1. A user equipment (UE) configured for wireless communication, the UE comprising:
at least one processor; and
a memory coupled to the at least one processor,
wherein the at least one processor is configured to:
determine an uplink physical uplink control channel (PUCCH) or physical uplink shared channel (PUSCH) transmission power headroom value using a maximum configured transmission power of the UE and an uplink PUCCH or PUSCH transmission power configured for an uplink transmission at a configured modulation and coding scheme (MCS);
determine a reference resource signal power headroom value per MCS value of a plurality of candidate MCS values using the maximum configured transmission power and a reference resource signal transmission power configured for a reference resource signal transmission, wherein the reference resource signal transmission power is different than the uplink PUCCH or PUSCH transmission power;
calculate a reference resource power headroom differential per the MCS value equal to a difference between the uplink PUCCH or PUSCH transmission power headroom and the reference resource signal power headroom value per MCS value; and
transmit a power headroom report (PHR) to a serving network entity, wherein the PHR includes a field holding the uplink PUCCH or PUSCH transmission power headroom value and another field holding the reference resource power headroom differential per the MCS value.
