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: An operation method of a terminal in a communication system may comprise: receiving, from a base station, basis preamble information and linear combination information; generating a superposed preamble by using the basis preamble information and the linear combination information; transmitting, to the base station, a first message including the generated superposed preamble; and receiving, from the base station, a second message that is a response signal for the first message.

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.
