Abstract
Channel state information (CSI) can be transmitted to a network node incrementally to increase network efficiency. The CSI feedback framework can be enhanced by allowing a user equipment (UE) to report multiple sets of CSI feedback, where each set can comprise a rank indicator (RI), a pre-coder matrix indicator (PMI), and a channel quality indicator (CQI). Since a different set may have a different sub-band, the CSI feedback framework can support the sub-band rank, wherein rank data from a wideband and the sub-band can be used by the network.
