·
Multiple access scheme : Downlink:
OFDMA & Uplink: Single Carrier FDMA
(SC-FDMA)
·
Adaptive modulation and coding
·
DL modulations: QPSK, 16QAM, and 64QAM
·
UL modulations: QPSK and 16QAM
·
Rel-6 Turbo code: Coding rate of 1/3,
two 8-state constituent encoders, and a contention-free internal interleaver.
·
Bandwidth scalability for efficient
operation in differently sized allocated spectrum bands
·
Possible support for operating as
single frequency network (SFN) to support MBMS

Power control and link adaptation
·
Implicit support for interference
coordination
·
Support for both FDD and TDD
·
Channel dependent scheduling &
link adaptation for enhanced performance.
·
Reduced radio-access-network nodes to
reduce cost,protocol-related processing time & call set-up time
