Description

Data transmission method and device

Technical Field

The present application relates to the field of communications, and in particular, to a method and an apparatus for transmitting data.

Background

In a wireless communication system, according to different frequency bands, the frequency bands can be divided into authorized frequency bands and unauthorized frequency bands. In the unlicensed frequency band, the transmitting node needs to access the signal in a contention manner. In a New Radio (NR) system, support for an NR-U technology is increased, the NR technology is enhanced in an unlicensed frequency band, a more critical characteristic of the NR compared to Long Term Evolution (LTE) is broadband operation (Wideband operation), the reason for this is that the NR supports a larger carrier Bandwidth than the LTE, in order to adapt to different User Equipment (UE) capabilities, a base station may configure different UEs with different transmission bandwidths on a wide carrier, and in a carrier, a continuous transmission Bandwidth is referred to as a Bandwidth part (BWP), and the UE performs data communication with the base station on the configured BWP, so that a low-performance UE may be configured with a narrow BWP by the base station and a high-performance UE may be configured with a wide BWP by the base station. So that one base station can serve UEs of different capabilities. In addition, the base station may configure BWPs of different sizes for different UEs according to different service types, thereby achieving the purpose of saving power consumption. In the LTE technology, the UE and the base station work in the same bandwidth, and efficient resource allocation cannot be achieved.

In addition, considering that the NR supports wideband operation, in order to avoid that a large-capacity bit Transport Block (TB) transmission error on a large BWP causes the need of retransmission of the whole TB, the NR also supports a Code Block Group (CBG) based transmission mode. Meanwhile, the NR also supports a resource scheduling method of scheduling multiple transmission time intervals (Multi-TTI) by one Downlink control signaling (DCI), which is different from the conventional method of scheduling one TB by one DCI, and the resource scheduling method of Multi-TTI supports scheduling multiple TBs by one DCI, so as to achieve the purpose of saving the overhead of control signaling, which can be understood as "fast uplink data scheduling".

In the unlicensed frequency band, in order to ensure fairness of accessing the channel by using the user in the frequency band, the transmitting node needs to access the channel in a competitive manner, that is, the busy and idle states of the channel need to be monitored before accessing the channel. When the channel energy sensed by the transmitting node is lower than a preset threshold, the channel can be judged to be idle. Only when the channel is idle, the node can access the channel to transmit signals, so that compared with the authorized frequency band, the communication in the unauthorized frequency band has certain uncertainty.

In view of this, how to implement fast uplink data scheduling in the unlicensed frequency band is a problem to be solved.

Disclosure of Invention

The application provides a data transmission method, which is used for providing a method for realizing fast uplink data scheduling in an unlicensed frequency band. More specifically, the present application provides a method capable of solving the problem that RV versions of multiple sub data blocks that are rescheduled differently cannot be flexibly indicated in an uplink rescheduling mechanism.

In a first aspect, a method for transmitting data is provided, the method including: a terminal device receives first indication information, where the first indication information is used to indicate that a first sub data block is sent through a first uplink shared channel (PUSCH), and if the first indication information is received in a first time period, the first sub data block and a second sub data block have the same redundancy version RV number, the second sub data block is a sub data block that fails to be sent through a second PUSCH, and the first sub data block and the second sub data block belong to one data block, and further, the first sub data block and the second sub data block are the same sub data block of the same data block; and the terminal equipment sends the first sub data block through the first PUSCH according to the first indication information. The first PUSCH and the second PUSCH may be the same PUSCH or different PUSCHs, and the present application is not limited herein.

Based on the above scheme, the terminal device receives the first indication information in the first period, and sends the first sub data block through the first PUSCH, even if the content of the first indication information does not indicate the RV number of the first sub data block, the RV numbers of the first sub data block and the second sub data block are the same, where the second sub data block is a sub data block that has failed to be sent due to LBT failure of the second PUSCH and the like in the past, and the same RV number means that the first sub data block and the second sub data block belong to the same data block, and for example, the first sub data block and the second sub data block may be the same sub data block of the same data block. Therefore, on the premise of not modifying DCI, when the demodulation of the previous part of the data blocks is not completed, the network equipment judges whether the data is successfully transmitted or not according to the energy of the received demodulation reference signal of the uplink data, and can directly reschedule the sub data blocks which are not successfully transmitted due to LBT and the like, thereby reducing the waiting time of the terminal equipment, reducing the time delay of uplink transmission, and solving the problem that the RV numbers of a plurality of different rescheduled sub data blocks cannot be flexibly indicated in an uplink rescheduling mechanism.

It should be understood that, in the above scheme, the content carried in the first sub data block and the content carried in the second sub data block are the same, but the configuration parameters of the two sub data blocks may be different, for example, the Modulation and Coding Scheme (MCS) scheduling order of the two sub data blocks may be different, and in addition, the scheduled time-frequency resource of the first sub data block and the scheduled time-frequency resource of the second sub data block may also be different, which is not limited herein. With reference to the first aspect, in some possible designs, if the terminal device receives the first indication information at a time other than the first time period, the first indication information is further used to indicate an RV number of the first sub data block.

In the above scheme, when the terminal device does not receive the first indication information within the first period, the first indication information is further used for indicating the RV number of the first sub data block. The RV number of the first sub-data block has no relation with the RV number of the second sub-data block, and the terminal equipment determines the RV number of the first sub-data block according to the first indication information and is not the same as the RV number of the second sub-data block by default. With reference to the first aspect, in some possible designs, the terminal device receives second indication information, where the second indication information is used to indicate a duration of the first period; and the terminal equipment determines the first time period according to the second indication information, wherein the starting time of the first time period is the time for scheduling the second sub data block to be sent.

Based on the above scheme, the terminal device determines the first time period by receiving the second indication information, so that the first time period is taken as a boundary, and when the first indication information is received within the first time period, the RV number of the first sub data block is the same as the RV number of the second sub data block; and when the first indication information is received at a time other than the first period, determining the RV number of the first sub data block according to the first indication information.

With reference to the first aspect, in some possible designs, the terminal device receives third indication information, where the third indication information is used to indicate that a first sending position of at least one sub data block of a plurality of data blocks is adjusted, where any data block of the plurality of data blocks includes at least two sub data blocks; and the terminal equipment sends the at least one sub data block at a second sending position through a third PUSCH, wherein the second sending position is the adjusted time-frequency position for sending the at least one sub data block.

Based on the above scheme, the terminal device adjusts the first transmission position of at least one sub data block of the plurality of data blocks by receiving the third indication information, and transmits the at least one sub data block at the second transmission position through the third PUSCH. Therefore, when the network device schedules a plurality of data blocks, the transmission position of the sub data blocks on the available transmission resources (such as the transmission channel with successful LBT) can be adjusted, so that the transmission delay of partial data blocks is reduced, and the signaling overhead of rescheduling can be reduced.

It should be understood that, in the above technical solution, the third indication information only indicates that the terminal device adjusts the first sending position of at least one sub data block of the plurality of data blocks, and is not used for indicating a specific adjustment manner.

Based on the above scheme, the terminal device firstly adjusts the first sending position according to the HARQ ID of at least one sub data block, and on this basis, when the HARQ IDs of at least two sub data blocks are the same, the terminal device adjusts according to the corresponding transmission channel ID to obtain the second sending position.

The network device and the terminal device can be configured with a plurality of antennas, and the network device and the terminal device can communicate by using a multi-antenna technology.

Fig. 2 is another schematic diagram of a wireless communication system 200 suitable for use with embodiments of the present application. As shown in fig. 2, the wireless communication system 200 may include a terminal device, such as terminal device 221 in fig. 2; the wireless communication system 200 may also include a plurality of network devices, such as the network device 211 and the network device 212 of fig. 2. Terminal device 221 in fig. 2 may communicate with network device 221 and network device 212 simultaneously; alternatively, network device 211 and network device 212 may jointly provide services for terminal device 221.

It should be understood that fig. 1 and 2 are only exemplary, and the present application is not limited thereto.

It should also be understood that the network device in the wireless communication system may be any device with wireless transceiving function. The apparatus includes, but is not limited to: a Base Station Controller (BSC), a Base Transceiver Station (BTS), a Home Base station (e.g., home evolved NodeB, or Home node B, HNB), a baseband unit (Base band unit, BBU), an Access Point (AP), a Wireless relay node, a Wireless backhaul node, a Transmission Point (TP), or a Transmission and Reception Point (TRP) in a Wireless fidelity (WIFI) system, such as a gNB or a Transmission point (TRP or TP) in an NR system, an antenna panel of one or a group (including multiple antenna panels) of Base stations in a 5G system, or a network node forming the gNB or the Transmission point, such as a baseband unit, or a Distributed Unit (DU), etc.

In some deployments, the gNB may include a Centralized Unit (CU) and a DU. The gNB may also include an Active Antenna Unit (AAU). The CU implements part of the function of the gNB and the DU implements part of the function of the gNB. For example, the CU is responsible for processing non-real-time protocols and services, and implements functions of a Radio Resource Control (RRC) layer and a Packet Data Convergence Protocol (PDCP) layer. The DU is responsible for processing a Physical layer protocol and a real-time service, and implements functions of a Radio Link Control (RLC) layer, a Media Access Control (MAC) layer, and a Physical (PHY) layer. The AAU implements part of the physical layer processing functions, radio frequency processing and active antenna related functions. Since the information of the RRC layer eventually becomes or is converted from the information of the PHY layer, the higher layer signaling, such as RRC layer signaling, can also be considered as being transmitted by the DU or by the DU + AAU under this architecture. It is to be understood that the network device may be a device comprising one or more of a CU node, a DU node, an AAU node. In addition, the CU may be divided into network devices in a Radio Access Network (RAN), or may be divided into network devices in a Core Network (CN), which is not limited in this application.

The terminal device in the embodiment of the present application may be a Mobile phone (Mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in Industrial control (Industrial control), a wireless terminal in Self-driving (Self-driving), a wireless terminal in Remote medical (Remote medical), a wireless terminal in Smart grid (Smart grid), a wireless terminal in Transportation safety (Transportation safety), a wireless terminal in Smart city (Smart city), a wireless terminal in Smart home (Smart home), and the like. The embodiments of the present application do not limit the application scenarios.

In order to facilitate understanding of the embodiments of the present application, a brief description of several terms referred to in the present application will be provided below.

1. Listen before talk "

The "listen before talk" (LBT), or "listen before transmit", is a widely used technique in unlicensed frequency bands, in which a radio transmitter first listens to its radio environment before starting transmission, detects whether a channel is idle, and waits for transmission when the channel is idle if the channel is in a busy state, so as to avoid channel access collision and implement channel spectrum sharing. The following is a brief introduction to the content of the LBT mechanism:

(1) Before sending data, whether a channel is used or not is firstly detected, and if the channel is detected to be busy, the data is sent after waiting for a random time.

(2) If the receiving end receives the frame data correctly, after a period of time, the receiving end sends an acknowledgement frame ACK to the sending end.

(3) The sending end receives the ACK frame, determines that the data is correctly transmitted, and after a time interval, an idle time (called a contention window) occurs, which indicates that each device contends for the channel.

2. Redundancy version

The redundancy version is designed to implement Incremental Redundancy (IR) Hybrid automatic repeat request (HARQ) transmission, that is, redundancy bits generated by an encoder are divided into a plurality of groups, each redundancy version defines a transmission start point, and different RVs are respectively used for first transmission and each HARQ retransmission to implement gradual accumulation of the redundancy bits and complete Incremental redundancy HARQ operation. Taking NR as an example, the number of RVs is 4. The definition of the RV is related to the size of a Soft buffer (Soft buffer), the smaller of a transmitting end circular buffer and a receiving end Soft buffer is selected, and 4 RVs are uniformly distributed in the range.

3. Transmission block

Transport Block (TB), one Transport block is a data block containing MAC PDU, and this data block is transmitted in one TTI and is also a unit of HARQ retransmission. One terminal can transmit two transport blocks at most in one TTI. For a network device, the transport blocks scheduled for one TTI may be greater than or equal to two, since the network device may schedule multiple UEs simultaneously. TB is a concept of MAC.

4. Time slot

Slot (slot): in NR, a slot is a minimum scheduling unit of a time domain. One slot format is to contain 14 Orthogonal Frequency Division Multiplexing (OFDM) symbols, and the CP of each OFDM symbol is a normal CP (normal CP); one slot format is to include 12 OFDM symbols, and the CP of each OFDM symbol is an extended CP (extended CP); one slot format is to contain 7 OFDM symbols, each of which has a normal CP. The OFDM symbols in one slot may be all used for uplink transmission; can be used for downlink transmission; or one part can be used for downlink transmission, one part can be used for uplink transmission, and one part is reserved for no transmission. It should be understood that the above examples are illustrative only and should not be construed as limiting the present application in any way. The slot format is not limited to the above example for system forward compatibility considerations.

5. Code block group retransmission

Code Block Group (CBG), in NR, can support CBG's transmission mode, namely, through cutting apart into a plurality of CBG with a TB and transmitting, if receiving terminal demodulation makes mistakes, only need retransmission make mistakes CBG can, need not retransmit whole TB to the cost of retransmission has significantly reduced. Because the current DCI for scheduling the uplink PUSCH does not support the indication of the RV version for each CBG, but only supports the indication of one RV, the RV versions of all retransmitted CBGs are the same for CBG retransmission. Since NR-U evolved from NR, NR-U also supports the transmission characteristics of CBG.

Fig. 3 is a schematic diagram of wideband operation of upstream transmission. As shown in fig. 3, if the bandwidth allocated by the network device when scheduling the terminal device to perform uplink data transmission exceeds the LBT bandwidth (20 MHz), the terminal device may perform LBT on multiple bandwidths of 20MHz by using 20MHz as a unit. Illustratively, the network device sends uplink Grant information (UL _ Grant) to the terminal device through a Physical Downlink Control Channel (PDCCH), so that when the terminal device schedules a TB on an uplink BWP (assuming that frequency domain resources of the TB occupy 320 MHz channels), the terminal device may perform LBT on the corresponding 320 MHz channels, respectively. As shown in fig. 3, PUSCH segs #1 to 3 respectively represent different sub data blocks of the same transport block on 320 MHz channels, and PUSCH segs #4 to 6 respectively represent different sub data blocks of another same transport block on 320 MHz channels. The channels occupied by the PUSCH seg #1, the PUSCH seg #2 and the PUSCH seg #3 pass LBT, and then the terminal equipment may transmit uplink data; the channel occupied by PUSCH seg #6 does not pass LBT, even if the channels occupied by USCH seg #4 and PUSCH seg #5 pass LBT, the terminal device cannot send uplink data, and can only wait for rescheduling of the network device, and the terminal device can send uplink data only when LBT on all scheduled channels passes LBT.

Fig. 4 is another schematic diagram of wideband operation of upstream transmissions. As shown in fig. 4, if the network device reschedules the untransmitted CBGs, the terminal device may uplink transmit a new CBG (e.g., RV _ 1) in the RV version because the New Data Indicator (NDI) is the same, but cannot demodulate data according to the new RV version on the premise that the previous RV version exists (e.g., RV _ 0).

Therefore, only when LBT passes through all uplink 20MHz channels, the terminal device may send uplink data, and if one of the channels is interfered, the whole uplink data is sent with a delay, which reduces the communication rate; in addition, when the CBG of the uplink transmission supporting part is sent and the network device reschedules the unsuccessfully sent CBG, the terminal device may send another CBG of the RV version, so that the terminal device cannot demodulate data according to the new RV version when the initial RV version is absent.

In light of the foregoing, the present application provides a technical solution, which can reduce the time delay of uplink data transmission caused by LBT failure.

In the following embodiments, for distinction and without loss of generality, the first device represents a terminal device and the second device represents a network device.

It should be understood that, in the present application, the data block may be a transmission block, a transmission data block, and the three may be equal to each other, and the present application is not limited herein.

Fig. 5 is a schematic diagram of a method 500 for transmitting data according to an embodiment of the present disclosure. As shown in fig. 5, the method includes:

s501, the second device sends first indication information to the first device.

For example, the second device may transmit first indication information to the first device, the first indication information being used to indicate that the first device transmits the first sub data block over the first PUSCH. Optionally, the first indication information may be carried in DCI.

Specifically, the first device receives first indication information sent by the second device, where the first indication information is used to indicate that the first device sends the first sub data block through the first PUSCH. If the first device receives the first indication information in the first time period, even if the content of the first indication information does not indicate the RV number of the first sub-data block, the first sub-data block and the second sub-data block have the same redundancy version RV number because the first indication information is received in the first time period, the second sub-data block is a sub-data block that fails to be sent through the second PUSCH, and the first sub-data block and the second sub-data block belong to one data block. For example, the first sub data block and the second sub data block may be the same sub data block of the same data block. For example, in one possible implementation manner, fig. 6 is a schematic diagram of a retransmission provided in an embodiment of the present application. As shown in fig. 6, the PUSCH seg #3 with RV of 0 is not successfully transmitted due to LBT failure or the like, and when the PUSCH seg #3 is retransmitted, the version of RV is kept as 0; in another possible implementation manner, fig. 7 is another schematic diagram of a retransmission provided in an embodiment of the present application. As shown in fig. 7, the PUSCH seg #3 with RV of 0 is not successfully transmitted due to LBT failure or the like, and at the time of retransmission, even if the first indication information does not indicate a plurality of RV versions, the PUSCH seg #1 with RV of 1 and the PUSCH seg #3 with RV kept not becoming 0 can be simultaneously transmitted.

If the first device receives the first indication information in a time other than the first time period, the RV number of the first sub-data block is determined according to the first indication information, the RV number of the first sub-data block has no relation with the RV number of the second sub-data block, and the RV number of the first sub-data block is determined by the first device according to the first indication information and is not the same as the RV number of the second sub-data block by default.

Optionally, when the second device detects that the value of the demodulation reference signal of the second channel is smaller than or equal to the preset threshold, the first indication information is sent to the first device.

Specifically, the second device may determine that the terminal device has no data transmission on the second channel according to the value of the demodulation reference signal.

S502, the first device sends the first sub data block to the second device through the first PUSCH.

For example, the first device may transmit the first sub data block to the second device through the first PUSCH after receiving the first indication information. Wherein the first PUSCH is a PUSCH with successful LBT.

It should be understood that, in the above scheme, the contents carried in the first sub data block and the second sub data block are the same, but the configuration parameters of the two sub data blocks may be different, for example, the Modulation and Coding Scheme (MCS) scheduling orders of the two sub data blocks may be different, and in addition, the time-frequency resources for the scheduling signaling transmission of the first sub data block and the second sub data block may also be different, which is not limited herein.

It should also be understood that, in the above scheme, the first PUSCH and the second PUSCH may be the same PUSCH or different PUSCHs, and the present application is not limited herein.

Based on the above scheme, the first device sends the first sub data block through the first PUSCH by receiving the first indication information in the first time period, where the RV number of the first sub data block is the same as that of the second sub data block, where the second sub data block is a sub data block that has failed to be sent due to LBT failure of the second PUSCH and the like in the past, and the same RV number means that the first sub data block and the second sub data block belong to the same data block, and for example, the first sub data block and the second sub data block may be the same sub data block of the same data block. Therefore, on the premise of not modifying DCI, when the second device does not finish demodulating the data block of the previous part, whether the data is successfully transmitted or not is judged according to the energy of the demodulation reference signal of the received uplink data, the sub-data blocks which are not successfully transmitted due to LBT and the like can be directly rescheduled, the waiting time of the first device is reduced, the time delay of uplink transmission is reduced, and the problem that the RV numbers of a plurality of different rescheduled sub-data blocks cannot be flexibly indicated in an uplink reschedule mechanism can be solved. Fig. 8 is a diagram illustrating a method 800 for transmitting data according to an embodiment of the present disclosure. As shown in fig. 8, the method includes:

s801, the second device sends first indication information to the first device.

For example, the second device may send, to the first device, first indication information for indicating that the first device adjusts a first sending position of at least one sub data block of the plurality of data blocks, where any data block of the plurality of data blocks includes at least two sub data blocks.

Specifically, the first device receives first indication information sent by the second device, where the first indication information may schedule multiple data blocks occupying multiple time slots at a time, and adjust a first sending position of at least one sub data block of the multiple data blocks. Optionally, the first indication information may be carried in DCI.

Based on the above scheme, the first device adjusts the first transmission position of at least one sub data block of the multiple data blocks by receiving the first indication information, so that, when the second device schedules the multiple data blocks at a time, the transmission position of the sub data block on the first PUSCH (i.e., the available transmission resource (e.g., LBT successful transmission resource)) can be adjusted, so that the transmission delay of a part of the data blocks is reduced, and the signaling overhead of the rescheduling can be reduced.

The first device adjusts a first sending position of at least one sub data block of the multiple data blocks to obtain a second sending position, wherein the second sending position is an adjusted time-frequency position for sending the at least one sub data block. Specifically, the first device may adjust the first sending position by using the HARQ ID of the at least one sub data block and the corresponding transport channel ID, and obtain the second sending position. Optionally, the first device may adjust the first sending position according to the HARQ ID of the at least one sub data block; when the HARQ IDs of the at least two sub data blocks are the same, the first device adjusts the position adjusted according to the HARQ IDs of the at least two sub data blocks according to the transmission channel IDs corresponding to the at least two sub data blocks, and obtains a second sending position.

For example, fig. 9 is another schematic diagram of a retransmission provided in the embodiment of the present application. As shown in fig. 9 (a), in the multi-TTI transmission mode, when there is a failure in transmission of PUSCH seg #4 with TTI 1, PUSCH seg #4 with TTI 2, or PUSCH seg #4 with TTI 3 due to LBT failure or the like in the shaded PUSCH, the first device may first adjust the transmission position according to the HARQ ID of at least one sub data block in fig. 9 (a). So far, there is no shaded portion, that is, one possible position of the sub data block corresponding to the three PUSCHs with successful LBT is as shown in fig. 9 (b), although the first transmission position is adjusted by the HARQ ID of at least one sub data block, when the HARQ ID is from small to large, the ordering of the partial sub data blocks of the three PUSCHs in one TTI may be out of order, and it cannot be guaranteed that one complete data block is preferentially transmitted. In fig. 9 (b), for example, in TTI _2, the sequence of PUSCH seg #1tti _2and PUSCH seg #2tti _2is not sorted from small to large according to the corresponding transport channel ID, and in TTI _4, the sequence of PUSCH seg #3tti _3and PUSCH seg #4tti _3is not sorted from small to large according to the corresponding transport channel ID, so when the HARQ IDs of at least two sub data blocks in one TTI are the same, the sequence is sorted according to the transport channel IDs corresponding to the at least two sub data blocks to fig. 9 (c). To this end, a second transmission position, i.e., a final transmission position, is obtained. Therefore, on three successful PUSCHs with LBT, the sub-data blocks of the PUSCH seg # 1-4 with TTI 1 can be preferentially sent, the sub-data blocks of the PUSCH seg # 1-4 with TTI 2 can be sent, and the sub-data blocks of the PUSCH seg # 1-4 with TTI 3 can be sent finally, so that the complete data block can be preferentially sent.

It should be understood that, in the above technical solution, the first indication information only indicates that the first device adjusts the first sending position of at least one sub data block of the plurality of data blocks, and is not used to indicate a specific adjustment manner. In a possible implementation, the adjustment may be specifically preconfigured by the first device and the second device.

S802, the first device sends at least one sub data block at a second sending position through a first PUSCH.

Illustratively, the first device, after receiving the first indication information, adjusts a first transmission position of the at least one sub data block and obtains a second transmission position, transmits the at least one sub data block at the second transmission position through the first PUSCH. Wherein the first PUSCH is an LBT successful or available PUSCH.

Based on the above scheme, the first device adjusts the first sending position according to the HARQ ID of at least one sub data block, and on this basis, when the HARQ IDs of at least two sub data blocks are the same, the first device adjusts according to the corresponding transmission channel ID to obtain the second sending position. Thus, a partially complete data block may be transmitted preferentially; in addition, when the network device schedules a plurality of PUSCHs at one time, part of the sub-data blocks are distributed to the successful PUSCH of LBT for transmission, so that the transmission delay of part of the PUSCH is reduced, and the signaling overhead of rescheduling is reduced.

Fig. 10 is a schematic diagram of a method 1000 for transmitting data according to an embodiment of the present application. As shown in fig. 10, the method includes:

s1001, the second device sends first indication information to the first device.

For example, the second device may transmit first indication information to the first device, the first indication information indicating a duration of the first period. Optionally, the first indication information may be carried in RRC signaling.

Specifically, the first device may obtain the information of the duration of the first period by receiving the first indication information sent by the second device. Alternatively, the duration of the first period may be the shortest time for the second device to completely demodulate two sub-data blocks.

S1002, the first device determines a first time period.

Illustratively, after receiving the first indication information, the first device obtains information of a duration of a first time period, and may determine the first time period, where a starting time of the first time period is a time when the second sub data block is scheduled to be transmitted.

And S1003, the second equipment sends second indication information to the first equipment.

For example, the second device may transmit second indication information to the first device, the second indication information indicating that the first sub data block is transmitted over the first PUSCH.

For example, the second device may transmit second indication information to the first device, the second indication information indicating that the first device transmits the first sub data block over the first PUSCH. Optionally, the second indication information may be carried in DCI.

Specifically, regarding the description of the relationship between the first sub data block and the second sub data block, reference may be made to the description regarding the first sub data block and the second sub data block in S501; the first device receives the second indication information in the first period or receives the description of the second indication information at the time other than the first period, which may refer to the description in S501 about the first device receiving the first indication information in the first period or receiving the first indication information at the time other than the first period, and is not described herein again.

S1004, the first device sends the first sub data block to the second device through the first PUSCH.

For example, the first device may transmit the first sub data block to the second device through the first PUSCH after receiving the second indication information. Wherein, the first PUSCH is a PUSCH with successful LBT.

Specifically, fig. 9 is another schematic diagram of a retransmission provided in an embodiment of the present application. As shown in fig. 9 (a), the first PUSCH may be the first two PUSCHs without hatching, and the second PUSCH is a PUSCH containing hatching, i.e., a PUSCH with LBT failure. In the transmission of TTI _2, the first device may transmit the PUSCH seg #1 with RV version number 1 and, at the same time, the PUSCH seg #4 with RV version number 0.

It should be understood that, in the foregoing solution, the contents of the first sub data block and the second sub data block are the same, but other parameters may be different, for example, the order of MCS scheduling may be different, and the scheduled time-frequency resources of the first sub data block and the second sub data block may also be different, which is not limited herein.

It should also be understood that, in the above scheme, the first PUSCH and the second PUSCH may be the same PUSCH or different PUSCHs, and the application is not limited herein.

Based on the above scheme, the first device sends the first sub data block through the first PUSCH by receiving the second indication information in the first period, where RV numbers of the first sub data block and the second sub data block are the same, where the second sub data block is a sub data block that has been sent unsuccessfully due to LBT failure of the second PUSCH and the like, and the first sub data block and the second sub data block may belong to the same data block, and for example, the first sub data block and the second sub data block may be the same sub data block of the same data block. Therefore, on the premise of not modifying DCI, when the second device does not finish demodulating the data block of the previous part, whether the data is successfully transmitted or not is judged according to the energy of the demodulation reference signal of the received uplink data, the sub-data blocks which are not successfully transmitted due to LBT and the like can be directly rescheduled, the waiting time of the first device is reduced, the time delay of uplink transmission is reduced, and the problem that the RV numbers of a plurality of different rescheduled sub-data blocks cannot be flexibly indicated in an uplink reschedule mechanism can be solved.

S1005, the second device sends the third indication information to the first device.

For example, the second device may transmit, to the first device, third indication information indicating that a first transmission position of at least one sub data block of the plurality of data blocks is adjusted, where any one of the plurality of data blocks includes at least two sub data blocks.

Specifically, for the description of the third indication information, reference may be made to the description of the first indication information in S801, and details are not repeated here for brevity.

S1006, the first device adjusts the first sending position according to the HARQ ID of the at least one sub-data block and the corresponding transmission channel ID.

For example, the first device may adjust the first transmission position according to the HARQ ID of at least one sub data block of the plurality of data blocks and the corresponding transport channel ID after receiving the third indication information.

Specifically, for the description that the first device adjusts the first sending position according to the HARQ ID of the at least one sub data block and the corresponding transmission channel ID to obtain the second sending position, reference may be made to the description in S801 that the first device adjusts the first sending position according to the HARQ ID of the at least one sub data block and the corresponding transmission channel ID to obtain the second sending position, and for brevity, this application is not described herein again.

It should be understood that, in the above technical solution, the third indication information only indicates that the first device adjusts the first sending position of at least one sub data block of the plurality of data blocks, and is not used to indicate a specific adjustment manner. In a possible implementation, the adjustment may be specifically preconfigured by the first device and the second device.

S1007, the first device sends the at least one sub data block in the second sending location to the second device through the third PUSCH.

For example, the first device may transmit the at least one sub data block at the second transmission position to the second device through the third PUSCH after adjusting the first transmission position of the at least one sub data block to the second transmission position. Wherein the third PUSCH is an LBT successful or available PUSCH. As shown in fig. 11, the third PUSCH may be a PUSCH without a shaded portion, and the position of the sub data block of TTI _3 to TTI _5 in fig. 11 (a) is the first transmission position, and after adjustment, the position of the sub data block of TTI _3 to TTI _5 in fig. 11 (b), that is, the second transmission position, may be obtained.

Based on the above scheme, the first device first adjusts the first sending position according to the HARQ ID of at least one sub data block, and on this basis, when the HARQ IDs of at least two sub data blocks are the same, the first device adjusts according to the corresponding transmission channel ID to obtain the second sending position. Thus, a partially complete data block may be transmitted preferentially; in addition, when the network device schedules a plurality of PUSCHs at one time, part of the sub-data blocks are distributed to the successful PUSCH of LBT for transmission, so that the transmission delay of part of the PUSCH is reduced, and the problem that all uplink data blocks need to be rescheduled due to the problem of LBT failure of some PUSCHs is solved.

It should be understood that in the method 1000 for transmitting data, S1001 to S1004 may precede S1005 to S1007, and as another example, S1001 to S1004 may also follow S1005 to S1007, which is not limited herein.
