It should be understood that the devices with communication functions in the network/system in the embodiments of the present application may be called communication devices. Taking the communication system shown in FIG. 1 as an example, the communication device may include a network device 110 and a terminal device 120 with communication functions, and the network device 110 and the terminal device 120 may be the specific devices described above, which will not be repeated here.

When the network device 110 and the terminal device 120 communicate, in order to ensure the communication quality, the reliability of data transmission can be improved through repeated data transmission. In the prior art, repeatedly transmitted data needs to be transmitted on continuous time domain resources. For example, assuming that the network device configures the length of the time domain resource required for each repeated transmission to be 3 symbols, and the number of repetitions of the repeated transmission is 3, then according to the method of the prior art, the terminal device or the network device needs 9 consecutive symbols to use For repeated transmission of data. However, because the existing communication system supports flexible time slot configuration and the transmission of other important system information, it is difficult to find continuous time domain resources for repeated data transmission in the communication system, which will increase the network equipment 110 and the terminal equipment 120. The delay between repeated data transmissions.

This application provides a method and related products for determining the time domain resource for data transmission. According to the first time domain resource and the second time domain resource in the repeated transmission, the target time domain resource for the repeated transmission is determined, and the first time domain resource is The time domain resource that cannot be occupied by the repeated transmission, the second time domain resource is the time domain resource of the initial repeated transmission, and the second time domain resource includes a third time domain resource overlapping with the first time domain resource , And a fourth time domain resource other than the third time domain resource, the target time domain resource includes the fourth time domain resource, for example, the second time domain resource is the first symbol to the first symbol of the tenth slot Ten symbols, the first slot resource is the third symbol to the fifth symbol of the 10th slot, then the third slot resource overlapping the first slot resource in the second time domain resource can be the 10th slot resource The third symbol to the fifth symbol of the slot, the fourth time domain resource can be the first symbol, the second symbol, and the sixth symbol to the tenth symbol of the tenth slot, and then the fourth symbol can be in the tenth slot. Data is transmitted on the first symbol, second symbol, and sixth to tenth symbols of the slot, which reduces the length of continuous time domain resources required for repeated data transmission, thereby reducing the time for repeated data transmission. Extension.

Wherein, the target time domain resource cannot be earlier than the second time domain resource, but can be later than the second time domain resource. The target time domain resource cannot be earlier than the second time domain resource. It can be understood as: the first symbol in the target time domain resource is the same as the first symbol in the second time domain resource, or the first symbol in the target time domain resource The symbols are after the first symbol in the second time domain resource. The target time domain resource can be later than the second time domain resource, which can be understood as: the last symbol in the target time domain resource can be before the last symbol in the second time domain resource, or the last symbol in the target time domain resource Same as the last symbol in the second time domain resource. Or the last symbol in the target time domain resource is after the last symbol in the second time domain resource.

If the repeated transmission is multiple transmissions of the Physical Uplink Control Channel (PUCCH) or the Physical Uplink Shared Channel (PUSCH), the terminal device can be based on the first time domain resource in the repeated transmission And the second time domain resource, determine the target time domain resource for repeated transmission, and send data on the target time domain resource for repeated transmission. The network device may determine the target time domain resource of the repeated transmission according to the first time domain resource and the second time domain resource in the repeated transmission, and receive data on the target time domain resource of the repeated transmission.

If the repeated transmission is multiple transmissions of a physical downlink control channel (Physical Downlink Control Channel, PDCCH) or a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), the network device can be based on the first time domain resource in the repeated transmission And the second time domain resource, determine the target time domain resource for repeated transmission, and send data on the target time domain resource for repeated transmission. The terminal device may determine the target time domain resource of the repeated transmission according to the first time domain resource and the second time domain resource in the repeated transmission, and receive data on the target time domain resource of the repeated transmission.

The method for determining the time domain resources of data transmission is described in detail below.

Based on the schematic diagram of the communication system scenario shown in FIG. 1, please refer to FIG. 2. FIG. 2 is a schematic flowchart of a method for determining time domain resources for data transmission according to an embodiment of the present invention. The method shown includes some or All:

201. The terminal device determines the target time domain resource of the repeated transmission according to the first time domain resource and the second time domain resource in the repeated transmission.

Wherein, the repeated transmission may include at least one transmission of uplink transmission or at least one transmission of downlink transmission.

The first time domain resource is a time domain resource that cannot be occupied by the repeated transmission, that is, the repeated transmission can only transmit data on time domain resources other than the first time domain resource. The method for determining the first time domain resource may include any of the following:

1. The first time domain resource may be determined by the terminal device according to the time domain resource indication information, and the time domain resource indication information may be sent by the network device to the terminal device. Subsequent embodiments will introduce in detail the method for determining the first time domain resource. Wherein, the time domain resource indication information includes first information and/or second information. The first information includes the time domain resource information that cannot be occupied by the repeated transmission. The second information includes slot format indicator (SFI), and the SFI includes semi-static SFI or dynamic SFI.

2. The first time domain resource is configured by the network device to the terminal device, the first time domain resource is determined by the network device according to the time domain resource indication information, and the network device determines the first time domain resource according to the time domain resource indication information It is the same as the manner in which the terminal device determines the first time domain resource according to the time domain resource indication information. For example, the network device may send a DL grant to the terminal device, where the DL grant includes the first field, and the first field includes the first time domain resource. For another example, the network device sends a DL grant to the terminal device, where the DL grant includes a first field, the first field includes an index value, and the index value indicates the first time domain resource.

Wherein, the second time domain resource is a time domain resource for initial repeated transmission, and the time domain resource for initial repeated transmission is a continuous time domain resource. The method for determining the second time domain resource may include any of the following:

1. The second time domain resource is determined by the terminal device according to the time domain resource of the first transmission in the repeated transmission, the number of repetitions of the repeated transmission, and the TRP switching interval between any two adjacent repeated transmissions . For example, assuming that the time domain resources of the first transmission in the repeated transmission are the first symbol (ie symbol 0) and the second symbol (ie symbol 1) of the 10th slot, the number of repetitions of the repeated transmission is 2, any The TRP switching interval between two adjacent repeated transmissions is 2, so the second time domain resource is the first symbol to the sixth symbol of the tenth slot.

2. The second time domain resource is the length of the time domain resource required for each repeated transmission according to the start time of the first transmission in the repeated transmission by the terminal device, and the amount of time between any two adjacent repeated transmissions. Determined by the TRP switching interval. For example, suppose that the start time of the first transmission in repeated transmission is the first symbol of the 10th slot, and the length of time domain resources required for each repeated transmission is 3. Between any two adjacent repeated transmissions If the TRP switching interval is 2, then the time domain resource of the first transmission in the repeated transmission is the first symbol to the third symbol of the 10th slot. If the number of repetitions of the repeated transmission is 2, then the second time domain The resources are the first symbol to the eighth symbol of the tenth slot.

Among them, each transmission/reception point (transmission/reception point, TRP) corresponds to a transmission configuration indicator (Transmission Configuration Indicator, TCI) state (TCI state) or corresponds to a high-level configuration index value (index), for example The upper layer configures an index for each control resource set (Control-resource Set, coreset), and different indexes correspond to different TRPs.

Wherein, the method for determining the time domain resource for the first transmission in the repeated transmission may include any of the following:

1. Downlink grant (DL grant) may indicate the time domain resource of the first transmission in the repeated transmission, and the DL grant may be sent by the network device to the terminal device. For example, DL grant indicates that the time domain resources of the first transmission in the repeated transmission are the first symbol (ie, symbol 0) and the second symbol (ie, symbol 1) of the 10th slot.

2. The time domain resource of the first transmission in the repeated transmission may be determined according to the start time of the first transmission in the repeated transmission and the length of the time domain resource required for each repeated transmission. The start time of the first transmission in the repeated transmission may be configured by the network device, that is, the time slot to which the time domain resource of the first transmission in the repeated transmission belongs, and the time of the first transmission in the time slot. The first symbol contained in the domain resource. The length of time domain resources required for each repeated transmission can be configured by the network device, that is, the number of symbols that can be occupied by each repeated transmission. For example, the start symbol of the first transmission in the repeated transmission is the first symbol of the 10th slot, and the length of the time domain resource required for each repeated transmission is 2, then the terminal device can determine the first symbol in the repeated transmission. The transmitted time domain resources are the first symbol and the second symbol of the 10th slot.

Wherein, the number of repetitions of repeated transmission may be configured by the network device. For example, a network device sends a DL grant to a terminal device. The DL grant includes a first field, and the first field includes the number of repetitions of repeated transmission. For example, if the value of the first field is "2", the terminal device can determine the number of repeated transmissions. The number of repetitions is 2, that is, the terminal device can repeat the data transmission twice. For another example, a network device sends a DL grant to a terminal device. The DL grant includes a first field, and the first field includes an index value. The index value indicates the number of repetitions of repeated transmission. For example, the index value is "010", and the terminal device can determine The number of repetitions of repeated transmission is 2, that is, the terminal device can retransmit data twice.

The target time domain resource is used for the foregoing repeated transmission, and the target time domain resource may include the fourth time domain resource but not the third time domain resource, that is, the terminal device may abandon the repeated transmission of data in the third time domain resource. The target time domain resource can be in one time slot, it can also span time slots, or it can be in multiple time slots. In a scenario that spans time slots or multiple time slots, the target time slot resource may be on multiple consecutive time slots or multiple non-continuous time slots, which is not limited in the embodiment of the present application.

As shown in Figure 4, taking the target time domain resource in a time slot as an example, it is assumed that symbols 3 to 5, and symbols 9 to 11 are the first time domain resources, and the second time domain resources are symbols 1 to 6 , Then the third time domain resources are symbol 3 to symbol 5, the fourth time domain resources are symbol 1, symbol 2, and symbol 6, and the target time domain resources determined by the terminal device may be symbol 1, symbol 2, and symbol 6. Optionally, the target time domain resource determined by the terminal device may be symbol 1, symbol 2, symbol 6 to symbol 8, and symbol 12.

202. The terminal device transmits data on the target time domain resource that is repeatedly transmitted.

When the repeated transmission includes at least one transmission of the uplink transmission, the terminal device may send data on the target time domain resource of the repeated transmission. When the repeated transmission includes at least one transmission of the downlink transmission, the terminal device may receive data on the target time domain resource of the repeated transmission. Subsequent embodiments will introduce in detail the method of transmitting data on the target time domain resource that is repeatedly transmitted.

Wherein, the terminal device repeatedly transmits data on the target time domain resource after determining the target time domain resource. As shown in FIG. 4, assuming that the target time domain resources are symbol 1, symbol 2, and symbol 6, then the terminal device can receive or send data on symbol 1, symbol 2, and symbol 6. Assuming that the target time domain resources are symbol 1, symbol 2, symbol 6 to symbol 8, and symbol 12, the terminal device can receive or transmit data on symbol 1, symbol 2, symbol 6 to symbol 8, and symbol 12.

It can be seen that in the embodiment of the present application, the target time domain resource of the repeated transmission is determined according to the first time domain resource and the second time domain resource in the repeated transmission. The first time domain resource is a time domain resource that cannot be occupied by the repeated transmission. The second time domain resource is a time domain resource for initial repeated transmission, and the second time domain resource includes a third time domain resource overlapping with the first time domain resource, and a fourth time domain resource other than the third time domain resource. Time domain resource, the target time domain resource includes the fourth time domain resource, and data is transmitted on the repeatedly transmitted target time domain resource, which reduces the length of continuous time domain resources required for repeated data transmission, thereby reducing Delay due to repeated transmission of data.

Based on the schematic diagram of the communication system scenario shown in FIG. 1, please refer to FIG. 3. FIG. 3 is a schematic flowchart of another method for determining time-domain resources for data transmission according to an embodiment of the present invention. The method shown includes some of the following Or all:

301. The network device determines the target time domain resource of the repeated transmission according to the first time domain resource and the second time domain resource in the repeated transmission.

The first time domain resource is a time domain resource that cannot be occupied by the repeated transmission, that is, the repeated transmission can only transmit data on time domain resources other than the first time domain resource. The first time domain resource may be determined by the network device according to the time domain resource indication information. Wherein, the time domain resource indication information includes first information and/or second information. Subsequent embodiments will introduce in detail the method for determining the first time domain resource.

1. The second time domain resource is determined by the network device according to the time domain resource of the first transmission in the repeated transmission and the number of repetitions of the repeated transmission. For example, assuming that the time domain resources of the first transmission in the repeated transmission are the first symbol and the second symbol of the 10th slot, and the number of repetitions of the repeated transmission is 2, then the second time domain resource is the 10th slot. From the first symbol to the fourth symbol.

2. The second time domain resource is the length of the time domain resource required for each repeated transmission by the network device according to the start time of the first transmission in the repeated transmission, and the amount of time between any two adjacent repeated transmissions. Determined by the TRP switching interval. For example, suppose that the start time of the first transmission in repeated transmission is the first symbol of the 10th slot, and the length of time domain resources required for each repeated transmission is 3. Between any two adjacent repeated transmissions If the TRP switching interval is 2, then the time domain resource of the first transmission in the repeated transmission is the first symbol to the third symbol of the 10th slot. If the number of repetitions of the repeated transmission is 2, then the second time domain The resources are the first symbol to the eighth symbol of the tenth slot.

Wherein, the time domain resource of the first transmission in the repeated transmission can be determined according to the start time of the first transmission in the repeated transmission and the length of the time domain resource required for each repeated transmission. For example, the start symbol of the first transmission in the repeated transmission is the first symbol of the 10th slot, and the length of the time domain resource required for each repeated transmission is 2, then the terminal device can determine the first symbol in the repeated transmission. The transmitted time domain resources are the first symbol and the second symbol of the 10th slot.

Wherein, the target time domain resource is used for the foregoing repeated transmission, and the target time domain resource may include the fourth time domain resource but not the third time domain resource, that is, the network device may abandon the repeated transmission of data in the third time domain resource. The target time domain resource can be in one time slot, it can also span time slots, or it can be in multiple time slots. In a scenario that spans time slots or multiple time slots, the target time slot resource may be on multiple consecutive time slots or multiple non-continuous time slots, which is not limited in the embodiment of the present application.

As shown in Figure 4, taking the target time domain resource in a time slot as an example, it is assumed that symbols 3 to 5, and symbols 9 to 11 are the first time domain resources, and the second time domain resources are symbols 1 to 6 , Then the third time domain resource is symbol 3 to symbol 5, the fourth time domain resource is symbol 1, symbol 2, and symbol 6, and the target time domain resource determined by the network device may be symbol 1, symbol 2, and symbol 6. Optionally, the target time domain resource determined by the network device may be symbol 1, symbol 2, symbol 6 to symbol 8, and symbol 12.

302. The network device transmits data on the target time domain resource that is repeatedly transmitted.

When the repeated transmission includes at least one transmission of the uplink transmission, the network device may receive data on the target time domain resource of the repeated transmission. When the repeated transmission includes at least one transmission of the downlink transmission, the network device may send data on the target time domain resource of the repeated transmission. Subsequent embodiments will introduce in detail the method of transmitting data on the target time domain resource that is repeatedly transmitted.

Among them, the network device repeatedly transmits data on the target time domain resource after determining the target time domain resource. As shown in FIG. 4, assuming that the target time domain resources are symbol 1, symbol 2, and symbol 6, then the network device can receive or send data on symbol 1, symbol 2, and symbol 6. Assuming that the target time domain resources are symbol 1, symbol 2, symbol 6 to symbol 8, and symbol 12, the network device can receive or transmit data on symbol 1, symbol 2, symbol 6 to symbol 8, and symbol 12.

Based on the method for determining the time domain resource for data transmission shown in FIG. 2 or FIG. 3, when the time domain resource indication information is the first information in the embodiment of the present invention, the unoccupiable time domain resource is determined according to the first information, and the above determination is The non-occupiable time domain resources are described in detail as the first time domain resource solution.

Optionally, the first information includes the first time domain resource. The network device configures multiple symbols in a certain time slot as unoccupiable time domain resources, then the network device can generate first information, the first information including the slot identifier of the above-mentioned time slot and the symbol identification of the multiple symbols that are not occupied. As shown in FIG. 4, the first information includes symbol 3 to symbol 5, and symbol identification of symbol 9 to symbol 11. Then, it can be determined that the first time domain resource includes symbol 3 to symbol 5, and symbol 9 to symbol 11.

Optionally, the first information is used to indicate the first time domain resource. For example, the first information may be signal configuration information. The signal configuration information is signal configuration information about at least one of the following signals. The at least one signal is: Physical Random Access Channel (PRACH), Channel Sounding Reference Signal (Sounding Reference Signal). Reference Signal (SRS), Synchronization Signal Block (SSB), and Positioning Reference Signal (PRS). Since the above-mentioned signal has a higher priority relative to the repeatedly transmitted data, after receiving the above-mentioned signal configuration information, the terminal device may determine the fifth time domain resource occupied by the signal indicated by the above-mentioned signal configuration information as the first time domain resource. For example, assuming that the signal indicated by the signal configuration information is SSB, the time domain resource occupied by SSB is symbol 2, and the PUSCH used for repeated transmission also occupies symbol 2, then symbol 2 can only be used to transmit SSB, not PUSCH, that is Say, symbol 2 is the first time domain resource.

The first information may be transmitted through physical layer signaling or higher layer signaling.

Further, the second time domain resource includes the fifth time domain resource, and the frequency domain resource corresponding to the fifth time domain resource in the initial repeated transmission is the same as the frequency domain resource occupied by the signal indicated by the signal configuration information . For example, assuming that the signal indicated by the signal configuration information is SSB, the time domain resource occupied by the SSB is symbol 2, the PUSCH used for repeated transmission also occupies symbol 2, and the frequency domain resources used by the SSB are the same as the frequency domain resources used by the PUSCH, then Symbol 2 can only be used to transmit SSB and cannot be used to transmit PUSCH, that is, symbol 2 is the first time domain resource. Assuming that the signal indicated by the signal configuration information is SSB, the time domain resource occupied by the SSB is symbol 2, the PUSCH used for repeated transmission also occupies symbol 2, and the frequency domain resources used by the SSB and the frequency domain resources used by the PUSCH are different, then the symbol 2 can be used to transmit SSB and PUSCH, that is, symbol 2 is not the first time domain resource.

As shown in FIG. 4, assuming that the first information is signal configuration information, and the signal configuration information includes SSB configuration information, the SSB configuration information indicates that the time domain resources occupied by the SSB are symbols 3 to 5, and symbols 9 to symbols in FIG. 11. Then, symbols 3 to 5, and symbols 9 to 11 can be determined as the first time domain resource.

Based on the method for determining the time domain resource for data transmission shown in FIG. 2 or FIG. 3, when the time domain resource indication information is the second information in the embodiment of the present invention, the unoccupiable time domain resource is determined according to the second information, and the above determination is The non-occupiable time domain resources are described in detail as the first time domain resource solution.

The second information is SFI, and SFI is used to indicate uplink resources, downlink resources, and flexible resources in the time slot. SFI can be configured semi-statically through high-level signaling or dynamically configured through PDCCH.

If SFI is semi-statically configured and repeated transmissions are multiple transmissions of PDSCH or PDCCH, the first time domain resource includes semi-statically configured uplink resources, that is, downlink resources and flexible resources are time domain resources that can be occupied; or A time domain resource includes the semi-statically configured uplink resource and the nth symbol of the flexible resource and the part after the nth symbol, that is, the part before the nth symbol of the downlink resource and the flexible resource is the time domain resource that can be occupied; or , The first time domain resource includes semi-statically configured uplink resources and all flexible resources, that is, the downlink resources are time domain resources that can be occupied. As shown in FIG. 5, the SFI is configured semi-statically, and repeated transmissions are multiple transmissions of the PUSCH, and the first time domain resource is one of Case 1 to Case 3 shown in FIG. 5.

If the SFI is dynamically configured through the PDCCH, and the repeated transmission is multiple transmissions of the PDSCH or the PDCCH, the terminal device can determine the first time domain resource according to the dynamic SFI. Specifically, the first time domain resource includes uplink resources configured by dynamic SFI, that is, downlink resources and flexible resources are time domain resources that can be occupied; or, the first time domain resource includes uplink resources configured by dynamic SFI and the nth of flexible resources. Symbols and the part after the nth symbol, that is, downlink resources and flexible resources. The part before the nth symbol is the time domain resource that can be occupied; or, the first time domain resource includes the uplink resource of the dynamic SFI configuration and all the flexible resources , That is, the downlink resource is the time domain resource that can be occupied. As shown in FIG. 6, the SFI is dynamically configured through the PDCCH, and repeated transmissions are usually multiple transmissions of the PUSCH, and the first time domain resource is one of Case 1 to Case 3 shown in FIG. 6.

If SFI is semi-statically configured and repeated transmissions are multiple transmissions of PUSCH or PUCCH, the first time domain resource includes semi-statically configured downlink resources, that is, uplink resources and flexible resources are time domain resources that can be occupied; or A time domain resource includes the semi-statically configured downlink resource and the part before the nth symbol of the flexible resource, that is, the nth symbol of the uplink resource and the flexible resource and the part after the nth symbol are the time domain resources that can be occupied; or , The first time domain resources include semi-statically configured downlink resources and all flexible resources, that is, the uplink resources are time domain resources that can be occupied. As shown in FIG. 7, SFI is configured semi-statically, and repeated transmissions are multiple transmissions of PDSCH, and the first time domain resource is one of Case 1 to Case 3 shown in FIG. 7.

If the SFI is dynamically configured through the PDCCH, and the repeated transmission is usually multiple transmissions of the PUSCH or PUCCH, the terminal device can determine the first time domain resource according to the dynamic SFI. Specifically, the first time domain resource includes downlink resources configured by dynamic SFI, that is, uplink resources and flexible resources are time domain resources that can be occupied; or, the first resource includes downlink resources configured by dynamic SFI and flexible resources before the nth symbol The part of the uplink resource and the nth symbol of the flexible resource and the part after the nth symbol are the time domain resources that can be occupied; or, the first time domain resource includes the downlink resource of the dynamic SFI configuration and all the flexible resources, namely Uplink resources are time domain resources that can be occupied. As shown in FIG. 8, the SFI is dynamically configured through the PDCCH, and repeated transmission is usually multiple transmissions of the PDSCH, and the first time domain resource is one of Case 1 to Case 3 shown in FIG. 8.

Based on the method for determining the time domain resource for data transmission shown in FIG. 2 or FIG. 3, the embodiment of the present invention specifically describes the solution for determining the first time domain resource when the time domain resource indication information includes the first information and the second information.

In a specific implementation, the unoccupiable time domain resource may be determined according to the first information, and the determined unoccupiable time domain resource may be used as the fifth time domain resource. And determine the unoccupiable time domain resource according to the second information, and use the determined unoccupiable time domain resource as the sixth time domain resource, where the first time domain resource is a collection of the fifth time domain resource and the sixth time domain resource .

The manner of determining the unoccupiable time domain resources according to the first information may refer to the description of the manner of determining the unoccupiable time domain resources according to the first information in the foregoing embodiment, and details are not described herein again. In addition, the manner for the terminal device to determine the unoccupiable time domain resources according to the second information can refer to the description of the manner of determining the unoccupiable time domain resources according to the second information in the foregoing embodiment, which is not repeated here.

As shown in FIG. 9, the symbol 2 is determined as the fifth time domain resource according to the first information, and the symbol 7 and the symbol 8 are determined as the sixth time domain resource according to the second information. Since the first time domain resource is a collection of the fifth time domain resource and the sixth time domain resource, the terminal device can finally determine the symbol 3, the symbol 7 and the symbol 8 as the first time domain resource.

Similarly, when the time-domain resource indication information contains the first information and the second information, the first time-domain resource is the fifth time-domain resource, and the sixth time-domain resource and the TRP switching interval between any two adjacent repeated transmissions Collection. As shown in FIG. 10, symbol 8 is determined as the fifth time domain resource according to the first information, symbol 7 and symbol 8 are determined as the sixth time domain resource according to the second information, and the TRP switching interval is symbol 3 and symbol 6. Since the first time domain resource is the fifth time domain resource, the sixth time domain resource and the collection of the TRP switching interval between any two adjacent repeated transmissions, finally symbol 3 can be determined, and symbols 6 to 8 are the first time. Domain resources.

Based on the method for determining the time-domain resource of data transmission shown in FIG. 2 or FIG. 3, the embodiment of the present invention specifically describes a solution for transmitting data on the target time-domain resource of repeated transmission.

The network device may configure the terminal device: the time domain resource of each repeated transmission in the repeated transmission is a continuous time domain resource.

In an embodiment, the length of the time domain resource for each repeated transmission is the same, and the length of consecutive time domain resources in the target time domain resource is greater than or equal to the length of the time domain resource for each repeated transmission.

For example, as shown in Figure 11, assuming that symbol 0, symbol 3, symbol 4, symbol 9 and symbol 13 constitute the first time domain resource, if the start symbol of the first transmission in repeated transmission is symbol 0, the network device The terminal device configures the length of the time domain resource required for each repeated transmission to be 3, and the number of repetitions for the repeated transmission to be 2. It can be seen from Fig. 11 that the time domain resources that can be occupied are symbol 1, symbol 2, symbol 5 to symbol 8, and symbol 10 to symbol 12. Since symbol 1 and symbol 2 are continuous time-domain resources that can be occupied, the length of the time-domain resource is 2, and the length of the time-domain resource is less than the length of the time-domain resource required for each repeated transmission, that is, the first in repeated transmission. If a transmission exceeds the time domain length limit boundary, then the time domain resource will not be used for repeated transmission. In addition, symbols 5 to 8 are continuous time domain resources that can be occupied. The length of the time domain resource is 4, and the length of the time domain resource is greater than the length of the time domain resource required for each repeated transmission, then the time domain resource The middle symbol 5 to symbol 7 are determined as part of the target time domain resource for the first repeated transmission. The remaining symbol 8 is a time domain resource that can be occupied. The length of the time domain resource is 1, and the length of the time domain resource is less than the length of the time domain resource required for each repeated transmission, then the time domain resource will not be used for repeated transmission . In addition, symbols 10 to 12 are continuous time domain resources that can be occupied. The length of the time domain resource is 3, and the length of the time domain resource is equal to the length of the time domain resource required for each repeated transmission, then the time domain resource The middle symbol 10 to the symbol 12 are determined as a part of the target time domain resource for the second repeated transmission. Finally, symbol 5 to symbol 7 and symbol 10 to symbol 12 are determined as the target time domain resource, and the data that needs to be repeatedly transmitted with a length of 3 and a repetition number of 2 is transmitted on the target time domain resource.

In an embodiment, if the length of the time domain resource for the nth repeated transmission in the repeated transmission is less than the length of the time domain resource required for each repeated transmission, then the transmission is repeated from the first to the n-1th time. The data is respectively transmitted on the time domain resources of, n is a positive integer, n is greater than 0 and less than or equal to the number of repetitions. In other words, the length of the time domain resource for the nth repeated transmission in the repeated transmission is less than the length of the time domain resource required for each repeated transmission, that is, the time domain resource for the nth repeated transmission exceeds the time domain length limit boundary, then The data that needs to be repeatedly transmitted for the nth time and after the nth time is no longer transmitted.

As shown in Figure 12, the symbol x in the figure represents the first time domain resource. If the start symbol is symbol 0, the time domain length a required for one repeated transmission is 4, the number of repeated transmissions is 3, and the limit is the symbol 13. According to the above method, it is determined that the target time domain resource for the first repeated transmission is symbol 5 to symbol 8. At this time, the available time domain resources that did not meet the condition before the symbol 13 may be determined as the target time domain resources for the second repeated transmission. The data is no longer repeated the second and third transmissions. That is, the data that needs to be transmitted is repeatedly transmitted only once at symbol 5 to symbol 8. It can be seen that the method of this embodiment can realize the repeated transmission of part of the data that needs to be repeatedly transmitted without increasing the time delay, while also ensuring the integrity of each repeated transmission.

Optionally, extend the time domain resource after the boundary to continue to transmit the data that needs to be transmitted for the nth time and after the nth time. As shown in Figure 13, the symbol x in the figure represents the first time domain resource. If the starting symbol is the symbol 0 in time slot 1, the time domain length a required for one repeated transmission is 4, and the number of repeated transmissions is 3. , The restriction boundary is symbol 13 in slot 1. Then, according to the above method, the target time domain resource for the first repeated transmission is determined to be symbol 5 to symbol 8 in time slot 1. At this time, the available time domain resources that do not meet the condition before the symbol 13 of the time slot 1 can be determined as the target time domain resources for the second repeated transmission. The extended time slot 2 is added after the time slot 1, and symbols 0 to 7 of the subsequent time slot 2 are determined as the target time domain resources for the second repetitive transmission and the third repetitive transmission. That is, the transmission length 4 of symbol 5 to symbol 8 of time slot 1 and symbol 0 to symbol 7 of time slot 2 is determined as the target time domain resource, and data that needs to be repeatedly transmitted is transmitted on the target time domain resource. It can be seen that the method of this embodiment can reduce the overhead of continuous time domain resources under the condition of ensuring the integrity of the repeated transmission of data, thereby reducing the time delay, and at the same time ensuring the integrity of each repeated transmission.

Based on the method for determining the time domain resource for data transmission shown in FIG. 2 or FIG. 3, the embodiment of the present invention specifically describes another scheme for the terminal device to transmit data on the target time domain resource for repeated transmission.

The network device configures the terminal device: the time domain resource of at least one repeated transmission in the repeated transmission is a non-continuous time domain resource. In an embodiment, the length c1 of the time domain resources that can be currently occupied is less than the time domain length a required for one repeated transmission, and the terminal device splits one repeated transmission data into two parts of length c1 and length a-c1, The part of the length c1 is repeatedly transmitted on the occupied time domain resource of length c1, and the part of the length of a-c1 is repeatedly transmitted in the subsequent occupied time domain resource. If the subsequent time domain resource length c2 that can be occupied is less than a-c1, according to the above method, the repeated transmission data of the length a-c1 is split into two parts c2 and a-c1-c2. When the length of the c2 can be occupied The part of the domain resource with a transmission length of c2 repeatedly transmits data, and the part of the subsequent occupied time domain resource transmits the part of the data with a length of a-c1-c2 repeatedly.

As shown in Figure 14, the symbol x in the figure represents the first time domain resource. If the start symbol is symbol 1, the time domain length a required for one repeated transmission is 4, and the number of repeated transmissions is 2. It can be seen from Figure 13 that the time domain resources that can be occupied are symbol 1 to symbol 6 and symbol 8 to symbol 12, that is, both c1 and c2 are 6. Therefore, the terminal device performs the first repeated transmission at symbol 1 to symbol 4. At this time, the terminal device can perform the second repeated transmission at symbol 5, symbol 6, symbol 8, and symbol 9. The terminal device repeats the first part of the data at symbol 5 and symbol 6, and repeats the data transmission at symbol 8 and symbol 9. The second part.

The first segment can occupy the remaining

symbols

5 and 6 of time domain resources, and the length is 2 less than a. The terminal device splits the data of the second repeated transmission into two parts of length 2, and transmits the first part of repeated transmission data of length 2 in symbol 5 and symbol 6. In the subsequent available resources, that is, symbol 8 and symbol 9 transmit the second part of repeated transmission data with a length of 2.

As shown in Figure 15, the symbol x in the figure represents the first time domain resource. If the start symbol is symbol 0, the time domain length a required for one repeated transmission is 4, and the number of repeated transmissions is 2. It can be seen from Figure 14 that the available time domain resources are symbol 1, symbol 2, symbol 4, and symbol 6 to symbol 12, that is, c1 is 2, c2 is 1, and c3 is 7. Since c1 is smaller than a, the terminal device splits the first repeated transmission data into two parts of length 2, and transmits the first part of repeated transmission data of length 2 in symbol 1 and symbol 2. Since c2 is smaller than the length of the second part of the repeated transmission data 2, the terminal device splits the second part of the repeated transmission data into two parts of length 1, and transmits the first part of the repeated transmission data of length 1 at symbol 4. In the subsequent available resources, that is, the symbol 6 transmits the second part of the repeated transmission data with a length of 1. That is, the terminal device transmits the data for the first repeated transmission at symbol 1, symbol 2, symbol 4, and symbol 6, and transmits the data for the second repeated transmission at symbol 7 to symbol 10.

In one embodiment, if the nth repeated transmission exceeds the time domain length limit boundary, the terminal device only transmits the first part of the nth repeated transmission data, and does not transmit the remaining second part of the nth repeated transmission data and The data to be transmitted after the nth time. As shown in Figure 16, the symbol x in the figure represents the first time domain resource. If the start symbol is symbol 3, the time domain length a required for one repeated transmission is 4, the number of repeated transmissions is 3, and the limit is the symbol 13. Then, the terminal device determines that the target time domain resource for the first repeated transmission is symbol 5 to symbol 8 according to the foregoing method. Since the length of symbol 11 and symbol 12 is 2 less than a, the terminal device splits the data of the second repeated transmission into two parts of length 2, and transmits the first part of repeated transmission data of length 2 in symbol 11 and symbol 12. . At this time, no time domain resources can be occupied before the symbol 13. The terminal device no longer transmits the second part of the data repeatedly transmitted for the second time and the data repeatedly transmitted for the third time. That is, the terminal device only performs one repetitive transmission of the data that needs to be transmitted at symbols 5 to 8, and transmits the first part of the data of length 2 repetitively at

symbols

11 and 12 for the second time. It can be seen that the method of this embodiment can maximize the use of the available time domain resources in the time slot, and realize the repeated transmission of part of the data that needs to be repeatedly transmitted without increasing the time delay.

Optionally, the terminal device extends the time domain resource after the boundary and continues to transmit the remaining second part of the nth repeated transmission data and the data that needs to be transmitted after the nth. As shown in Figure 17, the symbol x in the figure represents the first time domain resource. If the start symbol is symbol 3 in slot 1, the time domain length a required for one repeated transmission is 4, and the number of repeated transmissions is 3. , The restriction boundary is symbol 13 in slot 1. Then, the terminal device determines that the target time domain resource for the first repeated transmission is symbol 5 to symbol 8 in time slot 1 according to the above method. Since the length of symbol 11 and symbol 12 is 2 less than a, the terminal device splits the data of the second repeated transmission into two parts of length 2, and transmits the first part of repeated transmission data of length 2 in symbol 11 and symbol 12. . At this time, there are no available time domain resources before the symbol 13 of the time slot 1. The terminal equipment adds the extended time slot 2 after the time slot 1, and transmits the second part of the subsequent second repeated transmission and the third repeated transmission in the symbol 0 to the symbol 5 of the time slot 2. That is, the terminal device transmits data that needs to be repeatedly transmitted with a length of 4 and a repetition number of 3 through symbols 5 to 8, symbol 11, symbol 12, and symbols 0 to 5 of time slot 2. It can be seen that the method of this embodiment can maximize the use of the occupiable time domain resources existing in the time slot under the condition of ensuring the integrity of repeated transmission data, reduce the expenditure of continuous time domain resources, and thereby reduce the time delay.

In an embodiment, the current available time domain resource length c1 is less than the time domain length a required for the nth repeated transmission, and the terminal device splits the nth repeated transmission data into two lengths c1 and a-c1. Part, the part of length c1 is repeatedly transmitted on the occupied time domain resource of length c1, and the part of length a-c1 remaining in the nth repeated transmission is no longer transmitted. The n+1th repetitive transmission is performed in the subsequent occupied time domain resources.

As shown in Figure 18, the symbol x in the figure represents the first time domain resource. If the start symbol is symbol 0, the time domain length a required for one repeated transmission is 4, and the number of repeated transmissions is 3. It can be seen that the time domain resources that can be occupied are symbol 1, symbol 2, symbol 4, and symbol 6 to symbol 12, that is, c1 is 2, c2 is 1, and c3 is 7. Since c1 is less than a, the terminal device splits the first repeated transmission data into two parts of length 2, and transmits the first part of repeated transmission data of length 2 in symbol 1 and symbol 2, and does not transmit the remaining first part. Two parts of repeated transmission data with a length of 2. Since c2 is less than a, the terminal device splits the data of the second repeated transmission into a first part of length 1 and a second part of length 3, and transmits the first part of repeated transmission data of length 1 in symbol 4, and no longer transmits The remaining second part is repeated transmission data with a length of 3. Since c3 is greater than a, the terminal device performs a third repeated transmission on symbols 6 to 9. That is, the terminal device transmits the repetitive transmission data of length 2 in the first part of the first repetitive transmission at symbol 1, symbol 2, and transmits the repetitive transmission data of length 1 in the first part of the second repetitive transmission at symbol 4, in symbols 6～ Symbol 9 transmits all the data transmitted for the third time.

In one embodiment, if the nth repeated transmission exceeds the time domain length limit boundary, the terminal device only transmits the first part of the nth repeated transmission data, and does not transmit the remaining second part of the nth repeated transmission data and The data to be transmitted after the nth time. As shown in Figure 17, the symbol x in the figure represents the first time domain resource. If the start symbol is symbol 4, the time domain length a required for one repeated transmission is 4, the number of repeated transmissions is 3, and the limit is the symbol 13. Since the length of symbol 6 to symbol 8 is 3 less than a, the terminal device splits the first repeated transmission data into a first part of length 3 and a second part of length 1, and transmits the length of the first part in symbol 6 to symbol 8. The repeated transmission data is 3, and the remaining second part of the repeated transmission data with a length of 1 is no longer transmitted. Since the length of symbol 11 and symbol 12 is 2 less than a, the terminal device splits the data of the second repeated transmission into two parts of length 2, and transmits the first part of repeated transmission data of length 2 in symbol 11 and symbol 12. , The remaining second part of the repeated transmission data with a length of 2 is no longer transmitted. At this time, there are no time domain resources that can be occupied by symbols 4 to 13. The terminal device no longer transmits the data repeatedly transmitted for the third time. That is, the terminal device only transmits the first part of the repetitive transmission data with a length of 3 in the first repeated transmission at symbols 6 to 8, and transmits the first part of the retransmitted data with a length of 2 in the second repeated transmission at

symbols

11 and 12. It can be seen that the method of this embodiment can maximize the use of the available time domain resources in the time slot, and realize the repeated transmission of part of the data that needs to be repeatedly transmitted without increasing the time delay.

Optionally, the terminal device extends the time domain resource after the boundary and continues to transmit the remaining second part of the nth repeated transmission data and the data that needs to be transmitted after the nth. As shown in Figure 19, the symbol x in the figure represents the first time domain resource. If the start symbol is symbol 4 in slot 1, the time domain length a required for one repeated transmission is 4, and the number of repeated transmissions is 3. , The restriction boundary is symbol 13 in slot 1. According to the above method, the terminal device transmits the first part of the repetitive transmission data of length 3 for the first repeated transmission at symbols 6 to 8, and transmits the repetition of the first part length of 2 for the second repeated transmission at

symbols

11 and 12. transfer data. At this time, there are no available time domain resources for symbol 4 to symbol 13 in slot 1. The terminal equipment adds the extended time slot 2 after the time slot 1, and transmits the data of the third repeated transmission in the symbol 0 to the symbol 3 of the time slot 2. That is, the terminal device transmits data that needs to be repeatedly transmitted with a length of 4 and a repetition number of 3 through symbols 6 to 8 of time slot 1, symbol 11, symbol 12, and symbols 0 to 3 of time slot 2. It can be seen that the method of this embodiment can maximize the use of the available time domain resources in the time slot, reduce the expenditure of continuous time domain resources, and thereby reduce the time delay.

In an embodiment, the data length of one repeated transmission is m, and the number of repeated transmissions is n, then the data that needs to be repeatedly transmitted is transmitted on a continuous time domain resource of length m*n starting from the designated start symbol. If the first time domain resource exists in the continuous time domain resource with a length of m*n, the terminal device does not transmit data of the part where the symbol overlaps with the first time domain resource. As shown in Figure 20, the symbol x in the figure represents the first time domain resource. If the start symbol is symbol 3, the time domain length a required for one repeated transmission is 2, and the number of repeated transmissions is 4, then the repeated transmission is Data is transmitted in symbol 3 to symbol 10. Since symbol 5, symbol 6, symbol 8 and symbol 9 are the first time domain resource, the terminal device does not transmit all the data corresponding to the first time domain resource symbol for the second retransmission, and the second part of the third retransmission Data and the first part of the data transmitted for the fourth time.

In one embodiment, if the nth repeated transmission exceeds the time domain length limit boundary, the terminal device only transmits the first part of the nth repeated transmission data, and does not transmit the remaining second part of the nth repeated transmission data and The data to be transmitted after the nth time. As shown in Figure 21, the symbol x in the figure represents the first time domain resource. If the start symbol is symbol 9, the time domain length a required for one repeated transmission is 2, the number of repeated transmissions is 4, and the limit is the symbol 13, the repeatedly transmitted data is transmitted in symbol 9 to symbol 13. Since the symbol 9 and the symbol 12 are the first time domain resources, the terminal device does not transmit the first part of the first repeated transmission and the second part of the second repeated transmission corresponding to the first time domain resource symbol. Since the second part of the third repeated transmission and the fourth repeated transmission exceed the boundary symbol 13, the terminal device does not transmit the second part of the third repeated transmission and the data of the fourth repeated transmission. That is, the terminal device transmits the second part of data for the first repeated transmission at symbol 10, transmits the first part of data for the second repeated transmission at symbol 11, and transmits the first part of data for the third repeated transmission at symbol 13. It can be seen that the method of this embodiment can maximize the use of the available time domain resources in the time slot, and realize the repeated transmission of part of the data that needs to be repeatedly transmitted without increasing the time delay.

Optionally, the terminal device extends the time domain resource after the boundary and continues to transmit the remaining second part of the nth repeated transmission data and the data that needs to be transmitted after the nth. As shown in Figure 22, the symbol x in the figure represents the first time domain resource. If the start symbol is symbol 9, the time domain length a required for one repeated transmission is 2, the number of repeated transmissions is 4, and the limit is time At symbol 13 in slot 1, the repeatedly transmitted data is transmitted in symbol 9 to symbol 13 in slot 1. Since the symbol 9 and the symbol 12 are the first time domain resources, the terminal device does not transmit the first part of the first repeated transmission and the second part of the second repeated transmission corresponding to the first time domain resource symbol. Since the second part of the third repeated transmission and the fourth repeated transmission exceed the boundary symbol 13, the terminal equipment adds the extended time slot 2 after the time slot 1, and the symbol 0 to the symbol 2 in the time slot 2 are repeated for the third time. The second part of the transmission and the fourth repeated transmission of data are transmitted. That is, the terminal equipment transmits the second part of the first repeated transmission at symbol 10 of time slot 1, and transmits the first part of the second repeated transmission at symbol 11 of time slot 1, and transmits the third part of data at symbol 13 of time slot 1. The first part of the data repeatedly transmitted for the first time, the second part of the third repeated transmission and the fourth repeated transmission of data are transmitted in the symbol 0 to the symbol 2 of the time slot 2. It can be seen that the method of this embodiment can maximize the use of the available time domain resources in the time slot, reduce the expenditure of continuous time domain resources, and thereby reduce the time delay.

The solution of the present invention will be fully described in the following two complete embodiments. As shown in FIG. 23, the repeated transmission is continuous for each repeated transmission. If the nth repeated transmission exceeds the time domain length limit boundary, the time domain resources are extended after the boundary to continue to transmit the nth repeated transmission data. Assuming that the network device configures the terminal device with a start symbol of 4, the length of time domain resources required for each repeated transmission is 2, the gap is 1, the number of repetitions of repeated transmission is 3, and the limit boundary is the symbol 13 in time slot 1. The domain resource indication information includes first information, and the first information is signal configuration information, and the signal configuration information includes SSB. The SSB configuration information indicates that the time domain resources occupied by the SSB are symbol 3 to symbol 5 and symbol 9 to symbol 11 in slot 1, so the terminal device can determine symbol 3 to symbol 5 and symbol 9 to symbol 11 in slot 1 as the first A time domain resource. Therefore, after the start symbol 4 in time slot 1, the available time domain resources are symbols 6 to 8, symbol 12 and symbol 13 in time slot 1. Since symbols 6 to 8 in time slot 1 are continuous time domain resources that can be occupied, the length of the time domain resource is 3, and the length of the time domain resource is greater than the length of the time domain resource required for each repeated transmission, then the Symbols 5 to 7 in the time domain resources are determined as part of the target time domain resources for the first repeated transmission, and the symbol 8 is gap. Since

symbols

12 and 13 in time slot 1 are continuous time domain resources that can be occupied, the length of the time domain resource is 2, and the length of the time domain resource is equal to the length of the time domain resource required for each repeated transmission, then the The symbol 12 and the symbol 13 in the time domain resource are determined as a part of the target time domain resource for the second repeated transmission. After the start symbol in the time slot 1, there is no continuous time domain resource with a length greater than or equal to the length of the time domain resource required for each repeated transmission before the symbol 13. Therefore, the terminal equipment joins the extended time slot 2 after the time slot 1, and the symbols 0 to 13 in the time slot 2 are continuous occupable time domain resources. The symbol 0 in the time slot 2 is a gap, and the symbol 0 in the time slot 2 is a gap. Symbol 1 and symbol 2 are determined as part of the target time domain resource for the third repeated transmission.

As shown in Figure 24, the repetitive transmission method is that the time domain resource of at least one retransmission in the repetitive transmission is a non-contiguous time domain resource. If the nth repetitive transmission exceeds the time domain length limit boundary, the terminal device only transmits the first The first part of the data is repeatedly transmitted n times, and the remaining second part of the nth repeated transmission data and the data that need to be transmitted after the nth time are no longer transmitted. Assuming that the network device configures the terminal device with a start symbol of 2, the length of time domain resources required for each repeated transmission is 3, the gap is 1, the number of repetitions of repeated transmission is 3, and the limit boundary is the symbol 13 in time slot 1. The domain resource indication information includes first information and second information. The fifth time domain resource indicated by the first information is symbol 1, the sixth time domain resource indicated by the second information is symbol 7 and symbol 8, and the TRP switching interval between any two adjacent repeated transmissions is symbol 7 and symbol 13. . Therefore, the first time domain resources are symbol 1, symbol 7, symbol 8, and symbol 13. It can be seen that starting from the start symbol, the time domain resources that can be occupied are symbol 2 to symbol 6 and symbol 9 to symbol 12. Since symbols 2 to 6 are continuous time-domain resources that can be occupied, the length of the time-domain resource is 5, and the length of the time-domain resource is greater than the length of the time-domain resource required for each repeated transmission, then the time-domain resource Symbol 2 to symbol 4 are determined as part of the target time domain resource for the first repeated transmission, and symbol 5 is gap. The remaining symbol 6 is a time domain resource that can be occupied. The length of the time domain resource is 1, and the length of the time domain resource is less than the length of the time domain resource required for each repeated transmission. Then the terminal device divides the data of the second repeated transmission They are two parts of length 1 and length 2, and the first part of length 1 in the second repeated transmission of symbol 6 transmission. Since symbols 9 to 12 are continuous time domain resources that can be occupied, the length of the time domain resource is 4, and the length of the time domain resource is greater than the length of the time domain resource required for the second part of the second repeated transmission, then The symbol 9 and the symbol 10 in the time domain resource are determined as a part of the target time domain resource for transmitting the second part of length 2 in the second repeated transmission, and the symbol 11 is gap. The remaining symbol 12 is a time domain resource that can be occupied. The length of the time domain resource is 1, and the length of the time domain resource is less than the length of the time domain resource required for each repeated transmission. Then the terminal device divides the data of the third repeated transmission into They are two parts of length 1 and length 2, and the first part of length 1 in the third repeated transmission of symbol 12 transmission. Since there are no available time domain resources among the start symbol 2 to the boundary symbol 13, the terminal device does not transmit the second part with a length of 2 for the third repetition.
