Other business datums of terminal device Slot N+1 for other terminal devices or this terminal device, at this point, obeying DCI's 2
Scheduling, Slot N+1 are no longer participate in data in this time multi-slot scheduling process and send.Although Slot N+1 exists
It in the continuous time slots of aggregation-factor-UL=4, and is also to be used for upstream data, but due to the time slot
Resource is seized by the signaling of high priority, therefore Slot N+1 carries out data transmission not as continuous slot.In the case, only
There are Slot N, Slot N+2, Slot N+3 to carry out continuous data transmission.
In the situation that Fig. 3 is indicated, Slot N+1 is only an example of the time slot that the signaling of high priority is seized.Together
Reason, if the running time-frequency resource of Slot N+3 is seized by the signaling of high priority, abandons Slot N+3.
