Abstract: The present invention relates to a wireless communication system, and more particularly, to a method and an apparatus for transmitting reference signals in uplink MIMO transmission. According to one embodiment of the present invention, the method for transmitting uplink signals through a terminal in the wireless communication system comprises the steps of: receiving control information including the information on a cyclic shift and/or an orthogonal cover code; allocating the multiplexed reference signals onto an uplink subframe; and transmitting the subframe through a multi-antenna. When the uplink MIMO transmission is multiuser MIMO transmission, the reference signals of the terminal and the reference signals of other terminals can be multiplexed by using the orthogonal cover code.

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 of mapping a physical resource to a logical resource in a wireless communication system is described. The method includes dividing a physical frequency band into at least one frequency partition. Each frequency partition is divided into a localized region and a distributed region in a frequency domain.
