Abstract: A transmit power control method of a terminal in direct communication between terminals is disclosed. The terminal measures a path loss gain of a base station, and compares the measured path loss gain with a predetermined threshold value. The terminal sets a power value for direct communication in the case in which the measured path loss gain is less than or equal to the predetermined threshold value, and performs the direct communication at the set power value.

Abstract: Disclosed is a method for configuring a bandwidth for supporting a broadband carrier in a communication system. An operation method of a base station comprises the steps of: configuring a first bandwidth part and a second bandwidth part for a terminal; configuring a reserved resource for the first bandwidth part in a resource area in which the first bandwidth part and the second bandwidth part overlap; and performing an operation of transmitting or receiving a second data channel, which is scheduled to the second bandwidth part, together with the terminal by using the reserved resource. Therefore, the performance of the communication system can be improved.
