    Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). According to embodiments, a method performed by a distributed unit (DU), the method comprises generating a control plane (C-plane) message for multiple ports, the C-plane message including section information and a section extension; and transmitting the C-plane message to a radio unit (RU) via a specific port of the multiple ports. The section information includes information on a beam identifier (ID). The section extension includes beam group type information for indicating a type of beam grouping, and port information for indicating a total number of one or more extended antenna-carrier (eAxC) ports indicated by the section extension.

    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. In accordance with an aspect of the present disclosure a method by a transmitter using a polar coding is provided. The method includes identifying a length of interleaved transmission bits; identifying a length of a buffer corresponding to the interleaved transmission bits; determining a procedure from a first procedure and a second procedure based on at least one of the length of interleaved transmission bits and the length of buffer, if the length of the interleaved transmission bits is less than the length of the buffer; and storing the interleaved transmission bits at the buffer based on the determined procedure.

    Abstract: A method for transmitting signals by a first device of a base station transmitting and receiving signals of a wireless communication system is provided. The method includes receiving a plurality of uplink signals, identifying uplink transmission shaping information to be applied to the plurality of uplink signals, and transmitting the plurality of uplink signals to a second device by applying the uplink transmission shaping. The uplink transmission shaping information is information indicating for how many time intervals the first device is to transmit the plurality of uplink signals to the second device using a fronthaul. If the plurality of uplink signals are received by the first device for a first time, the plurality of uplink signals to which the uplink transmission shaping is applied are transmitted by the first device to the second device for the first time and a time determined based on the uplink transmission shaping information.

    Abstract: Disclosed are: a communication method for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system; and a system thereof. The present disclosure can be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail, security and safety related services, and the like) on the basis of a 5G communication technology and an IoT-related technology. A method by which a transmitter in a communication system transmits signals, according to one embodiment of the present specification, comprises the steps of: determining depth information for generating a mother code size and a parity bit; applying a polar code sequence corresponding to an information bit; generating, on the basis of the mother code size and the depth information, a codeword including a parity bit associated with at least two bits among a plurality of bits to which the polar code sequence is applied; and transmitting the generated codeword.
