Abstract
A code word selection method performed by a User Equipment (UE) in a wireless communication system is provided. The method includes generating a rotation matrix using previously selected codeword; generating a new differential code book using the rotation matrix and a differential code book; selecting a code word from the new differential code book; and performing data transmission using the selected code word.
Claims6
A method for selecting a codeword by a User Equipment (UE) in a wireless communication system, the method comprising:
- generating a rotation matrix using a previously selected codeword;
- generating a new differential code book using the rotation matrix and a differential code book;
- selecting a code word from the new differential code book;
- and
- performing data transmission using the selected code word.
A method for selecting a code word by an enhanced Node B (eNB) in a wireless communication system, the method comprising:
- generating a rotation matrix using a previously selected codeword;
- generating a new differential code book using the rotation matrix and a differential code book;
- selecting a code word from the new differential code book;
- and
- performing data transmission using the selected code word.
