The transmission resource is resource 1. The HARQ process number in DCI 2 is the same as any one of the three PDSCHs. Then, the resource 1 stops transmitting the uplink channel carrying the ACK/NACK . At this time, DCI 2 can schedule a valid PDSCH 4 transmission and indicate a new uplink channel resource, that is, resource 2, transmits ACK/NACK, and the ACK/NACK transmitted in the new uplink channel may include at least part of the three PDSCH The corresponding ACK/NACK information and may include ACK/NACK information corresponding to PDSCH4.

For example, as shown in FIG. 6, three DCIs schedule three PDSCHs respectively, and the HARQ processes of the three PDSCHs are HARQ process X, HARQ process Y, and HARQ process Z, respectively, and the ACK/NACK information of the three PDSCHs passes through one uplink For channel multiplexing transmission, the transmission resource is resource 1, and the HARQ process number in DCI 2 is the same as any one of the three PDSCHs. Then, resource 1 stops transmitting the uplink channel carrying the ACK/NACK. At this time, sending DCI 2 does not expect a new PDSCH, but is only used to instruct the uplink channel to stop transmission. At this time, a new uplink channel resource, that is, resource 2, is used to transmit ACK/NACK information corresponding to the three PDSCHs.

Wherein, the DCI does not schedule the PDSCH by setting the specific information field in the DCI to the agreed value.

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

The solution shown in FIG. 7 is similar to the solution shown in FIG. 6, the difference is that the solution shown in FIG. 6 requires that the upstream channel corresponding to DCI 1 be stopped. The solution shown in FIG. 6 does not require that the previous transmission must be stopped. Whether to stop depends on the terminal The algorithm is implemented specifically, but the terminal must transmit the previous ACK/NACK information on the newly indicated resource. As shown in FIG. 7, if the transmission time of DCI 2 is very close to or even coincides with the ACK/NACK transmission time indicated previously, the terminal cannot cancel the previous transmission action, but must send again according to the instruction of DCI 2.

The solutions of the embodiments of the present application will be described below with reference to FIGS. 10-13. It should be understood that the following description is only for the convenience of understanding the present application, and should not be particularly limited to this application.

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

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

Optionally, it can be determined whether the PDSCH 2 schedules the old data or the new belongs according to the New Data Indicator (NDI) information field in DCI2, and whether to process the previous time is determined according to the first information field in DCI2 HARQ process, wherein the processing of the previous HARQ process includes feedback information on whether to stop or interrupt the transmission of the data channel (scheduled by DCI1) and/or whether to retransmit or not to transmit the downlink data scheduled by DCI1.

Table 1

Alternatively, it can also determine how to perform subsequent transmission according to the second information field in the DCI2. For example, as shown in Table 2, bit 00 represents retransmission and transmission of the same HARQ process, but the original information carried is the same, bit 01 represents transmission of the same HARQ process again, but the original information carried is different, and bit 10 represents the stop of transmission and/or solution. Adjust the downlink data channel of the previous HARQ process (indicated by DCI1), bit 11 represents the uplink channel that stops transmitting information about the previous HARQ process (the uplink channel is used to carry the uplink data channel corresponding to the previous HARQ process (scheduled by DCI1) , Or the feedback information of the downlink data channel corresponding to the previous HARQ process).

Table 2

比特Bit	指示信息Instructions
0000	重复传输同一HARQ进程(即HARQ进程号相同，TB相同)Repeat transmission of the same HARQ process (ie HARQ process ID is the same, TB is the same)
0101	再次传输该进程，但承载的原信息不同(即HARQ进程号相同，TB不同)The process is transmitted again, but the original information carried is different (that is, the HARQ process number is the same, the TB is different)
1010	传输和/或解调前次HARQ进程的下行数据信道Transmission and/or demodulation of the downstream data channel of the previous HARQ process
1111	停止传输前次HARQ进程相关信息的上行信道Stop the uplink channel that transmits information about the previous HARQ process

Among them, when the original information carried is different, the ACK/NACK information corresponding to PDSCH 1 can be transmitted according to the instruction of DCI 1, and the ACK/NACK information corresponding to PDSCH 2 can be transmitted according to the instruction of DCI 2, for example, as shown in FIG. 12.

For another example, as shown in FIG. 13, in which the HARQ process numbers in DCI 1 and DCI 2 are the same, after the terminal device receives DCI 2, and determines to repeatedly transmit the same process based on the indication of DCI 2, the terminal receives PUSCH 1 and PUSCH 2 . The transmission time of 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 greater than a predetermined time. For a method for determining whether to repeatedly transmit the same process based on the indication of the DCI 2, refer to the solution shown in FIG. 11.

The wireless communication according to the embodiment of the present application may be used for high-reliability and low-latency communication (Ultra-Reliable Low Latency Communications, URLLC) services. The feature of this service is to achieve ultra-high reliability (eg, 99.999%) transmission within extreme delays (eg, 1 ms). In order to meet the requirements of URLLC processing delay and high reliability requirements, URLLC should introduce a more dynamic transmission mechanism, such as dynamic indication of repeated transmission, dynamic indication to stop to schedule uplink transmission to avoid collision with other high priority channels. Therefore, the above methods 200-500 of the embodiments of the present application may be particularly applicable to URLLC services, but it should be understood that the methods of the embodiments of the present application may also be used for other services, for example, enhanced mobile bandwidth (enhanced Mobile Broadband, eMMB) business.
