Detailed Description
In 5G systems, ultra-reliable and low-latency communication (Ultra-Reliable and Low Latency Communications, URLLC) traffic with extremely high latency, high reliability requirements occurs sporadically and sporadically, thus supporting multiplexed transmission of this traffic on the same resources that transmit other differently demanding traffic helps to reduce transmission latency. When a base station schedules traffic transmissions of different priorities for different terminals, it may happen that two data transmissions of different priorities collide on the same resource, for example, when the base station schedules a mobile broadband enhanced (Enhance Mobile Broadband, eMBB) traffic, and then receives a traffic request of another terminal for scheduling URLLC, and the resource of the URLLC traffic collides with the already scheduled eMBB traffic. In order to ensure the high reliability and low delay requirement of URLLC service with high priority and avoid the interference of eMBB service, some related processing schemes have been proposed at present, such as the base station notifying eMBB service to stop transmitting, or adjusting the transmission power of the service channel, so as to improve the interference elimination performance of the receiving end.
When the terminal transmitting eMBB schedules a plurality of Physical Uplink shared channels (Physical Uplink SHARED CHANNEL, PUSCH) and the plurality of PUSCHs are affected by one URLLC transmission service, the base station needs to inform the terminal to determine which specific PUSCHs stop transmitting.

In the embodiment of the invention, when the terminal has a plurality of channels to be influenced, the terminal can know which channel is particularly influenced, so that unnecessary cancellation operation is avoided, retransmission is reduced, and the system performance is improved.
The flow of the method for uplink channel transmission cancellation is described below in conjunction with embodiments 1 and 2, which are exemplified by eMBB traffic and URLLC traffic.
Example 1:
As shown in fig. 4, it is assumed that three eMBB uplink data traffic channels PUSCH of the terminal ue#1 are scheduled by the network side to be transmitted in slot#n+1, and the three PUSCH numbers are numbered #0, #1, and #2, respectively. The three PUSCHs occupy the symbol numbers of 5,5 and 4 respectively and just occupy one time slot length; meanwhile, the network side schedules URLLC th and 6 th symbol resource positions in slot#n+1 and conflicts with eMBB service resources of the UE#1 on frequency domain resources by transmitting URLLC th service of the terminal UE#2 in slot#n+1.
The base station sends an indication signaling X in slot#n, and uses a group common DCI to carry information, where the DCI is scrambled by a specific radio network temporary identifier (Radio Network Tempory Identity, RNTI), for example, an X-RNTI (X-Radio Network Temporary Identifier ), the DCI contains bit field information of different UEs, the correspondence between each bit field (bit field) and a terminal is configured by a higher layer signaling, and it is assumed that the bit field corresponding to ue#1 in the indication signaling X sent by the base station contains PUSCH number information of 3 bits, in this example, the numbered indication information may be "110" indicating that the PUSCH numbered by #0 and #1 is affected by URLLC services. The indication signaling also contains start position information for indicating the affected start position, such as 4 bits of information, granularity being at symbol level. When the starting position represents the starting position which starts counting after the indication signaling X is detected, the starting position is indicated as 6 symbols; when the starting position represents the starting position of starting counting after the terminal detects the indication signaling X passes through the minimum processing time delay (T) of the terminal, the starting position is indicated as 2 symbols, wherein the minimum processing time delay is 4 symbols. After detecting the signaling, the terminal ue#1 can determine that pusch#0 and pusch#1 are affected by URLLC, perform a cancellation operation starting from the 5 th symbol of pusch#0, and cancel the 5 th symbol of pusch#0 and the transmission of the entire pusch#1.
Example 2:
as shown in fig. 5, it is assumed that three eMBB uplink data traffic channels PUSCH of the terminal ue#1 are scheduled by the network side to be transmitted in slot#n+1, and the three PUSCH numbers are numbered #0, #1, and #2, respectively. The three PUSCHs occupy the symbol numbers of 5,5 and 4 respectively and just occupy one time slot length; meanwhile, the network side schedules URLLC th and 6 th symbol resource positions in slot#n+1 and conflicts with eMBB service resources of the UE#1 on frequency domain resources by transmitting URLLC th service of the terminal UE#2 in slot#n+1.
The base station sends an indication signaling X in slot#n, and DCI bearing information of UE-specific is adopted. Assuming that the bit field in the indication signaling X sent by the base station includes 3 bits of PUSCH number information, the indication information of the number is an indication method of a start and length indication value (START AND LENGTH indicator value, SLIV), and the terminal determines a corresponding cancellation start index and a cancellation time domain length through a SLIV value and a corresponding allocation table. Assuming that the start index represents a cancelled start PUSCH number, the start index S is 0, and the cancelled length spans two PUSCHs, the cancelled length value L is 2, and the SLIV value is 14 assuming SLIV =14 x (L-1) +s. After detecting the signaling X, the terminal ue#1 obtains SLIV a value of 14, and can determine that the S value is 0 and the l value is 2 according to the corresponding allocation table, so as to cancel the transmission of pusch#0 and pusch#1.
The embodiment of the invention also provides a terminal, and the principle of solving the problem of the terminal is similar to that of the method for canceling the uplink channel transmission in the embodiment of the invention, so that the implementation of the terminal can be referred to the implementation of the method, and the repetition is not repeated.
