UPLINK DEMODULATION REFERENCE SIGNAL DESIGN METHOD FOR TRANSMITTING DOWNLINK REFERENCE SIGNALS IN A WIRELESS COMMUNICATION SYSTEM

摘要

PURPOSE: An uplink demodulation reference signal design method is provided to allocate resource indexes corresponding to a reference signal mapped using a CSI(Cyclic Shift Indicator) filed by mapping reference signals corresponding to a sub set of antenna ports.;CONSTITUTION: A transmission route includes a CSI(Cyclic Shift Indicator) value which instructs an OCC(Orthogonal Cover Code) and a circulating shift. The transmission route includes a circuit for transmitting control information for uplink approval which allows the transmission route to transmit the control information in an uplink channel. A reception route includes a circuit for receiving one or more reference signals using an uplink channel corresponding to the circulating shift and the OCC.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) PUSCH allocation of UEO; (BB) SCs; (CC) SC-FDM symbols
