Question: What is a prerequisite for a User Equipment (UE) to support pusch-SPS-SubslotRepPCell-r15 in an FDD (Frequency Division Duplexing) system?
Option 1: The UE must also support semiStaticCFI-r15 and indicate capabilities for both subslot PUSCH and SPS for subslot PUSCH.
Option 2: The UE only needs to support TDD (Time Division Duplexing) mode in addition to FDD.
Option 3: The UE has to be capable of operating solely in LTE (Long-Term Evolution) bands below 1 GHz.
Option 4: There are no additional prerequisites; supporting pusch-SPS-SubslotRepPCell-r15 is sufficient on its own.
Explanation: According to the specifications, for a UE to support pusch-SPS-SubslotRepPCell-r15 (SPS repetition for subslot PUSCH for PCell in FDD), it must also indicate support for semiStaticCFI-r15 and have capabilities for both subslot PUSCH and SPS for subslot PUSCH. This ensures the UE can properly manage and utilize these advanced features within the constraints of an FDD system.
