Abstract:
A configurable new radio (NR) uplink (UL) transmission may use transmit diversity. A user equipment (UE) may identify an uplink transmission of at least one stream as using one of cyclic prefix orthogonal frequency division multiplexing or discrete Fourier transform spread orthogonal frequency division multiplexing. The UE may apply a precoding matrix to the at least one identified stream. The precoding matrix changes over time. The precoding matrix may change based on closed loop feedback, a precoding cycling pattern, and/or a code division multiplexing group. The UE may transmit the at least one identified stream from multiple antennas according to the applied precoding matrix.
