Abstract: A method for transmitting a reference signal by a user equipment (UE) in a wireless communication system. The UE generates an uplink reference signal in a subframe comprising first, second, third, fourth, fifth, sixth and seventh orthogonal frequency division multiplexing (OFDM) symbols in time domain and a plurality of subcarriers in frequency domain. The UE transmits the uplink reference signal to a base station in the third, fourth and fifth OFDM symbols. The transmitted uplink reference signal is hopped in the frequency domain, based on a cell specific hopping parameter.

Abstract: Provided is a method for transmitting, by a user equipment (UE), a demodulation reference signal (DMRS) for a physical uplink shared channel (PUSCH) in a wireless communication system. A terminal receives a cyclic shift field, which indicates a first value and a second value, through a physical downlink control channel (PDCCH) from a base station, generates a first DMRS sequence and a second DMRS sequence, which are associated with a first layer and a second layer respectively, by using a first cyclic shift and a second cyclic shift, respectively, which are determined based on the first value and the second value respectively, and transmits the first DMRS sequence and the second DMRS sequence to the base station. Furthermore, the first value and the second value are separated by a maximum value corresponding to a total number of possible cyclic shifts.

Abstract: A method and a user equipment (UE) are provided for transmitting uplink data in a wireless communication system. Uplink data is mapped to resource elements corresponding to a physical uplink shared channel (PUSCH) in a UE-specific aperiodic sounding reference signal (SRS) subframe. The UE-specific aperiodic SRS subframe includes a single carrier frequency division multiple access (SC-FDMA) symbol reserved for an aperiodic SRS. The aperiodic SRS is transmitted in the reserved SC-FDMA symbol when triggered by a base station. The uplink data is not mapped to the SC-FDMA symbol reserved for the aperiodic SRS regardless of whether the aperiodic SRS is transmitted in the reserved SC-FDMA symbol or not. The mapped uplink data is transmitted to the base station via the UE-specific aperiodic SRS subframe.

Abstract: A method and apparatus for transmitting or detecting primary synchronization signal. The receiver receives primary synchronization signal from a transmitter, and detects the sequence used in the received primary synchronization signal by using three root indexes. Here, the primary synchronization signal is generated by using a Zadoff-Chu sequence having one of the three root indexes. The three root indexes comprise a first index and a second index, and a sum of the first index and the second index corresponds to the length of the Zadoff-Chu sequence.
