Abstract
A method, computer program, device and system are provided for determining channel state information for use in a wireless communications network. The channel state information includes a rank indicator (RI), precoding matrix index (PMI) and channel quality indicator (CQI). The RI, PMI or CQI can be determined based on channel covariance estimation and the Taylor series approximation of its inverse. Further, the RI and PMI can be determined separately.
