1. A method for wireless communication at a user equipment (UE), comprising:
receiving control signaling indicating a time interval over which to determine available power headroom relative to a transmission power threshold;
calculating, based at least in part on the control signaling, the available power headroom as a difference between the transmission power threshold and a statistical transmission power value calculated across a plurality of uplink carriers during within the time interval; and
transmitting a power headroom report indicating the calculated available power headroom based at least in part on a condition for transmitting the power headroom report being satisfied, the condition being that the calculated available power headroom satisfies an expected available power headroom threshold indicating additional transmit power is available at the UE.
