Abstract: A method and a user equipment (UE) for transmitting an aperiodic sounding reference signal (SRS) in a wireless communication system are discussed. The method according to an embodiment includes receiving an aperiodic SRS power offset parameter for the aperiodic SRS from a base station (BS) through a radio resource control (RRC) signaling; receiving common parameters for SRSs, including the aperiodic SRS, from the BS through the RRC signaling; setting a transmission power of the aperiodic SRS based on the aperiodic SRS power offset parameter and the common parameters; and transmitting the aperiodic SRS to the BS based on the transmission power of the aperiodic SRS. The aperiodic SRS power offset parameter is a non-common parameter used for transmitting the aperiodic SRS but not a periodic SRS which is included in the SRSs.

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.

Abstract: A method and a user equipment (UE) for transmitting control information in a wireless communication system are discussed. The method according to one embodiment includes receiving a parameter which indicates whether transmission of a hybrid automatic repeat request acknowledgement (HARQ-ACK) on a physical uplink control channel (PUCCH) and a sounding reference signal (SRS) in one subframe is configured; if the parameter is true, transmitting, in a primary component carrier (CC), the PUCCH, which coincides in a same subframe as the SRS, by using a shortened PUCCH format carrying at least one of the HARQ-ACK and a positive scheduling request (SR); and if the parameter is false, transmitting the PUCCH by using a normal PUCCH format, while not transmitting, in a secondary CC, the SRS which coincides in the same subframe as the PUCCH. The shortened PUCCH format is a shortened PUCCH format 1/1a/1b or a shortened PUCCH format 3.

Abstract: A method for transmitting a synchronization signal by a transmitting side device to a receiving side device in a wireless access system. The method includes generating a concatenated code sequence in a frequency domain by concatenating a first code sequence having a first index (M1) and a second code sequence having a second index (M2). Each of the first code sequence and the second code sequence is obtained by cyclic shifting a code sequence. The concatenated code sequence is mapped to subcarriers for transmitting the synchronization signal via a secondary synchronization channel (S-SCH). The method further includes transforming the concatenated code sequence into a time domain signal; and transmitting the time domain signal to the receiving side device as the synchronization signal. The concatenated code sequence indicates a cell group identity (ID).

Abstract: A method is provided for transmitting a demodulation reference signal (DMRS) by a user equipment (UE) in a wireless communication system.

Abstract: A method and a user equipment (UE) for generating a reference signal sequence in a wireless communication system are discussed. The method according to an embodiment includes receiving a cell-specific sequence hopping parameter from a base station. The cell-specific sequence hopping parameter is used to enable a sequence hopping for a plurality of UEs in a cell if a cell-specific group hopping parameter is used to disable a group hopping for the plurality of UEs in the cell. The method includes receiving a UE-specific sequence group hopping (SGH) parameter, specified to the UE, from the base station. The UE-specific SGH parameter is used to disable the sequence hopping, enabled by the cell-specific sequence hopping parameter. The method includes generating the reference signal sequence based on a base sequence number within a base sequence group. The base sequence number within the base sequence group is determined by the UE-specific SGH parameter.
