Abstract: The present disclosure relates to a communication technique for combining a 5G communication system that supports higher data transmission rates after 4G systems with IoT technology and to the system therefor. The present disclosure can be applied for intelligent services based on 5G communication technology and IoT related technology (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail businesses, security and safety related services, and the like). A method for determining an uplink transmission resource of a wireless communication system comprises the steps of: obtaining one or more of first distance information between a first base station supporting a first communication system and a terminal supporting the first communication system, and second distance information between a second base station supporting a second communication system and the terminal; and determining a frequency resource and transmission power for uplink signal transmission of the first terminal based on one or more of the obtained first distance information and second distance information.

Abstract: Disclosed is a method and apparatus for transmitting information in a communication system. The present invention relates to a millimeter wave beamforming-based 5G or pre-5G wireless communication system for supporting a higher data rate beyond a 4G network or LTE system. A method according to the present invention comprises the steps of: determining the number of blocks and a window size for configuring a transmission period for sliding window superposition coding (SWSC); transmitting control information including the determined number of blocks and window size to a plurality of terminals participating in the SWSC; transmitting, in a first block within the transmission period, a signal in which a first message and a second message are superposition-coded by first and second codes; and when a message notifying that the first message is not successfully decoded is received, transmitting, in a second block, a signal in which the second message and the first message are superposition-coded by the first and second codes.
