Abstract
Certain aspects of the present disclosure relate to methods and apparatus for reporting aperiodic channel quality indicator (A-CQI) in a new Secondary Cell (SCell) state of Long Term Evolution (LTE) carrier aggregation. A User Equipment (UE) receives a request for reporting A-CQI relating to a Scell configured for the UE when the UE is in a first state corresponding to the Scell, the first state designed for a reduced SCell activation latency and to result in the UE using lower power as compared to when the UE is in a second state. The UE, in response to the request, reports the A-CQI for the Scell in accordance with a first A-CQI reporting configuration for the first state which is different from a second A-CQI reporting configuration for the second state.
