Abstract
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

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.
A method for receiving control information in a single carrier-frequency division multiple access (SC-FDMA) system, comprising:
- receiving, by a node B, a control channel signal from a user equipment (UE);
- determining, by the node B, cyclic shift values for SC-FDMA symbols;
- acquiring, by the node B, cyclic shift sequences by the cyclic shift values;
- and
- acquiring, by the node B, the control information by applying the cyclic shift sequences to the received control channel signal.
