Abstract: An operation method of a receiving node may include performing a decoding operation for calculating first and second output transform values corresponding to first and second unit output nodes in each of a plurality of operation units constituting the polar decoder, based on first and second input transform values corresponding to first and second unit input nodes, and the decoding operation may include setting initial values of first and second variables for calculating the first output transform value; performing an iterative loop operation for updating the first and second variables; and calculating the first output transform value based on values of the first and second variables updated until a time when the iterative loop operation is terminated, wherein the iterative loop operation is terminated without performing iterations in which the first and second variables are determined not to be updated among a plurality of iterations.

Abstract: Disclosed is an apparatus and method for detecting a code. The code detecting apparatus may include a detector to detect symbol synchronous timing information associated with a PSS code from a first signal received during a predetermined first period, a compensator to extract and buffer the PSS code and the SSS code based on the symbol synchronous timing information detected from a second signal received during a predetermined second period, and compensate for a frequency offset with respect to the buffered PSS code, and a processor to re-detect the symbol synchronous timing information based on the PSS code in which the frequency offset is compensated for, and extract the buffered SSS code using the re-detected symbol synchronous timing information.

Abstract: Disclosed are methods and apparatuses for transmitting data using a random access procedure in a communication system. An operation method of a terminal in a communication system includes transmitting a first MsgA including an RA preamble #i and a payload to a base station; receiving, from the base station, a MsgB including information indicating that an RA preamble #k is reserved; and transmitting a second MsgA including the RA preamble #k and data to the base station in a preamble reservation period associated with the RA preamble #k.
