Patent Images
1. A method for enhancing a small cell, which is performed by a terminal applying inter-site carrier aggregation (CA), the method comprising:
- transmitting uplink control information regarding at least one of macro cells managed by a macro cell base station through the macro cell; and
transmitting uplink control information regarding at least one of small cells managed by a small cell base station through the small cell.

Abstract
Disclosed is a method for enhancing a small cell. A method for enhancing a small cell in a terminal applying inter-site CA includes the steps of: causing a terminal to transmit the uplink control information (UCI) of at least one of the macro cells controlled by a macro cell base station through the macro cell; and causing the terminal to transmit the uplink control information of at least one of the small cells controlled by a small cell base station through the small cell.
