Question: In E-UTRA, for a User Equipment (UE) supporting short TTI, what does the value 'n3' of the sTTI-SupportedCSI-Proc-r15 field indicate about CSI processes on a component carrier within a band?
Option 1: Support for up to 2 CSI processes
Option 2: Support for exactly 1 CSI process
Option 3: Support for exactly 3 CSI processes
Option 4: No support for CSI processes on that band
Explanation: The value 'n3' indicates the UE's capability to support exactly 3 Channel State Information (CSI) processes on a component carrier within a specific band, enhancing network performance and user experience through more precise channel state feedback.
