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.

Abstract: Provided is a control method for device-to-device (D2D) communication. A base station measures a load of a cell, receives location information about each piece of user equipment (UE) from a plurality of pieces of UE, selects any one of an overlay-based resource allocation method and an underlay-based resource allocation method on the basis of the measured cell load and the location information about the respective pieces of UE, allocates resources for D2D communication on the basis of the selected resource allocation method, and controls power according to the locations of the pieces of UE and a density of pieces of cellular communication UE. Accordingly, it is possible to improve resource use efficiency and efficiently remove interference.
