Yes, LTE designed to Support both paired and unpaired spectrum i.e. FDD and TDD mode.
Q What type of modulation scheme and multiple access is used in LTE?
Multiple modulation scheme used in LTE both in downlink and uplink direction.
Downlink – QPSK, 16QAM and 64QAM
Uplink – QPSK, 16QAM and 64QAM (Based on UE support)
OFDMA (Orthogonal frequency division multiple access) is used in LTE in downlink direction and SC-FDMA (Single carrier frequency division multiple access) is used in uplink direction.
