    Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate beyond the 4G communication system such as LTE. A decoding method using a polar code according to an embodiment of the present disclosure comprises the steps of: determining a first function for decoding input bits and a second function, which is independent from a log likelihood ratio (LLR) value of a previous input bit by the first function; and decoding the input bits in parallel using the first function and the second function. Also, the method comprises the steps of: determining an internal frozen bit using at least one input frozen bit which has a predetermined value of a predetermined position from among the input bits; and determining LLR values for layer bits sequentially from the higher layers of N layers.

    Abstract: A method for performing scheduling by a first base station over a wireless communication network, and an apparatus therfor are provided. The method includes receiving first channel status information (CSI) measured by at least one user equipment (UE) positioned in coverage of the first base station and second CSI, determining a first transmission rate for any one of the at least one UE positioned in the coverage of the first base station and a second transmission rate for any one of the at least one UE positioned in the coverage of the second base station, determining a third transmission rate for a first UE among the at least one UE positioned in the coverage of the first base station and a fourth transmission rate for a second UE among the at least one UE positioned in the coverage of the second base station, and performing scheduling.

    Abstract: A 5th-generation (5G) or pre-5G communication system which is to support a higher data transfer rate beyond a 4G communication system such as a long term evolution (LTE) is provided. The method for transmitting a downlink signal by a base station in a wireless communication system supporting non-orthogonal multiple access (NOMA) includes the steps of selecting a pair of terminals including one short-distance terminal and at least one long-distance terminal which will share an identical downlink transmission resource, generating a superimposed signal in which a signal for the short-distance terminal and a signal for the long-distance terminal are superimposed on one another, generating information necessary for cancelling the signal of the long-distance terminal from the superimposed signal, transmitting the generated information necessary for cancelling the signal of the long-distance terminal to the short-distance terminal, and transmitting the generated superimposed signal to the pair of terminals.

    Abstract: Disclosed is a method and apparatus for transmitting information in a communication system. The present invention relates to a millimeter wave beamforming-based 5G or pre-5G wireless communication system for supporting a higher data rate beyond a 4G network or LTE system. A method according to the present invention comprises the steps of: determining the number of blocks and a window size for configuring a transmission period for sliding window superposition coding (SWSC); transmitting control information including the determined number of blocks and window size to a plurality of terminals participating in the SWSC; transmitting, in a first block within the transmission period, a signal in which a first message and a second message are superposition-coded by first and second codes; and when a message notifying that the first message is not successfully decoded is received, transmitting, in a second block, a signal in which the second message and the first message are superposition-coded by the first and second codes.
