Method and apparatus for performing communication by D2D communication terminal

A method of a base station in a wireless communication system, the method comprising:

• identifying one or more discovery resource pools and a number of a repetitive transmission of a discovery signal for each of the one or more discovery resource pools of a terminal;
• and
• transmitting configuration information on a discovery resource pool to the terminal, the configuration information on the discovery resource pool including resource information for each of the one or more discovery resource pools and information on the number of the repetitive transmission configured for each of the one or more discovery resource pools,
• wherein the discovery signal is transmitted on a discovery resource for respective discovery signal transmission, and
• wherein the discovery resource for respective discovery signal transmission is identified based on a predefined pattern and information on the number of the repetitive transmission for a discovery resource pool,
• wherein information related to a transmission power corresponding to each of the one or more discovery resource pools is included in the configuration information on the discovery resource pool.

A terminal in a wireless communication system, the terminal comprising:

• a transceiver;
• and
• a controller coupled with the transceiver and configured to:
• receive configuration information on a discovery resource pool from a base station, the configuration information on the discovery resource pool including resource information for each of one or more discovery resource pools and respective information on a number of a repetitive transmission configured for each of the one or more discovery resource pools,
• identify a discovery resource for respective discovery signal transmission in a discovery resource pool based on information on the number of the repetitive transmission for the discovery resource pool and a predefined pattern, and
• transmit a discovery signal on the discovery resource,
• wherein information related to a transmission power corresponding to each of the one or more discovery resource pools is included in the configuration information on the discovery resource pool.
