Abstract: A dynamic resource allocating apparatus of a first base station that manages a first cell in a cellular communication system including the first cell and a plurality of cells adjacent to the first cell determines time resource division vector in which one time resource division period is formed of a plurality of time division intervals and calculates time resource division vector for maximizing utilities of user terminals in a set up objective function to update the time resource division vector. Among the plurality of time division intervals, a first time division interval is operated by a time resource reuse coefficient 1 for user terminals positioned in center regions of a first cell and a plurality of adjacent cells, and the remaining time division intervals excluding the first time division interval are operated by a time resource reuse coefficient n for user terminals positioned at edges of the first cell and the plurality of adjacent cells.

Abstract: Disclosed are various methods for transmitting or receiving data or control information having high reliability conditions. A method for operating a terminal which transmits uplink control information (UCI) includes: a step of generating UCI; a step of comparing the priority of an uplink (UL) control channel for the transmission of the UCI with the priority of a UL data channel when some symbols of the UL control channel and the UL data channel overlap; and a step of selecting the UL channel having a higher priority among the UL control channel and the UL data channel, and transmitting the UCI to a base station through the selected UL channel.

Abstract: Disclosed are methods and apparatuses for transmitting and receiving data channels in a communication system. An operation method of a terminal in a communication system may comprise receiving, from a base station, resource allocation information of a plurality of physical uplink shared channels (PUSCHs) used for repetitive transmission of a same transport block (TB); identifying a position of each of the plurality of PUSCHs in a time domain based on the resource allocation information; and repeatedly transmitting the same TB to the base station at the position of each of the plurality of PUSCHs. Therefore, performance of the communication system can be improved.
