Abstract: An operation method of a first communication node in a communication system includes receiving one or more transport blocks (TBs) from a second communication node based on transmission parameters in an aggregated transmission period #n; generating decoding results for the one or more TBs; generating information required for changing the transmission parameters based on the decoding results; and transmitting the required information to the second communication node, wherein n is a natural number.

Abstract: Provided are a method and an apparatus for transmission and reception based on hybrid automatic repeat request in a communication system. A first communication node includes a coherent channel region (CCR) mapper configured to determine W representative soft bit values for each CCR on the basis of X original soft bit values of signals and determine a sign sequence of the X original soft bit values, and a CCR demapper configured to restore X soft bit values for each CCR using W representative soft bit values and a sign sequence. Since the CCR mapper compresses soft bits using channel coherency, a hybrid automatic repeat request (HARQ) buffer size is reduced compared to that of an existing method. Therefore, performance of a communication system may be improved.

Abstract: An operation method of a receiving node in a communication system includes: receiving, from a transmitting node, mapping information between transmission parameters and aggregation factors (AFs); receiving, from the transmitting node, control information including a first transmission parameter used for transmission of data among the transmission parameters; determining a first AF mapped to the first transmission parameter from among the AFs based on the mapping information; and performing a repetitive reception operation on the data transmitted from the transmitting node based on the first AF.

Abstract: A method and apparatus for modulating a baseband signal in beam space MIMO are provided. The baseband signal modulation apparatus may calculate a load value of a plurality of antenna elements using a baseband signal. The baseband signal modulation apparatus may change a phase or a magnitude of a baseband signal or a first band signal having a higher frequency than that of the baseband signal to correspond to the calculated load value.

Abstract: Methods and apparatuses for HARQ in a non-terrestrial network are disclosed. An operation method of a first node may comprise receiving a transport block (TB) from a second node; classifying total soft bits for the TB into information values and sign values; configuring the information values of the total soft bits into one or more subsets; performing a compression operation on each of the one or more subsets; and performing a compression operation on the sign values. Therefore, performance of the communication system can be improved.

Abstract: Provided are an uplink frequency control method and a terminal apparatus using the same. The uplink frequency control method includes measuring a frequency offset with respect to a downlink, deriving a frequency offset component with respect to an uplink through the measured frequency offset, and correcting an uplink frequency offset using the derived frequency offset component. Therefore, by controlling an uplink frequency through a simple operation in a terminal, baseband design of a base station can be simplified, and uplink SNR performance can be improved.
