Question: For a User Equipment (UE) supporting fourLayerTM3-TM4-perCC-r12, which of the following is a prerequisite for utilizing this capability in terms of bandwidth class composition?
Option 1: Bandwidth classes consisting of a single component carrier (e.g., Bandwidth Class A)
Option 2: Bandwidth classes that include multiple component carriers (e.g., Bandwidth Classes B, C, D, etc.)
Option 3: Any bandwidth class, regardless of the number of component carriers
Option 4: Only for TDD (Time Division Duplexing) mode in Bandwidth Class E
Explanation: This capability specifically pertains to UEs that can handle 4-layer spatial multiplexing with both Transmission Mode 3 and Transmission Mode 4 on a single component carrier within bandwidth classes that comprise multiple component carriers. This is crucial for efficient use of spectrum in multi-carrier configurations, enhancing overall network capacity and user experience in environments where such advanced bandwidth classes (e.g., B, C, D) are utilized.
