Embodiment 1
[0096] In this embodiment, the original bit indicating DCI5 is 10bit. The meaning of each field is shown in Table 1. It includes the uplink and downlink DCI indication, the number of downlink services and the number of uplink services, as well as the aggregation degree of the downlink DCI. Indication, an indication of the aggregation degree of the uplink DCI. For a certain user, there is only one indication of the aggregation degree of the downlink / uplink DCI. Therefore, when scheduling, the aggregation degree of the DCI corresponding to all services is the same, and the flexibility of scheduling is slightly worse. However, considering that the DCI detection requirements are higher High, and each DCI is discretely distributed in time-frequency resources, so it is reasonable to use the same aggregation degree for all DCIs of the same user. Table 1 also lists: there are 4 downlink services for the same user, and there is no uplink service indicating the value of DCI.

Embodiment 2
[0103] In this embodiment, the original bit indicating DCI5 is 22 bits, and the meaning of each field is shown in Table 1. It includes the uplink and downlink DCI indication, the number of downlink services, the number of uplink services, and the number of each downlink DCI. The aggregation degree indicator, the aggregation degree indicator of each uplink DCI. For a user, the downlink / uplink DCI aggregation degree indication can be different, and the scheduling is more flexible, but the original number of bits of the DCI indication is large, and it takes up more time-frequency resources when the bit rate is low. . Table 2 also lists: when the same user has 2 uplink services and 4 downlink services, the value of DCI is indicated.
[0104] The eNB combines the indication DCI according to the scheduling situation of a certain UE, and sends the indication DCI. If the eNB does not schedule a certain UE, the corresponding indication DCI will not be sent. The sending process of indic...
Embodiment 3
[0111] In this embodiment, the original bit indicating DCI5 is 16 bits. The meaning of each field is shown in Table 3. It includes the uplink and downlink DCI indication, the number of downlink services, and the number of uplink services. There are also two sets of downlink DCI indicators. Aggregation degree indicator, the aggregation degree indicator of two sets of uplink DCI. For a certain user, the downlink / uplink DCI aggregation indicators can be different, but there are only two combinations, but the design indicates that the original number of DCI bits is less than in the embodiment. Under the condition that the guaranteed bit rate is low, the occupancy is higher. Fewer time-frequency resources. Table 3 also lists: the same user has 4 uplink services, and there is no downlink service indicating the value of DCI.
[0112] The eNB combines the indication DCI according to the scheduling situation of a certain UE, and sends the indication DCI. If the eNB does not schedule a c...
