1. A method for use in a wireless device configured to communicate with a base station via a plurality of cells, the method comprising:
receiving, by the wireless device from the base station, at least one radio resource configuration (RRC) message comprising:
a first power headroom parameter indicating whether an enhanced extended power headroom report format is setup; and
a second power headroom parameter indicating whether power headroom reporting is setup,
wherein the first power headroom parameter indicates that the enhanced extended power headroom report format is setup based on:
a secondary cell of the plurality of cells being configured with a physical uplink control channel (PUCCH); and
the second power headroom parameter indicating that power headroom reporting is setup for the plurality of cells; and
transmitting, based on the first power headroom parameter indicating that the enhanced extended power headroom report format is setup, a media-access-control (MAC) packet, formatted according to the enhanced extended power headroom report format, comprising:
a first Type 2 power headroom field of a primary cell in the plurality of cells; and
a second Type 2 power headroom field of the secondary cell based on the secondary cell being activated.
