Abstract
A method and network node for single user multiple input multiple output (SU-MEMO) codebook-based precoder selection and for rank adaptation are provided. According to one aspect, a method includes, for each one of a plurality of rank hypotheses: selecting a precoder matrix based on an uplink transmit covariance matrix; and estimating a respective information carrying capacity, ICC, for the rank hypothesis based at least in part on the selected precoder matrix. The method further includes selecting an uplink SU-MIMO precoding matrix based at least in part on the estimated ICC for each rank hypothesis.
