Abstract

It is described a method for transmitting channel quality information between a second network element and a first network element. The method comprises includes (a) dividing a range of possible radio channel qualities between the two network elements into a fixed number of quality classes, (b) measuring the quality of a radio channel between the two network elements, (c) selecting one quality class out of the fixed number of quality classes based on the measured quality of the radio channel, (d) transmitting from the second network element to the first network element a first channel quality information being indicative for the selected quality class, and (e) transmitting from the second network element to the first network element a second channel quality information being indicative for the measured quality within the limits of the selected quality class. It is further described the first and the second network element, which in conjugation with each other are adapted to carry out the described method.
