Method and apparatus for transmit signal power control and discovery signal resource multiplexing in wireless communication system

A method performed by a base station in a communication system, the method comprising:

• identifying one or more discovery resources and corresponding time and frequency resource information and threshold information associated with a reception signal power for selecting a discovery resource for transmitting a discovery signal;
• and
• transmitting, to a terminal, configuration information for the one or more discovery resources, the configuration information including time and frequency resource information and threshold information for each of the one or more discovery resources,
• wherein the discovery resource is selected among the one or more discovery resources based on a reception signal power measured by the terminal and the threshold information, and
• wherein the discovery signal is transmitted using the selected discovery resource.

A terminal in a communication system, the terminal comprising:

• a transceiver;
• and
• a controller coupled with the transceiver and configured to:
• receive, from a base station via the transceiver, configuration information for one or more discovery resources, the configuration information including time and frequency resource information and threshold information for a reception signal power for each of the one or more discovery resources,
• measure reception signal power,
• select a discovery resource among the one or more discovery resources based on the measured reception signal power and the threshold information, and
• transmit a discovery signal using the selected discovery resource.
