METHOD FOR TRANSMITTING COMMON REFERENCE SIGNAL IN DOWNLINK MIMO SYSTEM |
摘要 |
The present invention relates to a method for transmitting a reference signal (RS) for measuring a channel in a downlink MIMO (Multi Input Multi Output) system that supports: a first user device supporting N base station transmission antennas out of a total of M base station transmission antennas and a second user device supporting M (M > N) base station transmission antennas. The method comprises the steps of: grouping a certain number of subframes or a resource block (RB) to transmit a common reference signal (CRS) for M transmission antennas from the base station; and transmitting the subframes or the resource block to the second user device. The grouped subframes or the resource block are transmitted to the second user terminal in a specific time period, and in the subframes or the resource block, the common reference signal is mapped to different transmission antennas ports corresponding to a quotient which is obtained by dividing M by a specific number. |
