Question: Which of the following statements is true regarding the support for `ceMeasurements-r14` in E-UTRA UEs, as per the latest specifications?
Option 1: All UE categories are mandatorily required to support `ceMeasurements-r14`.
Option 2: Only UEs supporting coverage enhancements are required to support `ceMeasurements-r14`, regardless of their category.
Option 3: Support for `ceMeasurements-r14` is mandatory specifically for UEs of Category M1, M2, and those that support coverage enhancements.
Option 4: There is no mandatory requirement for any UE category to support `ceMeasurements-r14`.
Explanation: This option accurately reflects the specification's mandate. It highlights that UEs categorized as M1 and M2, along with those designed to support coverage enhancements, are required to support `ceMeasurements-r14`. This ensures these UEs can perform necessary measurements in RRC_CONNECTED mode, enhancing network efficiency and user experience.
