Patent ID: 8144797

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 stored in a non-volatile memory region of the wireless device, the CQI table comprising all 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 a CQI index based on the mapping, wherein lower indices of the CQI table correspond to a first transmission mode, and wherein higher indices of the CQI table correspond to a second transmission mode, and wherein the first transmission mode comprises a space frequency block coding and frequency switched transmit diversity (SFBC-FSTD) MIMO mode.
