METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING CONTROL NFORMATION IN A WIRELESS COMMUNICATION SYSTEM

摘要

In a wireless communication system according to the present invention, a first base station (BS) receives information related to a signal transmitted by a second BS, which is adjacent to the first BS, determines whether a second user equipment (UE), which uses the same resources as a first UE included in the first BS, exists within the second BS based on the received information, generates information for decoding a signal which the adjacent BS transmits to the second UE as control information based on the received information, and transmits the generated control information to the first UE by using a common area of a control channel area.
