And / or, since the first information field of the DCI carries at least one shared indication information and N TBs, which can satisfy the condition that one shared indication information indicates the first transmission parameter of at least one transmission parameter of at least one TB among the N TBs, and the second transmission parameter of at least one transmission parameter of at least one TB is determined by the third transmission parameter, it can be understood that the second transmission parameters of the N TBs do not need to be indicated by the information fields of the DCI, instead of, as in related technologies, one shared indication information indicating the transmission parameters of one TB. Therefore, when the number of N TBs scheduled by the DCI is large, the DCI does not need to indicate the second transmission parameters of each TB among the N TBs through other information fields.

[0030] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0031] The following will explain the technical terms used in the embodiments of this application.

[0032] 1. New Data Indicator (NDI)

[0033] NDI is an indication message used to indicate whether data transmitted by a user is a new transmission or a retransmission. For DCIs with formats such as format 0-0 or format 1-0, the NDI for a DCI scheduling a Physical Downlink Shared Channel (PDSCH) occupies only 1 bit, and this 1 bit indicates whether the data sent or received on the scheduled PDSCH is a new transmission or a retransmission by whether it is flipped (flipping means whether it is the same as the previous indication; if it is the same, it is flipped; if it is different, it is not).

[0034] Specifically, if this 1-bit flips, it indicates that the data sent or received on the PDSCH is either newly transmitted or retransmitted; if this 1-bit does not flip, it indicates that the data sent or received on the PDSCH is a retransmission. If the data sent or received on the PDSCH is from a Hybrid Automatic Repeat Request (HARQ) process, and this is the first time data from this HARQ process has been received (i.e., there is no corresponding previous NDI), then the data from this HARQ process can be considered newly transmitted data.

[0035] For DCI scheduling of multiple Physical UpLink Shared Channels (PUSCH) / PDSCHs in format 0-1 / format 1-1, the NDI bits depend on the number of maximum start and length indicator values ​​(SLIVs) available for scheduling in all rows of the Time Domain Resource Assignment (TDRA) table configuration.

[0036] In the protocol, NDI is described as follows: If the number of scheduled PUSCHs indicated by TDRA is 1, then the number of bits occupied by NDI is 1 bit; otherwise, 2, 3, 4, 5, 6, 7 or 8 bits are determined according to the maximum number of schedulable PUSCHs in all entries of the higher-layer parameter pusch-TimeDomainAllocationListForMultiPUSCH, where each bit corresponds to a scheduled PUSCH as defined in clause 6.1.4 of [6,TS 38.214].

[0037] It can be understood that each TB of each PUSCH / PDSCH corresponds to one bit of NDI. When NDI corresponds to multiple PDSCH / PUSCH, each bit of the NDI field of DCI corresponds to one TB of one PDSCH / PUSCH.

[0038] 2. Redundancy Version (RV)

[0039] RV is used to implement soft-combining HARQ transmission. This soft-combining can be divided into Chase combining and Incremental Redundancy (IR).

[0040] In Chase combining, the retransmitted content is identical to the original content, so it simply repeats the transmission of the original content without increasing coding gain. Specifically, as shown in Figure 1A, assuming a data packet is transmitted three times, the content 1 of the first transmitted data packet after Chase combining, the content 2 of the second transmitted data packet after Chase combining, and the content 3 of the third transmitted data packet after Chase combining are identical.

[0041] In Interconnection (IR), the content of each retransmission does not need to be the same as the original content. Each transmission uses a different encoding than the previous one. Because retransmissions contain some bits that were not in the previous transmission, the bit rate will be relatively low. Furthermore, the modulation scheme may also be different. Specifically, as shown in Figure 1B, assuming a data packet is transmitted three times, the encoding used for the content 1 after the first transmission (Chase Combining) is different from the encoding used for the content 2 after the second transmission (Chase Combining), and the encoding used for the content 3 after the third transmission (Chase Combining) is also different.

The transmit power control of the Planned Physical Uplink Control Channel (PUCCH) is also specified. The Control (TPC) indicator is used to indicate the transmit power of the PUCCH corresponding to the DCI. The PUCCH resource indicator indicates the resources of the PUCCH corresponding to the DCI. The PDSCH-to-HARQ_feedback timing indicator indicates the HARQ feedback time of the PDSCH corresponding to the DCI. The one-time HARQ-ACK request indicates whether the TB scheduled by the DCI should perform one-time HARQ feedback. The enhanced Type 3 codebook indicates the codebook corresponding to the TB scheduled by the DCI. The HARQ-ACK retransmission indicator indicates whether the TB scheduled by the DCI should perform HARQ-ACK retransmission. The antenna port indicates the antenna port corresponding to the TB scheduled by the DCI. The gearbox configuration indicator indicates the gearbox configuration corresponding to the TB scheduled by the DCI. The uplink channel sounding reference signal (SRS) request indicates the SRS associated with the DCI. The SRS offset indicator indicates the offset value of the SRS associated with the DCI.

Signal (DMRS) sequence initialization indicates the initialization method of the DMRS sequence corresponding to the TB scheduled by DCI; priority indication indicates the transmission priority of the TB scheduled by DCI; ChannelAccess-CPext indicates the channel access method of the TB scheduled by DCI; minimum applicable scheduling offset indication indicates the minimum scheduling offset of the TB scheduled by DCI.The Secondary Cell (SCell) sleep indicator indicates whether the SCell corresponding to the DCI is in sleep mode. The PDCCH monitoring adaptive indicator indicates the monitoring mode of the PDCCH corresponding to the DCI. The PUCCH cell indicator indicates the cell to which the PUCCH corresponding to the DCI belongs. The total size of the Cyclical Redundancy Check (CRC) indicates the number of bits excluding the CRC.

[0048] Among them, single PDSCH scheduling (bits) is used to indicate the case when DCI schedules one PDSCH; type is used to indicate the type corresponding to different entries; scheduling of 2 cells, each cell has 2 PDSCHs (bits) to indicate the case when DCI schedules 2 cells and each cell has 2 PDSCHs; scheduling of 2 cells, each cell has 4 PDSCHs (bits) to indicate the case when DCI schedules 2 cells and each cell has 4 PDSCHs; scheduling of 2 cells, each cell has 8 PDSCHs (bits) to indicate the case when DCI schedules 2 cells and each cell has 8 PDSCHs.

[0049] 4. De-enable TB's DCI instruction

[0050] If the higher-level parameter maxNrofCodeWordsScheduledByDCI in the PDSCH-config indicates that dual codeword transmission is enabled, then in I MCS When rvid=1 for the corresponding transport block and =26, disabling one of the two transport blocks via a DCI in the format 1_1 or 1_3 can be understood as the MCS instruction carried by the Modulation and Coding Scheme (MCS) field of the DCI being used to enable one of the two transport blocks.

[0051] If the higher-level parameter maxNrofCodeWordsScheduledByDCI in PDSCH-ConfigMulticast indicates that dual codeword transmission is enabled, then if I MCS =26 and the corresponding transport block's rvid=1, then one of the two transport blocks is disabled by a DCI of format 4_2. It can be understood that the MCS field of this DCI carries the MCS instruction to enable one of the two transport blocks.

[0052] When the terminal is configured with the higher-level parameter pdsch-TimeDomainAllocationListForMultiPDSCH, if I MCSIf rvid=26 and the corresponding transport block of all scheduled PDSCHs has rvid=2, then the first or second transport block of all scheduled PDSCHs is disabled via DCI of format 1_1. If two transport blocks are enabled, transport blocks 1 and 2 are mapped to symbols 0 and 1, respectively. If only one transport block is enabled, the enabled transport block is always mapped to the first symbol.

[0053] It should be noted that the above I MCS The value of the MCS field used to indicate the DCI is given by rvid, which is used to indicate the value of the RV field used to indicate the DCI.

[0059] The information transmission method, apparatus, terminal, network-side device, and readable storage medium provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0060] Figure 2 shows a flowchart illustrating the information transmission method provided in an embodiment of this application. As shown in Figure 2, the information transmission method provided in an embodiment of this application may include the following steps 101 and 102.

[0061] Step 101: The terminal receives DCI from the network-side device.

[0062] In some embodiments of this application, the format of the DCI can be any of the following: DCI format 0-3, DCI format 1-3. Of course, the format of the DCI can also be other formats, and this application does not limit this.

[0063] In this embodiment of the application, the DCI is used to schedule N TBs. The first information field of the DCI carries at least one shared indication information, which is used to determine at least one transmission parameter for each TB, where N is a positive integer greater than or equal to 2.

[0064] In some embodiments of this application, the first information field includes at least one of the following: a New Data Indicator (NDI) field, a Redundancy Version (RV) field, and a Modulation and Coding Scheme (MCS) field. Of course, the first information field can also be other fields, and this application does not limit this.

[0065] Thus, since the embodiments of this application specify the possible information fields of the first information field, both the terminal and the network-side device can know the information field carrying at least one shared instruction information without additional instruction, thereby reducing instruction overhead.

[0066] In some embodiments of this application, each Y bit in the first information field described above can carry a shared indication information. Each shared indication information can indicate at least one TB of transmission parameters, where Y is a positive integer.

[0067] In some embodiments of this application, the aforementioned at least one transmission parameter includes at least one of the following: a new data indication, a redundancy version, and a modulation and coding scheme. The new data indication is used to indicate whether the corresponding TB is an initial transmission or a retransmission.

[0068] In this embodiment of the application, at least one of the following conditions is satisfied between the above-mentioned at least one shared indication information and the N TBs:

[0069] A shared indication information indicates the first transmission parameter in at least one transmission parameter of at least two of the N TBs;

[0070] A shared indication information indicates a first transmission parameter and a second transmission parameter in at least one transmission parameter of at least one TB among N TBs;

[0071] A shared indication information indicates a first transmission parameter in at least one transmission parameter of at least one of the N TBs, and a second transmission parameter in at least one transmission parameter of at least one TB is determined by a third transmission parameter, which is a transmission parameter associated with the N TBs.

[0072] In some embodiments of this application, when the first information field includes an NDI field, the first transmission parameter can be a new data indication corresponding to the TB. When the first information field includes an RV field, the first transmission parameter can be a redundant version of the corresponding TB. When the first information field includes an MCS field, the first transmission parameter can be the modulation and coding scheme of the corresponding TB.

[0073] In some embodiments of this application, when the first information field includes an NDI field, the second transmission parameter can be a redundant version of the corresponding TB, or a modulation and coding scheme for the corresponding TB. When the first information field includes an RV field, the second transmission parameter can be a new data indication for the corresponding TB, or a modulation and coding scheme for the corresponding TB. When the first information field includes an MCS field, the second transmission parameter can be a new data indication for the corresponding TB, or a redundant version of the corresponding TB.

[0074] It is understandable that the second transmission parameter is different from the first transmission parameter.

[0075] The following examples illustrate the relationship between at least one shared instruction message and N TBs.

[0076] Example 1: At least one shared indication information and N TBs satisfy the condition that a shared indication information indicates the first transmission parameter of at least two of the N TBs in at least one transmission parameter.

[0077] In some embodiments of this application, the above-mentioned N TBs are transmitted through T channels of M frequency domain units, each of the M frequency domain units including at least one channel, where M is a positive integer less than N and T is a positive integer less than N and greater than or equal to M.

[0078] It can be understood that the above DCI is used to schedule the transmission of N TBs in T channels across M frequency domain units.

[0079] It should be noted that the term "transmission" above can be understood as sending and / or receiving.

[0080] In some embodiments of this application, the frequency domain unit includes at least one of the following: cell, carrier, frequency domain resource pool, bandwidth portion, continuous frequency domain resources, etc. Of course, the frequency domain unit may also include other units, and this application embodiment does not limit this.

[0081] In some embodiments of this application, the aforementioned channel can be any of the following: a data sharing channel, a control channel, etc., wherein the data sharing channel may include at least one of the following: PDSCH, PUSCH. Of course, the data sharing channel may also include other channels, and this application embodiment does not limit this. The control channel may include at least one of the following: PDCCH, PUCCH. Of course, the control channel may also include other channels, and this application embodiment does not limit this.

[0082] It should be noted that the aforementioned channels may also include other channels, but this application embodiment does not limit them.

[0083] In this embodiment of the application, the aforementioned shared indication information indicates a first transmission parameter among at least two transmission parameters of the N TBs, including at least one of the following:

[0084] A shared indication information indicates the first transmission parameter of a TB transmitted on a channel;

[0085] A shared indication information indicates the first transmission parameters of the TB transmitted by at least one channel of a frequency domain unit;

[0086] A shared indication information indicates the first transmission parameters of TB for all channel transmissions of at least some of the M frequency domain units.

[0087] In some embodiments of this application, the first transmission parameter of a TB transmitted on a channel indicated by the aforementioned shared indication information can be understood as: the first transmission parameter indicated by a shared indication information can be applied to different TBs transmitted on the same channel.

[0088] In some embodiments of this application, when a shared indication information indicates the first transmission parameter of a channel transmission TB, if the first information field is an NDI field, the number of bits occupied by a shared indication information can be 1; if the first information field is an RV field, the number of bits occupied by a shared indication information can be 1 or 2; if the first information field is an MCS field, the number of bits occupied by a shared indication information can be 5.

[0089] Case 1: A shared indication information indicates the first transmission parameter of a TB transmitted on a channel.

[0090] In some embodiments of this application, the aforementioned at least one shared indication information includes first shared indication information. The aforementioned shared indication information indicates a first transmission parameter of a TB transmitted on a channel, including any of the following:

[0091] When the first frequency domain unit to which the first channel corresponding to the first shared indication information belongs is configured with spatial multiplexing and the first frequency domain unit is configured with dual codewords, the first shared indication information indicates the first transmission parameters of the first TB and the second TB transmitted by the first channel.

[0092] When the first frequency domain unit to which the first channel corresponding to the first shared indication information belongs is configured with spatial multiplexing and the first frequency domain unit is not configured with dual codewords, the first shared indication information indicates the first transmission parameters of the first TB transmitted by the first channel.

[0093] If the first frequency domain unit to which the first channel corresponding to the first shared indication information belongs is configured with spatial multiplexing and the first frequency domain unit is configured with dual codewords, and if the first shared indication information also indicates to disable TB, then the first shared indication information indicates the first transmission parameters of the first TB transmitted by the first channel.

[0094] The first shared indication information indicates the first transmission parameters of the first TB transmitted on the first channel, and the first shared indication information and the second information field of the DCI indicate the first transmission parameters of the second TB transmitted on the first channel.

[0095] In some embodiments of this application, the aforementioned first shared indication information can be any one of the at least one shared indication information. The aforementioned first shared indication information can be used to indicate the first transmission parameters of the TB transmitted on the first channel.

[0096] In some embodiments of this application, the first channel may include at least one of the following: PDSCH, PUSCH.

[0097] In some embodiments of this application, the first frequency domain unit may include at least one of the following: cell, carrier, frequency domain resource pool, bandwidth portion, continuous frequency domain resources, etc. For example, the first frequency domain unit may be a cell.

[0098] In some embodiments of this application, the aforementioned first TB can be either the first TB or the second TB transmitted through the first channel. The aforementioned second TB can be either the second TB or the first TB transmitted through the first channel. It is understood that the first TB and the second TB are different TBs.

[0099] In some embodiments of this application, when the first information field includes the MCS field, if the value of the first shared indication information is a predetermined value, it can be considered that the first shared indication information also indicates to enable TB.

[0100] In some embodiments of this application, the second information field may include at least one of the following: NDI field, RV field, MCS field, differential indicator field, etc. Of course, the second information field may also include other information fields of the DCI, and this application embodiment does not limit this. For example, the second information field may be a differential indicator field.

[0101] In some embodiments of this application, the first transmission parameter of the second TB can be calculated using a predefined algorithm based on the first transmission parameter indicated by the first shared indication information and the value of the second information field. The predefined algorithm satisfies at least one of the following: configured by the network-side device, agreed upon by the protocol, or determined by the terminal.

[0102] For example, assuming the first information field is the RV field and the value of the first shared indication information is "00", and the second information field is the differential indication field, if the bit value of the second information field is "0", it means that the RV of the second TB is "00"; if the bit value of the second information field is "1", it means that the RV of the second TB is "01".

[0103] For example, suppose the first information field is the MCS field, and the value of the first shared indication information is "10110". The second information field is the differential indication field. If the bit value of the second information field is "0", it means that the MCS of the second TB is "10110"; if the bit value of the second information field is "1", it means that the MCS of the second TB is "10111".

[0104] Thus, since the embodiments of this application specify the conditions that the first shared indication information (i.e. any shared indication information) in the at least one shared indication information must satisfy when a shared indication information indicates the first transmission parameters of a TB transmitted on a channel, the terminal and network-side equipment do not need additional indications. They can determine the relationship between at least one shared indication information and N TBs based on the conditions, thereby reducing indication overhead.

[0105] As can be seen from the above, in Case 1, a shared indication information indicates the first transmission parameter of a TB transmitted on a channel, instead of the general case in related technologies where one indication information indicates the transmission parameters of one TB. In other words, compared to related technologies, in this case, a shared indication information can indicate the transmission parameters of more TBs, thereby reducing the overhead of DCI.

[0106] Case 2: A shared indication information indicates the first transmission parameters of the TB transmitted by at least one channel of a frequency domain unit.

[0107] In some embodiments of this application, the aforementioned at least one shared indication information further includes second shared indication information. The aforementioned shared indication information indicates the first transmission parameters of the TB transmitted by at least one channel of a frequency domain element, including at least one of the following:

[0108] The second shared indication information indicates the first transmission parameters of TB for all channel transmissions in the scheduling of the second frequency domain unit in the M frequency domain units;

[0109] The number of second shared indication information is at least two, and each second shared indication information indicates the first transmission parameter of the TB of channel transmission in one of the at least two channel groups;

[0110] The second shared indication information indicates the first transmission parameters of the TB for channel transmission in the first channel group, and the second information field of the second shared indication information and DCI indicates the first transmission parameters of the TB for channel transmission in other channel groups.

[0111] In some embodiments of this application, the aforementioned second shared indication information can be any one of at least one shared indication information. This second shared indication information may be different from the first shared indication information.

[0112] In some embodiments of this application, at least one channel of a frequency domain unit can be all channels scheduled by the frequency domain unit, or channels belonging to the same group of the frequency domain unit.

[0113] In this embodiment of the application, the above-mentioned at least two channel groups are channel groups associated with the second frequency domain unit among the M frequency domain units.

[0114] In some embodiments of this application, the aforementioned second frequency domain unit can be one of the M frequency domain units corresponding to the second shared indication information. The frequency domain unit corresponding to each second shared indication information can be determined by the terminal, configured by the network-side device, or agreed upon by the protocol.

[0115] In some embodiments of this application, the first transmission parameter of the TB of all channel transmissions of the second frequency domain unit in the scheduling of the second frequency domain unit in the above-mentioned second shared indication information can be understood as: the first transmission parameter indicated by the second shared indication information can be applied to the TB of different channel transmissions of the scheduling of the second frequency domain unit.

[0116] In some embodiments of this application, each of the above-mentioned at least two channel groups may include at least one channel of the second frequency domain unit. The at least two channel groups may be channel groups configured by the network-side device for the terminal. The granularity of the configuration of the number of the at least two channel groups may be at least one of the following: per serving cell, per Physical Uplink Control Channel (PUCCH) group, per cell set, per serving cell group, and per Bandwidth Part (BWP).

[0117] In some embodiments of this application, the first transmission parameter of the TB of channel transmission in one of the at least two channel groups indicated by each second shared indication information can be understood as: the first transmission parameter indicated by each second shared indication information can be applied to the TB of different channel transmissions in a channel.

[0118] In some embodiments of this application, the channel group corresponding to each second shared indication information can be determined by the terminal, configured by the network-side device, or agreed upon by the protocol.

[0119] In this embodiment of the application, the first channel group is a channel group among at least two channel groups, and the other channel groups are channel groups other than the first channel group among at least two channel groups.

[0120] In some embodiments of this application, the second information field may include at least one of the following: NDI field, RV field, MCS field, differential indicator field, etc. Of course, the second information field may also include other information fields of DCI, which are not limited in this application embodiment.

[0121] For example, the second information field can be a differential indication field.

[0122] In some embodiments of this application, the aforementioned first channel group can be the channel group corresponding to the second shared indication information among at least two channel groups, such as the first channel group among at least two channel groups. The channel group corresponding to each second shared indication information can be determined by the terminal, indicated by the network-side device, or agreed upon by the protocol.

[0123] In some embodiments of this application, the first transmission parameter of the TB for channel transmission in other channel groups can be calculated using a predefined algorithm based on the values ​​of the first transmission parameter indicated by the second shared indication information and the second information field. This predefined algorithm satisfies at least one of the following: configured by the network-side device, agreed upon by the protocol, or determined by the terminal.

[0124] Thus, since the embodiments of this application specify the conditions that the second shared indication information (i.e. any shared indication information) in the at least one shared indication information must satisfy when a shared indication information indicates the first transmission parameters of at least one channel of a frequency domain unit transmitted, the terminal and network-side equipment do not need additional indication, and can determine the relationship between at least one shared indication information and N TBs based on the conditions. Therefore, the indication overhead can be reduced.

[0125] In some embodiments of this application, the quantity of the second shared indication information described above satisfies any one of the following:

[0126] Determined by the number of at least two channel groups;

[0127] When the terminal is configured to use time-domain binding for hybrid automatic repeat request (HARQ) feedback, the response is determined by the HARQ group configured on the terminal.

[0128] In some embodiments of this application, the number of the above-mentioned at least two channel groups may be the same as the number of second shared indication information.

[0129] In some embodiments of this application, when the terminal is configured with the parameter `nrofHARQ-BundlingGroups` for time bundling feedback of HARQ, it can be considered that the terminal is configured to use time bundling for hybrid automatic repeat request (HARQ) feedback. The granularity of the `nrofHARQ-BundlingGroups` configuration includes at least one of the following: per serving cell, per PUCCH group, per cell set, per serving cell group, and per BWP.

[0130] In some embodiments of this application, the number of the above-mentioned at least two channel groups may be the same as the number of HARQ packets.

[0131] Thus, since the embodiments of this application specify the conditions that the quantity of the second shared indication information must meet, both the terminal and the network-side device can accurately determine the quantity of the second shared indication information without additional indication, thereby reducing indication overhead.

[0132] In some embodiments of this application, the maximum number of channels in each of the at least two channel groups satisfies at least one of the following:

[0133] It is determined by the maximum number of SLIVs corresponding to the frequency domain unit group to which the channels belong in at least two channel groups and the number of groups in at least two channel groups;

[0134] It is determined by the maximum number of SLIVs corresponding to the frequency domain unit to which the channel in each channel group belongs and the number of groups with at least two channel groups;

[0135] It is determined by the actual number of SLIVs corresponding to the frequency domain units to which the channels in each channel group belong and the number of groups of at least two channel groups.

[0136] In this embodiment of the application, the maximum number of SLIVs corresponding to the frequency domain unit group to which the channels in the above at least two channel groups belong is determined by at least one of the following: the time domain resource allocation (TDRA) table corresponding to the DCI, the actual scheduled frequency domain unit indicated by the third information field of the DCI, and the frequency domain unit group table corresponding to the DCI.

[0137] In some examples, the TDRA table corresponding to the DCI can be understood as the TDRA table carried in the DCI. The third information field can be a scheduling frequency domain unit indication information field, which is used to indicate the actual scheduled frequency domain unit. Of course, this third information field can also be other information fields, and this application embodiment does not limit this. The frequency domain unit group table corresponding to the DCI can be understood as the frequency domain unit group table carried in the DCI.

[0138] In some embodiments of this application, when the maximum number of channels in each channel group is determined by the maximum number of SLIVs corresponding to the frequency domain unit groups to which the channels in at least two channel groups belong and the number of groups in at least two channel groups, the maximum number of channels in each channel group can be: the number obtained by dividing the maximum number of SLIVs corresponding to the frequency domain unit groups to which the channels in at least two channel groups belong by the number of groups in at least two channel groups and rounding it up.

[0139] For example, assuming the first information domain is the NDI domain and the second frequency domain unit is a cell set, which includes serving cell 1 and serving cell 2, the network-side device configures at least two channel groups for the terminal at a per-cell-set granularity, with a group size of 2. The channels of serving cell 1 belong to one channel group, and the channels of serving cell 2 belong to another channel group. The number of second shared indication information is 4, such as shared indication information 1, shared indication information 2, shared indication information 3, and shared indication information 4. Shared indication information 1 occupies 1 bit, shared indication information 2 occupies 1 bit, shared indication information 3 occupies 1 bit, and shared indication information 4 occupies 1 bit. According to the TDRA table configuration, the maximum number of SLIVs in a cell set is 8, so the maximum number of channels in each channel group can be 8 / 2, that is, the maximum number of channels in each channel group can be 4. If the actual scheduled number of SLIVs for serving cell 1 is 6, then shared indication information 1 corresponds to 4 channels of serving cell 1, and shared indication information 2 corresponds to 2 channels of serving cell 1. If the actual number of SLIVs scheduled for serving cell 2 is 4, then shared indication information 3 corresponds to 4 channels of serving cell 1, and shared indication information 4 corresponds to 0 channels of serving cell 1.

[0140] In some embodiments of this application, when the maximum number of channels in each channel group is determined by the maximum number of SLIVs corresponding to the frequency domain units to which the channels in each channel group belong and the number of at least two channel groups, the maximum number of channels in each channel group can be: the number obtained by dividing the maximum number of SLIVs corresponding to the frequency domain units to which the channels in each channel group belong by the number of at least two channel groups and rounding it up.

[0141] For example, assuming the first information domain is the NDI domain and the second frequency domain unit is a cell, which includes serving cell 1 and serving cell 2, the network-side device configures two channel groups for serving cell 1 and one channel group for serving cell 2 at a per-cell granularity. The number of second shared indication information is three, such as shared indication information 1, shared indication information 2, and shared indication information 3. Shared indication information 1 occupies 1 bit, shared indication information 2 occupies 1 bit, and shared indication information 3 occupies 1 bit. According to the TDRA table configuration, the maximum number of SLIVs for serving cell 1 is 8. Therefore, the maximum number of channels in each channel group to which the channel of serving cell 1 belongs can be 8 / 2, that is, the maximum number of channels in each channel group to which the channel of serving cell 1 belongs can be 4. If the actual number of SLIVs scheduled for serving cell 1 is 6, then shared indication information 1 corresponds to 4 channels of serving cell 1, and shared indication information 2 corresponds to 2 channels of serving cell 1. If the maximum number of SLIVs of serving cell 2 is 6, then the maximum number of channels in a channel group to which the channel of serving cell 2 belongs can be 6 / 1. That is, the maximum number of channels in a channel group to which the channel of serving cell 2 belongs can be 6. If the actual number of SLIVs of serving cell 2 scheduled is 6, then the shared indication information 3 corresponds to the 6 channels of serving cell 2.

[0142] In some embodiments of this application, when the maximum number of channels in each channel group is determined by the maximum number of SLIVs corresponding to the frequency domain unit groups to which the channels in at least two channel groups belong and the number of at least two channel groups, or by the maximum number of SLIVs corresponding to the frequency domain units to which the channels in each channel group belong and the number of at least two channel groups, the terminal can first determine the maximum number of SLIVs corresponding to the scheduled cell combination based on the actual scheduled frequency domain units indicated by the third information domain, or determine the maximum number of SLIVs corresponding to each cell in the scheduled cell combination, and then divide the maximum number of SLIVs by the number of at least two channel groups and round up to obtain the maximum number of channels for each channel group.

[0143] For example, assuming the first information domain is the NDI domain and the second frequency domain unit is a cell set, which includes serving cell 1 and serving cell 2, the network-side device configures at least two channel groups for the terminal at a per-cell-set granularity, with a group size of 2. The channels of serving cell 1 belong to one channel group, and the channels of serving cell 2 belong to another channel group. The number of second shared indication information is 4, such as shared indication information 1, shared indication information 2, shared indication information 3, and shared indication information 4. Shared indication information 1 occupies 1 bit, shared indication information 2 occupies 1 bit, shared indication information 3 occupies 1 bit, and shared indication information 4 occupies 1 bit. Based on the third information domain indicating the actual scheduled frequency domain unit, the maximum number of SLIVs corresponding to this cell set is determined to be 8. Therefore, the maximum number of channels in each channel group can be 8 / 2, that is, the maximum number of channels in each channel group can be 4. If the actual scheduled number of SLIVs for serving cell 1 is 6, then shared indication information 1 corresponds to 4 channels of serving cell 1, and shared indication information 2 corresponds to 2 channels of serving cell 1. If the actual number of SLIVs of the serving cell 2 is 2, then the shared indication information 3 corresponds to the 2 channels of the serving cell 2, and the shared indication information 4 corresponds to 0 channels.

[0144] For example, assuming the first information domain is the NDI domain and the second frequency domain unit is a cell, which includes serving cell 1 and serving cell 2, the network-side device configures two channel groups for serving cell 1 and one channel group for serving cell 2 at a per-cell granularity. The number of second shared indication information is three, such as shared indication information 1, shared indication information 2, and shared indication information 3. Shared indication information 1 occupies 1 bit, shared indication information 2 occupies 1 bit, and shared indication information 3 occupies 1 bit. Based on the third information domain indicating the actual scheduled frequency domain unit, it is determined that the maximum number of SLIVs corresponding to serving cell 1 in the scheduled cell combination is 8, and the maximum number of SLIVs corresponding to serving cell 2 is 6. Then, the maximum number of channels in each channel group to which the channel of serving cell 1 belongs is 8 / 2, that is, the maximum number of channels in each channel group to which the channel of serving cell 1 belongs is 4, and the maximum number of channels in each channel group to which the channel of serving cell 2 belongs is 6 / 1, that is, the maximum number of channels in each channel group to which the channel of serving cell 2 belongs is 6. If the actual number of SLIVs scheduled for serving cell 1 is 6, then shared indication information 1 corresponds to 4 channels of serving cell 1, and shared indication information 2 corresponds to 2 channels of serving cell 1. If the maximum number of SLIVs for serving cell 2 is 6, then shared indication information 1 corresponds to 6 channels of serving cell 2.

[0145] In some embodiments of this application, when the maximum number of channels in each channel group is determined by the actual number of SLIVs corresponding to the frequency domain units to which the channels in each channel group belong and the number of at least two channel groups, the maximum number of channels in each channel group is: the number obtained by dividing the actual number of SLIVs corresponding to the frequency domain units to which the channels in each channel group belong by the number of at least two channel groups and rounding it up.

[0146] For example, assuming the first information domain is the NDI domain and the second frequency domain unit is a cell, which includes serving cell 1 and serving cell 2, the network-side device configures two channel groups for serving cell 1 and one channel group for serving cell 2 at a per-cell granularity. The number of second shared indication information is three, such as shared indication information 1, shared indication information 2, and shared indication information 3. Shared indication information 1 occupies 1 bit, shared indication information 2 occupies 1 bit, and shared indication information 3 occupies 1 bit. Based on the third information domain indicating the actual scheduled frequency domain unit, it is determined that the actual number of SLIVs corresponding to serving cell 1 in the scheduled cell combination is 8, and the actual number of SLIVs corresponding to serving cell 2 is 6. Then, the maximum number of channels in each channel group to which the channel of serving cell 1 belongs is 8 / 2, that is, the maximum number of channels in each channel group to which the channel of serving cell 1 belongs is 4, and the maximum number of channels in each channel group to which the channel of serving cell 2 belongs is 6 / 1, that is, the maximum number of channels in each channel group to which the channel of serving cell 2 belongs is 6.

[0147] Thus, since the embodiments of this application specify the conditions that the maximum number of channels in each of the at least two channel groups must meet, the terminal and network-side devices can accurately determine the maximum number of channels in each channel group based on these conditions without additional indication, thereby reducing indication overhead.

[0148] As can be seen from the above, in Case 2, a shared indication information indicates the first transmission parameter of TB transmitted by at least one channel of a frequency domain unit, and each channel transmits at least two TBs. That is, in Case 2, a shared indication information indicates at least two TBs of transmission parameters, instead of, as in related technologies, one indication information indicates one TB of transmission parameters. In other words, compared with related technologies, in this case, a shared indication information can indicate more TBs of transmission parameters, thereby reducing the overhead of DCI.

[0149] Case 3: A shared indication information indicates the first transmission parameters of TB for all channel transmissions of at least some of the M frequency domain units.

[0150] In some embodiments of this application, the aforementioned at least one shared indication information further includes third shared indication information. The aforementioned shared indication information indicates the first transmission parameters of the TB for all channel transmissions of at least a portion of the M frequency domain elements, including at least one of the following:

[0151] The third shared indication information indicates the first transmission parameters of TB transmitted by M frequency domain units;

[0152] The number of third shared indication information is at least two, and each third shared indication information indicates the first transmission parameter of the TB transmitted by the frequency domain unit in one of the at least two frequency domain unit groups;

[0153] The third shared indication information indicates the first transmission parameters of the TB transmitted by the frequency domain units in the first frequency domain unit group, and the third shared indication information and the second information field of the DCI indicate the first transmission parameters of the TB transmitted by the frequency domain units in other frequency domain unit groups.

[0154] In some embodiments of this application, the aforementioned third sharing indication information can be any one of at least one shared indication information. This third sharing indication information may differ from the first shared indication information, and may also differ from the second shared indication information.

[0155] In some embodiments of this application, the first transmission parameters of the TB transmitted by the third shared indication information in the M frequency domain units can be understood as follows: the first transmission parameters indicated by the third shared indication information can be applied to the TB transmitted in the channel of different frequency domain units in the M frequency domain units.

[0156] In some embodiments of this application, the aforementioned first frequency domain unit group can be the frequency domain unit group corresponding to the third indication information from at least two frequency domain unit groups. The frequency domain unit group corresponding to each third indication information can be determined by the terminal, indicated by the network-side device, or agreed upon by a protocol.

[0157] In this embodiment of the application, the above-mentioned at least two frequency domain unit groups satisfy any one of the following: a frequency domain unit group obtained by grouping M frequency domain units, or a frequency domain unit group determined by the HARQ group configured by the terminal; the above-mentioned first frequency domain unit group is a frequency domain unit group among the at least two frequency domain unit groups; the above-mentioned other frequency domain unit groups are frequency domain unit groups other than the first frequency domain unit group among the at least two frequency domain unit groups.

[0158] Thus, since the embodiments of this application specify the conditions that the third shared indication information (i.e. any shared indication information) in the at least one shared indication information must satisfy when a shared indication information indicates the first transmission parameters of at least one channel of a frequency domain unit transmitted by a first transmission parameter of a TB, the terminal and network side devices do not need additional indications and can determine the relationship between at least one shared indication information and N TBs based on the conditions, thereby reducing indication overhead.

[0159] In some embodiments of this application, when at least two frequency domain cell groups are frequency domain cell groups obtained by grouping M frequency domain cells, the at least two frequency domain cell groups are obtained based on at least one of the following grouping methods:

[0160] The frequency range in which a frequency domain unit is located;

[0161] The sub-carrier spacing (SCS) corresponding to the frequency domain unit;

[0162] The duplex mode corresponding to the frequency domain unit;

[0163] Does the frequency domain unit belong to the licensed spectrum?

[0164] The relationship between the bandwidth of a frequency domain unit and its bandwidth threshold;

[0165] Index of frequency domain cells;

[0166] The frequency point corresponding to the frequency domain unit.

[0167] In some examples, assuming that at least two frequency domain cell groups are obtained by grouping the frequency domain cells based on the frequency range in which the frequency domain cells are located, then the frequency domain cells belonging to frequency range (FR)1 can be grouped into one group, and the frequency domain cells belonging to FR2 can be grouped into another group.

[0168] In some examples, assuming that at least two frequency domain unit groups are obtained by grouping based on the subcarrier spacing (SCS) corresponding to the frequency domain units, then the frequency domain units with the corresponding SCS as the first preset SCS can be grouped into one group, and the frequency domain units with the corresponding SCS as the second preset SCS can be grouped into another group.

[0169] In some examples, assuming that at least two frequency domain unit groups are obtained by grouping based on the duplex mode corresponding to the frequency domain units, the frequency domain units corresponding to Time Division Duplex (TDD) can be grouped into one group, and the frequency domain units corresponding to Frequency Division Duplex (FDD) can be grouped into another group.

[0170] In some examples, assuming that at least two frequency domain cell groups are obtained based on whether the frequency domain cells belong to the licensed spectrum, then frequency domain cells belonging to the licensed spectrum can be grouped into one group, and frequency domain cells belonging to the unlicensed spectrum can be grouped into another group.

[0171] In some examples, assuming that at least two frequency domain cell groups are obtained by grouping based on the relationship between the bandwidth of the frequency domain cells and the bandwidth threshold, then frequency domain cells with bandwidth less than (or less than or equal to) the bandwidth threshold can be grouped into one group, and frequency domain cells with bandwidth greater than or equal to (or greater than) the bandwidth threshold can be grouped into another group.

[0172] In some examples, assuming that at least two frequency domain unit groups are grouped based on the index of the frequency domain unit and / or the frequency point corresponding to the frequency domain unit, the number of frequency domain units in each frequency domain unit group can be determined first according to the number of frequency domain units actually scheduled indicated by the third information field of the DCI. For example, the number of frequency domain units actually scheduled can be divided by the number of groups of at least two frequency domain unit groups and rounded up. Then, the M frequency domain units are sorted according to a predefined order, and based on the sorted M frequency domain units and the number of frequency domain units in each frequency domain unit group, the M frequency domain units are divided into at least two frequency domain unit groups.

[0173] For example, assuming that the third information field of the DCI indicates that the number of frequency domain units actually scheduled is 5, the number of at least two frequency domain unit groups is 2, the number of frequency domain units in the first frequency domain unit group is 3, and the number of frequency domain units in the second frequency domain unit group is 2, then the 5 frequency domain units can be sorted in ascending (or descending) order of their indexes, and the first three frequency domain units after sorting are determined as the frequency domain units in the first frequency domain unit group, and the last two frequency domain units are determined as the frequency domain units in the second frequency domain unit group.

[0174] For example, assuming that the third information field of the DCI indicates that the number of frequency domain units actually scheduled is 5, the number of at least two frequency domain unit groups is 2, the number of frequency domain units in the first frequency domain unit group is 3, and the number of frequency domain units in the second frequency domain unit group is 2, then the 5 frequency domain units can be sorted in order of frequency points corresponding to the frequency units from low to high (or from high to low), and the first three frequency domain units after sorting are determined as the frequency domain units in the first frequency domain unit group, and the last two frequency domain units are determined as the frequency domain units in the second frequency domain unit group.

[0175] Thus, since the embodiments of this application specify the specific parameters on which the grouping is based to obtain at least two frequency domain unit groups, the terminal and network side devices can accurately divide the M frequency domain units into at least two frequency domain unit groups based on the specific parameters without additional instructions, thereby reducing instruction overhead.

[0176] In some embodiments of this application, the number of the aforementioned third shared indication information is determined by the number of at least two frequency domain unit groups.

[0177] In some embodiments of this application, the number of the aforementioned third shared indication information may be equal to the number of at least two frequency domain unit groups.

[0178] Thus, since the embodiments of this application specify that the number of third shared indication information is determined by the number of at least two frequency domain unit groups, the terminal can accurately determine the number of third shared indication information based on the number of the at least two frequency domain unit groups.

[0179] In some embodiments of this application, the maximum number of frequency domain units in each of the above-mentioned at least two frequency domain unit groups satisfies at least one of the following:

[0180] The number of frequency domain units actually scheduled is determined by the third information domain of the DCI;

[0181] The number of frequency domain units is determined by the maximum number of frequency domain units scheduled by DCI.

[0182] In some embodiments of this application, when the maximum number of frequency domain units in each frequency domain unit group satisfies the number of frequency domain units actually scheduled as indicated by the third information field of the DCI, the maximum number of frequency domain units in each frequency domain unit group can be: the number of frequency domain units actually scheduled as indicated by the third information field of the DCI divided by the number of groups of at least two frequency domain unit groups, and the result is rounded up.

[0183] In some embodiments of this application, when the maximum number of frequency domain units in each frequency domain unit group is determined by the maximum number of frequency domain units scheduled by the DCI, the maximum number of frequency domain units in each frequency domain unit group can be: the number obtained by dividing the maximum number of frequency domain units scheduled by the DCI by the number of groups of at least two frequency domain unit groups and rounding up.

[0184] Thus, since the embodiments of this application specify the specific conditions that the maximum number of frequency domain units in each frequency domain unit group must meet, the terminal and network-side devices can accurately determine the maximum number of frequency domain units in each frequency domain unit group based on these specific conditions without additional instructions, thereby reducing instruction overhead.

[0185] In summary, when N TBs are transmitted through T channels with M frequency domain units, at least one shared indication information and N TBs can satisfy the condition that one shared indication information indicates the first transmission parameters of one TB transmitted through one channel, and the number of TBs transmitted through one channel is at least two. That is, one shared indication information indicates the first transmission parameters of at least two TBs. It can be understood that one shared indication information can indicate the first transmission parameters of a large number of TBs, rather than, as is the case in related technologies, one shared indication information indicates the transmission parameters of one TB. Therefore, the number of bits in the DCI payload can be reduced, thereby reducing the DCI overhead and improving the coding efficiency of the channel. And / or, since N TBs are transmitted through T channels in M ​​frequency domain units, at least one shared indication information and N TBs can satisfy the condition that one shared indication information indicates the first transmission parameters of the TBs transmitted through at least one channel in one frequency domain unit, and the number of TBs transmitted in one channel is at least two. That is, one shared indication information indicates the first transmission parameters of at least two TBs. It can be understood that one shared indication information can indicate the first transmission parameters of a large number of TBs, rather than as in the related art, where one shared indication information indicates the transmission parameters of one TB. Therefore, the number of bits of the DCI payload can be reduced, thereby reducing the DCI overhead and improving the coding efficiency of the channel. And / or, since in the case of N TBs being transmitted through T channels in M ​​frequency domain units, at least one shared indication information and N TBs can satisfy the condition that a shared indication information indicates the first transmission parameters of all channels of TBs in at least some of the M frequency domain units. It can be understood that a shared indication information can indicate the first transmission parameters of a large number of TBs, rather than, as is the case in related technologies, a shared indication information indicating the transmission parameters of one TB. Therefore, the number of bits of the DCI payload can be reduced, thereby reducing the DCI overhead and improving the coding efficiency of the channel.

[0186] Case 4: A shared indication information indicates the first transmission parameters of a TB transmitted on a channel, and a shared indication information indicates the first transmission parameters of a TB transmitted on at least one channel of a frequency domain unit.

[0187] In this case, one of the shared indications in a portion of the shared indications indicates the first transmission parameter of a TB transmitted on a channel, and another of the shared indications indicates the first transmission parameter of a TB transmitted on at least one channel of a frequency domain unit.

[0188] It should be noted that, for the description of one shared indication information indicating the first transmission parameter of a TB transmitted on a channel, and another shared indication information indicating the first transmission parameter of a TB transmitted on at least one channel of a frequency domain unit, the specific descriptions in Case 1 and Case 2 above can be referred to, and will not be repeated here in the embodiments of this application.

[0189] In some examples, where the terminal is configured with spatial and temporal bindings for HARQ feedback, one of the shared indications in the other part of the shared indication information indicates the first transmission parameter of the TB for at least one channel transmission of a frequency domain unit.

[0190] Case 5: A shared indication information indicates the first transmission parameters of a TB transmitted on a channel, and a shared indication information indicates the first transmission parameters of a TB transmitted on all channels in at least some of the M frequency domain units.

[0191] In this case, one of the shared indications in at least one portion of the shared indications indicates the first transmission parameter of a TB transmitted on a channel, and one of the shared indications in another portion of the shared indications indicates the first transmission parameter of a TB transmitted by a frequency domain unit in a frequency domain unit group.

[0192] It should be noted that the description of one shared indication information indicating the first transmission parameter of the TB transmitted on a channel, and the description of one shared indication information indicating the first transmission parameter of the TB transmitted by a frequency domain unit in a frequency domain unit group, can be referred to the specific descriptions in Case 1 and Case 3 above. The embodiments of this application will not be repeated here.

[0193] In some examples, when the terminal is configured with HARQ feedback spatial binding, one of the shared indication messages in the other part of the shared indication message above indicates the first transmission parameter of the TB transmitted by the frequency domain unit in a frequency domain unit group.

[0194] Case 6: A shared indication information indicates the first transmission parameters of the TB transmitted by at least one channel of a frequency domain element, and a shared indication information indicates the first transmission parameters of the TB transmitted by all channels of at least some of the M frequency domain elements.

[0195] It should be noted that the description of a shared indication information indicating the first transmission parameters of TB transmitted by at least one channel of a frequency domain unit, and the description of a shared indication information indicating the first transmission parameters of TB transmitted by all channels of at least some of the M frequency domain units, can be referred to the specific descriptions in Case 2 and Case 3 above, and will not be repeated here in the embodiments of this application.

[0196] Example 2: At least one shared indication information and N TBs satisfy a first transmission parameter and a second transmission parameter in at least one transmission parameter of at least one TB among the N TBs.

[0197] In some embodiments of this application, in the case where a shared indication information indicates a first transmission parameter and a second transmission parameter among at least one transmission parameter of at least one of N TBs, the first transmission parameter is also used to indicate the second transmission parameter.

[0198] In some embodiments of this application, the first information field is an NDI field, the first transmission parameter is used to indicate new transmission or retransmission, and the second transmission parameter is used to indicate the RV version. The second transmission parameter satisfies at least one of the following:

[0199] When the first transmission parameter indicates a new transmission, the second transmission parameter indicates that the version of RV is the first predefined version;

[0200] If the first transmission parameter indicates a retransmission, the second transmission parameter indicates that the version of RV is the second predefined version;

[0201] When the first transmission parameter indicates a new transmission, the second transmission parameter indicates that the version of RV is the i-th predefined version among at least two predefined versions ordered in a predefined order;

[0202] When the first transmission parameter indicates a retransmission, the second transmission parameter indicates that the version of RV is the (i+1)th predefined version among at least two predefined versions ordered in a predefined order;

[0203] When the first transmission parameter indicates retransmission and the number of retransmissions is j, the second transmission parameter indicates that the version of RV is the (i+j)th predefined version among at least two predefined versions ordered in a predefined order.

[0204] In the embodiments of this application, i and j are both positive integers.

[0205] In some embodiments of this application, the first transmission parameter mentioned above, which is used to indicate whether a new transmission or a retransmission is made, can be understood as: the first transmission parameter is used to indicate whether the data carried by the corresponding TB is new transmission data or retransmission data.

[0206] In some embodiments of this application, the first predefined version can be RV0. Of course, the first predefined version can also be other versions, and this application does not limit this.

[0207] In some embodiments of this application, the aforementioned second predefined version can be RV3. Of course, the second predefined version can also be other versions, and this application does not limit this.

[0208] In some embodiments of this application, when the first transmission parameter indicates a new transmission, the second transmission parameter indicates that the version of RV is the i-th predefined version among at least two predefined versions ordered in a predefined order; when the first transmission parameter indicates a retransmission, the second transmission parameter indicates that the version of RV is the (i+1)-th predefined version among at least two predefined versions ordered in a predefined order; and when the first transmission parameter indicates a retransmission and the number of retransmissions is j, the second transmission parameter indicates that the version of RV is the (i+j)-th predefined version among at least two predefined versions ordered in a predefined order. Assuming that the at least two predefined versions are defined as RV0, RV3, RV2, and RV1 respectively, when the first transmission parameter indicates an initial transmission, the second transmission parameter indicates that the version of RV is the (i+j)-th predefined version among at least two predefined versions ordered in a predefined order. The first predefined version, RV0, is the i-th predefined version among the two predefined versions. When the first transmission parameter indicates retransmission and the retransmission count is 1, the second transmission parameter indicates that the version of RV is the (i+j)-th predefined version among the at least two predefined versions ordered in the predefined order, i.e., the second predefined version, RV3. When the first transmission parameter indicates retransmission and the retransmission count is 2, the second transmission parameter indicates that the version of RV is the (i+j)-th predefined version among the at least two predefined versions ordered in the predefined order, i.e., the third predefined version, RV2. When the first transmission parameter indicates retransmission and the retransmission count is 3, the second transmission parameter indicates that the version of RV is the (i+j)-th predefined version among the at least two predefined versions ordered in the predefined order, i.e., the fourth predefined version, RV1.

[0209] Thus, since the embodiments of this application specify the specific conditions that the second transmission parameter must meet when the first information field is an NDI field and the first transmission parameter is used to indicate new transmission or retransmission and the second transmission parameter is used to indicate the version of RV, the terminal and network-side device can accurately determine the second transmission parameter based on the first transmission parameter according to the specific conditions, without having to indicate the second transmission parameter through an information field in the DCI, thereby reducing the number of bits in the DCI payload and thus reducing the overhead of the DCI.

[0210] In some embodiments of this application, the first information field is an RV field, the first transmission parameter is used to indicate the version of the RV, and the second transmission parameter is used to indicate new transmission or retransmission. When the first transmission parameter indicates that the RV version is a third predefined version, the second transmission parameter indicates new transmission; when the first transmission parameter indicates that the RV version is a fourth predefined version, the second transmission parameter indicates retransmission.

[0211] In some embodiments of this application, the aforementioned third predefined version can be RV0. Of course, the third predefined version can also be other versions, and this application does not limit this. The aforementioned fourth predefined version can be other versions besides RV0. Of course, the fourth predefined version can also be other versions besides the third predefined version, and this application does not limit this.

[0212] Thus, since the embodiments of this application specify the specific conditions that the second transmission parameter must meet when the first information field is the RV field and the first transmission parameter is used to indicate the RV version and the second transmission parameter is used to indicate new transmission or retransmission, the terminal and network-side device can accurately determine the second transmission parameter based on the first transmission parameter according to the specific conditions, without having to indicate the second transmission parameter through an information field in the DCI, thereby reducing the number of bits in the DCI payload and thus reducing the overhead of the DCI.

[0213] In summary, when N TBs are transmitted through T channels with M frequency domain units, at least one shared indication information and N TBs can satisfy the condition that one shared indication information indicates the first and second transmission parameters of at least one transmission parameter of at least one TB among the N TBs. That is, one shared indication information can indicate a larger number of transmission parameters of TBs, instead of the transmission parameters of one TB as is the case in related technologies. Therefore, the number of bits in the information field of DCI can be reduced, thereby reducing the overhead of DCI and improving the coding efficiency of the channel.

[0214] Example 3: At least one shared indication information and N TBs satisfy the condition that a shared indication information indicates a first transmission parameter in at least one transmission parameter of at least one TB among the N TBs, and a second transmission parameter in at least one transmission parameter of at least one TB is determined by a third transmission parameter.

[0215] In some embodiments of this application, the third transmission parameter can be the kth transmission parameter of at least one TB, where k is a positive integer.

[0216] In some embodiments of this application, the first information field is an NDI field or an RV field; the third transmission parameter is the initial transmission parameter associated with N TBs.

[0217] It is understandable that k is 1 in this example.

[0218] Thus, since the third transmission parameter can be the initial transmission parameter associated with N TB, it means that there is no need to use an additional information field in the DCI to indicate the second transmission parameter. Therefore, the number of bits in the information field of the DCI can be reduced, thereby reducing the overhead of the DCI and improving the coding efficiency of the channel.

[0219] In summary, when N TBs are transmitted through T channels with M frequency domain units, at least one shared indication information and the N TBs can satisfy the condition that one shared indication information indicates the first transmission parameter of at least one transmission parameter of at least one TB among the N TBs, and the second transmission parameter of at least one transmission parameter of at least one TB is determined by the third transmission parameter. That is to say, the second transmission parameter of the N TBs does not need to be indicated by DCI, instead of each transmission parameter corresponding to a TB needing to be indicated by DCI as is the case in related technologies. Therefore, the number of bits in the information field of DCI can be reduced, thereby reducing the overhead of DCI and improving the coding efficiency of the channel.

[0220] Example 4: At least two of the following conditions are satisfied between at least one shared indication information and N TBs: a shared indication information indicates a first transmission parameter among at least two transmission parameters of at least two of the N TBs, and a shared indication information indicates a first transmission parameter and a second transmission parameter among at least one transmission parameter of at least one of the N TBs, and a shared indication information indicates a first transmission parameter among at least one transmission parameter of at least one of the N TBs, and a second transmission parameter among at least one transmission parameter of at least one TB is determined by a third transmission parameter.

[0221] In some embodiments of this application, it is assumed that at least one shared indication information and N TBs satisfy the following: one shared indication information indicates a first transmission parameter among at least two transmission parameters of at least two of the N TBs, and one shared indication information indicates a first transmission parameter and a second transmission parameter among at least one transmission parameter of at least one of the N TBs, and the second transmission parameter of at least one TB is determined by a third transmission parameter; the first information field may include an NDI field, an RV field, and an MCS field. Specifically, for the shared indication information in the NDI field and the N TBs, one shared indication information may indicate the first transmission parameter of at least two of the N TBs; for the shared indication information in the RV field and the N TBs, one shared indication information may indicate the first transmission parameter and a second transmission parameter of at least one of the N TBs; for the shared indication information in the MCS field and the N TBs, one shared indication information may indicate the first transmission parameter of at least one of the N TBs, and the second transmission parameter of at least one TB is determined by a third transmission parameter.

[0222] Of course, other conditions can also be satisfied between the shared indication information of the NDI domain and the N TBs, other conditions can also be satisfied between the shared indication information of the RV domain and the N TBs, and other conditions can also be satisfied between the shared indication information of the MCS domain and the N TBs. These will not be exhaustively listed in the embodiments of this application.

[0223] Step 102: The terminal transmits each TB using at least one transmission parameter per TB based on the DCI and the at least one shared indication information.

[0224] In some embodiments of this application, the terminal may first determine at least one transmission parameter (e.g., a first transmission parameter and a second transmission parameter) for each TB based on at least one shared indication information, and then, based on DCI, transmit or receive the N TBs on T channels in M ​​frequency domain units using the first and second transmission parameters for each TB. The M frequency domain units and T channels may be indicated by DCI.

[0225] In some examples, the terminal can transmit the N TBs on T channels in M ​​frequency domain units, based on DCI, using the first and second transmission parameters for each TB.

[0226] In other examples, the terminal can receive the N TBs on T channels in M ​​frequency domain units, based on DCI and using the first and second transmission parameters for each TB.

[0227] In some examples, the terminal can transmit a portion of the TB on a portion of channels in a portion of a frequency domain unit based on DCI, using a first transmission parameter and a second transmission parameter of a portion of the TB, and transmit the other portion of the TB on another portion of channels in another portion of a frequency domain unit using the first transmission parameter and the second transmission parameter of another portion of the TB.

[0228] This application provides an information transmission method in which a terminal can receive a Data Interchange Component (DCI) from a network-side device. The DCI is used to schedule N Data Transfer Units (TBs). The first information field of the DCI carries at least one shared indication information, which is used to determine at least one transmission parameter for each TB. N is a positive integer greater than or equal to 2. Based on the DCI and the at least one shared indication information, each TB is transmitted using at least one transmission parameter of each TB. The at least one shared indication information and the N TBs satisfy at least one of the following conditions: a shared indication information indicates a first transmission parameter among at least two transmission parameters of the N TBs; a shared indication information indicates a first transmission parameter and a second transmission parameter among at least one transmission parameter of the N TBs; a shared indication information indicates a first transmission parameter among at least one transmission parameter of the N TBs, and the second transmission parameter among the at least one transmission parameter of the at least one TB is determined by a third transmission parameter, which is a transmission parameter associated with the N TBs. Since the first information field of the DCI carries at least one shared indication information and N TBs, satisfying the condition that one shared indication information indicates the first transmission parameters of at least two TBs among the N TBs, instead of the general practice in related technologies where one shared indication information indicates the transmission parameters of one TB, when the number of N TBs scheduled by the DCI is large, the first information field only needs to carry a smaller number of shared indication information, instead of carrying a larger number of N indication information. Therefore, this application can reduce the number of indication information carried by the first information field of the DCI. And / or, since the first information field of the DCI carries at least one shared indication information and N TBs, satisfying the condition that one shared indication information indicates the first and second transmission parameters of at least one TB among the N TBs, that is, one shared indication information can indicate a larger number of transmission parameters for at least one TB, instead of the general practice in related technologies where one shared indication information indicates the transmission parameters of one TB, when the number of N TBs scheduled by the DCI is large, the DCI does not need to indicate the second transmission parameters of each TB among the N TBs through other information fields. Therefore, this application can reduce the number of information fields of the DCI.And / or, since the first information field of the DCI carries at least one shared indication information and N TBs, which can satisfy the condition that one shared indication information indicates the first transmission parameter of at least one TB among the N TBs, and the second transmission parameter of at least one TB is determined by the third transmission parameter, it can be understood that the second transmission parameters of the N TBs do not need to be indicated by the information fields of the DCI, instead of, as in related technologies, one shared indication information indicating the transmission parameter of one TB. Therefore, when the number of N TBs scheduled by the DCI is large, the DCI does not need to indicate the second transmission parameter of each TB among the N TBs through other information fields. It can be understood that this application can reduce the number of information fields of the DCI. Thus, the terminal can accurately transmit each TB using at least one transmission parameter of each TB based on the DCI and the at least one shared indication information. In this way, while ensuring that the terminal can accurately transmit each TB, the overhead of the DCI can be reduced and the coding efficiency of the channel can be improved.

[0229] Furthermore, since this application can reduce the overhead of DCI, it can support a single DCI scheduling more TB / channel, thereby further improving the coding efficiency of the channel.

[0230] Figure 3 shows a flowchart illustrating the information transmission method provided in an embodiment of this application. As shown in Figure 3, the information transmission method provided in an embodiment of this application may include the following step 201.

[0231] Step 201: The network-side device sends DCI to the terminal.

[0232] In this embodiment of the application, the DCI is used to schedule N TBs, and the at least one shared indication information is used to determine at least one transmission parameter for each TB. The first information field of the DCI carries at least one shared indication information, and N is a positive integer greater than or equal to 2.

[0233] In this embodiment of the application, at least one of the following conditions is satisfied between the above-mentioned at least one shared indication information and the N TBs:

[0234] A shared indication information indicates the first transmission parameter in at least one transmission parameter of at least two of the N TBs;

[0235] A shared indication information indicates a first transmission parameter and a second transmission parameter in at least one transmission parameter of at least one TB among N TBs;

[0236] A shared indication information indicates a first transmission parameter in at least one transmission parameter of at least one of the N TBs, and a second transmission parameter in at least one transmission parameter of at least one TB is determined by a third transmission parameter, which is a transmission parameter associated with the N TBs.

[0237] In some embodiments of this application, the above-mentioned N TBs are transmitted through T channels of M frequency domain units, each of the M frequency domain units including at least one channel, where M is a positive integer less than N and T is a positive integer less than N and greater than or equal to M.

[0238] In this embodiment of the application, the aforementioned shared indication information indicates a first transmission parameter among at least two transmission parameters of at least two of the N TBs, including at least one of the following:

[0239] A shared indication information indicates the first transmission parameter of a TB transmitted on a channel;

[0240] A shared indication information indicates the first transmission parameters of the TB transmitted by at least one channel of a frequency domain unit;

[0241] A shared indication information indicates the first transmission parameters of TB for all channel transmissions of at least some of the frequency domain units in M ​​frequency domain units.

[0242] In some embodiments of this application, the aforementioned shared indication information indicates the first transmission parameters of a TB transmitted on a channel, including any of the following:

[0243] When the first frequency domain unit to which the first channel corresponding to the first shared indication information belongs is configured with spatial multiplexing and the first frequency domain unit is configured with dual codewords, the first shared indication information indicates the first transmission parameters of the first TB and the second TB transmitted by the first channel.

[0244] When the first frequency domain unit to which the first channel corresponding to the first shared indication information belongs is configured with spatial multiplexing and the first frequency domain unit is not configured with dual codewords, the first shared indication information indicates the first transmission parameters of the first TB transmitted by the first channel.

[0245] If the first frequency domain unit to which the first channel corresponding to the first shared indication information belongs is configured with spatial multiplexing and the first frequency domain unit is configured with dual codewords, and if the first shared indication information also indicates to disable TB, then the first shared indication information indicates the first transmission parameters of the first TB transmitted by the first channel.

[0246] The first shared indication information indicates the first transmission parameters of the first TB transmitted on the first channel, and the first shared indication information and the second information field of the DCI indicate the first transmission parameters of the second TB transmitted on the first channel.

[0247] Thus, since the embodiments of this application specify the conditions that the first shared indication information (i.e. any shared indication information) in the at least one shared indication information must satisfy when a shared indication information indicates the first transmission parameters of a TB transmitted on a channel, the terminal and network-side equipment do not need additional indications. They can determine the relationship between at least one shared indication information and N TBs based on the conditions, thereby reducing indication overhead.

[0248] In some embodiments of this application, the aforementioned at least one shared indication information further includes second shared indication information. The aforementioned shared indication information indicates the first transmission parameters of the TB transmitted by at least one channel of a frequency domain element, including at least one of the following:

[0249] The second shared indication information indicates the first transmission parameters of TB for all channel transmissions in the scheduling of the second frequency domain unit in the M frequency domain units;

[0250] The number of second shared indication information is at least two, and each second shared indication information indicates the first transmission parameter of the TB of channel transmission in one of the at least two channel groups;

[0251] The second shared indication information indicates the first transmission parameters of the TB for channel transmission in the first channel group, and the second information field of the second shared indication information and DCI indicates the first transmission parameters of the TB for channel transmission in other channel groups.

[0252] In this embodiment of the application, the above-mentioned at least two channel groups are channel groups associated with the second frequency domain unit among the M frequency domain units, the above-mentioned first channel group is a channel group among the at least two channel groups, and the above-mentioned other channel groups are channel groups other than the first channel group among the at least two channel groups.

[0253] Thus, since the embodiments of this application specify the conditions that the second shared indication information (i.e. any shared indication information) in the at least one shared indication information must satisfy when a shared indication information indicates the first transmission parameters of at least one channel of a frequency domain unit transmitted, the terminal and network-side equipment do not need additional indication, and can determine the relationship between at least one shared indication information and N TBs based on the conditions. Therefore, the indication overhead can be reduced.

[0254] In some embodiments of this application, the quantity of the second shared indication information described above satisfies any one of the following:

[0255] Determined by the number of at least two channel groups;

[0256] When the terminal is configured to use time-domain binding for hybrid automatic repeat request (HARQ) feedback, the response is determined by the HARQ group configured on the terminal.

[0257] Thus, since the embodiments of this application specify the conditions that the quantity of the second shared indication information must meet, both the terminal and the network-side device can accurately determine the quantity of the second shared indication information without additional indication, thereby reducing indication overhead.

[0258] In some embodiments of this application, the maximum number of channels in each of the at least two channel groups satisfies at least one of the following:

[0259] It is determined by the maximum number of SLIVs corresponding to the frequency domain unit group to which the channels belong in at least two channel groups and the number of groups in at least two channel groups;

[0260] It is determined by the maximum number of SLIVs corresponding to the frequency domain unit to which the channel in each channel group belongs and the number of groups with at least two channel groups;

[0261] It is determined by the actual number of SLIVs corresponding to the frequency domain units to which the channels in each channel group belong and the number of groups of at least two channel groups.

[0262] In this embodiment of the application, the maximum number of SLIVs corresponding to the frequency domain unit group to which the channels in the above at least two channel groups belong is determined by at least one of the following: the time domain resource allocation (TDRA) table corresponding to the DCI, the actual scheduled frequency domain unit indicated by the third information field of the DCI, and the frequency domain unit group table corresponding to the DCI.

[0263] Thus, since the embodiments of this application specify the conditions that the maximum number of channels in each of the at least two channel groups must meet, the terminal and network-side devices can accurately determine the maximum number of channels in each channel group based on these conditions without additional indication, thereby reducing indication overhead.

[0264] In some embodiments of this application, the aforementioned at least one shared indication information further includes third shared indication information. The aforementioned at least one shared indication information indicates the first transmission parameters of the TB transmitted by the M frequency domain units, including at least one of the following:

[0265] The third shared indication information indicates the first transmission parameters of TB transmitted by M frequency domain units;

[0266] The number of third shared indication information is at least two, and each third shared indication information indicates the first transmission parameter of the TB transmitted by the frequency domain unit in one of the at least two frequency domain unit groups;

[0267] The third shared indication information indicates the first transmission parameters of the TB transmitted by the frequency domain units in the first frequency domain unit group, and the third shared indication information and the second information field of the DCI indicate the first transmission parameters of the TB transmitted by the frequency domain units in other frequency domain unit groups.

[0268] In this embodiment of the application, the above-mentioned at least two frequency domain unit groups satisfy any one of the following: a frequency domain unit group obtained by grouping M frequency domain units, or a frequency domain unit group determined by the HARQ group configured by the terminal; the above-mentioned first frequency domain unit group is a frequency domain unit group among the at least two frequency domain unit groups, and the above-mentioned other frequency domain unit groups are frequency domain unit groups other than the first frequency domain unit group among the at least two frequency domain unit groups.

[0269] Thus, since the embodiments of this application specify the conditions that the third shared indication information (i.e. any shared indication information) in the at least one shared indication information must satisfy when a shared indication information indicates the first transmission parameters of at least one channel of a frequency domain unit transmitted by a first transmission parameter of a TB, the terminal and network side devices do not need additional indications and can determine the relationship between at least one shared indication information and N TBs based on the conditions, thereby reducing indication overhead.

[0270] In some embodiments of this application, when at least two frequency domain cell groups are frequency domain cell groups obtained by grouping M frequency domain cells, the at least two frequency domain cell groups are obtained based on at least one of the following grouping methods:

[0271] The frequency range in which a frequency domain unit is located;

[0272] The subcarrier spacing (SCS) corresponding to the frequency domain unit;

[0273] The duplex mode corresponding to the frequency domain unit;

[0274] Does the frequency domain unit belong to the licensed spectrum?

[0275] The relationship between the bandwidth of a frequency domain unit and its bandwidth threshold;

[0276] Index of frequency domain cells;

[0277] The frequency point corresponding to the frequency domain unit.

[0278] Thus, since the embodiments of this application specify the specific parameters on which the grouping is based to obtain at least two frequency domain unit groups, the terminal and network side devices can accurately divide the M frequency domain units into at least two frequency domain unit groups based on the specific parameters without additional instructions, thereby reducing instruction overhead.

[0279] In some embodiments of this application, the number of the aforementioned third shared indication information is determined by the number of at least two frequency domain unit groups.

[0280] Thus, since the embodiments of this application specify that the number of third shared indication information is determined by the number of at least two frequency domain unit groups, the terminal can accurately determine the number of third shared indication information based on the number of the at least two frequency domain unit groups.

[0281] In some embodiments of this application, the maximum number of frequency domain units in each of the above-mentioned at least two frequency domain unit groups satisfies at least one of the following:

[0282] The number of frequency domain units actually scheduled is determined by the third information domain of the DCI;

[0283] The number of frequency domain units is determined by the maximum number of frequency domain units scheduled by DCI.

[0284] Thus, since the embodiments of this application specify the specific conditions that the maximum number of frequency domain units in each frequency domain unit group must meet, the terminal and network-side devices can accurately determine the maximum number of frequency domain units in each frequency domain unit group based on these specific conditions without additional instructions, thereby reducing instruction overhead.

[0285] In summary, when N TBs are transmitted through T channels with M frequency domain units, at least one shared indication information and N TBs can satisfy the condition that one shared indication information indicates the first transmission parameters of one TB transmitted through one channel, and the number of TBs transmitted through one channel is at least two. That is, one shared indication information indicates the first transmission parameters of at least two TBs. It can be understood that one shared indication information can indicate the first transmission parameters of a large number of TBs, rather than, as is the case in related technologies, one shared indication information indicates the transmission parameters of one TB. Therefore, the number of bits in the DCI payload can be reduced, thereby reducing the DCI overhead and improving the coding efficiency of the channel. And / or, since N TBs are transmitted through T channels in M ​​frequency domain units, at least one shared indication information and N TBs can satisfy the condition that one shared indication information indicates the first transmission parameters of the TBs transmitted through at least one channel in one frequency domain unit, and the number of TBs transmitted in one channel is at least two. That is, one shared indication information indicates the first transmission parameters of at least two TBs. It can be understood that one shared indication information can indicate the first transmission parameters of a large number of TBs, rather than as in the related art, where one shared indication information indicates the transmission parameters of one TB. Therefore, the number of bits of the DCI payload can be reduced, thereby reducing the DCI overhead and improving the coding efficiency of the channel. And / or, since in the case of N TBs being transmitted through T channels of M frequency domain units, at least one shared indication information and the N TBs can satisfy the condition that at least one shared indication information indicates the first transmission parameters of the TBs transmitted through the M frequency domain units, it can be understood that one shared indication information can indicate the first transmission parameters of a larger number of TBs, rather than, as is the case in related technologies, one shared indication information indicates the transmission parameters of one TB. Therefore, the number of bits of the DCI payload can be reduced, thereby reducing the DCI overhead and improving the coding efficiency of the channel.

[0286] In some embodiments of this application, in the case where a shared indication information indicates a first transmission parameter and a second transmission parameter among at least one transmission parameter of at least one of N TBs, the first transmission parameter is also used to indicate the second transmission parameter.

[0287] Thus, it can be seen that when N TBs are transmitted through T channels with M frequency domain units, at least one shared indication information and N TBs can satisfy the condition that one shared indication information indicates the first and second transmission parameters of at least one TB among the N TBs. That is, one shared indication information can indicate a larger number of transmission parameters of TBs, instead of the transmission parameters of one TB as in related technologies. Therefore, the number of bits in the information field of DCI can be reduced, thereby reducing the overhead of DCI and improving the coding efficiency of the channel.

[0288] In some embodiments of this application, the first information field is an NDI field, the first transmission parameter is used to indicate new transmission or retransmission, and the second transmission parameter is used to indicate the RV version. The second transmission parameter satisfies at least one of the following:

[0289] When the first transmission parameter indicates a new transmission, the second transmission parameter indicates that the version of RV is the first predefined version;

[0290] If the first transmission parameter indicates a retransmission, the second transmission parameter indicates that the version of RV is the second predefined version;

[0291] When the first transmission parameter indicates a new transmission, the second transmission parameter indicates that the version of RV is the i-th predefined version among at least two predefined versions ordered in a predefined order;

[0292] When the first transmission parameter indicates a retransmission, the second transmission parameter indicates that the version of RV is the (i+1)th predefined version among at least two predefined versions ordered in a predefined order;

[0293] When the first transmission parameter indicates retransmission and the number of retransmissions is j, the second transmission parameter indicates that the version of RV is the (i+j)th predefined version among at least two predefined versions ordered in a predefined order.

[0294] In the embodiments of this application, i and j are both positive integers.

[0295] Thus, since the embodiments of this application specify the specific conditions that the second transmission parameter must meet when the first information field is an NDI field and the first transmission parameter is used to indicate new transmission or retransmission and the second transmission parameter is used to indicate the version of RV, the terminal and network-side device can accurately determine the second transmission parameter based on the first transmission parameter according to the specific conditions, without having to indicate the second transmission parameter through an information field in the DCI, thereby reducing the number of bits in the DCI payload and thus reducing the overhead of the DCI.

[0296] In some embodiments of this application, the first information field is an RV field, the first transmission parameter is used to indicate the version of the RV, and the second transmission parameter is used to indicate new transmission or retransmission. When the first transmission parameter indicates that the RV version is a third predefined version, the second transmission parameter indicates new transmission; when the first transmission parameter indicates that the RV version is a fourth predefined version, the second transmission parameter indicates retransmission.

[0297] Thus, since the embodiments of this application specify the specific conditions that the second transmission parameter must meet when the first information field is the RV field and the first transmission parameter is used to indicate the RV version and the second transmission parameter is used to indicate new transmission or retransmission, the terminal and network-side device can accurately determine the second transmission parameter based on the first transmission parameter according to the specific conditions, without having to indicate the second transmission parameter through an information field in the DCI, thereby reducing the number of bits in the DCI payload and thus reducing the overhead of the DCI.

[0298] In some embodiments of this application, the first information field is an NDI field or an RV field; the third transmission parameter is the initial transmission parameter associated with N TBs.

[0299] Thus, since the third transmission parameter can be the initial transmission parameter associated with N TB, it means that there is no need to use an additional information field in the DCI to indicate the second transmission parameter. Therefore, the number of bits in the information field of the DCI can be reduced, thereby reducing the overhead of the DCI and improving the coding efficiency of the channel.

[0300] This application provides an information transmission method in which a network-side device can send a DCI to a terminal. The DCI is used to schedule N TBs. The first information field of the DCI carries at least one shared indication information, which is used to determine at least one transmission parameter of each TB, where N is a positive integer greater than or equal to 2. The at least one shared indication information and the N TBs satisfy at least one of the following conditions: a shared indication information indicates a first transmission parameter among at least two transmission parameters of the N TBs; a shared indication information indicates a first transmission parameter and a second transmission parameter among at least one transmission parameter of the N TBs; a shared indication information indicates a first transmission parameter among at least one transmission parameter of the N TBs, and the second transmission parameter among at least one transmission parameter of the at least one TB is determined by a third transmission parameter, which is a transmission parameter associated with the N TBs. Since the first information field of the DCI carries at least one shared indication information and N TBs, satisfying the condition that one shared indication information indicates the first transmission parameters of at least two TBs among the N TBs, instead of the general practice in related technologies where one shared indication information indicates the transmission parameters of one TB, when the number of N TBs scheduled by the DCI is large, the first information field only needs to carry a smaller number of shared indication information, instead of carrying a larger number of N indication information. Therefore, this application can reduce the number of indication information carried by the first information field of the DCI. And / or, since the first information field of the DCI carries at least one shared indication information and N TBs, satisfying the condition that one shared indication information indicates the first and second transmission parameters of at least one TB among the N TBs, that is, one shared indication information can indicate a larger number of transmission parameters for at least one TB, instead of the general practice in related technologies where one shared indication information indicates the transmission parameters of one TB, when the number of N TBs scheduled by the DCI is large, the DCI does not need to indicate the second transmission parameters of each TB among the N TBs through other information fields. Therefore, this application can reduce the number of information fields of the DCI. And / or, since the first information field of the DCI carries at least one shared indication information and N TBs, which can satisfy the condition that one shared indication information indicates the first transmission parameter of at least one TB among the N TBs, and the second transmission parameter of at least one TB is determined by the third transmission parameter, it can be understood that the second transmission parameter of the N TBs does not need to be indicated by the information field of the DCI, instead of the shared indication information indicating the transmission parameter of one TB as is the case in related technologies. Therefore, when the number of N TBs scheduled by the DCI is large, the DCI does not need to indicate the second transmission parameter of each TB among the N TBs through other information fields. It can be understood that this application can reduce the number of information fields of the DCI.Thus, the terminal can accurately transmit each TB using at least one transmission parameter per TB based on the DCI and the at least one shared indication information. In this way, the overhead of the DCI can be reduced and the coding efficiency of the channel can be improved while ensuring that the terminal can accurately transmit each TB.

[0301] Furthermore, since this application can reduce the overhead of DCI, it can support a single DCI scheduling more TB / channel, thereby further improving the coding efficiency of the channel.

[0302] The information transmission method provided in this application can be executed by an information transmission device. This application uses an information transmission device executing the information transmission method as an example to illustrate the information transmission device provided in this application.

[0303] This application provides an information transmission device. As an example, the information transmission device may be a communication device or a component within a communication device, such as a chip. The communication device may be a terminal, a network-side device, or a server, etc. Exemplarily, the terminal may include, but is not limited to, the type of terminal 11 listed above, and the network-side device may include, but is not limited to, the type of network-side device 12 listed above. This application does not impose specific limitations.

[0304] The information transmission device includes a receiving module, a transmitting module, and a processing module. These modules can be implemented in software or hardware. When implemented in hardware, the processing module can be implemented by a processor. For example, the processor can include general-purpose processors, special-purpose processors, etc., such as central processing units (CPUs), microprocessors, digital signal processors (DSPs), artificial intelligence (AI) processors, graphics processing units (GPUs), application-specific integrated circuits (ASICs), network processors (NPs), field-programmable gate arrays (FPGAs), or other programmable logic devices, gate circuits, transistors, discrete hardware components, etc. The receiving and transmitting modules can be implemented by a communication interface, which can include one or more of the following: transceivers, pins, circuits, buses, radio frequency units, etc.

[0305] Specifically, referring to Figure 4, when the information transmission device is a terminal or a component within a terminal, the information transmission device 300 includes: a receiving module 301, used to receive a DCI from a network-side device, the DCI being used to schedule N TBs, the first information field of the DCI carrying at least one shared indication information, the at least one shared indication information being used to determine at least one transmission parameter for each TB, where N is a positive integer greater than or equal to 2. The receiving module 301 or the sending module 302 is used to transmit each TB based on the DCI and the at least one shared indication information, using at least one transmission parameter for each TB.

[0306] Wherein, the above-mentioned at least one shared indication information and the N TBs satisfy at least one of the following: a shared indication information indicates a first transmission parameter in at least one transmission parameter of at least two TBs among the N TBs; a shared indication information indicates a first transmission parameter and a second transmission parameter in at least one transmission parameter of at least one TB among the N TBs; a shared indication information indicates a first transmission parameter in at least one transmission parameter of at least one TB among the N TBs, and the second transmission parameter in at least one transmission parameter of at least one TB is determined by a third transmission parameter, which is a transmission parameter associated with the N TBs.

[0307] This application provides an information transmission apparatus. Since the first information field of the DCI carries at least one shared indication information and N TBs, the shared indication information can indicate the first transmission parameters of at least two TBs among the N TBs, instead of the shared indication information indicating the transmission parameters of one TB as in related technologies. Therefore, when the number of N TBs scheduled by the DCI is large, the first information field only needs to carry a smaller number of shared indication information, instead of carrying a larger number of N indication information. It can be understood that this application can reduce the number of indication information carried by the first information field of the DCI. And / or, since the first information field of the DCI carries at least one shared indication information and N TBs, the shared indication information can indicate the first and second transmission parameters of at least one TB among the N TBs. That is, one shared indication information can indicate a larger number of transmission parameters for at least one TB, instead of the shared indication information indicating the transmission parameters of one TB as in related technologies. Therefore, when the number of N TBs scheduled by the DCI is large, the DCI does not need to indicate the second transmission parameters of each TB among the N TBs through other information fields. It can be understood that this application can reduce the number of information fields of the DCI. And / or, since the first information field of the DCI carries at least one shared indication information and N TBs, which can satisfy the condition that one shared indication information indicates the first transmission parameter of at least one TB among the N TBs, and the second transmission parameter of at least one TB is determined by the third transmission parameter, it can be understood that the second transmission parameters of the N TBs do not need to be indicated by the information fields of the DCI, instead of, as in related technologies, one shared indication information indicating the transmission parameter of one TB. Therefore, when the number of N TBs scheduled by the DCI is large, the DCI does not need to indicate the second transmission parameter of each TB among the N TBs through other information fields. It can be understood that this application can reduce the number of information fields of the DCI. Thus, the information transmission device can accurately transmit each TB using at least one transmission parameter of each TB based on the DCI and the at least one shared indication information. In this way, while ensuring that the information transmission device can accurately transmit each TB, the overhead of the DCI can be reduced and the coding efficiency of the channel can be improved.

[0348] The radio frequency unit 601 is used to receive a DCI from a network-side device. The DCI is used to schedule N TBs. The first information field of the DCI carries at least one shared indication information. The at least one shared indication information is used to determine at least one transmission parameter for each TB, where N is a positive integer greater than or equal to 2. Based on the DCI and the at least one shared indication information, each TB is transmitted using at least one transmission parameter of each TB.

[0349] Wherein, the above-mentioned at least one shared indication information and the N TBs satisfy at least one of the following: a shared indication information indicates a first transmission parameter in at least one transmission parameter of at least two TBs among the N TBs; a shared indication information indicates a first transmission parameter and a second transmission parameter in at least one transmission parameter of at least one TB among the N TBs; a shared indication information indicates a first transmission parameter in at least one transmission parameter of at least one TB among the N TBs, and the second transmission parameter in at least one transmission parameter of the at least one TB is determined by a third transmission parameter, which is a transmission parameter associated with the N TBs.

[0350] This application provides a terminal where, because the first information field of the DCI carries at least one shared indication information and N TBs, the shared indication information can indicate the first transmission parameters of at least two TBs among the N TBs, instead of the shared indication information indicating the transmission parameters of one TB as in related technologies. Therefore, when the number of N TBs scheduled by the DCI is large, the first information field only needs to carry a smaller number of shared indication information, instead of carrying a larger number of N indication information. It can be understood that this application can reduce the number of indication information carried by the first information field of the DCI. And / or, because the first information field of the DCI carries at least one shared indication information and N TBs, the shared indication information can indicate the first and second transmission parameters of at least one TB among the N TBs. That is, one shared indication information can indicate a larger number of transmission parameters for at least one TB, instead of the shared indication information indicating the transmission parameters of one TB as in related technologies. Therefore, when the number of N TBs scheduled by the DCI is large, the DCI does not need to indicate the second transmission parameters of each TB among the N TBs through other information fields. It can be understood that this application can reduce the number of information fields of the DCI. And / or, since the first information field of the DCI carries at least one shared indication information and N TBs, which can satisfy the condition that one shared indication information indicates the first transmission parameter of at least one TB among the N TBs, and the second transmission parameter of at least one TB is determined by the third transmission parameter, it can be understood that the second transmission parameters of the N TBs do not need to be indicated by the information fields of the DCI, instead of, as in related technologies, one shared indication information indicating the transmission parameter of one TB. Therefore, when the number of N TBs scheduled by the DCI is large, the DCI does not need to indicate the second transmission parameter of each TB among the N TBs through other information fields. It can be understood that this application can reduce the number of information fields of the DCI. Thus, the terminal can accurately transmit each TB using at least one transmission parameter of each TB based on the DCI and the at least one shared indication information. In this way, while ensuring that the terminal can accurately transmit each TB, the overhead of the DCI can be reduced and the coding efficiency of the channel can be improved.

[0358] This application provides a network-side device. Since the first information field of the DCI carries at least one shared indication information and N TBs, the shared indication information can indicate the first transmission parameters of at least two TBs among the N TBs, instead of the shared indication information indicating the transmission parameters of one TB as in related technologies. Therefore, when the number of N TBs scheduled by the DCI is large, the first information field only needs to carry a smaller number of shared indication information, instead of carrying a larger number of N indication information. It can be understood that this application can reduce the number of indication information carried by the first information field of the DCI. And / or, since the first information field of the DCI carries at least one shared indication information and N TBs, the shared indication information can indicate the first and second transmission parameters of at least one TB among the N TBs. That is, one shared indication information can indicate a larger number of transmission parameters for at least one TB, instead of the shared indication information indicating the transmission parameters of one TB as in related technologies. Therefore, when the number of N TBs scheduled by the DCI is large, the DCI does not need to indicate the second transmission parameters of each TB among the N TBs through other information fields. It can be understood that this application can reduce the number of information fields of the DCI. And / or, since the first information field of the DCI carries at least one shared indication information and N TBs, which can satisfy the condition that one shared indication information indicates the first transmission parameter of at least one TB among the N TBs, and the second transmission parameter of at least one TB is determined by the third transmission parameter, it can be understood that the second transmission parameters of the N TBs do not need to be indicated by the information fields of the DCI, instead of, as in related technologies, one shared indication information indicating the transmission parameter of one TB. Therefore, when the number of N TBs scheduled by the DCI is large, the DCI does not need to indicate the second transmission parameter of each TB among the N TBs through other information fields. It can be understood that this application can reduce the number of information fields of the DCI. Thus, the terminal can accurately transmit each TB using at least one transmission parameter of each TB based on the DCI and the at least one shared indication information. In this way, while ensuring that the terminal can accurately transmit each TB, the overhead of the DCI can be reduced and the coding efficiency of the channel can be improved.
