26. LTE FDD E-TM 1.1 and E-TM 3.1, 10 MHz, 64 QAM PDSCH, full resource block, ≤ +6 dBm.
27. MIMO performance data applies when each channel is configured with its own independent synthesizer. Sharing a single synthesizer will degrade EVM
performance approximately 1 dB.
28. LTE FDD/TDD MIMO R9 downlink, full filled 64 QAM 10 MHz (50 RB), at 0 dBm, open-loop spatial multiplexing transmission mode.
29. LTE FDD/TDD 10 MHz BW, DL, TM9 multi-layer, TM4 closed-loop spatial multiplexing transmission mode.
