1. A method comprising:
receiving, by a wireless device, configuration information indicating:
a first time alignment timer value associated with a first cell group; and
a second time alignment timer value associated with a second cell group;
transmitting, via the second cell group and during a time period in which a first time alignment timer of the first cell group is running, a preamble as part of a random access process; and
based on an expiration of the first time alignment timer and after receiving a random access response corresponding to the preamble, aborting the random access process.
