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 for transmitting a signal by a transmitting side device, the method including combining a first sequence and a second sequence to generate a third sequence in a frequency domain. The second sequence is obtained by cyclic shifting the first sequence. The method further includes transforming the third sequence into a time domain signal; and transmitting the time domain signal to a receiving side device. The third sequence includes information to identify a cell and is periodically transmitted.

Abstract: Disclosed are a terminal device for controlling uplink transmission power and a method therefor. A receiving antenna receives uplink transmission mode change information from a base station. A processor determines a transmission power value to be used for the uplink transmission by means of an offset value corresponding to the uplink transmission mode change information. A transmitting antenna transmits an uplink signal with the determined transmission power value.

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).
