Fig. 1 exemplarily shows one network device and one terminal device, and optionally, the communication system may include a plurality of network devices and each network device may communicate with one or more terminal devices, which is not limited in this embodiment of the present application.

It should be understood that a device having a communication function in a network/system in the embodiments of the present application may be referred to as a communication device. 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 having a communication function, and the network device 110 and the terminal device 120 may be the above-described specific devices, which are not described herein again; the communication device may further include other devices in the communication system, such as other network entities like a network controller, a mobility management entity, and the like, which is not limited in this embodiment.

It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

When the network device 110 and the terminal device 120 communicate with each other, the reliability of data transmission can be improved by repeating data transmission in order to ensure the communication quality. 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 retransmission to be 3 symbols and the number of repetitions of the retransmission to be 3, the terminal device or the network device needs 9 consecutive symbols for the repeated transmission of data according to the related art method. However, since the existing communication system supports flexible timeslot configuration and other transmission of system important information, it is difficult to find continuous time domain resources for repeated transmission of data in the communication system, which may increase the delay of repeated transmission of data between the network device 110 and the terminal device 120.

The present application provides a method and related product for determining time domain resources for data transmission, wherein a target time domain resource for repeated transmission is determined according to a first time domain resource and a 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, 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 a first symbol to a tenth symbol of a 10 th slot, the first time slot resource is a third symbol to a fifth symbol of the 10 th slot, and then the third time slot resource overlapping with the first time slot resource in the second time domain resource can be a third symbol to a fifth symbol of the 10 th slot, the fourth time domain resource may be the first symbol, the second symbol, and the sixth to tenth symbols of the 10 th slot, and further, data may be transmitted on the first symbol, the second symbol, and the sixth to tenth symbols of the 10 th slot, which reduces the length of continuous time domain resources required for data repeat transmission, thereby reducing the delay of data repeat transmission.

Wherein the target time domain resource cannot be earlier than the second time domain resource but may be later than the second time domain resource. The target time domain resource cannot be earlier than the second time domain resource, which 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 follows the first symbol in the second time domain resource. The target time domain resource may be later than the second time domain resource, which may be understood as: the last symbol in the target time domain resource may precede the last symbol in the second time domain resource or the last symbol in the target time domain resource and the last symbol in the second time domain resource may be the same. Or the last symbol in the target time domain resource follows the last symbol in the second time domain resource.

If the repeated transmission is multiple transmissions of a Physical Uplink Control Channel (PUCCH) or a Physical Uplink Shared Channel (PUSCH), the terminal device may determine a 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 send data on the target time domain resource of the repeated transmission. The network device may determine a target time domain resource for 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 for the repeated transmission.

If the repeated transmission is multiple transmissions of a Physical Downlink Control Channel (PDCCH) or a Physical Downlink Shared Channel (PDSCH), the network device may determine a 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 send data on the target time domain resource of the repeated transmission. The terminal device may determine a target time domain resource for 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 for the repeated transmission.

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

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

201. and the terminal equipment 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 repeated transmission may include at least one transmission of an uplink transmission or at least one transmission of a downlink transmission.

The first time domain resource is a time domain resource which 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 determination manner of the first time domain resource may include any one of the following:

first, 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 to the terminal device by the network device. The following embodiments will describe the method for determining the first time domain resource in detail. Wherein the time domain resource indication information comprises the first information and/or the second information. The first information comprises time domain resource information which can not be occupied by the repeated transmission. The second information includes Slot Format Information (SFI), and the SFI includes a semi-static SFI or a dynamic SFI.

And secondly, the first time domain resource is configured to the terminal equipment by the network equipment, the first time domain resource is determined by the network equipment according to the time domain resource indication information, and the mode of determining the first time domain resource by the network equipment according to the time domain resource indication information is the same as the mode of determining the first time domain resource by the terminal equipment according to the time domain resource indication information. For example, the network device may send a DL grant to the terminal device, the DL grant including a first field including first time domain resources. For another example, the network device sends a DL grant to the terminal device, where the DL grant includes a first field, and the first field includes an index value, and the index value indicates the first time domain resource.

The second time domain resource is a time domain resource which is transmitted repeatedly initially, the time domain resource which is transmitted repeatedly initially is a continuous time domain resource, and the determination mode of the second time domain resource may include any one of the following:

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

And secondly, the second time domain resource is determined by the terminal equipment according to the starting time of the first transmission in the repeated transmission, the length of the time domain resource required by each repeated transmission and the TRP switching interval between any two adjacent repeated transmissions. For example, assuming that the starting time of the first transmission in the repeated transmission is the first symbol of the 10 th slot, the length of the time domain resource required for each repeated transmission is 3, and the TRP switching interval between any two adjacent repeated transmissions is 2, the time domain resource of the first transmission in the repeated transmission is the first symbol to the third symbol of the 10 th slot, and if the repeated transmission is 2, the second time domain resource is the first symbol to the eighth symbol of the 10 th slot.

Each Transmission point/reception point (TRP) corresponds to a Transmission Configuration Indicator (TCI) state (TCI state) or corresponds to an index value (index) configured by a higher layer, for example, the higher layer configures an index for each Control-resource set (coreset), and different indexes correspond to different TRPs.

The determining method of the time domain resource of the first transmission in the repeated transmission may include any one of the following:

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

And secondly, the time domain resource of the first transmission in the repeated transmission can be determined according to the starting time of the first transmission in the repeated transmission and the length of the time domain resource required by each repeated transmission. The starting time of the first transmission in the repeated transmission may be configured by the network device, that is, a time slot to which the time domain resource of the first transmission in the repeated transmission belongs, and a first symbol included in the time domain resource of the first transmission in the time slot. The length of the time domain resource required for each repetition transmission may be configurable by the network device, i.e. the number of symbols that can be occupied per repetition transmission. For example, the starting symbol of the first transmission in the repeated transmission is the first symbol of the 10 th slot, and the length of the time domain resource required for each repeated transmission is 2, then the terminal device may determine that the time domain resource of the first transmission in the repeated transmission is the first symbol and the second symbol of the 10 th slot.

Wherein, the number of times of repeating the transmission may be configured by the network device. For example, the network device sends a DL grant to the terminal device, where the DL grant includes a first field, and the first field includes a repetition number of the repeated transmission, for example, a value of the first field is "2", and the terminal device may determine that the repetition number of the repeated transmission is 2 times, that is, the terminal device may perform 2 times repeated transmission on data. For another example, the network device sends the DL grant to the terminal device, where the DL grant includes a first field, and the first field includes an index value, and the index value indicates a repetition number of the repeated transmission, for example, the index value is "010", and the terminal device may determine that the repetition number of the repeated transmission is 2, that is, the terminal device may perform 2 repeated transmissions on data.

The target time domain resource is used for the above repeated transmission, and the target time domain resource may include the fourth time domain resource but not include the third time domain resource, that is, the terminal device may abandon the repeated transmission of the data in the third time domain resource. The target time domain resource may be within one time slot, may span a time slot, or may be over multiple time slots. In a scenario spanning a timeslot or multiple timeslots, the target timeslot resource may be on multiple consecutive timeslots or on multiple non-consecutive timeslots, which is not limited in the embodiments of the present application.

As shown in fig. 4, for example, assuming that the target time domain resources are in one slot, and the symbol 3 to the symbol 5, and the symbol 9 to the symbol 11 are the first time domain resources, and the second time domain resources are the symbol 1 to the symbol 6, then the third time domain resources are the symbol 3 to the symbol 5, and the fourth time domain resources are the symbol 1, the symbol 2, and the symbol 6, and the target time domain resources determined by the terminal device may be the symbol 1, the symbol 2, and the symbol 6. Alternatively, the target time domain resources determined by the terminal device may be symbol 1, symbol 2, symbol 6 to symbol 8, and symbol 12.

202. And the terminal equipment transmits data on the repeatedly transmitted target time domain resource.

When the repeated transmission includes at least one transmission of an uplink transmission, the terminal device may transmit data on a target time domain resource of the repeated transmission. When the repeated transmission includes at least one transmission of a downlink transmission, the terminal device may receive data on a target time domain resource of the repeated transmission. The following embodiments will describe in detail the method of transmitting data on the repeatedly transmitted target time domain resource.

After determining the target time domain resource, the terminal device repeatedly transmits data on 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, the terminal device may receive or transmit data on symbol 1, symbol 2, and symbol 6. Assuming that the target time domain resources are symbol 1, symbol 2, symbol 6 through symbol 8, and symbol 12, the terminal device may receive or transmit data on symbol 1, symbol 2, symbol 6 through symbol 8, and symbol 12.

It can be seen that, in the embodiment of the present application, a target time domain resource for repeated transmission is determined according to a first time domain resource and a second time domain resource in the repeated transmission, where 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, 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, and the target time domain resource includes the fourth time domain resource.

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

301. and the network equipment 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 which 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 comprises the first information and/or the second information. The following embodiments will describe the method for determining the first time domain resource in detail.

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

And secondly, the second time domain resource is determined by the network equipment according to the starting time of the first transmission in the repeated transmission, the length of the time domain resource required by each repeated transmission and the TRP switching interval between any two adjacent repeated transmissions. For example, assuming that the starting time of the first transmission in the repeated transmission is the first symbol of the 10 th slot, the length of the time domain resource required for each repeated transmission is 3, and the TRP switching interval between any two adjacent repeated transmissions is 2, the time domain resource of the first transmission in the repeated transmission is the first symbol to the third symbol of the 10 th slot, and if the repeated transmission is 2, the second time domain resource is the first symbol to the eighth symbol of the 10 th slot.

The time domain resource of the first transmission in the repeated transmission can be determined according to the starting time of the first transmission in the repeated transmission and the length of the time domain resource required by each repeated transmission. For example, the starting symbol of the first transmission in the repeated transmission is the first symbol of the 10 th slot, and the length of the time domain resource required for each repeated transmission is 2, then the terminal device may determine that the time domain resource of the first transmission in the repeated transmission is the first symbol and the second symbol of the 10 th slot.

The target time domain resource is used for the above repeated transmission, and the target time domain resource may include the fourth time domain resource but not include the third time domain resource, that is, the network device may abandon the repeated transmission of the data in the third time domain resource. The target time domain resource may be within one time slot, may span a time slot, or may be over multiple time slots. In a scenario spanning a timeslot or multiple timeslots, the target timeslot resource may be on multiple consecutive timeslots or on multiple non-consecutive timeslots, which is not limited in the embodiments of the present application.

As shown in fig. 4, for example, assuming that the target time domain resources are in one slot, the symbol 3 to the symbol 5, and the symbol 9 to the symbol 11 are the first time domain resources, and the second time domain resources are the symbol 1 to the symbol 6, then the third time domain resources are the symbol 3 to the symbol 5, and the fourth time domain resources are the symbol 1, the symbol 2, and the symbol 6, and the target time domain resources determined by the network device may be the symbol 1, the symbol 2, and the symbol 6. Alternatively, the target time domain resources 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 repeatedly transmitted target time domain resource.

The network device may receive data on a target time domain resource of the repeated transmission when the repeated transmission includes at least one transmission of an uplink transmission. When the repeated transmission includes at least one transmission of the downlink transmission, the network device may transmit data on the target time domain resource of the repeated transmission. The following embodiments will describe in detail the method of transmitting data on the repeatedly transmitted target time domain resource.

After determining the target time domain resource, the network device repeatedly transmits data on 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, the network device may receive or transmit data on symbol 1, symbol 2, and symbol 6. Assuming that the target time domain resources are symbol 1, symbol 2, symbol 6 through symbol 8, and symbol 12, the network device may receive or transmit data on symbol 1, symbol 2, symbol 6 through symbol 8, and symbol 12.

Based on the method for determining time domain resources for data transmission shown in fig. 2 or fig. 3, in the embodiment of the present invention, when the time domain resource indication information is the first information, the time domain resource that is not occupied is determined according to the first information, and the determined time domain resource that is not occupied is used as a first time domain resource scheme for specific description.

Optionally, the first information includes a first time domain resource. The network device configures a plurality of symbols in a certain time slot as non-occupiable time domain resources, and then the network device may generate first information, where the first information includes a slot identifier of the time slot and symbol identifiers of the plurality of symbols that are not occupiable. As shown in fig. 4, the first information includes symbol identifications of symbols 3 to 5 and symbols 9 to 11, and it may be determined that the first time domain resource includes symbols 3 to 5 and symbols 9 to 11.

Optionally, the first information is used to indicate a first time domain resource. For example, the first information may be signal configuration information, which is signal configuration information regarding at least one of: physical Random Access Channel (PRACH), Channel Sounding Reference Signal (SRS), Synchronization Signal Block (SSB), and Positioning Reference Signal (PRS). Since the priority of the signal is higher than that of the repeatedly transmitted data, after receiving the signal configuration information, the terminal device may determine a fifth time domain resource occupied by the signal indicated by the 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 the SSB is symbol 2, and the PUSCH for repeated transmission also occupies symbol 2, then symbol 2 is only available for transmitting the SSB and is not available for transmitting the PUSCH, that is, 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 repeat 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 resource used by the SSB is the same as the frequency domain resource used by the PUSCH, then symbol 2 is only available for transmitting the SSB and is not available for transmitting the PUSCH, that is, symbol 2 is the first time domain resource. Assuming that the signal indicated by the signal configuration information is an SSB, the time domain resource occupied by the SSB is symbol 2, the PUSCH for repeated transmission also occupies symbol 2, and the frequency domain resource used by the SSB is different from the frequency domain resource used by the PUSCH, then symbol 2 may be used for transmitting the SSB and the 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 indicating that the time domain resources occupied by the SSB are symbol 3 to symbol 5 and symbol 9 to symbol 11 in fig. 4, then symbol 3 to symbol 5 and symbol 9 to symbol 11 may be determined as the first time domain resources.

Based on the method for determining time domain resources for data transmission shown in fig. 2 or fig. 3, in the embodiment of the present invention, when the time domain resource indication information is the second information, the time domain resource that is not occupied is determined according to the second information, and the determined time domain resource that is not occupied is used as the first time domain resource scheme for specific description.

The second information is an SFI, and the SFI is used for indicating uplink resources, downlink resources and flexible resources in the timeslot. The SFI may be semi-statically configured through higher layer signaling or dynamically configured through the PDCCH.

If the SFI is configured in a semi-static manner and the repeated transmission is multiple transmissions of the PDSCH or the PDCCH, the first time domain resource includes a semi-statically configured uplink resource, that is, a downlink resource and a flexible resource are time domain resources that can be occupied; or, the first time domain resource includes the uplink resource configured semi-statically 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 which can be occupied; or, the first time domain resource includes a semi-statically configured uplink resource and all flexible resources, that is, the downlink resource is an available time domain resource. As shown in fig. 5, the SFI is configured in a semi-static manner, and the repeated transmission is a multiple transmission of the PUSCH, so that the first time domain resource is one of cases 1 to 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 may determine the first time domain resource according to the dynamic SFI. Specifically, the first time domain resource includes an uplink resource configured by the dynamic SFI, that is, a downlink resource and a flexible resource are time domain resources that can be occupied; or, the first time domain resource includes the uplink resource configured by the dynamic SFI, the nth symbol of the flexible resource, and a portion after the nth symbol, that is, the portion before the nth symbol of the downlink resource and the flexible resource is an occupiable time domain resource; or, the first time domain resource includes an uplink resource configured by the dynamic SFI and all flexible resources, that is, the downlink resource is an available time domain resource. As shown in fig. 6, if the SFI is dynamically configured by the PDCCH and the transmission is repeated for a plurality of times, which is PUSCH transmission, the first time domain resource is one of cases 1 to 3 shown in fig. 6.

If the SFI is configured in a semi-static state and the repeated transmission is a multiple transmission of the PUSCH or PUCCH, the first time domain resource includes a semi-statically configured downlink resource, that is, an uplink resource and a flexible resource are time domain resources that can be occupied; or, the first time domain resource includes a part before the nth symbol of the semi-statically configured downlink resource and the flexible resource, that is, the nth symbol and the part after the nth symbol of the uplink resource and the flexible resource are occupied time domain resources; or, the first time domain resource includes a semi-statically configured downlink resource and all flexible resources, that is, the uplink resource is an available time domain resource. As shown in fig. 7, the SFI is configured in a semi-static manner, and the repeated transmission is multiple transmissions of the PDSCH, so that the first time domain resource is one of cases 1 to 3 shown in fig. 7.

If the SFI is dynamically configured through the PDCCH and repeatedly transmitted for multiple transmissions through the PUSCH or PUCCH, the terminal device may determine the first time domain resource according to the dynamic SFI. Specifically, the first time domain resource includes a downlink resource configured by the dynamic SFI, that is, an uplink resource and a flexible resource are time domain resources that can be occupied; or, the first resource includes a part before the nth symbol of the downlink resource and the flexible resource configured by the dynamic SFI, that is, the nth symbol and the part after the nth symbol of the uplink resource and the flexible resource are time domain resources that can be occupied; or, the first time domain resource includes a downlink resource configured by the dynamic SFI and all flexible resources, that is, the uplink resource is an available time domain resource. As shown in fig. 8, if the SFI is dynamically configured by the PDCCH and the repeated transmission is multiple transmissions of the PDSCH, the first time domain resource is one of cases 1 to 3 shown in fig. 8.

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

In a specific implementation, the time domain resource that is not occupied can be determined according to the first information, and the determined time domain resource that is not occupied is used as the fifth time domain resource. And determining the non-occupiable time domain resource according to the second information, and taking the determined non-occupiable time domain resource as a sixth time domain resource, wherein the first time domain resource is a collection of a fifth time domain resource and the sixth time domain resource.

For a way of determining the non-occupied time domain resource according to the first information, reference may be made to the description of the way of determining the non-occupied time domain resource according to the first information in the foregoing embodiment, and details are not repeated here. In addition, the manner in which the terminal device determines the non-occupied time domain resource according to the second information may refer to the description of the manner in which the non-occupied time domain resource is determined according to the second information in the above embodiment, and is not described herein again.

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

Similarly, when the time domain resource indication information includes the first information and the second information, the first time domain resource is a set of a fifth time domain resource, a sixth time domain resource and a TRP switching interval between any two adjacent repeated transmissions. As shown in fig. 10, a symbol 8 is determined as a fifth time domain resource according to the first information, a symbol 7, a symbol 8 is determined as a sixth time domain resource according to the second information, and the TRP switching interval is defined as a symbol 3 and a symbol 6. Since the first time domain resource is a set of the fifth time domain resource, the sixth time domain resource and the TRP switching interval between any two adjacent repeated transmissions, finally, symbol 3 and symbols 6 to 8 may be determined to be the first time domain resource.

Based on the method for determining time domain resources for data transmission shown in fig. 2 or fig. 3, the embodiment of the present invention specifically describes a scheme for transmitting data on repeatedly transmitted target time domain resources.

The network device may configure the terminal device with: the time domain resource of each of the repeated transmissions is a contiguous time domain resource.

In an embodiment, the time domain resources transmitted each time are the same in length, and the lengths of consecutive time domain resources in the target time domain resources are all greater than or equal to the length of the time domain resource transmitted each time repeatedly.

For example, as shown in fig. 11, it is assumed that symbol 0, symbol 3, symbol 4, symbol 9, and symbol 13 constitute a first time domain resource, and if a starting symbol of a first transmission in a repeated transmission is symbol 0, the network device configures, to the terminal device, that a length of the time domain resource required for each repeated transmission is 3, and a repetition number of the repeated transmission is 2. As can be seen from fig. 11, the time domain resources that can be occupied are symbol 1, symbol 2, symbols 5 to 8, and symbols 10 to 12. Since the symbol 1 and the 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 smaller than the length of the time domain resource required by each repetitive transmission, that is, the first transmission in the repetitive transmission exceeds the time domain length limit boundary, the time domain resource will not be used for the repetitive transmission. In addition, the 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, so that the symbols 5 to 7 in the time domain resource are determined as a part of the target time domain resource for performing the first repeated transmission. The remaining symbol 8 is an available time domain resource, the length of the time domain resource is 1, and the length of the time domain resource is smaller than the length of the time domain resource required for each repetitive transmission, so that the time domain resource is not used for the repetitive transmission. In addition, the symbols 10 to 12 are continuous time domain resources that can be occupied, the length of the time domain resource is 3, the length of the time domain resource is equal to the length of the time domain resource required for each repeated transmission, and then the symbols 10 to 12 in the time domain resource are determined as a part of the target time domain resource for performing the second repeated transmission. And finally, determining the symbols 5 to 7 and the symbols 10 to 12 as target time domain resources, and transmitting the data which is required to be transmitted repeatedly and has the length of 3 and the repetition number of 2 on the target time domain resources.

In an embodiment, if the length of the time domain resource of the nth repeated transmission in the repeated transmission is smaller than the length of the time domain resource required by each repeated transmission, the data is transmitted on the time domain resources of the first to (n-1) th repeated transmissions respectively, n is a positive integer, and n is greater than 0 and less than or equal to the repetition times. That is, the length of the time domain resource of the nth repeated transmission in the repeated transmission is smaller than the length of the time domain resource required by each repeated transmission, that is, the time domain resource of the nth repeated transmission exceeds the time domain length limit boundary, and the data which needs to be repeatedly transmitted for the nth time and the nth later is not transmitted any more.

As shown in fig. 12, a symbol with x represents the first time domain resource, and if the starting symbol is symbol 0, the time domain length a required for one retransmission is 4, the number of retransmissions is 3, and the restriction boundary is symbol 13. Then according to the above method, the target time domain resources for the first repeated transmission are determined to be symbols 5 to 8. At this time, the occupiable time domain resource that does not satisfy the condition before the symbol 13 may be determined as the target time domain resource of the second repeated transmission. The data is not transmitted again for the second and third repetitions. That is, the data to be transmitted is repeatedly transmitted only once at symbols 5 to 8. Therefore, the method of the embodiment can realize repeated transmission of part of data needing repeated transmission under the condition of not increasing time delay, and simultaneously ensures the integrity of each repeated transmission.

Optionally, the extended time domain resource continues to transmit the data that needs to be transmitted for the nth time and after the nth time after the boundary. As shown in fig. 13, a symbol with x in the figure represents a first time domain resource, and if the starting symbol is symbol 0 in slot 1, the time domain length a required for one-time retransmission is 4, the number of times of retransmission is 3, and the limit boundary is symbol 13 in slot 1. Then according to the above method, the target time domain resource of the first repeated transmission is determined to be symbol 5 to symbol 8 in slot 1. At this time, the occupiable time domain resource that does not satisfy the condition before the symbol 13 of the slot 1 may be determined as the target time domain resource of the second repeated transmission. And adding the extended time slot 2 after the time slot 1, and determining symbols 0-7 of the subsequent time slot 2 as target time domain resources of the second repeated transmission and the third repeated transmission. Namely, the transmission length 4 of the symbols 5 to 8 of the time slot 1 and the symbols 0 to 7 of the time slot 2 is determined as a target time domain resource, and data needing to be transmitted repeatedly is transmitted on the target time domain resource. Therefore, by the method of the embodiment, under the condition of ensuring the completeness of the repeated transmission data, the cost of continuous time domain resources can be reduced, so that the time delay is reduced, and the completeness of each repeated transmission is ensured.

Based on the method for determining time domain resources for data transmission shown in fig. 2 or fig. 3, the embodiment of the present invention specifically describes another scheme in which the terminal device transmits data on the repeatedly transmitted target time domain resources.

The network equipment configures the terminal equipment with the following steps: the time domain resource of at least one of the repeated transmissions is a non-contiguous time domain resource. In an embodiment, the length c1 of the currently available time domain resource is smaller than the time domain length a required by one-time repeated transmission, the terminal device splits one-time repeated transmission data into two parts of length c1 and length a-c1, transmits the partial repeated transmission data of length c1 on the available time domain resource of length c1, and transmits the partial repeated transmission data of length a-c1 in the subsequent available time domain resource. If the length c2 of the subsequent occupiable time domain resource is smaller than a-c1, according to the method, the repeated transmission data with the length a-c1 is split into two parts, namely c2 and a-c1-c2, the repeated transmission data with the length c2 is transmitted on the occupiable time domain resource with the length c2, and the repeated transmission data with the length a-c1-c2 is transmitted in the subsequent occupiable time domain resource.

As shown in fig. 14, a symbol with x in the figure represents a first time domain resource, and if the starting symbol is symbol 1, the time domain length a required for one retransmission is 4, and the number of retransmissions is 2. As can be seen from fig. 13, the occupied time domain resources are from symbol 1 to symbol 6 and from symbol 8 to symbol 12, i.e. both c1 and c2 are 6. Therefore, the terminal device performs the first repeat transmission at symbol 1 to symbol 4. At this time, the terminal device may perform a second retransmission at symbol 5, symbol 6, symbol 8, and symbol 9, where the terminal device retransmits the first portion of the data at symbol 5 and symbol 6 and the second portion of the data at symbol 8 and symbol 9.

The first segment may occupy the remaining

symbols

5 and 6 of the time domain resource, and have a length of 2 less than a. And the terminal equipment splits the data of the second repeated transmission into two parts with the length of 2, and transmits the repeated transmission data with the length of 2 of the first part at the symbol 5 and the symbol 6. The second part of the length 2 of the repeated transmission data is transmitted in the subsequently occupiable resources, i.e. symbol 8 and symbol 9.

As shown in fig. 15, a symbol with x represents the first time domain resource, and if the starting symbol is symbol 0, the time domain length a required for one retransmission is 4, and the number of retransmissions is 2. As can be seen from fig. 14, the time domain resources that can be occupied are symbol 1, symbol 2, symbol 4, and symbols 6 to 12, i.e., c1 is 2, c2 is 1, and c3 is 7. Since c1 is smaller than a, the terminal device splits the data of the first repeated transmission into two parts with the length of 2, and transmits the repeated transmission data with the length of 2 in the first part at the symbol 1 and the symbol 2. Since c2 is smaller than the length 2 of the second part of the repeat transmission data, the terminal device splits the second part of the repeat transmission data into two parts each having a length of 1, and transmits the repeat transmission data having the length of 1 in the first part at symbol 4. The second part of the length 1 of the repeat transmission data is transmitted in the subsequent occupiable resource, i.e. symbol 6. That is, the terminal device transmits data repeatedly transmitted for the first time at symbol 1, symbol 2, symbol 4, and symbol 6, and transmits data repeatedly transmitted for the second time at symbol 7 to symbol 10.

In an embodiment, if the nth retransmission exceeds the time domain length limit boundary, the terminal device transmits only the first part of the nth retransmission, and does not transmit the remaining second part of the nth retransmission and the data to be transmitted after the nth retransmission. As shown in fig. 16, a symbol with x represents the first time domain resource, and if the starting symbol is symbol 3, the time domain length a required for one retransmission is 4, the number of retransmissions is 3, and the restriction boundary is symbol 13. The terminal device determines the target time domain resources of the first repeated transmission to be from symbol 5 to symbol 8 according to the method. Since the length of the symbol 11 and the symbol 12 is 2 and less than a, the terminal device splits the data of the second repeated transmission into two parts with the length of 2, and transmits the repeated transmission data with the length of 2 in the first part at the symbol 11 and the symbol 12. At this time, no time domain resource may be occupied before the symbol 13. The terminal device does not transmit the second part of data repeatedly transmitted for the second time and the data repeatedly transmitted for the third time. That is, the terminal device performs one-time retransmission on data to be transmitted only in symbols 5 to 8, and performs second-time retransmission on data with the first part length of 2 in

symbols

11 and 12. Therefore, the method of the embodiment can maximally utilize the occupiable time domain resources existing in the time slot, and realize repeated transmission of part of data needing to be repeatedly transmitted under the condition of not increasing time delay.

Optionally, the terminal device continues to transmit the remaining second part of the nth repeatedly transmitted data and the data to be transmitted after the nth by using the extended time domain resource after the boundary. As shown in fig. 17, a symbol with x in the figure represents a first time domain resource, and if the starting symbol is symbol 3 in slot 1, the time domain length a required for one retransmission is 4, the number of times of retransmission is 3, and the limit boundary is symbol 13 in slot 1. The terminal device determines the target time domain resources of the first repeated transmission to be symbols 5 to 8 in the time slot 1 according to the method. Since the length of the symbol 11 and the symbol 12 is 2 and less than a, the terminal device splits the data of the second repeated transmission into two parts with the length of 2, and transmits the repeated transmission data with the length of 2 in the first part at the symbol 11 and the symbol 12. At this time, no time domain resource may be occupied before symbol 13 of slot 1. And the terminal equipment is added into the extended time slot 2 after the time slot 1, and the second part of data of the subsequent second repeated transmission and the data of the third repeated transmission are transmitted at the symbols 0-5 of the time slot 2. That is, the terminal device transmits data to be repeatedly transmitted with a length of 4 and a repetition number of 3 through symbols 5 to 8 of slot 1,

symbols

11 and 12 and symbols 0 to 5 of slot 2. Therefore, the method of the embodiment can maximally utilize the occupiable time domain resources existing in the time slot under the condition of ensuring the completeness of the repeated transmission data, and reduce the expenditure of continuous time domain resources, thereby reducing the time delay.

In an embodiment, the length c1 of the currently available time domain resource is smaller than the length a of the time domain required by the nth repeated transmission, the terminal device splits the nth repeated transmission data into two parts of a length c1 and a length a-c1, transmits the part of the length c1 of the repeated transmission data on the available time domain resource of the length c1, and does not transmit the remaining part of the length a-c1 of the nth repeated transmission. And performing (n + 1) th repeated transmission in the subsequent time domain resource which can be occupied.

As shown in fig. 18, a symbol with x in the figure represents a first time domain resource, if a starting symbol is symbol 0, a time domain length a required for one retransmission is 4, and the number of times of retransmission is 3, it can be seen from fig. 14 that the occupiable time domain resource is symbol 1, symbol 2, symbol 4, and symbols 6 to 12, that is, c1 is 2, c2 is 1, and c3 is 7. Since c1 is smaller than a, the terminal device splits the data of the first repeated transmission into two parts with the length of 2, transmits the repeated transmission data with the length of 2 in the first part at the symbol 1 and the symbol 2, and does not transmit the remaining repeated transmission data with the length of 2 in the second part. Since c2 is smaller than a, the terminal device splits the data of the second repeated transmission into a first part with the length of 1 and a second part with the length of 3, transmits the repeated transmission data with the length of 1 in the first part at symbol 4, and does not transmit the remaining repeated transmission data with the length of 3 in the second part. Since c3 is larger than a, the terminal device performs a third repeat transmission on symbol 6 to symbol 9. That is, the terminal device transmits the retransmission data with the first partial length of 2 in symbol 1, symbol 2 in the first retransmission, transmits the retransmission data with the first partial length of 1 in symbol 4 in the second retransmission, and transmits all the data in the third retransmission in symbols 6 to 9.

In an embodiment, if the nth retransmission exceeds the time domain length limit boundary, the terminal device transmits only the first part of the nth retransmission, and does not transmit the remaining second part of the nth retransmission and the data to be transmitted after the nth retransmission. As shown in fig. 17, a symbol with x in the figure represents a first time domain resource, and if the starting symbol is symbol 4, the time domain length a required for one retransmission is 4, the number of retransmissions is 3, and the limit boundary is symbol 13. Because the length of the symbols 6 to 8 is 3 less than a, the terminal device splits the data repeatedly transmitted for the first time into a first part with the length of 3 and a second part with the length of 1, transmits the repeatedly transmitted data with the length of 3 in the first part from the symbols 6 to 8, and does not transmit the remaining repeatedly transmitted data with the length of 1 in the second part. Because the length of the symbol 11 and the symbol 12 is 2 and less than a, the terminal device splits the data repeatedly transmitted for the second time into two parts with the length of 2, transmits the repeatedly transmitted data with the length of 2 in the first part at the symbol 11 and the symbol 12, and does not transmit the remaining repeatedly transmitted data with the length of 2 in the second part. At this time, no time domain resource is occupied in the symbols 4 to 13. The terminal device does not transmit the data repeatedly transmitted for the third time. That is, the terminal device transmits only the first retransmission data having the first fractional length of 3 in symbols 6 to 8, and transmits the second retransmission data having the first fractional length of 2 in

symbols

Optionally, the terminal device continues to transmit the remaining second part of the nth repeatedly transmitted data and the data to be transmitted after the nth by using the extended time domain resource after the boundary. As shown in fig. 19, a symbol with x in the figure represents a first time domain resource, and if the starting symbol is symbol 4 in slot 1, the time domain length a required for one retransmission is 4, the number of times of retransmission is 3, and the limit boundary is symbol 13 in slot 1. The terminal device transmits the first partial length of 3 retransmission data for the first retransmission at symbols 6 to 8 and transmits the first partial length of 2 retransmission data for the second retransmission at

symbols

11 and 12 according to the above-described method. At this time, symbols 4 to 13 in slot 1 may not occupy time domain resources. And the terminal equipment adds the extended time slot 2 after the time slot 1 and transmits the data repeatedly transmitted for the third time from the symbol 0 to the symbol 3 of the time slot 2. That is, the terminal device transmits data of length 4 and repetition number 3 through symbol 6 to symbol 8 of slot 1, symbol 11, symbol 12 and symbol 0 to symbol 3 of slot 2. Therefore, the method of the embodiment can maximally utilize the occupiable time domain resources existing in the time slot, and reduce the expenditure of continuous time domain resources, thereby reducing the time delay.

In an embodiment, the length of data transmitted in one repetition is m, the number of times of the repeated transmission is n, and the data to be transmitted in the repetition is transmitted on the continuous time domain resources with the length of m × n from the specified starting symbol. And if the first time domain resource exists in the continuous time domain resources with the length of m x n, the terminal equipment does not transmit the data of the overlapped part of the symbol and the first time domain resource. As shown in fig. 20, a symbol x in the figure represents a first time domain resource, and if a starting symbol is symbol 3, a time domain length a required for one retransmission is 2, and the number of times of retransmission is 4, the repeatedly transmitted data is transmitted in symbols 3 to 10. Since the symbol 5, the symbol 6, the symbol 8 and the symbol 9 are the first time domain resources, the terminal device does not transmit all data of the second repeated transmission, the second part of data of the third repeated transmission and the first part of data of the fourth repeated transmission corresponding to the first time domain resource symbols.

In an embodiment, if the nth retransmission exceeds the time domain length limit boundary, the terminal device transmits only the first part of the nth retransmission, and does not transmit the remaining second part of the nth retransmission and the data to be transmitted after the nth retransmission. As shown in fig. 21, a symbol with x in the figure represents a first time domain resource, and if a starting symbol is symbol 9, a time domain length a required for one retransmission is 2, the number of times of retransmission is 4, and a limit boundary is symbol 13, the repeatedly transmitted data is transmitted in symbols 9 to 13. Since the symbol 9 and the symbol 12 are the first time domain resource, the terminal device does not transmit the first part of data of the first repeated transmission and the second part of data of the second repeated transmission corresponding to the first time domain resource symbol. Since the second part of the third retransmission and the fourth retransmission exceed the boundary symbol 13, the terminal device does not transmit the data of the second part of the third retransmission and the fourth retransmission. That is, the terminal device transmits the second part of data of the first repeated transmission at symbol 10, transmits the first part of data of the second repeated transmission at symbol 11, and transmits the first part of data of the third repeated transmission at symbol 13. Therefore, the method of the embodiment can maximally utilize the occupiable time domain resources existing in the time slot, and realize repeated transmission of part of data needing to be repeatedly transmitted under the condition of not increasing time delay.

Optionally, the terminal device continues to transmit the remaining second part of the nth repeatedly transmitted data and the data to be transmitted after the nth by using the extended time domain resource after the boundary. As shown in fig. 22, a symbol with x in the figure represents a first time domain resource, and if a starting symbol is symbol 9, a time domain length a required for one-time retransmission is 2, the number of times of retransmission is 4, and a limit boundary is symbol 13 in slot 1, 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 resource, the terminal device does not transmit the first part of data of the first repeated transmission and the second part of data of the second repeated transmission corresponding to the first time domain resource symbol. Since the second part of the third retransmission and the fourth retransmission exceed the boundary symbol 13, the terminal device adds the extended slot 2 after the slot 1, and transmits the second part of the third retransmission and the data of the fourth retransmission from the symbol 0 to the symbol 2 of the slot 2. That is, the terminal device transmits the second part of data of the first repeated transmission in symbol 10 of slot 1, transmits the first part of data of the second repeated transmission in symbol 11 of slot 1, transmits the first part of data of the third repeated transmission in symbol 13 of slot 1, and transmits the second part of the third repeated transmission and the data of the fourth repeated transmission in symbols 0 to 2 of slot 2. Therefore, the method of the embodiment can maximally utilize the occupiable time domain resources existing in the time slot, and reduce the expenditure of continuous time domain resources, thereby reducing the time delay.

The scheme of the invention is fully described below in two complete examples. As shown in fig. 23, the repeated transmission is performed in such a manner that each repeated transmission continues, and if the nth repeated transmission exceeds the time domain length limit boundary, the nth repeated transmission continues to be transmitted by the time domain resource after the boundary. Assume that a network device configures a start symbol to a terminal device as 4, a length of a time domain resource required for each repetitive transmission is 2, a gap is 1, a repetition number of the repetitive transmission is 3, a limitation boundary is a symbol 13 in a slot 1, time domain resource indication information includes first information, 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 symbols 3 to 5 and symbols 9 to 11 in the slot 1, and then the terminal device may determine the symbols 3 to 5 and the symbols 9 to 11 in the slot 1 as the first time domain resources. Therefore, after the starting symbol 4 in slot 1, the time domain resources that may be occupied are symbols 6 to 8, 12 and 13 in slot 1. Since the symbols 6 to 8 in the timeslot 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 repetitive transmission, then the symbols 5 to 7 in the time domain resource are determined as a part of the target time domain resource for performing the first repetitive transmission, and the symbol 8 is gap. Since the

symbols

12 and 13 in the 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

symbols

12 and 13 in the time domain resource are determined as a part of the target time domain resource for performing the second repeated transmission. After the starting symbol in slot 1, symbol 13 is preceded by no consecutive time domain resources of a length greater than or equal to the length of the time domain resource required for each repeated transmission. Therefore, the terminal device adds the extended slot 2 after the slot 1, the symbol 0 to the symbol 13 in the slot 2 are continuous occupiable time domain resources, the symbol 0 in the slot 2 is gap, and the symbol 1 and the symbol 2 in the slot 2 are determined as a part of the target time domain resource for performing the third repeated transmission.

As shown in fig. 24, the manner of the repeated transmission is that the time domain resource of at least one repeated transmission in the repeated transmission is a discontinuous time domain resource, and if the nth repeated transmission exceeds the time domain length limit boundary, the terminal device only transmits the first portion of the nth repeated transmission data, and does not transmit the remaining second portion of the nth repeated transmission data and the data that needs to be transmitted after the nth. Suppose that the network device configures a starting symbol to the terminal device as 2, the length of the time domain resource required for each repeated transmission is 3, gap is 1, the number of times of repeated transmission is 3, the limitation boundary is a symbol 13 in a time slot 1, and the time 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. Thus, the first time domain resources are symbol 1, symbol 7, symbol 8 and symbol 13. From this, it can be seen that, starting from the starting symbol, the time domain resources that can be occupied are symbols 2 to 6 and symbols 9 to 12. Since the 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 repetitive transmission, then the symbols 2 to 4 in the time domain resource are determined as a part of the target time domain resource for performing the first repetitive transmission, and the symbol 5 is gap. The remaining symbol 6 is an available time domain resource, the length of the time domain resource is 1, and the length of the time domain resource is smaller than the length of the time domain resource required for each repetitive transmission, so that the terminal device divides the data for the second repetitive transmission into two parts, the length of which is 1 and the length of which is 2, and transmits the first part, the length of which is 1, in the second repetitive transmission using the symbol 6. Since the 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 by the second part of the second repeated transmission, then the

symbols

9 and 10 in the time domain resource are determined as a part of the target time domain resource for transmitting the second part of the second repeated transmission with the length of 2, and the symbol 11 is gap. The remaining symbol 12 is an available time domain resource, the length of the time domain resource is 1, and the length of the time domain resource is smaller than the length of the time domain resource required for each repetitive transmission, so that the terminal device divides the data for the third repetitive transmission into two parts, the length of which is 1 and the length of which is 2, and transmits the first part, the length of which is 1, in the third repetitive transmission using the symbol 12. Since there are no time domain resources that may be occupied from the start symbol 2 to the boundary symbol 13, the terminal device does not transmit the second part of the third retransmission length 2.
