Description

Technical Field

[0001] This disclosure relates generally to wireless communications, including but not limited to systems and methods for indicating transmission schemes. Background Technology

[0002] The standards organization Third Generation Partnership Project (3GPP) is currently developing a new radio interface called 5G New Radio (5G NR) and the Next Generation Packet Core Network (NG-CN or NGC). 5G NR will consist of three main components: the 5G Access Network (5G-AN), the 5G Core Network (5GC), and User Equipment (UE). To facilitate the implementation of different data services and needs, the elements of the 5GC (also known as Network Functions) have been simplified so that some are software-based and some are hardware-based, allowing these elements to be adapted as needed. Summary of the Invention

[0003] The exemplary embodiments disclosed herein relate to solving one or more problems presented in the prior art, and provide additional features that will readily become apparent from the following detailed description taken in conjunction with the accompanying drawings. According to various embodiments, exemplary systems, methods, apparatuses, and computer program products are disclosed herein. However, it should be understood that these embodiments are presented by way of example and are not restrictive, and that various modifications can be made to the disclosed embodiments while remaining within the scope of this disclosure, as will be apparent to those skilled in the art who have read this disclosure.

[0004] At least one aspect relates to a system, method, apparatus, or computer-readable medium that includes the following: A wireless communication device (e.g., a UE) can receive / acquire / obtain a first indication of multiple modulation and coding schemes (MCS) for multiple transmissions of at least one transmission block (TB) from a wireless communication node (e.g., a base station (BS), gNB, transmission and reception point (TRP), or satellite). The wireless communication device can determine the multiple modulation and coding schemes (MCS) for the multiple transmissions of at least one TB based on the first indication.

[0005] In some implementations, the first indication may include multiple bit fields to indicate multiple modulation and coding scheme (MCS) indices corresponding to multiple transmissions. In some implementations, the second indication may be indicated by higher-layer signaling, which includes at least one of the following: reusing or redefining the first field for indicating the configuration of time domain resource allocation (TDRA) corresponding to multiple start and length indicators (SLIVs) of multiple transmissions; and / or defining the second field for indicating the configuration of time domain resource allocation (TDRA) corresponding to multiple start and length indicators (SLIVs) of multiple transmissions.

[0006] In some implementations, the wireless communication device may receive a second indication from a wireless communication node. The wireless communication device may use the second indication and a Time Domain Resource Allocation (TDRA) table to determine multiple start and length indicators (SLIVs) for multiple transmissions of at least one transport block (TB), and / or, when a condition is met, the wireless communication device may use the second indication and the TDRA table to determine multiple start and length indicators (SLIVs) for multiple transmissions of at least one transport block (TB); wherein the condition may include a flag field configured via higher-layer signaling, which indicates that the first field is reused or redefined to indicate the configuration of the Time Domain Resource Allocation (TDRA).

[0007] In some implementations, the wireless communication device can receive downlink control information (DCI) signaling from a wireless communication node, which includes a third indication. This third indication can be at least one of the following: used to indicate multiple transmissions ( I The number of ), which corresponds to the number in multiple start and length indicators SLIV, and / or has been determined as The bit width.

[0008] In some implementations, the first indication may indicate at least one of the following: the multiple transmissions will use the same MCS; the multiple transmissions will use different MCS; and / or the multiple transmissions will use different modulation orders while using the same coding rate. In some implementations, the second indication corresponding to the first indication of the multiple transmissions may indicate at least one of the following: slot offset (K0), the start symbol in a slot, the transmission mapping type, the position of the demodulation reference signal (DMRS) corresponding to at least one of the multiple transmissions, and / or the assigned symbol length.

[0009] In some implementations, at least one of the following is true: the first allocated symbol length (x1) corresponds to a time slot of the first transmission in a plurality of transmissions using the first modulation order, and the second allocated symbol length (x2) corresponds to two consecutive time slots bundled together for the second transmission in a plurality of transmissions using the second modulation order, where x1 equals x2, and the number of consecutive time slots is associated with log2((the first modulation order indicated by the MCS of the first transmission) / (the second modulation order indicated by the MCS of the second transmission)); and / or the first allocated symbol length (x1) corresponds to a time slot of the first transmission using the first modulation order, and the second allocated symbol length (x2) corresponds to a time slot of the second transmission using the second modulation order, where x2 equals x1 multiplied by log2((the first modulation order indicated by the MCS of the first transmission) / (the second modulation order indicated by the MCS of the second transmission)).

[0010] In some implementations, if a second indication is configured, the wireless communication device can receive a fourth indication of multiple New Data Indicators (NDIs) from multiple transmissions from the wireless communication node. In this case, the fourth indication may have a bit width determined based on the maximum number of schedulable transmissions among all entries in the second indication.

[0011] In some implementations, if a second indicator is configured, the wireless communication device receives a fifth indicator representing multiple redundant versions (RVs) of multiple transmissions from the wireless communication node. In this case, the bit width of the fifth indicator can be determined based on the maximum number of schedulable transmissions across all entries in the second indicator. In some implementations, the bit width of the first indicator can be 5. I ,in I This corresponds to the number in multiple SLIVs.

Specifically, the systems and methods discussed in this paper address a new solution for supporting transmission schemes that indicate at least one corresponding modulation and coding scheme (MCS) for multiple transmissions of the same transport block (TB) or different TBs. The systems and methods can support a transmission scheme for merging and / or decoding multiple transmissions of the same TB with different MCSs. The systems and methods can support other types of transmission schemes, not just those discussed in this paper. Attached Figure Description

System 200 may include components and elements configured to support known or conventional operating characteristics that do not need to be described in detail herein. In one illustrative embodiment, system 200 may be used in wireless communication environments (such as those described above) Figure 1In a wireless communication environment 100, communication (e.g., sending and receiving) data symbols.

[0019] The system 200 typically includes a base station 202 (hereinafter referred to as "BS 202") and a user equipment 204 (hereinafter referred to as "UE 204").

Each module is coupled to and interconnected with each other as needed via a data communication bus 240. BS 202 communicates with UE 204 via communication channel 250 (hereinafter also referred to as wireless transmission link 250, wireless data communication link 250), which can be any wireless channel or other medium suitable for the data transmission described herein.

The operation of the two transceiver modules 210 and 230 may be time-coordinated such that while the downlink transmitter is coupled to downlink antenna 212, the uplink receiver circuitry is coupled to uplink antenna 232 to receive transmissions via wireless transmission link 250. Conversely, the operation of the two transceivers 210 and 230 can be coordinated in time, such that while the uplink transmitter is coupled to the uplink antenna 232, the downlink receiver is coupled to the downlink antenna 212 to receive transmissions via the wireless transmission link 250. In some embodiments, there is tight time synchronization with a minimum guard time between changes in the duplex direction.

[0028] 2. Systems and methods for indicating transmission schemes In some communication systems, satellites with relatively limited transmit power and / or processing bandwidth (e.g., satellites with relatively low performance or functionality) can serve a portion of a potential satellite coverage area at a given time, based on or given a specific signal-to-noise ratio (SNR) of the physical channels supported by a New Radio (NR) Non-Terrestrial Network (NTN) (e.g., at the UE level). In some systems, satellites can be configured to optimize power deployment or settings, potentially reducing / lowering or limiting network coverage. In such systems, downlink (DL) coverage enhancement techniques may need to be implemented to optimize, for example, network infrastructure and / or operational resources, to achieve predefined target coverage. Therefore, the systems and methods of the technical solutions discussed herein can provide transmission scheme indications for enhancing coverage, including but not limited to enhancing the coverage of non-terrestrial networks (NTNs).

DCI format 0_1 ​​can be used to schedule one or more Physical Uplink Shared Channels (PUSCH) within a cell. If the higher-layer parameter pdsch time-domain allocation list DCI-0-1 is configured ( pusch-TimeDomainAllocationListDCI-0-1 ) and / or the pdsch time-domain assignment list of the higher-level parameter MultiPDSCH ( pdsch-TimeDomainAllocationListForMultiPDSCH According to this specification, time-domain resource allocation can occupy, but is not limited to, at least one of 0, 1, 2, 3, 4, 5, and / or 6 bits.

[0035] Given the relatively large / wide gap in meeting the required link resources (e.g., budget), the systems and methods of the technical solutions can provide a (e.g., a new) transmission scheme to indicate at least one corresponding modulation and coding scheme (MCS) for the transmission of one or more transport blocks (TBs). By providing or configuring the transmission scheme, the systems and methods can allow at the receiving end (e.g., UE 104) to combine and / or decode multiple transmissions with different MCSs of the same transport block (TB).

[0036] Example implementation: Enhanced transmission scheme In various configurations, systems and methods can consider or implement various methods, techniques, or features to improve the coverage performance of new transmission schemes, and are not limited to those discussed herein. In some implementations, existing signaling can be reused / repurposed / redefined for the transmission scheme, and / or a new field can be defined / configured / indicated as the time-domain allocation for MultiTrans. timeDomainAllocationforMultiTrans Indicators (e.g., second indicators). The configuration of new fields for existing signaling and / or second indicators can be included as part of Example Method 1. MultiTrans time-domain allocation ( timeDomainAllocationforMultiTrans Indicators (e.g., reused signaling or new fields) can be configured or indicated by higher-level signaling to indicate the time-domain configuration for multiple transmissions. MultiTrans's time-domain allocation ( timeDomai nAllocationforMultiTrans The indicator can indicate the configuration of time domain resource allocation (TDRA), which can correspond to one or more lines containing start and length indicator values ​​(SLIV) for multiple transmissions.

[0037] The existing signaling can be referred to as the first field, which will be reused / redefined to indicate the TDRA configuration corresponding to multiple SLIVs for multiple data transmissions. The new field can be referred to as the second field, which is used to indicate the time-domain resource allocation (TDRA) configuration corresponding to multiple SLIVs for multiple transmissions. In some configurations, a flag field can be configured via higher-layer signaling to indicate whether at least one existing signaling is reused / redefined / reused as the time-domain allocation for MultiTrans. timeDomainAllocationforMultiTrans In some cases, if a flag field is configured, existing signaling can be reused for MultiTrans time-domain assignments. timeDomainAllocationforM ultiTrans The indicator indicates the configuration of one or more rows corresponding to a TDRA containing multiple SLIVs for multiple transmissions.

[0038] For example, base station BS 102 (e.g., gNB, TRP, or access network equipment) and / or satellite may send / transmit / provide / communicate / issue a second indication to UE 104, which includes at least one of a first field and / or a second field. UE 104 may receive / acquire / obtain the second indication from base station BS 102. UE 104 may use the second indication and a TDRA table to determine multiple SLIVs for various data transmissions of at least one transport block TB. In some cases, UE 104 may perform the determination of multiple SLIVs for multiple transmissions when at least one condition is met. In this case, the condition may include a flag field configured by higher-layer signaling to indicate that the first field is reused / redefined to indicate the TDRA configuration. In some cases, the condition may include a second indication configured by higher-layer signaling to indicate the configuration of one or more rows of TDRA corresponding to multiple SLIVs for multiple transmissions.

[0039] Example Case 1: The new field is defined as the time domain allocation indicator for MultiTrans (timeDomainAllocati onforMultiTrans Indicator) In some implementations, if a new field is defined as the time-domain allocation of MultiTrans ( timeDoma inAllocationforMultiTrans The indicator, which indicates the configuration of the Time Domain Resource Allocation (TDRA) table (corresponding to one or more rows of multiple start and length indicators SLIV containing multiple transmissions), can define at least one of the following fields (but is not limited to).

[0040] For example, a new time-domain resource allocation (e.g., a field) can be defined / indicated / configured to indicate the number of scheduled transmissions issued in DCI signaling (or other types of signaling), as described or mentioned, for example, as part of Example Method 2. The number of scheduled transmissions can be related to the time-domain allocation of MultiTrans ( timeDomainAllocationforMultiTrans The number of SLIVs indicated in the line corresponds to this. If the time-domain allocation of the higher-level parameter MultiTrans is configured ( timeDomain AllocationforMultiTrans Then, the bit width of this field (e.g., time-domain resource allocation) can be determined to be [log2( I )] bits, where I This can represent the time-domain allocation of the higher-level parameter MultiTrans. timeDomainAllocationforMultiT rans The number of entries or scheduled transfers in the data (e.g., the number of SLIVs). If the time-domain allocation of the higher-level parameter MultiTrans is not configured ( timeDomainAllocationforMultiTransIf so, the bit width of this field can be configured according to the specification. In some implementations, the new temporal resource allocation can be referred to as a third indicator, which can indicate the number of transmissions corresponding to the number of SLIVs (e.g., I ), and / or have a value determined as [log2( I The bit width.

[0041] In another example, a new MCS indicator (e.g., a first indicator) can be defined to indicate a set of MCS indices corresponding to one or more TBs of multiple transmissions, as described or mentioned, for example, as part of Example Method 3. In this case, if the time-domain allocation of the higher-level parameter MultiTrans is configured ( timeDomainAllocationforMulti Trans Then, it can be determined that the bit width of this field (e.g., the Modulation Coding Scheme (MCS) indicator or the first indicator) is 5. I Bit OR equals 5 I bits, of which I This can represent or correspond to the time-domain allocation of the higher-level parameter MultiTrans. timeDomain AllocationforMultiTrans The number of entries or transmissions in the (e.g., the number of start and length indicators SLIVs). Each group of 5 bits can correspond to the modulation and coding scheme MCS index / index of a single transmission for multiple transmissions of at least one transport block TB. If the time-domain allocation of the higher-level parameter MultiTrans is not configured ( timeDomainAllocatio nforMultiTrans If the field width follows the specification or is configured according to the specification, then the field width is not specified.

[0042] In some implementations, the MCS indicator (e.g., indicated by the MCS indicator or the first indicator) that includes the modulation order and coding rate (code rate) of multiple transmissions can be configured to indicate at least one of the following (but is not limited to): • The MCS indicator may include at least one modulation order and coding rate, which may be the same as the modulation order and coding rate of the first transmission in a series of transmissions. In this case, the same modulation order and coding rate can be used for multiple transmissions.

[0043] • The MCS indicator may include at least one modulation order and coding rate, which may differ for multiple transmissions. In this case, one or more transmissions in a series of transmissions may use different modulation orders and coding rates.

[0044] • For multiple transmissions, the modulation order can differ from the first transmission, but the coding rate can remain the same. In this case, for example, multiple transmissions can use different modulation orders while maintaining the same coding rate. Various combinations of the same or different modulation orders and / or the same coding rate can be considered for multiple transmissions. For example, the MCS for two transmissions of a TB could include MCS index 6 and MCS index 4, corresponding to (16-QAM, coding rate 1 (CR1)) and (QPSK, CR1) respectively. Simultaneously, the time-domain allocation of MultiTrans in SLIV (…) timeDomainAllocationforMultiTrans The corresponding resources configured for two transmissions of a TB may include, but are not limited to: the allocation symbol length x1 may correspond to one time slot (e.g., consecutive time slots) of the first transmission of a TB, whose modulation may be 16QAM; the allocation symbol length x2 may correspond to two consecutive time slots bound together in the second transmission of the same TB, whose modulation may be QPSK, where x1 equals x2, and the number of consecutive time slots in subsequent transmissions may be equal to... (Or calculated according to the formula) associated; or the allocated symbol length x1 can correspond to a time slot (e.g., consecutive time slots) of the first transmission of 1TB, whose modulation can be 16QAM; the allocated symbol length x2 can correspond to a time slot (e.g., consecutive time slots) of the second transmission of the same TB, whose modulation can be QPSK, where x2 is equal to x1 multiplied by In this example, by changing the length of the assigned symbol, SLIV can ensure multiple transmissions with different modulations and the same coding rate, transmitted / sent / provided through the same frequency domain resources.

[0045] In some respects, for new data indicators (e.g., the fourth indicator), for example, part of example method 4, if the time-domain allocation of the high-level parameter MultiTrans is configured ( timeDomainAllocationforMultiTrans (For example, the second indicator), can be assigned according to or based on the time domain of the higher-level parameter MultiTrans ( timeDomainAlloca tionforMultiTra The maximum number of schedulable transmissions in (e.g., all or more valid) entries in ns) determines at least one of 2, 3, 4, 5, 6, 7, and / or 8 bits (e.g., bit width). A New Data Indicator (NDI) can be included as part of a fourth indicator, which may include one or more New Data Indicators (NDIs) for multiple data transmissions. Each bit can correspond to one scheduled transmission. If the time-domain allocation of the higher-level parameter MultiTrans is not configured ( tim eDomainAllocationforMultiTrans Then, the number of bits for the bit width can be determined according to the specification.

[0046] For redundant versions, such as part of example method 5, if the time-domain allocation of the higher-level parameter MultiTrans is configured ( timeDomainAllocationforMultiTrans (For example, the second indication), can be allocated according to the time domain of the higher-level parameter MultiTrans ( timeDomainAllocationforMultiTrans The maximum number of schedulable transmissions in (e.g., all or more valid) entries in the table determines at least one bit width of 2, 3, 4, 5, 6, 7, and / or 8 bits, but is not limited to this. Each bit can correspond to one scheduled transmission, and a redundant version can be determined according to Example Table 1, but is not limited to this. If the time-domain allocation of the higher-level parameter MultiTrans is not configured ( timeDomainAllocationforMultiTrans The bit width can then be determined according to the specification. For example, if a second indicator is configured (e.g., the time-domain allocation of the higher-level parameter MultiTrans), the bit width can be determined accordingly. t imeDomainAllocationforMultiTrans If the second instruction is received, then UE 104 may receive a fifth indication from BS 102, indicating one or more Redundancy Versions (RVs) for multiple transmissions. This fifth indication may include a bit width determined based on the maximum number of schedulable transmissions among all entries in the second indication.

[0047] In some implementations, as part of example method 6, if UE 104 is configured with MultiTrans time-domain allocation ( timeDomainAllocationforMultiTrans (For example, the second instruction), where one or more lines include / contain multiple SLIVs of at least one TB, then UE 104 cannot configure the pdsch-time domain allocation list of the higher-level parameter MultiPDSCH-r17 ( pdsch-TimeDomainAllocationListForMultiPDSCH-r17 In some cases, as part of example method 7, if UE 104 is configured with MultiTrans time-domain allocation ( timeDomainAllocationforMu ltiTrans If one or more lines contain multiple SLIVs of at least one TB, then UE 104 may not include the PDSCH aggregation factor in the PDSCH configuration (PDSCH-config) (e.g., the PDSCH configuration). pdsch-AggregationFactor This applies to DCI signaling (or other types of signaling) (if configured).

[0048] In some arrangements, as part of example method 8, if UE 104 is configured with MultiTrans time-domain allocation ( timeDomainAllocationforMultiTrans), wherein one or more lines contain multiple SLIVs of at least one TB, and when any two DCIs end with the same symbol and at least one DCI schedules multiple TBs, UE 104 may determine, anticipate or assume that the TBs scheduled by the two DCIs do not have overlapping spans, wherein the span associated with the DCI is defined from the beginning of the first scheduled TB and / or to the end of the last scheduled TB.

[0049] For the time domain allocation of MultiTrans in higher-level signaling ( timeDomainAllocationforMultiTra ns As part of Example Method 9, each TB can have a separate SLIV, mapping type, and / or slot offset (K0), etc. The number of TBs scheduled can be determined by or according to the DCI format, such as, but not limited to, DCI format 1_1, the time-domain allocation of MultiTrans ( timeDomainAllocationforMultiTrans The number of SLIVs indicated in the line is used to indicate / send.

[0050] In some arrangements, as part of example method 10, if UE 104 is configured with MultiTrans time-domain allocation ( timeDomainAllocationforMultiTrans If one or more lines include multiple SLIVs for a TB, and DCI signaling (e.g., DCI format 1_1 or other formats) instructs UE 104 to retransmit at least one TB corresponding to a semi-persistent scheduling (SPS), then UE 104 can determine the time-domain allocation of the MultiTrans indicated by the DCI signaling. timeDomainAllocationforMultiTrans The number of SLIVs in the line is 1 or less. In other words, UE 104 may not expect DCI signaling to be allocated in the time domain of MultiTrans ( timeDomainAllocationforMult iTrans The number of SLIVs indicated in the time-domain allocation line exceeds 1.

[0051] In some respects, as part of example method 11, when UE 104 is configured with the time-domain allocation of MultiTrans ( timeDomainAllocationforMultiTrans When triggered, the aperiodic zero-power (ZP) channel state information reference signal (CSI-RS) can be applied to one or more time slots of all scheduled (one or more) TBs and / or TBs activated / enabled by DCI signaling that includes / contains the triggered signaling. In some implementations, as part of example method 12, if UE 104 is configured with MultiTrans time domain allocation ( timeDomainAllocationforMultiTransIf one or more lines include multiple SLIVs of the TB on the downlink (DL) bandwidth part (BWP) of the serving cell, and UE 104 receives DCI signaling carrying a TCI-State indication but without assignment, then UE 104 may not expect the DCI signaling to be allocated in the time domain of MultiTrans. Multi-Trans Time Domain Allocation The number of SLIVs indicated in the line exceeds 1. In such cases, UE 104 can determine the time-domain allocation of the MultiTrans of the DCI signaling ( t imeDomainAllocationforMultiTran The number of SLIVs indicated in the s) line is 1 or less.

[0052] In some implementations, as part of example method 13, for time-domain allocation configured with the high-level parameter MultiTrans ( Multi-Trans Time Domain Allocation For UE 104, the indicated TCI state(s) can be based on the active TCI state in the first time slot(s) with the scheduled TB(s). In this case, UE 104 can expect (or determine) that the active TCI state is the same in the time slot(s) with the scheduled TB(s).

[0053] For multiple transmissions, as part of example method 14, as discussed above, one or more transmissions in multiple transmissions can be different TBs or a single TB (e.g., a single TB).

[0054] Example 1 of Example Case 1 In some configurations, four different TB of transport can be scheduled, for the purposes of this example. In this case, the MCS index table and TDRA table can be configured as example table 2 and example table 3, respectively.

A new data indicator can occupy 4 bits to indicate whether each transmission in multiple transmissions of different TBs is a new transmission or a retransmission of at least one previous transmission. A redundant version can occupy 4 bits, where the value of each bit can represent / indicate the redundant version of each transmission. The allocation symbol length x1 (e.g., the first allocation symbol length) can correspond to a time slot (e.g., a consecutive time slot) of a transmission of TB1 (e.g., the first transmission in multiple transmissions), whose modulation can be, for example, 16QAM (e.g., the first modulation order). The allocation symbol length x2 (e.g., the second allocation symbol length) can correspond to a consecutive time slot of a transmission of at least one of TB2, TB3, and / or TB4 (e.g., the second transmission in multiple transmissions), whose modulation can be QPSK (e.g., the second modulation order). In this example, x2 can be equal to x1 multiplied by... 16QAM and QPSK modulation are provided as examples, although other modulation orders can also be configured or used in this paper. In some cases, if the time-domain assignment of MultiTrans is not configured ( Multi-Trans Time Domain Allocation If so, time-domain resource allocation, MCS, new data indicators and / or redundant versions can follow the specification (configured or used according to the specification).

[0055] Example 2 of Example Case 1 Similar to the example above, a TB (e.g., a single TB) can schedule four transmissions for the purposes of this example. In some configurations, if MultiTrans's time-domain allocation is configured ( timeDomainAllocationforMult iTrans If ), then the TDRA index in the time domain allocation for MultiTrans can be {(0101), (0010), (0010), (0010), (...} 无效},in I (For example, if a higher-level parameter is configured, it indicates the time-domain allocation of the higher-level parameter MultiTrans.)

The value of each bit can indicate the redundant version for each transmission. The allocated symbol length x1 can correspond to a consecutive time slot of the first transmission in multiple transmissions of a TB, where the modulation can be the first modulation order (e.g., 16QAM or others). The allocated symbol length x2 can correspond to a consecutive time slot of the second (e.g., another, third, fourth, etc.) transmission in multiple transmissions of the same TB, where the modulation can be the second modulation order (e.g., QPSK or others).

[0062] Figure 4 A flowchart of an example method 400 for indicating a transmission scheme is shown. Method 400 can be used in conjunction with this document. Figures 1 to 3 The method 400 may be implemented by any one or more of the components and devices described in detail. In short, in some embodiments, method 400 may be implemented by at least one wireless communication device (e.g., UE or terminal device), at least one wireless communication node (e.g., base station BS, gNB, transceiver point TRP, or access network device), at least one satellite, etc. Depending on the embodiment, additional, fewer, or different operations may be performed in method 400. At least one aspect of these operations relates to a system, method, apparatus, or computer-readable medium.

[0063] At operation 402, the wireless communication node may send / transmit / provide to the wireless communication device a first indication of multiple modulation and coding schemes (MCS) for multiple transmissions of at least one transport block (TB) (or multiple TBs). At operation 404, the wireless communication device may receive / acquire / obtain the first indication from the wireless communication node. At operation 406, the wireless communication device may determine the multiple MCSs for multiple transmissions of at least one TB based on the first indication.

[0064] In some implementations, the first indication may include / contain multiple bit fields to indicate multiple MCS indices corresponding to multiple transmissions (e.g., multiple transmissions). In some implementations, the second indication may be indicated by higher-layer signaling. The second indication may include at least one of the following: a reused or redefined first field indicating a Time Domain Resource Allocation (TDRA) configuration corresponding to multiple Start and Length Indicators (SLIVs) of multiple transmissions; and / or a defined second field indicating a TDRA configuration corresponding to multiple SLIVs of multiple transmissions. For example, the first field may be a reused / redefined / reconfigured existing field to indicate the time domain configuration of multiple transmissions. In another example, the second field may be a new field of higher-layer signaling transmission.

[0065] In some implementations, the wireless communication device can receive a second indication from the wireless communication node. Using at least the second indication and a TDRA table, the wireless communication device can determine multiple SLIVs for at least one TB of multiple transmissions. In certain circumstances, the wireless communication device can use the second indication and the TDRA table to determine multiple SLIVs for at least one TB of multiple transmissions when certain conditions are met. For example, such conditions may include, but are not limited to, a flag field configured via upper-layer signaling, which indicates that the first field is reused or redefined as a configuration indicating the TDRA.

In some configurations, for example, the first modulation may be 16QAM and the second modulation may be QPSK, although other modulation orders may also be used. In this case, x1 may be equal to or correspond to x2, and the number of consecutive time slots may be associated with log2((the first modulation order indicated by the MCS of the first transmission) / (the second modulation order indicated by the MCS of the second transmission)) (e.g., In another example, the first allocated symbol length (x1) may correspond to a time slot of the first transmission using the first modulation order; the second allocated symbol length (x2) may correspond to a time slot of the second transmission using the second modulation order. In this example, x2 may be equal to x1 multiplied by log2((the first modulation order indicated by the MCS of the first transmission) / (the second modulation order indicated by the MCS of the second transmission)).

[0070] In some implementations, for example, if a second indication is configured, the wireless communication device can receive a fourth indication of multiple New Data Indicators (NDIs) from multiple transmissions from the wireless communication node. For example, the second indication might include or correspond to a time-domain allocation of MultiTrans (…). timeDomainAllocationforMultiTrans The fourth indication may include or have a bit width determined based on the maximum number of schedulable transmissions across all entries in the second indication.
