In order to more clearly understand the present application, a specific implementation of the embodiments of the present application is described below, and the following description is applicable to the

above methods

200 and 300, or may also be applicable to the following

methods

400 and 500.

Optionally, in this embodiment of the present application, for a terminal device, the transmission of first to-be-transmitted information on the first transmission resource is stopped, and/or the transmission of second to-be-transmitted information on a second transmission resource that is not the first transmission resource may have the following multiple implementation manners.

In one implementation, on the first transmission resource, transmission of the first information to be transmitted is stopped, and the second information to be transmitted is not transmitted on the second transmission resource.

In another implementation, on the first transmission resource, transmission of the first information to be transmitted and transmission of the second information to be transmitted on the second transmission resource are stopped.

In another implementation, on the first transmission resource, transmission of the first information to be transmitted and transmission of the second information to be transmitted on the second transmission resource are not stopped.

Similarly, in this embodiment of the present application, for a network device, the following multiple implementation manners may be provided for stopping obtaining first to-be-transmitted information on the first transmission resource, and/or obtaining second to-be-transmitted information on a second transmission resource that is not the first transmission resource.

In one implementation, on the first transmission resource, the acquisition of the first information to be transmitted is stopped, and the acquisition of the second information to be transmitted is not performed on the second transmission resource.

In another implementation, on the first transmission resource, the acquisition of the first information to be transmitted is stopped and the acquisition of the second information to be transmitted on the second transmission resource is stopped.

In another implementation, the acquisition of the first information to be transmitted and the acquisition of the second information to be transmitted on the second transmission resource are not stopped on the first transmission resource.

Optionally, the configuration signaling in this embodiment may be DCI, or may also be a higher layer signaling, or may also be other signaling, which is not specifically limited in this embodiment.

Optionally, in this embodiment of the present application, the DCI may trigger the terminal device to stop transmitting the first to-be-transmitted information on the first transmission resource in a manner of carrying the first HARQ process number, and/or transmit the second to-be-transmitted information on a second transmission resource that is not the first transmission resource, and may also be used for data scheduling, for example, scheduling uplink data transmission or scheduling downlink data transmission.

When the DCI schedules downlink data transmission, the scheduled downlink data may have the same first HARQ process number as the first downlink data, and the scheduled downlink data may be different from or the same as the first downlink data (for example, may be different from the TB, that is, different from the original information).

Of course, the HARQ process number of the downlink data scheduled by the DCI may not be the first HARQ process number.

At this time, the DCI may include two HARQ process numbers, where one HARQ process number is a first HARQ process number, and the other HARQ process number is an HARQ process number of downlink data scheduled by the DCI.

Optionally, in this embodiment of the present application, the DCI may not be used for scheduling data.

Wherein, it may be implemented that a specific information field in the DCI is set as a default value, for example, the frequency domain resource allocation information field indicates a specific value (e.g., all 0), the time domain resource allocation information field indicates a specific value (e.g., all 0), and the like, so as to implement that the DCI does not schedule a Physical Downlink Shared Channel (PDSCH)

Optionally, the first transmission resource in this embodiment may be indicated by the configuration signaling, or may be determined by a preset rule, or may be indicated by configuration signaling for scheduling other data.

For example, a certain configuration signaling is used to schedule downlink data different from the first downlink data, the configuration signaling indicates a first transmission resource, and the first transmission resource may be used to transmit the first downlink data and feedback information of the downlink data different from the first downlink data.

Optionally, the feedback information (e.g., the first feedback information, the second feedback information, and the third feedback information) in the embodiment of the present application may be HARQ-Acknowledgement (ACK) feedback information, and specifically may be ACK information and (Negative Acknowledgement (NACK) information.

Optionally, the information to be transmitted (e.g., the first information to be transmitted and the second information to be transmitted) in the embodiment of the present application may be a feedback sequence including at least one feedback information.

Optionally, in this embodiment of the present application, for the terminal device, stopping transmission of the first to-be-transmitted information on the first transmission resource may be understood as the following multiple situations.

In one case, the first information to be transmitted is already prepared but not yet transmitted when the DCI is received, at which point the terminal device may stop preparing the first information to be transmitted and the terminal device does not transmit the first information to be transmitted.

In one case, when receiving the DCI, the first information to be transmitted is already prepared or is already prepared but is not yet transmitted, and at this time, the terminal device may not transmit the first information to be transmitted.

In one case, when receiving the DCI, the first to-be-transmitted information has started to be transmitted but has not been transmitted, and at this time, the terminal device may stop transmitting the first transmission information.

In one case, when receiving the DCI, the first to-be-transmitted information is already sent, and at this time, the terminal device may consider that the sending of the first transmission information is an invalid transmission, that is, the terminal device does not expect the network device to receive or demodulate the sent first transmission information.

Optionally, in this embodiment, for the network device, when it is determined that the DCI needs to be sent, that is, on the first transmission resource, the network device may stop acquiring the first information to be transmitted.

In one case, when it is determined that the DCI needs to be transmitted, if the reception operation of the first information to be transmitted has not been started, the reception operation of the first information to be transmitted is not performed any more.

In one case, when it is determined that the DCI needs to be transmitted, if the reception operation of the first information to be transmitted has already been started but has not been completed, the reception of the first information to be transmitted is stopped.

In one case, when it is determined that the DCI needs to be transmitted, if the first information to be transmitted has been received and is not demodulated, the first information to be transmitted may not be demodulated.

In one case, when it is determined that the DCI is required to be transmitted, if the first information to be transmitted has been demodulated but has not been demodulated completely, the demodulation of the first information to be transmitted may be stopped.

It should be understood that, although it is described above that the acquisition of the first information to be transmitted is stopped when it is determined that the DCI needs to be transmitted, the embodiment of the present application is not limited to this, and for example, the network device may stop acquiring the first information to be transmitted starting at a time when the transmission of the DCI is completed, or the network device may stop acquiring the first information to be transmitted starting at a time when the terminal device has successfully demodulated the DCI.

Optionally, in this embodiment of the present application, the sending time of the configuration signaling may be earlier than the DCI signaling. At this time, optionally, the terminal device may determine, based on the obtained time relationship between the DCI signaling and the configuration signaling and the process number carried in the DCI signaling, that the first to-be-transmitted information needs to be obtained on the first transmission resource, and/or obtain the second to-be-transmitted information on a second transmission resource that is not the first transmission resource.

Or, the DCI signaling may have a specific information field indicating that the DCI is used to trigger the terminal device to stop acquiring the first information to be transmitted on the first transmission resource and/or acquire the second information to be transmitted on a second transmission resource that is not the first transmission resource.

Wherein, the sending time of the configuration signaling is earlier than that of the DCI signaling, and can be understood as:

the sending start time of the configuration signaling is earlier than the sending start time of the DCI, and the sending end time of the configuration signaling may be equal to or earlier than or later than the sending end time of the DCI; or the like, or, alternatively,

the sending end time of the configuration signaling is earlier than the sending end time of the DCI, and the sending start time of the configuration signaling can be equal to or earlier than or later than the sending start time of the DCI; or the like, or, alternatively,

the sending starting time of the configuration signaling is earlier than the sending starting time of the DCI, and the sending ending time of the configuration signaling is earlier than the sending ending time of the DCI;

the transmission ending time of the configuration signaling is earlier than the transmission starting time of the DCI.

Optionally, in this embodiment of the present application, a time interval between the sending time of the DCI and the sending time of the configuration signaling is not less than a first preset time.

Optionally, in this embodiment of the present application, a time interval between the sending time of the DCI and the sending time of the configuration signaling is not greater than a second preset time.

That is, the DCI is transmitted later than the configuration signaling by a time at least equal to the first preset duration and further not greater than the second preset duration. However, the embodiment of the present application is not limited to this, and the time interval between the sending time of the DCI and the sending time of the configuration signaling may also be smaller than a first preset time length or larger than a second preset time length.

Here, the time interval mentioned here may be an interval between a transmission start time of the configuration signaling and a transmission start time of the DCI signaling, or an interval between a transmission end time of the configuration signaling and a transmission end time of the DCI signaling, or an interval between a transmission end time of the configuration signaling and a transmission start time of the DCI signaling, or an interval between a transmission start time of the configuration signaling and a transmission end time of the DCI signaling.

Of course, in the embodiment of the present application, the sending time of the configuration signaling may also be later than or equal to the DCI signaling.

Optionally, in this embodiment of the present application, the sending time of the DCI is located before the time domain resource of the first transmission resource.

Specifically, if the DCI is used to trigger the terminal device to stop transmitting the first information to be transmitted including the first feedback information on the first transmission resource, the DCI needs to be sent before the time domain resource of the first transmission resource, otherwise, the DCI is sent after the time domain resource, and the DCI does not trigger the terminal device to stop transmitting the first information to be transmitted on the first transmission resource.

Optionally, in this embodiment of the present application, an interval between the sending end time of the DCI and the start time of the time domain resource of the first transmission resource is not less than a third preset time.

Specifically, the terminal device needs to perform processing (for example, demodulate DCI) after receiving the DCI, and needs to predetermine a certain processing delay, so that an interval between the sending end time of the DCI and the start time of the time domain resource of the first transmission resource is not less than a third preset time length, which may ensure that transmission of the first to-be-transmitted information on the first transmission resource is stopped.

Optionally, in this embodiment of the application, the terminal device may be implemented in any one of the following manners (1) to (3) to stop transmitting the first to-be-transmitted information on the first transmission resource.

(1) And stopping sending the uplink channel carrying the first information to be transmitted on the first uplink transmission resource.

Specifically, sending of the uplink channel may be stopped on the first uplink transmission resource, where the uplink channel is used to carry the first information to be transmitted, so that transmission of the first information to be transmitted may be stopped. The Uplink Channel may be a Physical Uplink Shared Channel (PUSCH) or a Physical Uplink Control Channel (PUCCH).

(2) And the first information to be transmitted is not included in the uplink channel on the first uplink transmission resource.

Specifically, the uplink channel sent on the first uplink transmission resource may be used to carry the first information to be transmitted, and in order to stop transmitting the first information to be transmitted, the first information to be transmitted may not be included in the uplink channel, but the uplink channel is still sent. The uplink channel may be a PUCCH or a PUSCH, so that normal transmission of other information in the channel can be guaranteed while transmission of the first information to be transmitted is stopped.

(3) And transmitting the occupancy information in an uplink channel carrying the first information to be transmitted on the first uplink transmission resource.

Specifically, the uplink channel sent on the first uplink transmission resource may be used to carry the first information to be transmitted, and in order to stop transmitting the first information to be transmitted, the uplink channel may not include the first information to be transmitted but send the placeholder information, but still send the uplink channel. The uplink channel may be a PUCCH or a PUSCH, so that normal transmission of other information in the channel can be guaranteed while transmission of the first information to be transmitted is stopped.

Accordingly, for the terminal device, the following may be implemented to stop obtaining the first to-be-transmitted information on the first transmission resource:

on the first uplink transmission resource, stopping acquiring the uplink channel carrying the first information to be transmitted; or the like, or, alternatively,

stopping acquiring the first information to be transmitted in an uplink channel on the first uplink transmission resource; or

And acquiring occupancy information in an uplink channel carrying the first information to be transmitted on the first uplink transmission resource.

Optionally, in this embodiment of the application, the first information to be transmitted may further include second feedback information, where the second feedback information is feedback information of second downlink data that is not the first downlink data or the second feedback information is occupancy information, and the transmission resource of the second feedback information includes the first transmission resource. Specifically, on the first transmission resource, the first information to be transmitted that needs to be sent includes multiple pieces of feedback information, and if the DCI received by the terminal carries the first HARQ process number, transmission of the first information to be transmitted may be stopped, or transmission of the first feedback information may also be stopped, and the first transmission resource also needs to send second feedback information corresponding to the second downlink data, at this time, transmission of the second feedback information may also be stopped, where the HARQ process number of the second downlink data may be different from the HARQ process number of the first downlink data, and the DCI may not carry the HARQ process number of the second downlink data. Of course, the HARQ process number of the second downlink data may also be the same as the HARQ process number of the first downlink data.

Or, in this embodiment of the application, even if the first transmission resource needs to send the second feedback information of the second downlink data, the first information to be transmitted may not include the second feedback information, that is, it is not necessary to stop sending the second feedback information on the first transmission resource. At this time, the uplink channel may be sent on the first transmission resource, where the uplink channel does not include the first feedback information or sends the occupancy information, and the uplink channel includes the second feedback information.

Optionally, in this embodiment of the application, the second to-be-transmitted information sent on the second transmission resource may further include third feedback information, where the third feedback information may be feedback information of third downlink data scheduled in the DCI.

Specifically, the DCI may also schedule third downlink data, and then the third feedback information may be sent at the same time as the first feedback information is sent on the third transmission resource.

Optionally, in this embodiment of the application, the second information to be transmitted may also include the second feedback information.

Optionally, if the first information to be transmitted includes the second feedback information, the second information to be transmitted also includes the second feedback information. If the first information to be transmitted does not include the second feedback information, the second information to be transmitted also does not include the second feedback information.

In order to more clearly understand the present application, the following detailed description will be made on embodiments of the present application with reference to fig. 4 to 7.

For example, as shown in fig. 4, DCI1 is used to schedule PDSCH1 of HARQ process X, DCI2 carries the process number of HARQ process X, and the feedback resource of PDSCH1 is resource 1, the terminal device may not transmit ACK/NACK (a/N) of PDSCH1 on resource 1, where DCI2 may also schedule PDSCH2, and may transmit ACK/NACK (a/N) of PDSCH2 on resource 2 and may further transmit feedback information of PDSCH1 on resource 2.

For example, as shown in fig. 5, three DCIs respectively schedule three PDSCHs, HARQ processes of the three PDSCHs are respectively HARQ process X, HARQ process Y and HARQ process Z, ACK/NACK (a/N) information of the three PDSCHs is multiplexed and transmitted through one uplink channel, a transmission resource is resource 1, and if the HARQ process number in the DCI2 is the same as any one of the three PDSCHs, transmission of the uplink channel carrying the ACK/NACK is stopped in resource 1. At this time, DCI2 may schedule one valid PDSCH4 transmission and indicate one new uplink channel resource, i.e., resource 2, to transmit ACK/NACK, where the ACK/NACK transmitted in the new uplink channel may include ACK/NACK information corresponding to at least some of the three PDSCHs and may include ACK/NACK information corresponding to PDSCH 4.

For example, as shown in fig. 6, three DCIs respectively schedule three PDSCHs, HARQ processes of the three PDSCHs are respectively HARQ process X, HARQ process Y and HARQ process Z, ACK/NACK information of the three PDSCHs is multiplexed and transmitted through one uplink channel, a transmission resource is resource 1, and the HARQ process number in the DCI2 is the same as any one of the three PDSCHs, so that transmission of the uplink channel carrying the ACK/NACK is stopped in resource 1. In this case, the transmission DCI2 is used to instruct the uplink channel to stop transmission without expecting a new PDSCH, and ACK/NACK information corresponding to the three PDSCHs is transmitted using a new uplink channel resource, that is, resource 2.

Wherein the DCI may not schedule the PDSCH by setting a specific information field in the DCI to a predetermined value.

For example, as shown in fig. 7, three DCIs respectively schedule three PDSCHs, HARQ processes of the three PDSCHs are HARQ process X, HARQ process Y and HARQ process Z, ACK/NACK information of the three PDSCHs are multiplexed and transmitted through one uplink channel, the transmission resource is resource 1, and the DC2 may indicate that an additional uplink channel (carried in resource 2) is used for carrying feedback information of HARQ process X, HARQ process Y and/or HARQ process Z.

The scheme shown in fig. 7 is similar to the scheme shown in fig. 6, with the difference that the scheme shown in fig. 6 requires stopping transmitting the uplink channel corresponding to DCI1, and the scheme shown in fig. 6 does not require stopping the previous transmission, and whether the stopping may depend on a specific implementation algorithm of the terminal, but the terminal must transmit the ACK/NACK information before transmitting on the newly indicated resource. As shown in fig. 7, if the DCI2 transmission time is close to or even overlaps with the ACK/NACK transmission time instructed before, the terminal cannot cancel the previous transmission operation, but must retransmit the DCI2 transmission time.

Optionally, in this embodiment of the application, the step of interrupting transmission of the first data may be understood as suspending transmission of the first data, and then continuing transmission of the first data, where the interrupted transmission of the first data may be transmission of a configuration based on the configuration signaling.

Whether to continue transmission of the first data may be instructed by the network device, or may be determined by the terminal device, for example, if the DCI is used to schedule new data, the network device may continue transmission of the first data after the new data is completely transmitted.

Alternatively, in this embodiment of the application, stopping transmission of the first data may be understood as that transmission of the first data is not performed any more subsequently, and the stopped transmission of the first data may be transmission of the first data based on configuration of the configuration signaling.

Optionally, in this embodiment of the present application, the DCI may also be used to schedule the second data.

The HARQ process number of the second data may be the same as the HARQ process number of the first data.

In the case that the HARQ process numbers are the same, the second data may or may not be equal to the first data.

Of course, the HARQ process number of the downlink data scheduled by the DCI may also be different from the first HARQ process number.

At this time, the DCI may include two HARQ process numbers, where one HARQ process number is an HARQ process of the first data and is used to indicate to reset, interrupt, or stop transmission of the first data, and the other HARQ process number is an HARQ process number of the second data scheduled by the DCI.

Optionally, in this embodiment of the present application, the starting point of the time window may include the following (1) or (2).

(1) And the sending time of the configuration signaling.

It is to be understood that the above possible implementations of the start point of the time window and the possible implementations of the end point of the time window may be combined in any combination, in case it is guaranteed that the end point of the time window is later than the start point of the time window.

Optionally, the starting point and the ending point of the time window in the embodiment of the present application may be preset on the terminal device, or may be configured on the network side.

interrupting or stopping receiving the physical downlink shared channel bearing the first data; or the like, or, alternatively,

and interrupting or stopping demodulating the physical downlink shared channel carrying the first data.

Specifically, if the terminal device has not received the first data or has not received the first data completely, the receiving of the physical downlink shared channel carrying the first data may be interrupted or stopped. Or, if the terminal device has already received the physical downlink shared channel that has finished carrying the first data, the demodulation of the physical downlink shared channel that carries the first data may be interrupted or stopped.

Accordingly, interrupting or stopping transmission of the first data for a network device includes:

interrupting or stopping sending the physical downlink shared channel bearing the first data; or the like, or, alternatively,

and interrupting or stopping preparing a physical downlink shared channel carrying the first data.

Specifically, if the network device has not sent the first data, the preparation of the physical downlink shared channel carrying the first data is interrupted or stopped. And if the network equipment has not sent the first data, interrupting or stopping sending the physical downlink shared channel carrying the first data.

Optionally, in this embodiment of the application, when the first data is downlink data, the DCI may be downlink grant DCI, and a format (format) of the DCI is DCI format 1_0 or DCI format _1, or may be another DCI format.

For the case that the first data is downlink data, if the transmission of the first data is stopped or interrupted, the feedback information of the first data may not need to be sent.

Optionally, in this embodiment of the present application, for a terminal device, when the first data is uplink data, interrupting or stopping the first data includes:

interrupting or stopping preparing a physical uplink shared channel carrying the first data; or the like, or, alternatively,

and interrupting or stopping sending the physical uplink shared channel carrying the first data.

Specifically, if the terminal device is preparing or has not prepared a physical uplink shared channel carrying the first data, the physical uplink shared channel carrying the first data may be interrupted or stopped. Or, the terminal device has already prepared to complete the physical uplink shared channel carrying the first data, and has not sent or sent the physical uplink shared channel carrying the first data, the terminal device may interrupt or stop sending the physical uplink shared channel carrying the first data.

Therefore, in the embodiment of the present application, if DCI carrying a process number of data scheduled by configuration signaling is received within a time window, transmission of the data may be reset, interrupted, or stopped, so that flexible transmission of the data may be achieved.

It should be understood that the above describes 200 and 300, and 400 and 500, respectively, of embodiments of the present application, and it should be understood that the methods of the embodiments of the present application can be used in combination without contradiction.

It should also be understood that in the description of

methods

400 and 500 above, the transmission of the first data is reset, interrupted, or stopped until the DCI is received within the time window. For example, as long as the DCI carries the HARQ process number of the first data, the transmission of the first data may be interrupted or stopped.

In the embodiment of the present application, how to perform the transmission of the data channel will be described below, the following method may be used in combination with the above method 200-500, or may be used independently of the above method 200-500.

Optionally, in this embodiment of the present application, the configuration signaling (which may be DCI or higher layer signaling, etc.) may be used to schedule transmission of first data, where an HARQ process number of the first data is a first HARQ process number, and the DCI may carry the first HARQ process number and is used to schedule second data of the first HARQ process number, where the first data and the second data may be the same or different. For example, the first data and the second data may belong to the same Transport Block (TB) or different TBs, respectively.

Optionally, in this embodiment of the application, when the DCI is used to instruct retransmission of the HARQ process corresponding to the first HARQ process number, feedback information of the first data (downlink data) and feedback information of the second data (downlink data) may be sent (where the feedback information of the first data may be sent on the resource indicated by the DCI together with the feedback information of the second data, or the feedback information of the first data may also be sent on the resource indicated by the configuration signaling), or the feedback information of the second data may be sent without sending the feedback information of the first data.

Optionally, in this embodiment of the present application, the sending time of the DCI may be within a preset time period from the sending time of the higher layer signaling.

Optionally, in this embodiment of the application, the transmission start time of the configuration signaling is earlier than the transmission start time of the DCI signaling, and the transmission end time of the configuration signaling is before the uplink channel transmission time indicated by the DCI signaling.

And when the DCI signaling is used for scheduling the PUSCH, the uplink channel indicated by the DCI signaling is the corresponding PUSCH.

The DCI signaling is used for scheduling a PDSCH or indicating SPS resource release, and an uplink channel indicated by the DCI signaling is a PUCCH or a PUSCH carrying corresponding ACK/NACK feedback information (where at least part of parameters of the PUCCH or the PUSCH are determined according to the DCI).

Optionally, in this embodiment of the application, when the first data and the second data are downlink data, the transmission time of the second data may be earlier than the transmission time of the feedback information of the first data.

Aspects of embodiments of the present application are described below with reference to fig. 10-13, and it should be understood that the following description is only for the convenience of understanding the present application and should not be taken as limiting the present application in any way.

For example, as shown in fig. 10, DCI1 is used to schedule PUSCH1 of HARQ process X, DCI2 carries the process number of HARQ process X, and DCI2 is received within a time window, then the terminal device may stop or terminal PUSCH1 transmission, DCI2 may also be used to schedule PUSCH2, and then PUSCH2 transmission may be performed.

For example, as shown in fig. 11, DCI1 is used to schedule PDSCH1, DCI2 is used to schedule PDSCH2, HARQ process numbers in DCI1 and DCI2 are the same and are both HARQ process X, and after receiving DCI2, the terminal device determines to repeatedly transmit the same process based on the indication of DCI2 (TB may be the same or different), and then receives PDSCH1 and PDSCH 2. The transmission time of the DCI2 is before the ACK/NACK transmission time indicated by the DCI 1. After receiving the DCI2, the terminal device may stop transmitting the ACK/NACK corresponding to the original DCI1 or send the placeholder information, and transmit the ACK/NACK information corresponding to the process only based on the indication of the DCI 2.

Optionally, whether the PDSCH2 is scheduled by old Data or New Data Indicator (NDI) may be determined according to a New Data Indicator (NDI) information field in the DCI2, and whether to process a previous HARQ process may be determined according to a first information field in the DCI2, where processing the previous HARQ process includes whether to stop or interrupt transmission of a Data channel (scheduled by the DCI 1) and/or whether to retransmit or not retransmit the downlink Data scheduled by the DCI 1.

TABLE 1

Alternatively, how to perform subsequent transmission may also be determined according to the second information field in the DCI 2. For example, as shown in table 2, bit 00 represents retransmission and transmission of the same HARQ process, but carries the same original information, bit 01 represents retransmission and transmission of the same HARQ process, but carries different original information, bit 10 represents stop of transmission and/or demodulation of a downlink data channel (indicated by DCI 1) of a previous HARQ process, and bit 11 represents stop of transmission of uplink channel of information related to the previous HARQ process (the uplink channel is used for carrying an uplink data channel corresponding to the previous HARQ process (scheduled by DCI 1) or feedback information of the downlink data channel corresponding to the previous HARQ process).

TABLE 2

Bits	Indicating information
00	Repeat transmission of the same HARQ process (i.e. HARQ process number is the same and TB is the same)
01	The process is transmitted again, but the original information carried is different (i.e. the HARQ process numbers are the same, the TBs are different)
10	Downlink data channel for transmitting and/or demodulating previous HARQ process
11	Uplink channel for stopping transmitting related information of previous HARQ process

When the original information carried is different, the ACK/NACK information corresponding to the PDSCH1 may be transmitted according to the indication of DCI1, and the ACK/NACK information corresponding to the PDSCH2 may be transmitted according to the indication of DCI2, for example, as shown in fig. 12.

For another example, as shown in fig. 13, where HARQ process numbers in DCI1 and DCI2 are the same, after receiving DCI2, the terminal device determines to repeat transmission of the same process based on the indication of DCI2, and then the terminal receives PUSCH1 and PUSCH 2. Wherein the transmission time of the DCI2 is before the PUSCH transmission time scheduled by the DCI1 or before the PUSCH end time or after the PUSCH but the time interval is not more than a predetermined time. A method in which it is determined whether to repeat transmission of the same process based on the indication of DCI2 may refer to a scheme shown in fig. 11.

The wireless communication of the embodiment of the application can be used for high-reliability Low latency Communications (URLLC) services. This service is characterized by an ultra-high reliability (e.g., 99.999%) transmission within an extreme time delay (e.g., 1 ms). In order to meet the requirements of short processing delay and high reliability requirement of URLLC, a more dynamic transmission mechanism should be introduced for URLLC, such as dynamically indicating repeat transmission, and dynamically indicating stop to schedule uplink transmission to avoid collision with other high-priority channels. Therefore, the above method 200-500 of the embodiment of the present application may be particularly suitable for URLLC services, but it should be understood that the method of the embodiment of the present application may also be used for other services, for example, enhanced Mobile bandwidth Band (embb) services.
