Abstract
Certain aspects of the present disclosure provide techniques for performing periodic and aperiodic CSI reporting for MIMO operations. According to certain aspects, operations for performing periodic and aperiodic CSI reporting for MIMO generally includes configuring a user equipment (UE) that is capable of MIMO with different parameters for periodic and aperiodic channel state information (CSI) reporting, wherein the different parameters indicate at least one of what resources to measure or what information to report, and receiving periodic and aperiodic CSI reporting from the UE according to the configuration.

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.
An apparatus for wireless communications by a user equipment (UE) capable of MIMO, comprising:
- memory having executable instructions stored thereon;
- and
- one or more processors configured, individually or collectively, to execute the executable instructions and cause the apparatus to:
- receive 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
- measure and reporting periodic and aperiodic CSI according to the configuration.
An apparatus for wireless communications by a user equipment (UE) capable of MIMO, comprising:
- means for 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;
