1. A method comprising:
receiving, by a wireless device, configuration parameters of timing advance groups (TAGs) comprising:
a primary TAG comprising a primary cell; and
a secondary TAG comprising one or more licensed secondary cells and one or more unlicensed secondary cells; and
transmitting uplink signals via the secondary TAG with transmission timing derived employing a first secondary cell, of the secondary TAG, that is based on the first secondary cell being:
an activated secondary cell; and
a licensed secondary cell.
