Abstract
A downlink Channel Quality Indicator (CQI) is estimated in two steps. Initially, one or more subsets of received reference symbols are selected. If the transmitter may transmit signals in one or more of two or more frequency bands, optimal frequency bands are selected based on a first subset of reference symbols. If the transmitter may transmit using one of two or more VACs, an optimal VAC is selected based on the first or a second subset of reference symbols. An SINR is subsequently calculated for the selected frequency band and VAC combination, based on more than the subset(s) of reference symbols.
