Title:
チャネル品質情報の通信方式
Document Type and Number:
Japanese Patent JP5481523
Kind Code:
B2
Abstract:
The invention relates to a method for transmitting and a method for reconstructing channel quality information in a communication system. Further, the invention also provides a transmitter and receiver performing these methods, respectively. The invention suggests a scheme for communicating channel quality measures that on the one hand allows for an accurate reconstruction of the channel quality measures at the receiver and on the other hand requires an acceptable transmission overhead. This is achieved by partitioning channel quality measures into at least two partitions and to compress the values partition-wise, for example by means of a discrete cosine transform and the transmission of only a subset of the resulting coefficients.
