Question: What is the primary purpose of transmitting DCI (Downlink Control Information) format 2_0 in a 5G New Radio (NR) network, and what is the maximum configurable size of this format as per higher layer configurations?
Option 1: To schedule uplink transmissions with a fixed size of 64 bits.
Option 2: To notify slot format, COT duration, available RB set, and search space set group switching with a maximum configurable size of 256 bits.
Option 3: To indicate handover commands between cells with a variable size up to 512 bits.
Option 4: To inform the User Equipment (UE) about slot format, COT duration, available RB set, and search space set group switching with a maximum configurable size of 128 bits.
Explanation: DCI format 2_0 is specifically used for notifying several key network configurations to the UE, including slot format, COT (Control Resource Set) duration, available Resource Block (RB) sets, and search space set group switching. The size of this DCI format can be configured by higher layers up to a maximum of 128 bits, ensuring flexibility in the amount of information conveyed based on network needs, as per the specifications outlined for physical layer procedures in 5G NR networks.
