Abstract
Certain aspects of the present disclosure provide techniques for wireless communications. An example method includes receiving a configuration of a plurality of channel state information (CSI) reports; receiving an aperiodic CSI request that triggers transmission of CSI reporting, wherein the aperiodic CSI request indicates fewer CSI reports than the plurality of CSI reports; and transmitting the one or more CSI reports according to a rule that indicates a set of CSI reports, of the plurality of CSI reports, that are to be transmitted as the one or more CSI reports.
Claims20
An apparatus for wireless communications, comprising a processing system that includes one or more processors and one or more memories coupled with the one or more processors, the processing system configured to cause a user equipment (UE) to:
- receive a configuration of a plurality of channel state information (CSI) reports;
- receive an aperiodic CSI request that triggers transmission of CSI reporting, wherein the aperiodic CSI request indicates fewer CSI reports than the plurality of CSI reports;
- and
- transmit one or more CSI reports, of the plurality of CSI reports, according to one of:
- an ordering of indexes of the configuration of the plurality of CSI reports, or
- a mapping, indicated in the configuration, between the aperiodic CSI request and the one or more CSI reports.
A method for wireless communications by a user equipment (UE) comprising:
- receiving a configuration of a plurality of channel state information (CSI) reports;
- receiving an aperiodic CSI request that triggers transmission of CSI reporting, wherein the aperiodic CSI request indicates fewer CSI reports than the plurality of CSI reports;
- and
- transmitting one or more CSI reports, of the plurality of CSI reports, according to one of:
- an ordering of indexes of the configuration of the plurality of CSI reports, or
- a mapping, indicated in the configuration, between the aperiodic CSI request and the one or more CSI reports.
One or more non-transitory computer-readable media comprising executable instructions that, when executed by one or more processors of an apparatus, cause the apparatus to perform operations comprising:
- receiving a configuration of a plurality of channel state information (CSI) reports;
- receiving an aperiodic CSI request that triggers transmission of CSI reporting, wherein the aperiodic CSI request indicates fewer CSI reports than the plurality of CSI reports;
- and
- transmitting one or more CSI reports, of the plurality of CSI reports, according to one of:
- an ordering of indexes of the configuration of the plurality of CSI reports, or
- a mapping, indicated in the configuration, between the aperiodic CSI request and the one or more CSI reports.
