Abstract: The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting higher data transmission rates than 4th generation (4G) communication systems such as long term evolution (LTE). A method performed by a first base station in a wireless communication system includes: identifying a first signal-to-interference-noise ratio (SINR), based on channel state information received from a terminal; identifying a modulation and coding scheme (MCS), based on the first SINR and information on a link direction of a second base station; and transmitting information indicating the MCS to the terminal.

Abstract: A method for selecting a serving cell by a user equipment (UE) to which the inter-site carrier aggregation (CA) technology is according to the intensity of a reception signal of each carrier wave is provided. However, in order to improve resource usage and a throughput of the entire cells, a method is performed in which a PCell and an SCell are selected considering the intensity of a reception signal and a load between cells, the SCell is activated, and loads of the PCell and the SCell are adjusted. The method can balance an inter-cell traffic load, and eventually, increase usage of the entirety of a network and improve a throughput.
