    Abstract: For multiplexing channel state information (CSI), a user equipment (UE) includes a transceiver configured to receive configuration information for CSI reporting and a processor configured to decode the configuration information and calculate a CSI according to the configuration information. The transceiver is configured to transmit the calculated CSI on an uplink (UL) channel, where the CSI includes N segments and is transmitted in one slot, where N>1. A first of the N segments includes a rank indicator (RI) and at least one other CSI parameter. A base station (BS) includes a processor configured to generate configuration information for CSI reporting and a transceiver configured to transmit, to a UE, the configuration information via a downlink (DL) channel; and receive, from the UE, a CSI report calculated in accordance with the configuration information on an uplink UL channel.
