[0039] In the Release-16 version of NB-IoT technology, the maximum modulation mode supports QPSK modulation, and the peak rate of the QPSK modulation mode is 126.8 kilobits per second. In Release-17, NB-IoT will increase the maximum modulation mode to 16QAM modulation to support higher data transmission rates. However, after the maximum modulation mode is upgraded from QPSK modulation to 16QAM modulation, the existing modulation and coding strategy (MCS) will not be able to meet the modulation and coding needs of the data, and a new modulation and coding strategy MCS is needed. Therefore, in order to support 16QAM modulation of NB-IoT, a new modulation and coding strategy MCS table needs to be defined.

[0040] In one embodiment, the present application provides a configuration method, Figure 2 A flowchart of a configuration method provided by an embodiment of the present application. The method can be applied to the case of determining the MCS of data based on the modulation mode. The method can be executed by the configuration device provided by the present application, which can be implemented by software and / or hardware, and the method is applied in the first communication node.

[0041] As Figure 2 shown, the configuration method provided by the embodiment of the present application mainly includes steps S21 and S22.

[0042] S21, determining a modulation and coding strategy (MCS) set based on a high-layer configuration parameter, wherein the high-layer configuration parameter indicates whether the data transmission supports a 16QAM modulation mode, and the MCS set includes one or more of the following: a first MCS set and a second MCS set.

[0043] S22, configuring the MCS of data based on the MCS set.

[0044] In this embodiment, the first communication node described above can be any one of the base stations described above. In this embodiment, the MCS set can be the correspondence between the MCS, the modulation mode, and the TBS. Specifically, the MCS set contains multiple MCSs, each of which corresponds to a modulation mode and a TBS. In the first MCS set, the highest modulation mode is 16QAM. In the second MCS set, the highest modulation mode is QPSK.

[0045] It should be noted that the first MCS set and the second MCS set are only for distinguishing the sets corresponding to different modulation modes, and do not limit to two actual sets, but also can be two subsets in one set or two different corresponding relations represented in one set. The first MCS set and the second MCS set are only for distinguishing each other, and do not limit the protection scope of the present application.

[0046] In the embodiment, the MCS set can be represented in the form of a table, or can be represented in other manners, which is only described in the embodiment, and is not limited.

[0047] Further, the first communication node determines the MCS table based on the high-layer configuration parameter, and then configures the MCS of data based on the MCS table.

[0048] The high-layer configuration parameter is configured by the first communication node, and the specific configuration manner is not limited in the embodiment.

[0049] In the embodiment, the MCS set includes T MCSs, each of which corresponds to a modulation mode and a TBS, so that one MCS is determined, and the transport block size TBS and the modulation mode of data are determined. When the first communication node configures the MCS of data, one of the T MCSs is selected to encode and modulate the data.

[0050] In the embodiment, the highest modulation mode of the first MCS set is 16QAM, and the highest modulation mode of the second MCS set is QPSK.

[0051] The second MCS set is the MCS set defined in the Release-16 standard protocol (the latest existing version).

[0052] It should be noted that in NB-IoT, the second MCS set satisfies the corresponding relation that MCS indexes 0 to 13 correspond to TBS indexes 0 to 13 respectively, and the modulation mode is QPSK, and the index is a serial number. The transport block size TBS is the bit number of one data transport block, and different TBS indexes correspond to different TBSs in the TBS table, and the TBS table is defined in the existing standard protocol.

[0053] In an exemplary embodiment, the determination of the MCS set based on the high-layer configuration parameter includes:

[0054] In the case that the data transmission supports the 16QAM modulation mode, the MCS set is the first MCS set or the second MCS set.

[0055] In a case where the data transmission does not support the 16QAM modulation mode, the MCS set is a second MCS set.

[0056] In the embodiment, the data transmission supports the 16QAM modulation mode, which means that the 16QAM can be used in the data transmission; and the data transmission does not support the 16QAM modulation mode, which means that only modulation modes with lower orders than the 16QAM, such as the QPSK, can be used in the data transmission.

[0057] Further, in a case where the data transmission supports the 16QAM modulation mode, the MCS of the data is configured based on the first MCS set or the second MCS set, which means that the first MCS set or the second MCS set can be used to configure the MCS of the data in the data transmission.

[0058] Further, in a case where the data transmission does not support the 16QAM modulation mode, the MCS of the data is configured based on the second MCS set, which means that only the second MCS set can be used to configure the MCS of the data in the data transmission.

[0059] In the embodiment, because the modulation order of the 16QAM is high, better channel conditions are required for demodulation, and poor channel conditions are not suitable for 16QAM demodulation. Therefore, when the high-layer configuration parameter P indicates that the data transmission supports the 16QAM, the data transmission can use the first MCS set or the second MCS set to configure the MCS of the data. When the high-layer configuration parameter P indicates that the data transmission does not support the 16QAM, only the second MCS set can be used to configure the MCS of the data.

[0060] In an example embodiment, in a case where the data transmission supports the 16QAM modulation mode, the MCS set is the first MCS set or the second MCS set, including:

[0061] In a case where the data transmission supports the 16QAM modulation mode and the repetition number of the physical shared channel is less than or equal to a preset threshold value, the MCS set is the first MCS set.

[0062] In a case where the data transmission supports the 16QAM modulation mode and the repetition number of the physical shared channel is greater than the preset threshold value, the MCS set is the second MCS set.

[0063] In the embodiment, in a case where the data transmission supports the 16QAM modulation mode, the maximum repetition number of the physical shared channel is greater than or equal to 1024.

[0064] In an example embodiment, the repetition number and the MCS set are indicated by using a repetition number field in the downlink control information.

[0065] Further, in the case that the data transmission supports 16QAM modulation mode, the repetition number and the MCS set are indicated by the repetition number field in the downlink control information.

[0066] The repetition number field contains 4-bit information, has 16 values, each value corresponds to a repetition number and a MCS table,

[0067] Further, the repetition number field contains H values, wherein J values correspond to the first MCS set, and the remaining H-J values correspond to the second MCS set, J is an integer greater than or equal to 1, and H is an integer greater than or equal to 1.

[0068] For example, the value of H is 16.

[0069] In an exemplary embodiment, the first MCS set and the second MCS set satisfy the following relationship:

[0070] For the second MCS set, N+2 TBS indexes are added to remove N TBS indexes, i.e., the TBS indexes of the first MCS set are obtained, wherein the removed TBS indexes are less than or equal to TBS 13, the added TBS indexes are greater than TBS 13, and N is an integer greater than or equal to 0.

[0071] Or,

[0072] Based on the second MCS set, T TBS indexes are added to reserve M TBS indexes, i.e., the TBS indexes of the first MCS set are obtained, wherein the reserved TBS indexes are less than or equal to TBS 13, the added TBS indexes are greater than TBS 13, T+M=16, T and M are both integers greater than or equal to 0.

[0073] In an exemplary embodiment, the removal of N TBS indexes includes one of the following:

[0074] N odd TBS indexes are removed;

[0075] N even TBS indexes are removed;

[0076] N consecutive TBS indexes are removed.

[0077] In an exemplary embodiment, in the first MCS set, the number of MCSs corresponding to 16QAM modulation mode is K, and the number of MCSs corresponding to quadrature phase shift keying (QPSK) modulation mode is L, wherein K is greater than or equal to L, and K and L are both integers greater than or equal to 0. Alternatively, in the first MCS set, only the MCSs of 16QAM modulation mode are included.

[0078] In the embodiment, the number of MCSs of the 16QAM modulation is greater than or equal to the number of QPSK. For example, the first MCS table includes 16 MCSs, and includes two modulation modes, QPSK and 16QAM. In this case, the number of MCSs of the 16QAM modulation is at least 8.

[0079] In an example embodiment, in the first MCS set, the maximum TBS index is TBS21 or TBS22.

[0080] In the embodiment, in the first MCS table, the maximum TBS index is TBS21 or TBS22, and the corresponding modulation mode is 16QAM.

[0081] In an example embodiment, for the band-within-band deployment, when the MCS set is the first MCS set, the configurable TBS index is less than or equal to TBS16.

[0082] In an example embodiment, for the band-within-band deployment, the first MCS set includes 16 MCSs, and the 16 MCSs correspond to TBS indexes TBS0 to TBS15.

[0083] In an example embodiment, for the band-within-band deployment, the first MCS set includes 16 MCSs, and the 16 MCSs correspond to 15 TBS indexes in TBS indexes TBS0 to TBS16, and the 15 TBS indexes include TBS16.

[0084] In an example embodiment, for uplink transmission, in the first MCS set, MCS indexes MCS0 to MCS10 correspond to TBS indexes TBS0 to TBS10 respectively, and the modulation mode corresponding to MCS indexes MCS0 to MCS10 is QPSK modulation; MCS indexes MCS11 to MCS15 correspond to TBS indexes TBS9 to TBS13 respectively, and the modulation mode corresponding to MCS indexes MCS11 to MCS15 is 16QAM modulation.

[0085] In an embodiment, the present application provides a receiving method, Figure 3 A flowchart of a receiving method provided by an embodiment of the present application is shown. The method can be applied to the case of determining data MCS based on modulation mode. The method can be executed by a receiving device provided by the present application, which can be implemented by software and / or hardware. The method is applied in a second communication node.

[0086] As Figure 3 shown, the receiving method provided by the embodiment of the present application mainly includes steps S31 and S32.

[0087] S31, receiving a high layer configuration parameter.

[0088] S32, determining a modulation and coding strategy (MCS) set based on the high layer configuration parameter; wherein the high layer configuration parameter indicates whether the data transmission supports a 16 quadrature amplitude modulation (16QAM) mode, and the MCS set comprises one or more of a first MCS set and a second MCS set.

[0089] In the embodiment, when the second communication node is a user equipment, the high layer configuration parameter is configured and transmitted by the first communication node to the second communication node. The user equipment determines an MCS table based on the high layer configuration parameter, and then configures the MCS of the data based on the MCS table.

[0090] In one exemplary embodiment, determining the MCS set based on the high layer configuration parameter comprises: when the data transmission supports the 16QAM mode, determining the MCS set according to a repetition number field in the downlink control information.

[0091] In one exemplary embodiment, when the data transmission supports the 16QAM mode, determining the MCS set according to the repetition number field in the downlink control information comprises: when the data transmission supports the 16QAM mode and the repetition number field indicates that the repetition number of the physical shared channel is less than or equal to a preset threshold, determining that the MCS set is the first MCS set; and when the data transmission supports the 16QAM mode and the repetition number field indicates that the repetition number of the physical shared channel is greater than the preset threshold, determining that the MCS set is the second MCS set.

[0092] Further, when the data transmission does not support the 16QAM mode, the MCS set is the second MCS set.

[0093] In the embodiment, the data transmission supporting the 16QAM mode means that the 16QAM can be used in the data transmission; and the data transmission not supporting the 16QAM mode means that only a modulation mode with a lower order than the 16QAM, such as the QPSK, can be used in the data transmission.

[0094] In an example embodiment, in the case that the data transmission supports 16QAM modulation mode, the MCS set is determined according to the repetition number field in the downlink control information, including: in the case that the data transmission supports 16QAM modulation mode, and the value of the repetition number field corresponds to the first MCS set, determining that the MCS set is the first MCS set; in the case that the data transmission supports 16QAM modulation mode, and the value of the repetition number field corresponds to the second MCS set, determining that the MCS set is the second MCS set.

[0095] In the embodiment, the MCS table contains T MCSs, each of which corresponds to a modulation mode and a TBS, so that determining one MCS can determine the TBS and the modulation mode of the data.

[0096] In the embodiment, the highest modulation mode of the first MCS table is 16QAM, and the highest modulation mode of the second MCS table is QPSK.

[0097] In the embodiment, in the case that the data transmission supports 16QAM modulation mode, the maximum repetition number of the physical shared channel is greater than or equal to 1024.

[0098] The repetition number field contains 4-bit information, has 16 values, and each value corresponds to a repetition number and an MCS table.

[0099] Further, the repetition number field contains H values, wherein J values correspond to the first MCS set, and the remaining H-J values correspond to the second MCS set, J is an integer greater than or equal to 1, and H is an integer greater than or equal to 1. Alternatively, in the first MCS set, only the MCSs of the 16QAM modulation mode are included.

[0100] For example, the value of H is 16.

[0101] In an example embodiment, the first MCS set and the second MCS set satisfy the following relationship:

[0102] For the second MCS set, N TBS indexes are removed, and N+2 TBS indexes are added, i.e., the TBS indexes of the first MCS set are obtained; wherein the removed TBS indexes are less than or equal to TBS 13, the added TBS indexes are greater than TBS 13, and N is an integer greater than or equal to 0.

[0103] Alternatively,

[0104] Based on the second MCS set, reserve M TBS indexes and add T TBS indexes, to obtain TBS indexes of the first MCS set, wherein the reserved TBS indexes are less than or equal to TBS 13, the added TBS indexes are greater than TBS 13, T+M=16, and T and M are integers greater than or equal to 0.

[0105] In an exemplary embodiment, the removing N TBS indexes comprises one of the following:

[0106] Removing N TBS odd indexes;

[0107] Removing N TBS even indexes;

[0108] Removing N continuous TBS indexes.

[0109] In an exemplary embodiment, in the first MCS set, the number of MCSs corresponding to 16QAM modulation is K, and the number of MCSs corresponding to quadrature phase shift keying (QPSK) modulation is L, wherein K is greater than or equal to L, and K and L are integers greater than or equal to 0.

[0110] In the present embodiment, the number of MCSs of 16QAM modulation is greater than or equal to the number of QPSK. For example, the first MCS table contains 16 MCSs, and contains two modulation modes QPSK and 16QAM, and the number of MCSs of 16QAM modulation is at least 8.

[0111] In an exemplary embodiment, in the first MCS set, the maximum TBS index is TBS21 or TBS22.

[0112] In the present embodiment, in the first MCS table, the maximum TBS index is TBS21 or TBS22, and the corresponding modulation mode is 16QAM.

[0113] In an exemplary embodiment, for the band inside deployment mode, when the MCS set is the first MCS set, the TBS index is less than or equal to TBS16.

[0114] In an exemplary embodiment, for the band inside deployment mode, the first MCS set contains 16 MCSs; wherein the 16 MCSs correspond to TBS indexes TBS0 to TBS15.

[0115] In an exemplary embodiment, for the band inside deployment mode, the first MCS set contains 16 MCSs; wherein the 16 MCSs correspond to 15 TBS indexes among TBS indexes TBS0 to TBS16, and the 15 TBS indexes contain TBS16.

[0116] In an example embodiment, for uplink transmission, in the first MCS set, MCS indexes MCS0 to MCS10 correspond to TBS indexes TBS0 to TBS10 respectively, and the modulation modes corresponding to MCS indexes MCS0 to MCS10 are QPSK modulation modes; MCS indexes MCS11 to MCS15 correspond to TBS indexes TBS9 to TBS13 respectively, and the modulation modes corresponding to MCS indexes MCS11 to MCS15 are 16QAM modulation modes.

[0117] In an application example, the application provides a configuration method of modulation and coding strategy, comprising: determining a modulation and coding strategy (MCS) table based on a high-layer configuration parameter; and configuring an MCS of data based on the MCS table; wherein the high-layer configuration parameter indicates whether a 16QAM mode of quadrature amplitude modulation is supported for data transmission, and the MCS table comprises one or more of the following: a first MCS table and a second MCS table.

[0118] In the embodiment, the MCS table contains T MCSs, each of which corresponds to a modulation mode and a TBS, so that when a MCS is determined, the TBS and the modulation mode of data are determined. When the first communication node configures a MCS for data, one of the T MCSs is selected to code and modulate the data.

[0119] In the embodiment, the highest modulation mode of the first MCS table is 16QAM, and the highest modulation mode of the second MCS table is QPSK.

[0120] The second MCS table is a MCS table defined in a Release-16 standard protocol (the latest existing version). In NB-IoT, there is no specific table for the second MCS table, but the corresponding relationship is met: MCS indexes 0 to 13 correspond to TBS indexes 0 to 13 respectively, and the modulation mode is QPSK, the indexes being serial numbers. The TBS is the number of bits of a data transmission block, and different TBS indexes correspond to different TBSs in a TBS table, which is defined in the existing standard protocol.

[0121] In the embodiment, the first communication node sends the high-layer configuration parameter P to the second communication node, and the high-layer configuration parameter P directly or indirectly indicates whether the data transmission supports 16QAM modulation. Specifically, the high-layer configuration parameter P can be parameter signaling directly indicating whether the data transmission supports 16QAM modulation, or the high-layer configuration parameter P can be parameter signaling indirectly indicating whether the data transmission supports 16QAM modulation, for example, the high-layer configuration parameter P indicates whether the data transmission supports the first MCS table, and if the first MCS table is supported, it is indirectly indicated that the data transmission supports 16QAM modulation, otherwise, it is indirectly indicated that the data transmission does not support 16QAM modulation.

[0122] In the embodiment, the support of 16QAM modulation mode means that the highest 16QAM modulation mode can be used in data transmission, and other modulation modes can also be used; and the non-support of 16QAM modulation mode means that only modulation modes with lower order than 16QAM, for example, QPSK, can be used in data transmission.

[0123] In the embodiment, in the case that the data transmission supports 16QAM modulation mode, the MCS table is the first MCS table or the second MCS table; and in the case that the data transmission does not support 16QAM modulation mode, the MCS table is the second MCS table.

[0124] In the embodiment, because the modulation order of 16QAM is high, better channel conditions are required for demodulation, and poor channel conditions are not suitable for 16QAM demodulation. Therefore, in the case that the data transmission supports 16QAM modulation mode, the data transmission can use the first MCS table to support 16QAM modulation, or use the second MCS table to not support 16QAM modulation. Then, the dynamic switching of the first MCS table and the second MCS table can consider the following two schemes:

[0125] MCS table switching scheme one: in the case that the data transmission supports 16QAM modulation mode, if the repetition number of the physical shared channel is less than or equal to a preset threshold value, the MCS of the data is configured based on the first MCS table; and if the repetition number of the physical shared channel is greater than the preset threshold value, the MCS of the data is configured based on the second MCS table.

[0126] Specifically, in the case that the data transmission supports 16QAM modulation mode, if the repetition number of the physical shared channel is less than or equal to the threshold value, that is, the repetition number is small, it means that the channel condition is good, so the MCS of the data is configured based on the first MCS table; and if the repetition number of the physical shared channel is greater than the threshold value, it means that the channel condition is poor, so the MCS of the data is configured based on the second MCS table. The threshold value is a fixed repetition number or configured by the base station.

[0127] Scheme two: in the case that the data transmission supports 16QAM modulation mode, the repetition number and MCS table are indicated by the repetition number field in the downlink control information. The repetition number field contains H values, among which J values correspond to the first MCS table and the rest H-J values correspond to the second MCS table, and J is greater than or equal to 1.

[0128] Specifically, in the case that the data transmission supports 16QAM modulation mode, the repetition number of the physical shared channel and the selection of the MCS table are jointly indicated by the repetition number field. The repetition number field has H values, each of which corresponds to a repetition number and an MCS table, among which J values correspond to the first MCS table and the rest H-J values correspond to the second MCS table, and the specific correspondence is determined by an indication table of the repetition number field.

[0129] Further, because the high-layer configuration parameter P does not indicate support of 16QAM modulation under large repetition numbers, the J values of the repetition number field can be used to correspond to the first MCS table and small repetition numbers to support 16QAM modulation, and the rest H-J values can be used to correspond to the second MCS table and H-J repetition numbers. For example, when H = 16 and J = 2, the maximum two values of the repetition number field correspond to the first MCS table, and the maximum two values correspond to repetition numbers 1 and 2, respectively, and the smaller 14 values of the repetition number field correspond to the second MCS table, and the smaller 14 values correspond to 14 different repetition numbers.

[0130] In this embodiment, when the base station configures hybrid automatic repeat reQuest (HARQ), if the HARQ initial transmission of the data transmission block adopts a low repetition number, and the size of the data transmission block is greater than TBS 13, and the HARQ initial transmission is not correctly decoded, the base station can adopt the following two operation methods:

[0131] Method one: give up the data transmission block and no longer continue the HARQ retransmission of the transmission block; reselect the repetition number and MCS and configure a new data transmission block.

[0132] Method two: the HARQ retransmission does not increase the repetition number; or the HARQ retransmission increases the repetition number by no more than the maximum repetition number supported by the first MCS table. For the MCS table switching scheme one, the maximum repetition number supported by the first MCS table is the threshold value, and for the MCS table switching scheme two, the maximum repetition number supported by the first MCS table is the maximum repetition number corresponding to the first MCS table in the indication table of the repetition number field.

[0133] In this embodiment, the physical shared channel is a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH).

[0134] In this embodiment, between the first MCS table and the second MCS table, the following relationship is met: for the second MCS table, N transport block size (TBS) indexes are removed, and N+2 TBS indexes are added, i.e., the TBS indexes of the first MCS table are obtained; wherein the removed TBS indexes are less than or equal to TBS 13, the added TBS indexes are greater than TBS 13, and N is an integer greater than or equal to 0.

[0135] Specifically, in NB-IoT, the second MCS table contains 14 MCSs, and MCS indexes 0 to 13 correspond to TBS indexes 0 to 13, respectively. Based on this MCS table, N TBSs are removed, and N+2 TBSs are added, and the added TBS indexes are greater than TBS 13, so that the TBSs contained in the first MCS table are obtained. The first MCS table contains 16 TBSs, corresponding to MCS indexes 0 to 15.

[0136] In this embodiment, the removal of N TBS indexes for the second MCS table can adopt one of the following five schemes:

[0137] TBS removal scheme one: N odd TBS indexes are removed. For example, 6 TBSs including TBS 1, 3, 5, 7, 9, and 11 are removed; and correspondingly, 8 TBSs including TBS 14 to 21 are added.

[0138] TBS removal scheme two: N even TBS indexes are removed. For example, 6 TBSs including TBS 2, 4, 6, 8, 10, and 12 are removed; and correspondingly, 8 TBSs including TBS 14 to 21 are added.

[0139] TBS removal scheme three: N continuous TBS indexes are removed. For example, 7 continuous TBSs including TBS 1 to 7 are removed; and correspondingly, 9 TBSs including TBS 14 to 22 are added.

[0140] TBS removal scheme four: N1 continuous TBS indexes and N2 odd TBS indexes are removed, where N1+N2=N.

[0141] TBS removal scheme five: N1 continuous TBS indexes and N2 even TBS indexes are removed, where N1+N2=N.

[0142] In the embodiment, the relationship between the first MCS table and the second MCS table can also be satisfied: for the second MCS table, M TBS indexes are reserved, and T TBS indexes are added, i.e., the TBS indexes of the first MCS table are obtained, wherein the reserved TBS indexes are less than or equal to TBS 13, the added TBS indexes are greater than TBS 13, T+M=16, and T and M are both integers greater than or equal to 0.

[0143] In the embodiment, the M TBS indexes reserved for the second MCS table can adopt one of the following five schemes:

[0144] TBS removal scheme one: M odd TBS indexes are reserved.

[0145] TBS removal scheme two: M even TBS indexes are reserved.

[0146] TBS removal scheme three: M consecutive TBS indexes are reserved.

[0147] TBS removal scheme four: M1 consecutive TBS indexes and M2 odd TBS indexes are reserved, wherein M1+M2=M.

[0148] TBS removal scheme five: M1 consecutive TBS indexes and M2 even TBS indexes are removed, wherein M1+M2=M.

[0149] In the embodiment, in the first MCS table, the number of MCSs corresponding to the 16QAM modulation mode is K, and the number of MCSs corresponding to the QPSK modulation mode is L, and K is greater than or equal to L. That is, the number of MCSs of the 16QAM modulation is greater than or equal to the number of QPSK. Assuming that the first MCS table contains 16 MCSs and contains two modulation modes QPSK and 16QAM, the number of MCSs of the 16QAM modulation mode is at least 8.

[0150] Further, in the first MCS table, only MCSs using 16QAM modulation can be contained. Assuming that the first MCS table contains 16 MCSs, the number K of MCSs corresponding to the 16QAM modulation mode is equal to 16, i.e., the 16 MCSs are all 16QAM modulation.

[0151] In the embodiment, in the first MCS table, the maximum TBS index is TBS 21 or TBS 22, and the corresponding modulation mode is 16QAM.

[0152] In this embodiment, for NB-IoT In band deployment mode, the maximum TBS supported under 16QAM modulation is no more than TBS 16. Then, for In band mode, the available MCS can adopt one of the following two schemes:

[0153] In band mode scheme one: In band mode shares the same 16QAM MCS table (i.e. the first MCS table) with stand alone mode, but in the 16QAM MCS table, the TBS configurable for In band mode is less than or equal to TBS 16. That is, for In band mode, based on the first MCS table, the MCS with TBS index less than or equal to 16 can be used to configure data, and the MCS with TBS index greater than 16 is not used.

[0154] In band mode scheme two: for In band mode, a 16QAM MCS table dedicated for In band mode is adopted, i.e. the first MCS table for In band mode, which contains 16 MCSs, corresponding to TBS 0 to 15; or, the 16 MCSs correspond to 15 TBSs in TBS 0 to 16, and the 15 TBS indexes contain TBS 16.

[0155] For uplink transmission, in the first MCS table, MCS 0 to 10 correspond to TBS 0 to 10 respectively, and the modulation mode of MCS 0 to 10 is QPSK; MCS 11 to 15 correspond to TBS 9 to 13 respectively, and the modulation mode of MCS 11 to 15 is 16QAM. This is because the maximum TBS supported by uplink 16QAM modulation is TBS 13, so in uplink transmission, the maximum MCS in the first MCS table corresponds to TBS 13.

[0156] In one application embodiment, the present application provides a MCS table for supporting modulation order up to 16QAM, comprising:

[0157] In this embodiment, the second MCS table contains 14 MCSs, i.e. MCS 0 to 13, corresponding to TBS 0 to 13 respectively, and the modulation mode is all QPSK.

[0158] In this embodiment, based on the second MCS table, N odd TBS indexes are removed, and N+2 TBS indexes greater than 13 are added, i.e. the TBS contained in the first MCS table.

[0159] Furthermore, in the first MCS table, the correspondence between the MCS index and the TBS index adopts one of the following two methods:

[0160] MCS-TBS correspondence method 1: For TBS indexes 0 to 13, remove the N TBS odd indexes, which are indexes I1, I2...I N , the remaining TBS indexes J1, J2...J 14-N In the first MCS table, MCS indexes J1, J2...J 14-N Corresponding to TBS index J1, J2...J 14-N , MCS index I1, I2...I N Corresponding to N TBS indices greater than 13, MCS indices 14 and 15 correspond to 2 TBS indices greater than 13.

[0161] MCS-TBS correspondence method 2: In the first MCS table, TBS corresponds to MCS 0 to 15 in descending order.

[0162] In this embodiment, in the first MCS table, the number of MCSs corresponding to the 16QAM modulation mode is K, the number of MCSs corresponding to the QPSK modulation mode is L, and K is greater than or equal to L.

[0163] In this embodiment, in the first MCS table, the largest TBS index is TBS 21 or TBS 22, and the corresponding modulation mode is 16QAM.

[0164] In this embodiment, for the In-band mode, based on the first MCS table, an MCS with a TBS index less than or equal to 16 can be used to configure data, and an MCS with a TBS index greater than 16 is not used.

[0165] In this embodiment, the modulation order of QPSK is 2, and the modulation order of 16QAM is 4.

[0166] Optionally, in Example 1 of the first MCS table: N is equal to 6, 6 TBS odd indexes in TBS 0 to 13 are removed, namely TBS 1, 3, 5, 7, 9, and 11, and 8 TBSs are added, namely TBS14 to 21; the TBSs in the first MCS table correspond to MCS 0 to 15 in order from small to large.

[0167] In Example 1 of the first MCS table, an MCS less than TBS 10 corresponds to QPSK modulation, and an MCS greater than or equal to TBS 10 corresponds to 16QAM modulation, as shown in Table 1; or, an MCS less than TBS 12 corresponds to QPSK modulation, and an MCS greater than or equal to TBS 12 corresponds to 16QAM modulation.

In the MCS table, MCSs 0 to 10 correspond to TBSs 0 to 10, respectively, and the modulation mode is QPSK; MCSs 11 to 15 correspond to TBSs 9 to 13, respectively, and the modulation mode is 16QAM, as shown in Table 16.

[0270] Table Sixteen

[0271]

[0272]

[0273] In one application embodiment, the present application provides a MCS table indication method, comprising:

[0274] When the data transmission supports 16QAM modulation, if the repetition number of the physical shared channel is less than or equal to a threshold value, the MCS of the data is configured based on a first MCS table; if the repetition number of the physical shared channel is greater than the threshold value, the MCS of the data is configured based on a second MCS table.

[0275] In this embodiment, the highest modulation mode of the first MCS table is 16QAM.

[0276] In this embodiment, the second MCS table is the MCS table defined in the Release-16 standard protocol. In NB-IoT, there is no specific table for the second MCS table, but the corresponding relationship is met: MCS indexes 0 to 13 correspond to TBS indexes 0 to 13, and the modulation mode is QPSK, and the index is the serial number.

[0277] In this embodiment, whether the data transmission supports 16QAM modulation is determined according to a high-layer configuration parameter P. When the data transmission supports 16QAM, if the repetition number of the physical shared channel is less than or equal to a threshold value, the MCS of the data is configured based on a first MCS table, and the highest modulation mode of the first MCS table is 16QAM; if the repetition number of the physical shared channel is greater than the threshold value, the MCS of the data is configured based on a second MCS table, and the highest modulation mode of the second MCS table is QPSK. The physical shared channel is PDSCH or PUSCH.

[0278] In this embodiment, the threshold value is a fixed repetition number.

[0279] In NB-IoT, the repetition number field contains 4-bit information, has 16 values, and indicates 16 repetition numbers. The value of the repetition number field and the repetition number corresponding relationship is shown in Table Seventeen. Assuming that the threshold value is 8, in the case of physical shared channel repetition number being 1, 2, 4, and 8, the data is configured based on the first MCS table; in the case of physical shared channel repetition number being greater than or equal to 16, the data is configured based on the second MCS table.

[0280] Table Seventeen

[0281]

[0282] In one application embodiment, the application provides still another MCS table indication method, comprising:

[0283] When data transmission supports 16QAM modulation, the repetition number and MCS table are indicated by a repetition number field in downlink control information. The repetition number field contains 16 values, of which J values correspond to a first MCS table, and the remaining 16-J values correspond to a second MCS table, J being greater than or equal to 1.

[0284] In this embodiment, the highest modulation mode of the first MCS table is 16QAM.

[0285] In this embodiment, the second MCS table is the MCS table defined in the Release-16 standard protocol. In NB-IoT, there is no specific table for the second MCS table, but the corresponding relationship is met: MCS indexes 0 to 13 correspond to TBS indexes 0 to 13, and the modulation mode is QPSK, and the index is the serial number.

[0286] In this embodiment, whether data transmission supports 16QAM modulation is determined according to a high-layer configuration parameter P. When data transmission supports 16QAM, the repetition number of the physical shared channel and the selection of the MCS table are jointly indicated by the repetition number field. The repetition number field contains 4 bits of information, with 16 values, each value corresponding to a repetition number and an MCS table, of which J values correspond to a first MCS table, and the remaining 16-J values correspond to a second MCS table. The physical shared channel is PDSCH or PUSCH.

[0287] In one specific example of this embodiment, the maximum 4 values of the repetition number field correspond to the first MCS table, supporting 16QAM modulation, and the repetition numbers corresponding to the 4 values are 1, 2, 4, and 8, respectively; the remaining 12 values correspond to the second MCS table, not supporting 16QAM modulation, as shown in Table Eighteen. Among them, MCS table index 0 is the second MCS table, and MCS table index 1 is the first MCS table.

[0288] Table Eighteen

[0289]

[0290] In another specific example of the embodiment, two values of the repetition number field correspond to the first MCS table, and the four values of the repetition number field correspond to 1 and 2, respectively; the remaining 14 values of the repetition number field correspond to the second MCS table, as shown in Table Nineteen. In Table Nineteen, the order of the rows can be exchanged, as shown in Table Twenty and Table Twenty-One.
