5G NR DCI Formats | Fields in 5G NR DCI formats
This page mentions 5G NR DCI Formats tables. It describes functions and fields used in 5G NR DCI formats viz. format 0_0, format 0_1, format 1_0, format 1_1, format 2_0, format 2_1, format 2_2 and format 2_3.
Introduction:
DCI is the short form of Downlink Control Information.
It is used to transport downlink control information for one or more cells with one RNTI.
Following coding steps can be identified which include Information Element multiplexing,
CRC attachment, channel coding and rate matching.
Following table mentions functions of DCI format types defined in 3GPP TS 38.212 V15 published in June 2018. Its function is same as LTE DCI. It is used to schedule PUSCH and PDSCH.
| 5G NR DCI Format type | Usage description |
|---|---|
| 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 |
| 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. |
