurements is set to "Configured", the terminal should derive the channel measurements used to calculate the CSI reported in uplink slot n (if cell DTX is active) based only on the most recent (no later than CSI reference resource) in the cell discontinuous transmission (DTX) activity period of the serving cell, as well as the NZP CSI-RS associated with the CSI resource settings on the serving cell.

[0132] If the higher-layer parameter timeRestrictionForInterferenceMeasurements is set to “notConfigured”, the terminal should perform interference measurements no later than the CSI reference resource associated with the CSI resource settings, based solely on Channel State Information Interference Measurement (CSI-IM) and / or NZP CSI-RS, to obtain the interference measurement value used to calculate the CSI value reported in uplink slot n.

[0133] If the higher-layer parameter timeRestrictionForInterferenceMeasurements is set to “Configured”, the UE should calculate the CSI value reported in uplink slot n based on the scenario of the most recent CSI reference resource, no later than the CSI reference resource, during the cell DTX activation period of the serving cell (if the cell DTX is activated), and the interference measurement CSI-IM and / or NZP CSI-RS related to the CSI resource settings on the serving cell.

[0134] If the high-level parameter based on subband reporting cqi bits (cqi-BitsPerSubband) is not configured in CSI-ReportConfig, then for each subband index s, a 2-bit subband differential CQI value can be used to report the CQI of the subband.

[0135] Wherein, subband offset level(s) = subband CQI index(s) - wideband CQI index.

[0136] The subband offset level can refer to the difference between the CQI index on different subbands and the wideband CQI index.

[0137] The correspondence between the subband offset level and the subband differential CQI value is shown in Table 6.

[0138] Table 6

[0139] In some embodiments, as services continue to grow, higher-order modulation methods can be used to increase service rates.

[0140] 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:

[0141] In step S2100, terminal 101 and network device 102 determine the first CQI table.

[0142] In some embodiments, the first CQI form may be predefined in the protocol. Correspondingly, terminal 101 and network device 102 determine the first CQI form based on the protocol agreement.

[0143] In some embodiments, the first CQI table supports at least a first modulation scheme, and in this embodiment, the modulation order of the first modulation scheme is greater than or equal to 12.

[0144] In one example, the first modulation scheme may include, but is not limited to, 4096QAM with a modulation order of 12, or other higher-order modulation schemes.

[0145] In some embodiments, the second CQI form can be expanded to obtain the first CQI form.

[0146] In one example, the second CQI table does not support the first modulation scheme, but supports at least one of several second modulation schemes. That is, the second CQI table does not include any first entry corresponding to the first modulation scheme, but includes second entries corresponding to at least one second modulation scheme.

[0147] In one example, the second CQI table can be the aforementioned Table 4, or of course other tables, which are not limited in this disclosure.

[0148] In some embodiments, considering that the number of bits occupied by the CQI index determined by the terminal 101 based on the second CQI table, such as Table 4, is 4, the number of bits occupied by the CQI index determined by the terminal 101 based on the first CQI table can also be 4, thereby reducing the amount of modification to the protocol and avoiding the terminal 101 reporting that the CQI index occupies too many bits.

[0149] In some embodiments, the first CQI table may also support multiple second modulation schemes, wherein the modulation order of any of the second modulation schemes is less than 12.

[0150] In one example, the modulation order of the second modulation scheme can be, for example, 2, 4, 6, 8, or 10.

[0151] For example, the second modulation scheme with a modulation order of 2 may include, but is not limited to, QPSK.

[0152] For example, the second modulation scheme with a modulation order of 4 may include, but is not limited to, 16QAM.

[0153] For example, the second modulation scheme with a modulation order of 6 may include, but is not limited to, 64QAM.

[0154] For example, the second modulation scheme with a modulation order of 8 may include, but is not limited to, 256QAM.

[0155] For example, the second modulation scheme with a modulation order of 10 may include, but is not limited to, 1024QAM.

[0156] In some embodiments, the first CQI table may include M second entries and N first entries. M and N are both positive integers, and the sum of M and N is less than or equal to 16, thereby ensuring that the CQI index reported by terminal 101 occupies 4 bits.

[0157] In one example, the second entry is the entry corresponding to any of the second modulation schemes.

[0158] In one example, the first entry is the entry corresponding to the first modulation scheme.

[0159] In one example, an entry can refer to any row in the table except for the header (i.e., the row containing the CQI index, modulation scheme, code rate, and SE). Table 4, for example, contains 16 entries.

[0160] In some embodiments, the S second entries in the first CQI table corresponding to the same second modulation scheme can be the same as the S third entries, wherein the S third entries are the S entries in the second CQI table corresponding to the same second modulation scheme as the S second entries. The second CQI table does not support the first modulation scheme, but supports at least one of the multiple second modulation schemes, and S is a positive integer less than or equal to M.

[0161] In one example, the S third entries can be any of the following in the second CQI table: (corresponding to the same second modulation scheme as the S second entries and) the first S entries sorted in descending order of spectral efficiency SE; (corresponding to the same second modulation scheme as the S second entries and) the first S entries sorted in ascending order of spectral efficiency SE; (corresponding to the same second modulation scheme as the S second entries and) the S entries whose spectral efficiency SE is an arithmetic sequence.

[0162] For example, if S is 3, M is 14, and the second modulation scheme is QPSK, the three second entries corresponding to QPSK in the first CQI table can be the same as the three third entries corresponding to QPSK in the second CQI table.

[0163] Specifically, the three third entries in the second CQI table can be the first three entries in the second CQI table sorted in descending order of spectral efficiency (SE) (and corresponding to QPSK). Alternatively, the three third entries in the second CQI table can be the first three entries in the second CQI table sorted in ascending order of spectral efficiency (SE) (and corresponding to QPSK). Alternatively, the three third entries in the second CQI table can be three entries in the second CQI table whose spectral efficiency (SE) forms an arithmetic sequence (and corresponds to QPSK).

[0164] In some embodiments, the first CQI form may be obtained in any of the following ways:

[0165] Method 1: Determine the first CQI table based on the second CQI table.

[0166] Method 1-1 can be adopted by first method, selecting M third entries from the second CQI table, and obtaining the first CQI table based on the selected M third entries and the newly generated N first entries.

[0167] For example, the first approach may include, but is not limited to, any of the following: selecting at least one third entry for each second modulation scheme in descending order of spectral efficiency (SE); selecting at least one third entry for each second modulation scheme in ascending order of SE; or selecting the third entries corresponding to the various second modulation schemes respectively at equal intervals of SE.

[0168] For example, there are 3 entries corresponding to the second modulation method QPSK in Table 4. We can prioritize selecting the third entry with a high SE. For example, we can select the entries with SE of 0.877 and 0.377 as the two second entries corresponding to QPSK in the first CQI table.

[0169] For example, there are 4 entries for the second modulation mode 64QAM in Table 4. We can prioritize the third entry with a low SE. For example, we can select the entries with SE of 3.3223 and 3.9023 as the two second entries for 64QAM in the first CQI table.

[0170] For example, for the entries corresponding to various second modulation methods in Table 4, they are selected at equal intervals according to SE, thus selecting M second entries. Suppose that the third entries with SE values ​​of 0.377, 1.4766, 2.4063, 3.3223, ... are selected as the second entries in the first CQI table.

[0171] It is understandable that when selecting the second item by equal intervals of SE, it may not be possible to ensure that the difference between the two adjacent SEs is exactly equal. In this case, the third item can be selected by making the difference between the two adjacent SEs approximately equal.

[0172] The above is merely an illustrative example, and this disclosure does not limit the method of selecting M second entries from the second CQI table.

[0173] In one example, after selecting M second entries from the second CQI table, N first entries can be generated.

[0174] For example, N first entries can be generated at equal intervals according to SE.

[0175] For example, N first entries can be generated in a manner that is approximately equally spaced according to SE.

[0176] For example, N first entries can be generated based on at least one code rate corresponding to the first modulation scheme.

[0177] This disclosure does not limit the method of generating N first entries.

[0178] In one example, to improve the availability of the first CQI table for multiple modulation schemes, the number of entries for each modulation scheme in the first CQI table can be made equal.

[0179] For example, if the first CQI table includes 6 modulation schemes, with 1 first modulation scheme and 5 second modulation schemes, then the number of entries for each modulation scheme can be 3.

[0180] Alternatively, to improve the availability of the first CQI table for multiple modulation schemes, the difference in the number of entries corresponding to any two modulation schemes can be less than or equal to a second value. The second value can be a positive integer. That is, the number of entries corresponding to each modulation scheme is approximately equal. The second value can be agreed upon by the protocol.

[0181] For example, the first CQI table includes 6 modulation methods, of which there is 1 first modulation method, 5 second modulation methods, and the second value is 1. Then, the number of entries corresponding to one second modulation method can be 3, the number of entries corresponding to another second modulation method can be 4, and the number of entries corresponding to the first modulation method can be 2.

[0182] For example, the first CQI form may be referred to as "Table 5", as shown below.

[0183] Table 5

[0184] Method 1-2 allows you to delete N third entries and add N first entries in the second CQI table using the second method, thus obtaining the first CQI table.

[0185] The second method includes, but is not limited to, any of the following: if the number of entries corresponding to the second modulation method is less than or equal to the first value, the entries corresponding to the second modulation method are retained; if the number of entries corresponding to the second modulation method is greater than the first value, at least one entry corresponding to the second modulation method is deleted in descending order of SE; if the number of entries corresponding to the second modulation method is greater than the first value, at least one entry corresponding to the second modulation method is deleted in ascending order of SE; if the number of entries corresponding to the second modulation method is greater than the first value, entries corresponding to multiple second modulation methods are retained according to equally spaced SEs.

[0186] For example, if the number of third entries corresponding to a second modulation scheme is less than or equal to the first value, then all third entries corresponding to that second modulation scheme can be retained.

[0187] For example, if the first value is 3, and the number of third entries corresponding to the second modulation method with a modulation order of 2 in the second CQI table is 3, then we can retain the corresponding 3 third entries and obtain 3 second entries.

[0188] For example, if the number of third entries corresponding to a second modulation scheme is greater than the first value, at least one entry corresponding to the second modulation scheme can be deleted in descending order of SE. That is, the third entries with higher SE are deleted first.

[0189] For example, if the first value is 3, and the number of third entries corresponding to the second modulation method with a modulation order of 6 in the second CQI table is 4, then the third entry with the highest SE can be deleted, and the remaining 3 third entries can be used as 3 second entries.

[0190] For example, if the number of third entries corresponding to a second modulation scheme is greater than the first value, at least one entry corresponding to the second modulation scheme can be deleted in ascending order of SE. That is, the third entries with lower SE are deleted first.

[0191] For example, if the first value is 3, and the number of third entries corresponding to the second modulation method with a modulation order of 6 in the second CQI table is 4, then the third entry with the lowest SE can be deleted, and the remaining 3 third entries can be used as 3 second entries.

[0192] For example, if the number of third entries corresponding to the second modulation scheme is greater than the first value, the third entries corresponding to various second modulation schemes can be retained according to equally spaced SEs. That is, the SEs in the retained third entries can form an arithmetic sequence or an approximately arithmetic sequence, thereby obtaining the corresponding second entries.

[0193] The above is merely an illustrative example, and this disclosure does not limit the scheme for retaining the third entry in the second CQI form.

[0194] Furthermore, N newly generated first entries can be added to the second CQI table after deleting N third entries.

[0195] For example, N first entries can be generated at equal intervals according to SE.

[0196] For example, N first entries can be generated in a manner that is approximately equally spaced according to SE.

[0197] For example, N first entries can be generated based on at least one code rate corresponding to the first modulation scheme.

[0198] The specific process has been described in the foregoing embodiments and will not be repeated here.

[0199] For example, assuming the second CQI table is Table 4, the first CQI table obtained after expansion can also be called "Table 4" or "the new Table 4".

[0200] For example, in Table 4, retain the 3 entries corresponding to QPSK, retain the 2 entries corresponding to 16QAM, retain the 3 entries corresponding to 64QAM, delete the entry with a lower SE corresponding to 64QAM (e.g., SE 3.9023), retain the 3 entries corresponding to 256QAM, delete the entry with a lower SE corresponding to 256QAM (e.g., SE 5.5547), retain the 2 entries corresponding to 1024QAM, and add 2 entries corresponding to 4096QAM. The resulting new Table 4 is as follows:

[0201] New Table 4

[0202] Method 2: Determine the first CQI table based on the first MCS table.

[0203] In one example, M second entries and N first entries can be selected from the first MCS table to obtain the first CQI table.

[0204] The first MCS table is an MCS table that simultaneously supports multiple second modulation methods and first modulation methods.

[0205] For example, the SEs in the first MCS table form an arithmetic sequence.

[0206] Selecting M second entries and N first entries from the first MCS table allows for either an equal number of entries or approximately equal numbers of entries for each modulation scheme. Correspondingly, the resulting first CQI table can be called "Table 5," or "Table 4," or "the new Table 4," as shown below:

[0207] For example, M second entries and N first entries can be selected from the first MCS table, and the selection can be made at equal SE intervals, so that the SEs in the resulting first CQI table form an arithmetic sequence.

[0208] Of course, by selecting M second entries and N first entries from the first MCS table, for higher-order modulation schemes (such as 256QAM, 1024QAM, 4096QAM), the selection can be made according to equal SE intervals, so that some SEs in the resulting first CQI table form an arithmetic sequence, as shown in the table below:

[0209] It is understood that the first CQI table supporting the first modulation scheme provided in this disclosure may include at least one row of the above table.

[0210] In one example, the precision of the SE in the first CQI table can be 0.001.

[0211] In one example, the precision of the SE in the first CQI table can be 0.0001.

[0212] In one example, the bitrate N in the first CQI table can be in the range of [N-0.5, N+0.5].

[0213] It is understandable that, for example, when the bitrate in the first CQI table above is 842.5, the bitrate can be rounded down or up, that is, the bitrate can be 843 or 842.

[0214] The above is merely an illustrative example, and this disclosure does not limit the method of determining the first CQI form.

Further, terminal 101 can determine a first CQI index corresponding to the channel quality assessment result from the aforementioned first CQI indexes. For example, the code rate is determined based on the channel quality assessment result, thereby determining a first CQI index to be reported from the aforementioned first CQI indexes based on the terminal implementation.

[0239] For example, the better the channel quality assessment result indicates, the larger the selected first CQI index can be.

[0240] In step S2104, terminal 101 sends the first CQI index to network device 102.

[0241] In some embodiments, terminal 101 may add a first CQI index to the CSI report and send the CSI report to the network device.

[0279] In the above embodiments, while supporting higher-order first modulation methods, the service rate is significantly improved and the availability is high.

[0280] The above process is further illustrated with examples below.

[0281] In this embodiment of the disclosure, a CQI table that supports higher-order modulation methods is provided, and the specific method is as follows:

[0282] Define a new CQI form.

[0283] Method 1: Define a new CQI table based on at least the existing CQI table.

[0284] Four bits are used for CQI indication.

[0285] Supported modulation schemes include at least one of the following: QPSK, 16QAM, 64QAM, 256QAM, 1024QAM, and 4096QAM.

[0286] Corresponding table definition:

[0287] For QPSK: Keep 3 entries;

[0288] For 16QAM: retain 2 entries;

[0289] For 64QAM: retain 3 entries; for example, remove 1 entry with a low SE, #7;

[0290] For 256QAM: Keep 3 entries. For example, remove one entry with a low SE, #10;

[0291] For 1024QAM: retain 2 entries;

[0292] For 4096QAM: Add 2 entries.

[0293] Regarding the protection method for table definitions:

[0294] 1) Each entry can be protected by a corresponding SE range.

[0295] 2) The newly defined table may include at least one row from either the aforementioned Table 5 or the new Table 4.

[0296] 3) For SE, the precision is 0.001 or 0.0001.

[0297] 4) The applicable range for each bit rate N is: [N-0.5, N+0.5].

[0298] Method 2: Determine the newly defined CQI table based on the MCS table.

[0299] Four bits are used for CQI indication.

[0300] Among them, the supported modulation methods are at least one of the following: QPSK, 16QAM, 64QAM, 256QAM, 1024QAM, and 4096QAM.

[0301] The corresponding table definition: The corresponding CQI table is generated by selecting the MCS table designed by equal interval SE.

[0302] Regarding the protection method for table definitions:

[0308] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0309] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0310] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
