Method and apparatus for configuring control channel for nr in wireless communication system

A user equipment (UE) in a wireless communication system, the UE comprising:

• a memory;
• a transceiver;
• and
• a processor, operably coupled to the memory and the transceiver,
• wherein the transceiver is configured to receive a configuration of a control resource set for a remaining minimum system information (RMSI) via a physical broadcast channel (PBCH) from a network,
• wherein the processor is configured to determine the control resource set for the RMSI based the configuration,
• wherein the transceiver is configured to monitor a control channel to receive downlink control information (DCI) in the control resource set for the RMSI based on a beam which is mapped to a synchronization signal (SS) block, and
• wherein the transceiver is configured to receive the RMSI based on the DCI from the network.
