Abstract: Methods and apparatuses are provided in a wireless communication system. A terminal receives a feedback configuration including a configuration for a wideband or a subband from a base station. The terminal receives, from the base station, quasi co-location (QCL) information for a physical downlink control channel (PDCCH) via medium access control-control element (MAC-CE) signaling. The terminal receives, from the base station, the PDCCH based on the QCL information for the PDCCH. The terminal reports channel state information (CSI) for a CSI-RS resource configuration based on the PDCCH and the feedback configuration.

Abstract: A method performed by a terminal in a communication system is provided. Information on a demodulation reference signal (DMRS) configuration type corresponding to a mapping pattern of a plurality of DMRS ports is received from a base station. Control information indicating at least one DMRS port among the plurality of DMRS ports is received from the base station. The at least one DMRS port associated with downlink data is identified based on the control information. Downlink data based on the identified DMRS port is received from the base station. The plurality of DMRS ports belong to two or three DMRS groups based on a DMRS configuration type. Resources corresponding to different DMRS groups are multiplexed based on an orthogonal code.

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. A method by which a terminal receives a signal in a mobile communication system, according to one embodiment of the present specification, comprises the steps of: receiving channel state information-reference signal (CSI-RS) mode information; and receiving a signal on the basis of the CSI-RS mode information. Unlike a conventional method of allowing a base station to periodically set the CSI-RS in a terminal at a predetermined position such that the terminal receives the CSI-RS and generates and reports channel state information, the present invention proposes a method by which a base station allocates, to a terminal, a reference signal transmission for enabling aperiodic generation of the channel state information for a system having various numbers of transmission antenna ports such as one, two, four, eight, twelve, sixteen or thirty-two transmission antenna ports, and receives the channel state information report. In addition, a method for transferring ZP CSI-RS and quasi co-location (QCL) information for supporting rate matching thereby is also proposed.
