1. A method of wireless communications by a user equipment (UE) capable of MIMO, comprising:
receiving a configuration, from a base station, that includes a set of parameters for periodic and aperiodic channel state information (CSI) reporting, wherein the set of parameters comprise an indication of at least one of what resources to measure or what information to report, wherein the configuration comprises a configuration for a composite resource constructed from a plurality of CSI-RS resources configured for measuring and reporting CSI, wherein the set of parameters comprises a first set of information for periodic CSI reporting and a second set of information for aperiodic CSI reporting, wherein the first set of information is different than the second set of information, wherein the composite resource includes a first number of CSI-RS ports, wherein each of the plurality of CSI-RS resources includes a second number of CSI-RS ports, and wherein the first number of CSI-RS ports is greater than the second number of CSI-RS ports; and
measuring and reporting periodic and aperiodic CSI according to the configuration.
