Second, therefore the present embodiment is by that quickly can export frequency domain dispatching in advance for frequency domain dispatching as a result, its advantage is that control on the one hand can be improved
The dispatching in face processed, still further aspect can be to other parts and the physical layer descending remaining processing times more out of L2.Work as control
After P1 time point exports frequency domain dispatching result, the remaining P1-P3 period can be used for handling domain scheduling when including in face processed
Other control plane functions including function, in this way will not in the presence of domain scheduling and frequency domain dispatching the problem of being overlapped mutually influence.
Preferably, if frequency domain dispatching has been carried out to some user in some schedulable TTI, after frequency domain dispatching is completed, if the use
Family has issued scheduling request, then can update user according to the result and the scheduling request of frequency domain dispatching in current schedulable TTI
