No matter adopt above-mentioned which kind of mode, if the part subframe in the network equipment 10 scheduling N continuous descending sub frame, then network equipment 10 also needs the schedule information of the descending sub frame correspondence that will not be scheduled to place the 2nd DCI information.

In order to allow terminal 20 discern which descending sub frame are the descending sub frames that are not scheduled, and network equipment 10 can be provided with some specific informations in the schedule information of the descending sub frame correspondence of not dispatching.Enumerate dual mode below.

1, network equipment 10 can be arranged to the HARQ process number of the descending sub frame m that do not dispatch identical with the HARQ process number of the descending sub frame m ' of the immediate scheduling in position; Wherein, m is a positive integer, and m ' is a positive integer, and n≤m '＜m;

Accordingly, terminal 20 is at N that the 2nd DCI information can be dispatched continuously in the descending sub frame, determines that the HARQ number of carrying out of the HARQ number of carrying out of descending sub frame m in the 2nd DCI information and descending sub frame m ' is identical, and determining does not have downlink data among the descending sub frame m.

Such as subframe 1 is the subframe that is scheduled, and subframe 2 and 3 is the subframes that are not scheduled, and then subframe 2 is identical with the HARQ process number with subframe 1 that 3 HARQ process number is provided with.

Terminal 20 just knows that subframe 2 is not the subframe that is scheduled after the HARQ process number of determining subframe 1 and subframe 2 is identical; In like manner after the HARQ process number of determining subframe 1 and subframe 3 is identical, just know that subframe 3 is not the subframe that is scheduled.
