Abstract: A method performed by a user equipment (UE) in a wireless communication system is provided. The method includes transmitting, to a base station, capability information of the UE, and receiving configuration information associated with a transport block size (TBS). The TBS is determined based on a value of NRE·R·Qm·v. The NRE corresponds to a number of allocated resource elements, the R corresponds to a code rate, and the Qm corresponds to a modulation order, and the v corresponds to a number of allocated layers. A maximum value of the TBS is considered for transport block over multiple slots (TBoMS), and the maximum value of the TBS is determined by limiting at least one of a value of the NRE, the R, the Qm, or the v.

Abstract: Disclosed is a 5th generation (5G) or a pre-5G communication system for supporting a data transmission rate higher than that of a 4th generation (4G) communication system such as long term evolution (LTE). An apparatus and a method for performing retransmission in a wireless communication system are provided. A method for operating a transmitting device in a wireless communication system, according to various embodiments of the present disclosure, comprises the steps of: transmitting a plurality of data code blocks (CBs) to at least one receiving device in an initial transmission step; receiving, from the at least one receiving device, feedback information including information for indicating the number of data CBs, from among the plurality of data CBs, for which decoding has failed; and transmitting the number of parity CBs, determined on the basis of the number of data CBs for which the decoding has failed, to the at least one receiving device in a retransmission step. Therefore, the resources required for retransmission can be reduced.
