 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. DCI Format 2_0 DCI format 2_0 is used for notifying the UE of slot format. The SFI is transmitted using regular PDCCH structure and SFI-RNTI, which is common to a group of UEs. To assist the device in the blind decoding, the device is configured with information about the up to two PDCCH candidates on which the SFI can be transmitted. DCI format 2_0 with CRC scrambled with SFI-RNTI carries Slot format indicator 1, Slot format indicator 2, Slot format indicator N. The size of DCI format 2_0 is configurable by higher layers up to 128 bits. DCI Format 2_1 DCI format 2_1 is used to signal the preemption indication to the device. It is transmitted using the regular PDCCH structure, using INT-RNTI which can be com- mon to multiple devices. In other words, DCI format 2_1 is used for notifying the UEs of New Radio Access Physical Layer Aspects (Part 2) 465 the PRB(s) and OFDM symbol(s) that are preempted and have no transmission intended for the UE. DCI format 2_1 with CRC scrambled by INT-RNTI carries Preemption indication 1, Preemption indication 2, Preemption indication N. The size of DCI format 2_1 is configurable by higher layers up to 126 bits where each preemption indi- cation is 14 bits. DCI Format 2_2 The main purpose of DCI format 2_2 is to support power control for semi- persistent scheduling (SPS) since there is no dynamic scheduling assignment or scheduling grant which can include the power control information for PUCCH and PUSCH in this case. The power-control message is addressed to a group of UEs using an RNTI specific for that group and each UE is configured with the power control bits in the message. DCI format 2_2 is further aligned with the size of DCI formats 0_0/1_0 to reduce the blind decoding complex- ity.
