Abstract:
1. A method of estimating channel quality in a receiver having one or more receive antennas and operative in a wireless communications system in which data and reference symbols are transmitted from one or more transmit antennas, comprising: receiving a plurality of reference symbols; selecting one or more subsets of the received reference symbols; determining whether a transmitter may transmit in one or more of two or more frequency bands, and if so, selecting an optimal set of frequency bands based on a first subset of reference symbols; determining whether the transmitter may transmit using one of two or more Virtual Antenna Combinations (VAC), and if so, selecting an optimal VAC based on the first or a second subset of reference symbols; and estimating a signal to interference and noise ratio (SINR) for the transmission channel in the selected frequency bands and/or VAC using more than the first subset of reference symbols.
