    Abstract: A method and a device for transmitting or receiving uplink control information in a wireless communication system are provided. The method includes receiving, from a base station, an indicator indicating whether hybrid automatic repeat request acknowledgement (HARQ-ACK) information and configured grant-uplink control information (CG-UCI) are to be joint-encoded, identifying that a transmission of the HARQ-ACK information overlaps with a configured grant-physical uplink shared channel (CG-PUSCH) transmission, when the indicator indicates the HARQ-ACK information and the CG-UCI are to be joint-encoded, performing a joint-encoding of the HARQ-ACK information and the CG-UCI, determining a number of coded modulation symbols for the HARQ-ACK information and the CG-UCI based on a beta offset value for the HARQ-ACK information, and transmitting, to the base station, uplink data on the CG-PUSCH with the HARQ-ACK information and the CG-UCI based on the determined number of coded modulation symbols.

    Abstract: The disclosure relates to a communication technique for converging a 5G communication system for supporting a higher data transfer rate beyond a 4G system with an IoT technology, and a system therefor. The disclosure may be applied to intelligent services (for example, smart home, smart buildings, smart cities, smart cars or connected cars, health care, digital educations, retail business, security and safety-related services, etc.) based on a 5G communication technology and an IoT-related technology. The disclosure provides an apparatus and a method for efficiently decoding a low-density parity-check (LDPC) code in a communication or broadcasting system. Further, the disclosure provides an LDPC decoding device and method for improving decoding performance without increasing the decoding complexity by applying suitable decoding scheduling according to the structural or algebraic characteristics of the LDPC code in a process of decoding the LDPC code using layered scheduling or a scheme similar thereto. Further, a method of a low density parity check (LDPC) decoding performed by a receiving device in a wireless communication system is provided, the method comprising: receiving, from a transmitting device, a signal corresponding to input bits; performing demodulation based on the signal to determine values corresponding to the input bits; identifying a number of the input bits based on the signal; identifying a base matrix and a lifting size based on the number of the input bits; identifying a parity check matrix based on the base matrix; identifying an index corresponding to the values; determining a number of layers based on the index and the lifting size; determining an order for LDPC decoding based on the number of layers and a predetermined sequence; and performing LDPC decoding to determine the input bits based on the values, the parity check matrix and the order.

    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 of a terminal in a wireless communication system is provided. The method includes identifying demodulation reference signal (DMRS) type information and DMRS symbol length information, identifying port number information for receiving a DMRS and receiving the DMRS based on the DMRS type information, the DMRS symbol length information and port number information, wherein the port number information indicates a port number for the terminal in DMRS information including parameters for code division multiplexing (CDM) group information, offset information, frequency-domain orthogonal cover code (OCC) information, and time-domain OCC information corresponding respectively to multiple port numbers, and wherein the DMRS information is defined per DMRS type.
