Abstract:
Methods and apparatuses are provided for transmitting and receiving information. A User Equipment (UE) receives information for a cyclic shift value and information for an orthogonal sequence transmitted from a Node B. The cyclic shift value is defined per Single Carrier-Frequency Division Multiple Access (SC-FDMA) symbol and the orthogonal sequence is defined per slot. The UE obtains a reference sequence based on the cyclic shift value and the orthogonal sequence. The UE transmits the reference sequence in a SC-FDMA symbol to the Node B. The SC-FDMA symbol is predefined among a plurality of SC-FDMA symbols in a slot of a subframe.
