Question: What does the `nMaxProc` field, related to aperiodic NZP (Non-Zero Power) CSI-RS (Channel State Information Reference Signal) transmission in E-UTRA, specifically indicate about UE radio access capabilities?
Option 1: Maximum number of simultaneous transmission modes (e.g., TM9, TM10) supported for aperiodic NZP CSI-RS.
Option 2: Maximum number of updated CSI processes for aperiodic NZP CSI-RS transmissions.
Option 3: Total bandwidth available for aperiodic NZP CSI-RS resource allocation in a cell.
Option 4: Minimum processing delay for UE to respond to aperiodic NZP CSI-RS requests.
Explanation: The `nMaxProc` field is directly related to the maximum number of updated Channel State Information (CSI) processes that can be handled for aperiodic Non-Zero Power CSI Reference Signal transmissions, impacting the UE's ability to provide timely and accurate channel state feedback for optimized network transmission settings.
