Abstract
A communication method comprises a communication apparatus managing a serving cell of a user terminal and broadcasting to the user terminal system information for Device to Device (D2D) proximity service using a frequency of the serving cell. The user terminal performing a discovery procedure to discover another user terminal on a basis of the system information, which includes first information that indicates an available frequency for the discovery procedure different from the frequency of the serving cell and related to a center frequency of a frequency band of the available frequency, second information that indicates at least one parameter for calculating transmission power for the discovery procedure, third information that indicates a Public Land Mobile Network (PLMN) identifier for the available frequency, and fourth information that indicates number of times of re-transmissions of a discovery signal to be re-transmitted by one user terminal in the discovery procedure.
