Description

ABSTRACT:
Systems and methodologies are described that facilitate performing interference nulling and rank prediction in an access terminal. Multiple receiver demodulator types may be implemented at the access terminal, and an interference covariance matrix may be estimated thereat. SNRs may be calculated for the various receiver demodulator types, and an optimum rank and associated CQI information may be identified and generated, respectively, which information may then be transmitted to an access point. At least one of the receiver demodulator types may perform an interference nulling protocol. For example, the receiver demodulator types may comprise at least one minimum mean-squared error interference-nulling (MMSE-IN) demodulator, along with and one or more of a maximal ratio combining (MRC) demodulator and a minimum mean-squared error (MMSE) demodulator.
