Abstract: Methods and apparatuses are provided in which a base station transmits a synchronization signal (SS) physical broadcast channel (PBCH) block (SSB) associated with a master information block (MIB) including first configuration information for a first control resource set (CORESET) associated with a common search space (CSS). System information is transmitted. The terminal obtains MIB based on the SSB, monitors first control information for scheduling the system information on the CSS based on a first aggregation level, and receives the system information based on the first control information. A radio resource control (RRC) connection is established with the terminal based on the system information. An RRC message is transmitted to the terminal including second configuration information for a second CORESET associated with a UE specific search space (USS), based on the RRC connection. The terminal monitors second control information for the UE on the USS based on a second aggregation level.

Abstract: The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting higher data transmission rates than 4th generation (4G) communication systems such as Long Term Evolution (LTE). According to an embodiment according to the present disclosure, provided is a method performed in a communication system by a terminal. The method performed by the terminal operation may include receiving configuration information about semi-static scheduling; receiving downlink control information (DCI) through a physical downlink control channel (PDCCH); checking whether the DCI activates the semi-static scheduling; checking whether the semi-static scheduling is configured in a bandwidth part (BWP), indicated by a BWP indicator included in the DCI, when the semi-static scheduling is activated; and discarding the DCI when the semi-static scheduling is not configured in the BWP.
