Abstract

See full text

Methods, systems, and devices for wireless communication are described A user equipment (UE) and a base station may support switching from one waveform to another on uplink channels. For example, a UE and a base station may utilize both frequency division multiplexing (SC-FDM) waveform and an orthogonal frequency division multiplexing (OFDM) waveforms based on channel conditions and other factors. In some examples, a UE may switch for some uplink channels, and use a single waveform for other channels. For example, switching waveforms for channels that utilize frequency domain code division multiplexing (CDM) channel may interrupt the orthogonality of multiplexed transmissions. A UE may transition from one waveform to another either autonomously or based on an explicit indication from a base station. If a UE switches autonomously, it may send an indication of the transition to the serving base station.
