    Abstract: Provided are a method and device for monitoring a physical downlink control channel (POOCH) in a wireless communication system. The method, performed by a terminal supporting carrier aggregation, of monitoring the physical downlink control channel (PDCCH) includes: receiving configuration information about a low power mode indicator that controls monitoring of a PDCCH, in at least one of a plurality of cells; based on the configuration information, determining whether the low power mode indicator is detected, in at least one cell for which the configuration information is received; and based on a result of the determining and information about a cell associated with the low power mode indicator, controlling the monitoring of the PDCCH, in a cell associated with the low power mode indicator from among the plurality of cells.

    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present 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 present invention provides a method and an apparatus which can achieve accurate time and frequency synchronization while reducing system load, in line with the design requirements for a 5G communication system. Particularly, the present invention provides a method for acquiring time and frequency synchronization by a terminal in a communication system, the method comprising the steps of: receiving a first synchronization signal from a base station; receiving a second synchronization signal from the base station; and receiving a channel state information-reference signal (CSI-RS) from the base station, and acquiring downlink time and frequency synchronization with the base station on the basis of the CSI-RS.

    Abstract: A communication method and system that combine the internet of things (IoT) technology with fifth generation (5G) communication systems supporting a higher data rate after fourth generation (4G) systems are provided. The present disclosure may be applied to intelligent services, such as smart homes, smart buildings, smart cities, smart or connected cars, healthcare, digital education, retail businesses, and security and safety related services on the basis of 5G communication technologies and IoT related technologies. A method of a terminal in a wireless communication system to improve DMRS channel estimation performance is provided. The method includes receiving first information configuring a physical resource block (PRB) bundling size indication based on second information, receiving the second information indicating the number of at least one PRB, if the PRB bundling size indication is configured, and estimating the channel state based on an assumption that the same precoding is applied to the at least one PRB based on the second information.
