1. A method performed by a wireless device, comprising:
selecting a power headroom value of a first cell among:
a first power headroom value of an uplink transmission via uplink resources of the first cell, and
a second power headroom value of a sidelink transmission via a sidelink resource pool of the first cell; and
transmitting a power headroom report comprising the power headroom value of the first cell and a power headroom type indicating whether the power headroom value of the first cell is for the uplink transmission or the sidelink transmission,
wherein the second power headroom value is determined (1) based on an actual sidelink transmission when the wireless device is configured with a mode 1 sidelink operation in which resource assignments for the sidelink transmission are received from a base station, and (2) based on a sidelink reference format that is a virtual power headroom value when the wireless device is configured with a mode 2 sidelink operation in which resource assignments for the sidelink transmission are not received from the base station.
