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 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. System information is transmitted for at least one of a basic sequence index and a length of a zero correlation zone (ZCZ) to the specific UE. A preamble sequence is received from the specific UE over a random access channel. The preamble sequence is generated from Constant Amplitude Zero Auto-Correlation (CAZAC) sequences distinguishable by at least one of the basic sequence index and a length of a Cyclic Shift (CS) applied to the preamble sequence. The length of the CS applied to the preamble sequence is given by one among a plurality of application lengths determined based on the length of the ZCZ. A number of the plurality of lengths are differently given based on a type of the specific UE.

Abstract: A method is described for receiving a physical signal by a communication apparatus in a wireless communication system supporting carrier aggregation of a first component carrier and a second component carrier. The communication apparatus receives a physical downlink control channel (PDCCH) signal on the first component carrier. The communication apparatus also receives a physical downlink shared channel (PDSCH) signal corresponding to the PDCCH signal on the second component carrier. The first component carrier is different from the second component carrier. A starting orthogonal frequency division multiplexing (OFDM) symbol for receiving the PDSCH signal is determined according to information received via a radio resource control (RRC) signal.
