Method for reducing overhead of control signal on the LTE dual connectivity

摘要

The present invention relates to a method of a terminal effectively transmitting a control signal when a small cell base station and a macro cell base station applied to a small cell cluster environment are serviced in a heterogeneous network at the same time. The present invention relates to a method for reducing overhead of the control signal on LET dual connectivity capable of greatly reducing or summing the control signal transmission frequency of a terminal for a small cell station.
