Abstract
A wireless device receives message(s) comprising configuration parameters of a plurality of cells for communication with a base station. The message(s) comprise a first information element (IE) indicating a new extended power headroom report is configured. The first IE is configured as setup when: a secondary cell is configured with a physical uplink control channel (PUCCH) and a second IE indicates that a power headroom report is configured as setup. The wireless device transmits a media-access-control (MAC) packet comprising one or more power headroom reports.

A method comprising:
- receiving, by a wireless device from a base station, at least one radio resource configuration (RRC) message comprising:
- a power headroom parameter indicating whether an extended power headroom report format is setup,
- wherein the extended power headroom report format is configured as setup based on a secondary cell of a plurality of cells being configured with a physical uplink control channel (PUCCH);
- and
- transmitting, based on the extended power headroom report format being setup, an extended power headroom report media-access-control (MAC) control element comprising:
- a first Type 2 power headroom field corresponding to a primary cell of the plurality of cells;
- and
- a second Type 2 power headroom field corresponding to the secondary cell of the plurality of cells.
