Question: What is a prerequisite for a User Equipment (UE) to support SRS coverage enhancement without SRS comb 4 in an E-UTRA network?
Option 1: The UE must also support ce-ModeA and cannot support ce-SRS-Enhancement.
Option 2: The UE is required to support both SRS comb 2 and SRS comb 4 simultaneously.
Option 3: The UE needs to indicate support for ce-SRS-Enhancement but not ce-ModeA.
Option 4: There are no specific prerequisites for SRS coverage enhancement features.
Explanation: To ensure compatibility and proper functionality, a UE that supports SRS coverage enhancement without SRS comb 4 must also support ce-ModeA. Additionally, it cannot support the more general ce-SRS-Enhancement, indicating a specific configuration requirement for this particular enhancement. This prerequisite ensures UEs are configured correctly to utilize the specified SRS enhancements efficiently in E-UTRA networks.
