figured for a UE by cell-specific and/or UE-specific higher layer signaling in a semi-static downlink/uplink assignment manner, or by dynamically signaling via DCI in group-common PDCCH (GC- PDCCH). When the dynamic signaling is configured, a UE should monitor GC-PDCCH which carries dynamic slot format indication (SFI). When a device enters the connected state, it has already obtained the information from PBCH about the CORESET where it can find the control channel used to schedule the RMSI. The CORESET configuration obtained from PBCH also defines and activates the initial bandwidth part in the downlink. The initial active uplink bandwidth part is obtained from the SI scheduled using the downlink PDCCH. 440 Chapter 4 v=0 236 v=2 236 PBCH DM-RS Figure 4.13 PBCH DM-RS location shift by physical cell ID 30]. In NR, the device typically attempts to blindly decode candidate PDCCHs transmitted from the network using one or more search spaces. However, there are some differences com- pared to LTE based on the different design targets for NR as well as the experience learned from LTE deployments. Unlike LTE PDCCH, the PDCCH in NR does not span the entire carrier bandwidth. This is due to the fact that NR devices may not be able to operate over New Radio Access Physical Layer Aspects (Part 2) 441 the full carrier bandwidth of the gNB. The PDCCH in NR is designed to support UE- specific beamforming, which is the result of beam-centric physical-layer design of NR and a requirement when operating in mmWave bands with challenging link budgets. 4.1.3.2.1 Structure and Physical Layer Processing of PDCCH A UE-specific PDCCH is used to schedule downlink and uplink transmissions on PDSCH and PUSCH, respectively. The DCI on PDCCH contains downlink assignments including modulation and coding format, resource allocation, and HARQ information related to DL-SCH; uplink scheduling grants including modulation and coding format, resource allo- cation, and HARQ information related to UL-SCH. The control channels are formed by aggregation
