    Abstract: An operation method of a terminal may include: receiving, from a base station, an addition value KN, information on linear combination coefficient matrices for respective numbers of transport blocks, and configuration information on each linear combination coefficient matrix; dividing a source block into M transport blocks; selecting one linear combination coefficient matrix among the linear combination coefficient matrices based on M; generating (M+KN) network coding blocks by performing network coding on the M transport blocks with the selected one linear combination coefficient matrix; and transmitting, to the base station, messages each including one network coding block among the network coding blocks, a control index of the one linear combination coefficient matrix, and a preamble.

    Abstract: A LDPC encoding method is provided, which is highly scalable and may support a variety of code cases and allow a high processing speed. The LDPC encoding includes: receiving an information sequence to be encoded; segmenting the information sequence into blocks of a predetermined length; deriving parity bits for each of the segmented blocks by using a predetermined parity check matrix; and generating a codeword by combining the parity bits into a corresponding segmented block. The operation of deriving parity bits for each of the segmented blocks includes: performing multiplications with at least one element of the parity check matrix by circularly shifting the segmented block a number of times corresponding to the at least one element of the parity check matrix; and performing XOR operations on a plurality of bits of a circularly-shifted segmented block in parallel.

    Abstract: An operation method of a terminal may comprise receiving, from a base station, information of target transmission points targeted for a report of first channel state information (CSI) among the plurality of transmission points; receiving a first CSI-reference signal (CSI-RS) from the target transmission points; transmitting the first CSI determined based on the first CSI-RS to the base station; receiving, from the base station, information on a first transmission point determined based on the first CSI; receiving, from the first transmission point indicated by the information on the first transmission point, a second CSI-RS; receiving, from the base station, information on a requirement; and transmitting, to the base station, a second CSI including a transmission parameter for achieving the requirement.
