    摘要: A method and apparatus of feeding back channel state information in a multi-node system are provided. The method includes receiving a reference signal of N nodes, wherein N is a natural number equal to or more than 2, aligning the N nodes in an order of preferring the N nodes based on a result of measuring the reference signal, generating channel state information for the aligned nodes, and transmitting the generated channel state information to the base station, wherein the channel state information is generated with respect to N node combinations configured from the aligned nodes, and wherein the N node combinations are obtained by adding next highest-priority nodes to a first node combination one by one, the first node combination consisting a highest-priority node among the aligned nodes.

    摘要: A method of performing a handover in a wireless communication system employing a macro base station and a femto base station is provided. The method comprising: monitoring an uplink signal transmitted from a user equipment to the macro base station; transmitting a handover initiation message to the macro base station on the basis of a result of comparing the uplink signal's strength obtained by the monitoring with a reference value; and performing a handover of the user equipment from the macro base station to the femto base station. According to the present invention, there is provided a method of initiating a handover by a femto base station by fining user equipments located in a cell coverage of the femto base station. In addition, a signaling overhead is reduced by utilizing previously existing information such as uplink transmit power.
