Question: What is the primary implication of a User Equipment (UE) supporting 'dmrs-LessUpPTS-r14' in an E-UTRA network?
Option 1: The UE can transmit DMRS for PUSCH in UpPTS with reduced power consumption.
Option 2: The UE does not transmit DMRS for PUSCH in UpPTS, potentially enhancing uplink capacity in specific TDD configurations.
Option 3: The UE is required to always transmit DMRS for PUSCH in both UpPTS and normal subframes.
Option 4: This feature enables the UE to receive additional control signaling in UpPTS.
Explanation: Supporting 'dmrs-LessUpPTS-r14' means the UE can operate without transmitting Demodulation Reference Signals (DMRS) for Physical Uplink Shared Channel (PUSCH) in the UpPTS, potentially enhancing uplink capacity in specific TDD scenarios by reducing overhead.
