<P>PROBLEM TO BE SOLVED: To provide systems and methods for facilitating interference nulling and rank prediction in an access terminal. <P>SOLUTION: A plurality of receiver demodulator types are implemented to the access terminal, and an interference covariance matrix is estimated at the access terminal. SNRs are calculated for the various receiver demodulator types, and an optimum rank and associated CQI information are identified and generated, respectively, and the information is then transmitted to an access point. At least one of the receiver demodulator types performs an interference nulling protocol. The receiver demodulator types comprise at least one minimum mean-squared error interference-nulling (MMSE-IN) demodulator, along with one or more of a maximal ratio combining (MRC) demodulator and a minimum mean-squared error (MMSE) demodulator. <P>COPYRIGHT: (C)2012,JPO&INPIT |
