 used to request transmission of a sounding RS. New Radio Access Physical Layer Aspects (Part 2 461 CSI request (0, 1, 2, 3, 4, 5, or 6 bits): This field is used to request transmission of a CSI report. Code block group (CBG) transmission information (0, 2, 4, 6, or 8 bits): This field indi- cates the code block groups for retransmission. PT-RS-DM-RS association (0 or 2 bits): This field is used to indicate the association between the DM-RS and PT-RS ports. beta_offset Indicator (0 or 2 bits): This information is used to control the amount of resources used by UCI on PUSCH in case dynamic beta offset signaling is configured for DCI format 0_1. DM-RS sequence initialization (0 or 1 bit): This information is used to select between two preconfigured initialization values for the DM-RS sequence. It would be zero bit, if the transform precoder is enabled and 1 bit, otherwise. Uplink/SUL indicator (0 or 1 bit): It would be zero bit for UEs that are not configured with SUL in the cell or UEs configured with SUL in the cell but only physical uplink control channel (PUCCH) carrier in the cell is configured for PUSCH transmission; oth- erwise, 0 bit for UEs configured with SUL in the cell. DCI Format 1_0 Identifier for DCI formats (1 bit): A bit to indicate whether the DCI is a downlink assignment or an uplink grant. The value of this field is always set to 1, indicating a downlink DCI format. Frequency-domain resource assignment: This field indicates the resource blocks on one component carrier on which the UE receives PDSCH. The size of this field depends on the size of the bandwidth part and on the resource allocation type, that is, Type 0 only, Type 1 only, or dynamic switching between the two types. The number of bits is where the interpretation of NDL,BWP depends on the search space where DCI format 1_0 is monitored. The parameter NDL,BWP indicates the size of the active downlink bandwidth part, if DCI format 1_0 is monitored in the UE- specific search space and if the total number of different DCI sizes configured t
