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 control information in an SC-FDMA system. A UE determines cyclic shift values for SC-FDMA symbols. The UE acquires cyclic shift sequences by the cyclic shift values. The UE applies the cyclic shift sequences to the control information on an SC-FDMA symbol basis. The control information applied with the cyclic shift sequences in the SC-FDMA symbols is transmitted to a Node B

1. A method for transmitting control information in a single carrier-frequency division multiple access (SC-FDMA) system, comprising:
determining, by a user equipment (UE), cyclic shift values for SC-FDMA symbols; acquiring, by the UE, cyclic shift sequences by the cyclic shift values; applying, by the UE, the cyclic shift sequences to the control information on an SC-FDMA symbol basis; and transmitting the control information applied with the cyclic shift sequences in the SC-FDMA symbols to a Node B.
