1. A method for small cell discovery and user equipment discovery, the method comprising: obtaining, by circuitry of a user equipment, small cell information regarding small cell discovery on a macro layer; obtaining, by the circuitry, user equipment information regarding user equipment discovery; determining, by the circuitry, whether the user equipment information includes all first parameters necessary for performance of standalone user equipment discovery without the small cell information; building the first parameters for user equipment discovery, by the circuitry when the circuitry determines that the user equipment information does not include all of the first parameters necessary for the performance of standalone user equipment discovery, based on second parameters included in the small cell information, the second parameters being parameters for performance of the small cell discovery; initiating, by the circuitry, user equipment discovery based on the first parameters; and initiating, by the circuitry, small cell discovery based on the second parameters.
