Abstract
Methods and apparatuses are provided for transmitting and receiving information. A User Equipment (UE) identifies a sequence based on a Zadoff-Chu sequence and ejα, where a cyclic shift value α is defined per cell. The UE identifies information for an orthogonal sequence. The UE generates a signal by using the information, the sequence and the orthogonal sequence. The UE transmits the signal in a Single Carrier-Frequency Division Multiple Access (SC-FDMA) symbol to a Node B.
Claims20
A method for transmitting information, the method comprising:
- identifying, by a User Equipment (UE), a sequence based on a Zadoff-Chu sequence and ejα, where a cyclic shift value α is defined per cell;
- identifying, by the UE, information for an orthogonal sequence;
- generating, by the UE, a signal by using the information, the sequence and the orthogonal sequence;
- and
- transmitting, by the UE, the signal in a Single Carrier-Frequency Division Multiple Access (SC-FDMA) symbol to a Node B.
A method for receiving information, the method comprising:
- receiving, by a Node B, a signal in a Single Carrier-Frequency Division Multiple Access (SC-FDMA) symbol to a Node B;
- determining, by the Node B, a sequence based on a Zadoff-Chu sequence and ejα, where a cyclic shift value α is defined per cell;
- determining, by the Node B, information for an orthogonal sequence;
- and
- obtaining, by the Node B, the signal by using the information, the sequence, and the orthogonal sequence.
