Reporting of radio channel quality

Abstract:

Embodiments of systems and methods relating to a first radio device (UE) and a second radio device (base station) are disclosed. In some embodiments, a method implemented in the second radio device for adaptation of transmission over a radio channel is described. The method comprises determining a condition of the radio channel in which the radio channel exhibits an invariance of statistics and transmitting a data symbol to the first radio device via the radio channel. The method further comprises receiving a quality report of the radio channel from the first radio device based on the data symbol when a statistical characterization of the radio channel exceeds a predetermined threshold. The transmission over the radio channel is adapted by the second radio device based on the received quality report.
