1. A method comprising:
processing scheduling information, received from a base station, to schedule a plurality of repetitions of an uplink data transmission over a first component carrier (CC);
detecting, by a user equipment (UE), a power headroom report (PHR) trigger condition;
calculating, based on the detecting, a first power headroom value for a first actual repetition of the plurality of repetitions;
calculating a second power headroom value for a second actual repetition of the plurality of repetitions, wherein calculating the second power headroom value is based on:
an assumption of no uplink data transmission by the UE over a second CC during the second actual repetition, or
an assumption that an uplink data transmission status of the UE over a second CC during the second actual repetition is equivalent to an uplink data transmission status of the UE over the second CC during the first actual repetition; and
generating a report, for transmission to the base station, including a first PHR based on the first power headroom value and a second PHR based on the second power headroom value.
