Abstract
A communication method comprises: broadcasting, from a communication apparatus to a user terminal, system information for Device to Device (D2D) proximity service, by use of a frequency of a serving cell of the user terminal, the communication apparatus managing the serving cell. The system information includes first information and second information. The first information indicates an available frequency for a discovery procedure in which the user terminal discovers another user terminal. The second information indicates at least one parameter for calculating transmission power for the discovery procedure. The available frequency for the discovery procedure is a frequency different from the frequency of the serving cell. The first information is related to a center frequency of a frequency band of the available frequency for the discovery procedure.
