H35-481_V2-0 practice question 8 of 15

Which of the following Information Is not carried In the DCI of NR?

Full set: 60 questions
Answer options
A: PUSCH scheduling
B: PUSCH power control
C: PMI report Correct answer
D: PDSCH scheduling
Correct Answer:
C. PMI report
Explanation

Downlink Control Information (DCI) is transmitted from the gNB to the UE on the PDCCH to schedule resources and provide control commands. DCI formats carry information such as PDSCH scheduling assignments for downlink data, PUSCH scheduling grants for uplink data, and Transmit Power Control (TPC) commands for the PUSCH. A Precoding Matrix Indicator (PMI) report is part of the Channel State Information (CSI) that the UE reports to the gNB in the uplink (on PUCCH or PUSCH). While a DCI can trigger an aperiodic CSI report, the DCI itself does not contain the PMI report.

Why Incorrect

A. PUSCH scheduling information (an uplink grant) is a primary component of DCI formats like 00 and 01.
B. PUSCH power control commands (TPC commands) are included in the DCI formats that grant uplink resources.
D. PDSCH scheduling information (a downlink assignment) is a primary component of DCI formats like 10 and 11.
