Abstract

This disclosure addresses rank indicator and channel quality indicator CQI estimation and reporting functionality with respect to heterogeneous networks to reduce the number of inconsistent CQI estimates transmitted to eNodeB eNBs where the rank indication of the CQI is adjusted when above The CQI is defined as inconsistent when it is from a different subframe type than the subframe on which the CQI is to be estimated.
