Techniques and apparatuses for uplink power control

A method of wireless communications by a wireless communications device, comprising:

• associating a power headroom report (PHR) with at least one of a discrete Fourier transform spread orthogonal frequency-division multiplexing (DFT-s-OFDM) based waveform or a cyclic prefix orthogonal frequency-division multiplexing (CP-OFDM) based waveform, wherein the PHR is associated with a power headroom for a remaining one of the DFT-s-OFDM based waveform or the CP-OFDM based waveform by an offset;
• generating the first type of PHR;
• and
• transmitting the generated first type of PHR.

A method of wireless communications by a wireless communications device, comprising:

• associating a first type of power headroom report (PHR) with a discrete Fourier transform spread orthogonal frequency-division multiplexing (DFT-s-OFDM) based type of uplink transmission, and associating a second type of PHR with a cyclic prefix orthogonal frequency-division multiplexing (CP-OFDM) based type of uplink transmission;
• generating at least one of the first type of PHR or the second type of PHR;
• and
• transmitting the generated at least one of the first type of PHR or the second type of PHR.

A method of wireless communications by a wireless communications device, comprising:

• determining whether to use a cyclic prefix orthogonal frequency-division multiplexing (CP-OFDM)-based waveform or a discrete Fourier transform spread orthogonal frequency-division multiplexing (DFT-s-OFDM)-based waveform for an uplink transmission;
• and
• selectively using a first maximum transmit power or a second maximum transmit power to determine a transmit power for the uplink transmission based at least in part on the determining whether to use the CP-OFDM-based waveform or the DFT-s-OFDM-based waveform,
• wherein the first maximum transmit power is different from the second maximum transmit power.
