Optionally, the communication system 100 may further include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiments of the present application.

It should be understood that the devices with communication functions in the network / system in the embodiments of the present application may be referred to as communication devices. Taking the communication system 100 shown in FIG. 1 as an example, the communication device may include a network device 110 and a terminal device 120 with a communication function, and the network device 110 and the terminal device 120 may be the specific devices described above, which will not be repeated here. The communication device may also include other devices in the communication system 100, such as network controllers, mobility management entities, and other network entities, which are not limited in the embodiments of the present application.

The term "and / or" in this article is just an association relationship that describes an associated object, indicating that there can be three relationships, for example, A and / or B, which can mean: A exists alone, A and B exist at the same time, exist alone B these three cases. In addition, the character "/" in this article generally indicates that the related objects before and after are in an "or" relationship.

In this communication system, if the terminal device reports NACK for a certain downlink data in the report of Acknowledgement (ACK) / Negative Acknowledgement (NACK), or if the network device does not detect the uplink data, the network The device needs to schedule the retransmission of the data through DCI, and the retransmission and initial transmission can use the same HARQ process.

Moreover, in this communication system, the network device can schedule different transmission points (Transmission / Reception Point, TRP) to transmit the same data at the same time, and the transmission reliability is improved by repeatedly sending the same data. Because the data transmitted by different TRPs is the same, the same HARQ process can also be used. In this case, for the terminal device, it is impossible to distinguish that the data in the same HARQ process scheduled by the network device through two DCIs is a repetition of the same data The transmission is still two different data (that is, the latter data is a new data schedule). Therefore, the terminal device cannot combine the data scheduled by the two DCIs, which affects the transmission performance.

In view of this, the embodiments of the present application provide a data transmission method. The terminal device may determine the relationship between the data channels scheduled by the two DCIs according to the transmission resources of the two DCIs sent by the network device, so as to The data channels scheduled by the two DCIs are processed accordingly.

Optionally, in some embodiments, the data channels scheduled by the first DCI and the second DCI both carry new data transmission. That is, the data carried in the data channels scheduled by the first DCI and the second DCI are both transmitted for the first time rather than retransmitted.

Specifically, the DCI may include new data (New Data Indicator, NDI) indication information, used to indicate whether the data channel scheduled by the DCI is used to carry new data.

For example, the DCI may include 1-bit NDI indication information, and different values of the 1-bit NDI indication information are used for whether the data channel scheduled by the DCI is used to carry new data or retransmit data, for example, the 1-bit NDI indication When the information is set to 1, it indicates new data, and when it is set to 0, data is retransmitted. In this embodiment of the present application, the value of the NDI indication information included in the first DCI and the second DCI may both be 1, indicating that the data channel scheduled by the DCI is used to carry new data transmission.

Optionally, the first threshold may be N time slots, or M symbols, etc., where N and M are positive integers.

Optionally, the first threshold may be preset on the terminal device, for example, the first threshold specified in the protocol may be preset on the terminal device; or the first threshold may also be configured by the network device For example, the network device can configure the terminal device through high-layer signaling, such as radio resource control (Radio Resource Control, RRC) signaling, or physical layer signaling, such as physical downlink control channel (Physical Downlink Control Channel, PDCCH).

As another optional embodiment of the first embodiment, the terminal device may determine whether the time units of detecting the first DCI and the second DCI are the same time unit to determine the bearers in the first data channel and the second data channel Whether the data is the same.

For example, the terminal device may determine that the data carried in the first data channel and the second data channel are the same when the time unit detecting the first DCI and the second DCI are the same time unit, otherwise, determining the first data The data carried in the channel and the second data channel are different.

It can be understood that adjacent or similar DCIs are more likely to schedule the same data. When the time interval between the two DCIs is shorter, the terminal device determines that the data scheduled by the two DCIs are the same. The data is combined for processing, for example, combined demodulation or combined feedback, so as to save transmission resources and improve transmission performance.

As yet another optional embodiment of Embodiment 1, the terminal device may determine the data carried in the first data channel and the second data channel according to the CORESET and / or search space where the first DCI and the second DCI are located Is it the same?

For another example, the terminal device may determine that the data carried in the first data channel and the second data channel are different when the first DCI and the second DCI are transmitted in the same search space, otherwise, determine the first data channel and The data carried in the second data channel is the same.

In Embodiment 2, the terminal device may determine whether the spatial transmission filters used by the first data channel and the second data channel are the same according to the time interval between the first DCI and the second DCI .

For example, when the time interval between detecting the first DCI and detecting the second DCI is less than or equal to the second threshold, the terminal device may determine the spatial filtering used by the spatial transmission filter used by the first data channel and the second data channel It is the same; when the time interval between detecting the first DCI and detecting the second DCI is greater than the second threshold, it is determined that the spatial transmission filter used by the first data channel and the second data channel is different in spatial filter.

It should be understood that for the specific implementation of the second threshold, reference may be made to the specific implementation of the first threshold in Embodiment 1, and details are not described herein again.

In Embodiment 3, the terminal device may be based on the time interval between the first DCI and the second DCI, or the control resource set CORESET where the first DCI and the second DCI are located, or the The search space where the first DCI and the second DCI are located determines whether the determination / negation of the first data channel and the second data channel determines whether ACK / NACK feedback information is reported together. Specifically, the ACK / NACK feedback information of the two data channels here can be reported together through the same physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) resource. Correspondingly, the ACK / NACK feedback of the two data channels Not reporting the information together may refer to reporting corresponding ACK / NACK separately through different PUSCH resources.

As an optional embodiment of Embodiment 3, the terminal device may determine the first data channel and the second data channel when the time interval between detecting the first DCI and detecting the second DCI is less than or equal to a third threshold ACK / NACK feedback information is reported together, or when the time interval between detecting the first DCI and detecting the second DCI is greater than a third threshold, it is determined that the ACK / NACK feedback information of the first data channel and the second data channel are not together Escalate.

As another optional embodiment of Embodiment 3, the terminal device may determine the time unit of the first data channel and the second data channel when the time unit for detecting the first DCI and the second DCI are the same time unit ACK / NACK feedback information is reported together, or, when the time units for detecting the first DCI and the second DCI are different time units, it is determined that the ACK / NACK feedback information for the first data channel and the second data channel are not together Escalate.

As a further optional embodiment of this embodiment 3, the terminal device may determine the first data channel and the second data channel when the CORESET where the first DCI and the second DCI are located is the same CORESET The ACK / NACK feedback information is reported together, otherwise, it is determined that the ACK / NACK feedback information of the first data channel and the second data channel are not reported together.

Alternatively, in other optional embodiments, the terminal device may determine ACK / NACK feedback information of the first data channel and the second data channel when the first DCI and the second DCI are in the same search space Report together, otherwise, it is determined that the ACK / NACK feedback information of the first data channel and the second data channel are not reported together.

It should be understood that for the specific implementation of the third threshold, reference may be made to the specific implementation of the first threshold in Embodiment 1, and details are not described herein again.

In Embodiment 4, the terminal device may determine whether the first data channel and the second data channel are fed back through the same ACK / NACK according to the time interval between the first DCI and the second DCI Information is reported to ACK / NACK.

As an optional embodiment of this embodiment 4, the terminal device may determine the first data channel and the second data channel when the time interval between detecting the first DCI and detecting the second DCI is less than or equal to a fourth threshold ACK / NACK is reported through the same ACK / NACK feedback information, or when the time interval between detecting the first DCI and the second DCI is greater than the fourth threshold, determining the ACK / NACK of the first data channel and the second data channel Not reported through the same ACK / NACK feedback information.

Specifically, here the ACK / NACK of the two data channels is reported through the same ACK / NACK feedback information, which refers to that only one ACK / NACK information is reported for the two data channels. For example, if one of the data channels is demodulated correctly, ACK can be reported; otherwise, NACK can be reported.

Correspondingly, the ACK / NACK of the two data channels is not reported through the same ACK / NACK feedback information, and a pointer can be used to report one ACK / NACK information to the two data channels respectively. For example, if the first data channel is correctly demodulated, ACK can be reported for the first data channel, otherwise NACK is reported, and the same is true for the second data channel.

It should be understood that for the specific implementation of the fourth threshold, reference may be made to the specific implementation of the first threshold in Embodiment 1, and details are not described herein again.

It should be noted that the above Embodiments 1 to 4 can be implemented individually or in combination. The specific embodiments in a single embodiment can be implemented separately or in combination, which is not limited in the embodiments of this application, for example , The terminal device may determine the first DCI when the time interval between detecting the first DCI and the second DCI is less than or equal to the first threshold, and the first DCI and the second DCI are transmitted in different CORESET or search spaces The data carried in the data channel and the second data channel are the same; otherwise, it is determined that the data carried in the first data channel and the second data channel are different.

Optionally, in the embodiment of the present application, the first data channel scheduled by the first DCI may be an uplink data channel, for example, PUSCH, or may be a downlink data channel, for example, a physical downlink shared channel (Physical Downlink Shared Channel) Shared (Channel, PDSCH), etc.

Similarly, the second data channel scheduled by the second DCI may also be an uplink data channel, such as PUSCH, or a downlink data channel, such as PDSCH.

It should be understood that, for the specific process of determining that the data carried in the first data channel and the second data channel are the same, reference may be made to the related description of Embodiment 1.

In this case, the terminal device may perform combined demodulation on the first data channel and the second data channel, so as to increase the probability of successful demodulation, thereby improving transmission performance.

Further, when reporting the feedback information, the terminal device may report only one piece of feedback information, such as ACK or NACK, for the first data channel and the second data channel, thereby reducing feedback overhead. Optionally, the terminal device may transmit the feedback information according to the control information in the DCI that was recently received in the first DCI and the second DCI.

Specifically, if the terminal device correctly detects at least one of the first data channel and the second data channel, the terminal device may report an ACK, or, if the terminal device does not correctly detect the first data Any one of the channel and the second data channel, the terminal device may report NACK.

Case 2: Both the first data channel and the second data channel are downlink data channels, and the data carried in the first data channel and the second data channel are different.

In this case, the terminal device may separately demodulate the first data channel and the second data channel, and further report the ACK / NACK corresponding to each data channel.

Case 3: Both the first data channel and the second data channel are uplink data channels, and the data carried in the first data channel and the second data channel are the same.

In this case, the terminal device can generate the same data and transmit it through the first data channel and the second data channel, respectively.

At this time, when generating the data in the second data channel, the terminal device may obtain the data in the second data channel according to the data in the first data channel.

Optionally, the terminal device may use different antenna panels to send the first data channel and the second data channel, which is beneficial to ensure the reliability of data transmission and thereby improve data transmission performance.

Case 4: Both the first data channel and the second data channel are uplink data channels, and the data carried in the first data channel and the second data channel are different.

In this case, the terminal device can generate different data and transmit them through the first data channel and the second data channel, respectively.

At this time, the terminal device may generate new data when generating data in the second data channel.

Optionally, the terminal device may use different or the same antenna panel to send the first data channel and the second data channel.

It should be understood that, in addition to the above four cases, one of the first data channel and the second data channel may be an uplink data channel and the other is a downlink data channel. In this case, the terminal device only needs to The data carried in the first data channel and the second data channel can be processed separately, which will not be repeated here.

Optionally, in the embodiment of the present application, if the data carried in the first data channel and the second data channel are the same, the terminal device adopts different configurations, for example, modulation and coding scheme (Modulation and Coding Scheme, MCS), At least one of the physical layer resource configuration and the beam transmits or receives the first data channel and the second data channel, so that the reliability of data transmission can be improved.

For example, the time domain resource configuration may be a resource mapping type, and the frequency domain resource configuration may be a physical resource block (Physical Resource Block, PRB) occupied by a data channel.

Therefore, according to the data transmission method of the embodiment of the present application, the terminal device can determine whether the data channels scheduled by the multiple DCIs carry the same data according to the transmission resources of the multiple DCIs, so that the terminal device can carry the same data In this case, the same data is combined, for example, combined demodulation or combined feedback, so as to improve data transmission performance.
