Question: What action does a User Equipment (UE) take when estimating a Transport Format Combination (TFC) requires more power than its maximum transmit power in a TDD (Time Division Duplexing) system?
Option 1: The UE selects an alternative TFC from the assigned set that can be transmitted at or below the maximum transmit power to maintain coverage.
Option 2: The UE automatically increases its maximum transmit power to accommodate the selected TFC, ensuring data transmission at all costs.
Option 3: The UE drops the assignment and requests a new Transport Format Combination Set from the network to avoid power issues.
Option 4: The UE proceeds with transmitting the estimated TFC at reduced power, potentially leading to transmission errors.
Explanation: To maximize coverage as intended by the network operator, the UE must adapt its transmission strategy when faced with power constraints. Selecting an alternative TFC that fits within the maximum transmit power ensures reliable communication without overextending the UE's capabilities, thus maintaining optimal coverage. This approach aligns with efficient resource management and quality of service (QoS) in wireless communications.
