5G(NR）网络中小区下行资源调度通过 DCI(Downlink Control Information) 进行指
示；在 3GPP TS38.212 - 7.3 中 定义了八种格式（DCI formats），其具体内容如下：
DCI Format
Usage
Format 0_0
Scheduling of PUSCH in one cell
Format 0_1
Scheduling of PUSCH in one cell
Format 1_0
Scheduling of PDSCH in one cell
DCI format 1_0 with CRC scrambled by C-RNTI
DCI format 1_0 with CRC scrambled by RA-RNTI
DCI format 1_0 with CRC scrambled by TC-RNTI
DCI format 1_0 with CRC scrambled by SI-RNTI
DCI format 1_0 with CRC scrambled by P-RNTI
Format 1_1
Scheduling of PDSCH in one cell
Format 2_0
Notifying a group of UEs of the slot format
Format 2_1
Notifying a group of UEs of the PRB(s) and OFDM symbol(s) where UE may assume no
transmission is intended for the UE
Format 2_2
Transmission of TPC commands for PUCCH and PUSCH
Format 2_3
Transmission of a group of TPC commands for SRS transmissions by one or more UEs
