Abstract: A method is provided for demodulating a signal. A relay node receives control information, from an evolved-NodeB (eNB), through a relay-physical downlink control channel (R-PDCCH), and receives a data, from the eNB, through a physical downlink shared channel (PDSCH). When a number of transmission layers of the PDSCH is 2 or more than 2 and a plurality of reference signals for a demodulation of the data are transmitted on antenna ports by the eNB, a reference signal transmitted on a minimum antenna port among the antenna ports is used for a demodulation of the control information.

Abstract: A method is provided for performing a random access procedure by a Node-B with a specific user equipment (UE) within a cell in which a plurality of UEs are located together. The Node-B transmits a random access procedure configuration including a basic sequence index related with a random access channel and zero correlation zone (ZCZ) configuration. The Node-B receives a random access preamble corresponding to the random access procedure configuration from the UE over the random access channel. A length of a cyclic part and a length of a sequence part of the random access preamble are differently given based on the random access procedure configuration. The random access preamble is generated from Constant Amplitude Zero Auto-Correlation (CAZAC) sequences based on the basic sequence index by applying a length of a cyclic shift according to the ZCZ configuration.

Abstract: A base station apparatus for transmitting a reference signal in a wireless communication system is provided in which a processor generates the same sequence for resource elements (REs) allocated to each layer for reference signal transmission and spreads or covers Walsh codes for a user equipment-specific reference signal sequence such that sequences generated for the REs can be orthogonal to each other on a time axis. The Walsh code spreading or covering by the processor is applied on a frequency axis based on a plurality of resource blocks (RBs) or based on a pair of RBs such that mutually different sequences having mutually different sequence values can be mapped between RBs or between pairs of RBs. A transmission module transmits the reference signal, to which the generated reference signal sequence is applied to user equipment via each layer.
