摘要： A technique for receiving and transmitting downlink reference signals is disclosed. When transmitting downlink data demodulation reference signals (DMRS) (or reference signals for downlink data demodulation) by using two or more layers, the DMRS of each layer may be multiplexed by using a code division multiplexing method and then transmitted. The DMRS for each of the two or more layers may be used for one user equipment or for two or more user equipments. And, downlink control signals for transmitting and receiving such DMRS may be configured to have the same format regardless of a single-user mode (or SU-MIMO mode) or a multi-user mode (or MU-MIMO mode), thereby being used.

摘要： A mode adaptation method for performing mode switching between a single-user MIMO (SU-MIMO) mode and a multi-user MIMO (MU-MIMO) mode includes reporting, by a base station, a MIMO feedback mode to a mobile station, receiving a feedback information determined on the basis of the MIMO feedback mode from the mobile station; and determining a MIMO feedback mode based on the feedback information. The MIMO feedback mode indicates whether it is single-user MIMO or multi-user MIMO and includes a number of mobile stations (MSs) transferred at one time. As a result, the method maximizes a system throughput simultaneously while effectively reducing an amount of feedback information.

摘要： A method of transmitting feedback information in a multiple antenna system is provided. The method includes selecting at least one subband selected from a plurality of subbands according to subband preset information, the subband preset information being a preset on data processing settled for each of the plurality of subbands, and transmitting a subband index of the selected subband. Only a subband index is fed back instead of separately transmitting a precoder index or a modulation and coding scheme (MCS) level index to each UE, thereby reducing feedback overhead.
