摘要： The objective of the present invention is to provide services by effectively switching, by a terminal, a macro cell and a small cell on the basis of time in a communication system in which the macro cell and the small cell coexist. A method for operating a terminal in a wireless communication system comprises the steps of: transmitting, to a first base station and/or a second base station, information on a switching delay time required for the terminal to perform cell switching; and communicating through a resource of the first base station and a resource of the second base station which are allocated by considering the switching delay time.

摘要： The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method for communicating by a user equipment with a macro cell base station and a small cell base station in a communication system is provided. The method comprises applying a first base station security key to a first communication link with the macro cell base station; generating a second base station security key to be used for a second communication link with the small cell base station based on the first base station security key; applying the second base station security key to the second communication link with the small cell base station; and communicating through at least one of the first communication link and the second communication link.
