Question: What is the primary approach to supporting Layer-1 features in a User Equipment (UE) with Reduced Capabilities (RedCap UE), according to 3GPP standards?
Option 1: Only supports Layer-1 features through explicit capability signaling.
Option 2: Supports all optional Layer-1 features without any exceptions.
Option 3: Supports all mandatory Layer-1 features without capability signaling, unless otherwise stated.
Option 4: Does not support any Layer-1 features described for a standard UE.
Explanation: This is correct because, as per the 3GPP standards for RedCap UEs, these devices maintain core functionality while reducing complexity. Thus, they support all mandatory Layer-1 features inherently (without needing explicit capability signaling), except in cases where an exception is explicitly noted, ensuring basic operational compatibility with reduced capabilities.
