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) identifies first information for a cyclic shift value, transmitted from a Node B. The UE identifies second information for the cyclic shift value, transmitted from the Node B. The UE obtains a sequence based on a Zadoff-Chu sequence and the cyclic shift value defined based on the first information and the second information. The UE transmits the sequence in a Single Carrier-Frequency Division Multiple Access (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:
identifying, by a User Equipment (UE), first information for a cyclic shift value, transmitted from a Node B; identifying, by the UE, second information for the cyclic shift value, transmitted from the Node B; obtaining, by the UE, a sequence based on a Zadoff-Chu sequence and the cyclic shift value defined based on the first information and the second information; and transmitting, by the UE, the sequence in a Single Carrier-Frequency Division Multiple Access (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.
