Question: What is the definition of Time Alignment Error (TAE) for UE(s) with multiple transmit antenna connectors supporting UL-MIMO in the closed-loop spatial multiplexing scheme?
Option 1: The maximum frame timing difference between any two transmissions on different transmit antenna connectors.
Option 2: The average frame timing difference between any two transmissions on different transmit antenna connectors.
Option 3: The minimum frame timing difference between any two transmissions on different transmit antenna connectors.
Option 4: The total frame timing difference between all transmissions on multiple transmit antenna connectors.
Explanation: According to the definition, Time Alignment Error (TAE) is defined as the average frame timing difference between any two transmissions on different transmit antenna connectors for UE(s) with multiple transmit antenna connectors supporting UL-MIMO in the closed-loop spatial multiplexing scheme. This ensures that the transmissions from multiple antennas are aligned in time, which is crucial for proper signal processing and reception in wireless communication systems.
