Abstract:
1. A method for providing channel quality feedback in an Orthogonal Frequency Division Multiplexing communication system, wherein a frequency bandwidth is represented by a plurality of Resource Block Group (RBG) levels, wherein each RBG level comprises a division of the frequency bandwidth into a number of Resource Block Groups (RBGs) different from the number of RBGs of the other RBG levels, and wherein the method comprises: measuring a channel quality associated with one or more RBGs of one or more RBG levels of the plurality of RBG levels; selecting an RBG from among the measured RBGs based on the measured channel quality, wherein selecting further comprises: reporting channel quality information associated with the selected RBG to a radio access network, wherein reporting comprises providing an index to the selected RBG and providing channel quality information for the indexed RBG.
