[0275] In some embodiments, the first information is used by terminal 101 to determine the first MCS table used for data transmission.

[0276] In some embodiments, data transmission includes PUSCH transmission and / or PDSCH transmission. For example, the first information is used by terminal 101 to determine the first MCS table used for PUSCH; as another example, the first information is used by terminal 101 to determine the first MCS table used for PDSCH.

[0277] In some embodiments, the first information is used to enable a first MCS table group among a plurality of MCS table groups configured by the terminal.

[0278] In some embodiments, multiple MCS table groups are divided according to at least one of the following: service type, highest modulation order, and waveform.

[0279] In some embodiments, multiple MCS tables are divided according to business type to obtain multiple MCS table groups.

[0280] In some embodiments, different service types may correspond to different MCS table groups. For example, perception services correspond to MCS table group A, and voice services correspond to MCS table group B.

[0281] In some embodiments, multiple MCS tables are divided according to the highest modulation order to obtain multiple MCS table groups.

[0282] In some embodiments, MCS tables with the same highest modulation order can be grouped into one MCS table group. For example, Table 1 and Table 3 can be grouped into one MCS table group.

[0283] In some embodiments, multiple MCS tables are divided according to the waveform to obtain multiple MCS table groups.

[0284] In some embodiments, different waveforms may correspond to different MCS table groups. For example, CP-OFDM waveforms correspond to MCS table group C, and DFT-s-OFDM waveforms correspond to MCS table group D.

[0285] In some embodiments, an MCS table group may include one MCS table, and an MCS table group may also include multiple MCS tables. This disclosure does not limit the scope of the embodiments.

[0286] In some embodiments, terminal 101 may predefine multiple MCS table groups.

[0287] In some embodiments, the name of the first information is not limited, and it may be, for example, “table group enable information”.

[0288] In some embodiments, terminal 101 predefines multiple MCS table groups, and network device 102 enables one of the MCS table groups by sending first information. For example, the MCS table groups predefine by terminal 101 include MCS table group A, MCS table group B, MCS table group C, and MCS table group D, and the first information enables MCS table group C.

[0289] In some embodiments, network device 102 determines a first MCS table group based on the service type of data transmission.

[0291] In some embodiments, network device 102 determines a first MCS table group based on the waveform during data transmission.

[0292] In some embodiments, after determining the first MCS table group, the network device 102 sends the first information to the terminal 101 based on the first MCS table group to enable the first MCS table group.

[0293] Step S2202: The terminal determines the first MCS table from multiple MCS tables in the first MCS table group according to the configured first association relationship.

[0294] In some embodiments, the first association includes the correspondence between different third information and the MCS table.

[0295] In some embodiments, the third information includes at least one of the following: DCI format, Control Resource Set (CORESET), Search Space (SS), and Radio Network Temporary Identity (RNTI).

[0296] In some embodiments, the DCI format includes one of the following formats: DCI format 1-1, DCI format 1-2, DCI format 0-1, DCI format 0-2, DCI format 2-3, and DCI format 2-X.

[0297] In some embodiments, when the third information is in DCI format, the first association relationship includes the correspondence between different DCI formats and MCS tables.

[0298] In some embodiments, the first association relationship includes the correspondence between DCI format 1-1 and MCS table, the correspondence between DCI format 1-2 and MCS table, the correspondence between DCI format 0-1 and MCS table, the correspondence between DCI format 1-2 and MCS table, the correspondence between DCI format 2-3 and MCS table, and the correspondence between DCI format 2-X and MCS table.

[0299] In some embodiments, when the third information is CORESET, the first association includes the correspondence between different CORESETs and the MCS table.

[0300] In some embodiments, CORESET includes a public CORESET and a UE-specific CORESET. The public CORESET is identified as CORESET 0, and the UE-specific CORESET is identified as CORESET 1 to 11.

[0301] In some embodiments, the first association relationship includes the correspondence between each CORESET identifier and an MCS table. For example, CORESET 0 corresponds to MCS table A, CORESET 1 corresponds to MCS table B, CORESET 2 corresponds to MCS table E, and other CORESET identifiers will not be described further.

[0302] In some embodiments, when the third information is SS, the first association relationship includes the correspondence between different SS and MCS tables.

[0303] In some embodiments, SS includes public SS (CSS) and UE-specific SS. Public SS includes at least one of Type0-PDCCH CSS, Type0A-PDCCH CSS, Type1-PDCCH CSS, Type2-PDCCH CSS, and Type3-PDCCH CSS.

[0304] In some embodiments, the first association relationship includes the correspondence between each SS and an MCS table. For example, Type0-PDCCH CSS corresponds to MCS table M, Type0A-PDCCH CSS corresponds to MCS table N, Type1-PDCCH CSS corresponds to MCS table K, and Type3-PDCCH CSS corresponds to MCS table G.

[0305] In some embodiments, when the third information is an RNTI, the first association relationship includes the correspondence between different RNTIs and MCS tables.

Other types of RNTIs will not be described further.

[0308] In some embodiments, terminal 101 may predefine a first association relationship.

[0309] In some embodiments, terminal 101 may be pre-configured with a first association relationship.

[0310] In some embodiments, network device 102 can configure a first association relationship for terminal 101. For example, network device 102 can send fifth information to terminal 101, the fifth information including the first association relationship.

[0311] In some embodiments, when the third information is RNTI, PDSCH does not include semi-persistent scheduling (SPS PDSCH).

[0312] It should be noted that the MCS table corresponding to the third information mentioned above is for illustrative purposes only, and this disclosure does not limit it.

[0313] In some embodiments, after receiving the first information sent by the network device 102, the terminal 101 can determine the first MCS table from the first MCS table enabled by the first information.

[0314] In some embodiments, the first MCS table can be determined by at least one of the following:

[0315] Based on the format of the DCI received by terminal 101 and the first association relationship, determine the first MCS table;

[0316] Based on the CORESET where DCI is located and the first association, determine the first MCS table;

[0317] Based on the SS where DCI is located and the first association, determine the first MCS table;

[0318] The first MCS table is determined based on the RNTI and the first association relationship received by terminal 101.

[0319] In some embodiments, if the first association relationship includes the correspondence between different DCI formats and MCS tables, then the terminal 101 can determine the first MCS table from multiple MCS tables in the first MCS table group based on the received DCI format and the first association relationship. For example, if the received DCI format is DCI format 1-2, then the first MCS table is determined to be MCS table B; if the received DCI format is DCI format 2-X, then the first MCS table is determined to be MCS table F.

[0320] In some embodiments, if the first association relationship includes the correspondence between different CORESETs and MCS tables, then the terminal 101 can detect the CORESET where the DCI is located, and determine the first MCS table from multiple MCS tables in the first MCS table group based on the CORESET where the DCI is located and the first association relationship. For example, if the CORESET where the DCI is located is CORESET 0, then the first MCS table is determined to be MCS table A; if the CORESET where the DCI is located is CORESET 2, then the first MCS table is determined to be MCS table E.

[0321] In some embodiments, if the first association relationship includes the correspondence between different SSs and MCS tables, then the terminal 101 can detect the SS where the DCI is located, and determine the first MCS table from multiple MCS tables in the first MCS table group based on the SS where the DCI is located and the first association relationship. For example, if the SS where the DCI is located is Type0-PDCCH CSS, then the first MCS table is determined to be MCS table M; if the SS where the DCI is located is Type3-PDCCH CSS, then the first MCS table is determined to be MCS table G.

[0322] In some embodiments, if the first association relationship includes the correspondence between different RNTIs and MCS tables, the terminal 101 can determine the first MCS table from multiple MCS tables in the first MCS table group based on the received RNTI and the first association relationship. For example, if the RNTI is a system information RNTI, the first MCS table is determined to be MCS table X; if the RNTI is a cell RNTI, the first MCS table is determined to be MCS table Z.

[0323] In some embodiments, if the first MCS table group includes multiple MCS tables, the terminal 101 receives the second indication information sent by the network device 102, and step S2202 can be omitted.

[0324] In some embodiments, network device 102 sends first indication information to terminal 101, and terminal 101 can determine the MCS table used for data transmission based on the first indication information.

[0325] In some embodiments, the second indication information may be MAC-CE or DCI. For example, the first MCS form may be indicated by MAC-CE, or by DCI.

[0326] In some embodiments, if the first MCS table group includes an MCS table, the MCS table in the first MCS table group can be used as the first MCS table, and step S2202 can be omitted.

[0327] In some embodiments, network device 102 sends third instruction information to terminal 101.

[0328] In some embodiments, the third indication information is used to indicate whether an MCS with a modulation order greater than or equal to a first threshold is supported.

[0329] In some embodiments, the first threshold is 10, meaning that the supported modulation schemes are up to 1024QAM.

[0330] In some embodiments, the third indication information is used for the terminal 101 to determine the first MCS table according to the method of step S2202.

[0331] In some embodiments, terminal 101 receives third indication information sent by network device 102.

[0332] In some embodiments, if the third indication information indicates support for an MCS with a modulation order greater than or equal to a first threshold, then terminal 101 executes step S2202. For example, if the first threshold is 10 and the third indication information indicates support for an MCS with a modulation order greater than or equal to 10, then terminal 101 may execute step S2202.

[0333] In some embodiments, the third indication information may be MAC-CE or DCI. For example, MAC-CE indicates whether an MCS with a modulation order greater than or equal to a first threshold is supported, and DCI indicates whether an MCS with a modulation order greater than or equal to the first threshold is supported.

[0334] Step S2203: Network device 102 sends fourth information to terminal 101.

[0335] In some embodiments, terminal 101 receives fourth information sent by network device 102, but is not limited thereto. Terminal 101 may also receive fourth information sent by other entities, in which case step S2203 may be omitted.

[0336] In some embodiments, terminal 101 obtains the fourth information specified by the protocol, in which case step S2203 can be omitted.

[0337] In some embodiments, the terminal 101 obtains the fourth information from the upper layer(s), in which case step S2203 can be omitted.

[0338] In some embodiments, the terminal 101 processes the information to obtain the fourth information, in which case step S2203 can be omitted.

[0339] In some embodiments, the fourth information is used to indicate the MCS index.

[0340] In some embodiments, the terminal 101 determines the MCS used for data transmission based on the first MCS table and the MCS index, that is, determines the row corresponding to the MCS index in the first MCS table.

[0341] In some embodiments, the fourth information may be indicated by DCI.

[0342] In some embodiments, the MCS index may also be referred to as the MCS index value or the MCS value.

[0343] In some embodiments, terminal 101 receives fourth information sent by network device 102, determines the MCS corresponding to the MCS index from the first MCS table, and obtains the MCS used for data transmission. For example, if the first MCS table is Table 1 and the MCS index is 5, then the MCS corresponds to the 6th row of Table 1: modulation order is 2, and target code rate is 379.

[0344] Using the above method, when the first MCS table group includes one MCS table, the terminal can determine the first MCS table based on the MCS tables included in the first MCS table group, which improves the efficiency of determining the MCS table; when the first MCS table group includes multiple MCS tables, the terminal can determine the first MCS table based on third information. In this way, the process of determining the MCS table is simplified by determining the MCS table dynamically.

[0358] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0359] Figure 3 is a flowchart illustrating a communication method according to an embodiment of the present disclosure. As shown in Figure 3, this embodiment of the present disclosure relates to a communication method that can be executed by a terminal 101. The method may include:

[0360] Step S3101: Determine the first MCS table used for data transmission.

[0361] The optional implementations of step S3101 can be found in the optional implementations of steps S2102a, S2102b, and S2102c in Figure 2A, and step S2202 in Figure 2B, as well as other related parts in the embodiments involved in Figures 2A and 2B, which will not be repeated here.

[0362] In some embodiments, terminal 101 determines the first MCS table used for data transmission based on first information.

[0363] In some embodiments, the first information is used to configure the MCS table corresponding to different second information, and the second information includes at least one of the following: waveform, modulation level, and service type.

[0364] In some embodiments, the first information is used to enable a first MCS table group among a plurality of MCS table groups configured in the terminal, wherein the plurality of MCS table groups are divided according to at least one of the following: service type, highest modulation order, waveform.

[0365] In some embodiments, the first information may be predefined or preconfigured, or it may be indicated by the network device.

[0366] It should be noted that the explanation of the first information can be found in the optional implementation of step S2101 in Figure 2A and step S2201 in Figure 2B, which will not be repeated here.

[0367] In some embodiments, the MCS table can be semi-statically configured. Different waveforms, modulation levels, or services are configured using RRC signaling.

[0368] In one implementation, semi-static configuration can be supported. The configured MCS table is directly indicated via DCI; if no MCS table is configured, a default MCS table is defined.

[0369] Optionally, multiple MCS tables can be configured for different waveforms in the uplink.

[0370] Optionally, multiple MCS tables can be configured for the downlink.

[0371] In another implementation, multiple MCS table group configurations can be predefined, and one of the configuration tables can be enabled via RRC signaling, including the case where a group corresponds to only one table.

[0372] Alternatively, the grouping principle can be based on categories such as service, highest modulation order, etc.

[0373] Optionally, for an enabled configuration containing more than one MCS, the MCS table to be used can be selected by combining the information in the following embodiments.

[0374] In some embodiments, the actual service and channel conditions of the terminal are dynamically variable, and the MCS table can support dynamic configuration indication.

[0375] In one implementation, the distinction is based on different DCI formats, meaning that different DCI formats correspond to different numbers of DCI bits.

[0376] In another implementation, the distinction is based on CORESET / SS. By predefining the correspondence between CORESET / SS and MCS tables, the MCS table is distinguished based on the CORESET / SS where the detected DCI is located.

[0377] In another implementation, the distinction is based on different RNTIs, that is, different RNTIs indicate different MCS tables or newly introduced tables.

[0378] Optionally, this does not apply to SPS-PDSCH.

[0379] In another implementation, the indication in MAC-CE or DCI indicates whether a specific service / modulation level actually corresponds to a higher-order MCS scheme.

[0380] Optionally, based on the above configuration grouping, the actual MCS table used can be dynamically indicated.

[0381] In some embodiments, the specific MCS index is indicated by the DCI bits.

[0382] 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.

[0383] 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.

[0384] 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).
