Abstract: A user equipment (UE) for receiving control information in a wireless communication system includes a transceiver configured to receive a synchronization signal/physical broadcasting channel (SS/PBCH) block of an index i from a BS, wherein SS/PBCH block comprises a PBCH carrying master information block (MIB). The UE includes a processor configured to for the SS/PBCH block of the index i, determine a slot index n0 as a sum of an offset value and └i*M┘. The offset value is determined based on a first value O determined according to the index indicated in the MIB, wherein the index configures PDCCH monitoring occasions, and a second value μ indicated in the MIB, wherein the second value μ represents a subcarrier spacing configuration, wherein M is a positive number determined according to the index indicated in the MIB, and cause the transceiver to decode a PDCCH in the slot index n0.

Abstract: The present invention defines a method for controlling uplink transmission power of a terminal in a communication system which is operated by combining heterogeneous systems. Specifically, the present invention defines a method for selectively applying a power control command in order to control uplink power of a terminal in a communication system which is operated by combining an LTE/LTE-A system with a system which applies a new radio access technology, and a method for differently operating power control units depending on whether beam sweeping is applied or not. Such methods efficiently control transmission power of a terminal, and lower the generation of uplink interference signals, thereby improving system efficiency.
