Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a transmission configuration method, apparatus, terminal, network-side equipment, and medium. Background Technology

[0002] Currently, the modulation and coding scheme (MCS) index can support the transmission of some modulation schemes.

[0003] For example, taking π / 2 binary phase shift keying (π / 2BPSK) transmission as an example, only some fixed MCS indices support π / 2BPSK transmission. Compared to quadrature phase shift keying (QPSK) transmission, π / 2BPSK transmission may offer a gain at a certain code rate. Different channel conditions, different antenna configurations, different code rate ranges, or different frequency efficiency ranges may all be factors affecting whether π / 2BPSK transmission can achieve a gain compared to QPSK transmission under different MCS indices.

[0004] However, in related technologies, only a portion of the fixed MCS indexes can be configured to support transmission of a certain modulation scheme, resulting in poor flexibility in determining the MCS that supports transmission of a single modulation scheme. Summary of the Invention

[0035] The following explains some concepts and terms involved in the transmission configuration method, apparatus, terminal, network-side equipment and medium provided in the embodiments of this application.

[0036] MCS index table

[0037] In the current protocol, if transform precoding is not enabled, different MCS index tables are selected based on whether the maximum modulation scheme is 64 Quadrature Amplitude Modulation (QAM) or 256 QAM, and whether it is a Low Spectral Efficiency (LowSE) scenario. Examples include Tables 5.1.3.1-1, 5.1.3.1-2, and 5.1.3.1-3 in 3GPP TS 38.214. This applies to both the Physical Downlink Shared Channel (PDSCH) and the Physical Uplink Shared Channel (PUSCH) using Cyclic Prefix (CP)-Orthogonal Frequency Division Multiplexing (OFDM). For PUSCH using Discrete Fourier Transform (DFT)-s-OFDM (which can be transformed precoded), the MCS index tables that can be used are such as Tables 6.1.4.1-1 and 6.1.4.1-2 of 3GPP TS38.214.

[0038] In other words, the PUSCH transmission will determine the modulation mode as π / 2BPSK and the modulation order q = 1 only if the higher-level parameters are configured as tp-pi2BPSK; otherwise, the modulation mode will be determined as QPSK and the modulation order q = 2, or the modulation mode and modulation order will be determined according to the MCS index.

[0039] Maximum Power Reduction (MPR)

[0040] For terminals operating in the n40, n41, n77, n78, and n79 frequency bands, and supporting π / 2 BPSK transmission with power boosting capability (π / 2 BPSK), and with an uplink duty cycle of less than 40% during uplink transmission, the reference power is 26 dBm. This power is applied back off from 26 dBm, with the maximum backoff value listed in Table 6.2.2-1. Otherwise, the reference power is 23 dBm (the maximum transmit power specified by PC3). For example, in the case of external resource block allocation, if π / 2 BPSK transmission is used, the transmit power can reach 26 dBm - 1.2 dB = 24.8 dBm; if QPSK transmission is used, the transmit power can reach 23 dBm - 1 dB = 22 dBm. Therefore, there is a maximum power boosting difference of 2.8 dBm between using π / 2 BPSK transmission and using QPSK transmission. Further enhancements have been made to address the internal resource block allocation scenario. For terminals supporting powerBoosting-pi2BPSK-QPSK-r18 or powerBoosting-pi2BPSK-QPSK-Modified-r18, if the powerBoostingPi2BPSK-r18 function is enabled, the reference power boost is (ΔPPowerBoost - ΔPPowerClass). Similarly, there will be a certain power boosting difference between using π / 2BPSK transmission and using QPSK transmission.

[0041] Power level offset

[0042] For frequency range (FR) 1, the terminal can set a maximum output power configured by the terminal. The protocol specifies an upper and lower limit for the maximum output power configured by the terminal, one factor being the power level offset ΔPPowerClass.

[0043] The transmission configuration method, apparatus, terminal, network-side device, and medium provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0044] The transmission configuration method provided in this application can be applied to scenarios where MCS indexes that support π / 2BPSK transmission are configured.

[0045] For example, the terminal can determine the first MCS based on the first indication information and the second indication information; and the terminal can perform a first transmission based on the first MCS; wherein, the first indication information is used to indicate at least one of the following: the maximum MCS index (e.g., the maximum MCS index that supports π / 2BPSK transmission), the first enable identifier (e.g., an identifier for enabling π / 2BPSK transmission), and the MCS configuration table identifier (e.g., an identifier for indicating the range of MCS indexes or the MCS configuration table that supports π / 2BPSK transmission); the second indication information includes at least one of the first MCS index and the second enable identifier.

[0046] Thus, when determining the MCS, the terminal can base its decision on at least one of the maximum MCS index indicated by the first indication information, the enable flag, and the MCS configuration table flag, as well as the MCS index indicated by the second indication information, without having to configure only a portion of the fixed MCS indexes to support the transmission of a certain modulation scheme, as is the case with related technologies. Therefore, the flexibility in determining the MCS index that supports π / 2BPSK transmission can be improved.

[0047] This application provides a transmission configuration method. Figure 2 A flowchart illustrating a transmission configuration method provided by some embodiments of this application is shown. For example... Figure 2 As shown, some embodiments of this application provide a transmission configuration method that may include the following steps 201 and 202.

[0048] Step 201: The terminal determines the first MCS based on the first indication information and the second indication information.

[0049] The first indication information is used to indicate at least one of the following: the maximum MCS index, the first enable identifier, and the MCS configuration table identifier; the second indication information includes at least one of the first MCS index and the second enable identifier.

[0050] Optionally, in this embodiment of the application, while the terminal determines the first MCS based on the first indication information and the second indication information, it can also determine the configuration information corresponding to the first MCS.

[0051] Optionally, in the embodiments of this application, the above configuration information may include at least one of the following: modulation method, modulation order, code rate, and spectral efficiency.

[0052] Optionally, in the embodiments of this application, the modulation method may include π / 2BPSK, QPSK, 16QAM, 64QAM or 256QAM.

[0053] Optionally, in the embodiments of this application, the modulation order may include any modulation order such as 1, 2, 4, 6 or 8.

[0054] Optionally, in this embodiment, the first MCS index can be determined by higher-layer signaling or physical layer control information; by using the first MCS index as the entry of the MCS configuration table, the modulation method or modulation order, code rate, spectral efficiency, etc. can be determined.

[0055] Optionally, in this embodiment, the second enable flag can be tp-pi2BPSK in the related art.

[0056] Optionally, in the embodiments of this application, the first enable identifier and the second enable identifier are different; for example, the second enable identifier is tp-pi2BPSK, and the first enable identifier is tp-pi2BPSK2 or tp-pi2BPSK3, etc.

[0057] Optionally, in this embodiment of the application, the first indication information may also be used to indicate a de-enable identifier; for example, the de-enable identifier may be a de-enable identifier that supports transmission of the first modulation mode.

[0058] Optionally, in this embodiment of the application, the maximum MCS index is the maximum MCS index that supports the first modulation scheme; and / or, the first enable identifier is an enable identifier that supports transmission of the first modulation scheme; and / or, the MCS configuration table identifier is used to identify the first MCS configuration table, which is an MCS configuration table that includes the first modulation scheme.

[0059] Optionally, in the embodiments of this application, the first modulation method may include π / 2BPSK.

[0060] Optionally, in this embodiment of the application, the above-mentioned MCS configuration table identifier can be used to determine a first MCS configuration table from multiple first MCS configuration tables.

[0061] Optionally, in this embodiment of the application, the above-mentioned MCS configuration table identifier, used to identify the first MCS configuration table, has two meanings:

[0062] 1. The first modulation scheme can be determined using the MCS identifier in the first indication information and the MCS index in the second indication information;

[0063] 2. Use the MCS configuration table identifier in the first instruction information to determine whether it is the first modulation method or the second modulation method. That is, if the indicated MCS configuration table includes the first modulation method, then the first modulation method is used; if the indicated MCS configuration table includes the second modulation method, then the second modulation method is used.

[0064] Optionally, in the embodiments of this application, the above-mentioned maximum MCS index may be included by the first indication information, or indicated by the first information included by the first indication information.

[0065] The first piece of information includes at least one of the following:

[0066] A set consisting of at least one candidate maximum MCS index;

[0067] Supports the MCS range of the first modulation scheme;

[0068] MCS configuration table supporting the first modulation scheme;

[0069] Supports the spectral efficiency of the first modulation scheme;

[0070] Supports the spectral efficiency range of the first modulation scheme;

[0071] The maximum spectral efficiency supported by the first modulation scheme;

[0072] Supports the bit rate of the first modulation scheme;

[0073] Supports the bit rate range of the first modulation scheme;

[0074] Maximum bit rate supported by the first modulation scheme.

[0075] Optionally, in the embodiments of this application, the set of at least one candidate maximum MCS index is a set consisting of one or more candidate maximum MCS indices.

[0076] Optionally, in the embodiments of this application, the set of at least one candidate maximum MCS index can be configured through System Information Block (SIB), Radio Resource Control (RRC) parameters, or protocol predefined methods.

[0077] Optionally, in this embodiment of the application, the first indication information indicating the above-mentioned maximum MCS index can be achieved through the following steps:

[0078] The first step involves configuring a set of first indication information using RRC configuration.

[0079] The second step involves further indicating the set index using methods such as DCI or MAC CE, thereby determining the aforementioned maximum MCS index.

[0080] Optionally, in this embodiment, the maximum MCS index can also be directly indicated by the first indication information in one step. For example, based on the existing MCS configuration table, only one entry needs to be configured or indicated by the first indication information, and the corresponding index is the maximum MCS index. It should be noted that the subsequent indications related to spectral efficiency and code rate follow a similar logic.

[0081] For example, taking π / 2BPSK as the first modulation scheme, the first indication information can directly indicate the MCS index range or MCS configuration table that supports π / 2BPSK transmission, or it can determine the MCS index range that supports π / 2BPSK transmission by indicating the maximum MCS index mentioned above. The terminal determines the configuration information (such as modulation order, modulation scheme, code rate, spectral efficiency, etc.) corresponding to the first MCS index based on the MCS index range that supports π / 2BPSK transmission and in combination with the first MCS index.

[0082] Optionally, in this embodiment, the range of MCS indexes supporting π / 2BPSK transmission is determined based on the first indication information. When the first MCS index is within the range of the MCS indexes, the terminal determines the modulation method as π / 2BPSK and determines the first MCS index in the corresponding MCS table according to the modulation order m = 1. Otherwise, if the first MCS index does not belong to the range of the MCS indexes, the terminal determines the modulation with a modulation order > 1 or the modulation with the default modulation order. The terminal then determines the remaining information (excluding the modulation method and modulation order) in the configuration information corresponding to the first MCS index in the corresponding MCS table according to the first MCS index.

[0083] Optionally, in this embodiment, the MCS index range and / or MCS configuration table supporting π / 2BPSK transmission are determined based on the first indication information. When the first MCS index is within the MCS index range in the MCS configuration table, the terminal determines the modulation method as π / 2BPSK and determines the first MCS index in the MCS configuration table according to the modulation order m=1. Conversely, if the first MCS index is not within the MCS index range in the MCS configuration table, the terminal determines modulation with a modulation order >1 or modulation with the default modulation order. The terminal then determines the remaining information (excluding modulation method and modulation order) in the configuration information corresponding to the first MCS index in the MCS configuration table according to the first MCS index.

[0084] For example, taking π / 2BPSK as the first modulation scheme, the specific example of the indication method of the first indication information is as follows:

[0085] When the indication method of the first indication information includes directly indicating an MCS index as the above-mentioned maximum MCS index, it can directly indicate MCS index#0 or MCS index#4, etc.

[0086] When the indication method of the first indication information includes an MCS configuration table that supports the first modulation method, and the maximum MCS index is determined by combining an entry in the indicated MCS configuration table, the entry can be indicated as 3 or "011" by the RRC parameter, and then the maximum MCS index is determined as MCS index#3 in the corresponding MCS configuration table.

[0087] When the indication method of the first indication information includes a set consisting of at least one maximum MCS index, and the maximum MCS index is determined by the index of the indicated set, a set of maximum MCS indexes can be indicated by the RRC parameter, such as {#0, #2, #6, #10}. Then, an index in the set, such as index 2, is determined by dynamic indication (e.g., DCI, MAC CE). Thus, the maximum MCS index is determined to be the second value in the set, i.e., the maximum MCS index is MCS index #2. The special value #0 corresponds to enabling π / 2BPSK transmission, so the first transmission does not use π / 2BPSK transmission, even if the previous higher-layer parameters configured π / 2BPSK transmission.

[0088] In this embodiment of the application, since the maximum MCS index can be contained in the first indication information or indicated by the first information contained in the first indication information, the maximum MCS index can be determined in different ways, thereby improving the flexibility of determining the maximum MCS index.

[0089] Optionally, in the embodiments of this application, the first indication information may be an indication for a specific MCS range.

[0090] For example, π / 2BPSK transmission can be enabled or disabled independently for different MCS ranges.

[0091] For example, the protocol specifies three MCS ranges: [MCS0, MCS1], [MCS2, MCS4], and [MCS5, MCS6]. Each MCS range has an independent indication of whether to enable or disable π / 2BPSK transmission (using three parameters tp-pi2BPSK, tp-pi2BPSK2, and tp-pi2BPSK3 respectively; their presence indicates that π / 2BPSK modulation is used on the corresponding MCS range).

[0092] Optionally, in the embodiments of this application, step 201 above can be implemented by step 201a or step 201b below.

[0093] Step 201a: When the network is configured or the terminal is enabled to use the first modulation method for transmission, or when the first indication information is provided by the network, the terminal determines the first MCS based on the first indication information and the second indication information.

[0094] Optionally, in this embodiment of the application, the terminal can determine the first MCS based on the size relationship between the first MCS index and the largest MCS index (e.g., the largest MCS index for π / 2BPSK transmission).

[0095] Step 201b: If the terminal does not support transmission using the first modulation method, or the network is not configured or enabled for the terminal to use the first modulation method for transmission, or the first indication information is not provided by the network, the terminal determines the first MCS according to the second indication information.

[0096] Optionally, in this embodiment of the application, when the terminal determines the first MCS according to the second instruction information, the MCS below the maximum MCS index of the protocol predefined mode at least includes QPSK modulation.

[0097] Optionally, in this embodiment of the application, the terminal can determine the first MCS according to the second instruction information in the MCS configuration table. The MCS configuration table is the MCS configuration table configured by the network, such as TS38.214 Table 6.1.4.1-1 or Table 6.1.4.1-2, etc.

[0098] Optionally, in this embodiment of the application, an MCS index in an MCS configuration table corresponds to a set of configuration information, which may include modulation order, code rate and spectral efficiency.

[0099] In this embodiment, when the network configures or enables the terminal to use the first modulation method for transmission, or when the first indication information is provided by the network, the terminal determines the first MCS based on the first indication information and the second indication information; or, when the terminal does not support the use of the first modulation method for transmission, or the network does not configure or enable the terminal to use the first modulation method for transmission, or when the first indication information is not provided by the network, the terminal determines the first MCS according to the second indication information; therefore, different methods can be used to determine the first MCS in different scenarios, thereby improving the flexibility of determining the first MCS.

[0100] Optionally, in the embodiments of this application, step 201 can be implemented by step 201c or step 201d as described below.

[0101] Step 201c: If the first MCS index is less than or equal to the maximum MCS index, the terminal determines the modulation method as the first modulation method and determines the first MCS based on the first MCS configuration table.

[0102] The first MCS configuration table is an MCS configuration table that includes the first modulation scheme.

[0103] For example, if the first MCS index is less than or equal to the maximum MCS index, the terminal can determine the modulation scheme as π / 2BPSK and determine the MCS configuration table in the first MCS configuration table according to the first modulation order. Here, the first modulation order is a modulation order equal to 1.

[0104] Step 201d: If the first MCS index is greater than the maximum MCS index, the terminal determines the first MCS based on the second indication information.

[0105] For example, if the first MCS index is greater than the maximum MCS index, the terminal determines the modulation of the second modulation order and determines the first index in the MCS configuration table. The second modulation order is either a modulation order greater than 1 or the default modulation order.

[0106] In this embodiment, since the terminal can select different methods to determine the configuration information corresponding to the first MCS index based on the size relationship between the first MCS index and the largest MCS index, the flexibility of determining the configuration information corresponding to the first MCS index can be improved.

[0107] Optionally, in this embodiment of the application, the first MCS index being less than or equal to the maximum MCS index may include any of the following:

[0108] The first MCS index is less than or equal to the maximum MCS index mentioned above, and the first MCS index is greater than or equal to 0;

[0109] The first MCS index is less than or equal to the maximum MCS index mentioned above, and the first MCS index is greater than or equal to the second MCS index, wherein the second MCS index is a pre-configured or pre-defined MCS index.

[0110] Optionally, in this embodiment, the second MCS index can be 2 or any possible value.

[0111] It should be noted that the second MCS index is a pre-configured or pre-defined MCS index, taking into account that some small MCS indices in the current protocol already support pi / 2BPSK transmission.

[0112] Optionally, in this embodiment of the application, the first MCS configuration table may contain at least one MCS index.

[0113] Wherein, at least one of the above-mentioned MCS indexes satisfies at least one of the following:

[0114] The index value is less than the index value of the largest MCS index mentioned above;

[0115] The corresponding modulation method is the first modulation method;

[0116] The corresponding modulation order is the first modulation order;

[0117] The corresponding code rate is the first code rate, which is a predefined code rate or determined by a second code rate; wherein, the second code rate is determined by the first MCS index;

[0118] The corresponding spectral efficiency is the first spectral efficiency, which is either a predefined spectral efficiency or determined by the second spectral efficiency; wherein, the second spectral efficiency is determined by the first MCS index.

[0119] Optionally, in the embodiments of this application, at least one MCS index can support π / 2BPSK transmission.

[0120] Optionally, in this embodiment, the number of the at least one MCS index may vary depending on the specific circumstances. For example, in the eMBB scenario, the number of the at least one MCS index is not less than 2, and in the cases of URLLC or lowSE, the number of the at least one MCS index is not less than 6.

[0121] Optionally, in this embodiment, the first modulation order can be 1.

[0122] Optionally, in this embodiment of the application, when the first code rate is determined by the second code rate, the multiple relationship between the first code rate and the second code rate is determined by the ratio of their modulation orders, so as to ensure that the corresponding spectra are equal.

[0123] For example, the first code rate can be twice the code rate corresponding to a modulation order equal to 2, in order to maintain equal spectral efficiency.

[0124] Optionally, in this embodiment of the application, when the first spectral efficiency is determined by the second code rate, the first spectral efficiency and the second spectral efficiency can be equal, that is, the spectral efficiency is guaranteed to remain unchanged.

[0125] For example, the first spectral efficiency can be the spectral efficiency of a modulation order equal to 2.

[0126] For example, the first indication information is used to indicate the maximum MCS index that supports π / 2BPSK transmission. The maximum MCS index is #6. For the MCS table of a traditional terminal, based on the existing PUSCH with transform precoding, its meaning is illustrated in Table 1 below:

[0127] Table 1

[0128]

[0129]

[0130] Furthermore, by using the MCS field in the DCI, the MCS index used to schedule the first transmission is determined to be index#4. At this time, the modulation order used by the first transmission is 1, that is, m=1, the modulation method is π / 2BPSK, and the code rate is (616 / m) / 1024.

[0131] For traditional terminals (or terminals that do not support the mechanism of the first indication information mentioned above), if the MCS index determined by the MCS field in the DCI is index#4, then the modulation order used for transmission is 2, i.e., m=2, the modulation method is QPSK, and the code rate is 308 / 1024.

[0132] For example, the first indication information is used to indicate the maximum MCS index that supports π / 2BPSK transmission. The maximum MCS index is #10. For the LowSE MCS table, based on the existing PUSCH MCS table with transform precoding, the meaning is illustrated in Table 2 below:

[0133] Table 2

[0134]

[0135]

[0136] Optionally, in this embodiment of the application, the first indication information can also be used to indicate the transmission order used in the first transmission, and the modulation scheme corresponding to the transmission order is the first modulation scheme. For example, the above step 201 can be specifically implemented through the following step 201e.

[0137] Step 201e: The terminal determines the first MCS based on the first MCS configuration table.

[0138] The first MCS configuration table is an MCS configuration table that includes the first modulation scheme.

[0139] Optionally, in the embodiments of this application, the first indication information can be predefined by semi-static configuration, dynamic indication, or protocol.

[0140] Optionally, in this embodiment of the application, when the first indication information is configured semi-statically, the first indication information can be configured through SIB or RRC, etc.

[0141] Optionally, in this embodiment of the application, when the first indication information is indicated by dynamic indication, the first indication information can be indicated by downlink control information (DCI) or medium access control (MAC) control element (CE), etc.

[0142] In this embodiment of the application, since the first indication information can be configured semi-statically, dynamically indicated, or predefined by the protocol, the terminal can obtain the first indication information in different ways, thereby improving the flexibility of the terminal in obtaining the first indication information.

[0143] Optionally, in this embodiment of the application, depending on whether the terminal is configured as LowSE or for different MCS configuration tables, the first indication information may satisfy at least one of the following: it is an independent indication, with different values ​​and different value ranges;

[0144] And / or,

[0145] Depending on whether the terminal supports MCS switching, the first indication information can satisfy at least one of the following: it is an independent indication with different values ​​and different value ranges, or the default value indicated by the first indication information can satisfy at least one of the following: it is an independent protocol agreement with different values ​​and different value ranges.

[0146] For example, taking the first indication information as an example, depending on whether the terminal is configured as LowSE or for different MCS configuration tables, it can be indicated independently, with different values ​​or different value ranges. When using a regular MCS configuration table (Enhanced Mobile Broadband (eMBB) scenario), the maximum MCS index supporting π / 2BPSK transmission is greater than #1 (in the existing protocol, MCS#0 and MCS#1 of this MCS configuration table already support π / 2BPSK transmission); when using the MCS configuration table corresponding to LowSE (Ultra-Reliable and Low-Latency Communications (URLLC) scenario), the maximum MCS index supporting π / 2BPSK transmission is greater than #5 (in the existing protocol, MCS#0 to MCS#5 of this MCS configuration table already support π / 2BPSK transmission).

[0147] For example, the first indication information can be independently indicated, with different values ​​or different value ranges depending on whether the terminal supports MCS switching, or the default value indicated by the first indication information can be independently agreed upon by the protocol, with different values ​​or different value ranges depending on whether the terminal supports MCS switching. For terminals that do not support MCS switching, when using the conventional MCS configuration table (eMBB scenario), the maximum MCS index that supports π / 2BPSK transmission is configured as #1 by default; when using the MCS configuration table corresponding to LowSE (URLLC scenario), the maximum MCS index that supports π / 2BPSK transmission is configured as #5 by default.

[0148] Optionally, in this embodiment, the range of values ​​for the maximum MCS index determined or indicated based on the first indication information is also different. For example, in the MCS table (eMBB) used by the normal SE, MCS#0 and MCS#1 already support π / 2BPSK transmission, so the maximum MCS index configured or indicated by the first indication information is greater than #1; in the MCS table (URLLC) used by the LowSE, MCS#0 to MCS#5 already support π / 2BPSK transmission, so the maximum MCS index configured or indicated by the first indication information is greater than #5.

[0149] Optionally, in this embodiment, the value range of the first indication information varies depending on the terminal. For example, for a terminal that does not support MCS switching, when using a conventional MCS table (eMBB scenario), the maximum MCS index is configured to #1 by default; when using the MCS table corresponding to LowSE (URLLC), the maximum MCS index is configured to #5 by default. Alternatively, for a terminal that does not support MCS switching, the terminal does not expect the maximum MCS index configured or indicated by the first indication information to be no greater than 1 or no greater than 5.

[0150] In this embodiment, depending on whether the terminal is configured as LowSE or for different MCS configuration tables, the first indication information can satisfy at least one of the following: it is an independent indication with different values ​​and different value ranges; and / or, depending on whether the terminal supports MCS switching, the first indication information can satisfy at least one of the following: it is an independent indication with different values ​​and different value ranges, or the default value indicated by the first indication information can satisfy at least one of the following: it is an independent protocol agreement with different values ​​and different value ranges; therefore, different first indication information can be configured for different scenarios, thereby improving the flexibility of configuring the first indication information.

[0151] Optionally, in this embodiment of the application, the first indication information is used to indicate the first enable identifier, which is an enable identifier that supports transmission using the first modulation method. Exemplarily, step 201 can be implemented by at least one of steps 201f and 201g described below.

[0152] Step 201f: When the first indication information indicates that the first modulation mode transmission is enabled, the terminal determines the modulation mode as the first modulation mode and determines the first MCS based on the first MCS configuration table.

[0153] The first MCS configuration table is an MCS configuration table that includes the first modulation scheme.

[0154] Step 201g: If the first indication information indicates that the first modulation mode transmission is to be enabled, the terminal determines the first MCS based on the second indication information.

[0155] Optionally, in this embodiment of the application, the first enable flag can be a function switch. When the function switch is turned on, the first modulation method transmission can be supported; when the function switch is turned off, the first modulation method transmission can not be supported.

[0156] For example, when the first indication information indicates that π / 2BPSK transmission is enabled, in the case of LowSE, the first MCS index is #3, then the terminal determines that the modulation order m = 1, the modulation method is π / 2BPSK, and the code rate is (128 / 1) / 1024.

[0157] When the first indication information indicates to enable π / 2BPSK transmission, in the case of LowSE, the first MC index is #3, then the terminal determines the modulation order m = 2, the modulation mode is QPSK, and the code rate is (128 / 2) / 1024.

[0158] When the first indication information configures or indicates that the maximum MCS index is #10, and the first indication information indicates that π / 2BPSK transmission is enabled, in the case of LowSE, the first MCS index is #4, then the terminal determines that the modulation order m = 1, the modulation mode is π / 2BPSK, and the code rate is (616 / 1) / 1024.

[0159] When the first indication information configures or indicates that the maximum MCS index is #10, and the first indication information indicates that π / 2BPSK transmission is disabled, in the case of LowSE, the first MCS index is #4, then the terminal determines that the modulation order m = 2, the modulation mode is QPSK, and the code rate is (616 / 2) / 1024.

[0160] In this embodiment of the application, since the first modulation mode can be enabled or disabled according to the first indication information, and the first MCS can be determined in different ways, the flexibility of determining the first MCS can be improved.

[0161] Optionally, in the embodiments of this application, the first enable flag can be used to toggle the enable or disable state of the most recent transmission using the first modulation method, or to directly enable or disable transmission using the first modulation method.

[0162] It is understood that when the aforementioned first enable flag is used to toggle the enable or disable state of the most recent transmission using the first modulation method, the first modulation method can be enabled or disabled for transmission by switching the enable or disable state. When the aforementioned first enable flag is used to directly enable or disable the first modulation method for transmission, the first modulation method can be enabled or disabled for transmission directly without switching the enable or disable state. In this embodiment of the application, since the aforementioned first enable flag can be used to toggle the enable or disable state of the most recent transmission using the first modulation method, or to directly enable or disable the first modulation method for transmission, the first indication information can be configured in different ways, thereby improving the flexibility of configuring the first indication information.

[0163] Optionally, in this embodiment of the application, the first indication information can be indicated by at least one of the following: the MCS index indicated by the MCS field in the downlink control information, the reserved code points in the MCS field, the field dedicated to enabling or disabling transmission using the first modulation method, and the New Data Indication (NDI) field.

[0164] For example, taking π / 2BPSK as the first modulation scheme, when the first indication information is indicated by the aforementioned NDI, if the initial transmission uses π / 2BPSK, then the retransmission will default to disabling π / 2BPSK transmission; or, if the initial transmission disables π / 2BPSK transmission, then the retransmission will enable π / 2BPSK transmission. For instance, if the MCS index is lower than the maximum MCS index supporting π / 2BPSK transmission during the initial transmission, but π / 2BPSK transmission is not enabled, then the retransmission will default to enabling π / 2BPSK transmission.

[0165] When the first indication information is indicated by the MCS index indicated by the above MCS field, if the MCS index indicated during the initial transmission is higher than the maximum MCS index that supports π / 2BPSK transmission, then π / 2BPSK transmission is not enabled; if the new MCS index indicated during the retransmission is lower than the maximum MCS index that supports π / 2BPSK transmission, then π / 2BPSK transmission is enabled during the retransmission.

[0166] When the first indication information is indicated by the code point reserved in the above MCS field, the initial MCS index is maintained or used, but the π / 2BPSK transmission is toggled to enable or disable.

[0167] Optionally, in the embodiments of this application, the domain dedicated to enabling or disabling transmission using the first modulation method can be a newly added domain.

[0168] Optionally, in this embodiment, whether retransmission is enabled to use the first modulation scheme depends on the initial transmission. For example, if the MCS indexes configured for both the initial transmission and retransmission support π / 2BPSK, then either π / 2BPSK transmission is enabled for both, or π / 2BPSK transmission is disabled for both.

[0169] In this embodiment of the application, since the first indication information can be indicated by at least one of the following: the MCS index indicated by the MCS field in the downlink control information, the code point reserved in the MCS field, the field dedicated to enabling or disabling transmission using the first modulation method, and the NDI field, different methods can be used to indicate the first indication information, thereby improving the flexibility of indicating the first indication information.

[0170] Step 202: The terminal performs the first transmission based on the first MCS.

[0171] Optionally, in the embodiments of this application, the first transmission can be a transmission without frequency hopping, wherein the frequency hopping is at least one of inter-slot frequency hopping, intra-slot frequency hopping, and first time block frequency hopping.

[0172] Optionally, in the embodiments of this application, the first time block in the first time block frequency hopping mainly refers to the frequency hopping granularity in the time dimension, taking a certain length of transmission resources as a hop. For example, one or more time slots are bundled together as a hop, or 1ms or several ms of transmission are bundled together as a hop; in the Dedicated demodulation reference signals (DMRS) bundling mechanism, a frequency hopping interval is specifically configured for the time-domain granularity of frequency hopping under the DMRS bundling mechanism; another potential example is when PUSCH enables Orthogonal Covering Codes (OCC) transmission, frequency hopping is performed at the granularity of an OCC group.

[0173] For example, when in-slot frequency hopping is enabled, π / 2BPSK is not supported, or π / 2BPSK is not supported within a specific MCS index range.

[0174] In this embodiment of the application, since the first transmission can be a transmission without frequency hopping, the resource block configuration caused by frequency hopping can be avoided from not conforming to the division of internal or external resource blocks.

[0175] Optionally, in this embodiment, the cell where the terminal is located is a carrier aggregation deployment or a dual-connectivity deployment. For example, the component carrier (CC) of the first transmission can satisfy at least one of the following:

[0176] In the case of multiple CCs in a frequency band, a single CC is used to support power enhancement;

[0177] In cases where all frequency bands for carrier aggregation or dual connectivity deployment have only a single CC, a single CC on the frequency band supporting power enhancement is required.

[0178] If the frequency band for deploying carrier aggregation or dual connectivity is a combination of FR1 and FR2, and all frequency bands for deploying carrier aggregation or dual connectivity have only a single CC, then it is a single CC on FR1.

[0179] It can be understood that the aforementioned frequency band is a frequency band for deploying carrier aggregation or dual connectivity.

[0180] In this embodiment of the application, since the CC where the terminal is located can satisfy at least one of the above requirements when the cell is deployed by carrier aggregation or dual connectivity, the flexibility of configuring the CC where the first transmission is located can be improved when the cell is deployed by carrier aggregation or dual connectivity.

[0181] Optionally, in the embodiments of this application, when the first transmission is an uplink transmission, it includes at least one of the following:

[0182] The Physical downlink control channel (PUCCH) and its repetition;

[0183] PUSCH, its repetition, Transmission Block Over Multiple Slots (TBoMS) PUSCH, Configured Grant (CG) PUSCH, DG PUSCH, etc.

[0184] A message (Msg) is a PUSCH, a Msg3 PUSCH, or a Msg5 PUSCH, and its repetition.

[0185] Optionally, in this embodiment of the application, when the first transmission is a different channel, such as PUCCH or PUSCH, the first indication information is an independent configuration or indication.

[0186] Optionally, in this embodiment of the application, when the first transmission is CG PUSCH, the first indication information can be dynamically indicated through MACCE.

[0187] Optionally, in the embodiments of this application, when the first transmission is a downlink transmission, it includes: PDSCH with DFT-s-OFDM and its repetition.

[0188] Optionally, in this embodiment of the application, if the terminal's power level is a first preset power level or the power level change (Delta Power Class, DPC) reported by the terminal meets the first condition, the terminal may satisfy at least one of the following:

[0189] First transmission is not supported;

[0190] The maximum supported MCS index is no greater than the third MCS index.

[0191] Transmission using the first modulation scheme is not supported.

[0192] Transmission of the first modulation scheme within a specific MCS index range is not supported.

[0193] The first modulation method is supported only at the second preset power level;

[0194] Transmission using the first modulation method is supported only if the maximum transmit power obtained after adding the above DPC at the second preset power level does not exceed the preset value;

[0195] The first condition includes at least one of the following: the DPC is a predetermined value, the DPC is greater than or equal to a first threshold, and the DPC is less than or equal to a second threshold.

[0196] Optionally, in this embodiment of the application, the modulation method used for the first transmission is a first modulation method.

[0197] Optionally, in this embodiment of the application, the first threshold and the second threshold can be any threshold agreed upon by the protocol or configured by the network.

[0198] Optionally, in the embodiments of this application, the first preset power level can be power level 2 or power level 1.5, etc.

[0199] Optionally, in this embodiment of the application, the first transmission is not supported, that is, the first transmission based on the first indication information determines the first configuration.

[0200] Optionally, in the embodiments of this application, the maximum supported MCS index is not greater than the third MCS index, which can be understood as: it is not expected that the maximum supported MCS index is greater than the third MCS index.

[0201] Optionally, in this embodiment of the application, the third MCS index can be #1 (MCS configuration table for normal spectral efficiency) or #5 (MCS configuration table for low spectral efficiency).

[0202] For example, taking the case where the terminal does not support π / 2BPSK transmission, when the terminal power level capability received by the network is PC2 or PC1.5, π / 2BPSK transmission is not supported; when the terminal power level capability received by the network is PC3, but the reported DPC is positive (e.g., 3dB) or exceeds a certain value, π / 2BPSK transmission is not supported; when the terminal power level capability received by the network is PC3, but the reported DPC is positive (e.g., 3dB) or exceeds a certain value, π / 2BPSK transmission is not supported for the first transmission after a certain period of time following the DPC reporting, where the certain period of time can be specified by the protocol or configured by the network.

[0203] For example, taking the case where the terminal does not support π / 2BPSK transmission within a specific MCS index range, when the network receives the terminal power level capability as PC2 or PC1.5, π / 2BPSK transmission within that specific MCS index range is not supported; when the network receives the terminal power level capability as PC3, but the reported DPC is positive (e.g., 3dB) or exceeds a certain value, π / 2BPSK transmission within that specific MCS index range is not supported; when the network receives the terminal power level capability as PC3, but the reported DPC is positive (e.g., 3dB) or exceeds a certain value, for the first transmission after a certain period of time following DPC reporting, π / 2BPSK transmission within that specific MCS index range is not supported, where the certain period of time can be specified by the protocol or configured by the network.

[0204] Optionally, in this embodiment, the second preset power level can be PC3.

[0205] Optionally, in this embodiment of the application, the reporting time of the DPC may be earlier than the start time of the first transmission, and the interval between the reporting time of the DPC and the start time of the first transmission is greater than or equal to the first time threshold.

[0206] Optionally, in this embodiment of the application, the first time threshold may be agreed upon by a protocol or configured by the network.

[0207] In this embodiment of the application, since the terminal can satisfy at least one of the above conditions when the terminal's power level is the first preset power level or the DPC reported by the terminal meets the first condition, the terminal in different scenarios can determine the configuration information corresponding to the first MCS index based on the first indication information, thereby further improving the flexibility of configuring the MCS index that supports the transmission of the first modulation method.

[0208] In the transmission configuration method provided in the embodiments of this application, since the terminal can determine the MCS based on at least one of the maximum MCS index indicated by the first indication information, the first enable identifier, and the MCS configuration table identifier, as well as at least one of the MCS index indicated by the second indication information and the second enable identifier, instead of configuring only a partially fixed MCS index to support the transmission of a certain modulation mode as in related technologies, the flexibility of determining the MCS index that supports the transmission of a modulation mode can be improved.

[0209] Optionally, the transmission configuration method provided in this application embodiment may further include the following step 203.

[0210] Step 203: The terminal reports the second information.

[0211] The second information is at least one of terminal capability information and auxiliary information, and the second information includes at least one of the following:

[0212] Power levels supported by the terminal;

[0213] The maximum power back-off value supported by the terminal at different modulation orders under the corresponding power level;

[0214] The power boost value supported by the terminal between different power levels;

[0215] Indicates whether the terminal supports information transmitted using the first modulation scheme;

[0216] Indicates whether the terminal supports information transmitted using the first modulation scheme with an MCS index greater than or not less than the third threshold;

[0217] Indicates whether the terminal supports information transmitted using the first modulation scheme with an MCS index that is less than or no greater than the fourth threshold;

[0218] Information indicating whether the terminal supports power enhancement for transmission using the first modulation method;

[0219] Information indicating whether the terminal supports switching between the second modulation mode transmission and the first modulation mode transmission;

[0220] The maximum MCS index that the terminal supports for transmission using the first modulation scheme;

[0221] The terminal supports frequency bands for transmission using the first modulation method;

[0222] Does the terminal support dynamically enabling or disabling the frequency band for transmission using the first modulation method?

[0223] The performance gap between the second modulation mode transmission and the first modulation mode transmission under the same MCS index;

[0224] The gap between the second modulation mode transmission and the first modulation mode transmission under the same MCS index of the terminal, the first indicator includes at least one of reference signal received power, reference signal received quality and received signal strength indication;

[0225] The modulation order or modulation scheme that the terminal expects to use;

[0226] The terminal expects the first modulation scheme to support the maximum spectral efficiency.

[0227] In this embodiment of the application, since the terminal can report at least one of the terminal capability information and auxiliary information, the network can learn at least one of the capability information and auxiliary information related to the first modulation mode transmission supported or desired by the terminal, thereby facilitating the network to accurately configure the relevant information of the first modulation mode transmission.

[0228] Optionally, in this embodiment of the application, the reporting granularity of the second information can satisfy at least one of the following:

[0229] Specific or different MCS index ranges;

[0230] Specific or different MCS index tables;

[0231] Each terminal;

[0232] Each frequency band;

[0233] Each frequency band combination;

[0234] Each carrier or each group of carriers;

[0235] Each Transmission Reception Point (TRP) or each TRP group;

[0236] Each sub-band;

[0237] Each Synchronization Signal Block (SSB) or each group of SSBs.

[0238] In this embodiment of the application, since the reporting granularity of the second information can satisfy at least one of the above, the terminal can use different reporting granularities to report the second information, thereby improving the flexibility of reporting the second information.

[0239] This application provides a transmission configuration method. Figure 3 A flowchart illustrating a transmission configuration method provided by some embodiments of this application is shown. For example... Figure 3 As shown, some embodiments of this application provide a transmission configuration method that may include the following step 301.

[0240] Step 301: The network-side device sends the first instruction information and the second instruction information to the terminal.

[0241] The first indication information is used to indicate at least one of the following: the maximum MCS index, the first enable identifier, and the MCS configuration table identifier; the second indication information includes at least one of the first MCS index and the second enable identifier.

[0242] In the transmission configuration method provided in some embodiments of this application, since the network-side device can send first indication information and second indication information to the terminal, the terminal can determine the MCS index based on at least one of the maximum MCS index indicated by the first indication information, the first enable identifier, and the MCS configuration table identifier, as well as at least one of the MCS index indicated by the second indication information and the second enable identifier, without having to configure only a partially fixed MCS index to support the transmission of a certain modulation scheme, as is the case in related technologies. Therefore, the flexibility in determining the MCS index that supports the transmission of a certain modulation scheme can be improved.

[0243] Optionally, some embodiments of this application may further include the following step 302 in the transmission configuration method.

[0248] The power boost value supported by the terminal between different power levels;

[0249] Indicates whether the terminal supports information transmitted using the first modulation scheme;

[0250] Indicates whether the terminal supports information transmitted using the first modulation scheme with an MCS index greater than or not less than the third threshold;
