Abstract: Disclosed are a method and a device for transmitting uplink control information (UCI) by a terminal in a wireless communication system. The UCI transmission method comprises the steps of: generating an encoding information bit stream by performing channel coding for a UCI bit stream; generating complex modulation symbols by performing modulation for the generated encoding information bit stream; spreading the complex modulation symbols in block-wise on the basis of an orthogonal sequence; and transmitting the spread complex modulation symbols to a base station. The encoding information bit stream is generated by a channel coding for circularly repeating the UCI bit stream.

Abstract: Method for generating reference signal sequence using grouping is explained. In this method, base sequences are grouped such that each group contains at least one base sequence of each length, so UE(s) can use various length sequences as a reference signal. And in this method, inter cell interference caused by using various length sequence as a reference signal sequence can be minimized by grouping sequences having the high cross correlation relation.

Abstract: A method of allocating control information in a wireless communication system is provided. The method includes: allocating essential control information of a first system to a first sub-frame in a frame including a plurality of sub-frames each of which comprises a plurality of orthogonal frequency-division multiplexing (OFDM) symbols; and allocating essential control information of a second system to an nth sub-frame in a fixed position from the first sub-frame (where n is an integer satisfying n>1). Accordingly, in a frame supporting heterogeneous systems, essential control information can be fixedly allocated to a specific position while maintaining the number of system switching points, at which switching occurs between the systems, to one even if a radio resource allocation amount changes between the systems, and thus the essential control information that must be received by all user equipments can be effectively provided without the increase of overhead.

Abstract: A method is provided 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. The Node-B transmits a random access procedure configuration including a basic sequence index related with a random access channel and zero correlation zone (ZCZ) configuration. The Node-B receives a random access preamble corresponding to the random access procedure configuration from the UE over the random access channel. A length of a cyclic part and a length of a sequence part of the random access preamble are differently given based on the random access procedure configuration. The random access preamble is generated from Constant Amplitude Zero Auto-Correlation (CAZAC) sequences based on the basic sequence index by applying a length of a cyclic shift according to the ZCZ configuration.
