Description

Data transmission method and equipment

Technical Field

The embodiment of the application relates to the field of communication, in particular to a data transmission method and device.

Background

In a communication system, generally, one Control Information (CI) schedules one Transport Block (TB). The data channel may be a physical downlink data channel or a physical uplink data channel.

In order to reduce the overhead of CI transmission and save transmission resources, one CI may be used to schedule multiple data channels or one CI may be used to schedule multiple transport blocks.

When one CI schedules a plurality of transport blocks, the CI needs to indicate the number of the scheduled transport blocks, and also needs to indicate a hybrid automatic retransmission request (HARQ) process index (number) corresponding to each transport block.

In the prior art, when one CI schedules a plurality of transport blocks, the CI needs to indicate the number of the scheduled transport blocks and also needs to indicate the HARQ process index corresponding to each transport block separately, so that the required indication overhead is large.

In the prior art, bit overhead of the CI scheduling transport block is too large, and especially considering high-reliability control channel performance, too much bit overhead needs to consume more transmission resources, and how to reduce the indication overhead of the CI scheduling transport block still remains to be solved.

In order to solve the problem of excessive indication overhead of a DCI scheduling transport block in the prior art, the embodiments of the present application provide the following data transmission method, which is suitable for a scenario in which a control information is scheduled to the transport block. The control information in the embodiment of the present application may specifically be downlink control information. Referring to fig. 2, a schematic view of an interaction flow between a network device and a terminal device according to an embodiment of the present application is shown, where the data transmission method according to the embodiment of the present application mainly includes the following steps:

201. and the second communication equipment determines the number of the transmission blocks scheduled by the control information and determines the HARQ process index corresponding to each transmission block in the transmission blocks scheduled by the control information.

In the embodiment of the application, the control information is generated by the second communication device, and the second communication device issues the control information to the first communication device. For example, the control information may be DCI for subsequent examples. The second communication device first determines the number of Transport Blocks (TBs) used for data transmission. For example, the number of transport blocks determined by the second communication device may be 1, or 2, or 3, or 4. The second communications device also needs to determine a HARQ process (process) index corresponding to each of the transport blocks scheduled by the control information. The HARQ process index refers to a HARQ process index corresponding to the transport block, and may also be referred to as a HARQ process sequence number.

For example, as shown in fig. 3, the control information may schedule 8 transport blocks, which are TB1, TB2, 8230, TB7, and TB8, respectively, where the second communications device may further determine a HARQ process index corresponding to each transport block.

In some embodiments of the present application, the first communication device may operate in coverage enhancement mode a, or coverage enhancement level 0, or coverage enhancement level 1. When the first communication device operates in coverage enhancement mode a, the maximum number of transport blocks scheduled by the control information may be 8.

In order to save the indication overhead of the control information, the first information generated by the second communication device in the embodiment of the present application may be used to indicate one or more of the following information: transport block set information, maximum transport block number information, transport block information, first combination set information. For example, the first information may be used only for indicating transport block set information, the first information may be used only for indicating maximum transport block number information, the first information may be used only for indicating transport block information, and the first information may be used only for indicating first combination set information. Without limitation, the first information may indicate any two information, any three information, or all four information.

Optionally, under the condition that the maximum number of the transport blocks is different in value, the first information indicates that the bit overhead required by the maximum number of the transport blocks is different. For example, as follows, when the maximum number of transport blocks is 2, the first information only needs 1 bit to specifically indicate the number of transport blocks scheduled by the control information, for example, the number of transport blocks scheduled by the control information may be 1 or 2. For another example, when the maximum number of transport blocks is 8, the first information needs 3 bits to specifically indicate the number of transport blocks scheduled by the control information, for example, the number of transport blocks scheduled by the control information may be 1,2,3,4,5,6,7, or 8.

The second communication device may also transmit DCI to the first communication device, the DCI indicating which combination of the first set the DCI is scheduled with 2 bits.

the second communication device sends control information to the first communication device, the control information including the first information.

For example, the second communication device may employ higher layer signaling, which may include the first information, so that the first communication device may receive the higher layer signaling, and may obtain the first information generated by the second communication device by parsing the higher layer signaling. For example, the higher layer signaling may include: RRC signaling. In addition, the second communication device may employ physical layer signaling, and the physical layer signaling may include the first information, so that the first communication device may receive the physical layer signaling, and may obtain the first information generated by the second communication device by parsing the physical layer signaling. For example, the physical layer signaling may include: the aforementioned control information, further, the control information may include first information.

And the second communication equipment sends data to the first communication equipment according to the determined number of the transmission blocks and the determined HARQ process index corresponding to each transmission block. Or 204, the second communication device receives the data sent by the first communication device according to the determined number of the transport blocks and the determined HARQ process index corresponding to each transport block.

For example, in a case that the maximum number of transport blocks is different in value, the first information indicates that the bit overhead required for the maximum number of transport blocks is different. For example, as follows, when the maximum number of transport blocks is 2, the first information only needs 1 bit to specifically indicate the number of transport blocks scheduled by the control information, for example, the number of transport blocks scheduled by the control information may be 1 or 2. For another example, when the maximum number of transport blocks is 4, the first information may specifically indicate the number of transport blocks scheduled by the control information by requiring 2 bits, for example, the number of transport blocks scheduled by the control information may be 1,2,3, or 4.

determining the HARQ process indexes of other transport blocks except the first transport block in the plurality of transport blocks according to the HARQ process index of the first transport block; and/or the presence of a gas in the gas,

each transport block in the plurality of transport blocks corresponds to one HARQ process index, and the plurality of HARQ process indexes corresponding to the plurality of transport blocks are consecutive.

For example, the HARQ process indexes of other transport blocks can be calculated by using a preset calculation method for the HARQ process index of the first transport block, so as to obtain the HARQ process indexes of other transport blocks. For example, the preset calculation manner may include a plurality of calculation rules, which are described in detail in the following embodiments. For each transport block in the multiple transport blocks, one HARQ process index is corresponding to each transport block, that is, each transport block is configured with one HARQ process index, and multiple HARQ process indexes corresponding to the multiple transport blocks are consecutive, and when the first information is used to indicate the HARQ process index of the first transport block, the HARQ process indexes of other transport blocks may be consecutively obtained according to all the HARQ process indexes. For example, the HARQ process index of the first transport block is 1, and if the control information schedules 3 transport blocks in total, the HARQ process indexes of other transport blocks start from the HARQ process index 1, and a continuation rule is used to determine that the HARQ process indexes of the other 3 transport blocks are 2,3,4.

Further, in some embodiments of the present application, HARQ process indexes corresponding to other transport blocks except for the first transport block in the plurality of transport blocks are determined according to the HARQ process index corresponding to the first transport block in an ascending order; alternatively, the first and second liquid crystal display panels may be,

the value Rn of the HARQ process index of the nth transport block of the plurality of transport blocks satisfies the following relationship:

Rn＝{R1+n-1}mod N；

wherein, R1 is a value of the HARQ process index of the first transport block, N is a positive integer, mod represents a modulo operation, and N is the maximum number of HARQ processes supported by the control information.

The HARQ process indexes corresponding to other transport blocks except the first transport block in the multiple transport blocks may also be determined according to the HARQ process index corresponding to the first transport block in a sequentially decreasing order, which is not limited herein. In addition, in this embodiment of the present application, the HARQ process index corresponding to each transport block in the multiple transport blocks may be obtained through the modulo arithmetic formula. In an actual application scenario, the acquisition mode of the HARQ process index corresponding to each transport block may be determined in combination with a specific scenario.

In some embodiments of the present application, the first information comprises a first field comprising 1 bit for indicating transport block set information;

when the bit state of the first field is 0, the control information is used for scheduling one transport block and also comprises a second field which indicates the HARQ process index of one transport block; alternatively, the first and second electrodes may be,

when the bit state of the first field is 1, the control information is used for scheduling a plurality of transport blocks, and the control information further includes a third field indicating the number M of transport blocks scheduled by the control information and indicating the HARQ process index corresponding to the first transport block among the M transport blocks.

Wherein the first field contains 1 bit for indicating transport block set information. The bit state of the first field may be 0 or 1. And when the bit state of the first field is 0, indicating that the control information is used for scheduling one transport block, wherein the control information also comprises a second field indicating the HARQ process index of the one transport block. When the bit state of the first field is 1, the control information is indicated to be used for scheduling of multiple transport blocks, and the control information may further include a third field, or the first information includes a third field, where the third field indicates the number of transport blocks scheduled by the control information and indicates the HARQ process index corresponding to the first transport block, or the third field is used to determine the HARQ process indexes of all transport blocks scheduled by the control information. By the above manner, the bit overhead of the control information can be reduced.

For another example, when the bit state of the first field is 1, the control information is indicated to be used for scheduling multiple transport blocks, the first information is higher layer signaling, and the first information may include a third field, where the third field indicates the number of transport blocks scheduled by the control information and indicates the HARQ process index corresponding to the first transport block, or the third field is used to determine the HARQ process indexes of all transport blocks scheduled by the control information. By the above manner, the bit overhead of the control information can be reduced.

Without limitation, in some embodiments of the present application, the second communications device may indicate that the HARQ process index corresponding to the first transport block of the multiple transport blocks may be implemented differently. For example, an implementation manner is implementation manner 1, that is, the second communication device indicates only the HARQ process index corresponding to the first transport block in the multiple transport blocks, and the HARQ process indexes corresponding to other transport blocks (non-first transport blocks) in the multiple transport blocks are determined according to the HARQ process index corresponding to the first transport block according to the sequentially increasing order or the modulo operation formula. For example, another embodiment is embodiment 2, that is, HARQ process indexes corresponding to all transport blocks (including the first transport block) in the plurality of transport blocks are indicated for the second communication device. The corresponding HARQ process indexes in the multiple transport blocks satisfy a sequentially increasing order or satisfy a modulo arithmetic formula. In this case, embodiment 2 is only a modification of embodiment 1. In the embodiment of the present application, embodiment 1 and embodiment 2 are equivalent or equivalent, and are both specific embodiments in which the second communication device indicates the HARQ process index corresponding to the first transport block in the multiple transport blocks.

In some embodiments of the present application, the control information is used for scheduling a plurality of transport blocks, and the control information further includes a third field, where the third field indicates the number M of transport blocks scheduled by the control information and indicates a HARQ process index corresponding to a first transport block of the M transport blocks. In this implementation scenario, further, in this embodiment of the application, for different numbers of transport blocks scheduled by the control information, the HARQ process index of the first transport block may also have multiple value-taking situations, which is described in detail below.

Where the control information is used for scheduling of 5 transport blocks, for example, the first information indicates the HARQ process index of the first transport block from within {0,1,2,3 }. For example, the HARQ process index of the first transport block may be 0, or 1, or 2, or 3. When the control information is used for scheduling of 6 or 2 transport blocks, for example, the first information indicates the HARQ process index of the first transport block within the value set 0,1, 2. For example, the HARQ process index of the first transport block may be 0 or 1, and the HARQ process index of the first transport block may be 0 or 2. When the control information is used for scheduling of 7 or 3 transport blocks, for example, the first information indicates the HARQ process index of the first transport block in the value set {0,1 }. For example, the HARQ process index of the first transport block may be 0, or 1. When the control information is used for

scheduling

For example, when the control information schedules 4 transport blocks, the HARQ process index of all transport blocks scheduled by the control information may be 0,1,2,3. For details, see the example content shown in table 2 in the following embodiment, the bit overhead of the control information may be reduced by the above manner.

m =8, the first information indicates that the HARQ process index value of the first transport block is 0, and the plurality of HARQ process indexes corresponding to the plurality of transport blocks are consecutive.

In the embodiment of the present application, the second communication device may limit the maximum number of transport blocks scheduled by the control information, so that the control information only needs to indicate a specific maximum number of transport blocks from the set of values {2,4,6,8}, but does not need to indicate all the numbers of transport blocks, and thus the indication overhead of the control information may be reduced. For details, see the example content shown in table 4 in the following embodiments, the bit overhead of the control information may be reduced by the above manner.

In some embodiments of the present application, the first information comprises a first field comprising 1 bit;

The control information further includes a fourth field, or when the first information is a high layer signaling, the first information includes the fourth field, and the fourth field indicates the HARQ process index of the first transport block in the plurality of transport blocks scheduled within the first transport block number range, or the fourth field indicates the HARQ process index of the first transport block in the plurality of transport blocks scheduled within the second transport block number range. Through the above manner, only the HARQ process index of the first transport block needs to be indicated, and no indication is needed for other HARQ process indexes scheduled by the control information, which is detailed in the example content shown in table 7a in the subsequent embodiments.

the number range of the first transmission block is {1,2,3,4}, when the control information schedules A transmission blocks, the first information indicates the HARQ process index of the first transmission block in a value set {0,1}, and A is a value in the value set {1,3 }. When the control information schedules 2 transport blocks, the first information indicates the HARQ process index of the first transport block in the value set {0,1,2 }. When the control information schedules 4 transport blocks, the HARQ process index value of the first transport block indicated by the first information is 0. Alternatively, the first and second electrodes may be,

When the control information schedules 4 transport blocks, the first information indicates that the HARQ process index value of the first transport block is 0.

Wherein, the first range of the number of the transport blocks is {1,2,3,4} indicates that the number of the transport blocks scheduled by the control information can be only one value of {1,2,3,4 }. The first information may indicate that the HARQ process index of the first transport block is 0, or 1. In addition, when the number of the transport blocks scheduled by the control information is specifically 1 or 2 or 3 or 4, the first information indicates that the HARQ process index of the first transport block may be flexibly configured according to the above example, and by the above manner, only the HARQ process index of the first transport block needs to be indicated, and no indication is needed for other HARQ process indexes scheduled by the control information, which is described in detail in table 7a in the subsequent embodiments.

Further, in some embodiments of the present application, the number of the second transport blocks ranges from {5,6,7,8}, the control information schedules K transport blocks, the first information indicates the HARQ process index of the first transport block within the value set {0,1}, K is a value in the value set {5,6,7,8 }; alternatively, the first and second liquid crystal display panels may be,

Wherein, the range of the number of the first transport block is 5,6,7,8, which means that the number of the transport blocks scheduled by the control information can only be one value of 5,6,7,8, and the first information may indicate that the HARQ process index of the first transport block is 0 or 1. In addition, when the number of the transport blocks scheduled by the control information is specifically 5 or 6 or 7 or 8, the first information indicates that the HARQ process index of the first transport block may be flexibly configured according to the above example, and by the above manner, only the HARQ process index of the first transport block needs to be indicated, and no indication is needed for other HARQ process indexes scheduled by the control information, which is described in detail in table 7b in the subsequent embodiments.

The transport block information may be used to indicate the number of transport blocks scheduled by the control information, for example, the transport block information includes 3 bits. The HARQ process index of the first transport block in the one or more transport blocks scheduled by the control information is 0, and the plurality of HARQ process indexes corresponding to the plurality of transport blocks are consecutive, at this time, no indication is needed for the HARQ process index of each transport block, because the HARQ process index of the first transport block is fixed to 0, at this time, the HARQ process indexes of other transport blocks can be sequentially obtained. For details, see the example content shown in table 5 in the subsequent embodiment, the bit overhead of the control information may be reduced by the above manner.

In some embodiments of the present application, the first information comprises a first field, the first field comprising 4 bits, the first field indicating one or more transport blocks scheduled by the control information;

when a =1,b =3,c =6,d =7,e =2,f =5,g =4, as detailed in the example shown in table 6 in the subsequent embodiment, the bit overhead of the control information can be reduced in the above manner. When a =1,b =3,c =5,d =7,e =2,f =6,g =4; alternatively, when a =2,b =3,c =6,d =7,e =1,f =2,g =4, the contents of the example shown in table 6 in the subsequent embodiment can be obtained similarly.

In some embodiments of the present application, the higher layer signaling is radio resource control signaling, the radio resource control signaling including the first information;

when the first information includes the maximum number of transport blocks information and/or the first combination information, the control information indicates the number of transport blocks scheduled by the control information and indicates the HARQ process index of the first transport block in the transport blocks scheduled by the control information.

In further embodiments of the present application, when the first information includes maximum transport block number information and/or first combination information, the control information indicates the number of transport blocks scheduled by the control information and indicates HARQ process indexes of all transport blocks scheduled by the control information.

The first information comprises transmission block information, and if the transmission block information only indicates the HARQ process index of the first transmission block in the transmission blocks scheduled by the control information, the control information indicates the number of the transmission blocks scheduled by the control information, so that the HARQ process index of the first transmission block and the number of the transmission blocks scheduled by the control information can be determined through the transmission block information and the control information. In another implementation scenario, the first information is a high layer signaling, and when the first information includes maximum transport block number information and/or first combination information, the control information may indicate the number of transport blocks scheduled by the control information and indicate an HARQ process index of a first transport block in the transport blocks scheduled by the control information, or the control information indicates HARQ process indexes of all transport blocks scheduled by the control information, and for whether the control information indicates an HARQ process index of the first transport block or HARQ process indexes of all transport blocks, the implementation scenario is not limited herein.

Further, in some embodiments of the application, when the first information includes transport block information, the method further includes: the first communication device receives HARQ process index set information sent by the second communication device, wherein the HARQ process index set information indicates at least one HARQ process index set.

The second communication device may further send HARQ process index set information to the first communication device, so that the first communication device may determine at least one HARQ process index set according to the HARQ process index set information. The second communication device may send HARQ process index set information to the first communication device, so that the second communication device further sends control information to the first communication device, where the control information indicates the HARQ index and/or indicates the number of transport blocks in the HARQ process index set determined by the second communication device, and therefore, the indication overhead of the control information may be reduced.

In some embodiments of the present application, the first information indicates maximum transport block number information, and indicates a maximum transport block number within a set of values {1,2,4,8 };

the maximum transmission block number indicated by the first information is 1, and the HARQ process index of the first transmission block is indicated in a value set {0,1,2,3,4,5,6,7} by using 3 bits in the control information; or the like, or, alternatively,

the maximum transmission block number indicated by the first information is taken as 2, 1 bit in the control information indicates the transmission block number scheduled by the control information, and 2 bits in the control information indicate the HARQ process index of the first transmission block in a value set {0,2,4,6 }; or the like, or a combination thereof,

the maximum transmission block number indicated by the first information is 4, 2 bits are used for indicating the transmission block number scheduled by the control information in the control information, and 1 bit is used for indicating the HARQ process index of the first transmission block in a value set {0,4} in the control information; or the like, or, alternatively,

the maximum transport block number indicated by the first information is 8, the number of transport blocks scheduled by the control information is indicated by 3 bits in the control information, and the HARQ process index of the first transport block in the multiple transport blocks scheduled by the control information is 0.

In the embodiment of the present application, the second communication device may limit the maximum number of transport blocks scheduled by the control information, so that the control information only needs to indicate a specific maximum number of transport blocks from the set of values {1,2,4,8}, and does not need to indicate all the number of transport blocks, and the control only needs to occupy 3 bits in total to indicate the number of transport blocks scheduled by the control information and the first HARQ process index, which is described in table 8 in the following embodiment.

In some embodiments of the present application, all transport blocks scheduled by the control information are all initially transmitted transport blocks, or all transport blocks scheduled by the control information are all retransmitted transport blocks.

Wherein, all the initially transmitted transmission blocks refer to that the transmission modes of all the transmission blocks scheduled by the control information are initially transmitted, and all the retransmitted transmission blocks refer to that the transmission modes of all the transmission blocks scheduled by the control information are retransmitted. For example, 1 bit may be used in the control information to indicate that all transport blocks are all initially transmitted transport blocks or all retransmitted transport blocks, so that the communication device determines whether all transport blocks adopt all initial transmissions or all retransmissions by analyzing the control information.

As can be seen from the foregoing description of the embodiment, in order to enable the first communication device to obtain the number of transport blocks determined by the second communication device and the HARQ process index corresponding to each transport block, the second communication device may generate a first message, and send the first message to the first communication device, so that the first communication device can obtain the number of transport blocks determined by the second communication device and the HARQ process index corresponding to each transport block according to the received first message. In order to save the indication overhead of the control information, the first information generated by the second communication device in the embodiment of the present application may be used to indicate one or more of the following information: transport block set information, maximum transport block number information, transport block information, first combination set information. In the embodiment of the application, the HARQ process indexes corresponding to the transmission blocks of the downlink information scheduling can be limited, so that the bit overhead of the control information can be optimized, and the transmission performance of the control information is improved.

In order to better understand and implement the above-mentioned solution of the embodiments of the present application, the following description specifically illustrates a corresponding application scenario.

In the embodiment of the present application, a first communication device is taken as a UE, a second communication device is taken as a base station for example, and the foregoing control information is DCI specifically.

In the embodiment of the present application, the flexibility of the HARQ process index is not important enough with respect to the flexibility indicated by the number of TBs, that is, the flexible scheduling of the number of TBs is preferentially ensured in the embodiment of the present application, so that the HARQ process corresponding to each TB scheduled by DCI is limited, DCI bit overhead is optimized, and DCI transmission performance is improved.

The embodiment of the application only needs 3 to 5 bits to indicate the scheduled TB and HARQ process.

In the embodiment of the application, the second communication device sends the first information to the first communication device. The second communication device may be a base station, or a device with transmission capability. The first communication device may be a user equipment, or a device with receiving capabilities. The first information may be included in higher layer (e.g., RRC or medium access control) signaling or physical layer signaling. The definition of the first information is as described above and is not described herein.

Optionally, HARQ process indexes corresponding to different TBs of the multiple TBs scheduled by the DCI are all the same.

Optionally, the first information indicates a HARQ process index of the first TB, and HARQ process indexes corresponding to other TBs are obtained according to the HARQ process index of the first TB.

Optionally, the first information indicates a set of TBs that the DCI can schedule, or a maximum number of TBs that can be scheduled. Optionally, if the first information indicates that the set of TB numbers that the DCI can schedule is the first set of TB numbers.

In the embodiment of the present application, the TB number set information indicates whether DCI is scheduling for a first number of transport blocks or scheduling for a second number of transport blocks. The first information may be information carried in DCI, or may be information that is notified to the user equipment by the base station through a higher layer signaling. The first information may comprise one or more bits or one or more states of a field.

The first amount may be a specific value, may be a set of values, or may be a range of values. The first number may be predefined or base station configured or indicated. For example, the first number is a value configured or indicated by the base station, or the first number is a set of values configured or indicated by the base station, or the first number is a predefined range of values.

The second number may be a specific number, may be a collection of numbers, or may be a range of numbers. The second number may be predefined or base station configured or indicated. For example, the second number is a value configured or indicated by the base station, or the second number is a set of values configured or indicated by the base station, or the second number is a predefined range of values.

For example, the first number is equal to 1, the second number is N, and 1< -N < -M, M is a predetermined integer.

For example, the first number is a set of values, and the first number is {1,2,3,4}, the second number is a set of values, and the second number is {5,6,7,8}.

For example, the size of the first information is 1 bit. When the bit state of the first information is 0, the DCI indicates that the DCI is used for scheduling of only one transport block, and when the bit state of the first information is 1, the DCI indicates that the DCI is usable for scheduling of one and/or more transport blocks.

For example, the first information is a bit state of the first field. The DCI indicates scheduling of the DCI for one transport block when the bit state of the first information is a first state of a first field, and indicates scheduling of the DCI for a plurality of transport blocks when the bit state of the first information is a second state of the first field.

When the first information indicates that the DCI is used for scheduling of a second number of transport blocks, each transport block in the second number of transport blocks corresponds to one HARQ process index. The HARQ process index for different transport blocks may be different. Optionally, HARQ process indexes corresponding to different transport blocks may also be the same.

For example, the second number is a value in the range of 2 to 8. The HARQ process indexes for each transport block of the second number of transport blocks are different, and the second number of HARQ process indexes for the second number of transport blocks are consecutive.

For example, when the first information indicates that DCI is used for scheduling of a second number of transport blocks, an indication that 8 HARQ processes are supported is assumed.

For example, when the second number is 2, the number of HARQ processes corresponding to 2 transport blocks is { n } ₀ ,n ₁ Or the number of HARQ processes corresponding to 2 transport blocks is { n } ₂ ,n ₃ Or the number of HARQ processes corresponding to 2 transport blocks is { n } ₄ ,n ₅ }。

For another example, when the second number is 2, the number of HARQ processes corresponding to 2 transport blocks is { n } ₀ ,n ₁ The number of HARQ processes corresponding to 2 transport blocks is { n }, or ₁ ,n ₂ The number of HARQ processes corresponding to 2 transport blocks is { n }, or ₂ ,n ₃ }。

For example, when the second number is 3, the number of HARQ processes corresponding to 3 transport blocks is { n } ₀ ,n ₁ ,n ₂ Is { n } or the number of HARQ processes corresponding to 3 transport blocks is { n } ₁ ,n ₂ ,n ₃ }。

For example, when the second number is 4, the number of HARQ processes corresponding to 4 transport blocks is { n } ₀ ,n ₁ ,n ₂ ,n ₃ }。

For example, when the second number is 5, the number of HARQ processes corresponding to 5 transport blocks is { n } ₀ ,n ₁ ,n ₂ ,n ₃ ,n ₄ Or the number of HARQ processes corresponding to 5 transport blocks is { n } ₁ ,n ₂ ,n ₃ ,n ₄ ,n ₅ }, or the number of HARQ processes corresponding to 5 transport blocks is

{n ₂ ,n ₃ ,n ₄ ,n ₅ ,n ₆ Or the number of HARQ processes corresponding to 5 transport blocks is { n } ₃ ,n ₄ ,n ₅ ,n ₆ ,n ₇ }。

For example, when the second number is 6, the number of HARQ processes corresponding to 6 transport blocks is { n } ₀ ,n ₁ ,n ₂ ,n ₃ ,n ₄ ,n ₅ The number of HARQ processes corresponding to the transport block is { n }, or 6 transport blocks ₁ ,n ₂ ,n ₃ ,n ₄ ,n ₅ ,n ₆ The number of HARQ processes corresponding to the transport block is { n }, or 6 transport blocks ₂ ,n ₃ ,n ₄ ,n ₅ ,n ₆ ,n ₇ }。

For example, when the second number is 7, the number of HARQ processes corresponding to 7 transport blocks is { n } ₀ ,n ₁ ,n ₂ ,n ₃ ,n ₄ ,n ₅ ,n ₆ H, or the number of HARQ processes corresponding to 7 transport blocks is n ₁ ,n ₂ ,n ₃ ,n ₄ ,n ₅ ,n ₆ ,n ₇ }。

For example, when the second number is 8, the number of HARQ processes corresponding to 8 transport blocks is { n } ₀ ,n ₁ ,n ₂ ,n ₃ ,n ₄ ,n ₅ ,n ₆ ,n ₇ }。

When the first information state is a first bit state, the DCI schedules a TB, and the HARQ process corresponding to the TB is indicated by the base station. Such as 3 bits to indicate the index corresponding to the TB from 8 indexes.

When the first information state is the second bit state, the DCI schedules 2 to 8 TBs. The DCI indicates the number of scheduled TBs and indicates HARQ process indexes corresponding to the respective TBs. As shown in table 1, when the number of TBs is 2 to 8, there are 16 combinations for each TB number and its corresponding HARQ process combination. Therefore, when the first information state is the second bit state, 4 bits can be further used to indicate the number of scheduled TBs of the DCI and HARQ process indexes corresponding to the scheduled TBs.

Table 1: DCI indicates the number of TBs scheduled and the HARQ process index

Table 2 illustrates that when the number of the DCI scheduled TBs is 2 to 8, the number of the DCI scheduled TBs is indicated with 4 bits, and HARQ process indexes corresponding to the scheduled TBs. Alternatively, the DCI only indicates the HARQ process index of the first TB block of the multiple TB blocks (e.g., the third column of table 2). Optionally, the DCI indicates HARQ process indexes of respective TB blocks of the multiple TB blocks (e.g., the fourth column of table 2).

When the DCI only indicates the HARQ process index of the first TB block in the multi-TB blocks, the HARQ process indexes of other TB blocks in the multi-TB blocks indicated by the DCI are obtained by increasing (or decreasing) according to the HARQ process index of the first TB block according to a natural sequence. If the DCI indicates that 3 TB blocks are scheduled, and the HARQ process index of the first TB block is m, the HARQ process index of the second TB block is m +1, and the HARQ process index of the third TB block is m +2.

Similarly, the DCI only indicates the HARQ process index of the first TB block of the multiple TB blocks (e.g., the third column of table 4). Similarly, the DCI indicates the HARQ process index of each of the multiple TB blocks (e.g., the fourth column of table 4).

Table 4: DCI indicates to schedule multiple TBs and HARQ process index corresponding to each TB

Another indication method is illustrated in table 5 below.

When the first information bit state is the first bit state of the first field, the DCI schedules one TB, and the HARQ process corresponding to the TB is fixed (e.g., 0). When the first information bit state is a second bit state of the first field, the DCI schedules a plurality of TBs, and a HARQ process corresponding to a first TB of the plurality of TBs is fixed. And the HARQ process indexes of other TB blocks in the multi-TB block indicated by the DCI are obtained by increasing according to the HARQ process index of the first TB block in a natural order. For example, the HARQ process index corresponding to the first TB is 0.
