17 Modulation & Waveform QPSK, 16QAM, 64QAM and 256QAM (with the same constellation mapping as in LTE) are supported OFDM-based waveform is supported. At least up to 40 GHz, CP-OFDM waveform supports spectral utilization of Y greater than that of LTE (assuming Y=90% for LTE) Where Y (%) is defined as transmission bandwidth configuration/channel bandwidth * 100%. Note: Y proposals example is 98% (For UL only) DFT-S-OFDM based waveform is also supported Limited to a single stream transmissions Targeting for link budget limited cases. Both CP-OFDM and DFT-S-OFDM based waveforms are mandatory for UEs

18 Channel Coding Channel coding techniques for NR should support info block size K flexibility and codeword size flexibility Rate matching (i.e., puncturing and/or repetition) supports 1-bit granularity in codeword size. Channel coding technique for data channels of NR support both Incremental Redundancy (IR) and Chase CFor very small block lengths where repetition/block coding may be preferred ombining (CC) HARQ.

19 MIMO in New Radio Downlink precoding is UE transparent Reference signals are also precoded similar to the data Up to 32 antenna ports are supported in the DL Antenna ports may not map to a physical antenna port Defined as channel over which a symbol on the antenna port is conveyed can be inferred from the channel over which another symbol on the same antenna port is conveyed Up to 8-layer MIMO is supported in the DL Hybrid beamforming-based MIMO (for mmwave) using various phased arrays panels are supported
