    Abstract: The present disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. In addition, the present disclosure relates to a method carried out by a base station of a wireless communication system, and a device for carrying out same, the method comprising the steps of: determining whether a frequency band operated by a base station uses a bandwidth that is narrower than a preset bandwidth; if a bandwidth that is narrower than the preset bandwidth is used, determining a subcarrier spacing (SCS) that is narrower than a preset SCS; generating a synchronization signal block (SSB) using the determined SCS; and transmitting the SSB, wherein the determined SCS is smaller than 15 kHz.

    Abstract: The present disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate than a 4G communication system such as LTE. According to various embodiments of the present disclosure, a method performed by a transmission apparatus in a wireless communication system may be provided. The method may comprise the steps of: transmitting, via a physical downlink control channel (PDCCH), first control information for scheduling a group common-physical downlink shared channel (GC-PDSCH) via which multicast data is transmitted, including information related to hybrid automatic repeat request (HARQ) feedback for the multicast data; and transmitting, via the PDCCH, second control information for scheduling a physical downlink shared channel (PDSCH) via which unicast data is transmitted, including information related to HARQ feedback for the unicast data.

    Abstract: The disclosure relates to a communication method and system for converging a 5G communication system for supporting higher data rates beyond a 4G system with a technology for IoT. The disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The disclosure provides a method performed by a terminal in a wireless communication system. The method includes receiving, from a base station, information configuring a list of aperiodic trigger states for CSI; receiving, from the base station, DCI including a CSI request field, wherein each codepoint of the CSI request field is associated with one trigger state of the list and a CSI-RS is triggered based on a trigger state indicated by the CSI request field; identifying whether a BWP in which the CSI-RS is received is non-active; and in case that the BWP in which the CSI-RS is received is non-active, skipping a measurement of the CSI-RS.
