摘要： The invention relates to different methods for reporting channel quality reports in a mobile communication system. Further, the invention relates to a reporting entity (e.g. mobile terminal) and a receiving entity (e.g. base station) which receives the channel quality reports. In order to propose a scheme for efficiently reporting channel quality of individual resource block groups in a mobile environment the invention provides a more efficient compression for the indication of the resource blocks/coefficients/partitions reported on in a channel quality report. This may be achieved by indicating the transitions between two resource block group sequences / coefficient index sequences / partition index sequences e.g. by applying a differential encoding. Furthermore, the maximum number of transitions that may be reported relative to another (differentially encoded or non-differentially encoded) sequence may be limited so as to further reduce the signalling overhead.
