WHAT UL TRANSMISSION SCHEME IS USED?

In case of FDD and TDD, the uplink transmission scheme is based on low peak to average power ratio (PAPR) scheme. It is termed as single carrier frequency division multiple access (SC-FDMA) scheme with cyclic prefix to achieve uplink inter-user orthoganality and to enable efficient frequency domain equalization at the receiver side.

Scheduling operates on a sub-frame level (i.e., 1 msec basis ) . Uplink data modulation schemes are QPSK, 16 QAM and 64 QAM.
