Technical field

Background technique

Currently, in wireless communication systems, there are downlink transmissions from network equipment to terminal equipment and uplink transmissions from terminal equipment to network equipment.

In uplink transmission, due to cost constraints, terminal equipment often uses relatively inexpensive power amplifiers. The power upper limit of the power amplifier is smaller than the power upper limit of the power amplifier of the network equipment. Therefore, the coverage of the uplink transmission is generally lower than the coverage of the downlink transmission. How to improve the coverage of uplink transmission is the focus of coverage enhancement research.

The uplink transmission channel generally includes the physical uplink control channel (PUCCH) and the physical uplink shared channel (PUSCH). Among them, the PUCCH is a control channel with relatively wide coverage, and the PUSCH is a data channel. The amount of information is large and the coverage is relatively low, so it is very necessary to improve the coverage of PUSCH.

The embodiments of the present application do not limit the specific technology and specific device form adopted by the radio access network device. In this application, wireless access network equipment is referred to as network equipment. If there is no special description, in this application, network equipment refers to wireless access network equipment.

It is understandable that in the embodiments of this application, the physical downlink shared channel (PDSCH), the physical downlink control channel (PDCCH), and the physical uplink shared channel (PUSCH) It is just an example of a downlink data channel, a downlink control channel, and an uplink data channel. In different systems and different scenarios, the data channel and the control channel may have different names, which are not limited in the embodiment of the present application.

At present, different RVs of the same original information can be transmitted on symbols at the same position in multiple consecutive uplink time slots (slots), and one uplink time slot can only be used to transmit one RV.

However, since different RVs of the same original information can only be transmitted on symbols at the same position in multiple consecutive uplink time slots, and the remaining uplink symbols of slot (n+1) only have 2 or 4 available symbols, this will As a result, the uplink symbols in slot(n+1) are not used during uplink transmission, which is not conducive to improving the coverage of uplink transmission.

In the uplink transmission, if the uplink symbols in slot (n+1) in Figure 2 are used, it is possible to increase the coverage of the uplink transmission. In other words, increase the number of uplink symbols used in uplink transmission to increase the coverage of uplink transmission.

In view of this, an embodiment of the present application proposes a communication method. In a retransmission scenario of uplink transmission, a terminal device is made to transmit an RV using uplink symbols in a time slot that includes both downlink symbols and uplink symbols, so as to avoid the inconvenience. The resource waste caused by the unused uplink symbols in the time slots that include downlink symbols and uplink symbols is not used in uplink transmission. At the same time, the time slots that include both downlink symbols and uplink symbols are used in uplink transmission. Compared with the situation where the uplink symbols in the time slots that include both downlink symbols and uplink symbols are not used in uplink transmission, the method provided in this application increases the number of uplink symbols used in uplink transmission, thereby improving uplink transmission Coverage.

Hereinafter, the communication method provided by the embodiment of the present application will be described in detail with reference to FIG. 3 to FIG. 14.

Fig. 3 is a schematic interaction diagram of a communication method provided by an embodiment of the present application. In the following, each step of the method is described in detail.

In the embodiment of the present application, the method 200 will be described by taking a terminal device and a network device as an executor of the method 200 as an example. As an example and not a limitation, the execution subject of the method 200 may also be a chip corresponding to a terminal device and a chip corresponding to a network device.

Step 210: The terminal device reports to the network device that it supports the cross-slot boundary uplink transmission feature.

The terminal device can report to the network device the support for cross-slot boundary transmission characteristics.

For example, the terminal device sends capability indication information to the network device, and the capability indication information indicates that the terminal device supports the cross-slot boundary uplink transmission feature. According to the report of the terminal device, the network device determines that the terminal device supports the cross-time slot boundary uplink transmission feature, and can send DCI or radio resource control (radio resource control, RRC) signaling to the terminal device, and configure the terminal device to support cross-time through DCI or RRC Upstream transmission characteristics of slot boundaries. For example, certain fields in DCI or RRC may be used to indicate that the terminal device can perform uplink transmission based on the cross-slot boundary uplink transmission characteristic.

It should be noted that step 210 may not be necessary. For example, the network device can determine that the terminal device supports the cross-time slot boundary uplink transmission feature through information such as the model of the terminal device and the supported version of the terminal device. In this case, there is no need for the terminal device to send The network device reports that it supports cross-slot boundary uplink transmission characteristics.

Step 220: The network device configures the terminal device to support the uplink transmission feature across the time slot boundary.

In the retransmission scenario, the terminal equipment generates different RVs of the same original information and transmits different RVs of the same original information to the network equipment. The uplink transmission resources used by the terminal equipment to transmit an RV can only occupy one uplink time slot, or when When the terminal device supports the cross-slot boundary uplink transmission feature, the uplink transmission resource used to transmit one RV can occupy at least two uplink time slots. In some embodiments, the network device configures the terminal device to support the cross-slot boundary uplink transmission feature according to the report of the terminal device. In this case, the terminal device can use the uplink transmission resource occupying at least two uplink time slots to transmit an RV.

In other embodiments, the network device may determine that the terminal device supports the cross-slot boundary uplink transmission feature according to information such as the model of the terminal device and the supported version of the terminal device.

This embodiment of the application does not limit this.

Step 230: The network device configures the number of transmissions m.

In the retransmission scenario, the network device configures the number of transmissions m, and the terminal device generates m RVs of the same original information according to the number of transmissions m, where m is an integer greater than or equal to 1.

For example, the network device may indicate the number of transmission m to the terminal device through DCI or RRC.

Step 240: The network device configures uplink transmission resources for the terminal device. Correspondingly, the terminal device determines the uplink transmission resource configured by the network device.

In a retransmission scenario, the network device configures an uplink transmission resource for the terminal device, and the terminal device then determines the uplink transmission resource configured by the network device, so as to send m RVs of the same original information to the network device on the uplink transmission resource. It is worth mentioning that, in this embodiment of the application, the starting time slot of the uplink transmission resource configured by the network device includes both uplink symbols and downlink symbols, and the downlink symbols are earlier than the uplink symbols in time.

For example, a network device can configure uplink transmission resources for a terminal device in the following manner:

Way 1

The network device sends the DCI to the terminal device. The DCI indicates the start symbol of the uplink transmission resource and the length of the uplink transmission resource, and the terminal device determines the uplink transmission resource according to the DCI.

For example, the DCI indicates that the start uplink symbol of the first uplink transmission resource is symbol 10, and indicates that the length of the uplink transmission resource is 30 uplink symbols.

The terminal equipment can determine the starting time slot of the uplink transmission resource according to the time slot carrying the DCI, that is, the time slot corresponding to symbol 10, for example, the time slot in which the terminal device receives the DCI is N, and the terminal equipment can be based on an offset X , It is determined that the starting time slot of the uplink transmission resource is N+X. Among them, X can be defined by the standard, or can be configured by a network device. For example, assuming that X is 4 and the terminal device receives DCI in slot (n-3), the starting time slot is slot (n+1). For the convenience of presentation, the following describes the embodiment of the application with the starting time slot being slot(n+1) as an example. Slot(n+1) includes both uplink symbols and downlink symbols. In mode 1, slot(n +1) The included downlink symbols are symbol 0 to symbol 9, and the included uplink symbols are symbol 10 to symbol 13.

The terminal device can determine that the starting position of the uplink transmission resource in slot(n+1) is symbol 10, and the symbol 10 to symbol 13 in slot(n+1), and the symbol 0 to symbol in slot(n+2) 13 and 12 uplink symbols in slot(n+3) are determined as uplink transmission resources. For slot(n+3), the terminal device can determine any 12 consecutive uplink symbols in slot(n+3) as uplink transmission resources. Part of the transmission resource.

For example, the terminal device may determine symbols 0 to 11 in slot (n+3) as part of the uplink transmission resources, or determine symbols 2 to 13 in slot (n+3) as part of the uplink transmission resources This embodiment of the application does not limit this.

Way 2

The network device sends the DCI to the terminal device. The DCI indicates the start symbol and the end symbol of the uplink transmission resource. The terminal device determines the uplink transmission resource according to the number of time slots occupied by the DCI and the uplink transmission resource.

For example, DCI indicates that the start symbol of the uplink transmission resource is symbol 12, and indicates that the end symbol is symbol 13.

Based on the example in mode 1, it can be seen that the starting time slot determined by the terminal device is slot(n+1), and in mode 2, the uplink symbols included in slot(n+1) are symbol 12 to symbol 13. In addition, the terminal device can determine the end time slot of the uplink transmission resource according to the start time slot of the uplink transmission resource and the number of time slots occupied by the uplink transmission resource. For example, the network device can indicate the number of time slots to the terminal device through RRC. Alternatively, the terminal device may determine the number of time slots according to the number of transmissions m in step 230. For example, the terminal device determines m+k as the number of time slots, and k is an integer greater than or equal to 1.

For example, if the value of the number of transmissions m is 2, and the value of k is 1, the terminal device can determine that the number of time slots occupied by the uplink transmission resource is 3, based on the starting time slot slot(n+1) and the time slot If the number is 3, the terminal device determines that the end slot of the uplink transmission resource is slot(n+3). Since the start symbol is symbol 12 and the end symbol is symbol 13, the terminal device can determine that the uplink transmission resource is in slot(n+1) The start position in is symbol 12, and the end symbol in slot(n+1) is symbol 13, assuming that the start position of uplink transmission resources in slot(n+2) and slot(n+3) are both symbols 0, the terminal device can determine that the start position of the uplink transmission resource in slot(n+2) and slot(n+3) are both symbol 0, and the end position is both symbol 13, and the terminal device will slot(n+1) Symbols 12 to 13 of slot (n+2), symbols 0 to 13 of slot (n+2), and symbols 0 to symbol 13 of slot (n+3) are determined as uplink transmission resources.

Way 3

The network device sends DCI to the terminal device. The DCI indicates the starting symbol of the uplink transmission resource and the length of the uplink symbol occupied by the uplink transmission resource in the starting time slot. The terminal device determines the number of timeslots occupied by the DCI and the uplink transmission resource. Uplink transmission resources.

For example, DCI indicates that the start symbol of the uplink transmission resource is symbol 10, and indicates that the length of the uplink symbol occupied by the uplink transmission resource in the start time slot is 4, and the terminal device can determine that the uplink transmission resource is in the start time slot accordingly. The last symbol occupied is symbol 13. Subsequent time slots that are later than the start time slot in time also use the symbol at the same position as the start time slot as the stop symbol, that is, the terminal device can determine that the uplink transmission time domain resource is after The last uplink symbol occupied in each time slot is symbol 13 of each time slot. Subsequent time slots that are later than the start time slot in time also use the symbol at the same position as the start time slot as the termination symbol, which may be defined by the standard or indicated by the network equipment.

Based on the example in mode 1, it can be seen that the starting time slot determined by the terminal device is slot(n+1), and in mode 3, the uplink symbols included in slot(n+1) are symbol 10 to symbol 13. In addition, the terminal device can determine the end time slot of the uplink transmission resource according to the start time slot of the uplink transmission resource and the number of time slots occupied by the uplink transmission resource. For example, the network device can indicate the number of time slots to the terminal device through RRC. Alternatively, the terminal device may determine the number of time slots according to the number of transmissions m in step 230. For example, the terminal device determines m+k as the number of time slots, and k is an integer greater than or equal to 1.

For example, the number of time slots indicated by the network equipment to the terminal equipment through RRC is 3. Since the start time slot is slot(n+1), the terminal equipment determines that the end time slot of the uplink transmission resource is slot(n+3), slot (n+1) contains uplink symbols from symbol 10 to symbol 13. The terminal device determines that the start position of the uplink transmission resource in slot (n+1) is symbol 10, and the end position is symbol 13, assuming that the uplink transmission resource is in slot (n+1). (n+2) and slot(n+3) are both at the start position of symbol 0, because the position of the end symbol in slot(n+2) and slot(n+3) of the uplink transmission resource is the same as that in slot( The position of the termination symbol in n+1) is the same, the terminal device can determine that the termination symbol of the uplink transmission resource in slot(n+2) and slot(n+3) is the symbol 13. Therefore, the terminal device will slot( Symbols 10 to 13 of n+1), symbols 0 to 13 of slot (n+1), and symbols 0 to 13 of slot (n+3) are determined as uplink transmission resources.

The network device configures multiple sets of parameters to the terminal device through RRC. Each set of parameters includes at least the index number, start symbol, and resource length, and indicates the index number corresponding to a certain set of parameters to the terminal device through DCI. The resource length here can be The length of the uplink symbol occupied by the uplink transmission resource in the start time slot. The terminal device determines the start symbol and resource length corresponding to the index number according to the index number, and determines the start of the uplink transmission resource according to the time slot in which the DCI is received. Time slot, according to the start symbol and resource length, determine the start position of the uplink transmission resource in the start time slot and the end position in the start time slot, and according to the end position of the uplink transmission resource in the start time slot, Determine the end position of the uplink transmission resource in each time slot after the start time slot.

For example, the network device configures two sets of parameters for the terminal device through RRC, namely: (17, 10, 4), (18, 12, 2), and the index number indicated to the terminal device through DCI is 18, and the terminal device determines A set of parameters corresponding to index number 18 is (12, 2). Among them, the start symbol can be determined according to 12 as symbol 12, 2 represents the length of the symbol occupied by the uplink transmission resource in the time slot where the start symbol is located, in other words, 2 represents the uplink transmission resource occupied in the start time slot When the start symbol is symbol 12, 2 means that the symbols occupied by the uplink transmission resource in the start time slot are symbol 12 and symbol 13, and subsequent time slots later than the start time slot in time are also used The symbol at the same position as the start time slot is used as the stop symbol, that is, the terminal device can determine that the last uplink symbol occupied by the uplink transmission time domain resource in each subsequent time slot is the symbol 13 of each time slot. Subsequent time slots that are later than the start time slot in time also use the symbol at the same position as the start time slot as the termination symbol, which may be defined by the standard or indicated by the network equipment.

Based on the example in mode 1, it can be seen that the starting time slot determined by the terminal device is slot(n+1), and in mode 4, the uplink symbols included in slot(n+1) are symbol 12 to symbol 13. In addition, the terminal device can determine the end time slot of the uplink transmission resource according to the start time slot of the uplink transmission resource and the number of time slots occupied by the uplink transmission resource. For example, the network device can indicate the number of time slots to the terminal device through RRC. Alternatively, the terminal device may determine the number of time slots according to the number of transmissions m in step 230. For example, the terminal device determines m+k as the number of time slots, and k is an integer greater than or equal to 1.

The number of time slots indicated by the network equipment to the terminal equipment through RRC is 3. Since the start time slot is slot(n+1), the terminal equipment determines that the end time slot of the uplink transmission resource is slot(n+3), slot(n +1) contains the uplink symbols from symbol 12 to symbol 13. The terminal device determines that the start position of the uplink transmission resource in slot(n+1) is symbol 12, and the end position is symbol 13, assuming that the uplink transmission resource is in slot(n +2) and slot(n+3) are both at the start position of symbol 0, because the position of the end symbol in slot(n+2) and slot(n+3) of the uplink transmission resource is different from that in slot(n+3). The position of the termination symbol in 1) is the same, the terminal device can determine that the termination symbol of the uplink transmission resource in slot(n+2) and slot(n+3) is the symbol 13. Therefore, the terminal device will slot(n+ Symbols 12 to 13 of 1), symbols 0 to 13 of slot (n+1), and symbols 0 to 13 of slot (n+3) are determined as uplink transmission resources.

The network device configures multiple sets of parameters to the terminal device through RRC. Each set of parameters includes at least the index number, start symbol, and resource length, and indicates the index number corresponding to a certain set of parameters to the terminal device through DCI. The resource length here can be The length of the uplink transmission resource configured by the network device for the terminal device. The terminal device determines the start symbol corresponding to the index number and the length of the uplink transmission resource according to the index number, and determines the start of the uplink transmission resource according to the time slot in which the DCI is received. Time slot, combined with the start symbol, determine the starting position of the uplink transmission resource in the initial time slot, and then combined with the length of the uplink transmission resource to determine the uplink transmission resource.

For example, the network device configures four sets of parameters for the terminal device through RRC, namely: (19, 10, 18), (20, 10, 32), (21, 12, 16), (22, 12, 30), And the index number indicated to the terminal device through the DCI is 21, and the terminal device determines that a group of parameters corresponding to the index number 21 is (12, 16). Among them, the starting symbol can be determined according to 12 as symbol 12, 16 represents the length of the uplink transmission resource, in other words, 16 represents the length of the symbol occupied by the uplink transmission resource from the starting symbol, when the starting symbol is symbol 12 When the time, 16 represents that the symbols occupied by the uplink transmission resources are the symbol 12 and the symbol 13 in the starting time slot, and the symbols 0 to 13 of the next time slot that are later than the starting time slot in time.

Based on the example in mode 1, it can be seen that the starting time slot determined by the terminal device is slot(n+1), and in mode 5, the uplink symbols included in slot(n+1) are symbol 12 to symbol 13. The terminal device determines that the starting position of the uplink transmission resource in slot (n+1) is symbol 12. Combining the length of the uplink transmission resource with 16, converts the symbol 12 of slot (n+1) to symbol 13, slot (n+2) Symbols 0 to 13 of are determined as uplink transmission resources.

It should be noted that in Mode 4 and Mode 5, the multiple sets of parameters configured by the network device for the terminal device may also be configured by other signaling, which is not limited in the embodiment of the present application.

Step 250: The terminal device determines m uplink transmission resources for m transmissions according to the uplink transmission resources configured by the network device.

In the following description, the number of uplink symbols in the start time slot in the uplink transmission resource is denoted as N ₁ , and the number of uplink symbols in the uplink transmission resource excluding the start time slot is denoted as N ₂ . For example, the terminal device can determine m uplink transmission resources for m transmissions in the following ways.

Way 1

In an implementation manner, two resource lengths can be determined first, which are respectively denoted as length 1 and length 2. For example, length 1 and length 2 respectively satisfy relational expression (1) and relational expression (2), and the terminal device can be based on the length 1. Length 2, which determines m uplink transmission resources for m transmissions. For example, the terminal equipment may determine the length of the uplink transmission resources for certain transmissions in m transmissions to satisfy length 1, and determine the uplink transmission resources for the other several transmissions. The length of the transmission resource satisfies the length 2.

The terminal device can determine the number of uplink transmission resources meeting the length 1 and the number of uplink transmission resources meeting the length 2 according to the relational formula (3) and relational formula (4):

mod(N ₁ +N ₂ ,m) (3)

m-mod(N ₁ +N ₂ ,m) (4)

For example, m=2, N ₁ =2, N ₂ =28, length 1=15, length 2=15, the terminal equipment determines the number of uplink transmission resources corresponding to length 1 to be 0 according to the relationship (3), according to the relationship Equation (4) determines that the number of uplink transmission resources corresponding to length 2 is 2. As shown in Figure 4, the terminal device combines symbols 12 to 13 in slot(n+1) with symbols in slot(n+2) Symbols 0 to 12 are determined as the uplink transmission resources corresponding to the first transmission, and symbols 13 in slot (n+1) and symbols 0 to 13 in slot (n+2) are determined as the uplink transmission resources corresponding to the second transmission. Transmission resources. It can be seen that the lengths of the uplink transmission resources respectively determined for the two transmissions all satisfy the length 2.

For another example, m = 3, N ₁ = 4, N ₂ = 28, length 1 = 11, and length 2 = 10. The terminal device determines the number of uplink transmission resources corresponding to length 1 to be 2, according to the relational equation (3). Relational equation (4) determines that the number of uplink transmission resources corresponding to length 2 is 1. As shown in Figure 5, the terminal device can combine symbols 10 to 13 in slot(n+1) with slot(n+2) The symbols 0 to 6 of are determined as the uplink transmission resources corresponding to the first transmission, and symbols 7 to 13 in slot(n+2) and symbols 0 to 3 in slot(n+3) are determined as the second For the uplink transmission resource corresponding to the second transmission, symbol 4 to symbol 13 in slot (n+3) are determined as the uplink transmission resource corresponding to the third transmission. It can be seen that the length of the uplink transmission resource determined for the first transmission and the second transmission satisfies the length 1, and the length of the uplink transmission resource determined for the third transmission satisfies the length 2.

Based on the above technical solution, when the uplink transmission resource configured by the network device for the terminal device cannot be divisible by the number of transmissions m, the resource length that satisfies the integer can still be obtained according to the above relational expression (1) and relational expression (2).

In other implementations, only one resource length can be determined. For example, the resource length can satisfy relational formula (5). In this case, it means that the terminal device determines any two uplink transmission resources among m uplink transmission resources for m transmissions. The lengths of the transmission resources are all equal, and they are all l.

l=(N ₁ +N ₂ )/m (5)

Way 2

The terminal device determines the first 14 symbols in the uplink transmission resources as the uplink transmission resources corresponding to the first transmission, and determines the remaining uplink symbols in the uplink transmission resources as the uplink transmission resources corresponding to other transmissions except the first transmission. .

In an implementation manner, two resource lengths can be determined first, which are recorded as length 3 and length 4 respectively. For example, length 3 and length 4 respectively satisfy relational expression (6) and relational expression (7), and the terminal device can be based on the length 3. Length 4, determine m-1 uplink transmission resources for m-1 transmissions. For example, the terminal equipment may determine the length of the uplink transmission resources for certain transmissions in m-1 transmissions to satisfy length 3, which is m The length of the uplink transmission resource determined by the other several transmissions in -1 transmission satisfies the length 3.

The terminal device can determine the number of uplink transmission resources meeting the length 3 and the number of uplink transmission resources meeting the length 4 according to relational equation (8) and relational equation (9):

mod(N ₁ +N ₂ -14,m-1) (8)

m-1-mod(N ₁ +N ₂ -14,m-1) (9)

For example, m=3, N ₁ =2, N ₂ =28, length 3=8, length 4=8, the terminal equipment determines the number of uplink transmission resources corresponding to length 3 to be 0 according to the relation (8), according to the relation Equation (9) determines that the number of uplink transmission resources corresponding to length 4 is 2. As shown in Figure 6, the terminal device combines symbols 12 to 13 in slot(n+1) with symbols in slot(n+2) Symbols 0 to 11 are determined as the uplink transmission resources corresponding to the first transmission, and symbols 12 and 13 in slot (n+2) and symbols 0 to 5 in slot (n+3) are determined as the second transmission. For the corresponding uplink transmission resources, symbols 6 to 13 in slot (n+3) are determined as uplink transmission resources corresponding to the third transmission. It can be seen that the length of the uplink transmission resource determined for the first transmission is 14, and the length of the uplink transmission resource determined for the second transmission and the third transmission meets the length of 4.

For another example, m=3, N ₁ =3, N ₁ =28, length 3=9, length 4=8, and the terminal equipment determines the number of uplink transmission resources corresponding to length 3 to be 1, according to the relationship (8) Relational equation (9) determines that the number of uplink transmission resources corresponding to length 4 is 1. As shown in Figure 7, the terminal device can combine symbols 11 to 13 in slot(n+1) with slot(n+2) The symbol 0 to symbol 10 of is determined as the uplink transmission resource corresponding to the first transmission, and the symbol 11 to symbol 13 in slot(n+2) and the symbol 0 to symbol 5 in slot(n+3) are determined as the second For the uplink transmission resource corresponding to the second transmission, symbol 6 to symbol 13 in slot (n+3) are determined as the uplink transmission resource corresponding to the third transmission. It can be seen that the length of the uplink transmission resource determined for the first transmission is 14, the length of the uplink transmission resource determined for the second transmission satisfies the length of 3, and the length of the uplink transmission resource determined for the third transmission satisfies the length of 4. .

Based on the above technical solution, when the uplink transmission resource configured by the network device for the terminal device cannot be divisible by the number of transmissions m-1, the resource length that satisfies the integer can still be obtained according to the above relational expression (6) and relational expression (7).

In other implementations, only one resource length can be determined. For example, the resource length can satisfy relational equation (10). In this case, it means that the terminal device determines m-1 uplink transmission resources for m-1 transmissions. The lengths of any two uplink transmission resources are equal, and both are 1.

l=(N ₁ +N ₂ -14)/(m-1) (10)

For example, m = 3, N ₁ = 4, N ₂ = 28. As shown in Figure 8, the terminal device can combine symbols 10 to 13 in slot (n+1) with symbol 0 in slot (n+2). To symbol 9 is determined as the uplink transmission resource corresponding to the first transmission, and symbols 10 to 13 in slot(n+2) and symbols 0 to 9 in slot(n+3) are determined to correspond to the second transmission The symbol 10 to symbol 13 in slot (n+3) are determined as the uplink transmission resource corresponding to the third transmission.

Way 4

The terminal equipment determines the uplink symbol in the starting time slot and the 14 symbols in the next time slot later in time than the starting time slot as the uplink transmission resource corresponding to the first transmission, and the remaining uplink transmission resource The symbol is determined as the uplink transmission resource corresponding to the second transmission. In other words, in addition to determining the uplink symbol in the starting time slot as the corresponding uplink transmission resource for the first transmission, the terminal equipment will also determine the 14 symbols in the next time slot that is later than the starting time slot in time. It is the uplink transmission resource corresponding to the first transmission, that is, the uplink symbol in the start time slot and the 14 symbols in the next time slot later than the start time slot together form the uplink corresponding to the first transmission Transmission resources.
