    Abstract: A method of transmitting and receiving a signal, by a base station (BS), in a wireless communication system is provided. The method includes determining whether each of at least one terminal connected to the BS supports nonlinear precoding (NLP) or a modulo operation, determining a plurality of signals that are overlapping-transmitted in a time-frequency resource region from among a control signal, a reference signal (RS), and a data signal transmitted from the BS, based on whether the at least one terminal supports the NLP or the modulo operation, and transmitting, to each of the at least one terminal, information about whether the NLP or the modulo operation is performed in a resource where the plurality of signals are transmitted.

    Abstract: A method of an evolved Node B (eNB) in a wireless environment is provided. The method includes receiving, from a user equipment (UE), a plurality of channel state information (CSI) feedback respectively corresponding to a plurality of CSI processes that are respectively allocated a plurality of precoding matrix indexes (PMIs), determining a modulation and coding scheme (MCS) value based on the plurality of received CSI feedback, and transmitting, to the UE, data modulated based on the determined MCS value by cyclically using the plurality of PMIs, wherein the plurality of CSI feedback may each include information on a channel quality indication (CQI) as to a PMI allocated to a CSI process corresponding to each of the plurality of CSI feedback.

    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Ggeneration (5G) communication system for supporting higher data rates beyond a 4th-Ggeneration (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 homes, smart buildings, smart cities, smart cars, connected cars, health care, digital education, smart retail, security, and safety services. A method of transmitting uplink control information in a wireless communication system is provided. The method includes receiving channel state information (CSI) feedback configuration information from a base station, generating (CSI) including at least one of a CSI reference signal resource indicator (CRI), a rank indicator (RI), a precoding matrix indicator (PMI), or a channel quality indicator (CQI) based on the CSI feedback configuration information, identifying an information sequence including the CSI, encoding the information sequence using a polar code, and transmitting the encoded information sequence to a base station. The CRI and the RI are placed before padding bits in the information sequence and the PMI and the CQI are placed after the padding bits in the information sequence.

    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.
