Abstract:
In an Orthogonal Frequency Division Multiplexing communication system, wherein frequency bandwidth may be represented by multiple Resource Block Group (RBG) levels, wherein each RBG level comprises a division of the frequency bandwidth into a number of RBGs different from the number of RBGs of the other RBG levels, a user equipment measures a channel quality associated with one or more RBGs of one or more RBG levels of the multiple RBG levels, selects an RBG of from among the measured RBGs based on the measured channel qualities, and reports 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.
