Abstract

Apparatus and method for: controlling 704 the measurement of a radio channel to obtain information on Signal to Interference and Noise Ratio (SINR) of a radio channel; calculating 708 a Channel Quality Index (or Channel Quality Information), CQI, on the basis of the information on Signal to Interference and Noise Ratio (SINR), the selection of the channel quality index table the index points to and the indexing method having been made utilising information on radio channel measurements controlled by the apparatus 706; and controlling 712, 714 the transmission of the channel quality index to the communication system. A User Equipment, UE, 116, Figure 1 may perform the SINR measurements and report the associated CQI to a nodeB, 106, Figure 1. The nodeB may indicate 708 to the UE the most appropriate indexing table or indexing method based on an initial radio channel measurement 704, 706, such as a Reference Signal Received Power, RSRP measurement for LTE or Received Signal Code Power on Common Pilot Indicator Channel, CPICH RSCP, or CPICH Ec/N0, Energy per chip to the Spectral Noise Density on Common Pilot Indicator Channel in WCDMA. As is typical the reported CQI information may allow the nodeB to determine the most appropriate Modulation and Coding Scheme, MCS, for the current channel conditions. A continuous subset of indices pointing a channel quality index table may be used. Different channel quality index tables may be used for real or complex valued modulation methods (Figure 6C). Performance differences between different indices of the channel quality index table may be non-uniform.
