Method for transmitting control information and base station, and method for receiving control information and user equipment

摘要

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.

1. A method of receiving, by a user equipment, downlink data, the method comprising:
decoding, by the user equipment, at least a first or second downlink control channel carrying downlink control information for the downlink data in a downlink subframe; and receiving, by the user equipment, the downlink data for the user equipment in a data region of the downlink subframe based on the decoded downlink control channel, wherein the downlink subframe is divided into a common control region and the data region in a time domain, wherein the first downlink control channel is received in the common control region, and the second downlink control channel is received in a control region configured within the data region, and wherein the second downlink control channel is decoded using a demodulation reference signal associated with the second downlink control channel, the demodulation reference signal being received within the control region.
