Power headroom reporting for systems with multiple transmission time intervals

Abstract

Methods, systems, and devices for wireless communication are described. Separate or combined transmissions of power headroom reports for transmission time intervals (TTIs) having different durations may be transmitted. For example, a user equipment (UE) may be configured to communicate with TTIs of different durations. The UE may identify a transmission power for a first TTI having a first duration and calculate a power headroom based on a maximum transmission power of a serving cell and the transmission power for the first TTI. The UE may determine a power headroom for another TTI having a different duration (e.g., a duration longer than the first duration) and transmit separate power headroom reports for each TTI duration. Additionally or alternatively, the UE may calculate a power headroom associated with both TTI durations and transmit a joint power headroom report for both TTI durations.
