METHOD AND APPARATUS FOR PROVIDING DOWNLINK CONTROL INFORMATION IN AN MIMO WIRELESS COMMUNICATION SYSTEM |
摘要 |
The present invention relates to a method in which a user equipment receives a downlink signal from a base station in a wireless communication system that supports downlink MIMO transmission according to one embodiment of the present invention comprises: receiving downlink control information that includes information indicative of the number of layers (N, 1≦̸N≦̸8) where one or two enabled code words of the downlink MIMO transmission are mapped; on the basis of the downlink control information, receiving downlink data transmitted over the respective N layers and a UE-specific reference signal for each of the N layers; and decoding the downlink data on the basis of the UE-specific reference signals, wherein the information indicative of the number of layers can further include information on a code for identifying the UE-specific reference signals.
