Abstract: According to one aspect of the present invention, antennas or antenna nodes spaced away from each other by a predetermined distance or more are configured to be able to transmit control information of mutually different user equipment groups, thereby increasing the efficiency in the operation of control channels. In addition, according to another aspect of the present invention, a resource region for transmitting control information for an improved user equipment, which is a target of a multi-node cooperative transmission, is set differently from a resource region for transmitting control information for a legacy user equipment, thereby increasing the efficiency in the transmission of the control information for the improved user equipment.

Abstract: A method is provided for receiving aperiodic channel state information (CSI). A base station (BS) transmits, to a user equipment (UE), an uplink downlink control information (DCI) format. The BS receives, from the UE, aperiodic CSI through a physical uplink shared channel (PUSCH) if the BS triggers an aperiodic CSI report using a CSI request field included in the uplink DCI format. The CSI request field is either a 1-bit field or a multi-bit field. When the UE is configured with only one cell, the 1-bit field is included in the uplink DCI. When the UE is configured with more than one channel state information-reference signal (CSI-RS), the multi-bit field is included in the uplink DCI.

Abstract: A method is presented for receiving aperiodic channel state information (CSI). A base station (BS) transmits a CSI request field which is set to trigger a CSI report to a user equipment (UE). The BS receives CSI through a physical uplink shared channel (PUSCH) from the UE. The CSI request field has a value among a plurality of candidate values. The plurality of candidate values comprises a first value which triggers an aperiodic CSI report for a first set of reference signals and a second value which triggers an aperiodic CSI report for a second set of reference signals.

Abstract: A method of performing cooperative transmission in a multi-node system including a Base Station (BS) and a plurality of nodes controlled by the BS is provided. The method comprises: transmitting a first signal generated using a first cell identifier (ID) from the plurality of nodes; and transmitting a second signal generated using a second cell ID from at least one of the plurality of nodes, wherein the first cell ID is identical with a cell ID used by the BS, and the second cell ID is different from the first cell ID.
