1. A method comprising:
receiving, by a wireless device, a preamble power parameter that is for beam failure recovery associated with a cell and that is different from a preamble power parameter for random access associated with the cell; and
transmitting, via a random access channel and using a transmission power that is based on the preamble power parameter for beam failure recovery, a preamble for beam failure recovery associated with a beam failure of the cell.
