Channel Setup DCI

Downlink Control Information (DCI) is used to transport downlink control information for one or more cells with one radio network transportation identifier (RNTI) to the PDCCH physical channel.

This topic describes the following DCI properties:

Channel Editor

Channel Editor

Many of the channel types described in this topic provide a convenient channel editor, in table format, for convenient viewing and configuring of multiple channels. The editing functions for adding, removing, and copying rows appear directly above the editor. As you make edits, the Channel Allocation graph updates and, if a channel conflict occurs, an error message appears, describing the conflict.

	Add Row	Adds a new channel row to the bottom of the table with default settings. The name of the new channel increments numerically.
	Remove Row	Removes the currently selected channel row.
	Copy Row	Copies the currently selected channel row to the bottom of the table and appends "_Copy" to its name.
	Add from Menu	Opens a drop-down menu of unique channel editing choices you can apply to the table. Not available for all channels.

Resource Allocation

Time domain: Use Allocated Slots to set slot allocation, and the symbol allocation is determined by the CORESET selection.
Frequency domain: Select BWP first, and then CORESET index in the BWP. After selecting CORESET index, use CCE offset and CCE number to set the frequency location of DCI.

Allocated Slots

Controls the allocated slot index for DCI transmission.

Sets the allocated slot index for the channel. Allocated Slots are entered as an array of slot indexes allocated for the PUCCH. There are three ways to configure:

To configure by individual index, use ',' as the delimiter, e.g. 0,1,2,3.
To configure by a range of index, use ':' to indicate the start index and the last index, e.g. 3:10 means 3,4,5,6,7,8,9,10.
To configure by a certain step, use two ':' to indicate the start index, the step and the last index, e.g. 0:4:12 means 0, 4, 8, 12.

These three configuration methods can be used in combination, by using ',' as the delimiter, e.g. 0,1,4:7,8:2:19 means index 0,1,4,5,6,7,8,10,12,14,16,18.

If the slot allocation is different for different frame, use '{ }' and '|' to specify the frame index, for example, {0|0,1,2},{1|3,4,5} means slot 0,1,2 for frame 0, and slot 3,4,5 for frame 1. Ensure the Number of Radio Frames under Waveform Setup node is large enough.

SCPI Example	RAD:NR5G:WAV:CCAR0:DLIN:DCI0:SLOT "0:10" RAD:NR5G:WAV:CCAR0:DLIN:DCI0:SLOT?
Couplings	The range of slot index is from 0 to the number of slots in the frame of the current numerology - 1. The to number of slots in the frame is coupled with the numerology used by this channel, which is defined in the selected BWP and refer to the Frame Structure table for the details about the relationship between number of slots in the frame and numerology.
