[0105] Table 1

[0106] Table 2

[0107] Table 3

[0108] Table 4

[0109] 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:

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] Wherein, subband offset level(s) = subband CQI index(s) - wideband CQI index.

[0120] The subband offset level can refer to the difference between the CQI index on different subbands and the wideband CQI index.

[0121] The correspondence between the subband offset level and the subband differential CQI value is shown in Table 6.

[0123] In some embodiments, as services continue to grow, higher-order modulation methods can be used to increase service rates.

[0125] In step S2101, network device 102 sends the first signaling to terminal 101.

[0126] In some embodiments, the first signaling is used to semi-statically configure or dynamically indicate a first CQI form corresponding to a CQI report among multiple CQI forms.

[0127] In some embodiments, terminal 101 receives a first signaling sent by network device 102, but is not limited thereto. Terminal 101 may also receive a first signaling sent by other entities, such as relay devices or other terminals. In this case, step S2101 may be omitted.

[0130] In some embodiments, the terminal 101 performs processing to obtain the first signaling, in which step S2101 is omitted.

[0131] In some embodiments, the terminal 101 autonomously implements the function indicated by the first signaling, or the above function is a default or default value, in which case step S2101 is omitted.

[0132] In some embodiments, terminal 101 may acquire first signaling when it is in a connected state, an idle state, or an inactive state.

[0133] In some embodiments, terminal 101 may acquire first signaling if channel measurement needs to be performed.

[0136] In some embodiments, when the modulation scheme is the first modulation scheme, the terminal 101 acquires the first signaling.

[0137] In some embodiments, when terminal 101 determines that multiple CQI tables exist in the protocol, it obtains and sends the first signaling.

[0138] In some embodiments, network device 102 may send a first signaling when it is necessary for terminal 101 to perform channel measurements and report a channel measurement report.

[0139] In some embodiments, network device 102 may send a first signaling to terminal 101 via a wireless connection with terminal 101.

[0140] In some embodiments, when the network device 102 needs to increase the service rate, it sends a first signaling to the terminal 101.

[0141] In some embodiments, when the modulation method is a first modulation method, the network device 102 sends a first signaling to the terminal 101.

[0142] In some embodiments, when the network device 102 determines that multiple CQI tables exist in the protocol, it sends a first signaling to the terminal 101.

[0143] In some embodiments, the first signaling may include, but is not limited to, at least one of Radio Resource Control (RRC), Media Access Control-Control Element (MAC CE), and Downlink Control Information (DCI).

[0144] In some embodiments, the first signaling can be RRC signaling, and the network device 102 can configure the first CQI table through the higher-level parameter cqi-Table in CSI-ReportConfig.

[0145] In some embodiments, the first signaling can be MAC CE or DCI, and the network device 102 can configure the first CQI table through the CQI parameters in MAC CE or DCI.

[0146] In some embodiments, the first signaling includes RRC signaling and DCI. The network device 102 can provide multiple CQI tables through CSI-ReportConfig, and then indicate one of the multiple tables through DCI. The terminal 101 determines the CQI table indicated by DCI as the first CQI table.

[0147] In some embodiments, the first signaling includes RRC signaling and MAC CE. The network device 102 can provide multiple CQI tables through CSI-ReportConfig and then indicate one of the multiple tables through MAC CE. The terminal 101 determines the CQI table indicated by DCI as the first CQI table.

[0148] In some embodiments, the name of the first signaling is not limited, and may be, for example, “CQI form configuration information” or “CQI form instruction information”.

[0149] In some embodiments, the first CQI form is a new form added to the protocol, such as Table 5 below.

[0150] Table 5

[0151] In some embodiments, the first CQI table is a modification of an existing table in the protocol, such as modifying Table 4 to obtain a new Table 4 as follows:

[0152] New Table 4

[0153] The above is merely an illustrative example, and this disclosure does not limit the table name or determination method of the first CQI.

[0154] In some embodiments, step S2101 is an optional step. For example, when the total number of CQI forms is 1, step S2101 may not be executed.

[0155] In one example, the total number of CQI forms is 1, and the CQI form can be represented as shown in the table below:

[0156] Alternatively, the CQI form can be as follows:

[0157] The above is merely an illustrative example, and this disclosure does not limit the content or determination method of the CQI form.

[0158] In step S2102, terminal 101 determines the first CQI table.

[0159] In some embodiments, the first CQI table supports at least a first modulation scheme.

[0160] In some embodiments, the first CQI form is one of a plurality of CQI forms, and the terminal 101 may determine the first CQI form based on the first signaling.

[0161] For example, if the high-level parameter cqi-Table in CSI-ReportConfig is configured as "Table 5" or "Table 4" (i.e., the new Table 4 mentioned above), then terminal 101 can determine that the first CQI table is either Table 5 or the new Table 4 mentioned above.

[0162] In some embodiments, if the total number of CQI forms is 1, then terminal 101 can determine that the first CQI form is the only CQI form.

[0163] In step S2103, terminal 101 determines the CQI report.

[0164] In some embodiments, terminal 101 may use relevant technologies to determine the specific content of the CQI report.

[0165] In one example, a CQI report may include, but is not limited to, at least one of the following: CQI index; precoding matrix; modulation scheme, etc.

[0166] In some embodiments, terminal 101 may perform channel quality assessment based on at least one of the physical downlink channels, such as PDSCH and PDCCH, sent by network device 102, to obtain a channel quality assessment result. The specific content of the CQI report is then determined based on this channel quality assessment result.

[0167] In step S2104, terminal 101 sends a CQI report to network device 102.

[0168] In some embodiments, network device 102 receives a CQI report sent by terminal 101, but is not limited thereto. Network device 102 may also receive a CQI report sent by other entities, such as relay devices or other network devices, in which case step S2104 may be omitted.

[0169] In some embodiments, network device 102 obtains a CQI report as defined by the protocol, in which case step S2104 is omitted.

[0170] In some embodiments, network device 102 obtains CQI reports from upper layer(s), in which case step S2104 is omitted.

[0171] In some embodiments, network device 102 processes data to obtain a CQI report, in which step S2104 is omitted.

[0172] In some embodiments, the network device 102 autonomously implements the function indicated by the CQI report, or the above function is the default or default, in which case step S2104 is omitted.

[0173] In some embodiments, terminal 101 may include the CQI report in the CSI report and send the CQI report to network device 102 when reporting the CSI report.

[0174] In some embodiments, when CQI reporting is required, terminal 101 sends a CQI report to network device 102.

[0175] In some embodiments, when a CSI report needs to be reported, the terminal 101 sends a CQI report to the network device 102.

[0176] In some embodiments, when it is necessary to report the channel quality assessment results, the terminal 101 sends a CQI report to the network device 102.

[0177] In some embodiments, network device 102 determines channel quality based on CQI reports in order to schedule subsequent data transmission.

[0178] In some embodiments, the CQI report includes a broadband CQI index.

[0179] In one example, if there are multiple CQI tables, the number of bits occupied by the wideband CQI index can be 4.

[0180] In one example, if the total number of CQI tables is 1, the number of bits occupied by the wideband CQI index can be greater than or equal to 5.

[0181] In some embodiments, the CQI report may also include a sub-band CQI index.

[0182] In one example, if there are multiple CQI tables and the subband CQI index is reported differentially, the number of bits occupied by the subband CQI index can be 2. The correspondence between the subband offset level and the reported subband CQI index (i.e., the subband differential CQI value) is shown in Table 6.

[0183] In one example, if there are multiple CQI tables and the subband CQI index does not use differential reporting, the number of bits occupied by the subband CQI index can be equal to the number of bits occupied by the wideband CQI index, which is also 4.

[0184] In one example, if the total number of CQI tables is 1, and the subband CQI index uses differential reporting, then the number of bits occupied by the subband CQI index can be 2. The correspondence between the subband offset level and the reported subband CQI index (i.e., the subband differential CQI value) is shown in Table 6.

[0185] In one example, if the total number of CQI tables is 1, and the subband CQI index uses differential reporting, then the number of bits occupied by the subband CQI index can be 2. The correspondence between the subband offset level and the reported subband CQI index (i.e., the subband differential CQI value) is shown in Table 7.

[0186] Table 7

[0187] Wherein, n1, n2, and n3 are all positive integers. For example, n1 can be less than n2, and n1 can be equal to n3. The specific values ​​are not limited in this disclosure.

[0188] For example, if n1 = n3 = 2 and n2 = 3, then Table 7 is as follows:

[0189] In one example, if the total number of CQI tables is 1, and the subband CQI index uses differential reporting, then the number of bits occupied by the subband CQI index can be 3. The correspondence between the subband offset level and the reported subband CQI index (i.e., the subband differential CQI value) is shown in Table 8.

[0190] Table 8

[0191] In one example, if the total number of CQI tables is 1 and the subband CQI index does not use differential reporting, then the number of bits occupied by the subband CQI index can be equal to the number of bits occupied by the wideband CQI index, both being greater than or equal to 5.

[0192] The above is merely an illustrative example, and this disclosure does not limit the number of bits occupied by the broadband CQI index and the subband CQI index.

While supporting high-order first modulation modes, it significantly improves service rates and has high availability.

[0206] Figure 3A is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 3A, the present disclosure relates to an information transmission method, which can be executed by a terminal 101, and includes the following steps:

[0207] Step S3101: Determine the first CQI form.

[0208] In some embodiments, reference can be made to the steps in other embodiments described before or after this embodiment, such as step S2102 in FIG2 and its optional implementation, and other related parts in the specification, which will not be repeated here.

[0209] Step S3102: Determine the CQI report.

[0210] In some embodiments, reference can be made to the steps in other embodiments described before or after this embodiment, such as step S2103 in FIG2 and its optional implementation, as well as other related parts in the specification, which will not be repeated here.

[0213] In some embodiments, steps S3101 to S3103 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0214] In some embodiments, the execution order of steps S3101 to S3103 is not limited.

[0215] In the above embodiments, while supporting higher-order first modulation methods, the service rate is significantly improved, and the reliability of CQI reporting is enhanced, resulting in high availability.

[0216] Figure 3B is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 3B, the present disclosure relates to a communication method, which can be executed by a network device 102, and includes the following steps:

[0217] Step S3201: Obtain the CQI report.

[0218] In some embodiments, reference can be made to the steps in other embodiments described before or after this embodiment, such as step S2104 in FIG2 and its optional implementation, as well as other related parts in the specification, which will not be repeated here.

[0219] In the above embodiments, while supporting higher-order first modulation methods, the service rate is significantly improved and the availability is high.

[0220] The above process is further illustrated with examples below.

[0221] In this embodiment of the disclosure, CSI estimation and reporting can be performed based on a configured CQI table, as detailed below:

[0222] Method 1 allows you to extend the cqi_Table configuration in CSI-ReportConfig to create a CQI table corresponding to 4096QAM for CQI reports.

[0223] The number of bits reported by the broadband CQI is 4; the number of bits reported by the subband is 2 or 4.

[0224] Method 2 eliminates the need for the cqi_Table parameter configuration.

[0225] The number of bits reported by the broadband CQI is 5;

[0226] The number of bits reported by the subband CQI can be one of the following two types:

[0227] Method 2-1: If cqi-BitsPerSubband is configured in CSI-ReportConfig, then each subband CQI is reported as 5 bits.

[0228] Method 2-2: If cqi-BitsPerSubband is not configured in CSI-ReportConfig, then the subband CQI is reported differentially.

[0229] According to relevant protocols, 2 bits can be used;

[0230] Alternatively, the number of bits reported by the subband CQI differential is 3 bits, and the subband offset level and subband differential CQI value correspond to Table 8.

[0231] In the above embodiments, higher-order modulation can be supported, which improves the reliability of CQI reporting.

[0232] 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.

[0233] 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.

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.

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).
