Description

Technical Field

[0001] The embodiments of the present application relate to the field of communications, and in particular to an information processing method, a terminal device, and a network device. Background Art

[0002] In a communication system, a downlink control information (DCI) schedules a transport block (TB) or schedules multiple transport blocks. When DCI schedules a TB, DCI also indicates a hybrid automatic retransmission request (HARQ) process number. For example, if the user equipment (UE) supports 8 HARQ processes, the DCI uses 3 bits from 0 to 7 to indicate the HARQ process number used by the TB scheduled by the DCI. When DCI schedules a TB, DCI also indicates whether the data transmission scheduled by the DCI carries a new TB or a retransmission TB.

[0003] In order to reduce the overhead of DCI transmission and save transmission resources, one DCI may be used to schedule multiple TBs. When one DCI schedules multiple transport blocks, the DCI may indicate multiple HARQ process numbers, each of which corresponds to or is associated with the transmission of one transport block.

[0004] In order to further reduce the overhead when a DCI schedules multiple transport blocks, it is necessary to constrain the HARQ process numbers used by multiple transport blocks to be continuous, and it is also necessary to fix the first HARQ process number among the multiple HARQ process numbers. For example, a DCI schedules N transport blocks, and the HARQ process number of the first transport block among the N transport blocks is fixed, such as fixed to 0, then the HARQ process numbers of the remaining N-1 transport blocks among the N transport blocks are 1, 2, ..., N-1.

[0005] In the case where DCI can schedule a maximum of N transport blocks, N bits are required to indicate the new data indicator (NDI) information of each transport block in a bitmap manner, and N bits are required to indicate whether the HARQ process number of each transport block is used in a bitmap manner. Therefore, a total of 2N bits are required to indicate the number of scheduled transport blocks and the NDI information of each transport block. Therefore, there is a problem of excessive overhead when the control channel indicates the number of transport blocks and the NDI information of each transport block. Summary of the invention

[0075] See also Figure 2 As shown, it is a schematic diagram of an interactive process of an information processing method provided in an embodiment of the present application. The subsequent steps 201 to 205 are described from the side of the network device, and the subsequent steps 211 to 215 are described from the side of the terminal device, which mainly includes the following steps:

[0076] 201. The network device determines the number L of transmission blocks TB scheduled by downlink control information, wherein the downlink control information can schedule a maximum of N TBs, N is a positive integer, L is a positive integer, and 1≤L≤N.

[0077] The downlink control information can schedule one or more TBs, for example, the number of TBs scheduled by the downlink control information is represented by the letter L. The downlink control information can schedule a maximum of N TBs, where N is a positive integer, L is a positive integer, and 1≤L≤N, and the specific value of L is not limited here.

[0078] The number L of transport blocks TB scheduled by the downlink control information may also be the number L of hybrid automatic repeat request HARQ processes indicated by the downlink control information, that is, the number of TBs and the number of KARQ processes are in one-to-one correspondence.

[0079] 202. The network device determines the HARQ process numbers of the L TBs.

[0080] In an embodiment of the present application, when the network device determines that the number of TBs scheduled for downlink control information is L, the network device also needs to determine the HARQ process numbers of the L TBs, for example, determine the HARQ process number of each TB in the L TBs. The HARQ process number can also be called a HARQ process index.

[0081] 203. The network device determines L TB of new data indication NDI information.

[0082] In the embodiment of the present application, when the network device determines that the number of TBs scheduled by the downlink control information is L, the network device also needs to determine the NDI information of the L TBs, for example, the network device needs to determine the NDI information of each TB in the L TBs. For example, the NDI information is carried in the downlink control information.

[0083] It should be noted that the NDI information indicates whether the data transmission scheduled by the downlink control information carries a new TB or a retransmitted TB. For example, the NDI information may include feedback information of each TB in L TBs, where the feedback information of the TB can also be called the response information of the TB.

[0084] There is no temporal order between step 202 and step 203. For example, the network device may execute any one of steps 202 and 203 first, or execute steps 202 and 203 simultaneously. There is no limitation here.

[0085] 204. The network device sends downlink control information to the terminal device. The downlink control information can schedule the new transmission TB and the retransmission TB at the same time. The downlink control information includes a first field. The first field includes (N+2) bits b0, b1, ..., b N+1 .

[0086] j consecutive bits b in the first field k , b k+1 , …, b k+j-1 In the example, only one bit is in the state of 1, and the states of the other j-1 bits are all 0, j is a positive integer, and j=N+1-L, k is a predetermined integer, k=0, or k=L+1;

[0087] k = 0, and b in the first field j The bit state of the bit is 1, and L consecutive bits b in the first field j+1 , b j+2 , …, b N+1 Carrying NDI information of L TBs scheduled for downlink control information;

[0088] Or, k = L + 1, and b in the first field L The bit state of the bit is 1, and L consecutive bits b0, b1, ..., b in the first field are L-1 Carrying NDI information of L TBs scheduled by downlink control information.

[0089] In an embodiment of the present application, the downlink control information can schedule both the newly transmitted TB and the retransmitted TB at the same time, where "can" refers to the ability of the network device to schedule different TB types (such as newly transmitted TB and retransmitted TB) through the downlink control information. The downlink control information can schedule both the newly transmitted TB and the retransmitted TB at the same time, but the network device can determine the type of TB actually scheduled in the downlink control information based on the type of TB that needs to be fed back. The downlink control information can schedule both the newly transmitted TB and the retransmitted TB at the same time, and the downlink control information includes a first field, and the first field includes (N+2) bits, and the (N+2) bits are b0, b1, ..., b N+1 , where bh is the h+1th bit in the first field, h is an integer, and 0≤h≤N+1. h The subscript "h" and the b h The position in the first field (h+1th bit) has a mapping relationship.

[0090] In the embodiment of the present application, j consecutive bits b in the first field k , b k+1 , …, b k+j-1 In the state of only 1 bit, the states of the other j-1 bits are all 0, j is a positive integer, and j=N+1-L, k is a predetermined integer, k=0, or k=L+1.

[0091] For j consecutive bits b k , b k+1 , …, b k+j-1 Only one bit in the state is 1, j consecutive bits b k , b k+1 , …, b k+j-1 The states of the remaining j-1 bits in are all 0. The j consecutive bits b are determined according to the actual scenario. k , b k+1 , …, b k+j-1 Which bit in the first field is in the state of 1. It is not limited to that the embodiment of the present application is also applicable to j consecutive bits b in the first field. k , b k+1 , …, b k+j-1 In the embodiment, only one bit is in the state of 0, and the states of the other j-1 bits are all 1. The specific implementation method is similar to the above embodiment and will not be repeated here.

[0092] See also Figure 3a FIG. 1 is a schematic diagram of a composition structure of the first field in the downlink control information provided in an embodiment of the present application. k=0, and b in the first field j The bit state of the bit is 1, and L consecutive bits b in the first field j+1 , b j+2 , …, b N+1 Carrying the NDI information of L TBs scheduled by downlink control information. Figure 3a In the example, follow the principle from left to right to determine which bit’s bit state is 1.

[0093] See also Figure 3b The figure is a schematic diagram of a composition structure of the first field in the downlink control information provided by the embodiment of the present application. k=L+1, and b in the first field L The bit state of the bit is 1, and L consecutive bits b0, b1, ..., b in the first field areL-1 Carrying the NDI information of L TBs scheduled by downlink control information. Figure 3b In the example, follow the principle from right to left to determine which bit's bit state is 1.

[0094] For example, if the value of N is 8, only 10 bits are needed in the embodiment of the present application to support scheduling of any TB number among 8 TBs by one DCI under continuous HARQ processnumber, and the HARQ processnumber and HARQ-ACK response information of each transmission block can be flexibly indicated, thereby improving the scheduling flexibility and saving the indication overhead of DCI.

[0095] In some embodiments of the present application, the information processing method performed by the network device may further include the following steps:

[0096] The network device determines one or more bit states in the first field according to the correspondence between the bit state of the first field and the HARQ process number of the first TB in L, L TBs and the NDI information of each TB in the L TBs, where the first TB is one TB in the L TBs.

[0097] Among them, the network device can pre-configure the correspondence between the bit state of the first field and the HARQ process number of the first TB in L, L TBs and the NDI information of each TB in the L TBs. In the correspondence, the bit state of the first field is configured to correspond to: the HARQ process number of the first TB in L, L TBs and the NDI information of each TB in the L TBs. Therefore, by querying the correspondence between the bit state of the first field and the HARQ process number of the first TB in L, L TBs and the NDI information of each TB in the L TBs, the HARQ process number of the first TB in L, L TBs and the NDI information of each TB in the L TBs can be quickly determined, thereby improving the efficiency of the network device in generating downlink control information.

[0098] In some embodiments of the present application, the L is determined based on the correspondence between the bit state of the first field and the number of TBs L, the HARQ process number of each TB in the L TBs is determined based on the HARQ process number of the first TB, the HARQ process number of the first TB is determined based on the correspondence between the bit state of the first field and the HARQ process number of the first TB, the first TB is one TB in the L TBs, and the feedback information of each TB in the L TBs is determined based on the correspondence between the bit state of the first field and the feedback information of the L TBs.

[0099] Among them, the network device can pre-configure the correspondence between the bit state of the first field and the HARQ process number of the first TB, and configure the HARQ process number of the first TB corresponding to the bit state of the first field in the correspondence, so as to query the correspondence between the bit state of the first field and the HARQ process number of the first TB among L TBs, and the HARQ process number of the first TB among the L TBs can be quickly determined. The HARQ process numbers of all TBs in the L TBs are continuous, so the HARQ process numbers of other TBs are determined through the HARQ process number of the first TB, which is convenient for the network device to improve the efficiency of generating downlink control information.

For example, the first node configures N to the second node through radio resource control signaling, or the first node configures N to the second node through media access control signaling, or the first node configures N to the second node through physical layer signaling. For example, the value set of N is {1,2,4,8}. Or, the value set of N is {2,4,8}. Or, the value set of N is {1,4,8}. Or, the value set of N is {1,2,8}.

[0192] When N is greater than 1, the DCI supports that the multiple TBs scheduled may include new transmission TBs and retransmission TBs. The TBs scheduled by the DCI may also all be new transmission TBs. The TBs scheduled by the DCI may also all be retransmission TBs. The first field in the DCI indicates the HARQ process number of multiple TBs and indicates the response information. For example, when N is greater than 1, the first field contains N+2 bits. For example, the N+2 bits of the first field are b0, b1, ..., b N+1 .

[0193] like Figure 3a As shown, N+1-L bits of the N+2 bits of the first field indicate the HARQ processnumber of the first TB, L bits of the N+2 bits of the first field indicate feedback information in a bitmap manner, and one bit of the N+2 bits of the first field is used to indicate the number of TBs scheduled by DCI (or the number of HARQ processes used by DCI).

[0194] There is a first association relationship between the process numbers of the L HARQ processes. For example, the process numbers of the L HARQ processes satisfy a predefined first association relationship. For example, the first association relationship between the process numbers of the L HARQ processes is: the process numbers of the L HARQ processes are continuous. That is, the process numbers of the L HARQ processes are: k, k+1, k+2,…, k+L-1. For example, the first association relationship between the process numbers of the L HARQ processes is: the process numbers of the L HARQ processes are equally spaced. That is, the process numbers of the L HARQ processes are: k, k+2, k+4,…, k+2L-2. For another example, the first association relationship between the process numbers of the L HARQ processes is: the process numbers of the L HARQ processes are calculated by the formula. For example, the HARQ process number corresponding to the j+1th TB in the L TBs is: mod{(k+j),M}. Here M is the maximum number of HARQ processes that the UE can support. For another example, the association relationship between the process numbers of the L HARQ processes is configured at a high level.

[0195] Please refer to Example 1a: The implementation of the embodiment of the present application is described below from the first node side:

[0196] The first node indicates a DCI scheduled TB number (or a HARQ process number used by the DCI) L. L is a positive integer greater than or equal to 1 and less than or equal to N.

[0197] The first node determines the number of TBs L scheduled by a DCI or the number of HARQ processes used by the DCI, and determines the value of j according to N and L. The first node sets the state of the bj bit in the first field to 1. For example, j=N+1-L.

[0198] The first node indicates the response information of each TB in the L TBs scheduled by the DCI.

[0199] The first node determines the response information of each TB in the L TBs. The first node indicates the response information of each TB in the L TBs scheduled by the DCI in a bitmap manner using L bits. For example, the bit position of the L bits in the first field is b j+1 ,…,b N+1 For example, the b j+1 ,…,b N+1 is L NDI bits. j+1 ,…,b N+1 Each NDI bit in b is associated with each TB in L TBs. j+1 ,…,b N+1 is L ACK / NACK indication bits. j+1 ,…,b N+1 Each ACK / NACK bit in is associated with each TB in the L TBs.

[0200] As shown in Table 1 below, it is a value table of an NDI bit in the downlink control information.

[0201]

[0202] As shown in Table 2 below, another NDI bit value table in downlink control information is

[0203]

[0204] The first node indicates the HARQ process number of the first TB.

[0205] The first TB is one of the L TBs scheduled by the DCI. For example, the first TB is the first TB block among the L TBs. For another example, the first TB is the xth (x>1)th TB block among the L TBs, where x is a predetermined value or a value configured by the base station. Among the L TBs, the HARQ process number of the other TBs except the first TB is obtained based on the HARQ process number of the first TB. For example, the first association relationship mentioned above is satisfied between the L HARQ process numbers of the L TBs.

[0206] The first node sets the bit value of j bits among the (N+2) bits contained in the first field. For example, j bits are j bits to the left of bit bj among the (N+2) bits contained in the first field. That is, the bit positions of j bits are b0,…,b j-1 . The first node sets the bit state of 1 bit among the j bits to 1, and the first node sets the other j-1 bit states among the j bits to 0. Because there are j bits, there are j bit states with a length of j bits that satisfy that the states of j-1 bits among the j bits are 0 and the state of 1 bit is 1. Therefore, the first node uses the j bit states to respectively indicate the j HARQ process numbers of the first TB. The first node determines the HARQ processnumber of the first TB, and sets the bit states of the j bits according to the association between the HARQ process number of the first TB and the bit states of the j bits. For example, the j bit states of the j bits respectively indicate the j HARQ processnumbers of the first TB. For example, the j HARQ process numbers are 0, 1, .., j-1. Therefore, the first node sets the bit states of the j bits corresponding to the HARQ process number of the first TB according to the HARQprocess number of the first TB.

[0207] Table 3 is a table indicating the HARQ process number of the first TB

[0208]

[0209] For example, if the HARQ process number of the first TB is i, bi is 1, and the states of the other j-1 bits except bi among the j bits are all 0. For example, the first node sets bi to 1, and sets the states of the other j-1 bits except bi among the j bits to 0. The first node sends a DCI to the second node.

[0210] As shown in Table 4, N=8, L=3. The HARQ process number of the first TB is 0 to 5. If the HARQ process number of the first TB is 3, then b3=1, and the state of each bit in b0, b1, b2, b4, and b5 is 0.

[0211] Table 4 shows N=8, L=3, indicating the HARQ process number of the first TB

[0212]

[0213] The specific implementation method of the embodiment of the present application is illustrated below with N=8. Because N=8, the first field contains N+2=10 bits to indicate the HARQ process number of multiple TBs and the indication of the response information. Assume that the 10 bits contained in the first field are b0, b1, ..., b9.

[0214] The first node indicates that the DCI schedules 3 TBs, that is, L=3. Since j=N+1-L, j is equal to 6. The first node sets the b6 bit to 1.

[0215] The first node indicates that the HARQ process number of the first TB among the three TBs scheduled by the DCI is 3. Then the state of the b3 bit among the b0 to b5 bits of the HARQ process number indicated by the first node is 1, and the state of each bit among the b0, b1, b2, b4, and b5 bits is 0. That is, the bit state of the b0 to b5 bits is 000100.

[0216] The first node indicates feedback information of each of the three TBs scheduled by the DCI. Assume that the feedback information is NDI. The NDI indications of the three TBs are 0, 1, 1 respectively. Then the states of bits b7 to b9 are 011.

[0217] In summary, the states of the 10 bits b0 to b9 are 0001001011. The first field in the downlink control information carries b0 to b9, and the first node sends the downlink control information to the user equipment.

[0218] like Figure 4a As shown, the first field provided in the embodiment of the present application includes 10 bits indicating the number of TBs L scheduled by DCI, the HARQ process number of the first TB, and the feedback information of each TB in the L TBs. It is given in detail that when N=8, the number of TBs L scheduled by DCI is 1, 2, ..., 8, the 10 bits (b0-b9) included in the first field indicate the number of TBs scheduled by DCI (or indicate the number of HARQ processes used), the HARQ process number of the first TB, and the feedback information bits corresponding to each TB. Figure 4a Each X in represents a feedback information bit (such as an NDI bit or an ACK / NACK indication bit). Different Xs represent different bits, and therefore have different bit states.

[0219] Embodiment 1b: Another implementation scenario of the embodiment of the present application is described below from the first node side:

[0220] The first node indicates the number of TBs (or the number of HARQ processes used) L scheduled by a DCI.

[0221] The first node determines the number of TBs L scheduled by a DCI, and determines the value of j according to N and L. The first node sets the state of the bj bit in the first field to 0. For example, j=N+1-L.

[0222] The first node indicates the response information of each TB in the L TBs scheduled by the DCI.

[0223] The first node indicates the HARQ process number of the first TB.

[0224] The first association relationship between the first TB and the process numbers of the L HARQ processes is as described above and will not be repeated here.

[0225] The first node sets the bit value of j bits among the (N+2) bits included in the first field. The bit positions of the j bits are as described above. The first node sets the state of 1 bit among the j bits to 0, and the states of the other j-1 bits are all 1. For example, if the HARQ process number of the first TB is i, the first node sets bi=0, and the states of the other j-1 bits among the j bits except bi are all set to 1.

[0226] The following example illustrates the bit status corresponding to the HARQ process number of the first TB when N=8 and L=3. As shown in Table 5, if the HARQ process number of the first TB=3, then b3=0, and the status of each bit in the bits b0, b1, b2, b4, and b5 is 1.

[0227] For example, in Table 5, N=8, L=3, indicating the HARQ process number of the first TB

[0228] Bit status of b0 to b5 HARQ process number of the first TB 011111 0 101111 1 110111 2 111011 3 111101 4 111110 5

[0229] like Figure 4b As shown, it is a schematic diagram of the 10 bits provided in the embodiment of the present application indicating the number of TBs L scheduled by DCI, the HARQ process number of the first TB, and the feedback information of each TB in the L TBs. It is given in detail that when N=8, the number of TBs scheduled by DCI L=1,2,…,8, the 10 bits (b0~b9) contained in the first field indicate the number of TBs scheduled by DCI (or indicate the number of HARQ processes used), the HARQ process number of the first TB, and the feedback information bits corresponding to each TB. The meaning of X is as described above and will not be repeated here.

[0230] Embodiment 1c: The following describes the implementation scenario of the embodiment of the present application from the second node side:

[0231] The second node determines to receive DCI. The DCI can schedule a maximum of N TB blocks.

[0232] N can be a fixed value specified by the standard, or the second node can obtain the N value by receiving the signaling sent by the first node. For example, the first node configures N to the second node through radio resource control signaling, or the first node configures N to the second node through media access control signaling, or the first node configures N to the second node through physical layer signaling. For example, the value set of N is {1,2,4,8}. Or, the value set of N is {2,4,8}. Or, the value set of N is {1,4,8}. Or, the value set of N is {1,2,8}.

[0233] The second node receives the DCI and, based on the N+2 bits (b0, b1, ..., b N+1 ), determine the number of TBs scheduled by DCI (or indicate the number of HARQ processes to be used), the HARQ process number of the first TB, and the feedback information bits corresponding to each TB.

[0234] like Figure 3aAs shown, N+1-L bits of the N+2 bits of the first field indicate the HARQ processnumber of the first TB, L bits of the N+2 bits of the first field indicate feedback information, and one bit of the N+2 bits of the first field is used to indicate the number of TBs scheduled by the DCI (or the number of HARQ processes indicated by the DCI).

[0235] The second node determines the HARQ process number of the first TB scheduled by the DCI.

[0236] For example, in b0,b1,…,b N+1 ), from left to right, determine the bit position of the first bit state being 1. If it is determined that the bi bit is the first bit state being 1, the HARQ process number of the first TB is i. Alternatively, the second node determines the HARQ process number of the first TB according to the correspondence between the bit state and the HARQ process number of the first TB. Alternatively, the second node determines the HARQ process number of the first TB according to the correspondence between the bit state, L, and the HARQ process number of the first TB.

[0237] The second node determines the number of TB blocks (or the number of HARQ processes used) L scheduled by the DCI.

[0238] For example, in (b0, b1, ..., bN+1), from left to right, determine the bit position where the second bit state is 1. If it is determined that the bj bit is the second bit where the bit state is 1, the second node determines that the number of TB blocks (or the number of HARQ processes used) L scheduled by the DCI is equal to N+1-j. Alternatively, the second node determines L based on the correspondence between the bit state, L, and the HARQ processnumber of the first TB.

[0239] The second node determines the HARQ process numbers corresponding to the L TBs scheduled by the DCI.

[0240] The HARQ process numbers of the other TBs except the first TB in the L TBs are determined according to the HARQ process number of the first TB. There is a first association relationship between the process numbers of the L HARQ processes.

[0241] The second node determines HARQ-ACK response information of each TB in the L TBs scheduled by the DCI.

[0242] The second node determines that L bits in the DCI indicate the HARQ-ACK response information of each TB in the L TBs in a bitmap manner. For example, the bit position of the L bits is b j+1,…,b N+1 . The b j+1 ,…,b N+1 Each bit in is the NDI of each TB in L TBs. N+1 Each bit in indicates whether each TB in the L TBs is a new transmission TB or a retransmission TB.

[0243] The following is an example of an embodiment of the present application, in which the second node receives a specific bit state. Assume that N=8. The bit states of the 10 bits (b0~b9) received by the second node are 0110101010. From left to right, the second node determines that the bit position with the first bit state of 1 is b1 (i.e., i=1). Therefore, the HARQ process number of the first TB is determined to be 1. From left to right, the second node determines that the bit position with the second bit state of 1 is b2 (i.e., j=2), and therefore determines that the number of TBs scheduled by DCI is L=N+1-j=8+1-2=7. If the HARQ process number of other TBs is determined in ascending order according to the first TB, the HARQ process number of the other 6 TBs is 2, 3, 4, 5, 6, 7. The second node determines that the 7 bits b3~b9 correspond to the response information of each TB in the 7 TBs. The response information may be NDI, or explicit ACK / NACK information.

[0244] As shown in Table 6, this is a bit table corresponding to NDI

[0245]

[0246] As shown in Table 7, this is a bit table corresponding to NDI

[0247]

[0248]

[0249] Embodiment 1d: Another implementation scenario of the embodiment of the present application is described below from the second node side:

[0250] The second node receives the DCI, the DCI includes a first field, the first field includes N+2 bits. The N+2 bits are denoted as (b0, b1, ..., b N+1 ). The DCI can schedule a maximum of N TB blocks.

[0251] The second node determines the HARQ process number of the first TB scheduled by the DCI.

[0252] For example, in (b0,b1,…,b N+1), from left to right, determine the position of the first bit whose state is 0. If b i The bit is the first bit whose bit state is 0, then the HARQ process number of the first TB is i.

[0253] The second node determines the number of TB blocks (or the number of HARQ processes used by DCI) L scheduled by the DCI.

[0254] For example, in (b0,b1,…,b N+1 ), from left to right, determine the position of the second bit whose state is 0. If b j The bit is the second bit whose bit state is 0, then the second node determines that the number of TB blocks scheduled by DCI (or the number of HARQ processes used) L is equal to N+1-j.

[0255] The second node determines the HARQ process numbers corresponding to the L TBs scheduled by the DCI.

[0256] The second node determines the response information of each TB in the L TBs scheduled by the DCI.

[0257] The second node determines b in the DCI j The L bits to the right of the bit indicate the response information of each TB in the L TBs in a bitmap manner.

[0258] Optionally, in the embodiment of the present application, N=8 or N=4.

[0259] It can be seen from the above examples that in an embodiment of the present application, only 10 bits are needed to support one DCI scheduling any number of TBs among 8 TBs under continuous HARQ process numbers, and the HARQ process number and HARQ-ACK response information of each transmission block can be flexibly indicated, thereby improving the scheduling flexibility and saving the DCI indication overhead.

[0260] Next, another embodiment of the present application is described by way of example.

[0261] The first node sends a first bit to the second node. The first bit is a bit. For example, the DCI includes the first bit. Or, the RRC signaling includes the first bit. The first node uses at most N HARQ process numbers to perform data transmission with the second node, and the N HARQ process numbers are 0, 1, 2, ..., N-1. In an embodiment of the present application, the transmission can be sending or receiving. The node on one side of the communication uses the transmission as sending, and the node on the opposite side of the communication uses the transmission as receiving.

[0262] When the bit state of the first bit is 1, the first bit indicates that the DCI can schedule a maximum of N TBs. Wherein, N is a positive integer greater than 1. The N value is predetermined or indicated by the first node. When the first bit indicates that the DCI can schedule a maximum of N TBs, the TBs scheduled by the DCI may include new transmission TBs and retransmission TBs. When the first bit indicates that the DCI can schedule a maximum of N TBs, the TBs scheduled by the DCI may also be all new transmission TBs. When the first bit indicates that the DCI can schedule a maximum of N TBs, the TBs scheduled by the DCI may also be all retransmission TBs. At this time, the DCI also includes the first field. For example, the N+2 bits contained in the first field indicate multiple TBs according to the method described in Example 1, which will not be repeated here.

[0263] When the bit state of the first bit is 0, the DCI can schedule a maximum of N TBs, or the DCI schedules one TB. When the DCI can schedule a maximum of N TBs, the TBs scheduled by the DCI can only be newly transmitted TBs, or the TBs scheduled by the DCI can only be retransmitted TBs.

[0264] For example, when the bit state of the first bit is 0, the DCI also includes a second bit. The second bit is a bit, and the second bit indicates that the DCI can schedule up to N TBs, or the second bit indicates that the DCI schedules one TB. For example, when the state of the second bit is 1, the second bit indicates that the DCI can schedule up to N TBs. For example, when the state of the second bit is 0, the second bit indicates that the DCI schedules one TB. When the second bit indicates that the DCI can schedule up to N TBs, there is another bit in the DCI to indicate that all the TBs scheduled by the DCI are newly transmitted TBs, or all the TBs scheduled by the DCI are retransmitted TBs. For example, one bit can be an NDI bit. When the second bit indicates that the DCI can schedule up to N TBs, there are N bits in the DCI to indicate N HARQ process numbers in a bitmap manner. Each of the N bits corresponds to a HARQ process number. For example, a bit state of 0 indicates that the HARQ process number corresponding to the bit is not indicated (or used) by the DCI. For example, a bit state of 1 indicates that the HARQ process number corresponding to the bit is indicated (or used) by the DCI. If the HARQ process number is indicated (or used) by the DCI, it means that the DCI schedules a TB related to the HARQ process number. If the HARQ process number is not indicated (or used) by the DCI, it means that the DCI does not schedule a TB related to the HARQ process number. Therefore, the HARQ process number indicated by the DCI is the number of TBs scheduled by the DCI. Therefore, the HARQ process numbers of multiple TBs scheduled by the DCI may be discontinuous.

[0265] As shown in Table 8, it is a correspondence table between N bits and HARQ process number.

[0266]

[0267] When the second bit indicates that the DCI schedules a TB, there are M bits in the DCI to indicate the HARQ process number of the TB, and there is 1 bit in the DCI to indicate the NDI. For example, M is 3, or M is 4, or M is 1.

[0268] When the DCI includes the first bit, the second node determines in which manner the DCI is scheduled according to the first bit and / or the second bit in the DCI. If the state of the first bit is equal to 1, the DCI is scheduled in the first manner. If the state of the first bit is equal to 0 and the state of the second bit is equal to 1, the DCI is scheduled in the second manner. If the state of the first bit is equal to 0 and the state of the second bit is equal to 0, the DCI is scheduled in the third manner.

[0269] The first method: Figure 5a As shown, it is a schematic diagram of the composition structure of a downlink control information provided in an embodiment of the present application. DCI can schedule a maximum of N TBs, and the multiple TBs scheduled by DCI may include both new transmission TBs and retransmission TBs.

[0270] The second method: Figure 5b As shown, it is a schematic diagram of the composition structure of another downlink control information provided in an embodiment of the present application. DCI can schedule a maximum of N TBs, and all the TBs scheduled by DCI are new transmission TBs, or all are retransmission TBs.

[0271] The third method: Figure 5c As shown, it is a schematic diagram of the composition structure of another downlink control information provided in an embodiment of the present application, where DCI schedules a TB.

[0272] As shown in Table 9 below, it is an indication table of DCI scheduling mode

[0273] Bit Status DCI Scheduling Method First bit state = 1 First method The state of the first bit = 0; the state of the second bit = 1 Second method The state of the first bit = 0; the state of the second bit = 0 Third Way

[0274] It should be noted that when the DCI is scheduled in the first manner, the DCI includes the first field, but the DCI does not include the second bit. When the DCI is scheduled in the second manner, the DCI includes the first bit and the second bit, but the DCI does not include the first field, the DCI includes N bits indicating N HARQ process numbers according to the bitmap, and the DCI includes 1 NDI bit. When the DCI is scheduled in the third manner, the DCI includes the first bit and the second bit, but the DCI does not include the first field, the DCI includes M bits indicating the HARQ process number of a TB, and the DCI includes 1 NDI bit. The following example illustrates a structure of a DCI. The first DCI format is a DCI format specified by the standard. For example, the first DCI format is DCI format 6-0A, or the first DCI format is DCI format 6-1A, or the first DCI format is DCI format 6-0B, or the first DCI format is DCI format 6-1B.

[0275] Example 1: The following information is transmitted via the first DCI format.

[0276] The first bit occupies 1 bit.

[0277] The first field occupies (N+2) bits. This field appears only when the first bit is set to 1.

[0278] The second bit occupies 1 bit. This field appears only when the first bit is set to 0.

[0279] HARQ process number, occupies N bits. This field appears only when the second bit is set to 1.

[0280] HARQ process number, occupies M bits. This field appears only when the second bit is set to 0.

[0281] New data indicator, occupies 1 bit. This field appears only when the first bit is set to 0.

[0282] Example 2: The following information is transmitted via the first DCI format.

[0283] The first bit occupies 1 bit.

[0284] The first field occupies (N+2) bits. This field appears only when the first bit is set to 1.

[0285] The second bit occupies 1 bit. This field appears only when the first bit is set to 0.

[0286] HARQ process number, occupies N bits. This field appears only when the second bit is set to 1.

[0287] HARQ ACK indication (or ACK / NACK indication, or NDI indication), occupies 1 bit. This field appears only when the second bit is set to 1.

[0288] HARQ process number, occupies M bits. This field appears only when the second bit is set to 0.

[0289] New data indicator, occupies 1 bit. This field appears only when the second bit is set to 0.

[0290] For another example, if the state of the first bit is equal to 0 and the state of the second bit is equal to 0, the DCI is scheduled according to the second method. If the state of the first bit is equal to 0 and the state of the second bit is equal to 1, the DCI is scheduled according to the third method.

[0291] As shown in Table 10 below, it is an indication table of DCI scheduling mode

[0292] Bit Status DCI Scheduling Method First bit state = 1 First method The state of the first bit = 0; the state of the second bit = 0 Second method The state of the first bit = 0; the state of the second bit = 1 Third Way

[0293] like Figure 5c As shown, in the example of the third mode, the DCI may further include a third bit, and the value of the third bit is 1. For another example, when the DCI is scheduled in the third mode, the DCI also includes a third bit. If the state of the first bit is equal to 1, the DCI is scheduled in the first mode. If the state of the first bit is equal to 0 and the state of the second bit is equal to 1, the DCI is scheduled in the second mode. If the state of the first bit is equal to 0, the state of the second bit is equal to 0, and the state of the third bit is equal to 1, the DCI is scheduled in the third mode. The UE may determine the mode in which the DCI is scheduled based on the state of one or more bits of the first bit, the second bit, and the third bit. Alternatively, the UE determines the bit position in which the first state is 1, starting from the bit position of the first bit. If the bit position in which the first state is 1 is the bit position of the first bit, the DCI is scheduled in the first mode. If the bit position in which the first state is 1 is the bit position of the second bit, the DCI is scheduled in the second mode. If the bit position in which the first state is 1 is the bit position of the third bit, the DCI is scheduled in the third mode.

[0294] Similarly, when DCI is scheduled in the first manner, the DCI includes the first bit, but the DCI does not include the second bit and the third bit. When DCI is scheduled in the second manner, the DCI includes the first bit and the second bit, but the DCI does not include the third bit and the first field. When DCI is scheduled in the third manner, the DCI includes the first bit, the second bit, and the third bit, but the DCI does not include the first field.

[0295] Example 3: The following information is transmitted via the first DCI format.

[0296] The first bit occupies 1 bit;

[0297] The first field occupies (N+2) bits. This field appears only when the first bit is set to 1.

[0298] The second bit occupies 1 bit. This field appears only when the first bit is set to 0.

[0299] HARQ process number, occupies N bits. This field appears only when the second bit is set to 1.

[0300] HARQ ACK indication (or ACK / NACK indication), occupies 1 bit. This field appears only when the second bit is set to 1.

[0301] The third bit occupies 1 bit. When the first bit of this field is set to 0 and the second bit is set to 0, the bit value of this field is fixed to 1 (or fixed to 0) when it appears.
