METHOD AND APPARATUS FOR TRANSMITTING MULTI-USER MIMO REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEM FOR SUPPORTING RELAY |
摘要 |
<p>The present invention relates to a wireless communication system, and more particularly to a method and an apparatus for transmitting a multi-user Multiple Input Multiple Output (MIMO) signal in a wireless communication system for supporting a relay. A method for transmitting a demodulation reference signal (DMRS) for downlink multi-user MIMO transmission according to an embodiment of the present invention comprises the steps of: mapping a DMRS for a first layer on a downlink physical resource block according to a first DMRS pattern; mapping a DMRS for a second layer on the downlink physical resource block according to a second DMRS pattern; and transmitting the downlink physical resource block. In the downlink physical resource block, a resource element corresponding to the second DMRS pattern can be punctured on the first layer and a resource element corresponding to the first DMRS pattern can be punctured on the first layer and a resource element corresponding to the first DMRS pattern can be punctured on the second layer.</p> |
