Scheduling of PDSCH transmission with DFT-s-OFDM waveform

A wireless communication apparatus, comprising:

• a base station (BS) configured to:
• indicate a time domain resource allocation within one Discrete Fourier Transform (DFT) size in a downlink control information (DCI), wherein the one DFT size equals a number of subcarriers allocated for transmission within one Orthogonal Frequency Division Multiplexing (OFDM) symbol;
• and
• transmit, following a DFT operation, a physical downlink shared channel (PDSCH) with a Discrete Fourier Transform-spread-Orthogonal Frequency Division Multiplexing (DFT-s-OFDM) waveform in accordance with the time domain resource allocation within the one DFT size;
• multiplex a plurality of PDSCHs for one or more user equipments (UEs) in a time division multiplexing (TDM) manner;
• and
• perform the DFT operation on the multiplexed plurality of PDSCHs,
• wherein the BS performs a multiple-step resource allocation for the plurality of PDSCHs with the DFT-s-OFDM waveform, and
• wherein prior to performing the DFT operation, determining, by the BS, a time resources allocation of modulated symbols for PDSCH transmission within the one DFT size, and determining, by the BS, a frequency domain resource allocation and resource mapping after performing the DFT operation.
