Hi bro,

The answer to your question would be YES, if the configured CSI feedback type supports RI reporting.

As per the 36.213 Rel 11 - 7.2 :
A UE shall transmit aperiodic CSI reporting on PUSCH if the conditions specified hereafter are met. For aperiodic CQI/PMI reporting, RI reporting is transmitted only if the configured CSI feedback type supports RI reporting.

Regards,
Hareesh

The UE might send the aperiodic cqi report on the PUSCH when the enodeB requests it. My question is, WHY does the eNB want the UE to send an aperiodic cqi report when it is already reporting a periodic cqi report. What is the trigger for the eNode to ask the UE to send an aperiodic cqi report ?
