Patent ID: 8611453

Claim:
A wireless device comprising: a receiver for receiving a reference signal; a first circuitry for calculating an average signal-to-noise ratio from the received reference signal; a channel quality indicator (CQI) table comprising a plurality of multiple input multiple output (MIMO) modes used in a transmission mapped over a range of signal-to-noise ratio; and a second circuitry for mapping the calculated average signal-to-noise ratio to the signal-to-noise ratio of the CQI table, the second circuitry selecting feedback information based on the mapping, wherein a first group of entries of the CQI table corresponds to a first transmission mode, and wherein a second group of entries of the CQI table corresponds to a second transmission mode, wherein the first and second transmission modes are different from one another, and wherein the first transmission mode comprises a space frequency block coding (SFBC) MIMO mode.
