METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING CONTROL INFORMATION TO RANDOMIZE INTER-CELL INTERFERENCE IN A MOBILE COMMUNICATION SYSTEM

摘要

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.

1. A method for transmitting information, the method comprising:
receiving, by a User Equipment (UE), 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; obtaining, by the UE, a reference sequence based on the cyclic shift value and the orthogonal sequence; and transmitting, by the UE, the reference sequence in a SC-FDMA symbol to the Node B, wherein the SC-FDMA symbol is predefined among a plurality of SC-FDMA symbols in a slot of a subframe.
