Question: In a Single RAT E-UTRA operation for an Active Antenna System (AAS) Base Station (BS), how are spurious emission limits adjusted for each TAB connector TX min cell group, based on the number of transmit antennas (NTXU) counted per cell?
Option 1: The basic limit is increased by 10log10(NTXU), where NTXU is the number of transmit antennas counted per cell.
Option 2: The basic limit remains unchanged regardless of the number of transmit antennas (NTXU) counted per cell.
Option 3: The basic limit is decreased by 10log10(NTXU), where NTXU is the number of transmit antennas counted per cell, for each additional antenna.
Option 4: The adjustment depends solely on regional regulations and not on the number of transmit antennas (NTXU).
Explanation: According to specifications for AAS BS in single RAT E-UTRA operation, the spurious emission limit for each TAB connector TX min cell group is adjusted by adding X to the basic limit, where X equals 10log10(NTXU), with NTXU being the number of transmit antennas counted per cell. This adjustment accounts for combined emissions from multiple antennas in a cell group, ensuring compliance with spurious emission requirements.
