Abstract
The invention claims a method for receiving and transmitting a downlink reference signal technology. when by using two or more layers to transmit downlink data demodulation reference signal (DMRS) (or for downlink data demodulation reference signal) the DMRS of each layer can be by using a code division multiplexing method are multiplexed and then transmitted. for each of the DMRS in two or more layers can be used for one user equipment or for two or more user equipment. and no single user mode (or SU-MIMO mode) or multiple-user mode (or MU-MIMO mode) for transmitting and receiving the DMRS of downlink control signal may be configured to have the same format so as to be used.
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.
